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.

A container for accommodating two materials separately from one another and mixing the same, comprising a first wall bounding a wider chamber for accommodating one material; a second wall bounding a narrower chamber for accommodating another material; a connecting sleeve member having one portion which extends in a first direction and is sealingly fitted on said first wall bounding said wider chamber, and another portion which extends in a second direction opposite to said first direction and has an outer thread; a discharge cap fixedly connected with said second wall and having an inner thread which meshes with said outer thread of the other portion of said connecting sleeve member, said discharge cap being screwed on said other portion and movable relative to the latter; a separating member having a separating portion arranged to disconnect said chambers from one another, and a projecting portion extending into said narrower chamber and being held by said second wall of the latter so that, when said second wall is withdrawn from said projecting portion of said separating member by unscrewing said discharge cap, said separating member is loosened and said chambers communicate with one another, said projecting portion of said separating member having a predetermined length; and means for retaining said discharge cap on said other portion of said connecting sleeve member during unscrewing of the former, said retaining means including an outer projection which is formed on said second wall in the region adjacent to said wider chamber, and an inner annular groove which is formed in said other portion of said connecting sleeve member also in the region adjacent to said wider diameter and in which said outer projection of said second wall movably engages, said annular groove extending in a direction away from said wider chamber and having a length which is substantially equal to the length of said projecting portion of said separating member.
