Vacuum cup cover and vacuum cup thereof

Abstract

The invention discloses a vacuum cup cover and a vacuum cup thereof. The vacuum cup cover comprises an outer cover and an inner cover, wherein a hardware snap ring with a barb structure is fixedly arranged on the inner side of the mouth of the outer cover; a sealing ring is arranged between the hardware snap ring and the outer side of the inner cover; and the outer cover and the inner cover are fixedly fastened through the hardware snap ring. The hardware snap ring with the barb structure is connected to the inner cover and the outer cover of the cup cover, so that the inner cover and the outer cover are firmly connected, and loosening and falling are less likely to occur. Meanwhile, a heat insulation block with a better heat insulation effect is arranged in an inner cover cavity of the inner cover, so that the vacuum cup cover and the vacuum cup provided with the cup cover are simpler and more convenient to produce and install, better in quality, more attractive and better in sealingperformance.

Description

technical field [0001] The invention relates to a thermos cup cover and a thermos cup. Background technique [0002] The water cup is an important container that can meet people's drinking water needs. It exists in every corner of people's daily life. The heat exchange speed of the external cold environment is used to delay heat dissipation and achieve the purpose of heat preservation. In order to achieve the thermal insulation performance of the thermos cup, most of the cup liner of the thermos cup adopts a double-layer vacuum structure made of metal. Its advantages such as high structural strength and good anti-drop performance have been welcomed by consumers. In order to ensure the thermal insulation performance of the thermos cup, the cup lid of the thermos cup also adopts thermal insulation material, which can further enhance the thermal insulation performance of the thermos cup. The thermos cup lid in the prior art generally includes an inner lid and an outer lid, an...

AI Technical Summary

Problems solved by technology

The thermos cup lid in the prior art generally includes an inner lid and an outer lid, and the inner lid and the outer lid are crimped and assembled together, so as to realize the fixing between the inner lid and the outer lid. The fit between the lids is usually through interference fit to achieve the fast connection between the two. After the lid is used for a long time, the size of the inner lid and the outer lid will shrink and deform due to cold and heat, and it is easy to produce a fit between the two. Loose or fall off, and at the same time make it easy for water to enter between the inner cover and the outer cover, and the gap between the inner cover and the outer cover is easy to accumulate water stains, which is difficult to clean

Generally, when the outer cover is made of hardware, most of the cooperation with the inner cover adopts a mold-molded hemming structure. The cooperation between the outer cover and the inner cover of this structure is easy to loosen, and the process structure is complicated, and the scrap rate and cost of product production will be higher. In addition, it is difficult to achieve secondary surface treatment on the outer cover, which cannot meet the diversified industrial design
