Bottle easy to carry and clean

Abstract

A bottle that is easy to carry and clean includes a bottle body and a bottle cap. The bottle body includes an upper section and a lower section. The lower section has a lower chamber therein and an opening at a top end thereof. The upper section has an upper chamber therein and a bottle mouth at a top end thereof. The upper section is detachably coupled to the lower section through a coupling portion and closes the opening. The upper chamber communicates with the lower chamber. The bottle body has a flat configuration with a width greater than twice a thickness after the upper section and the lower section are combined together. The bottle cap is configured to cover the bottle mouth.

What is claimed is: 
     
         1 . A bottle, comprising:
 a bottle body, including an upper section and a lower section, the lower section having a lower chamber therein and an opening at a top end thereof, the upper section having an upper chamber therein and a bottle mouth at a top end thereof; the upper section being detachably coupled to the lower section through a coupling portion and closing the opening, the upper chamber communicating with the lower chamber; the bottle body having a flat configuration with a width greater than twice a thickness after the upper section and the lower section are combined together; and   a bottle cap, configured to cover the bottle mouth.   
     
     
         2 . The bottle as claimed in  claim 1 , wherein the coupling portion is a pair of side coupling pieces extending downward from two sides of the upper section, and the side coupling pieces are pressed and secured to an outer wall surface of the lower section. 
     
     
         3 . The bottle as claimed in  claim 2 , wherein the side coupling pieces extend downward from the two sides, parallel to the direction of the thickness, of the upper section. 
     
     
         4 . The bottle as claimed in  claim 3 , wherein the outer wall surface of the lower section is recessed with a pair of stepped portions for accommodating the side coupling pieces, so that the upper section is flush with the lower section after being combined with the lower section. 
     
     
         5 . The bottle as claimed in  claim 4 , wherein each side coupling piece has a protrusion protruding toward the outer wall surface of the lower section, and the outer wall surface of the lower section has a groove for the protrusion to be inserted and positioned therein. 
     
     
         6 . The bottle as claimed in  claim 4 , wherein the upper section and the lower section are sealed with a water stop ring. 
     
     
         7 . The bottle as claimed in  claim 1 , wherein after the upper section and the lower section are combined together, the bottle body has a trapezoidal prism shape, the bottle body has a top end and a bottom end, the top end has a width less than that of the bottom end, the bottle body has an average width at a position half a height of the bottle body, the thickness from the top end to the bottom end of the bottle body is uniform, and the average width is greater than twice the thickness.
