The present invention relates to an eco-pump type cosmetic container, and more particularly, to an eco-pump type cosmetic container having a shoulder portion and a shoulder bush, which are integrally formed and used, thereby preventing the shoulder bush from being separated from the shoulder portion, maximizing a pumping effect so that a space between the shoulder portion and the shoulder bush is completely sealed, and easily opening a seat portion by supporting the upper end of the shoulder bush to be in close contact with the seat portion, which is formed on an elastic member.

1. An eco-pump type cosmetic container, comprising: a container having a liquid cosmetic stored therein;a shoulder portion which is fastened to an upper portion of the container and has a shoulder bush integrally formed at a center of the interior thereof so as to protrude upwards;an elastic member, which is fastened and fixed inside a shoulder portion, is made of a silicone rubber material having an elastic restoration force, and has a sheet at the center thereof so as to be in close contact with a top surface of the shoulder bush; anda pressing portion which is installed and fixed on an upper portion of the elastic member to pressurize the elastic member,wherein the shoulder portion has a guide surface along which the pressing portion is guided and moved, a double engaging projection which is fitted and fixed to a fixing protrusion formed on the pressing portion to be prevented from being separated to the outside, a fitting groove formed so that a connection projection of the container is inserted and fixed therein, a separation preventing protrusion formed on the lower portion of the guide surface so as to prevent the elastic member from being separated upwards, and a discharge hole formed to penetrate from the bottom surface to the upper portion thereof so that the liquid cosmetic, which is stored in the container, is discharged to the outside,wherein the shoulder portion further includes a support portion which is fixed onto an inner surface wherein the support portion is in an annular shape, is in close contact with an outer surface of the elastic member, and supports the elastic member deformed by the pressing portion wherein the support portion deforms as the elastic member deforms. 2. The eco-pump type cosmetic container of claim 1, wherein the shoulder bush includes a cutting portion which is formed so that an upper end is narrowed and a lower end is gradually widened, disposed in close contact with the sheet, and cuts the sheet by the operation of the pressing portion. 3. The eco-pump type cosmetic container of claim 1, wherein the elastic member is formed of 0.2 to 1 part by weight of an antibacterial ceramic composition in which 40 to 80 parts by weight of silicon oxide, 20 to 50 parts by weight of aluminum oxide and 1 to 10 parts by weight of silver are mixed with respect to 100 parts by weight of a silicone resin, and the silicon resin is formed of 40 parts by weight of an ethylene vinyl acetate resin, 19 parts by weight of a polyolefin resin, 18 parts by weight of an ethylene propylene copolymer rubber, 3 parts by weight of bromo butyl rubber, 5 parts by weight of calcium carbonate, 1 part by weight of zinc oxide, 0.65 part by weight of stearic acid, 3 parts by weight of white spindle oil, 1 part by weight of a cross-linking agent, 0.04 part by weight of a vulcanization accelerator and 0.65 part by weight of a blowing agent.
