Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a creamy substance dispensing container.

[0002]

[Prior Art] [Problems to be solved by the device]

 Conventionally, as a creamy substance pouring container, a container body having a top wall extending from an upper edge of a peripheral wall and an underside of the container body are hermetically closed and slidable upward. A suction valve and a discharge valve are provided in the moving bottom wall and the passage extending from the through hole formed in the top wall of the container to the nozzle hole, and the pressure of the elastic dome is used to discharge the creamy substance in the container. A pump device having such a structure is known.

In the conventional container of this type, after pouring out the content, there is a possibility that the content drips from the tip of the nozzle and stains the surrounding area.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art and to propose a creamy substance dispensing container in which the contents do not leak from the nozzle after the contents have been dispensed. .

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the creamy substance dispensing container of the present invention has a lower end surface opening formed by extending a top wall 7 from an upper edge of a peripheral wall 6 and a cylinder 8 standing above the center of the top surface of the top wall 7. Container body 2, a movable bottom wall 3 in which the lower surface of the container body 2 is airtightly closed and is fitted so as to be slidable upward, and the inside of the cylinder 8 from the center of the upper surface of the container body top wall 7 The volume adjusting rod 4 which is erected upright is mounted on the upper surface of the top wall 7 of the container body so as to be vertically movable, and the suction cylinder 15 is vertically hung in the cylinder 8 so as to be vertically movable. There is a downward pressing head 5 with a nozzle in which an inner peripheral edge of an inward flange 16 extending from the lower end of the cylinder 15 is slidably fitted to the outer periphery of the capacity adjusting rod 4, and a cylinder is provided on the top wall 7 of the container body. 8 is provided with a suction valve hole 9 that communicates with the inside of the valve 8. A suction valve body 10 in the form of an elastic plate that closes the open / close state is provided, and thus a suction valve 11 is configured, and a discharge valve hole 21 is provided in the cylinder wall of the suction cylinder 15, and the inside of the cylinder 8 is The discharge valve hole 21 is opened when the head 5 is pushed down and the discharge valve hole 21 is closed when the head 5 is lifted up. As described above, the discharge valve 23 is mounted so as to be movable up and down.

[0006]

[Action]

 When the head 5 is pushed down from the state of FIG. 1, the suction valve 11 is closed by the hydraulic pressure of the creamy substance in the cylinder 8, while the annular piston 22 is raised by the hydraulic pressure relative to the suction cylinder 15. The lower part is disengaged to open the discharge valve 23, and the creamy substance in the cylinder 8 is discharged from the discharge valve 23 through the suction cylinder 15 through the nozzle hole 17.

Next, when the pressing of the head 5 is released, the head 5 rises due to the elastic force of the spring 14, so that the inside of the cylinder 8 becomes negative pressure and the discharge valve 23 closes. As shown in FIG. Is opened and the creamy substance in the container body 2 is sucked up into the cylinder 8. At this time, the movable wall 3 rises as the creamy substance decreases.

On the other hand, in the suction cylinder 15, as the head 5 rises, the capacity adjusting rod 4 descends relatively to the suction cylinder 15, so that its internal capacity increases slightly. Since a negative pressure is generated, the creamy substance filling the suction cylinder 15 from the tip of the nozzle is drawn into the inside a little, and as a result, the liquid does not drip from the tip of the nozzle.

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 closes the opening of the lower end surface of the container body 2 by fitting the outer peripheral edge to the inner peripheral lower end of the container body peripheral wall 6 so as to be liquid-tight and capable of sliding up.

The capacity adjusting rod 4 has a cylindrical shape, and is integrally provided upright from the center of the upper surface of the top wall 7 of the container body to above the inside of 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 like a flange outwardly extends 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. The suction valve hole 9 and the suction valve body 10 constitute a suction valve 11.

The push-down head 5 is mounted such that the lower end of the peripheral wall 12 is fitted in 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 cannot be pulled out, and the upper surface of the container body 2 and the head 5 are fitted. A coil spring 14 is interposed between the back surface of the top wall and the back surface of the top wall to constantly urge it upward. A suction tube 15 is vertically movably suspended in the cylinder 8 from the center of the back surface of the top wall, and the inner peripheral edge of an inward flange 16 extending from the lower end of the suction tube 15 is connected to the capacity adjusting rod 4 The outer peripheral surface of the head 5 is fitted in a liquid-tight manner and is slidable in the vertical direction.

In addition, a hollow portion 18 is formed in a circumferential band shape inside the cylinder wall of the suction cylinder 15, and a piston fitting narrower than the hollow portion 18 is formed in a circumferential band shape communicating with the hollow portion 18 and the outside of the cylinder wall. Forming a joint hole 19, and further forming a through hole 20 having a front circular shape that communicates with the hollow portion 18 and the inside of the cylinder wall, and discharge through the through hole 20, the hollow portion 18, and the piston fitting hole 19. A valve hole 21 is formed.

Further, an annular piston 22 having an H-shaped cross section, in which outer vertical sliding portions 22a and 22b are fitted so as to be liquid-tight and vertically slidable, is provided on the inner circumference of the cylinder 8, and an inner upper sliding portion of the piston 22 is provided. The moving part 22c is fitted in the upper part of the hollow part 18 so as to be movable up and down, and the inner lower sliding part 22d of the piston 22 is fitted in the lower part of the hollow part 18 when the head 5 rises to fit the piston. The fitting hole 19 is closed, and the discharge valve hole 21 is closed, and when the head 5 is pushed down, the piston 5 is pushed up by the hydraulic pressure sealed in the cylinder 8 to form the piston fitting hole 19 described above. The discharge valve hole 21 is formed by opening. The discharge valve hole 21 and the piston 22 form a discharge valve 23.
