Description

Title of the invention: Assembly forming a food storage container. FIELD OF THE INVENTION

[0001] The invention relates to an assembly forming a food storage container, with a storage container and a lid that can be separated from it. PRIORITY OF THE TECHNOLOGY

[0002] Such an assembly forming a storage container is known from DE 10 2004 063 398 A1. The peripheral sealing gasket on the lower side of the lid presses against the upper edge of the storage container, creating a liquid-tight seal when the lid is snapped into place against a locking protrusion on the side wall of the storage container, via several snap-on tabs distributed around the periphery. A force is simultaneously exerted on the lid when it is snapped into place. The lid, along with its elastomer sealing gasket, is pulled up to the upper edge and held in a pre-tensioned position. The airtight and liquid-tight seal ensures hygienic food storage and trouble-free transport.Users find it inconvenient that a high preload must be applied to the locking tabs, requiring significant force to open and close them. Furthermore, multiple locking tabs must always be opened or closed, typically two pairs of tabs facing each other. DISCLOSURE OF THE INVENTION

[0003] The objective of the present invention is to improve an assembly forming a storage container of the prior art mentioned in the introduction, so that more comfortable handling is made possible when opening and closing the lid, in particular with fewer locking positions, a reliable airtight and liquid-tight connection being guaranteed as before between the storage container and the lid after closing.

[0004] This objective is achieved by means of an assembly forming a food storage container, with a storage container and a lid that can be separated from it, where the storage container: - has a base and a side wall that terminates against a top edge and - the side wall has at least one locking element against at least two side wall sections respectively; - and in which the lid - can be fixed against the hinge-free storage container by complementary shape via locking elements, - features at least one peripheral sealing profile made of elastomer, and - has at least one internal support crossbar on its lower side extending at least partially along the periphery of the lid, which support crossbar can be positioned inside the upper edge of the storage container,

[0005] characterized in that - against the cover is designed at least one locking element as a fixed hook section against the edge of the cover and in addition, on the periphery and facing, at least one locking element is designed as a snap hook against a pivoting snap tab; - at least one locking element is formed against the storage container by a peripheral locking projection against the side wall and / or by a snap-on edge against the upper edge of a recess in the side wall of the storage container; - the lid placed on the storage container engages with the hook section under the locking protrusion against the side wall or under the snap-on edge against the upper edge of a recess in the side wall.

[0006] This solution requires only a minimum of two locking units facing each other on the periphery of the lid. Among these, at least one locking position is designed with at least one pivoting snap-on tab connected to the lid. This snap-on tab can be fixed, without a hinge, by means of a molded element, against a locking projection on the storage container.

[0007] The second locking unit is formed either by a second snap-on tab of the same type, or, according to a preferred embodiment, by a non-movable locking element which, when the lid is slightly angled, can be hooked under the locking protrusion of the storage container and initially holds the lid on one side by complementary shape. The lid is then pressed against the upper edge of the storage container and locked by complementary shape against the storage container with the movable snap-on tab present at the facing end.

[0008] In this preferred embodiment with at least one rigid locking element and at least one movable locking element, only a single locking element, in the form of a movable snap-on tab, needs to be manipulated to connect the lid to the storage container or to release it from the container, thus creating a liquid seal. This facilitates one-handed operation: the lid can first be hooked against the storage container on one side, and then the movable snap-on tab is pressed down with one hand on the other side until it is in the hooked position. Conversely, to open the lid, it is sufficient to release a single snap-on tab, position the lid at an angle, and then remove it from the hook by aligning its shape with the storage container.

[0009] The locking units described on facing sides may also be formed by several locking elements located close to each other but separated from each other. In this case, the locking locations refer to locking areas facing each other against the storage container, in which several functionally identical locking elements are arranged side by side.

[0010] The locking projection against the container wall should preferably have an undercut in the profile, as should the corresponding movable locking element or the non-movable locking element, so that a safe form complementarity is obtained.

[0011] The locking projection can, for example, be designed as a crossbar extending outwards from the outer wall of the container. This configuration is preferred for plastic containers in order to maintain a thinner wall of the storage container. It is also preferred for stainless steel storage containers, for which a thinner wall is essential.

[0012] A recess can also be designed in an external side of the container, the upper edge of which forms the locking projection. This is advantageous for thick-walled storage containers, which are, for example, made of ceramic or glass.

[0013] Thus, it is possible to combine the same lid with storage containers made of different materials.

[0014] In order to ensure the airtightness of the assembly forming a closed storage container despite the reduced number of locking points compared to the prior art, a special sealing system is provided, which is based on a flexible sealing lip that is applied from the inside against the container wall. The sealing lip forms the end of a J-shaped sealing profile in the cross section, which also forms an edge section of the lid and is made of an elastomeric material, in particular a TPE.

[0015] In this way, an upper cross-section of the sealing profile is provided to come into contact with the upper edge of the side wall when the lid is placed. Even though a pressure force from this cross-section on the upper edge can only be exerted in the peripheral areas where the locking units are arranged, the upper elastomer cross-section nevertheless increases the sealing of the entire storage container assembly by creating a second sealing layer in addition to the sealing lip located inside.

[0016] The shaping of the sealing profile is also essential thereafter. Thus, a central section connects to the upper cross-section, which central section is guided downwards towards the interior space of the container, and then extends into an arched section at the end of which the sealing lip is in turn designed. Thanks to the arched shape, the sealing lip can spring back elastically when the lid is placed on the storage container, but nevertheless remains pressed against the inner wall.

[0017] In order to maintain the sealing effect resulting from the elastic restoring force of the arched section and the sealing lip in a lasting manner, a preferred embodiment of the invention provides two additional measures:

[0018] Thus, what is called the central section, from which the arched section originates, is supported against a vertical support cross member that forms part of the central area of ​​the lid. The central area of ​​the lid is made of a plastic material that is harder than the plastic material of the edge section. The central area is, for example, made of polypropylene and the edge section of a thermoplastic elastomer.

[0019] The central zone comprises a surface section that covers the entire interior space within the edge element and further includes at least one inclined support cross member in contact with the elastomer edge zone. Thanks to the support cross member of the central zone, its contact area with the elastomer edge zone is increased, thereby making the bond between the two more secure against delamination.

[0020] In addition, the support cross supports the central section of the elastomer edge area, thus preventing it from having the possibility of moving inwards under the effect of elastic prestress, whereby the sealing lip could lose its firm contact with the inner wall of the container.

[0021] Furthermore, to prevent the container wall from being pushed outwards, a clamping ring is preferably connected from the edge section, which is located immediately before the outer wall of the container. The clamping ring prevents the container wall from bulging outwards.

[0022] Preferably, the outer wall of the storage container has a locking projection on its upper edge that extends continuously around its entire periphery and is therefore not only present at the locations against which the locking units described above are applied. The locking projection serves to hook snap-on elements against the lid and, moreover, due to the enlargement of its cross-section, has a stiffening function for the upper edge area of ​​the outer wall of the container.

[0023] The clamping ring is preferably an external profile section integrated into the edge section of the lid, formed from an elastomer. When the storage container assembly is closed, the upper edge of the storage container is positioned between the external clamping ring and the internal central crossbar. The central crossbar maintains a sufficient distance from the inner side of the container wall to facilitate the deformation of the curved area and the sealing lip. Furthermore, the clamping ring is positioned directly against the outer wall of the container to prevent outward deformation of the container wall.

[0024] The profiling of the edge area, including the adjacent sections of the central area, is important to achieve the sealing of the assembly forming a storage container according to the invention; however, it must also fulfill other functions during the use of the assembly forming a storage container, such as for the manufacture of the lid.

[0025] Thus, in a preferred embodiment of the lid, a cross-section of the edge area, the central and arched sections connecting to it and the sealing lip connecting to it in turn are preferably profiled so that the upper side of the sealing lip is oriented horizontally with respect to a lifting plane when the assembly forming the storage container is closed, or even ends slightly sloping outwards, in any case so that the formation of a groove in which liquid can accumulate is avoided.

[0026] Furthermore, the profiling of the edge area must allow the cover to be manufactured using a two-component injection molding process. Since significant inward deformation of the elastomer edge area is not possible due to the preferably rigid central area with its support crossbar, the preferred embodiment must allow the cover to be demolded from an injection mold. This is achieved by forming a trapezoidal internal space between the external clamping ring and the central crossbar, the crossbar of which narrows slightly upwards. The support crossbar of the area central extends downwards only until the arched section with the sealing lip can move outwards under the lower edge of the support cross member.

[0027] Preferably, a parting plane is located in the injection mold approximately at the height of the bearing surface formed by the upper cross-section, such that the outer periphery of the edge section is divided into a lower and an upper part, both parts extending towards the parting plane at a slight outward angle. The lower part of the outer periphery of the edge section is formed by the clamping ring, which, viewed in cross-section, has a slightly trapezoidal shape and tapers downwards.

[0028] Furthermore, to facilitate the release of the lid previously attached to the storage container, at least one vent valve is preferably integrated into the lid so that pressure compensation can be achieved with respect to the environment. In doing so, a pressure force exerted by the lid on the storage container, based on differential pressure, can be eliminated. To lift the lid, only a small force is still required to overcome the friction force of the sealing lip rubbing against the inner wall of the container. The vent valve thus facilitates one-handed operation or makes it possible when, due to temperature differences between the food placed in the container and the ambient temperature, a pressure difference is established after the lid has been placed and locked.

[0029] The venting valve includes at least one venting channel extending from the outer side of the lid, through the elastomer rim area, and to an opening in the container. An opening at the mouth of the venting channel on the outer side is locked by a valve closure element when the movable latching tab is snapped against the storage container. The container is thus sealed. As soon as the latching tab is disengaged, the venting channel is also released, allowing pressure equalization between the inside of the container and the environment.Whereas in the prior art, for ventilation openings, a small elastic valve closing element is most often pressed against an opening in a rigid structure, the invention reverses the choice of material properties, i.e., a rigid valve closing element is pressed against a mouth opening in an elastic structure. In doing so, a small, concave, hump-shaped valve closing element suffices, which is formed directly against the snap-on tab. Therefore, no separate part against the snap-on tab is necessary, as such a separate part would have had to be fixed as a single piece and could easily detach during use.

[0030] Preferred but not limiting aspects of this assembly forming a storage container, alone or in combination, are as follows: - the storage container: - has a base and a side wall that terminates against a top edge and - the side wall has at least one locking element against at least two side wall sections respectively; - and the lid - can be fixed against the hinge-free storage container by complementary shape via locking elements, - features at least one peripheral sealing profile made of elastomer, and - has at least one internal support crossbar on its lower side extending at least partially along the periphery of the lid, which support crossbar can be positioned inside the upper edge of the storage container,

[0031] characterized in that - against the cover is designed at least one locking element as a fixed hook section against the edge of the cover and in addition, on the periphery and facing, at least one locking element is designed as a snap hook against a pivoting snap tab; - at least one locking element is formed against the storage container by a peripheral locking projection against the side wall and / or by a snap-on edge against the upper edge of a recess in the side wall of the storage container; - the lid placed on the storage container engages with the hook section under the locking protrusion against the side wall or under the snap-on edge against the upper edge of a recess in the side wall. - the lid includes a central area with the support cross extending downwards and an elastomer edge area surrounding the central area, in which the sealing profile is integrated or which is formed by the sealing profile; and outside the periphery of the side wall, in the edge area, is designed a clamping ring which extends below the upper rim of the storage container. - the clamping ring extends downwards to below the upper rim of the storage container. - the edge area is profiled in a J shape in the cross section, in which on one side the clamping ring connects against the upper cross section, and on the other side the central section connects with the arched section and the sealing lip. - when the cover is in place, an upper cross-section of the edge area is in contact with the upper edge of the side wall, a central section is guided downwards along the support cross-section and pressed against it; the central section extends into an arched section which moves away from the support cross-section and terminates in a sealing lip which is in contact with the inner wall of the side wall. - the entire edge area is formed in a thermoplastic elastomer and the central area in a comparatively harder thermoplastic material. - the snap tab is connected to the central area of ​​the lid via a bridge area made of non-elastic plastic material. - the storage container has a rectangular cross-section with two short side wall sections and two long side wall sections, and in that the snap tab and hook section are arranged facing each other in the short side wall sections. - against the cover is provided at least one ventilation valve which includes at least one ventilation channel and at least one movable closing element via the snap tab for closing the ventilation channel, the ventilation channel extending through the edge area.

[0047] Figure 1A shows a storage container assembly 100 with a storage container 10 and a lid 20 placed on top of it, in a perspective view. The storage container 10 comprises a base 12 and a side wall 11 with a predominantly rectangular cross-section, and strongly rounded transition zones 11.3 existing between sections of the side wall 11.1, 11.2. The side wall 11 has a stacking rim 15.

[0048] The lid 20 comprises a central zone 21, which is in particular made of a transparent plastic material, e.g., polypropylene, and an edge zone 23, which is formed from a thermoplastic elastomer. The lid 20 engages with a hook section 25 under a locking projection, not visible here, against the outer side of the storage container 10. The hook section 25 and the locking projection form a first locking unit.

[0049] On the narrow side of the storage container 10, facing the hook section 25, a snap-on tab 30 is connected to a bridge area 26 of the edge area 23 via a film hinge 32. The bridge area 26 is made, like the snap-on tab 30 and the film hinge 32, of the same plastic material as the central area 21.

[0050] The snap-on tab 30 has two snap-on hooks 31 on its lower side to be oriented towards the side wall 11. The snap-on tab 30 and the hook section 25 serve to connect by complementary shape with the side wall sections 11.1, 11.2 face each other in pairs, and form a second locking unit.

[0051] Fig. IB shows the assembly forming the storage container 100 completely closed in a perspective view. The snap-on tab 30 is brought close by pivoting against the side wall 11, so that there is a lock by complementary shape between the lid 20 and the storage container 10.

[0052] Figure 2 shows the lid 20 alone in a perspective view from below. In particular, an internally peripheral sealing lip 23.4 is visible. Below the snap-on tab 30, the edge area 23 is interrupted in a section of the edge area 28 to allow the snap-on tab 30 to be tightly pressed against the side wall 11 of the storage container. The sealing lip 23.4 extends without any interruption around its entire periphery.

[0053] On the lower side of the snap-on tab 30 are formed two snap-on hooks 31 as well as a valve closing element 42, through which the inlet opening of a ventilation channel 41 can be closed when the snap-on tab 30 is lowered and locked against the edge of the container.

[0054] Fig. 13 shows how the lid 20 is brought into contact with the storage container 10 by guiding it. For this purpose, it is positioned at an angle and hooked under the locking projection 14 with the hook section 25 located at the bottom, then pivoted downwards onto the upper edge 134, as indicated by the arrow.

[0055] Figure 3 shows a perspective cross-sectional view along the central axis between the two long side walls 11.2 of the storage container assembly 100. The edge zone 23 of the lid 20 rests on and encloses an upper edge 13 of the side wall 11. The elastomer edge zone 23 is pressed inwardly against a cross member of the central zone 21 made of a hard thermoplastic material. The central zone 21 is connected to the support cross member 22 by complementary materials. The support cross member 22 is interrupted where a ventilation channel 41 opens into the interior space of the container.

[0056] Fig. 4 is an enlarged representation of the area marked in the upper left of Fig. 3. The profiling of the edge section 23 becomes particularly clear in this representation. It comprises, firstly, an upper cross-section 23.1 which has a bearing surface on its lower side against which the edge area 23 rests on the upper edge 13 of the side wall 11. On an inner flank, the cross-section 23.1 is connected by complementary material to the support cross member 22 of the central region 21. On this side and moving downwards, the cross-section 23.1 continues as a central cross member 23.2. The central cross member 23.2 is also supported by the support cross member 22. The edge zone 23 is connected to the central zone 21 by complementary shape.

[0057] Below the support cross member 22, the central cross member 23.2 extends into an arched section 23.3 which terminates in a tapering sealing lip 23.4. On the outer side of the edge area 23, another vertical cross member is provided which extends downwards from the cross section 23.1 and serves as a clamping ring 23.5 to prevent swelling of the side wall 11 under the pressure of the arched area 23.3, including the elastically deformed sealing lip 23.4.

[0058] In the representation of [Fig.4], the tip of the sealing lip 23.4 appears to continue into the side wall of the container 11. This representation is evident from the fact that the sealing lip 23.4 and the arched section 23.3 are shown undeformed and are in fact designed with a certain excess to ensure a constant application of the sealing lip 23.4 against the inner wall of the container in the context of maintaining a constant prestress.

[0059] Fig. 5 shows a cross-section of the assembly forming the storage container in the area of ​​the hook section 25. In doing so, it can be seen that the hook section 25 is designed with an undercut and that it is hooked into the area of ​​the upper rim 13 under the locking projection 14 which is also undercut.

[0060] Figure 6 is a detail of a slanted perspective view from the bottom of the assembly forming the storage container. The lid 20 is placed on the side wall 11. The snap-on tab 30 is folded upwards; the valve closing element 42 formed against it is away from the ventilation channel.

[0061] Fig. 7 shows the same view as Fig. 6 after pivoting downwards the snap-on tab 30. The snap-on hooks 31 of the snap-on tab 30 engage under the locking projection 14 against the side wall 11. The snap-on tab 30 is applied tightly against the storage container 10 so that its outer side is essentially flush with the edge area 23 of the lid 20.

[0062] Figure 8 again shows the situation before the lid 20 is locked against the storage container 10 from a slightly different, but similar, angle of approach to Figure 6. In doing so, the position of the closing element 42 near the opening of the vent channel 4L is particularly visible. The valve closing element 42 and the vent channel 41 together form a vent valve 40. The vent channel 41, which is not yet closed, allows air to enter or leave the interior space of the container.

[0063] The edge zone 23 is partially interrupted in the edge zone section 28. In the edge zone section 28, a portion of the upper cross-section 23.1 and a portion of the clamping ring 23.5 connecting to it are missing from the profile. The area below has also been removed. However, there is no interruption in the contact zone with the side wall 11 to ensure the sealing of the assembly forming the storage container.

[0064] Figure 9 shows the same approach as Figure 8, but without the container conservation. In doing so, the position of the ventilation channel 41 becomes particularly clear. This extends from the opening in the edge zone section 28 to the interior space, the ventilation channel 41 being guided so deeply that the casing of the ventilation channel 41 extends beyond the cross-section profile of the edge section 23 and connects at this point, as a cross member 24, to the interior against the edge zone 23. Thanks to this design of the ventilation channel 41, the central section 21 can, on the one hand, be arranged vertically to deploy its stiffening effect for the edge zone 23, which is particularly visible in Figures 3 to 5. On the other hand, the cross member 24 also serves to support the elastomer zone all around the ventilation channel 41, since in this area, an interruption of the support cross member 22 is necessary for the mouth of the ventilation channel 41 (see [Fig.3]).

[0065] Figure 10 shows part of a longitudinal section running through The locking area of ​​the lid 20 with the storage container 10 by means of the snap tab 30. The valve closing element 42, on the rear side of the snap tab 30 made of hard plastic, presses on the environment of the relatively softer rim area 23, and thus closes the opening of the ventilation channel 4L. It can be seen in [Fig.10] that the ventilation channel 41 starting from the upper side of the rim area 23 runs just slightly above the upper edge 13 of the storage container 10, thus extending diagonally downwards, then opening into the interior space of the container below the central area 21.

[0066] Figure 11 shows a representation identical to that of Figure 10, but with the The latching tab 30 is open. The valve closing element 42 on the rear side of the latching tab 30 is moved away by pivoting from the opening of the ventilation channel 41 so that the latter is now open.

[0067] Figure 12 represents a detail of a perspective view of an assembly forming A storage container 100' according to a second embodiment, with an approach from below via a snap-on tab 30'. The storage container 10 with its side wall 11 remains unchanged. A lid 20' also largely corresponds to the embodiment of the lid 20 described above. The difference with the lid 20' is that two ventilation channels 41 open into a section of the edge zone 28' of an edge zone 23', and a recessed handle 29' is designed between the two. In doing so, the snap-on tab 30' tightly applied against the side wall 11 in the locked position can be better gripped and unlocked. Reference signs#:
