Storage box

Abstract

A storage box includes a box body defining a storage chamber and an access opening and having multiple first engagement portions at one side of the access opening, and a liftable lid, which includes multiple second engagement portions and is pivoted to the box body and biasable relative to the box body between a close position where the second engagement portions are disengaged from the first engagement portions and the liftable lid closes the access opening, and a lifted position where the second engagement portions are engaged with the first engagement portion and the liftable lid is kept away from the access opening to keep the storage chamber in an open status. Thus, the user does not need to hold the liftable lid in the lifted position with the other hand when using one hand to put things in the storage chamber of the box body.

What is claimed is: 
     
         1 . A storage box, comprising:
 a box body comprising a storage chamber, an access opening in communication with said storage chamber, first pivot connector means extending along one side of said access opening, and at least one first engagement portion formed at said first pivot connector means; and   a liftable lid comprising a second pivot connector means disposed at one side thereof and at least one second engagement portion formed at said second pivot connector means, said second pivot connector means being coupled to said first pivot connector means in such a manner that said liftable lid is biasable relative to said box body between a close position where said at least one second engagement portion of said liftable lid is disengaged from said at least one first engagement portion of said box body and said liftable lid closes said access opening, and a lifted position where said at least one second engagement portion of said liftable lid is engaged with said at least one first engagement portion of said box body and said liftable lid is kept away from said access opening to keep said storage chamber in an open status.   
     
     
         2 . The storage box as claimed in  claim 1 , wherein said first pivot connector means of said box body comprises at least one smoothly arched hook and at least one pair of opposing second retaining protrusions disposed inside said at least one smoothly arched hook; said second pivot connector means of said liftable lid comprises a pivot axle inserted through said at least one smoothly arched hook and pivotally secured to said at least one smoothly arched hook by said at least one pair of opposing second retaining protrusions; said at least one second engagement portion of said liftable lid each is formed of one rib protruded from the periphery of said second pivot connector means; said liftable lid further comprises at least one opening disposed adjacent to said pivot axle for the passing of said at least one smoothly arched hook of said first pivot connector means when said liftable lid is being biased relative to said box body. 
     
     
         3 . The storage box as claimed in  claim 2 , wherein said first pivot connector means of said box body comprises a slot on each said smoothly arched hook, and a elastic element suspending in the slot on each said smoothly arched hook and terminating in one said first engagement portion. 
     
     
         4 . The storage box as claimed in  claim 2 , wherein said box body comprise a body shell and a cover shell, said body shell, said body shell defining therein said storage chamber and said access opening, said cover shell being covered on said body shell and carrying said first pivot connector means and said at least one first engagement portion. 
     
     
         5 . The storage box as claimed in  claim 4 , wherein said box body comprises a rim and a plurality of notches; said cover shell comprises a plurality of retaining lugs respectively inserted into said notches of said box body, and a plurality of first retaining portions respectively protruded from said retaining lugs and forced into engagement with said rim of said box body.
