Abstract

A container for separately accommodating two materials and mixing the same, has a first and second wall bounding a wider and narrower chamber, a connecting sleeve having one portion which is sealingly fitted on the first wall and another portion extending in an opposite direction and having an outer thread, a discharge cap connected to the second wall and having an inner thread which meshes with the outer thread of the other portion of the connecting sleeve so that the discharge cap is movable relative to the connecting sleeve, and a separating member having a separating portion which disconnects the chambers from one another and a projecting portion which extends into the narrower chamber and is held by the second wall. The second wall has an outer projection engaging in an inner groove in the other portion of the connecting sleeve so as to retain the discharge cap on the other portion of the connecting sleeve during unscrewing of the former. The groove has a length which is substantially equal to the length of the projecting portion of the separating member.
