Abstract: A child-resistant and senior-friendly package comprising one or more blister cards housed within a hollow molded plastic sleeve is provided. The sleeve is assembled from a pair of identical molded plastic body sections. Each body section has a latch and an unlocking tab and the blister card has a latch-catcher for cooperating with the latch to automatically lock the blister card in a storage position within the sleeve. The sleeve has a pair of opposite spaced-apart tabs in the side edges thereof that must be simultaneously pressed to unlatch the latches from the latch-catchers to permit the blister card to be slid from the storage position to a dispensing position. When pressed, the tabs flex the blister card off adjacent latches. An embodiment including a pair of separate blister cards is provided in which the blister cards are dispensed through opposite dispensing ends of the sleeve.

Abstract: A method and apparatus for blow molding articles with deeply recessed edges utilizing mold halves each of which consists of a center section and end sections that are relatively movable in a direction lengthwise of the mold to enable both lengthening and shortening of the mold. Rack and pinion assemblies are associated with the mold sections so that in response to movement of one end section toward or away from the center section, the other end section is similarly moved toward or away from the center section to thereby enable selective lengthwise lengthening or shortening of the mold halves. This enables the mold halves to be shortened after they are closed on a parison to thereby compress the shape of the parison within the mold to thereby move portions of the parison closer to the edges of the mold cavity. This facilitates a uniform distribution of plastic material along the surface of the mold cavity when the parison is blown into conformity with the mold cavity.
