Description

Technical Field

[0001] This utility model belongs to the field of beverage packaging, specifically relating to a leak-proof direct-drinking cup lid. Background Technology

[0002] Leak-proof drinking cup lids are lids designed for use with disposable cups for cold drinks such as milk tea and juice, and are designed to prevent spills and splashes from takeout beverages.

[0003] Regarding the direct-drinking cup lid mentioned in patent number CN202010464391, its cut is completely penetrating, the cut has no connection point for fixation, and there is no obvious anti-spillage effect. In addition, its stopper is not locked into the groove, which makes it easy to pop out and affect the drinking experience. Furthermore, the edge of the lid and the stopper have no rib structure for reinforcement, and they are very easy to collapse and deform during use.

[0004] Currently, the technical solution for this type of leak-proof direct-drinking cup lid involves etching linear grooves on the cutting anvil of the spout die. During the pressing process, the etched lines cannot be completely cut through, leaving tiny connection points at the corresponding positions of the spout cut. This maintains a certain degree of adhesion at the spout, achieving a certain leak-proof effect. However, because leak-proof lids require wide and densely spaced etched lines, there is a contradiction: the large number of connection points at the spout cut makes them difficult to open. Therefore, problems such as the spout being difficult to open or loose connections leading to spills often occur. Furthermore, these leak-proof direct-drinking cup lids frequently experience folding deformation and insecure fastening, rendering them unusable for drinking and resulting in a poor user experience.

[0005] Existing lid technologies cannot adequately meet practical usage needs, thus requiring a more effective leak-proof direct-drinking cup lid solution to address this issue. Summary of the Invention

[0006] Purpose of the invention: In order to solve the technical problems existing in the prior art, this utility model aims to provide a leak-proof direct drinking cup lid with anti-spillage effect, non-deformable rim, and spring-back design.

[0007] Technical solution: The leak-proof direct drinking cup lid of this utility model includes a lid surface, a drinking spout surface that is recessed on the lid surface and relative to the lid surface, a lid flange that is raised upward relative to the lid surface, a cup fitting ring around the lid flange, and a skirt around the cup fitting ring for cooperating with the cup spout. The drinking spout surface is provided with a flip-up protrusion and a flip-up buckle for fixing the flip-up protrusion. The flip-up protrusion forms a sealed connection with the drinking spout surface through a cutting line.

[0008] Furthermore, the side wall of the flip-top buckle is provided with a buckle groove, and the side wall of the flip-top protrusion is provided with a flip-top lock. The buckle groove and the flip-top lock form a snap-fit ​​structure. When the flip-top protrusion is flipped into the flip-top buckle, it can lock the flip-top protrusion back and prevent the cover from being squeezed and deformed.

[0009] Furthermore, the cutting line has connection points and a tiny, dense mesh-like adhesive structure to further enhance the leak-proof effect of the leak-proof drinking cup lid.

[0010] Furthermore, a bending groove with a hinge function is provided between the flip-out buckle and the flip-out boss.

[0011] Furthermore, the flip-top fastener is provided with a guide slope to facilitate the snapping of the flip-top boss. When the flip-top boss is flipped in, it can be guided into the flip-top fastener.

[0012] Furthermore, the front end of the flipped boss is provided with a front flipping rib, and the rear end is provided with a rear flipping rib, which can prevent the flipped boss from deforming and collapsing when it is flipped.

[0013] Furthermore, the skirt is evenly distributed with radially raised arc-shaped ribs that have a strength-enhancing function, which can improve the strength of the skirt and prevent the skirt from collapsing and deforming during the process of the cup lid being put into the cup.

[0014] Furthermore, the skirt is also provided with an outer straight edge, which can increase the surface area of ​​the cover edge and prevent fingers from being scratched during the opening process.

[0015] Furthermore, the cutting line is U-shaped. Depending on the material and specifications, the cutting line shape can be set to C-shaped, which can effectively reduce the rebound force and increase the ease of use.

[0016] Beneficial effects: Compared with the prior art, the present invention has the following advantages: The present invention provides a guide slope and a buckle groove at the folding opening, and a folding opening protrusion is provided with a folding opening lock, a front rib and a rear rib at the folding opening. When the folding opening protrusion is folded in, it can accurately enter the folding opening buckle without springback or deformation and collapse; the area on the cutting line other than the connection point is provided with a tiny and dense mesh-like adhesive structure, which can effectively ensure the stability and consistency of the cutting line of the drinking spout, and effectively solve the problem of the drinking spout being difficult to open or the connection point being loose and causing leakage in conventional products.
