Fastening structure and seal box with the fastening structure

Abstract

The present invention discloses a fastening structure having a fastening flange extended outward from the periphery of a cover, and the fastening flange has a latch portion under the fastening flange for latching and fixing the cover; and a hinge portion for connecting the fastening flange at the periphery of the cover, and the hinge portion has a plurality of sections of crevices for reducing a hinge area that connects the fastening flange to the cover. The invention also discloses a sealed box that includes the fastening structure, and a container having a latch structure disposed at a top edge of the container and used together with the latch portion for latching and fixing the cover. Without changing the thickness of the hinge portion, the invention can save efforts for the operation of the sealed box while maintaining the stress of the hinge portion.

1 . A fastening structure, disposed at a periphery of a cover and comprising:
 at least one fastening flange extended outward from the periphery of said cover, and having a latch portion disposed under said fastening flange; and   a hinge portion, for connecting said fastening flange with the periphery of said cover, and having a plurality of sections of crevices, for reducing a hinge area that connects said fastening flange and said cover.   
   
   
       2 . The fastening structure of  claim 1 , wherein said hinge portion has a thickness smaller than that of said fastening flange, such that said fastening flange can be folded from said hinge portion and stacked onto said cover. 
   
   
       3 . A sealed box, comprising:
 a cover, having a plurality of fastening flanges disposed at the periphery of said cover and a latch portion disposed under said fastening flange;   a hinge portion, coupled to the periphery of said cover at said fastening flange, and having a plurality of sections of crevices, for reducing a hinge area that connects said fastening flange to said cover; and   a container, having a latch structure disposed proximate to a top edge of said container and used together with said latch portions for fastening and fixing said cover with said container.   
   
   
       4 . The sealed box of  claim 3 , wherein said hinge portion has a thickness smaller than that of said fastening flange, such that said fastening flange can be folded and stacked onto said cover by said hinge portion. 
   
   
       5 . The sealed box of  claim 3 , wherein said latch structure comprises a sunken latch portion, for pressing and latching said latch portions into said latch portion. 
   
   
       6 . The sealed box of  claim 3 , wherein said cover has a recession coupled to the top of said container, and said recession includes a pad for sealing said container. 
   
   
       7 . The sealed box of  claim 3 , wherein said has a sheathe hole disposed at a cover surface of said cover, and said sheathe hole has at least one air hole disposed adjacent to the periphery of said sheathe hole; and an umbrella valve, including a diaphragm with a sufficient width to cover said air hole, a press button disposed above said diaphragm, and a blocking latch portion disposed under said diaphragm and provided for inserting into said sheathe hole. 
   
   
       8 . The sealed box of  claim 7 , wherein said cover has an indent sunken into said cover surface, and said sheathe hole is disposed at said indent.
