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.

First claim

What is claimed is:

1. An airless compact container comprising:
a lower case comprising a button part coupled thereto for opening/closing of an upper case;
a middle case coupled to the lower case and comprising a content outlet part having a content outlet hole formed therein and a container receiving part formed at one side thereof to allow a refill container to be inserted into and withdrawn from the container receiving part;
a refill container storing contents, inserted into and withdrawn from the container receiving part, and comprising a pumping member integrally formed on an upper portion thereof and discharging stored contents by an pumping operation;
a nozzle part moving contents discharged through the pumping member to the content outlet hole; and
an upper case coupled to the middle case by a hinge and opened in accordance with an operation of the button part,
wherein when a lower end portion of the refill container is pressurized, the refill container moves forward in the container receiving part, and thus the pumping operation of the pumping member is performed to allow contents to be discharged to the content outlet part,
wherein the upper case comprises a limitation protrusion formed on an inner side of the upper case and limiting the pumping operation of the pumping member by supporting the upper portion of the refill container when the upper case is closed and thus preventing the refill container from moving, and
wherein the container receiving part has a protrusion insertion groove formed therein such that the limitation protrusion is inserted into the protrusion insertion groove when the upper case pivots and closes.

2. The airless compact container of claim 1 , wherein the middle case comprises a nozzle fixing protrusion formed on a central portion of the undersurface of the middle case and downwardly extending so as to fix the nozzle part.

3. The airless compact container of claim 2 , wherein the nozzle part comprises:
a nozzle having a tubular shape and forming a movement passage of contents discharged through the pumping member; and
a coupling protrusion coupled to the nozzle fixing protrusion by press-fitting at the end of the nozzle and comprising a lower end portion thereof closed such that contents moving through the nozzle upwardly moves to the content outlet hole.

4. The airless compact container of claim 1 , wherein the container receiving part comprises a pump fixing protrusion formed therein, coupled to an upper portion of the pumping member to fix the pumping member, and communicating with the nozzle part such that contents discharged through the pumping member move to the nozzle part.

5. The airless compact container of claim 1 , wherein the lower case and the middle case have a lower support groove and an upper support groove so as to support the nozzle part at a lower portion and an upper portion thereof, respectively.
