Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; to better illustrate the embodiments of the present invention, some components of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product.

Referring to fig. 1 to 5, the bottle cap convenient for liquid return comprises an upper cap 1 and a lower cap 2, wherein the upper cap 1 is connected with the lower cap 2 through a hinge 3, and the bottle cap is characterized in that an oil seal ring 2a is arranged at the top of the lower cap 2, an oil passing groove 2b is formed in the middle of the lower cap 2, an annular step 2c is reserved between the oil passing groove 2b and the oil seal ring 2a, the width of the annular step 2c is less than one millimeter, and a sealing assembly 4 is fixedly arranged at the top of the annular step 2 c.

A plurality of buffer pieces 2d are arranged on the side surface of the inner edge of the annular step 2 c. Through setting up buffer piece 2d for buffer piece 2d plays the effect of buffering when can pouring out liquid in the bottle, and buffer piece 2d still plays filterable effect.

The bottom of the annular step 2c is fixedly provided with an insert ring 2 e. By providing the insert ring 2e, the insert ring 2e is inserted into the bottle mouth when the lower cap 2 is mounted, and the liquid in the bottle is sealed.

The bottom of the inner edge of the lower cover 2 is provided with a first annular clamping strip 2 f. Through the effect of first annular card strip 2f for lower cover 2 can with the joint between the bottleneck.

Sealing assembly 4 includes that the annular tears pulling-on piece 4a, extend strip 4b and pull ring 4c, the bottom outer fringe that the pulling-on piece 4a was torn to the annular and the top inner edge fixed connection of annular step 2c, extend strip 4b fixed mounting tear the pulling-on piece 4a at the annular, and extend strip 4b is located the annular and tears one side that pulling-on piece 4a is close to hinge 3, pull ring 4c fixed mounting is at the top that extends strip 4b, and pull ring 4c is the tilt up setting, and the pull-on piece 4a is torn by the annular wholly inwards sunken outside. When it is desired to open the oil sump 2b, the pull ring 4c is pulled upward by the user, so that the pull ring 4c pulls the annular tear tab 4a through the extension strip 4b, so that the joint of the annular tear tab 4a and the annular step 2c is broken.

The top of the lower cover 2 is provided with an extension ring 2h, the top of the outer edge of the extension ring 2h is provided with an annular bulge 2j, and the inner edge of the upper cover 1 is provided with a second annular clamping strip 1a clamped with the annular bulge 2 j. By arranging the second annular clamping strip 1a and the annular bulge 2j, when the upper cover 1 is covered, the upper cover 1 can be tightly covered on the lower cover 2.
