DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a cream-like substance discharging container. The container 1
Comprises a container body 2, a cylinder 3, a movable bottom wall 4, and a pressing head 5 as main members.

The container body 2 has a cylindrical body with a lower end opening formed by extending a top wall from an upper end edge of a cylindrical peripheral wall having the same inner diameter from top to bottom. A cylindrical mouth-and-neck portion 7 is provided upright above the periphery of the provided circular window hole. A ridge 8 is provided around the outer periphery of the mouth and neck 7, and the ridge 8 is provided with a notch 9 for venting air.

The cylinder 3 has a bottomed cylindrical shape and has an outward flange extending from the upper end edge of the cylindrical wall. The outward flange is attached to the upper surface of the mouth and neck portion 7 of the container 2 via a packing 10. While being placed, the lower end is fixed to the container body 2 by the locking member 6 in a state of hanging down on the upper part in the body of the container body.

The locking member 6 has a top wall extending from an upper end edge of a peripheral wall fitted on the outer periphery of a large number of plate-like ribs 11 projecting radially on the top wall of the container body, and a back surface of the top wall. A fitting tube 12 fitted to the outer periphery of the mouth and neck portion 7 is provided vertically from the center. A ridge 13 is provided around the fitting cylinder 12, and the ridge 13 is engaged with the ridge 8 of the mouth and neck from above. Further, a short cylinder is suspended from the peripheral edge of the circular window hole formed at the center of the top wall, and the outward flange of the cylinder 3 is fitted between the outer surface of the short cylinder and the upper inner surface of the fitting cylinder 12. In addition, a cylindrical guide tube 14 is provided upright above the periphery of the through hole on the top wall upper surface.

The movable bottom wall 4 closes the lower end opening of the container body by fitting the outer peripheral edge thereof to the lower end of the inner surface of the container body peripheral wall so as to be liquid-tight and ascendable.

The push-down head 5 has a top wall extending from an upper end of a cylindrical peripheral wall fitted to the outer periphery of the guide cylinder 14 of the locking member 6 so as to be able to move up and down and not to come out. A bottomed suction tube 15 is suspended vertically so that it can move up and down.
And a nozzle hole 16 protruding from the upper end of the front end. Further, the coil spring 20 interposed between the rear surface of the top wall and the upper surface of the locking member top wall constantly urges the coil member upward.

A circular suction valve hole is formed in the center of the bottom wall of the cylinder 3 and a plate-shaped suction valve body is provided in which the upper surface of the valve hole is closed so as to be openable and closable. The suction valve 21 is formed.

Further, a hollow portion is formed in the cylinder wall of the suction cylinder 15 in a circumferential band shape, and a piston fitting hole narrower than the hollow portion in a circumferential band shape communicating with the hollow portion and the outside of the cylinder wall. In addition, a through-hole having a front circular shape communicating with the hollow portion and the inside of the cylindrical wall is formed, and a discharge valve hole 22 is formed by the through-hole, the hollow portion, and the piston fitting hole. Further, an annular piston 23 having an H-shaped cross section is fitted on the inner periphery of the cylinder 3 so as to be slidable up and down in a liquid-tight manner and slidable up and down. The upper lower sliding portion of the piston 23 is fitted to the upper portion so as to be vertically movable, and the lower sliding portion of the piston 23 is fitted to the lower portion of the hollow portion when the head 5 rises, thereby closing the piston fitting hole, and thus the discharge valve hole. 22 is configured to be closed, and when the head 5 is pushed down, the piston fitting hole is opened by being pushed upward by the liquid pressure sealed in the cylinder 3, and thus the discharge valve hole 22 is opened. doing. The discharge valve hole 22 and the piston 23
Thus, the discharge valve 24 is formed.

In the figure, reference numeral 25 denotes a cap which covers the head 5 and is detachably attached to the container body, and reference numeral 26 denotes a bottom cap which is fitted and fixed to the lower end of the container body.
All of the above members are made of synthetic resin. Furthermore,
In the above embodiment, the notch 9 for venting the air is provided in the ridge 8 of the neck 7 of the container body, but the ridge 13 of the fitting tube 12 of the locking member 6 is cut as shown in FIG. The notch 9 may be provided, and further, the notch 9 may be provided on each of the ridges 8 and 13.

In the container 1 constructed as described above, when the cap 25 is removed from the state shown in FIG. 1 and the head 5 is pushed down, the suction valve 21 is closed by the liquid pressure of the cream in the cylinder 3, while Due to the hydraulic pressure, the annular piston 23 rises relatively to the suction cylinder 15, the lower part thereof is disengaged and the discharge valve 24 opens, and the cream-like substance in the cylinder 3 is discharged.
From the nozzle hole 16 through the suction tube 15.

Next, when the pressing of the head 5 is released, the head 5 rises due to the resiliency of the spring 20, so that the pressure in the cylinder 3 is negative, the discharge valve 24 is closed, and the suction valve 21 is closed.
Is opened and the cream in the container 2 is sucked into the cylinder 3. At this time, the movable bottom wall 4 rises as the cream-like material decreases.
