Abstract

The present invention relates to a double-walled vessel for storing a potable liquid, particularly a hot drink such as coffee, comprising an inner container ( 12 ) that encloses a cavity ( 34 ) for receiving the liquid and that forms at least one support surface ( 46 ), and an outer container ( 14 ) which comprises at least two shells ( 16, 18 ) that are detachably interconnectable, wherein the outer container ( 14 ) at least partially encloses the inner container ( 12 ) when in the connected state, and is supported against the support surface ( 46 ) when in the connected state.

First claim

The invention claimed is:

1. A double-walled vessel for storing a potable liquid, particularly a hot drink such as coffee, the double-walled vessel comprising:
an inner container ( 12 ) that encloses a cavity ( 34 ) for receiving the liquid and that forms at least one support surface ( 46 ), and
an outer container ( 14 ) which comprises at least two shells ( 16 , 18 ) that are detachably interconnectable, wherein the outer container ( 14 ) at least partially encloses the inner container ( 12 ) when in a connected state and is supported against the at least one support surface ( 46 ) when in the connected state,
wherein the outer container ( 14 ) has a fixing device ( 20 ) for fixing the at least two shells ( 16 , 18 ) in the connected state and the fixing device ( 20 ) has a latching connection ( 22 ) for detachable connection of the at least two shells ( 16 , 18 ).

2. The double-walled vessel according to claim 1 , wherein the inner container ( 12 ) defines a longitudinal axis (L) and the support surface ( 46 ) is formed by a section ( 43 ) of the inner container ( 12 ) inclined relative to the longitudinal axis (L).

3. The double-walled vessel according to claim 2 , wherein the inner container ( 12 ) has an opening ( 36 ) for filling the liquid into the cavity ( 34 ) and for pouring the liquid out of the cavity ( 34 ), wherein, starting from the opening ( 36 ) and with respect to the longitudinal axis (L), the inner container ( 12 ) has an expanding section ( 42 ) on which the support surface ( 46 ) is arranged.

4. The double-walled vessel according to claim 3 , wherein the expanding section ( 42 ) is part of a convexly curved section ( 41 ) of the inner container ( 12 ) or transitions into the convexly curved section ( 41 ).

5. The double-walled vessel according to claim 3 , wherein, starting from the opening ( 36 ) and with respect to the longitudinal axis (L), the inner container ( 12 ) has a tapering section ( 38 ) that connects to the expanding section ( 42 ).

6. The double-walled vessel according to claim 1 , wherein the inner container ( 12 ) forms at least one contact surface ( 48 ) that contacts the outer container ( 14 ) in the connected state.

7. The double-walled vessel according to claim 1 , wherein the outer container ( 14 ) has a first seal ( 52 ) with which the outer container ( 14 ) is supported on the support surface ( 46 ).

8. The double-walled vessel according to claim 1 , wherein the outer container ( 14 ) encloses the inner container ( 12 ) in the connected state so that an intermediate space ( 50 ) is formed between the inner container ( 12 ) and the outer container ( 14 ).

9. The double-walled vessel according to claim 8 , wherein a first seal ( 52 ) seals the intermediate space ( 50 ).

10. The double-walled vessel according to claim 1 , wherein the outer container ( 14 ) has a second seal ( 54 ) that seals the at least two shells ( 16 , 18 ) in the connected state.

11. The double-walled vessel according to claim 1 , wherein the inner container ( 12 ) is made from glass and the outer container ( 14 ) is made from plastic.

12. A double-walled vessel for storing a potable liquid, particularly a hot drink such as coffee, the double-walled vessel comprising:
an inner container ( 12 ) that encloses a cavity ( 34 ) for receiving the liquid and that forms at least one support surface ( 46 ), and
an outer container ( 14 ) which comprises at least two shells ( 16 , 18 ) that are detachably interconnectable, wherein the outer container ( 14 ) at least partially encloses the inner container ( 12 ) when in a connected state and is supported against the at least one support surface ( 46 ) when in the connected state,
wherein the outer container ( 14 ) has a fixing device ( 20 ) for fixing the at least two shells ( 16 , 18 ) in the connected state and the fixing device ( 20 ) comprises an elastic band ( 32 ) that can be connected to the at least two shells ( 16 , 18 ).
