Description

Technical Field

[0001] This utility model belongs to the field of cup lid technology, specifically relating to a spout cup lid that combines disassembly and sealing. Background Technology

[0002] Most existing sippy cup lids use a direct snap-fit ​​method between the spout and the lid body to facilitate spout removal. While a strong snap-fit ​​ensures a reliable seal, it makes disassembly difficult. Conversely, a weak snap-fit, while easy to disassemble, compromises the seal (especially when the pressure inside the cup is high, as the pressure from the cup and the sealing ring act simultaneously on the spout). Adding other structures instead of a direct snap-fit ​​allows for reliable sealing and easy disassembly, but results in a more complex structure.

[0003] Therefore, it is of practical significance to provide a spout cup lid that is both easy to disassemble and reliably sealed. Utility Model Content

[0004] This invention addresses the shortcomings of existing detachable spout cup caps, which fail to balance ease of disassembly and reliable sealing. It provides a spout cup cap that balances both disassembly and sealing, making it easy to disassemble and reliably sealed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spout cup lid that combines disassembly and sealing, wherein the spout cup lid that combines disassembly and sealing includes:

[0006] The cover has a receiving groove, the bottom wall of which has a water outlet and an air inlet, and the side wall of which has an L-shaped groove, which includes a vertical section and a horizontal section. The bottom wall of the horizontal section of the L-shaped groove extends to form a snap-fit ​​protrusion.

[0007] The water outlet sealing ring is located in the water outlet hole and has a water outlet channel;

[0008] The intake sealing ring is located in the intake hole and has an intake channel;

[0009] The nozzle is located in the receiving groove and swings relative to the cover. The nozzle has a water outlet sealing part, an air inlet sealing part and a drinking part, and a drinking channel is formed in the water outlet sealing part and the drinking part.

[0010] The water outlet sealing part of the suction nozzle extends to form a swinging protrusion located in the L-shaped groove. The outer end face of the swinging protrusion is provided with a snap-fit ​​hole, and the snap-fit ​​protrusion is located in the snap-fit ​​hole. The swinging protrusion of the suction nozzle and the transverse section of the L-shaped groove are matched.

[0011] This invention provides a spout cup lid that combines disassembly and sealing. The side wall of the lid's receiving groove has an L-shaped groove, comprising a vertical section and a horizontal section. The swinging protrusion of the spout engages with the horizontal section of the L-shaped groove. The groove wall of the horizontal section of the L-shaped groove restricts the swinging protrusion of the spout, preventing vertical movement of the spout. The spout can reliably compress the sealing ring without detaching from the lid, thus ensuring a seal. Compared to existing technologies that rely on a protrusion extending from the side wall of the L-shaped groove to engage with the swinging protrusion of the spout, this invention uses a locking hole on the outer end face of the swinging protrusion. The bottom wall of the horizontal section of the L-shaped groove extends to form a locking protrusion located in the locking hole. The bottom wall of the L-shaped groove and / or the locking protrusion with the locking hole are more easily deformed, making disassembly and assembly easier.

[0012] As an improvement, the snap-fit ​​protrusion is spherical.

[0013] As an improvement, the snap-fit ​​hole includes a chamfered section at the outer end and a round hole section at the inner end.

[0014] As an improvement, the inner end of the transverse section of the L-shaped groove is semi-circular, and the swinging protrusion of the nozzle is cylindrical.

[0015] As an improvement, the upper end of the vertical section of the L-shaped groove is flared.

[0016] As an improvement, the nozzle also has an operating section.

[0017] As an improvement, the water outlet sealing ring and the air inlet sealing ring are integrated into a single structure to form an integral sealing ring. The integral sealing ring is installed from top to bottom, with a water outlet anti-detachment protrusion at the lower end of the water outlet sealing ring and an air inlet anti-detachment protrusion at the lower end of the air inlet sealing ring.

[0018] As an improvement, the inner side of the water outlet hole extends to form a water outlet protrusion ring, and the water outlet sealing ring forms a water outlet annular groove that mates with the water outlet protrusion ring; and / or,

[0019] The inner side of the air intake hole extends to form an air intake convex ring, and the air intake sealing ring forms an air intake ring groove that mates with the air intake convex ring.

[0020] As an improvement, the inner side of the water outlet channel of the water outlet sealing ring extends to form multiple annular ribs.

[0021] As an improvement, the water outlet sealing part is cylindrical, and the water outlet sealing part compresses the water outlet sealing ring from top to bottom, with the upper end of the water outlet sealing ring matching the shape of the water outlet sealing part; and / or,

[0022] The intake seal is cylindrical and is inserted into the intake channel.

[0023] The beneficial effects of this invention's spout cup lid, which combines disassembly and sealing, are as follows: An L-shaped groove is formed on the side wall of the lid's receiving groove. The L-shaped groove includes a vertical section and a horizontal section. The swinging protrusion of the spout cooperates with the horizontal section of the L-shaped groove. The groove wall of the horizontal section of the L-shaped groove restricts the swinging protrusion of the spout, preventing the vertical movement of the spout. The spout can reliably compress the sealing ring without detaching from the lid, thus ensuring a seal. A snap-fit ​​hole is formed on the outer end face of the swinging protrusion. The bottom wall of the horizontal section of the L-shaped groove extends to form a snap-fit ​​protrusion, which is located in the snap-fit ​​hole. The bottom wall of the L-shaped groove and / or the snap-fit ​​protrusion with the snap-fit ​​hole are more easily deformed, making disassembly and assembly easier. Attached Figure Description

The swinging protrusion 46 of the suction nozzle 4 and the transverse section 142 of the L-shaped groove 14 cooperate with each other.

[0052] In this embodiment, the bottom wall of the L-shaped groove 14 is relatively thin, which is conducive to the deformation of the L-shaped groove 14 and makes it easier for the suction nozzle 4 to enter and exit.

[0053] See Figure 5 In this embodiment, the snap-fit ​​protrusion 15 is spherical. The snap-fit ​​protrusion 15 is slightly raised. Compared with the columnar protrusion, the spherical snap-fit ​​protrusion 15 makes it easier for the suction nozzle 4 to enter and exit, thus making disassembly and assembly easier.

[0054] In this embodiment, the snap-fit ​​hole 47 includes a chamfered section 471 at the outer end and an inner circular hole section 472. The inner circular hole section 472 makes it easier for the swinging protrusion 46 of the suction nozzle 4 to deform, making it easier for the suction nozzle 4 to enter and exit.

[0055] In this embodiment, the inner end of the transverse section 142 of the L-shaped groove 14 is semi-circular, and the swing protrusion 46 of the suction nozzle 4 is cylindrical.

[0056] In this embodiment, the upper end of the vertical section 141 of the L-shaped groove 14 is flared to facilitate the suction nozzle 4 entering the L-shaped groove 14.

[0057] In this embodiment, the suction nozzle 4 also has an operation part 44.

[0058] In this embodiment, the water outlet sealing ring 2 and the air inlet sealing ring 3 are an integral structure forming a one-piece sealing ring.

[0064] In this embodiment, a limiting protrusion 16 is also formed on the cover 1, and a limiting groove 32 is opened on the air intake sealing ring 3. The limiting protrusion 16 is inserted into the limiting groove 32 to further reduce the movement of the air intake sealing ring 3.

[0065] The beneficial effects of the spout cup lid of Embodiment 1 of this utility model, which combines disassembly and sealing, are as follows: An L-shaped groove 14 is formed on the side wall of the receiving groove 11 of the lid body 1. The L-shaped groove 14 includes a vertical section 141 and a horizontal section 142. The swinging protrusion 46 of the spout 4 cooperates with the horizontal section 142 of the L-shaped groove 14. The groove wall of the horizontal section 142 of the L-shaped groove 14 restricts the swinging protrusion 46 of the spout 4, preventing the vertical movement of the spout 4. The spout 4 can reliably compress the sealing ring without detaching from the lid body 1, thereby ensuring a seal. A snap-fit ​​hole 47 is formed on the outer end face of the swinging protrusion 46, and the bottom of the horizontal section 142 of the L-shaped groove 14... The wall extends to form a snap-fit ​​protrusion 15, which is located in the snap-fit ​​hole 47. The bottom wall of the L-shaped groove 14 is thinner and easier to deform. The snap-fit ​​protrusion 15 has a snap-fit ​​hole 47, and it is also easier to deform, making it easier to assemble and disassemble the nozzle 4. The snap-fit ​​protrusion 15 is spherical and slightly protrudes (the protrusion height is low), requiring less deformation, which is beneficial for the snap-fit ​​protrusion 15 to enter and exit the snap-fit ​​groove of the nozzle 4. The water outlet sealing ring 2 and the air inlet sealing ring 3 adopt an integrated structure, which is less likely to shift. The upper shape of the water outlet sealing ring 2 is adapted to the water outlet sealing part 41 of the nozzle 4 to ensure a seal.
