[0037] The following further elaborates on the detailed implementation manners of the present utility model with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for the purpose of illustration and explanation of the present utility model, and are not intended to limit the present utility model.
[0038] In the present utility model, unless otherwise stated, the directional terms such as "up, down, inside, outside" included in the terms only represent the directions of the terms in the normal use state, or are the common names understood by those skilled in the art, and should not be regarded as a limitation of the terms.
[0039] As Figure 1-7 shown, the present utility model provides a quick-twist cap device with a handle. The device includes: a locking ring 4 arranged at the open end of a container, a lid body 1, and a sealing ring 3 locked on the lid body 1. Along the circumferential direction of the locking ring 4, a plurality of locking protrusions 401 are arranged at intervals. On the inner side wall of the lid body 1, locking slots 107 corresponding to the plurality of locking protrusions 401 one by one are provided. By rotating the lid body 1, each locking protrusion 401 can be snapped into the corresponding locking slot 107, and the open end of the container abuts against the sealing ring 3.
[0040] In the above solution, when the device is in use, the locking ring 4 is fixed at the open end of the container, the lid body 1 is covered on the open end of the container, and the lid body 1 is rotated so that each locking protrusion 401 is snapped into the corresponding locking slot 107. The inner sealing ring 3 abuts against the open end of the container. This structure not only facilitates quick disassembly operation for users, but also ensures the stability and sealing performance after assembly.
[0041] In a preferred embodiment of the present utility model, a handle 101 is arranged on the upper surface of the lid body 1.
[0042] In the above solution, the arrangement of the handle 101 can make it more convenient for users to operate the quick-twist cap and is more conducive to applying force. As Figure 1 shown, the shape of the handle 101 is "C"-shaped, and its two ends are respectively fixed on the opposite side edges of the upper surface of the lid body 1. A plurality of depressions are arranged on the side surface of the handle 101, which can further increase the friction force and play an anti-slip role. The corners are also processed with arcs to ensure the holding feel.
[0043] In a preferred embodiment of the present utility model, a plurality of ventilation holes 102 are arranged through the middle of the lid body 1, and a sealing groove 105 is arranged at the inner top end thereof. A sealing gasket 2 capable of covering all the ventilation holes 102 is arranged in the sealing groove 105, and a top part of the sealing gasket 2 penetrates through the lid body 1 to form a limiting protrusion 201.
[0044] In the above solution, external air can enter through the ventilation holes 102 and then enter the interior of the container through the gap between the sealing gasket 2 and the sealing groove 105. In this way, during the process of pumping the liquid inside by a pump body, the pressure inside the container can be maintained relatively constant to ensure normal pumping operation of the liquid.
[0045] However, the gas and liquid inside the container cannot overflow because after gas is generated inside, the internal pressure increases, or the liquid sloshing will impact the sealing gasket 2, causing it to closely adhere to the sealing groove 105, thereby covering all the ventilation holes 102, so that the gas and liquid inside cannot overflow from the ventilation holes 102, achieving the function of preventing liquid leakage. This structure can be simply understood as similar to the function of lifting a one-way valve.
[0046] In a preferred embodiment of the present utility model, a plurality of limiting posts 106 are provided at the inner bottom end of the lid body 1, and limiting locking rings 301 corresponding to the plurality of limiting posts 106 are formed on the sealing ring 3.
[0047] In the above solution, the sealing ring 3 is sleeved on the limiting posts 106 through a plurality of limiting locking rings 301 at the edge to achieve the locking effect on the sealing ring 3, which can prevent the sealing ring 3 from falling off the lid body 1, ensuring the sealing performance of the lid body. In the prior art, the sealing ring 3 does not have a locking structure, and when opening and closing the lid body, the sealing ring 3 above is prone to falling off, which will not only contaminate the sealing ring, but also, if not noticed, the sealing performance cannot be guaranteed without the function of the sealing ring 3.
[0048] In a preferred embodiment of the present utility model, a notch 402 is provided on the locking ring 4, and adjusting blocks 403 are respectively provided at both ends of the notch 402, and an adjusting bolt 404 is threadedly penetrated between the two adjusting blocks 403.
[0049] In the above solution, the structure of the locking ring 4 can improve its scope of application. Users can rotate the adjusting bolt 404 according to the diameter of the open end of the container 5, so that the locking ring 4 can be stably fixed at the open end of the container 5. In this way, when cooperating with the lid body 1 later, the tightness and stability of the closing can be ensured, and the structure of the notch can make the locking ring 4 applicable to containers 5 with different calibers within a certain range.
[0050] As Figure 6 shown, in a preferred embodiment of the present utility model, the width of the locking protrusion 401 gradually increases from one end to the other along its length direction, and the internal width of the locking groove 107 gradually decreases from the opening to the inside.
[0051] In the above solution, the locking ring 4 is locked at the open end of the container. When closing the lid body 1, each locking protrusion 401 is aligned with the gap between the two locking grooves 107, and then the lid body 1 is rotated. In this way, the smaller end of the locking protrusion 401 enters from the larger end of the locking groove 107 and gradually moves towards the smaller end of the locking groove 107, achieving the effect of being tightened more and more as it rotates.
[0052] In a preferred embodiment of the present utility model, the end portions of the side plates 108 of each locking card slot 107 located at the open ends are respectively arc-shaped, and a strip-shaped slot 109 is also provided at this end portion.
[0053] In the above solution, the structure of the side plate 108 cooperates with the structure of the strip-shaped slot 109. First, the portion of the side plate 108 near the open end has elasticity. In this way, after the locking protrusion 401 is inserted into the locking card slot 107, the side plate 108 can undergo elastic deformation to achieve the effect of snap-locking, and it is also convenient for quick disassembly operation in the later stage.
[0054] In a preferred embodiment of the present utility model, a plurality of anti-slip grooves 104 are spacedly arranged on the outer side surface of the lid body 1.
[0055] In the above solution, the anti-slip grooves 104 can facilitate the user to rotate and operate the lid body 1 to achieve the anti-slip effect, and it is also convenient for assembly and quick disassembly operations.
[0056] In a preferred embodiment of the present utility model, a tightness indication mark 103 is also provided on the outer side surface of the lid body 1.
[0057] In the above solution, the tightness indication mark 103 can intuitively remind the user which direction to rotate to achieve the tightening effect and which direction to rotate to open the lid body 1.
[0058] In summary, when the quick-tightening lid device with a handle provided by the present utility model is in use, it overcomes the problem that it is laborious to tighten the bottle cap in the existing lid structure, and when performing the capping operation, if the force is uneven or the thread processing is poor, it may lead to a decrease in the sealing performance, and the thread structure also has higher requirements for the precision of the process during processing.

To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.
[0061] In addition, any combination can be made among various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, and it should equally be regarded as the content disclosed by the present utility model.
