PCT No. PCT/EP92/01181 Sec. 371 Date Dec. 9, 1993 Sec. 102(e) Date Dec. 9, 1993 PCT Filed May 25, 1992 PCT Pub. No. WO92/22237 PCT Pub. Date Dec. 23, 1992.A mixing and drinking beaker with an adhesive, closing and sealing system between the cover and the beaker and with a chamber in the cover consisting of an outer cover and an inner cover therein after the adhesive and sealing system. The inner cover can be released from its seat without releasing the joint between the cover and the beaker without the need for any additional mechanism simply by the yielding of the sealing seat of the material surrounding the inner cover by pressure from outside axially to the outer cover on the handle and/or the surrounding area of the outer cover. In addition, the adhesive bond between the cover and the beaker can be changed to a positive bond by a shrink strip.
