     The closure of a vessel in accordance with the present invention includes a body  56  mounted at an inlet  52  through which contents contained in a vessel  50  is discharged out, and having an outlet  54  through which the contents stored in the vessel  50  is discharged out at an upper surface thereof, a sealing member removing unit  60  formed at the body  56 , for removing a sealing member  58  sealing the inlet  52  when the closure is detached from the inlet  52 , and storing the removed sealing member  58  in the body  56 ; and a cover  62  openably mounted at the body  56 , for opening and closing the outlet  54 . 
     The sealing member  58  for protecting the contents stored in the vessel  50  by sealing the inlet  52  through which the contents is discharged out is attached to the inlet  52 . Preferably, the sealing member  58  is formed of a material such as paper or thin aluminum that can be easily removed by a knife, etc. 
     A first mounting portion  64  for mounting the sealing member removing unit  60  is concavely formed at an upper surface of the body  56 , and a second mounting portion  66  formed with the outlet  54  and equipped the cover  62  disposed at an opposite side to the first mounting portion  64  in a radial direction is concavely formed at an upper surface of the body  56 . 
     The outlet  54  is provided with a discharge amount controlling unit  68  for controlling a discharge amount of the contents stored in the vessel. The discharge amount controlling unit  68  includes a partitioning bar  70  disposed at a middle portion of the outlet  54 , for partitioning the outlet  54  into two parts; and a mesh-typed net  72  disposed at one part of the outlet  54 , for controlling a discharge amount of the contents. 
     When the vessel is a little inclined, a little amount of the contents is discharged out through the mesh-typed net  72  of the discharge amount controlling unit  68 . And, when the vessel is more inclined, a large amount of the contents is discharged out through the entire outlet  54  of the discharge amount controlling unit  68 . 
     A female screw portion  74  coupled to a male screw portion  76  formed at an outer circumferential surface of the inlet  52  is formed at an inner circumferential surface of a lower surface of the body  56 . 
     The sealing member removing unit  60  includes: a pressing plate  80  disposed in the first mounting portion  64  of the body  56 , the pressing plate  80  being movable in upper and lower directions, and pressed by a user; a cutter  82  formed at an outer edge of a lower surface of the pressing plate  80 , for penetrating the sealing member  58  when the pressing plate  80  is pressed, and for cutting the sealing member  58  when the body  56  is rotated; a locking portion  84  formed at an inner edge of the lower surface of the pressing plate  80 , for locking the sealing member  58  so as to store the sealing member  58  cut by the cutter  82  in the body  56 ; and a connecting portion  86  connecting an outer circumferential surface of the pressing plate  80  and an inner circumferential surface of a through hole formed at the first mounting portion  64 , for guiding the pressing plate  80  to be movable in upper and lower directions and supporting a moved position of the pressing plate  80  by its own elastic force. 
     The pressing plate  80  is long disposed at the body  56  in a radial direction so as to be positioned in the first mounting portion  64 , and is formed in a disc shape having a radius smaller than that of the body  56 . 
     As shown in  FIG. 6 , the cutter  82  includes a supporting portion  90  formed at an outer edge of a lower surface of the pressing plate  80 ; a first cutting portion  92  sharply formed at a lower end of the supporting portion  90 , for penetrating the sealing member  58  by being downwardly moved when the pressing plate  80  is pressed; and a second cutting portion  94  formed on at least one of two sides of the supporting portion  90 , and rotated with a contacted state to an inner circumferential surface of the inlet  52  when the body  56  is rotated, thereby cutting the sealing member  58  as a circular shape. 
     As shown in  FIG. 7 , the locking portion  84  includes a supporting rod  96  downwardly extending from the center of a lower surface of the pressing plate  80 , for penetrating the sealing member  58  when the pressing plate  80  is pressed; and at least one locking rod  98  formed at an outer circumferential surface of a lower portion of the supporting rod  96 , for locking the sealing member  58  so that the sealing member  58  cut by the cutter  82  may be stored in the body  56 . 
     The supporting rod  96  is formed in a cylindrical bar downwardly and perpendicularly extending from the center of the pressing plate  80 , and a punch portion  100  having a sharp shape for forming a hole at the sealing member  58  is formed at the end of the supporting rod  96 . 
     The locking rod  98  is formed to be elastically transformable in an upper direction, and at the time of penetrating the sealing member  58 , the locking rod  98  is upwardly bent thus to penetrate the sealing member  58  through a hole formed by the punch portion  100 , and after the locking rod  98  penetrates the sealing member  58 , it is straightened into the original state thus to be locked at an inner surface of the sealing member  58 . 
     The locking rod  98  is perpendicularly extending from the outer circumferential surface of the supporting rod  96  with a certain length, and one or more locking rods  98  are formed. Preferably, a pair of locking rods  98  are formed on the outer circumferential surface of the supporting rod  96  with an interval of 180°. 
     The connecting portion  86  is formed as a thin film of dome type for connecting an inner circumferential surface of the first mounting portion  64  of the body  56  to an outer circumferential surface of the pressing plate  80 , and the connecting portion  86  is elastically transformable when the pressing plate  80  is pressed, thereby guiding the pressing plate  80  so as to be downwardly moved. 
     The connecting portion  86  elastically maintains a current position of the pressing plate  80 . More concretely, when the pressing plate  80  is upwardly protruding without being pressed, the connecting portion  86  maintains the current position of the pressing plate  80  by maintaining a dome shape, and when the pressing plate  80  is pressed, the connecting portion  86  is elastically transformable as a concave shape thereby to maintain the pressed position of the pressing plate  80 . 
     The cover  62  is formed in a plate type having the same size as the second mounting portion  66  so as to be inserted into the second mounting portion  66  formed at the body  56 , and one end of the cover  62  is rotatably connected to an upper surface of the body  56  by a connecting rib  102 , and the other end thereof is downwardly bent to be inserted into an edge of the second mounting portion  66 . 
     A supporting film  61  for maintaining an opened state of the cover  62  and preventing the contents discharged to the outlet  54  from being leaked to the side is formed between the edge of the cover  62  and the edge of the second mounting portion  66 . 
     The supporting film  61  is implemented as a triangular thin film, and one side of the supporting film  61  is connected to both sides of the cover  62 , and the other side of the supporting film  61  is connected to both edges of the second mounting portion  66 , and a foldable portion  63  is formed at the center of the supporting film  61 . 
     The foldable portion  63  is formed to be inward-concavely folded so as to be foldable into the cover  62  when the cover  62  is closed. 
     A security member  104  for preventing the pressing plate  80  from being pressed by an external impact is mounted at an upper surface of the body  56 . 
     The security member  104  is disposed to cover an upper surface of the pressing plate  80 . One end of the security member  104  is rotatably connected to one edge of the first mounting portion  64 , and the other end thereof is detachably mounted at another edge of the first mounting portion  64 , and accordingly, the security member  104  prevents the pressing plate  80  from being pressed by an external impact. 
     One end of the security member  104  is rotatably integrally formed at one edge of the first mounting portion  64  by a connecting rib  106 , and the other end thereof is detachably locked by a locking groove  108  formed at the other edge of the first mounting portion  64 , thereby forming a locking jaw  110  coupled to the body  56 . Not only the locking groove  108  and the locking jaw  110  but also various structures may be detachably mounted between the security member  104  and the body  56 . Preferably, the security member  104  is integrally formed at the body  56 . 
     An operation of the security member  104  will be explained. The security member  104  disposed to cover the upper surface of the pressing plate  80  prevents the pressing plate  80  from being arbitrarily pressed. When the pressing plate  80  is to be pressed by a user, after the security member  104  is detached from the body  56 , the locking jaw  110  formed at the security member  104  is detached from the locking groove  108  formed at the edge of the first mounting portion  64 . Accordingly, the security member  104  is rotated centering around the connecting rib  106  thus to be detached from the upper surface of the pressing plate  80 . 
     As another embodiment, the security member  104  may be implemented as a reinforcing rib (not shown) integrally connecting the edge of the pressing plate  80  and the edge of the first mounting portion  64  and torn away when a force more than a certain degree is applied thereto. An operation of the closure of a vessel will be explained. 
       FIGS. 8 ,  9  and  10  are views showing an operation state of the closure of a vessel according to the first embodiment of the present invention. 
     First, a locked state of the security member  104  covering the upper surface of the pressing plate  80  is released, and then the security member  104  is rotated thus to be detached from the upper surface of the pressing plate  80 . Then, the pressing plate  80  disposed at the first mounting portion  64  of the body  56  is downwardly pressed so as to outwardly discharge the contents stored in the vessel  50 . Accordingly, the connecting portion  86  is elastically deformed, and the pressing plate  80  is downwardly moved. Herein, the first cutting portion  92  of the cutter  82  formed at the outer edge of the lower surface of the pressing plate  80  penetrates the edge of the sealing member  58 , and the supporting rod  96  of the locking portion  84  penetrates the center of the sealing member  58 . 
     The locking rod  98  of the locking portion  84  penetrates the sealing member  58  with an upwardly bent state through a hole formed by the punch portion  100  of the supporting rod  96 . Once the locking rod  98  penetrates the sealing member  58 , it is straightened into the original state thus to be positioned at an inner surface of the sealing member  58 . 
     Then, if the body  56  is rotated by the user&#39;s hand, the female screw portion  74  formed at the inner circumferential surface of the body  56  rotates along the male screw portion  76  formed at the inlet  52 . Accordingly, the body  56  is detached from the inlet  52 . Herein, the cutter  82  rotates with a contact state to the inner circumferential surface of the inlet  52 , so that the second cutting portion  94  cuts the sealing member  58  in a circular form. 
     Since the sealing member  58  removed from the inlet  52  is locked by the locking rod  98  of the locking portion  84 , it is detached from the inlet  52  together with the body  56  thus to be received in the body  56 . 
     The sealing member  58  received in the body  56  is taken out of the body  56 , and then the body  56  is coupled to the inlet  52 . Then, the cover  62  mounted at the body  56  is opened to discharge out the contents stored in the vessel  50  through the outlet  54  formed at the body  56 . Herein, the supporting film  61  prevents the cover  62  from being closed when the contents stored in the vessel is discharged out, and prevents the contents discharged through the outlet  54  from being leaked to the side. 
       FIG. 11  is a perspective view showing a closure of a vessel according to the second embodiment of the present invention, and  FIG. 12  is a sectional view showing the closure of a vessel according to the second embodiment of the present invention. 
     A closure of a vessel according to the second embodiment of the present invention comprises: a body  56  mounted at an inlet  52  through which contents contained in a vessel  50  is discharged out, and having an outlet  54  through which the contents is discharged out at an upper surface thereof, a sealing member removing unit  60  formed at the body  56 , for removing a sealing member  58  sealing the inlet  52  when the closure is detached from the inlet  52 , and storing the removed sealing member  58  in the body  56 ; a cover unit  130  openably mounted at the body  56 , for opening and closing the outlet  54 ; and a security member  104  rotatably mounted at an upper surface of the body  56 , for preventing the pressing plate  80  from being arbitrarily pressed. 
     A first mounting portion  132  for mounting the sealing member removing unit  60  is disposed at one side of the body  56  in a radial direction with a radius longer than that of the body  56 , and a second mounting portion  134  having the outlet  54  through which the contents is discharged out is disposed to face the first mounting portion  132 . 
     The first mounting portion  132  is formed to be downwardly convexed, and to have a radius longer than that of the body  56 . The second mounting portion  134  is detached from the first mounting portion  132  by a partition wall  136 , and has a radius shorter than that of the body  56 . Herein, the partition wall  136  partitions the first mounting portion  132  and the second mounting portion  134  from each other together with a protrusion  141  protruding from a lower surface of a cover portion  142 . 
     The sealing member removing unit  60  of the second embodiment has the same construction as the sealing member removing unit  60  of the first embodiment except that the pressing plate  80  is disposed at a position lower than an upper surface of the body  56 . 
     The cover unit  130  includes a hinge protrusion  140  hinge-connected to both edges of the first mounting portion  132 ; a cover portion  142  formed at one side of the hinge protrusion  140 , covering the second mounting portion  134 , and locked by the second mounting portion  134 ; and an operation rod  144  formed at the other side of the cover portion  142  and extending towards the first mounting portion  132 , for opening and closing the cover portion  142 . 
     The operation rod  144  disposed on an upper surface of the pressing plate  80  is pressed together with the pressing plate  80  when the pressing plate  80  is pressed. Herein, the hinge protrusion  140  serves as a lever, and the cover portion  142  is upwardly moved to be opened. A locking protrusion  145  for maintaining a pressed state of the operation rod  144  by being locked to both edges of the operation rod  144  when the operation rod  144  is pressed is protruding from both inner surfaces of the first mounting portion  132 . 
     That is, the operation rod  144  is locked by the locking protrusion  145  when pressed thus to maintain the pressed state, thereby maintaining an opened state of the cover portion  142 . Then, if the operation rod  144  is pressed in a direction that the cover portion  142  is closed, it is detached from the locking protrusion  145  thus to be upwardly moved. 
     The security member  104  has the same structure as the security member  104  of the first embodiment except that it is disposed to cover an upper surface of the operation rod  144  so as to prevent the pressing plate  80  and the operation rod  144  from being pressed. 
     An operation of the closure of a vessel according to the second embodiment will be explained.  FIG. 13  is a view showing an operation state of the closure of a vessel according to the second embodiment of the present invention. 
     First, the security member  104  is removed. A locked state of the security member  104  is released, and then the security member  104  is rotated thereby to expose the pressing plate  80  and the operation rod  144  outwardly. Under the state, if the pressing plate  80  and the operation rod  144  are pressed together, the pressing plate  80  is lowered thus to remove the sealing member  58  and to store the sealing member in the body  56  as aforementioned in the first embodiment. 
     When the operation rod  144  is downwardly moved, the cover portion  142  is upwardly moved centering the hinge protrusion  140 . The cover portion  142  is detached from the second mounting portion  132  thus to be opened, thereby opening the outlet  54  formed at the body  56 . Herein, since both side surfaces of the operation rod  144  are locked by the locking protrusion  145  protruding from both inner surfaces of the first mounting portion  132 , the operation rod  144  maintains the pressed state. 
     If the operation rod  144  is pressed together when the pressing plate  80  is pressed, the cover unit  130  is rotated centering around the hinge protrusion  140  and the cover portion  142  is upwardly moved thus to open the outlet  54 . Accordingly, the user does not have to open the cover from the second mounting portion  66 . 
       FIG. 14  is a perspective view showing a closure of a vessel according to the third embodiment of the present invention, and  FIG. 15  is a perspective view showing a lower portion of the closure of a vessel according to the third embodiment of the present invention.

     The closure of a vessel of the fourth embodiment has the same operation as the closure of a vessel of the third embodiment except that the cutter  202  is a plate type having a certain length. Accordingly, the sealing member  58  is cut by approximately ¼˜½ when the pressing plate  200  is pressed, and the sealing member  58  is entirely cut when the body  56  is rotated by an angle equal to or less than 180°. 
       FIG. 19  is a perspective view showing a closure of a vessel according to the fifth embodiment of the present invention, and  FIG. 20  is a sectional view showing the closure of a vessel according to the fifth embodiment of the present invention. 
     The closure of a vessel according to the fifth embodiment comprises: a body  56  mounted at an inlet  52  through which contents stored in a vessel  50  is discharged out; a sealing member removing unit  250  integrally formed in the body  56 , for removing a sealing member  58  sealing the inlet  52  when the closure is detached from the inlet  52 , and storing the removed sealing member  58  in the body  56 ; and a cover  256  rotatably hinge-connected to the pressing plate  252  of the sealing member removing unit  250 , for opening and closing the outlet  254  formed at the pressing plate  252 . 
     A female screw portion  74  coupled to a male screw portion  76  formed at an outer circumferential surface of the inlet  52  is formed at a lower inner circumferential surface of the body  56  in a circumferential direction. An inner surface of the body  56  is penetrated so as to mount the sealing member removing unit  250 , and a groove  258  for inserting a user&#39;s finger so as to open and close the cover  256  is formed at one side of the body  56 . 
     The sealing member removing unit  250  includes: a pressing plate  252  disposed in the body  56  so as to be movable in upper and lower directions, and having an outlet  254  through which contents stored in the vessel is discharged out at one side thereof, a cutter  260  formed at an outer edge of a lower surface of the pressing plate  252 , for penetrating the sealing member  58  when the pressing plate  252  is pressed, and for cutting the sealing member  58  when the body  56  is rotated; a locking portion  262  formed at an inner edge of the lower surface of the pressing plate  252 , for locking the sealing member  58  so as to store the sealing member  58  cut by the cutter  260  in the body  56 ; and a connecting portion  264  connecting an outer circumferential surface of the pressing plate  252  and an inner circumferential surface of the body  56 , for guiding the pressing plate  252  to be movable in upper and lower directions and supporting a moved position of the pressing plate  252  by its own elastic force. 
     The cover  256  is rotatably mounted at an upper surface of the pressing plate  252  by a connecting rib  266 , and opens and closes the outlet  254  formed at the pressing plate  252 . 
       FIG. 21  is a view showing an operation state of the closure of a vessel according to the fifth embodiment of the present invention. 
     When the pressing plate  252  is pressed, it is downwardly moved and the cutter  260  formed at the edge of the pressing plate  80  penetrates the edge of the sealing member  58 . At the same time, the locking portion  262  penetrates the center of the sealing member  58 . 
     Then, if the body  56  is rotated by a user&#39;s hand, the female screw portion  74  formed at the inner circumferential surface of the body  56  is rotated along the male screw portion  76  formed at the inlet  52 , thereby separating the body  56  from the inlet  12 . Herein, the cutter  260  cuts the sealing member  58  in a circular form while rotating with a contact state to the inner circumferential surface of the inlet  52 . 
     Since the sealing member  58  removed from the inlet  52  is locked by the locking portion  262 , it is detached from the inlet  52  together with the body  56  thus to be received in the body  56 . The sealing member  58  received in the body  56  is taken out of the body  56 , and then the body  56  is coupled to the inlet  52 . Then, the cover  256  mounted at the pressing plate  252  is opened to outwardly discharge the contents stored in the vessel  50  through the outlet  254  formed at the pressing plate  252 . Herein, the user opens the cover  256  by putting his finger into the groove  258 . 
       FIG. 22  is a sectional view showing a closure of a vessel according to the sixth embodiment of the present invention, and  FIG. 23  is a view showing an operation state of the closure of a vessel according to the sixth embodiment of the present invention. 
     The closure of a vessel of the sixth embodiment has the same structure as the closure of a vessel of the first embodiment except that a sealing member removing unit  300  is operated to penetrate a sealing member. 
     The sealing member removing unit  300  of the sixth embodiment includes a pressing plate  302  disposed at an inner surface of the body by a connecting portion  304 , and a punch  306  protruding from a lower surface of the pressing plate  302  for forming a hole at the sealing member  58 . 
     The punch  306  has a sharp end and an inclined surface. When the pressing plate  302  is lowered, the punch  306  penetrates the sealing member  58  thus to form a hole  310  at the sealing member  58 . The cut portion of the sealing member  58  is disposed at an inner surface of the sealing member  58  as a folded state. 
     As shown in  FIG. 24 , since the sealing member  58  is provided with a mesh-typed reinforcing member  312  attached thereto, the other part of the sealing member  58  when the punch  306  forms the hole  310  in the sealing member  58  is prevented from being torn away. 
       FIG. 25  is a perspective view showing a closure of a vessel according to the seventh embodiment of the present invention, and  FIG. 26  is a perspective view showing a closure of a vessel having an opened cover according to the seventh embodiment of the present invention. 
     The closure of a vessel of the seventh embodiment includes a body  352  mounted at an inlet  52 , and having an outlet  350  through which contents stored in a vessel  50  is discharged out at an upper surface thereof, and a cover unit  360  rotatably mounted at the body  352 , for opening and closing the outlet  350 . 
     The cover unit  360  includes a hinge protrusion  362  hinge-connected to an upper surface of the body  352 ; a cover portion  364  formed at one side of the hinge protrusion  362 , for covering the outlet  350 ; and an operation rod  366  formed at the other side of the cover portion  364  and disposed at an insertion groove  370  concaved at an upper surface of the body  352 , for opening and closing the cover portion  142 . 
     A locking protrusion  361  for locking both side surfaces of the operation rod  366  is protruding from both inner surfaces of the insertion groove  370  so as to maintain a pressed state of the operation rode  366 . 
     At the time of opening the outlet  350 , the operation rod  366  is downwardly pressed and the hinge protrusion  362  serves as a lever. Accordingly, the cover portion  364  is upwardly moved and thus the outlet is opened. 
     Furthermore, since the operation rod  366  is locked by the locking protrusion  361 , the pressed state thereof is maintained and thus the cover portion  364  maintains an opened state. When the cover portion  364  is pressed in a closing direction, the operation rod  366  is detached from the locking protrusion  361  thus to be upwardly moved.
