TECHNICAL FIELD
[0003] The present invention relates to drinking straws.
BACKGROUND
[0004] The increased popularity of fast-food establishments,
coupled with the popularity of consumption of food and beverages on
the go, have led to the need for more convenient and safer takeout
packaging.
[0005] Currently, a consumer wishing to drink from a takeout
beverage container has two standard options: sipping the beverage
through a sip hole in the lid of the beverage container, as is
common for hot drinks such as coffee; or sucking the beverage
through a straw placed into the beverage container, as is common
for drinks consumed cold, such as sodas. Sip holes, typically used
for hot beverages, require the consumer to take small sips to avoid
scalding. While many consumers would prefer a controlled or
regulated delivery of their hot beverage, standard straws do not
allow for the liquid to cool to a comfortable temperature before
reaching the consumer's mouth and thus have the potential to cause
burns. Both straws and sip holes can be hazardous when the consumer
is engaged in an activity, such as driving or walking, that
requires maintaining eyes forward to watch the path ahead, and
which may involve sudden stops. The consumer may have to look down
and away from the road while drinking from a straw or may have
forward vision obstructed by the beverage container while tipping
it back to drink via a sip hole. Straws are also potentially
dangerous if the consumer's head decelerates quickly while
drinking, for example when braking unexpectedly during a drive. In
that case, the straw may stab the consumer in the roof of her or
his mouth. While some straws incorporate a flexible portion to
allow the consumer to keep eyes forward, they do not eliminate this
risk of stabbing, and further must be sized particularly for each
height of beverage container.
[0006] Existing takeout beverage and food containers are also
inconvenient, requiring the consumer to set aside a sandwich to
take a drink, for example; or, in the case of a beverage container
with a lid that accepts a snap-on food container, the food
container must be decoupled in order for the consumer to sip a hot
drink through a sip hole.
[0007] Moreover, billions of disposable beverage cups are used
every year. Often those cups are part of a larger meal, and current
technology dictates placing a lid on the beverage cup, and packing
the food in a separate and detached container. This may be
satisfactory for a consumer seated at a table. However, when the
consumer must eat on the go, use of the current technology is
problematic. Consider, for example, a consumer who is drinking a
beverage and would like to access a breakfast sandwich in a takeout
bag. The consumer must set aside the beverage, and then use one
hand to hold the bag and the other hand to access the sandwich,
then set aside the bag and use both hands to open the sandwich
packaging. As shown in this example, current technology does not
allow for convenient on-the-go consumption. Standard cup lids are
simple covers that do not include an integrated container. Rather,
known lids cover the contents of a cup which forms a closed
container in combination with the cup itself
[0008] To address some of these problems, yogurt manufacturers have
placed a small food container on the lid of a yogurt cup. The food
container (often holding nuts or granola) must be removed from the
yogurt cup and then flipped over and opened, then the contents are
poured into the yogurt cup. It is therefore not possible to
simultaneously access the contents of the yogurt cup and the
contents of the food container; rather, the food container must be
completely disengaged from the cup to access either the contents of
the yogurt cup or the contents of the food container. The food
container that attaches to the yogurt cup in an upside-down
position has a limited food-volume capacity because its walls taper
as they proceed upward toward the bottom of the upside-down
container. Without this tapering, the yogurt cup/food container
complex would become top-heavy and cumbersome.
[0009] Other known devices having a container or shelf combined
with a lid have limitations which makes these devices impractical
to use. One category of devices includes a container combined with
a cup, but utilizes a hole in the middle of the lid. This makes it
impossible to store relatively circular items, i.e., non-ring or
non-annular items having no central hole, in the container, such as
hamburgers, cookies or muffins, for example. Another category of
devices includes a container combined with a lid, but does not
allow for simultaneous access to the contents of the cup and the
container, nor for the container to be resealed or a drop-in
container to be removed from the container. Other devices that
include drop-in functionality require removal of the container
before accessing the contents of the cup. Other devices have
relatively small peel containers for pills such as mints and are
not suitable for larger food items. Another category of devices
utilizes dividers in the cup with access on each side of the cup.
No known devices have a non-permanent or male/female bottom
oriented coupling system for coupling a container with the lid.
[0010] Also known in the art is a flask-type container with a small
compartment for a pill or pills. This design is unsuitable for
storage of and simultaneous access to larger volumes of beverages
and more substantial snacks/food items such as would be consumed by
a take-out customer, and does not have a shape compatible with
armrest cup-holders.
[0011] Thus simultaneous or intermittent access to the contents of
known cups and the contents of an attached container is not
possible. This makes for difficult consumption of coffee, soda,
snacks, popcorn, etc., in malls, fast food restaurants, theaters,
amusement parks, sports stadiums or in any other venue. For
example, this makes it difficult to eat and drink food in a theater
or stadium with one cup-holder per seat.
[0012] What is therefore needed is a straw and cup lids that
overcome these drawbacks and fosters convenient on-the-go
drinking.
SUMMARY
[0013] The present invention provides an elegant solution to the
needs described above and provides numerous additional benefits and
advantages as will be apparent to persons of skill in the art.
[0014] One aspect provides a container lid that can be coupled to a
food container, wherein the lid includes a continuous outer
coupling trough for attachment to the open top of a beverage
container and where the trough circumscribes a footprint of the
container lid. A straw-hole planar surface is disposed within the
footprint, the straw-hole planar surface is adjacent to the outer
coupling trough and a hole for drinking a liquid in the container
extends through the straw-hole planar surface. A riser wall extends
away from the straw-hole planar surface and defines a first planar
surface above the straw-hole planar surface. A sip hole extends
through the first planar surface. A food container coupling wall
connects to the first planar surface and extends from the first
planar surface to a position lower than the first planar surface
and a food container coupling bottom connected to the food
container coupling wall.
[0015] In another aspect, a cup lid with an integrated container
that can be coupled to a beverage cup has a continuous outer
coupling ring which circumscribes a footprint of the lid, and a
drink-hole planar surface above the coupling ring and within the
lid footprint. An annular surface above the coupling ring, within
and non-concentric with the lid footprint, is connected to the
drink-hole planar surface. A food container has a container inner
wall extending downward from the annular surface, and a bottom
connected to the container inner wall and coplanar with or below
the coupling ring to avoid spillage. A drink hole for drinking a
liquid in the cup extends through the drink-hole surface at a
position outside of the annular surface. The drink hole may be a
straw hole or a sip hole. A cover is removably attached to the
annular surface and encloses the food container. The cover may be a
seal-on/peel-off membrane, and may be sealed on the lid in any
rotational orientation due to the circular shape of the food
container.
[0016] In one embodiment, the drink-hole planar surface is
approximately co-planar with the coupling ring and connected to the
annular surface by a container outer wall extending upward from the
drink-hole planar surface to the annular surface. In another
embodiment, the drink-hole planar surface is above the coupling
ring and connected to the coupling ring by an exterior wall
extending upward from the coupling ring to the drink-hole planar
surface, and connected to the annular surface by a container outer
wall extending upward from the drink-hole planar surface to the
annular surface. In another embodiment, the drink-hole planar
surface is above the coupling ring and connected to the coupling
ring by an exterior wall extending upward from the coupling ring to
the drink-hole planar surface. In this embodiment, the drink-hole
planar surface is contiguous with the annular surface.
[0017] Also disclosed is a rack for holding the lids in a compact
arrangement as for sale. For display on a rack, the drink-hole
planar surface may be positioned at an optimal distance between the
coupling ring and the annular ring that allows the lid to hang in a
substantially vertical orientation when suspended via a horizontal
post through the drink hole, when the container is filled with a
food item.
[0018] The foregoing summary is illustrative only and is not meant
to be exhaustive. Other aspects, objects, and advantages of this
invention will be apparent to those of skill in the art upon
reviewing the drawings, the disclosure, and the appended
claims.

DETAILED DESCRIPTION
[0083] Following is a non-limiting written description of example
embodiments illustrating various aspects of the invention. These
examples are provided to enable a person of ordinary skill in the
art to practice the full scope of the invention without having to
engage in an undue amount of experimentation. As will be apparent
to persons skilled in the art, further modifications and
adaptations can be made without departing from the spirit and scope
of the invention, which is limited only by the claims. In the
following description, numerous specific details are set forth in
order to provide a thorough understanding of the present invention.
Particular example embodiments of the present invention may be
implemented without some or all of these features or specific
details. In other instances, components well known to persons of
skill in the art have not been described in detail in order not to
obscure unnecessarily the present invention.
[0084] FIG. 1 illustrates the straw 10 used in a beverage container
20. The straw is similar to the one disclosed in U.S. patent
application Ser. No. 29/500266 entitled "BENDABLE DRINKING STRAW"
filed on Aug. 22, 2014, which is by the same inventor of the
present application and is incorporated herein by reference. The
straw 10 may optionally be pre-shaped with an arc shape, and is
flexible as described in more detail with reference to FIG. 10. The
straw 10 may also be semi-rigid such that it returns to its
original shape when it is not under a bending force. The straw 10
may be made of a compliant material such as plastic or composite,
to allow it to reversibly deflect as described in more detail with
reference to FIG. 10. Because the straw 10 may be pre-formed with
an arc shape, the consumer can drink from the straw from a natural
horizontal position, keeping her or his gaze 30 forward. This is
important when the consumer's gaze cannot be diverted, for example
when the consumer is driving a vehicle and would like to take a sip
through the straw without looking away from the road ahead. As
shown in FIG. 2, with a conventional straw 40, the consumer's gaze
50 is diverted when drinking.
[0085] Previous straw designs addressed this problem with a short
section of the straw that was bendable with an accordion-like
structure. The portion of the straw on either end of the
accordion-like structure was straight, and bending the
accordion-like structure could create a 90-degree turn such that
the user would access the end of the straw in the horizontal
position. But as discussed below, when these accordion-like
bendable straws are used with a top-mounted snap-on food container
that may be larger than the beverage container lid, the straw must
be sized in relation to the height of each particular type of
beverage container, thereby reducing their utility.
[0086] FIGS. 3A, 3B and 3C illustrate the same straw 10 placed into
three beverage containers of different depths 20A, 20B, 20C. The
straw 10 exits the beverage container with about the same amount of
vertical clearance. This takes on more importance when the beverage
container only has limited vertical clearance. For example, in FIG.
4, the beverage container 20D has a food container 60 placed on top
it. Such a food container is disclosed in the applications listed
at the beginning of this application, the disclosures of which are
fully incorporated herein by reference. But as shown at position
70, the food container 60 restricts the amount of vertical
clearance of a straw 10. A conventional accordion-like bendable
straw would need to be specifically manufactured for the precise
depth of the container 20D. If the food container 60 were placed on
a shorter beverage container (for example container 20A of FIG.
3A), yet another straw would need to be manufactured that was
shorter. Because of the bendable characteristics of the straw 10,
which may optionally be arc-shaped, (shown in more detail in FIGS.
3A, 3B and 3C), a single straw can be used with various heights of
beverage containers.
[0087] FIGS. 6 and 7 illustrate two cross sectional shapes of the
straw 10, with FIG. 6 having a larger opening 80 for thicker
beverages such as milkshakes and FIG. 7 having a narrower opening
90 for hot beverages such as coffee. It would be apparent that
other cross sectional shapes are possible.
[0088] FIG. 8 is an isometric view of the straw 10 intended to show
the arc-shape. FIG. 9 is a side view showing the arc-shape. In the
embodiments shown, the straw has more than a 20-degree arc and is
approximately 12 inches long. It would be apparent that other arc
angles and lengths are possible.
[0089] In addition to the safety feature of allowing a consumer to
drink in a natural horizontal position without diverting her or his
gaze, the straw also is compliant so as to minimize stabbing that
is common with a conventional straw. FIG. 10 illustrates a consumer
drinking from the straw 10 even when experiencing a force that
propels the consumer's head forward in the direction of arrow 100.
The straw 10 bendably deforms to position 110 from position 120. A
convention straw 40, shown in in FIG. 11, would stab the consumer
in the same situation. If, for example, a consumer was driving and
held the beverage container in an orientation to maintain a forward
gaze as in FIG. 11, and that consumer experienced a force such as
hard braking that propelled the consumer's head forward in the
direction of arrow 130, the straw 40 would not bend and would stab
the inner portion of the consumer's mouth 140. Also, when the straw
40 bends, the cross-sectional area of the straw does not collapse
or crimp. The straw 10 is constructed such that the amount of force
necessary to bend the straw does not cause discomfort to the user's
mouth. In one embodiment, the amount of bending force necessary is
between 0.02 N and 0.2 N. The straw 10 may be made more rigid, but
the bending force would then also increase, possibly causing
discomfort to the user's mouth.
[0090] A further feature of the straw concerns its ability to
regulate or cool hot liquids during use to prevent burns. FIGS.
12A-12F illustrate a straight and bendable straw 10 used in a
beverage container. The bendable drinking straw is designed such
that it can bend at least 180 degrees as shown in FIGS. 12D and
12F. The straw may also be optionally pre-formed in an
arc-shape.
[0091] Currently, hot liquids are delivered from a beverage
container to the consumer via a sip hole that allows a user to tip
the container and sip the hot liquid. It is the sipping that allows
the liquid to cool, preventing scalding. Because the bendable straw
can be used for hot beverages, it is helpful that the length and
internal surface area of the straw allows the liquid to cool when
it travels from the beverage container to the consumer's mouth.
Conventional circular straws (by circular, it is meant the cross
section) do not allow for safely bending or deflecting off a top
mounted food container, nor do they sufficiently regulate or cool a
hot liquid. For this reason, consumers do not use a conventional
circular straw for consuming hot beverages. Rather, the bendable
straw disclosed herein may be used to have a properly sized
cross-sectional area and length such that the amount of liquid
entering the consumer's mouth is properly regulated or cooled, and
therefore will not scald the user. This is especially helpful when
the user is performing some other task while consuming the
beverage. For example, a user who is driving would prefer to use a
straw to consume the hot beverage such that his or her gaze is not
diverted or obstructed by having to tilt the beverage container to
access the liquid from the sip hole.
[0092] FIGS. 12A and 12B depict the flow analysis of four bendable
straw configurations shown in FIG. 12C. The OH parameter (or the
system rating number) is a qualitative measure of the amount of
head caused by the straw and is calculated by the following
equation:
OH=(Friction Factor.times.(L/Hydraulic Diameter)).times.((Velocity
2)/(2*Gravimetric Acceleration))
[0093] Each of these parameters is calculated and presented in FIG.
12B. The higher OH parameter (i.e., the head) the more the straw is
able to dissipate heat so as to reduce the temperature of the
beverage as it moves through the straw. Another factor shown in
FIG. 12B is the cross-sectional area and the velocity, the product
of which is the volume of liquid delivered to the user. System 1
has a low OH, meaning that the straw allows less heat to escape
from the liquid and the volume of liquid delivered to the user is
about 0.0473 in 3/s. So while the straw allows less heat to escape
from the liquid, the amount of liquid actually delivered is very
small and reduces the possibility of scalding. A user may not
prefer such low volume delivery. System 4 has a higher OH, meaning
that the straw will allow more cooling, and the volume of liquid
delivered to the user is much higher (10.times.) at about 0.537 in
3/s. While the user would like the additional volume, the OH value
suggests that the liquid delivered may be too hot. The combination
of high volume and high temperature runs the risk of scaling.
Systems 2 and 3 have OH values of 0.23 and 0.19 inches
respectively, with a volume delivery of 0.297 in 3/s. This
combination of OH value and volume is the "sweet spot" where a user
is delivered a pleasant amount of warm beverage, while reducing the
possibility of scalding. The optimal straw design is therefore
shown by system 2 and 3, with the dimensions provided in FIGS.
12A-12C. It would be apparent that the various parameters could be
varied to reach an optimal volume/temperature profile for the straw
without departing from the spirit of this invention. Those
parameters may include but are not limited to the physical
dimensions of the straw, the straw material, and the roughness of
the straw. (A straw that has more internal roughness would increase
the OH and reduce the temperature). Further, the dimensions may be
chosen such that the straw can easily bend without causing the
straw to collapse and thereby unreasonably restrict flow. The
bending of the straws (systems 1-4) is shown in FIGS. 12D-12F.
[0094] FIGS. 13A-13I illustrate a lid 200 for a beverage container
215, than can be detachably connected to a food container 205. A
bendable straw, as discussed with reference to FIGS. 12A-12F, may
be inserted into a punch-out straw hole 225. A lid 200 has a
continuous outer coupling trough 210 for attachment to the open top
of the beverage container 215. The lid 200 also has a straw-hole
planar surface 220 that is adjacent to the outer coupling trough
210. A hole 225 for drinking the liquid in the container extends
through the straw-hole planar surface 220. Riser wall 230 extends
away from the straw-hole planar surface 220 and defines a first
planar surface 235 above the straw-hole planar surface 220. A sip
hole 240 for drinking the liquid also extends through the first
planar surface 235. To connect the lid 200 to the food container
205, the lid 200 may have a food container coupling wall 245
connected to the first planar surface 235 that extends down from
the first planar surface 235 to a position lower than the first
planar surface 235. The food container coupling wall 245 may also
include a pressure structure 270 that places pressure against the
food container 205 when a food container 205 is coupled to the lid
200. The pressure exerted by the pressure structure 270 is selected
so as to allow the secure coupling of the food container 205 to the
lid 200, and allow the decoupling of the food container 205 from
the lid 200. The lid 200 may also have a vent hole 275 to relive
pressure buildup caused by hot beverages.
[0095] A food container coupling bottom 250 is connected to the
food container coupling wall. The straw hole planar surface 220 may
also have a straw hole cover 255 and a hinge 260, wherein the straw
hole cover rotates about the hinge and exposes the hole 225 when a
straw is punched through the hole 225. To prevent the straw hole
cover 255 from inadvertently opening, it may have a tick 265 that
connects it to the straw hole planar surface 220. The straw hole
220 may have a substantially rectangular shape with rounded corners
280, which would accommodate the straw 10 disclosed above.
[0096] One benefit of having the straw hole cover 255 is that a
user may prefer to use the sip hole 240. If the straw hole 225 does
not have a cover 255, rather it is an open hole, the user may
inadvertently spill the hot beverage while tilting the beverage cup
during sipping from the sip hole 240. The straw hole cover 255
prevents this spillage. It further allows a retailer to use a
single hot beverage lid for multiple users. Likewise as shown in
FIG. 13B, when the food container 205 is coupled to the lid 200,
the sip hole 240 is substantially covered by the food container
205, while the straw hole 225 is not covered by the food container
205. Thus if the user prefers to use a straw and consume the food
from the food container 205, the beverage will not spill from the
sip 240 when the food container 205 is coupled.
[0097] An embodiment of a cup lid with integrated container 1300b
is shown in FIG. 16, coupled with a cup 1330, with a
seal-on/peel-off membrane 1310b and configured to allow access to
the contents of the cup via a straw 1301a. FIG. 17 illustrates a
cross sectional view of FIG. 16. As shown, the cup may be a soda,
lemonade, coffee, or beer cup, for example, and is not limited to
cups with a rolled rim, which are shown herein in an exemplary
manner. A first solid or liquid 1320 may include any combination of
one or more cookies, chocolates, chips, crackers, nuts, popcorn,
candies, ice cream, frozen yogurt, fruit pieces, burgers, French
fries, sandwiches, milk, cream or any other item. A second liquid
or solid in cup 1330 may include any combination of ice cream,
milkshake, frozen ice, ice coffee, milk, lemonade, water, soda,
coffee, beer, mixed alcoholic beverage, or any other item.
[0098] FIG. 18 illustrates a top perspective view of the embodiment
of the invention shown in FIG. 16. The planar, horizontal area on
top of the embodiment shown includes a hole 1305a, which may be a
straw hole or sip hole, to allow access to the second liquid or
solid, i.e., the contents of the cup. Without removing the cup lid,
a person may also access the contents of the container on top of
the cup. FIG. 19 illustrates a top view of the embodiment of the
invention shown in FIG. 16. The peel-off tab is shown at the bottom
of the figure and allows for the seal-on/peel-off membrane 1310b to
be removed from the cup lid.
[0099] FIG. 20A illustrates a side cross-sectional view of the
embodiment of the invention shown in FIG. 16. FIG. 20B illustrates
a side cross-sectional view of the embodiment of the invention
shown having two or more coupling elements configured to couple
with cups of different sizes. In this figure, more than one
coupling element, here 1307, having different diameters are
employed so that embodiments of the invention may fit different
sized cups. For example, the embodiment shown in FIG. 20B may be
sized to couple with large or small coffee cups or large or small
soda cups. In addition, three or more coupling elements 1307 may
also be employed having three or more differing diameters, so that
embodiments of the invention may couple with small, medium and
large cups as one skilled in the art will appreciate. In this
manner, only one size of cup lid, albeit with as many diameter
coupling elements as desired, may be utilized to accommodate the
different sized cups utilized. Although the embodiment shown has
vertically offset coupling elements, other embodiments may utilize
coupling elements that are horizontally offset without a vertical
offset, as one skilled in the art will appreciate. FIG. 20C
illustrates different embodiments of coupling elements that may be
utilized with embodiments of the cup lid. The cross section of a
coupling element 1307a is similar to the coupling element 1307, and
may be easier to decouple from the cup lid based on the large angle
at the bend 1377a. The cross section of a coupling element 1307b is
a harder-to-remove version of the coupling element 1307 based on
the smaller angle at the bend 1377b, which requires more force to
remove from the rolled edge of a cup, for example. The cross
section of a coupling element 1307c shows a semi-permanent or
permanent coupling element based on the hook-like sharp angle at
the bend 1377c. Depending on the stiffness of the material utilized
in construction of the cup lid, the sharp angle at the bend 1377c
may allow for the entire cup, even if full of liquid, to be lifted
by the cup lid. This prevents spills by keeping the cup lid and cup
attached even with large forces involved. As one skilled in the art
will appreciate, multiple diameter coupling elements (as shown in
FIG. 20B) on one cup lid may utilize any combination of the
coupling elements 1307a, 1307b or 1307c in any embodiment of the
invention. For example, in one embodiment, the smallest diameter
coupling element on the top portion of FIG. 20B may utilize the
coupling element 1307a or 1307b while the lower coupling element on
the bottom portion of FIG. 20B may utilize the coupling element
1307b or 1307c, for example to allow for more strength for large
cups that may weigh more. Any number of different diameters may be
utilized with any embodiment of the coupling element and any other
coupling element known in the art may be utilized if desired and
based on the application, as one skilled in the art will
appreciate.
[0100] FIG. 21 illustrates an exploded view of an embodiment of a
cup lid 1300a with an integrated container or cavity 1301a shown
above the cup 1330, along with any solid/liquid 1320 or food item
such as a cookie, for example, that fits into the cavity 1301a, and
a cover 1310a that covers the food item while the food item is in
the container 1301a. The cup lid 1300a includes a coupling element
1307 that allows the cup lid to couple with the cup, and includes
at least one wall 1302 that leads to a container bottom 1303, which
may also be considered part of the wall 1302. As used herein, the
term "wall" is not limited to a surface of any shape, but rather
refers to the separation between the container 1301a and the
contents of the cup 1330. Specifically, embodiments of the
invention include at least one wall that defines the container
1301a that is configured to store a first solid or a liquid
separate from a second solid or liquid stored in the cup 1330
wherein the cup 1330 generally includes an annular opening that
lies in a plane on top of the cup. The cup as shown also includes a
rolled rim 1331 that a coupling element 1307 is configured to
couple with to hold the cup lid 1300a onto cup 1330. Specifically,
the coupling element 1307 is configured to couple at least one wall
to the annular opening on top of the cup, for example by stretching
over the smaller diameter portion of the coupling element to allow
the rolled edge of the cup to fit into the slightly larger diameter
portion of the cup lid. The coupling element 1307 is an exemplary
form of attachment and any form of attachment may be utilized to
couple the cup lid 1300a to the cup 1330, as one skilled in the art
will appreciate, including a coupling element that includes a more
difficult type of coupling to remove or even a permanent coupling.
The container cover 1310a is optionally configured to couple via a
coupling element 1322 to a coupling element 1321 of the cup lid
1300a. An alternative is to extend the vertical sidewall of 1310a
such that the coupling element 1322 is configured to couple to the
coupling element 1307 of cup lid 1300a. The horizontal area 1304
includes a hole 1305a for a straw or sip hole and optional indented
cut-outs 1306. At least one wall is configured to enable access of
the first solid or liquid and the second solid or liquid without
disengagement of the coupling element. For example, the contents of
both the integrated container 1301a and the cup 1330 are accessible
without removing the cup lid. The cover 1310a as shown is
configured as an external wall friction press-on cover, but may
also be configured as a seal-on/peel-off membrane, press-on
friction dome, press-on friction dome with hole, internal and
external wall friction press-on, internal wall friction press-on,
hinge or rotational cover, so long as the cover is configured to at
least partially enclose the container and retain the contents of
the container when the cover is coupled with a corresponding
version of the cup lid.
[0101] FIG. 21A illustrates a bottom view of an embodiment of the
invention. At least one wall 1302 includes a vertical dimension
that extends to, into, out of, or both into and out of the plane
defined by the annular opening of the cup. FIG. 21B shows a side
view of an embodiment of the invention having a vertical dimension
that extends down to the plane of the cup opening. FIG. 21C shows a
side view of an embodiment of the lid container with a cup shown in
dashed lines, having a vertical dimension that extends into the
plane of the cup opening; this vertical dimension may be of any
size. Furthermore, at least one wall 1302 includes a horizontal
dimension, for example across the diameter of the container, having
a width less than, equal to, or greater than a width measured
across the annular opening of the cup. The embodiment shown in FIG.
21C may itself hold popcorn and fit into a standard popcorn cup
that is then utilized for soda, and/or may fit into a cup that has
a narrower, or stepped configuration on the bottom half of the cup
so as to fit into a standard stadium or movie theater seat cup
holder for example. Any type of cup that allows for an embodiment
of the invention to be utilized in conjunction with a cup holder
for an automobile, or stadium seat, movie theater seat or any other
type of cup holder is in keeping with the spirit of the
invention.
[0102] FIGS. 14A-14P illustrate another embodiment of the invention
in which the food container is circular and off-center. A lid 1100
for a beverage cup has a container portion 1110 that may hold food
which is sealed by a seal/peel-off membrane 1104. This press-fit
seal is disclosed in U.S. Pat. No. 8,596,491 entitled "CUP LID WITH
INTEGRATED CONTAINER" issued on Dec. 3, 2013, by the same inventor
of the present application. This patent is incorporated herein by
reference.
[0103] FIG. 14A illustrates an embodiment of the cup lid with
integrated container, where a straw hole 1106 passes through a
horizontal area or straw-hole surface 1102a. The straw-hole surface
is approximately co-planar with a coupling ring 1108 used to mate
the lid 1100 with a beverage cup. The coupling ring 1108
circumscribes a footprint of the lid 1100. Although a circular
straw hole is shown, the hole could be of another suitable shape,
such as a rounded rectangular sip hole for drinking without a
straw. The coupling ring 1108 may be a coupling element as
discussed above with reference to U.S. application Ser. No.
13/680011.
[0104] FIG. 14B illustrates another embodiment where the straw hole
1106 is through a shelf 1102b between the plane defined by the
coupling ring 1108 and the seal-on/peel-off membrane 1104. FIG. 14C
illustrates an embodiment where the straw hole 1106 is through a
shelf 1102c approximately co-planar with the seal-on/peel-off
membrane 1104.
[0105] FIG. 14D shows the embodiment of the cup lid where the straw
hole is in the lower position, with the seal-on/peel-off membrane
1104 removed. The seal-on/peel-off membrane 1104 attaches
releasably to the annular surface 1118 which is connected to the
straw-hole surface 1102a via an outer food container wall 1112. The
cavity or food container 1111 is further defined by an inner
container wall 1114 which descends from the annular surface 1118 to
a substantially flat bottom 1116, which is at or below the level of
the coupling ring 108 to avoid spillage of the contents of the
container. The inner container wall 1114 defines a second
footprint, which forms a nested circle within the footprint of the
lid 1100. As shown in FIG. 14D, the second footprint defined by the
inner container wall 1114 is non-concentric to the larger footprint
of the lid 1100.
[0106] FIG. 14E shows the embodiment of the cup lid where the straw
hole 1106 is in the middle position, and FIG. 14F shows the
embodiment where the straw hole 1106 is in the upper position, with
the seal-on/peel-off membrane 1104 lifted off. For both of these
embodiments, an exterior wall 1117 extends from the coupling ring
1108 to the straw-hole plane 1102b, 1102c. The exact position of
the straw hole in this last embodiment may be optimized as
discussed below.
[0107] FIGS. 14D, 14E and 14F further show that the design of the
lid 1100 is such that the seal-on/peel-off membrane 1104 can be
sealed on the lid 1100 in any rotational orientation. As shown, the
food container 1111 is circular, thus making the manufacture of the
lid 1100 much easier because when food is placed in the container
1111 the seal-on/peel-off membrane 1104 need not be oriented in a
certain direction prior to installation.
[0108] FIGS. 14G, 14H and 14I illustrate the lid 1100 with a
typical straw 1107 inserted through the straw hole 1106 in the
straw hole plane 1102a (lower position), 1102b (middle position),
and 1102c (upper position). FIGS. 14J, 14K and 14L are cutaway
views of these three lid embodiments with the straw and a cup
1120.
[0109] Further disclosed is a rack 1150 designed to be used with
the lids 100. As shown in FIGS. 14M and 14N, the rack 1150, which
may be made of metal, plastic or another suitable material, has a
base 1152 so that the rack may stand upright on a countertop or
other horizontal surface. Vertical supports 1154 rise from the base
1152 and are connected by horizontal supports 1156 from which
extend posts 1158. The lids 1100 can be suspended from the posts
1158 in a compact display for sale, for example. In FIG. 1M, the
first embodiment of the lid 1100 is shown which has the straw hole
1106 approximately co-planar with the coupling ring 1108 used to
mate the lid 1100 with the beverage cup (FIG. 14A, 14D, 14G, 14J).
The problem with this embodiment is that when the container 1111 is
filled with food (for example, nuts or candy), gravity (shown by
arrow 1160) will cause the lid 1100 to rotate about the straw hole
1106 in the direction of arrow 1165. Thus when the lids 1100 are
displayed on the rack 1150, they will be tilted, unless a secondary
support 1157 is added to the rack 1150 to prevent such rotation. In
FIG. 14N, the straw hole 1106 is between the plane defined by the
coupling ring 1108 and the seal-on/peel-off membrane 1104 (FIG.
14B, 14E, 14H, 14K). The exact position is selected such that the
lid 1100, when filled with food, has a weight distribution which
causes it to dangle on the rack 1150 in a substantially vertical
orientation (arrow 1175), as may be seen also in FIG. 14O.
[0110] FIGS. 14P, 14Q and 14R illustrate tooling to allow the quick
and easy installation of the seal-on/peel-off membrane. A support
structure 1180 has a shape complementary to the container portion
1110, such that the container portion 1110 fits over the support
structure 180 which reinforces the container portion 1110. This
reinforcement allows the seal-on/peel-off membrane 1104 to be
installed during manufacture by a press fit, without damaging the
container portion 1110. As shown in FIG. 14P, the support structure
1180 has a base 1182 and a cavity 1189 defined by an inner wall
1184 connected by an annular upper surface 1188 to an outer wall
1186. As shown in FIGS. 14Q and 14R, when the container portion
1110 is placed over the support structure 1180, the coupling ring
1108 rests against the base 1182 and the annular surface 1118 is
supported by the upper surface 1188, while the container inner wall
1114 and outer wall 1112 touch the tooling inner wall 1184 and
outer wall 1186, respectively. This allows the seal-on/peel-off
membrane 1104 to be sealed over the food container 1111 without
risk of damage to the container portion 1110 when pressure is
applied to create the seal.
[0111] FIGS. 15A-15F illustrate another lid for a beverage cup,
wherein the container lid 2200 has a compartment 2211 that may hold
food. As shown in FIG. 15A, the container lid 2200 attaches to a
cup lid 2201 on a cup 2220, and a straw 2207 may be used to access
a drink in the cup 2220 while the container lid 2200 is attached.
The compartment 2211 may have one or more removable shelves 2202 as
shown in FIG. 15B, to contain multiple food items. As shown in FIG.
15E, a cover 2250 pivots about a hinge 2255 to allow access to the
compartment 2211, and the shelves 2202 may have a hole 2216 to
allow the user to easily remove a shelf 2202 to access food
contained on a lower shelf. The food compartment 2211 of the lid
2200 may have one or more ledges 2205, 2210 upon which the shelves
2202 rest (see FIG. 15F). As illustrated in FIGS. 15C and 15D, the
container lid 2200 has a coupling element 2230 which attaches to a
corresponding coupling element 2240 on the cup lid 2201.
[0112] The straw may be constructed out of plastics, composites or
other suitable materials. The straw may also be semi-rigid such
that it returns to its original shape when it is not under a
bending force.
