Abstract
Abstract A base providing a platform on which a container to be crushed rests in a fixed position and a spring-supported lever pivotally connected at one end of said base. Force applied to the free end of the lever to overcome the support provided by the spring moves the lever into parallel alignment adjacent the top of said base thereby flattening the container.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
In a device for crushing containers, a base member, a lever pivotally attached to said base member, a pressure plate attached to said lever, variable container positioning means on said base member to secure the container against motion away from the point of pivotal connection of said lever on said base member and against motion laterally of said base member, said variable container positioning means comprising the combination of a depression in the upper surface of said base member extending longitudinally of said member and with a multiplicity of holes projecting through said member, and a pin designed to be selectively inserted into such holes, and a cutter connected to said lever extending below said lever and aligned with said positioning means so that said pressure plate is supported by said base when said lever is fully lowered.
Claim 2
Dependent Claim
138 words
In a device for crushing containers, a base member, a lever pivotally attached to said base member, a pressure plate attached to said lever, variable container positioning means on said base member to secure the container against motion away from the point of pivotal connection of said lever on said base member and against motion laterally of said base member, said variable container positioning means comprising the combination of a depression in the upper surface of said base member extending longitudinally of said member and with a multiplicity of holes projecting through said member, and a pin designed to be selectively inserted into such holes, and a cutter connected to said lever extending below said lever and aligned with said positioning means so that said pressure plate is supported by said base when said lever is fully lowered.
Claim 3
Dependent Claim
27 words
In a device for crushing containers as described in claim 1 in which said cutter is in longitudinal alignment with and designed to fit within said depression.
Claim 4
Dependent Claim
50 words
In a device for crushing containers as described in claim 2 in which said cutter when within said depression terminates prior to the hole nearest the point of pivotal connection of said lever on said base member so as not to contact said pin when in inserted in said hole.
Claim 5
Dependent Claim
27 words
In a device for crushing containers as described in claim 1 in which said pin, when in any of said holes, cannot be contacted by said edge.
