This substantially rigid product packaging shell which defines a volume (3) for the at least partial housing of the product (7), having an opening that is closed using a flexible cover (6), is characterised in that the shell is produced in at least two parts (1a, 1b), which parts can be easily separated, at least partially, and which can come apart on the non-cover (6) side by pivoting in the area (2) next to the shell opening (4).

Description

Coque d'emballage à ouverture facilitée Easy opening packaging shell
L'invention concerne une coque d'emballage sensiblement rigide d'un produit, définissant un volume de logement au moins partiel du produit, et fermée par un couvercle..The invention relates to a substantially rigid packaging shell for a product, defining an at least partial housing volume of the product, and closed by a cover.
De telles coques sont connues pour l'emballage des fromages, par exemple par les documents EP 0952093, FR 2 773 137 ou FR 2 786 471. Dans ces coques, le couvercle est sensiblement rigide et peut se détacher de la coque pour accéder au produit. Dans d'autres emballages connus, le couvercle est un opercule souple qu'on détache de la coque. Dans l'un et l'autre cas, l'accès au produit dans la coque n'est pas toujours satisfaisant, surtout si, par exemple, le produit a tendance à coller aux parois de la coque ; une fois le couvercle enlevé, il reste à extraire le produit de la coque. Dans le cas d'un produit alimentaire, cette extraction n'est pas nécessairement très hygiénique ou peut salir les doigts. Le document US 3521805 montre une coque d'emballage fermée par une pellicule et dont la forme fait qu'en le pliant à l'aide des doigts, on rompt une partie en forme de goulot de la coque, ce qui permet de distribuer le produit lequel est nécessairement sous forme fluide (poudre, liquide ou pâte). Les documents DE 7607897U, US 4266667 et US 3075639 montre des emballages de type "blisters" plus ou moins articulés, destiné à contenir des produits non alimentaires tels que des crayons ou des aiguilles stériles, mais inadapté au problème de produits alimentaires tel que le fromage qu'on souhaite ne pas toucher avec les doigts.Such shells are known for packaging cheeses, for example by documents EP 0952093, FR 2 773 137 or FR 2 786 471. In these shells, the cover is substantially rigid and can be detached from the shell to access the product. . In other known packages, the cover is a flexible seal that is detached from the shell. In both cases, access to the product in the shell is not always satisfactory, especially if, for example, the product tends to stick to the walls of the shell; once the cover is removed, it remains to extract the product from the shell. In the case of a food product, this extraction is not necessarily very hygienic or can dirty the fingers. Document US 3521805 shows a packaging shell closed by a film and whose shape means that by folding it with the fingers, a neck-shaped portion of the shell is broken, which makes it possible to distribute the product. which is necessarily in fluid form (powder, liquid or paste). Documents DE 7607897U, US 4266667 and US 3075639 show more or less articulated blister type packaging intended to contain non-food products such as pencils or sterile needles, but unsuitable for the problem of food products such as cheese that you don't want to touch with your fingers.
Le but de l'invention est de proposer un emballage du type défini plus haut qui permette un accès facilité au produit contenu dans la coque, sans avoir à toucher ledit produit, notamment pour un produit solide tel que le fromage. L'invention atteint son but grâce à une coque d'emballage sensiblement rigide d'un produit, définissant un volume de logement au moins partiel du produit présentant une ouverture fermée par un couvercle souple disposé sur une région marginale annulaire de la coque, la coque étant réalisée en au moins deux parties réunies par une zone d'ouverture facile, facilement séparables au moins partiellement et qui peuvent s'écarter du côté opposé au couvercle en s'articulant sur la région voisine de l'ouverture de la coque, caractérisée en ce que la coque est sensiblement hémisphérique et la zone est une zone équatoriale. De la sorte, l'utilisateur accède au produit, non plus en ouvrant le couvercle (lequel en revanche a pu servir au remplissage du produit dans la coque) mais en séparant la coque en ses au moins deux parties articulées et en l'ouvrant, ce qui dégage le produit logé dans la coque et reposant toujours en partie sur le couvercle.The object of the invention is to provide a packaging of the type defined above which allows easy access to the product contained in the shell, without having to touch said product, in particular for a solid product such as cheese. The invention achieves its object thanks to a substantially rigid packaging shell of a product, defining an at least partial housing volume of the product having an opening closed by a flexible cover disposed on an annular marginal region of the shell, the shell being made up of at least two parts joined together by an easy opening zone, easily at least partially separable and which can deviate on the side opposite the cover, hinging on the region close to the opening of the shell, characterized in that the shell is substantially hemispherical and the area is an equatorial area. In this way, the user accesses the product, no longer by opening the cover (which on the other hand could have been used for filling the product in the shell) but by separating the shell into its at least two articulated parts and by opening it, which releases the product housed in the shell and still partially resting on the cover.
Comme le couvercle est souple (au moins localement dans l'axe de l'articulation) , il ne s'oppose pas à l'articulation des deux parties de coque. Avantageusement, la zone d'ouverture facile est une zone fragilisée, par exemple amincie, ou une zone ouverte recouverte d'une bande arrachable.As the cover is flexible (at least locally in the axis of the articulation), it does not oppose the articulation of the two shell parts. Advantageously, the easy opening zone is a weakened zone, for example thinned, or an open zone covered with a removable strip.
L'invention s'applique de préférence au conditionnement des produits alimentaires, tels que du fromage ou des salaisons en portions individuelles qu'il est facile de manger sans se salir.The invention preferably applies to the packaging of food products, such as cheese or cured meats in individual portions which it is easy to eat without getting dirty.
D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui va suivre, en référence aux dessins annexés sur lesquels :Other characteristics and advantages of the invention will emerge on reading the description which follows, with reference to the appended drawings in which:
-la figure 1 est une vue en coupe schématique d'une coque conforme à l'invention avant son remplissage et sa fermeture,FIG. 1 is a schematic sectional view of a shell according to the invention before it is filled and closed,
-la figure 2 est une vue en coupe schématique de la même coque après remplissage et fermeture par un opercule,FIG. 2 is a schematic sectional view of the same shell after filling and closing with a cover,
-la figure 3 est une vue en perspective de la coque telle qu'elle se présente au consommateur, -la figure 4 est une vue en perspective de la même coque après début d'arrachage de la languette d'ouverture,FIG. 3 is a perspective view of the shell as it appears to the consumer, FIG. 4 is a perspective view of the same shell after the tear-off of the opening tongue,
-la figure 5 est une vue en perspective de la même coque après ouverture et pivotement des demi-coques.FIG. 5 is a perspective view of the same shell after opening and pivoting of the half-shells.
La coque sensiblement hémisphérique 1 comprend une bordure annulaire plane 2 et est réalisée par exemple en matière plastique transparente. La coque forme un logement 3, destiné à être fermé au niveau de son ouverture circulaire 4. Selon une technique connue, le produit est introduit (flèche 5) par l'ouverture dans la coque renversée 1, puis un opercule 6, par exemple en complexe métal-plastique, est amené sur la bordure 2 pour y être scellé et fermer ainsi de manière hermétique la coque 1 avec son produit 7.The substantially hemispherical shell 1 comprises a flat annular border 2 and is made for example of transparent plastic. The shell forms a housing 3, intended to be closed at its circular opening 4. According to a known technique, the product is introduced (arrow 5) through the opening in the inverted shell 1, then a cover 6, for example in metal-plastic complex, is brought to the border 2 to be sealed there and thus seal the shell 1 with its product 7.
La coque 1 comporte une zone équatoriale médiane ouverte 8 séparant la coque en deux demi-coques symétriques la, lb réunies par la bordure 2. La zone 8 est recouverte extérieurement par une bande d'ouverture 9 dont au moins une extrémité 10 forme une languette qui peut être saisie manuellement. La bande 9 dépasse des deux côtés (ou d'un seul côté) de la zone ouverte 8 pour être solidarisée à chacune des deux demi- coques la, lb. La bande 8 peut être mise en place au moment du moulage de la coque, selon les techniques connues de pose d'étiquettes dans les moules. Lorsqu'elle est en place, elle ferme de façon étanche la zone 8 et permet donc d'effectuer le remplissage du produit 7.The shell 1 comprises an open central equatorial zone 8 separating the shell into two symmetrical half-shells la, lb joined by the edge 2. The zone 8 is covered externally by an opening strip 9 of which at least one end 10 forms a tongue which can be entered manually. The strip 9 protrudes from two sides (or only one side) of the open area 8 to be secured to each of the two half-shells la, lb. The strip 8 can be put in place at the time of the molding of the shell, according to known techniques for applying labels in the molds. When it is in place, it tightly closes the zone 8 and therefore makes it possible to fill the product 7.
Pour accéder au produit, le consommateur saisit la languette 10 et la tire, ce qui décolle la bande 9 et dégage la zone ouverte 8. Les deux coques ne sont plus réunies que par la bordure 2 et l'opercule souple 6. Le consommateur peut alors, d'une seule main s'il le veut, faire pivoter les deux demi-coques la, lb sensiblement autour du diamètre 11 situé à l'intersection du plan de la zone équatoriale 8 et de la bordure 2, de manière à faire apparaître le produit 7 dont le fond est appuyé sur l'opercule 6. L'articulation des deux demi-coques est facile dans la mesure où l'opercule est souple et ne gêne pas le mouvement et où la bordure 2, quoique plus rigide, est relativement étroite. On peut d'ailleurs prévoir au besoin une ligne d'affaiblissement, par exemple un amincissement, dans la bordure 2 au niveau du diamètre 11. On peut aussi prévoir au lieu d'un opercule entièrement souple un couvercle rigide mais comprenant une charnière au niveau du diamètre 11 de manière à permettre l'articulation.To access the product, the consumer grasps the tongue 10 and pulls it, which takes off the strip 9 and releases the open area 8. The two shells are no longer joined except by the edge 2 and the flexible cover 6. The consumer can then, with one hand if desired, rotate the two half-shells la, lb substantially around the diameter 11 located at the intersection of the plane of the equatorial zone 8 and the border 2, so as to make appear the product 7, the bottom of which is supported on the cover 6. The articulation of the two half-shells is easy insofar as the cover is flexible and does not impede movement and where the edge 2, although more rigid, is relatively narrow. It is also possible to provide, if necessary, a line of weakness, for example a thinning, in the border 2 at the level of the diameter 11. It is also possible, instead of a fully flexible cover, to provide a rigid cover but comprising a hinge at the level of diameter 11 so as to allow articulation.
Plutôt qu'une bande 9 se décollant entièrement, on peut prévoir une bande intégrant un fil d'ouverture qui la déchire et permet la désolidarisation des deux demi-coques. On peut aussi prévoir tout autre système permettant cette désolidarisation des coques, comme par exemple une zone équatoriale affaiblie se déchirant facilement, on une zone équatoriale formée entre deux lignes d'affaiblissement et formant elle-même une languette intégrale déchirable. Rather than a strip 9 peeling off entirely, it is possible to provide a strip incorporating an opening wire which tears it apart and allows the two half-shells to be separated. One can also provide any other system allowing this separation of the shells, such as for example a weakened equatorial zone which is easily torn, an equatorial zone formed between two weakening lines and itself forming an integral tear-away tab.
