Abstract (en)
A pair of safety closure and container assemblies each including a container (210), cap (216) and combined spring and sealing member. A retention rib is formed on the inner surface of the skirt of the caps. A plurality of retention nibs (224) are formed on the inner surface of the skirt of the other cap (216). Spring and sealing members (225) each have a radially projecting flange (236) that engages the retention rib and the retention nibs (224) to prevent separation of the spring and sealing members (225) from the caps (216). Cap and container locking elements are formed respectively on the inner surfaces of the skirts (220) of the caps (216) and the outer surfaces of the mouths (212) of the containers (210). The cap and container locking elements are engageable with and disengageable from each other by combined axial and rotary motion of the caps (216) relative to the containers (210). The spring and sealing members (225) bias the cap and container locking elements toward locked engagement with each other when the caps (216) are applied to the containers (210). The cap and container locking elements are formed such that the sealing portions (234, 236) of the spring and sealing members are forced into the mouths (212) of the containers (210) into sealing engagement therewith as the caps (216) are rotated relative to the containers (210) so that the operator does not have to apply direct axial force to the caps (216) in order to seal the containers (210).
