Description

Technical Field

[0001] This utility model relates to a cup lid for beverages, specifically a multifunctional cup lid structure. Background Technology

[0002] The existing cup lid has the following problems: Poor leak prevention at the straw insertion point: Without a pre-sealed structure, liquid is prone to leakage. Separating the vent and drinking spout: requires a separate vent valve, which is complex and costly; The lid is easy to fall off: the connection between the large lid and the cup, and the small lid and the large lid, is loose and they are easy to fall off when squeezed during carrying. If the lid is irregularly shaped, the alignment is complicated and affects portability. Utility Model Content

[0003] The purpose of this utility model is to provide a multifunctional cup lid structure, which adopts a collaborative design of continuous punching, elastic drinking spout, round small lid and locking connection, and solves the problems of leakage prevention, venting, connection stability and operation convenience.

[0004] To achieve the above objectives, the following technical solution is adopted: A multifunctional cup lid structure includes a cup lid body and a circular cap, characterized in that: the top of the cup lid body is provided with a downwardly recessed circular cavity, the bottom surface of the circular cavity forms a drinking area through a notched punching ring, the punching ring has two circumferentially symmetrically distributed notches, the two notches form two circumferentially symmetrically distributed connecting parts on the bottom surface of the circular cavity, the two connecting parts connect the drinking area and the bottom surface of the circular cavity as one unit, a breakable tooth line is also punched on the drinking area, the two connecting parts are symmetrically distributed with the breakable tooth line as the center; the circular cap has an annular recessed portion, the outer wall of the annular recessed portion is provided with a convex ring, and the inner wall of the circular cavity is provided with an annular groove, when the circular cap mates with the circular cavity, the convex ring and the annular groove are engaged or interference-fitted, and the circular cap has an exhaust hole on the inner side of the annular recessed portion.

[0005] The small round cap has a handle on one side, and a protrusion at the bottom of the handle.

[0006] The cup lid body has a fastening ring on its outer periphery, which forms an annular groove between the cup lid bodies. An annular flange extending downward is provided on the edge of the fastening ring, and several anti-detachment protrusions are provided circumferentially along the annular flange. The anti-detachment protrusions are positioned lower than the annular groove.

[0007] This invention features a punched slit between the circumference of the drinking area and the bottom surface of the circular cavity, providing venting. The punched slit utilizes the surface tension of the liquid to also prevent leakage. The drinking area is reinforced with a serrated edge that automatically breaks when a straw is inserted, creating two separate covers that easily pierce the straw. The circular cap and the circular cavity are secured by a convex ring and an annular groove, ensuring a more stable connection. One side of the circular cap has a handle with a raised section at the bottom, slightly higher than the upper surface of the lid, facilitating easy lifting and opening of the circular cap. The design features leak-proof operation, smooth venting, stable connection, and convenient operation. Attached Figure Description

Detailed Implementation

[0009] like Figure 1-5 As shown, a cup lid includes a lid body 1 and a small circular cap 2. The lid body 1 has a downwardly recessed circular cavity 11 at its top. The bottom surface of the circular cavity 11 forms a drinking area 3 through a notched punching ring 12. The punching ring 12 has two circumferentially symmetrically distributed notches, which form two circumferentially symmetrically distributed connecting parts 13 on the bottom surface of the circular cavity 11. The two connecting parts 13 connect the drinking area 3 and the bottom surface of the circular cavity 11 as one unit. A breakable tooth line 31 is also punched on the drinking area 3. The two connecting parts 13... The teeth 31 are symmetrically distributed around the center; the circular cap 2 has an annular recess 21, and a protruding ring 22 is provided on the outer wall of the annular recess 21. An annular groove 14 is provided on the inner wall of the circular cavity 11. When the circular cap 2 is engaged with the circular cavity 11, the protruding ring 22 and the annular groove 14 are engaged or interference-fitted. The circular cap 2 has an exhaust hole 23 on the inner side of the annular recess 21; a lifting lug 24 is provided on one side of the circular cap 2, and a protrusion 25 is provided at the bottom of the lifting lug 24.

[0010] The cup lid body 1 has a fastening ring 15 on its periphery. The fastening ring 15 forms an annular groove 16 between the cup lid bodies 1. An annular flange 17 extending downward is provided on the edge of the fastening ring 15. Several anti-detachment protrusions 18 are provided on the annular flange 17 in the circumferential direction. The anti-detachment protrusions 18 are positioned lower than the annular groove 16.

[0011] This invention uses a punching ring 12 to punch out a drinking area 3 on the bottom surface of a circular cavity 11. The drinking area 3 is connected to the cup lid body 1 by a circumferential connecting part 13. When no straw is inserted, the gap in the punching ring 12 has an air venting effect. When the internal air pressure of the cup increases (e.g., 60℃ hot water, air pressure ≈ 0.03MPa), the drinking area is slightly tilted upward by an elastic sheet, and a tiny gap is created at the punching ring 12, from which gas is discharged to avoid splashing. At the same time, the surface tension of the liquid makes the punching gap smaller and also has a leak-proof effect. When a straw is inserted, the toothed line 31 is easy to break and can easily puncture the drinking area 3 to form a channel.

[0012] Both the small round cover and the round cavity are round. The small round cover can be closed by blind buckling with the handle. There is a vent hole at the top, which can continuously vent after being closed. The outer wall of the small round cover has an annular protrusion that can engage with the annular groove 14 on the inner wall of the round cavity 11. The axial displacement is small when vibrating or being squeezed, thus avoiding loss.

[0013] The annular flange 17 on the outer edge of the cup lid has several deepened anti-detachment protrusions 18 along its circumference. The anti-detachment protrusions 18 are positioned lower than the annular groove 16. When the cup lid is placed on, the anti-detachment protrusions 18 first slide over the outer side of the rolled edge of the cup body, and then the annular groove 16 engages with the inner side of the rolled edge, making it easier for the cup lid to be placed on. At this time, the anti-detachment protrusions 18 abut against the outer side of the lower edge of the rolled edge, and the annular groove 16 abuts against the inner side of the rolled edge. If the cup lid wants to detach from the rolled edge, the anti-detachment protrusions 18 must first pass through the outer side of the rolled edge. Since the annular groove 16 abuts against the inner side of the rolled edge, it is equivalent to increasing the strength of the cup lid flange, so that the anti-detachment protrusions 18 cannot expand and detach from the rolled edge of the cup body. This utility model has the characteristics of smooth air venting, stable connection, leak-proof and anti-detachment, and convenient operation.
