Abstract
An apparatus for crushing containers includes a die defining an opening, a punch, and a system for displacing the die and punch relative to each other. The punch may be fixed and the die may be moved from a first position spaced apart from the punch such that a container to be crushed can be placed between the punch and die and a second position in which the punch extends into the die opening to define an annular gap between the punch and die opening. The arrangement is such that a container crushed between the die and punch as a result of displacement of the die to the second position is at least in part forced into and deformed within the annular gap.

An apparatus for crushing containers, comprising a die defining an opening, a punch, and means for displacing the die and punch relative to each other between a first relative position in which the die and punch are spaced apart such that the container to be crushed can be placed between them and a second relative position in which the punch extends into the die opening to define an annular gap between the punch and die opening, wherein a container crushed between the die and punch as a result of their displacement to the second relative position is at least in part forced into and deformed within the annular gap, and wherein the punch supports a retractable guide peg which may be inserted into a container to be crushed and which retracts as the die and punch move to the second relative position.
