Description

Title: PACKAGING FOR THE PACKAGING OF BIVALVE SHELLFISH

Technical area

The invention relates to the field of packaging for bivalve shellfish and in particular packaging for oysters.

Prior technique

[0002] It is known from document FR2 686 068 to produce a packaging for the packaging of shellfish such as oysters which comprises a lower support such as a hollow tray and a lid provided with wedging zones facing the tray.

Technical problem

[0003] Such a known solution requires positioning the shells precisely on the board or choosing their size so that they are found under the wedging zones. In addition, such packaging is not suitable for stacking.

Disclosure of Invention

[0004] In view of the prior art, this application proposes a packaging suitable for being stacked and reducing the positioning constraints of bivalve shellfish.

To do this, the present invention provides a stackable packaging packaging for bivalve shellfish comprising a tray surrounded by a peripheral wall projecting above an upper face of the tray, for which an underside of the tray is provided with one or more means for resting on one or more rows of said shells of a lower packaging packaging of the invention so as to keep the shells of said shells of said lower packaging packaging closed and for which the peripheral wall of the packaging comprises an embedding profile with an upper and/or lower packaging packaging of the invention. [0006] The peripheral wall may comprise an upper embedding profile and a lower embedding profile made by adding a reinforcing strip to at least one outer face of an inner wall of said peripheral wall, said reinforcing strip being offset with respect to said internal wall to protrude from a first edge of said internal wall and to be set back from a second edge of said internal wall so as to allow the stacking of the packaging with an upper packaging and/or a lower packaging.

[0007] The tray of the packaging can in particular be round, oval, rectangular or prismatic.

[0008] Said one or more support means can be made in the form of a continuous spring tongue, discontinuous spring tongues or in the form of ribs, pins or slots.

[0009] Said support means can be aligned according to a positioning pattern of said seashells flat on the plate so as to press on each of the shells of said seashells of a lower packaging.

[0010] A lower part of said peripheral wall can protrude under said support means to form a laying face for the flat packaging and a housing for receiving an upper wall of a tray of a lower packaging.

[0011] Alternatively, said peripheral wall may comprise an upper housing for receiving a tray of an upper packaging.

[0012] An upper face of the plate may comprise ribs for positioning said shells in rows.

The upper face of the tray can be positioned relative to an upper edge of the peripheral wall of the packaging at a depth adapted to have the top of the shells of said shellfish of a given caliber flush with the upper face of the 'packaging.

[0014] The packaging can be supplemented with a cover so as to keep the shells of the shellfish placed in the upper packaging of a stacking said packages, said packages of the stack can then be strapped.

[0015] The invention and the variants thereof can make it possible, in general, to offer packaging packaging for stackable shellfish and provided with means for closing the shells of lower packaging when the packaging is stacked, said packaging of packaging that can, once separated, be used as a presentation tray for the shellfish.

[0016] Such a solution makes it possible to solve the problems posed by the known solutions and, depending on the surface of the trays, which can for example be adapted to the packaging of 6, 12, 24 shells, to allow the packaging, transport and sale of shellfish in a packaging directly usable as a presentation tray in quantities adapted to the wishes of the consumer.

Description of embodiments

[0026] The drawings and the description below contain, for the most part, certain elements. They may therefore not only be used to better understand the present invention, but also contribute to its definition, if necessary.

[0027] According to the example of Figure 1, a packaging package 1 for bivalve shellfish comprises a plate 2 surrounded by a peripheral wall 3 projecting above an upper face of the plate. Such a tray shown in sectional perspective can be rectangular as in the figure but also round, oval, rectangular or prismatic.

According to a first aspect, an underside 21 of the tray is provided with one or more support means 6 on one or more rows of said shells of a lower packaging packaging of the invention.

Figures 3A and 3B show in two embodiments which will be detailed later such a support whose purpose is to keep closed the shells of shells 10 of a packaging packaging of the lower description.

[0030] Returning to Figure 1, according to another aspect, the peripheral wall of the packaging comprises an embedding profile 71, 72 with an upper and/or lower packaging packaging of the invention. The peripheral wall 3 comprises an upper embedding profile 71 and a lower embedding profile 72 of opposite direction, one 71 protruding towards the outside of the wall and the other 72 towards the inside of the wall.

[0031] The embedding profiles are made by adding a reinforcing strip 5 to at least one outer face of an inner wall 4 of said peripheral wall 3. [0032] The reinforcement strip is offset with respect to said internal wall to protrude from a first edge of said internal wall and be set back from a second edge of said internal wall so as to allow the stacking of the packaging with a upper packaging and/or lower packaging.

According to Figure 2A, the reinforcement strip 5a is offset upwards, the peripheral wall then comprising an upper housing 32 for receiving a tray 2b of an upper packaging as shown in Figure 3A showing the recess of the tray upper 2b in the housing formed by the upper part of the strapping 5a and the support of the tab 6b on the shell 10a positioned on the lower plate 2a.

[0034] This embodiment provides good support for the packages in each other when they are stacked and does not require very fine calibration of the shells, the height of the wall being such that it protrudes above the shells. .

[0035] According to Figure 2B, the reinforcement strip 5b is offset downwards, said peripheral wall protruding under said support means 6 to produce a laying face for the flat packaging and a housing for receiving a wall upper 33 of a tray of a lower package.

This embodiment is found in Figure 3B and in this case it is possible to choose the heights of the walls 4 and 5b to be able to position the upper face 22 of the plate is positioned at a depth h with respect to an upper edge 33 of the peripheral wall of the packaging such that I depth h is adapted to have the top of the shells of said shellfish of a given caliber flush with the upper face of the packaging while maintaining a space above this packaging for maintain an elastic support of the tabs 6 of the upper packaging on the shells of the lower packaging.

[0037] Returning to Figure 1, the support means 6a, 6b, 6c are aligned according to a positioning pattern of said shells flat on the plate so as to press each of the shells of said shells of a lower packaging . In this example where the tray is rectangular, ribs 8 form rows for arranging the shells and the support means are made under the form of a continuous tongue are parallel to the ribs. Other patterns can however be chosen for the ribs depending on the shape of the tray.

[0038] Different configurations are possible for the support means and FIG. 4A shows support means 6b produced by cutting/folding a tongue 61 of material suitable for producing spring strips which will be fixed under the plate, the FIG. 4b represents a support means common to several shells made from a folded tongue 62 which will also be fixed under the plate, for example by gluing, and FIG. 4C represents support means in the form of bosses 6c formed directly in the bottom of the board. The packaging can be completed with a lid 40 shown in Figure 2B so as to keep closed the shells of the shellfish placed in the upper packaging of a stack of said packaging, said packaging of the stack can then be strapped. The stack of packaging can also be surrounded by a film which, in particular in the configuration of figure 2B, will press on the shells of the upper packaging of the stack.

The invention is not limited to the examples described above, only by way of example, but it encompasses all the variants that a person skilled in the art may consider in the context of the protection sought.
