Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention is used for high-viscosity pumps that pump and supply high-viscosity materials such as grease, putty, sealants, adhesives, and printing inks. The present invention relates to high viscosity material containers.

(Prior art) Publication of Utility Model Publication No. 58-23985 and Publication of Utility Model Publication No. 63-10
No. 16 discloses a high viscosity pump suitable for pumping and supplying high viscosity materials such as grease, putty, sealants, adhesives, and printing inks.

As shown in FIG. 8, the basic structure of this high viscosity pump is that when the pump body 12 is pressurized into a container 13 by a lifting mechanism 11 such as a fluid pressure cylinder installed upright on a base 10, the pump body 12 The inductor plate 14 provided at the bottom allows the high viscosity material in the container 13 to flow into the pump body 1.
The high viscosity material is collected at the opening at the lower end of the pump body 12, is sucked up by the pump mechanism within the pump body which is reciprocated by the pump drive unit 15 provided at the top of the pump body 12, and is discharged from the high viscosity material discharge unit 16. It is something that will be done.

4 inside the container 13, the high viscosity material adhering to the inner wall of the container 13 (which could not be wiped off by the rubber plate +4b when descending) is removed by the outer peripheral edge of the rubber plate +4b that is curved upward. The high viscosity material 17t that is scraped off and accumulates on the upper surface of the inductor plate 14 contaminates the pump, container, operator, etc. when the inductor plate is pulled out.

Furthermore, since the inductor plate 14 has a conical part 14e formed in the center to collect the high-viscosity material, a high-viscosity material 17b having a shape corresponding to the conical part 14e remains at the bottom of the container 13. Waste occurs along with the high viscosity material 171 on the inductor plate 14.

Furthermore, the empty container 13 is disposed of,
