1. Field of the Invention
The invention relates to a drinking bottle, more particularly to a drinking bottle including a bottle body and a hollow inner body mounted in the bottle body through a bottom cap.
2. Description of the Related Art
U.S. Pat. No. 6,415,264 discloses a thermally-regulated drinking bottle that includes a bottle body having an outer wall portion defining a chamber therein, and an inner wall portion extending from a bottom end of the outer wall portion into the chamber and defining an inner space isolated from the chamber. A plug is fitted sealingly into a bottom open end of the inner wall portion. A coolant can be filled in the inner space in the inner wall portion so as to prolong a chilled temperature of a drinkable liquid in the chamber. Since the inner and outer wall portions are an integral single piece, they cannot be utilized independently.
Therefore, the object of the present invention is to provide a drinking bottle that can overcome the aforesaid drawback associated with the prior art.
Accordingly, a drinking bottle of the present invention comprises: a bottle body defining a chamber therein and having a top connecting portion and a bottom connecting portion that defines a bottom opening of the bottle body; a bottom cap coupled detachably to the bottom connecting portion of the bottle body for covering sealingly and uncovering the bottom opening of the bottle body; a hollow inner body disposed in the chamber of the bottle body, defining an inner space therein, and having a top closed end and a bottom connecting portion that defines a bottom opening of the inner body and that is coupled detachably to the bottom cap; and a sealing member coupled detachably to the bottom connecting portion of the inner body for covering sealingly and uncovering the bottom opening of the inner body.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
Before the present invention is described in greater detail with reference to the accompanying preferred embodiments, it should be noted herein that like elements are denoted by the same reference numerals throughout the disclosure.
In this embodiment, the bottom cap 3 has a circular base wall 31 and a surrounding wall 32 extending axially from a peripheral edge of the base wall 31 and engaging threadedly the bottom connecting portion 26 of the bottle body 2. The bottom cap 3 is formed with an annular wall 34 extending axially from a center of the base wall 31 into the chamber 20 of the bottle body 2 and engaging threadedly the bottom connecting portion 413 of the inner body 4. A sealing O-ring 36 is disposed between and is in sealing contact with the surrounding wall 32 and the bottom connecting portion 26 of the bottle body 2. The sealing member 412 includes a plug 412′ that is fitted sealingly into the bottom connecting portion 413 of the inner body 4.
The drinking bottle further includes a valve-supporting member 50 (see
With the inclusion of the bottom cap 3 and the inner body 4 in the drinking bottle of this invention, the aforesaid drawback can be eliminated.
While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
