Abstract

A packaging for wrapping objects, such as hamburgers, tacos and other foodstuff includes a pleated zone which expands when pulled longitudinally, and an unpleated, or straight zone which is used originally to wrap the object. The packaging is easier to use than packaging having only a pleated zone.

Claims

1. A packaging for wrapping an object, said packaging comprising:

a first zone consisting of a pleated sheet having lateral edges and first and second sides, said sheet being folded into successive pleats between said lateral edges, and first and second fixation areas disposed along said sides for fixing said pleats, wherein said first zone may be applied by training said lateral edges at least partially around said object to open said pleats with said first and second sides forming end openings; and

a second zone consisting of a straight sheet and attached on one side to one of said lateral edges of said first zone with said second zone being disposed adjacent to said object when said first zone is applied to said object.

2. The packaging of claim 1 wherein said first zone and second zone are joined end-to-end to form a continuous package sheet.

3. The packaging of claim 1 wherein said second zone is folded over said first zone.

4. The packaging of claim 1 wherein said first and second zones are formed from a continuous paper film.

5. The packaging of claim 1 wherein said first and second are made of the same material.

6. The packaging of claim 1 wherein said first zone is of a relatively thin material and said second zone is made a material stiffer than the material of said first zone.

7. The packaging of claim 1 wherein said first zone is than said second zone.

8. The packaging of claim 1 wherein said first zone is narrower than said second zone.

9. The packaging of claim 1 further comprising a third zone, said third zone being made of a stiffer material than said first and second zone, wherein said third zone is disposed peripherally around said object for protection when said packaging is wrapped around said object.

10. The packing of claim 1 where at least one of said zones consists of a layer of paper covered by a layer of plastic.

11. The packaging of claim 1 wherein said pleats are parallel.

12. A packaging for wrapping an object having a height, said packaging comprising:

a first member consisting of a pleated sheet having lateral edges and first and second sides, said sheet being folded into successive pleats between said lateral edges, and first and second fixation areas disposed along said sides for fixing said pleats, wherein said first member may be applied by training said lateral edges at least partially around said object to open said pleats with said first and second sides forming end openings; and

a second member consisting of a straight sheet with a width substantially equal to said height of said object and attached on one side to one of said lateral edges of said first member, said second member being arranged to protect said object when said second member is trained around said object.

13. The packaging of claim 12 wherein said second member is made of a material stiffer than the material of said first member.

14. The packaging of claim 12 wherein said second member has a length selected to enclose said object.

15. A packaging for wrapping an object, said packaging comprising:

a first member consisting of a pleated sheet having lateral edges and first and second sides, said sheet being folded into successive pleats between said lateral edges, and first and second fixation areas disposed along said sides for fixing said pleats, wherein said first member may be applied by training said lateral edges at least partially around said object to open said pleats with said first and second sides forming end openings; and

a second member consisting of a straight sheet and attached on one side to one of said lateral edges of said first member and extending beyond one of said first and second sides, said second member being arranged to close one of said end openings as said first member is applied to said object.

16. A method of packaging an object, such as foodstuff, comprising the steps of:

providing a packaging including a straight zone connected to a pleated zone, said pleated zone being formed of a sheet having lateral edges and first and second sides, said sheet being folded into successive pleats between said lateral edges, and first and second fixation areas disposed along said sides for fixing said pleats;

placing said object on said straight zone;

wrapping said object at least partially with said straight zone; and

wrapping said object with said pleated zone by training said sheet around said object and partially opening said pleats.
