Abstract

A package includes a support having a base having a product thereon, a peripheral flange surrounding the base and forming at least one gripping tab, and a film engaged with the peripheral flange to define a housing compartment for the product. The support has a first surface and a second surface, with the second surface presenting heat bonding properties to the film that are different from heat bonding properties of the first surface to the film. The gripping tab includes a first portion and a second portion arranged above the first portion. The gripping tab is externally defined by the second surface and includes a peripheral edge which is part of a radially external perimeter of the peripheral flange.

First claim

The invention claimed is:

1. A package comprising:
a support comprising:
a base configured to hold a product, and
a peripheral flange surrounding the base and forming a gripping tab,
wherein the support is formed from a substrate having a first surface and a second surface opposite to the first surface; and

a film engaged with at least part of the peripheral flange, wherein the film and the support define a housing compartment for the product, wherein the film is configured to be partially separated from the support when the package is opened to allow access to the housing compartment;
wherein the gripping tab comprises:
a first portion of the support that includes a first part of the first surface and a first part of the second surface;
a second portion of the support that includes carrying a second part of the first surface and a second part of the second surface, wherein the second portion is in overlapping position above the first portion so that the first part of the first surface in the first portion faces the second part of the first surface in the second portion, and wherein the second part of the second surface of the first portion and the second part of the second surface of the second portion form opposite external sides of the gripping tab; and
a peripheral edge that is part of a radially-external perimeter of the peripheral flange;

wherein, when the package is closed, the film forms a flap configured to be grabbed by a user to at least partially separate the film from the support to at least partially open the package and allow access to the housing compartment;
wherein, when the package is closed, the flap is parallel to the peripheral flange and the peripheral edge of the gripping tab is part of the radially external perimeter of the peripheral flange; and
wherein the flap has a free portion that does not cover the gripping tab or the peripheral flange, wherein the flap extends above an indent in the perimeter of the peripheral flange.

2. The package of claim 1 , wherein the flap is an integral part of the film and is made exclusively from a portion of the film.

3. The package of claim 1 , wherein the flap does not include any part of the support.

4. The package of claim 1 , wherein, before the package is open:
the film and the support prevent access to the housing compartment; and
a flap of the film is at least partially raised from the gripping tab so that the gripping tab is operable by a user.

5. The package of claim 4 , wherein, before the package is open, the flap is raised from the gripping tab, and wherein the raised flap is made exclusively from a portion of the film.

6. The package of claim 5 , wherein the raised flap does not include any part or material of the support.

7. The package according to claim 1 , wherein the free portion of the flap has the same shape of the gripping tab.

8. The package of claim 1 , wherein the peripheral flange comprises a cutout portion adjacent to the gripping tab and has a shape of the second portion, wherein the cutout portion defines an indent in the external perimeter of the peripheral flange having the shape of the second portion.

9. The package of claim 1 , wherein the peripheral flange comprises a cutout portion that is adjacent to the gripping tab and has a shape of the second portion.

10. The package of claim 1 , wherein the external perimeter of the peripheral flange has a convex shape when viewed from above the package.

11. The package according to claim 8 , wherein a portion of the external perimeter of the peripheral flange outside of the indent has a convex shape when viewed from above the package.

12. The package of claim 1 , wherein the package is configured to be completely opened by a user completely removing the film from the support without removing any part of the support.

13. The package of claim 1 , wherein the first and second surfaces are heat bonded to the film, and wherein heat bonding properties of the film to the second surface are different from heat bonding properties of the film to the first surface.

14. The package of claim 1 , wherein the second portion is connected to the first portion.

15. The package of claim 1 , wherein the peripheral edge of the gripping tab is formed by overlapping peripheral edges of the first portion and of the second portion.

16. The package of claim 1 , wherein:
the package is closed with the film gas-tightly bonded to an annular bonding area of the peripheral flange to seal the housing compartment from an outer environment external to the housing compartment; and
the annular bonding area is a part of the first surface and peripherally and entirely surrounds the housing compartment.

17. The package of claim 1 , wherein the second portion is connected to the first portion at a folding line and the second portion is folded above the first portion around the folding line.
