Abstract:
A secure container includes a housing and a hinged door, the housing including an inner shell, an external shell, and a plurality of fastening brackets. The external shell surrounds the inner shell. The fastening brackets are inserted and fixed between the receiving space defined between the inner shell and the external shell. Each fastening bracket defines a plurality of first through holes through which a filler can be introduced, the fastening brackets lending strength and a particular placement to the filler.

Description:
FIELD 
       [0001]    The subject matter herein generally relates to secure containers, such as safes. 
       BACKGROUND 
       [0002]    Secure containers, such as safes, may include, for example, an inner steel plate and an external steel plate. Concrete can fill the space between the inner steel plate and the external plate. The distance between the inner steel plate and the external plate can be made larger to allow the concrete to be thicker, but that may unreasonably increase the weight of the safe.

     DETAILED DESCRIPTION 
       [0009]    It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein. 
         [0010]    A definition that applies throughout this disclosure will now be presented. 
         [0011]    The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like. 
         [0012]      FIGS. 1 to 2  illustrate a secure container (safe)  100 . The safe  100  includes a housing  10  and a door  60  hinged to the housing  10 . 
         [0013]    An exemplary housing  10  defines an accommodation space  11  for accommodating objects. The housing  10  includes an external shell  20 , a number of fastening brackets  30 , an inner shell  40 , and blocking plates  50 . The external shell  20  surrounds the inner shell  40 . Also referring to  FIG. 5 , the inner shell  40  and the external shell  20  define a receiving space  55 , therebetween. The fastening brackets  30  are received in the receiving space  55 . The blocking plate  50  seals the receiving space  55 . The receiving space  55  is configured to be filled with a filler, such as concrete. The external shell  20  includes a first bottom plate  21 , two first side plates  22 , a first rear plate  23  and a first top plate  24 . The two first side plates  22  are perpendicularly connected to two opposite edges of the first bottom plate  21 . The first rear plate  23  is perpendicularly connected to an end of the first bottom plate  21  and is connected between the two first side plates  22 . The first top plate  24  is parallel to and positioned above the first bottom plate  21 . The first bottom plate  21 , the first side plate  22 , the first rear plate  23 , and the first top plate  24  are connected together by welding or other secure means. 
         [0014]      FIGS. 4-5  illustrate the fastening bracket  30  received in the receiving space  55  and being fixed to the external shell  40 . The fastening bracket  30  may be made of steel. The fastening bracket  30  is fixed to the external shell  40  by welding.  FIG. 3  illustrates that the fastening bracket  30  includes a base plate  31 , two connecting plates  32 , and two fixing plates  33 . The two connecting plates  32  obliquely extend from two opposite sides of the base plate  31  and extend towards each other. A angle between the connecting plate  32  and the base plate  31  is acute, being between about 20° and about 85°. The two fixing plates  33  extend from two edges of the two connecting plates  32  away from the base plate  31  and apart from each other in a co-planar fashion. The two fixing plates  33  are parallel to the base plate  31 . An edge of the fixing plate  33  away from the connecting plate  32  extends beyond the base plate  31 . The base plate  30  and the fixing plate  33  are in an alternating fashion fixed either to the external shell  20  or to the inner shell  40 . 
         [0015]    The connecting plate  32  defines a number of first through holes  321 . The first through hole  321  enables the filler to easily fill the receiving space  55 . The fixing plate  33  can be connected to the inner shell  40  by welding. The base plate  31  defines a number of second through holes  311 . The second through holes  311  are welding points. The base plate  31  can be welded to the external shell  20  through the second through holes  311 . 
         [0016]      FIGS. 2 and 5  illustrate that the inner shell  40  includes a second bottom plate  41 , two second side plates  42 , a second rear plate  43 , and a second top plate  44 . The two second side plates  42  are perpendicularly connected to two opposite edges of the second bottom plate  41 . The second rear plate  43  is perpendicularly connected to an end edge of the second bottom plate  41  and is connected between the two second side plates  42 . The second top plate  44  is parallel to and positioned above the second bottom plate  41 . The second bottom plate  41 , the second side plate  42 , the second rear plate  43 , and the second top plate  44  are connected together by welding. The second bottom plate  41 , the second side plate  42 , the second rear plate  43 , and the second top plate  44  correspond on a to the first bottom plate  21 , the first side plate  22 , the first rear plate  23 , and the first top plate  24 , respectively. 
         [0017]    The fastening brackets  30  are fixed between the external shell  20  and the inner shell  40 . The base plate  30  and the fixing plate  33  are fixed in an alternating fashion to the external shell  20  and the inner shell  40 . The second bottom plate  41  and the second top plate  44  define two pouring holes  45 . The filler passes through the pouring holes  45  to fill the receiving space  55 . The use of the fastening brackets  30  to allow for less filler material to need to be used and allow for the weight of the secure container to be reduced. 
         [0018]    The door  60  includes a frame  61  and a door panel  62  rotationally attached to the frame  61 . The frame  61  is fixed to the blocking plate  50 . The frame  61  defines an opening  615  which defines the internal volume of the safe  100 . The frame  61  can be fixed to the blocking plate  50  by welding. A handle  625  protrudes from an external side of the door panel  62  for closing or opening the door panel  62 . The door may include a lock, not shown.
