Description

Technical Field

[0001] This utility model relates to plastic cups, and more specifically to a composite plastic cup. Background Technology

[0002] Currently, most common plastic cups on the market adopt a one-piece molding design, with a fixed capacity. In actual use, users often face many inconveniences when they need to temporarily increase the capacity. If many guests visit and need to be served drinks, the existing single plastic cup cannot meet the capacity requirements, and purchasing additional large-capacity cups is difficult to meet the diverse usage scenarios. It is clear that the current plastic cup technology has significant shortcomings in terms of conveniently increasing capacity. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a combination plastic cup, the advantage of which is that this utility model can easily increase the capacity.

[0021] like Figure 1 As shown;

[0022] The composite plastic cup includes a cup body 1, an inner conical surface 2 is provided on the upper inner side of the cup body 1, and an outer conical surface 3 is provided on the lower outer side of the extended cylinder 4. The inner conical surface 2 of the cup body 1 and the outer conical surface 3 of the extended cylinder 4 are interference fit.

[0023] When a user needs to increase the capacity of a plastic cup, they pick up the extension tube 4 and align it with the opening of the cup body 1. Because the inner conical surface 2 on the upper inner side of the cup body 1 and the outer conical surface 3 on the lower outer side of the extension tube 4 have complementary tapers, the extension tube 4 is slowly pressed down until the two conical surfaces begin to contact. As the extension tube 4 is pushed further in, the outer conical surface 3 and the inner conical surface 2 fit tightly together under the interference fit, generating significant friction. This allows the extension tube 4 to be securely mounted on the cup body 1, effectively increasing the overall capacity of the cup and meeting the need to hold more liquid.

[0024] When the user no longer needs the large-capacity cup, they can simply grasp the extension tube 4 and apply upward force to overcome the friction between the conical surfaces, thus detaching the extension tube 4 from the cup body 1. This design, which achieves capacity increase or decrease through the interference fit of the conical surfaces, allows the modular plastic cup to be flexibly expanded when needed.

[0025] like Figure 2 As shown;

[0026] Because a sealing ring groove 5 is provided on the outer conical surface 3, and a sealing ring is fitted on the sealing ring groove 5;

[0027] When a user needs to increase the capacity of a plastic cup, they lift the extension tube 4, which is fitted with a sealing ring. The sealing ring fits tightly into the sealing ring groove 5 on the outer conical surface 3 of the extension tube 4. Aligning it with the opening of the cup body 1, the extension tube 4 is slowly pressed down because the inner conical surface 2 on the upper inner side of the cup body 1 and the outer conical surface 3 on the lower outer side of the extension tube 4 have complementary tapers. The two conical surfaces begin to contact. As the extension tube 4 is pushed further in, the outer conical surface 3 and the inner conical surface 2 fit tightly together, and the sealing ring undergoes elastic deformation under pressure, filling any tiny gaps that may exist at the conical surface fit. Under the combined action of the interference fit and the sealing ring, a large frictional force and sealing effect are generated, allowing the extension tube 4 to be securely installed on the cup body 1. This not only effectively increases the overall capacity of the cup but also ensures that there is no leakage when liquid is contained.

[0028] like Figure 2 As shown;

[0029] Because the cup body 1 has a fixed ring 8 integrally formed on it, the rubber ring 7 is hung on the fixed ring 8. The extended tube 4 has a hook 6 integrally formed on the cup body 1, and the upper part of the rubber ring 7 can be hung on the hook 6. When the cup body 1 and the extended tube 4 are connected, the rubber ring 7 is stretched so that the rubber ring 7 is hung on the hook 6. Then the rubber ring 7 is released. The rubber ring 7 always pulls the hook 6 through its elasticity, thereby preventing the cup body 1 and the extended tube 4 from easily separating.

[0030] like Figure 2 As shown;

[0031] The upper opening width of hook 6 is smaller than the lower opening width, so that the rubber ring 7 will not easily fall off when it is hung on hook 6, thus ensuring the stability of the rubber ring 7 hanging on hook 6.

[0032] like Figure 3 As shown;

[0033] The extended tube 4 has a flow channel 9 on its inner circumference. When the user drinks from the plastic cup, they can align the mouth with the flow channel 9 to drink. The flow channel 9 guides the liquid, making it easier for the liquid to enter the mouth and providing a better drinking experience.

[0034] like Figure 3 As shown;

[0035] Because the extended tube 4 has a partition 11 inside, with multiple circular perforations 10 on the partition 11, when the user wants to drink tea, they can pour tea leaves into the cup body 1 and then attach the extended tube 4 to the cup body 1. At this time, the partition 11 inside the extended tube 4 plays a crucial role; the multiple circular perforations 10 on the partition 11 allow for the separation of tea and water. After hot water is poured into the cup body 1, the hot water permeates the tea leaves through the perforations 10, releasing the aroma and flavor of the tea leaves in the cup body 1. The partition 11 prevents the tea leaves from passing through, while the tea water can rise through the perforations 10 into the extended tube 4, so the user drinks only the tea soup, avoiding the inconvenience of tea leaves entering the mouth.

[0036] like Figure 4 As shown;

[0037] The lower inner side of the extended cylinder 4 has a flat rod 13 integrally formed, which is located below the partition 11. The partition 11 is detachably connected inside the extended cylinder 4, and a rotating head 12 is integrally formed in the upper center of the partition 11. The flat rod 13 blocks the partition 11, limiting its position after contact. When the partition 11 is no longer needed for filtering tea, it can be removed. The rotating head 12 allows for easy manual removal of the partition 11.

[0038] like Figure 4 As shown;

[0039] Since the lower center of the partition 11 has an integrally formed threaded post 14, and the center of the flat rod 13 has a threaded hole, the threaded post 14 is threadedly connected to the threaded hole. Rotating the screw head 12 will rotate the partition 11 and the threaded post 14, causing the threaded post 14 to screw onto the flat rod 13, thus completing the installation of the partition 11. Disassembly only requires rotating the screw head 12 in the opposite direction to unscrew the threaded post 14 from the flat rod 13.

[0040] like Figure 5 As shown;

[0041] Since the partition 11 has an integrally formed insert post 15 on its lower center and the flat rod 13 has an insertion hole in its center, the insert post 15 is inserted into the insertion hole with an interference fit. The insert post 15 can be easily inserted into or removed from the flat rod 13, thereby completing the installation and removal of the partition 11.
