Abstract

ABSTRACT
A number of inner packages are formed into a unit and wrapped in an outer package. The combination of the inner and outer packages allows the package to hold its shape the outer package is opened. The outer package is formed by wrapping the inner package unit in a tubular outer wrap, and sealing the top and bottom surfaces. The outer wrap, or at least the material for the top and bottom panels of the outer package, is made of a contractible or heat shrinkable flexible plastic film which is contracted or heat shrunk to maintain and hold the inner package unit in a tightly packed condition.
Deformation of the outer package is more effectively prevented and makes the outer package easy to handle.
An opening in the outer package is formed by perforation lines in two side panels and a top or bottom panel. The perforation lines may extend the entire height of the outer package. The panel sections between these perforation lines form dust flaps after opening. The outer package is opened and the inner packages are removed individually.

Claims (19)

1. A package comprising a plurality of inner packages formed into a unit, said unit of inner packages being tightly packed in an outer package, said outer package completely enclosing said unit of inner packages, said outer package comprising a tubular outer wrap forming side panels, and sealed top and bottom panels, and lines of perforations that extend across one of said top or bottom panels and into a pair of opposed side panels, said lines of perforations when broken defining both an opening in said outer package and a dust flap comprising the side panel between said opposed side panels and side flanges on said latter side panel.

2. The package of claim 1 in which said lines of perforations are adjacent the side edges of said side panel between said opposed side panels.

3. The package of claim 1 in which said lines of perforations extend the height of said opposed side panels.

4. The package of claim 1 in which said lines of perforations are a pair of parallel lines of perforations that define at least one tear strip.

5. The package of claim 4 in which said lines of perforations have a starting point located centrally of said one of said top or bottom panels.

6. The package of claim 1 in which said line of perforations define a starting point in said one of said top or bottom panels.

7. The package of claim 1 in which said outer package being made of a flexible plastic film, and at least the portions of said film forming said top and bottom panels being of a heat-shrinkable film whereby said unit of inner packages is tightly held when said film is heat shrunk.

8. A package comprising a plurality of inner packages formed into a unit, said unit of inner packages being tightly packed in an outer package, said outer package completely enclosing said unit of inner packages, said outer package comprising a tubular outer wrap forming side panels, and sealed top and bottom panels, and lines of perforations that extend across one of said top or bottom panels and into a pair of opposed side panels, said lines of perforations when broken defining both an opening in said outer package and a dust flap comprising the side panel between said opposed side panels and side flanges on said latter side panel, said lines of perforations being adjacent the side edges of said side panel between said opposed side panels.
said line of perforations defining a starting point in said one of said top or bottom panels.

9. The package of claim 8 in which said lines of perforations extend the height of said opposed side panels.

10. The package of claim 8 in which said outer package being made of a flexible plastic film, and at least the portions of said film forming said top and bottom panels being of a heat-shrinkable film whereby said unit of inner packages is tightly held when said film is heat shrunk.

11. The package of claim 8 in which said lines of perforations are a pair of parallel lines of perforations that define at least one tear strip.

12. The package of claim 11 in which said outer package being made of a flexible plastic film, and at least the portions of said film forming said top and bottom panels being of a heat-shrinkable film whereby said unit of inner packages is tightly held when said film is heat shrunk.

13. A package comprising a plurality of inner packages formed into a unit, said unit of inner packages being tightly packed in an outer package, said outer package completely enclosing said unit of inner packages, said outer package comprising a tubular outer wrap forming side panels, and sealed top and bottom panels, and said outer package being made of a flexible plastic film, and at least the portions of said film forming said top and bottom panels being of a heat-shrinkable film whereby said unit of inner packages is tightly held when said film is heat shrunk.

14. A package comprising a plurality of inner packages formed into a unit, a lid panel placed on one end of said unit as a part of said unit, a handle attached to the outer face of said lid panel, said unit of inner packages and said lid panel being tightly packed in an outer package, said outer package and said lid panel completely enclosing said unit of inner packages, said outer package comprising a tubular outer wrap forming side panels, a sealed bottom panel, and upper flanges attached to said lid panel.

15. The package of claim 14 in which said outer package being made of a flexible plastic film, and at least the portions of said film forming said bottom panel and said upper flanges being of a heat-shrinkable film whereby said unit of inner packages is tightly held when said film is heat shrunk.

16. The package of claim 14 in which said upper flanges are attached to the edges of the outer face of said lid panel and said handle is in a central opening formed by said flanges.

17. The package of claim 16 in which said outer package being made of a flexible plastic film, and at least the portions of said film forming said bottom panel and said upper flanges being of a heat-shrinkable film whereby said unit of inner packages is tightly held when said film is heat shrunk.

18. The package of claim 14 in which said lid panel has edge flanges which are superposed over the inner package adjacent said lid panel.

19. The package of claim 18 in which said outer package being made of a flexible plastic film, and at least the portions of said film forming said bottom panel and said upper flanges being of a heat-shrinkable film whereby said unit of inner packages is tightly held when said film is heat shrunk.
