Description

DESCRIPTION

TITLE: WATERPROOF LID FOR CONTAINER, AND CONTAINER COMPRISING A CONTAINER AND A WATERPROOF LID

The present invention relates to the technical field of containers comprising a container and a lid.

The present invention relates more particularly to a sealed lid intended to be used with a container.

The present invention relates in particular, but not exclusively, to reusable containers designed to receive food preparations, such as for example yoghurts.

Documents WO2011/144869 and WO2011/144870 disclose a container whose side wall has an outer bead in its upper part. This outer bead forms an extra thickness having a lower annular rim provided for suspending the container in an opening of appropriate section. This outer bead has a slight slope, the container having an outer perimeter decreasing towards the base of the outer bead. This outer bead serves as a support wall for a lower peripheral collar of a cover configured to close the upper opening of the container. Such a container can be made of glass. A disadvantage of the aforementioned embodiment lies in the dimensional tolerances of the container which thwarts obtaining a satisfactory seal when the container is sealed with the aforementioned lid.

Document CN 204184715 U discloses a container comprising a lid hingedly mounted on a container with a hinge device comprising an upper element enclosing the lid and a lower element enclosing the container. The lower element and the upper element are mounted in grooves and are hinged relative to each other. A removable retaining device connecting the upper element to the lower element is arranged opposite the articulation. A drawback of the aforementioned embodiment resides in the manipulations necessary to close the lid on the container. The lid retainer has several moving parts which must be handled precisely to ensure tight closure of the lid. Another drawback of the aforementioned embodiment resides in the manipulations necessary to separate the lid and the container. It is in fact necessary to disassemble the hinge device in order to be able to dissociate the lid from the container.

An object of the present invention is to provide a leak-proof lid intended for use with a container having a lower annular rim, which is easier to remove and put in place.

Another object of the present invention is to provide a container comprising a tight lid and a receptacle having a lower annular rim, in which the tight lid is easier to remove and put in place.

These objects are achieved with a leaktight lid configured to be used with a container comprising an upper edge and a side wall having a lower annular rim, the leaktight lid comprising a closure piece carrying an annular support element configured to bear annular manner on the upper edge, and a hooking member connected to the closure piece by a first elastic hinge, due to the fact that the sealed lid comprises a ring configured to be mounted around the container to come to rest under the annular rim lower, and that the hooking member is configured to come into engagement with the ring so that the annular support element seals with the upper edge when the ring bears under the lower annular rim and that the attachment member is in engagement with the ring. Thus the hooking member of the sealed lid according to the invention comes into engagement with a part of the sealed lid, and not with the container. Such an embodiment makes it possible to better overcome the dimensional tolerances of the container, in particular when the container is made of glass. Such an embodiment also makes it possible to better guarantee the attachment of the sealed cover. If desired, several first elastic hinges can be provided between the attachment member and the closure part. The first elastic hinge, the hooking member and at least a part of the closure part can belong to a body made of plastic material. The body can in particular be made of injected plastic material. If desired, the body can be made of transparent or translucent material. Alternatively, the closure piece may include an insert. The body can then be molded onto the closure part.

The annular support element may be formed by an annular seal configured to bear against the upper edge when the ring bears under the lower annular rim and the attachment member is in engagement with the ring. Alternatively, the annular support element may in particular come from the body, and for example be formed by an annular lip engaged inside or outside the upper edge of the container.

The body may have a peripheral lower annular rib, the annular seal being mounted under the body inside the peripheral lower annular rib.

The body may have an inner lower annular rib, the annular seal being mounted under the body between the peripheral lower annular rib and the inner lower annular rib.

Alternatively, the annular gasket can in particular be molded onto the body.

The hooking member may have a hook configured to engage a lower edge of the ring when the hooking member is engaged with the ring.

The hook can then be engaged in a lower housing of the ring adjacent to the lower edge when the attachment member is in engagement with the ring. This arrangement makes it possible to reinforce the ring.

The attachment member can then have a second hook configured to come into engagement with a lower rib of the body when the attachment member is engaged with the ring. This arrangement makes it possible to improve the tightness of the container formed by the tight lid closing the container.

According to one embodiment, the sealed cover may include a second elastic hinge connecting the closure part to the ring. The second elastic hinge and the ring can belong to the body.

The first elastic hinge can be arranged opposite the second elastic hinge with respect to the closure part.

The ring can have four sides, the second elastic hinge being connected to a first side.

The attachment member can then be configured to come into engagement with a second side opposite the first side.

The second elastic hinge may comprise a first elastic part connected to a second elastic part by an intermediate part which is more rigid than the first elastic part and than the second elastic part. This arrangement makes it possible to provide the first elastic part at the level of the upper edge of the container and to provide the second elastic part at the level of the lower annular edge of the container. Thus the height of the intermediate part of the second elastic hinge is close to the height of the lower annular rim of the container.

According to another embodiment, the sealed cover may comprise another attachment member connected to the closure piece by another first elastic hinge, the closure piece being arranged between the attachment member and the other hooking member, the other hooking member being configured to come into engagement with the ring, so that the annular support element provides a seal with the upper edge when the ring bears under the annular rim lower and that the other attachment member is engaged with the ring.

The other first elastic hinge and the other hooking member can belong to the body.

If desired, the tight cover can include a second elastic hinge connecting the obturation part to the ring.

Alternatively, the ring can be independent of the closure piece. Thus the ring can be independent of the body. The annular joint can be configured to bear against the upper edge when the ring bears under the lower annular rim and the hooking member and the other hooking member are in engagement with the ring.

The other attachment member may have a construction similar to that of the attachment member. The other attachment member may have another hook configured to come into engagement with the lower edge of the ring when the other attachment member is in engagement with the ring. The other hook can be engaged in another lower housing of the ring adjacent to the lower edge when the other hooking member is in engagement with the ring. The other attachment member may have another second hook configured to come into engagement with another lower rib of the body when the other attachment member is in engagement with the ring.

These objects are also achieved with a container comprising a container and a tight lid, in which the container comprises an upper edge and a side wall having a lower annular rim, because the tight lid conforms to at least one of the characteristics aforementioned.

The container can be made of glass, which is particularly interesting for a reusable food container.

The invention will be better understood on studying two exemplary embodiments, taken in no way limiting, illustrated in the appended figures, in which:

[Fig 9] Figure 9 is a perspective view of an embodiment of a container comprising a container and a sealed lid according to the invention made in two parts,

[Fig 10] Figure 10 is a cross-sectional view of the sealed lid shown in Figure 9 mounted on the container shown in Figure 9.

The container 3 illustrated in Figures 1, 7 and 8 comprises a container 1 and a sealed lid 2. The container 1 is intended to contain food. The tight lid 2 makes it possible to close the container 1 . Container 3 can be used for transporting or storing the food contained in container 1.

The container 1 can in particular be used for the preparation of yoghurts. To this end, the container 1 is advantageously made of glass.

As best seen in Figure 2, the container 1 has an upper edge 10 and a side wall 12 having a lower annular rim 14. The upper edge 10 is extended by an outer annular side rim 11 . The container 1 has a side wall 12 and a bottom 13. The side wall 12 has a lower annular rim 14 arranged outside the container 1 under the outer annular side edge 11 . The lower annular flange 14 can be provided to rest on an edge of an opening of a container support, in order to suspend the container 1 in said opening. The tight lid 2 is configured to be used with the container 1 having the upper edge 10 and the side wall 12 having the lower annular rim 14, to form the container 3.

The container 1 and the sealed cover 2 illustrated in the figures have a square geometry. The side wall 12 has several faces 15 interconnected by curved areas 16, and the lower annular rim 14 has several segments connected by rounded parts. Thus the side wall 12 and the lower annular rim 14 have non-circular geometries. Other polygonal geometries, for example hexagonal, or non-polygonal, for example elliptical or circular, are however possible for the side wall 12 and the lower annular rim 14.

As best seen in Figures 3 and 4, the sealed lid 2 comprises an annular support element 20 configured to bear annularly on the upper edge 10 of the container 1. The sealed lid 2 comprises a closure piece 30 configured to close the upper opening of the container 1 in association with the annular support element 20. The sealed lid 2 comprises a hooking member 40 connected to the closure 30 by a first elastic hinge 50.

The sealed cover 2 comprises a ring 60 connected to the closure part 30 by a second elastic hinge 70. The first elastic hinge 50 and the second elastic hinge 70 are arranged on either side of the closure part 30. The ring 60 is configured to be mounted around the container 1 to come to rest under the lower annular rim 14. The attachment member 40 is configured to come into engagement with the ring 60 so that the annular element d The support 20 provides a seal with the upper edge 10 when the ring 60 bears under the lower annular rim 14 and the attachment member 40 is in engagement with the ring 60.

The sealed lid 2 is thus removable with respect to the container 1, and may have a configuration in which the container 1 and the sealed lid 2 form a sealed container.

The materials used for the sealed cover 2 are chosen to allow the preservation of food, see the freezing of food. In the embodiment illustrated in the figures, the ring 60, the first elastic hinge 50, the closing part 30, the second elastic hinge 70 and the attachment member 40 belong to a body 80, illustrated on Figure 5.

If desired, the body 80 can be made of transparent or translucent material.

In the embodiment illustrated in the figures, the annular support element 20 is formed by an annular gasket 21 configured to bear against the upper edge 10 when the ring 60 bears under the lower annular rim 14 and the attachment member 40 is engaged with the ring 60, as seen in Figure 8.

As seen in Figure 3, the annular seal 21 has a first bearing face 22 having annular ribs 23. In the embodiment illustrated in Figure 3, the first bearing face 22 has three annular ribs 23 Preferably, the first bearing face 22 has between two and four annular ribs 23. The first bearing face 22 is configured to bear against the upper edge 10 when the ring 60 bears under the lower annular rim 14 and that the attachment member 40 is in engagement with the ring 60.

As best seen in Figure 5, the body 80 has a peripheral lower annular rib 81 . Seal ring 21 is mounted under body 80 within peripheral lower annular rib 81. If desired seal ring 21 can be removed for cleaning or replacement. The body 80 has an inner lower annular rib 82 surrounded by the peripheral lower annular rib 81 . The peripheral lower annular rib 81 and the inner lower annular rib 82 provide an annular groove 84. The annular gasket 21 is mounted under the body 80 between the peripheral lower annular rib 81 and the inner lower annular rib 82. In other words, the annular seal 21 is mounted in the annular groove 84. This arrangement makes it possible to improve the seal between the upper edge 10 and the annular seal 21 . As seen in Figure 6, the annular seal 21 has a second bearing face 24 opposite the first bearing face 22. The second bearing face 24 has annular ribs 25. In the embodiment illustrated in FIG. 6, the second bearing face 24 has three annular ribs 25. Preferably the second bearing face 24 has between two and four annular ribs 25. The second bearing face 24 is configured to be mounted between the peripheral lower annular rib 81 and the inner lower annular rib 82.

As seen in Figures 1, 3, 4, 5, 7 and 8, the first elastic hinge 50 is arranged opposite the second elastic hinge 70 with respect to the closure piece 30.

As best seen in Figures 3, 4 and 5, the ring 60 has four sides 61, 62, 63, 64. The second elastic hinge 70 is connected to a first side 61. The attachment member 40 is configured to come into engagement with a second side 62 opposite the first side 61 . A third side 63 and a fourth side 64 extend between the first side 61 and the second side 62.

As best seen in Figures 3, 5, 7 and 8, the second elastic hinge 70 comprises a first elastic part 71 connected to a second elastic part 72 by an intermediate part 73 more rigid than the first elastic part 71 and more rigid than the second elastic part 72. The first elastic part 71 is connected to the ring 60. The second elastic part 72 is connected to the closure piece 30.

In the exemplary embodiment illustrated in the figures, the attachment member 40 has several attachment elements. As best seen in Figures 3, 4, 57 and 8, the attachment member 40 has a hook 41 and a second hook 42. As best seen in Figure 8, the hook 41 is configured to come into engagement with a lower edge 65 of the ring 60 when the attachment member 40 is engaged with the ring 60. The hook 41 is engaged in a lower housing 66 of the ring 60 adjacent to the lower edge 65 when the hooking member 40 is engaged with the ring 60. The second hook 42 is configured to come into engagement with a lower rib 83 of the body 80 when the hooking member 40 is engaged with the ring 60. In the embodiment illustrated in the figures, the lower rib 83 is formed by a part of the peripheral lower annular rib 81 . If desired, the lower rib 83 can be distinct from the peripheral lower annular rib 81 , or the body 80 can have no peripheral lower annular rib 81 . In the embodiment illustrated in the figures, the hook 41 is larger than the second hook 42.

The tight lid 2 and the container 3 illustrated in Figures 1 to 8 are used as follows.

The user can store the sealed cover 2 flat, as shown in Figures 3 and 4.

To close the container 3, the user positions the ring 60 under the lower annular rim 14 of the container 1. The user then pivots the closure part 30 according to the second elastic hinge 70 so that the annular element of support 20 comes to bear in an annular manner on the upper edge 10 of the container 1, and also causes the attachment member 40 to pivot according to the first elastic hinge 50 so that the attachment member 40 comes into engagement with the ring 60. The hook 41 is then engaged in the lower housing 66, and the second hook 42 then comes into engagement with the lower rib 83 of the body 80 formed by a part of the peripheral lower annular rib 81 . The container 3 is then sealed and can be used for transport or storage.

To open the container 3, the user disengages the hooking member 40 from the ring 60 by pivoting it according to the first elastic hinge 50, then disengages the annular support element 20 from the upper edge 10 of the container 1 by pivoting the closure part 30 according to the second elastic hinge 70. The user can then remove the ring 60 from the container 1 .

The construction proposed makes it possible to obtain a resealable container 3 using a container 1 having undemanding dimensional tolerances, such as for example a container 1 made of glass. The attachment of the attachment member 40 to the ring 60 makes it possible to achieve a tight closure of the container 3 by compressing the annular bearing element 20 of the tight lid 2 against the upper edge 10 of the container 1 . The sealed lid 2' illustrated in Figures 9 and 10 is also configured for use with the container 1 having the upper edge 10 and the side wall 12 having a lower annular rim 14. Like the sealed lid 2, the sealed lid 2' comprises an annular support element 20 configured to bear in an annular manner on the upper edge 10, a closure piece 30', and a hooking member 40 connected to the closure piece 30' by a first elastic hinge 50. The sealed cover 2' comprises a body 80' made of plastic material, comprising the closure piece 30', the first elastic hinge 50 and the attachment member 40.

The sealed lid 2' comprises a ring 60' configured to be mounted around the container 1 to come to rest under the lower annular rim 14. The hooking member 40 is configured to come into engagement with the ring 60' so that the annular bearing element 20 ensures a seal with the upper edge 10 when the ring 60' bears under the lower annular rim 14 and that the attachment member 40 is engaged with the ring 60', as shown in figure 10.

The sealed cover 2 'illustrated in Figures 9 and 10 differs from the sealed cover 2 illustrated in Figures 1 and 3 to 8 in that it comprises another attachment member 40' connected to the closure piece 30' by another first elastic hinge 50', and in that it does not include a second elastic hinge connecting the ring 60' to the closing piece 30'. Thus the 60' ring is independent of the 30' blanking piece. The other attachment member 40' can be identical to the attachment member 40.

The ring 60', the closing part 30, the first elastic hinge 50, the attachment member 40, the other first elastic hinge 50' and the other attachment member 40' belong to the body 80' . The 60' ring is independent of the 80' body.

As best seen in Figure 10, the closure piece 30 'is arranged between the attachment member 40 and the other attachment member 40'. The other hooking member 40' is configured to come into engagement with the ring 60', so that the annular support element 20 provides a seal with the edge upper 10 when the ring 60' bears under the lower annular rim 14 and the other attachment member 40' is in engagement with the ring 60'.

The annular seal 21 is configured to bear against the upper edge 10 when the ring 60' bears under the lower annular rim 14 and the hooking member 40 and the other hooking member 40' are engaged. with the 60' ring.

The other attachment member 40' has another 4 T hook configured to come into engagement with a lower edge of the ring 60' when the other attachment member 40' is engaged with the ring 60'. The other 4 T hook is engaged in another lower housing 66' of ring 60' adjacent to the lower edge when the other attachment member 40' is in engagement with ring 60'. The other attachment member 40' has another second hook 42' configured to come into engagement with another lower rib of the body 80' when the other attachment member 40' is engaged with the ring 60'.

As best seen in Figure 9, the ring 60 'has four sides 61, 62, 63, 64. If desired the four sides 61, 62, 63, 64 can be identical. The attachment member 40 is configured to come into engagement with one of the sides 61, 62, 63, 64. The other attachment member 40 'is configured to come into engagement with another of the sides 61, 62 , 63, 64 opposite the aforementioned side.

If desired, the sealed cover 2' can include a second elastic hinge connecting the closing part 30 to the ring 60'.

The 2' tight lid and the 3' container illustrated in figures 9 and 10 are used as follows.

The user mounts the ring 60' under the lower annular rim 14 of the container 1. If desired, the user can permanently mount the 60' ring on the container 1 . In other words, the ring 60 'can be configured to be mounted slightly in force around the side wall 12 of the container 1 under the lower annular rim 14.

To close the container 3', the user positions the body 80' on the container 1 so that the annular support element 20 comes to bear in such a way ring on the upper edge 10 of the container 1.

The hook 41 and the other 4 T hook are then engaged respectively in the lower housing 66 and in the other lower housing 66'. The second hook 42 and the other second hook 42' then come into engagement with the lower rib 83' of the body 80'. The container 3 is then sealed and can be used for transport or storage.

To open the container 3, the user disengages the attachment member 40 from the ring 60' by pivoting it according to the first elastic hinge 50, then the other attachment member 40' from the ring 60' by pivoting it according to the other first elastic hinge 50. The user can then lift the annular support element 20 from the upper edge 10 of the container 1.

The proposed construction also makes it possible to obtain a resealable 3′ container using a container 1 having undemanding dimensional tolerances, such as for example a glass container 1. The hooking of the hooking member 40 and of the other hooking member 40' to the ring 60' makes it possible to achieve a sealed closure of the container 3 by compressing the annular support element 20 of the sealed lid. 2' against the upper edge 10 of the container 1 .

Alternatively, at least part of the closure part 30; 30’ can belong to body 80; 80' made of plastic material forming the first elastic hinge 50 as well as the other first elastic hinge 50' and/or the second elastic hinge 70. The closure piece 30, 30' may include an insert, in particular an insert made of transparent or translucent, for example a glass insert. The body 80; 80' can then be molded onto the insert.

Alternatively, the sealed cover 2; 2 'does not necessarily include an annular bearing element 20 formed by an annular seal 21 mounted in a peripheral lower annular rib 81 of the body 80; 80'. According to an alternative embodiment, not illustrated in the figures, an annular seal could in particular be molded onto the body 80; 80'.
