TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic shake cup, especially to the plastic shake cup with good protection performance. BACKGROUND
[0002] In today's era of increasing health awareness, as a kind of beverage that can be conveniently brewed, especially for people who often supplement protein powder and other decoctions, the shake cup plays an indispensable role. Its working principle is to assist the user in fully dissolving the decoction into water during the shaking process through the internal filter screen and the spring ball shaken up and down. Even in a low-temperature environment, uniform fusion can be achieved. This convenience makes it widely popular among fitness enthusiasts and people who pay attention to nutrition supplementation.
[0003] However, the common plastic shake cup on the market has exposed significant problems in actual use. Since it needs to be shaken vigorously during use to promote the mixing of the beverage, the user's hands are prone to accidental dropping of the shake cup due to uneven force, hand slipping, and other factors. From a material perspective, the plastic material itself is relatively brittle and has poor protection performance. When the shake cup falls, the cup body is easily damaged by impact, such as cracking and scratching. Once the cup body is damaged, the sealing performance is difficult to guarantee, leading to water leakage. Not only does this waste the beverage in the cup, but it also may affect the surrounding environment. If it happens in an office or fitness environment, it will also bring many inconveniences to the user. SUMMARY
[0004] To overcome the problem of the existing plastic shake cup, which is prone to damage and water leakage due to poor protection performance when it falls during use, the utility model provides a plastic shake cup with good protection performance.
[0005] The technical solution is as follows: the plastic shake cup with good protection performance includes a shake cup assembly, a sealing cover assembly, and a stainless steel stirring ball. The upper end of the shake cup assembly is provided with the sealing cover assembly. The inside of the shake cup assembly is provided with the stainless steel stirring ball. The shake cup assembly includes a cup body, an annular rubber ring filling, a reinforced steel ring, and an elastic rubber gasket. The sealing cover assembly includes a sealing cover, a sealing plug, and a rubber band.
[0006] Further, the inside of the cup wall of the cup body is provided with an annular rubber ring filling. The inside of the annular rubber ring filling is provided with a reinforced steel ring, and the annular rubber ring filling and the reinforced steel ring are placed in an injection mold and integrally injection molded with the cup body.
[0007] Further, the lower end of the cup body is provided with an elastic rubber gasket around it, and the elastic rubber gasket is placed in an injection mold and integrally injection molded with the cup body.
[0008] Furthermore, a sealing cap is provided at the upper end of the cup body, and the sealing cap is threadedly connected to the cup mouth of the cup body.
[0009] Furthermore, a sealing plug is provided at the upper outlet of the sealing cap, and the sealing plug is inserted into the interior of the upper outlet of the sealing cap for a sealing connection.
[0010] Furthermore, a rubber band is provided at the rear end of the sealing plug, and both ends of the rubber band are fixedly connected to the sealing plug and the sealing cap respectively, and the rubber band is elastic.
[0011] Furthermore, the stainless steel stirring ball is made of food-grade stainless steel and is shaped like a smooth sphere. It accelerates the dissolution of beverage powder by rolling freely inside the cup.
[0012] The beneficial effects are: This utility model improves the structural strength of the cup body by integrally injection molding the annular rubber ring filling and reinforcing steel ring inside the cup body and the cup wall, thereby improving the protective performance of the cup body and preventing the cup body from breaking. The reinforcing steel ring inside the annular rubber ring filling enhances the cup body's impact resistance.
[0013] By using elastic rubber gaskets, the cup body's lower end is made more resistant to impacts with the ground. Even if the lower outer shell of the cup body is broken by impact, the elastic rubber gaskets can still protect the integrity of the inner wall of the cup body and prevent leakage.
[0014] With its stainless steel stirring ball, the beverage, including protein powder, coffee, and milk tea, is highly hygienic. The ball rolls and bumps within the cup, breaking up clumps and accelerating powder dissolution, resulting in a smoother, more even drink and preventing undissolved particles. When the shaker is shaken, the stirring ball creates strong convection and vortexes, ensuring thorough mixing of ingredients—more effective than simply shaking by hand. Especially for thicker beverages, such as those containing dietary fiber or additives, the stirring ball effectively prevents sedimentation and separation, resulting in a more consistent taste. The smooth surface of the stainless steel stirring ball prevents dirt and bacteria buildup, making cleaning simple: just remove it, rinse with water, or wash it in a dishwasher.
