Description
BACKGROUND
[0001] Drinking glasses have been in existence for many years.
Various shapes of drinking glasses have been used for specific
types of beverages. Water, sodas, milk and juice are typically
poured into glasses that typically have a flat base and cylindrical
body that maximizes the volume of liquid that can be contained. The
cross section of the glass is typically circular but may be any
other geometric shape. The sidewalls may be straight or curved. In
contrast, a wine glass has a very different shape because it is
used to drink and taste wine. The wine glass has a smaller volume
than a drinking glass. The base is a circular disk that is coupled
to the rounded cup with a thin stem. The shape of the cup is
designed to concentrate the aroma or bouquet of the wine making it
easier to distinguish the varietals' characteristics. The wine
glass is typically made from blown glass.
[0002] Many glasses are designed for specific types of wines.
Glasses for red wine are characterized by their rounder, wider cup,
which gives the wine a chance the breath. Bordeaux glasses are tall
with a wide cup for full-bodied red wines such as Cabernet and
Merlot. Burgundy glasses are larger than Bordeaux glasses with a
larger bowl for more delicate wines such as Pinot Noir. White wine
glasses are narrower than red wine glasses and champagne flutes are
narrower than white wine glasses. White wines and champagnes are
intended to be served chilled, and these narrower glasses help to
retain the cooler temperature. There are other glasses having
shapes for port, sparkling wine, brandy, liqueur, cocktail and
water.
[0003] A problem with both drinking and wine glasses is that they
are typically bought in sets that look identical. While this
identical appearance is aesthetically pleasing, it is very easy to
set a drinking glass down and not be able to distinguish one glass
from another. With plastic cups, a marker can be used to write the
user's name on the outer surface. However, most people would prefer
to drink from a glass cup.
[0004] A device used for identifying wine glasses is a stem tag
that is secured to the stem of each glass. Each glass is marked
with a different tag, and each tag has a distinct pattern. A user
can identify his or her glass by remembering the appearance of the
stem tag. While the wine glass tags are useful, they must be
removed before the glasses are washed and are easily lost once they
are removed from the glasses. A problem with these tags is that
they can be fragile and difficult to secure around the stems of the
wine glasses.
SUMMARY OF THE INVENTION
[0005] The inventive drinking cup marking system includes a cup
that has an integrated magnet and a magnetic marker. The user
attaches the magnetic marker to the cup while it is being used so
that the cup can easily identified. The markers may be
informational as well as ornamental. After use, the magnetic
markers can be removed so that the glasses can be washed.
[0006] The magnets may be attached to any part of the glasses. For
normal drinking glasses, the magnets may be mounted anywhere close
to the outer surface but may be at least an inch below the rim to
avoid potential contact with the user's mouth. For wine glasses,
the magnets may be mounted on the cup portion, the base or the
stem.
[0007] The user may select the marker(s) based upon the use of the
inventive cup. For example, the markers may identify the beverage,
identify the user of the cup, correspond to an interest or a
holiday, etc. The markers may vary in shape, color and pattern. It
is desirable to mount the marker onto the cup and have it stay in
place while in use. In order to avoid accidentally knocking the
markers off of the cup, the markers may be flat structures that
resemble small buttons. As discussed, the markers may have
ornamental or functional markings such as letters or words.
[0008] To further improve the adhesion of the marker to the cup,
indentations may be formed in the cup to secure a portion of the
marker in place. In an embodiment, the marker has a specific shape
and the cup has a corresponding indentation that engages the outer
edges of the marker. For example, if the marker is circular, the
cup may have a corresponding circular indentation. When the marker
is attached to the cup, the edges of the indentation will engage
the outer diameter of the marker to prevent the marker from being
moved across the surface of the cup. Thus, the marker may only be
pulled straight off the cup surface.
[0009] In other embodiments, various other combinations of markers
and cup magnets may be used. In an embodiment, the cup may have a
protrusion that engages a hole or indentation in the marker. In yet
another embodiment, the indentation or protrusion may correspond to
a non-circular feature that prevents the rotation of the marker.
For example, the cup may have a rectangular indentation that
engages the edges of a rectangular marker. The outer surface of the
marker may be flush with the outer surface of the cup or protrude
slightly.
[0010] To further improve the adhesion of the marker to the cup,
the magnetic markers may have a surface that corresponds to the
mounting surface on the glass. A marker may have a curved surface
that corresponds to the curvature of the glass. The radius of
curvature may correspond to the cup feature. A marker that is used
with a magnet in the stem of a wine glass will have a smaller
radius curvature than a marker that is attached to the base or cup
portions of the glass.
[0011] In an embodiment, the magnets used with the system are
Ceramic (ferrite) magnets that are composed of strontium carbonate
and iron oxide. If magnets are used in both the cup and marker, the
polarity orientation of the magnets must be properly aligned.
Magnets have a negative pole and a positive pole, and each pole is
attracted to the opposite pole of other magnets. Thus, if the
negative pole of the cup magnet faces out, the marker magnet should
be oriented with the positive pole facing in.
[0012] Although the system has been described as a magnet in the
cup and a magnetic marker, it is also possible to use metals that
are magnetically attracted such as steel or iron, nickel, cobalt
and other ferromagnetic materials. Thus, the present invention will
be functional if the glass has a piece of steel and the marker has
a magnet. The inventive system will also work if a magnet may be
attached to the glass and the marker has a magnetic metal.
[0013] The magnets attached to the cup may be small ceramic magnets
or iron oxide magnets. In other embodiments, the magnets may be a
fine iron oxide powder that is mixed with the glass used to make
the cup. This mixture creates a translucent magnetic surface.
Because beverage containers are typically made of a transparent or
translucent material, the powdered magnetic material is less
apparent to the eye.
[0014] There are various ways to attach the magnets to the drinking
glasses. In an embodiment, the magnets may be simply attached to a
surface of the container. The attachment mechanism may be an
adhesive or the cup material may be partially melted to bond the
magnet. To help retain the magnet, a bore or a through hole may be
formed in the cup and the magnet may be bonded within the bore or
through hole. The magnet may be mounted flush with the outer
surface of the cup or it may be mounted below the surface. If the
magnet is mounted below the surface, the marker magnet may also fit
within the bore so that edges of the marker may fit within the hole
to prevent accidental removal.
[0015] The base has a lower planar surface that allows the glass to
sit upright when placed on a planar surface. The base is typically
a circular member that has a lower fitting. The upper and lower
fitting engages a rod that functions as the stem of the drinking
glass. In an embodiment, the magnets may be mounted in the stem or
base. These areas may be preferable because they are away from the
beverage-containing portion of the drinking glass.
[0016] The markers can be ornamental and have a variety of shapes,
patterns, colors and finishes. The markers may also be
informational and have a plurality of alpha-numeric characters.
Multiple magnets may be attached to the cup so that multiple
markers can be placed on the cup. The markers are interchangeable
which allows the user to create glasses that are distinct and
individually identifiable. Each of the glasses may have a marker
indicating the person using the glass. It is also possible for
users to create temporary monogram lettering for the guests.
Alternatively, the markers may be color coded to indicate the guest
or the type of beverage served in the glass. The inventive drinking
glass may be sold in a gift box and may include one or more
beverage glasses and a set of markers. Additional markers can be
purchased that have different designs so that the glasses can be
used for different occasions.

DETAILED DESCRIPTION
[0023] With reference to FIG. 1, the present invention is a wine
glass that has a cup 103, stem 107 and base 111. The upper portion
of the cup 103 has a circular opening with a thin rounded lip and a
thin wall section. The top of the stem 107 is attached to the
bottom of the cup 103, and the bottom of the stem is attached to
the base 111. The base 111 is a circular structure. The cup 103,
stem 107 and base 111 are preferably made of clear glass. Although
the drinking glasses are described as being made of glass, in other
embodiments the drinking glasses may be made of metal, ceramic,
plastic, wood or composite materials.
[0024] The glass illustrated in FIG. 1 also includes a plurality of
magnets 131 that indicates some of the possible locations for the
magnets. In an embodiment, the magnets 131 may be located around
the perimeter of the cup 103. The magnets 131 may also be located
in the stem 107 and base 111. The magnets 131 in the stem may be
cylindrical while the magnets 131 in the cup and base may be more
planar in design. In an embodiment, the magnets 131 in the cup 103
are located on the outer surface of the cup 103, partially embedded
in the cup 103 or fully embedded in the cup 103.
[0025] Various types of permanent magnets or magnetic materials may
be attached to the cup and used to attach the markers. The
permanent magnetic materials include rare earth magnets, ceramic
magnets and alnico magnets. Rare earth magnets include:
neodymium-iron-boron and samarium-cobalt. Ceramic magnets are
typically made of a ceramic material that includes magnetic iron
oxides. Plastic magnets are made of a non-metallic polymer which is
a combination of polyaniline and tetracyanoquinodimethane.
[0026] Alnico magnets are made by casting or a combination of
aluminum, nickel and cobalt with iron and small amounts of other
elements added to enhance the properties of the magnet. Sintering
offers superior mechanical characteristics, whereas casting
delivers higher magnetic fields and allows for the design of
intricate shapes that may allow for easier attachment to the cup.
Alnico magnets also resist corrosion and have physical properties
more forgiving than ferrite.
[0027] In an embodiment, a magnetic material in a powdered form may
be mixed with polymer resins so that they can be injection molded
into any desired shape or into the cup itself. The injection
molding process involves injecting the magnetic material in the
resin into a mold and letting the resin harden into the shape of
the mold. The finished produce will be magnetic and have the
physical properties of a plastic material. In an alternative
embodiment, the magnetic materials may be mixed with glass that is
then formed into a drinking cup.
[0028] Flexible magnets may also be formed that are similar to
injection molded magnets, using a flexible resin or binder such as
vinyl, and produced in flat strips or sheets. These magnets are
very flexible and therefore may be more easily attached to the cup.
Because the cups are generally made of a very thin material, it may
be desirable to have very thin magnetic materials attached to the
cups. In the preferred embodiment, the magnets or magnetic
materials attached to the cup should be less than 1/4 inch
thick.
[0029] In yet another embodiment, an electromagnet may be attached
to the cup which includes wires wrapped in a coil and battery to
supply current. The battery may be a conventional battery,
rechargable battery or even a solar cell that is able to convert
ambient light into electricity.
[0030] In other embodiments a magnetic material, rather than a
permanent magnet, is attached to the cup. The material is not
normally magnetic but is attracted to permanent magnets. In this
embodiment, the marker has a magnet that is attracted to the
magnetic material attached to the cup. The magnetic material may be
a metal that contains iron, steel or any other material that is
magnetically attracted to a magnetic field.
[0031] The magnets 131 may be attached to an outer surface of the
glass with an adhesive such as epoxies, thermoplastics,
pressure-sensitive adhesives, chemical bonding polymers or other
glass adhesives. The magnets 131 may also be covered with a
protective material that isolates the material from water or other
beverage. Because many magnets include iron oxide, there is a
tendency for the magnets to rust. The potential rust issue maybe
prevented by applying a protective coating so that the water cannot
contact the iron oxide.
[0032] Alternatively, the magnets 131 may be embedded within the
cup material. More specifically, the magnets may be inserted into
the glass as the cup is being made. If the magnets 131 are
embedded, the cup materials will cover the magnets 131 and prevent
contact with water and rust. In an embodiment, the magnets attached
to the cup may be an iron oxide powder. In this embodiment, the
magnetic powder may be mixed with the glass or plastic used to make
the cup or a layer of the cup so that the finished cup is magnetic.
Because the magnetic powder is very fine the resulting cup may be
translucent.
[0033] In the preferred embodiment, the markers are small flat
ornamental pieces that are attached to magnets or magnetic
materials. The marker may have two sides--a magnetic side, which
has the magnetic material, and the outer ornamental side. The
magnetic side of the marker may include any of the magnetic
materials described above. Because the markers are typically being
attached to convex surfaces, the magnetic side may be concave so
that the outer edges of the marker contact the cup. For example, if
the markers are being used with a cylindrical cup, the inner
surface may have a cylindrical concave surface that is similar in
shape. If the marker is used on the cup portion of a wine glass,
the magnetic surface may be a spherical concave surface to match
the outer cup surface.
[0034] The outer portion of the marker may be ornamental. An
infinite number of designs and finishes are possible. In an
embodiment, the ornamental sides of the markers may resemble a
colored circular bead. Each glass may be marked with a different
colored bead so that each can be distinguished. In other
embodiments, the markers may have different shapes such as squares,
rectangles, triangles, ovals, etc. The markers are preferably flat
so that they are less likely to be knocked off of the glass;
however, they may also have three-dimensional shapes such as domes,
pyramids, cubes, etc., that protrude away from the surface of the
glass.
[0035] In addition to different colors, the markers have specific
patterns, letters or numerals. The markings can be printed or
permanently formed in the surface of the bead. For example, the
markers may be embossed or the markings may be protrusions formed
on the bead surface. The letters can be used to create monogram
drinking glasses for each of the users. Similarly, the markers can
be numbered or have a combination of numbers and letters.
[0036] The appearance of the markers can be purely ornamental or
used for identification of the glass. The ability to identify a
wine glass is particularly useful during parties with a number of
guests. Each guest may be given a glass with a specific markers
that indicates the guest's name or initials. Because the glass has
a specific marker, the guest will be able to set the glass down and
then identify the glass from all other glasses.
[0037] The color and shape of the markers may also allow for visual
identification for a wine tasting party. While wine glasses with
the same cup portion may be used to serve both Cabernets and
Merlots, the marker text or pattern may allow guests to distinguish
the Cabernets and Merlots. The markers may also allow guests to
distinguish various brands of a specific type of wine or to
distinguish different varietals for tasting comparison
purposes.
[0038] The interchangeably of the markers with regard to the color,
shape and material allows for an infinite combination of
appearances. In order to improve the interchangeability of the
markers, the size of the magnets may be uniform. For example, the
magnet may be a 1/4 inch diameter circle that is 1/8 inch thick and
the marker may also have a 1/4 inch diameter magnet. The attraction
force of the marker to the magnet is related to the distance
between the magnets. The marker will be highly attracted to the
surface of the magnet while there will be less of a magnetic force
if the marker is separated from the magnet. For the best magnetic
adhesion, the marker magnet and the drinking glass magnet should be
in close proximity and may be the same size. A strong magnetic
force will keep the marker in a specific location. If the magnet in
the glass and the marker magnet are different sizes, the magnetic
fields are not aligned and the placement of the marker is less
precise.
[0039] The force produced between two magnets may be defined by the
formula:
F=(.mu.)(m.sub.1)(m.sub.2)/4.pi.r.sup.2
[0040] Where F is the attractive force, m.sub.1 is the pole
strength of the first magnet, m.sub.2 is the pole strength of the
second magnet, .mu. is the permeability of the intervening medium
(glass or air) and r is the separation of the magnets.
[0041] The magnets may be attached to the cup, stem or base of the
beverage container. In an embodiment, the magnets are embedded into
the partially melted glass or plastic. Alternatively, the magnet is
placed under the base. If the base is opaque, the magnet will not
be visible. In an embodiment, the magnets may be used to create a
design around an outer diameter of the drinking glass. Multiple cup
magnets would allow a plurality of markers to be arranged around a
diameter of the cup portion of the glass or in a ring around the
base.
[0042] It should be noted that certain magnets may contain iron
oxide, which may be prone to rusting when exposed to water or other
liquids. Thus, the magnets should be separated from the liquid
contained in the cup. Further, to avoid rust during washing, the
magnet may be sealed in a waterproof manner. The magnetic particles
may be encased in a plastic material or sealed within the glass or
plastic of the beverage container. The protective layer may be a
transparent or opaque coating of paint or plastic.
[0043] In an embodiment, the magnet is embedded within the cup
material. By inserting the magnets during manufacturing, they may
be fully encased within the glass or plastic. In order for the
magnets to fit into the cup material, thin magnets should be used
and placed in a thick portion of the cup. In another embodiment,
the magnet may be a plurality of small or fine magnetic particles
that are mixed with the cup material. Because the particles are not
a unitary piece, the magnetic particles are less noticeable in a
transparent or translucent cup or glass.
[0044] In an embodiment, the attachment surface of the cup or glass
may have special features that enhance the attachment of the
marker. In an embodiment, the glass has an indentation that matches
a corresponding feature on the marker. By coupling the features of
the glass and marker, the marker is more securely attached to the
glass. With reference to FIG. 2, various possible coupling features
on a glass are illustrated. The front and side views for each
coupling system are shown. The magnet 211 is square in shape and
mounted at the bottom of a square hole 213. A marker that has a
corresponding square shape can be placed at least partially in the
hole 213. Because the sides of the marker engage the sides of the
hole 213, the marker can only be removed by pulling straight away
from the cup 201. The engagement of the features causes the marker
to resist being displaced by side forces that are applied to the
marker.
[0045] Magnet 221 is a circular magnet that protrudes from the
glass 201. A marker placed on the magnet 221 may have a circular
indentation that engages the outer edges of the magnet 221. The
engagement of the outer edge of the magnet 221 and the inner edge
of the marker prevents horizontal movement and helps to keep the
marker in the proper place on the glass 201. Magnet 231 is a
circular magnet mounted at the bottom of a square hole 233 or
indentation. A marker having a square magnetic side that
corresponds to the hole is attached to the glass. Magnet 241 is a
circular magnet at the bottom of a round hole 243 that should be
used with a marker having a corresponding round magnetic side. An
advantage of the square shape of the hole 233 is that it prevents
the marker from rotating. In contrast, the round hole 243 would
allow a marker to rotate.
[0046] Magnet 251 is a circular magnet mounted below a rectangular
hole 253. In this embodiment, the magnet 251 is fully embedded
within the glass material that isolates the magnet from water and
other elements. Thus, the marker may be attracted to the magnet 251
but will not make any contact. The rectangular hole will also
prevent a marker with a corresponding magnet side from rotating.
Magnet 261 is an annular magnet that has a center hole 263. The
marker may have a center pin that fits in the center hole 263 and a
magnet that is attracted to the magnet 261 to hold the marker in
place.
[0047] FIG. 3 illustrates some exemplary markers that are attached
to a glass 300. Magnet 301 is a circular magnet mounted at the
bottom of a circular hole 303. The marker 305 has a corresponding
circular magnet 307 that fits within the hole 303. The marker 305
may have a circular ornamental side 309 that has the letter "M."
Magnet 311 is mounted within the glass 300 to isolate the magnet
311 but does not have any features to hold the marker 315 in place.
The marker 315 has a magnet 317 that is flush with the back of the
marker 315. The ornamental side 319 is marked with the letter "T."
Magnet 321 is mounted within the protective glass 300 and has a
corresponding square hole 333. The marker 335 has a magnet 337 is
also square and fits within the hole 333 but cannot rotate. The
engagement of the magnet 337 and the hole 333 helps to keep the
marker 335 in place. The ornamental side is 339 is square with
rounded edges and is marked with the letter "L."
[0048] Magnet 341 is mounted at the bottom of a square hole 343. A
square marker 345 has a magnet 347 and fits within the hole 343.
The marker 345 may be nearly flush with the outer surface of the
glass 300. The ornamental side of the marker 345 may be curved to
match the outer glass surface and has the letter "M." Magnet 351 is
mounted on the surface of the glass 300. The marker 355 has a
magnet 357 and a recessed hole 353. When the marker 355 is attached
to the glass 300, the magnet 351 fits within the recessed hole 353.
Magnet 361 is also attached to the outer surface of the glass 300.
The marker 365 has a magnet 367. When the marker 365 is attached to
the magnet 361, the marker 365 is attached to the glass 300 but not
in direct contact because the magnet 361 holds it away from the
outer surface.
[0049] With reference to FIG. 4, the glass 401 may have multiple
magnets 405 that are used to secure a single flexible marker 407.
In this embodiment, the marker 407 is a flexible strip that wraps
around a cylindrical portion of the cup 401. Because the marker 407
is fairly large, multiple magnets are needed to secure it to the
glass 401. In an embodiment, the marker 407 is made of a plastic
magnetic material that is flexible. Thus, the entire marker 407
will be attracted to the magnets 405 in the glass 401 and precise
alignment of the marker 407 is not required.
[0050] With reference to FIG. 5a, a wine glass 501 having magnets
511 in the stem 503 is illustrated. In this embodiment, a marker
515 has a magnet 517 and an inner curvature that is designed to fit
partially around the stem 503. The upper marker 515 shows a front
view and the lower marker 515 shows a side view in which the sides
of the marker wrap partially around the stem 503. FIG. 5b
illustrates a top view cross section of the marker 515 and shows
the inner curvature 519 that corresponds to the outer diameter of
the stem 503. In an embodiment, the inner curvature of the marker
515 may be slightly smaller than the stem 503 diameter so that the
marker holds the stem 503 tightly. The magnetic attraction holds
the marker 515 against the stem 503 and prevents the marker from
sliding up and down the stem 503.
[0051] In other embodiments, the stem 503 and marker 515 may have
features that engage each other to resist movement of the marker
515. For example, the stem 503 may have edges that engage the upper
and lower ends of the marker 515 and prevent it from sliding on the
stem 503. In another embodiment, two or more markers may be
attached around the magnet 517 of the stem 503. If two markers are
used, they may each surround one half of the stem and may also be
coupled to each other.
[0052] After the markers are used with the glasses, they should be
removed before the glasses are cleaned and stored. The user can
simply pull the markers away from the glasses and store the markers
together. The ability to remove easily the marker from each glass
allows for easy cleaning. With the markers removed, the glasses can
be washed without the fear of loosing the markers down the sink
drain or getting caught in the dish washer cleaning mechanisms.
[0053] In the foregoing, an interchangeable system of beads used as
the stem of a drinking glass or the handle of an object has been
described. Although the present invention has been described with
reference to specific exemplary embodiments, it will be evident
that various modifications and changes may be made to these
embodiments without departing from the broader spirit and scope of
the invention as set forth in the claims. Accordingly, the
specification and drawings are to be regarded in an illustrative
rather than a restrictive sense.
