The fixed cylinder 11 may have an outward flange attached to the upper end engaged with the upper surface of the fitting cylinder 7, and the suction valve 12 may be a known valve conventionally used in this type of container, such as one using a ball valve. In the illustrated example, a single or a plurality of small through holes 15 are bored in the middle of the inward and outward flanges 13 at equal intervals, and the upper surfaces of the small through holes are watertightly closed to form a flange on the upper surface of the inward flange 13. Elastic sheet 16
And the inward end of the elastic sheet is attached to the inward flange and the guide punch 14 above the flange.
It is sandwiched between and. The nipping is performed by inserting a protrusion previously provided with a gap from the inward flange into the gap and inserting the inner end of the elastic sheet into the gap, and then forcibly pushing down and deforming the protrusion. Can be done. It should be noted that the clamping can be performed by providing a protrusion on the fixed cylinder 11 side and using the protrusion. Further, the elastic sheet does not have to have a brim shape, and may be placed on a part of the upper surface of the inward flange.

In the illustrated example, the lower part of the guide pestle 14 is formed by a tubular portion having an opening on the lower surface, a rod portion is erected from the upper end of the tubular portion, and a ridge 18 is provided in the middle of the rod portion. On the outer surface of the half rod portion, a plurality of grooves as flow paths are provided vertically.

Reference numeral 20 denotes an elastically deformable member, which guides a small-diameter cylinder 23 from a lower-end cylindrical portion 21 fitted in the gap between the fitting cylinder 7 and the guide cylinder 8 described above through an elastic cylindrical portion 22 having an upper small diameter. Standing up above the pestle 14, the upper end surface of the small diameter cylinder is closed by a top plate 25 with a slit 24 in which the cut surfaces elastically contact each other in an airtight manner.

In the illustrated example, the elastic tube portion is formed as a bellows tube. An inward flange 26 is attached to the upper end of the bellows-like elastic tubular portion 22 so that the upper edge of the inner peripheral portion of the inward flange is engaged with the lower surface of the protrusion 18 of the guide punch 14. The top plate 25 with the slit 24 is preferably formed by fitting a rubber-made cap member separately provided as shown in the figure to the upper end of the small-diameter cylinder 23. By doing so, opening and closing of the slit is ensured. You can A sufficient gap is provided between the top plate 25 and the upper end of the guide punch 14 to compress the pressure chamber 27 formed by the space between the guide member 10 and the elastically deformable member 20, that is, by pressing down the elastically deformable member. The pressure chamber should be provided so that it can be compressed.
When pushed down to the lower limit, the upper end of the guide punch 14 opens the slit 24.

Reference numeral 30 denotes a head, which is a small-diameter cylinder of the elastically deformable member described above.

In order to prevent misalignment of the small-diameter cylinder 23, an engaging ridge is provided on the outer surface of the lower end of the small cylinder 23, and the lower end of the inner cylinder 31 is placed on the upper surface of the engaging ridge. And the outer peripheral portion of the upper end of the small diameter cylinder is engaged with the lower surface thereof.

In the above structure, the head is changed from the state shown in FIG.
When 30 is pushed down, the inside of the pressurizing chamber 27 is pressurized, so that the room air is pressurized and opens the slit 24 and is discharged from the nozzle 32. However, as shown in FIG. When the slit 24 is lowered, the upper end of the guide punch 14 forcibly pushes the slit to open and the air in the pressurizing chamber 27 is released from the high pressure state. Next, when the head 30 is released, the small-diameter cylinder 23 rises due to the elastic cylinder part 22 restoring, and the inside of the pressurizing chamber 27 becomes negative pressure because the slit 24 is also closed, so that the suction valve 12 is opened and the container is opened. When the creamy substance in the body is sucked into the pressurizing chamber, the sliding bottom plate 5 rises to eliminate the negative pressure in the container due to the decrease in the creamy substance.

From the next time onward, push down the head 30 with the slit 24
Need not be forced to open, and by moving the head up and down in this way, the slit serves as a discharge valve to pour out the pressurized interior creamy substance from the nozzle 32, and to suck in the creamy substance in the container. Flow into the pressurizing chamber 27 through 12.

FIG. 4 shows a third embodiment. In this embodiment, the lower end of the coil spring 35 provided in the same manner as in the second embodiment is formed in a flange shape and the inward flange 13 is formed.
The elastic sheet (16) placed on the upper surface is pressed against the upper surface of the inner end of the elastic sheet (16) to sandwich the inner end of the elastic sheet between the lower end of the spring and the inner peripheral portion of the inward flange below the spring. Therefore, in this case, unlike the cases of the first and second embodiments, it is not necessary to attach the protrusion 17 for sandwiching the elastic sheet to the lower part of the guide punch 14.

FIG. 5 shows an example in which the elastic tubular portion 22 is formed in a dome shape, and the other portions are the same as in the case of FIG. In each of the above-described embodiments, the coil spring 35 made of metal and the cap-shaped member made of rubber are removed, and the coil springs 35 are made of synthetic resin.
