[0001] A glass can have various shapes, colours and dimensions, due not only to the aesthetic
imagination of the producer but also to the use for which it is designed.
[0002] The glass is a container the shape of which is, conceptually, generated by the rotation
(almost always a circular rotation) about a vertical axis, of a segment of a line
(profile) which moves away from the axis in the top part so as to describe the rim
of the glass.
[0003] Said rotation generates a hollow solid, which can be used as a container for beverages.
[0004] The bottom part of the container is closed and has a horizontal resting surface,
to which, up to now, the axis of the container has always been perpendicular.
[0005] Commonly, the resting surface can be obtained by bestowing a plane shape on the bottom
part of the container, or else by adding a base thereto, with the interposition of
a stem.
[0006] For reasons of stability, it is desirable for the centroid of the wineglass filled
with liquid to project into the centre of the base or, at least, to fall always within
the boundary of said base.
[0007] The top part of the container is open, and its rim (forming the mouth) normally lies
in a horizontal plane, parallel to the resting surface and perpendicular to the axis
of the container.
[0008] It is desirable, above all for wines such as champagne and dry sparkling wine to
be drunk using wineglasses made of non-coloured crystal, where a slender and elongated
wine-containing part is separated from its resting base by a long stem.
[0009] Such a glass is referred to as "flute", which comes from the French "flûte", a type
of tall slender glass for champagne and similar drinks that to some extent resembles
a flute on account of its elongated cylindrical shape.
[0010] In the flute, the small diameter of the container is justified both by the fact that
it must limit the capacity of the container itself, given that the wines for which
it is designed must be served in small amounts, and by the fact that it must limit
the surface of exchange between the liquid and the air, thus limiting dispersion of
the characteristic and precious bubbles ("perlage") due to the natural fermentation
of this type of wine.
[0011] The elongated shape bestows on the glass a volume sufficient to limit the formation
of froth, which, at the moment of pouring of the wine is formed in large amounts although,
to limit its formation, the wine is made to slip delicately along the side wall of
the glass, by keeping the glass tilted to form with the axis of the bottle an obtuse,
almost flat, angle (the development of froth means, in fact, a loss in "perlage").
[0012] The stem enables the glass to be lifted up without any need to touch the wine-containing
part, both to allow the drinker to admire more fully the colour and the fineness of
the "perlage" of the contents and in order not to warm up with the heat of the finger
tips the small portion of wine, which ought to be drunk after being kept in the melting
ice at the temperature of 7-8°C.
[0013] Originally, the flute had, instead of its present and usual resting base, a spherical
end, for the purpose of preventing the glass from being put down before it had been
rapidly emptied of its already limited contents; this was so that the wine could be
appreciated in optimal conditions, without it being impoverished in its "perlage"
and warmed up by a longer permanence in the glass.
[0014] To empty the glass, it is necessary to tilt it until every point of the container
is above the horizontal plane passing through the mouth of the person drinking, with
which the edge of the glass is in contact.
[0015] The above operation is easier in cup-shaped or bowl-shaped glasses (where, in order
for the glass to be emptied, the inclination of the generatrix of the cup of bowl
with respect to the axis of the glass is subtracted from the angle of inclination
of the glass) rather than in cylindrical glasses (where, since the generatrix is parallel
to the axis of the container, the angle of subtraction becomes zero). It is easier
with glasses with a wide mouth than with ones with a narrow mouth.
[0016] Belonging to this latter type of glasses is the flute, even though it is not the
only one, where the inclination of the glass is also limited by the contact of its
rim with the nose of the person drinking, who, in order to impart upon the glass the
necessary inclination, is forced to incline his head backwards.
[0017] The main purpose of the invention is to eliminate the drawbacks referred to above,
thus providing a solution to the operation of emptying of said type of glasses, without
requiring any need for the user to incline his head backwards, with an action that
is uncomfortable and unaesthetic.
[0018] The invention, as is characterized by the claims, consists in a glass where its rim
(forming the mouth) lies in a plane inclined with respect to the axis of the wine-containing
part (container).
[0019] The mouth of the container, if the latter is cylindrical, will no longer be circular
but elliptical, and the user will rest his lips on the rim of the container in the
one of the two points with horizontal tangent that is set at the higher level from
the base of the glass.
[0020] The elliptical shape of the rim will enable, in the vertical plane which contains
the major axis of the ellipse, a greater degree of inclination of the glass, before
the latter comes into contact with its user's nose.
[0021] Furthermore, the fact that the edge of the glass has an elliptical shape, with the
major axis oriented, at the moment of use, as the projection of the user's nose, not
only enables the aforementioned greater inclination of the glass before this will
come into contact with the nose but also enables the bouquet of the wine to reach
the nostrils limiting its dispersion at the sides of the nose, where the ellipse has
its minor axis.
[0022] Even though the cylindrical shape of the container is the most usual one, it is described
hereinafter merely as an example of embodiment of the invention. The container may
have any other shape in so far as the inclination of the plane of the mouth with respect
the axis of the container bestows on the glass the same improved characteristics as
those described for a cylindrical container.
[0023] The glass thus devised may be made with a base perpendicular to the axis of the wine-containing
part, or else it may be possible to recover the parallelism between the plane of the
mouth of the glass and its resting surface by means of appropriate and suitable inclination
or conformation of the stem that joins the base to the wine-containing part.
[0024] Both of the above embodiments enable the user, by appropriately holding the glass,
to keep the wine-containing part in a vertical position in order to limit the surface
of contact between the air and the contents.
[0025] The second embodiment moreover enables the wine to be poured correctly even with
the glass in the resting position by causing it even so to run down the internal surface
of the glass, which presents with the wine-containing part already inclined with respect
to the horizontal plane, in this way causing a limited amount of froth to form and
consequent contained dispersion of "perlage".
[0026] The practice of pouring champagne and sparkling wines into flûtes which are inappropriately
resting on a surface is a custom that is as widespread as it is to be deprecated in
so far as, by so doing, the wine falls from the bottle for the entire height of the
glass and directly impinges upon the wine that has preceded it during pouring, thus
mixing therewith, with the consequent formation of a very high amount of froth and
a proportional loss of "perlage".
[0027] Other characteristics will emerge more clearly from the ensuing description with
reference to the attached plate of drawings, in which:
Figure 1 is a side view of the glass;
Figure 2 is a front view of the glass;
Figure 3 is a top plan view of the glass;
Figure 4 is a side view of the glass provided with a container for the ice;
Figure 5 is a front view of the glass illustrated in Figure 4; and
Figure 6 is a top plan view of the glass illustrated in Figure 4;
Figures 7-9 show the glass of Figures 1-3 with a difference in the shape of the mouth;
and
Figures 10-12 show the glass of Figures 4-6 with a difference in the shape of the
mouth.
[0028] With reference to Figures 1, 2, and 3, the glass forming the subject of the invention,
which may be made of any material, preferably variously coloured glass and/or crystal,
comprises a resting base 2, from which there departs, in a direction either perpendicular
to the base or not, a stem 3 having an axis which is inclined or perpendicular with
respect to the base, at the top end of which the wine-containing part 4 is located,
having an inclined axis, with the plane 5 of its mouth 6 parallel or otherwise to
the base 2.
[0029] As has been said above, the glass forming the subject of the present invention may
be made even with the axis of the stem 3 perpendicular to the base 2. The axis of
the wine-containing part 4 will always be inclined, and the plane 5 of the mouth 6
may be parallel or not to the base 2.
[0030] Of course, in all the solutions, for reasons of stability the centroid of the glass
full of liquid must fall in any case within the boundary of its resting base.
[0031] In the solution described herein merely by way of example, there has been chosen
the cylindrical shape of the container in so far as it is the most usual one, but
any other shape may be used. In this case, the mouth 6 of the cylindrical container
will no longer be circular but will have an elliptical shape 7, and the lips of the
user will rest on the rim 8 of the container in the one of the two points with a horizontal
tangent that is at a higher level from the base 2 of the glass.
[0032] The aforesaid elliptical shape 7 of the rim 5 will enable, in the vertical plane
that contains the major axis of the ellipse, a larger degree of inclination of the
glass 1 before this comes into contact with the nose of its user, thus preventing
the need for the user to incline his head backwards.
[0033] In addition, the aforesaid elliptical shape 7 of the rim 5 with the major axis oriented
at the moment of use as the protrusion of the nose of the person drinking also enables
the bouquet of the wine to reach the drinker's nostrils, thus limiting dispersion
of the bouquet at the sides of the nose, where the ellipse 7 has the minor axis.
[0034] Represented in Figures 4, 5, and 6 is a variant embodiment of the invention, which
consists in the fact that the glass 1 comprises a compartment 9 for housing melting
ice-cubes having the purpose of maintaining the portion of wine contained in the wine-containing
part 4 at a temperature of between 7 and 8°C, thus preventing any watering-down of
the contents deriving from the fact that the ice-cubes are inserted directly in the
wine-containing part.
[0035] The glass of Figures 7-9 and 10-12 show a small difference respectively in reference
to the glass shown in Figures 1-3 and 4-6; the difference consists in the shape of
the mouth 6 that, however, maintains its elliptical shape 7 according to the invention.
[0036] The invention described above solves the problem of providing a wineglass contained
in a plane that is in any case inclined with respect to its base and to its drinking
plane, which lies on a plane parallel or not to the plane of the resting base.
[0037] Of course, the present invention is not limited to the arrangements described and
represented herein, but rather may undergo further improvements and possible variations,
particularly if these are dictated by requirements of practical use.
