Container Lid Assembly with Locking Handle and Additive Cartridge Chamber

This application claims priority to U.S. Provisional Patent Application Ser. No. 63/645,200, entitled “Drinking Container and Lid”, filed on May 10, 2024, the entirety of which is hereby incorporated by reference.

The present disclosure generally relates to lid and closure assemblies for containers for carrying fluid. More specifically, the present disclosure generally relates to container lid and closure assemblies having a user-actuated closure release, such as a push button, and a locking mechanism, such as a locking handle, to prevent accidental actuation. The disclosure also generally relates to lid and closure assemblies that are adapted to receive and utilize an additive cartridge for adding beverage ingredients, for example, to base liquid (water) as water is dispensed from the container.

Drinking containers may include lids with flip top closures. However, typical flip top closures for drinking containers are not adapted to accommodate or utilize additive cartridges and/or other components that may extend from or otherwise occupy space on or above the lid. Typical flip top closures are not readily adapted to accommodate, integrate or be compatible with an additive cartridge. Additionally, flip top closures may include latching mechanisms as well as latch locking mechanisms to prevent the accidental opening of flip top closures, for example, where the drinking container is placed in a dynamic environment, such as a backpack. The integration of an additive cartridge into a flip top lid environment where closure latching mechanisms and/or closure latch locking mechanisms are desired may thus present challenges.

Accordingly, there is a need in the art to address the above-mentioned shortcomings.

Disclosed is a lid assembly for use with a drinking container having an internal space configured to hold a base liquid and having a drinking container opening. The lid assembly can be configured to attach to the drinking container and can receive an additive cartridge. The closure can be coupled to the lid base and configured to move from a closed position in which the closure covers an additive cartridge receiving space, and an open position in which the additive cartridge receiving space is not covered. The lid assembly can include a lid base configured to attach to the drinking container and can include a lid base opening in which the additive cartridge can be received. The closure can be configured to comfortably accommodate an upper portion of the additive cartridge received in the lid base opening when the closure is in the closed position.

This disclosure relates to a lid assembly for use with a drinking container including a vessel having an internal space to hold a base liquid and a drinking container opening to the internal space.is a top, front perspective view of a lid assemblyin a closed position and attached to a container, according to an embodiment.show closurein a closed position andshow closurein an open position.is a side cross-sectional view (taken along linein) of the lid assembly in the closed position and attached to the container, according to an embodiment.is a side cross-sectional view (taken along linein) of the lid assembly in the open position and attached to the container, according to an embodiment. The lid assembly can generally include a lid base, a lid base opening, a cartridge chamber, a closure, a latching mechanism, and a handle. For example, as shown in, lid assemblyincludes a lid base, a lid base opening, a cartridge chamber, a closure, a latching mechanism (e.g., a latch ring, a push plateand a latch loop), and a handle. Lid base is configured to support or connect the individual components of lid assemblytogether. Lid baseis also configured to attach to drinking container. For example, lid basecan have an engagement portion configured to engage with drinking containerat drinking container openingto connect lid assemblyto drinking container. Closurecan be coupled to or supported on the lid baseto selectively cover drinking container openingand to cover other components of lid assembly.

Lid basecan be configured to receive cartridge chamberthrough lid base opening. In an assembled condition, cartridge chambercan extend from the lid base openinginto internal space. Cartridge chambercan define an additive cartridge receiving space. In some embodiments, the additive cartridge may include a treated or mixed liquid outlet. Additive cartridge may have internal features such as those described in U.S. Pat. No. 10,888,836 titled “Adjustable Additive Cartridge Systems and Methods,” which is incorporated by reference herein in its entirety. The additive cartridge and lid assemblymay be configured such that suction applied to the treated liquid outletcauses flow of the base liquid from internal spaceto the treated liquid outlet. The additive cartridge can be replaced by removing the additive cartridge from cartridge chamberthrough the lid base openingand inserting a new additive cartridge through the same lid base opening.

As previously mentioned, lid basecan have an engagement portion configured to engage with drinking containerat drinking container opening. For example, as shown in, lid basecan include a lid base walland an engagement portionextending from lid base walland configured to attach to drinking container. As shown in, engagement portioncan include a collar having a substantially annular shape. The collar may be configured to attach to drinking container opening. For example, the collar can be formed with collar threadsthat attach to drinking container threadsdisposed near drinking container openingin a mating fashion. In some embodiments, as shown incollar threads may be internal and drinking container threadsmay be external. In other embodiments, the threads on the collar may be external and the drinking container threadsmay be internal. Lid base wallmay lie in a plane perpendicular to a longitudinal axis of drinking containerin an assembled condition.

Lid assembly can include an umbrella valvedisposed within lid base wallto allow one-way airflow into the container interior spaceto prevent vacuum when contents are dispensed for drinking.

Lid basemay include a compartmentopposite engagement portion. Compartmentmay include an enclosing wallformed by a curved section having a substantially c-shape and a dimensioned section formed by a first post, a second post, and a base plate. When assembled with drinking container, engagement portionfaces drinking container, and compartmentfaces away from drinking container.

Compartmentcan comprise an annular channel formed by enclosing wall, an inner annular wall, and lid base wall. Lid base wallforms a bottom of the annular channel and is situated between enclosing walland inner annular wall. Lid base wallmay have a top surface that, when assembled with drinking container, faces away from drinking containerand a bottom surface that, when assembled with drinking container, faces toward drinking container.

Base platemay extend from the first postto second post. Base platemay have a consistent thickness throughout. Similarly, the curved section of enclosing wall that has a substantially c-shape may also have a consistent thickness throughout. First postand second postmay have a thickened cross-section in comparison with base plateand the section of enclosing wall that has a substantially c-shape. For example, as shown in, in some embodiments, first postand second postcan have a substantially triangular cross-section. The thickened cross-section of first postand second postcan provide reinforcement of lid baseand the hinge, such that lid baseand the hinge can withstand strain from repetitive pivoting movement of closureand handle. Additionally, the thickened cross-section provides reinforcement to protect lid assemblyfrom damage if drinking containeris dropped. The height of enclosing wallcan graduate from a point opposite base platetoward first post. The height of enclosing wallcan graduate from a point opposite base platetoward second post. The height of enclosing wallcan be highest at both first postand second post. The height of base platecan extend to a point below closureand the hinge in the assembled condition. In this way, enclosing wall, closure, and the hinge can fit together to enclose compartmentwhen closureis in the closed position. The height of enclosing wallcan be lowest at a point opposite base plate, such that enclosing wallallows access to lid base openingwhen closureis in the open position.

As shown by arrow B in, inner annular wallcan be configured to cause cartridge chamberand/or the drinking spout assembly to tilt at an angle with respect to a longitudinal axis A of drinking containerwhen in the assembled condition. In other words, when cartridge chamberis placed in lid base openingwith cartridge chamberrib resting on an edge of lid base opening, cartridge chamberis positioned/tilted at an angle with respect to longitudinal axis A of the drinking container, and with respect to a similarly oriented axis of lid assembly. The tilted angle of inner annular wall/lid base openingand cartridge chamberalone, or in combination with the shape of wall, makes it easier for insertion and removal of additive cartridge and/or cartridge chamberwithout interference of closureor other components. Additionally, the tilted angle of the components extending outwardly from lid basecan expose drinking spout assemblyfor drinking without interference of closureor other components. For example, a nozzle, spout, cartridge base, and an additive chambercan tilt at angle with respect to a longitudinal axis A of drinking containerwhen in the assembled condition. In this way, a user can easily insert and remove these components, as well as easily drink from the drinking spout assemblywithout closurecontacting hitting the user's face (excluding lips contacting drinking spout assembly).

Base platemay include a button openingconfigured to receive a push buttontherethrough. Push buttonmay be connected to the latching mechanism and may extend through base plateexposing push buttonsuch that push buttonis accessible for pushing from outside base plate. The thickness (perpendicular to the width and height) of base platemay be sufficiently thin to allow push buttonto be accessible when moving from a resting position () to a pushed position (). In the resting position, push buttondoes not apply pressure to push plate. In a pushed position, pressure has been applied to push buttoncausing push button to move toward push plate, thereby pressing latch ringtoward latching loop.

Cartridge chambercan be configured to be received by the lid base openingand to extend from the lid base openinginto internal space. Cartridge chambercan be configured to store an additive cartridge. In some embodiments, cartridge chambercan have an elongate shape extending between a cartridge chamber outletand a cartridge chamber inlet. For example, as shown in, cartridge chambermay have a substantially tubular shape. Cartridge chamberoutlet may be sufficiently wide to receive an additive cartridge. For example, in some embodiments, cartridge chamber outletmay be wider than the additive cartridge. The interior of cartridge chambermay have a shape corresponding to the shape of additive cartridge such that additive cartridge can be snuggly received within cartridge chamberto direct the base fluid from the inlet into the additive cartridge.

To retain an additive cartridge within cartridge chamber, the end of cartridge chamberadjacent cartridge chamber inletmay be narrower than the rest of cartridge chamber. For example, a diameter of cartridge chambermay taper toward cartridge chamber inlet. Cartridge chamber inletmay be narrower than cartridge chamber outletto promote suction of base fluid through cartridge chamber. Cartridge chambermay include cartridge chamber threadson an exterior surface near cartridge chamber outletto enable an additive cartridge to be attached to cartridge chamberby corresponding cartridge base collardisposed on the additive cartridge, as discussed below. Cartridge chambermay further include a cartridge chamber ribencircling cartridge chamber outlet. Cartridge chamber ribcan extend outwardly from an outer surface of cartridge chamber. Cartridge chamber ribmay be disposed adjacent to cartridge chamber threads. When cartridge chamberis inserted into lid base openingin an assembled condition, cartridge chamber ribcan rest upon lid base opening edgesuch that cartridge chamber threadsare exposed above lid base opening.

As shown in, additive cartridgecan include an additive chamberconfigured to hold an additive and to be received by cartridge chamber. For example, in some embodiments, additive chambercan include a pouch disposed within a cage having a tubular shape. Additive fluid can be disposed within additive chamber. Cartridge can comprise upper components, including a cartridge base, a cartridge outlet tube, nozzleincluding a treated liquid outlet, a flavor adjuster, and a drinking spout assembly. Cartridge basecan connect additive chamberto cartridge outlet tubeand nozzle. Cartridge basecan also connect cartridge outlet tubeand nozzleto flavor adjuster. Cartridge basecan include a cartridge base collarhaving cartridge base threadsthat receive and mate with cartridge chamber threads. Flavor adjustercan adjust the amount of additive that is mixed with base liquid. Drinking spout assemblycan have a valve and a valve retainer. Drinking spout assemblycan include a flip cap that can be configured to selectively cover drinking spout assembly. When assembled with lid assembly, drinking spout assembly, flavor adjuster, and cartridge baseprotrude from lid base. Additive cartridgemay additionally include a cartridge chamber inlet (not shown) through which the base liquid disposed within internal spacecan be drawn into by suction.

Closureis configured to move from a closed position () in which closurecovers the additive cartridge receiving space, and an open position () in which an additive cartridge receiving spaceis not covered. To provide this action of closure, as well as a pivoting action of handle, lid assemblycan include a hinge formed by a hinge pinand components of closure, lid base, and handle. For example, closurecan include the hinge component of a first knucklehaving a first pin slot. Lid basecan include hinge components of first postand second post. First postand second postcan each provide a knuckle for housing pin. First postcan have a second knuckleand second postcan have a third knuckle. Second knucklecan have a second pin slotand third knucklecan have a third pin slot. Handlecan include hinge components of a fourth knucklehaving a fourth pin slot (not shown) and a fifth knucklehaving a fifth pin slot. In an assembled condition, the knuckles and pin slots can be aligned such that hinge pincan extend through all of the pin slots enabling closureand handleto pivot about hinge pin. A hinge springcan bias closureto the open position. As shown in, handlecan include a first locking tabextending from fifth knuckleand a second locking tabextending from fourth knuckle. Additionally, handlecan include a third locking taband a fourth locking tab (not shown).shows third locking tabon an interior surface of handle.

Closurecan be configured to accommodate an upper portion of the additive cartridgewhen closureis in the closed position. Closurecan be configured to further accommodate a drinking spout assemblyconnected to additive cartridgeand extending outwardly away from lid baseand internal space. To make these accommodations, closuremay have a domed portion. Additionally, closuremay have a shorter side where first knuckleis located and a longer side opposite first knuckle. First postand second postcan extend away from lid base wallto an elevation corresponding to the longer side of closure. Together, closureand base enclose lid base openingwhen closureis in the closed position. The disparity in length between the shorter side and longer side of closureenables the longer side of closureto clear components extending outwardly from lid base wall. In other words, the longer side of closuremoves in an arcuate path that can clear components of cartridge chamber, as well as upper components of additive cartridge. A low profile of lid baseadjacent the longer side of closure(in a closed position) avoids obstructing access to lid base opening. Accordingly, additive cartridgecan be easily inserted and removed when closureis in the open position. Furthermore, a drinking spout assemblycan also be easily connected and disconnected when closureis in the open position. Closurecan include a first tab slotand a second tab slot. First tab slotmay be configured to receive third locking taband second tab slotmay be configured to receive the fourth locking tab (not shown).

In addition to the disparity in length between the shorter side and the longer side of closure, the position of the hinge on an outermost edge of enclosing wallhelps optimize the available space within lid baseand closurefor cartridge chamber, additive cartridge, and drinking spout assemblyto fit within lid base. The dimensions of lid base can be kept small enough for a user's hand to grip components of lid assemblywhile still accommodating cartridge chamber, additive cartridge, and drinking spout assemblywithin lid baseand closurewhen closureis in the closed position.

Closurecan comprise a shoulderdisposed beneath domed portion. Shouldercan protrude outwardly beneath domed portion. Domed portionand shouldercan be shaped such that handleencircles domed portionand rests on shoulderin the closed position. In some embodiments, for example, as shown in, handlecan comprise a ring shape that encircles domed portion. In other embodiments, handlemay comprise a u-shape or c-shape wrapping partially around domed portion.

Closure can include a skirtextending below both domed portionand shoulder. An outer portion of skirtcan protrude outwardly from shoulder. A latch protrusioncan extend from an edge/rim of skirtand is configured to be latched by the latching mechanism. The outer portion of skirttapers in height from latch protrusiontoward hinge. Handlecan have an inner surface flush with an outer surface of domed portionin the closed position. Shouldercan provide a support for resting handlein a locked position, discussed in more detail below, in which handlelies against shoulder. Additionally, in the locked position, first tab slotcan mate with third locking taband second tab slotcan mate with the fourth locking tab (not shown) to hold handledown onto closure. The contour of the interior surface of skirtcan provide more space inside closurefor drinking spout assemblyto fit within closurein the closed position. In other words, the bulging shape of skirtprovides additional space within closurenear its latch protrusion.

The latching mechanism can be configured to retain latch protrusionextending from skirtof closure. The latching mechanism can include a latch ring, a push plateand a latch loop. Latch ringcan be substantially annular. Latch ringcan have a size and shape corresponding to the annular channel formed within lid base. When assembled, latch ringcan nest within the annular channel. Latch ringcan include a substantially u-shaped bodyhaving a first u-shaped body end and a second u-shaped body end. A first armcan extend from the first u-shaped body end. A second armcan extend from the second u-shaped body end. Latch ringcan include a push plateconnecting the first u-shaped body arm to the second u-shaped body arm. Push platecan be substantially flat. Push platecan be substantially square shaped. In some embodiments, push platemay differently shaped. For example, push platemay be rectangular. In some embodiments, push platecan be substantially curved rather than substantially flat. Push platecan have a top endand a bottom end. Push platecan have a folded extensioncentered at top end.

Latch ringcan include latch loop. Latch loopcan latch closurein the closed position. Latch loopcan include a substantially c-shaped stripextending from a first strip end to a second strip end. U-shaped bodymay include a substantially flat portionat a bottom of the u-shaped bodyhalfway between the first u-shaped body end and the second u-shaped body end. The substantially flat portionmay extend from a first point to a second point. The first strip end can be integrally connected to u-shaped bodyat the first point. The second strip end can be integrally connected to u-shaped bodyat the second point. Together, c-shaped stripand the substantially flat portioncan form a substantially oval shape. When in the closed position, and push buttonis in a resting position, latch protrusionlatches onto c-shaped strip. First armcan include a spring retainerconfigured to hold a spring in place to bias latch ringback toward base plate. Second armcan also include a spring retainer configured to hold a spring in place to bias latch ringback toward base plate.

show lid assemblybeing held in a user's hand. In, the user is not pressing push button. In, the user is pressing push button. Latching mechanism can be movable between the latched position (), in which the latching mechanism retains closurein the closed position, and the release position (), in which closureis free to move to the open position. As shown in, in the resting position, push buttonallows c-shaped stripto stay in a latched position where c-shaped stripis closer toward base plate. As shown by circle, in the resting position, push plateis spaced from latch ring cover. As shown in, in the pushed position, push buttonmoves the latching mechanism to the release position where c-shaped stripis closer toward the user's thumb (farther away from base plate). As shown by circle, in the pushed position, push plateabuts latch ring cover. Push buttoncan be biased in the resting position such that push buttondoes not apply pressure to push plate.

The shape, size, and arrangement of the latching mechanism, push button, and push plateon the hinge side of lid basefrees space where the longer side meets lid base. In this way, the longer side of closurehas more room to clear cartridge chamber, additive cartridge, and drinking spout assemblywhen opening and closing.

The placement of push buttonat the hinge side of lid assemblyadvantageously prevents push buttonand associated components from interfering with latching components and from interfering with the space used to insert and remove additive cartridge. However, it is understood that in some embodiments the latching mechanism can be reconfigured, and push buttoncan be located on the side of base plateopposite the hinge. The thickness (perpendicular to both the height and width) of base plateand part of enclosing wall, excluding first postand second post, are thinner than first postand second postsuch that space within enclosing wallis optimized to provide room for additive cartridgeand drinking spout assemblycomponents.

Handlecan be configured to selectively pivot between two positions: a locked position () and an unlocked position (). In the locked position, handlecan wrap around domed portionof closureand can rest upon shoulderwhen closureis in the closed position. In the unlocked position, handlecan be pivoted about the hinge to an unlocked position in which handleextends outwardly away from lid base.show closurein the open position with handlein the unlocked position. It is understood that handlecan independently move to the unlocked position while closureis still in the closed position. In such a situation, handleno longer wraps around domed portionand the bottle can be carried by handleand/or can be hung on a hook.

In the locked position, handlecan prevent the latching mechanism from moving to the release position. For example,is a partial cross-sectional view (taken along lineof) of latch ringand handlein the locked position, according to an embodiment. In this view, a lateral side of handleand latch ring, as well as folded extension, are in flat view to show their relationship to other components. As shown in, in the locked position, second locking tababuts top endof push plate. Though not shown, it is understood that first locking tabsimilarly abuts top endof push platein the locked position. Folded extensioncan optionally help hold closurein the open position.

When handleis in the locked position and the locking tabs abut push plate, the locking tabs prevent push platefrom moving toward the locking tabs. Accordingly, if push buttonis pressed when handleis in the locked position, the locking tabs can block movement of push plate. When handleis in the unlocked position, first locking taband second locking tabare moved away from push plate(see). In this unlocked position, pressure applied to push buttoncan move latch ring, via push plate, to the release position and closurecan move to the open position.

Lid assemblycan include a latch ring coverhaving a size and shape corresponding to latch ring. Latch ring covercan include a curved inner wall, a curved outer wall, and a flat top wall between the curved inner wall and the curved outer wall. Latch ring covercan operate to guide and support latch ringfor movement and can protect latch ringfrom debris and/or from external objects causing interference with the positioning of latch ring. When assembled, latch ringcan be sandwiched between lid base walland the latch ring cover, such that latch ringcan slide back and forth within an annular space or channel formed between the latch ring cover and lid base wall, for example. In particular, latch ringcan slide toward and away from base plate. Latch ring covercan have a cover cutoutthrough which latch protrusioncan contact and latch onto c-shaped stripwhen push buttonis in the resting position.

A chamber-straw connectorcan connect cartridge chamberto a straw. For example, as shown in, the interior of cartridge chamberhas a tubular shape that tapers toward cartridge chamber inlet. Chamber-straw connectorcan be formed by an elongate body comprising a longitudinal axis. Chamber-straw connectorcan include a chamber-straw connector passageextending along its longitudinal axis. Chamber-straw connectorcan include a chamber connection portionand a straw connection portionopposite chamber connection portion. When assembled, chamber connection portioncan be disposed within the cartridge chamber and straw connection portioncan be disposed outside the cartridge chamber. Chamber connection portionmay include an annular flangethat retains chamber connection portionwithin cartridge chamber. In other words, annular flangecan prevent chamber connection portionfrom slipping out of cartridge chamber.

Lid assembly can include a strawconfigured to be received within chamber-straw connector passagesuch that a fluid pathway extends continuously through strawand additive cartridge. When suction is applied to lid base opening(e.g., through drinking spout assembly), base liquid can be drawn through strawinto additive cartridgewhere the base fluid can mix with an additive and then the mixture of the base liquid and additive can flow out of lid base opening(e.g., through drinking spout assembly). A straw bootcan fit on an end of strawto provide a soft end on straw.

A padof soft non-slip material can be attached to the bottom end of drinking container. Padcan prevent drinking containerfrom scratching surfaces on which drinking containeris set down. Padcan also prevent drinking containerfrom slipping when set down.

In some embodiments, lid assemblycan include a gasket or O-ring sealfor creating a seal between lid base and drinking containerwhen lid base is connected to drinking container.

While various embodiments of the invention have been described, the description is intended to be exemplary, rather than limiting, and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
