Detailed Description

The technical solutions of the embodiments of the present utility model will be explained and illustrated below with reference to the drawings of the embodiments of the present utility model, but the following embodiments are only preferred embodiments of the present utility model, and not all embodiments. Based on the examples in the implementation, other examples that can be obtained by a person skilled in the art without having to make creative efforts fall within the protection scope of the present utility model.

Embodiment one:

as shown in fig. 1 to 3, the embodiment provides a vacuum cup, which comprises an inner liner layer 1 and an outer liner layer 2, wherein the inner liner layer 1 and the outer liner layer 2 form an inner liner together, and the inner liner layer 1 is arranged inside the outer liner layer 2. The outside of the outer layer 2 of the inner container is provided with an outer shell 3, and vacuum is formed between the outer shell 3 and the inner container. The cup bottom of the vacuum cup is in an up-down direction from the cup bottom to the cup opening, wherein the cup bottom is arranged at the bottom, and the cup opening is arranged at the top.

The inner liner layer 1 is made of titanium material, and heavy metal can not be separated out when the titanium material is used as the inner liner of the thermos cup, but the titanium material has good heat conduction performance and is not beneficial to heat preservation. Therefore, the inner liner outer layer 2 made of stainless steel material is provided outside the inner liner inner layer 1 made of titanium material. A vacuum layer is arranged between the outer layer 2 of the inner container and the outer shell 3. The vacuum layer is fixedly provided with a material capable of absorbing gas, so that the vacuum layer can be changed into vacuum after the inner container is fixed with the outer shell 3, and the technology is a common technology in the field when vacuum treatment is carried out on the vacuum cup, and is not repeated here.

The outer casing 3 is fixed to the inner liner outer layer 2 and forms a seal, and specifically, in this embodiment, the outer casing 3 and the inner liner outer layer 2 are fixed in a sealing manner by roll welding at a certain distance below the cup opening. Further, the distance is 3-10mm. The outer shell 3 and the inner container outer layer 2 form a vacuum layer, and the welding position of the outer shell 3 and the inner container outer layer 2 is a first welding point 4.

By using the titanium material, the inner container can not separate out heavy metals harmful to human bodies, so that the thermos cup is safer. However, because titanium material's heat conductivility is good, is unfavorable for heat preservation, so need through the inner bag inlayer of inner bag outer with improve heat preservation performance that other metals made outside, behind the double-deck inner bag of setting up, compare the thermos cup that only has the individual layer inner bag, this thermos cup's heat preservation effect is better.

A circle of concave bands 6 protruding into the cup are arranged on the outer layer 2 of the inner container from the first welding point upwards. The concave belt 6 is at a certain distance from the cup mouth, and the distance is 2-9mm from the cup mouth. As shown in fig. 1 and 2, the present embodiment does not limit the outer shape of the thermos cup.

The inner liner inner layer 1 turns outwards and downwards at the cup opening to form a turned-over edge 5, the tail end of the turned-over edge 5 is bent and pressed into the concave belt 6, and the tail end of the turned-over edge 5 does not exceed the concave belt 6, so that the tail end of the turned-over edge 5 is matched with the shape of the concave belt 6 and is attached to the concave belt 6. The inner container outer layer 2 is positioned between the inner container inner layer 1 and the flanging 5, and the tail end of the flanging 5 in the concave belt 6 is fixed with the inner container outer layer 2 through roll welding.

Waste materials can be generated during roll welding, the waste materials can enter the concave belt 6, the concave belt 6 protrudes inwards of the cup, and a mouth of a user is separated from the waste materials by a certain distance during use, so that irregular waste materials can be prevented from being directly contacted with the mouth during use, and the comfort level is higher during use. The welding position between the inner container outer layer 2 and the inner container inner layer 1 is separated from the first welding point 4 by the concave belt 6, so that the two layers cannot influence each other.

The vacuum cup has the advantages of simple structure, convenient manufacture, good heat preservation effect and capability of realizing the fixed sealing between the inner containers made of different metals in the vacuum cup.

Embodiment two:

as shown in fig. 4 to 6, this embodiment provides a thermos cup including an inner liner layer 1, an outer liner layer 2 and an outer shell 3, and is different from the first embodiment in that the present embodiment does not use a welding technique when assembling the inner liner layer 1 and the outer liner layer 2. Specifically, the inner liner layer 1 and the outer liner layer 2 are turned outwards and compacted at the cup opening, so that the inner liner layer 1 and the outer liner layer 2 are completely attached at the cup opening, the inner liner layer 1 is turned outwards and then extends downwards to the position of the concave belt 6, and the tail end of the turned edge 5 is pressed along the shape of the concave belt 6. This solution does not produce scrap at the recessed band 6. As shown in fig. 7, the outer liner layer 2 is welded and fixed with the outer casing 3 after being turned outwards to form a vacuum layer. The welding point is positioned on the inner side of the flanging 5 of the inner layer 1 of the liner. The positions of the flange 5 and the concave band 6 on the side wall are not limited in this embodiment, and in particular, when the cup body is of an internal thread type or a non-thread type, the concave band 6 may be disposed in the middle of the cup body, that is, the concave band 6 is close to the cup mouth and the cup bottom. And the concave belt 6 is filled with a silica gel material 7 to cover the flanging and prevent scalding. As shown in fig. 4 and 5, the present embodiment does not limit the outer shape of the thermos cup.

The scheme has simple structure and convenient manufacture, and can not form welding waste. And moreover, the fixing and sealing between the inner containers made of different metals in the vacuum cup can be realized, and the heat preservation effect is good.
