The base cap 53 is attached to the mouth of the container 51 and holds the above-described pump suspended from the container 51 . As a mechanism for attaching the base cap 53 to the mouth of the container 51, a male threaded portion may be provided on the outer peripheral surface of the mouth portion of the container 51 and a female threaded portion may be provided on the inner peripheral surface of the base cap 53. It may be engaged by cutting. The base cap 53 of this embodiment includes a tubular neck portion 55 extending upward along the axis O, as shown in FIGS.

The pump is composed of cylinders, pistons, check valves, springs, stems, etc. (not shown). The stem is hollow and located inside neck 55 and is biased upwardly by a spring. A nozzle head 54 is attached to the upper end of the stem. In a pump having such a structure, when the stem is vertically moved, the piston moves within the cylinder, and the content contained in the container 51 is sucked into the cylinder, further pressurized, and flows inside the stem.

The nozzle head 54 is biased upward by a spring through the stem in a state of being connected to the stem. When the nozzle head 54 is urged upward, the neck portion 55 is exposed between the base cap 53 and the nozzle head 54, as shown in FIGS. The nozzle head 54 has an internal passage leading to the inside of the stem leading to a nozzle 54a projecting radially outwardly from the nozzle head 54. As shown in FIG. Therefore, when the nozzle head 54 is pushed down to drive the pump, the contents contained in the container 51 pass through the inside of the stem and the internal passage of the nozzle head 54, and then are discharged from the tip of the nozzle 54a to the outside world. Further, the nozzle head 54 of this embodiment has a flange portion 54b projecting radially outward from its upper portion.
