Abstract: The present invention relates to a vacuum container quantitative release and the scraper formed by a vacuum container, sealing cap, pressure release device, vacuum pump, universal valve, brake and discharge area, where: the vacuum container comes in cylindrical form, having the upper opening a sealing cap, in the lower part of which a sealing unit of small diameter, being the sealing unit concealed at the opening of the vacuum container and having the upper part of the sealing cap a cavity for housing and the center part having a roughly stair-type through-hole, available the housing space for housing the pressure release device of roughly "T" shape which, by turning open the pressure release device, fills stuff into said vacuum container for airtight effect; having said vacuum container inner, intermediate and outer tubes coupled one another inside, where, the outer tube circulates driven by the gear engaged under it and the outer surface having a thread which when the outer tube drives the stuff up driven by the thread to the opening, disposed at a proper position on top of the outer tube and the stuff introduced into the inner tube for temporary housing, having the outer tube by the opening outer cavity a first guide channel in an upward curve and a circulating sealing cap in the shape of "T" and the outer edge of said cap a recessed second guide channel in recessed curve, for the circulating sealing cap and the outer tube in simultaneous turn up, down and having tapering degrees beneath for easy access to the tube for airtight and another cap on top of the circulator sealing cap being fixed with the vacuum container by means of a plurality of supporting rods and housing chute inside the cap for housing a guide pin having the top and lower end engaged into the first, second guide channels for shift up, down in said housed chute, another housing groove on top of the cap, for housing the sealing cap, and having the sealing cap slide vertically inside; said intermediate tube disposed inside the outer tube and sliding vertically inside said outer tube which is secured and coupled inside the intermediate tube, having the lower outer edge the inner tube an outer thread and regulation screw in the lower part of the intermediate tube having the intermediate tube slide vertically by means of the regulation screw for regulation of size of the top opening; the discharge area disposed at the end of the inner tube in the lower part, having the lower part in connection with the inner tube, having the left side closed and the right one open, with a solid control valve inside the discharge area, with a control handle on the right side of the control valve, having the handle in the lower part a back spring, which has a tilt discharge guide hole in the middle, with a first ring teeth rack on the right side, matching the discharge opening and the inner tube with a scraper, having a loop on the top and the bottom, with a plurality of scrapers disposed between the two loops at even intervals, having on the lower loop the scraper 2 annular teeth racks, being the first and the second annular racks crossing each other and when discharging, by driving the control handle, the scrapers scrap the residual substance from the tube wall; the universal valve having a plurality of plungers, in connection with the vacuum pump and the inner tube for suction and by pushing the right button leftward, the vacuum pump and the vacuum container on for extraction of vacuum and the rightmost plunger having a chamber in connection with the vacuum container for extraction of the chamber and reset the plunger when the vacuum pump connects the chamber beneath the brake for extraction of vacuum, while the superior piston moves downward; by means of the linked gears and the motor, the gearing drives the outer tube and the inner tube having the vacuum inside be extracted, the stuff going up and entering into the inner tube through the opening that opens and the vacuum pump extracts the vacuum container.
