Barrier bag assembly for aerosol container

Claim 2

A plastic bag for an aerosol container comprising a generally cylindrical collapsible body and top and bottom end members, and means on said bottom member for resisting collapse of the bottom member upon the imposition of pressure on the body and bottom member, said body having portions adapted to fold in radially and the top end member of said bag being generally frusto conical and having an upper neck portion and gradually becoming thinner toward its juncture with the upper end of the body portion and being collapsible therewith inwardly.

Claim 3

A plastic bag for an aerosol container comprising a generally cylindrical collapsible body and top and bottom end members, and means on said bottom member for resisting collapse of the bottom member upon the imposition of pressure on the body and bottom member, said body having portions adapted to fold in radially and said bottom member being formed of essentially two portions one of which slopes downwardly at a steeper angle than the other and said steeper angled portion being of thinner section than the other and upon exhaustion of product from the bag being adapted to form a generally triangular segment overlapping the other bottom portion and one edge of said segment forming a lower edge of the other portion and said segment having two other sides edges forming a juncture with lower ends of said portions of the body wall folded in by the pressure as product is exhausted from the bag.

Claim 4

A plastic bag for an aerosol container comprising a generally cylindrical collapsible body and top and bottom end members, and means on said bottom member for resisting collapse of the bottom member upon the imposition of pressure on the body and bottom member, said body having portions adapted to fold in radially and said bottom member being formed of essentially two portions one of which slopes downwardly at a steeper angle than the other and said steeper angled portion being of thinner section than the other and upon exhaustion of product from the bag being adapted to form a generally triangular segment overlapping the other bottom portion and one edge of said segment forming a lower edge of the other portion and said segment having two other sides edges forming a juncture with lower ends of said portions of the body wall folded in by the pressure as product is exhausted from the bag.

Claim 5

A plastic bag for an aerosol container comprising a generally cylindrical collapsible body and top and bottom end members, and means on said bottom member for resisting collapse of the bottom member upon the imposition of pressure on the body and bottom member, said body having portions adapted to fold in radially and said bottom having two segments joined in a downwardly directed apex, one segment being dimensionally smaller than the other segment and being foldable thereover and affecting folding of adjacent sections of the side wall of the body portion inwardly of the bag, and the side edges of the larger bottom segment controlling inward deflection of portions of the body flanking said sections to a position embracing the folded sections.

Claim 6

A plastic bag for an aerosol container comprising a generally cylindrical collapsible body and top and bottom end members, and means on said bottom member for resisting collapse of the bottom member upon the imposition of pressure on the body and bottom member, said body having portions adapted to fold in radially and said bottom having two segments joined in a downwardly directed apex, one segment being dimensionally smaller than the other segment and being foldable thereover and affecting folding of adjacent sections of the side wall of the body portion inwardly of the bag, and the side edges of the larger bottom segment controlling inward deflection of portions of the body flanking said sections to a position embracing the folded sections.

Claim 7

A plastic bag for an aerosol container comprising a generally cylindrical collapsible body and top and bottom end members, and means on said bottom member for resisting collapse of the bottom member upon the imposition of pressure on the body and bottom member, said body having portions adapted to fold in radially and a spine integrally formed on the bottom of said bag.

Claim 8

A plastic bag for an aerosol container comprising a generally cylindrical collapsible body and top and bottom end members, and means on said bottom member for resisting collapse of the bottom member upon the imposition of pressure on the body and bottom member, said body having portions adapted to fold in radially and a spine integrally formed on the bottom of said bag.

Claim 9

The invention according to claim 4 and said spine being in the form of a fin extending flatwise axially of the container.

Claim 10

The invention according to claim 5 and said spine being located solely upon said apex and depending from said bottom.

Claim 11

The invention according to claim 4 and said bottom having angularly related portions joined in an apex and said spine bisecting the apex.

Claim 12

The invention according to claim 4 and said body portion being foldable into a generally Y-shaped configuration.

Claim 13

The invention according to claim 4 and said body portion being foldable into a generally X-shaped configuration.
