PACKAGING FOR FOOD PRODUCTS, PARTICULARLY FOR CHEESES.

The invention relates to a packaging for food products, and more specifically intended for cheeses.

To date, there are different types of packaging for cheese (s), making it possible cumulatively to ensure their conservation for a fixed period, while allowing presentation or display of the product by the consumer, in particular by the use of '' a transparent material, such as plastic.

For example, in document FR-A-2 773 137, a package of the type in question has been described, forming a cheese bell, consisting respectively of a base receiving the cheese, surmounted by a bell made of transparent material, capable of s '' assemble reversibly at the base. The bell is also pierced with through holes, intended to allow ventilation of the cheese, and therefore its conservation for the time necessary for its consumption.

However, among the different types of packaging available, there are none likely to have the properties set out above, and as a corollary, to be provided with tamper-evident means or at least to witness the opening of the container. 'packaging.

The object of the invention is therefore to propose a packaging for food products, and in particular for cheeses, capable at the same time of allowing the storage of the cheese, its presentation or display by the consumer before the opening of the packaging. , and also to be provided with means indicating to said consumer the inviolability of the packaging in question.

This packaging for food products, and in particular for cheeses, comprises: - a base of substantially flat shape, intended to receive said food products; - A bell, the lower part or base of which is reversibly adaptable on the base, and in particular on a bead or groove formed at the periphery of said base, said base being further provided with means for retaining the bell, aimed at s '' object to removing it from the base.

 According to the invention, these retention means are constituted by a plurality of linear projections extending at the level of the insertion zone of the bell on the base, and intended to cooperate with complementary through-holes formed at the level of the base. of the bell, part of the supports of said lights must necessarily be broken and at least partially detached from the bell, in order to allow the opening of the packaging, said supports also acting as a tamper-evident witness.

According to a characteristic of the invention, the means for retaining the base are positioned substantially in opposite pairs in pairs with respect to each other, so as to prohibit any opening of the packaging, and in particular any separation from the bell outside the base without having previously broken or partially de-polarized at least one of the means for retaining the bell relative to the base.

The means of retaining the bell acting as a tamper-evident witness are secured thereto by means of breakable bridges, in particular from molding.

According to another characteristic of the invention, part of the retention means integral with the base, intended to allow the reversible opening and reclosing of the bell on the base, therefore after first opening of the packaging, are positioned vertically through a light, formed within the base, so as to give said means a certain elasticity, to allow engagement and disengagement of the bell from the base.

According to another characteristic of the invention, the free edge of the reversible retention means of the bell on the base has a clipping zone, inclined relative to the horizontal, and intended to allow the insertion of the bell on the base by pressing and sliding the base of the bell over this clipping zone, after placing the food product to be packaged on the base.

Advantageously, the bell is made of plastic, and in particular of transparent plastic, so as to allow viewing of the contents of the packaging.

 The manner in which the invention can be implemented and the advantages which ensue therefrom will emerge more clearly from the embodiment which follows, given by way of non-limiting example, in support of the appended figures.

Figure 1 is a schematic perspective representation of the packaging according to the invention.

Figure 2 is a view similar to Figure 1, but shown in exploded view.

Figure 3 is a schematic representation of the package, seen from above.

Figure 4 is a partial schematic representation in section of the package.

Figure 5 is a schematic representation in section of a detail of the cooperation zone of the retention means acting as a witness to the inviolability of the bell on the base.

Figure 6 is a view similar to Figure 5, but showing the cooperation between the bell and the base at the reversible retention means.

There is therefore shown in relation to Figure 1, a perspective view of the package (1) according to the invention. Basically, it is polyhedral, and in this case slightly frustoconical pyramidal, and has a base (2) surmounted by a bell (3).

Advantageously, the bell (3) and the base (2) are made of plastic, in particular by injection.

In addition, and in order to allow the contents of the packaging to be viewed by the potential consumer, the bell (3) is made of a transparent material.

The bell (3) can also receive on its upper face, and in addition on two of its lateral faces, a label indicating the brand, and / or the nature and / or regulatory information relating to the product contained in the packaging. This label can be attached by gluing, but can also be deposited inside the bell according to the technique of deposition in the mold during injection (inmold labeling). It can, in addition, be replaced by a decoration according to all the decoration methods known to date.

<Desc / Clms Page number 4>

 As can be seen in Figures 1 and 2, the bell (3) fits at its base (4) on the base (2), the latter being provided, in particular by injection to this effect, a bead or peripheral groove (5) of complementary shape.

In addition, and in order to promote this cooperation between the bell (3) and the base (2), this is provided at these four angles, projections directed upwards (7), also resulting from molding, making it possible to promote the casing of the bell at the base, in particular during successive openings and closings of the packaging, after first use.

In parallel, and in accordance with the invention, the closure of the bell (3) on the base (2) is obtained by the cooperation of retention means (8) and (9) formed at the level of the bead or peripheral groove of the base ( 2) with complementary through-holes, respectively (10) and (11), formed at the level of the bell, and more precisely at the level of the base (4) of the bell.

These retention means (8) and (9) are in the form of horizontal linear projections, extending at the level of the bead or peripheral groove of said base. They are in particular oriented perpendicular to the direction of fitting, or withdrawal of the bell relative to the base. These retention means also come from molding and operate in pairs two to two opposite, as can be seen in Figures 3 and 4 for example.

In fact, two of the retention means (8), more specifically dedicated to the reversible casing of the bell on the base, are each located directly above a through light (12), also provided at the level of the base, substantially in the same plane as said means, so as to give them a certain elasticity, in order to favor their clipping function during successive interlockings and withdrawals of the bell from the base (2), obviously after first opening of packaging.

As a corollary, the bell (3) has at its base through holes (10) cooperating with these retention means (8). Two of these lights, also arranged in opposition, cooperate with the reversible fixing means, in particular the retention means (8), in order to allow the successive openings and closings of the packaging.

<Desc / Clms Page number 5>

 On the other hand, the two other through holes (11) of the bell (3), intended to cooperate with the retention means (9) of the base, are provided at the level of lugs (13), forming a continuity with the base (4 ) from the bell, but nevertheless liable to be separated from them when in particular the first opening of the packaging. In fact, these tabs (13) are secured to the base (4) of the bell by means of breakable bridges (16,17), respectively formed at the beginning of the base (4) and on the other hand, at the level of the lower lip (14) emanating therefrom in a direction substantially parallel to the plane of the base or substantially perpendicular to the base, lip intended to allow nesting and more specifically, the cooperation between the base retention means and bell lights.

Thus, the base retention means are provided with a support zone (15), defining with respect to the general plane of the base an insertion zone at the level of which the lip (14) from the base slides. (4) of the bell (3).

Due to the diametrically opposite position of the retention means (9) of the base, the bell can be removed from it only after breakage, and at the very least separation of the tabs (13) from the bell. This break or this separation is made possible by the use of breakable bridges (16,17) above.

Thus, it suffices to exert an upward pull on the tabs (13) in question to firstly result in the rupture of the breakable bridges (17) situated at the level of the lip (14), then, as a corollary, breakable bridges (16) located at the base. However, the breaking of the breakable bridges (16) is not imperative to allow the first opening of the packaging according to the invention. Indeed, these can act as a hinge, with respect to which the tabs (13) can be rotated to disengage the retention means (9) from the base.

In doing so, by playing on the elasticity of the plastic material used, elasticity optimized by the use of the lights (12) formed at the level of the base, it is possible to remove the bell, and thus have access to the content. of the packaging. These tabs (13) therefore constitute an effective means of proof of the inviolability of the packaging.

Advantageously, the whole of the bell, that is to say the bell, its base and the legs acting as a tamper-evident witness, constitutes a one-piece assembly, resulting from molding.

<Desc / Clms Page number 6>

As can be seen in detail in Figures 5 and 6, the retention means (8, 9) of the base have a lip (18) inclined relative to the horizontal, making it possible to constitute the clipping zones.

In fact, this inclined lip (18) is intended to allow the placement of the bell on the base, obviously after positioning the cheese or the food product on said base.

By playing respectively on the elasticity of the plastic material constituting the lip of the retention means of the base, and the relative flexibility of the breakable bridges, it is possible to exert a simultaneous pressure at the level of said opposite retention means on said lip, until the lower lip (14) of the base (4) of the bell (3) swings into the insertion zone at the level of which it becomes trapped, unless breaking, as already said, the breakable bridges legs with which the base of the bell is provided.

We understand in fact all the interest of the packaging according to the invention, insofar as on the one hand, it makes it possible to clearly show the inviolability of the packaging, and on the other hand, once the retracted inviolability means, nevertheless allows a plurality of openings and closings of the packaging, in particular by clipping the bell on the base by the use of reversible securing means.

In doing so, the contents of the package can be kept substantially sheltered as it is consumed, thus allowing it to be preserved for the duration of its progressive consumption.
