Air inflow interruptible tube container

Abstract

The present invention relates to an air inflow interruptible tube container. The air inflow interruptible tube container can prevent a corruption of contents, by installing a nozzle rising and opened by a pressure of contents inside an outlet part to allow the nozzle to be opened only when the contents are discharged, maintaining a closed state of an outlet hole of the nozzle unless the contents are discharged even when a cap is opened, and thus preventing air from flowing into a tube body through the outlet hole.

What is claimed is: 
     
         1 . An air inflow interruptible tube container comprising:
 a tube body containing contents and comprising an outlet part formed at an upper portion thereof to discharge the contents;   an internal nozzle comprising a coupling part inserted into the outlet part and having a content inflow hole communicating with the outlet part, and a blocking rod upwardly protruding from a central portion of the coupling part;   an external nozzle seated on an upper end of the coupling part while covering the blocking rod, rising and falling by a pressure of the contents, and open and closed by the blocking rod;   a fixing body coupled to an inner side of the outlet part while covering a portion of the external nozzle and comprising a hollow part to allow the external nozzle to rise and fall;   an elastic body disposed inside the fixing body while surrounding the external nozzle to allow the external nozzle to fall; and   a closing cap coupled to an outer side of the outlet part while covering the internal nozzle and the external nozzle.   
     
     
         2 . The air inflow interruptible tube container of  claim 1 , wherein the external nozzle comprises:
 a seating part having a piston structure in which an upper end portion and a lower end portion of an outer circumferential surface thereof contact an inner wall surface of the fixing body; and   a content movement tube upwardly extending from the seating part to form a passage through which the contents move and having an outlet hole opened/closed by the blocking rod.   
     
     
         3 . The air inflow interruptible tube container of  claim 1 , wherein the fixing body comprises a seating stopper surrounding an outer circumferential surface of the fixing body and seated on an upper end of the outlet part and a fixing protrusion formed under the seating stopper to be fixed to an inner side of the outlet part. 
     
     
         4 . The air inflow interruptible tube container of  claim 1 , wherein the fixing body comprises an elastic body supporting stopper formed at an upper end of the fixing body to support the elastic body while surrounding an inner circumferential surface of the fixing body. 
     
     
         5 . The air inflow interruptible tube container of  claim 1 , wherein the internal nozzle comprises a blocking protrusion formed at a lower end thereof to block the contents moving through the outlet part from leaking out of the internal nozzle. 
     
     
         6 . The air inflow interruptible tube container of  claim 1 , wherein the closing cap comprises a pressurizing protrusion formed an upper portion of an inner side thereof to pressurize the external nozzle. 
     
     
         7 . The air inflow interruptible tube container of  claim 3 , wherein the closing cap comprises a coupling restriction protrusion formed on an inner side of the closing cap and seated on the seating stopper of the fixing body to restrict screw-coupling when the closing cap is screw-coupled to the outlet part.
