Definitions
- This disclosure relates to lids for drinking cups, and more specifically, to drink-through lids for beverage containers, and elements thereof or items used therewith to minimize or substantially avoid escape of liquids therefrom.
- Disposable beverage containers which may also be described herein as drinking cups or beverage cups—are ubiquitous for use in “on-the-go” consumption of liquids, particularly hot beverages such as coffee or tea.
- Disposable beverage cups often utilize a disposable lid.
- Various lid designs include openings therein, or openable portions therein, configured with the idea of minimizing splashing or spilling of the beverage from the container.
- a drink-through type lid that provides a horizontally oriented drink outlet on a top surface of a raised rim.
- Such a design allows a user to drink through the lid in a manner similar in many respects to drinking through a straw, in that it usually seems that a limited amount of liquid is provided through the small opening.
- lids with such openings may allow escape of liquid (especially when full), unless the drink outlet is sealed, such as by use of a stopper or plug. Consequently, spill prevention devices used with such designs do not allow drinking without subsequent removal of the stopper or plug.
- other disposable lids have been provided that include flip-open or rip-open tabs that lift to allow drinking, but which prevent drinking when such tabs are in an unopened or in a resealed condition.
- a lid design for a disposable beverage cup or container that simultaneously minimizes or avoids spill of liquid from the beverage cup or container, while allowing the user to drink from the cup or container without first manipulating a flip-open or rip-open tab. It would be even more advantageous for such a lid design to be provided in a low cost, disposable material. It would be additionally desirable if such a lid design were available in a configuration that is easy to ship, compact for storage, and easy to install at point of sale. Further, it would be desirable if such a lid enhanced ease of use, by substantially preventing liquid spill during transport, while allowing drinking without the necessity of manipulating a flip-open, rip-open, slide-open, or removable component.
- Novel spill resistant tabs have been developed for use with drink-through type beverage container lids. Concurrently, drink-through lid designs have been developed which may receive and secure therein such spill resistant tabs. In various embodiments, such spill resistant tabs significantly enhance a user's beverage drinking experience as compared to various prior art drink-through lids for beverage containers.
- Various embodiments of novel spill resistant tabs allow prevention, or at least minimization of liquid spills from a cup or beverage container, while allowing a user to drink from the cup or beverage container without the necessity of first manipulating a closure mechanism, such as prior art flip-up or rip-open tabs, or removable closure features such as plugs or stoppers.
- the combination of a drink-through lid and a spill resistant tab are provided.
- the drink-through lid may include a slit sized and shaped for passage therethrough of a blade portion of a spill resistant tab.
- the drink through lid may include a land that is sized and shaped for receiving a handle portion of a spill resistant tab.
- the handle portion may further include an ear portion, which may be slightly upturned for ease of manipulation of the spill resistant tab by a user.
- At least one drink outlet is provided.
- the at least one drink outlet may be defined by a first edgewall extending upward into the interior portion of the hollow raised lip portion, and by an elongated second edgewall extending along an outlet portion of the drink well base in proximity to the peripheral edge.
- a portion of the at least one drink outlet may be oriented along a first surface extending from the elongated second edgewall at an angle alpha ( ⁇ ) in the range of from about forty five degrees (45°) to about ninety degrees (90°).
- the first surface may be a planar surface.
- a portion of the at least one drink outlet may be oriented along a second surface extending along the drink well base.
- the second surface may be a planar surface.
- the drink outlet may be defined as if the first surface and the second surface are joined along a radiused curve.
- a first planar surface and a second planar surface may be joined as if along a radiused curve.
- an inwardly protruding shoulder may be provided from the interior portion of the hollow raised lip portion, and the drink outlet may be defined by an opening cut along the inwardly protruding shoulder.
- the inwardly protruding shoulder may be arcuate in shape, with an upwardly directed arching central portion.
- a drink well base for containing liquid is provided in a drink-through lid.
- the drink well base has a sloped floor extending upwardly from a peripheral side along the lower end portions.
- the drink well base may be located above the bottom edge of the rim and below the outer lip portion.
- the lowest portion of the floor of the drink well base may be located at or near the vertical level of the center line of the interior bead sealing portion.
- the lowest portion of the floor of the drink well base may be located below the center line of the interior bead sealing portion.
- the drink well base may be located vertically at a level that is below the center line of the interior bead sealing portion, or higher.
- the drink well base includes an underside surface, oriented toward the interior of a beverage container, when in use.
- a drink-through lid may be provided including a downwardly extending wall extending transversely across the drink-through lid.
- the drink-through lid may include downwardly extending walls including a valley portion.
- the valley portion may be located along a portion of a chord line of the drink-through lid, or along a diameter line of the drink-through lid.
- the valley portion may include V-shaped walls.
- a slit may be provided along a length of the valley portion.
- the downwardly extending V-shaped walls may be parallel to the elongated second edgewall of the drink-through drink outlet.
- the downwardly extending wall may be provided in a continuous shaped surface from edge to edge of the drink-through lid.
- the V-shaped wall may be provided as a partial segment, or as a partial diameter, that does not extend to either edge of the drink-through lid.
- a slit may be provided at the bottom of the V-shaped groove.
- a slit of length LS defined by first and second ends, may be provided across at least a portion of the drink-through lid.
- the slit may be perforated.
- the slit may be further defined by a first edge and by a second edge in downwardly extending walls. Such downwardly extending walls may include at least portions of the noted V-shaped wall.
- a slit may be utilized for locating a spill resistant tab therein.
- a drink-through lid including a slit may also be used on a beverage cup without a spill resistant tab inserted therein.
- the spill resistant tab may include a blade portion sized and shaped for passage through the slit when the spill resistant tab is being placed into a working position.
- a spill resistant tab may also be provided with dimensions that provide locking features vis-a-vis a drink-through lid, to securely locate a spill resistant tab with respect to the lid.
- the spill resistant tab may be locked into a position which provides close fitting engagement between an upper surface of the blade portion and the underside of the drink well.
- the spill resistant tab may include a connector portion to link the handle portion and the blade portion.
- the connector portion may be sized and shaped for placement into a secure mating engagement position with a portion of the drink-through lid, such as the valley.
- the connector portion when in a working position, may be placed into secure mating engagement with a portion of the V-shaped walls.
- the connector portion may be provided in a generally planar configuration.
- a fold may be provided such that there is a first hinge point between the proximal end of the handle and the connector portion, and a second hinge point between the connector portion and the proximal end of the blade portion.
- the spill resistant tab may be secured in a working position, wherein the blade portion is located near or adjacent the underside of a drink well. In such a location, the blade provides a barrier between the drink outlet and the interior of a beverage container.
- the blade portion of spill resistant tab may include a blade edge that is edge sized and shaped for close fitting engagement near, or against, an arcuate portion of the inner sidewall of a beverage container in which the spill resistant tab is placed.
- the blade edge may be radiused to provide a relatively constant gap G distance between the blade edge and the interior sidewall of a beverage cup. In such manner, upward flow of liquid from the interior of a beverage container is substantially prevented, as liquid must flow circumferentially above the blade, and then upward through a drink outlet and into the drink well, before escaping. Thus, direct splash of liquid from the interior of a beverage container, outward through the drink outlet, is effectively prevented.

Description
- This application is a continuation and claims priority under 35 USC § 120 of prior U.S. patent application Ser. No. 14/178,248 filed Feb. 11, 2014, (U.S. Pat. No. 9,751,665 B2, issued on Sep. 5, 2017), entitled DRINK-THROUGH BEVERAGE CONTAINER LIDS WITH SPILL RESISTANT TABS, the disclosure of which incorporated herein in its entirety, including the specification, drawing, and claims, by this reference.
- Not Applicable.
- A portion of the disclosure of this patent document contains material that is subject to copyright protection. The patent owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.
- This disclosure relates to lids for drinking cups, and more specifically, to drink-through lids for beverage containers, and elements thereof or items used therewith to minimize or substantially avoid escape of liquids therefrom.
- Disposable beverage containers—which may also be described herein as drinking cups or beverage cups—are ubiquitous for use in “on-the-go” consumption of liquids, particularly hot beverages such as coffee or tea. Disposable beverage cups often utilize a disposable lid. Various lid designs include openings therein, or openable portions therein, configured with the idea of minimizing splashing or spilling of the beverage from the container.
- One type of disposable lid that is now widely used is a drink-through type lid that provides a horizontally oriented drink outlet on a top surface of a raised rim. Such a design allows a user to drink through the lid in a manner similar in many respects to drinking through a straw, in that it usually seems that a limited amount of liquid is provided through the small opening. Unfortunately, and especially during transport, lids with such openings may allow escape of liquid (especially when full), unless the drink outlet is sealed, such as by use of a stopper or plug. Consequently, spill prevention devices used with such designs do not allow drinking without subsequent removal of the stopper or plug. Similarly, other disposable lids have been provided that include flip-open or rip-open tabs that lift to allow drinking, but which prevent drinking when such tabs are in an unopened or in a resealed condition.
- Thus, there remains a need to provide a lid design for a disposable beverage cup or container that simultaneously minimizes or avoids spill of liquid from the beverage cup or container, while allowing the user to drink from the cup or container without first manipulating a flip-open or rip-open tab. It would be even more advantageous for such a lid design to be provided in a low cost, disposable material. It would be additionally desirable if such a lid design were available in a configuration that is easy to ship, compact for storage, and easy to install at point of sale. Further, it would be desirable if such a lid enhanced ease of use, by substantially preventing liquid spill during transport, while allowing drinking without the necessity of manipulating a flip-open, rip-open, slide-open, or removable component.
- Novel spill resistant tabs have been developed for use with drink-through type beverage container lids. Concurrently, drink-through lid designs have been developed which may receive and secure therein such spill resistant tabs. In various embodiments, such spill resistant tabs significantly enhance a user's beverage drinking experience as compared to various prior art drink-through lids for beverage containers. Various embodiments of novel spill resistant tabs allow prevention, or at least minimization of liquid spills from a cup or beverage container, while allowing a user to drink from the cup or beverage container without the necessity of first manipulating a closure mechanism, such as prior art flip-up or rip-open tabs, or removable closure features such as plugs or stoppers.
- In an embodiment, the combination of a drink-through lid and a spill resistant tab are provided. In an embodiment, the drink-through lid may include a slit sized and shaped for passage therethrough of a blade portion of a spill resistant tab. In an embodiment, the drink through lid may include a land that is sized and shaped for receiving a handle portion of a spill resistant tab. In an embodiment, the handle portion may further include an ear portion, which may be slightly upturned for ease of manipulation of the spill resistant tab by a user.
- In the drink-through lid, at least one drink outlet is provided. The at least one drink outlet may be defined by a first edgewall extending upward into the interior portion of the hollow raised lip portion, and by an elongated second edgewall extending along an outlet portion of the drink well base in proximity to the peripheral edge. In an embodiment, a portion of the at least one drink outlet may be oriented along a first surface extending from the elongated second edgewall at an angle alpha (α) in the range of from about forty five degrees (45°) to about ninety degrees (90°). In an embodiment, the first surface may be a planar surface. In an embodiment, a portion of the at least one drink outlet may be oriented along a second surface extending along the drink well base. In an embodiment, the second surface may be a planar surface. In an embodiment, the drink outlet may be defined as if the first surface and the second surface are joined along a radiused curve. In an embodiment, a first planar surface and a second planar surface may be joined as if along a radiused curve. In an embodiment, an inwardly protruding shoulder may be provided from the interior portion of the hollow raised lip portion, and the drink outlet may be defined by an opening cut along the inwardly protruding shoulder. In an embodiment, the inwardly protruding shoulder may be arcuate in shape, with an upwardly directed arching central portion.
- In further detail, a drink well base for containing liquid is provided in a drink-through lid. In an embodiment, the drink well base has a sloped floor extending upwardly from a peripheral side along the lower end portions. In an embodiment, the drink well base may be located above the bottom edge of the rim and below the outer lip portion. In an embodiment, the lowest portion of the floor of the drink well base may be located at or near the vertical level of the center line of the interior bead sealing portion. In an embodiment, the lowest portion of the floor of the drink well base may be located below the center line of the interior bead sealing portion. In various embodiments, the drink well base may be located vertically at a level that is below the center line of the interior bead sealing portion, or higher. The drink well base includes an underside surface, oriented toward the interior of a beverage container, when in use.
- In an embodiment, a drink-through lid may be provided including a downwardly extending wall extending transversely across the drink-through lid. In an embodiment, the drink-through lid may include downwardly extending walls including a valley portion. In an embodiment, the valley portion may be located along a portion of a chord line of the drink-through lid, or along a diameter line of the drink-through lid. The valley portion may include V-shaped walls. A slit may be provided along a length of the valley portion. In an embodiment, the downwardly extending V-shaped walls may be parallel to the elongated second edgewall of the drink-through drink outlet. In an embodiment, the downwardly extending wall may be provided in a continuous shaped surface from edge to edge of the drink-through lid. In an embodiment, the V-shaped wall may be provided as a partial segment, or as a partial diameter, that does not extend to either edge of the drink-through lid.
- In an embodiment, when a V-shaped groove is provided, across at least a portion of a drink-through lid, a slit may be provided at the bottom of the V-shaped groove. In an embodiment, a slit of length LS, defined by first and second ends, may be provided across at least a portion of the drink-through lid. In an embodiment, the slit may be perforated. In an embodiment, the slit may be further defined by a first edge and by a second edge in downwardly extending walls. Such downwardly extending walls may include at least portions of the noted V-shaped wall. In an embodiment, a slit may be utilized for locating a spill resistant tab therein. However, a drink-through lid including a slit may also be used on a beverage cup without a spill resistant tab inserted therein.
- In an embodiment, the spill resistant tab may include a blade portion sized and shaped for passage through the slit when the spill resistant tab is being placed into a working position. In an embodiment, a spill resistant tab may also be provided with dimensions that provide locking features vis-a-vis a drink-through lid, to securely locate a spill resistant tab with respect to the lid. In an embodiment, the spill resistant tab may be locked into a position which provides close fitting engagement between an upper surface of the blade portion and the underside of the drink well.
- The spill resistant tab may include a connector portion to link the handle portion and the blade portion. In an embodiment, the connector portion may be sized and shaped for placement into a secure mating engagement position with a portion of the drink-through lid, such as the valley. In an embodiment, the connector portion, when in a working position, may be placed into secure mating engagement with a portion of the V-shaped walls. In an embodiment, the connector portion may be provided in a generally planar configuration. When the connector portion is provided in a generally planar configuration, and at least proximal end of the blade portion is provided in a generally planar configuration, and at least the proximal end of the handle is provided in a generally planar configuration, then a fold may be provided such that there is a first hinge point between the proximal end of the handle and the connector portion, and a second hinge point between the connector portion and the proximal end of the blade portion. In a secure mating engagement position, the spill resistant tab may be secured in a working position, wherein the blade portion is located near or adjacent the underside of a drink well. In such a location, the blade provides a barrier between the drink outlet and the interior of a beverage container. Further, in an embodiment, the blade portion of spill resistant tab may include a blade edge that is edge sized and shaped for close fitting engagement near, or against, an arcuate portion of the inner sidewall of a beverage container in which the spill resistant tab is placed. In an embodiment, the blade edge may be radiused to provide a relatively constant gap G distance between the blade edge and the interior sidewall of a beverage cup. In such manner, upward flow of liquid from the interior of a beverage container is substantially prevented, as liquid must flow circumferentially above the blade, and then upward through a drink outlet and into the drink well, before escaping. Thus, direct splash of liquid from the interior of a beverage container, outward through the drink outlet, is effectively prevented.
