Summary of the Invention

[0004] The purpose of the present invention is to provide a push-type cup lid and a method of using the same, which has an ingenious structure and can connect to the outside to balance the air pressure before opening the lid, thereby solving the problem of difficult lid opening. The lid also has a locking structure to avoid safety accidents caused by accidental opening of the lid.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions.

[0006] Technical solution 1: A push-type cup lid is provided with a button, a lid body, and a push piece from top to bottom in sequence; a drinking port and an installation port that penetrate up and down are respectively provided at the edge and the middle of the lid body; the button and the push piece pass through the installation port and are connected by a buckle, and pressing and pushing the button can drive the push piece to move back and forth, thereby opening and closing the drinking port and the installation port; a fixing part is provided below the drinking port of the lid body, and one end of the push piece is provided with a plug-in part inserted into the fixing part for fixing the push piece; a first blocking part is provided on the lower surface of the lid body on the side away from the drinking port of the installation port, and a second blocking part is correspondingly provided on the push piece, and there is a gap between the button and the upper surface of the lid body; when the button is pressed downward, the end of the push piece away from the plug-in part moves downward and disengages from the lid body, the installation port is opened for exhaust, and the first blocking part and the second blocking part are misaligned and separated, and the cup lid is in an exhaust unlocking state. At this time, sliding the button to the right can make the push piece move to the right to open the drinking port; when the button is released, the push piece moves upward and fits tightly against the lid body to close the installation port, and the first blocking part and the second blocking part are aligned to limit the push piece from moving to the right, and the cup lid is in a locked and closed state.

[0007] Adopting the above technical solution, by setting the first blocking part and the second blocking part, the push piece is restricted from moving to the right by default; and the button is set with a gap from the lid body, and only one end of the push piece, the plug-in part, is fixed by the fixing part, so that the other end of the push piece can be pressed by the button and move downward to disengage from the lid body, which can simultaneously achieve exhaust pressure relief and release the lock on the push piece; that is to say, the push piece must be pressed by the button before it can move, which can ensure that the cup lid will not be accidentally touched to open the drinking port and cause safety accidents such as scalding the user with hot water. At the same time, it can also synchronously achieve exhaust pressure relief and solve the problem that it is not easy to open the cup lid due to excessive pressure. Based on the ingenious setting of the above structure, the operation efficiency of exhaust and opening the lid is very high.

[0008] Preferably, the push piece includes a push plate and a seal, and is integrally formed by overmolding; the seal is made of an elastic material and includes a drinking port sealing part and an installation port sealing part, which are respectively used for sealing the drinking port and the installation port; the second blocking part is arranged on the push plate.

[0009] Adopting the above technical solution, the push plate and the seal are integrally formed by overmolding, reducing the number of parts, and can also make the connection between the push plate and the seal more firm, which is beneficial to extending the service life of the push piece that moves back and forth continuously; the drinking port sealing part and the installation port sealing part are separately arranged, which can make the sealing performance better and will not affect each other.

[0010] Preferably, a limiting convex part is provided on the outer edge of the installation port sealing part, and a limiting groove is correspondingly provided on the push plate, and the limiting convex part and the limiting groove are in concave-convex fit.

[0011] With the above technical solution, by providing a concave-convex fit between the limiting convex part and the limiting groove, the connection strength between the push plate and the seal can be further enhanced.

[0012] Preferably, both the drinking port sealing part and the mounting port sealing part surround and seal the drinking port and the mounting port by closely contacting the lower surface of the cover body through a ring of upwardly protruding ribs.

[0013] With the above technical solution, by providing both the drinking port sealing part and the mounting port sealing part as ribs, the flexibility and sealing performance are better compared to others.

[0014] Preferably, two insert pieces with reverse buckles are symmetrically arranged below the button to form a snap-fastener; limiting holes are correspondingly and symmetrically arranged in the slots on the push plate; the reverse buckles on the snap-fastener cooperate with the limiting holes to connect the button and the push piece in a snap-fastening manner.

[0015] With the above technical solution, by providing a snap-fastener and a slot, and the reverse buckles on the snap-fastener are connected in cooperation with the limiting holes on the slot, the structure is simple and effective; and since the snap-fastener is composed of two symmetrically arranged insert pieces, it has a certain flexibility and can support being pulled out from the slot, realizing detachability and facilitating the cleaning of the cup lid.

[0016] Preferably, two hooks are symmetrically arranged below the drinking port of the cover body to form a fixing part; one end of the push plate and the drinking port sealing part are combined to form a plug-in part, and the plug-in part is inserted into the fixing part, so that the seal tightly adheres to the cover body to seal the drinking port and the mounting port.

[0017] With the above technical solution, by providing two hooks to form a fixing part, the structure is simple and the cost is low.

[0018] Technical solution 2: A method for using a push-piece type cup lid, comprising the following steps:

[0019] S1: After pouring hot water into the water cup, screw the cup lid onto the water cup to seal the cup mouth; the plug-in part of the push piece is inserted into the fixing part, and the steam in the cup and the fixing part make the drinking port sealing part and the mounting port sealing part closely contact the lower surface of the cover body to seal the drinking port and the mounting port; meanwhile, the first blocking part and the second blocking part are in relative positions, restricting the push piece from moving to the right to open the drinking port; at this time, the cup lid is in a locked and closed state;

[0020] S2: Press the button downward, and the button forces the end of the push piece away from the plug-in part to move downward, so that the mounting port sealing part is separated from the cover body, and the drinking port sealing part seals the drinking port under the action of the fixing part. At this time, the inside and outside of the cup are communicated through the mounting port, and the steam pressure in the cup is exhausted and relieved outward through the mounting port. Meanwhile, the first blocking part and the second blocking part are misaligned and separated, and the push piece can move to the right without restriction. At this time, the cup lid is in an exhaust and unlocking state;

[0021] S3: Continue to press the button downward and push it to the right. The button drives the push piece to move to the right, and the sealing part of the drinking port moves to the right to release the sealing of the drinking port. At this time, the cup lid is in the open state, the drinking port is connected to the inside of the cup, and the water in the cup can be poured out from the drinking port;

[0022] S4: Press the button downward and push it to the left. The button drives the push piece to move to the left, and the sealing part of the drinking port resets to the left to re-seal the drinking port; after releasing the button, the push piece is reset upward under the action of the fixing part to resume close contact with the lower surface of the lid body, and the sealing part of the installation port re-seals the installation port; and the first blocking part and the second blocking part are in relative positions to limit the push piece from moving to the right; at this time, the cup lid resumes the locked and closed state again.

[0023] With the above technical solution, the movement of the push piece must be after pressing the button, which can ensure that the cup lid will not accidentally open the drinking port and cause safety accidents such as scalding users with hot water. At the same time, it can also synchronously achieve exhaust and pressure relief, solving the problem that it is difficult to open the cup lid due to excessive pressure. Through ingenious settings, the operation efficiency of exhaust and opening the lid is very high.

[0024] Compared with the prior art, the beneficial effect of the present invention is: with the above technical solution, by setting the first blocking part and the second blocking part, the push piece is restricted from moving to the right by default; and the button is set with a gap between the lid body, and only one end of the push piece is fixed by the fixing part, which can make the other end of the push piece be pressed downward by the button to move away from the lid body, and can simultaneously achieve exhaust and pressure relief and release the lock of the push piece; that is to say, the movement of the push piece must be after pressing the button, which can ensure that the cup lid will not accidentally open the drinking port and cause safety accidents such as scalding users with hot water. At the same time, it can also synchronously achieve exhaust and pressure relief, solving the problem that it is difficult to open the cup lid due to excessive pressure. Through ingenious settings, the operation efficiency of exhaust and opening the lid is very high. BRIEF DESCRIPTION OF THE DRAWINGS
