ABSTRACT:
Disclosed herein is a cap having a lower cap coupled with an upper cap. The lower cap has an insertion part defining an adjunct receiving chamber formed therein. The upper cap has a security band removeably connected thereto by a connection member. Also an inner skirt extends downward from the upper cap and extends into the insertion part of the lower cap. A push bar extends downwards from the inner skirt further into the insertion part of the lower cap. The insertion part of the lower cap has a bottom opening, which is covered with a bottom cover joined along a bottom circumferential edge of the insertion part surrounding the bottom opening of the insertion part. The bottom circumferential edge of the insertion part is angled to have a downward slope with respect to a lateral direction. The push bar of the upper cap is positioned so that a lower end of the push bar is positioned at a lowest part of the insertion part. The push bar and bottom cover is formed so that a rotation of the upper cap in a predetermined direction will cause the push bar to cut the bottom cover to expose the bottom opening and discharge the adjunct therethrough, and further rotation will cause rotation of the lower cap and eventual detachment of the lower cap and upper cap from the container.
