## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority under 35 U.S.C. §119(e) to provisional U.S. Patent Application No. 61/313,416, filed on Mar. 12, 2010, the disclosure of which is expressly incorporated by reference herein in its entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is directed generally to a drink bottle and, more particularly, to a reusable drink bottle that includes a number of user-friendly features,
2. Related Art
Typical disposable drink bottles are formed of a clear material, have a typically taller construction with a narrow spout that is closable. Users find this arrangement to be very desirable in that such a shape is usually easily carried and the drink that is contained in the drink bottle can be easily dispensed through the smaller spout and closed for later use. However, typical disposable water bottles cannot be readily reused in that they are not easily cleaned. For example, the smaller spout of such bottles does not allow one to easily and fully clean the inside of the bottle. Additionally, the light weight construction of such disposable bottles does not allow them to be dishwasher safe. In that regard, if disposable bottles are cleaned multiple times, the water bottle material deteriorates to some degree. Finally, such disposal water bottles do not lend themselves to being used in conjunction with a drink that has additional ingredients such as ice. In that regard, the small drink spouts of a typical disposable drink bottle do not allow large pieces of ice or drink powders to be easily put into the water bottle and accordingly users will typically not use such disposable water bottles in that way. In this regard, users of disposable water bottles will use the bottle once and then dispose of it. This causes a great deal of waste in that water bottles will be sent to a landfill or the like. Even, if the user recycles the water bottle there is a certain level of waste and energy needed to turn that water bottle into some sort of recycled product.
SUMMARY OF THE INVENTION
The invention meets the foregoing needs and provides a drink bottle that includes a tall shape and clear construction, together with the ability to be easily cleaned, and/or used with ingredients and that furthermore includes other advantages apparent from the discussion herein.

Finally the drink bottle 100 may include a construction that does not easily trap food.
The drink bottle 100 may also further include a tether 110 to connect the bottle cap 108 in a tethered fashion to the drink bottle 100. In that regard, the tether 110 may be constructed such that it allows the bottle cap 108 to freely spin so that it may be unthreaded or disconnected from the bottle 100 and then can freely hang from the tether along the side of the bottle 100 and not be lost or misplaced. As shown in FIG. 2, the drink bottle 100 may also include a gasket 202 arranged between the upper bottle portion 104 and the lower bottle portion 102. The gasket 202 may be formed of silicone or other similar material that forms a liquid tight seal when the upper bottle portion 104 is arranged and attached to a lower bottle portion 102.
The lower bottle portion 102 includes a sidewall 121, a bottom portion 122, and an upper opening 123. In one embodiment, the lower bottle portion is substantially cylindrical, with the sidewall 121 corresponding to the curved surface of a cylinder and the bottom portion 122 corresponding to a bottom face of a cylinder and the upper opening 123 corresponding to the top face of a cylinder. The sleeve 106, in embodiments where the sleeve is disposed about the lower bottle portion 102, is disposed about the lower bottle portion sidewall 121. In embodiments of the lower bottle portion having threading, the threading may be on an exterior face of the sidewall 121, on an interior face, or both. In one embodiment, the lower bottle portion 102 includes a lower bottle engagement portion 125 adjacent the upper opening 123.
Lower bottle portion 102 may be manufactured using a blow molding process. However, it is contemplated that other types of manufacturing processes may be used. The material of lower bottle portion 102 may be, in one embodiment, an appropriate polymer, such as TritanTM. However, other materials with similar qualities may also be used. Finally, the lower bottle portion 102 may be formed of a transparent, translucent, or opaque material in order to emulate the common disposable water bottle.
The upper bottle portion 104 includes a sidewall 141, a lower opening 143, and the spout 404. The sidewall 141 defines the lower opening 143 and extends therefrom to the spout 404. The sleeve 106, in embodiments where the sleeve is disposed about the upper bottle portion 104, is disposed about the upper bottle portion sidewall 141. In embodiments of the upper bottle portion 104 having threading, the threading may be on an exterior face of the sidewall 141, on an interior face, or both. In one embodiment, the upper bottle portion 104 includes an upper bottle engagement portion 145 adjacent the lower opening 143. The lower bottle engagement portion 125 is removably securable to the upper bottle engagement portion 145.
