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 H1 of the square bottle mouth (102) is the same as the height H3 of the bottle body, and after the bottle cap (103) is placed, the height H2 of the square bottle mouth (102) is greater than the height H3 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 H2 minus H3, 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. |
