【Example】

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show an embodiment of the present invention, and in the figures, 1 indicates a liquid dispensing container. the container 1 is composed of a container body 2 and a vertical pump 3 attached to the container body 2, This vertical pump is provided with a stroke conversion mechanism 4.

[0006] The container body 2 is made of synthetic resin or the like, and has a mouth and neck part 6 standing up from a body part 5. Ru.

[0007] Further, the vertical pump 3 is constructed with a cylinder member 7 and an operating member 8 as main members. has been completed. Further, the cylinder member 7 has a cylindrical shape with open upper and lower end surfaces, and a circumference. An outward flange 9 is provided protruding from the upper part of the outer periphery of the wall, and a ball-shaped valve body is provided at the inner lower end. A cylinder 11 provided with a suction valve 10, and a cylinder 11 that hangs down from the inner periphery of the upper end of the cylinder 11. An outward flange-shaped top wall 13 is extended from the upper end edge of the guide cylinder 12, and A fitting in which the peripheral wall 14 is suspended from the outer peripheral edge of the top wall 13 and is suspended from the center of the back surface of the top wall 13. An auxiliary cap 16 formed by fitting a joint tube 15 onto the outer periphery of the upper end of the cylinder 11; Rotatable between the fitting tube 15 of the cap 16 and the outward flange 9 of the cylinder 11 A mounting cylinder having a thread threaded on the inner peripheral surface from the outer peripheral edge of the fitted inward flange-shaped top wall 17. It consists of a mounting cap 19 with a part 18 hanging down. Then, the lower end of the cylinder 11 is suspended into the container body 2, and the cylinder The outward flanges 9 of 11 are placed on the upper surface of the container mouth neck 6 via the packing 20. Furthermore, the inner surface of the mounting cylinder portion 18 of the mounting cap 19 is screwed onto the outer periphery of the container mouth neck portion 6. This allows the cylinder member 7 to be attached to the container body 2.

[0008] The actuating member 8 also includes a coil spring 21 provided at the lower part of the cylinder 11. The upper end of the cylinder 11 is kept above the upper end opening of the cylinder 11. A cylindrical stem 22 that protrudes so as to be movable downward, and is fitted to the outer periphery of the upper end of this stem 22. a push-down head 24 with a nozzle 23 and an annular pin provided at the bottom of the stem 22. It is composed of Stone 25. Further, the piston 25 is located on the inner surface of the cylindrical base. The upwardly protruding skirt portion contacts the outer peripheral surface of the stem 22 in a fluid-tight and slidable manner. At the same time, the upward and downward skirts protruding from the outer surface of the base are connected to the cylinder. -11 is mounted in liquid-tight and slidable contact with the inner surface. Also, this piston 2 5 includes an outward flange 26 protruding from the outer periphery of the lower end of the peripheral wall of the stem 22; 26 is provided on the circumferential wall of the stem above the flange 26 at a predetermined distance. It is installed between the locking protrusions, and when the actuating member is pressed down, the top surface of the cylindrical base touches the locking protrusions. When the actuating member 8 is pushed down and raised by the action of the spring 21, the cylindrical The lower surface of the base is pushed upward by the upper surface of the outward flange 26. . Furthermore, a pair of through holes 2 are provided in the lower part of the stem peripheral wall between the locking protrusion and the outward flange 26. 7 is bored to communicate the inside and outside of the stem 22.

[0009] In the vertical pump 3 as described above, when the operating member 8 is lowered, the outer periphery of the stem 22 is locked. The protrusion pushes down the annular piston 25 and drains the liquid in the cylinder 11 below the piston 25. Pressure is applied, and at this time, a gap is created between the lower end of the piston 25 and the above-mentioned outward flange 26. Therefore, the liquid in the cylinder below the piston 25 passes through the stem 22 through the through hole 27. , so that it is poured out from the spout 29 of the nozzle 23. Also, the operating part When the material 8 rises, the outward flange 26 on the outer periphery of the stem 22 pushes up the annular piston 25. At this time, the piston closes the through hole 27, so the cylinder at the bottom of the piston 25 The pressure inside the cylinder 11 becomes negative, the suction valve 10 opens, and the liquid inside the container body 2 is transferred to the cylinder 1. Therefore, due to the vertical movement of the push-down head 24, the liquid in the container body 2 is It is constructed so that it is sequentially poured out from the spout of the nozzle 23.

0010 Further, the stroke conversion mechanism 4 includes a pair of engagement parts provided on the auxiliary cap 16. It consists of a protrusion 28 and a locking protrusion 29 provided on the stem 22. The engagement protrusion 28 is provided protruding from the lower part of the inner peripheral surface of the guide tube 12 of the auxiliary cap 16. It is structured as a vertically long protrusion. Further, the locking protrusion 29 is located at the lower part of the outer circumference of the stem 22. The engaging protrusion 28 can be inserted into the front and rear of the circumferential band-shaped protrusion by recessing its upper surface. A pair of concave portions are formed, and a pair of high portion locking end surfaces 30 are formed on the left and right sides, and a pair of high portion locking end surfaces 30 are formed on the left and right sides. It is configured to have a lower locking end surface 31. And the actuating member 8 is the nozzle. 23 protrudes forward, the lower end surface of each engaging protrusion 28 is aligned with each lower end of the locking protrusion 29. The vertical stroke width of the actuating member 8 is set wide by contacting with the locking end surface 31, and the operation When the movable member 8 is rotated 90 degrees in the horizontal direction and the nozzle 23 is protruded to the side, , the lower end surface of each engaging protrusion 28 comes into contact with each high locking end surface 30 of the locking protrusion 29 to operate. The vertical stroke width of the member 8 is configured to be narrow. In this embodiment, the engagement protrusion 28 is attached to the mounting cap 16 of the cylinder member 7. Although the locking protrusions 29 are provided on each stem 22, the opposite may be used. Also, books In the example, the locking end surface of the locking protrusion is set in two stages, but it may be set in three or more stages. It is also possible to do so.
