[0002] A pull-ring plastic combination cap is a plastic cap that is opened and closed by pulling a pull ring. Generally, a combination cap can seal the mouth of a bottle of a specific size, but cannot seal the mouth of a bottle of different diameters. By providing the combination cap with an adjustable structure to seal bottles of different mouth diameters, the unified production of bottle caps can be achieved, reducing the number of production lines.

[0003] The defects of existing plastic covers are:

[0004] 1. US4279353A discloses a plastic bottle cap, which discloses a tamper-proof plastic bottle cap for assembling to a bottle neck with a bead. The bottle cap does not have a structure for closing the bottle openings of bottles with different diameters and cannot close the bottle openings of different diameters. Therefore, a pull-ring type plastic combination cap that can close the bottle openings of bottles with different diameters and is suitable for various bottle types is needed to solve this problem.

[0005] 2. JP2006143321A discloses a plastic bottle cap with a retaining function. This patent discloses a bottle cap in which the middle cap can be firmly retained on the main body of the plastic bottle. The bottle cap does not have a structure for protecting the bottle cap and objects on the bottle cap. When the bottle cap is hit, the bottle cap is easily damaged, thereby causing damage to the bottle cap. Therefore, a pull-ring type plastic combination cap suitable for various bottle types is needed to solve this problem, which can protect the bottle cap and parts on the bottle cap to reduce damage to the bottle cap.

[0006] 3. JP2015009853A discloses a plastic bottle cap and a capped polyester bottle. This patent discloses providing a plastic cap with excellent wind-tightening performance and cap-opening performance, and can show excellent sealing performance even when applied to a plastic bottle with a damaged end at the mouth. The bottle cap does not have a structure for detecting the sealing performance. When the bottle cap is covered on the outside of the bottle, people cannot detect if the bottle cap leaks, which causes the internal contents of the bottle to deteriorate due to poor sealing. Therefore, a pull-ring type plastic combination cap suitable for various bottle types is needed to detect the sealing performance between the bottle cap and the bottle to solve this problem.

[0007] 4. CN116392390B discloses a polypropylene combination cap for a ring-pull plastic infusion container and a method for using the same. This patent discloses a combination cap that is easy to assemble and disassemble, but does not have an alarm function and cannot sound an alarm when air leaks between the bottle and the bottle cap. This makes it impossible for people to know whether the bottle cap can effectively seal the bottle. Therefore, a ring-pull plastic combination cap that can sound an alarm when air leaks between the bottle and the bottle cap and is applicable to various bottle types is needed to solve this problem.

[0016] Preferably, the anti-collision system includes a protective frame, a frame plate, a push rod, a second anti-slip plate and a guide groove. The protective frame is movable on the outside of the bottle cap body. The frame plates are symmetrically installed on both sides of the protective frame. The push rod is movably installed through one side of the frame plate. The second anti-slip plates are symmetrically installed on both sides of the push rod. The guide grooves are symmetrically opened on the inner side of the protective frame.

[0017] Preferably, the intelligent alarm system includes an alarm unit, a timing unit, a control unit, a numerical calculation unit, a box body, a power supply unit and a box cover.

[0018] Preferably, the method of using the pull-ring type plastic combination cover applicable to various bottle types is as follows:

[0019] S1. First, pull the circular ring upward to drive the closing plate to move up, and at the same time, pull the second pull rod upward to drive the pressure measuring unit to move upward, so that the sealing bag shrinks upward, and the bottle cap body is put on the bottle mouth position, and then the bottle mouth is pressed against the bottom of the sealing gasket at the bottom of the closing plate, and then the circular ring is released. The first elastic unit exerts downward pressure on the lifting plate, driving the lifting plate to move downward, and then driving the second elastic unit to move downward. The second elastic unit exerts downward force on the closing plate, so that the bottom of the sealing gasket is tightly attached to the top of the bottle mouth, and at the same time, the inclined block moves downward with the downward movement of the lifting plate, and the inclined block is inserted into the interior of the moving frame. The downward movement of the inclined surface of the inclined block can squeeze the moving frame inward, so that the engaging teeth on the moving frame are inserted into the inner side of the thread on the outside of the bottle mouth, thereby fixing the bottle cap body to the outside of the bottle mouth of bottles with different diameters;

[0020] S2. Then, the protective frame is moved upward, and one end of the interlocking rod is inserted into the holes on both sides of the protective frame, thereby fixing the protective frame so that the protective frame can protect the components on the top of the bottle cap body;

[0021] S3. Then release the second pull rod, and the fourth elastic unit applies a downward force to the pull block, causing the second pull rod to move downward, thereby causing the pressure measuring unit to move downward, causing the sealing bag to stretch, thereby causing the sealing bag to compress the air inside the bottle, and the compressed air inside the bottle to apply pressure to the sealing bag, and then apply pressure to the pressure measuring unit. The value of the pressure measuring unit at this time is N1, and then the pressure value measured by the pressure measuring unit is N2. The numerical calculation unit performs the operation of N2-N2. When the pressure value N2-N2≥5, the result is sent to the control unit. The control unit controls the timing unit to start timing, and the timing value is set to T. At the same time, the numerical calculation unit performs the operation T / 300. When the value of T / 300 is an even number, the control unit controls the alarm unit to sound an alarm, thereby achieving intermittent alarms, avoiding the alarm unit from sounding an alarm when people are not around, causing waste of electricity.

[0022] Preferably, the step S3 further includes the following steps:

[0023] S31. When the personnel finds the alarm of the alarm unit, they pull the first pull rod upward to drive the lifting plate to move upward, thereby driving the inclined block to move upward, and then the movable frame is released. The movable frame moves outward under the elastic force of the fifth elastic unit, so that the engaging teeth leave the thread gap of the bottle mouth, thereby facilitating the removal of the bottle cap body from the bottle mouth.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention causes the first pull rod and the lifting plate to move downward, thereby driving the second elastic unit to move downward. The second elastic unit applies a downward force to the closing plate, so that the bottom of the sealing gasket is tightly attached to the top of the bottle mouth. At the same time, the inclined block moves downward as the lifting plate moves downward, and the inclined block is inserted into the interior of the movable frame. The downward movement of the inclined surface of the inclined block can squeeze the movable frame inward, so that the engaging teeth on the movable frame are inserted into the inner side of the thread on the outside of the bottle mouth, thereby fixing the bottle cap body to the outside of the bottle mouth of bottles with different diameters, so that the pull-ring type plastic combination cap suitable for various bottle types can fix the bottle cap body to the outside of the bottle mouth of bottles with different diameters.

[0026] 2. The present invention fixes the protective frame by moving the protective frame upward and inserting one end of the interlocking rod into the holes on both sides of the protective frame, thereby enabling the protective frame to protect the components on the top of the bottle cap body. The pull-ring type plastic combination cover suitable for various bottle types is fixed by moving the protective frame upward and inserting one end of the interlocking rod into the holes on both sides of the protective frame, thereby enabling the protective frame to protect the components on the top of the bottle cap body.

[0027] 3. According to the present invention, before the bottle cap body is installed at the bottle mouth, the second pull rod is first moved upward to drive the sealing bag to shrink. Then, when the bottle cap body is installed at the bottle mouth, the second pull rod is released, and the fourth elastic unit applies a downward force to the second pull rod, thereby causing the second pull rod to move downward and the sealing bag to stretch, thereby compressing the air inside the bottle. The compressed air will in turn exert pressure on the sealing bag and transmit the pressure to the pressure measuring unit through the pressure plate and the third elastic unit. Then, the pressure measuring unit can measure the gas pressure inside the bottle. When the bottle leaks, the pressure drops, and it can be determined whether the bottle is leaking. The pull-ring type plastic combination cap suitable for various bottle types can measure the internal gas pressure of the bottle using the combination cap through components such as the sealing bag and the pressure measuring unit, and then determine whether the bottle is leaking based on the pressure change.

[0028] 4. The present invention can sound an alarm when there is gas leakage inside the bottle using the combination cover, and can stop the alarm after the alarm is set for a time, and can continue to sound the alarm a specific time after stopping the alarm, thereby avoiding the waste of electricity caused by continuous alarms when no one is around. The pull-ring type plastic combination cover suitable for various bottle types can sound an alarm when there is gas leakage inside the bottle using the combination cover, and can stop the alarm after the alarm is set for a time, and can continue to sound the alarm a specific time after stopping the alarm, thereby avoiding the waste of electricity caused by continuous alarms when no one is around.

[0059] S1. First, pull the ring 4 upward to drive the closing plate 8 to move upward, and at the same time, pull the second pull rod 14 upward to drive the pressure measuring unit 11 to move upward, so that the sealing bag 10 shrinks upward, and the bottle cap body 1 is put on the bottle mouth position, and then the bottle mouth is pressed against the bottom of the sealing gasket 9 at the bottom of the closing plate 8, and then the ring 4 is released. The first elastic unit 6 exerts downward pressure on the lifting plate 5, driving the lifting plate 5 to move downward, and then drives the second elastic unit 7 to move downward.

[0060] S2. Then, the protective frame 25 is moved upward, and one end of the engaging rod 24 is inserted into the holes on both sides of the protective frame 25, thereby fixing the protective frame 25 so that the protective frame 25 can protect the components on the top of the bottle cap body 1;

[0061] S3. Then, the second pull rod 14 is released, and the fourth elastic unit 16 applies a downward force to the pull block 15, causing the second pull rod 14 to move downward, thereby causing the pressure measuring unit 11 to move downward, causing the sealing bag 10 to expand, thereby causing the sealing bag 10 to compress the air inside the bottle. The compressed air inside the bottle applies pressure to the sealing bag 10, and then applies pressure to the pressure measuring unit 11. The value of the pressure measuring unit 11 at this time is N1. Subsequently, the pressure value measured by the pressure measuring unit 11 is N2. The numerical calculation unit 33 performs the operation of N2-N2. When the pressure value N2-N2≥5, the result is sent to the control unit 32. The control unit 32 controls the timing unit 31 to start timing, and the timing value is set to T. At the same time, the numerical calculation unit 33 performs the operation T / 300. When the value of T / 300 is an even number, the control unit 32 controls the alarm unit 30 to sound an alarm, thereby achieving intermittent alarms, thereby avoiding the alarm unit 30 from sounding an alarm all the time when people are not around, causing waste of electricity.

[0062] S3 also includes the following steps:

[0063] S31. When the personnel finds the alarm of the alarm unit 30, they pull the first pull rod 3 upward to drive the lifting plate 5 to move upward, thereby driving the inclined block 17 to move upward, and then the movable frame 18 is released. The movable frame 18 moves outward under the elastic force of the fifth elastic unit 21, so that the engaging teeth 19 leave the thread gap of the bottle mouth, thereby facilitating the removal of the bottle cap body 1 from the bottle mouth.

[0064] Working principle: Before using the pull-ring type plastic combination cover suitable for various bottle types, you should first check whether there are any problems that affect the use of the pull-ring type plastic combination cover suitable for various bottle types. First, pull the ring 4 upward to drive the closing plate 8 to move upward, and at the same time pull the second pull rod 14 upward to drive the pressure measuring unit 11 to move upward, so that the sealing bag 10 shrinks upward, put the bottle cap body 1 on the bottle mouth, and then make the bottle mouth press against the bottom of the sealing gasket 9 at the bottom of the closing plate 8, and then loosen the ring 4. The first elastic unit 6 applies downward pressure to the lifting plate 5, driving the lifting plate 5 to move downward, and then driving the second elastic unit 7 to move downward. The second elastic unit 7 exerts downward pressure on the sealing The closing plate 8 applies a downward force, so that the bottom of the sealing gasket 9 is tightly attached to the top of the bottle mouth. At the same time, the inclined block 17 moves downward as the lifting plate 5 moves downward, and the inclined block 17 is inserted into the inside of the moving frame 18. The inclined surface of the inclined block 17 moves downward to squeeze the moving frame 18 inward, so that the engaging teeth 19 on the moving frame 18 are inserted into the inner side of the thread on the outside of the bottle mouth, thereby fixing the bottle cap body 1 to the outside of the bottle mouth of bottles with different diameters. Then, the protective frame 25 is moved upward, and one end of the engaging rod 24 is inserted into the holes on both sides of the protective frame 25, thereby fixing the protective frame 25, so that the protective frame 25 can protect the components on the top of the bottle cap body 1, and then release the first The second pull rod 14 and the fourth elastic unit 16 exert a downward force on the pull block 15, causing the second pull rod 14 to move downward, thereby causing the pressure measuring unit 11 to move downward, causing the sealing bag 10 to stretch, thereby causing the sealing bag 10 to compress the air inside the bottle. The compressed air inside the bottle exerts pressure on the sealing bag 10, and then exerts pressure on the pressure measuring unit 11. The value of the pressure measuring unit 11 at this time is N1, and then the pressure value measured by the pressure measuring unit 11 is N2. The numerical calculation unit 33 performs the calculation of N2-N2. When the pressure value N2-N2 ≥ 5, the result is sent to the control unit 32. The control unit 32 controls the timing unit 31 to start timing. The timing value is set to T, and the numerical calculation unit 33 performs the calculation T / 300. When the value of T / 300 is an even number, the control unit 32 controls the alarm unit 30 to sound an alarm, thereby realizing intermittent alarms, and avoiding the alarm unit 30 from sounding an alarm all the time when the personnel are not present, thereby wasting electricity. When the personnel finds the alarm of the alarm unit 30, they pull the first pull rod 3 upward to drive the lifting plate 5 to move upward, thereby driving the inclined block 17 to move upward, and then the movable frame 18 is released. The movable frame 18 moves outward under the elastic force of the fifth elastic unit 21, thereby causing the engaging teeth 19 to leave the thread gap of the bottle mouth, thereby facilitating the removal of the bottle cap body 1 from the bottle mouth.
