Abstract
A lid for a beverage container is described. The lid has a basin that is designed to enhance the user's olfactory experience when drinking a beverage from the container and lid. As the user tilts the container and lid to take a drink, the beverage pours through an opening on the basin valley and flows across a sipping surface area to the user's mouth, thus allowing the beverage to aerate, evaporate, and cool. The basin is sized and dimensioned to channel and concentrate the vapor rising from the beverage towards the user's nose as the user sips the beverage. The basin and the opening are sized and dimensioned to provide a comfortable and secure feeling when drinking hot beverages. In this manner, the lid enhances the drinker's olfactory experience and provides better controllability of the flow of a hot beverage to prevent burn injuries.

(26) Lid 100 is removably coupled with container 101.
(27) In other embodiments, lid 100 and container 101 can be removably coupled using threaded engagements, snap fittings, male-female engagements, or any other fastener suitable for sealing a liquid within lumen 102. In yet other embodiments, lid 100 and container 101 can be permanently coupled. For example, lid 100 and container 101 could be manufactured as one integral structure and a liquid could be placed inside lumen 102 prior to completion of the manufacturing process.
(28) Lid 100 and container 101 can be made of any material suitable for containing a liquid (e.g., the material is substantially impermeable to the liquid). Lid 100 and/or container 101 can also be made of a material that helps insulate the temperature of the beverage from the temperature of the surrounding environment. The material may also be configured and/or chosen to withstand sudden temperature changes and have relatively low manufacturing costs (e.g., raw materials are inexpensive; material can be used in low cost manufacturing processes). Lid 100 and/or container 101 could also include a thermochromic material to indicate the temperature of the beverage or peizochromic material around edges of lid to indicate a proper seal with the beverage cup. In addition, lid 100 and/or container 101 could be made of a biodegradable material to reduce negative environmental impact when disposed. Lid 100 could also be made of a disposable or non-disposable material. As used herein, non-disposable material means a material that is configured for withstand many uses. In some embodiments, a non-disposable material could still comprise a material that is environmentally friendly and/or biodegradable. Contemplated materials include, but are not limited to, high-density polyethylene (HDPE), polystyrene, polypropylene (PP), polyethylene terephthalate (PET), silicone material, bio-plastics, fiber-based materials, metal alloys, ceramics, composites, and any combination thereof.

(30) Basin 310 has a slit opening 401 (e.g., slot, spout, etc.) disposed on the surface of the valley. Opening 401 is slightly concave and matches the contour of ridge 311 at the drinking portion of lid 100. In other embodiments, opening 401 could be substantially planar. Opening 401 is sized, dimensioned, and positioned to provide an outlet for dispensing the liquid. In alternative embodiments, opening 401 can comprise numerous shapes other than slits, such as a circular opening (see e.g., opening 2101 in
(31) In some embodiments, opening 401 is located at an optimal distance from the proximal ridge (or from the wall of the container) so as to prevent a specific volume of the beverage from being dispensed. In this manner, the lid prevents unwanted coffee grinds or sediment such as from tea from being dispensed.
(32) Basin 310 also has second opening 402 that is sized, dimensioned, and positioned so as to allow air flow while avoiding liquid flow when dispensing liquid from opening 401. Second opening 402 helps to maintain atmospheric pressure within lumen 102 when the liquid is dispensed. However, it is contemplated that other means can be used to help maintain atmospheric pressure, such that second opening 402 is not needed (e.g., larger openings for outlet dispensing).
(33)
(34) Opening 401 has a width 306 of approximately 0.6 inches (approximately 1.524 centimeters) and an opening height 308 of approximately 0.045 inches (approximately 0.1143 centimeter). The surface area of opening 401 is about 0.027 inches.sup.2 (0.1742 cm.sup.2). This particular size, shape, and position of opening 401 allows for better control of the delivery of an average cup of coffee. More specifically, the size, shape, and position of opening 401 provide an optimal flow rate for beverages having similar viscosity and surface tension as coffee. If opening 401 is substantially larger, the flow rate is too fast and the user may be burned (coffee is generally served at a temperature of between 155 degrees Fahrenheit (68.33 degree Celsius) and 175 degrees Fahrenheit (79.44 degree Celsius). However, if opening 401 is substantially smaller, the surface tension of coffee can cause the coffee to build up at opening 401, which may eventually burst and cause an unexpected flow of hot coffee.
(35) Those of ordinary skill in the art will appreciate that alternative sizes, shapes, and positions for opening 401 could be used while still providing an acceptable flow rate and controlled flow (e.g., no vacuum or surface tension build up). For example, other sizes and dimensions that still result in a surface area of approximately 0.027 inches.sup.2 may still eliminate the surface tension build-up while providing an acceptable flow rate for hot beverages. Unfortunately, conventional lids that place the spout opening at the bottom of a valley and away from the user's lips (e.g., GB 2473041 and GB 2473042) typically have a spout opening that is either too too large or too small for hot beverages. When the opening is too large, the user would either have to wait until the hot beverage has cooled before taking a drink or else risk being burned. When the opening is too small, surface tension of the beverage creates build-up and trapping of the liquid at the opening; a sudden break in the surface tension leads to an unexpected rush of hot beverage, potentially causing burn injuries. Neither approach is acceptable since the user must compromise safety (e.g., being burned) or taste (e.g., drinking lukewarm coffee).
(36) The exact size, shape, and position of opening 401 can be varied according to any number of factors, such as the beverage (e.g., juice, coffee, hot chocolate, tea, wine, water, soda, ice cream shake), beverage temperature (e.g., hot or cold), other beverage characteristics (e.g., viscosity, surface tension, presence or absence of whip cream or solids) and user environment (e.g., sitting, walking, driving). In some embodiments, opening 401 can be adjustable (see for example lid 200 in
(37) Lid 100 also has a second opening 402. Second opening 402 can have a second opening diameter 407 of approximately 0.1406 inches (approximately 0.3571 centimeters).
(38) The specific values for dimensions as described herein are not meant to restrict the scope of the subject matter presented unless otherwise specified in the claims.
(39) Basin 310 is also configured to channel and concentrate vapor rising from the liquid in the sipping portion to aroma portion. This is accomplished by shaping basin 310 such that its width becomes narrower moving from one end of its length (i.e., the drinking portion) to the other end of its length (i.e., the aroma portion).
(40) One advantage of lid 100 is the prevention of burning a user's upper lip. Ridge 311 of basin 310 includes two sidewalls that meet with the drinking portion at angles 480 and 481, as shown in
(41)
(42) As illustrated by the cross-sectional side view in
(43) In addition,
(44) It should be noted that lid 100 has various slopes that can benefit the user and/or the manufacturers.
(45) Lid 100 also has a drinking portion width 504, which is the distance from opening 401 to outward-facing wall 312 of ridge 311. Width 504 defines a capture area that is sized and dimensioned to capture a small amount of liquid and/or liquid constituents (e.g., coffee grinds, contaminants from backwash drinkers, etc.). The capture area defined by width 504 can be used to prevent dispensing of unwanted portions of a beverage. In some embodiments, drinking portion width 504 can be approximately 0.4 inches (approximately 1.016 centimeters). In alternative embodiments, width 504 can be smaller or larger, depending on the desired size of the capture area. In yet other embodiments, the capture area can completely eliminated by being filled in.
(46)
(47) Angle 501 and angle 502 could vary depending on numerous factors such as user preference and the particular application (e.g., tea, coffee, hot chocolate, juice, child, adult, etc). Angle 501 and angle 502 could also vary along the circumference of ridge 311 (e.g., different portions of the ridge could have different angles).

(70) From a method perspective, when a user wishes to imbibe the beverage, the user would place their bottom lip near the edge of ridge at drinking portion. The user would tilt the container allowing the liquids to flow through openings in a controlled manner. The liquids would collect within sipping area. Simultaneously, opening would allow the exchange of air between lumen of container and the surrounding environment, thus preventing a vacuum (e.g., backpressure) from forming (which could disrupt the even flow of the liquids from opening). The user would then be able to sip the liquids at their leisure. Through the aforementioned process, users are able to prevent the sudden and uncontrolled rush of potentially searing hot fluids from hitting their lip and mouth.
(71) The lids described above may provide numerous advantages over prior art lids. Some of those advantages will now be described.
(72) Many of the embodiments give the user greater control over the flow rate of the beverage, which is particularly advantageous for drinking hot coffee or hot tea. In addition, the plastic can be naturally torn upward when pinched forward at the base of the slit opening in the reservoir. This creates a larger opening for liquid to pass through where the original slit was, increasing the flow. However it will not widen the point at which it comes into contact with the user's mouth. This feature provides a distinct advantage over prior art lids. The tapered narrow lip design at the top of the front of the lid is not affected from the tear so the user's control of sloshing while drinking is still intact. This design feature can be implemented when the user would like to increase flow of beverage in instances when the liquid is not at a temperature above 140 degrees Fahrenheit (60 degree Celsius) or when beverage is of a more viscous nature such as drinks with whipped topping. This increase of flow with the larger opening option may not be recommended while liquid is above 140 degrees Fahrenheit (60 degree Celsius) and uncomfortably hot for the user, since an increased flow can create a heightened chance of burning or discomfort to the user while consuming, especially while on the go.
(73) Embodiments that include a slit spout opening provide better control of flow rate, meaning the appropriate volume of liquid is being delivered to the user at an appropriate velocity for a given beverage temperature (i.e., a sufficient amount of liquid is being delivered to the user at any given moment and at a comfortable speed). The controlled flow helps to reduce the risk of burning.
(74) Most embodiments can be modified to include small cuts along the interior ridges running up the basin walls from the corners of the front slit such that the opening can be enlarged by pinching the bottom of the opening. This allows the user to adjust the opening size and the flow rate. For example, as a hot beverage cools down, the user may wish to increase the flow rate. Also, if a user is no longer moving, the user may wish to increase the flow rate. Or if the user has finished drinking a liquid portion of the beverage and wants to consume a foamy whipped topping, the user may increase the opening.
(75) Some embodiments give the consumer the option to increase flow without widening the channel of point of entry where liquid enters user's mouth. By simply pinching together the front spout at the front slit opening, the plastic will naturally and easily tear up towards the top without affecting the channel or exterior.
(76) Some embodiments could be further enhanced by two simple cuts rising up from the corners of the front slit spout. The cuts could follow the natural creases of the interior. The cuts would not leak any liquid unless pushed open by user, which would control flow and change flow only if desired.
(77) Embodiments that have the increased opening feature also guarantees that the user can get every last drop of the drink. There is no trapped liquid when this option is exercised.
(78) The increased opening feature is also beneficial for someone who is not on the go (e.g., someone sitting at their desk at the office) but would like to keep their beverage covered to keep it warmer longer. Since the user is not in motion, the user can afford to increase the flow by increasing the opening, which will also enhance the olfactory experience.
(79) Many of the embodiments above also provide safety splash and spill advantages. For example, the basin walls act as a splash guard and reduces the chances that the user will be burned when the beverage container is jolted (e.g., user drives over a bump in the road). In addition, if the beverage container is accidentally tipped over, the restricted opening reduces flow rate of the liquid and thus reduces the amount of spilt liquid. Moreover, if the container is shaken, the lid reduces spill and has a sloping basin valley that returns liquid to the container, unlike most conventional lids where the liquid has nowhere to come to rest. With a conventional lid the consumer may be burned by the liquid that pools on the outer surface of the lid, which could have very serious consequences when the consumer is operating a vehicle.
(80) Many embodiments provide an enhanced olfactory experience since the basin valley provides an area for liquid to collect and slowly flow back into the container reservoir at a controlled flow rate. The liquid is given time to aerate and, when the lid is tilted, the basin walls act to channel and concentrate aroma vapors towards the user's nose.
(81) In addition, a large basin valley (e.g., recessed reservoir) allows for a larger vacuum hole (e.g., 0.125 inches (0.3175 centimeters) to 0.1875 inches (0.4762 centimeters)) compared to many prior art lids. This larger vacuum hole ensures a smoother flow from the drink spout up front and helps to guarantee that liquid will not be trapped in the container. In the event some liquid is released from the vacuum hole, it will be safely returned to the container leaving an aromatic coating of liquid behind. The large surface area of the basin valley creates a larger aromatic coating, thus enhancing the consumer's olfactory experience.
(82) In some embodiments the basin has an angular shape. With the unique angular shape the user can quickly identify where the drinking spout is without looking at the container. This is beneficial in situations where visibility is low (e.g., at night or in a dark room) or when the user just needs to keep their eyes on the road while driving in heavy traffic.
(83) In many embodiments, the basin valley does not dip below the rim of the cup, which allows the consumer to fill the cup all the way up. Most embodiments are designed to be stackable so that space is conserved when multiple lids are stored and/or transported.
(84) Many embodiments also make it easy for the barista to quickly identify the drinking spout area of the lid so that there will be less of a chance that he/she will come into contact with it and thus limiting the chance of cross contamination.
