     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]    In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims. 
         [0018]    A material box  1  comprises: 
         [0019]    A seat  10  has a through hole  12  at an upper portion of the seat  10 . By the through hole, the box can be hung on an object. One lateral side of the seat  10  has a breakable portion  13 . An inner edge of the breakable portion  13  connecting to the seat  10  is formed with holes or is thinned so that the breakable portion  13  can be broken from the seat  10 . Preferably the seat  10  is made of hard plastics. 
         [0020]    A receiving space  14  is formed at a lower portion of the seat  10  for receiving other objects, such as an electronic element. 
         [0021]    A cover  11  as illustrated in  FIG. 1A  for covering the seat  10 . In  FIG. 1A , it is illustrated the cover  11  can directly cover the seat  10  from the upper side thereof, or as illustrated in  FIG. 1B , the cover  11  is connected to the seat  10 , and the connecting area  100  of the cover  11  and the seat  10  is bendable. Thus, the cover  11  can be bent easily to cover the seat  10 . Preferably, the cover  11  is made of soft plastics. Preferably, as the cover  11  covers the seat  10 , the receiving space  14  of the seat  10  is tightly sealed so as to tightly seal an object received in the receiving space  14 . The cover  11  has two buckles  50  which can be buckled into a trench  141  near edges of the receiving space  14  so that the cover  11  can be tightly engaged to the seat  10 . The sealing film  3  is made of soft and easy-tearable film. 
         [0022]    Referring to  FIGS. 1 and 2 , and further referring to  FIGS. 3A and 3B , where  FIG. 3A  is an assembled view showing that the cover covers upon the box of the present invention; and  FIG. 3B  is another assembled view showing the film  3  covers upon the cover of the present invention. 
         [0000]    It is illustrated that the present invention further comprise a sealing film  3  which adheres on an upper side of the cover  11 . The sealing film  3  has at least one tearing line  301  formed to be corresponding to the edges of the cover  11  (referring to  FIG. 3B ). When the cover  11  is opened upwards, the sealing film  3  will be broken along the tearing line. The portion of the sealing film  3  originally adhering on the cover  11  still adheres on the cover and is separated from the other portion of the sealing film  3 . Besides, the sealing film  3  includes an easy tearing portion  31  which can be torn away from the sealing film  3  easily. One end of the easy tearing portion  31  adheres on the breakable portion  13 . 
         [0023]    With reference to  FIG. 4A , in operation, the breakable portion  13  is torn away from the seat  10  easily. Since one end of the easy tearing portion  31  is adhered on the breakable portion  13 , when the breakable portion  13  is taken away from the seat  10 , it will drive the easy tearing portion  31  to tear away from the sealing film  3 . Then, referring to  FIG. 4B , an edge of the upper cover  11  exposes out and the user can open the cover  11  from the seat  10 . Then a portion of the sealing film  3  on the cover  11  will tear away from the other portion of the sealing film  3  easily. As a result the user can take out the element located in the receiving space  14  of the seat  10 . 
         [0024]    It should be noted, in the present invention the space of the receiving space  14  is not confined to the shape illustrated in the drawing. Other shapes are permissible in the present invention, such as a round shape, a rectangular shape, a polygonal shape, etc. All these are within the scope of the present invention. 
         [0025]    Advantages of this embodiment will be described herein. In the present invention, the user can break the breaking portion  3  easily so as to tear away the sealing film and thus the upper cover is opened for taking out the element in the receiving space of the seat  10 . Since the sealing film is adhesive, it can be used repeatedly. The box of the present invention is anti-electromagnetic, anti-dust and anti wet. Moreover, the friction effect can be avoided and the vibration is reduced. 
         [0026]    Referring to  FIGS. 5A and 5B , another embodiment of the present invention is illustrated. In this embodiment, those identical to the former embodiment are identified with the same number and the details will not be further described herein. Other those different from the former embodiment are described herein. 
         [0027]    A material box  1  comprises the following elements: 
         [0028]    A seat  10  has a through hole  12  at an upper portion of the seat  10 . By the through hole, the box can be hung on an object. One lateral side of the seat  10  has a breakable portion  13 . An edge of the breakable portion  13  connecting to the seat  10  is formed with holes or is thinned so that the breakable portion  13  can be broken from the seat  10 . 
         [0029]    A receiving space  14  is formed at a lower portion of the seat  10  for receiving other objects, such as an electronic element. 
         [0030]    A sealing film  3  adheres on an upper surface of the receiving space  14 . The sealing film  3  has at least one tearing line  301  which is positioned to be corresponding to the edges of the receiving space. When a portion of the sealing film covering the receiving space is torn away, the sealing film  3  will be broken along the tearing line  301  and thus is separated from the other portion of the sealing film. The sealing film includes an easy tearing portion  31  which can be torn away from the other portion of the sealing film easily, and one end of the easy tearing portion  31  adhering on the breakable portion  13 . Usually, the easy tearing portion  31  is confined by two tearing lines as illustrated in the drawings. 
         [0031]    When the breakable portion  13  is torn upwards, the sealing film  3  will be broken along the easy tearing portion  31 . The portion of the sealing film  3  originally adhering on the seat  10  still adheres thereon. Then the portion of the searing film  3  covering the receiving space  14  can be torn away along the boundary thereof. 
         [0032]    Advantages about this embodiment will be described herein. In the present invention, the user can break the breaking portion  3  easily so as to tear away the sealing film and thus receiving space is opened for taking out the element therein. Since the sealing film is adhesive, it can be used repeatedly. The box of the present invention is anti-electromagnetic, anti-dust and anti wet. Moreover, the friction effect can be avoided and the vibration is reduced.
