Title:
PUMP CONTAINER HAVING RESIDUAL AMOUNT PREVENTION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2022/114445
Kind Code:
A1
Abstract:
A pump container having a residual amount prevention function of the present invention is configured such that, when a pump piston is vertically lowered by a pressing force of a pump head, a lower-side pump body and a tube of the pump body stop without rotation regardless of a rotational force by which a rotation ring engaged with a spiral groove formed on the outer circumferential surface of the pump piston rotates in one direction, and when the pump piston is raised, the lower-side pump body and the tube are rotated by receiving the rotational force which is for rotation of the rotation ring in the opposite direction due to the engagement between the spiral groove of the pump piston and a spiral projection or a connecting projection of the rotation, such that the residual amount of a solution in a container body can easily be used completely. As such, it is possible to remove unnecessary time and effort for inverting or separating the container pump, and reduce environmental pollution by preventing waste of a solution that is not used and discarded.
