In order to achieve the above purpose, the solution of the present invention is:

a bottle cap comprises an integrally formed plastic cap body, wherein the cap body is cylindrical and is provided with an accommodating cavity, the state that the opening part of the cap body in the accommodating cavity faces downwards is taken as an example, the upper surface of the cap body is an outer top surface, the upper side surface of the accommodating cavity is an inner top surface, the outer peripheral side surface of the cap body is an outer side surface, the inner peripheral side surface of the cap body is an inner side surface, the side walls where the outer top surface and the inner top surface are located are upper side walls, and the side walls where the inner side surface and the outer side surface are located are peripheral side walls;

outer top surface is convex sphere, interior top surface be with the corresponding sunken sphere of outer top surface, go up the lateral wall with still be provided with round chamfer between the week edge lateral wall, the axis of interior top surface with still be provided with first cyclic annular sand grip between the edge of interior top surface, be provided with the cyclic annular sand grip of second on the outer edge of interior top surface, go up the lateral wall and avoid first cyclic annular sand grip with each wall thickness of the position of the cyclic annular sand grip of second is unanimous, the lower terminal surface of first cyclic annular sand grip with the lower terminal surface of the cyclic annular sand grip of second is located the coplanar.

Furthermore, the number of the first annular convex strips is two, and the two first annular convex strips are arranged along the same axis.

Furthermore, the number of the first annular convex strips is one.

Further, the cover body is a polypropylene cover body.

Furthermore, the peripheral side wall is provided with threads, the threads are located on the inner peripheral side face, and the wall thickness of the peripheral side wall at each position avoiding the threads is consistent.

After the structure is adopted, the utility model relates to a bottle lid has following beneficial effect: the outer top surface of lid is convex sphere, interior top surface is the sunken sphere corresponding with outer top surface, it is more even to compare current integrated into one piece's spherical cover and has avoided everywhere wall thickness distribution on first cyclic annular sand grip and the second cyclic annular sand grip position on the last lateral wall of messenger's lid when having reduced the raw materials that use, thereby reduce the probability that the lateral wall contracts, the lid can be formed by integrated into one piece, only need use same set of mould at the shaping in-process, production can be accomplished to same material one shot forming process, the production process is simple, production efficiency is higher, furthermore, interior top surface has reduced the material of the medial surface of lid for the sunken sphere corresponding with outer top surface, thereby reach the purpose of sparingly raw materials.

The lower end face of the first annular raised line and the lower end face of the second annular raised line are located on the same plane, so that the polyethylene foam gasket can be supported, the consumed materials are less compared with those on the plane of the inner side face of the whole spherical bottle cap, and the raw materials are further saved.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1-3, the bottle cap includes an integrally formed cap body 1, the cap body 1 is a plastic cap body, specifically, the cap body 1 is a polypropylene cap body, the cap body 1 is cylindrical, the cap body 1 has a receiving cavity, the receiving cavity is a cylindrical cavity, the receiving cavity has a mouth portion communicated with the outside, taking a state that the cap body 1 faces downward at the mouth portion of the receiving cavity as an example, the upper surface of the cap body 1 is an outer top surface 2, the upper side surface of the receiving cavity is an inner top surface 3, the outer peripheral side surface of the cap body 1 is an outer side surface 4, the inner peripheral side surface of the cap body 1 is an inner side surface, the side walls where the outer top surface 2 and the inner top surface 3 are located are upper side walls 5, and the side walls where the inner side surface and the outer side surface. The peripheral side wall is provided with threads 6, and the threads 6 are located on the inner peripheral side surface.

Outer top surface 2 is convex sphere, and interior top surface 3 is the sunken sphere corresponding with outer top surface 2, and outer top surface 2 and interior top surface 3's centre of sphere all lie in same one side of lid 1, go up lateral wall 5 and week and still be provided with round chamfer 7 along between lateral wall 6, and round chamfer 7's design can make lid 1 can not prick the hand convenient to use when the contact.

Still be provided with first cyclic annular sand grip 8 between the axis of interior top surface 3 and the edge of interior top surface 3, the quantity of first cyclic annular sand grip 8 can be one, two or many, when the quantity of first cyclic annular sand grip 8 is two or many, two or many first cyclic annular sand grip 8's radius differs and the coaxial line sets up, be provided with the cyclic annular sand grip 9 of second on the outer edge of interior top surface 3, the quantity of the cyclic annular sand grip 9 of second is one, the cyclic annular sand grip 9 of second is used for supporting with the week of current cosmetic bottle bottleneck and realizes sealedly, the width of first cyclic annular sand grip 8 is less, the width of the cyclic annular sand grip 9 of second is great, the difference between the outer radius and the inner radius of above-mentioned width finger cyclic annular sand grip, the lower terminal surface of first cyclic annular sand grip 8 and the lower terminal surface of the cyclic annular sand grip 9 of second are located the coplanar.

The radial thickness of the first annular ridge 8 is not more than 60% of the average wall thickness of the lid body 1.
