Abstract
Abstract An apparatus for opening containers and removing the contents from the containers. A wheel is rotatably mounted to a stand having recesses formed on its outer extremity for receiving containers dispensed from a first chute positioned over the wheel. The wheel is rotatably driven forcing the ends of the container past a pair of stationary blades which remove the ends of the container. A wall mounted to the stand has an upper curved surface which projects into the wheel so as to crush the containers after the ends have been removed. A receptacle is positioned under the wheel to catch the contents of the containers as the containers are crushed. A wedge mounted to the stand projects into the wheel removing the crushed empty containers from the wheel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
An apparatus for opening containers comprising: a support means; a wheel rotatably mounted to said means and having first and second sides and a circumferential extremity with recesses formed thereon, said recesses sized to receive and carry containers each having a first and second end projecting outward of said wheel; and, a first knife mounted adjacent said wheel and fixed relative to said means for removing said first end as said wheel rotates and carries said containers past said knife, and further comprising: a firsT member connected to said means adjacent a portion of said circumferential extremity, said first member positioned to contact and secure said containers within said wheel; a second member connected to said means adjacent a portion of said circumferential extremity, said second member having an upper edge curved into said wheel; and, a second knife mounted adjacent said wheel and fixed relative to said means for removing said second end as said wheel rotates and carries said containers past said second knife.
Claim 2
Independent Claim
166 words
An apparatus for opening containers comprising: a support means; a wheel rotatably mounted to said means and having first and second sides and a circumferential extremity with recesses formed thereon, said recesses sized to receive and carry containers each having a first and second end projecting outward of said wheel; and, a first knife mounted adjacent said wheel and fixed relative to said means for removing said first end as said wheel rotates and carries said containers past said knife, and further comprising: a firsT member connected to said means adjacent a portion of said circumferential extremity, said first member positioned to contact and secure said containers within said wheel; a second member connected to said means adjacent a portion of said circumferential extremity, said second member having an upper edge curved into said wheel; and, a second knife mounted adjacent said wheel and fixed relative to said means for removing said second end as said wheel rotates and carries said containers past said second knife.
Claim 3
Dependent Claim
40 words
The apparatus of claim 1 wherein: said first and second knives have main bodies with sharp tips, cutting edges, and mutually facing parallel surfaces; and further comprising: a container removal wedge connected to said means and projecting into said wheel.
Claim 4
Dependent Claim
47 words
The apparatus of claim 2 wherein: said wheel has a pair of parallel side walls spaced apart and defining said circumferential extremity and recesses; said second member and said wedge project between said side walls; and, said containers are metal cans having capped and closed tubular bodies.
Claim 5
Dependent Claim
151 words
A container opening apparatus comprising: support means; a carrier mounted to said means and having first and second sides, said carrier having recesses adapted to carry containers each having opposite ends with the opposite ends projecting outwardly beyond said first and second sides; and, a pair of stationary blades mounted on said support means, each of said blades being positioned adjacent one of said sides, said blades each having a main body with a pointed tip and a sharp cutting edge; and second means for causing relative motion between said carrier and said blades, and further comprising: a container crusher mounted to said means and positioned equidistant between said first and second sides, said crusher having a curved edge extending from exteriorly of said carrier to interiorly of said carrier; and, a container remover mounted to said means and positioned between said first and second sides and extending into said carrier.
Claim 6
Dependent Claim
151 words
A container opening apparatus comprising: support means; a carrier mounted to said means and having first and second sides, said carrier having recesses adapted to carry containers each having opposite ends with the opposite ends projecting outwardly beyond said first and second sides; and, a pair of stationary blades mounted on said support means, each of said blades being positioned adjacent one of said sides, said blades each having a main body with a pointed tip and a sharp cutting edge; and second means for causing relative motion between said carrier and said blades, and further comprising: a container crusher mounted to said means and positioned equidistant between said first and second sides, said crusher having a curved edge extending from exteriorly of said carrier to interiorly of said carrier; and, a container remover mounted to said means and positioned between said first and second sides and extending into said carrier.
Claim 7
Dependent Claim
47 words
The apparatus of claim 4 and further comprising: a first chute mounted over said carrier dispensing said containers to said carrier; a receptacle mounted beneath said carrier receiving the contents of said container; and, a second chute mounted to said means receiving said containers from said remover.
Claim 8
Dependent Claim
62 words
The apparatus of claim 5 and further comprising: a pair of parallel mounting plates having said carrier rotatably mounted thereon and being positioned outwardly of said blades, and wherein: said carrier is a wheel having a rim with an axis of rotation and a pair of side walls removably mounted to said rim; and, said crusher extends progressively closer to said axis.
Claim 9
Dependent Claim
40 words
The apparatus of claim 5 wherein: said tip of each blade is positioned adjacent said rim so as to pierce said ends, said main body of each blade closes said container holding the contents therein after said ends are removed.
