  5 and 6 show an example in which the mesh molded body A is used for the foam discharger B. FIG.

  The foam discharger B is configured to be detachably mounted on the container body 100 by a mounting cap 20 fitted to the mouth / neck portion 101. A cylinder member 30 is suspended from the lower surface of the mounting cap 20. The cylinder member 30 has an upper end fitted and fixed to the lower surface of the mounting cap 20, and a small diameter liquid cylinder 31 is disposed below the large diameter air cylinder 31. The cylinder 32 extends concentrically. Further, the upper end of the suction pipe 33 is fitted into a pipe fitting cylinder that is integrally suspended from the lower end of the liquid cylinder 32, and the lower end is suspended from the lower end portion in the container body 100.

  Further, the operating member 40 is provided so as to be movable up and down in an upward biased state with respect to the cylinder member 30. The actuating member 40 is provided with a liquid piston 42 that slides on the inner periphery of the liquid cylinder 32 at the lower outer periphery of the stem 41, and an air piston that slides on the inner periphery of the air cylinder 31 at the middle in the vertical direction of the outer periphery of the stem 41. 43. A discharge head 45 is fitted and fixed to the upper end of the stem. The coil spring s is always biased upward.

  A discharge valve 46 is provided in the upper portion of the stem 41, and an air passage 47 extending from the air cylinder 31 to the stem 41 downstream of the discharge valve 46 is provided. The position is a gas-liquid mixing chamber R.

The air piston 43 has an inner peripheral edge fitted to the outer circumference of the stem 41 so as to allow a small vertical movement, and an outer peripheral edge is fitted to the inner circumference of the air cylinder 31 so as to be capable of being fluid-tightly slidable. An air discharge valve 48 is constituted by the inner peripheral edge of the air piston 43 and the valve seat protruding from the stem 41. The air discharge valve 48 is closed when the operating member 40 is pushed upward, opens when the operating member 40 is pushed down, and further rises by the upward biasing force from the pushed-down state. In some cases, it is configured to close. The air piston 43 is provided with an outside air introduction valve 49 for introducing outside air. Outside air introduction valve 49, the air cylinder 31 when lowering the actuating member 40 is raised is opened by a negative pressure, introducing the outside air.

  A poppet valve body 60 is provided in the liquid cylinder, and a suction valve 61 is formed by a peripheral surface of the lower surface and a valve seat for the suction valve at the bottom of the liquid cylinder 32 and is mounted so as to be movable up and down. . A check valve 62 is formed by the upper end portion of the poppet valve body 60 and the valve seat for the check valve in the stem 41.

  The discharge head 45 hangs a vertical cylinder 70 fitted to the outer peripheral upper end of the stem 41 from the top plate back surface, and opens a base end at the upper end of the vertical cylinder 70 to extend the nozzle 71 forward. A discharge port is opened at the tip.

  A foaming member 80 formed of the mesh molded body A of the present invention is provided downstream of the gas-liquid mixing chamber R. The foaming member 80 is mounted in the liquid flow path downstream of the gas-liquid mixing chamber R via a cylinder 81 fitted in the vertical cylinder 70 of the discharge head 45. As shown in the enlarged view of the main part in FIG. 6, the first mesh 10 and the second mesh 11 are stacked and fixed on the inner periphery of the vertical cylinder 70 by fitting the fitting portion 16 to the fitting portion 15. The foamed member 80 is formed by fitting and fixing the mesh molded body A.

  A spacer 90 is detachably mounted between the lower surface of the ejection head 45 and the upper surface of the mounting cap 20.

In the bubble discharger B, when the spacer 90 is removed from the state of FIG. 1 and the discharge head 45 is pushed down, the air piston rises relative to the stem 41 and the air discharge valve 48 opens and moves down. Air in the air cylinder 31 is pressurized by the piston 43 and introduced into the gas-liquid mixing chamber R through the air passage 47. On the other hand, the liquid cylinder 32 is lowered and lowered until the poppet valve body 60 is brought into contact with the valve seat for the suction valve, and the poppet valve body 60 is raised relative to the stem 41 to check valve 62. Is opened, and the pressurized liquid in the liquid cylinder 32 is introduced into the gas-liquid mixing chamber via the discharge valve 46, where the gas-liquid is mixed. At this time, the poppet valve body 60 rises relative to the stem 41. The gas-liquid mixed in the gas-liquid mixing chamber R passes through the foaming member 80 and foams, is introduced into the discharge head 45, and is discharged outside. Since the foaming member 80 has a laminated structure of the first mesh 10 and the second mesh 11 formed of the mesh molded body A, it is possible to form fine bubbles and to discharge fine bubbles.

When the pressure of the discharge head 45 is released, the actuating member 40 is lifted by the biasing force of the coil spring s. At this time, the air piston 43 is lowered relative to the stem 41, and the air discharge valve 48 is closed. Due to the negative pressure in the cylinder 31, the outside air introduction valve 49 is opened and outside air is introduced into the air cylinder 31. On the other hand, the poppet valve body 60 is raised by the rise of the stem 41, and the liquid in the container body 100 is introduced into the liquid cylinder 32 that is opened and the suction valve 61 is made negative, and the discharge valve 46 is closed at that time.

  FIG. 7 shows a second embodiment of the mesh molded body A, and this example shows an example in which the first mesh 10 and the second mesh 11 are formed separately.

  In the illustrated example, the mesh molded body A is formed by the first mesh molded body A1 in which the first mesh 10 is stretched and the second mesh molded body A2 in which the second mesh 11 is stretched.

  As shown in FIG. 7A, the first mesh molded body A1 is provided with a cylindrical fitting portion 16a with an engaging rib 17 vertically provided on the outer surface from one end face of the first support cylinder 12a. The first mesh 10 is stretched at the tip of the fitting portion 16a. Although the engagement ribs 17 in the illustrated example protrude at four positions at equal intervals, the present invention is not limited to this.

  Further, in FIG. 7B, the second mesh molded body A2 is in an inverted state, and includes a second support cylinder 13a formed on the fitted portion 15a that fits the inner surface with the fitted portion 16a. The second mesh 11 is stretched on the inner surface of the support cylinder 13a.
