Tube vessel with wide nozzle

Abstract

The present disclosure relates to a tube vessel with a wide nozzle, more particularly a tube vessel with a wide nozzle in which an outer cap is rotatably coupled to an inner cap, and in a process of the outer cap being screw-coupled to a tube neck, the inner cap descends as being pressurized by the outer cap; thereby, a wide nozzle gets sealed through an opening/closing protrusion of the inner cap. Therefore, in a process of being screw-coupled or being released from a screw coupling, smoothly the wide nozzle performs opening/closing, such that it is possible to provide user convenience.

What is claimed is: 
     
         1 . A tube vessel with a wide nozzle comprising:
 a tube body wherein contents are held;   a tube neck coupled to an upper portion of the tube body and supporting the tube body, further comprising a first screw thread at an outer circumferential surface and a wide nozzle formed with a width length longer than a height length;   an outer cap further comprising a second screw thread for being detachably coupled to the tube neck in screw-coupling;   an inner cap coupled to an inner side of the outer cap, further comprising an opening/closing protrusion at an upper inner side thereof for opening/closing the wide nozzle by attaching/detaching of the outer cap,   characterized in that the outer cap is rotatably coupled on the inner cap, and the wide nozzle is closed through an opening/closing protrusion while the inner cap is pressurized by a descent of the outer cap and descends downwards in a process of screw-coupling the outer cap to the tube neck.   
     
     
         2 . The tube vessel with a wide nozzle of  claim 1 , wherein a rotation guide groove is provided at an outer circumferential surface of the inner cap for guiding an independent rotation of the outer cap, and a coupling protrusion coupled to the rotation guide groove is provided at an inner circumferential surface of the outer cap. 
     
     
         3 . The tube vessel with a wide nozzle of  claim 2 , wherein a protrusion is provided at an upper portion of the rotation guide groove of the inner cap such that the coupling protrusion of the outer cap moves upwards in a state of being coupled to the rotation guide groove and is prevented from being separated from the rotation guide groove. 
     
     
         4 . The tube vessel with a wide nozzle of  claim 2 , wherein a securing protrusion pressurized by the coupling protrusion is provided at a lower portion of the rotation guide groove of the inner cap such that the inner cap can descend together along while the outer cap is descending by a screw-coupling of the outer cap and the tube neck. 
     
     
         5 . The tube vessel with a wide nozzle of  claim 3 , wherein the coupling protrusion pressurizes a lower end of the protrusion, when the outer cap and the tube neck are released from the screw-coupling, in a process of the outer cap ascending according to being released from the screw-coupling, and thereby the inner cap ascends together along, such that the opening/closing protrusion of the inner cap is separated from the wide nozzle and opens the wide nozzle.
