A type of cup

Abstract

This utility model discloses a cup, comprising: an outer shell and an inner liner, the inner liner being disposed inside the outer shell, and a sealed cavity being formed between the outer wall of the inner liner and the inner wall of the outer shell; the upper opening edge of the inner liner is folded towards the outer shell to form a first folded edge; the end of the first folded edge extends to and abuts against the outer wall of the outer shell, and the end of the first folded edge is fixedly connected to the outer wall of the outer shell by welding. The technical solution of this utility model, by folding the inner liner onto the outer wall of the outer shell, allows for a smoother arc-shaped structure; the welding at this location reduces the welding breakage rate, improves the yield, and facilitates polishing.

Description

Technical Field

[0001] This utility model relates to the field of cup technology, and in particular to a cup. Background Technology

[0002] Traditional cups, which consist of an inner liner and an outer shell, require welding to connect the two. Traditionally, the welding is done at the top to seal the inner liner and outer shell. This method, with the weld at the top, makes it easy to cut your lip when using the cup. Alternatively, the inner liner can be partially rolled up onto the inner wall of the outer shell for welding and sealing. This method is prone to detachment.

[0003] In conclusion, how to design a cup that is not easily detached from the solder joint and does not irritate the mouth is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is to provide a cup, comprising: shell; The inner liner is located inside the outer shell, and a sealed cavity is formed between the outer wall of the inner liner and the inner wall of the outer shell; The upper opening edge of the inner liner is rolled towards the outer shell to form the first folded edge; The end of the first folded edge extends to and abuts against the outer wall of the outer shell, and the end of the first folded edge is fixedly connected to the outer wall of the outer shell by welding.

[0005] The cross-section of the first fold is arc-shaped. The technical solution of this utility model, by folding the inner liner onto the outer wall of the outer shell, makes the arc-shaped structure smoother; and the welding at this point can reduce the welding failure rate, improve the yield rate; and it is easy to polish.

[0009] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0010] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0011] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "several" or "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0012] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model. This utility model proposes a cup that is not easily detached from the solder and does not irritate the mouth.

[0014] The cup proposed in this utility model will be described below in specific embodiments: In the technical solution of this embodiment, such as Figure 1 , Figure 2 As shown, a cup includes: Outer shell 1; The inner liner 2 is located inside the outer shell 1, and a sealed cavity 3 is formed between the outer wall of the inner liner 2 and the inner wall of the outer shell 1; The upper opening edge of the inner liner 2 is rolled towards the outer shell 1 to form the first folded edge 21; The end of the first folded edge 21 extends to and abuts against the outer wall of the outer shell 1, and the end of the first folded edge 21 is fixedly connected to the outer wall of the outer shell 1 by welding.

[0015] The cross-section of the first fold 21 is arc-shaped.

[0016] This application folds the inner liner 2 onto the outer wall of the outer shell 1, and the end of the first folded edge 21 is fixedly connected to the outer wall of the outer shell 1 by welding. This welding method can reduce the welding breakage rate, improve the yield, and facilitate polishing. The arc-shaped structure allows for smoother operation. The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
