Technical Field

[0001] The invention relates to an automatic quantitative liquid discharging cover and a use method thereof. Background Art

[0002] Bottles for storing liquids are generally equipped with bottle caps, which are generally threadedly connected to the mouth of the bottle. To pour out the liquid in the bottle, you need to first unscrew the bottle cap from the mouth of the bottle, and then pour the liquid in the bottle into a cup. When pouring liquid, the mouth of the bottle needs to be tilted downward or inverted, and the bottle needs to be held firmly. However, children often hold the bottle unsteadily when pouring liquid, and may accidentally pour out too much liquid, or even pour out all the liquid in the bottle at once. Therefore, it is best to design a bottle cap that is installed on the mouth of the bottle, so that the liquid inside the bottle can be poured out without removing the bottle cap, and the liquid inside the bottle can be prevented from being poured out all at once.

[0005] Preferably, the piston has a built-in weight block.

[0006] Preferably, the weight block is in the shape of a ring or a disk, and the weight block is coaxial with the piston.

[0007] Preferably, the end plug is disc-shaped, and the end plug is coaxial with the piston.

[0008] Preferably, the connecting rod is coaxial with the piston.

[0009] Preferably, the support frame comprises a plurality of support arms, the plurality of support arms are evenly distributed along the circumferential direction of the outer peripheral wall of the connecting rod, and the plurality of support arms are respectively arranged along the radial direction of the outer peripheral wall of the connecting rod.

[0010] Preferably, the distance between the support frame and the end plug is smaller than the distance between the liquid outlet and the annular convex edge.

[0011] Preferably, the liquid pouring tube is coaxial with the main cover body.

[0012] Preferably, the first end of the liquid pouring tube is located inside the main cover body.

[0013] The present invention also provides a method for using the above-mentioned automatic quantitative liquid discharging cover, comprising:

[0014] Take a bottle containing liquid, and install the main cover body on the bottle mouth (the main cover body is threadedly connected to the bottle mouth);

[0015] When it is not necessary to pour out the liquid in the bottle, the bottle is placed upright, with the bottle mouth facing upward and the liquid outlet of the pouring tube facing upward; the piston, connecting rod, support frame and end plug move downward under the action of gravity until the support frame is supported on the annular convex edge; at this time, the end plug moves downward to the bottom of the pouring tube, the inner cavity of the bottle is connected with the inner cavity of the pouring tube, and the piston moves downward to the bottom of the liquid outlet of the pouring tube, the piston separates the liquid outlet of the pouring tube from the inner cavity of the bottle, so that the liquid inside the bottle is separated from the environment outside the liquid outlet of the pouring tube;

[0016] When it is necessary to pour out the liquid in the bottle, the bottle is turned upside down, the bottle mouth is tilted downward, and the liquid outlet of the pouring tube is downward; the liquid in the bottle continues to flow into the pouring tube; the end plug, the connecting rod, the support frame and the piston move downward under the action of gravity and the pressure of the liquid inside the bottle; and when the piston moves down to the liquid outlet of the pouring tube, the liquid in the pouring tube can continue to flow out from the liquid outlet; until the end plug is pressed on the annular convex edge; at this time, the piston is pressed against the inner wall of the second end of the pouring tube, and the end plug is pressed against the annular convex edge under the action of gravity and the pressure of the liquid inside the bottle, and the end plug and the annular convex edge form a sealing fit, and the liquid inside the bottle cannot continue to flow into the pouring tube, thereby preventing the continuous outflow of the liquid inside the bottle and preventing the liquid inside the bottle from being poured out all at once;

[0017] Since the amount of liquid poured out at one time is limited, if more liquid needs to be poured out, it can be poured several times. Before pouring the liquid each time, the bottle is first placed upright or nearly upright with the bottle mouth facing upward so that the end plug can move down and leave the annular convex edge, so that the inner cavity of the bottle is connected with the inner cavity of the pouring tube.

[0018] The advantages and beneficial effects of the present invention are: providing an automatic quantitative liquid discharging cap and a method for using the same; the automatic quantitative liquid discharging cap of the present invention is a bottle cap, which is installed on the bottle mouth of the bottle, so that the liquid in the bottle can be poured out without removing the bottle cap from the bottle mouth, and the liquid in the bottle can be prevented from being poured out all at once, and the amount of liquid poured out each time can be almost the same, so that quantitative liquid discharging can be basically achieved.

[0019] The piston has a built-in weight block. When pouring liquid (the liquid outlet of the pouring tube faces downward), the weight block can make the end plug and the piston move downward more smoothly, reduce the influence of the buoyancy of the liquid inside the bottle on the downward movement of the end plug, and make the piston move downward more quickly to fit against the inner wall of the second end of the pouring tube, thereby pouring the liquid more smoothly.

[0020] When the piston moves down quickly to abut against the inner wall of the second end of the pouring tube, the end plug is pressed against the annular convex edge and forms a sealing fit with the annular convex edge, so that the liquid inside the bottle cannot continue to flow into the pouring tube; therefore, each time the liquid is poured, the amount of liquid poured out is almost the same, and quantitative liquid discharge can basically be achieved.

[0028] The inside of the pouring tube 20 is also provided with a piston 31 which is slidably matched with the inner circumferential wall of the pouring tube 20, and the piston 31 is coaxial with the pouring tube 20; the piston 31 has a built-in weight block 32, the weight block 32 is annular or disc-shaped, and the weight block 32 is coaxial with the piston 31; the outer side of the first end of the pouring tube 20 is also provided with an end plug 35 which can be sealed with the annular convex edge 21, the end plug 35 is disc-shaped, and the end plug 35 is coaxial with the piston 31; the end plug 35 is connected to the outer side of the first end of the pouring tube 20. The connecting rod 33 is connected to the piston 31, and the connecting rod 33 and the piston 31 are coaxial; the connecting rod 33 is also provided with a support frame 34 that slides with the inner peripheral wall of the pouring tube 20, the support frame 34 is perpendicular to the connecting rod 33, and the support frame 34 is located between the piston 31 and the annular convex edge 21; the support frame 34 includes a plurality of support arms, the plurality of support arms are evenly distributed along the circumferential direction of the outer peripheral wall of the connecting rod 33, and the plurality of support arms are respectively arranged along the radial direction of the outer peripheral wall of the connecting rod 33;

[0029] The length of the connecting rod 33 is smaller than that of the pouring tube 20 , and is greater than the distance between the liquid outlet 22 and the annular ridge 21 ; the distance between the support frame 34 and the end plug 35 is smaller than the distance between the liquid outlet 22 and the annular ridge 21 .

[0030] The present invention also provides a method for using the above-mentioned automatic quantitative liquid discharging cover, comprising:

[0031] Take a bottle containing liquid, and install the main cover 10 on the bottle mouth of the bottle (the main cover 10 is threadedly connected with the bottle mouth);

[0032] When it is not necessary to pour out the liquid in the bottle, the bottle is placed upright, with the bottle mouth facing upward and the liquid outlet 22 of the pouring tube 20 facing upward; the piston 31, the weight block 32, the connecting rod 33, the support frame 34 and the end plug 35 move downward under the action of gravity until the support frame 34 is placed on the annular convex edge 21, as shown in FIG. Figure 3 As shown; at this time, the end plug 35 moves down to below the pouring tube 20, the inner cavity of the bottle is connected with the inner cavity of the pouring tube 20, and the piston 31 moves down to below the liquid outlet 22 of the pouring tube 20, and the piston 31 separates the liquid outlet 22 of the pouring tube 20 from the inner cavity of the bottle, so that the liquid inside the bottle is separated from the environment outside the liquid outlet 22 of the pouring tube 20;

[0033] When the liquid in the bottle needs to be poured out, the bottle is inverted, the bottle mouth is tilted downward, and the liquid outlet 22 of the pouring tube 20 is downward; the liquid in the bottle continues to flow into the pouring tube 20; the end plug 35, the connecting rod 33, the support frame 34, the piston 31 and the weight block 32 move downward under the action of gravity and the pressure of the liquid in the bottle; and when the piston 31 moves down to the liquid outlet 22 of the pouring tube 20, the liquid in the pouring tube 20 can continue to flow out from the liquid outlet 22; until the end plug 35 is pressed on the annular convex edge 21, as shown in FIG. Figure 4As shown; at this time, the piston 31 is pressed against the inner wall of the second end of the pouring tube 20, and the end plug 35 is pressed against the annular convex edge 21 under the action of gravity and the pressure of the liquid inside the bottle, and the end plug 35 and the annular convex edge 21 form a sealing fit, so that the liquid inside the bottle cannot continue to flow into the pouring tube 20, preventing the continuous outflow of the liquid inside the bottle and preventing the liquid inside the bottle from being poured out at once;

Before pouring the liquid each time, the bottle is first placed upright or nearly upright with the bottle mouth facing upward so that the end plug 35 moves downward and separates from the annular ridge 21, so that the inner cavity of the bottle is connected to the inner cavity of the pouring tube 20.

[0035] The piston 31 has a built-in weight block 32. When pouring liquid (the liquid outlet 22 of the pouring tube 20 faces downward), the weight block 32 can make the end plug 35 and the piston 31 move downward more smoothly, reducing the influence of the buoyancy of the liquid inside the bottle on the downward movement of the end plug 35, and making the piston 31 move downward more quickly to fit against the inner wall of the second end of the pouring tube 20, thereby pouring the liquid more smoothly.

[0036] When the piston 31 moves down quickly to abut against the inner wall of the second end of the pouring tube 20, the end plug 35 is pressed against the annular ridge 21 and forms a sealing fit with the annular ridge 21, so that the liquid inside the bottle cannot continue to flow into the pouring tube 20; therefore, each time the liquid is poured, the amount of the poured liquid is almost the same, and quantitative liquid discharge can basically be achieved.

[0037] As can be seen from the above, the present invention provides an automatic quantitative liquid discharging cap and a method of using the same. The automatic quantitative liquid discharging cap of the present invention is a bottle cap, which is installed on the bottle mouth of the bottle. The liquid inside the bottle can be poured out without removing the bottle cap from the bottle mouth, and the liquid inside the bottle can be prevented from being poured out all at once. The amount of liquid poured out each time is also almost the same, and quantitative liquid discharging can basically be achieved.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
