CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority from Chinese Patent Application No. 202120683335.3, filed on Apr. 4, 2021. The content of the aforementioned application, including any intervening amendments thereto, is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The disclosure relates to thermal insulation products, and more specifically to a thermal insulation device for a beverage can or bottle, which facilitates the carrying of the beverage can or bottle and has a cold insulation performance.

BACKGROUND

The development of society and the progress of science and technology contribute to the improvement of standard of living and quality of life of residents. stainless-steel products have been increasingly used recently, and stainless-steel vacuum vessels for different application purposes have been constantly developed. For example, Chinese Patent No. 211469114U discloses a thermal insulation vessel special for beverage bottles, in which when the beverage bottle extends from an inner side of a central limiting hole of a rubber-coated punching cover to an outer side, a flexible limiting piece is locked on a neck of the beverage bottle to lock the beverage bottle. This thermal insulation vessel has advantages of simple and reasonable structure, good cold insulation and locking performance and high portability, and the beverage can be directly enjoyed by opening the beverage bottle cap. Unfortunately, this thermal-insulation vessel still struggles with the following defects. (1) The rubber-coated punching cover is threadedly connected to a stainless-steel thermal insulation cup body, so when a beverage bottle to be refrigerated is put into the thermal insulation cup body and fixed by screwing the rubber-coated punching cover, it is generally not easy to screw the rubber-coated punching cover due to a friction contact between the flexible limiting piece and the beverage bottle neck. In addition, if the beverage bottle is rotated together, it is extremely inconvenient to operate and difficult to tighten. (2) The stainless-steel vacuum vessel is prone to reacting with some ingredients in the carbonated beverages, milk, beer and other drinks stored therein for a long time, causing the beverage to deteriorate. There is still a lack of an effective way to solve the above problems.

SUMMARY

In order to solve the above-mentioned technical problems, the disclosure provides a thermal insulation device for a beverage can or bottle with simple and reasonable structure and flexible and easy operation, which can be used as both a thermal insulation device and a thermal insulation cup.

Technical solutions of this application are described as follows.

A thermal insulation device for a beverage can or bottle, comprising:

a plastic-coated lid; and

a stainless-steel vacuum cup body;

wherein the stainless-steel vacuum cup body is provided with a cavity to accommodate the beverage can or bottle; the plastic-coated lid comprises a hard plastic cover and a plastic rubber sleeve, wherein the plastic rubber sleeve is formed at a mouth portion of the hard plastic cover through overmolding; the plastic rubber sleeve is provided with a central limiting hole matched with the beverage can or bottle; a circumference of the central limiting hole is provided with a flexible rubber pressing ring extending outward to press the beverage can or bottle; an outer wall of the hard plastic cover is provided with a clamping groove; and the clamping groove is provided with a silicone sealing sleeve in sealing fit with an inner wall of the stainless-steel vacuum cup body.

In some embodiments, the silicone sealing sleeve is provided with at least two sealing clamp rings arranged up and down; the at least two sealing clamp rings are in tight fit with the inner wall of the stainless-steel vacuum cup body; and the at least two sealing clamp rings are respectively provided with a beveled opening for reducing a press-in or pull-out resistance.

In some embodiments, the hard plastic cover is provided with a connecting column; and the connecting column fixedly connected with the plastic rubber sleeve.

In some embodiments, the stainless-steel vacuum cup body comprises a stainless-steel shell and a stainless-steel liner; and

the stainless-steel shell is fixedly sleeved on the stainless-steel liner; and a thermal insulation vacuum layer is arranged between the stainless-steel liner and the stainless-steel shell

Compared to the prior art, the present disclosure has the following beneficial effects.

(1) The flexible rubber pressing ring is pressed on the beverage can or bottle during using, which ensures that a beverage can or bottle carried will not shake. The silicone sealing sleeve is sealedly fixed at the inner wall of the stainless-steel vacuum cup body via the sealing clamp rings, which ensures that the beverage can or bottle carried will not fall off from the stainless-steel vacuum cup body. Moreover, three sealing clamp rings can ensure a direct tensioning force of greater than 20 N. It has a simple structure, a reliable connection and easy operation.

(2) Since a spout of the beverage can or bottle is exposed on the outside, there is no need to open the plastic-coated lid when drinking. The spout can be opened to drink easily, which is not only convenient, but ensure a better cold insulation.

(3) The thermal insulation device can be used as both a thermal insulation device for beverage can or bottle and a thermal insulation cup.
