Abstract
Abstract A device is disclosed for individually flattening cylindrical containers, such as metal cans. A base is provided for supporting a can in a crushing position in which the can is disposed on its side on the base. A lever mechanism is pivotally attached to the base and is swingable upwardly therefrom to a raised position to permit a can to be positioned on its side on the base and downwardly toward the base for crushing the positioned can. The lever mechanism is jointed and includes a can engaging edge projecting from the joint whereby the edge is pivotable both about the pivot axis of the lever mechanism on the base and about the joint to effect crushing of one side of the can at one end thereof with the one end flattened over the crushed side. The partially flattened can then is turned over for similarly flattening the other side and other end thereof until the can is completely crushed into a flattened condition.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
153 words
A device for individually flattening cylindrical cans, comprising: a base for supporting a can in a crushing position in which the can is disposed on its side on said base; and lever means pivotally attached to said base, said lever means being swingable upwardly from said base to a raised position to permit a can to be positioned on its side on said base and downwardly toward said base for crushing the positioned can, said lever means being jointed and including a can engaging edge projecting from the joint whereby the edge is pivotable both about the pivot axis of said lever means on the base and about said joint to effect crushing of one side of the can at a crease adjacent one end thereof with said one end flattened over said one side, the partially flattened can then being turned over for similarly flattening the other side and other end thereof.
Claim 2
Independent Claim
153 words
A device for individually flattening cylindrical cans, comprising: a base for supporting a can in a crushing position in which the can is disposed on its side on said base; and lever means pivotally attached to said base, said lever means being swingable upwardly from said base to a raised position to permit a can to be positioned on its side on said base and downwardly toward said base for crushing the positioned can, said lever means being jointed and including a can engaging edge projecting from the joint whereby the edge is pivotable both about the pivot axis of said lever means on the base and about said joint to effect crushing of one side of the can at a crease adjacent one end thereof with said one end flattened over said one side, the partially flattened can then being turned over for similarly flattening the other side and other end thereof.
Claim 3
Dependent Claim
15 words
The device of claim 1 wherein said base has a substantially flat can supporting surface.
Claim 4
Dependent Claim
40 words
The device of claim 2 wherein the pivot axis of said lever means on the base, the pivot axis of said joint, and said can engaging edge all extend generally parallel to said flat can supporting surface of said base.
Claim 5
Dependent Claim
24 words
The device of claim 1 wherein said base includes means for engaging and positioning a can during said flattening thereof by said lever means.
Claim 6
Dependent Claim
22 words
The device of claim 4 wherein said engaging and positioning means comprises abutment means for engaging said one end of the can.
Claim 7
Dependent Claim
19 words
The device of claim 5 wherein said abutment means is disposed adjacent the pivot axis of said lever means.
Claim 8
Dependent Claim
19 words
The device of claim 1 wherein said can engaging edge is rounded for crushing a can without cutting thereinto.
Claim 9
Dependent Claim
81 words
The device of claim 1 wherein said lever means comprises a first portion pivotally attached at one end thereof to said base and a second portion pivotally attached to the opposite end of said first portion, the pivot point of said second portion being disposed intermediate the ends thereof whereby said can engaging edge is formed by a projecting end of said second portion, and the opposite end of said second portion provides means for manual manipulation of said lever means.
Claim 10
Dependent Claim
65 words
The device of claim 8 wherein said first portion of said lever means comprises a pair of side arms joined by a generally flat upper plate which is spaced from the pivot axis between said first and second portions a distance sufficient to capture said one end of the can between said flat upper plate and said can engaging edge during flattening of the can.
Claim 11
Dependent Claim
15 words
The device of claim 8 wherein said base has a substantially flat can supporting surface.
Claim 12
Dependent Claim
40 words
The device of claim 10 wherein the pivot axis of said lever means on the base, the pivot axis of said joint, and said can engaging edge all extend generally parallel to said flat can supporting surface of said base.
Claim 13
Dependent Claim
27 words
The device of claim 8 wherein said base includes abutment means adjacent the pivot axis of said lever means for engaging said one end of the can.
Claim 14
Independent Claim
235 words
A device for individually flattening cylindrical cans, comprising: a base having a generally flat wall for supporting a can in a crushing position in which the can is disposed on its side on said flat wall; and lever means pivotally attached to said base and swingable upwardly therefrom to a raised position to permit a can to be positioned on its side on said flat wall of said base and downwardly toward said flat wall for crushing the positioned can, said lever means being jointed and including a first portion pivotally attached at one end thereof to said base and a second portion pivotally attached to the opposite end of said first portion, the pivot point of said second portion being disposed intermediate the ends thereof to define a can engaging edge formed by a projecting end of said second portion and the opposite end of said second portion provides means for manual manipulation of said lever means, whereby said can engaging edge is pivotable both about the pivot axis of said lever means on said base and about the pivot axis between said first and second portions of said lever means to effect crushing of one side of the can at a crease adjacent one end thereof with said one end flattened over said one side, the partially flattened can then being turned over for similarly flattening the other side and other end thereof.
Claim 15
Independent Claim
