Description

Container for razor cartridges

The present disclosure relates to a container for a razor cartridge.

The material described in this section merely provides background information for the present disclosure and does not constitute prior art.

Razor cartridges are typically sold in a sealed container with a storage space inside. For example, razor cartridges may be sold sealed in a container containing a storage space inside. This prevents damage to the razor cartridge during transport or sale, and also prevents safety issues such as users being cut by the razor blade when opening the packaging.

To prevent the razor cartridge from moving within the container, most razor cartridges are fixedly supported within the container's holding space. Conventional containers require the user to apply force in the opposite direction of engagement to detach the razor cartridge from the container. This not only causes inconvenience to the user, but can also result in damage to the razor cartridge and/or the container due to excessive force.

Additionally, as environmental regulations are strengthening worldwide, such as banning or reducing the use of single-use plastics, the containers that house razor cartridges also need to meet these strengthened environmental regulations.

Accordingly, the present disclosure is intended to solve these problems, and its main purpose is to provide an environmentally friendly container for a razor cartridge, which allows easy separation of the razor cartridge while the razor cartridge is contained therein.

According to one embodiment of the present disclosure for achieving the above object, a container for a razor cartridge including at least one razor blade having a cutting edge extending in a longitudinal direction is provided, the container including: a housing; an opening portion formed by opening at least a portion of one side of the housing; and an accommodation space configured to accommodate the razor cartridge within the housing through the opening portion, wherein the housing includes a plurality of ground contact portions configured to come into contact with the ground when the other side of the housing opposite to the one side is placed on the ground, and the plurality of ground contact portions are spaced apart from each other in a transverse direction that is perpendicular to the longitudinal direction and parallel to the opening.

As described above, according to the present embodiment, there is an effect of providing an environmentally friendly container for a razor cartridge, in which the razor cartridge can be easily separated while the razor cartridge is contained.

Furthermore, when describing the present disclosure, detailed descriptions of related known structures or functions will be omitted if they are deemed to obscure the gist of the present disclosure.

In describing components of embodiments according to the present disclosure, symbols such as first, second, i), ii), a), b) may be used. These symbols are only for distinguishing the components from other components, and the nature, order, or sequence of the components are not limited by the symbols. When a part in the specification is said to "include" or "have" a component, this does not mean that other components are excluded, but rather that other components may be included, unless explicitly stated otherwise.

FIGS. 1A and 1B are exploded perspective views showing a state before a razor cartridge (10) is accommodated in a container for a razor cartridge (1) according to one embodiment of the present disclosure.

FIG. 2 is a drawing showing a state in which a razor cartridge (10) is accommodated in a container (1) for a razor cartridge according to one embodiment of the present disclosure.

FIGS. 3A to 3D are drawings showing only the housing (100) cut in the A-A' direction of FIG. 1A from a longitudinal perspective, with the razor cartridge (10) housed within the housing (100). For convenience of explanation, the razor cartridge (10) is shown in a side view rather than a cross-sectional view in FIGS. 3A to 3D.

FIG. 4 is a side view of a container (1) for a razor cartridge according to one embodiment of the present disclosure.

FIGS. 5A and 5B are drawings showing the state before the razor cartridge (10) is separated from the housing (100) by the razor handle (20) and the state after the housing (100) is cut along the B-B' direction of FIG. 1A and viewed in the longitudinal direction, with the razor cartridge (10) starting to be separated. For convenience of explanation, the razor cartridge (10) in FIGS. 5A and 5B is shown in a side view rather than a cross-sectional view.

Referring to FIGS. 1A, 1B, 2 and 3A to 3D, a container (1) for a razor cartridge according to one embodiment of the present disclosure can accommodate a razor cartridge (10).

The razor cartridge (10) may include at least one razor blade (15) having a cutting edge (not shown) extending longitudinally. The longitudinal direction may be a direction parallel to the X-axis in FIGS. 1A, 1B and 2.

Meanwhile, the surface toward which the cutting edge of at least one shaving blade (15) on the razor cartridge (10) faces can be defined as the cartridge upper surface (10_1), and the surface opposite to the cartridge upper surface (10_1) can be defined as the cartridge lower surface (10_2).

Referring further to FIGS. 4, 5a and 5b, a container (1) for a razor cartridge according to one embodiment of the present disclosure includes all or part of a housing (100), an opening portion (150), an accommodation space (155) and a sealing unit (200).

The opening (150) is formed by opening at least a portion of one side of the housing (100). An accommodation space (155) can be formed through the opening (150) and can accommodate a razor cartridge (10) within the housing (100).

The sealing portion (200) is configured to seal the opening (150). Through the sealing portion (200), the razor cartridge (10) accommodated in the accommodation space (155), particularly the first shaving aid unit (11) and the second shaving aid unit (19), which will be described later, can be prevented from coming into contact with external moisture. In addition, external contaminants, etc. can be prevented from entering the accommodation space (155).

The razor cartridge (10) can be distributed and sold in a state in which the sealing portion (200) is attached to the housing (100) after being accommodated in the housing (100), i.e., in a state in which the interior of the container (1) for the razor cartridge is sealed. The user can remove the sealing portion (200) attached to the housing (100) to separate the razor cartridge (10) from the outside of the container (1). Thereafter, the user can pull the razor handle (20) by connecting the razor handle (20) to the razor cartridge (10) through the opening (150), or the user can directly separate the razor cartridge (10) by hand.

When the sealing portion (200) is removed, the lower surface (10_2) of the cartridge can be exposed to the outside through the opening (150) in an accommodation state in which the razor cartridge (10) is accommodated in the accommodation space (155), and the razor handle (20) can be coupled to the lower surface (10_2) of the cartridge. It is preferable that the razor cartridge (10) does not protrude to the outside beyond the opening (150) in the accommodation state.

The housing (100) may include a plurality of ground contact portions (500). When the other side of the housing (100) opposite to one side is placed on the ground, the plurality of ground contact portions (500) may be configured to be in contact with the ground. Here, the ground is a surface that supports the plurality of ground contact portions (500) during normal use of the container (1) for the razor cartridge, and is assumed in this specification to be a plane that is in contact with the plurality of ground contact portions (500).

The plurality of ground contact portions (500) are spaced apart from each other in a lateral direction that is perpendicular to the longitudinal direction and parallel to the opening (150). The lateral direction may be a direction parallel to the Y-axis in FIGS. 1a, 1b, 2, 3a to 3d, and 4.

A container (1) for a razor cartridge according to one embodiment of the present disclosure can be supported from the ground by a plurality of ground contact portions (500) in a grounded resting state in which the plurality of ground contact portions (500) are resting on the ground.

In addition, referring to FIGS. 5A and 5B, since the plurality of ground contact portions (500) are laterally spaced apart from each other, at least a portion of the outer surface of the housing (100) facing the ground can be spaced apart from the ground. Accordingly, since moisture is not excessively absorbed onto the outer surface of the housing (100), the housing (100) can be prevented from coming into close contact with the ground.

Meanwhile, the user can use the razor handle (20) as a lever to separate the razor cartridge (10) from the housing (100) while the razor handle (20) is connected to the razor cartridge (10). In this case, the razor cartridge (10) can be more easily separated compared to the conventional technology of separating the razor cartridge (10) by applying force to the razor cartridge (10) in the opposite direction to the direction in which the razor cartridge (10) is connected to the housing (100).

Referring to FIGS. 1A, 1B, and 2, the razor cartridge (10) may include a first shaving aid unit (11) and a second shaving aid unit (19). The first shaving aid unit (11) and the second shaving aid unit (19) may each include one or more of soap and a lubricant. The first shaving aid unit (11) and the second shaving aid unit (19) may include the same components, but are not necessarily limited thereto.

The first shaving aid (11) may be positioned at the rear of at least one shaving blade (15), and the second shaving aid (19) may be positioned at the front of at least one shaving blade (15). Here, the front and rear are defined based on the shaving direction on the razor cartridge (10).

Also, referring to FIGS. 3A to 3D and FIG. 4, the housing (100) includes all or part of a rear wall (102), a front wall (108), a lower wall (106), a pair of longitudinal walls (104), at least one protruding portion (400) and at least one groove portion (450).

The rear wall (102) is a wall configured to face the rear side of the razor cartridge (10), and the front wall (108) is a wall configured to face the front side of the razor cartridge (10). The lower wall (106) is a wall configured to connect the rear wall (102) and the front wall (108) and face the cutting edge, and a pair of longitudinal side walls (104) are walls configured to face each of the longitudinal sides of the razor cartridge (10). The receiving space (155) can be formed by being surrounded by the rear wall (102), the front wall (108), the lower wall (106), and the pair of longitudinal side walls (104).

The lower wall (106) may further include at least one through hole (not shown). The at least one through hole may connect the receiving space (155) and the exterior of the lower wall (106). By virtue of the at least one through hole, air circulation and internal drainage between the receiving space (155) and the exterior may be achieved even in the receiving state. However, it is preferable that at least one through hole be formed in a fine size so that air circulation and internal drainage may be achieved while preventing the inflow of foreign substances.

Additionally, at least a portion of the lower wall (106) may be composed of a transparent material. In this case, the shape of the upper surface (10_1) of the razor cartridge (10) is exposed to the outside before the sealing portion (200) is removed, thereby providing an effective means of promoting the product. In addition, it is possible to easily check from the outside whether the razor cartridge (10) is accommodated in the accommodation space (155) and whether the razor cartridge (10) is defective.

In the receiving state, a pair of longitudinal side walls (104) may be configured to contact at least a portion of each of the longitudinal ends of the razor cartridge (10). In this case, longitudinal movement of the razor cartridge (10) may be restricted in the receiving state.

Additionally, in the receiving state, the razor cartridge (10) may be configured to be spaced apart from the front wall (108), the rear wall (102), and/or the lower wall (106). However, this is not necessarily limited thereto, and a detailed description thereof will be provided later.

Meanwhile, the housing (100) may further include an adhesion portion (140). The adhesion portion (140) may be formed to extend longitudinally and/or transversely along at least a portion of the perimeter of the opening (150). The adhesion portion (140) may provide a sufficient area with which the sealing portion (200) can make contact.

At least one protrusion (400) may be formed to protrude from the outer surface of the housing (100). For example, at least one protrusion (400) may be formed to protrude longitudinally from the outer surface of each of a pair of longitudinal side walls (104), so as to be configured as a pair on both longitudinal sides. At least one protrusion (400) on one longitudinal side wall (104) may include a plurality of protrusions (400) that are laterally spaced apart from each other.

When a user grips the housing (100), the contact force between the user's finger and the housing (100) can be increased by at least one protrusion (400), thereby making gripping easier.

At least one groove (450) may be formed by recessing at least a portion of the outer surface of the housing (100). For example, at least one groove (450) may be formed by recessing at each of the longitudinal ends of a pair of longitudinal side walls (104) and/or a lower wall (106), so as to form a pair on both longitudinal sides.

When a user grips the housing (100), the contact force between the user's finger and the housing (100) can be increased by at least one protrusion (400), thereby making gripping easier.

The degree of protrusion of the protrusion (400) and/or the degree of recessing of the groove (450) can be adjusted to suit the degree of contact with the user's finger, etc.

Meanwhile, when the housing (100) includes an adhesive portion (140), at least one step difference (145) may be formed at one end of the lateral side of the adhesive portion (140). When the adhesive portion (140) includes at least one step difference (145), the corner region (146) of the adhesive portion (140) may have a lower height than other regions based on the step difference (145). In this case, the sealing portion (200) may not be attached to the corner region (146) whose height is lowered by the step difference (145), and may be attached to the entire remaining region of the adhesive portion (140) excluding the corner region (146). At least one step difference (145) may be formed by a part of the adhesive portion (140) being sunken, but is not necessarily limited thereto.

A fine gap may be formed between the sealing portion (200) and the adhesive portion (140) by at least one step (145), which may facilitate the user's removal of the sealing portion (200). In addition, the sealing portion (200) may be prevented from being rolled up when press cutting is performed after the sealing portion (200) is attached to the adhesive portion (140) during the manufacturing process by at least one step (145).

Meanwhile, referring again to FIGS. 3A to 3D, the housing (100) in the receiving state and the settling state may include a first housing region (110), a second housing region (120), and a third housing region (130). The first housing region (110), the second housing region (120), and the third housing region (130) may be formed on the lower wall (106).

The first housing area (110) is an area that faces the ground and is configured to correspond to the position of the first shaving aid (11), and the second housing area (120) is an area that faces the ground and is configured to correspond to the position of the second shaving aid (19).

Specifically, when the opening (150) is parallel to the ground, the transverse ends of the first shaving aid (11) can define the boundary of the first housing area (110), and the transverse ends of the second shaving aid (19) can define the boundary of the second housing area (120).

Each of the first housing area (110) and the second housing area (120) may include at least a portion of each of the plurality of ground contact portions (500). Accordingly, in the receiving state, at least a portion of each of the plurality of ground contact portions (500) may correspond to the positions of each of the first shaving aid portion (11) and the second shaving aid portion (19).

In this case, based on the receiving state and the settling state, the central area of the shaving direction of the razor cartridge (10) can be placed between a plurality of ground contact portions (500) within the housing (100). Through this, even if the plurality of ground contact portions (500) are spaced apart, the housing (100) and the razor cartridge (10) received in the housing (100) can be stably supported by the ground.

The third housing area (130) is an area located between the first housing area (110) and the second housing area (120). Specifically, when the opening (150) is parallel to the ground, the boundary of the third housing area (130) can be defined by the boundary of the adjacent first housing area (110) and the boundary of the second housing area (120).

In the receiving state, at least a portion of the third housing area (130) may correspond to the position of at least one shaving blade (15). The razor handle (20) may be coupled to the razor cartridge (10) in an area of the razor cartridge (10) corresponding to the third housing area (130).

At least a portion of the third housing area (130) may be spaced apart from the ground in a settled state. This allows a space for a plurality of ground contact portions (500) to be secured. In addition, the space prevents excessive moisture from being absorbed onto the outer surface of the housing (100) facing the ground in a settled state, thereby preventing the housing (100) from coming into close contact with the ground.

Meanwhile, in order to secure sufficient contact area between the housing (100) and the ground in a settled state, the third housing area (130) may include at least a different portion of each of the plurality of ground contact portions (500), but is not necessarily limited thereto.

Referring to FIGS. 3a and 3c, when the opening (150) is parallel to the ground, the transverse midpoint of the first housing area (110) on the outer surface of the housing (100) is referred to as the first point (P1), the transverse midpoint of the second housing area (120) on the outer surface of the housing (100) is referred to as the second point (P2), and the transverse midpoint of the third housing area (130) on the outer surface of the housing (100) is referred to as the third point (P3).

Meanwhile, when viewed from one side in the longitudinal direction, the angle formed by a straight line tangent to the outer surface of the housing (100) facing the ground and the ground is defined as an external angle. In addition, the external angle of each of the first to third housing regions (110, 120, 130) is defined as the angle formed by a tangent line tangent to the outer surface of the housing (100) at each of the first to third points (P1, P2, P3) and the ground when viewed from one side in the longitudinal direction.

In a state where the opening (150) is parallel to the ground, the external angle (not shown) of the third housing area (130) may be different from the external angle (Θ1) of the first housing area (110) and the external angle (Θ2) of the second housing area (120).

For example, as illustrated in FIG. 3a, when the opening (150) is parallel to the ground, the external angle of the third housing area (130) may be configured to be smaller than the external angle (Θ1) of the first housing area (110) and the external angle (Θ2) of the second housing area (120). As a result, at least a portion of the third housing area (130) may be spaced apart from the ground in a settled state.

However, as long as at least a portion of the third housing area (130) can be spaced apart from the ground in a settled state, the relationship between the external angles of the first to third housing areas (110, 120, 130) is not necessarily limited thereto. For example, the external angle of the second housing area (120) may be configured to be smaller than the external angle of the first housing area (110) and the external angle of the third housing area (130). In this case, at least a portion of the third housing area (130) can be spaced apart from the ground in a settled state.

Meanwhile, in FIG. 3a, the tangent line touching the outer surface of the housing (100) at the third point (P3) is shown to be parallel to the ground, so that the outer angle of the third housing area (130) is 0 degrees, but the size of the outer angle of the third housing area (130) is not limited thereto.

Referring to FIGS. 5A and 5B, the opening (150) may not be parallel to the ground in the settled state. For example, the opening (150) may be configured such that one transverse side adjacent to the second shaving aid (19) is closer to the ground than the other transverse side adjacent to the first shaving aid (11).

Through the inclination of this opening (150), the user can easily recognize the rotation direction for using the razor handle (20) coupled to the razor cartridge (10) as a lever. In addition, when the razor handle (20) is coupled to the razor cartridge (10), the opening (150) is inclined to form a predetermined angle with respect to the razor handle (20), so that the coupling between the razor cartridge (10) and the razor handle (20) can be performed more intuitively.

According to one embodiment of the present disclosure, a container (1) for a razor cartridge can have an opening (150) that is naturally inclined when in a seated state due to differences in external angles of the housing (100), etc. Accordingly, since there is no need to separately cut a portion of the housing (100) or add an inclined structure to the housing (100) to create an incline in the opening (150), the overall amount of plastic used during manufacturing can be reduced.

Referring to FIG. 3b, when the opening (150) is viewed from one longitudinal side while being parallel to the ground, the angle (ω1) formed by the straight line connecting the lower end (E1) of the first housing area (110) and the lower end (E2) of the second housing area (120) and the straight line tangent to the opening (150) may be, for example, about 7 degrees to about 13 degrees, preferably about 10 degrees.

In addition, as shown in FIGS. 5a and 5b, the angle (ω2) formed by the straight line contacting the opening (150) with the ground in the settled state may be, for example, about 7 degrees to about 13 degrees, preferably about 10 degrees.

When the aforementioned angles (ω1, ω2) become larger, the user can more easily recognize the rotation direction and the coupling direction of the razor handle (20). However, when the aforementioned angles (ω1, ω2) become excessively large, the amount of plastic required to manufacture the container (1) for the razor cartridge may increase. When the aforementioned angles (ω1, ω2) are about 7 degrees to about 13 degrees, an environmentally friendly razor cartridge container (1) with reduced plastic usage while increasing user convenience can be manufactured.

Referring to FIG. 5a, before the razor cartridge (10) is separated from the housing (100) in a secured state, one transverse side of the opening (150) adjacent to the second shaving aid (19) may be spaced apart from the razor handle (20) coupled to the razor cartridge (10) in a direction perpendicular to the ground by a predetermined distance (L). If one transverse side of the opening (150) adjacent to the second shaving aid (19) and the razor handle (20) coupled to the razor cartridge (10) are not spaced apart in a direction perpendicular to the ground, the rotation of the razor handle (20) may be limited, making it difficult to use it as a lever. The predetermined distance (L) may be proportional to a rotation angle of the razor handle (20) required to separate the razor cartridge (100) from the housing (100) by using the razor handle (20) as a lever, as shown in FIG. 5b.

In addition, as illustrated in FIG. 5b, since the rotation of the razor handle (20) coupled to the razor cartridge (10) may cause the first shaving aid part (11) to interfere with the rear wall (102), the transverse width between the first shaving aid part (11) and the rear wall (102) in the receiving state may be configured to be greater than the transverse width between the second shaving aid part (19) and the front wall (108) in order to smoothly separate the razor cartridge (10). However, it is not necessarily limited thereto.

Although FIGS. 5A and 5B illustrate that the razor cartridge (10) is separated from the housing (100) as the razor handle (20) rotates clockwise, this is not necessarily limited to the present invention. For example, in the state illustrated in FIG. 5A, the razor cartridge (10) may also be separated from the housing (100) as the razor handle (20) rotates counterclockwise.

Meanwhile, referring to FIG. 3c, the angle (φ1) formed by the straight line that touches the first housing area (110) at the first point (P1) and the straight line that touches the third housing area (130) at the third point (P3) may be, for example, about 13.3 degrees to about 24.7 degrees, preferably about 19 degrees. In addition, the angle (φ2) formed by the straight line that touches the second housing area (120) at the second point (P2) and the straight line that touches the third housing area (130) at the third point (P3) may be, for example, about 7 degrees to about 13 degrees, preferably about 10 degrees. The straight line that touches the third housing area (130) at the third point (P3) may be parallel to the opening (150), but is not necessarily limited thereto.

In addition, referring to FIG. 3d, when the direction perpendicular to the opening (150) is referred to as the height direction, the minimum distance (H1) in the height direction between the first housing area (110) and the first shaving aid unit (11) may be smaller than the minimum distance (H2) in the height direction between the second housing area (120) and the second shaving aid unit (19). For example, the minimum distance (H1) in the height direction between the first housing area (110) and the first shaving aid unit (11) may be 0.55 mm to 1.01 mm, preferably about 0.78 mm, and the minimum distance (H2) between the second housing area (120) and the second shaving aid unit (19) may be 2.25 mm to 4.18 mm, preferably about 3.2 mm.

Accordingly, in a case where the razor cartridge (10) is separated from the razor cartridge container (1) by using the razor handle (20) as a lever as shown in FIGS. 5a and 5b, the second shaving aid (19) can be prevented from coming into contact with the second housing area (120) when the razor assembly (30) in which the razor cartridge (10) and the razor handle (20) are combined rotates.

Referring again to FIG. 3d, the minimum distance (H3) in the height direction between the opening (150) and the first shaving aid unit (11) may be greater than the minimum distance (H4) in the height direction between the opening (150) and the second shaving aid unit (19). For example, the minimum distance (H3) between the opening (150) and the first shaving aid unit (11) may be 3.62 mm to 6.72 mm, preferably about 5.17 mm, and the minimum distance (H4) between the opening (150) and the second shaving aid unit (19) may be 0.22 mm to 0.42 mm, preferably about 0.32 mm.

Accordingly, even if the first shaving aid part (11) has a relatively thicker height-wise thickness than the second shaving aid part (19), the first shaving aid part (11) can be stably accommodated between the two components while being spaced apart from the sealing part (200) and the first housing area (110).

In addition, since the minimum distance (H3) between the opening (150) and the first shaving aid (11) is configured to be greater than the minimum distance (H4) between the opening (150) and the second shaving aid (19), the recognition of the lever direction can be increased. For example, the user can check the relationship between the minimum distances (H3, H4) in a state where the sealing part (200) is removed, and through this, can intuitively recognize that the direction of the lever movement is clockwise based on FIG. 3d.

Meanwhile, referring again to FIGS. 1A, 1B, 2 and 3A to 3D, the razor cartridge (10) may further include a pair of cartridge openings (14), a pair of cartridge side holes (16) and a pair of cartridge side walls (17).

A pair of cartridge openings (14) may be configured to penetrate from the upper surface (10_1) of the cartridge to the lower surface (10_2) of the cartridge on both longitudinal sides of the razor cartridge (10). Since rinsing water can pass through the pair of cartridge openings (14), shaving residue and foreign matter present in the razor cartridge (10) can be smoothly discharged.

A pair of cartridge side holes (16) may be formed longitudinally along both longitudinal sides of the razor cartridge (10). At least one shaving blade (15) may be washed by washing water flowing from the outside into the pair of cartridge side holes (16). For example, washing water flowing from the cartridge side hole (16) on one longitudinal side may pass through the at least one shaving blade (15) and then through the cartridge side hole (16) on the other longitudinal side.

A pair of cartridge side holes (16) may be arranged in an area adjacent to a pair of cartridge openings (14), but is not limited thereto. Accordingly, a razor cartridge (10) may include only one configuration of a pair of cartridge openings (14) and a pair of cartridge side holes (16).

A pair of cartridge openings (14) and a pair of cartridge side holes (16) can be in fluid communication with each other. In this case, shaving residue and foreign substances present in the razor cartridge (10) can be discharged more smoothly.

A pair of cartridge side walls (17) can be arranged on both longitudinal sides of the razor cartridge (10). For example, they can be arranged at the bottom of a pair of cartridge side holes (16).

Each of the pair of cartridge side walls (17) may be configured to extend from the cartridge lower surface (10_2) toward the cartridge upper surface (10_1). Accordingly, the pair of cartridge side walls (17) may be formed to have a predetermined height from the cartridge lower surface (10_2). However, they do not necessarily have to extend to have a constant height.

Meanwhile, the razor cartridge (10) may further include a guard (18) and a cap (12). The guard (18) may be positioned in front of at least one shaving blade (15), and the cap (12) may be positioned in the rear of at least one shaving blade (15).

A guard (18) may be positioned between at least one shaving blade (15) and a second shaving aid (19). The guard (18) may stretch the skin before the hair is cut by the at least one shaving blade (15) during shaving, and the user's body hair may be raised in a direction perpendicular to the user's skin surface by the guard (18). This may make it easier to cut the hair by the at least one shaving blade (15).

A cap (12) may be positioned between at least one shaving blade (15) and the first shaving aid (11). The cap (12) may contain a lubricating substance, and thus may serve to protect the user's skin during shaving.

The guard (18) and cap (12) can define a shaving plane (not shown) by providing a support point that comes into contact with the user's skin during shaving.

Below, the internal configurations of the housing (100) for accommodating the aforementioned razor cartridge (10) in the receiving space (155) will be described in detail.

Fig. 6 is a drawing showing only the housing (100) in Fig. 1a cut in the A-A' direction and then viewed from the longitudinal side.

Referring further to FIGS. 1A, 1B, 2 and 3A to 3D in addition to FIG. 6, a housing (100) according to one embodiment of the present disclosure includes all or part of a lower side support portion (160), at least one fixing protrusion (190), a longitudinal side support portion (170) and a side protrusion (180).

The lower support portion (160) may be formed by protruding from one surface adjacent to one longitudinal side of the receiving space (155). For example, the lower support portion (160) may be formed by protruding from the inner surface of each of a pair of longitudinal side walls (104) and may be formed as a pair on both longitudinal sides.

In addition, the lower support member (160) may be positioned at the lower portion in the height direction of each of the pair of longitudinal side walls (104) and may be connected at least in part to the lower wall (106). In this case, the lower support member (160) may protrude in the height direction from the lower wall (106). However, it is not necessarily limited thereto.

In the receiving state, the lower support member (160) may be configured to support one side of the razor cartridge (10) where the cutting edge is exposed, for example, the upper surface (10_1) of the cartridge, from below. Accordingly, the razor cartridge (10) may be prevented from moving toward the lower wall (106) by the lower support member (160) in the receiving state.

The lower support member (160) may be configured such that the height (H6) of one transverse end is greater than the height (H5) of the other transverse end when the opening (150) is parallel to the ground. For example, the lower support member (160) may be configured such that the height (H6) of one transverse end adjacent to the second shaving aid member (19) is greater than the height (H5) of the other transverse end adjacent to the first shaving aid member (11). However, the present invention is not necessarily limited thereto.

In this case, the razor cartridge (10) can be accommodated in the accommodation space (155) so that the opening (150) is parallel to the ground and inclined with respect to the opening (150) in the accommodation state. Accordingly, it can be easier for the user to couple the razor handle (20) to the razor cartridge (10).

For example, when the heights of the transverse ends of the lower support member (160) are the same while the opening (150) is parallel to the ground, the razor cartridge (10) may be parallel to the opening (150) in the seated state and the receiving state, and in this case, the entry angle for the razor handle (20) to engage with the razor cartridge (10) becomes narrower, making engagement more difficult.

Referring again to FIG. 6, when viewed from one longitudinal side, the angle (τ1) formed by the straight line connecting the transverse ends of the lower support member (160) and the straight line tangent to the third housing area (130) at the third point (P3) may be, for example, about 7 degrees to about 13 degrees, preferably about 10 degrees.

At least one fixing projection (190) may be formed to protrude longitudinally from the upper portion of the lower support member (160). At least one fixing projection (190) may be formed to protrude from the inner surface of each of a pair of longitudinal side walls (104) so as to be configured as a pair on both longitudinal sides.

In the receiving state, at least one of the fixing protrusions (190) may be configured to limit movement in a direction toward the opening (150) of the razor cartridge (10). At least a portion of each of the at least one fixing protrusion (190) may be configured to contact the lower surface (10_2) of the razor cartridge (10) in the receiving state.

At least one fixing protrusion (190) may include a plurality of fixing protrusions (190). In this case, when viewed from one longitudinal side, the angle (τ2) formed by the straight line connecting the lower ends of each of the plurality of fixing protrusions (190) at the same point of each of the plurality of fixing protrusions (190), for example, as illustrated in FIG. 6, and the straight line contacting the third housing area (130) at the third point (P3) may be about 6.3 degrees to about 11.7 degrees, preferably about 9 degrees.

Meanwhile, at least one of the fixing protrusions (190) may be a single fixing protrusion, and may be formed as a pair on each of the pair of longitudinal side walls (104). In this case, the lower surface of each fixing protrusion (190) may extend in a certain direction, and the angle formed by a straight line parallel to the extending direction and a straight line contacting the third housing area (130) at the third point (P3) may be about 6.3 degrees to about 11.7 degrees, preferably about 9 degrees.

Accordingly, when the opening (150) is parallel to the ground, the razor cartridge (10) can be maintained in a state of being accommodated in the accommodation space (155) at an angle with respect to the opening (150).

The longitudinal support member (170) may be formed to protrude from the upper surface adjacent to the opening (150) of the lower support member (160) and/or from the inner surface of the longitudinal side wall (104) adjacent to the upper portion of the lower support member (160). When the lower support members (160) are configured as a pair, the longitudinal support members (170) may also be configured as a pair to correspond thereto.

In the receiving state, the longitudinal restraint member (170) may be configured to limit the lateral movement of the razor cartridge (10). For example, as illustrated in FIG. 5A, at least a portion of the longitudinal restraint member (170) may be configured to contact the cartridge side wall portion (17) of the razor cartridge (10) in the receiving state.

When viewed from one side in the longitudinal direction, the shape of the longitudinal prevention support portion (170) may be configured to correspond to the shape of the cartridge side wall portion (17). However, it is not necessarily limited thereto.

The side protrusion (180) can be formed to protrude in the longitudinal direction from one side of the longitudinal prevention support member (170). For example, when the longitudinal prevention support member (170) is configured as a pair, the side protrusion (180) can also be configured as a pair to correspond thereto.

At least a portion of the side protrusion (180) may be positioned within the cartridge side hole (16) in the receiving state, but is not necessarily limited thereto. The side protrusion (180) can prevent foreign substances from entering through the cartridge side hole (16), and the razor cartridge (10) can be more firmly fixed to the housing (100).

In addition, the razor cartridge (10) accommodated in the housing (100) is restricted from longitudinal movement by the longitudinal prevention member (170) and the side protrusion (180). Therefore, when a user attaches the razor handle (20) to the razor cartridge (10) or performs a lever action using the razor handle (20) to detach the razor cartridge (100) from the housing (100), the force is not dispersed in the longitudinal direction, but can be concentrated in the direction for attachment or detachment.

FIGS. 7A to 7C are drawings showing examples of mounting a razor assembly (30) on a container (1) for a razor cartridge according to one embodiment of the present disclosure.

Here, the razor assembly (30) means an assembly in which a razor cartridge (10) and a razor handle (20) are combined.

Referring to FIGS. 7a to 7c, a container (1) for a razor cartridge according to one embodiment of the present disclosure can be utilized as a holder for the razor assembly (30) while the user is using the razor assembly (30) or even after using the razor assembly (30).

For example, in a state where the opening (150) faces the ground as shown in FIG. 7a, the razor assembly (30) is in contact with at least a portion of each of the first housing area (110) and the second housing area (120), so that the razor assembly (30) can be placed on the container (1) for the razor cartridge while forming a predetermined angle with the ground.

Since the first shaving aid part (11) and the second shaving aid part (19) may not touch the ground while the razor assembly (30) is placed in the container (1) for the razor cartridge, the first shaving aid part (11) and the second shaving aid part (19) may be prevented from being contaminated or corroded.

In addition, the container (1) for the razor cartridge is configured so that the first housing area (110) is positioned at a relatively higher position from the ground than the second housing area (120) when the opening (150) faces the ground. In general, the weight of one side of the razor assembly (30) where the razor cartridge (10) is positioned is relatively heavier than the weight of the other side where most of the grip portion (25) is positioned. Therefore, the first housing area (110) is positioned at a higher position from the ground than the second housing area (120) to support one side of the razor assembly (30) that is relatively heavier, thereby allowing the razor assembly (30) to be more stably mounted on the container (1) for the razor cartridge.

Meanwhile, in Fig. 7a, the razor assembly (30) is illustrated as being in contact with both the first housing area (110) and the second housing area (120), but depending on the shape of the razor handle (20), the razor assembly (30) may be configured to only be in contact with the first housing area (110). In this case, the other end of the grip portion (25) of the razor handle (20) may be supported by the ground.

In addition, in a state where the outer surface of the housing (100) faces the wall surface as shown in FIGS. 7b and 7c, the razor assembly (30) is hung on the adhesive portion (140), so that the razor assembly (30) can be placed on the container (1) for the razor cartridge in the longitudinal direction of the razor assembly (30).

For the mounting state of FIGS. 7b and 7c, the housing (100) may include at least one wall attachment portion (700) formed on the outer surface to be attached to a wall.

At least one wall-mounting portion (700) may include an adhesive or the like for attachment to a wall, and the container (1) for the razor cartridge may be maintained in a state of being attached to a wall by the at least one wall-mounting portion (700).

At least one wall attachment portion (700) may be located in the first housing area (110) and/or the second housing area (120).

When at least one wall-mounted portion (700) includes multiple wall-mounted portions (700), each of the multiple wall-mounted portions (700) may be formed at a position corresponding to each of the multiple ground contact portions (500) illustrated in FIGS. 5A and 5B. In this case, each of the multiple wall-mounted portions (700) may be located in each of the first housing area (110) and the second housing area (120).

The adhesion portion (140) may include a rear adhesion portion (720) adjacent to the first housing area (110) and a front adhesion portion (740) adjacent to the second housing area (120).

The razor handle (20) may include a proximal end portion (22), a middle portion (24), and a distal end portion (26). The proximal end portion (22) is the end of the razor handle (20) adjacent to the razor cartridge (10), the distal end portion (26) is the end opposite the proximal end (22), and the middle portion (24) is an area between the proximal end (22) and the distal end (26).

In the case of Fig. 7b, the container (1) for the razor cartridge is attached to the wall with the rear adhesive part (720) positioned on the upper side and the front adhesive part (740) positioned on the lower side.

In this case, the distal end (26) of the razor handle (20) can be supported by the wall surface while the second shaving aid (19) is hung over the rear adhesive portion (720).

However, it is not necessarily limited thereto, and depending on the shape of the razor handle (20), it is also possible for the distal end (26) of the razor handle (20) to be configured so that the middle part (24) is in contact with the front adhesive part (740) while being spaced apart from the wall. In addition, depending on the shape of the razor handle (20) and/or the weight distribution of the razor assembly (30), the distal end (26) and the middle part (24) of the razor handle (20) are not both supported by the container (1) for the razor cartridge, and the razor assembly (30) can be placed on the container (1) for the razor cartridge only in a state where the second shaving aid (19) is hung over the rear adhesive part (720).

When the distal end (26) of the razor handle (20) is supported by a wall surface and/or the middle portion (24) is supported by a front adhesive portion (740), the razor assembly (30) can be more stably mounted on the container (1) for the razor cartridge.

In the case of Fig. 7c, the container (1) for the razor cartridge is attached to the wall with the front adhesive part (740) positioned on the upper side and the rear adhesive part (720) positioned on the lower side.

In this case, the middle part (24) of the razor handle (20) can be supported by the rear adhesive part (720) while the second shaving aid part (19) is hung over the front adhesive part (740). Accordingly, the razor assembly (30) can be more stably placed on the container (1) for the razor cartridge by being supported at two positions spaced apart by the front adhesive part (740) and the rear adhesive part (720).

However, depending on the shape of the razor handle (20) and/or the weight distribution of the razor assembly (30), the razor assembly (30) may be placed on the container (1) for the razor cartridge only in a state where the middle part (24) of the razor handle (20) is not supported by the rear adhesive part (720) and the second shaving aid part (19) is hung on the front adhesive part (740).

The above description is merely an example of the technical idea of the present embodiment, and those skilled in the art will appreciate that various modifications and variations can be made without departing from the essential characteristics of the present embodiment. Therefore, the present embodiments are not intended to limit the technical idea of the present embodiment, but rather to explain it, and the scope of the technical idea of the present embodiment is not limited by these embodiments.
