TECHNICAL FIELD

[0001] The utility model relates to water container technical field, especially cup assembly and cup cover. BACKGROUND

[0002] Although the traditional disposable paper cup is light and low in cost, its waterproof performance is limited, and it is easy to soak after holding water for a long time, which affects the use effect. In order to improve this problem, some paper cup manufacturers add waterproof coating in the paper cup. Although the waterproof performance is improved to some extent, the safety of the coating material cannot be guaranteed, and it is not easy to degrade after use, which poses a potential threat to the environment.

[0003] Due to the limitations of paper cups, aluminum disposable cups have gradually appeared in the market. Aluminum cups have won the favor of consumers due to their excellent waterproof performance and high strength. More importantly, aluminum materials can be recycled, which greatly reduces environmental pollution.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] The utility model provides a cup assembly and a cup cover 2, such as Figures 1 to 6 As shown, the cup body 1 and the cup cover 2 are provided as a separate part. Both the cup body 1 and the cup cover 2 are made of aluminum. The two are sealed by a snap-fit ​​structure, which can effectively prevent the liquid in the cup body 1 from overflowing from the cup mouth.

[0032] like Figure 2 As shown, the cup body 1 has an upper opening 11. The edge of this upper opening has been specially processed, first folded outward and downward and then folded inward and upward, thereby integrally forming a retaining portion 12 with a circular cross-section. This retaining portion 12 not only strengthens the edge of the upper opening 11 of the cup body 1 but also allows for a secure fit with the cup lid 2. The outer diameter D1 of the cross-section of the retaining portion 12 ranges from 0.25 to 0.3 cm.

[0033] like Figures 3 to 6 As shown, the outer periphery of the cup cover 2 is first folded upward and outward and then downward, forming a U-shaped buckling portion 21 that protrudes axially upward and opens downward. The U-shaped buckling portion 21 can accommodate the limiting portion 12 on the cup body 1, and the outer wall of the limiting portion 12 and the inner wall of the U-shaped buckling portion 21 are in contact with each other to form a seal. Specifically, the inner wall of the U-shaped buckling portion 21 near the center has the same curvature as the outer wall of the limiting portion 12. When in contact with the two, the inner and outer walls can fit tightly together, thereby forming an effective airtight seal.

[0034] like Figure 6As shown, an extrusion portion 22 is also formed in the U-shaped buckle portion 21. The extrusion portion 22 is located on the inner wall of the side of the U-shaped buckle portion 21 away from the center. The width between the extrusion portion 22 and the inner wall on the other side of the U-shaped buckle portion 21 is smaller than the outer diameter of the limiting portion 12 to limit the limiting portion 12 from falling out of the U-shaped buckle portion 21.

[0035] When the cup lid 2 needs to be tightly closed, the cup lid 2 is placed on the opening 11 of the cup body 1, so that the U-shaped buckle portion 21 of the cup lid 2 is aligned with the limiting portion 12 of the cup body 1, and the cup lid 2 is pressed downward with force. Since the cup body and the cup lid are both made of aluminum material, they are relatively soft and deformable. Therefore, the extrusion portion 22 of the U-shaped buckle portion 21 is slightly deformed under the extrusion of the limiting portion 12, so that the limiting portion 12 can be embedded in the U-shaped buckle portion 21. After the limiting portion 12 is embedded, the extrusion portion 22 squeezes the limiting portion 12 under the action of the restoring force, so that the outer wall of the limiting portion 12 fits with the inner wall of the U-shaped buckle portion 21 to form a seal, while limiting the limiting portion 12 from falling out of the U-shaped buckle portion 21, maintaining a sealed state. Since the opening of the extrusion portion 22 is slightly smaller than the outer diameter of the limiting portion 12, the limiting portion 12 will not fall out of the U-shaped buckle portion 21 without strong external force, that is, the cup cover 2 will not be separated from the cup body 1, maintaining good sealing.

[0036] The outer side of the U-shaped buckle portion 21 of the cup cover 2 is first folded outward and upward and then inward and downward to form a reinforcing portion 23 with a ring-shaped cross-section. Compared with the design that exposes the sharp outer edge to the outside, the ring-shaped reinforcing portion 23 of this solution is designed to prevent the user from scratching their hands when using the cup, thereby improving the safety of use.

[0037] In order to enhance the anti-deformation strength of the cup cover 2, a plurality of annular reinforcing ribs 24 are provided on the surface of the cup cover 2. Figure 3 and Figure 4 As shown, these annular reinforcement ribs 24 are spaced and evenly spaced from the center of the cup lid 2 toward the periphery, forming a stable and aesthetically pleasing reinforcement structure. The cross-section of the annular reinforcement ribs 24 can be designed in a variety of shapes to meet different strength and aesthetic requirements, including but not limited to isosceles trapezoids and arcs. Among them, the isosceles trapezoid, with its wider bottom and narrower top design, can provide more stable support. Therefore, in the preferred embodiment, we have selected an isosceles trapezoid as the cross-sectional shape of the annular reinforcement ribs 24 to further ensure the structural stability and deformation resistance of the cup lid 2.

[0038] The annular reinforcement rib 24 can be formed by the lower surface of the cup cover 2 protruding upward, thus adding a layer of solid "armor" to the cup cover 2; or it can be formed by the upper surface of the cup cover 2 being recessed toward the lower surface, forming a "groove"-like structure, which can also effectively enhance the deformation resistance of the cup cover 2. Both designs can effectively improve the strength and durability of the cup cover 2, providing users with a more reliable user experience.

[0039] As a further improvement of the structure, Figure 3 As shown, the cup lid 2 has a drain hole 25 in the middle, allowing the liquid in the cup body 1 to be poured out through the drain hole 25, while also allowing the user to drink the beverage through a straw. The diameter D2 of the drain hole 25 ranges from 1.20-1.30 cm, adapting to straws of varying diameters on the market.

[0040] The cup lid 2 has a thickness W1 ranging from 0.03-0.04 cm. This range ensures that the cup lid 2 has sufficient strength and durability while remaining lightweight and easy to carry. Through precise thickness control, the cup lid 2 can effectively resist deformation and maintain structural stability without placing additional burden on the user, thereby improving the overall user experience.

[0041] The cup lid 2 provided in this embodiment has a diameter D3 of 9.264 cm, a thickness W1 of 0.035 cm, and a diameter D2 of the water outlet 25 of 1.25 cm. The width W2 from the top of the U-shaped fastening portion 21 to the bottom of the reinforcement portion 23 of the cup lid 2 is 0.485 cm.

These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0043] At the same time, the directions such as front, back, left, and right mentioned in this embodiment are only for reference and do not represent the directions in actual use. The above description is only a preferred embodiment of the present invention and does not limit the design of this case. Any equivalent changes made based on the key design of this case fall within the scope of protection of this case.
