Insulated bottle

Abstract

A liquid container system includes an inner bottle that has a base portion with a first diameter. The system also includes an outer bottle that surrounds at least a portion of the inner bottle. The outer bottle includes a mid-portion that has a second diameter, and the second diameter is less than the first diameter. The system further includes a first indent in the inner bottle that, responsive to an applied pressure, decreases the first diameter of the base portion of the inner bottle such that the first diameter is less than or equal to the second diameter.

1 . A liquid container system comprising:
 an inner bottle that has a base portion with a first diameter;   an outer bottle that surrounds at least a portion of the inner bottle, wherein the outer bottle includes a mid-portion that has a second diameter, wherein the second diameter is less than the first diameter; and   a first indent in the inner bottle that, responsive to an applied pressure, decreases the first diameter of the base portion of the inner bottle such that the first diameter is less than or equal to the second diameter, wherein the first indent is positioned entirely within the base portion of the inner bottle.   
     
     
         2 . (canceled) 
     
     
         3 . The system of  claim 1 , further comprising a second indent positioned in the base portion of the inner bottle. 
     
     
         4 . The system of  claim 3 , wherein the second indent is positioned opposite of the first indent on the base portion of the inner bottle. 
     
     
         5 . The system of  claim 1 , wherein the inner bottle has an inner bottle mid-portion that matches a contour of the mid-portion of the outer bottle. 
     
     
         6 . The system of  claim 5 , wherein the inner bottle also includes an inner bottle upper portion connected to the inner bottle mid-portion, and wherein the inner bottle upper portion includes threads configured to receive a lid for the inner bottle. 
     
     
         7 . The system of  claim 1 , further comprising an insulation sleeve positioned between the inner bottle and the outer bottle. 
     
     
         8 . The system of  claim 1 , wherein the first indent is formed by a sidewall of the base portion of the inner bottle. 
     
     
         9 . The system of  claim 8 , wherein the first indent comprises a portion of the sidewall that forms a pocket which extends inward on the inner bottle. 
     
     
         10 . The system of  claim 1 , wherein the outer bottle is rigid. 
     
     
         11 . The system of  claim 1 , wherein the inner bottle is semi-rigid. 
     
     
         12 . A method of making a liquid container system, the method comprising:
 forming an inner bottle that has a base portion with a first diameter, a mid-portion, and an upper portion, wherein forming the base portion includes forming a first indent in the base portion such that the first indent is positioned entirely within the base portion of the inner bottle;   forming an outer bottle that is sized to surround at least a portion of the inner bottle, wherein the outer bottle includes an outer bottle mid-portion that has a second diameter, wherein the second diameter is less than the first diameter; and   inserting the inner bottle into the outer bottle, wherein the inserting includes applying pressure to the base portion of the inner bottle such that the first indent decreases the first diameter of the base portion of the inner bottle such that the first diameter is less than or equal to the second diameter.   
     
     
         13 . The method of  claim 12 , further comprising forming a second indent in the base portion of the inner bottle. 
     
     
         14 . The method of  claim 13 , wherein the second indent is positioned opposite of the first indent on the base portion of the inner bottle. 
     
     
         15 . The method of  claim 12 , wherein the mid-portion of the inner bottle is formed such that it matches a contour of the outer bottle mid-portion. 
     
     
         16 . The method of  claim 12 , further comprising forming threads on the upper portion of the inner bottle, wherein the threads are configured to receive a lid for the inner bottle. 
     
     
         17 . The method of  claim 12 , further comprising forming an insulation sleeve that is sized for placement between the inner bottle and the outer bottle. 
     
     
         18 . The method of  claim 17 , further comprising inserting the inner bottle into the insulation sleeve to form an insulated inner bottle, and wherein inserting the inner bottle into the outer bottle comprises inserting the insulated inner bottle into the outer bottle. 
     
     
         19 . The method of  claim 12 , wherein forming the first indent comprises forming a pocket in a sidewall of the base portion of the inner bottle. 
     
     
         20 . The method of  claim 19 , wherein forming the first indent comprises forming the pocket such that the pocket extends into the inner bottle.
