ABSTRACT:
A threaded tabbed cap for being threadably interfaced with a container, particularly a plastic beverage container, wherein the tabs admit unidirectional assistance to a user in the direction of unthreading. A top wall is integrally formed with annular sidewall. At the interior side of the annular sidewall, threads are provided which have a predetermined structure to threadably engage the threads adjacent the opening of a predetermined container. A pair of tabs are integral with the exterior side of the annular sidewall and are located at opposing sides thereof. The tabs are of an asymmetric shape so as to provide aid to unthreading it from the container but not offer aid to threading it onto the container. In this regard, each tab has a forward face projecting radially from the exterior side of the annular sidewall and a rearward face tangential with an interface of the annular sidewall. It is preferred for the forward face to be concavely shaped, and for the rearward face to be substantially straight between the interface thereof with the annular sidewall and the apex. In the preferred embodiment, the tabbed cap is composed of a plastic material, wherein the tabs generally extend from the top wall to the cap opening in longitudinal relation to the cap.
