Description

Technical Field

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

[0002] Nowadays, paper cups, plastic cups, and other cups used in daily life are usually fitted with a cup sleeve to achieve a heat insulation effect, preventing burns or colds when taking the cup out.

[0003] In existing technologies, some paper cups are fitted with sleeves by gluing. This method is not only not environmentally friendly, but also has a complex production process, high cost, and the sleeves cannot be removed or replaced with different sleeves with different patterns, resulting in poor applicability. Other methods involve adjusting the size of the sleeve and fixing it to the outside of the cup through the friction generated by the tight fit between the sleeve and the outer wall of the cup. However, this method is not very secure, and the sleeve is prone to detaching from the cup axially. The structural stability of the two is poor, making it inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to overcome the shortcomings of the prior art and provide an assembled vacuum cup.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An assembled vacuum cup includes a cup body and a cup sleeve;

[0007] The cup wall portion of the cup body protrudes radially outward to form an annular convex wall. The cup sleeve is fitted onto the outer side of the outer wall of the cup body, and the bottom edge of the cup sleeve abuts against the annular convex wall, so that the cup sleeve is fixed to the cup body.

[0008] As shown in the above configuration, when the cup sleeve is fitted onto the outside of the cup body from bottom to top in this embodiment, after installation, the bottom edge of the cup sleeve abuts against the annular convex wall. The annular convex wall effectively restricts the axial displacement of the cup sleeve, preventing it from detaching from the cup body axially. This ensures that the cup sleeve is stably fixed to the cup body and is not easily detached due to external interference. During disassembly, the cup sleeve is pushed downwards with a certain force, allowing the bottom edge to pass over the annular convex wall, thus enabling the cup sleeve to be removed from the cup body. This embodiment of the assembled vacuum cup allows for the assembly and disassembly of the cup sleeve. This design not only optimizes the process and production steps but also reduces costs, resulting in low manufacturing and operating costs. Furthermore, the absence of adhesives or other bonding methods significantly improves the environmental friendliness of the entire cup, facilitating recycling and reuse. Moreover, the detachable cup sleeve allows for easy replacement with various types of cup sleeves, increasing usability and enjoyment, and greatly improving product utilization.

[0009] In one embodiment, the annular convex wall includes a first annular wall and a second annular wall connected sequentially from top to bottom. The first annular wall and the second annular wall are arranged at an angle to form an annular convex structure. The angle between the first annular wall and the outer wall surface of the cup body is α, and the angle between the second annular wall and the outer wall surface of the cup body is β, wherein α is less than β.

[0010] In one embodiment, the height of the first annular wall is less than the height of the second annular wall in the height direction of the cup body.

[0011] In one embodiment, in the height direction of the cup body, the height of the first annular wall is half the height of the second annular wall.

[0012] In one embodiment, the bottom edge of the cup sleeve is folded inward to form an inward folded edge, and the thickness of the inward folded edge is greater than the wall thickness of the cup sleeve.

[0013] In one embodiment, a portion of the inner wall surface of the cup sleeve is spaced apart from a portion of the outer wall surface of the cup body by a predetermined distance; the predetermined distance gradually decreases from bottom to top.

[0014] In one embodiment, the thickness of the cup sleeve is greater than the thickness of the cup body.

[0015] In one embodiment, the maximum diameter of the annular convex wall is greater than the diameter of the bottom opening of the cup sleeve.

[0016] In one embodiment, the height of the cup sleeve is at least 80% of the height of the cup body in the height direction of the cup body.

[0017] As one implementation, the outer wall of the cup sleeve is provided with an anti-slip structure.

[0026] Please see Figures 1 to 3 This embodiment provides an assembled vacuum cup, which includes a cup body 1 and a cup sleeve 2.

[0027] The cup wall portion of the cup body 1 protrudes radially outward to form an annular convex wall 11. The cup sleeve 2 is fitted onto the outer side of the outer wall of the cup body 1, and the bottom edge of the cup sleeve 2 abuts against the annular convex wall 11 so that the cup sleeve 2 is fixed on the cup body 1.

[0028] As can be seen from the above configuration, when the cup sleeve 2 is fitted onto the outside of the cup body 1 from bottom to top in this embodiment, after installation, the bottom edge of the cup sleeve 2 abuts against the annular convex wall 11. The annular convex wall 11 can effectively limit the axial displacement of the cup sleeve 2, preventing the cup sleeve 2 from detaching from the cup body 1 axially, thereby ensuring that the cup sleeve 2 is stably fixed on the cup body 1 and is not easily detached from the cup body 1 due to external interference. During disassembly, the cup sleeve 2 is pushed downward with a certain force, and the bottom edge of the cup sleeve 2 can pass over the annular convex wall 11, thereby allowing the cup sleeve 2 to be removed from the cup body 1. The assembled vacuum cup of this embodiment can realize the assembly and disassembly of the cup sleeve 2. This design not only optimizes the process and production steps, but also reduces costs, resulting in low manufacturing and usage costs. Moreover, it does not use glue or other bonding methods, greatly improving the environmental friendliness of the entire cup and facilitating recycling and reuse. Furthermore, the cup sleeve 2 is detachable, allowing for easy replacement with various types of cup sleeves 2, increasing usability and fun, and greatly improving the utilization rate of the product.

[0029] Preferably, in this embodiment, the annular convex wall 11 includes a first annular wall 111 and a second annular wall 112 connected sequentially from top to bottom. The first annular wall 111 and the second annular wall 112 are arranged at an angle to form an annular protrusion structure. The angle between the first annular wall 111 and the outer wall surface of the cup body 1 is α, and the angle between the second annular wall 112 and the outer wall surface of the cup body 1 is b, where α is less than b. With this arrangement, the first annular wall 111 is located above the second annular wall 112 and can abut against the bottom edge of the cup sleeve 2. The angle α between the first annular wall 111 and the outer wall surface of the cup body 1 is smaller than the angle b between the second annular wall 112 and the outer wall surface of the cup body 1, which makes the cup sleeve 2 easier to install. The second annular wall 112 does not exert much resistance on the cup sleeve 2, and the cup sleeve 2 is more stable when fixed.

[0030] Preferably, in this embodiment, in the height direction of the cup body 1, the height of the first annular wall 111 is less than the height of the second annular wall 112. This arrangement also makes the cup sleeve 2 easier to install, the second annular wall 112 will not exert much resistance on the cup sleeve 2, and the cup sleeve 2 can be more stable when fixed.

[0031] Specifically, in the height direction of the cup body 1, the height of the first annular wall 111 is half the height of the second annular wall 112.

[0032] Preferably, the bottom edge of the cup sleeve 2 is folded inward to form an inner flange 21, and the thickness of the inner flange 21 is greater than the wall thickness of the cup sleeve 2. This improves the strength of the bottom edge of the cup sleeve 2, making it more stable when it abuts against the annular convex wall 11.

[0033] Preferably, in this embodiment, a portion of the inner wall surface of the cup sleeve 2 is spaced apart from a portion of the outer wall surface of the cup body 1 by a predetermined distance, which gradually decreases from bottom to top. This arrangement, with a predetermined distance between a portion of the cup sleeve 2 and the cup body 1, improves heat insulation performance.

[0034] Preferably, the thickness of the cup sleeve 2 is greater than the thickness of the cup body 1, which can improve the heat insulation performance.

[0035] Preferably, the maximum diameter of the annular convex wall 11 is greater than the diameter of the bottom opening of the cup sleeve 2, which allows the cup sleeve 2 to be more stably fixed to the cup body 1.

[0036] Preferably, in the height direction of the cup body 1, the height of the cup sleeve 2 is at least 80% of the height of the cup body 1, which can improve the protective performance of the cup sleeve 2 and make it more practical.

[0037] Preferably, the outer wall of the cup sleeve 2 is provided with an anti-slip structure to facilitate use and prevent the user from sliding during use.

[0038] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
