As shown in fig. 1 and 2, the screw pressurizing capacity cover according to the embodiment of the first aspect of the present utility model includes a housing 100 and a rotating body 200, the housing 100 including two cylinders having different sizes, and the two cylinders being integrally injection-molded. The cylinder with larger diameter is a second chamber 120, the cylinder with smaller diameter is a first chamber 110, one end of the first chamber 110 extends into the second chamber 120 and is connected with the second chamber 120, so that the first chamber 110 is communicated with the second chamber 120, and at this time, the second chamber 120 is provided with an internal thread 121 on an inner wall corresponding to the first chamber 110. In this embodiment, the length of the first chamber 110 is greater than that of the second chamber 120, but the present utility model is not limited to the length of the first chamber 110, and the first chamber 110 is sequentially divided into a feeding section 111 and a sealing section 112 from a direction away from the second chamber 120 to a direction close to the second chamber 120, wherein the length of the feeding section 111 is greater than that of the sealing section 112, the first chamber 110 is provided with a plurality of feeding holes 1111 in the feeding section 111 to meet the feeding requirement, and the first chamber 110 is not provided with any hole in the sealing section 112 to meet the sealing requirement of the sealing section 112.

As shown in fig. 2 and 3, the rotating body 200 includes an extension rod 210 and an outlet chamber 220 connected to each other, and since the rotating body 200 is movable inside the housing 100, the outlet chamber 220 has a smaller diameter than the second chamber 120 but larger than the first chamber 110, and the extension rod 210 has a smaller diameter than the first chamber 110, so that the outlet chamber 220 can be movable in the second chamber 120 and the extension rod 210 can be movable in the first chamber 110.

In order to achieve the movable connection between the rotary body 200 and the housing 100, the second chamber 120 is provided with a spiral guide groove 122, and the discharging chamber 220 is provided with a guide post 221 slidably connected to the spiral guide groove 122, where the axis of the discharging chamber coincides with the axis of the second chamber. When the rotating body 200 rotates relative to the housing 100, the rotating body 200 can also move along the axial direction of the second chamber 120 while rotating under the guiding action of the spiral guide groove 122, so as to realize the spiral connection of the rotating body 200 and the housing 100.

It is understood that the number of the spiral guide grooves 122 may be one, two, three, etc., and correspondingly, the number of the guide posts 221 is identical to the number of the spiral guide grooves 122, and when the number of the spiral guide grooves 122 is set to be greater, the spiral movement between the rotating body 200 and the housing 100 is also more stable, but in consideration of the production cost, both the number of the spiral guide grooves 122 and the number of the guide posts 221 may be selected to be two in the present embodiment.

In addition, the extension rod 210 is fixedly connected to one end of the discharging chamber 220, the extension rod 210 extends into the first chamber 110, the spiral blade 211, the first spacer 212 and the second spacer 213 are sequentially disposed on the outer circumferential surface of the extension rod 210 from the direction away from the discharging chamber 220 to the direction close to the discharging chamber 220, the first spacer 212 and the second spacer 213 can be sealed to the sealing section 112, that is, the diameters of the first spacer 212 and the second spacer 213 are not smaller than the diameter of the sealing section 112, or the outer walls of the first spacer 212 and the second spacer 213 are sleeved with sealing rings, under the combined action of the first spacer 212, the second spacer 213 and the sealing section 112, the content between the first spacer 212 and the second spacer 213 can be effectively sealed, a quantitative area 201 is formed between the first spacer 212 and the second spacer 213, and the volume of the quantitative area 201 is positively correlated with the distance between the two spacers and the difference between the diameters of the extension rod and the first chamber. Since the discharge chamber 220 can perform a spiral movement with respect to the second chamber 120, the extension rod 210 can also perform a spiral movement with respect to the first chamber 110, and in order to meet the requirement of quantitative discharge, the moving path of the quantitative region 201 needs to pass through the second chamber 120 and at least one of the feeding holes 1111, but the quantitative region 201 is not simultaneously connected to the feeding holes 1111 and the second chamber 120.

In order to guide the content in the quantitative region 201 into the discharge chamber 220, the discharge chamber 220 is provided with a guide hole 222 and a discharge hole 223 which are mutually communicated, the guide hole 222 is communicated with the first chamber 110, and the guide hole 222 is spaced from the second spacer 213 so as to prevent the second spacer 213 from blocking the guide hole 222. When the dosing region 201 is in communication with the second chamber 120 following the movement of the rotating body, the content in the dosing region 201 can flow out to the second chamber 120 first, and enter the discharge chamber 220 through the flow guiding hole 222, and finally the content in the discharge chamber 220 flows out to the outside through the discharge hole 223. Since the quantitative region 201 has a fixed volume, the quantitative discharging can be achieved if the contents can flow out to the outside through the second chamber 120, the flow guiding hole 222, the discharging chamber 220, and the discharging hole 223 in sequence.

Further, in order to guide the entire content in the quantitative region 201 to the discharge chamber 220 so as not to leak the content to the outside through the second chamber 120, the outer wall of the discharge chamber 220 is kept sealed from the inner wall of the second chamber 120, thereby retaining the content between the discharge chamber 220 and the second chamber 120. Specifically, the outer wall of the discharging chamber 220 is provided with a sealing portion 224, the sealing portion 224 may be a sealing ring or a sealing ring, and the diameter of the sealing portion 224 is not smaller than the diameter of the inner wall of the second chamber 120. And, the guide post 221 of the discharging chamber 220 is located at a side of the sealing portion 224 away from the extension rod 210, so as to prevent the content from flowing out of the spiral guiding groove 122 to the outside.

As shown in fig. 6, with the above arrangement, the screw pressurizing dosing cap is used to be mounted at the bottom of the bottle body 400, at this time the first chamber 110 is extended into the bottle body 400, when the rotating body 200 is operated to be in the closed position, the dosing region 201 is communicated with at least one of the feed holes 1111, but the dosing region 201 is not communicated with the second chamber 120, the content in the bottle body 400 is entered into the dosing region 201 through the feed hole 1111 for quantitative storage, when the rotating body 200 is operated to be in the open position, the dosing region 201 passes over the first chamber 110 and is communicated with the second chamber 120, but the dosing region 201 is not communicated with the feed hole 1111, so that the content in the dosing region 201 can flow to the second chamber 120 and enter into the discharge chamber 220 through the guide hole 222, and finally flows out from the discharge hole 223 to the outside, so that quantitative discharge is achieved. After the use, the rotary body 200 is re-executed to be in the closed position, at which time the dosing region 201 is in communication with at least one of the feeding holes 1111, while the dosing region 201 is not in communication with the second chamber 120, and the content in the bottle body 400 is refilled in the dosing region 201 for the next dosing operation. Compared with the prior art, the quantitative discharging device can easily quantitatively discharge the content in the bottle body 400, is simple in structure, is not easy to fail, and has good market prospect.

The spiral blade 211 is configured to spiral and push the content to the quantitative region 201 during the process of switching the rotating body 200 from the closed position to the open position, so as to increase the internal pressure of the quantitative region 201, and make the discharging faster and smoother.

It will be appreciated that the amount of each discharge of the screw-on pressurized dosing cap is dependent on the volume of the dosing region 201, whereas the volume of the dosing region 201 is positively correlated with the distance between the two spacers and the diameter difference between the extension rod and the first chamber. Generally, the difference in diameter between the extension rod and the first chamber is constant, so in order to adjust the volume of the quantitative region 201, the first spacer 212 and/or the second spacer 213 is adjustably coupled to the outer circumferential surface of the extension rod 210 to adjust the volume of the quantitative region 201 by adjusting the distance between the first spacer 212 and the second spacer 213.

Specifically, the outer circumferential surface of the extension rod 210 is provided with a plurality of positioning grooves (not shown in the drawings) at intervals in the axial direction, the positioning grooves are used for assembling spacers, and the first spacer 212 and the second spacer 213 can be assembled in different positioning grooves, respectively, as required, to adjust the relative position between the first spacer 212 and the second spacer 213, thereby adjusting the volume of the dosing region 201.

In some embodiments of the present utility model, as shown in fig. 1, in order to avoid the content in the discharge chamber 220 from flowing out to the second chamber 120, the discharge hole 223 extends outwards to form a discharge hole 225, and the discharge hole 225 should be kept outside the second chamber 120, but the present utility model is not limited to a specific position of the discharge hole 225, and only needs to be outside the second chamber 120 when the rotating body 200 is in the open position. Correspondingly, the shell 100 is provided with a shielding part 123 for blocking the discharge hole 225 on the moving path of the discharge hole 225, so that when the rotator 200 is in a closing station, the shielding part 123 can block the discharge hole 225 to prevent the leakage of the content in a non-use period; when the rotary body 200 is in the open position, the discharge port 225 can be separated from the shielding portion 123, so as to realize smooth outflow of the content.

In some embodiments of the present utility model, in order to facilitate the user to rotate the rotator 200, the discharging chamber 220 is provided with a rotation position 300 at a position away from the extension rod 210, and the rotation position 300 should remain externally located to the second chamber 120, but the present utility model is not limited to the specific position of the rotation position 300. The rotation position 300 may be in different structures such as a tooth socket, a handle, a knob, etc., as long as it is convenient for a user to rotate the rotation body 200, and no matter what structure the rotation position 300 is, it is within the protection scope of the present utility model.

As shown in fig. 4 to 6, the liquid container according to the second aspect of the present utility model includes the screw pressurizing quantitative cap according to the above first aspect of the present utility model, and further includes a bottle body 400, wherein an external screw thread opening 410 is provided at the bottom of the bottle body 400, and the second chamber 120 is provided with an internal screw thread 121 matching the external screw thread opening 410 on the inner wall corresponding to the first chamber 110, so as to satisfy the screw connection of the screw pressurizing quantitative cap with the bottle body 400. When the screw pressurizing quantitative cap is mounted on the bottle body 400, the first chamber 110 is extended into the bottle body 400 in a homeopathic manner, and the second chamber 120 is externally disposed on the bottle body 400 and exposes the rotation position 300 of the rotation body 200.
