Abstract: A closure cap for use in combination with a container outlet is configured with a child-resistant feature involving a pair of abutment projections formed as part of the container outlet and a pair of abutment ribs formed as part of the closure cap. The container outlet is externally threaded and includes a dispensing opening. The container outlet also includes an annular skirt which provides a support surface for the pair of abutment projections. The closure cap is internally threaded and the pair of spaced-apart abutment ribs are designed to ride over each abutment projection during the threaded advance of the closure cap onto the container outlet. During retrograde rotation of the closure cap from the container outlet, the abutment ribs are designed to abut up against the abutment projections. The abutment ribs are manually movable in a radially inward direction for taking each abutment rib out of abutting engagement with a corresponding abutment projection.

Abstract: A child-resistant closure that includes a base wall, a peripheral outer wall extending from the base wall, and an inner wall spaced radially inwardly from the outer wall and having an internal thread for securement to a container finish. The outer wall of the closure has diametrically opposed circumferential gaps, and the inner wall extends axially in radial alignment with the gaps in the outer wall for circumferential abutment with lugs on a shoulder of the container. The inner wall is flexible inwardly for clearing the container lugs and permitting removal of the closure from the container finish. The outer wall thus protects the force application area of the inner wall by reason of the fact that such force application area is recessed inwardly with respect to the circumference of the outer wall. The closure resists application of planer force to the removal area of the inner wall, such as by a child biting the closure.

Abstract: The present invention is directed towards a closure and container combination wherein the container has a collapsible neck finish.

The closure for the combination has a retaining bead formed just below the top wall, the area in between receiving the spring bead of the container. The container and closure combination have interlocking structures comprised of locking lug and stop member on the container neck forming a recess therebetween which receives a locking tab on the lower periphery of the side wall of the closure. The interlocking structure is so formed that when the locking tab is located between the locking lug and stop member, the spring bead is firmly held in place below the top wall of the closure.

Abstract: A child resistant cap including relatively thin threads which, when the cap is in a relaxed condition, are spaced from the bottle neck, said spacing permitting the cap to be squeezed inward at points on opposite sides of the cap so that the cap responds to the squeezing by expanding outward at points ninety degrees from the squeezing points so that stops on the cap at the cap expanding location will miss the stops normally engaged when in a relaxed condition, thereby permitting the cap to be removed from the bottle. The cap may also include a guide ring in the cap interior to guide the cap over the bottle neck to help ensure that the cap is centered on the bottle opening. The cap may include pressure pads on the cap skirt outside near the cap bottom showing the user where to press and stiffening the portion of the cap where pressure is to be applied. And, the cap may include a tamper indicating ring which will separate from the cap the first time the cap is removed from the bottle.

The closure lower member has a pouring spout connected to the base member. The screw cap has a cap bottom and a cap side wall with an internal thread adapted to be screwed onto and unscrewed from the pouring spout which has an external thread. The cap side wall of the screw cap in a region of its free end face terminates in at least one latching lug, the latching lugs of the screw cap co-operating with latching projections of the closure lower member to form a latch connection. In a screwing on direction the closure lower member has a shallow rising flank which merges into a steep latching flank and also forms the latching connection with the latching lugs, the connection being reversible by displacement of the latching lugs in relation to the latching projections.

Abstract: The child resistant safety closure is one that uses a common single start thread on the neck of a container and on a closure. In conjunction with this single start thread there is a single mating projection on the neck and on the closure. These mating projections are in an interference fit until the closure is distorted so that the closure bows outwardly in the region of the projections whereby the projection on the neck and the projection on the closure can pass by one another. The distortion is enhanced by having the plastic of the closure in the area of the projection of a decreased thickness and the neck having flattened portions to provide for a easy distortion of the closure. By the use of a single start common thread and one projection the same closure can be used for containers requiring a safety closure and those not requiring a safety closure. The difference will solely be in the neck finish of the container or on the inner surface of the closure.
