Abstract
Abstract A device for compacting the containerizing compactible material such as leaves, grass and trash is provided. The device consists of a directing element having a front funnel section and a rear conduit, a rake and plunger element which is used to introduce material into the funnel section and force such material through the conduit; and a tubular netted bag having an open end mounted over the rear conduit. As material is pushed into the bag air is displaced ahead of and out the spaces in the netting material. The device can be assembled on legs to be used in an upright position and can be easily stored on a wall.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
A device for compacting and containing compactible material comprising: (a) a directing element having a front funnel which converges into a rear conduit; (b) a rake and plunger element having a handle and a rake member attached thereto for raking compactible material and plunging said material through said conduit; (c) a netted material for containing said compactible material having a closed end and having an open end bunched over said rear conduit; and (d) means for creating a resistance to compaction of said netted material on said conduit; whereby compactible material forced through said rear conduit is introduced into said netted material and said bunched netted material feeds out from said conduit in response to the compaction force of the rake and plunger element against said compactible material until a netted container of compactible material of desired length is obtained.
Claim 2
Independent Claim
140 words
A device for compacting and containing compactible material comprising: (a) a directing element having a front funnel which converges into a rear conduit; (b) a rake and plunger element having a handle and a rake member attached thereto for raking compactible material and plunging said material through said conduit; (c) a netted material for containing said compactible material having a closed end and having an open end bunched over said rear conduit; and (d) means for creating a resistance to compaction of said netted material on said conduit; whereby compactible material forced through said rear conduit is introduced into said netted material and said bunched netted material feeds out from said conduit in response to the compaction force of the rake and plunger element against said compactible material until a netted container of compactible material of desired length is obtained.
Claim 3
Dependent Claim
10 words
The device of claim 1 which further comprises a handle.
Claim 4
Dependent Claim
17 words
The device of claim 1 which further comprises means for anchoring said directing element to the ground.
Claim 5
Dependent Claim
15 words
The device of claim 1 wherein said compactible material is leaves, grass and mixtures thereof.
Claim 6
Independent Claim
171 words
A method for compacting and containing compactible material in a netted material comprising: (a) providing a directing element having a front funnel section which converges into a rear conduit, said rear conduit having bunched thereover the open end of a netted material having a closed end and means for creating a resistance to compaction of said netted material on said conduit; (b) gathering a quantity of compactible material with a rake and plunger element having a handle and rake member attached thereto; (c) introducing said compactible material into said funnel section with said rake and plunger element and plunging said leaves through said rear conduit into said netted material, said netted material feeding off said conduit in response to the compaction force of the rake and plunger element against said compactible material until a netted container of compactible material of desired length is obtained; (d) removing said netted material from said rear conduit; and (e) securing said open end of said netted material to form a closed container of netted material.
Claim 7
Independent Claim
171 words
A method for compacting and containing compactible material in a netted material comprising: (a) providing a directing element having a front funnel section which converges into a rear conduit, said rear conduit having bunched thereover the open end of a netted material having a closed end and means for creating a resistance to compaction of said netted material on said conduit; (b) gathering a quantity of compactible material with a rake and plunger element having a handle and rake member attached thereto; (c) introducing said compactible material into said funnel section with said rake and plunger element and plunging said leaves through said rear conduit into said netted material, said netted material feeding off said conduit in response to the compaction force of the rake and plunger element against said compactible material until a netted container of compactible material of desired length is obtained; (d) removing said netted material from said rear conduit; and (e) securing said open end of said netted material to form a closed container of netted material.
Claim 8
Dependent Claim
13 words
The method of claim 5 which further comprises repeating steps a to c.
Claim 9
Dependent Claim
13 words
The closed container of netted material produced by the process of claim 5.
Claim 10
Dependent Claim
13 words
The closed container of netted material produced by the process of claim 6.
