Description
Technical Field
[0001] This utility model relates to the field of cup lids, and in particular to a partitioned, one-piece folding cup lid that combines an anti-spillage and backflow cavity, a drinking spout, and a straw hole. Background Technology
[0002] With the rise of the coffee / milk tea beverage market, competition among brands is fierce, especially as traditional coffee and milk tea brands expand into other product categories. To attract younger consumers, they are launching concept products such as coffee + fruit tea, leading to increasing demands on the functionality of cup lids and making multi-functional lids a pressing need.
[0003] While current cup lids on the market offer features like spill prevention and access to straw and drinking spouts, they cannot be used independently, impacting the overall user experience. For example, in traditional one-piece cup lids, the straw hole interferes with the drinking spout, leaving it open and unhygienic. Furthermore, the straw hole is often integrated with the spill prevention hole without separate compartments, meaning the straw hole can become contaminated with contents during drinking, further affecting the user experience.
[0004] Therefore, it is necessary to develop new types of cup lid products with independent partition design for the lid body to improve the overall user experience. Summary of the Invention
[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a partitioned, integrated, folding cup lid that combines an anti-spillage backflow cavity, a drinking spout, and a straw hole. By integrating the anti-spillage backflow cavity, drinking spout, and straw hole into the cup lid, and through the independent partitioned lid-on (lifting) structure design, the overall partitioned usage performance of the product is improved.
[0006] Technical Solution: This utility model relates to a partitioned, one-piece folding cup lid that integrates an anti-spillage backflow chamber, a drinking spout, and a straw hole. Its features include: a cup lid body with an anti-spillage backflow chamber, a backflow hole, a baffle plate, an integrated folding lid, a drinking spout, and a straw hole; the integrated folding lid has a vent hole, an anti-spillage backflow chamber cover, a drinking spout cover, a straw hole cover, a drinking spout folding point, and a straw hole folding point; the cup lid body has an integrated folding lid structure, an anti-spillage backflow chamber structure, and a drinking spout and straw hole structure; the drinking spout cover and straw hole cover on the integrated folding lid structure are connected by an anti-theft plate, serving as a warning against theft if opened during operation.
[0007] The anti-spillage backflow cavity, drinking spout hole, and straw hole of the cup lid body are three independent functional areas. The straw hole does not share space with the backflow hole and does not interfere with each other, which can help improve the anti-spillage effect.
[0008] The straw hole does not have a straw hole baffle, which effectively prevents the straw baffle from falling into the cup and causing foreign objects to be generated, affecting food hygiene, and preventing consumers from inhaling them, thus ensuring drinking safety. Furthermore, there are no strength requirements for the straw tip during use, eliminating the need for punctures, especially considering the rigidity requirements of biodegradable PLA straws.
[0009] The integrated folding lid structure includes a drinking spout lid, a straw hole lid, a drinking spout folding point, and a straw hole folding point or handle clearance groove located on the folding lid. It is formed integrally with the cup lid by thermoforming process and is used to seal the drinking spout and straw hole. The drinking spout lid is fixed to the cup lid by the drinking spout folding point and does not spring back. The straw hole lid is fixed to the cup lid by the straw hole folding point and does not spring back.
[0010] The anti-spillage backflow cavity structure includes a backflow hole, a vent hole, and a baffle, which are integrally formed with the cup lid through a thermoforming process to prevent liquid inside the cup from spilling directly out of the vent hole.
[0011] The anti-spillage backflow chamber cover, drinking spout cover, and straw hole cover are connected to the integrated folding cover via a three-section hinge structure. The drinking spout cover and straw hole cover can be used independently, making them simple to operate and easy to promote.
[0012] The straw hole cap is folded and fixed by the straw hole folding point, or by other concave and convex buckle fixing methods.
[0013] The straw hole cover has a raised structure for opening with fingers, or a recessed structure for avoiding fingers, to prevent the cup cover from interfering with the fingers and making it difficult to operate, thus affecting the user experience.
[0014] Principle: By integrating the anti-spill reflux chamber, drinking spout hole, and straw hole into the lid, and using an independently partitioned lid-opening structure, the overall performance of the product is improved. This design prevents unsightly beverage residue from sticking to the straw baffle due to spillage within the reflux chamber, and addresses the shortcomings of traditional anti-spill chamber / straw hole baffle structures that need to be easy for the straw to puncture while avoiding excessive gaps that could lead to poor spill prevention. It simultaneously solves the contradiction of needing to both prevent spillage and ensure the straw is easy to puncture.
[0015] Beneficial Effects: Compared with existing technologies, this utility model has the following significant advantages: The integrated design of the cup lid not only meets consumers' needs for separate and independent use of the straw hole and drinking hole, but also solves the problems of straw hole detachment and poor spill prevention, eliminating consumer concerns. Furthermore, it addresses the issues of using adhesive tape for sealing and sealing the drinking hole with a plug after installation. The product is pre-assembled at the factory, minimizing the workload for store staff who would otherwise have to manually attach the lid. The spill prevention structure also reduces tape usage, achieving cost reduction and promoting energy conservation and environmental protection. Moreover, this structure effectively protects the lid's appearance, the functional partitions are reliable and easy to operate, mold development and production costs are low, and the centralized functional areas reduce product weight, material costs, and ease of promotion.

Detailed Implementation
[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] like Figure 1 , Figure 2 , Figure 3The present invention relates to a partitioned, one-piece folding cup lid that combines a spill-proof backflow cavity, a drinking spout, and a straw hole. The lid body 100 comprises a lid body 100 and an integral folding cover 105 disposed on the lid body 100. The lid body 100 has a spill-proof backflow cavity structure, including a spill-proof backflow cavity 108, a backflow hole 102, a baffle 104, and a vent 103 on the integral folding cover 105. The lid body 100 also has a drinking spout and straw hole structure, including a drinking spout 106 and a straw hole 107. The cup lid body 100 is provided with an integrated folding lid structure, including an anti-spillage backflow cavity cover 108 on the integrated folding lid 105, a drinking spout cover 109 on the integrated folding lid 105, a straw hole cover 110 on the integrated folding lid 105, a drinking spout folding point 111 on the integrated folding lid 105, a straw hole folding point 112 on the integrated folding lid 105 or a handle clearance pit 113 on the cup lid body, and an anti-theft plate 114 between the drinking spout cover and the straw hole cover on the integrated folding lid.
[0022] The anti-spillage backflow cavity 101, the drinking spout 106, and the straw hole 107 on the cup lid body 100 are three independent functional areas that do not interfere with each other. Preferably, the straw hole 107 and the anti-spillage backflow cavity 101 are independently partitioned. Unlike the traditional structure where the straw hole and the anti-spillage backflow cavity are set together, the straw hole 107 does not need to be equipped with a traditional straw baffle. This can prevent the straw hole from being designed in the backflow cavity, which would cause the beverage to stick to the straw baffle due to beverage overflow, resulting in an unsightly appearance. It also avoids the drawback of the traditional anti-spillage cavity combined with the straw hole baffle structure, which must ensure that it is easy for the straw to puncture, but also avoids the disadvantage of poor anti-spillage effect caused by liquid spraying due to excessive gaps. At the same time, it solves the contradiction of balancing anti-spillage and easy straw puncture.
[0023] The anti-spillage and backflow structure includes a backflow hole 102 for backflow and a baffle 104 for blocking liquid from spraying out. The baffle 104 consists of two or more pieces arranged in a staggered manner, and is set on the bottom surface of the backflow cavity and is concentrically opposite to the vent hole 103. A baffle is set on the side of the vent hole 103 to reduce the liquid being carried out by air pressure. It is formed into the cup lid by thermoforming process and is used to prevent the liquid in the cup from directly spilling out from the vent hole, thus playing a role in water vapor separation.
[0024] The integrated folding lid structure includes a spill-proof backflow chamber lid 108, a drinking spout lid 109, and a straw hole lid 110. Preferably, these are connected to the integrated folding lid via a three-segment hinge structure, forming a single integrated structure. It is thermoformed integrally with the cup lid, sealing the spill-proof backflow chamber to create a sealed, breathable, and backflow-proof cavity. Simultaneously, the drinking spout lid and straw hole lid seal the drinking spout and straw hole. The drinking spout hinge point 111 and the straw hole hinge point 112 are located on the integrated folding lid 105. The drinking spout lid 109 is fixed to the cup lid via the drinking spout hinge point 111 to prevent springback, and the straw hole lid 110 is fixed to the cup lid via the straw hole hinge point 112 to prevent springback.
[0025] The method of using the partitioned, one-piece, folding cup lid of this utility model, which combines a spill-proof backflow chamber, a drinking spout, and a straw hole, is as follows:
[0026] When drinking through the drinking spout 106, the drinking spout cover 109 is opened by hand and folded onto the integrated folding cover 105 via the hinge structure. It is then fixed to the cup lid by the drinking spout folding point 111 and will not spring back, allowing for direct drinking.
[0027] When drinking through the straw hole 107, the straw hole cover 110 is opened by hand and folded onto the integrated folding cover 105 via the hinge structure. It is then fixed to the cup lid by the straw hole folding point 112 and will not spring back, allowing the straw to be inserted for drinking.
[0028] When it is necessary to open the drinking spout 106 or the straw hole 107, the anti-theft plate connection structure will be damaged. During the delivery process, the damage can be judged to serve as a warning.
