HANDY CUP LID

Description

TECHNICAL FIELD

The present disclosure relates to the technical field of a water cup, and more specifically, to a handy cup lid.

BACKGROUND

The common cup with lid on the market is dominated by the spiral connection structure. Definitely, matching threads are set on the lid body and the cup body, allowing the lid body to be connected with the cup body after the rotation. This requires the operation by both hands, and fails to meet the demand of opening the lid with single hand.

With the development of technology, there is a non-threaded cup lid, such as the non-threaded insulation cup disclosed by CN116115053A, in which the cup is sealed or unsealed by the silicone gasket at the bottom. During the sealing, the lid needs to be pressed, and the connection attachment needs to be pushed by force during the unsealing, which is still inconvenient for one-handed operation. In addition, the internal structure of the lid is complex, and an integrated structure is adopted, as a result, the internal parts of the lid cannot be replaced or repaired.

CONCRETE EMBODIMENTS

The technical plan of the present disclosure is further explained by examples and drawings.

Example 1

FIG. 1 and FIG. 2 show the structural diagrams of Example 1 of the lid in the present disclosure; The handy cup lid in Example 1 comprises three parts: Lid body 1, Cover 2 and Lock ring 3.

As shown in FIG. 3 and FIG. 4, the Lid body 1 consists of Bottom plate 11 and Ring wall 12 extending upward along Bottom plate 11. An accommodating space of the upper opening is formed between Ring wall 12 and Bottom plate 11. Two symmetrical card slot holes 121 are provided at the lower ends of Ring wall 12. Pressure relief hole is provided on Bottom plate 11.

Two sets of positioning frames 41 are provided in the accommodating space. Positioning frame 41 is provided with a card slot with openings. The two sets of positioning frames 41 are in the same line and correspond to the two card slot holes 121. Gear 42 is clamped on each set of Positioning frames 41. The two ends of Gear 42 are provided with rotating shafts, which are clamped in the card slots of Positioning frame 41, so that it is easy to disassemble and separate the gear and positioning frame during the barrier-free rotation. Spring bolt 43 is arranged respectively under Gear 42. As shown in FIG. 4, the upper surface of Spring bolt 43 is provided with a Second tooth 431, and the second tooth 431 is engaged with the gear tooth of the Gear 42. The rotating of Gear 42 drives Spring bolt 43 to move forward or backward. The lower surface of Spring bolt 43 on the front end is provided with Push plate 432. A positioning plate 44 is provided under each Spring bolt 43. A First return spring 45 is arranged between Positioning plate 44 and Push plate 432 of the Spring bolt 43. Under normal conditions, the First return spring 45 is released, pushing the Push plate 432, so that Spring bolt 43 stretches out from Card slot hole 121; The First return spring 45 contracts under the drive of Gear 42, and Spring bolt 43 returns to the accommodating space. The end of Spring bolt 43 is provided with Limit device 433, projecting outwards to push against Positioning frame 41.

As shown in FIG. 3 and FIG. 4, two sets of vertical Racks 21 are arranged on the lower surface of Cover 2, and two first teeth 211 are respectively arranged on Rack 21. When Cover 2 is fixed on Lid body 1, the two sets of Racks 21 are respectively located between Gear 42 and Ring wall 12. When the Cover 2 is pressed, the First tooth 211 is engaged with Gear 42, pressing Gear 42 down, and Gear 42 rotates to drive Spring bolt 43 to move inward and return to the accommodating space. The stretching and retraction of Spring bolt 43 can be controlled through the coordination of the rack in Cover 2 with the gear in Lid body 1 and the First return spring 45.

Preferably, Linear sliding rail 46 is arranged along two Positioning frames 41. The bottom of Spring bolt 43 is connected with the linear slide rail or matched with each other. Linear slide rail 46 acts as the bottom support for Positioning frame 41 while serving as a limit for Spring bolt 43, to support the spring bolt extended straightly and keep Spring bolt 43 stable and steady. In addition, two Limit baffles 47 are arranged in the accommodating space, clamping Spring bolt 43, so as to further ensure that Spring bolt 43 moves in the straight direction without interfering with its movement.

Lock ring 3 connects Cover 2 and Lid body 1 as one. In this example, as shown in FIG. 4, Locking edge 22 stretches out from the side wall of Cover 2. The outer side of Ring wall 12 is provided with several L-shaped slots 122, and a raised Strip 123 is provided in the L-shaped slot 122. Locking ring 3 comprises Locking ring wall 31 and Seal 32 perforated in the middle of the upper surface of Locking ring wall 31, the bottom of Locking ring wall 31 is provided with Convex block 33 matching the L-shaped slot 122, and Convex block 33 is provided with Slot 331 in the middle. When Locking ring wall 31 is inserted into the L-shaped slot 122 on the outside of Ring wall 12 and rotated, the strip can be pushed with a little force, so that Strip 123 is embedded in Slot 331 and the connection stability is increased. Seal 32 of Locking ring 3 restricts Locking edge 22 other than the up and down movement of Cover 2.

As shown in FIGS. 1 and 3, Pressure relief push rod 5 is provided in Pressure relief hole 111 of Bottom plate 11. The bottom of Pressure relief push rod 5 is provided with Sealing plug 51 blocking Pressure relief hole 111, and is equipped with a Second return spring 52. The lower part of Cover 2 is provided with Locating groove 23 (open side down), to match the top part of the pressure relief push rod. When Cover 2 is pressed down, the Second return spring 52 contracts, Sealing plug 51 moves down with Pressure relief push rod 5, to open Pressure relief hole 111, so that the gas enters the accommodating space between Lid body 1 and Cover 2 through Pressure relief hole 111. The pressure relief structure in this example is also removable. Pressure relief push rod 5 comprises a Top raised limit 53 and a Ring limit 54 with an opening, and the ring limit is stuck below the raised limit, to restrict the movement of the second return spring; Sealing plug 51 is connected with the bottom of Pressure relief push rod 5 in a Detachable manner. After long-term use, the structure can be disassembled easily without causing mildew and other phenomena due to the entry of pressure relief gas. Meanwhile, the part damaged, if any, can be removed and replaced directly.

As shown in FIG. 4, the inner wall of Ring wall 12 is provided with Positioning convex bar 124 and the side wall of Locking edge 22 of Cover 2 is provided with Positioning slot 221. During the assembly, Positioning slot 221 and Positioning convex bar 124 can be easily mated for fast connection.

A sealing strip slot 13 is set under Card slot hole 121 of Ring wall 1, and is equipped with a sealing strip, to increase the water tightness of the lid.

As shown in FIG. 5 and FIG. 6, the handy cup lid of the present disclosure is locked by controlling the expansion and contraction of the spring bolt and Lock groove 61 of Cup body 6. Relying on the original structure of this application, the one-hand operation can be achieved by the user with less strength. In addition, the components in this example, such as the gear, each return spring, and pressure relief push rod, can be disassembled to facilitate the cleaning after long-term use or replacement after component damage.

Example 2

As shown in FIGS. 7-12, Example 2 differs from Example 1 in that Straw port 14 is provided on Bottom plate 11 of Lid body 1. Butt tube 141 protruding from the accommodating space is provided at Straw port 14. Cover 2 is provided with Hole 24 and Diversion tube 25 is extended under the hole. Diversion tube 25 is inserted into Butt tube 141 and Sealing ring 251 is arranged between Diversion tube 25 and Turning straw 26. When the cover is pressed down, Diversion tube 25 moves downward with Cover 2 and passes through Diversion tube 25.

As shown in FIGS. 10 and 11, Turning straw 26 is provided in Hole 24. Turning straw 26 is connected with Diversion tube 25 after release, and the passage between Turning straw 26 and Diversion tube 25 is closed after contraction. As shown in FIG. 7 and FIG. 8, the upper surface of Cover 2 is formed into an Inward storage groove 27, to accommodate the turning straw contracted.

Example 3

This example differs from other examples in that the gear tooth contacting the second tooth of the spring bolt is provided with a resistance bar. If the cover is pressed, the resistance bar will push against the second tooth downward when being in contact with the second tooth, and then drive the spring bolt as a whole to move downwards. The upper surface of the part of the spring bolt stretching out from Card slot hole 121 is provided with several engaging strips, and the upper surface of the lock groove of the cup body is also provided with an engaging groove for response.

In the locking state, with the engaging strip and the engaging groove, the connection tightness between the lid and the cup body can be increased; When the cover is pressed, the engaging strip is separated from the engaging groove, allowing the spring bolt to exit from the lock groove of the cup body smoothly.

Example 4

As shown in FIGS. 13-16, unlike the above examples, Cover 2 is provided with Direct drinking spout 28 and Turning straw 26. Water outlet 112 corresponding to the Direct drinking spout 28 is provided on the bottom plate of the lid body, and Connecting tube 7 is provided between Water outlet 112 and Direct drinking spout 28. Direct drinking cover 29 is provided on Cover 2. The two legs of Direct drinking cover 29 are connected to the upper surface of Cover 2 through a hinge, allowing it to rotate.

As shown in FIG. 15, Drinking gasket 281 is connected at Direct drinking spout 28 for easy removal, cleaning or replacement.
