Description

Liquid vessel {Liquid vessel}

The present invention relates to a container for liquid, and more specifically, to a hygienic container for liquid that prevents leakage of low-viscosity contents other than high-viscosity.

In general, makeup is applied to make the face look bright and beautiful or to prevent skin damage. For such makeup, cosmetics with various colors and textures are used. For example, there are basic products such as lotion and hand cream, and color products such as foundation, lipstick, and mascara. In some cases, cosmetics are delivered to the skin using makeup tools such as brushes (makeup brushes) and puffs.

Containers containing cosmetics come in various sizes and shapes depending on the nature and purpose of the cosmetics. For example, they have a pump structure to discharge the cosmetics through a pumping action, or a tube-type structure that discharges the cosmetics by direct pressure by the user. has

In particular, a tube-type container is made of a cylinder and the contents are stored inside, and a lid is attached to the lower part to open and close, and the upper part is sealed to form a closed structure.

However, for tube-shaped containers that are injection molded with resin, the formulations are limited to various aspects and the discharge diameter is limited to two types (2/5 pi) at the container design stage, and for formulations with low viscosity, the discharge hole diameter is 1.5 mm due to the mold design. It is difficult to mold into smaller sizes and has a structure that is vulnerable to leakage.

When leakage occurs due to this structure, liquid cosmetics remain around the container, and the leaked cosmetics make it difficult to adhere the container and the lid, so the lid is not connected. If the lid is not connected, the amount of leaked liquid further increases, which increases the waste of cosmetics, and there is a risk of deterioration of cosmetics, so improvement is required.

The present invention was created to improve the prior art, and the purpose of the present invention is to provide a container for liquid cosmetics that can prevent liquid cosmetics from leaking.

The objectives, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments taken in conjunction with the accompanying drawings. In this specification, when adding reference numbers to components in each drawing, it should be noted that identical components are given the same number as much as possible even if they are shown in different drawings. Additionally, in explaining the present invention, if it is determined that a detailed description of related known technologies may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

1 to 3 are diagrams for explaining a liquid container according to an embodiment of the present invention, and FIGS. 4 to 5B are diagrams for explaining a discharge portion of a liquid container according to an embodiment of the present invention, 6 to 8 are diagrams for explaining the container portion of a liquid container according to an embodiment of the present invention.

Referring to FIGS. 1 to 8 , a liquid container 100 according to an embodiment of the present invention includes a container portion 110, a discharge portion 120, and a lid 130.

In particular, the liquid container 100 of the present invention may have the structure of an upright tube container with the contents discharged to the bottom, but is not limited to this, and the contents may include liquid cosmetics (basic cosmetics, color cosmetics, cleansing products, etc.) Of course, it can be made up of various contents such as medicines and detergents.

The container unit 110 has an outlet 111A and may be made of a flexible material, such as resin.

And the container portion 110 may include a spout member 111 and a tube 112.

The spout member 111 may be formed with an outlet (111A) so that liquid cosmetics, which are the contents, can be discharged, and may be connected to the discharge portion 120 through which the liquid cosmetics are finally discharged.

The tube 112 may be formed to be thinner than the spout member 111, may be manufactured separately from the spout member 111 and then connected, and may be hollow to accommodate liquid cosmetics.

Here, the container portion 110 may be formed by injection of resin from the first, second, third, and fourth molds (1, 2, 3, and 4). In particular, the spout member 111 is made of an insert injection molding product and is The tube 112 may be connected to the spout member 111 by fusion.

For example, when the spout member 111 is fused to the tube 112, the cross-sectional shape of the fused portion may have a concave groove structure (a stepped structure so that the surfaces facing the spout member 111 and the tube 112 are caught). As the bonding strength of the fusion can be increased by providing the tube 112, various shapes are possible depending on the material of the tube 112 and the fusion process.

In addition, when the container portion 110 is formed by injection, liquid cosmetics are filled, and the tube 112 on the other side of the spout member 111 may be sealed to achieve sealing, but the method of filling is not limited to this. This can be done in a variety of known ways.

And since the injection of the spout member 111 is made to facilitate the coupling of the discharge part 120, it will be described while explaining the discharge part 120.

The discharge part 120 is made of a different material from the container part 110, and does not melt when the container part 110 is injected, but creates a discharge hole 121A (hole for discharging liquid cosmetics) through corrosion treatment or laser cutting. , a material in which a through hole (hole) such as the fixing hole 122A (hole for fixing) can be formed, for example, the material of the discharge portion 120 may be made of a metal material.

In particular, the discharge portion 120 may be made of a metal sheet having a thickness of 0.25 mm to 0.3 mm to enable corrosion treatment and achieve a constant strength, for example, a SUS304 series metal capable of antibacterial action.

And the discharge unit 120 may include a discharge plate 121, a circumferential plate 122, and a drain end (122B).

The discharge plate 121 is formed with a discharge hole 121A, and when the user discharges the liquid cosmetics and uses it, the liquid cosmetics is swept away, so the user's hand can directly contact the discharge plate 121.

At this time, if the discharge hole 121A is formed through a drilling process, the surface of the discharge plate 121 may become rough due to the sheet being pushed by the drill. Therefore, the discharge hole 121A and/or the fixing hole 122A can be processed through corrosion treatment or laser cutting of the discharge portion 120.

That is, the discharge plate 121 is not pushed from one side to the other along the drill, but the metal is simply removed along the shape of the discharge hole 121A, thereby increasing the roughness of the discharge plate 121, which is the area in direct contact with the user's hand. By preventing this, the feeling of use is prevented from deteriorating.

In addition, since the discharge hole (121A) and/or the fixing hole (122A) are formed by inkjet corrosion treatment or laser cutting, the diameter of the hole can be made finer than that of a drill due to the corrosion treatment method, resulting in a discharge hole of 0.3 mm. (121A) may be formed.

Therefore, while the existing discharge hole is formed to be about 1.5 mm, forming a structure in which the liquid cosmetics leaks due to its own weight, the diameter of the discharge hole (121A) in this embodiment can be designed to fall within the range of the surface tension of the liquid cosmetics, thereby preventing the liquid cosmetics from leaking. This can be prevented.

In addition, the discharge hole (121A) can be formed using corrosion treatment or laser cutting, so the design of the arrangement and number of discharge holes (121A) can be freely designed, so discharge is performed along the outline of an image reminiscent of a character, brand mark, etc. Since the hole 121A can be formed, it is possible to improve aesthetics and upgrade the product.

In this way, the discharge hole 121A may be formed as a plurality of holes along the outer edge of the image so as to represent a shape such as a character or brand mark.

However, as the discharge hole 121A on the discharge plate 121 moves away from the center to the outside during the press processing process, shape deformation may increase. Therefore, so that the arrangement of the discharge hole 121A reminiscent of the image does not deviate from the design, and the discharge plate 121 is wide enough, the diameter/length of the discharge plate 121 is equal to the length of the circumferential plate 122. It is desirable to make it at least the same or larger. That is, the area of the discharge plate 121 may be large enough for the discharge hole 121A to be provided inside the discharge plate 121.

However, if an image is not evoked through the arrangement of the discharge hole (121A), or if the arrangement of the discharge hole (121A) is changed, the length/diameter of the discharge plate 121 will be smaller than the length of the circumferential plate 122. It may be possible.

Alternatively, regardless of the length of the circumferential plate 122, the area of the circumferential plate 122 is sufficiently large, that is, the shape of the discharge hole 121A is minimal during processing, etc. Various variations are possible, such as the length may be made independent of the length of the circumferential plate 122.

The circumferential plate 122 extends from the discharge plate 121, covers at least a portion of the container portion 110, and has a fixing hole 122A in the area of the circumferential plate 122 covered by the container portion 110. It can be provided.

Here, as referring to a in FIG. 4, the discharge unit 120 is a sheet (plate), such as a circle, through a process such as pressing, as shown in b in FIG. 4, to the discharge plate 121. In contrast, the peripheral plate 122 may be bent/bent.

In addition, a plurality of fixing holes 122A formed in the circumferential plate 122 may be provided along the circumferential surface of the circumferential plate 122. Additionally, the fixing hole 122A may be formed in various shapes depending on the flowability of the resin material of the container portion 110 and the shape of the injection port of the injection molding machine.

That is, the fixing hole 122A may be formed in various forms, such as a long hole extending in the same direction as the flow direction of the liquid cosmetics discharged from the container unit 110, extending in an inclined direction, or extending in a right angle direction.

However, for convenience of understanding, the longitudinal direction of the fixing hole (122A) is described in terms of the flow direction of liquid cosmetics. However, the fixing hole (122A) is a configuration in which the container portion 110 interferes, and specifically, the resin The hole for injection is preferably made according to the arrangement of the injection port of the injection molding machine.

For example, referring to FIG. 5A, the resin to form the container portion 110 may be injected from the drain end 122B toward the discharge plate 121. At this time, when the flowability of the resin is good and the resin flows easily, the resin can flow to a location spaced apart from the drain end (122B), so the shape of the fixing hole (122A) is a long hole extending at a right angle from the drain end (122B). can be achieved.

On the other hand, referring to 5b, when the flowability is poor, such as a slow flow of resin, the fixing hole 122A is formed as a long hole adjacent to the drain end 122B and in the horizontal direction with respect to the drain end 122B. can be prepared.

Of course, the shape of the fixing hole (122A) may be not only a hole with a curved surface, but also various shapes such as square and right angle, and the length of the narrowest width of the fixing hole (122A) may be 1 mm, but it is not limited to this, and the shape of the fixing hole (122A) is not limited to this. The spacing of the fixing holes 122A may also vary.

The drain end 122B may protrude along the outer peripheral surface of the peripheral plate 122. The drain end 122B may be rolled outward along the outer circumferential surface of the circumferential plate 122 during the processing of the discharge portion 120, or may be formed in a form whose thickness is expanded.

This drain end (122B) may be removed through a post-processing process such as cutting, but the drain end (122B) may be left to omit post-processing, so that the drain end (122B) may be left when the container portion 110 is injected. The formed discharge portion 120 can be used as is.

That is, the drain end 122B of the discharge unit 120 may remain embedded in the container part 110, forming a structure in which the container part 110 and the drain end 122B interfere with each other, thereby forming a bonding force. This may be improved.

Meanwhile, even if the drain end (122B) is omitted, the connection is made through the fixing hole (122A), so the overall size of the discharge portion 120 can be reduced by cutting the drain end (122B), so that the liquid container 100 The overall size can also be compacted.

And the injection of the container part 110 integrated with the discharge part 120 is as follows.

Referring to FIGS. 6 to 8 , as shown in FIG. 6 , the discharge portion 120 has an outlet 111A of the container portion 110 formed in the first mold 1 when the container portion 110 is injected. placed in a position to be Then, the second mold 2 is placed inside the discharge port 111A.

Then, as shown in FIG. 7, the third mold 3 and the fourth mold 4 are placed outside the discharge port 111A. At this time, a gap (not shown) for forming the container portion 110 is formed between the second mold 2, the third mold 3, and the fourth mold 4.

Then, as shown in FIG. 8, resin is injected into the gap so that the container portion 110 can be injected. Here, with the discharge portion 120 disposed at the discharge port 111A, the resin forming the container portion 110 surrounds the discharge portion 120 and a casting is formed, so that the discharge portion 120 and the container portion ( 110) can be connected without a separate assembly process.

In addition, a fixing hole 122A for resin injection is provided on the peripheral surface of the discharge unit 120 facing the container unit 110, and during the injection process, the container unit 110 is attached to the inner peripheral surface of the discharge unit 120. and surround the outer peripheral surface, and can be connected to each other from the inner and outer areas of the discharge unit 120 through the fixing hole 122A, thereby preventing the discharge unit 120 from being separated from the container unit 110.

Meanwhile, the container unit 110 may be provided to surround only one of the inner or outer peripheral surfaces of the discharge unit 120, and in this case, the resin is injected into the fixing hole 122A from the inner or outer peripheral surface of the discharge unit 120. Thus, the discharge unit 120 and the container unit 110 may be connected to each other.

That is, in order to ensure a firm connection, it is desirable for the resin of the container unit 110 to be formed from the inner and outer areas of the discharge unit 120 to the fixing hole 122A. However, this is not limited to this and various modifications can be made.

In addition, the resin of the container portion 110 can be easily cooled because it is formed in the fixing hole 122A made of metal and comes into contact with the metal, which is advantageous for deformation when taking out and can increase appearance quality and productivity.

In addition, it goes without saying that the container unit 110 can be stored regardless of the state, such as upright, inverted, or lying down.

The lid 130 covers the container portion 110, and may be separated from or combined with the container portion 110 depending on whether liquid cosmetics are used.

For example, the structure of the lid 130 coupled to the container unit 110 may be formed by combining threads (not shown) or undercuts (closed curved rings, etc.). Alternatively, the lid 130 may be provided with a flip-type cover to open and close, and various known structures may be applied, so detailed description will be omitted.

However, the lid 130 of this embodiment may include a plug 131 and packing 132.

The plug 131 may protrude so that at least a portion of the discharge unit 120 is inserted and may be in close contact with the peripheral surface of the discharge unit 120 .

Of course, the plug 131 is discharged as if it surrounds the spout member 111 instead of surrounding the discharge part 120, or the plug 131 forms a stage and surrounds both the discharge part 120 and the spout member 111. Various structures for sealing the unit 120 are possible.

Packing 132 may be provided inside the plug 131 to seal the discharge hole 121A. For example, the packing 132 may be made of foam or an elastic material such as rubber or silicon and may be in close contact with the discharge hole 121A, but the material is not limited.

In this way, since it is primarily covered through the combination of the lid 130, secondarily sealed through the plug 131, and sealed again through the packing 132, the sealed structure of the container portion 110 is It can be improved.

In this way, in this embodiment, the liquid cosmetics do not leak, thereby preventing product waste, and the bonding force due to leakage does not decrease, so the lid 130 can be smoothly coupled, preventing contact with air, thereby preventing deterioration of the product. can do.

Although the present invention has been described in detail through specific examples, this is for the purpose of explaining the present invention in detail, and the present invention is not limited thereto, and can be used by those skilled in the art within the technical idea of the present invention. It would be clear that modifications and improvements are possible.

Any simple modification or change of the present invention falls within the scope of the present invention, and the specific scope of protection of the present invention will be clarified by the attached utility model claims.
