Description

Description

Title of the invention: Assembly comprising a container and a lid intended to close the container

Technical area

The present invention relates to an assembly comprising a container and a lid intended to close a container.

Prior technique

[0002] Lids intended to close containers are known from the prior art. Lids generally include a cover portion configured to cover an opening of the container when the lid is mounted on the container and an attachment portion configured to allow the lid to attach to the container when the lid is mounted on the container.

[0003] For example, the fixing part may comprise a U-shaped skirt extending over the periphery of the cover part, the skirt comprising a first wall proximal to the cover part, a second wall distal to the covering and a third wall which connects the first wall and the second wall so as to form a housing intended to receive a complementary fixing part of the container, the connecting wall forming the bottom of the housing.

[0004] To minimize the risk of leakage of product contained in the container when the container is closed by the lid, the fixing of the lid on the container is sealed.

[0005] As such, it is known to have a seal in the fixing part of the lid.

The seal is generally arranged in the bottom of the housing, that is to say, it extends over the entire third wall which connects the first wall and the second wall. When mounting the cover on the container, the complementary fixing part of the container engages in the remaining space of the housing in which the seal is arranged.

The complementary fixing part of the container then comes into contact with the seal arranged in the bottom of the housing.

The seal is located between the bottom of the housing (formed by the third wall) and the complementary fixing part of the container.

[0010] A compressive force must be applied to the lid in order to be able to close the lid on the container.

[0011] A disadvantage of the covers of the prior art is that it is necessary to apply a significant or even excessive compression force on the cover in order to be able to compress the seal and thus succeed in closing the fastening part of the cover. on the complementary fixing part of the container.

The provision of the seal which is located between the bottom of the housing of the lid fixing device and the complementary fixing device of the container can be an obstacle to a simple and quick closure for a user.

[0013] Document WO 2021/159288 describes a lid intended to close a cup configured to contain a few centiliters of tea or coffee, for example.

Description of embodiments

Other characteristics and advantages of the invention will appear on reading the non-limiting description which follows and the appended figures which schematically illustrate several embodiments of the lid according to the invention and of the assembly comprising the cover and a container according to the invention.

In the following description and in the claims, identical, similar or analogous components will be designated by the same reference numerals in order to facilitate the description.

Figure 1 illustrates an assembly 1 comprising a cover 2 mounted on a container 4 according to this presentation. The cover 2 comprises a covering part 6 configured to cover an opening 8 of the container 4 (figure 3) and a fixing part 10 configured to allow the cover 2 to be fixed on the container 4.

The fixing part 10 extends over the periphery of the covering part 6.

In this presentation, the cover part 6 is arranged below the fixing part 10 (Figure 3).

The fixing part 10 thus forms a rim around the cover part 6. This makes it possible to be able to stack a plurality of containers 1′ closed by lids according to the invention on top of each other in a compact manner (figures 3 ).

In the present description, the cover part 6 and the fixing part 10 are in one piece.

As illustrated in Figures 2 to 6, the fixing part 10 of the cover 2 according to the present disclosure comprises a U-shaped skirt 12 which extends over the periphery of the covering part 6.

The peripheral skirt 12 comprises a first wall 14 proximal to the cover part 6, a second wall 16 distal to the cover part 6 and a third wall 18 which connects the first wall 14 and the second wall 16.

According to this presentation, the first wall 14, the second wall 16 and the third wall 18 are formed in one piece.

The first wall 14, proximal to the cover part 6, can extend, for example in its entirety, parallel to the axis "X" passing through the center of the cover 2 (FIGS. 9 and 10). By the axis "X" passing through the center of the cover 2, is meant the axis of revolution of the cover 2.

[0065] For example, the first wall 14 extends vertically, for example in its entirety, with reference to Figures 2 to 9 and 12, which illustrate the first wall 14 when the cover 2 is mounted on the container 4 and the container 4 is placed, for example vertically on a floor.

[0066] For example, the first wall 14 extends so as to form part of the lid

2 of cylindrical shape (Figure 10). The first wall 14, the second wall 16 and the third wall 18 are arranged so as to form the peripheral skirt 12 in the shape of a U.

It is understood that the first wall 14 and the second wall 16 are side walls arranged facing each other and that the third wall 18 which has two substantially curved end portions is intended to connect the first side wall 14 and the second side wall 16.

The first wall 14, the second wall 16 and the third wall 18 thus form a housing 20 intended to receive a complementary fixing part 22 of the container 4. The third wall 18 forms a bottom of the housing (figures 3 to 6) .

[0070] According to the present description, the housing 20 comprises a first zone 20′ extending between the first wall 14 and the middle of the third wall 18 and a second zone 20″ extending between the middle of the third wall 18 and the second wall 16.

It is understood that the first zone 20' is defined between the first wall 14 and the middle of the third wall 18 and that the second zone 20" is defined between the middle of the third wall 18 and the second wall 16.

In other words, the housing comprises two zones delimited from each other by the middle of the third wall. It is then understood that the U-shaped peripheral skirt is divided into two parts that are substantially symmetrical relative to each other so as to form a housing comprising two zones.

[0073] According to this presentation, the cover 2 comprises a seal 24.

The seal 24 is arranged in at least a portion of the first zone 20' of the housing 20 only.

[0075] It is understood that the seal extends over all or part of the first zone only. The seal is arranged in the first zone of the housing only.

The seal 24 can be a seal which extends over the periphery of the cover 2.

In the present presentation, the cover is circular. The seal is a peripheral annular seal. The invention is not limited to a circular lid and any type of lid can be used: square, rectangular, etc.

According to one embodiment illustrated in Figures 2 to 6, the seal 24 extends over at least part of the first wall 14 and over half of the third wall 18.

[0080] For example, the seal 24 extends over only part of the first wall 14.

According to the present presentation, the seal 24 extends parallel to the first wall 14. It is then understood that the seal 24 extends vertically relative to the bottom of the housing 18 defined by the third wall .

According to this presentation, the seal 24 comprises a substantially flat outer surface 240 (Figure 4).

[0083] For example, the seal 24 has a rectangular section in cross section.

[0084] According to one embodiment, the seal 24 comprises a first end 24′ arranged facing the third wall 18 and a second end 24″ opposite the first end 24′, the second end 24″ comprising a rounded surface configured to guide the complementary fixing part 22 of the container 4 in the second zone 20" of the housing 20 when the lid is mounted on the container (FIG. 4).

According to one embodiment, the first end 24' of the seal 24 is curved so as to adapt to the shape of the bottom of the housing 18 of the cover 2 when the seal extends over the half of the third wall. This allows the seal to be able to fit optimally in the housing of the cover.

According to one embodiment illustrated in Figure 2, the third wall 18 may comprise a rib 26 arranged in the middle of the third wall, that is to say in the middle of the bottom of the housing, the rib 26 is extending into the housing 20. The rib 26 makes it possible to further delimit the first zone 20' and the second zone 20" and to maintain the seal 24 in the first zone 20' of the housing 20. [0087] According to this presentation, the cover 2 comprises a plastic material and the seal 24 comprises an elastomeric material.

[0088] It is understood that the cover comprises a hard material and that the seal comprises a flexible material.

For example, the plastic material of cover 2 is high density polyethylene (HDPE) or polypropylene. The invention is not limited to these types of plastic materials. Other plastic materials can be used.

[0090] According to this presentation, the seal 24 is overmolded with the cover 2.

[0091] Figure 3 is an enlarged view of the assembly 1 comprising the lid 2 and the container 4 illustrated in Figure 1.

As illustrated in Figure 3, the assembly 1 comprises the lid as previously described and the container 4. The container 4 comprises a body 28, the body 28 of the container having a lower end 30 closed (Figure 1) and an upper end portion 32 comprising the opening 8, and the fixing part 22 complementary to the fixing part 10 of the cover 2.

[0093] According to the present description, the complementary fixing part 22 is intended to engage in at least one free part of the housing 20 of the fixing part 10 of the cover 2 .

The term “free part of the housing” means the part of the housing delimited by the seal and the second wall distal to the covering part. According to an embodiment illustrated in FIGS. 3 to 6, the complementary fixing part 22 comprises a first portion 22′, one end of which is intended to come into direct contact with one half of the bottom of the housing in the second zone 20″, it that is to say half of the third wall For example the first portion 22' can be a peripheral wall.

According to the present description, the complementary fixing part 22 can comprise a second portion 22". The second portion 22" can for example be a U-shaped peripheral skirt from which the first portion extends.

For example, the skirt 260 is an annular skirt. For example the skirt 260 has an inverted U shape. The skirt 260 (FIG. 9) may comprise a first wall 262 proximal to a central part of the container, for example proximal to the "X'" axis passing through the center of the container (FIG. 11), a second wall 264 distal to a central part of the container, for example distal to the "X" axis passing through the center of the container, and a third wall 266 which connects the first wall 262 and the second wall 264.

As illustrated in Figure 9, the peripheral wall 270 forming the first portion 22' of the complementary fixing part 22 can extend from the third wall 266 of the skirt 260 forming the second portion 22'' of the complementary fixing part 22. The peripheral wall 270 extends for example perpendicular to the third wall 266 of the skirt 260.

The first wall 262, the second wall 264 and the third wall 266 are arranged so as to form the U-shaped annular skirt 260 of the container 4.

It is understood that the first wall 262 and the second wall 264 are side walls arranged facing each other and that the third wall 266, which has for example two substantially curved end portions, is intended connecting the first side wall 262 and the second side wall 264.

According to the present description, the first wall 262, the second wall 264 and the third wall 266 are formed in one piece.

The first wall 262 can extend, for example in its entirety, parallel to the axis "X'" passing through the center of the container 4 (FIGS. 9 and 11). By the axis "X'" passing through the center of the container 4, is meant the axis of revolution of the container 4.

For example, the first wall 262 extends, for example in its entirety, vertically with reference to Figures 3 to 9 and 12 which illustrate the first wall 262 when the container is placed, for example vertically on a floor.

As illustrated in Figure 12, the axis of revolution "X" of the lid 2 and the axis of revolution "X'" of the container 4 coincide when the lid 2 is mounted on the container 4. [0105] The second portion of the complementary fastening part of the container comprises an end 222 intended to engage against the rounded end 24" of the seal 24 of the lid. The rounded end 24" of the seal 24 makes it possible to stabilize the fixing of the fixing part 22 complementary to the container 4 in the housing 20 of the lid. The end of the second portion comprises a shape complementary to the rounded end of the seal.

[0106] For example, the end 222 intended to engage against the rounded end 24" of the seal 24 of the cover is one of the two end portions, for example substantially curved, of the third wall 266 forming the skirt 260 of the container.

[0107] When the cover 2 is mounted on the container 4, sealing is ensured between the complementary fixing part 22 of the container and the substantially planar outer surface 240 of the seal intended to come into contact with the fixing part complementary 22.

[0108] When the second end 24" of the seal 24 is rounded and is in contact and fitted with the end 222 of the complementary fixing part of the container 4, sealing is also ensured between said second end 24" rounded and the end 222 of the complementary fixing part of the container 4. The seal is thus reinforced.

In the present description, the body 28 of the container 4 may comprise a first body part 280 having an increasing section, for example from the lower end portion 30 towards the upper end portion 32.

The first part 280 of the body 28 can thus have a frustoconical shape (FIGS. 11 and 12).

The body 28 of the container 4, for example the upper end portion 32 of the container 4, may comprise a second part 282 of the body of cylindrical shape.

For example, the first wall 262 of the skirt 260 of the container 4 can form the second part 282 of the body of the container which is cylindrical. The second part 282 of the body of the container, of cylindrical shape, extends for example in the extension of the first part 280 of the body of the container 28, of frustoconical shape. As illustrated in Figure 3, the complementary fixing part 22 of the container can comprise a peripheral heel 34 comprising an upper face and a lower face, and the second wall 16 of the fixing part of the lid can comprise a rib peripheral 36 extending into the housing so as to engage against the underside of the peripheral heel 34 of the complementary fastening part of the container.

For example, the peripheral heel 34 is arranged on the first portion 22' of the fixing part 22 complementary to the container 4.

For example, the peripheral heel 34 is arranged on the peripheral annular wall 270 forming the first portion 22' of the fixing part 22 complementary to the container 4.

[0116] This makes it possible to provide a fixing of the lid on the container by snap-fastening.

[0117] According to the present disclosure, the cover 2 as previously described is manufactured by a manufacturing process comprising a step in which a cover 2 as previously described is provided and in which the seal 24 is arranged in at least part of the first housing area only.

[0118]According to one characteristic, the method comprises a step in which the seal is molded onto the cover by injection.

In operation, as shown in Figures 4 to 6, the cover 2 is mounted on the container 4. During assembly, the fixing device 22 complementary to the container 4 engages in the housing 20 of the cover 2 and comes into contact with the rounded end 24'' of the gasket 24 which is arranged in the first zone 20' of the housing 20 of the lid 2. The rounded end 24'' of the gasket 24 guides the insertion of the complementary fixing device 22 of the container 4 in the second zone 20" of the housing 20 of the cover 2 (FIG. 4).

[0120] The complementary fastening device 22 engages in the second zone 20" of the housing 20 of the cover 2, along the seal 24. The first portion 22' of the complementary fixing device 22 of the receptacle comes into direct contact with half of the bottom of the housing 18, that is to say half of the third wall 18 of the second zone 20" of the housing 20 of the lid.

[0122] The fact that the seal is not arranged between the bottom of the housing 18 (that is to say on the entire third wall) and the complementary fixing device 22 of the container during assembly , it is not necessary to apply an excessive compressive force to the cover 2 so that it can be fixed on the container 4.

The seal 24 is located next to the complementary fixing device 22 of the container.

During assembly, the peripheral rib 36 of the second wall 16 of the fixing part of the cover engages against the underside of the peripheral heel 34 of the complementary fixing part of the container.

The cover 2 is thus mounted on the container 4 by snap-fastening.

[0126] Once the cover 2 has been mounted on the container 4, the seal 24 which was slightly compressed by the complementary fixing device 22 when it is engaged in the housing 20 of the cover 2 can expand between the first wall 24 and the complementary fastening device 22 so as to provide a tight seal between the cover 2 and the container 4 (FIG. 6).

[0127] As illustrated in Figure 5, the second portion 22 'of the complementary fixing device 22 of the container can engage in the rounded end 24' of the seal 24 of the lid, which makes it possible to further improve the seal between the lid and the container.

In one embodiment illustrated in Figure 7, the complementary fixing part 22 of the container may comprise a second peripheral heel 40 comprising an upper face 41 and a lower face 42, and the second wall 16 of the fixing part of the cover may comprise a second peripheral rib 43 extending into the housing so as to engage against the underside 42 of the second peripheral heel 40 of the complementary fastening part of the container. In the present description, the second peripheral heel 40 is arranged under the first peripheral heel and the second peripheral rib 43 is arranged under the first peripheral rib 36.

[0130] For example, the second peripheral heel 40 is arranged on the second portion 22” of the fixing part 22 complementary to the container 4.

This makes it possible to further reinforce the fixing of the cover to the container by snap-fastening.

In one embodiment illustrated in Figure 8, the complementary fixing part 22 of the container may comprise a third peripheral heel 50 comprising an upper face 51 and a lower face 52, and the second wall 16 of the fixing part of the cover may comprise a third peripheral rib 53 extending into the housing so as to engage against the underside 52 of the second peripheral heel 50 of the complementary fastening part of the container.

In the present description, the third peripheral heel 50 is arranged under the second peripheral heel 40 and the third peripheral rib 53 is arranged under the second peripheral rib 43.

For example, the third peripheral heel 50 is arranged on the second portion 22” of the fixing part 22 complementary to the container 4.

This makes it possible to further reinforce the fixing of the cover to the container by snap-fastening.

[0136] Thanks to the plurality of heels of the container and to the complementary ribs of the lid, the holding of the lid on the container is improved and reinforced.

As an alternative to the plurality of heels of the container 4 and to the complementary ribs of the cover 2 previously described which allow the cover 2 to be fixed to the container by clipping, the cover 2 can be fixed to the container 4 by screwing.

The cover 2 and the container 4 are configured so as to allow the cover 2 to be fixed to the container 4 by screwing.

[0139] Figure 13 illustrates the lid 2 when it is screwed to the container 4. As illustrated in Figures 14 and 15, the lid 2 may include a thread 64 configured to cooperate with a complementary thread 60 of the container 4.

[0141] For example, in the assembly illustrated in Figure 13, the second wall 16 of the fixing part 10 of the cover 2 can comprise the thread 64, for example annular and the complementary fixing part 22 of the container 4 can comprise the complementary thread 60, for example annular.

For example, the complementary thread 60 is arranged on the peripheral annular wall 270 forming the first portion 22' of the fixing part 22 complementary to the container 4 (FIG. 14).

As illustrated in Figure 9, assembly 1 as previously described may further comprise a deformation rib 7 configured to deform part of seal 24 when lid 2 is mounted on container 8.

[0144] The assembly 1 may comprise the cover 2 as previously described, the container 4 as previously described and the deformation rib 7 configured to deform part of the seal 24 when the cover 2 is mounted on the container. 4.

In the example illustrated in Figure 9, the complementary fixing part 22 of the container comprises for example two peripheral heels 34, 40 and the second wall 16 of the fixing part 10 of the lid comprises for example two ribs peripherals 36, 43.

For example, the deformation rib 7 is configured to deform at least part of the seal 24, for example part of the seal 24, for example only part of the seal 24.

The seal 24 is configured to be elastically deformed by the deformation rib 7.

[0148] The deformation rib 7 is configured to maintain the deformed part of the seal as long as the cover 2 is mounted on the container 4. For example, the deformation rib 7 is configured to deform the part of the seal 24 when the deformation rib 7 comes into contact, for example directly, with the seal 24.

For example, the deformation is reversible.

For example, the part of the deformed seal 24 is configured to return to its initial shape, for example when the deformation rib 7 is no longer in contact with the seal 24, for example when the cover 2 is disassembled, for example removed from the container 4.

For example, the deformation rib 7 is configured to deform only part of the seal 24 when the lid 2 is mounted on the container 4.

[0153] For example, the deformation rib 7 is configured to deform an edge of the seal 24.

For example, the deformation rib 7 is configured to deform the second end 24'' of the seal, comprising for example a rounded surface.

For example, the seal 24 is configured to be deformed by shape complementarity with the deformation rib 7.

For example, the deformation rib 7 may have a “V” shape, for example a “V” shaped section.

[0157] For example, the deformation rib 7 is configured so as to deform the part of the seal 24 so that the part of the seal, deformed, forms a "V" whose two legs extend on either side of the deformation rib 7 when the cover 2 is mounted on the container 4.

For example, the part of the seal 24 is configured to perform an expansion on either side of the deformation rib 7, for example when the deformation rib 7 is in contact with the seal 24 and deforms the part of the seal, for example when the lid 2 is mounted on the container 4.

For example, container 4 includes deformation rib 7. [0160] For example, the complementary fixing part 22 comprises the deformation rib 7.

[0161] For example, the second portion 22” of the complementary fixing part 22 comprises the deformation rib 7.

[0162] For example, the deformation rib 7 can be arranged on the end 222 of the second portion 22” of the complementary fixing part 22, intended to engage against the second end 24” of the seal 24 when the lid 2 is mounted on the container 4.

For example, the deformation rib 7 can be arranged on the skirt 260 of the container.

[0164] For example, the deformation rib 7 can extend along the skirt 260 of the container 4.

The deformation rib 7 can be an annular rib.

For example, the deformation rib 7 can be arranged on the third wall 266 of the annular skirt 260 of the container 4.

For example, the deformation rib 7 projects from the annular skirt 260 of the container 4.

For example, the deformation rib 7 projects from the third wall 266 of the annular skirt 260 of the container 4.

For example, the deformation rib 7 is formed in one piece with the container 4.

For example, the deformation rib 7 is formed in one piece with the annular skirt 260 of the container 4.

When the lid 2 is mounted on the container 4, sealing is ensured between the complementary fixing part 22 of the container and the substantially planar outer surface 240 of the seal intended to come into contact with the fixing part. complementary 22. When the second end 24" of the seal 24 is rounded and is in contact with the end 222 of the complementary fixing part of the container 4, sealing is also ensured between said second end 24" rounded and the end 222 of the complementary fixing part of the container 4. The seal is thus reinforced.

[0173] The tightness is all the more reinforced by the presence of the deformation rib 7, arranged for example on the end 222 of the complementary fixing part of the container 4 intended to engage against the rounded end 24 " of the seal 24.

The deformation rib 7 makes it possible to deform the seal 24 so that the seal 24 is expanded and widens, for example punctually, for example locally, so as to improve the contact and enlarge the contact surface between the seal 24 and the container 4.

This configuration makes it possible to ensure optimal sealing over a maximum contact surface between the lid and the container.

When the first wall 14 of the skirt 12 of the cover 2 extends, for example in its entirety, parallel to the axis "X" passing through the center of the cover (FIGS. 9 and 10) and the first wall 262 of the skirt 260 of the container 4 extends, for example in its entirety, parallel to the axis "X'" passing through the center of the container (FIGS. 9 and 11), the contact surface between these two walls 14, 262 (Figure 9) is extended and makes it possible to reinforce the mechanical strength of the cover 2 on the container 4, for example by the plastic-plastic contact between the two walls 14, 262, when the cover 2 is mounted on the container 4.

This configuration also makes it possible to improve the attachment of the lid 2 to the container 4, for example by means of the heels of the lid 2 and to the ribs of the container 4.

When the assembly 1 has the arrangement of the walls 14, 262 of the lid and of the container as previously described, that is to say extending parallel to the respective axes of revolution of the lid and of the container and that the set includes the deformation rib 7, this configuration ensures both mechanical strength of the cover on the container and optimal sealing.

Obviously, the invention is not limited to the examples which have just been described and many adjustments can be made to these examples without departing from the scope of the invention. In particular, the different characteristics, forms, variants and embodiments of the invention can be associated with each other in various combinations insofar as they are not incompatible or exclusive of each other.
