[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for dispensing cream.

[0002]

[Prior art]

Heretofore, as a container for dispensing creamy material, a container body having a top wall extending from the upper edge of the peripheral wall, a lower surface of the container body being hermetically closed and slid upward. A movable bottom wall that is freely fitted and a suction valve and a discharge valve are provided in a flow path from a through hole formed in the top wall of the container body to a nozzle hole, and the container is formed by utilizing the pressure of an elastic dome. There is known a pump device configured to discharge a creamy substance in the body.

[0003] In this type of conventional container, after the contents are poured out,
There is a case where a problem occurs in that the content drips from the nozzle tip and stains the periphery.

The present invention solves the above-mentioned disadvantages of the prior art,
It is an object of the present invention to propose a cream-like material discharging container in which the contents do not leak from a nozzle after the contents are discharged.

[0005]

According to the present invention, in order to solve the above-mentioned problems, a top wall 7 is extended from an upper edge of a peripheral wall 6 and a cylinder 8 is provided above the center of the upper surface of the top wall 7 in order to solve the above problems. , A movable bottom wall 3 in which the lower surface of the container body 2 is hermetically closed and slidably fitted upward, and a top wall of the container body 7 Capacity adjusting rod 4 that stands up from the center of the upper surface into the cylinder 8
And mounted vertically movably on the top surface of the container body top wall 7 in an upwardly biased state.
And a push-down head 5 with a nozzle which hangs up and down on the inner surface of the cylinder 15 and slidably fits an inner peripheral edge of an inward flange 16 extending from a lower end of the cylinder 15 to an outer periphery of the capacity adjusting rod 4. The container body top wall 7 is provided with a suction valve hole 9 communicating with the inside of the cylinder 8, and an elastic plate-shaped suction valve body 10 is provided to open and close the upper surface of the valve hole 9, thereby forming the suction valve 11. A discharge valve hole 21 is provided in the cylinder wall of the suction cylinder 15, and an annular piston 22 having an H-shaped cross section, whose outer peripheral surface is liquid-tightly fitted to the inner periphery of the cylinder 8, is pushed down by pushing down the head 5. The discharge valve hole 21 was opened and mounted so as to be able to move up and down so that the discharge valve hole 21 was closed when the head 5 was lifted up.

[0006]

When the head 5 is pushed down from the state shown in FIG. 1, the suction valve 11 is closed by the hydraulic pressure of the cream in the cylinder 8, while the annular piston 22 is pulled up by the hydraulic pressure.
It rises relatively to 15 and the lower part is disengaged and the discharge valve
23 is opened, and the creamy substance in the cylinder 8 is discharged from the nozzle hole 17 through the suction valve 15 from the discharge valve 23.

Next, when the pressing of the head 5 is released, the head 5 rises due to the resilience of the spring 14, so that the pressure in the cylinder 8 becomes negative and the discharge valve 23 closes, and the suction valve 11 opens as shown in FIG. As a result, the cream in the container 2 is sucked into the cylinder 8. At this time, the movable wall 3 rises as the cream-like material decreases.

On the other hand, in the suction cylinder 15, the capacity adjusting rod 4 is relatively lowered with respect to the suction cylinder 15 with the rise of the head 5, so that the internal capacity is slightly increased, and the negative pressure As a result, the cream-like substance that fills the inside of the suction tube 15 from the nozzle tip is slightly drawn into the interior, and as a result, liquid dripping from the nozzle tip does not occur.

[0009]

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

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

The container 2 has a cylindrical shape with a lower end opening formed by extending the top wall 7 from the upper end edge of the peripheral wall 6, and the inner diameter of the peripheral wall is the same from top to bottom. A cylindrical cylinder 8 having an upper end opened upward from the center of the upper surface of the top wall 7 is provided upright.

The movable bottom wall 3 is fitted to the lower end of the inner peripheral wall 6 of the container body so that the outer peripheral edge thereof is liquid-tight and slidably ascendable.
The opening at the lower end face is closed.

The capacity adjusting rod 4 is cylindrical and has a container top wall 7.
It is integrally erected upward from the center of the upper surface inside the cylinder 8. A suction valve hole 9 is formed outside the adjusting rod 4. Further, a plate-shaped suction valve body 10 having elasticity extending outward from the lower end edge of the fitting cylindrical portion fitted to the lower end of the outer surface of the capacity adjusting rod 4 is provided. The suction valve hole 9 and the suction valve body 10 constitute a suction valve 11.

The push-down head 5 is mounted by fitting the lower end of the peripheral wall 12 into a fitting groove 13 provided on the outer peripheral edge of the upper surface of the container body so as to be vertically movable and unable to come out. A coil spring 14 is interposed between the coil spring and the rear surface to constantly urge the coil spring 14 upward. A suction tube 15 is suspended vertically from the center of the rear surface of the top wall into the cylinder 8, and an inner peripheral edge of an inward flange 16 extending from a lower end of the suction tube 15 is attached to the capacity adjusting rod 4. The upper end of the head 5 is communicated with a nozzle hole 17 opened at the front and rear upper ends thereof.

Further, a hollow portion 18 is formed in the cylindrical wall of the suction cylinder 15 in a circumferential band shape, and a piston fitting narrower than the hollow portion 18 in a circumferential band communicating with the hollow portion 18 and the outside of the cylindrical wall. Hole
19, and a through hole 20 having a circular front face communicating with the hollow portion 18 and the inside of the cylindrical wall is formed.
And the piston fitting hole 19 form a discharge valve hole 21.

Further, an annular piston 22 having an H-shaped cross section is fitted on the inner periphery of the cylinder 8 so that outer vertical sliding portions 22a and 22b are fitted in a liquid-tight and vertically slidable manner. The moving part 22c is fitted to the upper part of the hollow part 18 so as to be vertically movable, and the inner lower sliding part 22d of the piston 22 is
When the head 5 is pushed down, the piston fitting hole 19 is closed and the discharge valve hole 21 is closed by fitting into the lower part of the hollow portion 18, and when the head 5 is pushed down, it is sealed in the cylinder 8. The piston fitting hole 19 is opened by being pushed upward by the hydraulic pressure, and the discharge valve hole 21 is opened. The discharge valve hole 21 and the piston 22 form a discharge valve 23.
