Description

~ Z - '| The present invention relates to an article of goblet namely, drinking glasses, goblets, etc., of pre-! glass case with marked 'refrigeration or thermal accumulation' properties.

The most common way to drink cold drinks today is to use ice cubes that are introduced into the drink. Taking into account that in certain particular cases, the ice cube by melting dilutes the drink, one uses "false ice cubes" which are constituted by a matter other than water which is put to refrigerate and which restores by a simple phenomenon d exchange the frigories the drink in which they are introduced.

The effectiveness of these "fake ice cubes" is however reduced and it is important that the drink itself before being poured, has itself been properly refrigerated.

A number of users also fear using ice because they are not assured of the nutritional quality of the water that has been used to make such ice.

The present invention aims to remedy these drawbacks by providing a article of gobletry of any shape suitable for cooling or if necessary heating the drink which is poured into it.

According to the invention, said article of gobletry which will be qualified hereinafter generally by the expression "glass" but which can of course affect another form such as a cup, a bowl, a mug -, etc. has a double sealed envelope which contains a liquid playing the role of thermal mass, which can be cooled or if necessary heated, in order to cool or heat the liquid which will be poured into it / during its use.

Advantageously, said article is made essentially of glass; however, other materials can be considered.

It has been observed that if the double envelope extends over the entire height of the glass, the thickness can be inconvenient during use. To remedy this drawback, the double envelope does not extend over the entire height of the glass and in particular does not extend over the rim, that is to say the area where the lips are worn. . It is therefore understandable that according to the invention, the glass consists of a double envelope covering its bottom and practically the entire height of the glass except for the rim. The drinking can be formed itself by the extension of either the inner envelope or the outer envelope.

Appropriate means are provided for hermetically sealing the double envelope, during manufacture, after it has been filled with a material playing · .the role of adequate thermal · mass. Such a sealing can be carried out by glassmaking techniques by fusion or by gluing using glues suitable for the trades used. The product having a high capacity for absorbing calories or frigories can be one of the products usually used for this purpose, such as ethylene glycol and the like. In general, it is advisable not to completely fill the double envelope and to leave sufficient space to allow expansion under the effect of heat.

The use for water cooling purposes is not recommended due to the well known characteristics n of expansion under the effect of a lowering of temperature

j The most common use of the glass which has just been described is of course to keep drinks cold or even iced. For this purpose, the glass is previously stored in a cabinet, a refrigerator specially adapted to the shape of the glass. . Such refrigerated cabinets include housings suitable for receiving glasses of corresponding shape and the glasses are left there sufficient time so that the product contained in the double jacket is practically in equilibrium with the temperature of the refrigerated cabinet, Depending on the use provided, the refrigeration cabinet can be designed to receive, for example, half a dozen, a dozen or several dozen glasses. The most obvious use is of course the use in bars, cafes, etc., which are required to distribute cold drinks. The shape of the glass is of course largely arbitrary and for example, when considering using it for beer, it may be a mug: with a handle. In this case, adequate cutouts are provided in the housings of the refrigeration cabinet to receive said handle. Advantageously, one or more loops of a refrigeration circuit are provided below the housings intended to receive the glasses, so as to surround them when they are put in place in the refrigeration cabinet. The refrigeration cabinet itself can be fitted with thermostat adjustment knobs, a rapid refrigeration device, a defrosting device, all of these means being known per se for different refrigeration installations which do not require any particular description. .

A possible use of the device of the invention of course also consists in keeping drinks hot and for this purpose it is advisable to keep the glasses for a certain time in for example a double boiler which would cause the accumulation of calories in the product contained in the double envelope.

It should be noted that a particular advantage of the glass intended to keep drinks cold is the fact that the mass of the liquid contained in the double envelope can in certain cases be sufficient so that all the accumulated frigories have not been consumed after the use of glass.

It then suffices to rinse or even to quickly wash it hot and to replace it in the refrigerated cabinet where it can be quickly brought back to its lowest temperature by taking advantage of the stored frigories which were not total-} consumed.

As indicated above, the shape, volume and material of said items of plumbing are largely arbitrary. It should also be noted that these items can be decorated as desired. This is how it is possible in particular to provide a metal or other ring at the level where the double jacket stops to leave only the area of the rim free and thus cover the area where the sealing of the double is generally carried out. envelope. This ring but also any other surface of the article may include decorations, advertisements, etc.

In order to ensure good stability of the glass, it is generally advisable to provide that the double envelope has a greater thickness in the level of the bottom than on ^ 3 ί '- 6 i;

Side wall islands. Thus, while ensuring the stability of the glass, it is ensured that there is a sufficient volume of product in the double envelope to effectively refresh the drink which will be poured into it.

In order to better describe the invention, reference will usefully be made to the appended figures given by way of illustration without limitation.

In the drawings: - Figure · 1 shows a view of a glass; glass designed according to the principles of the invention; - Figure 2 shows the adapted refrigeration cabinet - Figure 3 an enlarged view of part of Figure 2.

According to the invention, the glass consists of a double envelope 1, 2 extending over the major part of the side wall of the glass and also on the bottom of the latter. This double envelope is hermetically sealed at its upper part 3 by any suitable means such as heat sealing or bonding, after it has received a sufficient volume of an adequate product 5, ethylene glycol or the like. The product does. however, does not fill the entire double envelope and a space 7 is provided to allow the product to expand. As indicated, the drink 9, that is to say the upper part of the glass where the lips are worn, exceeds the height of the double envelope and is constituted by an extension of the envelope.

Different shapes can be provided, for example a glass with a handle. At the level of the hermetic sealing zone 3 and the expansion space, it may be advisable to surround the assembly with a ring 11 which gives an elegant finish to the assembly and which plus can hide any traces left by the seal 3 and the empty expansion space 7, if desired.

Since the product 5 contained in the jacket is generally a liquid, it can be colored. Certain dyes having colorations which vary according to the temperature can in particular be used so that it can be determined precisely whether the glass and in particular the product contained in the double jacket has been reduced enough to ensure sufficient refrigeration capacity taking into account the volume and the temperature of the liquid which will be poured into the glass.

The glasses which have just been described are in principle, for refrigeration purposes, which are the most common purposes, stored in a refrigeration cabinet such | as shown in Figure 3. As will be noted, this refrigeration cabinet bearing the general reference 20 com-I carries a series of cells 22 of shapes corresponding to those of the glasses for which they are used. Under the honeycomb plate 24, refrigeration coils for the glasses are arranged. It may be advantageous if the ar-ί I moire is closed by a cover or the like when not in use. The invention extends to this object.

The various elements of a refrigeration installation are well known and therefore do not require any additional description, it being understood that it can be either a compressor installation or an absorption installation.

As indicated in FIG. 2 and in more detail in FIG. 3, the glass 1 is preferably placed in the refrigeration cabinet with the bottom 32 upwards, resting on spikes 33. In this way, if the glass is returned wet in the refrigeration cabinet, it does not adhere to a wall thereof under the effect of freezing and it can be easily removed from the refrigeration cabinet.

Although particularly preferred forms of use of the invention have been described, it should be understood that it is not limited to the description which has just been made and that many variants and modifications can be made both to articles of gobletry and to refrigeration cabinets for them, while remaining within the scope and in the spirit of the invention The invention can be used for domestic use or in bars, cafes, restaurants , hotels, clinics and ^^ hospitals, f · /; λ î i '?
