Water bottle with selectively accessible compartment for storing and mixing powders

Abstract

A bottle provides for separately storing a powder and a liquid and selectively mixing the powder into the liquid. The bottle includes a main body having a bottom wall with a transfer passage, a perimeter wall attached to the bottom wall, and a main-body cap sealingly attachable to the perimeter wall. A main-body projection is sealingly attached to the bottom wall and forms a conduit with an outlet. A sealing body in the conduit has resting and activated positions, is biased toward the resting position, and is displaceable to unblock the outlet. A secondary body is sealingly attachable to the main body and has a bottom wall with an access passage and a secondary-body projection containing an activation body. The activation body is configured to displace the sealing plug when the activation body is in an activated position.

I claim: 
     
         1 . A bottle for separately storing a powder and a liquid and for selectively mixing the powder into the liquid, the bottle comprising:
 a main body having:
 a main-body bottom wall having a transfer passage extending therethrough; 
 a main-body perimeter wall sealingly attached to the main-body bottom wall and forming a main-body upper opening; 
 a main-body cap sealingly attachable to the main-body perimeter wall to seal the main-body upper opening,
 wherein the main-body bottom wall, the main-body perimeter wall, and the main-body cap together enclose a main-body volume, and 
 wherein the transfer passage is in fluid communication from the main-body volume outside of the main body; 
 
 a main-body projection sealingly attached to the main-body bottom wall, the main-body projection including:
 a main-body-projection perimeter wall surrounding the transfer passage and sealingly attached to the main-body bottom wall, the main-body-projection perimeter wall forming a main-body projection conduit, wherein the main-body-projection perimeter wall comprises an outlet linking an interior space of the main-body projection conduit to the main-body volume; 
 a main-body-projection cap sealingly attachable to the main-body-projection perimeter wall; 
 a sealing body comprising a sealing plug disposed for movement with respect to the outlet, the sealing plug being biased to a closed position blocking the outlet and being displaceable to an open position un-blocking the outlet; 
 
   a secondary body configured to be sealingly attachable to the main body to engage a lower portion of the main body, the secondary body having:
 a secondary-body bottom wall having an access passage extending therethrough; 
 a secondary-body perimeter wall sealingly attached to the secondary-body bottom wall and forming a secondary-body upper opening; and 
 a secondary-body projection sealingly attached to the secondary-body bottom wall, the secondary-body projection including:
 a secondary-body-projection perimeter wall surrounding the access passage and sealingly attached to the secondary-body bottom wall, the secondary-body-projection perimeter wall forming a secondary-body access conduit; and 
 an activation body slidably disposed in the secondary-body access conduit and having a resting position and an activated position, the activation body being biased toward the resting position from the activated position,
 the activation body having an activation projection extending therefrom toward the main body, the activation projection being configured to displace the sealing plug into the open position when activation body is in the activated position. 
 
 
   
     
     
         2 . The bottle of  claim 1 , wherein the main-body cap is configured to threadedly engage the main-body perimeter wall. 
     
     
         3 . The bottle of  claim 1 , further comprising a lower skirt extending downwardly and forming the lower portion of the main body below the main-body bottom wall, the lower skirt forming a main-body recess sealingly engageable with the secondary body, with the main-body recess accepting at least a portion of a height of the secondary body when the secondary body is engaged with the lower skirt. 
     
     
         4 . The bottle of  claim 3 , wherein the main-body recess accepts at least 90 percent of the height of the secondary body when the secondary body is engaged with the lower skirt.
