Telescopic Square Bottle

Abstract

A telescopic square bottle includes a square bottle body ( 101 ) joined with a square bottle mouth ( 102 ) in one piece, where when no bottle cap ( 103 ) is placed on the square bottle mouth ( 102 ), the height H 1 of the square bottle mouth ( 102 ) is the same as the height H 3 of the bottle body, and after the bottle cap ( 103 ) is placed, the height H 2 of the square bottle mouth ( 102 ) is greater than the height H 3 of the bottle body. The square bottle body ( 101 ) has a rounded square-shaped groove ( 108 ) at the bottom, where the inner boundary of the groove ( 108 ) is consistent with the outer boundary of the bottle cap ( 103 ) in shape and size, and the depth of the groove ( 108 ) is equal to a difference value of H 2 minus H 3, so that the square bottle can be fitted to another same square bottle having a bottle cap, thereby achieving a purpose of being telescopic and saving more space during transportation and storage. The present invention further provides a square bottle mouth ( 102 ), which facilitates pouring of a substance inside a bottle.

1 . A telescopic square bottle, comprising a square bottle body  101  joined with a square bottle mouth  102  in one piece. 
     
     
         2 . The square bottle body according to  claim 1 , wherein the square bottle body is rounded square-shaped. 
     
     
         3 . The square bottle mouth according to  claim 1 , wherein the outer boundary of the square bottle mouth is round-shaped, and the inner boundary of the square bottle mouth is rounded square shaped. 
     
     
         4 . The square bottle mouth according to  claim 3 , wherein when no bottle cap is placed, the height H 1  of the square bottle mouth is the same as the height H 3  of the bottle body. 
     
     
         5 . The square bottle mouth according to  claim 3 , wherein after a bottle cap is placed, the height H 2  of the square bottle mouth is greater than the height H 3  of the bottle body  101 . 
     
     
         6 . The square bottle body according to  claim 1 , wherein there is a rounded square-shaped groove at the bottom of the bottle, the inner boundary of the groove is consistent with the outer boundary of a bottom cap  103  in shape and size; and the depth of the groove is equal to a difference value of H 2  minus  113 . 
     
     
         7 . The square bottle mouth according to  claim 5 , wherein after the bottle cap is placed, the bottle cap can be fitted to a groove of another same square bottle, thereby achieving a purpose of being telescopic.
