Xiang Qin Zai_ Fill in | Ill IIIIII Order the result of this combination 'When the capsule is compressed without liquid, although the valve will be closed because the air in the capsule is compressed', but the air to be discharged inside At this time, the check valve opens and exhausts air. When the compressive force experienced by the capsule disappears, the capsule returns to the extended direction, and a negative pressure is generated in the capsule. As soon as the inspection valve is closed, the valve opens and the liquid is discharged from the container body into the capsule, thereby filling the capsule. Then, when the capsule is compressed again, the valve prevents the liquid in the capsule from moving into the container body, so the liquid in the capsule opens and discharges the inspection valve. The discharged liquid is discharged from the container body through the discharge pipe without returning the liquid through the inspection valve. Here, when the liquid in the container body is discharged from the container body, the flow velocity of the liquid is increased because of the partition section of the inspection valve, so the liquid is quickly discharged from the drain pipe. In addition, it is possible to prevent the liquid from overflowing when the container body falls by the partition section. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Therefore, according to the present invention, since the liquid in the container body can be discharged by expansion and contraction of the capsule, wherein the container body serves as a liquid-accommodating element that is not required in the case of using a spring, This can reduce the number of parts and assembly steps. Because each component can be molded from plastic, it can be reassembled or recycled more easily than with a steel coil spring, valve or inspection valve.

When the liquid pressure exceeds the elasticity of the above-mentioned sections S1 and S2, the above-mentioned two sections S1 and S2 will be elastically deformed, as shown in Fig. 12, so that the liquid can be discharged at one time. As a result, the liquid can be quickly discharged for the first time. In addition, even if the valve B and the inspection valve G are opened when the container engaging the valve member VU is down, the slit plate 39 prevents the liquid from overflowing to the outside. In addition, when the container does not fall, even if the liquid in the capsule 28 is to be discharged due to the increase in the pressure in the capsule 28, the slit plate 39 can prevent this from happening, so it can also be avoided when the container does not fall. The liquid drips from the discharge end 43. Therefore, according to a specific embodiment of the present invention, it provides the advantage that it is easy to use but the liquid does not drip out from the discharge end 43 of the terminal 42 of the discharge pipe 21. In addition, because the elasticity of the two sections S1 and S2 divided by the slit S can be adjusted by using the thickness of the thin area 40 of the slit plate 39 and the length of the slit S, the degree of freedom in considering the design of the container falling down is very high. high. Here, when the slit plate 39 is integrated with the capsule 28 and the inspection valve G, the number of parts and assembly steps can be reduced, thereby reducing costs. Because the capsule 28, the inspection valve G, the valve B, and the intake pipe 27 can be integrally formed by blow molding, the cost can be significantly reduced. Further, since the valve body 33 inserted therein can be molded from plastic, it can be easily recycled together with the container body Y and other parts, thereby making the present invention environmentally friendly. Here, FIG. 3 shows the storage state of the container. In this storage state, since the female threaded section 26 of the pressure section 25 of the piston section P engages with the locking threaded section 24 of the guide element I5, as described above, 19 copies of the piston section P Paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ----------- installation --------- order --------- line (Please read the note on the back?
