Description

Technical Field

[0001] The present invention relates to the technical field of container plugs, and in particular to a container plug that can be opened and closed quickly. Background Art

[0002] At present, most containers or bottles on the market are generally sealed with threaded or rubber stoppers, which have many defects:

[0003] (1) The bottle stopper needs to be rotated several times to open and close, which is cumbersome and time-consuming.

[0004] (2) The sealing is not good. There is a problem of leakage due to failure to tighten completely. The liquid in the container can easily leak into the gaps of the sealing ring or other parts of the bottle stopper, making it difficult to clean. For example, the rubber stopper requires special tools to open. The bottle stopper is disassembled and cleaned many times, resulting in a short service life.

[0005] (3) The rubber stopper relies on the friction generated by the elastic rubber stopper and the container wall to resist the liquid pressure in the container and the external force of opening. The liquid pressure in the container and the external force of opening that it can withstand are relatively small.

[0006] Taking thermos bottles (cups) that are more commonly used in daily life as an example, if the driver wants to open the cork to drink water while people are driving and waiting at traffic lights, the driver cannot do it alone (if the driver uses both hands to open the cork, when the green light comes on, he may not be able to shift gears and operate the steering wheel in time, which may easily cause traffic jams). The same is true in sports occasions or other occasions where you cannot pause or free your hands. For another example, when brewing beverages in ordinary thermos bottles (cups), the beverages will leak into the gaps in the sealing sleeve, making it difficult to clean.

[0007] Therefore, there is an urgent need on the market for a container plug that can solve one or more of the above problems. Summary of the invention

[0039] In some embodiments, the housing 3 is provided with at least two through holes matching the buttons 2 - 4 .

[0044] Implementation process: Quick start:

[0045] When the container plug is in the closed state, that is, the container mouth is tightly plugged, quick opening is achieved through the following operations:

[0046] When the two buttons are pressed at the same time (one-hand operation is possible), the button stops moving downward when the bottom of the button touches the button limit block on the top surface of the annular support frame. The button limit block limits the displacement of the conical polygonal plug body in the axial direction. At this time, the force will be transmitted to the conical polygonal plug body through the lever mechanism composed of the straight connecting rod and the "L"-shaped connecting rod, pushing the conical polygonal plug body to move axially downward, thereby driving the sliding block to shrink radially, and the annular elastic sealing sleeve loses the extrusion force of the sliding block, returns to a relaxed state, detaches from the inner wall of the container, and the seal is opened. At this time, the hollow protruding part in the middle of the upper cover changes its position in the columnar bottom block of the rigid spring component. At first, it is stuck in the middle annular groove. As the conical polygonal plug body moves downward, it slowly moves to the highest point between the two annular grooves. When it moves to the highest point, the two petals of the columnar bottom blocks move inward toward each other and undergo elastic deformation, and then continue to move to the tail annular groove and get stuck. The two petals of the columnar bottom blocks also return to their original state, and then the container plug can be taken out stably and easily.

[0047] It should be noted that the sliding block will retract radially because a guide groove is provided on the conical polygonal plug body, and the sliding block matching the guide groove will move relative to the guide groove to form an inwardly retracted structure.

[0048] Quick Closure:

[0049] When the container stopper has been opened and removed from the container mouth, quick closure is achieved by the following operations:

[0050] Insert the container plug into the container mouth. At this time, the shell just covers the bottle mouth. Press the thumb on the shell and the index finger on the inner side of the upper end of the handle. Squeeze it with a little force and the handle will move upward, thereby driving the conical polygonal plug body to move upward. When the top of the handle touches the shell, the conical polygonal plug body stops moving upward. The shell limits the displacement of the conical polygonal plug body in the axial direction, thereby driving the sliding block to expand radially outward. The annular elastic sealing sleeve also expands and deforms outward under the push of the sliding block, close to the inner wall of the container mouth, and can withstand a certain separation force. At this time, the middle of the upper cover is hollowed out. The position of some of the protruding parts in the columnar bottom block of the rigid spring component has changed. At first, it is stuck in the tail annular groove. With the upward movement of the conical polygonal plug body, it slowly moves to the highest point between the two annular grooves. When it moves to the highest point, the two halves of the columnar bottom block move inward toward each other and undergo elastic deformation. Then, it continues to move to the middle annular groove and gets stuck. The two halves of the columnar bottom block also return to their original state, achieving a stable sealing effect. At this time, the upward force of the upper cover will be transmitted to the button through the lever mechanism composed of the straight connecting rod and the "L"-shaped connecting rod, and the button moves upward to return to its original state.

[0051] In summary, the present invention includes: a plug assembly 1, which is used to be inserted into the container port; a switch assembly 2, which is fixedly connected to the plug assembly 1 and is used to control the plug assembly 1 to move downward to open or move upward to close; a shell 3, which is sleeved on the outer periphery of the switch assembly 2, and the bottom of the inner wall of the shell 3 is fixedly connected to the plug assembly 1; and an elastic sealing sleeve 4, which is sleeved on the outer periphery of the plug assembly 1 and is fixedly connected to the bottom of the shell 3. The above design is adopted to achieve convenient and fast operation, good sealing performance, easy cleaning, single-handed operation, and application in various occasions. The present invention has strong practicality, simple structure, low manufacturing cost, and is easy to promote and use.
