Description

Drinking vessel with cooling element

The invention relates to a drinking vessel with a closed chamber in which a cold storing medium is arranged. The invention also relates to a cooling device for the provided in the chamber of the drinking vessel cold accumulating medium.

Drinking vessels are of course well known. It is also known to cool drinks in drinking vessels. For example, ice cubes are added to a drink in a drinking vessel. The disadvantage of cooling by ice cubes is that the beverage is diluted in the course of cooling by thawing the ice and the ice cubes are not reusable. Also known reusable ice cubes from a plastic shell with water filling, however, are very complicated to use, since each single cube must be cleaned after use, dried and frozen again. Another disadvantage of the use of ice cubes for cooling drinks is that the ice cubes claim a significant proportion of the filling volume of the drinking vessel, which is no longer available for the T rinkflüssigkeit in their use.

There are also known bivalve drinking vessels with a circumferential in the lateral outer wall cavity in which already filled drinks cooled by the cold-insulating side wall slowly warm up than in comparable drinking vessels without insulating wall. A disadvantage of this type of cooling is that the drink itself is not cooled, but only its warming is slowed down.

It is also known to use conventional, pre-cooled in the refrigerator or refrigerator drinking vessels for cooling drinks. The disadvantage of using pre-cooled conventional drinking vessels is that the pre-cooled drinking vessel heats up quickly to the ambient temperature.

Object of the present invention is to provide a T rinkgefäß which causes a prolonged cooling time of the filled beverage, it is easy to use and is reusable several times.

This object is achieved in its first aspect by a drinking vessel with a closed chamber in a floor in which a cold storage medium is arranged.

The drinking vessel according to the invention has a completely closed chamber in the bottom. The chamber is filled with a medium that can store cold, a so-called Coolant or cooling element. Preferably, the medium is a liquid or gel. The chamber is arranged in or on an interior of the drinking vessel, in which the beverage is also to cool the beverage located in the drinking vessel. The chamber is removable from the drinking vessel.

The present invention has recognized that a T rinkgefäß having incorporated into the chamber coolant has particularly advantageous application properties. It is reusable, easy to clean, and provides a simple and highly effective cooling option for drinks without the need for additional coolant. The coolant has no direct contact with the beverage and does not dissolve and does not dilute the beverage with it. It stays constantly in the chamber.

Preferably, the chamber is partially filled with air and partly with the cold storage medium. The ratio is chosen so that the air is compressed by expansion of the medium by cooling or heating and the chamber still does not break.

It is also conceivable that the chamber is subsequently introduced into the drinking vessel. An inner wall bounding the chamber towards the bottom can be detachably attached to the floor, for example by means of suction cups or the like. be attached. Such training also allows the subsequent installation in an existing drinking vessel.

Preferably, a closure is provided between the chamber and the inner wall of the inner space. The closure secures the chamber to the inner wall and allows the chamber to be detached from the inner wall and later re-attached.

The chamber can be releasably secured by means of a bayonet closure, a magnetic closure or a rubber closure in the inner wall, preferably in the bottom of the drinking vessel.

The chambers are conveniently stackable and so cool in a small space in a freezer compartment. For this purpose, the chambers are preferably square in cross-sections rectangular.

According to an advantageous embodiment of the invention, the filled with coolant chamber is formed in several parts, and a chamber is permanently integrated in the ground and / or has extensions in the side wall of the drinking vessel. Another chamber is interchangeable provided in the interior and fastened there by means of a releasable closure. Thereby, the inner surface of the drinking vessel, which is disposed immediately adjacent to the chamber, increased and the cooling effect of the coolant to the drink in the drinking vessel amplified.

The replaceable chamber may be in the form of an ice cube or otherwise. It can also be provided only a replaceable chamber and no permanently arranged in the bottom chamber.

According to a further embodiment, the extension of the chamber in the side wall extends at least partially to at most half the height of the side wall. This achieves an increased cooling effect in the lower sidewall region and partially in the upper sidewall region and at the same time provides surface in the upper sidewall region which is not immediately adjacent to the coolant-filled chamber, thereby removing less heat on contact with the user's skin than the lower sidewall region ,

According to a further advantageous embodiment, the extension of the chamber filled with coolant in the side wall of the drinking vessel is annular, so that this annular extension forms a cup shape together with the region of the chamber in the bottom. As a result, the surface provided by the side wall is used particularly effectively for cooling.

According to another advantageous embodiment, the extension of the filled with coolant chamber in the side wall of the drinking vessel on several extensions. Thereby, a visually appealing shape of the chamber filled with coolant can be achieved, and side wall areas for gripping the drinking vessel can be provided, in which no extension of the chamber runs.

According to one embodiment, the coolant in the chamber is surrounded by a shell, which is preferably made of plastic. This makes it particularly easy during the manufacturing process to incorporate the coolant into the drinking vessel. It can be incorporated as filled with coolant pad during the manufacturing process in the molding compound of the drinking vessel.

Conveniently, a vessel wall and / or a vessel bottom are double-walled, and air is trapped between an inner wall and an outer wall. A gap formed between inner wall and outer wall is preferably provided along the entire bottom area of the drinking vessel. The gap can also be formed in the side walls of the drinking vessel and extend at least up to a marked level in the beverage trough.

In particular, in a plastic version of the drinking vessel, the only connection between the inner and outer walls of the opening edge be, which connects circumferentially the inner wall to the outer wall. In this case, then the chamber is conveniently provided in the inner wall at the bottom. The chamber is adjacent the floor outside of the gap.

A layer of air forming in the gap isolates the drink and keeps it cool or warm for longer.

The drinking vessel may be designed according to a variant as a cup without handle. In this variant, the drinking vessel can be stacked particularly easily and, for example, be placed close together for cleaning in dishwashers.

The drinking vessel may be designed according to another embodiment variant as a cup with handle. In this variant, the chamber filled with coolant can run essentially in the entire side wall without the user perceiving the cup as cold when touched on the handle.

According to a particularly preferred embodiment, the drinking vessel is designed as a whiskey glass. In this embodiment, the drinking vessel according to the invention is particularly useful because it causes a long-lasting cooling of the whiskey and whiskey is preferably drunk cool and over a longer period.

The drinking vessel may be made of conventional material such as glass, clay, stoneware or plastic, but preferably of glass. As a result, an easy cleaning of the drinking vessel is possible and the visually appealing arrangement of the filled with coolant chamber visible to the viewer.

The cold storage medium may be conventional coolant. It should have the smallest possible coefficient of expansion. In a preferred embodiment, it comprises propylene glycol and water. Such propylene glycol-water mixtures can be cooled down to -10 ° C. According to another embodiment of the invention, the cold storage medium comprises halogenated alkanes, whereby temperatures of -30 ° C can be achieved. Advantageously, the cold storage medium has a heat capacity which is greater than the heat capacity of the material of the drinking vessel.

Upon melting of the medium, all the heat that is absorbed by the beverage is first supplied as a melting enthalpy of a phase change, without causing a temperature increase. The phase change preferably takes place at temperatures between -5 ° C and 0 ° C in order to achieve a cooling effect of the beverage, but still to keep the drink drinkable and not too cold. Of course, the temperature of the cooled beverage must be above its melting temperature, usually about 0 ° C.

In a further embodiment of the invention, the cold storage medium can also store heat. This makes it an alternative to warming hot drinks such as coffee or tea. For this purpose, the drinking vessel according to the invention with the cold or heat-storing medium in the microwave or in the oven can be warmed up.

In a further preferred embodiment, the coolant may contain dyes. This is when transparent drinking vessel material, such. As glass, a visually appealing design of the glass possible because the colored cooling liquid is visible through the drinking vessel material.

The drinking vessel can be in the form of a glass, in particular a whiskey glass, a teaspoon, a cup or otherwise.

The object is achieved in its second aspect by an aforementioned cooling device with the features of claim 10.

The cooling device is intended to cool down the cold storage medium in the chamber of the drinking vessel. The cooling device is intended for cooling the chambers of the above-mentioned drinking vessels. Conversely, each of the above-mentioned drinking vessels can be cooled by one of the cooling devices described below.

The cooling device according to the invention has a plurality of cooling stations which can be equipped with chambers, which cool each one of the chambers.

In a first embodiment, it is conceivable that the drinking vessels are plugged into the cooling stations together with the chambers containing the cold storage medium, For example, if the chambers are located exclusively in the bottom of the drinking vessel, the drinking vessels can be placed with their bottoms on the cooling places. The cooling stations have electrically operated cooling elements, which cool the cooling medium in the bottom of the drinking vessels.

Particularly preferably, it is provided that the chambers are arranged detachably in the drinking vessel and only the chambers and not the entire drinking vessel are cooled down.

The chambers are inserted with the cold storage medium contained in the chambers in the cooling stations and there, as described above, cooled down by the cooling stations associated cooling elements. The cooling stations can be controlled individually. The cooling element can be cold-sealed with a lid and electrically operated, so that it is not necessary to insert the cooling device in a refrigerator or a freezer.

Fig. 4b shows a cross section through the drinking vessel with inserted removable chamber, Fig. 5 shows a cooling device with inserted chambers.

Fig. 1 shows a cross section through an inventive T rinkgefäß. In a bottom 7 of the drinking vessel, a chamber 1 is arranged, in which the cold storing medium. 2 located. It is also a chamber 1 in the bottom 7 releasably secured by a closure 8. The cold storage medium 2 is surrounded by a shell 3 in this embodiment. The chambers 1 are completely surrounded by the material from which the drinking vessel, apart from the chamber 1, is surrounded. A chamber 1 is in this embodiment in the bottom 7 of the drinking vessel detachable or replaceable and the other chamber 1 permanently arranged.

The medium 2 can be salt water or a gel with a high heat storage coefficient or another medium. The medium 2 leads during cooling in the freezer compartment of a refrigerator so when cooling to temperatures down to -18 ° C, a phase change from liquid to solid. The size of the chamber 1 is dimensioned so that the change in volume of the medium 2 by the phase change or by the subsequent heating does not lead to a cracking of the chamber 1. Therefore, the chamber 1 is not completely filled with the medium 2, but only to a predetermined part. The remaining part is filled with air, which is compressed upon expansion of the medium 2. When melting the medium 2, the total heat is first supplied as a melting enthalpy of the phase change, without causing a temperature increase. The phase change preferably occurs at temperatures between -5 ° C and 0 ° C in order to achieve a cooling effect of the beverage, but still to keep the drink drinkable.

The closure 8 may consist of an extension 1 1 and a recess in the bottom 7, wherein the extension is releasably secured by means of a magnetic closure, bayonet closure or rubber stopper. There are also other closures conceivable.

Fig. 2 shows a cross section through another variant of the drinking vessel according to the invention. In this variant, the permanently arranged in the bottom 7 chamber 1 has an extension 5 in a side wall 4 of the drinking vessel, which is annular and extends approximately to half the height of the side wall 4 of the drinking vessel. Again, the cold storage medium 2 is surrounded by the shell 3, and also here the chamber 1 is completely surrounded by the material from which the drinking vessel apart from the chamber 1. The annular extension of the chamber 1 in the side wall 4 forms together with the region of the chamber 1 in the bottom 7 a cup shape.

The exchangeable, detachable chamber 1 is configured as in FIG. 1.

Fig. 3 shows the side view of another variant of the drinking vessel according to the invention, in which the chamber 1 has a plurality of extensions 6 in the side wall 4 of the drinking vessel. Again, a detachable chamber 1 is provided, but it is not shown. FIG. 4 a shows a drinking vessel according to the invention in a cross section with the bottom 7, in which a recess 9 is centrally placed in the bottom 7. In addition to the drinking vessel, the chamber 1 with an extension 1 1 is arranged. The chamber 1 comprises the stored in their cold storage medium 2. The chamber 1 can be cooled separately from the drinking vessel in a cooling device 12 prepared for this purpose or simply in the freezer compartment of a refrigerator. The extension 1 1 and the recess 9 form a closure 8. This can, as described below, be designed in many ways.

The chamber 1 can have all possible and conceivable outer shapes. It can be configured as an ice cube, but it can also have another figurative design such as a flower, a fish, a geometric shape, etc.

Fig. 4b shows an inventive T rinkgefäß in a cross section with the chamber 1, wherein the chamber 1 by means of a closure 8 in the bottom 7 of the drinking vessel is detachably arranged.

The closure 8 may be a simple rubber closure which allows the chamber to be set in a bottom recess by means of rubber friction, or a bayonet closure. It is also conceivable that a magnet and in the recess of the bottom of a metal plate or vice versa are arranged on the chamber 1, so that the chamber 1 is held by means of a magnetic closure at the bottom of the drinking vessel.

The bottom 7 preferably has the recess 9 and the chamber has the extension 1 1, which is inserted into the recess 9. Recess 9 and extension 1 1 together form the closure 8. It is also a complementary design conceivable.

The wall of the drinking vessel is preferably made of a glass or plastic material. The cooling effect of the drinking vessel is based on the provided in the chamber 1 cold storage medium.

The drinking vessel according to the invention has the advantage that the chamber 1 is removable from an interior of the drinking vessel, and according to FIG. 5, the chamber 1 with the cold storage medium contained in the chamber 1 can be cooled separately.

The chamber 1 may be stackable, for example, be formed in a cross section square or rectangular. The cooling device 12 comprises a plurality of cooling stations 13 for accommodating in each case one chamber 1. The cooling device 12 is operated electrically and has in each case a cooling element at each cooling place 13, which may optionally also be switched on and off individually. The cooling device 12 can be closed with a cover 14. The cooling device 12 makes it possible to cool down the cold storage medium in a simple manner and without an additional refrigerator, so that it can then be locked or secured in the cooled down state as a cold reservoir again by means of the closure 8 in the bottom 7 of the drinking vessel.
