A packing (1) for e.g. meat consists of a tray (2), which is produced of a relatively rigid plastic foil, and a closure (3) of a relatively flexible plastic foil. The tray (2) has a bottom (4), a side wall (5) and a rim (6). The foil of the closure (3) is heat sealed on the rim (6) of the tray (2) when the tray (2) is filled with the product to be packed. For easily being able to open the packing the foil of the tray is formed with a point (13) situated at the closure plane for penetrating the foil of the closure (3). When the foil (3) initially has been penetrated it is easy to remove by inserting, by way of example, a finger through the formed opening in the foil (3) and tearing this up. The penetrating point (13) is surrounded of a ringformed depression (14) in the foil having an outer wall (15), which is merging into the remaining tray (2), an inner wall (16), which is merging into the penetrating point (13), and a bottom (17), which is connecting the two walls (15; 16). By a pressure with a finger on the underside of the bottom (17) of the depression (14), the depression (14) is deformed by which the point (13) is driven through the foil of the closure (3).

Un emballage (1), destiné par exemple à la viande, comporte une barquette (2) produite avec une feuille de plastique relativement rigide, et une fermeture (3) constituée d'une feuille de plastique relativement souple. Cette barquette (2) comprend un fond (4), une paroi latérale (5) et un rebord (6). La feuille de fermeture (3) est thermosoudée sur le rebord de la barquette une fois que celle-ci est garnie du produit à emballer. Pour faciliter l'ouverture de cet emballage, la feuille de barquette comporte une pointe (13) située sur le plan de fermeture et destinée à percer la feuille de fermeture (3). Une fois celle-ci percée, il est facile de la retirer, avec un doigt qui peut la déchirer par cette ouverture par exemple. Cette pointe de perçage (13) est entourée d'un creux annulaire (14), ménagé dans la feuille, doté d'une paroi externe (15), qui s'escamote dans l'épaisseur de cette barquette (2), d'une paroi interne (16), qui correspond à sa hauteur, et d'une base (17) qui relie ces deux parois (15, 16). En appuyant avec un doigt sous cette base (17) du creux (14), celui-ci se déforme, ce qui fait passer la pointe (13) au travers de la feuille de fermeture (3).
