PACKAGE

Abrégé anglais

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.

Revendications

CLAIMS:
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.
