ABSTRACT:
A pair of male and female mold parts in association with a closure for forming orifices during the thermal formation of a structure. The combination includes: a pair of mold members having a first mold member and a second mold member; at least one male key member carried by the first mold member having on at least one side thereof a planar face terminating in either a cutting edge or a bevelled face; at least one female key member carried by the second mold member having a pair of spaced planar faces each terminating in either a cutting edge or a bevelled face; wherein at least one of the key members is free to move independently of its mold member, the key members being dimensioned, constructed and registered so that a cutting edge of one key member will be opposite to a bevelled face of the other key member so that, on closure of the mold members with a softened sheet of plastic therebetween, the cutting edge of one key member will contact the sheet, ride off the bevelled face, the planar faces will come into alignment and, with a sliding relationship between the planar faces, the male key will cooperate with the female key to form the orifice.
