Abstract: A male and female mold parts combination for forming a latch opening in a container molded from a softened sheet of plastic having a female mold key member arranged on the female mold part; a male mold key member arranged on the male mold part; a cutting edge adjacent to a planar face of one key and a vertical surface having a bevelled edge surface on the other key. The keys being normally registered so that on closure of the mold parts, initial contact will involve the cutting edge, the bevelled edge surface and the plastic therebetween. One of the keys is fixed in one of the mold parts and the other of the keys being located in the other of the mold parts and free to move independently of its mold part so that on closure of the mold parts the cutting edge will ride off the bevelled edge surface and slide across the vertical surface piercing and enlarging a latch opening in the plastic.

Abstract: A dough delivery or divider assembly having a plurality of ports integrally formed in a cylindrical dispensing structure and incorporating an external pressurizing structure wherein a negative pressure or vacuum is applied to the interior of each of the ports from an exterior location relative to the cylindrical surface in which the ports are formed. The vacuum is maintained within the ports until they are exposed to the supply dough within a supply hopper wherein the negative pressure aids forcing of the dough into the ports for transportation to a delivery site at which location the dough portions are removed from the ports.
