Abstract
Abstract An insulating container (10) is used for storing and dispensing (hot) liquids, especially freshly brewed coffee beverages. Within this insulating container (10), there is arranged a bag-like inner container (11) made of a flexible material which is thus flatly collapsible. The liquid is filled into the inner container (11), so that the latter completely fills out the inner space of the insulating container (10). A tube piece (22) attached to the inner container (11) and is passed through a channel (24) in the insulating container lid (10) to the outside. A filler pipe (26) for filling the inner container (11) or alternatively a tap (28) for dispensing the beverage can be connected to the end of the tube piece (22) which is located on the outside.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
An apparatus for receiving and dispensing hot or cold liquid, comprising: a thermally insulating container having an interior and an open end; covering means for covering the open end of the insulating container; a flexible gas-tight inner container positioned within the interior of the thermally insulating container for receiving the liquid and for being collapsed into a flat state as liquid is dispensed from the inner container; a connecting piece mounted on the inner container and a tube connected to the connecting piece for dispensing liquids from the inner container, said covering means being oriented downwardly during dispensing of the liquid from the inner container; a channel formed in the covering means and extending between the interior of the insulating container and the exterior of the insulating container, said tube being removably positioned in and extending through said channel; said insulating container being removably positioned within the interior of the insulating container; and an air pipe extending through the covering means from the interior of the insulating container to the exterior of the insulating container for venting the interior of the insulating container.
Claim 2
Independent Claim
183 words
An apparatus for receiving and dispensing hot or cold liquid, comprising: a thermally insulating container having an interior and an open end; covering means for covering the open end of the insulating container; a flexible gas-tight inner container positioned within the interior of the thermally insulating container for receiving the liquid and for being collapsed into a flat state as liquid is dispensed from the inner container; a connecting piece mounted on the inner container and a tube connected to the connecting piece for dispensing liquids from the inner container, said covering means being oriented downwardly during dispensing of the liquid from the inner container; a channel formed in the covering means and extending between the interior of the insulating container and the exterior of the insulating container, said tube being removably positioned in and extending through said channel; said insulating container being removably positioned within the interior of the insulating container; and an air pipe extending through the covering means from the interior of the insulating container to the exterior of the insulating container for venting the interior of the insulating container.
Claim 3
Dependent Claim
60 words
An apparatus according to claim 1, wherein the air pipe extends from the covering means to a side on the interior of the container located opposite the covering means so that said air pipe terminates in an upper region of the interior of the insulating container when liquid is being dispensed through the tubal with the covering means facing downwardly.
Claim 4
Dependent Claim
13 words
An apparatus according to claim 2, wherein said covering means is a lid.
Claim 5
Dependent Claim
53 words

Claim 6
Dependent Claim
16 words
An apparatus according to claim 2, wherein the tube is releasably connected to the connecting piece.
