Abstract
Abstract A can crimping and folding device is shown which has a base plate having a crimping area and a folding area. The areas are adapted to sequentially receive a can, the length of which is transversely aligned with the longitudinal axis of the base plate. A pivotable handle is attached at one end of the base plate and rotates toward and away from the base plate. The handle has a two-position can crimping portion adapted to meet the base crimping area and a can folding portion adapted to meet the base folding area. The can folding portion of the handle has double concave depressions therein to increase the mechanical advantage of the device.

Claim 1
Independent Claim
103 words
A can crimping and folding device, comprising: a base plate having a crimping area and a folding area, said areas being adapted to sequentially receive a can, the length of which is transversely aligned with the longitudinal axis of said base plate; a pivotable handle attached at one end of said base plate for rotation toward and away from said base plate, said handle having an elongated, two-position, can crimping portion adapted to meet said base crimping area and a can folding portion adapted to meet said base folding area; and said can folding portion of said handle having double concave depressions therein.
Claim 2
Dependent Claim
103 words
A can crimping and folding device, comprising: a base plate having a crimping area and a folding area, said areas being adapted to sequentially receive a can, the length of which is transversely aligned with the longitudinal axis of said base plate; a pivotable handle attached at one end of said base plate for rotation toward and away from said base plate, said handle having an elongated, two-position, can crimping portion adapted to meet said base crimping area and a can folding portion adapted to meet said base folding area; and said can folding portion of said handle having double concave depressions therein.
Claim 3
Dependent Claim
142 words
A can crimping and folding device, comprising: a base plate having a crimping area and a folding area, said areas being adapted to sequentially receive a can, the length of which is transversely aligned with the longitudinal axis of said base plate; a pivotable handle attached at one end of said base plate for rotation toward and away from said base plate, said handle having an elongated, two-position, can crimping portion adapted to meet said base crimping area and a can folding portion adapted to meet said base folding area, said can folding portion of said handle having double concave depressions therein; puncture means on said base folding area for puncturing each end of a can being folded; and retaining means between said base folding area and said base crimping area for locating and retaining a can on said base folding area.
Claim 4
Dependent Claim
142 words
A can crimping and folding device, comprising: a base plate having a crimping area and a folding area, said areas being adapted to sequentially receive a can, the length of which is transversely aligned with the longitudinal axis of said base plate; a pivotable handle attached at one end of said base plate for rotation toward and away from said base plate, said handle having an elongated, two-position, can crimping portion adapted to meet said base crimping area and a can folding portion adapted to meet said base folding area, said can folding portion of said handle having double concave depressions therein; puncture means on said base folding area for puncturing each end of a can being folded; and retaining means between said base folding area and said base crimping area for locating and retaining a can on said base folding area.
Claim 5
Dependent Claim
42 words
The can crimping and folding device of claim 2, wherein said puncture means is at least two spikes, one of which is located beneath each of said concave depressions in said can folding portion when said portion meets said can folding area.
Claim 6
Dependent Claim
27 words
