Lip gloss cartridge and refillable lip gloss using same

Abstract

A lip gloss cartridge and a refillable lip gloss using same are disclosed. To this end, the present invention relates to a refillable cartridge comprising: a refill container having an inlet provided above a support rim formed on the outer peripheral surface thereof, and having, at the lower portion thereof, a filling part in which cosmetic contents are filled and which is open toward the inlet; an airtight packing which is airtightly coupled to the inlet of the refill container, and which has a wiper formed in the center of the inside thereof; and a cover that opens/closes with respect to the inlet, wherein one or more idling-prevention ribs are formed in the longitudinal direction on the outer peripheral surface of the filling part at the lower end of the support rim, a blocking rod for airtightly blocking the wiper of the airtight packing during closing of the cover is formed in the cover, and, in a state in which only the cover is removed from a refillable cartridge structure, a cap of a brush rod having an application tip on an application connection rod is coupled to be opened/closed with respect to the inlet of the refill container so as to be used during lip gloss application, or a packaging container is additionally covered and is coupled to the outer side of the filling part of the refill container such that more convenient portable usage is provided.

1 . A lip gloss cartridge, comprising:
 a refill container having an inlet formed above a support rim formed on an outer peripheral surface of the refill container, and a filling portion in which a cosmetic liquid is filled and formed below the support rim so as to be open toward the inlet;   an airtight packing airtightly coupled to the inlet of the refill container and having a wiper formed in a center of an inside of the airtight packing; and   a cover configured to be opened and closed relative to the inlet,   wherein one or more idling prevention ribs are formed in a longitudinal direction on an outer peripheral surface of the filling portion at a lower end of the support rim,   a blocking rod configured to airtightly block the wiper of the airtight packing when the cover is closed is formed inside the cover, and   a reverse rotation prevention protrusion configured to prevent arbitrary reverse rotation is formed on an upper surface of the support rim of the refill container.   
     
     
         2 . A refillable lip gloss applicator, comprising:
 a refill container having an inlet formed above a support rim formed on an outer peripheral surface of the refill container, and a filling portion in which a cosmetic liquid is filled and formed below the support rim so as to be open toward the inlet;   an airtight packing airtightly coupled to the inlet of the refill container and having a wiper formed in a center of an inside of the airtight packing; and   a brush rod comprising a brush rod cap that is configured to be opened and closed relative to the inlet of the refill container, a tip connecting rod extendedly formed at a lower end of an inside of the brush rod cap, and an application tip provided at a lower end of the tip connecting rod,   wherein one or more idling prevention ribs are formed in a longitudinal direction on an outer peripheral surface of the filling portion at a lower end of the support rim, and   a reverse rotation prevention protrusion configured to prevent arbitrary reverse rotation is formed on an upper surface of the support rim of the refill container.   
     
     
         3 . The refillable lip gloss applicator of  claim 2 , further comprising:
 a packaging container configured to be detachably mounted on an outside of the refill container to cover the refill portion of the refill container,   wherein one or more idling prevention grooves into which the idling prevention ribs formed on the outer peripheral surface of the filling portion at the lower end of the support rim are inserted are formed correspondingly on an inner peripheral surface of the packaging container, and   the refill container is prevented from rotating along with the brush rod cap due to mutual fitting engagement of the idling prevention ribs and the idling prevention grooves when the brush rod cap of the brush rod is rotated while holding the packaging container.   
     
     
         4 . The refillable lip gloss applicator of  claim 2 , wherein a locking rim is further formed on the outer peripheral surface of the filling portion of the refill container. 
     
     
         5 . The refillable lip gloss applicator of  claim 4 , wherein a locking groove is further formed on an inner peripheral surface of the packaging container,
 wherein when coupling the packaging container to the filling portion of the refill container, the locking groove is fittedly coupled to the locking rim formed on the outer peripheral surface of the filling portion, thereby preventing the packaging container from being arbitrarily separated from the filling portion.   
     
     
         6 . The refillable lip gloss applicator of  claim 2 , wherein a reverse rotation prevention groove opposite to the reverse rotation prevention protrusion formed on the upper surface of the support rim of the refill container is further formed on an inner peripheral surface of a lower end of the brush rod cap that is configured to be opened and closed relative to the inlet of the refill container,
 wherein when the brush rod cap is completely closed, the reverse rotation prevention groove is fittedly engaged with the reverse rotation prevention protrusion, so the brush rod cap is prevented from being arbitrarily opened unless the brush rod cap is artificially opened.   
     
     
         7 . The refillable lip gloss applicator of  claim 3 , wherein a step configured to support the support rim of the refill container when the packaging container is coupled to the filling portion of the refill container is further formed on an inner peripheral surface of an upper end of the packaging container. 
     
     
         8 . The refillable lip gloss applicator of  claim 5 , wherein an upper portion of the locking groove of the packaging container has an inclined entry surface widened upward to facilitate entry and coupling of the locking rim. 
     
     
         9 . The refillable lip gloss applicator of  claim 2 , wherein an application tip provided on the tip connecting rod of the brush rod has a replaceable structure. 
     
     
         10 . The refillable lip gloss applicator of  claim 3 , wherein a locking rim is further formed on the outer peripheral surface of the filling portion of the refill container. 
     
     
         11 . The refillable lip gloss applicator of  claim 10 , wherein a locking groove is further formed on an inner peripheral surface of the packaging container,
 wherein when coupling the packaging container to the filling portion of the refill container, the locking groove is fittedly coupled to the locking rim formed on the outer peripheral surface of the filling portion, thereby preventing the packaging container from being arbitrarily separated from the filling portion.   
     
     
         12 . The refillable lip gloss applicator of  claim 3 , wherein a reverse rotation prevention groove opposite to the reverse rotation prevention protrusion formed on the upper surface of the support rim of the refill container is further formed on an inner peripheral surface of a lower end of the brush rod cap that is configured to be opened and closed relative to the inlet of the refill container,
 wherein when the brush rod cap is completely closed, the reverse rotation prevention groove is fittedly engaged with the reverse rotation prevention protrusion, so the brush rod cap is prevented from being arbitrarily opened unless the brush rod cap is artificially opened.   
     
     
         13 . The refillable lip gloss applicator of  claim 11 , wherein an upper portion of the locking groove of the packaging container has an inclined entry surface widened upward to facilitate entry and coupling of the locking rim. 
     
     
         14 . The refillable lip gloss applicator of  claim 3 , wherein an application tip provided on the tip connecting rod of the brush rod has a replaceable structure.
