DESC:FIELD OF THE INVENTION:

The present invention is relates to whisky-glasswith baffle system which will eliminate the need of external/additional stirrer. The baffle comprisesstationary parts designed on whisky-glass side walls and bottom as baffle 2 or baffle 3. The baffle on whisky-glass side walls and bottom helps in mixing of liquid and also act to minimize turbulence within the container and thereby minimize spillage when the container is swirled for mixing of whisky blend.

BACK GROUND OF THE INVENTION:

The traditional and conventional whisky glass is available in different shapes and sizes. However at the time of drinking, when the ice is added in the drink it needs continuous stirring. To get uniform blend, the drink needs to be stirred continuously and for that external stirrer is required.

Presently, when a drink is served, they have to be provided a stirrer and/or they demand the stirrer to mix the drink for universal taste or blend. These external stirrers are difficult to handle as being left in glass, it distorts the pleasure of drink and if kept in plates distorts the snacks and/or other eatables.

Available prior arts (US 2142811 A, US 2428056 A, US 3360160 A , US 4768674 AUS 5370258 A) (To be described after receiving specification of baffle and experiment details)

However, in practice, none of these prior art devices effectively accomplished all of the ultimate desiderata for such a device because they did not completely useful for stirring and mixing of beverage when it is served without any external stirrer and also it does not eliminate the lateral slosh and spillage during stirring or mixing of the beverage in dinking glass, they were relatively expensive to make, unhygienic, unable to use reputedly difficult to clean and they were not usable in containers having other than a fixed diameter. It is to more efficiently overcome these problems and to attain the totality of the aforestated desiderata that the present invention is directed.

Beholding the above points, the inventor has worked on the subject to derive a whisky-glass that has inbuilt capability in such a way that, no external/additional stirrer is required. The new whisky-glass designed in such a way that there would be no requirement of any external/additional stirrers and eventually, one can enjoy the drink with extended pleasure with uniform blend without slosh and spillage during stirring or mixing or dirnk.

OBJECT OF THE INVENTION:

The main object of the present invention it to provide a whisky-glass which eliminates or overcome one or more problems of the prior art.

Another object of the present invention is to provide a whisky-glass which eliminates the requirement of additional or external stirrer.

Yet another object of the present invention is to provide a whisky-glasswhich provides the uniform taste/blend of the drink due to uniform mixing of the drink and ice or any other ingredients.

Further objects of the present invention will be more apparent from the following description which is not intended to limit the scope of the present invention in any way.

SUMMARY OF THE INVENTION:

The inventors of the present invention has surprisingly found that the need of external stirred can be avoided by providing a whisky-glasswhich has baffles designed in such a way to provide the stirring effect at sidewall of the container.

The main aspect of the present invention is to provide a whisky-glasscomprising at least one sidewall defining inner and outer surfaces, a top rim, and bottom end; and one or more baffles are provided in sidewall at specific angle to provide uniform mixing without any additional stirrer.

As per the present invention, the baffles provided in sidewall are with specific angle and specific size which can provide uniform stirring and mixing effect to provide the uniform blend.

DEATILED DESCRIPTION OF THE INVENTION:

The present invention contemplates to a whisky-glass which overcomes the drawback of traditional/conventional drinking means and prides a new design in such a way that the new drinking container or whisky-glassholds the capacity of stirring the held contents without use of any external/additional stirrer.

At present, the drinking container or whisky-glass are designed in such a way that, the drink lovers have to use external/additional stirrers to achieve the uniform taste/blend of the drink and thereafter, they have to leave the stirrer in the glass or to be kept in plate.

If the stirrer is left in the glass, same becomes hurdle for them to drink distorting the pleasure of drink. Even if the stirrer is kept in the plate, the snack in the plate becomes clumsy due the wet effect on the stirrers making the taste un-pleasurable.

With the new design, one or more baffles on the side wall of whisky-glass help the stirring in a scientific manner. When the glass is rotated by the user, the liquid in the glass begins its circular motion. In the path of the liquid, the baffle turns as an obstruction/path guider and with the new guided path, distorting the centrifugal force, the liquid is pushed into the centre forcing it into the non-uniform contents. Within few rotation, the contents of the container or glass turns into uniform taste/blend. This way with the general habit of drink lovers to rotate the glass, the contents present in the glass mixes together without using any external/additional stirrers making their drink more pleasurable. Also, the lowering of the drink and melting of the ice within the contents will also keep the taste/blend uniform for the balance left over.

The examples and embodiments as disclosed and described herein and the various aspects and advantageous details thereof are explained with reference to the non-limiting examples in the following description. Descriptions of generally known components and processing techniques are intentionally not inserted herein so as to not unnecessarily obscure the embodiments herein. The examples and embodiments used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.

The term “whisky-glass” as used herein can be defined as any container which holds the liquid while drinking. The drink can be any beverages for drinking and may include alcoholic as well as non alcoholic beverages.

The term “borosilicate glass” as used herein can be defined s a type of glass with the main glass-forming constituents silica and boron trioxide. Borosilicate glasses are known for having very low coefficients of thermal expansion (~3 × 2-6 /°C at 1°C), making them resistant to thermal shock, more so than any other common glass. Such glass is less subject to thermal stress and is commonly used for the construction of reagent bottles. The common type of borosilicate glass has a very low thermal expansion coefficient (3.3 x 2-6/K), about one-third that of ordinary soda-lime glass. This reduces material stresses caused by temperature gradients which makes borosilicate a more suitable type of glass for certain applications. While more resistant to thermal shock than other types of glass, borosilicate glass can still crack or shatter when subjected to rapid or uneven temperature variations. When broken, borosilicate glass tends to crack into large pieces rather than shattering (it will snap rather than splinter).

Borosilicate glass combines high heat resistance with high stability against chemical aggressions. The long-term service temperature is around 450°C. Furthermore, the glass is resistant to water, neutral and acid solutions, strong acids and saline solutions as well as to chlorine, bromine, iodine and organic substances. These characteristics allow the application where soda-lime glass fails.

This invention relates to means for disturbing the flow of a liquid in a whisky-glass wherein the liquid rotates about a vertical axis, forming a so-called forced vortex. The free surface of the liquid becomes curved according to the centripetal acceleration, the inertia and the pressure within the fluid.

On stirring the liquid in whisky-glass in general produces not only a turbulent motion of the liquid contents of the whisky-glass, but also a rotation of liquid about the axis of the whisky-glass or about the central axis of the whisky-glass. As a result the surface of the liquid becomes curved, i.e. it sinks in the middle and rises at the edge, thus forming a vortex.

The term “baffle” according to this invention comprises stationary parts designed on whisky-glass 1 side wall and bottom as baffle 2 or baffle 3. The object of baffles in whisky-glass is the suppression of these vortices formed by centrifugal force.

The whisky-glass can be selected from the group consisting of tumbler, cup, whisky glass, mug and goblet.

The present invention relates generally to uniform mixing, spill-proof whisky-glassand more particularly to a novel and unique baffle 2 into a serving whisky-glass 1for uniform mixing and to reduce spillage arising from wave action created by motion of the liquid disposed within whisky-glass 1.

As shown in FIGS. 1-3, baffle2 comprises a substantially vertical and/or angular imposed on wall of the whisky-glass which has a columnar shape with either a cylindrical or polygonal having a preselected cross-sectional diameter. Baffles areimposed on the wall and/or bottom of the whisky-glass1, bottom baffles 3 is disposed in substantiallycentred coaxial relationship with the vertical central axis of whisky-glass1.

Baffle 2 comprises a plurality of substantially vertical and/or angular assemblies which are imposed on the side wall of the whisky-glass extend radiallyinwardly from central bottom baffles3of whisky-glass1. Baffles assemblies 2 and 3 frictionally engage on surface and contact therewith to superimposed baffle 2 in relationship to bottom surface 4 of whisky-glass1. Thus, baffle 2contacts with whisky-glass1 to define a reservoir 5 therebetween beneath the sub-regions 6 defined by baffle device 2 as will be hereinafter described. Reservoir 5permits circulation of the liquid disposed within whisky-glass1 under all sub-regions 6 so that when whisky-glass1 is tilted in the well-known or natural manner for drinking to the "last drop", all of the liquid will flow through reservoir 5 and into the particular sub-region through which the drinking person has chosen to drink. Tilting whisky-glass1 in this way causes this particular sub-region to be situated below the others so gravity will cause the flow pattern herein described for emptying whisky-glass1.

Further, the vertical and/or angular height of baffle 2 is predetermined such that the horizontal plane defined by the top of baffle2 is substantially co-planer with the horizontal plane of whisky-glass1. Thus, baffle 2 may be made in various heights for use in whisky-glass having different depths. The height of the vertical and/or angular baffle shall be minimum 5mm depending on the diameter of the whisky-glass. Vertical height of vertical and/or angular baffle is 1/6 or 1/5 or 1/4 part of the diameter of the whisky-glass.

Central baffle3 may, in cross-section be circular thereby defining a cylinder, or, alternatively as shown, may be an n-sided polygon such as the hexagon shown when n=3. As shown in FIGS. 3, n may be equal to the number of baffle 2, such that each baffle2may be attached at each of the n conjunctions or angles of the adjacent sections or sides of the baffle. Whether shaped cylindrically or polygonally, the preferred embodiment defines a central baffle3 with each baffle 2extending radially outwardly therefrom in substantially equi-spaced relationship between each of the adjacent baffle 2.

As most clearly shown in FIGS. 1, 2 and 3, each central baffle 3 comprises flange, which extends from centre to an outer edge 7, and a flange portion. Preferably, each flange portion is a volume marker. Each flange portion extends circularly from the substantially vertical plane of body portion 9 to provide frictional engagement with inner bottom surface 10of whisky-glass 1and baffle 2when liquid is squirreled the whisky-glass therein. Each flange of central baffle 3 is designed to the bottom of whisky-glass to vary the effective radial length of each flange which makes central baffle 3more effective for mixing of liquids. Each flange portion designed vertically from a point adjacent the bottom edge of its associated body portion 9 to a point adjacent the uppermost edge 11of flange to make central baffle 3.

One of the embodiments of the present invention relates to the production of borosilicate whisky glass. Borosilicate glass cylinders with wall thicknesses of about 1mm to 3 mm. or more be drawn in the form of tubes are blown to given shape when the required diameter of the whisky glass and the outer wall surface thereof is to have specific contours such as grooves or flutes, flanges or shields. Optionally centrifugal casting process for producing such whisky glass comprises heating of the borosilicate glass tube of the required diameter of about 3cm to 5cm rotating glass tube for uniform heating and forming it by centrifugal force into a centrifugal casting. The centrifugal casting process is especially desirable for use when whisky glass are to be provided, for example, at the ends or in the interior thereof, reproduced accurately and in quantity.

One of the embodiments of the present invention relates use of borosilicate gall tubes for making baffle on whisky glass. Only borosilicate glass of types of glass cast for baffle on whisky glass. In fact, the choice of glasses is very limited when specific requirements as to the processing temperature or as to coefficients of expansion must be imposed, as is the case, for example, with baffle on whisky glass. It has, moreover, been found that a specific glass which is suitable for casting may be suited for producing an article of any desired shape and, especially, of any desired diameter. Thus, for example, a borosilicate glass, requiring a high casting temperature and suited for producing whisky glass. It is not possible to produced baffle on the non-borosilicate glass or normal glass or soda lime glass and therefore manufacturing of baffle on whisky glass with normal glass or soda lime glass or any other glass is not possible. The cast from glass other than borosilicate glass are subjected to highly erratic and non-uniform internal stresses, notwithstanding the exercise of most painstaking cooling procedures, and scale-like cracks and fissures are consequently formed therein. The causes thereof are not attributable to failings in manufacturing techniques but rather to the structure of the glass being used, i.e., primarily to the temperature and its molten and/or semi solid states thereof.

The invention is directed to a method, herein called “baffle pressing,” for forming thin precise glass articles. On one embodiment the articles formed using the method of the invention have a thickness of less than 5 mm. In another embodiment the thickness of the articles is less than 2 mm. In a further embodiment the thickness of the articles is less than 1 mm.

In one embodiment the invention is directed to a method for forming baffle on side wall of whisky glass, said method comprising the steps of:
heating borosilicate glass tube at above 600°C and making it molten and/or semi solid;
blowing the glass tube to give the particular shape or whisky glass;
baffle pressing on side wall of the whisky glass, pressing the glass until the side walls are sufficiently bent and thereby form a baffle;
optionally cooling the glass; and
removing the whisky glass from the plunger

A further object of the invention is to facilitate the process of making baffle on the whisky glass. These objects are attained in accordance with the general aspects of this invention by mounting / pressing the baffleon borosilicate glass tube members in coaxial relation. There are multiple baffles on the side wall of the whisky glass, preferably three baffles are mounted / pressed at an angel of 11° each.

In a specific and illustrative embodiment of the invention, the mounting / pressing baffle on borosilicate glass tube wall or bottom may have substantially the same thermal coefficients so that a strain-free seal is readily formed at the bottom of the glass. These central baffles3are mounted / pressed in align accurately side wall baffle 2. The centering feature may be readily obtained automatically by casting the central baffles 3 in a precision die to provide a guide ridge in the ring which forms a seat for the metal member. When the ring is fused by suitable heating, the rings form the shape of the central baffle 3.

From the foregoing, it is readily apparent that a useful embodiment of the present invention has been herein described and illustrated which fulfills all of the afore-stated objectives in a remarkably unexpected fashion. It is of course understood that such modifications, alterations and adaptations as may readily occur to the artisan confronted with this invention are intended within the spirit of this disclosure which is limited only by the scope of the claims appended hereto.
