Abstract
Abstract A device for holding a flexible, nonselfsupporting bag in an opened position for allowing the bag to be filled with leaves, grass or the like. The device includes a body member having a cavity therethrough substantially in the shape of a truncated right cone with the large end of the cone normally directed downward. The bag is inserted into the hollow body member and the mouth of the bag is attached to the top of the body member in an opened position. Once the bag is filled, the mouth of the bag is detached from the top of the body member and the body member is lifted over the bag. The sloping sides of the cavity in the body member makes the device easy to lift over the filled bag.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
156 words
A device for holding a flexible, nonselfsupporting bag in an opened position to allow said bag to be filled, said device comprising: a one-piece body member including a continuous side wall member and having a normally upwardly directed end and a normally downwardly directed end, said body member having a cavity extending completely therethrough from said normally upwardly directed end to said normally downwardly directed end for receiving said bag, said side wall having one or more apertures therethrough adjacent and conterminous with said normally downwardly directed end for allowing escapage of air from within said cavity when said bag is inserted into said cavity, said side wall being solid except for said one or more apertures, said cavity constantly increasing in cross-sectional area as it extends from said normally upwardly directed end to said normally downwardly directed end for allowing said device to be easily lifted over said bag after said bag has been filled.
Claim 2
Independent Claim
156 words
A device for holding a flexible, nonselfsupporting bag in an opened position to allow said bag to be filled, said device comprising: a one-piece body member including a continuous side wall member and having a normally upwardly directed end and a normally downwardly directed end, said body member having a cavity extending completely therethrough from said normally upwardly directed end to said normally downwardly directed end for receiving said bag, said side wall having one or more apertures therethrough adjacent and conterminous with said normally downwardly directed end for allowing escapage of air from within said cavity when said bag is inserted into said cavity, said side wall being solid except for said one or more apertures, said cavity constantly increasing in cross-sectional area as it extends from said normally upwardly directed end to said normally downwardly directed end for allowing said device to be easily lifted over said bag after said bag has been filled.
Claim 3
Dependent Claim
16 words
The device of claim 1 in which said body member includes a plurality of said apertures.
Claim 4
Dependent Claim
35 words
The device of claim 1 in which is included lock means for selectively holding said bag to said body member, said lock means being attached to said normally upwardly directed end of said body member.
Claim 5
Dependent Claim
32 words
The device of claim 3 in which said lock means includes a substantially downturned hook member fixedly attached to the outer edge of said normally upwardly directed end of said body member.
Claim 6
Dependent Claim
22 words
The device of claim 4 in which said hook member extends completely about said normally upwardly directed end of said body member.
Claim 7
Dependent Claim
19 words
The device of claim 1 in which said body member is in the shape of a hollow, truncated cone.
Claim 8
Dependent Claim
14 words
The device of claim 1 in which the walls of said cavity are smooth.
Claim 9
Dependent Claim
188 words
The combination with a flexible, nonselfsupporting garbage bag of a device for holding said bag in an opened position to allow said bag to be filled, said device comprising: (a) a hollow one-piece body member including a continuous side wall member and having a normally upwardly directed first end and a normally downwardly directed second end, said body means having a cavity extending completely therethrough, said bag being received in said cavity, said cavity having smooth walls and constantly increasing in cross-sectional area as it extends from said first end to said second end for allowing said device to be easily lifted over said bag after said bag has been filled, said side wall member having one or more apertures therethrough located adjacent and conterminous with said second end for allowing escapage of air from within said cavity when said bag is inserted into said cavity, said side wall being solid except for said one or more apertures; and (b) lock means holding said bag to said body member, said lock means including a substantially downturned hook member fixedly attached to said first end of said body member.
Claim 10
Dependent Claim
