DETAILED DESCRIPTION OF EMBODIMENTS

[0022] As shown in FIGS. 1 and 3, an embodiment of this application provides a thermal insulation device for a beverage can or bottle, including a plastic-coated lid 1 and a stainless-steel vacuum cup body 2. The stainless-steel vacuum cup body 2 is provided with a cavity to accommodate a beverage can or bottle 3. The plastic-coated lid 1 includes a hard plastic cover 6 and a plastic rubber sleeve 5, where the plastic rubber sleeve 5 is formed at a mouth part of the hard plastic cover 6 through overmolding. The plastic rubber sleeve 5 is provided with a central limiting hole match with the beverage can or bottle 3. A circumference of the central limiting hole is provided with a flexible rubber pressing ring 4 extending outward to press the beverage can or bottle 3. An outer wall of the hard plastic cover 6 is provided with a clamping groove 10. The clamping groove 10 is provided with a silicone sealing sleeve 7 in sealing fit with an inner wall of the stainless-steel vacuum cup body 2. During using, a cooled or frozen beverage can or bottle 3 is placed in the stainless-steel vacuum cup body 2. The central limiting hole of the plastic-coated lid 1 is sleeved on the beverage can or bottle 3 and then press the plastic-coated lid 1 to enable the flexible rubber pressing ring 4 to press the beverage can or bottle 3 for locking. The silicone sealing sleeve 7 is tightly matched with the stainless-steel vacuum cup body 2 for fixing.

[0023] In order to ensure a reliable seal and firmly connection between the plastic-coated lid 1 and the stainless-steel vacuum cup body 2, the silicone sealing sleeve 7 is provided with at least two sealing clamp rings 8 arranged up and down. The sealing clamp rings 8 are in tight fit with the inner wall of the stainless-steel vacuum cup body 2. The sealing clamp rings 8 are respectively provided with a beveled opening 9 for reducing a press-in or pull-out resistance. In this embodiment, the silicone sealing sleeve 7 is provided with three sealing clamp rings 8 arranged at top, middle and bottom of the silicone sealing sleeve 7, which can ensure a direct tensioning force of greater than 20 N. In addition, with more sealing clamp rings 8 comes greater tensioning force.

[0024] In order to ensure a firmly connection between the plastic rubber sleeve 5 and the hard plastic cover 6, the hard plastic cover 6 is provided with a connecting column 14 fixedly connected with the plastic rubber sleeve 5.

[0025] In order to ensure a thermal insulation effect, the stainless-steel vacuum cup body 2 includes a stainless-steel shell 11 and a stainless-steel liner 12. The stainless-steel shell 11 is fixedly sleeved on the stainless-steel liner 12. A thermal insulation vacuum layer 13 is arranged between the stainless-steel liner 12 and the stainless-steel shell 11.

[0026] The above are only preferred embodiments of the present disclosure, which are not intended to limit the disclosure. Any modifications and improvements made by those skilled in the art without departing from the spirit of the disclosure should fall within the scope of the disclosure defined by the appended claims.
