Abstract
Abstract A continuous, relatively stiff ring capable of being coiled to form at least a pair of adjacent, generally circular loops of substantially the same size, about which the mouth of a flexible bag may be tucked as the loops are rolled over one another several times to, in turn, cause the bag mouth to be rolled a number of times about the loops and to be captured thereby, so that the loops hold open the bag mouth.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
81 words
Apparatus comprising: a flexible bag having a mouth portion; and an endless member defining a continuous ring coiled to form at least two adjacent and overlapping, generally circular loops adapted to receive said bag mouth, the bag mouth being wrappable about the loops when the loops are rolled about each other a number of times to releasably couple the bag mouth to the member, said member provided with sufficient rigidity so that said bag mouth is held in an open position.
Claim 2
Dependent Claim
81 words
Apparatus comprising: a flexible bag having a mouth portion; and an endless member defining a continuous ring coiled to form at least two adjacent and overlapping, generally circular loops adapted to receive said bag mouth, the bag mouth being wrappable about the loops when the loops are rolled about each other a number of times to releasably couple the bag mouth to the member, said member provided with sufficient rigidity so that said bag mouth is held in an open position.
Claim 3
Dependent Claim
10 words
The apparatus of claim 1, wherein the member is plastic.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1, wherein said member includes a generally smooth outer surface.
Claim 5
Dependent Claim
12 words
The apparatus of claim 3, wherein the member is annular in cross-section.
Claim 6
Dependent Claim
29 words
The apparatus of claim 1, wherein said member is initially elongated to present a pair of opposed ends, and including means coupled with the ends for joining the same.
Claim 7
Dependent Claim
11 words
The apparatus of claim 5, wherein the ends are releasably joined.
Claim 8
Dependent Claim
17 words
The apparatus of claim 5, wherein the member is composed of a number of releasably interconnected sections.
Claim 9
Dependent Claim
109 words
In combination: a flexible bag having a mouth portion defining an opening; an elongate member having a generally annular cross-section and opposed ends; and means coupled to at least one of the ends for releasably joining said ends to form a continuous ring capable of being coiled to form at least two adjacent, generally circular loops having the mouth portion inserted therethrough and wrapped thereabout by rolling the loops about each other a number of times to releasably capture said mouth portion to said loops, said member provided with sufficient rigidity to hold said opening in an open position when said mouth portion is releasably coupled to said member.
Claim 10
Dependent Claim
