Embodiment Construction

[0245] tray

[0246] 1 generally indicates a tray containing a product P, for example a product of the food type. The figures show where a tray 1 holds only one product P (see for example Figure 12 ) case; however, the possibility of accommodating multiple products P in the tray is not excluded.

[0247] As can be seen in the figures, the tray 1 comprises a base 2 of sheet material, generated in a plane between mainly generated inner and outer surfaces, the distance of which defines the thickness of the base 2 . The figures show, in a non-limitative manner, a base 2 having a polygonal shape, in particular a square base 2 . However, the possibility of making the base 2 with a rectangular, rhombus, triangular, oval, circular, semicircular shape is not excluded.

[0248] As can be seen from the figures, the lateral walls 3 emerging from the base 2 are also made of sheet material, generated between the main generating inner and outer surfaces, the distance of which defines the...

Abstract

The present invention refers to a tray for containing a product (P). The tray (1) comprises a base (2), a lateral wall (3) emerging from the base (2) to define a containing seat adapted to receive theproduct (P). The lateral wall (3) comprises at least one movable portion (7) configurable between a first stable position, wherein the movable portion (7) is placed in continuity with respect to thelateral wall (3), and a second stable position, wherein the movable portion (7) protrudes from the lateral wall (3) and defines an access (8) passing through the lateral wall (3) itself. Moreover, thepresent invention refers to a process and an associated apparatus of making said tray (1). Further, the present invention refers to a vacuum package using the above described tray and to a plastic film sealingly applied on the tray and closing the access (8), and also to a process and a packaging apparatus for making the package.

Description

technical field [0001] The present invention relates to trays and associated packages, in particular trays and associated packages for containing food-type products. Furthermore, the invention relates to a process and associated equipment for making said tray and said package. Background technique [0002] Apparatus and associated methods for vacuum packaging products are known in the art of packaging. In the packaging process, it is known to make packages by means of plastic film in order to vacuum seal foodstuffs such as, for example, meat and fish to be frozen, cheese, processed meats, ready-to-eat meals and similar foodstuffs. Vacuum packages of this type closed by a plastic film are described, for example, in the following patent documents: FR1258357, FR1286018, AU3491504, USRE30009, US3574642, US3681092, US3713849, US4055672 and US5346735. [0003] The vacuum packaging process is basically a thermoforming process comprising the step of providing the product (food) in...
