Problems solved by technology

[0003] A disadvantage of this beverage preparation machine is that the prepared hot beverage cools down quickly
In addition, there is the risk that the glass container will break due to incorrect handling and thus allow the hot liquid contained therein to escape and scald the user
This can have very serious health consequences

Embodiment Construction

[0029] figure 1 A perspective view of a glass container according to the invention is shown. The container comprises an inner part 1 and an outer part 2 .

[0030] The inner part 1 is substantially cylindrical and comprises a base 10 and a surrounding side wall 11 .

[0031] The base 10 is arranged in the lower region of the inner part 1 . The base 10 is connected to the side wall 11 via a transition 14 , here designed as a rounded transition 14 . The side walls 11 extend perpendicularly to the base 10 and are cylindrical. The upper edge 15 of the side wall 11 ends in an upper region. The bottom 10 and the side walls 11 define a cavity 12 . The cavity 12 is used to accommodate liquid. Furthermore, an outflow opening 13 is formed in the upper region. The spout 13 is designed such that the beverage can be removed as little as possible with the formation of droplets.

[0032] The outer part 2 is likewise designed to be substantially cylindrical and likewise comprises a ba...

Abstract

The invention discloses a glass vessel for a beverage-making machine, which glass vessel is at least partly of double-walled design. In a first refinement, an inner part (1) projects beyond an outer part (2) which partly surrounds said inner part, with the result that a double-walled lower region (100) and a single-walled upper region (101) with a pouring region (13) arranged therein are provided. In another refinement, the inner part and outer part are connected at their upper edge, and the pouring region is of double-walled design. The invention also specifies a method for producing the vessel.

Description

technical field [0001] The present invention relates to a glass container for a beverage preparation machine. Background technique [0002] So-called "French Press" coffee preparation machines are known from the prior art. The coffee maker typically has a tall cylindrical glass container and a push rod filter movable within the glass container, which is pushed down in the glass container by a piston rod. To prepare coffee, the container is filled with ground coffee and brewed with hot water. Let the mixture sit for a few minutes. Then push the push rod filter down. As the plunger filter carries the coffee grounds to the bottom of the container, it separates the leached coffee grounds from the brewed coffee beverage. Tea and the like can also be prepared in a similar manner. [0003] A disadvantage of such beverage preparation machines is that the prepared hot beverage cools down rapidly. In addition, there is the risk that the glass container will break due to improper...
