Abstract
A dispensing container with a pump includes a neck, a manual pump of a push-down type disposed in the neck, a push-down head fitted to the top of the pump, and a cap having an attaching cylinder fitted around the neck. A rotary cylinder is disposed on the outside of the attaching cylinder coaxially on central axis. A cover cylinder having a cover wall is disposed coaxially between the attaching cylinder and the rotary cylinder in a manner capable of going up and down under the condition that an elevating system has been established with the attaching cylinder and the rotary cylinder by the rotary movement of the rotary attachment. The cover cylinder is disposed so the push-down head is exposed out of the cover cylinder at its lower-limit position and cannot be pushed down at the upper-limit position of the cover cylinder to prevent contents from being erroneously discharged.
