The present invention includes a scalpel blade removal device with an opening in a wall defining a first blade guide, extending to a narrowing upward ramp bounded by left and right guide walls. A horizontal top ramp extends from the distal end of the upward ramp, bounded by left and right guide towers. A spring loaded notch device is adapted to lock behind a proximal end of a scalpel blade seated on a scalpel, where the scalpel is inserted in the opening and the blade edge is driven up the ramp to the top ramp. When the notch device is locked behind that end of the scalpel blade, the scalpel is pulled back, causing the scalpel blade to slide off the scalpel handle. A sharps container incorporates the removal device, a reinforced latch, a scalpel resting location, and needle cover removers. |

1. A sharps container box having a separately unitarily molded top half and bottom half incorporating into one of four sidewalls of the bottom half a scalpel blade remover adapted to remove a scalpel blade from a scalpel handle, each scalpel blade having a rear edge which abuts a rear surface of a neck of the scalpel handle in a locking relationship, the handle further having a blade locking portion provided at a front end thereof and grooves provided along the periphery of the blade locking portion, the scalpel blade also having a slot for receiving the grooves of the blade locking portion of the scalpel handle, the grooves being slidable in the slot and passing through a wider opening at a portion of the slot to permit the blade to be removed from the blade locking portion, the scalpel blade remover comprising:
(a) a vertical rectangular opening defined in a sidewall and a bottom floor's edge of the bottom half, extending upward and inward from the bottom floor's edge a ramp at from 30 degrees to 60 degrees to an elevation from 0.25 to 1.5 inches from the bottom floor, the ramp being supported by a left wall, back wall, and right wall; (b) a notched extension extending rearward from near an inside surface of the sidewall to the left of the rectangular opening, the notched extension being curved at a distal end into a space inwardly normal to the rectangular opening, whereon said distal end is a defined notch inward directed, the notched extension having an elevation greater than the back wall by greater than 0.25 inches, and a cutout is defined in the ramp around the notched extension allowing deflection of said distal end to the left; (c) a left guide wall extending inward from the back wall, rising from the bottom floor to an elevation more than 0.25 inches above the top of the back wall, and having a right side aligned with a right edge of the rectangular opening; (d) a right guide wall extending inward from the back wall, rising from the bottom floor to an elevation more than 0.25 inches above the top of the back wall, and having a left side aligned spaced apart from the right side of the left guide wall by a thickness of the blade locking portion; (e) the right wall extending from a front edge of the right guide wall convexly along the ramp to a right edge of the rectangular opening; and (f) the blade remover is adapted so that: (i) a tip of a scalpel blade fixed to a scalpel handle may be moved past the rectangular opening to force a bottom edge of the blade to slide up the ramp and come to rest on a top edge of the back wall resulting in said distal end to be deflected substantially to the left; and (ii) the distal end of the notched extension is urged to the right to engage the rear edge of the scalpel blade, whereupon a user draws the scalpel handle outward from the sidewalls to disengage the scalpel blade from the scalpel handle.
