ABSTRACT:
A plastic molding apparatus for forming three-dimensional containers from a single sheet of plastic material and each comprising side-by-side generally dish-shaped members which are hinged together which dish-shaped members have different interior configurations with respect to one another. The apparatus comprises a pair of superimposed relatively movable male and female mold members. A pair of differently configurated side-by-side mold sets are carried by the mold members. A first plurality of different inserts having different projecting configurations are provided for said first mold set. A second plurality of different inserts are provided for the second set which have surface complementary to the first projecting inserts to establish a male-female mold relationship between the first and second plurality of inserts. Quick change means are provided for individually detachably securing the first and second inserts to the associated male and female mold members and thus enabling the molds to produce containers having variable predetermined physical characteristics. Means is provided on the mold members between the pairs of mold sets for producing a hinge between the dish-shaped members. Power means is provided for operating the mold members to produce the hingedly connected side-by-side dish-shaped members from the single sheet of material positioned therebetween.
