A compression molding apparatus includes a female mold half which receives a charge of molten plastic and a cooperating male plunger which compression molds the molten plastic into an article within the female mold half. A slide mold part is located between the male plunger and the female mold half. The slide mold part includes left and right slide mold halves which when brought into juxtaposition, define a central mold space. The left and right mold halves are slidable toward and away from each other, to form the central mold space and to open the central mold space respectively. The male portion is reciprocated downwardly to undertake the compression molding, and a cam mechanism is activated by the reciprocation to close the slide mold part during compression molding. The return stroke opens the slide mold part to allow removal of the molded article without stripping or unscrewing the molded article from the slide mold part. In an exemplary embodiment, a bottle-like container is formed by compression molding which includes a neck having an external thread. The external thread is formed in the central mold space of the slide mold part. The cam mechanism is arranged to open the slide mold part to release the threaded neck of the container for removal from the mold apparatus.

A closure includes a promotion piece holding container within a cap to be installed onto a container such as a bottle. The promotion piece receiving container includes a top flange captured by a lip of a seal installed within the cap. The promotion piece receiving container includes a frangible band extending circumferentially around a substantial circumference of the container. The container can include a bottom flange arranged for convenience gripping and removing of the container from the cap, and a pull tab attached to the frangible band to assist in removing the frangible band to open the container for removal of the promotion piece.

Easy-open promotion compartment

A promotional closure includes a sealed promotion-receiving member in the form of a compartment positioned generally within an outer closure cap, for disposition within an associated container. The sealed configuration of the promotion compartment desirably acts to isolate the promotional element therein from the contents of the container. Use on a container having carbonated contents is particularly facilitated by an arrangement by which a plastic film cover member which seals the compartment is sealed to an annular flange of the compartment to permit predetermined delamination and release of gas pressure from within the interior of the compartment.

Closure having self-venting, sealed promotion compartment

A removable inner compartment promotional closure includes a plastic closure cap having a circular top wall portion and a depending annular skirt portion depending from the top wall portion. A circular, resilient liner is positioned in the cap, and has a retaining element extending therefrom. A removable compartment member is positioned in the closure cap in engagement with the retaining element. The compartment defines an interior compartment adapted to receive promotional indicia, such as a promotional game piece, therein. The compartment is adapted to release from the cap after the cap is removed from the container. A sealed cover element may be positioned to extend over and close the compartment member, to isolate the compartment from the contents of the container. The promotional closure is used in conjunction with a simulated promotional closure, which configured to be is indistinguishable from the promotional closure cap. A promotional gaming system includes a plurality of the simulated promotion containing closures and the promotional closures provided on respective containers. Purchasers of the soft drink with the promotional closure will be instantly rewarded upon opening the container and compartment by receiving the promotional piece, 'on-the-spot.' Purchasers of the soft drink with the simulated promotional closure may be consoled by indicia, such as 'please try again' appearing in the simulated promotional closure.

Removable inner promotional compartment closure and promotional gaming

A promotional closure for use with an associated container includes a plastic closure cap having an inwardly recessed, circular top wall portion defining a compartment and a depending annular skirt portion depending from the top wall portion. A circumferential lip formed in the closure cap generally at about a periphery of the compartment, defines a circumferential channel-like recess adjacent to the compartment. The closure further includes a removable, circular cover member adapted to cover the compartment by insertion into the circumferential recess. The cover has a pair of circumferentially opposed tab-like, releasable engaging members which are adapted to be received in the circumferential recess to retain the cover in place in the cap over the compartment. The engaging members are further adapted to release from the recess for removal of the cover member from the top wall portion when pressure is applied to the cap on the skirt portion adjacent to where the engaging members are positioned in the recess to thereby permit access to the compartment. Alternately, the cover includes a depending skirtlike seal support member which exerts an outward force on the top wall portion to urge the top wall portion into sealing engagement with an inside surface at the mouth of the container.
