Abstract: A dosing bottle is made by injection molding a synthetic resin preform with a threaded neck finish portion and a body portion. The neck finish has an internal collar adjacent said lower end thereof. The preform is removed from the injection mold and inserted into the mold of a blow molding machine. The mold has a cavity with a body portion conforming to the desired configuration and dimensions for the body of the bottle and a neck portion closely conforming to the configuration and dimensioning of the neck portion closely conforming to the configuration and dimensioning of the neck portion of the preform. The preform is heated and inserted into the blow mold cavity with the neck finish portion of the preform being sealed from the body portion of the cavity. Air is introduced into the body portion of the preform to blow the body portion of the preform into conformity with the body cavity while precluding any distortion of the collar and of the neck finish.

Abstract: A closure for a container with a threaded neck has a generally cylindrical body member and a disc pivotally mounted thereon. The body member has a peripheral wall with a lower, internally threaded skirt portion and a transversely extending wall intermediate the axial length of the body member above the skirt portion. The peripheral wall and transversely extending wall define a generally cylindrical cup portion above the transversely extending wall, and the transversely extending wall has a slot adjacent the inner periphery of the peripheral wall. The disc seats in the cup portion and is pivotally mounted on the peripheral wall of the body member about its periphery spaced above the transversely extending wall. The disc has a depending leg portion which extends through the slot in the transversely extending wall, and is pivotable about the points to move the leg portion downwardly and upwardly in the slot.
