Description of the Related Art Generally, most of liquid shampoos, rinses, and the like used in shower rooms and bathrooms are housed in containers provided with a liquid ejection pump. The liquid ejection pump in this case is generally a vertical reciprocating pump having a press-down nozzle head, which is attached to the mouth and neck of the container body by a mounting cylinder provided at the upper part of the cylinder, and is provided with the press-down nozzle head. The pumping action is generated by the push-down operation and the return rise by the built-in spring, and the liquid in the container is sent out from the push-down nozzle head to the outside. The depression nozzle head is mounted on a stem that projects upwardly from the cylinder through a retaining ring mounted on the top of the cylinder, which stem transmits mechanical movement and supplies liquid from the depression nozzle head. However, usually, a slight gap is formed between the stem and the retaining ring, and it is considered that outside air is introduced into the head space of the container through the gap. Therefore, even if the liquid decreases in the container, the pressure does not become negative. On the other hand,
A screwing means is provided between the press-down nozzle head and the holding ring to screwly support the press-down nozzle head at the lower limit. This screw closes the gap and prevents the pump from being deflected. , Prevention of liquid leakage at the product distribution stage, etc.
Damage prevention, length reduction, etc. have been obtained.
