Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation-in-part of co-pending
application Ser. No. 10/790,954, filed Mar. 1, 2004.
FIELD
[0002] Beverage lid plugs
BACKGROUND
[0003] Beverages, particularly transportable and/or disposable hot
beverages (e.g., coffee, tea, hot chocolate, etc.), are generally
packaged in cups having a detachable lid (e.g., a plastic lid). The
cups generally come in a variety of sizes (small (eight to 10
ounces (oz.)), medium (12 oz.) and large (16 oz. or greater). Thus,
lids also come in a variety of sizes and each lid has its own shape
and sized opening from which a person may consume the beverage.
[0004] Typically, a transportable and/or disposable beverage
container is a paper or foamed polymer cup having a generally
conical shape. Rigid or hard polymer materials are also used as
transportable beverage containers that are generally intended to be
reusable. A typical lid is generally a hard plastic material having
a base including a radius suitable to surround and fit snugly on a
lip of the container. Alternatively, particularly in the case of
rigid polymer material beverage containers, a typical lid may have
a radius to fit within a superior radius of a conical-shaped
container. A typical lid has a superior surface (generally
cylindrical) having an opening through a body of the lid and
through which the contents of the beverage container may be
consumed. Representatively, a consuming opening may have a
generally elliptical (e.g., oval) shape with a major axis on the
order of 0.3 inches to 0.5 inches.
[0005] A superior surface of a lid may also include a second
opening separate from a consuming opening. The second opening is,
for example, suitable to allow air into the beverage container (for
example, while the beverage is being consumed) and may be as small
as a pin hole or similar sized opening. With this in mind, the
second opening is almost always smaller than the consuming opening,
and is usually considerably smaller than the consuming opening.
[0006] Many times while transporting (e.g., walking, driving, etc.)
the cup (container and lid) containing the beverage moves in a
manner which causes its contents to spill through the consuming
opening in the lid. This situation causes consumers a great deal of
discomfort and aggravation.

DETAILED DESCRIPTION
[0024] FIG. 1 shows a bottom view of one embodiment of an apparatus
suitable for blocking (e.g., sealing) an opening in a lid of a
beverage container. FIG. 2 shows a side view of apparatus 100. In
one embodiment, apparatus 100 includes base 110. Base 110 in the
embodiment shown in FIG. 1 and FIG. 2 is an elliptical piece of
material. In other embodiments, base 110 may be any shape (e.g.,
rectangular, including a square, circular, triangular, etc.).
[0025] Base 110, in the embodiment shown in FIG. 1 and FIG. 2, has
a longitudinal length, L, approximately equivalent to a diameter of
a lid of a transportable beverage container. Where a lid is
attached to a lip of a beverage container and a top surface of the
lid defines a top surface of a collective cup (container and lid),
base 110 may have a length greater than or less than a diameter of
a lid. Where a lid fits within a superior radius of a container,
for example, base 110 may have a diameter less than a diameter of a
lid. Representatively, in one embodiment, base 110 has a length on
the order of about two inches. Other embodiments of base 110 have a
length in the range of about one half inch to about four inches. In
addition, base 110 may be shorter than one half inch and longer
than four inches in other embodiments.
[0026] Base 110, in one embodiment has a lateral width, W,
sufficient, at least at one portion, to accommodate a protrusion
having dimensions suitable to fit within a consuming opening of a
lid. A suitable lateral width may be constant or fluctuate along a
longitudinal length, L. Representatively, in one embodiment, base
110 has a lateral width, W, of about one inch. In other
embodiments, base 110 has a width in the range of about one half
inch to about two inches. It is contemplated that base 110 has any
width capable of containing a protrusion sufficient to block (e.g.,
plug) an opening in the lid of a beverage container.
[0027] In one embodiment, base 110 is formed of plastic. Other
suitable materials include, but are not limited to, paper,
cardstock or cardboard. Base 110 has a sufficient rigidity to
render it suitable to be placed on a lid of a beverage container
and to be retained on the lid without an application of an external
force. In one embodiment, a sufficient rigidity is defined, in
part, by a thickness, T, of a material for base 110.
Representatively, a suitable thickness, T, is on the order of 0.25
inches. Other thickness, perhaps much greater than 0.25 inches are
also suitable. Collectively, the dimensions (e.g., 0.0625 inches or
greater) of base 110 are such that, in one embodiment, it is
grippable by a consumer of a beverage container and may be gripped
by, for example, two fingers and placed on or removed from a lid of
a beverage container.
[0028] In one embodiment, apparatus 100 includes protrusion 120
extending from a surface of base 110. Protrusion 120, in one
embodiment has dimensions (e.g., a length, l, and a width, w)
suitable to fit within at least a portion of a consuming opening of
a lid. Representatively, protrusion 120 has a dimension that is
approximately the same as or less than a dimension of a consuming
opening (e.g., a length, l, and a width, w, that is equal to or
less than a length and a width of a consuming opening).
[0029] In one embodiment, protrusion 120 has a thickness, t,
suitable to extend from a surface of apparatus 100 into a consuming
opening of a beverage container lid when apparatus is placed on or
rests on the lid. Protrusion 120 may have a thickness, t,
equivalent to a thickness of a lid or much less (e.g., just enough
to extend into the opening).
[0030] Protrusion 120, in one embodiment, has a thickness, t,
sufficient so that when base 110 lies on a surface of a lid of a
beverage container, protrusion 120 protrudes or extends a distance
from a surface of the lid sufficient to protrude or extend into a
consuming opening in a lid of a beverage container to block (e.g.,
plug) the opening. In one embodiment, a suitable protrusion
distance or thickness, t, is about one eighth inch. In other
embodiments, protrusion 120 has a thickness, t, in the range of
about one sixteenth inch to about one half inch. In addition,
protrusion 120 may be any thickness, t, that is sufficient to
adequately fill an opening in the lid of a beverage container.
[0031] As shown in FIG. 2, protrusion 120 extends, in one
embodiment, in a substantially perpendicular direction with respect
to side 210 of base 110. In other embodiments, protrusion 120 may
form other angles with respect to side 210.
[0032] Protrusion 120, in one embodiment, is formed of a deformable
material. Representatively, if protrusion 120 is larger or has a
different shape than an opening in a lid of a beverage container,
the deformable material is capable of contracting to a size and
shape to allow protrusion 120 to fit snuggly within the opening. In
one embodiment, the deformable material is a sponge material (e.g.,
open cell sponge or closed cell sponge). Other suitable materials
include, but are not limited to, plastic (foamed or non-foamed
polymers, synthetic rubber etc.) or any other material capable of
being compressed and expanding thereafter.
[0033] Protrusion 120, in another embodiment is formed of plastic.
Other materials suitable for forming protrusion 120 include, but
are not limited to, paper, cardstock or cardboard.
[0034] In one embodiment, protrusion 120 is formed of the same
material as base 110. Representatively, base 110 and protrusion 120
are formed in a single mold to form apparatus 100. In another
embodiment, base 110 and protrusion 120 are formed in separate
molds or as otherwise separate structures and connected together
using an adhesion material. In another embodiment, a heat process
is used to melt base 110 to protrusion 120.
[0035] Base 110 and protrusion 120, in one embodiment, are formed
of different materials. For example, base 110 may be formed of
cardboard while protrusion 120 is formed of plastic. Other
embodiments include any combination of the materials discussed
above for base 110 and protrusion 120.
[0036] In addition, apparatus 100 may be any color or combination
of colors. In one embodiment, apparatus 100 is a single color. In
another embodiment, apparatus 100 is multi-colored. In another
embodiment, base 110 is a different color than protrusion 120.
[0037] It is contemplated that protrusion 120 may be oriented any
where on base 110. For example, as shown, protrusion 120 is
oriented toward one side of base 110, however, protrusion 120 may
be oriented in the middle of base 110 or any other place on base
110, including, but not limited to, a top side, a bottom side and a
perimeter side extending laterally as represented by T in FIG.
2.
[0038] Apparatus 100, in one embodiment, includes aperture 130. In
FIG. 1, aperture 130 is formed in base 110. Representatively,
aperture 130 is of a size capable of having an attachment member
(e.g., a key chain) placed through aperture 130. FIG. 3 shows a
bottom view of apparatus 100, including aperture 130. Aperture 130,
in the embodiment shown in FIG. 3, is circular and suitable for
attaching apparatus 100 to another object (e.g., a key ring).
Representatively, aperture 130 may be circular with a diameter of
about one tenth inch. In other embodiments, aperture 130 has a
diameter of about one sixteenth inch to about 1.75 inches. Aperture
130, in other embodiments, may be any shape, for example,
rectangular, including square, triangular, oval, etc., and may be
any size suitable to attach to another object, but while still
being within the confines of apparatus 100.
[0039] FIG. 4 shows apparatus 100 placed on a lid of a beverage
container, for example, for ease in stacking the lid during storage
and/or shipping. In the embodiment shown in FIG. 4, recessed area
140 at one end of base 110 is shaped to mirror the shape of a rim
of the lid with which apparatus 100 is attached. In another
embodiment, apparatus 100 may be oriented in the opposite direction
such that base 110 would essentially extend over the lid of the
beverage container rather than extending beyond an edge of the
beverage container as shown.
[0040] As shown in FIG. 4, base 110 extends beyond the lip of the
lid. Positioned in this manner allows a person to grab base 110 and
pull upward for removal of protrusion 120 (not shown) from a
consuming opening in the lid during use. Also, this embodiment of
apparatus 100, as a cantilevered structure, allows a person to grip
base 110 for replacing protrusion 120 into the consuming opening
(e.g., gripping with two fingers at a point on base 110 (perhaps
opposite sides) adjacent to or at an end opposite protrusion
120).
[0041] By filling the consuming opening of the lid of a beverage
container, embodiments of apparatus 100 are capable of blocking
(e.g., sealing) the opening such that liquid contained within the
container does not spill out of the container through the consuming
opening or any spillage is minimized. In addition, by filling the
opening in the lid, embodiments of apparatus 100 aid in keeping a
hot beverage hot by preventing heat from escaping through the
opening in the lid.
[0042] FIG. 5 shows a plurality of lids capable of being stacked on
each other and each including another embodiment of apparatus 500.
Lids 510, 520 and 530 each have a conical shape with apex 535 (as
viewed) having a diameter less than a diameter of base 540 of the
lid. In one embodiment, base 540 fits over the lip of a beverage
container and seals the lid to the container. Base 540 defines an
opening into the lid. Apex 535 of each lid is defined by a superior
surface. The superior surface has a cavity extending into one or
more quadrants defining conical, circumferential body 550 of the
lid having the consuming opening formed therein (not shown). Body
550 has front lip 554 extending toward base portion 540 of the lid
defining an external perimeter plane 558 of the lid. Also, body 550
has rear lip 564 extending toward base portion 540 of the lid
defining interior plane 568 of the lid.
[0043] As shown in FIG. 5, this embodiment of apparatus 500 (three
shown) includes an angled base 510. Base 510, in the embodiment
shown, is angled such that base portion 512 is angled to conform to
the conical shape defined by the different diameter of apex 535 and
base 540 (plane 558) of front lip 554 of body 550 of beverage
container lids 510, 520 and 530 to allow for stacking of lids 510,
520 and 530 while protrusion 520 is blocking (plugging) the
consuming opening of lids 510, 520 and 530. In addition, base
portion 512 may form any angle which would allow other lid to be
stack upon a lid containing apparatus 500. The embodiment shown in
FIG. 5 and similar embodiments may either be disposable or reusable
and may be formed of any of the materials discussed above.
[0044] In addition, FIG. 5 shows base portion 514 of base 510. Base
514, in one embodiment, is angled to conform to the conical shape
defined by the different diameter of apex 535 and base 540 (plane
568) of rear lip 564 of body 550 of the beverage container lid to
assist in keeping apparatus 500 in place while engaged with a
consuming opening of the lid. It is contemplated that base portion
514 may form any angle with respect to rear lip 564, even if base
portion 514 functions in a non-securing manner.
[0045] In one embodiment, apparatus 500 only includes base portion
512. In another embodiment, apparatus 500 only includes base
portion 514. It is contemplated that apparatus 500 may contain
neither base portion 512 or base portion 514 but only protrusion
520 mounted on base 510 of such a size to lie directly over body
550 of the lid without any portion of base 510 protruding over the
raised edge of the lid. In addition, base portions 512 and 514, in
some embodiments, may not be angled, but instead extend parallel
and/or perpendicular (e.g., similar to the plane of a straw
protruding from the consuming opening) to apex plane 538 of the
lid.
[0046] FIG. 6 shows apparatus 100 connected to a key chain. Once a
key chain or key chain is inserted through aperture 130, apparatus
100 is capable of being transported. In addition, apparatus 100, in
one embodiment, is durable and capable of being used a plurality of
times. Moreover, it is contemplated that any material and/or device
may be inserted through aperture 130 for transport of apparatus
100. Also, in one embodiment, aperture 130 is of a sufficient size
and shape that apparatus 100 may be directly connected to another
object for transportation.
[0047] FIG. 7 shows another embodiment of a plug attached to a key
chain. This embodiment includes ring 720 with which apparatus 700
may be attached to another object. In FIG. 7, ring 720 is connected
to a clasp of a key chain for easy removal from the key chain. In
addition, it is contemplated that any method suitable for
connecting apparatus 700 to another object may be used. For
example, base 710 may form a clasp shape or any shape that may be
clasped by a clasping or attaching mechanism.
[0048] FIGS. 8-11 show another embodiment of an apparatus suitable
for blocking (e.g., sealing) an opening in a lid of a beverage
container to inhibit the escape of liquid from the container
through the lid. In the embodiment shown, apparatus 600 includes
base 610 having a linear or planar profile including surface 615
and opposing surface 625. In this embodiment, base 610 has a
circular shape. It is appreciated that other shapes e.g.,
rectangular, including a square, triangular, elliptical, etc., may
be suitable. In the embodiment shown in FIGS. 8-11, base 610 as a
circle has a diameter on the order of one to two inches although
shorter or longer diameters may be suitable. Base 610, in one
embodiment, has a diameter sufficient to accommodate a protrusion
having dimensions suitable to fit within a consuming opening of a
lid of a beverage container. The diameter may be of a sufficient
size such that it is grippable by a consumer of a beverage
container and may be gripped, for example, between a finger and
thumb to be removed or placed on a lid of beverage container.
[0049] Apparatus 600 shown in FIGS. 8-11 includes protrusion 620
having a core extending in a perpendicular direction from a surface
of base 610 (in this embodiment, surface 615 of base 610).
Protrusion 620, in one embodiment, has dimensions, e.g., a length
and a width, suitable to fit within at least a portion of a
consuming opening of a lid. Referring to FIGS. 9-11, protrusion 620
includes first portion 630 and second portion 635 each meeting at
junction 638. Protrusion 620 protrudes from surface 615 of base
610. Protrusion 620, in one embodiment, has a thickness, T,
including portion 630 and portion 635, sufficient so that when base
610 lies on a surface of a lid of a beverage container, protrusion
620 protrudes or extends a distance from a surface of the lid
sufficient to protrude or extend into a consuming opening in a lid
to block (e.g., plug) the opening. A suitable protrusion distance
or thickness, T, is approximately 0.12 inches or greater. In one
embodiment, where a superior surface of a lid of a beverage
container has a consuming opening defined therein, a protrusion
distance or thickness, T is approximately 0.5 inches with portion
630 having a thickness of 0.125 inches and portion 635 having a
thickness of 0.375 inches.
[0050] Base 610 and protrusion 620 of apparatus 600 may each be of
a plastic material with base 610 of sufficient rigidity to render
it suitable to be placed on a lid of a beverage container. A
sufficient rigidity may be defined, in part, by a thickness of a
material for the base (as measured between surface 615 and surface
625). A representative thickness is on the order of 0.25 inches.
Base 610 and protrusion 620, may be formed as a single integral
unit of a plastic material by, for example, molding techniques.
[0051] Referring to FIG. 10, in one embodiment, portion 630 and
portion 635 of protrusion 620 are defined by sidewall portions that
are angled differently with respect to surface 615 of base 610.
Sidewalls of portion 630 extend from surface 615 at an angle less
than 90.degree., while sidewalls of portion 635 extends from
surface 615 or a projection drawn through surface 615 at an angle,
.beta., of 90.degree. or greater. In one embodiment, portion 630 of
protrusion 620 is defined by beveled sidewalls having an angle,
.alpha., of 60.degree. to 85.degree. relative to surface 615.
Portion 635, on the other hand, includes sidewall portions defined
by an angle, .beta., of 90.degree. or more, preferably, beveled
relative to the surface at an angle, .beta., of
95.degree.-120.degree..
[0052] In the embodiment described where portion 630 of protrusion
620 includes sidewalls angled (beveled) at angle, .alpha., less
than 90.degree., junction 638 has a perimeter at least equivalent
to, but preferably greater than a perimeter of a consuming opening
of a lid of a beverage container. In one embodiment, apparatus 600
has protrusion 620 sufficient such that portion 635 and portion 630
extend into the consuming opening. In other words, when inserted
into a consuming opening of a lid of a beverage container, portion
635 of protrusion 620 extends completely through the consuming
opening as does junction 638 while portion 630 extends through the
consuming opening as far as such point of when surface 615 contacts
a surface of the lid of the beverage container.
[0053] For a typical lid of a beverage container made out of a thin
plastic material and having a consuming opening formed within the
plastic material, protrusion 620 may be inserted through the
consuming opening with portion 635 having a perimeter less than a
perimeter of the consuming opening (defined by sidewalls having an
angle, .beta., less than 90.degree.). Protrusion 620 will fit
through the consuming opening until portion 638 having a perimeter
greater than a perimeter of the consuming opening. At such point,
the consuming opening may be expanded by the continued force of
advancing protrusion 620 into the consuming opening. Thus, in one
embodiment, protrusion 638 is made of a material sufficiently rigid
enough to deform material defining a consuming opening of a
beverage container when forced into the opening.
[0054] Once junction 638 is through the consuming opening, the
sidewalls of protrusion 620 taper inward defined by portion 630
having an angle, .alpha., less than 90.degree.. In this manner, the
plastic material may relax and approach a pre-deformed shape
(deformed by junction 638). In one embodiment, the sidewalls
defining portion 630 tapers from a perimeter near junction 638 that
is greater than the consuming opening to a perimeter near surface
615 that is less than or equal to a perimeter of the consuming
opening. Thus, as the material of the lid that defines the
consuming opening relaxes, it relaxes against the sidewalls of
portion 630 of protrusion 620.
[0055] FIG. 12 shows a side view of apparatus 600 above a lid of a
beverage container (lid 710). In this embodiment, surface 615 of
base 610 faces a superior surface (as viewed) of lid 710. Lid 710,
in one embodiment, is detachable from a beverage container (e.g., a
disposable beverage container) and has a conical shape with apex
735 (as viewed) having a diameter less than a diameter of base 740
of lid 710. In one embodiment, base 740 fits over a lip of a
beverage container and seals the lid to the container. Base 740
defines an opening into the lid. Apex 735 of lid 710 is defined by
a superior surface. The superior surface has a cavity extending
into one or more quandrants defining conical, circumferential body
750 of lid 710 having consuming opening 754 formed therein.
[0056] FIG. 13 shows a side view of apparatus 600 and a top view of
a portion of lid 710. Lid 710 includes consuming opening 754
defined in body 750. In the embodiment shown, consuming opening 754
has an oval or stadium shape of a width, W1, on the order of one
half inch. In this embodiment, apparatus 600 includes protrusion
620 also having an oval or stadium cross-sectional shape (see FIG.
8). As seen in FIG. 13, portion 635 of protrusion 620, in this
embodiment, has a distal end having sidewalls defined by a
perimeter less than a perimeter of consuming opening 754 in lid
710. The angled sidewalls of portion 635 in this embodiment
decrease the perimeter of protrusion 620 between a proximal and a
distal end of portion 635. Thus, while a distal end of portion 635
may have a perimeter that is less than a perimeter of consuming
opening 754, portion 635 will have a perimeter equivalent to the
perimeter of contact opening 754 towards its proximal end.
[0057] A proximal end of portion 635 and a distal end of portion
630 define junction 638. As shown in FIG. 13, junction 638 has
sidewalls that define a perimeter greater than a perimeter of
consuming opening 754. FIG. 13 demonstrates this by showing
protrusion 620 at junction 638 having a width, W2, greater than W1.
For example, where a width, W1 of consuming opening 754 is 0.5
inches width, W2 of protrusion 620 at junction 638 may be 0.56
inches to 0.62 inches.
[0058] Portion 630 of protrusion 620 is defined by a proximal end
at a surface of base 615 and a distal end at junction 638. Portion
630 has a perimeter that increases from one that is less than a
perimeter of consuming opening 754 to one that is greater than
consuming opening 754 (at junction 638).
[0059] FIGS. 14-16 show side views illustrating the placement of
apparatus 600 within consuming opening 754 of lid 710. As shown in
FIG. 14, protrusion 620 of apparatus 600 is aligned over consuming
opening 754 and a distal end of portion 635 of protrusion 620 is
placed within consuming opening. FIG. 14 shows that a distal end of
portion 635 has a perimeter less than a perimeter of consuming
opening 754 (illustrated by width, W1). FIG. 15 shows further
advancement of protrusion 620 into consuming opening 754 of lid
710. As shown in FIG. 15, protrusion 620 is advanced into consuming
opening 754 such that junction 638 is at a point corresponding to
consuming opening 754. Junction 638 has a perimeter (defined by
width, W2) greater than a perimeter of consuming opening 754. To
advance junction 638 of protrusion 620 through consuming opening
754 where junction 638 has a perimeter greater than a perimeter of
consuming opening 754, the consuming opening must expand by
deforming a material of lid 710. FIG. 15 shows lip 775 of a
material of lid 710 being deformed (pushed downward as viewed) to
expand the perimeter of consuming opening 754 to that of junction
638 of protrusion 620. In one embodiment, lid 710 is formed of a
thin plastic material that gives lip 775 a perceived memory to
spring or return to its original configuration once a force (e.g.,
a downward force of protrusion 620 at junction 638) is removed.
[0060] FIG. 16 shows the further advancement of protrusion 620 into
consuming opening 754. As illustrated in FIG. 16, portion 630 of
protrusion 620 is advanced through consuming opening 754. The
angled sidewalls of portion 630 define a perimeter (illustrated by
width, W3) that is less than a perimeter at junction 638. The
smaller perimeter allows lip 775 defining consuming opening 754 to
relax and consuming opening 754 to return to a smaller perimeter.
FIG. 16 shows lip 775 defining consuming opening 754 approaching a
horizontal profile compared to the curved profile in FIG. 16. The
advancement of protrusion 620 through consuming opening 754 may
continue until surface 615 lies on a surface of lid 710,
essentially inserting an entire portion of portion 630 of
protrusion 620 into consuming opening 754. It is appreciated, that
the advancement need not proceed such that an entire portion of
portion 630 is in consuming opening 754. Regardless, the angle of
tapered diameter of portion 630 to a perimeter that is less than a
perimeter at junction 638 secures apparatus 600 to lid 710. In an
embodiment where a perimeter of portion 630 about its length is
greater than a perimeter of consuming opening 754, lip 775 defining
consuming opening 754 will not be able to completely relax and
approach its original planar (e.g., horizontal) form. Thus, lip 775
will contact portion 630 of protrusion 620 and potential spillage
of contents of a cup to which lid 710 is affixed through consuming
opening 754 will be minimized or eliminated. In other words,
apparatus 600 may effectively seal consuming opening to minimize or
eliminate spillage through the consuming opening.
[0061] In the foregoing specification, the invention has been
