Abstract
Provided is an airless compact container. The airless compact container blocks air from flowing into a refill container through a pumping member and thus prevents contents from being corrupted by inserting the refill container provided with the pumping member into one side of a middle case and then allowing contents to be discharged to the upper surface of a content outlet part through the pumping operation of the pumping member when a user pressurizes the lower end portion of the refill container.
Claims9
A dispenser container, the dispenser container comprising:
- a container body for storing contents;
- a pumping member coupled to an upper portion of the container body and discharging the contents stored in the container body to the outside through pumping operation;
- and
- a button member, disposed at an upper portion of the pumping member, delivering pressure according to user's manipulation of the pumping member and causing pumping operation, further forming a discharging hole where contents are discharged,
- wherein the pumping member includes:
- a pump housing coupled to an upper portion of the container body and forming a cylinder at a center portion thereof;
- a piston rod, an upper portion of which is coupled to an inner side of the button member and a lower portion of which is disposed at an inner side of the cylinder and moves along with an ascent/descent of the button member, further consisting of a content movement passage at an inner side thereof such that contents can move, and a content movement hole at a lower portion thereof such that contents can move to the content movement passage;
- a seal cap, made of soft material, encasing the piston rod and moving along an inner wall of the cylinder when the button member ascends/descends and thereby changing inner pressure of the cylinder, further consisting of an opening/closing tip so as to be separated with a small gap from an outer circumferential surface of the piston rod when the piston rod descends according to pressurization of the button member and thereby to open a content movement hole;
- and
- an elastic body providing an elastic force such that the button member can move to an upward direction.

- and
- an elastic body providing an elastic force for moving the button member to an upward direction,
- wherein a content movement passage is provided between the seal cap and the piston rod such that contents having moved into the cylinder can move to a discharging hole when the button member is pressurized.
