Next, the cylinders 133a and 133b according to one embodiment of the present invention have a double cylinder shape, and may be provided with various materials including synthetic resins and are integrally molded double cylinders, as shown in the drawings, respectively, on the same axis line. It is formed into a gas cylinder 133a having a large outer diameter and a liquid cylinder 133b having a small outer diameter.

The pistons 110a and 110b are composed of a gas piston 110a made of a synthetic resin having a large outer diameter and a liquid piston 110b made of a synthetic resin having a small outer diameter, which are provided on the same axis, and the gas piston 110a and a liquid piston. When inserting 110b into the gas cylinder 133a and the liquid cylinder 133b, respectively, the pistons 110a and 110b are always in an upward direction via a spring 191 between at least one cylinder and the piston. Allow elastic pressurization. In the embodiment, the spring 191 is mounted between the liquid cylinder 133b and the liquid piston 110b.

The double cylinders 133a and 133b will be described in detail again. The gas cylinder 133a is compressed by the container 10 and the screw on the upper side, and has a wing portion 131a for maintaining airtightness, and a guide tube portion having an outer diameter smaller than the wing portion 131a downward from the wing portion 131a. It consists of a cylinder part consisting of the gas sliding cylinder part 131b of uniform inner diameter of a small outer diameter continuously, and the bottom part which extends radially inward from the lower end of the gas sliding cylinder part 131b, and inverts a center part upwards. .

The third check valve 173 extends outward from the third check valve body 173a toward the inner diameter side of the gas piston 110a to open and close the intake holes 181 formed through the same circumference. The outer valve member 173b and the third check valve body 173a to extend toward the central axis of the gas piston 110a so as to be supported by the annular protrusion 117 so as to open and close the gas passage 0. The provided inner valve member 173c is provided. Here, the outer valve member 173b and the inner valve member 173c are easily adhered to the horizontal plate member 117b or the annular projection 117 which are easily deformed and deformed by pressurization of the gas, and thus the adhesiveness can be kept airtight. A material such as a soft synthetic resin having a property that can be easily deformed or a rubber capable of maintaining such a function is preferable.

In the 3rd check valve main body 173a, the upward protrusion shape is supported by the 3rd check valve support part 117a formed in the horizontal board member 117b of the gas piston 110a.

A gas passage O is formed at an interval portion between the upper outer surface of the liquid piston 110b press-fitted into the upper rod 117c and the inner surface of the upper rod 117c so that the gas in the gas chamber 140a is mixed with the mixing chamber 140c. Can be moved to).

The third check valve 173 typically has an outer edge of the outer valve member 173b in contact with an inner surface of the upper wall, and an inner edge of the inner valve member 173c is connected to the annular projection 117 of the liquid piston 110b. While in contact with the gas chamber 140a, if the pressure in the gas chamber 140a increases, the inlet of the gas passage O, that is, the communication passage between the gas chamber 140a and the gas passage O, as shown in FIGS. 3A and 3B is closed. As the inner valve member 173c of the third check valve body 173a is displaced upward (elastic displacement) and is separated from the annular protrusion 117, the inlet of the gas passage O is opened and the gas chamber ( When the inside becomes negative pressure 140a, as illustrated in FIG. 1, the outer valve member 173b of the third check valve body 173a closing the suction hole 181 is displaced downward. Elastic displacement) to the plate surface inside the horizontal plate member 117b in the outward direction of the suction hole 181. Off to open the suction hole (181).

The upper rod 117c of the hollow gas piston 110a in the gas piston 110a is composed of a lower portion into which the liquid piston 110b is press-fitted and a portion forming a mixing chamber 140c thereon, Since the lower portion forms a gas passage O between the outer surface of the liquid piston 110b, the inner diameter of the virtual circle connecting the inner surface of the longitudinal rib 188 is approximately the outer diameter of the liquid piston 110b. The upper portion is divided into equal parts and the inner diameter is reduced smaller than the outer diameter of the liquid piston 110b. In the mixing chamber 140c, a plurality of longitudinal ribs 188 are provided radially, and a mixed liquid discharge port 187 is provided at an upper end thereof.

In addition, the piston ring member (115a, 115b) can be selected in various ways in consideration of the degree of airtightness of the contents, storage period, the number of times of use. In addition, the lip portions 115a3 and 115b3 at both ends of the piston ring members 115a and 115b can always be in close contact with the inside of the gas cylinder 133a and the liquid cylinder 133b, thereby improving airtightness. In addition, the piston ring members 115a and 115b have a structure that can be attached to and detached from the piston bodies 111a and 11b, and can be selected as appropriate shapes, materials, and the like according to the contents.

The whole liquid piston 110b has a substantially cylindrical shape, and a second valve seat 172b having a shape in which the outer diameter increases as the inner diameter increases in the upward direction is provided on the inner surface side of the upper end portion. On the other hand, the lower end part is provided with the liquid piston ring member 115b which moves up and down in the state in which the liquid inside the liquid cylinder 133b kept airtight.

In the liquid piston 110b, a rod-shaped second check valve 172 and a cylindrical stopper 185 are mounted to the liquid piston 110b to move up / down the pistons 110a and 110b. According to the opening and closing of the liquid outlet of the upper end of the liquid piston (110b).

The second check valve 172 is provided at the upper end of the long rod-shaped second valve body 172a and the second valve body 172a in a shape of increasing the outer diameter of the upper side and reducing the outer diameter of the lower side. A second valve sealing portion 172c is engaged with the second valve seat 172b of the liquid piston 110b to open and close the liquid outlet port so that the liquid in the liquid chamber 140b can enter and exit the mixing chamber 140c. In addition, the second check valve 172 is accommodated in the stopper 185 to guide the vertical movement of the second check valve 172 in the process of moving up and down and the stopper 185 to limit the moving distance of the stopper 185. The protrusion is formed in the lower end part above ().

On the other hand, the cylindrical stopper 185 has an annular unillustrated receiving portion facing outward that becomes a lower receiving portion of the spring 191 at the lower end thereof, and a longitudinally unshown opening having its upper side as a liquid passage. A cylindrical shape is provided with a plurality of grooves (or divided grooves) radially, and the lower end portion is supported below the liquid cylinder 133b. Moreover, the area | region in which the processus | protrusion of the lower end side of the 2nd check valve 172 was formed is accommodated inside the upper end of the stopper 185. As shown in FIG.

Therefore, when the user presses the nozzle unit 160 and the nozzle unit 160 descends with respect to the cap member 150, the first check ball 171a pushes the liquid inlet area to seal the liquid chamber 140b. Of the liquid may be discharged to the mixing chamber 140c, and the first check ball 171a is liquid when the nozzle unit 160 rises with respect to the cap member 150 by releasing the pressing force of the nozzle unit 160. The lower end protrusion of the second check valve 172 moves the stopper 185 upward so as to open the suction part, and the first check ball 171a moves upward to open the hole into which the liquid is sucked. Can be. That is, the cylindrical stopper 185 is supported under the liquid cylinder 133b and disposed inside the liquid cylinder 133b or the liquid chamber 140b, so that the first check ball 171a of the first check valve 171 can be disposed. The climb distance is limited to its lower end.

A plurality of mesh members 169 may be coupled to an upper portion of the upper rod 117c of the gas piston 110a so that bubbles generated in the mixing chamber 140c may be finely and homogenized while passing through the mesh members 169.

In addition, according to one embodiment of the present invention, the state in which the nozzle unit 160 is inoperable and the state in which the nozzle unit 160 is operated by engaging the container 10 by using the cap member 150. Locking means (167a, 67b) capable of rotational movement. In the present embodiment, there is one locking protrusion 167a that can be locked to the nozzle receiving portion 153 of the cap member 150, unlike FIG. 4A, which will be described later. In the process of releasing, the locking projection guide formed in the cap member 150 for guiding the vertical movement of the locking projection 167 is one.

The operation of the forming pump device 100 according to an embodiment of the present invention having such a configuration will be described in detail with reference to FIGS. 1 to 3B.

As shown in FIG. 1, when the container 10 is placed in the forming pump apparatus 100, the gas hole 33 is closed by the gas piston ring member 115a of the gas piston 110a and the liquid piston 110b. The second valve sealing portion 172c and the rod-shaped second valve seat 172b on the upper side of the () are coupled to each other to close the liquid passage. This closed state can be maintained continuously by the locking means described later. That is, the forming pump apparatus 100 may be accommodated in the container 10 in which the contents are accommodated, and thus may remain locked in the state of FIG. 1 in a process of packaging, transporting, storing, and displaying the store. If necessary, of course, the locking state of the forming pump apparatus 100 may be maintained in the state of FIG. 3B.

In the state shown in FIG. 1, the forming pump device 100 is assembled to the container 10 and maintained until just before the consumer starts using it. Since the gas hole 187 is closed as described above even in the case of being subjected to a force or being kept inclined for a long time, the invasion of the foamable liquid A into the gas cylinder 133a is prevented. In addition, even when the container 10 is in the inverted state, the first check valve 171 is opened to allow the foaming liquid A to enter the liquid chamber 140b or to rapidly increase the pressure inside the container 10 as the temperature increases rapidly. The liquid passage is closed even when the foamable liquid A filling the inside of the liquid absorbing tube 183 enters the liquid chamber 140b by pressing the first check ball 171a of the first check valve 171 upward. Since the foamable liquid A does not leak out of the container 10 via the mixing chamber 140c at the outlet side of the liquid passage, or does not flow back into the gas chamber 140a.

In the case of using the forming pump apparatus 100 according to the present invention, the nozzle unit 160 is slidable in the vertical direction by releasing various kinds of known locking devices that restrict the movement of the nozzle unit 160 in the vertical direction. do. Then, it will be in the state as shown in FIG. In this state, one end of the coil spring 191 is coupled to a locking jaw (not shown) formed at the end of the stopper 185 at the other end of the spring 191 inside the liquid piston 110b to support the stopper 185. The liquid piston 110b is elastically pressurized with respect to the lower side of the liquid cylinder 133b. Accordingly, the protrusion of the lower end of the second check valve 172 coupled to the liquid piston 110b may be caught by the stopper 185 to seal the outlet of the upper portion of the liquid piston 110b.

In the following description, the nozzle unit 160 descends to the middle as shown in FIG. 3A at the maximum rising position of FIG. 1, and the nozzle unit 160 descends to the maximum from FIG. 3A to FIG. 3B. The operation of the forming pump device 100 will be described in more detail.

Next, when the pressing main body 165 of the nozzle unit 160 is pressed against the elasticity of the spring 191 by hand, the gas piston 110a and the gas piston 110a that are pressed into the upper portion of the nozzle unit 160 are pressed. The liquid piston 110b inserted in the upper portion of the lowers simultaneously.

In this process, the rod-shaped second check valve 172 does not lower until it collides with the bottom of the longitudinal rib 188 in the mixing chamber 140c above the upper rod 117c of the gas piston 110a. It is pushed down by the directional rib 188 to descend. Accordingly, in the second check valve 172, the second valve seat 172b and the second valve sealing part 172c of the rod-shaped second check valve 172 are in close contact with each other and the upper end of the liquid piston 110b is shown in FIG. 1. Although the liquid outlet is closed, when the gas piston 110a and the liquid piston 110b start to descend, the second valve seat 172b and the second valve sealing portion 172c are spaced apart from each other as shown in FIG. 3A. In this state, the liquid discharge port from the liquid chamber 140b to the mixing chamber 140c may be opened to move the liquid from the liquid chamber 140b to the mixing chamber 140c (see dotted line in FIG. 3A).

When the gas piston 110a and the liquid piston 110b are lowered together, the first check valve 171 is the first check valve seat 171b by the foamed liquid A in which the first check ball 171a is pressurized. The lower end of the liquid cylinder 133b on the side of the liquid absorbing tube 183, which is the inlet of the liquid chamber 140b, is kept closed because of the force pressed toward the side of the liquid chamber 140b. On the other hand, since the third check valve 173 receives the pressing force from the gas from which the third check valve body 173a is pressurized to the inner side of the horizontal plate member 117b, the outer valve member 173b is formed of the horizontal plate member 117b. It is in close contact with the inner surface to block the intake hole 181. On the other hand, the inner valve member 173c faces upward by the pressure of the gas chamber 140a and the gas pressurized from the gas chamber 140a as a result of the inner edge spaced apart from the upper surface of the annular protrusion 117 of the liquid piston 110b. It moves to the mixing chamber 140c via the gas passage O through the spaced space of the open inner valve member 173c.

As the gas piston 110a and the liquid piston 110b descend, the gas chamber 140a and the liquid chamber 140b are compressed, and the gas in the gas chamber 140a and the expandable liquid in the liquid chamber 140b are pressurized, respectively. The gas is formed in the transverse direction of the inner surface of the upper rod 117c and the longitudinal groove portion of the gas cylinder 133a and the outer surface of the liquid piston 110b and the inner surface of the shaft diameter portion of the upper rod 117c of the gas piston 110a. It enters into the mixing chamber 140c through the gas passage O formed between the part and the upper end of the liquid piston 110b, and the effervescent liquid enters the mixing chamber 140c at the outlet through the liquid passage in the liquid piston 110b. ) And where both are mixed to form a bubble.

In this process, the piston ring members 115a and 115b according to the present invention are rotatably coupled to the piston bodies 111a and 111b to allow sliding movement while maintaining effective and airtightness with the sliding cylinder portions 133a and 133b. In addition, since the airtightness can be stably maintained even when stopped for a long time, there is no fear that liquid or the like is discharged to the discharge port 163, and the appearance can be kept beautiful.

The foam then exits the mixing chamber 140c and passes through the mesh member 169 disposed in the foam passage through the mixed liquid discharge port 187 to change into a soft and finely homogenized foam, and then discharge channel of the nozzle unit 160. It is discharged to the outside of the forming pump device 100 through the outlet 163 of the tip via 161.

In this process, bubbles may be discharged through the discharge port 163 until the nozzle unit 160 reaches the maximum lowered state as shown in FIG. 3B.

When the nozzle unit 160 is lowered as far as possible and the force for pressing the nozzle unit 160 is released, the liquid piston 110b and the gas piston 110a and the nozzle which are integrated with the liquid piston 110b by the elasticity of the spring 191 are released. The portion 160 immediately starts the ascension and the rod-shaped second check because the second valve sealing portion 172c of the raised liquid piston 110b contacts the second valve seat 172b to apply upward force. The valve 172 also starts rising.

In this case, since the inside of the liquid chamber 140b and the inside of the gas chamber 140a become a negative pressure lower than the atmospheric pressure as described above, the first check ball 171a of the first check valve 171 is the first check valve seat ( Spaced apart from 171b to open the inlet of the liquid chamber 140b, and the outer valve member 173b of the third check valve 34 is spaced inwardly toward the inner surface of the horizontal plate member 117b. The suction hole 181 is opened. On the other hand, the inner valve member 173c of the third check valve 34 has an annular protrusion (2) in which the pressurized state inside the gas chamber 140a is released and its inner edge is coupled / formed to the outer surface of the liquid piston 110b. 117) The gas passage O is closed in contact with the upper surface. Accordingly, the expandable liquid A in the liquid absorbing tube 183 and the container 10 flows into the liquid chamber 140b and the gas in the upper space on the upper surface side of the gas piston 110a into the gas chamber 140a. Is inhaled.

In this case, since the gas passage O is closed as described above, bubbles in the mixing chamber 140c do not enter the gas chamber 140a along the gas passage O.

The pistons 110a and 110b, the nozzle portion 160 and the rod-shaped second check valve 172 are no longer raised in the maximum raised position shown in FIG. By repeatedly pressing and releasing the pressing of the nozzle unit 160, a predetermined amount of foam can be discharged intermittently.

Even if the container 10 is inverted or dropped in the state of FIG. 1, when the nozzle unit 160 is locked in the locked state and the nozzle unit 160 does not slide upward and downward, the mixing chamber 140c of the liquid passage The outlet port, which is the side outlet, prevents the rise by the cylindrical stopper 185 from the second valve sealing portion 172c surrounding the outlet port of the upper end of the liquid piston that is elastically pressurized upward by the spring 191. Since the second valve seat 172b of the rod-shaped second check valve 172 is in close contact with each other, the mixing chamber 140c is not leaked to the outside of the container 10 because the liquid in the fluid passage does not leak out. It does not penetrate into the gas chamber 140a via). In this case, since the gas piston ring member 115a of the gas piston 110a closes the gas hole 187, the liquid in the container 10 is not only the gas chamber 140a in the gas hole 187 but also the gas. It does not penetrate into the cylinder 133a, either.

In addition, since the inward edge of the inner valve member 173c of the third check valve 173 is in contact with the upper surface of the annular protrusion 117 of the liquid piston 110b, the inlet of the gas passage O is closed. Even if the bubbles remaining in the passage and the mixing chamber 140c pass for a long time, the liquid can be prevented from flowing into the gas chamber 140a.
