  • Patent number: 4436243
    Abstract: The storage file is of the temporary type, made up of a box stamping comprising initially a flat sheet such as cardboard provided with appropriate fold lines. The fold lines define a top, left and right sides, a bottom and front and rear ends for folding these components into a box shape. A tray receivable in the box is also formed from a stamping initially starting with a flat sheet which again may be cardboard and having fold lines to define a floor and left and right sides and front and rear ends for the tray. These components again are folded into the tray structure. The tray may optionally be provided with a divider element again formed from a flat sheet appropriately folded to be received in the tray. The storage box is ideally suited for slides and tissue blocks used in medical work. The initial flat configuration of the sheets for making up the box permits compact storage and easy shipment as well as economical manufacture.

  • Patent number: 4277015
    Abstract: A container for produce and the like is formed by a pair of endwalls and a wrapper. The wrapper is divided by score lines into a floor panel, a pair of sidewalls, a pair of cover flaps and a pair of joiner strips by which the flaps are connected to the sidewalls. The joiner strips permit the flaps to be shifted laterally as well as pivotally. Each flap has a tab at each end thereof that is received, when the flap is closed, in a recess between two lugs on one of the endwalls. The tabs can shift laterally as permitted by undercut portions of the recesses, and must be so shifted and then bowed before they can be withdrawn from the recesses so that the flaps can be opened pivotally.

  • Patent number: 4273548
    Abstract: A blank is folded to form a box by pressing it into a jig. End and side panels of the blank, along with supplemental panels at the corners, are lifted relative to a floor panel by folding surfaces of the jig. The side panels are lifted first and supplemental end panels are thus positioned inside the end panels. The blank may also include supplemental side panels that are folded outwardly and backwardly by corner guides of the jig.

  • Patent number: 4266714
    Abstract: Boxes for produce and the like formed by corrugated paperboard containers having end walls defining vertical slots that are aligned when the containers are stacked. Column-forming members are inserted in the slots and interlocked vertically. The containers are supported primarily by the inserts so that the combined weight of containers above is not borne solely by the end walls.

  • Patent number: 4211358
    Abstract: A lug box having cored-out plastic end walls and a wrapper, preferably of corrugated paperboard, that is nailed to the end walls. The wrapper is formed by a single piece including bottom and side panels as well as foldably attached lid flaps that provide a top for the box. Each end wall has parallel ribs extending along its bottom and side edges that receive the nails. Reinforcing ribs in the center sections of the end walls lend added rigidity and strength.

  • Patent number: 4170313
    Abstract: A box folded from a box blank. The box blank has a nominally planar bottom member and four nominally planar sidewall members. The sidewall members are disposed in a cruciform array. Each of said members has an edge. Respective edges of the bottom member and sidewall members are adjacent to each other in pairs, and are laterally spaced apart from one another along a respective fold axis. A strap hinge is respective to each pair of edges, joining the members together whereby to permit rotation of the members relative to one another along the fold axis. A tooth is formed on one of the members and a recess is formed in the other of the members, the tooth and recess each having a restraint face which when engaged by the other restrains the member from lateral translational separation normal to the fold axis along the plane of one of the members. The box blank is preferably made of molded plastic and can be formed in a single piece.

  • Patent number: 4147289
    Abstract: A lug box composed of two end walls of generally rectangular conformation, composed of plastic material, and a wrapper extending between and overlapping vertical side edges and bottom of the end walls. The end walls are cored-out for lightness, but also to provide multiple ribbed structures through which nails are driven from the outside to enhance the degree of securement of the wrapper to the end walls.

  • Patent number: 4078656
    Abstract: A package is provided for containing and delivering to a physician, laboratory or hospital a glass slide fastened removably in position, spatula, tongue depressors, etc., for use in obtaining a specimen, and retaining it on the glass slide during transportation to the laboratory for analysis. The package comprises two side panels, joined by a narrow end wall, with end walls also at the remote ends of the panels, also edge walls, and side flaps. After the specimen has been deposited on the glass slide, the side flaps are severed, so they can be folded over independently of one another. The package can then be folded into a smaller one, more compact by about one-half the original length, for transportation or mailing to the laboratory. Features are provided for protection of the deposit on the glass slide from the opposed wall portions of the package.

  • Patent number: 3989140
    Abstract: The invention provides cleats or bars for interlocking produce lug boxes at the top tier of multiple tier columns of such boxes arranged on a pallet in a unitized stack. The lug boxes have rectangular plastic frames at their ends, surmounted by spacers, and the invention provides cleats or bars which clamp to these spacers at the top of the stack. The end frames of the containers engage end-frame to end-frame in the stack, and are provided with interlocking elements which prevent lateral shifting of individual containers. In combination with the use of these interlocking elements, the clamping bars at the top provide an especially well integrated stack of containers. In addition, certain binding tapes are used, and these interengage with guides and recesses in the end frames and locking bars to unitize and stabilize the stack. The clamping bars also provide flat platforms on which can be mounted a second pallet supporting a second stack of containers.
