Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Referring to the accompanying drawings, this embodiment includes a cover core 3 and a plastic cover 2 . The cover core 3 and the plastic cover 2 are fastened together by an octagonal fastening device, that is, the top of the cover core 3 is provided with an octagonal buckle foot 5, and there is a gap between every two adjacent sides of the octagonal buckle foot 5. The gap 7; the inner top of the plastic cover 2 is provided with an octagonal buckle 4 that matches the octagonal buckle 5; the outer side of the lower end of each side of the octagonal buckle 5 is hollowed out, and the outer side of the upper end is a downward slope , forming a button tooth 8 with a cut surface in the shape of a "7"; the inner side of each side of the octagonal button 4 is hollowed out, and a button groove 9 with an inverted "7" shape is formed; the cover cor...

Abstract

The invention relates to a cover of a vacuum cup. The cover of the vacuum cup comprises a cover core and a plastic cover body. The cover of the vacuum cup is characterized in that the top of the cover core is provided with a polygon-shaped buckling foot, and an interval is formed between every two adjacent edges of the polygon-shaped buckling foot; and the top of the inner portion of the plastic cover body is provided with a polygon-shaped buckling position matched with the polygon-shaped buckling foot, and the cover core and the plastic cover body are buckled together from top to bottom to form a whole through buckling teeth on the polygon-shaped buckling foot and buckling grooves in the polygon-shaped buckling position. The cover of the vacuum cup has the advantages that screwing force can be dispersed in multiple directions in use, so that the cover core and the plastic cover body are not prone to disengagement or rotation in the circumferential direction; the buckling structure is small in part quantity, easy to assemble, firm and durable; and in addition, a silicone rubber ring is arranged, and therefore a better water sealing effect and a better heat preservation effect can be achieved.

Description

technical field [0001] The invention relates to a cover, in particular to a cover for a thermos cup. Background technique [0002] In daily life, in order to achieve good water sealing and heat preservation effects, the existing cup lids generally adopt relatively complicated structures. For example, Chinese Patent No. 200620100996.4 discloses a "cover", which includes a cover body and an outer cover, and is characterized in that: a wrench is articulated on the top surface of the cover body, and the lower end of the wrench has two low-level tables. There is a smooth transition between the two table tops; there is also a plunger and a spring in the cover. The top of the plunger is ball-shaped, which is in conflict with the lower end of the wrench. The middle end of the plunger is a connecting column. Cooperate with the sealing ring on the cover body. Because the structure of this type of cup cover is complicated, there are many parts, and the assembly is also complicated, w...
