Description

Technical Field

[0001] The invention relates to a daily necessity, in particular to a cup cover. Background Art

[0002] A water cup is a common tool in people's life. In order to be easy to carry, many water cups are equipped with a cup lid with a threaded connection. In order to better seal and keep warm, a sealing ring is set on the top of the inner wall of the cup lid for sealing. The existing sealing rings are manufactured separately. Since the sealing ring is very flexible and easily deformed by external force, it is difficult to assemble it with automated equipment. Afterwards, it is manually assembled to the inner wall of the cup lid for fixing. During the assembly process, it is easy to tilt the assembly and fail to meet the requirements. In addition, the manual assembly efficiency is low, and more workers on the assembly line are required, which increases the production cost. Summary of the invention

[0003] In view of the above problems, the present invention aims to provide a cup cover with a simple structure and convenient manufacturing. The sealing ring can be directly injection molded into the cup cover after the cup cover is injection molded, and there is no need for manual assembly of the sealing ring at a later time, thereby achieving high production efficiency.

[0004] The technical solution of the present invention is a cup cover, comprising a cup cover body and a sealing ring, wherein the inner wall of the cup cover body is threaded, and the sealing ring is directly injection-molded on the top of the inner wall of the cup cover body.

[0005] Preferably, an extension handle is provided on the upper surface of the cup cover body, and the extension handle includes two upwardly protruding ribs, a spherical recessed area is provided on the cup cover body between the two ribs, a through hole penetrating the cup cover body is provided at the bottom of the spherical recessed area, a ball head rotating column is hinged between the two ribs at the spherical recessed area, a through hole is provided axially inwardly of the ball head rotating column, an O-ring is provided on the surface of the spherical recessed area, and the O-ring and the sealing ring are integrally formed.

[0006] Preferably, the spherical recessed area extends downward to the lower surface of the cup cover body, and a tube-shaped interface that can be connected to a hose extends from the bottom of the spherical recessed area.

[0007] Preferably, a vent hole is provided between the two ribs above the cup cover body, a sealing strip is provided at the vent hole, the sealing strip, the sealing ring and the O-ring are integrally formed, and a conical pressure head is provided on the lower surface of the ball head rotating column to seal with the sealing strip.

[0008] Preferably, the outer surface of the cup cover body is provided with an anti-skid wrapping strip, and the anti-skid wrapping strip is integrally formed with the sealing strip, the sealing ring and the O-ring.

[0009] The invention has a simple structure and is easy to manufacture. The sealing ring is directly injection-molded into the cup cover after the cup cover is injection-molded, and there is no need to manually assemble the sealing ring at a later stage, so the production efficiency is high.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 9 As shown, the present invention discloses a cup cover, comprising a cup cover body 1 and a sealing ring 2. The inner wall of the cup cover body 1 is threaded, and the sealing ring 2 is directly injection-molded on the top of the inner wall of the cup cover body 1.

[0022] Preferably, an extension handle 3 is provided on the upper surface of the cup cover body 1, and the extension handle 3 includes two upwardly protruding ribs, a spherical recessed area 4 is provided on the cup cover body 1 between the two ribs, a through hole 5 penetrating the cup cover body 1 is provided at the bottom of the spherical recessed area 4, a ball head rotating column 6 is hinged between the two ribs at the spherical recessed area 4, a through hole is provided axially inside the ball head rotating column 6, an O-ring 7 is provided on the surface of the spherical recessed area 4, and the O-ring 7 and the sealing ring 2 are integrally formed.

[0023] Preferably, the spherical recessed area 4 extends downward to the lower surface of the cup cover body 1, and a tubular interface 8 that can be connected to a hose extends from the bottom of the spherical recessed area 4 and can be used to insert a plastic soft straw.

[0024] Preferably, an air hole 9 is provided between the two ribs above the cup cover body 1, and a sealing strip 10 is provided at the air hole 9. The sealing strip 10, the sealing ring 2 and the O-ring 7 are integrally formed. The lower surface of the ball head rotating column 6 has a conical pressure head 11 that is adapted to seal with the sealing strip 10. After the ball head rotating column 6 is rotated upright, the internal through hole is connected with the through hole 5 of the cup cover body 1. After the ball head rotating column 6 is rotated down, the conical pressure head 11 presses the sealing strip 10 to seal the air hole 9.

[0025] Preferably, an anti-skid wrapping strip 12 is provided on the outer surface of the cup cover body 1 , and the anti-skid wrapping strip 12 is integrally formed with the sealing strip 10 , the sealing ring 2 , and the O-ring 7 .

[0026] The present invention directly injects the sealing ring 2 into the cup cover body 1, omitting the later assembly process, saving production costs, and improving production efficiency. The sealing ring 2 will not fall off during use. The entire structure is compact and novel, and is suitable for home and outdoor use.

[0027] The above description is only a preferred embodiment of the present invention and does not impose any form of limitation on the invention. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
