Locking device capable of securing a bag

Abstract

Disclosed is a locking device capable of securing a bag for securing both an item storing body and a cover used to seal an opening of a bag in a closed configuration to protect the contents within the bag. The cover assembles a locking insertion member and the elastic fastening member. The item storing body assembles a fastening member, a lower cap member, an elastic locking member and an upper cap member.

What is claimed : 
     
         1 . A locking device capable of securing a bag comprising:
 a cover formed a hole;   a locking insertion member including a body, a locking insertion protrusion having a locking groove and a tapered portion for inserting to the hole of the cover, and a reinforcement element covered the body for increasing strength;   an elastic fastening member including a body, a hole for inserting the locking insertion protrusion passed through the hole of the cover so that the locking insertion member is assembled via the cover, a downwardly tapered surface, an embossing for preventing an excessive contact to the cover, wherein said elastic fastening member is formed its end with the bending portion for keeping a gap from the cover, and is formed with a concave portion at the opposite side of the embossing;   an item storing body formed a hole;   a fastening member including a body, and a protrusion for inserting into the hole of the item storing body;   a lower cap including a body, and a hole for inserting the protrusion of the fastening member passed through the hole of the item storing body;   an elastic locking member including a circular plate fastened to the inner bottom of the lower member, wherein said circular plate forms an elastic insertion portion for inserting the protrusion of the locking insertion member fastened to the cover, a tapered surface having at least one or more slopes upwardly except the elastic insertion portion, and a hole for the locking and unlocking of the locking groove of the locking insertion member fastened to the cover; and   an upper cap including a body for covering the lower cap, and a hole for passing through the protrusion of the locking insertion member and the protrusion of the fastening member.   
     
     
         2 . The device according to  claim 1 , wherein the tapered portion of the elastic locking member has at least one or more predetermined slopes. 
     
     
         3 . The device according to  claim 1 , wherein the protrusion of the locking insertion member is formed to have a pin shape and the elastic fastening member is formed for inserting the protrusion of the locking insertion member, so that the protrusion is not separated from the elastic fastening member by an extended diameter of the protrusion. 
     
     
         4 . The device according to  claim 1 , wherein the locking insertion protrusion of the locking insertion member has another protrusion for preventing the separation from the cover and the elastic fastening member. 
     
     
         5 . The device according to  claim 1 , wherein the locking insertion protrusion forms a groove so that a ring is inserted thereto for preventing the separation from the cover and the elastic fastening member. 
     
     
         6 . The device according to  claim 1 , wherein the elastic fastening member forms dissected protrusions on the hole, said protrusions being bent toward the outer surface of the protrusion of the locking insertion member. 
     
     
         7 . The device according to  claim 1 , wherein the upper member forms a tapered surface that is upwardly slope from the hole.
