Abstract
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.
Claims12
A mixing and drinking beaker for mixing a first substance with a second substance comprising:
- a stiff vessel in which the first substance is located and having a longitudinal axis and a longitudinal opening at an upper end surrounded by an outer flange;
- a cover for said vessel which closes said opening, said cover including an outer cover member and an inner cover member between which a chamber is formed in which the second substance is located,
- said outer cover member being formed of a material which is softer and more elastic than that of said vessel and including an inner seat and a first sealing wall which elastically and sealing engages said outer flange of said vessel in an inward radial direction;
- said inner cover member being formed of a material which is softer and more elastic than that of said vessel and including a second sealing wall which sealingly and radially engages said seat of said outer cover member in an outward radial direction so that said chamber is sealed from said vessel,
- a releasing means for releasing said second sealing wall from said seat when said outer cover member is depressed in an axial direction so that said inner cover member is displaced downwards into said vessel and said chamber is open to said vessel for mixing of the first and second substances by shaking of said vessel and cover;
- and
- a band means which is positioned about said outer flange and said first sealing wall for exerting an inwardly directed radial tension force to increase the sealing engagement of said first sealing wall to said outer flange and the sealing engagement of the second sealing wall to said seat.
