fig. 3 is an exploded schematic view of fig. 2.
In the drawings:
the bottle cap comprises a bottle cap 1, an internal thread 11, a second sealing ring platform 12, a second inclined annular wall 13, an annular body 14, a bottle mouth 2, an external thread 21, a first sealing ring platform 22, a first inclined annular wall 23 and a bottle body 3.
Detailed Description
The lower wall details embodiments of the invention, examples of which are shown in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The lower wall is exemplary by the embodiments described with reference to the drawings, which are intended to illustrate the invention and are not to be construed as limiting the invention.
Referring to fig. 2 and 3, the present embodiment discloses a bottle mouth structure, which includes a bottle cap 1, a bottle mouth 2 and a bottle body 3, wherein the bottle mouth 2 and the bottle body 3 are an integrated structure, and the bottle cap 1, the bottle mouth 2 and the bottle body 3 are made of environment-friendly plastics.
The middle part of 2 outer walls of bottleneck is equipped with external screw thread 21, and the middle part of 1 inside wall of bottle lid is equipped with and is connected with the internal thread 11 of external screw thread 21 complex, through external screw thread 21 and the cooperation of internal thread 11, can make bottle lid 1 can dismantle sealed locating on bottleneck 2.
The outer wall of the bottle mouth 2 is provided with a first sealing ring platform 22 below the external thread 21, the first sealing ring platform 22 is provided with a first inclined ring wall 23, the radius of the bottom wall of the first inclined ring wall 23 is larger than that of the crest circle of the external thread 21, a second sealing ring platform 12 is arranged below the inner wall of the bottle cap 1 and the internal thread 11, and the second sealing ring platform 12 is provided with a second inclined ring wall 13 attached to the first inclined ring wall 23.
