FIELD OF THE INVENTION
The present invention relates to a stackable, nestable storage box for use in securing personal items by people living in group settings. The box has a lockable, removable lid adapted to resist removal by flexing the sides of the box.
BACKGROUND OF THE INVENTION
Storage boxes or tote boxes are known in the prior art. These boxes may be made of metal, plastic or composites. The design adapts to nesting for storage and shipping and stacking, allowing one box containing material to be stacked on another. Securing the contents in the box requires a closure that resists removal. Lids used to close prior art boxes may be removed by flexing the box with the lid on to spring the lid off the box opening.
Prior art lids may be adapted to fit with features on the bottom of the box to facilitate stacking when the lid is on the box. The lids in the prior art may be removably fitted to the box top. Prior art lids may be dislodged from the top of the box by flexing the box causing the walls to disorientate and come apart from the lid.
Accordingly, it is desirable to provide a storage box having a lid which is interlocked with the open edge of the box to prevent the lid coming off of the box in the event that the boxes dropped or otherwise has the sides flexed. There is an aid to provide a storage box for intensive use applications which minimizes the use of fasteners while providing more impact-resistance, less weight and high-volume.
SUMMARY OF ONE EMBODIMENT OF THE INVENTION
The present invention comprises a storage box having a generally rectangular bottom molded with four connecting sidewalls extending away from the bottom to form an open ended box having an upper edge around the opening. A horizontal box flange extends outwardly from the box opening surrounding the box opening and interconnecting the sidewalls. The horizontal box flange extends around the perimeter of the box opening. The horizontal box flange is generally parallel with the bottom of the box and providing a surrounding ledge around the perimeter of the open top of the box. The horizontal box flange extends outwardly from the box opening. The horizontal box flange has an inside edge connected to the sidewalls and end walls of the box and an outside edge defining a flange perimeter, a top side and a bottom side.
A vertical box flange is on the outside edge of the horizontal box flange. The vertical box flange extends upward to define the upper edge of the open box opening. The vertical box flange may comprise a box portion that is continuous around three sides of the box opening and an end portion adjacent the fourth side of the box opening. A pair of rib openings are formed between the box portion and the end portion. The end portion extends along the top edge of the second end wall. The end portion has a first end that is spaced from a first end of the vertical box flange and a second end that is spaced from a second end of the vertical box flange, thereby creating the pair of rib openings in the vertical box flange at the corners between the second end wall and each of the sidewalls. The vertical box flange may be on the outer perimeter on the outer edge of the horizontal box flange directed outward away from the open box and generally perpendicular to the bottom of the box.
The rib opening is generally at the corner of the box forming a rib engagement channel on the top side of the horizontal box flange along the first and third vertical box flanges to the rib opening at each corner adjacent the second end wall.
The lid may have a generally flat panel approximately the size and shape of the open top of the box. Several bosses may be formed in the flat panel projecting outward from the inside of the box to engage indentations formed on the bottom panel to facilitate stacking and prevent shifting position when a first box is stacked on a second box having the bosses extending into the respective indentations.
The lid may further comprise a box edge rail formed on each of two opposing sides and one end. The box edge rail surroundingly engages the continuous vertical box flange to prevent the box sides from being deformed to disengage the lid from the box. A vertical surround flange may be formed on three sides of the lid to wrap around the upper edge of the box. The vertical surround flange formed on a second end of the lid and extending along each adjacent side of the lid may be disposed comprises a vertical member extending from a bottom side of the flat panel of the lid adapted to surroundingly engage the box portion of the vertical box flange. A horizontal surround flange on the vertical surround flange may be generally horizontal and adapted to slide under the horizontal box flange.
The lid may further comprise a plurality of ribs extending from the bottom surface of the lid along the first and second opposing sides. The ribs are spaced from the vertical surround flange and are disposed in a parallel orientation to the vertical surround flange and adjacent to the inside edge of the vertical surround flange. Each rib may have an engagement portion generally parallel to the lid flange vertical member and an engagement member positioned at an angle from the flange vertical member. The engagement member forming an opening between the lid flange vertical member and the engagement portion. Several ribs may be formed along each edge of the lid forming an edge channel between the several ribs and the vertical surround flange. The engagement member closest to the first end of the lid.
