Description

Technical Field

[0001] This invention relates to the field of cup lid manufacturing technology, specifically a double-drinking cup lid. Background Technology

[0002] A dual-drinking cup generally refers to a cup that combines direct drinking and sipping functions. Users can choose the drinking method according to their personal preferences or usage needs.

[0003] One type of existing dual-drinking cup lid has separate drinking spouts and sippy spouts on the lid. Users select the appropriate drinking spout as needed. For example, a dual-drinking cup lid disclosed in patent application CN216822667U entitled "Dual-Drinking Cup Lid and Cup" includes a lid body and a drinking component. The lid body has a direct drinking spout and a sippy spout opposite each other. The drinking component includes a spout and a flip-top. The spout is hinged to the lid body and has a through-flow channel. Rotating the spout controls whether the sippy spout connects to or disconnects from the flow channel. The flip-top is hinged to the spout and is used to cover the spout and block the direct drinking spout. This type of dual-drinking cup lid essentially has two independent drinking structures on the lid, resulting in a complex structure.

[0004] Another type of existing dual-drinking cup lid uses a double-layered flip-top to switch between direct drinking and sipping functions. For example, patent application CN220001429U, entitled "A Dual-Drinking Cup Lid and Cup," discloses a dual-drinking cup lid that includes a connecting base for connecting the cup body, a first upper cover, and a second upper cover. The connecting base has a first horizontal plate portion, on which a drinking spout and a connecting tube are located. The lower end of the connecting tube is connected to a lower drinking tube. The first upper cover is hinged to the connecting base. The first upper cover has a second horizontal plate portion, on which an upper drinking tube is located. Because this type of dual-drinking cup lid uses a double-layered flip-top, it requires two corresponding snap-fit ​​structures, resulting in a complex structure and high manufacturing cost.

[0005] Therefore, the existing double-drink cup lid structure needs further improvement. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned deficiencies and to disclose to the public a dual-drinking cup lid with a reasonable structure and convenient use. In this dual-drinking cup lid structure, the drinking port is shared by both the sipping and direct drinking modes. The structure is compact and the switching between the direct drinking and sipping modes is convenient.

[0007] The technical solution of this invention is implemented as follows: A dual-drinking cup lid includes a lid body with a spout assembly. A connecting sleeve is fitted to the lower part of the spout assembly, and a straw is connected to the lower end of the connecting sleeve. The spout assembly includes a spout component and a switching component. The spout component has a drinking opening. The switching component drives the connecting sleeve to rise and fall by rotation. A sealing ring is provided between the upper end of the connecting sleeve and the lid body. In the drinking state, the upper end of the connecting sleeve is sealed to the lid body, and the inner cavity of the cup forms a drinking channel through the straw and spout component. In the direct drinking state, the upper end of the connecting sleeve separates from the lid body, forming a gap, and the inner cavity of the cup forms a direct drinking channel through the gap and spout component.

[0008] Further optimization measures for this technical solution are as follows: As an improvement, the specific structure of the switching component that drives the connecting sleeve to rise and fall by rotation is as follows: the switching component rotates and cooperates with the cup lid body; a driving protrusion is provided on the outer wall of the switching component; a spiral groove is provided on the inner wall of the connecting sleeve; the driving protrusion is placed in the spiral groove; a limiting protrusion is provided on the outer wall of the connecting sleeve; a lifting groove is vertically provided on the cup lid body; and the limiting protrusion is placed in the lifting groove.

[0009] As an improvement, the upper end of the spiral groove extends vertically upward to the upper end face of the connecting sleeve to form a disassembly groove. The connecting sleeve is designed as a detachable structure for easy cleaning.

[0010] As an improvement, the cup lid body includes an inner lid and an outer lid that are fixed together. A flip cover is hinged to the outer lid. A locking assembly is provided between the outer lid and the flip cover. The locking assembly includes an unlocking component that elastically engages with the outer lid. The unlocking component is provided with a locking hook. The flip cover is provided with a locking groove that matches the locking hook.

[0011] As an improvement, the unlocking component is provided with a limiting hook for preventing blowouts and relieving pressure.

[0012] As an improvement, the outer wall of the connecting sleeve is symmetrically provided with limiting protrusions on both sides, and correspondingly, there are two lifting grooves. The middle of the inner cover is provided with a partition with a notch, one of the lifting grooves is provided on the partition, and the other lifting groove is provided on the inner wall of the inner cover.

[0013] As an improvement, the inner cover is provided with a boss, and the boss has a vent hole. The outer cover is provided with a mounting hole that matches the boss. The flip cover is provided with a push rod that matches the vent hole, and the lower end of the push rod has a plug. When the flip cover is closed, the plug blocks the vent hole.

[0014] As an improvement, the upper end of the switching component is provided with a turntable, the turntable has a protrusion, the lower surface of the turntable has a positioning groove, and the inner cover has positioning protrusions that are adapted to the positioning groove and correspond to each state. The cooperation between the positioning groove and the positioning protrusions indicates that the switching component has rotated to the correct position (state switched to the correct position).

[0015] As an improvement, a reset spring is provided between the unlocking component and the outer cover, and limit buckles are provided on both sides of the unlocking component.

[0016] As an improvement, a sealing gasket adapted to the drinking spout is fixed on the flip cover. When the flip cover is closed, the sealing gasket blocks the drinking spout to ensure the sealing of the drinking spout in the closed state.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] like Figures 1 to 15 As shown, a dual-drinking cup lid includes a lid body 1, a spout assembly on the lid body 1, a connecting sleeve 2 externally fitted to the lower part of the spout assembly, a straw 3 connected to the lower end of the connecting sleeve 2, the spout assembly including a spout component 4 and a switching component 5, the spout component 4 having a drinking opening 4a, the switching component 5 driving the connecting sleeve 2 to rise and fall by rotation, a sealing ring 6 being provided between the upper end of the connecting sleeve 2 and the lid body 1; in the drinking state, the upper end of the connecting sleeve 2 is sealed to the lid body 1, and the inner cavity of the cup forms a drinking channel through the straw 3 and the spout component 4; in the direct drinking state, the upper end of the connecting sleeve 2 separates from the lid body 1 to form a gap 1a, and the inner cavity of the cup forms a direct drinking channel through the gap 1a and the spout component 4.

[0024] The specific structure of the switching component 5, which drives the connecting sleeve 2 to rise and fall by rotation, is as follows: the switching component 5 rotates and engages with the cup lid body 1; a driving protrusion 5a is provided on the outer wall of the switching component 5; a spiral groove 2a is provided on the inner wall of the connecting sleeve 2, and the driving protrusion 5a is placed within the spiral groove 2a; a limiting protrusion 21 is provided on the outer wall of the connecting sleeve 2; and a lifting groove 1b is vertically provided on the cup lid body 1, and the limiting protrusion 21 is placed within the lifting groove 1b. The switching component 5 is fitted onto the outside of the suction nozzle 4.

[0025] The upper end of the spiral groove 2a extends vertically upward to the upper end face of the connecting sleeve 2 to form a disassembly groove 2b. The disassembly groove 2b and the limiting protrusion 21 are not on the same diameter line. In this embodiment, the connecting sleeve 2 is designed as a detachable structure, and the suction tube 3 is detachably engaged with the connecting sleeve 2 for easy cleaning. When disassembling the connecting sleeve 2, rotate the switching component 5 to rotate the driving protrusion 5a to the position of the disassembly groove 2b, and the connecting sleeve 2 can be removed (the driving protrusion 5a is separated from the spiral groove 2a through the disassembly groove 2b).

[0026] The cup lid body 1 includes an inner lid 11 and an outer lid 12 fixed together. A flip cover 13 is hinged to the outer lid 12. A locking assembly is provided between the outer lid 12 and the flip cover 13. The locking assembly includes an unlocking element 71 that elastically engages with the outer lid 12. The unlocking element 71 is provided with a locking hook 71a. The flip cover 13 is provided with a locking groove 13a that matches the locking hook 71a. The inner lid 11 has connecting threads that match the cup body. A torsion spring is provided at the hinge of the flip cover 13.

[0027] The unlocking component 71 is provided with a limiting hook 71b for preventing blowout and relieving pressure.

[0028] A vent 11b is provided to ensure pressure balance inside and outside the cup, guaranteeing proper drinking. When the cup is filled with hot water, the internal pressure is high. If the flip cover 13 opens suddenly during unlocking, the hot water may spray out from the vent 11b under the pressure, causing burns and posing a safety hazard. Therefore, this cup lid is equipped with an anti-spray pressure relief structure. Specifically, when unlocking the flip cover 13, the user presses the unlocking component 71 inward, causing the locking hook 71a on the unlocking component 71 to disengage from the locking groove 13a on the flip cover 13, thus opening the flip cover 13. The flip cover 13 will spring open under the action of a torsion spring. During this unlocking process, as the unlocking component 71 is pressed inward, the locking hook 71a disengages from the locking groove 13a, and the limiting hook 71b of the unlocking component 71 enters the locking groove 13a on the flip cover 13, limiting the flip cover 13 and preventing it from opening. The flip cover 13 can only be opened a short distance. As the flip cover 13 is opened, the plug 13c moves away from the vent 11b, and the space inside the cup is connected to the outside space to complete the pressure relief (at this time, the flip cover 13 still covers the surface of the cup lid body 1, so even if a small amount of hot water is sprayed out, it will not cause danger). Then, as the unlocking part 71 moves outward under the elastic force of the return spring 72, the limit hook 71b moves away from the locking groove 13a to release the limit, and the flip cover 13 can be opened, thereby realizing the anti-spray pressure relief function.

[0029] The connecting sleeve 2 has symmetrical limit protrusions 21 on both sides of its outer wall. Correspondingly, there are two lifting grooves 1b. The inner cover 11 has a partition 14 with a notch 14a in the middle. One lifting groove 1b is located on the partition 14, and the other lifting groove 1b is located on the inner wall of the inner cover 11.

[0030] Both ends of the partition 14 are connected to the inner wall of the inner cover 11. This arrangement not only provides a location for one of the lifting slots 1b but also ensures its strength. In direct drinking mode, water flows into the spout 4 from the notch 14a.

[0031] The inner cover 11 is provided with a boss 11a, and the boss 11a is provided with a vent 11b. The outer cover 12 is provided with an assembly hole 12a that matches the boss 11a. The flip cover 13 is provided with a push rod 13b that matches the vent 11b. The lower end of the push rod 13b is provided with a plug 13c.

[0032] The upper end of the switching component 5 is provided with a turntable 51, the turntable 51 is provided with a protrusion 51a, the lower surface of the turntable 51 is provided with a positioning groove 51b, and the inner cover 11 is provided with positioning protrusions 11c that are adapted to the positioning groove 51b and correspond to each state.

[0033] The turntable 51 is exposed on the upper surface of the outer cover 12 or protrudes from the upper surface of the outer cover 12. The rotation of the turntable 51 drives the rotation of the switching component 5. The protrusion 51a facilitates the application of force when the turntable 51 rotates, making state switching more effortless. In addition, the cooperation between the positioning groove 51b and the positioning protrusion 11c indicates that the rotation is in place when switching states. The two sides of the positioning groove 51b are inclined, and correspondingly, the two sides of the positioning protrusion 11c are also inclined. The guiding effect of the inclined surfaces allows the positioning protrusion 11c to accurately enter the positioning groove 51b. In this embodiment, the inner cover 11 is provided with three positioning protrusions 11c, corresponding to the direct drinking state, the sipping state, and the cleaning state, respectively. The upper surface of the outer cover 12 is provided with markings corresponding to each state.

[0034] A return spring 72 is provided between the unlocking component 71 and the outer cover 12, and limit buckles 71c are respectively provided on both sides of the unlocking component 71. The return spring 72 provides the reset force after the unlocking component 71 is pressed to unlock, while the limit buckles 71c prevent the unlocking component 71 from disengaging from the assembly position.

[0035] The flip cover 13 is fixed with a sealing gasket 13d that is adapted to the drinking opening 4a. When the flip cover 13 is closed, the sealing gasket 13d blocks the drinking opening 4a to ensure the sealing of the drinking opening 4a.

[0036] Working principle: The dual-drinking cup lid structure of the present invention shares a single drinking opening 4a for both sipping and direct drinking modes. The structure is compact. In use, the connecting sleeve 2 is raised or lowered by rotating the switching component 5, thereby allowing the upper end of the connecting sleeve 2 to either seal or separate from the cup lid body 1, forming a gap 1a. The design is ingenious and the mode switching is convenient. The limiting protrusion 21 on the outer wall of the connecting sleeve 2 is located in the vertical lifting groove 1b on the cup lid body 1. That is to say, the connecting sleeve 2 can only move up and down along the lifting groove 1b and will not rotate. When the switching component 5 rotates, the driving protrusion 5a of the switching component 5 rotates accordingly. Since the driving protrusion 5a is located in the spiral groove 2a of the connecting sleeve 2, and the driving protrusion 5a acts on the inner wall of the spiral groove 2a, it drives the connecting sleeve 2 to rise or fall.

[0037] In the drinking state, rotating the switching component 5 causes the connecting sleeve 2 to rise until the upper end of the connecting sleeve 2 is sealed with the cup lid body 1. In this way, the inner cavity of the cup forms a drinking channel through the straw 3 and the mouthpiece 4.

[0038] In the direct drinking state, rotating the switching component 5 causes the connecting sleeve 2 to descend, and the upper end of the connecting sleeve 2 separates from the cup lid body 1 to form a gap 1a. In this way, the inner cavity of the cup forms a direct drinking channel through the gap 1a and the spout component 4.

[0039] In the cleaning state, continue to rotate the switching part 5 so that the drive protrusion 5a rotates to the disassembly groove 2b position, and the connecting sleeve 2 can be removed for easy cleaning.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
