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 that require one-handed operation. In addition, the above-mentioned environments are prone to shaking and vibration, and the cup lid is in a completely open state after opening. 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.

[0006] In order to achieve the above object, one of the solutions of the present invention is:

[0007] A cup cover structure comprises a main cover body and a sub-cover body; the main cover body is used to movably seal the opening of the cup, and a water through hole and an air guide tube are provided on its upper surface; the sub-cover body is rotatably engaged with the upper surface of the main cover body and is axially limited with the main cover body; the sub-cover body is provided with a water through port for opening and closing the water through hole as the sub-cover body rotates, and an air guide groove for movably engaging with the air guide tube, and the air guide groove is connected to the atmosphere.

[0008] The air guide groove is provided with a connecting groove connected to the peripheral surface of the auxiliary cover body, the depth of the connecting groove is greater than the depth of the air guide groove, and when the auxiliary cover body is rotated to the state where the water hole is opposite to the water outlet, the air guide pipe is located in a position connected to the connecting groove.

[0009] Preferably, the water hole and the air duct are located at both ends of the same diameter of the main cover body, and the connecting groove and the water outlet are located at both ends of the same diameter of the auxiliary cover body; a circular groove is provided on the upper surface of the main cover body, the bottom wall of the circular groove is inclined to the axis of the main cover body, and the water hole is provided at the lowest position of the circular groove, and the air duct is provided at the highest position of the circular groove.

[0010] Preferably, a convex column is provided at the axis of the circular groove, and the convex column is made of a transparent material; the auxiliary cover body is an annular structure sleeved on the convex column.

[0011] Preferably, the upper end of the annular wall of the auxiliary cover body protrudes radially inwardly along the auxiliary cover body to form a retaining ring; the retaining ring is movably and sealingly fitted on the top surface of the boss, and protrudes toward the top surface of the boss to form a sealing flange.

[0012] Preferably, the upper surface of the auxiliary cover body is provided with a handle convex point; the air guide groove is an arc groove coaxially arranged with the convex column, and the air guide tube moves between the two ends of the air guide groove as the auxiliary cover body rotates.

[0013] The side wall of the water outlet is provided with a hand-holding position.

[0014] The lower surface of the auxiliary cover body is provided with at least one buckle, and the upper surface of the main cover body is provided with an arc-shaped buckle groove for the buckle to hook and flexibly engage.

[0015] Alternatively, the cup lid structure further includes a first magnet and a second magnet; the main lid and the auxiliary lid are respectively provided with a first mounting groove and a second mounting groove on opposing surfaces thereof; the first magnet and the second magnet are respectively secured within the first mounting groove and the second mounting groove by a sealing compound; and two first magnets are provided corresponding to the second magnet, with the positions of the two first magnets corresponding to the open and closed states of the auxiliary lid relative to the main lid.

[0016] The second solution of the present invention is:

[0017] A container comprises the cup cover structure.

[0018] After adopting the above technical solution, the present invention has the following technical effects:

[0019] ① The overlapping area of ​​the water outlet and the water hole is changed by rotating the sub-cover relative to the main cover, thereby realizing the movable opening and closing of the water hole. Since the air guide tube of the main cover and the air guide groove of the sub-cover are movably coordinated and the air guide groove is connected to the atmosphere, the air guide tube is always connected to the atmosphere, maintaining the air pressure balance inside and outside the cup, making the operation of rotating the sub-cover labor-saving and simple, and can be performed with one hand. In addition, the coordination between the air guide tube and the air guide groove also serves as a limit for the rotation angle of the sub-cover. By designing one of the end points to correspond to the angle when the water outlet and the water hole overlap, the sub-cover can be quickly opened and closed, and the user operation experience is better.

[0020] ② The product of the present invention does not need to be completely sealed, but can provide a small-diameter water hole that can be opened and closed conveniently and quickly. It is particularly suitable for application scenarios such as car cups, improving the user's ease of operation and reducing safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] DETAILED DESCRIPTION

[0044] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0045] 1 to 13 , the present invention discloses a cup cover structure, comprising a main cover body 1 and a secondary cover body 2;

[0046] 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;

[0047] 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.

[0048] In some embodiments of the present invention, 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 a 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 allows the air guide tube 12 to achieve maximum ventilation flow due to being directly opposite the connecting groove 23 after the auxiliary cover body 2 is rotated to a position where the water hole 11 and the water outlet 21 are opposite each other. This can quickly balance the pressure difference between the inside and outside of the cup, allowing water to 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.

[0049] 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.

[0050] 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.

[0051] Furthermore, a boss 14 is provided at the axis of the above-mentioned circular groove 13, and the sub-cover body 2 is an annular structure sleeved on the boss 14, and the boss 14 plays a positioning role for the installation and rotation of the sub-cover body 2; the upper surface of the sub-cover body 2 is provided with a dial convex point 24, which is convenient for the user to dial and rotate the sub-cover body 2; the air guide groove 22 is an arc groove coaxially arranged with the boss 14, and the air guide tube 12 moves between the two ends of the air guide groove 22 as the sub-cover body 2 rotates, which can play a role in limiting the rotation angle of the sub-cover body 2. In the first and second embodiments described below, the boss 14 is made of a transparent material and can be used to observe the situation inside the cup; in the second embodiment described below, the upper end of the annular wall of the above-mentioned auxiliary cover body 2 protrudes inward along the radial direction of the auxiliary cover body 2 to form a circle of retaining rings 25, and the retaining rings 25 are movably fitted on the top surface of the boss 14, and protrude facing the top surface of the boss 14 to form a circle of sealing flanges 251, which play a sealing role and prevent water from leaking from between the annular wall of the auxiliary cover body 2 and the boss 14.

[0052] Finally, a pouring trough 15 is provided on the side wall of the circular groove 13 at the position corresponding to the water hole 11. The pouring trough 15 has an inclined surface that expands 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 15 and flow out of the main cover body 1, providing users with a better drinking experience.

[0053] In some embodiments of the present invention, the circumferential surface of the main cover body 1 is provided with an installation ring groove 16 for installing a sealing ring, which can achieve a movable seal with the opening of the cup after being assembled with the sealing ring.

[0054] Furthermore, the main cover 1 is provided with a handle 17 on its circumference, 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 addition, the main cover 1 can also be provided with an external thread on its circumference to be threadedly connected to the internal thread of the cup opening to achieve the purpose of movable sealing.

[0055] In some embodiments of the present invention, a handle position 26 is provided on the side wall of the water outlet 21 . The handle position 26 is an inclined surface or a curved surface recessed on the side wall of the water outlet 21 , which facilitates the buckling of the auxiliary cover 2 .

[0056] 1 to 7 , a first embodiment of the present invention is shown.

[0057] In the first embodiment, the auxiliary cover 2 and the main cover 1 are axially limited by a snap-fit ​​connection. Specifically, the lower surface of the auxiliary cover 2 is provided with at least one snap 27, and the upper surface of the main cover 1 is provided with an arcuate snap groove 18 for the snap 27 to engage and flexibly engage. The arc shape of the arcuate snap groove 18 provides space for the snap 27 to flexibly engage when the auxiliary cover 2 rotates, while also limiting the rotation angle of the auxiliary cover 2.

[0058] In the first embodiment, there are two buckles 27 , which are centrally symmetrical with the axis of the auxiliary cover 2 as the center line. Correspondingly, there are also two arc-shaped buckle grooves 18 on the main cover 1 .

[0059] 8 to 13 , a second embodiment of the present invention is shown.

[0060] In the second embodiment, the auxiliary cover 2 and the main cover 1 are axially limited by magnetic attraction. Specifically, the opposing surfaces of the auxiliary cover 2 and the main cover 1 are provided with magnets or magnets and metal sheet components.

[0061] In the second embodiment, the opposing surfaces of the main cover 1 and the auxiliary cover 2 are respectively provided with a first mounting groove 19 and a second mounting groove 28 for engaging the first magnet 3 and the second magnet 4. The first magnet 3 and the second magnet 4 are respectively secured within the first mounting groove 19 and the second mounting groove 28 by a first sealing body 5 and a second sealing body 6. The first sealing body 5 and the second sealing body 6 isolate the first magnet 3 and the second magnet 4 from contact with water. Two first magnets 3 are provided for each second magnet 4. The positions of the two first magnets 3 correspond to the open and closed states of the auxiliary cover 2 relative to the main cover 1, respectively. This ensures that the auxiliary cover 2 has a corresponding first magnet 3 that attracts the second magnet 4 in either the open or closed state, thereby preventing the auxiliary cover 2 from falling. Alternatively, the first magnet 3 can be designed to be elongated or curved to attract the second magnet 4 at all positions.

[0062] 14 , the above-mentioned cup cover structure can be applied to containers 7 including but not limited to stainless steel cups, enamel cups, and glass cups that can be used to hold water.

[0063] 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.
