A tamper-indicating closure for a container includes a cap with removable panels of a top wall of the cap. Each removable panel is connected to a tab on the inside of the cap. The top wall includes inner and outer cams on an inside surface and the tabs underlie the cams. A liner disc is applied inside the cap for sealing against the container. A plurality of spaced-apart ratchet teeth are arranged in one or two circular patterns on the liner disc and sized and located such that the circular pattern of teeth meshes with the two cams. The tabs have a toothed transverse cross-section which allow the tabs to ride over the ratchet teeth in a screwing-on direction to the cap, but the tabs are engaged by the ratchet teeth in a screwing-off direction of rotation of the cap. Since the liner disc and ratchet teeth are stationary with respect to the container, unscrewing of the cap causes the ratchet teeth to separate the panels from the moving cap.

Tamper-indicating closure

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.
