Abstract: Provided is a cosmetic container containing an antimicrobial impregnating material made of a polycaprolactone polyol foam in an antimicrobial sealed container, and more particularly, an antimicrobial cosmetic container containing an antimicrobial material which may reinforce disadvantages of polyester polyol foam- and polyether polyol foam-type impregnating materials, such as water resistance (hydrolysis resistance) and oil resistance and inhibit the proliferation of microorganisms.

Abstract: The present invention relates to a coupler, in which a guard cap coupled to a high-frequency heat-sealed cap member is additionally provided at both ends of the body member to prevent the collator and the tube from separating from the body member and cut off foreign matter from flowing into the body member, and the color of the guard cap is made different to make it easy to identify from outside the contents flowing in the tube. The coupler comprises a coupling member 200 and 200a having a plurality of guide protrusions 210 and 210a that are formed at predetermined lengths and regularly spaced intervals and extended along the outer rim of a cap member 12 and stop protuberance 220 that is bent-formed at one end portion of the guide protrusions 210 and 210a; and a guard cap 100 that is coupled to said coupling member 200 and 200a so as to prevent the collator 30 and the tube 20 from being separated from the body member 11 by external force and foreign matter from infiltrating into said tube 20 from outside.

Abstract: A device for locking a cap nut for a coupling includes a hooking plate 100 extended out of the body 50 connected to the metallic connecting pipe 21, a plurality of hooking protrusions 110 protruded from the hooking plate 100 at a regular space, and a plurality of hooking grooves 200 formed at a position facing the hooking protrusion 110 and engaged with the hooking protrusion 110 to prevent the cap nut 40 from being released when screwing the cap nut 40, so as to prevent the cap nut 40 from being released, so eventually securely assembling the connecting pipes 21 not to be separated from the coupling 10.
