Abstract

The invention concerns a tasting and drinking glass in particular isothermal enabling tasting as well as drinking beverages and other food products in optimal conditions. Said tasting and drinking glass (1) comprises an outer cup (2) mounted on a stem (4) and an inner cup (3) having on the periphery of its external surface a shoulder (9) resting on the outer cup (2) upper edge to form a joining line (16), a free space (17a) being provided between the two cups. The invention is characterised in that the height (H) between the shoulder (9) and the inner cup (3) bottom (13) is strictly smaller than the outer cup (2) height (h) such that the inner (3) and outer (2) cups have as only contact points said joining line (16). The inner cup (3) bottom comprises bulges (14) to promote the release of aromas and ethers. Moreover, the cups (2, 3) have shapes and dimensions designed to obtain maximum aromatic and gustatory expression.

Description

TASTING AND CONSUMER GLASS

The present invention relates to a tasting and drinking glass comprising an outer cup mounted on a foot and an inner cup having on the periphery of its outer surface a shoulder resting on the upper edge of the outer cup to form a junction line, the external width of the internal cut below the shoulder being less than the internal width of the external cut so as to form a free space between the two cuts.

This type of double-walled glass is used to contain drinks which must be kept at a certain temperature, the free space provided between the two cups constituting an insulator. Such a glass is known from the French utility certificate no. 2,709,652. The bottom of the inner cup of this glass also has a boss which rests on the bottom of the outer cup. This boss is intended to obtain good support for the interior cut and to constitute a point of sparkling. The disadvantage of this boss is that it increases the duration of glass production. It also constitutes a heat conduction zone between the outer cup and the inner cup, hence poor maintenance of the temperature of the drink contained in the glass.

In addition, it has a narrow shape, not suitable for containing food products which must remain at constant temperature such as ice cream or sorbets. This shape also makes the glass particularly difficult to clean and dry.

Also known from American patent US-A-1,968,263 is a glass comprising an inner wall and an outer wall which are joined at the top by a rim. This means that the lip where the lips are placed is very thick and is therefore not pleasant for the consumer.

On the other hand, these glasses or any form of known glass do not allow to restore the taste and olfactory qualities of drinks such as wines, brandies. beers, fruit juices, Champagne, sparkling water, etc., during their tasting. The present invention aims to overcome these drawbacks by proposing a particularly insulated tasting and consumption glass allowing the tasting as well as the consumption of drinks and other food products under optimal conditions.

For this purpose, the invention relates to a tasting and drinking glass of the kind indicated in the preamble, characterized in that the junction line is distinct from the upper edge of the glass and in that the height between the shoulder and the bottom of the interior cut is less than the height of the exterior cut so that the interior and exterior cuts have as their only contact points their junction line.

In a particularly advantageous manner, the bottom of the interior cup may include domings to promote the release of aromas and ethers.

Preferably, each of the sections has walls of substantially rounded shape so as to obtain a balloon glass. In addition, the diameter of the inner cup decreases towards the upper edge of said cup so as to keep the aromas and let the ethers escape.

Preferably, the inner cut has an inner diameter substantially equal to 72 mm at its upper edge and an outer diameter substantially equal to 1 17 mm at the shoulder.

Preferably, the glass according to the invention has a height substantially equal to

170 mm. the height of the balloon formed by the two cups being substantially equal to 90 mm, in order to be able to hold the glass in a balanced and professional manner for tastings and consumption.

Preferably, the external and internal sections have a thickness of between 0.5 and 2 mm near their upper edge, and preferably substantially equal to 1 mm, and between 0.5 and 2 mm at their bottom, and preferably substantially equal to 2 mm. The present invention and its advantages will appear more clearly in the following description of an exemplary embodiment, with reference to the appended drawings, in which:

FIG. 1 represents a perspective view of a glass according to the present invention,

FIG. 2 is a perspective view of the interior section, and

- Figure 3 is a perspective view of the outer section.

Referring to the figures, the glass 1 comprises an external section 2 and an internal section 3 nested in the external section 2. The external section 3 is mounted on a foot 4, comprising a rod 5 and a base 6. The foot is formed of known manner by drawing the hot glass. The rod 5 has a diameter substantially equal to

8 mm and the base has a diameter substantially equal to 80 mm.

The outer section 2 has a curved circular wall 7 and a bottom 8 slightly curved at the level of the rod 5. The wall 7 has a thickness substantially equal to 2 mm at the bottom 8 and substantially equal to 1 mm near the upper edge 10 of the outer section 2. The bottom 8 also has a thickness substantially é ~ gtsa ^u le to 2 mm.

Referring more particularly to FIG. 2, the internal section 3 has on the periphery of its external surface a shoulder 9 of sufficient width to be able to rest on the upper edge 10 of the external section 2. The external diameter of the internal section 3 at - below the shoulder 9 is less than the inside diameter of the outer cup 2. Thus, a free space 17a is formed between the two cuts when they are assembled to give the glass 1. This free space is thermally insulating because the formation of an air vacuum in this space when the glass cools after being produced by gluing or hot welding.

The wall l ia of the inner section 3 located above the shoulder 9 is curved at substantially the same curvature as the wall 7 of the outer section 2. Thus. when the two cups 2 and 3 are assembled, a glass 1 of balloon shape is obtained. The outer diameter D of the inner cup 3 is equal to that of the upper edge 10 of the outer cup 2 so as to give a glass 1 with continuous walls. The arc of curvature of the wall l ia is such that the internal section 3 has an internal diameter d substantially equal to 72 mm at its upper edge 12 and has an external diameter D substantially equal to 117 mm at the level of the shoulder 9.

The bottom 13 of the inner section 3 includes two bends 14 whose function is described below.

On the other hand, the height H between the shoulder 9 and the lowest point of the bottom 13 of the interior cut 3 is less than the height h of the exterior cut 2, the height of h being defined as the distance between the upper edge 10 and the lowest point of the inner face of the bottom 8. Thus, the bottom 13 of the inner cut 3 is absolutely not in contact with the bottom 8 of the outer cut 2 so as to create a space 17b entirely free and insulating under the inner section 3. The only points of contact between the two sections are formed by the junction line 16 at the level of the shoulder 9.

The wall 11b located below the shoulder 9 has a thickness substantially equal to 2 mm at the bottom 13 of the inner section 3 while the wall 1a has a thickness substantially equal to 1 mm near its upper edge 12. The bottom 13 also has a thickness substantially equal to 2 mm.

The internal section 3 may also include lines 15 to mark the capacity of the glass according to the legal doses. For example, the line corresponding to 25 cl, the line corresponding to 55 cl which is located at the level of the junction line and the maximum capacity line at the highest point may appear.

The glass 1 is obtained by assembling the sections 2 and 3. It has a total height of 170 mm, the height of the balloon formed by the two sections being substantially equal to 90 mm.

Glass 1 according to the present invention exhibits exceptional tasting qualities. Indeed, the particular dimensions and the rounded shapes of cups 2 and 3 make it possible to obtain a balloon glass 1 with a sufficient opening to have a good evacuation of certain volatile compounds which are found in wines and spirits (ethers , volatile acids, etc.) and which often disturb the detection of the so-called "noble" aromas of these drinks. The opening is also wide enough to allow the taster to insert his nose into the balloon and thereby capture a maximum of aromas. On the other hand, thanks to the sufficiently rounded shape of the balloon, the heavier aromas remain enclosed in the glass. We obtain a more balanced and more marked taste which the consumer can fully benefit from.

In addition, due to the two bulges 14 provided on the bottom 13 of the inner cup 3, a wave is created when the wine is stirred at the bottom of the glass so that the aromas and the ethers are released more easily in relation to to other tasting glasses. The glass according to the invention will therefore be more efficient for competitions and experimental stations.

In addition to the best aromatic expression, the glass 1 according to the invention also provides many taste qualities. In this case, a wine will keep its flavors on the palate, its persistence and its body longer. Also, sparkling wines (Champagne, Crémants, etc.) benefit from a more regular and more lasting petulance.

The shape of the glass is also studied for the sake of aesthetics, the elegance of a large tasting glass being more than important during its use. Likewise, this glass will decorate a table with great aesthetics.

On the other hand, the insulating free space 17a, 17b formed between the two cups 2 and 3 makes it possible to obtain a double-wall insulated glass 1 which can be used to maintain wines or other alcohols for a long time at a certain temperature. than other drinks or dishes such as fruit juices, beers, waters, coffees, infusions, teas or ice creams and sorbets, caviar, etc.

Thanks to the insulated walls, the contents of the glass, which can be as much hotter or colder than the ambient air, will keep its temperature longer. This allows the consumer to take his time to taste and quietly enjoy the contents of his glass. Consequently, wine for example can be served at a lower temperature, or lower for coffee, the risk of heating or cooling the contents of the glass almost no longer existing. The product poured into the glass can therefore be appreciated in optimal conditions as soon as it is served.

In addition, due to the double wall, the temperature difference between the inner cup 3 and the ambient air is not a source of development of fogging, which gives a major advantage to tasting, since the consumer can mirror the robe of the wine or liquid contained. This advantage also brings a significant aesthetic quality.

Of course, glass 1 is also perfectly suitable for tasting and consumption under optimal conditions of drinks or dishes at room temperature, such as liqueurs, glass 1 making it possible to obtain maximum sensory expression.

Due to its dimensions, the glass according to the invention is robust. In addition, its wide opening allows easy cleaning and drying, minimizing the risk of breakage. It can therefore be used both by professionals and by individuals and can in particular be washed in a machine.

The glass according to the invention is preferably made of lead-free crystal since lead is toxic.

The present invention is not limited to the embodiment described but extends to any modification and variant obvious to a person skilled in the art. In particular, the dimensions can vary according to needs while respecting the appropriate proportions to safeguard the tasting qualities of the glass.
