Description

Technical Field

[0001] The utility model relates to a cup cover, in particular to a one-piece leak-proof cup cover with a repeated buckling function. Background Art

[0002] At present, in the beverage market of tea, milk tea and coffee, consumers have an increasingly strong demand for take-out and delivery. For hot drinks such as milk tea and coffee, since the production temperature of the drinks is high, water vapor will inevitably be generated at high temperature, so breathable packaging is required, resulting in the problem of leakage from the air holes during use and delivery becoming more and more serious.

[0003] In the existing market, the cup types used for milk tea and coffee drinks, and the paper cups for hot drinks are mostly 90 mm and 80 mm in diameter. In this limited space, many leak-proof structures are limited by the size of the storage container and the folding of the drinking mouth sealing plug. The leak-proof space is too small and the leak-proof effect is not ideal. In addition, most of the drinking mouth sealing plugs on the market are two-point card slot type fixed drinking mouth sealing plugs. Consumers need to snap both ends of the drinking mouth sealing plug into place at the same time before they can be opened and fixed to the cup lid. For consumers, snapping is more troublesome, and the actual use experience is not good. It is easy to not snap into place and bounce back to the face when drinking. Utility Model Content

[0023] The technical solution of the utility model is further described below in conjunction with the accompanying drawings of the specification.

[0024] like Figure 1-8As shown, the one-piece leak-proof cup cover with repeated buckling function of the utility model comprises a cup cover body 1, a leak-proof component 3 folded and connected to the cup cover body 1; a sealing ring 5 is provided at the bottom of the outer side of the cup cover body 1; a drinking mouth 4 is provided at one end of the cup cover body 1, and a folding connection 6 is provided at the edge of the sealing ring 5 at the other end corresponding to the drinking mouth 4, and the cup cover body 1 and the leak-proof component 3 are connected through the folding connection 6 provided at the sealing ring 5 of the cup cover body 1. A leak-proof groove 2 is provided on the cover surface of the cup cover body 1, and the leak-proof component 3 is provided with a leak-proof cover 3.2 corresponding to the leak-proof groove 2.

[0025] One end of the leak-proof component 3 is provided with a drinking mouth sealing boss 3.4 for sealing the drinking mouth 4, and the leak-proof component 3 can be folded from one side of the drinking mouth 4 to the opposite side of the drinking mouth 4; a stopper 3.6 is provided at the end of the leak-proof component 3 opposite to the drinking mouth sealing boss 3.4, and a buckle 3.41 is provided at the edge of the drinking mouth sealing boss 3.4. The leak-proof cover 3.2 of the leak-proof component 3 and the drinking mouth sealing boss 3.4, and the leak-proof cover and the cup cover body are connected by a connecting strip, and the connecting strip 3.7 between the leak-proof cover and the drinking mouth sealing boss is provided with a folding line 3.5 for facilitating the folding of the leak-proof component from one side of the drinking mouth to the opposite side of the drinking mouth; a groove 2.7 for accommodating the connecting strip 3.7 is provided on the cover surface of the cup cover body. The buckle 3.41 is used to buckle on the stopper 3.6 when the leak-proof component 3 is folded along the folding line 3.5, so as to fix the drinking mouth sealing boss 3.4 to the end of the leak-proof component 3. The limit block 3.6 of this embodiment is a protrusion disposed at the end of the leak-proof component and facing upward, and the buckle part 3.41 is a drink mouth buckle provided at the edge of the drink mouth sealing boss 3.4, and the drink mouth buckle protrudes from the edge of the drink mouth 4. When in use, the drink mouth sealing boss 3.4 can be opened from the drink mouth 4 by the drink mouth buckle, flipped around the folding line 3.5, and the drink mouth buckle clamped by the protrusion, and the drink mouth sealing boss 3.4 is fixed to one end of the leak-proof component 3, so as to prevent the drink mouth sealing boss 3.4 from shaking and rebounding to the drink mouth 4 during use. If the drink mouth 4 needs to be sealed again, the drink mouth sealing boss 3.4 only needs to be taken out from the limit block 3.6 through the drink mouth buckle, flipped around the folding line 3.5, and the drink mouth sealing boss 3.4 is fixed and sealed in the drink mouth 4 again, so as to achieve the function of repeated sealing.

[0026] An inner vent hole 2.1 is provided inside the leakproof groove 2 near the bottom of the leakproof groove 2. In this embodiment, the bottom of the leakproof groove 2 has a slope and the inner vent hole 2.1 is provided on the lower side; a liquid main baffle 2.31 is provided inside the leakproof groove 2 with a gap between it and the edge of the leakproof groove 2, forming the first line of defense against liquid. A liquid sub-baffle A2.32 is provided inside the leakproof groove 2 on the side of the liquid main baffle 2.31 away from the inner vent hole 2.1; a liquid sub-baffle C3.31 is provided on the inner surface of the leakproof cover 3.2, which can be connected with the liquid sub-baffle A2.32 up and down when the leakproof cover 3.2 is covered with the leakproof groove 2, forming the second line of defense against liquid. A liquid sub-baffle B2.33 is provided inside the leakproof groove 2 on the side of the liquid sub-baffle A2.32 away from the liquid main baffle 2.31, forming the third line of defense against liquid. The leak-proof cover 3.2 is provided with an outer vent hole 3.1 offset from the inner vent hole 2.1. The main liquid baffle of this embodiment is an arc-shaped baffle, and the liquid auxiliary baffles A and B are both bent baffles. The liquid auxiliary baffles A2.32 and B2.33 form a prism structure, so that the outer vent hole 3.1 is inside the prism structure.

[0027] The leakproof cover 3.2 is provided with a sealing fixing ring 3.3 for sealing the leakproof groove 2. When the leakproof component 3 is turned and rotated onto the cup cover body 1 with the folded connection 6 as the rotation axis, the sealing fixing ring 3.3 and the drinking mouth sealing boss 3.4 will be fixed to the leakproof groove 2 and the drinking mouth 4 on the cover surface of the cup cover body 1 respectively, playing a role of sealing and fixing. This structure can conveniently and automatically fix and seal the leakproof component 3 on the cup cover body 1 through a mechanical device.

[0028] When the leak-proof component 3 is fixedly sealed on the cup cover body 1, the inner air hole 2.1 and the outer air hole 3.1 are misaligned, and the liquid main baffle 2.31 is located between the inner air hole 2.1 and the outer air hole 3.1. At the same time, the liquid sub-baffle A2.32 and the liquid sub-baffle C3.31 are connected up and down to form a complete baffle, and form a prism with the liquid sub-baffle B2.33 to protect the outer air hole 3.1 therein. At this time, the inside of the leak-proof groove 2 is a sealed space that can accommodate the water vapor formed in the packaged hot drink product and the liquid shaken out. The water vapor enters the leak-proof groove 2 through the inner air hole 2.1 and is discharged through the outer air hole 3.1 to maintain the air pressure in the cup. It is stable and will not cause the lid to fall off and leak due to excessive air pressure. At the same time, the liquid shaken out during the takeaway process enters the leak-proof groove 2 through the inner air hole 2.1, and is first blocked by the liquid main baffle 2.31, and then blocked by the prismatic leak-proof structure formed by the liquid sub-baffle A2.32, the liquid sub-baffle C3.31 and the liquid sub-baffle B2.33. It can not only prevent the liquid from flowing along the top to the outer air hole 3.1, but also block the liquid in multiple directions so that it will not leak to the surface of the cup cover body 1 through the outer air hole 3.1, but will flow back into the cup along the slope in the leak-proof groove 2 to the inner air hole 2.1 at the bottom of the groove, thereby preventing the drink from leaking during the takeaway.
