It has become. The lever receiving portion 4 is formed at the rear of the container body 1 facing the front from which the content liquid L is poured out from a nozzle cylinder 36 described later when the pump is used (see FIG. 2).

  In the first embodiment, the lever member 11 is detachably attached to the lever receiving portion 4, and the lever base portion 11 a can be attached to the bearing portion 5 protruding from the left and right side surfaces of the lever receiving portion 4. The lever member 11 is mounted so as to fit behind the lever receiving portion 4 as shown by a one-dot broken line in FIG. 1 during distribution such as storage, transportation, or display. When the pump is used, the lever member 11 is mounted. Is temporarily removed from the lever receiving portion 4, and the lever base portion 11 a is attached to the bearing portion 5 so that the bottom surface of the lever member 11 is placed on the nozzle head 31 as indicated by the solid line in FIG. 1. As described above, the lever receiving portion 4 is pivotally supported by the separate lever member 11. A protrusion 12 projects from the bottom surface of the lever member 11.

  The assembled cap 21 has a cylindrical shape with an opening 23 formed in the top wall 22. Above the assembled cap 21, a ring member 23a fitted to a cylinder upper end portion of a pump 41 described later is disposed. A screw groove is formed on the inner peripheral surface of the ring member 23a. A thread groove is formed in the inner peripheral surface of the side peripheral wall 24, and when the assembled cap 21 is screwed and assembled to the mouth tube portion 2 of the container body 1, as shown in FIG. Further, the outer flange-like flange portion of the cylinder of the pump 41 is sandwiched between the top wall 22 of the assembled cap 21 and the upper end surface of the mouth tube portion 2 of the container main body 1 through packing, whereby the pump 41 is 1 can be firmly assembled and fixed. In this manner, the ring member 23a and the cylinder of the pump 41 are fitted, and the assembled cap 21 is provided between the ring member 23a and the cylinder, so that the assembled cap 21 can freely rotate 360 degrees. The assembled cap 21 and the ring member 23a may have an integral structure.

  The nozzle head 31 has a cylindrical shape with a top and extends a nozzle cylinder 36 laterally (frontward) from the end of the side wall 33, and a fitting cylinder 34 that is suspended from the top 32 has a stem 42 of the pump 41. It fits on the outside of the upper end and is fixed with a set. A thread 35 is formed on the outer peripheral surface of the fitting cylinder 34 so as to be screwed into a thread groove on the inner peripheral surface of the ring member 23a.

  The pump 41 is configured such that the stem 42 and the piston are slidable in a state where the stem 42 is fitted to a piston urged upward by a spring in a vertically long cylindrical cylinder.

  The dispensing container with a pump according to the present embodiment has a thread 35 on the outer peripheral surface of the fitting tube 34 in a state where the nozzle head 31 is displaced downward during distribution such as storage, transportation or display of the product filled with the content liquid L. Is fixed to the threaded groove on the inner peripheral surface of the ring member 23a by screwing so that the content liquid L is not poured out by an erroneous operation. As shown in FIG. 2, when the dispensing container with a pump is used, the nozzle head 31 fixed between the 1 o'clock direction and the 2 o'clock direction of the clock is turned counterclockwise to change the screwing state. When this occurs, the nozzle head 31 is displaced upward by the upward biasing action of the spring disposed in the pump 41 (the state shown in FIG. 1), and the content liquid L is discharged by pushing the nozzle head 31 down from this state. It becomes possible to dispense.
