     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0021]    A detailed description of the present invention will now be described with reference to the drawings. 
         [0022]    A locking device capable of securing a bag according to the present invention is for the items storing bag comprising a cover  10  used to seal an opening of a bag and a body  20  for storing various items therein. 
         [0023]    A first embodiment of the present invention will now be described. As shown in  FIGS. 1 to 4 , the cover  10  forms a hole  11 . The hole  11  serves so that a locking insertion member  30  and an elastic fastening member  40  are assembled to the cover  10 . When they are assembled the locking insertion member  30  is positioned outside of the cover  10  and the elastic fastening member  40  is positioned inside of the cover  10 . 
         [0024]    The locking insertion member  30  includes a body  31  covered its top with a reinforcement element  35  for its strength, and a locking insertion protrusion  32  formed on the body  31  for the insertion to the hole  11 . The locking insertion protrusion  32  forms a tapered surface  34  toward the cover  10  to have a increased diameter gradually and forms a locking groove  33 . The top of the tapered surface  34  is its diameter larger than that of the hole  11 . 
         [0025]    The elastic fastening member  40  includes a body  41  and a hole  42 . The hole  42  enables the locking insertion member  30  to be fastened to the elastic fastening member  40  via the cover  10  since the locking insertion protrusion  32  of the locking insertion member  30  is inserted into the hole  42  after passed through the hole  11  of the cover  10 . The body  41  forms a downwardly tapered surface  41   b  for preventing the separation of the locking insertion member  30 . 
         [0026]    The elastic fastening member  40  is formed its end with the bending portion for keeping a gap from the cover  10 . The gap serves to prevent a damage of the cover  10 . Furthermore, the elastic fastening member  40  forms an embossing  43  for preventing an excessive contact to the cover  10 . These structures of the elastic fastening member  40  serve to prevent a damage of the cover  10 . The embossing  43  is formed in the manner of a press working and is formed its opposition side with a concave portion  43   a.    
         [0027]    Meanwhile, as shown in  FIGS. 13 and 14 , it is possible that the protrusion  32  of the locking insertion member  30  is formed to have a pin shape and the elastic fastening member  40  is formed for inserting the protrusion  32 . In this case, after the protrusion  32  is inserted into the fastening elastic member  40 , the lower part of the protrusion  32  is its shape changed to have an extended diameter when the top of the protrusion  32  is pressed down using a tool. Therefore, the protrusion  32  is not separated from the elastic fastening member  40 . 
         [0028]    The body  20  forms a hole  21  for assembling a fastening member  50 , a lower member  60 , an elastic locking member  70  and an upper member  80 . 
         [0029]    The fastening member  50  includes a body  51 , and a fastening protrusion  52  for securing the lower member  60  via the hole  21 . The protrusion  52  is inserted into a hole  62  of the lower member  60 , and thereafter its top is pressed down to have a larger diameter than that of the hole  62 . The portion pressed down of the protrusion  52  is tightly contacted to the inner bottom surface of the lower member  60  so that the fastening member  50  and the lower member  60  are tightly fastened each other. 
         [0030]    The lower member  60  includes a body  61 , and a hole  62  for inserting the protrusion  52  of the fastening member  50  passed through the hole  21  of the body  20 . 
         [0031]    The elastic locking member  70  is made of metal, non-metal or plastic. The elastic locking member  70  includes a circular plate  71  fastened to the inner bottom of the lower member  60 . The circular plate  71  forms an elastic insertion portion  72  having a triangle shape for inserting the protrusion  32  of the locking insertion member  30  fastened to the cover  10 . The plate  71  also forms a tapered surface  73  having a certain slope upwardly except the elastic insertion portion  72 , and a hole  74  for the locking and unlocking of the locking groove  33  of the locking insertion member  30  fastened to the cover  10 . The hole  74  opens in the central portion of the elastic insertion portion  72 . 
         [0032]    The elastic locking member  70  can forms a plurality of tapered surfaces  73  so that the protrusion  32  can be softly separated from the elastic locking member  70  by the elastic force so that the damage such as its breakdown can be prevented. 
         [0033]    The upper member  80  includes a body  81  for covering the lower member  60 , a hole  82  for inserting the protrusion  32  of the locking insertion member  30  fastened to the cover  10  and for inserting the protrusion  52  of the fastening member  50  fastened to the body  20 , and a tapered surface  83  having a certain slope upwardly from the hole  82  for easily inserting the protrusion  31  to the hole  82 . 
         [0034]    Next, the assembly steps of the locking device capable of securing the bag having the above constructions will now be described. 
         [0035]    As shown in  FIGS. 1 to 3 , the protrusion  32  of the locking insertion member  30  is inserted into the hole  11  of the cover  10  and is inserted into the hole  42  by the elastic force of the elastic fastening member  40  without difficulty. Then the protrusion  32  can be prevented the separation from the elastic fastening member  40  because the tapered surface  34  is its top diameter larger than that of the hole  42 . Therefore, the locking insertion member  30  and the elastic fastening member  40  are assembled to the cover  10 . 
         [0036]    As shown in  FIG. 4 , under a state that the elastic locking member  70  is put on the inside bottom of the lower member  60 , the lower member  60  is covered with the upper member  80 . The protrusion  52  is inserted into the hole  21 , then the top of the protrusion  52  is passed through the hole  62 . Under this state, the top of the protrusion  52  is pressed down so that the top diameter of the protrusion  52  became larger than that of the hole  62 , and accordingly the fastening member  50  and the lower member  60  are combined each other. As a result of that, the fastening member  50 , the lower member  60 , the elastic locking member  70  and the upper member  80  are assembled to the body  20 . 
         [0037]    Next, the locking operation of the device will now be described. 
         [0038]    The protrusion  32  is inserted into the hole  74  through the hole  82  so that the locking groove  33  of the protrusion  32  is locked by the hole  74 . 
         [0039]    Since the tapered portion  73  keeps a certain slope upwardly from the hole  74  under the state that the elastic locking member  70  is tightly contacted to the inside bottom of the lower member  60 , the separation of the protrusion  32  can be prevented. That is, to be separated the protrusion  32  from the hole  74 , the tapered portion  73  should be gone upwardly according to the movement of the protrusion  32 . However, the movement like that is not easily possible due to the slope degree of the tapered portion  73 . Therefore, the locking state can be kept. 
         [0040]    The unlocking operation is adversely performed of the operation of the locking. 
         [0041]    A second embodiment of the present invention will now be described. The locking device capable of securing the bag according to the second embodiment of the present invention, as shown in  FIGS. 5 to 7 , changes the structure of the locking insertion member  30 . 
         [0042]    The locking insertion member  30  forms a fastening protrusion  38  on the lower surface of the protrusion  32  for preventing the separation from the cover  10 . 
         [0043]    When the protrusion  32  of the locking insertion member  30  is inserted into the hole  42  of the elastic fastening member  40  via the hole  11 , the fastening protrusion  38  is also passed through the hole  42  via the hole  11 . Therefore, since the diameter of the protrusion  38  is larger than that of the hole  42 , the locking insertion member  30  is fastened to the elastic fastening member  40  via the cover  10 . 
         [0044]    A third embodiment of the present invention will now be described. The locking device capable of securing the bag according to the third embodiment of the present invention, as shown in  FIGS. 9 and 10 , changes the structure of the locking insertion member  30 . 
         [0045]    The locking insertion member  30  forms a groove  37  on the lower surface of the protrusion  32  for being inserted with a C-shaped ring  39 . The ring  39  has a lager diameter than that of the protrusion  32 . Therefore, when the ring  39  is inserted into the groove  37 , the surface surrounded with the ring  39  is its diameter larger than that of the surface of the protrusion  32 . 
         [0046]    Therefore, the locking insertion member  30  is prevented the separation from the cover  10  and the elastic fastening member  40 . 
         [0047]    Under a state that the protrusion  32  of the locking insertion member  30  is inserted into the hole  11  of the cover  10 , the ring  39  is combined to the groove  37  so that the locking insertion member  30  is prevented the separation from the elastic fastening plate  40 . 
         [0048]    A fourth embodiment of the present invention will now be described. 
         [0049]    The locking device capable of securing the bag according to the fourth embodiment of the present invention, as shown in  FIGS. 11 and 12 , changes the structures of the elastic fastening member  40  and the upper member  80 . 
         [0050]    The elastic fastening member  40  forms dissected protrusions  41   a  on the hole  42 . The protrusions  41   a  are bent toward the outer surface of the protrusion  32  of the locking insertion member  30 . 
         [0051]    The upper member  80  forms a tapered surface  83  that is upwardly slope from the hole  82 . The tapered surface  83  serves that the protrusion  32  is guided and easily inserted into the hole  82 . 
         [0052]    Under a state that the locking groove  33  of the protrusion  32  is protruded outside of the cover  10 , the locking insertion member  30  is assembled to the elastic fastening member  40  across the cover  10  by the tapered portion of the protrusion  32  and the end of the protrusion  31   a  since the end of the protrusion  41   a  is kept the contact state with the outer face of the protrusion  32 . 
         [0053]    Furthermore, since the tapered portion  83  is formed to have a downwardly slope toward the hole  82  the protrusion  32  is easily inserted into the hole  82  using the tapered portion  83 .
