Description

A cup lid that opens and closes with a push button Technical Field

[0001] The utility model relates to a cup cover that can be opened and closed by pressing, and belongs to the technical field of thermos cups. Background Art

[0002] Cups are essential items in people's daily lives. They can be categorized into various types based on their purpose, such as water cups, coffee cups, hot drink cups, and thermos cups. Taking thermos cups as an example, thermos cups are generally made of materials such as ceramic, stainless steel, or titanium alloy. They feature a vacuum layer inside the cup body and a sealed lid on top. This vacuum layer insulates the water or other liquids contained within the container from the outside world, achieving the purpose of heat preservation or cooling. The internal structure of a thermos cup typically consists of multiple layers. The vacuum layer is used to prevent heat conduction, and the outer wall of the vacuum layer is plated with silver to prevent heat radiation. A thermos cup typically includes a cup liner, an outer shell, and a lid.

[0003] Conventional cup lids typically open by securing the lid to the cup body via a threaded connection, which offers a simple structure and reliable connection. However, this threaded connection requires the user to use both hands to remove the lid, which can be inconvenient in some situations. Furthermore, the user must repeatedly tighten or loosen the lid before and after each use, significantly reducing closing and opening efficiency.

[0004] Currently, there is a push-on cup lid (CN 206062786 U). It includes a push-on portion, a sliding portion slidably connected to the push-on portion via a tapered surface, allowing it to move away from the push-on portion when the push-on portion moves downward, and an elastic band acting on the sliding portion. The elastic band acts on the two sliding portions, causing them to tend toward each other. A hook portion is provided on the side of the sliding portion closest to the push-on portion. During use, pressing the push-on portion causes the sliding portion to slide, causing the hook portion to move away from the cup body, allowing the entire cup lid to be removed and then used to drink or pour water through the cup opening. The difference between this utility model and the aforementioned patent document is that the elastic band in the aforementioned patent document will stretch over time. Assembly is difficult because the sliding portion must be placed first and then the elastic band. This installation process causes the sliding portion to warp, and the button to also warp when installed. There is also an outer cover to press, making assembly difficult. Furthermore, there is no detent point for pushing the sliding portion open or returning it to its original position. Utility Model Content

[0005] The utility model proposes a cup cover that can be opened and closed by pressing a first linkage surface and a second linkage surface, which is reset by a first spring, and the exhaust valve can adjust the gap between the exhaust valve and the second mounting plate by a hook to adjust the heat preservation effect of the cup, thereby solving the problems existing in the prior art.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] A cup cover that opens and closes by pressing, comprising a cup cover assembly, a pressing assembly mounted on the cup cover assembly, and a cup body; the cup cover comprises a lower cup cover in a hollow cylindrical shape;

[0008] The lower cup cover includes an outer wall of the lower cup cover, a first mounting plate, and a third support column mounted on the first mounting plate; a limiting groove is formed between the outer wall of the lower cup cover and the first mounting plate; the limiting groove leaves space for the locking assembly to move left and right;

[0009] The lower cup cover is provided with a plurality of locking assemblies, the locking assemblies comprising a first vertical member, a horizontal member mounted on the third support column, and a second vertical member connected in sequence, the second vertical member being located in the limiting groove and provided with a hook;

[0010] A first linkage surface is installed on the side of the first vertical member facing the pressing assembly, a first spring is installed on one side of the locking assembly, and the other side opposite to the first spring is installed on the outer wall of the lower cup cover or the first mounting plate;

[0011] The pressing assembly is equipped with a second linkage surface that cooperates with the first linkage surface during the downward pressing process to push the locking assembly outward to separate the cup cover and the cup body, and the first spring returns to push the first linkage surface inward to move the pressing assembly upward during the resetting process.

[0012] The first linkage surface is provided with a first groove, the second linkage surface is provided with a first protrusion matching the first groove, and the second linkage surface and the first linkage surface are mutually matched inclined surfaces or arc surfaces.

[0013] In one case, a third support column is installed on the outer wall of the lower cup cover, a first connecting column is installed on the other side opposite to the first vertical member, and a second connecting column is installed on the third support column. The first connecting column and the second connecting column are sleeved with a first spring that passes through the second vertical member.

[0014] In another case, a third supporting column is installed on the first mounting plate, a first connecting column is installed on the other side opposite to the first vertical member, a second connecting column is installed on the third supporting column, and the first connecting column and the second connecting column are sleeved with a first spring.

[0015] The first mounting plate defines a first mounting hole, into which a second mounting plate is mounted. An elastic ring is installed between the second mounting plate and the first mounting plate. An annular ring is provided on the side of the second mounting plate facing the cup body, which mates with the convex cup opening. The elastic ring and the second mounting plate are made of elastic silicone rings. When the cup opening is opened, there is a certain margin between the second mounting plate and the cup opening, facilitating opening.

[0016] The second mounting plate is provided with a second mounting hole for mounting an exhaust valve. The exhaust valve comprises an exhaust valve body. A metal block is mounted on the upper end of the exhaust valve body. A first magnet adsorbed to the metal block is mounted on the lower end of the pressing assembly.

[0017] The exhaust valve has two functions:

[0018] When the pressing component is pressed down, the exhaust valve will move downward to achieve synchronous exhaust;

[0019] The pull hook can pull down the exhaust valve under human action, thereby reducing the thermal insulation effect of the entire thermos cup. In some cases (in summer or when the weather is hot, the temperature of the hot water in the thermos cup is difficult to reduce for a long time, which is not suitable for users to drink water. The thermos cup involved in this technology can adjust the thermal insulation effect according to human needs. The thermal insulation effect is best when the exhaust valve is sealed with the first mounting plate. The thermal insulation effect will be reduced after the exhaust valve is pulled down, which is suitable for users to use in summer). It has a better effect and has the function of adjusting the thermal insulation effect.

[0020] The pressing assembly includes an outer pressing body and a central column. The outer pressing body is configured as a small upper portion and a large lower portion. The second mounting plate further includes a second support column disposed on the second mounting plate body and a first support column for connecting to the first mounting plate. The outer pressing body, configured as a small upper portion and a large lower portion, prevents the pressing assembly from detaching from the cup lid assembly.

[0021] The exhaust valve also includes a second expanding ring mounted below the exhaust valve body and a first expanding ring mounted above the exhaust valve body. A retractor hook is connected to the lower end of the exhaust valve body. The second and first expanding rings prevent the exhaust valve body from separating from the second mounting plate. The retractor hook can adjust the distance between the metal block and the first magnet.

[0022] The lower end of the central column is equipped with a first magnet, and the central column abuts against the exhaust valve body through the metal block and the first magnet. The central column of the pressing assembly abuts against the exhaust valve, so that the pressing assembly can only move up and down at a limited position.

[0023] The upper cup cover is also equipped with an unlocking assembly for limiting or permitting the movement of the locking assembly. The unlocking assembly includes an annular ring located inside the upper cup cover and can be easily rotated by the user, an unlocking head installed on the annular ring (unlocking and locking marks are engraved on the upper cup cover), an unlocking rod installed under the annular ring, and a limit block provided on the locking assembly and cooperating with the unlocking rod to limit or permit the movement of the locking assembly. The unlocking rod is above the locking assembly and is blocked by the limit block and cannot move outward, which is a restricted locking state. The unlocking rod is not above the locking assembly and is not blocked by the limit block and can move outward, which is a permitted unlocking state.

[0024] The cup body is provided with a cup mouth assembly, which includes a concave cup mouth and a convex cup mouth from bottom to top, and the concave cup mouth matches the hook. The separation and connection of the concave cup mouth and the hook realize the opening and closing of the cup cover and the cup body.

[0025] The utility model relates to a cup lid that can be opened and closed by pressing. When the user presses down the pressing component with force, the first linkage surface and the second linkage surface push the locking component outward, and the hook is separated from the concave cup mouth, so that the cup lid and the cup body are separated. When the user releases the pressing component, the first spring returns to its original position and pushes the first linkage surface to move inward to cooperate with the second linkage surface during the resetting process of the pressing component, so that the pressing component moves upward and the cup lid is opened and closed. The first linkage surface and the second linkage surface are used to realize the opening and closing of the cup lid, and the exhaust valve can adjust the heat preservation effect of the cup by adjusting the gap between the exhaust valve and the second mounting plate through the pull hook.
