ABSTRACT:
This invention relates to an operationally reliable two-compartment container designed to prevent unintended use before application. The invention comprises a one-piece container having two compartments assembled one upon another, which are interlinked by a transfer opening into which a stopper is mounted to keep the contents of the two compartments separate during storage. The stopper is linked by supporting devices to the lower end of a pouring spout which seals the upper part of the container with a covering cap. The pouring spout is connected as a one-piece unit to an elastic membrane, which is turned inside of the container when closed, and outside when the container is opened, by which the pouring spout extends with an encompassing sealing cap into the collar region of the upper part of the compartment, is linked by a screw thread. The sealing cap is fitted with a safeguard against rotation at its junction point to the upper compartment to prevent premature removal of the covering cap, prior to admixture of the contents of the two compartments. The sealing cap includes a serration on the inside of the rim encompassing the covering cap under the sealing cap, and at least one corresponding cross-bar at the covering cap.
