  On the other hand, the lower portion of the cylinder 12 is continuously provided with a suction port 12g and a pipe attachment port 12h inside the position of the third step portion 12d. And the upper end part of the pipe 13 is press-fit in the pipe attachment port 12h, and the inside of the pipe 13 and the suction port 12g are connected. On the other hand, a valve seat 12i that gradually decreases in diameter toward the lower side is provided immediately above the suction port 12g.

  In such a cylinder 12, a ball-shaped check valve 19 is placed and placed on the valve seat 12i, and then a coil spring 20 is inserted and placed on the third step portion 12d. Thereafter, the stem 21 having the on-off valve 22 and serving as a piston is inserted.

  The stem 21 has a tubular shape and is provided with two step portions a and b in the inside thereof, and is provided with an ejection path 21a which is concentric and gradually decreases in diameter toward the lower side in the figure, and communicates with the ejection path 21a in a radial direction. 21b is provided, and a circumferential groove is formed on the outer periphery of the position of the lateral hole 21b.

  On the other hand, the on-off valve 22 has a cylindrical shape, and is provided with an annular convex portion 22a protruding inward from the inner surface at an intermediate portion. The annular convex portion 22 a is fitted into the circumferential groove, and the outer peripheral upper and lower portions of the on-off valve 22 are slidably pressed against the inner peripheral surface of the cylinder 12.

  Now, in the stem 21, an elevating member 23 made of a resin such as polyethylene or polypropylene and formed in a ball shape is inserted and placed on the upper stage a of the ejection path 21a.

  Incidentally, a color ring 25 is provided at the upper end of the cylinder 12. The coloring ring 25 is formed by concentrically and integrally forming an outer cylinder part 25a and an inner cylinder part 25b. Then, the inner cylinder portion 25b is inserted into the cylinder 12, the lower end is abutted against the upper end of the on-off valve 22, the coil spring 20 is slightly compressed via the stem 21, and the outer cylinder portion 25a is replaced with the upper end portion 12f of the cylinder 12. It is hung on the top.

  As a result, the stem 21 is pushed up by the biasing force of the coil spring 20, and the lower step portion of the circumferential groove is pressed against the lower surface of the annular convex portion 22 a of the on-off valve 22 to communicate between the ejection passage 21 a and the cylinder chamber 28. Shut off. The stem 21 protrudes upward through the inner cylindrical portion 25 b of the coloring ring 25. At the upper end of the stem 21, a support member 26 that also serves as a push button as an operation member is attached.

  The support member 26 is provided with a jet pipe 26b on the outer periphery of the button-shaped main body part 26a in a bowl shape, and a cylindrical part 26c is provided downward in the center of the main body part 26a, and the space between the cylindrical part 26c and the jet pipe 26b is horizontally long. A discharge path 26e is formed inside by connecting with the cylindrical portion 26d and extending from the lower end of the cylindrical portion 26c to the tip of the ejection pipe 26b. At the tip of the ejection pipe 26b, a communication path 26f is formed by cutting upward from the discharge path 26e toward the outer periphery. Then, the upper end portion of the stem 21 is press-fitted into the cylindrical portion 26c, the discharge path 26e and the ejection path 21a are communicated, and the cosmetic liquid discharged from the container 10 passes from the ejection path 21a through the discharge path 26e, and the communication path From 26f, it puts into the injection member 27 attached to the front-end | tip of the ejection pipe | tube 26b.

FIG. 2A shows an enlarged vertical section of a support member provided with the ejection member, which is provided in the ejector. (B) shows the injection member as seen from the injection direction.
As can be seen from FIGS. 2A and 2B, the injection member 27 has an oval cross-sectional shape, a fitting hole 27a is provided at the center of one end surface, and nozzle member mounting holes 27b and 27c are provided at symmetrical positions on the other end surface. The fitting hole 27a and one nozzle member attachment hole 27b communicate with each other through a passage 27d, and the fitting hole 27a and the other nozzle member attachment hole 27c communicate with each other through a passage 27e.

  Then, the nozzle member 30 is press-fitted into one nozzle member attachment hole 27b, and another nozzle member 31 is press-fitted into the other nozzle member attachment hole 27c. The injection ports 30a and 31a are opened at the centers of the tops of the nozzle members 30 and 31, respectively. A spiral groove is formed on the top inner surface 30 b of the nozzle member 30. On the top outer surface, a cosmetic liquid injection direction restricting projection 30c is formed in the radial direction.

  On the other hand, the tip of the ejection pipe 26b of the support member 26 is press-fitted into the fitting hole 27a, the injection member 27 is attached to the support member 26, and the injection member 27 is rotated to arbitrarily change the attachment position with respect to the support member 26. The discharge passage 26e and the passage 27d or the passage 27e are communicated with each other via the communication passage 26f so that one of the injection ports 30a and 31a can be selectively communicated with the discharge passage 26e.

  Here, in order to prevent the ejection member 27 from easily falling off from the support member 26, for example, a recess may be formed on one side with the support member 26, and a projection that fits into the recess may be formed on the other side. The recess may be formed in an annular shape so that it can be easily rotated.

  Further, it is possible to easily recognize that the discharge passage 26e communicates with the passage 27d or the passage 27e via the communication passage 26f, and the injection member 27 is attached so that the attachment position of the injection member 27 with respect to the support member 26 does not become unstable. It is preferable to feel a click when the exhaust passage 26e and the passage 27d or the passage 27e communicate with each other. The shape of the ejection member 27 may be devised or a mark may be provided so that the appearance can be recognized.

  Now, when this ejector is used, when the injection member 27 is picked and rotated with respect to the support member 26 and the cosmetic liquid is sprayed in the form of a mist, one nozzle member 30 is turned up and the communication passage 26f. The discharge path 26e and the path 27d are communicated via Then, the stem 21 is pushed into the cylinder 12 by placing the hand on the main body portion 26a of the support member 27 with the injection port 30a directed toward the target portion and pushing it down against the coil spring 20 in the direction of arrow A in FIG. Then, due to frictional resistance with the inner surface of the cylinder 12, the stem 21 moves at the position where the on-off valve 22 is left as it is, and the upper step of the circumferential groove contacts the upper surface of the annular convex portion 22 a of the on-off valve 22.

  As the stem 21 is pushed in, the on-off valve 22 is deformed to open the lateral hole 21b, and the cylinder chamber 28 and the ejection passage 21a are communicated with each other, while the pressure in the cylinder chamber 28 is increased and the cosmetic liquid in the cylinder chamber 28 is increased. Is sent to the ejection path 21a through the horizontal hole 21b, and the cosmetic liquid is passed through the lifting member 23 into the discharge path 26e while receiving the flow of the cosmetic liquid and ascending the lifting member 23 against gravity, and the discharge path 26e. Is passed through the communication passage 26f into the passage 27d, and the cosmetic liquid is sprayed from the injection port 30a to the outside in the form of a mist.

  When changing the spray pattern and spraying the cosmetic liquid from the other nozzle member 31 in a straight line, the spray member 27 is picked and rotated 180 degrees with respect to the support member 26, with the other nozzle member 31 facing up. The discharge passage 26e and the passage 27e are communicated with each other through the communication passage 26f. Then, the body portion 26a of the support member 27 is pushed down with the injection port 31a directed toward the target portion, the stem 21 is pushed into the cylinder 12, the on-off valve 22 is deformed to open the lateral hole 21b, and the cosmetic liquid in the cylinder chamber 28 is opened. Is put into the discharge passage 26e, passes through the discharge passage 26e, is put into the passage 27e from the communication passage 26f, and the cosmetic liquid is ejected to the outside in a continuous straight line shape from the injection port 31a.

  When the final pressing stage shown in FIG. 3 is reached, when the release is released by releasing the hand from the support member 26, the stem 21 is pushed up by the coil spring 20 in the direction of arrow B in the figure. Then, the stem 21 moves when the on-off valve 22 remains in position due to the frictional resistance with the inner surface of the cylinder 12, and the communication between the ejection passage 21a and the cylinder chamber 28 is blocked by closing the lateral hole 21b with the inner surface of the annular convex portion 22a. Then, the lower step portion of the circumferential groove is brought into contact with the lower surface of the annular convex portion 22 a of the on-off valve 22.

  Then, when the on-off valve 22 is slid together with the stem 21 to return to the state shown in FIG. 1, the inside of the cylinder chamber 28 is made negative pressure, the check valve 19 is opened, and the cosmetic liquid in the container 10 is discharged from the suction port 12g. Suck into the cylinder chamber 28. Further, when the ejection is stopped, the flow of the cosmetic liquid in the ejection path 21a is stopped, and the resin lifting member 23 is lowered by gravity and returned to the step a.

  As a result, the cosmetic liquid remaining near the injection ports 30a and 31a is sucked in and dripping from the injection ports 30a and 31a, or the residual cosmetic liquid is dried and solidified over time to narrow the injection ports 30a and 31a. For example, it is possible to prevent the occurrence of troubles such as smearing the user's clothes, for example, by spraying the cosmetic liquid in an unexpected direction.

  In the example described above, the injection member 27 is provided with the two injection ports 30a and 31a having different injection patterns, but of course, the number of injection ports is not limited to two and may be three or more. It is not limited to a mist or continuous straight line, but may be a bubble.

  By the way, in the above-described example, the case where the support member 26 also serves as a push button that is an operation member, and the hand member is pushed down to discharge the cosmetic liquid in the container 10 and lead it to the discharge path 26e has been described. However, as shown in FIG. 4, the present invention can be similarly applied to a trigger-type ejection device that discharges the contents of the container 10 by placing the hand on the trigger lever 33, which is an operation member, and pushing it down to guide it to the discharge path. it can.

  That is, a support member 26 having a discharge path through which the contents discharged from the container 10 pass and a plurality of injection ports having different injection patterns are provided, attached to the support member 26, rotated and attached to the support member 26. And an injection member 27 that allows the position to be arbitrarily moved to selectively communicate one of the plurality of injection ports with the discharge path.

  Then, the injection member 27 is rotated to arbitrarily change the attachment position with respect to the support member 26, one of the plurality of injection ports of the injection member 27 is selectively communicated with the discharge path of the support member 26, and the trigger lever 33 By operating the, the contents discharged from the container 10 pass through the discharge path and are ejected to the outside with an ejection pattern corresponding to the selected ejection port.

  In the above-described example, the pump-type spraying device P that reciprocates the stem 21 that also serves as the piston and ejects the cosmetic liquid in the container 10 to the outside by pushing down the support member 26 that also serves as the push button that is the operation member. The case where it applied to the pump type ejector provided with was demonstrated. However, the same applies to an aerosol type ejector equipped with an ejection device that opens an outlet valve by operating an operation member such as a push button or a trigger lever, and injects the contents of the container to the outside with the pressure of the injection material. Can do.

  That is, as shown in FIG. 5, a support member 26 having a discharge path through which the contents discharged from the container 10 pass and a plurality of injection ports having different injection patterns are provided and attached to the support member 26, and the support member And an injection member 27 that can arbitrarily move one of the plurality of injection ports to the discharge passage.

  And the injection member 27 is moved, the attachment position with respect to the support member 26 is arbitrarily changed, and one of the plurality of injection ports of the injection member 27 can be selectively communicated with the discharge path of the support member 26. By depressing the supporting member 26 that also functions as a certain push button, the stem 40 of the spray device R for the aerosol type ejector is pushed to deform the stem rubber (exit valve) 41 to open the communication hole 40a of the stem 40, and the container 10 The contents of the container 10 and the contents are put into the discharge path 40b of the stem 41 from the communication hole 40a by the pressure of the propellant stored in the container 10, and the contents discharged from the container 10 are selected through the discharge path. Injecting from the injection port to the outside with an injection pattern corresponding to the injection port.

  Further, the present invention can be similarly applied to an extrusion-type ejector in which an ejection device for an extrusion-type ejector is attached to a mouth portion of a container and the contents of the container are ejected to the outside by crushing the container.

  And the injection member is moved, the attachment position with respect to the support member is arbitrarily changed, one of the injection ports of the injection member can be selectively communicated with the discharge path of the support member, and the container is crushed from the container by crushing The content to be discharged passes through the discharge path and is ejected to the outside in an ejection pattern corresponding to the selected ejection port.
