  When the head portion 16 is pushed down toward the mounting cap 11, the pistons 14c and 14d are pushed downward by the shaft portion 15 and the pump P performs a discharge operation. When the pump P discharges, the contents stored in the container 12 are pumped to the flow path 15a through the suction pipe 18 and the small diameter cylinder chamber 14a, and air is pumped from the large diameter cylinder chamber 14b to the flow path 15a. And these are mixed in the flow path 15a. Further, the shaft portion 15 is provided with a mesh M, and when the mixture of the content and air passes through the mesh M, the content is made into a foam-like shape and passes through the discharge flow channel 16a from the flow channel 15a. It is discharged from the discharge nozzle 21 to the outside. In this way, by pressing down the head portion 16, the contents stored in the container 12 can be discharged to the outside. When the push-down operation of the head portion 16 is released, the pistons 14c and 14d are pushed upward by the spring 22 disposed in the cylinder chamber 14a, whereby the head portion 16 returns to the initial position.

  As shown in FIG. 1, the ejector 10 includes a stopper member 23 that restricts the pressing operation of the head portion 16, that is, prevents the head portion 16 from being pressed.

  A support member 24 is connected to the head portion 16, and the stopper member 23 is attached to the support member 24. The support member 24 is formed in a cylindrical shape coaxial with the shaft portion 15, is connected to the lower surface of the head portion 16, and protrudes from the lower surface toward the mounting cap 11. In the case shown in the figure, the support member 24 is formed of a resin material integrally with the head portion 16 and is connected to the head portion 16. However, the support member 24 is formed separately from the head portion 16, so It can also be set as the structure connected to the head part 16 using fixing means, such as a cut.

  The stopper member 23 is formed of a resin material into a cylindrical shape having an inner diameter slightly larger than the outer diameter of the support member 24, and is attached to the outside of the support member 24. The stopper member 23 is in sliding contact with the outer peripheral surface of the support member 24 on the inner peripheral surface thereof, and can be relatively moved in a direction approaching and moving away from the head portion 16 while being guided by the outer peripheral surface of the support member 24. It is like that. That is, the stopper member 23 can move relative to the support member 24 along the moving direction of the head portion 16.

  A locking mechanism 25 is provided between the stopper member 23 and the support member 24 in order to restrict the stopper member 23 from moving in a direction approaching the head portion 16. The locking mechanism 25 includes an engaging portion 26 provided on the support member 24 and a locking claw 27 provided on the stopper member 23.

  As shown in FIG. 3, the side surface of the support member 24 is provided with a recess 24 a that is recessed with respect to the outer peripheral surface thereof. The recess 24a extends from the upper end to the lower end of the outer peripheral surface along the axial direction of the support member 24, and an engagement portion 26 is provided inside the recess 24a. In the present embodiment, the recess 24a is provided on a portion of the outer peripheral surface of the support member 24 facing the opposite side (right side in FIG. 1) to the direction in which the discharge nozzle 21 protrudes (left side in FIG. 1). . For convenience, in FIG. 3, only specific protrusions 28 are denoted by reference numerals.

  The engaging portion 26 includes a plurality of protrusions 28, and these protrusions 28 are arranged in the recess 24 a at equal intervals along the axial direction of the support member 24, that is, the movement direction of the stopper member 23 relative to the support member 24. Yes. As shown in FIG. 4, each projection 28 has a triangular cross section and is formed in a shape extending parallel to a direction orthogonal to the axial direction of the support member 24, and the surface facing the mounting cap 11 is a stopper member. The engaging surface 28 a is perpendicular to the moving direction of the movement 23.

  On the other hand, as shown in FIG. 1, the stopper member 23 is integrally provided with a locking piece 29. The locking piece 29 is connected to the stopper member 23 by a hinge 30 parallel to a direction orthogonal to the axial direction of the support member 24, and is rotatable in a direction approaching / separating from the support member 24 around the hinge 30. It has become. This locking piece 29 can be provided as a part between these slits, for example, provided in the stopper member 23 with a pair of parallel slits extending along the axial direction from the upper end edge facing the head portion 16 side.

  The locking claw 27 is integrally provided on the inner peripheral surface facing the support member 24 at the tip of the locking piece 29 provided on the stopper member 23. As shown in FIG. 4, the locking claw 27 is formed in a triangular cross section that is vertically opposite to the protrusion 28 of the engaging portion 26, and the surface facing the head portion 16 is the movement of the stopper member 23. The locking surface 27a is perpendicular to the direction. The locking claw 27 engages with the engaging surface 28a of the protrusion 28 of the engaging portion 26 at the locking surface 27a. As a result, the movement of the stopper member 23 in the direction approaching the head portion 16 is restricted by the locking mechanism 25, and the head portion 16 cannot be pushed down.

  Since the locking claw 27 engages with the engaging surface 28a of the protrusion 28 inside the recess 24a of the support member 24, the locking claw 27 is guided by the inner wall of the recess 24a, and the stopper member 23 is supported by the support member 24. Against rotation. In addition, it can also be set as the structure which provides the rotation prevention with respect to the support member 24 of the stopper member 23 separately.

  A knob 31 is integrally provided on the outer circumferential surface of the locking piece 29, and an auxiliary knob 32 corresponding to the knob 31 is integrally provided on the outer circumferential surface of the stopper member 23 below the hinge 30. The knob 31 and the auxiliary knob 32 are formed in a plate shape parallel to each other. When the knob 31 is pushed down toward the auxiliary knob 32, the locking piece 29 is rotated outward about the hinge 30. Thus, the locking claw 27 can be detached from the engaging surface 28a of the protrusion 28. When the locking claw 27 is disengaged from the engaging surface 28 a of the protrusion 28, the restriction of the movement of the stopper member 23 is released, and the stopper member 23 can be moved in the direction approaching the head portion 16.

  On the other hand, as shown in FIG. 4, the surface of the protrusion 28 facing the head portion 16 is an inclined surface 28 b that is inclined with respect to the moving direction of the stopper member 23. The surface facing the side is also an inclined surface 27b inclined with respect to the moving direction. Therefore, when the stopper member 23 is moved away from the head portion 16, the inclined surface 27b of the locking claw 27 gets over the inclined surface 28b of the projection 28 while elastically deforming the locking piece 29 outward. Can do. That is, the engaging portion 26 and the locking claw 27 restrict the movement of the stopper member 23 in the direction approaching the head portion 16, but allow the movement of the stopper member 23 in the direction away from the head portion 16. It is configured. Therefore, when the stopper member 23 is moved in the direction approaching the mounting cap 11, the stopper member 23 can be moved in that direction without operating the locking piece 29. The resistance force generated between the stopper member 23 and the support member 24 during this movement is preferably set to a value that does not exceed the biasing force of the spring 22. Note that the ratchet is a mechanism used to limit the operation direction to one side.

  With such a configuration, the stopper member 23 attached to the support member 24 can be moved relative to the support member 24 in a direction approaching or moving away from the head portion 16 and can be held at the position by the locking mechanism 25. .

  As shown in FIG. 5, the stopper member 23 is moved to the lower stroke end with respect to the support member 24 and held in that position by the locking mechanism 25, so that the natural state, that is, the head portion 16 is pushed down. In a state where it is not, the lower end of the stopper member 23 can be brought into contact with the top wall 11 b of the mounting cap 11. In this state, the stopper member 23 is in the stopper position, and the head portion 16 is supported by the mounting cap 11. Therefore, the movement of the head portion 16 toward the mounting cap 11, that is, the pressing operation of the head portion 16 is restricted. Therefore, by setting the stopper member 23 to the stopper position, the head unit 16 can be in a state where it cannot be pushed down.

  The top wall 11b of the mounting cap 11 is provided with a circular pedestal portion 33 protruding toward the head portion 16 side, and the inner peripheral surface of the stopper member 23 at the stopper position engages with the outer peripheral surface of the pedestal portion 33. To do. Thereby, the vibration of the stopper member 23 at the time of conveyance etc. can be prevented.

  When the restriction of the pressing operation of the head portion 16 by the stopper member 23 is released, as shown in FIG. 6, the knob 31 and the auxiliary knob 32 are gripped with fingers, and the hinge 30 is the center. The locking piece 29 is rotated outward, and the locking claw 27 is detached from the engaging surface 28 a of the protrusion 28. Then, the stopper member 23 can be moved in a direction to approach the head portion 16 while holding the knob 31 and the auxiliary knob 32.

  As shown in FIG. 7, when the stopper member 23 is moved to the full stroke position closest to the head portion 16, and the hand is released from the knob pieces 31, 32, the locking piece 29 returns to the initial position due to its elastic deformation. Then, the locking claw 27 engages with the engaging surface 28a of the uppermost protrusion 28 of the engaging portion 26, and the stopper member 23 is held at this position. The full stroke position of the stopper member 23 is a release position where the stopper member 23 is separated from the mounting cap 11 and the restriction of the pressing operation of the head portion 16 is released. In a state in which the stopper member 23 is held at the full stroke position, the pump 16 is discharged by operating the head portion 16 toward the mounting cap 11 to discharge the contents stored in the container 12. Can be discharged to the outside.

  As described above, in the present invention, the pressing operation of the head portion 16 is restricted by the stopper member 23 attached to the support member 24, and the restriction can be released by moving the stopper member 23 by the operation of the locking mechanism 25. Therefore, the stopper member 23 can be integrated with the discharger 10 to prevent the stopper member 23 from being lost.

  Further, in the present invention, the stopper member 23 and the support member 24 are formed in a cylindrical shape, and the stopper member 23 is slidably mounted on the outside of the support member 24. Therefore, the stopper member 23 is attached to the support member 24. It can be reliably supported. Thereby, the movement of the stopper member 23 with respect to the support member 24 can be smoothed, and the stopper member 23 can be reliably restricted from pushing down the head portion 16.

  As shown in FIG. 7, in a state where the stopper member 23 is held at the full stroke position, the head portion 16 can be operated at the full stroke, that is, the push-down amount is maximized.

  On the other hand, for example, the stopper member 23 can be held by the support member 24 at an arbitrary position between the stopper position and the full stroke position as shown in FIG. That is, the stopper claw 27 provided on the stopper member 23 is engaged with the engagement surface 28a of the arbitrary protrusion 28 of the engagement portion 26 provided on the support member 24, whereby the stopper member 23 is set to the stopper position. The support member 24 can be held at an arbitrary position between the full stroke positions. By holding the stopper member 23 on the support member 24 at an arbitrary position between the stopper position and the full stroke position, the distance between the lower end of the stopper member 23 and the mounting cap 11 in the natural state is arbitrarily set, and the head The pressing stroke of the portion 16 can be adjusted in multiple stages. In the present embodiment, since the engaging portion 26 is provided with nine protrusions 28 in addition to the protrusion 28 corresponding to the stopper position, the pressing stroke of the head portion 16 is divided into nine stages including the full stroke. Can be adjusted.

  Thus, in the present invention, since the stopper member 23 can be locked at an arbitrary position of the support member 24, the head portion 16 is pushed down by adjusting the push-down stroke of the head portion 16 in multiple stages. Sometimes the discharge amount of the content discharged from the discharge nozzle 21 can be changed as required.

  Further, in the present invention, the engaging portion 26 is disposed on the portion of the support member 24 facing the side opposite to the protruding direction of the discharge nozzle 21, so that the discharge amount is adjusted by moving the stopper member 23. Alternatively, when the discharge is regulated or released, the discharge nozzle 21 does not interfere with the operation of the locking piece 29, and the operation is easy.

  After the contents are discharged from the container 12, the stopper member 23 can be moved to the stopper position again to restrict the pressing operation of the head portion 16. At this time, since the locking mechanism 25 is configured as a ratchet, the stopper member 23 can be moved to the stopper position by simply pressing the stopper member 23 downward without operating the locking piece 29. Can be made.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, in the above-described embodiment, ten protrusions 28 (engagement surfaces 28a) are provided on the engaging portion 26. However, the number of protrusions 28 provided on the engaging portion 26 is not limited to this. It can be set arbitrarily.

  In the above embodiment, one surface of the protrusion 28 provided on the support member 24 is used as the engagement surface 28a. However, the support member 24 is provided with a plurality of recessed portions arranged in the moving direction of the stopper member 23. The inner surface may be an engagement surface.

  Furthermore, in the above-described embodiment, the stopper member 23 and the support member 24 are formed in a cylindrical shape. However, the present invention is not limited to this, and the stopper member 23 can be mounted on the support member 24 in a relatively movable manner. For example, the stopper member 23 and the support member 24 may be formed in a cylindrical shape having a square cross section, or may be formed in other shapes such as a C-shaped cross section.

  Furthermore, in the embodiment, the engaging portion 26 and the locking claw 27 are configured as a ratchet. However, the present invention is not limited to this, and for example, the protrusion 28 and the locking claw 27 are both formed in a rectangular cross section. For example, the movement of the stopper member 23 in any direction approaching or moving away from the head portion 16 may be restricted.

  Further, in the above embodiment, a former type pump is used as the pump P. However, the present invention is not limited to this, and the pump is configured to discharge the contents by pushing down the head portion 16 toward the mounting cap 11. If so, pumps of other configurations can be used.

  Further, in the embodiment, the knob 31 and the auxiliary knob 32 are provided for the operation of the locking piece 29, but only the knob 31 may be provided. Further, the shape of the knob 31 is not limited to that shown in the drawing, and various shapes can be used as long as the locking piece 29 can be operated.
