Opening mechanism for a box

Abstract

A box includes an outer part having a body, a cover pivotably connected to the body, and a space defined between the body and the cover. The inner part includes an operation portion which protrudes from outside of the inner part. An opening mechanism is configured between the outer part and the inner part. By applying a force to the opening mechanism, the inner part is raised so as to push the cover away from the outer part.

1 . A box comprising:
 an outer part having a body, a cover which is pivotably connected to the body, and a space defined between the body and the cover;   an inner part located in the space and having an operation portion which protrudes from outside of the inner part, and   an opening mechanism configured between the outer part and the inner part, comprising at least two slots respectively defined in two opposite sides of an inner surface of the body, at least one guiding surface extending from the outer part to the space, at least one notch defined in outside of the inner part, at least two protrusions configured on an outer surface of the inner part, wherein the notch is slidably engaged with the guiding surface, the protrusions are movably engaged with the slots.   
     
     
         2 . The box as claimed in  claim 1 , wherein outer surfaces of the body, the cover and the operation portion are flush with each other. 
     
     
         3 . The box as claimed in  claim 1 , wherein the slot is an inclined slot, a curved slot, a waved slot or the combination thereof, and the guiding surface is an inclined surface, a curved surface, a waved surface or the combination thereof. 
     
     
         4 . The box as claimed in  claim 1 , wherein the notch and the guiding surface have the same shape. 
     
     
         5 . The box as claimed in  claim 1 , wherein the slots extend upwardly and rearwardly at an angle. 
     
     
         6 . The box as claimed in  claim 1 , wherein the protrusions movably engage the slots to provide an upward movement for the inner part.
