Description

Technical Field

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

[0002] To improve heat insulation performance, existing disposable cups, as shown in patent application number CN201821475459.7, include an inner and outer cup body with an insulating layer between them. While these disposable cups offer good heat insulation, the inner and outer cup bodies are integrally molded, making it impossible to adjust their heat insulation performance. For example, in winter, good heat insulation is required, while in summer, good heat dissipation is needed. Existing disposable cups cannot adjust their heat insulation performance according to these needs. Utility Model Content

[0003] To address the shortcomings of existing disposable cups that cannot adjust their heat preservation performance, this invention proposes a heat-insulating disposable cup with adjustable heat preservation performance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A heat-insulating disposable cup includes an inner cup body and an outer cup sleeve. The outer surface of the inner cup body is provided with a groove. The outer cup sleeve is rotatably connected to the outer surface of the inner cup body and is axially fixed. The inner wall of the outer cup sleeve fits against the outer wall of the inner cup body. The outer cup sleeve is provided with heat dissipation vents through the inner and outer surfaces.

[0006] The disposable cup has a heat dissipation state and a heat preservation state. In the heat dissipation state, the groove is connected to the outside through the heat dissipation vent. In the heat preservation state, the groove and the heat dissipation vent are offset, and the outer cup sleeve and the groove form a first heat preservation cavity.

[0007] With the above settings, rotating the outer cup sleeve allows you to switch the state of the disposable cup as needed to adjust its heat preservation performance.

[0008] Furthermore, the bottom of the inner cup has a double-layer structure, forming a second heat-insulating cavity.

[0009] The above settings improve the heat retention performance of the bottom of the disposable cup.

[0010] Furthermore, a limiting rib is fixedly connected to the lower end of the inner cup body along the outer periphery, and the lower end of the outer cup sleeve abuts against the limiting rib.

[0011] The above settings prevent the outer cup sleeve from slipping down.

[0012] Furthermore, a conical surface is provided on the lower side of the limiting rib, the lower end of the conical surface is inclined inward and extends to the outer wall of the inner cup body, and the height of the limiting rib is less than or equal to 2mm.

[0013] The above settings make it easy to attach the outer cup sleeve upwards.

[0014] Furthermore, the rim of the inner cup body is folded outward to form a reinforcing rib.

[0015] The above design enhances the rigidity of the inner cup's rim, preventing deformation during drinking.

[0016] Furthermore, the groove is rectangular and extends vertically. Multiple grooves are provided both vertically and circumferentially. The distance between two adjacent grooves is equal to the length of the groove, and the ratio of the distance between two adjacent grooves in the circumferential direction to the width of the groove is between 3 and 5.

[0017] Furthermore, the inner cup body has a frustum structure that is larger at the top and smaller at the bottom. Attached Figure Description

[0023] Figure 6 This is a schematic diagram of a disposable cup in a heat dissipation state, as shown in the example. Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] like Figures 1 to 6 A heat-insulating disposable cup includes an inner cup body 3 and an outer cup sleeve 4. The outer surface of the inner cup body 3 is provided with a groove 5. The outer cup sleeve 4 is rotatably connected to the outside of the inner cup body 3 and is axially fixed. The inner wall of the outer cup sleeve 4 fits against the outer wall of the inner cup body 3. The outer cup sleeve 4 is provided with heat dissipation vents 6 through the inner and outer sides.

[0026] The disposable cup has a heat dissipation state and a heat preservation state. In the heat dissipation state, the groove 5 is connected to the outside through the heat dissipation vent 6. In the heat preservation state, the groove 5 and the heat dissipation vent 6 are offset, and the outer cup sleeve 4 and the groove 5 form a first heat preservation cavity.

[0027] By rotating the outer cup sleeve 4, the state of the disposable cup can be switched as needed to adjust its heat preservation performance.

[0028] Specifically, the inner cup body 3 and the outer cup sleeve 4 are made of food-grade plastic. The shape of the groove 5 is not limited, but the ratio of the depth of the groove 5 to the thickness of the inner cup body 3 is approximately 1 / 2. The shape and number of heat dissipation vents 6 are the same as those of the groove 5. The thickness of the outer cup sleeve 4 is approximately equal to the thickness of the inner cup body 3. The upper end of the outer cup sleeve 4 is close to the rim of the inner cup body 3, and the lower end of the outer cup sleeve 4 is close to the bottom of the inner cup body 3, giving the outer cup sleeve 4 good heat insulation performance. After hot drinks are placed inside the inner cup body 3, the outer cup sleeve 4 can insulate against the heat and prevent the user from being scalded. The outer cup sleeve 4 can only rotate and cannot move up and down. In winter, if... Figure 6 Disposable cups need to have good heat retention properties. In this case, the disposable cup is in an insulated state, and the outer cup sleeve 4 encloses the groove 5, forming a closed first heat-retaining cavity, reducing heat loss and improving heat retention performance; in summer, such as... Figure 5 It does not require good heat preservation performance. When the outer cup sleeve 4 is rotated, the heat dissipation vent 6 coincides with the groove 5. The groove 5 is connected to the outside through the heat dissipation vent 6, which facilitates heat dissipation of the inner cup body 3 and reduces its heat preservation performance.

[0029] As one implementation method, the bottom of the inner cup body 3 has a double-layer structure, forming a second heat preservation cavity.

[0030] The above settings improve the heat retention performance of the bottom of the disposable cup.

[0031] Specifically, the inner cup body 3 of this application includes a trumpet-shaped cup wall that is larger at the top and smaller at the bottom, and two circular base plates fixedly connected to the inner side of the lower end of the cup wall. The two base plates and the cup wall form a closed second heat-insulating cavity, which improves the heat-insulating performance of the bottom of the cup. In addition, the lower end of the cup wall protrudes from the lower side of the base plate, and the thickness of the lowest side of the cup wall is reduced to reduce the contact area with the table and further improve the heat-insulating performance.

[0032] As one implementation method, the lower end of the inner cup body 3 is fixedly connected to the limiting rib 7 along the outer periphery, and the lower end of the outer cup sleeve 4 abuts against the limiting rib 7.

[0033] The above settings prevent the outer cup sleeve 4 from slipping down.

[0034] As one implementation method, a conical surface 8 is provided on the lower side of the limiting rib 7. The lower end of the conical surface 8 is inclined inward and extends to the outer wall of the inner cup body 3. The height h of the limiting rib 7 is less than or equal to 2mm.

[0035] The above settings make it easy to attach the outer cup sleeve 4 upwards.

[0036] The outer cup sleeve 4 is made of plastic and has good elasticity. The conical surface 8 of the limiting rib 7 plays a guiding role. When the outer cup sleeve 4 is put on upward, the conical surface 8 can open the outer cup sleeve 4. The outer cup sleeve 4 deforms elastically. After the lower end of the outer cup sleeve 4 passes the limiting rib 7, the outer cup sleeve 4 rebounds and fits the inner cup body 3. The lower end of the outer cup sleeve 4 abuts against the upper side of the limiting rib 7, and the limiting rib 7 prevents the outer cup sleeve 4 from sliding down.

[0037] As one implementation method, the rim of the inner cup body 3 is folded outward to form a reinforcing rib 9.

[0038] The above settings enhance the rigidity of the cup opening of the inner cup body 3, preventing deformation of the cup opening when drinking water.

[0039] As one implementation method, the groove 5 is rectangular and extends vertically. Multiple grooves 5 are provided in both the vertical and circumferential directions. The distance between two adjacent grooves 5 is equal to the length of the groove 5. The ratio of the distance between two adjacent grooves 5 in the circumferential direction to the width of the groove 5 is between 3 and 5.

[0040] The grooves 5 in this application are arranged in multiple rows and columns, with each row of grooves 5 evenly arranged along the circumference. In this application, there are 15 grooves 5 in each row and 5 grooves 5 in each column.

[0041] As one implementation method, the inner cup 3 is a frustum structure that is larger at the top and smaller at the bottom.

[0042] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
