Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.

Referring to fig. 1-3, the present embodiment provides a cup cover silicone-ring-free sealing cup, which includes a cup cover 10 and a cup body 20, the cup cover 10 includes a cover body 12, an inner cover 13 and an inner plug 14, the inner plug 14 is injection-molded in the inner cover 13 in an insert manner, that is, the inner plug 14 is injection-molded in the inner cover 13 in an insert manner when the inner cover 13 is molded, so as to reduce the tolerance of the assembly accumulation stack so as to control the flatness; the mouth 21 of the cup body 20 is tightly connected with the inner cover 13 at the outer side thereof by screw connection, and the mouth 21 is in interference connection with the inner plug 14 above the mouth 21.

In the present embodiment, the inner plug 14 is used as an important component for sealing water, and in order to further improve the sealing performance of the assembly of the lid 10 and the cup body 20, the dimensional accuracy of the inner lid 13 and the inner plug 14 can be controlled within 0.02 mm after being produced by an injection molding machine through a precision mold by the prior art processing technology.
