Abstract
Description
Technical Field
[0001] The utility model relates to a leak-proof cup cover. Background Art
[0002] Common cup lids are one-piece or split. The cup lid body is provided with a direct drinking port, a straw insertion port, and a downward depression to form a liquid storage tank. Pressure relief holes are provided in the liquid storage tank, and corresponding plugging ports and exhaust holes are provided on the upper cover. The pressure relief holes and corresponding baffles of the cup lid body are provided as a pair, and the pressure relief holes and exhaust holes are provided on both sides of the baffle. When sealing the lid, especially for hot drinks, due to the large pressure difference between the inside and outside, the pressure relief holes release pressure slowly, which often leads to unstable sealing or sudden spurting of hot water vapor when the drinker opens the lid to drink, resulting in a poor experience.
[0003] In addition, the delivered beverage will be discharged through the pressure relief hole due to shaking. The baffle can only prevent the beverage from being discharged directly from the vent hole and cannot cooperate with the beverage overflowing from the pressure relief hole to flow back into the cup, so most of the overflowed beverage remains in the liquid storage tank. Utility Model Content
[0004] The present application provides a leak-proof cup lid, the purpose of which is to improve the defect of slow pressure release and the problem of poor reflux effect of beverage overflowing from the pressure release hole.

[0007] The periphery of the exhaust hole extends upwardly along the blocking bottom to form a peripheral edge, and when the upper cover body and the cover body are closed, the peripheral edge abuts against the first blocking piece.
[0008] A circle of first clamping strips is arranged on the inner side of the liquid storage tank, and a corresponding second clamping strip is arranged on the outer side of the blockage, and the first clamping strips are elastically clamped with the second clamping strips.
[0009] The exhaust hole is located on the triangular protrusion.
[0010] An elastic card interface or a card strip is provided at the abutment position between the triangular protrusion and the second blocking piece.
[0011] The diameter of the pressure relief hole is smaller than the diameter of the return hole.
[0012] Due to the adoption of the above technical solution, the leak-proof cup lid of the present application can accelerate air deflation and ensure smooth sealing; at the same time, the reflux effect is improved by the inclined bottom plate of the liquid storage tank, and the triangular raised slope is provided to facilitate the condensation and reflux of water vapor; the entire cup lid is breathable and does not leak liquid.

[0014] Figure 2 It is a cross-sectional view of the first embodiment of the present application when the upper cover body and the cover body are closed;
[0015] Figure 3 This is a schematic structural diagram of the second embodiment of the present application; DETAILED DESCRIPTION
[0016] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0017] First embodiment:
[0018] like Figure 1 , which is a schematic diagram of the structure of the first embodiment of the present application. The leakproof cup cover in this embodiment includes a cup cover body 1 and an upper cover body 2. The cup cover body 1 and the upper cover body 2 are connected as one piece in this embodiment, but are certainly not limited to the connected as one piece, and can be a split type.
[0019] Combination Figure 1 and Figure 2 As shown, the cup cover body 1 is provided with a downwardly recessed liquid storage tank 11. A first baffle 12, a second baffle 13, a pressure relief hole 14 and a reflux hole 15 are provided on the bottom edge of the liquid storage tank 11. The pressure relief hole 14 is located on the outside of the first baffle 12, and the reflux hole 15 is located on the inside of the second baffle 13. A gap is maintained between the first baffle 12 and the second baffle 13. Preferably, the centers of the first baffle 12, the second baffle 13, the pressure relief hole 14 and the reflux hole 15 are on the same straight line. Figure 2 As shown, the bottom plate 111 of the liquid storage tank 11 is a structure inclined toward the reflux hole 15 .
[0020] A plug 21 is provided on the lower surface of the upper cover body 2 corresponding to the liquid storage tank 11, and a vent 22 is provided in the plug 21. A peripheral edge 221 extends upward from the periphery of the vent 22 along the bottom of the plug. A triangular protrusion 23 is provided in the plug 21, and a slope 231 of the triangular protrusion 23 is relatively long. When the upper cover body 2 and the cover body 1 are closed, the vent 22 is located between the first baffle 12 and the second baffle 13, and the peripheral edge 221 of the vent 22 abuts against the first baffle 12; the triangular protrusion 23 abuts against the second baffle 13, and the longer slope of the triangular protrusion 23 forms a clamping angle greater than 90° with the second baffle 13.
[0021] The pressure relief hole 14 and the reflux hole 15 can simultaneously relieve pressure when the cover is closed, thereby improving the pressure relief effect. The reflux hole 15 is used as the main pressure relief hole and is used for the reflux of the liquid, so it is preferable that the diameter of the reflux hole 15 is larger than the diameter of the pressure relief hole 14. At the same time, the first baffle 12 and the second baffle 13 separate the pressure relief hole 14 from the reflux hole 15, protecting the exhaust hole between the first baffle 12 and the second baffle 13 to prevent leakage or water vapor from being directly ejected from the exhaust hole. The water vapor ejected from the reflux hole 15 condenses directly on the slope of the triangular protrusion and flows along the slope, dripping back into the reflux hole 15 at the junction with the second baffle 13. The design of the double pressure relief hole and the triangular protrusion slope can not only meet the demand for rapid pressure relief, but also avoid the excessive pressure between the upper cover body 2 and the cover body 1 and causing it to fall off due to rapid pressure relief.
[0022] The pressure relief hole 14 is located on the outer side of the first baffle 12, and the reflux hole 15 is located on the inner side of the second baffle 13. The pressure relief hole 14 and the reflux hole 15 are respectively located at the two ends of the liquid storage tank, so that at least one hole can be unobstructed in different usage situations. For example, when the cup body is tilted toward the pressure relief hole 14, the liquid will cover the pressure relief hole 14. At this time, the reflux hole 15, as the main pressure relief hole, can remain unobstructed and balance the pressure difference inside and outside the cup body. When the cup body is tilted toward the reflux hole 15, once the liquid covers the reflux hole 15, the pressure relief hole 14 can be used as the main hole for balancing the internal and external pressures. Therefore, the design of the two holes, the pressure relief hole 14 and the reflux hole 15, can not only accelerate the pressure relief, but also achieve the effect of balancing the pressure inside and outside the cup body in different usage scenarios.
[0023] In addition, a circle of first clamping strips may be provided on the inner side of the liquid storage tank 11, and a corresponding second clamping strip may be provided on the outer side of the plug 2, and the first clamping strip and the second clamping strip may be elastically clamped. Alternatively, an elastic clamping interface or a clamping strip may be provided at the abutment between the triangular protrusion and the second baffle to increase the stability of the combination of the entire cover body 1 and the upper cover body 2, so as to prevent separation due to excessive pressure release.
[0024] In summary, the structure of the present application can meet the needs of rapid pressure relief, while solving the problem of residual liquid in the liquid storage tank. The overall structure is breathable and leak-free, and the experience is good.
[0025] Embodiment 2:
[0026] See also Figure 3 The second embodiment of the present application is shown in FIG. 1 . In this embodiment, the cover body 3 and the upper cover body 4 are split structures. The liquid storage tank 31 of the cover body 3 is provided with a first baffle 32, a second baffle 33, a pressure relief hole 34 and a reflux hole 35.
[0027] Different from the first embodiment, the exhaust hole 41 in this embodiment is directly disposed on the triangular protrusion 42. When the upper cover 4 and the cover body 3 are closed, the exhaust hole 41 is still located between the first blocking piece 12 and the second blocking piece 13.
[0028] The above-described embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Equivalent changes and modifications made to the present invention by those skilled in the art should all fall within the scope of the claims attached to the present invention.
