Description · |

The innovation relates to a drinking vessel made of glass, a so-called. "Drinking glass".

In the case of the drinking glasses which have become known so far in a wide variety of designs, there is still the disadvantage that the same due to the particularly good thermal conductivity of the glass with temperature-controlled filling heat up or cool down quickly and then only with the formation of sources of accident risk from Users can be recorded / used. In addition, there is temperature adjustment due to the heat exchange an often undesirable change in temperature relatively quickly the contents instead.

The innovation lies in the task at hand, an improved one To create a drinking glass which the user can safely grasp and hold safely even when the product is at a high temperature can be. In addition, a rapid change in temperature in the filled drinking glass should be avoided.

According to the innovation, this is achieved by a drinking glass which is at least partially double-walled in the vessel area, with enclosed isolation space between the two walls, is designed and thus prevents rapid heat exchange between the product and the environment.

This glass vessel, which is open at the top, can therefore also be used Absorption of very hot or very cold filling without disadvantages, i.e. without risk (because of high or low temperatures) touch. It is also ensured that the initial The temperature of the drinking glass filling is maintained for as long as possible - which means a longer dwell time with the desired Temperature is given, so the utility value is increased considerably.

The newly designed drinking glass is suitable for both very hot and very cold drinks.

In a particularly preferred embodiment, there are two Individual glasses of different sizes forming cavities joined together, the cavity in particular filled with air and both individual glasses welded together at their edges.

A drinking glass designed in this way has a simple structure and is safe to handle. Because of ultimately a workpiece Formative design, it can be used safely (grasped, turned over) and cleaned. The air chamber represents a simple, safe and inexpensive insulating means, so that also ensures inexpensive production is. Because of the clamshell training and intermediary A layer of air can also be used with thin-walled glass without a filling with a large temperature difference room or ambient temperature risk of breakage due to external influences, e.g. due to incorrect behavior d. User (s), exists.

The drinking glass according to the invention with insulating properties can be designed both in stem and cup shape.

Further features of the renunciation are the remaining subclaims refer to.

The subject of the innovation extends, not just to that Features of the individual claims, but also on their combination.

The drawing shows exemplary embodiments of the innovation and are explained in more detail below. Show it :

Fig. 1 is a partially sectioned side view of a stem-shaped nexation-compliant drinking glasses with insulating container space (cup part) and

Pig. 2 shows a partially sectioned side view of a drinking glass according to the invention in the form of a cup stable floor construction.

A drinking glass 1 according to the invention according to Pig. 1 is in stem shape executed and has a stalk fxiß 2 provided Outer glass 3, in the cup part 4 with the interposition of a preferably air-filled insulating space 5 Cup-like inner glass 6 inserted and in the upper edge area by melting the two individual glasses 3, 6 closed are connected to one another in a single unit.

This drinking glass 1 is thus double-shelled, i.e. designed as a double-chambered glass in the usable area.

In the erectable hollow glass body, another hollow glass body serving to hold the drink is inserted in such a way that that in between the insulating cavity remains.

The inner glass 6 is preferably in the cup part 4 of the outer glass 3 hung. For this purpose, the inner glass 6 is formed in the upper edge area so that it extends approximately obliquely or executed in a manner not shown in a brim-like / bead-forming manner.

A particularly advantageous arrangement and load absorption is . ··. . ",.". . ".: ·"""'.'"/ 7

before, if the contact surface between the two individual glasses (items 3, 6) is not too small, i.e. more than shows only linear system. The outer and inner glass 3, 6 are therefore in a preferred and advantageous manner at the top widened outwardly in a cone-like manner and grasp on a greater distance (length) with their jacket wall, in particular with a holding and / or connecting edge numbered 7/8 (which also takes on an adjustment function) into each other. At least the upper (outer) end of these wall parts is welded.

It is advantageous for the holding and / or connecting edges 7, 8, which are turned outward, to make it easier to empty the glass To design tilting edge. The upper edge of the drinking glass can be chamfered / rounded der Glaswandimg at least one of the two individual glasses (Pos. 3, 6) be designed so that the impression of a thin-walled There is a drinking glass - the double wall that actually exists is then not perceived, at least not perceived as disturbing.

The two individual glasses are shaped in the area of the receiving or beaker area in such a way that one enlarges towards the bottom Distance between the same and thus also an increase in the insulation space strength results (see drawing.). In a preferred embodiment, the bottom of the inner glass 6 tapers towards the bottom, in particular is designed to be concave.

The wall thicknesses of both individual glasses can be equally strong, at least in the cup area.

Crystal clear or colored and / or at least partially structured glass can be provided. If necessary, can the inner glass 6 have a mirror coating.

Instead of being welded together, an adhesive connection can also be used . ■ · .. ·· .. ·· .. ■■.: ■■ ·: "■:" · / 8

Furthermore, with a certain modification of the design provide a plug or screw connection. If necessary, an additional connecting element, e.g. a connecting ring ai; s metal, plastic or the like. for use reach. In any case, the finished drinking glass acts, at least in its use form, as an object (i.e. a unit) .

The execution according to i'ig. 2 corresponds to in the cup area in Basic principle of the construction described above according to FIG. 1.

This cup version of a drinking glass according to the invention with insulating properties is numbered 9 and differentiated essentially through a stable base area, a base part 10 instead of handle base 2. The cup base can show the most varied of shapes.

The cup-shaped version of a drinking glass according to the innovation also makes it possible in a simple manner that only the jacket wall of the vessel part has two shells - with in between lying isolation room 5 - is executed.
