Description

Cup lid structure and container Technical Field

[0001] The present invention relates to the technical field of cup covers, and in particular to a cup cover structure and a container. Background Art

[0002] Most cup lids and cup bodies are split structures, and opening and closing are achieved by tight fit of the sealing ring around the cup lid, threaded connection, etc. These opening and closing methods require the use of two hands to open and close the cup lid, which is especially not suitable for driving, sports and other environments where only one-handed operation is convenient. In addition, the above-mentioned environments are prone to shaking and vibration. At the same time, the cup lid is in a completely open state after opening, and the water in the cup is easy to spill out from the open cup mouth, splashing onto the user and the environment, causing inconvenience.

[0003] Therefore, some manufacturers have designed a button-type lid opening method, that is, by pressing a movable lid pivotally connected to the cup lid to open and close the movable lid, thereby opening a smaller through-hole for drinking water. However, in the process of popping open the movable lid, water in contact with the movable lid is often brought out together, causing splashing, and the lid becomes difficult to open after aging of the spring. At the same time, the aforementioned methods are sealed. When the cup contains hot water and is left for a long time to cool, it will become difficult to open the cup lid due to the air pressure difference, which is especially difficult for people with less strength to open.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to provide a cup cover structure and container to solve the problems existing in the prior art and the inconvenience of operation of the existing cup cover, so that it can be opened quickly and effortlessly with one hand to achieve the purpose of drinking water.

[0013] Preferably, there are two limiting flanges, which are symmetrically arranged on both sides of the boss, and there are two notches in the limiting ring groove.

[0014] Preferably, the side wall of the air guide groove is provided with at least one limiting portion, which protrudes from the side wall of the air guide groove and is used to limit the stroke of the air guide tube to limit the rotation angle of the sub-cover body, thereby preventing the sub-cover body from rotating to the angle corresponding to the relative state of the limiting flange and the notch.

[0015] Preferably, the limiting portion is a spring sheet provided on the side wall of the air guide groove; the limiting portion is provided at relative positions on both side walls of the air guide groove.

[0016] Preferably, the limiting portion is arranged between the two ends of the air guide groove, and the movement of the air guide tube between one end of the air guide groove and the limiting portion corresponds to the rotation of the sub-cover body to open and close the water hole, and when the air guide tube abuts the other end of the air guide groove, the limiting flange is opposite to the notch.

[0017] Preferably, the convex column is made of transparent material.

[0035] DETAILED DESCRIPTION

[0036] 1 to 8 , the present invention discloses a cup cover structure, comprising a main cover body 1 and a secondary cover body 2;

[0037] The main cover 1 is used to movably seal the opening of the cup, and a water hole 11 and an air guide tube 12 are provided on its upper surface;

[0038] The auxiliary cover body 2 can be rotatably engaged with the upper surface of the main cover body 1, and is axially limited with the main cover body 1 to prevent the auxiliary cover body 2 from falling off the main cover body 1; the auxiliary cover body 2 is provided with a water outlet 21 for opening and closing the water hole 11 as the auxiliary cover body 2 rotates, and an air guide groove 22 for the air guide pipe 12 to movably engage, and the air guide groove 22 is connected to the atmosphere.

[0039] The invention also provides a method for opening and closing the water hole 11 by rotating the auxiliary cover 2 relative to the main cover 1. The air guide tube 12 of the main cover 1 is movably matched with the air guide groove 22 of the auxiliary cover 2 and the air guide groove 22 is connected to the atmosphere. The air guide tube 12 is always connected to the atmosphere, and the air pressure inside and outside the cup is kept balanced, making the operation of rotating the auxiliary cover 2 labor-saving and simple, and can be performed with one hand. In addition, the cooperation between the air guide tube 12 and the air guide groove 22 also limits the rotation angle of the auxiliary cover 2. One of the end points is designed to correspond to the angle when the water outlet 21 and the water hole 11 overlap, so that quick opening and closing can be achieved, and the user operation experience is better. The product of the present invention does not need to be completely sealed, but can provide a small-caliber water hole 11 that can be opened and closed quickly and conveniently. It is particularly suitable for application scenarios such as car cups, improving the simplicity of user operation and reducing safety hazards.

[0040] Specific embodiments of the present invention are shown below.

[0041] The air guide groove 22 is provided with a connecting groove 23 that connects to the peripheral surface of the auxiliary cover body 2. The depth of the connecting groove 23 is greater than that of the air guide groove 22, so that a step is formed between the two. When the auxiliary cover body 2 is rotated to the position where the water hole 11 and the water outlet 21 are opposite each other, the air guide tube 12 is located in a position connected to the connecting groove 23. This structure ensures that after the auxiliary cover body 2 is rotated to the position where the water hole 11 and the water outlet 21 are opposite each other, the air guide tube 12 achieves the maximum ventilation flow rate because it is directly opposite the connecting groove 23. It can quickly balance the air pressure difference between the inside and outside of the cup, so that water can flow smoothly out of the water hole 11, avoiding the feeling of discontinuity when pouring water from the smaller water hole 11, and improving the user experience. At the same time, when the water hole 11 is not open, the air guide tube 12 is located within the air guide groove 22 and away from the connecting groove 23. The two sides of the air guide tube 12 are surrounded by the air guide groove 22, and the corresponding water leakage is greatly reduced.

[0042] Furthermore, the above-mentioned water hole 11 and the air duct 12 are located at the two ends of the same diameter of the main cover body 1, and the connecting groove 23 and the water outlet 21 are located at the two ends of the same diameter of the auxiliary cover body 2, which is convenient for product design and more beautiful, and also avoids as much as possible the situation where the water hole 11 is aligned with the water outlet 21 while the air duct 12 is not aligned with the connecting groove 23 due to product tolerance.

[0043] Secondly, because the air duct 12 is always connected to the atmosphere through the air duct groove 22 and the connecting groove 23, when the cup is stored in an environment prone to shaking, such as a car, it is inevitable that a small amount of water will splash out from the end of the air duct 12 and may flow through the connecting groove 23 to the upper surface of the main cover 1. In this case, the upper surface of the main cover 1 is designed as a circular groove 13 structure, the bottom wall of the circular groove 13 is inclined with respect to the axis of the main cover 1, and the water hole 11 is located at the lowest position of the circular groove 13, and the air duct 12 is located at the highest position of the circular groove 13. With this structure, even if a small amount of water splashes / overflows, due to the small amount of water, it is blocked by the side wall of the circular groove 13 and will not splash outside the circumference of the cup. Instead, it will return to the air duct 22 or flow along the inclined bottom wall of the circular groove 13 to the water hole 11.

[0044] Furthermore, a pouring trough 14 is provided on the side wall of the circular groove 13 at the position corresponding to the water hole 11. The side wall of the pouring trough 14 is expanded and inclined outward toward the outer periphery of the main cover body 1, so that water flowing out of the water hole 11 can be collected in the pouring trough 14 and flow out of the main cover body 1, which provides the user with a better drinking experience.

[0045] The upper surface of the above-mentioned main cover body 1 is provided with a boss 15, and the circumferential surface of the boss 15 is provided with at least one circumferential limiting flange 16; the auxiliary cover body 2 is an annular structure and is provided with a through hole 24 sleeved on the boss 15, and the side wall of the through hole 24 is provided with a limiting ring groove 25 for the limiting flange 16 to movably cooperate, and the lower edge of the limiting ring groove 25 is provided with a notch 26 for the limiting flange 16 to enter and exit the limiting ring groove 25; the limiting flange 16 enters the limiting ring groove 25 through the notch 26 and movably cooperates in the limiting ring groove 25 to realize the rotational cooperation of the auxiliary cover body 2 and the main cover body 1, and the rotation of the auxiliary cover body 2 can change the overlapping area of ​​the water outlet 21 and the water hole 11, thereby realizing the opening and closing and flow adjustment of the water hole 11. This structure sets the rotational cooperation structure of the main cover body 1 and the auxiliary cover body 2 between the boss 15 of the main cover body 1 and the through hole 24 of the auxiliary cover body 2. There is no need to open holes other than the water hole 11 and the air guide tube 12 on the main cover body 1, which reduces the risk of water leakage when the product is used; at the same time, the cooperation between the limiting flange 16 and the limiting ring groove 25 can prevent the auxiliary cover body 2 from falling off the main cover body 1. In this embodiment, the above-mentioned boss 15 is set on the axis of the above-mentioned circular groove 13; the number of limiting flanges 16 is set, and they are symmetrically arranged on both sides of the boss 15. Correspondingly, there are also two notches 26 of the limiting ring groove 25. Through the cooperation of the two limiting flanges 16 and the limiting ring groove 25, the force on both sides of the auxiliary cover body 2 is balanced, the structure is more stable, and it is not easy to tilt to one side.

[0046] Furthermore, the sidewall of the air guide groove 22 is provided with at least one limiting portion 27. The limiting portion 27 protrudes from the sidewall of the air guide groove 22 and is used to limit the travel of the air guide tube 12 to limit the rotation angle of the sub-cover body 2, thereby preventing the sub-cover body 2 from rotating to the angle corresponding to the position where the limiting flange 16 is opposite to the notch 26. By providing the limiting portion 27, the user can be prevented from rotating the sub-cover body 2 to the position where the limiting flange 16 is opposite to the notch 24 during normal use. The air guide tube 12 flexibly cooperates between one end of the air guide groove 22 and the limiting portion 27, corresponding to the sub-cover body 2 switching between the fully closed and fully opened states of the water passage hole 11 of the main cover body 1. When the user needs to remove the sub-cover body 2, they only need to use greater force to rotate the sub-cover body 2 and allow the air guide tube 12 to pass over the limiting portion 27. The two limiting portions 27 are arranged on the same side of the connecting groove 23; the limiting portion 27 is arranged between the two ends of the air guide groove 22: when the air guide tube 12 moves between one end of the air guide groove 22 and the limiting portion 27, the sub-cover 2 switches between the open and closed states of the water passage 11; when the air guide tube 12 passes over the limiting portion 27 and moves to the other end of the air guide groove 22, the sub-cover 2 rotates to the angle where the limiting flange 16 and the notch 26 are relative, and the sub-cover 2 can be disassembled. The air guide groove 22 of this section gives way to the movement of the air guide tube 12 during the rotation of the sub-cover 2 and continues to play a guiding role, and at the same time, it can prevent shaking during the disassembly of the sub-cover 2 and the splashing of water.

[0047] At the same time, the air guide groove 22 is an arc-shaped groove coaxially arranged with the protruding column 15 , and the air guide tube 12 moves in the air guide groove 22 as the auxiliary cover body 2 rotates.

[0048] Secondly, the protruding column 15 is made of a transparent material and can be used to observe the situation inside the cup.

[0049] The upper surface of the auxiliary cover 2 is provided with a handle protrusion 28 to facilitate the user to move and rotate the auxiliary cover 2.

[0050] The circumference of the main cover body 1 is provided with a mounting ring groove 17 , and a sealing ring 3 is provided in the mounting ring groove 17 . After the main cover body 1 and the sealing ring 3 are assembled, a movable seal can be achieved with the opening of the cup.

[0051] Furthermore, a handle 18 is provided on the circumference of the main cover 1, which can provide a place for the user to apply force to pry open the main cover 1 to separate the main cover 1 from the cup, thereby quickly opening the main cover 1. In this embodiment, the handle 18 is provided on the opposite side of the water hole 11.

[0052] In addition, an external thread may be provided on the peripheral surface of the main cover body 1 to realize threaded connection with the internal thread of the cup opening to achieve the purpose of movable sealing.

[0053] The side wall of the water outlet 21 is provided with a latching position 29 . The latching position 29 is an inclined surface or a curved surface recessed in the side wall of the water outlet 21 , which facilitates latching of the auxiliary cover 2 .

[0054] A sealing gasket 4 is provided on the lower surface of the auxiliary cover 2 , and the sealing gasket 4 is used to movably seal the water hole 11 of the main cover 1 .

[0055] As shown in FIG. 9 , the cup cover structure described above can be applied to containers 4 including but not limited to stainless steel cups, enamel cups, and glass cups that can be used to hold water.
