Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and more specifically to a sealing pad for a cup. Background Art

[0002] Cups are containers that we use to hold liquids in our daily lives. Cups are usually cylindrical in shape with a height greater than the width, so that they are easy to hold and keep the temperature of the liquid, but there are also cups in square shapes. Some cups also have grips, handles, or additional functional structures such as anti-scalding and heat preservation. Cups are generally small in size, so people can easily pick them up with one hand, and the bottom of the cup is wide, so they can be placed stably on the table. The cup body is made of strong, water-insoluble materials such as glass, ceramics, plastics, and metals, and can safely hold a variety of edible liquids. In general, in order to prevent dust and foreign objects from falling into the cup, the cup mouth is often covered with a lid. When you need to drink, you can open the lid to drink. If you do not operate it properly, the liquid in the cup will spill out; if the cup is a thermos cup, the lid is completely unscrewed to drink water, and the heat preservation effect is poor; when the lid and the cup body are screwed together, it is not convenient for children to use. There are cups on the market that do not require the lid to be fully opened to drink water.

[0003] For example, the Chinese patent with the announcement number CN216569419U discloses a water cup, which is provided with a nozzle on the middle cover, and then the upper cover is buckled with the middle cover, and the sealing part of the upper cover seals the nozzle, and the water can be drunk through the nozzle after the upper cover is opened. The Chinese patent with the announcement number CN210540506U discloses a reverse press-opening water cup cover, which is provided with a water outlet on the cover body, and then the top cover is buckled with the cover body, and the sealing gasket on the top cover seals the water outlet, and the water can be drunk through the water outlet after the top cover is opened.

[0004] The above-mentioned gaskets are installed by opening a hole in the top cover and clamping the top of the gasket on the hole. This installation method of the gasket is unstable and the gasket will be separated from the hole. For example, after pouring hot water into a cup, the top cover covers the middle cover and leaves it for a while, the water temperature in the cup decreases, the air pressure in the cup decreases, and the gasket is sucked by the water outlet. If the top cover is directly pulled off, the gasket will be separated from the hole on the top cover, and the gasket will still be adsorbed on the water outlet when the top cover is pulled off.

[0030] like Figure 1-Figure 6 As shown, this embodiment provides a sealing gasket for a cup, which is arranged on a cup cover 3 corresponding to the drinking port of the cup, and its main function is to maintain the sealing of the cup and prevent liquid leakage. The cup sealing gasket of this embodiment does not need to open a hole on the cup cover 3 to fix the elastic gasket 1 on the cup cover 3. In this embodiment, the elastic gasket 1 is pressed on the cup cover 3 by the elastic pressing frame 2, and the elastic gasket 1 can be stably installed on the cup cover 3.

[0031] Specifically, it includes an elastic pad 1 and an elastic pressing frame 2, wherein the elastic pad 1 extends outward to form a mounting portion 11, the elastic pressing frame 2 is arranged at the periphery of the elastic pad 1, and the elastic pressing frame 2 extends inward to form a holding portion 21, the holding portion 21 of the elastic pressing frame 2 is held on the mounting portion 11 of the elastic pad 1, and the elastic pressing frame 2 is connected to the cup cover 3, so that the elastic pad 1 is mounted on the cup cover 3 and is limited in the elastic pressing frame 2. The mounting portion 11 formed by the elastic pad 1 extending outward is held under the holding portion 21 of the elastic pressing frame 2, and under the action of the elastic pressing frame 2, the elastic pad 1 can be stably mounted on the cup cover 3, preventing the elastic pad 1 from moving when subjected to external force, ensuring the sealing effect of the sealing pad, not only improving the sealing performance and durability of the cup, but also avoiding the traditional hole-opening installation method, providing great convenience for users.

[0032] The cup cover 3 is provided with a limiting structure, and the elastic pad 1 or the elastic pressure frame 2 is provided with a limiting groove 12 at the corresponding position of the limiting structure. The limiting structure is a plurality of fixing columns 31 formed by extending downward from the cup cover 3, and a certain interval is left between adjacent fixing columns 31. In one embodiment, as Figure 2 and Figure 3As shown, the mounting portion 11 is provided with a plurality of limiting grooves 12, the limiting grooves 12 correspond to the positions of the fixing columns 31, and the limiting grooves 12 are sleeved on the fixing columns 31. The cooperation between the limiting grooves 12 and the fixing columns 31 stably mounts the elastic pad 1 on the cup cover 3 to prevent the elastic pad 1 from moving due to external forces. Preferably, the height of the fixing columns 31 is less than the thickness of the mounting portion 11, and the height of the fixing columns 31 is greater than half the thickness of the mounting portion 11. The setting of this height can not only ensure that the mounting portion 11 is stably sleeved on the fixing columns 31 and does not separate from the fixing columns 31, but also when the mounting portion 11 is squeezed, the elastic pressing frame 2 has the opportunity to abut against the fixing columns 31. Specifically, when the elastic pressing frame 2 is pressed and held on the mounting portion 11, it can squeeze the mounting portion 11 until it abuts against the top surface of the fixing columns 31, further increasing the stability of the installation of the elastic pad 1.

[0033] like Figure 4 and Figure 5 As shown, in one embodiment, the elastic pressing frame 2 is provided with a plurality of limiting grooves 12, the limiting grooves 12 correspond to the positions of the fixing columns 31, and the limiting grooves 12 are sleeved on the fixing columns 31. The cooperation between the limiting grooves 12 and the fixing columns 31 stably mounts the elastic pressing frame 2 on the cup cover 3 to prevent the elastic pressing frame 2 from moving due to external forces. Preferably, the height of the fixing columns 31 is less than the thickness of the elastic pressing frame 2, and the height of the fixing columns 31 is greater than half the thickness of the elastic pressing frame 2. This height setting can not only ensure that the mounting portion 11 is stably sleeved on the fixing columns 31, but also does not separate from the fixing columns 31.

[0034] like Figure 2 and Figure 3 As shown, in one embodiment, the cup cover 3 and the elastic pressing frame 2 are both made of plastic, and the connection method of the elastic pressing frame 2 and the cup cover 3 can be ultrasonic fixing technology. The ultrasonic fixing connection method is not only easy to operate, but also can achieve watertightness and airtightness between the elastic pressing frame 2 and the cup cover 3. The use of ultrasonic fixing technology can avoid the inconvenience caused by the need to use auxiliary products for traditional sealing gaskets, can achieve efficient and clean welding, and simplify the installation process. Ultrasonic fixing is an efficient and precise connection method that uses high-frequency sound wave vibrations to quickly melt plastic materials and tightly combine them together.

[0035] The top surface of the elastic pressing frame 2 can be welded to the cup cover 3 , and the holding portion 21 formed by the inwardly extending side surface of the elastic pressing frame 2 can be held on the mounting portion 11 , thereby achieving stable installation of the elastic pad 1 .

[0036] The middle of the top surface of the elastic pressing frame 2 is recessed downward to form a groove 22, and a plurality of protrusions 23 are provided on the periphery of the top surface of the elastic pressing frame 2. The top surface of the elastic pressing frame 2 after the groove 22 is formed downward is welded to the cup cover 3 to reduce the difficulty of welding. During welding, the protrusions 23 on the periphery of the elastic pressing frame 2 melt to fix the elastic pressing frame 2 to the cup cover 3.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, the elastic pad 1 is provided with a first end 13 and a second end 14, the height of the first end 13 of the elastic pad 1 and the height of the second end 14 of the elastic pad 1 are both flush with the bottom surface of the elastic pressing frame 2, the height of the elastic pad 1 gradually increases from the first end 13 of the elastic pad 1 to the middle of the elastic pad 1, and the height of the elastic pad 1 gradually decreases from the middle of the elastic pad 1 to the second end 14 of the elastic pad 1. The elastic pad 1 is relatively low in height at the first end 13 and the second end 14, a slope is formed at the first end 13 of the elastic pad 1 and the middle of the elastic pad 1, and a slope is formed at the middle of the elastic pad 1 and the second end 14 of the elastic pad 1. In the process of moving to the water outlet, it is easier to slide in and out of the water outlet.

[0038] In one embodiment, the elastic pad 1 is made of silicone. As a high-quality elastic material, silicone has excellent elasticity and resilience. Compared with elastic pads 1 made of other materials, the resilience of silicone is superior, which means that during use, the silicone pad can better adapt to pressure changes and quickly return to its original state. More importantly, the silicone material has good durability. Even during long-term use, the elasticity of the silicone pad can remain stable and is not prone to deformation or fatigue. This means that after multiple openings and closings, the silicone pad can still maintain a good sealing effect and effectively prevent liquid leakage. In addition, silicone also has excellent high temperature resistance and corrosion resistance. This means that the silicone pad can maintain good performance and stability under various temperatures and environments. Whether it is a cold drink or a hot drink, whether it is an acidic or alkaline liquid, the silicone pad can provide reliable sealing protection. By selecting silicone, the sealing pad of this embodiment not only improves the sealing performance and durability, but also provides users with a more reliable and stable use experience.

[0039] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0040] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
