The invention is particularly useful in the context of a glass of the type described in particular in the patent FR 2 940 898, the same applicant.

It relates to a drink glass, of the type comprising a rotationally symmetrical parison around a vertical axis Z, comprising inside said parison a set of at least two internal ribs regularly distributed on the periphery of the parison, each extending substantially along a generatrix of the parison, substantially from the bottom of the glass, to a height of the parison less than a normal filling level of the glass, different for at least two of these internal ribs. In the variant used in the context of the present invention, the glass is cup-type having no leg, but the bottom of the parison also serves as a support zone. To do this, it has a much thicker parison in the area of the bottom of the glass. It has three internal ribs, extending from the bottom of the glass to different heights, the largest extending substantially to the maximum diameter level of the glass.

The genesis of this project is to be able to transform a glass cup 36cl, in a function of glass tasting foot, allowing to have the possibility of another solution on the setting table according to his desires and tastes. The 36cl cup is optionally equipped with different legs and feet that can be made in all kinds of materials such as precious wood (markers), metal, plastic, stone, etc.

To meet the specifications of industrial manufacture, the grip of the modified glass can be achieved by the leg or the foot of the glass instrument.

The modified glass is made of several different parts, as follows:

- a cup parison with the system of three separate blades inside the glass,

a male, threaded, intermediate piece, fixed under the cup,

- one leg or a threaded handle, screwed onto the intermediate piece,

- one foot, either hot-welded, screwed on the leg, or attached to the intermediate piece, depending on the type of drink for which the glass will be used.

1 / The parison:

As seen in FIGS. 1 and 2, parison 1 is, in the present nonlimiting example, a cold cut glass cup, with a capacity of 36cl (but any other capacity is conceivable), made of an ecological material. , without lead oxide, but with minerals, unalterable over time, even intensive industrial washes, extremely brilliant, unalterable over time and very resistant to the shocks of life. The parison 1 of the glass according to the invention can be made of crystal, glass with or without minerals, crystalline or in another material, preferably without lead oxide.

The cup produces an accelerating effect of aromas, by means of three helices 2a, 2b, 2c, in relief, in the form of sharp edges, on the periphery and at the bottom of the parison of the glass. The propeller blades are asymmetrical and the angular spacing between them is the same, allowing a mixture and a homogeneous exchange of the wine (or any other drink contained in this glass) and, in this way, a better aromatic development.

By turning the glass, in a circular fashion, with the wine or any other liquid, inside, the molecules of the wine are triply jostled, allowing to mitigate the vapors of alcohol. Driven by the propeller blades 2a, 2b, 2c, which oxygenate the liquid three times, they accentuate the phenomenon of exchange and homogeneity of the drink. Thanks to this, the glass optimally works the three aromatic layers of the wine, for example, present in the parison of the glass.

^* Primary, volatile, light, fruity and floral aromas found in the upper part of parison 1 between the highest level of wine and the end of the glass known as buvant 3.

^* Secondary aromas, fruit, land, located in the center of the chalice.

^* Tertiary aromas at the bottom of the parison 1 where alcohol and wood scents are found.

The three separate propeller blades 2a, 2b, 2c are calibrated, in order to prevent regulatory aspects related to alcohol: to encourage people to drink less, but better: the highest propeller blade being calibrated to be about half of the parison. The smallest is calibrated for strong alcohols.

Under this action, the propellers 2a, 2b, 2c accentuate the phenomenon of exchange and homogeneity of the drink.

When the parison 1 is positioned with the rim 3 down, for washing machine for example, the water can not stagnate on the bottom of the glass.

- Paraison 1 of 36cl in roundness closed with the drink 3, very adapted to the tasting, to preserve the aromas of the wine or any other drink. The cup thus described is in the spirit of the glass described in patent FR 2 940 898, without its leg, foot and dome.

The intermediate piece 4 made of PMMA, SAN or ABS + PC (see FIG. 3): An intermediate piece 4, symmetrical of revolution about a vertical axis Z, is fixed under the parison of the glass, coaxially with the parison 1.

This intermediate piece 4, of the male type, is here made of PMMA (polymethyl methacrylate), SAN (Styrene-Acrylonitrile Copolymer) or ABS + PC (Acrylonitrile-Butadiene-Styrene + Polycarbonate). It is transparent, so as to remain as little visible as possible. It is threaded on its outer face 5.

A mold with a drawer system is provided to obtain an intermediate piece 4 flawless, aesthetic, functional and with good tolerances.

The fixing of the intermediate part 4 on the glass 1 is carried out by gluing, between the bottom (flat part) of the parison 1 and the widest upper part 6 of said intermediate part 4. An extra strong glue is used here, for example example of the trademark 3M -marque dépôt-, for example or of another brand, which resists:

- the tearing off,

- intensive industrial washes (typically at least two thousand washes) and household,

- UV (duration 5 years minimum),

- at the microwaves,

- the color changes of the said glue (duration 5 years minimum),

- And can erase the defects of the upper part 6 of the intermediate part 4 in contact with the glass 1.

Gluing takes place under and over the widest upper part of the machined part in PMMA, SAN or PC ABS by producing a circular bead or stud. For this purpose, the intermediate piece 4 comprises on its upper face a hemispherical gluing sealing lip of 0.15 mm radius, disposed along the edge of this upper face. In the present nonlimiting example, the intermediate part 4 comprises a trapezoidal thread of 38 mm with a pitch of 4 mm allowing an optimal tightening of about one turn, to limit, thus, the number of rotations without having to turn a complementary female part too long.

Alternatively, the intermediate piece comprises a thread with ratchet mechanism at the end of the thread, that is to say a position-secure holding by stainless steel ball screw fixed in the leg, the ball being housed in a hemispherical footprint provided on the joining piece in PMMA, SAN or ABS + PC. This mechanism allows a tightening of three quarters of a turn followed by a snap of the foot into the clamping piece, to facilitate the perception by the user of a correct tightening of the foot on the parison and reduce the risk of unintended unscrewing, a known minimum force to be applied to overcome the ratchet return force.

As seen in the figures, the intermediate piece 4 has an upper face 6 whose diameter is substantially equal to that of the flat portion of the lower face of the parison 1.

In the present nonlimiting exemplary embodiment, the intermediate piece 4 has, beneath the edge of its upper face 6, a beveling 7 whose angle is equal to the local slope formed by the envelope of the parison with its flat underside . In this way, a visual continuity is obtained between the parison 1 and the intermediate piece 4.

The diameter of the threaded portion of the intermediate piece 4 is, in the present example corresponding to a parison of 80 mm diameter and 90 mm high approximately, 34 mm, for a thread height of 5 mm and a thread depth 2 mm. These dimensions are determined by the weight of the parison 1 when filled with liquid. They must be sufficient to ensure the mechanical strength of the thread in shear when the glass is tilted. 3 / The leg (see Figure 4) or handle (not shown in the figures):

The leg 8 can be made of different materials:

- precious wood

- Zamak type metal, stainless steel, etc., - plastic

- stone granite, marble, etc.,

- etc.

The leg 8 forms, in its upper part, a female threaded piece, whose thread is complementary to that of the intermediate piece 4. This leg 8 is screwed on the intermediate piece 4, with a tightening of about one turn, or alternatively a quarter-turn tightening followed by a detent, as described above.

4 / The foot (see Figure 4):

The foot 9 is normally flat below the bottom or may optionally be in the form of a helix with 3 isostatic points below it.

The material used can be:

- precious wood (markers)

- Zamak type metal, stainless steel, etc.,

- plastic

- stone granite, marble, etc.,

- etc.

The fixation of the foot 9 on the leg 8, during manufacture, is carried out according to the material used, either by screwing, by welding, or by machining in a single block with the leg 8.

On the other hand, for a whiskey-type glass, for example, the foot 9 has a female thread complementary to that of the intermediate piece 4, on which it is fixed directly.

For a MUG, teacup, coffee cup, the handle will be attached directly to the intermediate piece 4, because the underside of the handle will serve as a foot.

The process for making glass with a foot then comprises the following steps:

Realization of the cup 1 by a mechanical machine type method, comprising, in the present non-limiting example, a step of creating the parison 2 in a fixed puff mold,

Gluing of the intermediate piece 4 male, Taking glue,

Screwing the leg 8 and / or the foot 9 onto the intermediate piece 4.

Alternatively, the glass can also be made by mouth blown.

In another variant embodiment, the intermediate piece 4 is made in one piece with the parison 1.
