Description

Technical Field

[0001] This utility model relates to a cup lid, specifically a press-type cup lid. Background Technology

[0002] The lid is an important part of a water bottle. Nowadays, most lids have a press mechanism for easy dispensing. Press lids are easy to operate and are especially suitable for sports, driving and other scenarios. No need to twist the lid, just press to dispense water. High-quality press lids have good sealing performance and are not easy to leak when inverted. They are also easy to carry. Some products even use a double-layer explosion-proof structure to improve safety. Compared with traditional screw or pull lids, press lids are more compact and easier to store and carry.

[0003] However, most of the current cup lids are made of plastic, which makes the rim of the cup difficult to clean and relatively easy for bacteria to grow. Some users have reported odor problems at the rim, which may be related to incomplete cleaning or the material. In addition, the tea strainer structure at the bottom of the current cup lids is mainly connected by a threaded structure or a snap-fit, which can easily cause stripping or disengagement over time. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a press-type cup lid.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a press-type cup lid, comprising a cylindrical cup lid body and a press component disposed within the cup lid body. The press component and the fixed part of the cup lid body are provided with multiple water outlets. The lower telescopic end of the press component is fixedly driven to drive a sealing cover plate for covering the lower water inlet of the cup lid body. The edge of the water outlet at the top of the cup lid body is covered with an annular metal cup mouth. The upper edge of the annular metal cup mouth is bent inward and downward in sequence, so that the bent part forms a funnel-shaped flow guiding structure. A limiting ring is fitted between the annular metal cup mouth and the edge of the water outlet at the top of the cup lid body. The lower outer wall of the limiting ring is fixedly connected to the bottom edge of the annular metal cup mouth. The top edge of the limiting ring is provided with an inwardly bent limiting edge, and the limiting edge is tightly attached to the outer wall of the water outlet at the top of the cup lid body.

[0006] Furthermore, a retaining rubber ring is fixed around the outer edge of the water inlet at the lower end of the cup lid body. The upper edge of the inverted cone-shaped tea canister is fitted around the retaining rubber ring through an interference fit. The inverted cone-shaped tea canister is provided with multiple evenly arranged long strip-shaped side permeable holes, and a central permeable hole is provided at the lower center tip of the tea canister.

[0007] Furthermore, a mechanical thermometer and hygrometer are installed on the top of the pressing component, and the temperature probe of the mechanical thermometer and hygrometer passes through the pressing component and the central water-permeable hole of the tea compartment.

[0008] Furthermore, the pressing assembly includes a component fixing sleeve fixed inside the upper part of the cup lid body and a guide sleeve fixed inside the component fixing sleeve. The inner side wall of the guide sleeve is provided with downward limiting helical teeth. A vertical rebound slide is provided every other limiting helical tooth. The supporting helical teeth on the periphery of the rotating disk mesh with the limiting helical teeth. A pressing disk located inside the guide sleeve is provided above the rotating disk. The limiting block fixed on the periphery of the pressing disk slides within the rebound slide. The conical teeth on the bottom edge of the pressing disk and the limiting block mesh with the supporting helical teeth on the periphery of the rotating disk. A lifting sleeve that vertically penetrates the center of the cup lid body is provided at the bottom of the rotating disk. The upper end of the lifting sleeve contacts the lower surface of the rotating disk. A rebound spring that makes it spring upward is sleeved on the periphery of the lifting sleeve. The sealing cover is fixed on the periphery of the lower end of the lifting sleeve.

[0009] Furthermore, a compression spring is fixed inside the upper edge of the sealing cover plate, which contacts the lower surface of the center of the cup lid body.

[0010] Furthermore, a sealing ring for the cup mouth is provided below the external threaded part of the cup lid body.

[0011] Furthermore, the upper edge of the component fixing sleeve and the guide sleeve is fitted with an annular metal retaining ring.

[0012] Furthermore, a sleeve sealing ring is embedded in the center of the cup lid body through the lifting sleeve.

[0013] Furthermore, a spring retaining ring is fixed to the upper end of the rebound spring and penetrated by the lifting sleeve. The inner edge of the spring retaining ring is fixedly connected to the groove structure on the outer side wall of the lifting sleeve through a retaining plate structure.

[0014] Furthermore, the annular metal cup mouth is formed by stamping titanium alloy.

[0015] This invention features an inwardly bent limiting edge that is tightly attached to the outer wall of the spout at the top of the lid body. This limiting edge forms a hook-like structure that is fixedly connected to the spout at the top of the lid body. This ensures that the annular metal cup mouth will not detach even if accidentally lifted during use. Therefore, the annular metal cup mouth is more firmly fixed to the plastic lid body, effectively preventing it from falling off. Compared to traditional plastic cup mouths, the annular metal cup mouth design is not only easier to clean but also healthier, safer, and more reliable to use.

[0016] In addition, the main body of the cup lid is secured to the inverted conical tea compartment by an interference fit of a clamping rubber ring. This means the outer diameter of the clamping rubber ring is larger than the inner diameter of the opening at the top of the tea compartment. The tea compartment is secured using the elasticity and friction of the clamping rubber ring. This not only makes it easy to remove the tea compartment quickly, but also allows for simple slip-on installation, as the elasticity and friction of the rubber provide a secure hold. The clamping rubber ring is fitted onto the lower part of the main body of the cup lid. When replacement is needed after extended use, it can be easily removed, requiring only the clamping rubber ring to be replaced, thus reducing maintenance costs. The inverted conical tea compartment features multiple evenly spaced elongated side perforations, with a central perforation at the bottom center. This allows tea to flow more easily down the inner wall of the conical shape, converging towards the center and preventing tea residue from remaining on the tea leaves and affecting the taste of subsequent brews.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The following is a detailed description of this embodiment with reference to the accompanying drawings:

[0026] This embodiment provides a press-type cup lid; please refer to the accompanying drawings in the instruction manual. Figure 1-5 .

[0027] like Figure 1-5 As shown, a press-type cup lid includes a cylindrical cup lid body 1 and a press component disposed within the cup lid body 1. Multiple water outlets are provided at the fixed portion of the press component and the cup lid body 1. A sealing cover 2 for covering the water inlet at the lower end of the press component is fixedly driven at the lower telescopic end of the press component. An annular metal cup mouth 3 covers the edge of the water outlet at the top of the cup lid body 1. The upper edge of the annular metal cup mouth 3 bends inward and downward sequentially, forming a funnel-shaped flow guide structure 4 at the bend, facilitating drinking. The annular metal cup mouth 3 and the cup... A limiting ring 5 is fitted between the top outlet edge of the lid body 1 and the bottom edge of the annular metal cup mouth 3. The lower outer wall of the limiting ring 5 is fixedly connected to the bottom edge of the annular metal cup mouth 3. The top edge of the limiting ring 5 is provided with an inwardly bent limiting edge 6, and the limiting edge 6 is tightly attached to the outer wall of the top outlet edge of the lid body 1. A cup mouth sealing ring 24 is provided below the external thread part of the lid body 1. The upper edge of the component fixing sleeve 12 and the guide sleeve 13 is fitted with an annular metal fixing ring 25. The annular metal cup mouth 3 is made of titanium alloy stamping.

[0028] The annular metal cup mouth 3 of this application is made of titanium alloy and has an optimized structure to avoid the problem of easy detachment caused by direct nesting. Due to the inward bending of the limiting baffle 6 of the limiting baffle ring 5, and the limiting baffle 6 being tightly attached to the outer wall of the water outlet edge at the top of the cup lid body 1, the limiting baffle 6 forms a barb-like structure that is fixedly connected to the water outlet at the top of the cup lid body 1. Therefore, even if the annular metal cup mouth 3 is accidentally picked up during use, it will not fall off after it is fixed. Thus, the annular metal cup mouth 3 is more firmly fixed to the plastic cup lid body, effectively preventing the annular metal cup mouth 3 from falling off. Compared with the traditional plastic cup mouth, the design of the annular metal cup mouth 3 is not only easier to clean, but also healthier, safer and more reliable to use.

[0029] To facilitate tea brewing, a retaining rubber ring 7 is fixed around the outer edge of the water inlet at the lower end of the cup lid body 1. The upper edge of the inverted conical tea container 8 is fitted around the retaining rubber ring 7 with an interference fit. The inverted conical tea container 8 is provided with multiple evenly arranged elongated side permeable holes 9. A central permeable hole 10 is provided at the lower center of the tea container 8. This makes it easier for tea water to flow down and towards the center along the inner side wall of the cone in the tea container 8, and better avoids tea water residue on the tea leaves after brewing, which would affect the taste of subsequent brews. To facilitate real-time monitoring of the water temperature in the cup, a mechanical thermometer and hygrometer 11 is provided on the top of the pressing component, and the temperature probe of the mechanical thermometer and hygrometer 11 passes through the pressing component and the central permeable hole 10 of the tea container 8.

[0030] The pressing assembly, like the pressing structure of pressing cup lids currently on the market, specifically includes: a component fixing sleeve 12 fixed inside the upper part of the cup lid body 1, and a guide sleeve 13 fixed inside the component fixing sleeve 12. The inner side wall of the guide sleeve 13 is provided with downward limiting helical teeth 14, and a vertical rebound slide 15 is provided every other limiting helical tooth 14. The supporting helical teeth 17 on the periphery of the rotating disk 16 mesh with the limiting helical teeth 14. A pressing disk 18 located inside the guide sleeve 13 is provided above the rotating disk 16. The limiting block 19 fixed on the periphery of the pressing disk 18 slides within the rebound slide 15. The conical teeth 20 on the bottom edge of the pressing disk 18 and the limiting block 19 and the supporting helical teeth 17 on the periphery of the rotating disk 16 mesh with each other. The inclined teeth 17 mesh with each other. The bottom of the rotating disk 16 is provided with a vertical lifting sleeve 21 that penetrates the center of the cup lid body 1. The upper end of the lifting sleeve 21 contacts the lower surface of the rotating disk 16. The outer periphery of the lifting sleeve 21 is fitted with a spring 22 that makes it spring upward. The sealing cover plate 2 is fixed on the outer periphery of the lower end of the lifting sleeve 21. The upper edge of the sealing cover plate 2 is fixed with a downward pressure spring 23 that contacts the lower surface of the center of the cup lid body 1. The lifting sleeve 21 penetrates the center of the cup lid body 1 and is embedded with a sleeve sealing ring 26. The upper end of the spring 22 is fixed with a spring fixing ring 27 that is penetrated by the lifting sleeve 21. The inner edge of the spring fixing ring 27 is fixedly connected to the groove structure of the outer side wall of the lifting sleeve 21 through a clamping plate structure.

[0031] The working principle of the pressing component is similar to that of pressing cup lids currently on the market. By continuously pressing the mechanical thermometer and hygrometer 11 and the pressing plate 18, the rotating plate 16 is pushed downward. When the supporting helical tooth 17 of the rotating plate 16 moves downward to the limiting helical tooth 14, the lower end of the limiting block 19 pushes the limiting helical tooth 14 to move unidirectionally. When the return spring 22 rebounds, it pushes the supporting helical tooth 17 into the limiting helical tooth 14 again. At this time, the lifting sleeve 21 moves downward, thereby opening the sealing cover 2, and water can then flow out. Pressing the mechanical thermometer and hygrometer 11 and the pressing plate 18 again, when the rotating plate 16 rotates and the supporting helical tooth 17 slides into the return slide 15, the lifting sleeve 21 is lifted upward under the elastic force of the return spring 22, and the sealing cover 2 covers the water inlet at the lower end of the cup lid body 1, thereby closing the water flow.

[0032] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
