Description

Technical Field

[0001] This utility model relates to a cup lid and cup with a foldable straw, belonging to the field of thermos cup technology. Background Technology

[0002] A thermos flask is generally a container with a vacuum layer inside the body, made of materials such as ceramic, stainless steel, or titanium alloy. It has a sealed lid on top. The vacuum layer insulates the water or other liquid inside from the outside environment, thus achieving the purpose of keeping it hot or cold. Currently, there are many ways to open the lid of a thermos flask, such as screw-on, press-on, and flip-top opening. For example, Chinese patent document CN215820509U discloses a lid with a straw cover, such as... Figure 7 As shown, a receiving groove 213 for accommodating a straw 22 is provided on the horizontal plate portion 212. One end of the straw 22 is hinged to the shaft hole 213a on the side wall of the receiving groove 213 via a pivot 220. A through hole 214 is provided on the horizontal plate portion 212 and at the bottom of the receiving groove 213. One end of the straw 22 is a suction nozzle portion 221, and the other end is provided with a tube opening (not shown in the figure). When the suction nozzle portion 221 is tilted upward and protrudes from the receiving groove 213, the tube opening can communicate with the through hole 214. Because this structure requires forceful downward pressing to insert the rotating shaft 220 into the shaft hole 213a during straw 22 installation, the shaft 220 is prone to deformation or breakage due to excessive force. During use, the shaft 220 is also prone to loosening, causing leaks due to poor sealing between the spherical surface of the straw 22 and the rubber gasket at the edge of the through hole 214. Furthermore, the straw 22 is not easily disassembled and replaced after installation; forcibly pulling the straw 22 out of the shaft hole 213a can easily damage the edge of the shaft hole 213a. Therefore, it is necessary to improve the installation structure of the straw 22. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a cup lid and cup with a foldable straw, which has a novel straw mounting structure, making installation and disassembly convenient, and the parts are not easily damaged.

[0004] To achieve the above objectives, this utility model provides a foldable straw cup lid, comprising a body, a straw, and a top cover. The body includes a horizontal plate with a receiving groove for accommodating the straw. One end of the straw is hinged to the side wall of the receiving groove via a pivot. A through hole is provided on the horizontal plate at the bottom of the receiving groove. One end of the straw is a mouthpiece, and the other end has a tube opening. When the mouthpiece is tilted upward and protrudes from the receiving groove, the tube opening can communicate with the through hole. The top cover is located above the receiving groove and is hinged to the straw at one end, while the other end has a snap-fit ​​structure for securing it to the body. Two L-shaped grooves for the pivot to enter are provided opposite to each other on the side wall of the receiving groove. Each L-shaped groove includes a vertical section and a horizontal section connected to the lower end of the vertical section. The upper end of the vertical section extends to the top edge of the receiving groove, and an anti-detachment protrusion is provided on the side wall of the horizontal section.

[0005] The transverse segment is divided by the anti-detachment protrusion to form a first part located near the vertical segment and a second part located away from the vertical segment, the second part having an arcuate surface that mates with the outer wall of the pivot.

[0006] The anti-detachment protrusions have a tendency to gradually narrow from the bottom to the top.

[0007] The depth of the horizontal segment is greater than the depth of the vertical segment.

[0008] A transverse groove is also provided on the side wall of the receiving groove and below the transverse section.

[0009] A sealing ring is provided at the bottom of the receiving groove and around the through hole.

[0010] A spherical surface is provided at one end of the straw away from the mouthpiece, and the opening of the straw is located on the spherical surface; the axis of the rotating shaft passes through the center of the spherical surface.

[0011] The sealing ring has a spherical upper surface that mates with the spherical face.

[0012] An eave protruding from the spherical surface is provided at the end of the straw away from the mouthpiece, and a stop portion that cooperates with the eave is provided at the bottom of the receiving groove.

[0013] This utility model also provides a cup, including a cup body and a cup lid with a foldable straw as described above.

[0014] By adopting the above technical solution, the foldable straw cup lid and cup of this utility model have the following advantages compared with the prior art:

[0015] 1. The L-shaped groove structure replaces the traditional shaft hole. The shaft slides in through the vertical section and then moves laterally over the anti-detachment protrusion to complete the installation, eliminating the need for forceful pressing and reducing installation difficulty. Disassembly is performed by reversing the operation, avoiding damage to components caused by forced manipulation. The anti-detachment protrusion is designed in the horizontal section. Its narrowing slope guides the shaft to lock in place, preventing loosening and detachment, and facilitating sliding out during disassembly.

[0016] 2. The curved surface of the horizontal section fits against the outer wall of the rotating shaft, and with the limiting effect of the anti-detachment protrusion, it reduces the shaking of the straw and ensures that the spherical part of the straw end is in close contact with the sealing ring to prevent water leakage.

[0017] 3. The cooperation between the eaves and the stop further restricts the rotation angle of the straw and prevents excessive folding. Compared with the existing stop limiting structure, the parts are easier to process, the structure is more stable, and it is not easy to be damaged.

[0018] 4. The horizontal section of the L-shaped groove is deeper than the vertical section, making it less likely for the rotating shaft to come out when it enters the horizontal section; the added horizontal groove can provide a space for compression deformation for the lower side wall of the horizontal section, making it easier for the rotating shaft to be pushed over the anti-detachment protrusion.

[0019] 5. The spherical upper surface of the sealing ring matches the spherical face, improving the sealing effect and reducing wear from repeated opening and closing. Attached Figure Description

The L-shaped groove 24 includes a vertical section 241 and a horizontal section 242 connected to the lower end of the vertical section 241. The upper end of the vertical section 241 extends to the top edge of the receiving groove 213. An anti-detachment protrusion 243 is provided on the side wall of the horizontal section 242. The anti-detachment protrusion 243 has a tendency to gradually narrow from the bottom to the top.

[0031] The transverse segment 242 is divided by the anti-detachment protrusion 243 into a first portion 242a near the vertical segment 241 and a second portion 242b away from the vertical segment 241. The second portion 242b has an arcuate surface 242c that mates with the outer wall of the rotating shaft 220, thereby facilitating the stable rotation of the rotating shaft 220. The depth L1 of the transverse segment is greater than the depth L2 of the vertical segment. A transverse groove 25 is also provided on the side wall of the receiving groove 213 and below the transverse segment 242.

[0032] A sealing ring 26 is provided at the bottom of the receiving groove 213 and around the through hole 214. A spherical part 229 is provided at the end of the straw 22 away from the mouthpiece 221, and the opening 222 is formed on the spherical part 229; the axis of the rotating shaft 220 passes through the center of the spherical part 229. The sealing ring 26 is provided with a spherical upper surface that mates with the spherical part 229.

[0033] An eave 228 protruding from the spherical surface 229 is provided at one end of the straw 22 away from the mouthpiece 221, and a stop 27 that cooperates with the eave 228 is provided at the bottom of the receiving groove 213.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
