1. A container for accommodating two materials separately from one another and mixing the same, comprisinga 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extending into said narrower chamber and being held by said second wall of the latter so that, when said second wall is withdrawn from said projecting portion of said separating member by unscrewing said discharge cap, said separating member is loosened and said chambers communicate with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.
