PROBLEM TO BE SOLVED: To attach a discharge valve which is usually closed elastically to the end of a nozzle to make the push-down head of a pump type liquid extracting container convenient for extracting high viscosity liquid relatively little by little. SOLUTION: A through hole 14 is formed in the middle of a top plate 13, a stem engagement cylinder 15 is hung down from the periphery of a through hole fringe, a slender recessed part 17 is formed from a through hole rear fringe to a tope plate front fringe through right and left side fringes by erecting the first slender peripheral wall 16 from the top plate, forming a small gap outside the right and left wall parts and the rear wall part of the first peripheral wall, a front wall part with a head main body 12 which erects the second peripheral wall as a common front wall part 16c, into the small clearance, and the first foot plate 23 which is hung from the lower surface of an elastic flat plate 22 is fixed. Moreover, the upper surface of the slender recessed part 17 is formed from an elastic lid plate 21 which is closed by the elastic flat plate 22, a thin wall part 25 is formed at elastic flat plate front end, and a discharge valve 26 is formed by the thin wall part and a common front wall part 16 upper surface. |
