    Double-walled drinking glass (1) made of borosilicate glass, which is filled in the cavity with a phase change material (PCM) (3). The double-walled glass has an outer wall (2) and an inner wall (6), wherein between the inner wall outer surface and outer wall inner surface is a cavity (3, 4) and a connecting region (5) which connects the outer wall (2) with the inner wall (6). The cavity (3, 4) is filled with a PCM (3) and also contains a gas cushion (4), which compensates for the density difference of the PCM (3) from liquid to solid and solid to liquid.

    description
    Subject matter and technical field The invention relates to a double-walled drinking glass of borosilicate glass which is filled in the cavity with a phase change material (PCM).
    PRIOR ART Various patents are known which relate either to applications with PCM or to special designs of glasses. In the following, a small excerpt: In DE 10 2004 025 994 A1, latent heat accumulators for wall elements and in DE 20 2005 008 406 U1 transparent hollow building blocks with latent heat accumulator are treated. The effect of phase change materials is used.
    DE 20 2007 001 699 U1 describes the invention of textiles with increased capacity for latent heat storage for bedding. Processes for the production of such textile fibers are described in DE 10 2008 031 163 A1, which deals with hollow fiber filled with latent heat storage material (PCM), its method of preparation and its use.
    EP 2 586 341 A1 describes a double-walled drinking glass and method for producing a printed drinking glass. In DE20103678U1 a drinking glass with heat storage for cold and hot drinks is described, which uses sensible heat for energy storage by a heat-absorbing gel.
    DESCRIPTION OF THE INVENTION The present invention relates to a drinking vessel made of glass (drinking glass) into which drinks are filled and from which people drink directly. The drinking glass has the property of cooling drinks without diluting them by utilizing the latent heat of a phase change material (PCM). Furthermore, the glass has the property of changing the phase of the PCM from liquid to solid and solid to liquid to change the transparency resulting in a change in the appearance.
    List of Drawings The invention will be explained in more detail with reference to an exemplary embodiment, which is illustrated in the drawings. It shows:
    Fig. 1: Double-walled drinking glass with PCM, three-dimensional sectional drawing Fig. 2: Double-walled drinking glass without PCM, normal projection
    Embodiment of the Invention The drinking glass is a double-walled glass made of borosilicate glass, thus has an outer wall (2) and an inner wall (6), wherein between the inner wall outer surface and outer wall inner surface is a cavity (3, 4) and a connecting region (5) the outer wall connects to the inner wall. The cavity (3, 4) is filled with a PCM (3). In addition, the cavity (3, 4) contains a gas cushion (4) which serves as an expansion element and compensates for the density difference of the phase change from liquid to solid and solid to liquid.
    The in the cavity (3, 4) contained PCM (3) changes its state of matter from liquid to solid while staying at a lower temperature than the phase change temperature. Conversely, the PCM contained in the cavity changes its state of aggregation from solid to liquid while staying at a higher temperature than the phase change temperature.
    By changing the state of aggregation, the transparency of the product changes, resulting in a change in the appearance.
    By changing the state of aggregation, the latent heat (stored phase change enthalpy) from solid to liquid is used to cool drinks. The effect of cooling a beverage is usually realized with water ice, which dilutes drinks.
    The invention combines both the advantage that drinks can be cooled without diluting and changes the transparency of the product by melting and crystallizing the PCM (3).
    By varying the PCM and glasses can be made to keep drinks warm.
