Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, to cups, and more particularly to a double-detachable cup lid. Background Technology

[0002] A cup is a common container for holding liquids. Some cups come with lids for easy carrying and to prevent leakage. The lid effectively protects the liquid in the cup, preventing dust, debris, insects, and other external contaminants from entering and ensuring the hygiene and safety of the liquid. The lid is especially important when used outdoors or in open environments.

[0003] Some patents, such as the one with authorization announcement number CN221865384U, provide a threadless water cup, including a cup body, a cup lid detachably mounted on the cup body, the cup lid including an upper shell and a mounting base, a snap-fit ​​component and a first elastic element for driving the snap-fit ​​component to reset are movably mounted on the mounting base, a slot adapted to the snap-fit ​​component is provided on the inner side of the cup body opening, and a drive rod for controlling the movement of the snap-fit ​​component is movably mounted on the upper shell.

[0004] The lid and body can be disassembled by pressing the drive rod. There is no threaded connection between the lid and the body; they are only engaged by a snap-fit ​​mechanism that engages with a slot inside the body of the cup, allowing for flexible assembly and disassembly.

[0005] However, the design of the slot structure in the cup not only increases the difficulty of producing the cup, but also the small distance between the upper end of the sealing bevel that fits with the sealing ring and the upper end of the slot makes it impossible to observe the slot wall or corners, and it is not easy to clean, which can easily lead to bacterial growth and affect drinking safety.

[0006] Furthermore, because the lid lacks a threaded design, it cannot be used with common threaded cups, thus reducing its applicability. Utility Model Content

[0007] This utility model addresses the problems of difficult production, inconvenient cleaning, and low applicability of cups with a snap-fit ​​lid. The technical problem to be solved by this utility model is to provide a double-detachable lid that can reduce the difficulty of cup body production, facilitate cleaning, and has high applicability.

[0012] When the upper cover is connected to the lower cover, the sliding fastener has a limiting part that exposes the main body and is located below the inner edge, and the main body has an outer edge that supports the lower cover. The limiting part and the outer edge can restrict the separation of the upper cover and the lower cover.

[0013] Furthermore, when the pressure-bearing component is subjected to external force, the pressure-bearing component drives the sliding fastener to slide through the inclined surface, and the limiting part on the sliding fastener can disengage from the inner edge, thus separating the upper cover from the lower cover.

[0014] A further preferred embodiment of this utility model is: the number of sliding fasteners is at least two, the sliding fasteners are provided with multiple working cavities, and the pressure-bearing member is provided with a pair of guide blocks that can be inserted into the working cavities.

[0019] A further preferred embodiment of this utility model is: the lower cover is provided with an annular groove, and a pressure sealing ring is installed in the annular groove, so that the cup mouth of the cup body can press against the pressure sealing ring.

[0020] A further preferred embodiment of this utility model is: the lower cover is provided with a stepped surface, the main body is connected to the outer shell, and an insertion cavity is formed between the outer shell and the main body.

[0021] A further preferred embodiment of this utility model is: an annular upper edge protrudes from the stepped surface, the upper edge can be inserted into the insertion cavity, and the lower end of the outer shell can abut against the upper limit of the stepped surface.

[0022] A further preferred embodiment of this utility model is: the cup body is provided with a sealing slope, the main body is fitted with a deformation sealing ring, the deformation sealing ring is provided with a deformation part, and the deformation part can fit into the sealing slope to perform deformation sealing.

[0023] Compared with the prior art, the advantages of this utility model are:

Detailed Implementation

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0037] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0038] This embodiment mainly describes a double-detachable cup lid that reduces the difficulty of cup body production, is easy to clean, and has high applicability, as detailed below:

[0039] like Figure 1-7 As shown, the cup has a double-detachable lid, which includes a detachable cup body 001 and a lid body 002. The lid body 002 includes an upper lid 01 and a lower lid 02. The lower lid 02 is threadedly connected to the cup body 001, allowing the lid body 002 to be detached from the cup body 001 for drinking. The lower lid 02 is also detachably snapped onto the upper lid 01. The lower lid 02 has a through hole 02a that connects to the interior of the cup body 001, so that even when the upper lid 01 is removed, the liquid in the cup body 001 can still be drunk even when the lower lid 02 is installed. This effectively improves the adaptability of the lid body 002. Preferably, the lower lid 02 can also be detachably connected to the cup body 001 by means of external fastening or other methods.

[0040] In this embodiment, the upper cover 01 includes a main component 1 that can be inserted into the through hole 02a of the lower cover 02 and has a mounting cavity 1a, a pressure-receiving component 2 that is slidably disposed in the mounting cavity 1a, a sliding fastener 3 that is slidably disposed in the mounting cavity 1a and is in contact with the inclined surface of the pressure-receiving component 2, and an elastic element 4 that elastically acts on the sliding fastener 3. Two sliding fasteners 3 are used. The elastic action of the elastic element 4 on the sliding fastener 3 can ensure that the pressure-receiving component 2 is in contact with the inclined surface of the sliding fastener 3. Preferably, the sliding direction of the pressure-receiving component 2 is variable.

[0041] The mounting cavity 1a on the main component 1 is open, and the side wall of the mounting cavity 1a is provided with a through-hole 1b. The sliding fastener 3 is provided with a limiting part 3a. Under the elastic action of the elastic member 4, the limiting part 3a on the sliding fastener 3 protrudes out of the through-hole 1b, that is, it is exposed on the outer wall of the main component 1. An inner edge 02b is provided protruding on the hole wall of the through hole 02a of the lower cover 02. When the upper cover 01 and the lower cover 02 are engaged, the limiting part 3a on the sliding fastener 3 is located below the inner edge 02b.

[0042] To ensure the stability of the pressure-bearing component 2 when it is subjected to external force and drives the sliding fastener 3 to slide, the sliding fastener 3 is provided with two working cavities 3b, and the pressure-bearing component 2 is provided with four guide blocks 2a. Two guide blocks 2a form a group, and the two guide blocks 2a in a group are inserted one-to-one into the working cavity 3b of the sliding fastener 3. The guide block 2a is provided with a first inclined surface 2b, and the working cavity 3b is provided with a second inclined surface 3c. The elastic component 4 elastically supports the first inclined surface 2b and the second inclined surface 3c to fit together.

[0043] The downward pressure is applied to the pressure-bearing component 2, which is attached to the inclined surface 3c of the sliding fastener 3 via the inclined surface 2b. This causes the two sliding fasteners 3 to close and interact, so that the limiting part on the sliding fastener 3 slides away from the inner edge 02b. That is, the maximum size of the limiting part 3a on the two sliding fasteners 3 is smaller than the inner size of the inner edge 02b, thus enabling the separation between the upper cover 01 and the lower cover 02.

[0044] Preferably, the distance between the two inclined surfaces 2b on the pressure member 2 is smaller at the top and larger at the bottom, and the distance between the two opposite inclined surfaces 3c on the two sliding fasteners 3 is smaller at the top and larger at the bottom.

[0045] In this application, by splitting the lid 002 into a lower lid 02 connected to the cup body 001 and an upper lid 01 that is not threadedly engaged with the lower lid 02, the inner edge 02b of the sliding fastener 3 that engages with the upper lid 01 is set on the lower lid 02. This simplifies the internal structure of the cup body 001 and effectively reduces the production difficulty of the cup body 001. At the same time, the detachable design of the cup body 001, the lower lid 02 and the upper lid 01 also facilitates the separate cleaning of the cup body 001, the lower lid 02 and the upper lid 01, ensuring hygiene and safety.

[0046] like Figure 2-7As shown, the lower cover 02 is provided with an internal thread section 02c, and the cup body 001 is provided with an external thread section 001a. An annular groove 02d is provided at the upper end of the internal thread section 02c. A pressure sealing ring 10 is installed in the annular groove 02d. When the lower cover 02 and the cup body 001 are threadedly connected through the internal thread section 02c and the external thread section 001a, the upper end of the external thread section 001a, i.e. the cup mouth of the cup body 001, presses against the pressure sealing ring 10, which can effectively prevent water leakage between the upper cover 01 and the cup body 001.

[0047] Furthermore, the main component 1 is provided with a connecting section 1c, and a deformation sealing ring 6 is snapped onto the connecting section 1c. The deformation sealing ring 6 is provided with a snap-fit ​​part 6a that snaps into the connecting section 1c, and a deformable part 6b. In this embodiment, one end of the deformable part 6b is connected to the snap-fit ​​part 6a, and the other end is movably disposed. A deformation cavity 6c is formed between the deformable part 6b and the snap-fit ​​part 6a, and a sealing inclined surface 001b is provided in the cup body 001.

[0048] When the upper cover 01 and the lower cover 02 are snapped together, the deformable part 6b of the deformation sealing ring 6 bends and deforms into the deformation cavity 6c and fits against the sealing inclined surface 001b, thereby achieving a seal between the upper cover 01 and the lower cover 02 and preventing water leakage between the upper cover 01 and the cup body 001. Furthermore, the deformation of the deformable part 6b of the deformation sealing ring 6 exerts an upward force on the upper cover 01, causing the upper end face of the limiting part 3a to fit against the lower end face of the inner edge 02b.

[0049] To facilitate the fastening of the upper cover 01 and lower cover 02, the lower outer corner of the limiting part 3a and the upper inner corner of the upper edge are beveled or chamfered.

[0050] like Figure 2-7 As shown, the lower cover 02 has a stepped surface 02e located above the annular groove 02d. An annular upper edge segment 02f protrudes from the stepped surface 02e. The main component 1 is connected to a shell 5, which covers a portion of the main component 1. The main component 1 has an outer edge 1d, which forms a cavity 01a between the main component 1 and the shell 5. When the upper cover 01 and the lower cover 02 are engaged, the upper edge segment 02f on the lower cover 02 is inserted into the cavity 01a, and the lower end of the shell 5 can abut against the upper limit of the stepped surface 02e.

[0051] The outer shell 5 has an opening 5a that connects to the mounting cavity 1a. The pressure-bearing member 2 has a stop surface 2c. The outer dimension of the stop surface 2c is larger than the inner dimension of the opening 5a, so that the pressure-bearing member 2 will not detach from the upper cover 01 under the action of the inclined surfaces of the two sliding fasteners 3. The stop surface 2c of the pressure-bearing member 2 has a protruding pressure-bearing part 2d, which is located in the opening 5a. Preferably, when there is no external force acting on the pressure-bearing member 2, the upper end surface of the pressure-bearing part 2d can be flush with the upper end surface of the outer shell 5.

[0052] like Figure 3-7As shown, the mounting cavity 1a of the main component 1 is provided with an action post 1e. The elastic element 4 of the elastic sliding fastener 3 can be provided between the sliding fastener 3 and the action post 1e. The action post 1e is provided with a through hole 1f and a limiting hole 1g. The through hole 1f is provided through the entire part, and the inner diameter of the limiting hole 1g is larger than the inner diameter of the through hole 1f. The limiting hole 1g is connected to the upper end face of the action post 1e.

[0053] An elastic support 7 is installed in the limiting hole 1g, and a guide rod 8 is inserted into the through hole 1f. A sealing gasket 9 is snapped and fixed near the lower end of the guide rod 8. The sealing gasket 9 is located below the main body. The pressure-bearing component 2 has a slot 2e with a lower opening. The elastic support 7 elastically acts on the guide rod 8, so that the sealing gasket 9 seals the lower end of the through hole 1f, and the upper end of the guide rod 8 is inserted into the slot 2e.

[0054] To ensure the stability of the pressure-bearing component 2 and the guide rod 8 when the pressure-bearing component 2 is pressed down, a rib 8a is provided on the side wall of the guide rod 8, and a groove 1h is provided on the action column 1e, and a groove 2f is provided on the side wall of the slot 2e. The rib 8a is located in the groove 1h and the groove 2f. Preferably, the maximum height dimension between the groove 1h and the groove 2f is greater than the height dimension of the rib 8a.

[0055] When the pressure-bearing component 2 is subjected to downward pressure, it will not only cause the two sliding fasteners 3 to close, thus separating the upper cover 01 from the lower cover 02, but also cause the guide rod 8 to press down, making the sealing gasket 9 away from the lower end face of the main body, so as to realize the air venting and pressure release of the through hole 02a, making it easier for the upper cover 01 to separate from the lower cover 02.
