[0020] Such as Figure 1 And Figure 3As shown in the figure, a quantitative extrusion device 100 is used to quantitatively suck and extrude a preset liquid. The quantitative extrusion device 100 is characterized in that it includes a quantitative cylinder 110, a suction tube 120, a one-way inlet valve 130, a piston 140, a push rod 150, an extrusion head 160 and a one-way outlet valve 170. The quantitative cylinder 110 is made of a transparent material, and a scale 111 mark is provided on the side wall of the quantitative cylinder 110. The suction tube 120 is arranged at the bottom of the quantitative cylinder 110 and is communicated with the inside of the quantitative cylinder 110. One end of the suction tube 120 away from the quantitative cylinder 110 is used to extend into the preset liquid. The one-way inlet valve 130 is arranged at one end of the suction tube 120 close to the quantitative cylinder 110. The one-way inlet valve 130 is used to control the one-way entry of the preset liquid into the quantitative cylinder 110 through the suction tube 120. The piston 140 is arranged in the quantitative cylinder 110, and the piston 140 slides and seals relative to the quantitative cylinder 110. One end of the push rod 150 is connected to the piston 140, and the other end of the push rod 150 extends out of the top of the quantitative cylinder 110. The extrusion head 160 is arranged at the bottom of the side wall of the quantitative cylinder 110. An outlet channel 161 communicating with the quantitative cylinder 110 is opened inside the extrusion head 160. The one-way outlet valve 170 is arranged on the extrusion head 160. The one-way inlet valve 130 is used to control the one-way outflow of the preset liquid from the quantitative cylinder 110 through the outlet channel 161. In this embodiment, the preset liquid is an anti-aging essence. It can be understood that in other embodiments, the preset liquid can also be other skin care products that need to be quantitatively extruded. Specifically, the preset liquid can be a viscous liquid.

[0021] When skin care products such as anti-aging essence need to be used, the suction tube 120 of the quantitative extrusion device 100 is extended into skin care products such as anti-aging essence, and then when the push rod 150 is pulled upward, the piston 140 rises in the quantitative cylinder 110, and a negative pressure is formed in the quantitative cylinder 110. At this time, skin care products such as anti-aging essence flow into the quantitative cylinder 110 through the one-way inlet valve 130 under the action of atmospheric pressure. When the piston 140 rises to the required scale 111 position on the quantitative cylinder 110, stop pulling the push rod 150. At this time, the quantitative cylinder 110 accurately sucks the required amount of skin care products such as anti-aging essence. Then, the extrusion head 160 is aligned with the application part, and the push rod 150 is pushed downward. The piston 140 descends in the quantitative cylinder 110, pushing the essence in the quantitative cylinder 110. Under the thrust of the piston 140, the essence is extruded from the extrusion head 160 through the outlet channel 161 and the one-way outlet valve 170 to the application part. Through the quantitative extrusion device 100 of the present application, the quantitative extrusion of skin care products such as anti-aging essence can be realized for quantitative sucking and extrusion, so that skin care products such as anti-aging essence are used according to the best usage amount, which will neither cause waste nor need to be squeezed and extracted multiple times.

[0022] In this embodiment, the measuring cylinder 110 is made of medical-grade transparent plastic material. The cost of the plastic is relatively low, and the transparency facilitates observing whether the skin care products such as anti-aging essence liquid in the measuring cylinder 110 reach the required amount. The medical grade better guarantees the safety of users. Specifically, the measuring cylinder 110 is made of medical-grade polycarbonate material, such as polycarbonate (PC); the measuring cylinder can be manufactured by injection molding; wherein, the scale accuracy marked by the scale 111 is 0.1 ml. It can be understood that in other embodiments, the scale accuracy marked by the scale 111 can also be larger or smaller, such as the scale accuracy is 0.05 ml, 0.2 ml, 0.25 ml, 0.3 ml, 0.5 ml, etc.

[0023] In this embodiment, the suction tube 120 is made of plastic material. It can be understood that the suction tube 120 can also be made of the material of the suction tube in the relevant quantitative extrusion device in the prior art, as long as the function can be realized.

[0024] In one embodiment, the push rod 150 is fixedly connected to the piston 140, such as by welding, bonding, integral molding and other methods to realize the fixed connection between the push rod 150 and the piston 140.

[0025] In another embodiment, the push rod 150 is detachably connected to the piston 140. Thus, when the push rod 150 is damaged such as broken, only the push rod 150 needs to be replaced, and there is no need to replace the entire quantitative extrusion device 100, and the replacement cost is lower. For example, the detachable connection between the push rod 150 and the piston 140 is realized by snap connection, threaded connection and other methods.

[0026] In this embodiment, the piston 140 is in interference fit with the measuring cylinder 110. Specifically, the diameter of the piston 140 is slightly larger than the inner diameter of the measuring cylinder 110. In this embodiment, the diameter of the piston 140 is 0.2 - 0.3 millimeters larger than the inner diameter of the measuring cylinder 110.

[0027] Furthermore, the piston 140 is made of silicone material. Silicone has good elasticity and sealing performance, and can better realize the sealed sliding connection between the piston 140 and the push rod 150. It can be understood that the piston 140 can also be made of other materials with good elasticity and sealing performance, such as rubber, etc. Reference Figure 1 , anti-slip lines 151 are provided on the outer surface of the push rod 150. Through the setting of the anti-slip lines 151, the probability of the user slipping when operating the push rod 150 can be reduced, so as to more reliably realize operations such as pushing and pulling the push rod 150.

[0028] Reference Figure 1 , a handle 1030 is provided at the top of the push rod 150. Specifically, through the setting of the handle 1030, the user can directly hold the handle 1030 to operate the push rod 150, and the operation is reliable and convenient.

[0029] In this embodiment, both the one-way inlet valve 130 and the one-way outlet valve 170 can be duckbill valve one-way valves made of rubber material, and their opening pressure is 0.05 - 0.1 MPa, ensuring that the essence can flow smoothly into the measuring cylinder 110 and will not flow back. It can be understood that in other embodiments, the one-way inlet valve 130 and the one-way outlet valve 170 can also adopt other one-way valves, as long as they can achieve the one-way flow of skin care products such as anti-aging essence.

[0030] Reference Figure 1 , the quantitative extrusion device 100 further includes a first control valve 180, and the first control valve 180 is arranged on the extrusion head 160. The first control valve 180 is used to control the on-off of the liquid outlet channel 161. Specifically, through the setting of the first control valve 180, it can further prevent the preset liquid, that is, skin care products such as anti-aging essence, from leaking out of the measuring cylinder 110. In addition, it can also prevent external dirt, sundries, dust, etc. from entering the measuring cylinder 110 through the liquid outlet channel 161. During normal times, the first control valve 180 controls the liquid outlet channel 161 to be blocked. When it is necessary to extrude skin care products such as anti-aging essence and the measuring cylinder 110 has drawn the required amount of skin care products such as anti-aging essence, the first control valve 180 controls the liquid outlet channel 161 to be conducted. After the skin care products such as anti-aging essence are quantitatively extruded to the application site, the first control valve 180 controls the liquid outlet channel 161 to be blocked again.

[0031] Optionally, the first control valve 180 is a manual ball valve or a solenoid valve.

[0032] Reference Figure 1 , the quantitative extrusion device 100 further includes a sealing cover 190, and the sealing cover 190 is threadedly and sealedly connected to the extrusion head 160. Specifically, the setting of the sealing cover 190 can further prevent external dirt, sundries, dust, etc. from entering the measuring cylinder 110 through the liquid outlet channel 161. Among them, the sealing cover 190 has an internal thread, and the extrusion head 160 has an external thread. The sealing cover 190 and the extrusion head 160 are threadedly and sealedly connected through the cooperation of the internal thread and the external thread.

[0033] Reference Figure 1 and Figure 3 , the quantitative extrusion device 100 further includes a return spring 1010. One end of the return spring 1010 is connected to the piston 140, and one end of the return spring 1010 is connected to the top of the measuring cylinder 110. Specifically, after pushing the push rod 150 downward to extrude skin care products such as anti-aging essence from the extrusion head 160 to the application site through the liquid outlet channel 161 and the one-way outlet valve 170, the piston 140 can automatically reset under the action of the return spring 1010. That is, when the user uses the quantitative extrusion device 100 of the present application, only by pushing the push rod 150 can the quantitative extrusion of skin care products such as anti-aging essence be completed, and the operation is simple and convenient.

[0034] Reference Figure 3 In addition, the metering and extrusion device 100 further includes a stop plate 1020 disposed within the metering cylinder 110 between the piston 140 and the top of the metering cylinder 110. The stop plate 1020 is used to stop the movement of the piston 140 towards the top of the metering cylinder 110 and is axially movable along the metering cylinder 110. Specifically, the stop plate 1020 enables the piston 140 to automatically return to the required position under the action of the return spring 1010. Since the position of the stop plate 1020 is adjustable, the user can adjust the metered extrusion amount according to needs. For example, when the stop plate 1020 is moved to the 10 ml position, the piston 140 can automatically return to the 10 ml position each time under the action of the return spring 1010, thereby metering the suction and extrusion of 10 ml of skin care products such as anti-aging essence.

[0035] Specifically, the stop plate 1020 is an annular plate; in other embodiments, the stop plate 1020 may also be a stop block disposed on the inner sidewall of the metering cylinder 110, and the number of the stop plates 1020 may be two or more, so as to more reliably stop the piston 140. For example, the stop block includes four or eight uniformly arranged stop blocks. It can be understood that as long as the stop plate 1020 can stop the piston 140, the stop plate 1020 can have various shapes or numbers.

[0036] Furthermore, in one embodiment, the metering and extrusion device 100 further includes a locking member (not shown in the figure), and the locking member is used to lock the stop plate 1020 relative to the metering cylinder 110 and lock the stop plate 1020 at the required position.

[0037] Such as Figure 1 、 Figure 2 and Figure 3 As shown, a container includes a receiving body 200, a cover body 300, and the above-mentioned metering and extrusion device 100. The receiving body 200 is used to receive a preset liquid, the cover body 300 is a sealing cover 190 disposed on the receiving body 200, the metering and extrusion device 100 is disposed on the cover body 300, and the suction tube 120 passes through the cover body 300 and extends into the bottom of the receiving body 200.

[0038] In this embodiment, the receiving body 200 is a bottle body, and the cover body 300 is a bottle cap. Since the metering and extrusion device 100 is disposed on the cover body 300, the assembly process is omitted, and only by operating the push rod 150 can the required amount of skin care products such as anti-aging essence be metered and extracted. Furthermore, when there is a return spring 1010, the user only needs to push (i.e., press) the push rod 150 each time to complete a metered extrusion, because when the return spring 1010 drives the piston 140 to return, the metered suction process will be completed.

[0039] In this embodiment, the bottle body is made of a transparent or semi-transparent high-strength plastic material. It can be understood that in other embodiments, the bottle body can also be made of an opaque material.

[0040] Reference Figure 3 , the container further includes a sealing ring 400, and the sealing ring 400 is arranged at the contact part between the cover body 300 and the accommodating body 200. Specifically, the accommodating body 200, that is, the bottle body, has an opening (bottle mouth), and the sealing ring 400 is arranged at the contact part between the cover body 300 and the opening of the accommodating body 200.

[0041] Further, with reference to Figure 2 and Figure 3 , an external thread 210 is provided at the open end of the accommodating body 200, and an internal thread 310 matching the external thread 210 of the accommodating body 200 is provided inside the cover body 300. The cover body 300 is threadedly connected to the accommodating body 200.

[0042] Reference Figure 2 , the container further includes an antioxidant component 500. The antioxidant component 500 includes an inert gas storage member 510, a connecting pipe 520, and a second control valve 530. The inert gas storage member 510 is connected to the accommodating body 200. The inert gas storage member 510 is in internal communication with the accommodating body 200 through the connecting pipe 520. The second control valve 530 is arranged on the connecting pipe 520, and the second control valve 530 is used to control the on-off of the connecting pipe 520. Specifically, when skin care products such as anti-aging essence liquid in the accommodating body 200 are used for a period of time, in order to prevent the oxidation of skin care products such as anti-aging essence liquid, the control valve on the connecting pipe 520 can be opened to supplement inert gas into the accommodating body 200, discharge the air above in the accommodating body 200, and maintain an oxygen-free environment in the accommodating body 200.

[0043] In this embodiment, the inert gas storage member 510 is installed at the bottom or side of the bottle body and is in internal communication with the bottle body through the connecting pipe 520. A control valve is provided on the connecting pipe 520; the inert gas storage member 510 is a nitrogen storage tank.

[0044] Further, the connecting pipe 520 is a high-pressure resistant plastic hose with an inner diameter of 2-3 mm; the nitrogen storage tank is made of aluminum alloy, with a capacity of 50-100 ml and a working pressure of 1-2 MPa.

[0045] Optionally, the second control valve 530 is a manual ball valve or a solenoid valve.
