Definitions

  • the present invention generally relates to a container for food use in particular, and essentially relates to a tray of the type comprising a body element provided with an upper rim of non-circular shape and a cover element having a groove intended to receive at its bottom. said ledge.
  • the invention finds particular application in the food industry and in particular for the preparation of vacuum packed dishes intended to be reheated in their packaging before consumption.
  • a additional plastic film forming a seal placed between the container lid and its body.
  • Such a film in order to seal the container, is generally made of a complex multilayer plastic material, and requires an additional heat-sealing or self-adhesive operation on the body of the container.
  • the object of the present invention is to solve the aforementioned problems, by proposing a container of the aforementioned type, of simpler design which makes it possible to package food products in a perfectly sealed manner, which can be easily opened without deterioration of the lid and which does not require not an additional seal.
  • the solution according to the present invention consists of a container of the type comprising a body element provided with an upper rim of non-circular shape and a cover element having a groove intended to receive at the bottom said rim of said body, and comprising a groove radially external to said groove, projecting under the latter towards the inside of said body and coming into contact with said rim of the body in the closed position of the container, characterized in that the groove has a shallower depth in the parts of small radius of curvature, such as the parts forming an angle, than in the lateral parts of the cover of greater radius of curvature, or sensiblemcnt rectilinear.
  • Such a container is perfectly sealed and allows food products to be kept airtight without any risk of deterioration, and can be easily opened without damaging the lid.
  • the depth of the abovementioned groove, in each part of small radius of curvature is a function of the length of the arc forming said part of small radius of curvature, and in each lateral part the depth of the groove is a function of the length of said lateral part.
  • Another object of the present invention is to produce a vacuum packaging of products, in particular food products, which is not deformed by putting under vacuum or under neutral gas. Indeed, when using a thermoformed tray in a flexible material, it is crushed by the vacuum. This results in poor presentation and the impossibility of stacking the trays once filled one above the other.
  • the lid of a container according to the invention comprises a deformable, preformed part, capable of being deformed, during vacuuming, to conform to the profile of the food contained in the container. . This results in a neat and attractive presentation for consumers, the sealing of the tray also ensuring long-term preservation of food.
  • such trays once filled can be easily stacked which saves space advantageously during storage.
  • a tray of substantially parallelepiped shape is shown with a substantially rectangular longitudinal section made of polypropylene.
  • the general principle of the invention is applicable regardless of the shape of the tray, provided that its upper edge is not circular, and whatever the material from which this tray is made.
  • the tray which has been produced and which will be described here is made of polypropylene, and can withstand temperatures of the order of 120 to 130 ° C. without damage.
  • the food products contained in such trays can be quickly cooked or reheated for example in a microwave oven, and can be eaten immediately after cooking.
  • a tray 1 according to the invention comprises a body 2 provided with an upper rim 3 of non-circular shape and a cover 4 having on its internal surface a groove 5 of cross section substantially U-shaped intended to receive at its bottom the rim 3, also of substantially U-shaped cross section.
  • This rim is connected to the trunk 11 of the body 2 by an angular part 12 intended to come into contact with the bottom of the cover 4 when the container is closed, thus forming a sealing point.
  • the cover 4 includes a groove or groove peripheral 6 radially external to the groove 5 projecting under the latter towards the inside of the container body 2.
  • the groove 6 comes into contact with the rim 3, at the end 9 of the latter, in the closed position of the container. More specifically, the groove 6 comes to bear under the end 9 of the rim 3.
  • the groove 6 has a smaller depth in the parts of small radius of curvature, such as the parts forming an angle A, than in the lateral parts L of the cover, of greater radius of curvature or substantially rectilinear .
  • the invention is in fact based on the discovery that differences in the depth of the groove between the corners and the rest of the periphery of the groove 6 ensure both perfect sealing and the possibility of easily removing the cover without damaging the latter. .
  • the depth of the groove 6 in each part forming an angle A is chosen as a function of the length of the arc forming said part at an angle A.
  • the depth of the groove is all the more important as the length of the arc trained is important.
  • this depth h is on the order of 0.3 to 0.8 mm, and preferably 0.3 to 0.4 mm in the example shown, where the length of the arc A is approximately 35 to 40 mm.
  • the depth of the groove is a function of the length of said side portion. In general, this depth can be of the order of 0.8 to 1.1 mm and in the example shown the depth of the groove in the side parts of greater length (about 150 mm) is 1 , 1 mm while it is about 0.8 mm in the shorter side parts (about 70 mm).
  • a connecting portion of the groove R which has a concave profile followed by a convex profile.
  • each connection portion R is chosen, in particular as a function of the length of the arc formed by the part of associated small radius of curvature A.
  • the greater the depth of the groove in a connection portion the greater the length of the arc formed by the associated angled part A.
  • each connection part extends over a length of approximately 12 to 15 mm.
  • the cover 4 comprises a peripheral end edge 10 plane and substantially horizontal facilitating the gripping of the cover therefore the opening of the closed container.
  • FIGS. 5 to 7 show a particular embodiment of the invention which finds particular application in the packaging of products packed under deep vacuum.
  • the cover comprises a deformable part 8 preformed, capable to be deformed during the evacuation, to match the profile of the food P contained in the container.
  • the deformable part 8 is a convex wall of convex shape in the non-deformed state which can be easily obtained by molding.
  • the tray obtained after filling and evacuating ( Figure 7) has various advantages.
  • these full trays can be easily stacked, hence an appreciable saving of space during storage.
