Description

BACKGROUND OF THE INVENTION

This invention generally relates to a beverage container. More particularly this invention relates to a beverage container including features for storing separate component parts of a mixture prior to consumption.

Typically, soft drinks, sports drinks, and other drinks are stored within a sealed beverage container prior to purchase. The duration between the time that the beverage is placed within the container and actually consumed can be significant. Therefore, many beverages include a sell-by date to insure that the beverage is sold within a desired time to ensure a desired level of freshness.

Commonly beverages are a mixture of several ingredients dissolved within a liquid such as water. The mixture of ingredients is typically performed at a bottling or other production facility just prior to being placed within a sealed beverage container. A sport drink typically includes ingredients that are intended to replace nutrients lost during robust physical activity. In some instances, those ingredients can begin to lose potency once mixed. Disadvantageously, there can be a significant period between the time a beverage mixed and bottled and consumption.

Accordingly, it is desirable to develop and design a beverage container that can store a beverage for long periods, while still providing the desired just mixed freshness upon consumption.

SUMMARY OF THE INVENTION

This invention is a beverage container including a lid assembly having a chamber for storing and subsequently releasing a component of a mixture into a liquid stored within the container.

The example beverage container includes a lid assembly attached to a container containing a liquid. The lid assembly includes an upper housing attached to a lower housing. The upper housing includes a button movable between a locked position and a released position. The upper housing also includes a spout that provides access to the contents of the container.

A disk snaps into a snap groove within the lower housing and includes the chamber for storing one component of the mixture separate from liquid within the container. The chamber is initially placed in a storage position that is not aligned with the inlet. In this position, the contents of the chamber are isolated from the container. When it is desired to mix the component stored within the chamber with the liquid within the container, the button is depressed to permit rotation of the upper housing and the disk. Rotation of the upper housing aligns the chamber with an inlet in the lower housing to the container. The contents of the chamber are then free to fall into and mix with the contents of the container.

Accordingly, the beverage container of this invention provides for the separation of components such that a beverage may be stored for long periods, while still providing the desired just mixed freshness upon consumption.

These and other features of the present invention can be best understood from the following specification and drawings, the following of which is a brief description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, an example beverage container 10 is shown that provides for storing of at least two mixable substances separately prior to mixing by a consumer of a beverage. The beverage container 10 includes a container 12 and a lid assembly 14 for holding and storing a liquid within the container 12. The lid assembly 14 includes a lower housing 18 attachable to the container 12 and an upper housing 20 attached to the lower housing 18. The upper housing 20 includes a button 21 that is movable between a locked position and a released position. In the released position, the upper housing 20 is rotatable relative to the lower housing 18. The upper housing 20 includes a spout 15 that provides access to the contents of the container 12. The lid assembly 14 stores and subsequently releases into the container 12 a component part for mixing with liquid stored within the container.

The lid assembly 14 includes a disk 22 having a chamber 16. The chamber 16 provides for the storage of one of the mixable substances. The disk 22 snaps into a snap groove 24 within the lower housing 18 and is rotatable relative to the lower housing 18. The upper housing 20 includes an outlet tube 64 that assembles into the lower housing 18 by way of a snap fit through an outlet opening 28. The snap fit of the outlet tube 64 provides for rotation of the upper housing 20 relative to the lower housing 18. The button 21 assembles into the upper housing 20 and is held in the locked position by a biasing arm 60.

Referring to FIGS. 3 and 4, the lower housing 18 includes an annular guide groove 32. The guide groove 32 includes a locking grove 34 that juts radially outward normal to the guide groove 32. The disk 22 includes a guide arm 42 that guides within the guide groove 32. The disk 22 also includes a locking tab 44 that extends from a peripheral edge 46 of the disk 22. The locking tab 44 rotates with the disk 22 and engages a ramped surface 36 of the lower housing 18 upon reaching an aligned position. In the aligned position, the chamber 16 is aligned with an inlet 26. The locking tab 44 bends upwardly responsive to engaging the ramped surface 36 until dropping into retention groove 38. The locking tab 44 locks the disk 22 into the aligned position with the chamber 16 aligned with the inlet 26.

Referring now also to FIG. 7, the button 21 includes a guide member 58 that extends into the guide groove 32. The guide member 58 is disposed within the locking groove 34 when in a locked position to prevent rotation of the upper housing 20. Depressing the button 21 moves the guide member 58 radially inward and into the guide groove 32. The upper housing 20 is then free to rotate. The guide arm 42 of the disk 22 includes a slot 45 into which the guide member 58 is received. Accordingly, movement of the upper housing 20 is transferred to the disk 22 through the button 21. Depressing the button 21 frees the guide member from the locking groove 34, and allows rotation of the upper housing 20 and disk 22 relative to the lower housing 18.

Referring now also to FIG. 5, the disk 22 includes a seal 48 surrounding the chamber 16. The seal 48 is disposed between the disk 22 and a surface 30 of the lower housing 18. The snap groove 24 holds the disk 22 in place such that pressure is applied to the seal 48 to prevent migration of material within the chamber 16. The seal 48 slides along the surface 30 during rotation of the disk 22 and maintains the desired seal.

The chamber 16 is a spherical cavity having the opening 17. The size of the chamber 16 is determined to provide a desired storage capacity required for a desired mixture. The volume of the chamber 16 substantially coincides with the amount of material required to provide the desired concentration of the final mixed beverage. The volume of the chamber 16 is not necessarily equal to the quantity of component for mixing. As appreciated, a larger chamber 16 can provide storage for lesser amounts of component for mixing as is desired. Further, although a semispherical shape is shown in the example, other shapes that provide the desired storage capacity are also within the contemplation of this invention. Further, multiple chambers 16 (FIG. 4B) may be utilized to store different component mixtures or increase the capacity for storing one component mixture.

Referring now also to FIG. 6, an underside of the spout 15 is shown and includes a first annular seal 52 and a second elongated oval shaped seal 54. The spout 15 slides within a slot 68 (FIG. 2) of the upper housing 20. The outlet tube 64 includes a first end in communication with the contents of the container 12 and a second end terminating at the spout 15. The spout 15 seals against spilling of the contents in both the open and closed positions. In the closed positions, the outlet tube 64 is covered by the spout 15 and the seal 54. In the open position, an opening 50 of the spout 15 is aligned with the outlet tube 64 to allow consumption of the contents of the container. The spout 56 includes a mouthpiece portion 56 adapted to direct the contents of the container 12.

The spout 15 includes a ridge portion 55 that corresponds to a ridge 25 about a circumference of the upper housing 20. When the spout 15 is in a closed position the ridge 55 conforms to the ridge 25 to provide a desired continuous and desirable appearance.

Referring to FIG. 8, the chamber 16 stores a component such as a powder or a liquid. As appreciated, the composition of the powder or liquid can include mixtures to enhance taste or add valuable nutrients. The container 12 stores a liquid such as for example water. Further, other liquids may also be stored that correspond with the component stored within the chamber 16. The specific contents of the chamber 16 and the container 12 are combined to provide a desired mixture that benefits both nutritionally and preferentially from being consumed upon mixing.

In use, the container is filled with a liquid and the chamber 16 filled with a powder or other mixture for mixing with the liquid. Other mixtures can include liquids, gels, crystals or forms as known in the art. The chamber 16 is placed in the storage position. The storage position comprises a position that is not aligned with the inlet 26. In this position, the contents of the chamber 16 are isolated from liquid within the container 12. The beverage container 10 is shipped to a destination for purchase by a consumer.

A consumer can drink from the container by sliding the spout 15 toward a center position to align the opening 50 with the outlet tube 64. The contents of the chamber 16 need not be dispensed to allow access to liquid within the container 12. As appreciated, a consumer may prefer to drink the liquid within the container 12. When it is desired to mix the component stored within the chamber 16 with the liquid within the container 12, the button 21 is depressed. Depressing the button 21 moves the guide member 58 from the locking groove 34 (FIG. 3) to permit rotation of the upper housing 20. The button 21 includes a biasing arm 60 that engages a ramped surface 70 of the upper housing 20. The corresponding engagement biases the button 21 radially outward such that release of the button 21 drives the button 21 back toward the locked position.

Rotation of the upper housing 20 results in a concurrent rotation of the disk 22. The guide member 58 rotates to an end 35 of the guide groove 32. Once the guide member 58 is free of the locking groove 34, the button 21 need not be held. As the end 35 is reached, the biasing arm 60 will drive the button 21, and thereby the guide member 58 into the locking groove 34. The end of the guide groove 32 coincides with alignment of the chamber 16 with the inlet 26. The contents of the chamber 16 are then free to fall into the container 12. The contents of the chamber 16 and container are then mixed for consumption. The spout 15 may slide as indicated by arrows to 66 to access the liquid, or to close the container 10 for later consumption.

The beverage container 10 of this invention provides for the isolation and subsequent mixing of two components of a beverage. The components may include many different mixtures such as a sports drink where beneficial nutrients are added to water. Further, other uses are within the contemplation of this invention such for storing and mixing an infant's formula, or adding a component providing a desirable taste or color change for aesthetic reasons. Further, the number of chambers 16 may be increased to add additional components for mixing.

Although a preferred embodiment of this invention has been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied to determine the true scope and content of this invention.
