Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates a drink through spout cap that can be used with common beverage bottles.

2. Description of Related Art

Caps for fitting on threaded beverage bottles are known. U.S. Pat. No. 6,112,926, issued to the inventor of this application, describes a non-closeable threaded drink through spout cap for common beverage bottles. A cap having a threaded interior is screwed onto the threads of the upper portion of the beverage bottle. A slotted aperture enables liquid to flow through the cap at a decreased volume and rate. The cap makes drinking from a twist top beverage bottle easier for toddlers and/or people who have difficulty drinking from common beverage bottles or who simply prefer a more regulated flow and contoured spot.

Recently, there have been green initiative efforts to conserve the amount of plastic used to make caps for threaded beverage bottles. In this effort, some manufactures of beverage bottles have reduced the cap size and the corresponding number of threads of the cap and the bottle. Other manufactures of beverage bottles continue to manufacture caps and bottles with conventional sizes. Accordingly, a cap having a threaded interior will not fit on all types of currently manufactured beverage bottles.

It is desirable to provide a drink through spout cap providing a leak proof seal that can be used with common beverage bottles.

SUMMARY OF THE INVENTION

The present invention relates to a drink through spout cap system including a drink through spout cap and a coupler. The coupler is removably or permanently coupled to a base housing of the cap. The inner wall of the base housing is substantially smooth and does not engage threads of a beverage bottle after the beverage bottle is received within the base housing. Accordingly, an appropriately sized spout cap can be used with a selected size of a common beverage bottle, regardless of the type of threads of the beverage bottle. The coupler is received in the beverage bottle for coupling the beverage bottle to the base housing of the cap. The coupler includes an aperture therein for allowing a beverage in the beverage bottle to flow through the aperture to the spout.

The coupler can be formed of a plastic, thermoplastic rubber (TPR), silicone, fabric, or thermoplastic material. The coupler can be permanently attached to the base housing of the cap by injection molding by injection molding or via snapping into place using a locking mechanism, notch, ring, or other method.

In one embodiment, the coupler has a tapered shape. Alternatively, the coupler can include a plurality of radially extending ridges of the same or different diameters. The ridge having a largest diameter contacts an inner wall of the bottle below the neck to allow the coupler to be expeditiously inserted into a bottle and provide a leak proof seal.

The invention will be more fully described by reference to the following drawings.

Slopes of sides 17 and 18 can be selected to be dental friendly and provide comfort to a mouth of a user. In one embodiment, side 17 can have a steeper slope and side 18 can have a shallower slope with spout member aperture 15 offset with respect to a center of base housing 14 toward side 17. Side 17, side 18 and opposed sidewalls 19 form an asymmetrical pyramid having spout member aperture 15 at the truncation of the pyramid.

Base housing 14 can be cylindrical with a diameter D1 slightly larger than diameter D2 of opening 21 of beverage bottle 20. Beverage bottle 20 can be a common beverage bottle in any size, shape and configuration. Suitable common beverage bottles are known beverage bottles for containing water, soda, juice, sports drinks, and the like. Base housing 14 can have a size, shape and configuration to receive neck 22 of beverage bottle 20. Diameter D1 of base housing 14 can be appropriately sized to be used with an intended size of beverage bottle 20. For example, diameter D1 of base housing 14 can be in the range of about 18 mm to about 38 mm for receiving beverage bottle 20 having diameter D2 of opening 21 in the range of about 17 mm to about 37 mm.

Opening 21 extends from neck 22. Neck 22 includes inner wall 23 and outer wall 24. Typically, inner wall 23 of beverage bottle 20 is smooth and outer wall 24 of beverage bottle 20 includes threads 25. The number of threads 25 can vary. The thickness, spacing and trajectory of threads are variable. Inner wall 26 of base housing 14 is substantially smooth and does not engage threads 25 of beverage bottle 20, if they are present, after beverage bottle 20 is received within base housing 14. Base housing 14 and coupler 30 can be reusable and can be attached to various beverage bottles 20.

Gasket 27 can be positioned at top portion 28 of base housing 14 adjacent to spout member 12. Gasket 27 provides a leak proof seal with top portion 31 of coupler 30 after beverage bottle 20 is received within base housing 14.

Coupler 30 is positioned within base housing 14. Coupler 30 can be removably coupled to base housing 14. Alternatively, coupler 30 can be permanently coupled to base housing 14. Coupler 30 is received within opening 21 of beverage bottle 20 for coupling base housing 14 to beverage bottle 20. Coupler 30 includes aperture 32 for allowing liquid to flow through coupler 30 to spout member aperture 15 of spout member 12.

Coupler 30 can be formed of any suitable material including but not limited to a plastic, flexible plastic, silicone, fabric, thermoplastic rubber (TPR) or thermoplastic material. Suitable materials for coupler 30 include thermoplastic rubber (TPR). Thermoplastic rubber (TPR) comprises materials with both thermoplastic and elastomeric properties. Suitable materials include copolymers or a mix of polymers, such as a plastic, and a rubber. Inner wall 26 of base housing 14 and gasket 27 can also be formed of a plastic, flexible plastic, silicone, fabric, thermoplastic rubber (TPR) or thermoplastic material, as shown in FIG. 6. Inner wall 23 of base housing 14 can engage threads 25 in order to facilitate additional grip and seal. Gasket 27 can be integral with coupler 30.

In one embodiment, coupler 30 has a tapered shape, as shown in FIG. 2. Diameter D3 of bottom portion 33 of coupler 30 is smaller than diameter D4 of top portion 31 of coupler 30. Diameter D4 of top portion 31 can be substantially the same size as diameter D1 of base housing 14 for providing a leak-proof seal between coupler 30 and base housing 14 when the flexible coupler 30 is removably inserted into base housing 14 or permanently attached to base housing 14.

In an alternate embodiment, coupler 30 comprises a plurality of ridges 40a-40n extending from coupler base 42, as shown in FIG. 4 and FIG. 5A. Coupler base 42 can be cylindrical and ridges 40a-40n can have the same or different diameters. Ridges 40a-40n radially extend from coupler base 42. In one embodiment, ridge 40a has the largest diameter for contacting inner wall 23 of neck 22, as shown in FIG. 5B. Alternatively, ridge 40a can contact inner wall 41 of bottle 20 at or below neck 22. Ridge 40a can be used to aid in anchoring coupler 30 to bottle 20. Ridges 40b-40n can have decreasing diameters. Coupler base 42 includes top sealing portion 44. Diameter D5 of top sealing portion 44 can be substantially the same size as diameter D1 of base housing 14 for providing a leak-proof seal between coupler 30 and base housing 14. The number of ridges 40a-40n can be selected to provide a desired vacuum seal between coupler 30 to inner wall 23 of neck 22 thereby preventing liquid from leaking around coupler 30 after beverage bottle 20 is received within base housing 14.

Base housing 14 can have a length L1 which is smaller than the length L2 of coupler 30, as shown in FIG. 5A. Base housing 14 can have a length L1 being greater or substantially the same length L2 of coupler 30 in order to cover coupler 30, as shown in FIG. 5B.

Gasket 27 and or inner wall 26 can be injection molded through one or more apertures 29 of base housing 14. Gasket 27 can included flanges 39 formed after injection molding, as shown in FIG. 7. Flanges 39 which extend through apertures 29 shown in FIG. 6. Coupler 30 can be injected molded into base housing 14 such that gasket 27, inner wall 26 of base housing 14 and coupler 30 are integral with base housing 14 to for a one-piece construction, as shown in FIG. 8.

Coupler 30 can include check valve 34 within aperture 32 for controlling flow within coupler 30, as shown in FIG. 9. Spout cap 11 can include ridges 50 on outer surface 51.

During operation, a cap (not shown) of beverage bottle 20 is removed. Coupler 30 is inserted into opening 21 of beverage bottle 20. The flexible material of coupler 30 allows coupler 30 to be expeditiously received in opening 21 of bottle 20. Spout cap 11 is received over inserted coupler 30 until gasket 27 of base housing 14 contacts top portion 31 of coupler 30 to provide a leak proof seal between base housing 14 and coupler 30. In an alternate embodiment, coupler 30 and base housing 14 are integral to one another. In this embodiment, after a cap of beverage bottle 20 is removed, coupler 30 is inserted into opening 21 of beverage bottle 20 for coupling spout cap 11 to beverage bottle 20. The spout cap system can be used with a common beverage bottle to allow the user to drink from a contoured spout rather than directly the opening of the beverage bottle.
