Child-resistant closure

Dispensing closure

Closure

There are various ways to latch a closure onto a container. It has been found that for blowmolded containers that the support flange for the bottle preform can later be used as a part of the latch mechanism to secure a closure onto the container. Preforms have a support flange by which the preform is handled prior to being placed into the mold and in the mold. Prior to being placed in the mold, the preform is heated to about 85&deg; C. to about 200&deg; C. During this time and in the mold, it will be supported by the support flange. This support flange is used after the container is blown and filled as one part of the latching mechanism of the closure. The closure will have a portion that is an interference fit with the support flange of the bottle to thereby secure the closure to the bottle.

Bottle with closure holding structure

A closure for a container having a dispensing nozzle include a central aperture to receive the nozzle. In one embodiment, the nozzle extends through the aperture and projects upwardly from the base cap. The base cap further includes a top wall inclined with respect to the central axis of the base cap to assist in dispensing of the contents of the container. A cap lid is hinged to the base cap by a snap hinge assembly.
