Abstract
Abstract A plastic container such as a collapsible blood bag or a parenteral solution container may include a flexible sheet member integrally attached to a plastic container and defining lines of tearing weakness for defining and unfolding an elongated sheet member portion, which, in turn, defines a second line of tearing weakness for forming a retaining aperture for receiving a sample tube and the like. Also, the container may have a retention member positioned at each end of the plastic container comprising open, transverse channel means proportioned to receive a length of flexible tubing wound about the ends of said container.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
125 words
In a plastic container, the improvement comprising: a flexible sheet member integrally attached at an edge thereof to said plastic container, said sheet member defining a first line of tearing weakness which extends from a free edge of the sheet member inwardly thereof to terminate at a point of said sheet member which is spaced from the edges thereof, whereby tearing of said first line permits the defining and unfolding of at least one elongated sheet member portion, said elongated sheet member portion defining a second line of tearing weakness, both ends of which are spaced from the edges of said sheet member portion, whereby said second line may be torn open to define a retaining aperture for receiving a sample tube and the like.
Claim 2
Dependent Claim
125 words
In a plastic container, the improvement comprising: a flexible sheet member integrally attached at an edge thereof to said plastic container, said sheet member defining a first line of tearing weakness which extends from a free edge of the sheet member inwardly thereof to terminate at a point of said sheet member which is spaced from the edges thereof, whereby tearing of said first line permits the defining and unfolding of at least one elongated sheet member portion, said elongated sheet member portion defining a second line of tearing weakness, both ends of which are spaced from the edges of said sheet member portion, whereby said second line may be torn open to define a retaining aperture for receiving a sample tube and the like.
Claim 3
Dependent Claim
21 words
The plastic container of claim 1 which has flexible, collapsible walls with sealed access port means positioned at one end thereof.
Claim 4
Dependent Claim
14 words
The plastic container of claim 2 which is blow molded from a tubular parison.
Claim 5
Dependent Claim
89 words
The plastic container of claim 3 in which said first line of tearing weakness defines a tortuous path, whereby tearing of said first line permits the defining and unfolding of a pair of elongated sheet member portions, each of said pair of elongated sheet member portions defining a second line of tearing weakness both ends of which are spaced from the edges of respective sheet member portions, whereby each second line may be individually torn open to define a retaining aperture for receiving a sample tube and the like.
Claim 6
Dependent Claim
54 words
The plastic container of claim 4 defining sealed, opposed ends, and including retention member means positioned at each end of the plastic container, said retention member means being integrally attached to said container and comprising open transverse channel means proportioned to receive a length of flexible tubing wound about the ends of said container.
Claim 7
Dependent Claim
44 words
The plastic container of claim 5 in which the retention member means at each end of said container each defines a plurality of open transverse channel means to permit the winding of multiple coils of said flexible tubing about the ends of said container.
Claim 8
Dependent Claim
30 words
The plastic container of claim 6 which carries a length of flexible tubing wound about the ends of said container and occupying the open transverse channel means of said container.
Claim 9
Dependent Claim
63 words
In a plastic container defining sealed, opposed ends, one of said ends carrying access port means, the improvement comprising: retention member means positioned at the edge of each end of said plastic container, said retention member means being integrally attached to said container and comprising open transverse grooves proportioned to receive a length of flexible tubing wound about the ends of said container.
Claim 10
Dependent Claim
63 words
In a plastic container defining sealed, opposed ends, one of said ends carrying access port means, the improvement comprising: retention member means positioned at the edge of each end of said plastic container, said retention member means being integrally attached to said container and comprising open transverse grooves proportioned to receive a length of flexible tubing wound about the ends of said container.
Claim 11
Dependent Claim
43 words
The plastic container of claim 8 in which the retention member means at each end of said container each defines a plurality of open transverse grooves to permit the winding of multiple coils of said flexible tubing about the ends of said container.
Claim 12
Dependent Claim
30 words
The plastic container of claim 9 which carries a length of flexible tubing wound about the ends of said container and occupying the open transverse channel means of said container.
Claim 13
Dependent Claim
14 words
The plastic containier of claim 8 which is blow molded from a tubular parison.
Claim 14
Dependent Claim

The plastic container of claim 11 which defines flexible, collapsible walls and defines access port means at one end thereof.
Claim 15
Dependent Claim
32 words
The plastic container of claim 12 in which said retention member means comprise an integral part of the container and are molded from said parison during the blow molding of said container.
Claim 16
Dependent Claim
50 words
The plastic container of claim 13 in which said retention member means at the opposed ends thereof are also positioned at opposed sides on said ends of the container whereby said flexible tubing may be wound about the container ends in diagonal relation to the longitudinal axis of said container.
