Description

The present invention relates to a pump dispenser that discharges a liquid contained in a container body and a discharge container having the pump dispenser.

Conventionally, a discharge container having a pump dispenser that is attached to a container body containing a liquid such as a shampoo liquid, a rinse liquid, and a cosmetic liquid and sucks up and discharges the liquid is known.
However, pump dispensers generally have a liquid discharge rate when the pump head is pushed down by a full stroke, even if it is preset, except when the pump head is pushed down by a full stroke, that is, a liquid based on the degree of pushing down. The discharge amount is not set in advance. Therefore, for example, in a rotation operation other than the full stroke, it is not possible to adjust the discharge amount of the discharged liquid, much less to measure the discharged liquid.

In response to this, the amount of liquid contained in the container body can be adjusted by attaching an adjustment ring to the outer peripheral surface of the cap attached to the mouth of the container body to regulate the amount of pushing down of the pump head. Discharge containers are disclosed (see, for example, Patent Document 1).
