FIELD OF THE INVENTION
- Top of Page
The present invention generally relates to a compound sports water bottle, in which re-filtering of water is carried out to provide concern-free water drinking, and is particularly applicable to water container that stores therein drinking water, such as a regular water kettle, a sports water flask, or the likes.
(b) DESCRIPTION OF THE PRIOR ART
Water takes approximately 70% by weight of human body. A person can still survive without taking food for 2-3 days, but he cannot live without drinking water for just one day. Water is of significant importance to human body. Water is even more important when a person takes physical exercises. Thus, whatever exercises a person is taking, he must be provided with a container that supplements water for him.
Commonly seen water containers include PET (Poly Ethylene Terephthalate) bottles that contain therein mineral water or other soft drinks, regular water kettles, and sports water flasks that are specifically designed for sports use. No matter whatever type a water container is, the container comprises a container body for receiving and storing a liquid and also has an opening or mouth that is coupled to a cap to allow water to be filled in the container body for easy carrying and for supplemental of water to the user at any time and any site.
However, the conventional water container, such as PET bottles and water kettles, have a single function of receiving and storing liquid or water therein and do not provide other functions. In view of this, the present invention aims to provide a compound sports water bottle in which re-filtering of water is carried out in order to provide concern-free water drinking.

OF THE INVENTION
An objective of the present invention is to provide a compound sports water bottle in which re-filtering of water is carried out in order to provide concern-free water drinking.
To achieve the above objective, the present invention provides a compound sports water bottle that comprises a bottle body having an opening forming a fastening section and a bottle cover that comprises a counterpart fastening section. The bottle cover comprises a tube that extends through the cover. The tube has an end over which a slidable cover is movably fit, whereby the movement of the slidable cover forms an outlet opening. The tube has an opposite end to which a filter element forming a passage is coupled. As such, liquid contained in the bottle body is allowed to be filtered by the filter element before flowing out of the bottle through the passage, so that the liquid can be drunk in a concern-free manner.
In the compound sports water bottle described above, the counterpart fastening section of the bottle cover further comprises a sealing ring.
In the compound sports water bottle described above, the filter element comprise a filter of one of active charcoal, resin, far infrared, energy stone, and ceramics.
In the compound sports water bottle described above, the filter element that is coupled to the bottle cover comprises a fitting section that has a diameter smaller than the bottle cover, whereby with a combination of the fitting section with a filter sponge and a filter screen, the active charcoal is securely held together.
In the compound sports water bottle described above, the opening of the bottle body forms a stop rim, which prevents the outlet cap from separating from the opening.
Compared to the existing technology the present invention shows the following advantages:
(1) The bottle cover has an outlet opening inside which a filter element is mounted, whereby in drinking the liquid contained in the bottle, the liquid is first filtered by the filter element before being drunk, so as to realize concern-free drinking.
(2) Besides containing and storing water, the water bottle may also provide a filtering function.
(3) With the arrangement of the filter element that is simple in structure and low in cost, the water bottle is provided with an enhanced competition power in the market.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

OF THE PREFERRED EMBODIMENTS
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
The present invention will be described in detail with reference to a preferred embodiment thereof.
Referring to FIGS. 1 and 2, the present invention provides a compound sports water bottle 1, which comprises a bottle body 11, a bottle cover 12, an outlet cap 13, and a filter element 14. The bottle body 11 is a container that forms therein a receiving space or chamber. The container has an opening or mouth forming a thread to serve as a fastening section 111. The fastening section 111 has a top end forming a horizontal stop rim 112.
Also referring to FIG. 5, the bottle cover 12 has a lower portion that forms a counterpart fastening section 121 corresponding to and engageable with the fastening section 111 of the bottle body 11. The bottle cover 12 is provided centrally with a tube 122 that extends through the bottle cover 12. A central post 123 is formed inside the tube 122, and a stepped section 124 is formed around an outer circumference of the tube 122. The stepped section 124 receives an O-ring 125 fit thereto. The tube 122 comprises a slidable cover 126 that forms therein a reversed stepped section 127 and also has a top forming centrally a through hole.
The outlet cap 13 comprises a cap body that is selectively fit over the slidable cover 126. Projecting from one side of the cap body is a connection section 131 that is connected to a retention ring 132 defining a central bore.
