Abstract:
1. An airtight cosmetic container, comprising: a container body; an inner container installed in the container body and containing a cosmetic material therein; an inner cover rotatably and openably combined with a side of the inner container and having a sealing rib that comes into close contact with an upper end surface of the inner container by a pressing force of a pressure protrusion; and an outer lid combined with a side recess of the container body by a hinge bracket and having a locking protrusion at a portion opposed to the hinge bracket so as to be locked to a locking step of a locking hole of a push button mounted to the container body at a portion opposed to the side recess, so, when the outer lid is closed, the outer lid brings the sealing rib into close contact with the inner container by pressing a pressure protrusion of the inner cover, and when the push button is pushed so as to release the locking protrusion, the outer lid is opened; wherein the inner container includes a cosmetic tray, and a packing case in which the cosmetic tray is installed and a hinge bracket is provided so as to be combined with a hinge bracket of the inner cover; wherein the packing case includes inner and outer elastic sidewalls that form a seal groove therebetween, so the sealing rib of the inner cover is inserted into the seal groove, with inner and outer curved protrusions protruding toward each other on opposed surfaces of the inner and outer elastic sidewalls so as to come into elastic close contact with inner and outer circumferential surfaces of the sealing rib inserted in the seal groove, thereby realizing an airtight sealing effect; wherein the container body includes a lower case to which the push button is mounted, and an outer support case that is seated in a seat of the lower case and has a through hole through which the locking protrusion of the outer lid passes; wherein the packing case is seated in the seat of the lower case in such a way that the outer elastic sidewall of the packing case is fitted and held in an inner circumferential surface of the outer support case, and the inner elastic sidewall of the packing case is held by an outer circumferential surface of an inner support case that is fitted over an outer circumferential surface of the cosmetic tray; and wherein, to allow the inner and outer elastic sidewalls to be opened, the packing case is assembled with the inner and outer support cases in such a way that a predetermined gap is defined between inner and outer circumferential surfaces of the inner and outer elastic sidewalls and inner and outer circumferential surfaces of the inner and outer support cases.
