Abstract: A child-resistant closure for liquid medicaments consisting of two parts, a dosage cup and a bottle adapter. Dosage cup is configured to have cap lugs which reversibly engage helical locking lugs. In thread-on bottle adapter embodiments, helical locking lugs are located on the bottle adapter. In press-in bottle adapter embodiments, helical locking lugs are located on the neck finish of the bottle. A downward force is required to close the system, said force deforming a flexible shoulder, which in turn, creates an upwardly biasing force acting on the dosage cup to lock it in place in a child-resistant manner.

Abstract: A passive valve closure for liquid medicaments, configured to permit irreversible attachment to a pre-existing bottle and reversible engagement with a dosage cup bearing lugs such that when the dosage cup engages skirt lugs on the closure, a child-resistant closure is effected.

Abstract: A system for producing blow molded articles. The system includes an injector nozzle mounted to a parison cavity block having a parison cavity such that the injector nozzle injects molten plastic into the parison cavity to form a parison. The injector nozzle is mounted to the parison block by means of two seats, a distal seat where the distal end of the injector nozzle is seated within an opening in the parison cavity block and a proximal seat, a linear distance inwardly from the distal seat, where a circular flange on the injector nozzle is seated within an annular shelf formed in the parison block. The two spaced apart seats ensure an accurate alignment between the centerline of the injector nozzle and the parison cavity. As a further feature, there is a system to heat the nozzle tip to reduce the temperature differential between the nozzle and the parison cavity.

Abstract: An improved child-resistant closure for dispensers of liquid medicaments, the closure being of a two-part construction. The closure has an outer cap with a quantity of shoulder lugs and skirt lugs and an inner cap with a quantity of shoulder lugs and flexible beams. The closure has equal quantities of shoulder lugs on the inner and outer caps, equal quantities of skirt lugs and flexible beams, flexible beams having an arcuate underside, shoulder lugs having a depth to prevent hyper-flexion of the flexible beams, and an ideal overlap when the faces of the shoulder lugs are aligned. Additionally, provided are methods for attaching and removing the cap from a pre-existing bottle.

Abstract: A dispenser assembly for liquid products is disclosed. Such an assembly may include an elongated barrel, and an elongated plunger having a flexible sealing lip disposed at an end thereof. The sealing lip may have an outer diameter in a relaxed state that is greater than an internal cross-sectional diameter of the barrel. When the plunger and barrel are actuated axially relative to one another, the sealing lip flexes inwardly and provides the sole contact between the plunger and the barrel.

Abstract: An adapter to be pressed into the neck of a bottle to receive a syringe for accessing the bottle contents by a syringe. The adapter has a distal end that extends into the bottle and a normally closed valve located at that distal end to prevent the contents from leaking out of the bottle if the bottle is inverted. An upper flange of the adapter seats against the top of the bottle and is recessed into the top of the bottle to prevent easy access to pry the adapter out of the bottle. A cap is also disclosed that is adapted to be pressed into the neck of a bottle. The cap has an upper lid that is hinged to a lower body to allow the upper hinge to move between a closed position sealing the bottle and an open position where the bottle is accessible by a syringe.

Abstract: A dispenser assembly for liquid products is disclosed. Such a dispenser assembly may include an elongated barrel, and an elongated plunger positioned therein with the elongated plunger having a flexible sealing lip disposed at an end thereof. The sealing lip may have a beaded portion providing for easier movement of the plunger within the barrel while creating an effective seal between the plunger and the barrel. In an embodiment, the cross-section of the beaded portion is oval and the thickness of the flexible sealing lip tapers inwardly towards it distal end. The flexible sealing lip may be curved in the shape of an arc of a circle.

Abstract: A dispenser assembly for liquid products comprising an elongated, generally cylindrical barrel of a predetermined internal cross-sectional diameter having a discharge opening at one end and open at its opposite end, an elongated, generally cylindrical hollow plunger having an outer diameter less than the barrel internal diameter and a circumferentially extending axially directed sealing lip adjacent the tip portion having an outer diameter greater than the internal diameter of the barrel in the relaxed state to thereby flex the lip inwardly against its bias and providing the sole sliding contact between the plunger and barrel when the plunger and barrel are actuated axially relative to one another.

Abstract: Apparatus for molding plastic caps having inclined tabs integral with the lower edge of the cap skirt and radially inwardly extending ribs integral with the inner surface of the cap skirt. The tabs and ribs are formed by a plurality of blades having recesses on the ends thereof corresponding to the configurations of the tabs and ribs. The blades are mounted on a core and extend into a female mold having a cup-shaped cavity. A linear drive member is mounted on a fixed plate assembly and connected to a ratchet sleeve rotatably mounted on a movable plate assembly. The end of the ratchet sleeve is provided with circumferentially spaced teeth engaging the lower peripheral edge of the cap skirt. Movement of the movable plate assembly relative to the fixed plate assembly causes the ratchet sleeve to rotate to move the molded tabs and ribs away from the recesses of the blades so that the finished cap can be stripped from the apparatus.
