referring to fig1 and 5 , a bottle ( shown generally as 100 ) is shown having a valve 102 and a mask 104 . the mask 104 has a cut out portion 112 that fits over a user &# 39 ; s nose ( not shown ) when used to inhale oxygen . the bottle 100 consists of a water bottle 106 with an air bottle 110 partially disposed within water bottle 106 and contained within a sleeve 108 . sleeve 108 may completely surround both water bottle 106 and air bottle 110 or may only partially surround the bottles . sleeve 108 helps hold air bottle 110 in place and gives extra structural support to bottle 100 . sleeve 108 is made of a suitable insulative material as is known in the art to provide insulative qualities to bottle 100 to help keep water cool . mask 104 also functions as a protective cover for bottle 100 and conceals both water bottle cap 206 and oxygen nozzle 204 . oxygen nozzle 204 has a valve assembly 202 that allows oxygen to flow when valve 102 is fitted into nozzle 204 and depressed . in use , mask 104 is removed form bottle 100 and valve 102 is placed against nozzle 204 . this places mask 104 in a generally horizontal orientation allowing a user to comfortably place mask 104 against face ( not shown ) and by pressing down on valve 102 oxygen is released allowing user to inhale oxygen . the oxygen stops flowing when valve 102 is released . any appropriate valve structure will work as is know in the art . a biasing spring ( not shown ) may be used to provide a normally closed valve function . mask 104 may be removed from nozzle 204 and used to cover bottle 100 for later use . mask 104 may remain in place while a user removes water bottle cap 206 and drinks from the water bottle 106 or the user may temporarily remove mask 104 while drinking . oxygen bottle 110 is ideally pressurized at a level that remains safe in the unlikely event of structural failure . although many materials would be acceptable , pet ( polyethylene terephthalate ) plastics are generally best for this application because pet plastics are clear , tough and are a good barrier to gas and moisture . pet plastics also have very good heat characteristics . a typical pet bottle is designed to withstand pressure of up to 150 psi . the present invention uses oxygen at a pressure well below 150 psi providing a very reliable safety margin . a typical 2 liter carbonated soft drink is pressurized at approximately 35 psi at 45 degrees f . fig3 illustrates another embodiment of the present invention . in this embodiment a bottle 300 also contains a water bottle 304 and an oxygen bottle 306 , however the inner bottles are linearly arranged in a vertical orientation . in this embodiment , oxygen breathing mask 314 forms a natural base for bottle 300 . an upper portion 350 of bottle 300 is a water bottle 302 which holds water 304 for drinking . water 304 may be purified , spring , fortified with trace minerals , distilled , etc . as is common in the art . in other embodiments , other liquids such as soda , tea , milk or other liquid beverages may be contained by upper portion 350 . a lower portion 360 of bottle 300 contains an oxygen bottle 306 which contains pressurized oxygen 324 suitable for breathing . water bottle 302 has a conventional cap 326 used to access water 304 . again , pet plastic is used in this embodiment . a sleeve 320 extends below upper portion 350 of bottle 300 and forms a hollow space which holds oxygen bottle 306 . mask portion 314 has a corresponding sleeve 318 that press fits into upper sleeve 320 to provide a friction fit while allowing movement between the two sleeves . like the previous embodiment , mask 314 has a nose cutout portion 316 that allows a user to comfortably press mask 314 against the face ( not shown ) and breath in oxygen . mask 314 is connected to oxygen bottle 306 by a valve 310 . valve 310 includes a central portion 322 that is connected to mask 314 . a spring 312 biases center portion to close against a seal 308 such as an o - ring or other sealing means as is known in the art . in use , a user ensures that cap 326 is secure and turns bottle 300 over and presses mask 314 gently allowing oxygen 324 to enter mask 314 . as the user stops pressing mask 314 against water bottle 302 , oxygen 324 stops flowing and the user is free to drink conventionally from bottle 300 . in another embodiment , mask 314 includes a hinged sanitary cover ( not shown ) that covers a bottom section of mask 314 so that foreign matter will not contaminate mask 314 when bottle 300 is set down on an unclean surface . in use , a user would simply flip open the hinged cover ( not shown ) when breathing oxygen and then close it before setting it back down on a surface . mask 314 may be made of any suitable material such as rubber or flexible plastic . referring now to fig4 , a bottle 400 is shown having two oxygen spheres 412 centrally disposed within a water bottle 414 . oxygen spheres 412 are made from any suitable material but again pet plastic is particularly well suited for this application . although two spheres 412 are shown , other embodiments such as one , three spheres or even a radial arrangement of cylindrical oxygen cells ( not shown ) would be possible . bottle 400 has a mask 402 for breathing oxygen . a user places mouth and nose against mask 402 and presses to start the flow of oxygen . the oxygen is controlled using a valve 422 that is biased with a spring 406 . a stepped plunger 408 is provided to control the oxygen flow as it enters mask 402 . any suitable valve structure such as a needle valve or ball valve as is well known in the art could be used to control the flow of oxygen . valve 422 is enclosed by a pet plastic cone 410 and includes threads 424 which fit into threaded cap 404 . water bottle 414 includes a water outlet 420 secured with a threaded cap 418 . although the instant invention has been described in relation to particular embodiments thereof , many other variations and modifications and other uses will become apparent to those skilled in the art .
a bottle contains at least one oxygen chamber allowing a user to breathe pure oxygen by placing their mouth and nose in a facemask contoured to fit the users face . the bottle also holds water so the user can drink clean pure water as well . the oxygen is pressurized allowing more oxygen to be stored in the chambers and to aid the user in getting the oxygen into his or her lungs . the present invention allows a user to drink water and breathe pure oxygen in a safe and convenient manner .
