FIG.2

I7 ]VENTORS Abbot Greene Paul Demen ATTORNEY .able blank of sheet material which United States Patent Ofiice 3,322,323 Patented May 30, 1967 3,322,323 BOX CONSTRUCTION Abbot Greene, 24 Carter Road, and Paul Densen, 27 Colony Drive 13., both of West Orange, NJ. 07052 Filed June 24, 1965, Ser. No. 466,751 15 Claims. (Cl. 229-37) This invention relates to a box construction, and more particularly to a collapsible box which can be readily erected from a collapsed position to an erected position, and which is especially constructed so that a plurality of similarly erected boxes can be detachably connected in either the side-by-side and/or end-to-end relationship to define a cluster of boxes which can be readily handled as a single unit to facilitate the handling-of the same.

Many articles are packed in cardboard cartons and the like to facilitate handling and shipping of the articles packed therein. Frequently, such cartons while relative- 1y light in weight when filled, are nevertheless bulky and cumbersome to handle. For this reason, each such carton or box was required to be handled one by one, as in loading or unloading the same onto a vehicle, truck, freight car, and the like. Consequently, in handling and/or storing such boxes as in loading or unloading a truck, warehouse, freight car, or the like, a considerable amount of time and labor was expended in moving each such carton one at a time, even though a loader was capable of lifting a weight much greater than that of the loaded carton. Consequently, if a loader was able to simultaneously lift a plurality of such bulky cartons, the number of handlings or trips required to load or unload a freight car, for example, can be reduced to a minimum.

It, therefore, is an object of this invention to provide an improved box construction specifically constructed so that a plurality of similarly constructed boxes may be detachably connected in a simple and expedient manner to one another to form a cluster that can be readily handled as easily as a single individual box thereof.

It is another object of this invention to provide a box construction having external portions thereof coated with a pressure sensitive adhesive whichwill adhere only to a surface coated with a similar pressure adhesive material.

It is another object of this invention to provide a box construction which can be readily collapsed between an operative and inoperative position whereby a similar blank of collapsed boxes may be stacked one on the other without adhering to one another.

Another object of this invention is to provide an improved box construction which can be readily erected from a collapsed position into an erected box position, and which is provided with coated portions of a pressure sensitive adhesive tothat a plurality of similarly constructed boxes in the erected position thereof can be detachably connected in side-by-side and/or end-to-end relationship to define a cluster of such boxes.

In accordance with this invention, the foregoing objects and other features and advantages are attained by a box construction which is preferably formed of a foldcan be readily stacked one on the other in the intermediate or collapsed position of the box, and which box in the erected position thereof can be readily detachably connected in either side by-side and/or end-to-end relationship to define a cluster of similarly constructed boxes. Essentially, the box comprises a blank of foldable sheet material arranged to define a plurality of side panels to define a closed figure in the erected position thereof. Top and bottom closure means are provided for closing the ends of the box. Means in the form of a layer or coating of a pressure sensitive adhesive material is applied to the external surfaces of the blank. In accordance with this invention,

a layer or coating of pressure sensitive material is applied to the side panels of the box which are co-planarly disposed in the collapsed position thereof. Accordingly, the arrangement is such that a plurality of blanks in the intermediately folded or collapsed position thereof can be readily stacked one on the other without causing adjacent collapsed blanks to adhere to one another. If desired, the closure means connected to the opposed ends of one of the coated panels may also be provided with a layer .of pressure sensitive material on the exterior surface thereof. Thus, the erected position of the box, at least two sides, and a portion of the top and bottom end closures of the erected box are provided with an exposed coating of pressure sensitive adhesive. When similarly constructed boxes are disposed into contacting sideby-side relationship with the coated panel portions thereof disposed contiguous to one another, the coated portions of one box will adhere to the adjacent coated portions of another box. With a plurality of such boxes thus detachably secured together, it will, therefore, become apparent that an operator charged with the task of loading and unloading such cartons onto a truck, for example, may readily lift several of those boxes even though he can only grasp one of them.

A feature of this invention resides in the provision of a readily collapsible box construction provided with external coated portions of a pressure sensitive adhesive that will adhesively secure or connect to a similar box when the respective coated portions thereof are disposed into contacting relationship with respect to one another.

Another feature of this invention resides in the provision whereby the box construction can be readily collapsed between an erected and collapsed position in such a manner that the blanks of similar collapsed boxes can be readily stacked one on the other without having the coated portions of adjacent blanks adhering to one another.

Another feature of this invention resides in the provision that the blank defining the box is formed from a single blank of sheet material which is die-cut and scored so as to define a plurality of side panels connected in end to-end relationship to define a closed figure, and which has connected to the upper lower ends of the respective side panel hinged flaps which are folded relative to the respective side panels to form the top and bottom closures of the box.

Another feature of this invention resides in the provision of a plurality of similar constructed boxes that can be readily detachably connected to one another to form a cluster so that a plurality of such boxes when secured to one another may be handled with the ease and facility of a single box.

A feature of this invention resides in the provision of a box construction which can be readily stacked in a manner so that a plurality of boxes are positively maintained in stacked position one on the other, boxes so stacked are prohibited from falling.

Other features and advantages will become more readily apparent when considered in view of the drawings in Which:

FIGURE 1 illustrates the outer side of an expanded blank from which a box is formed in accordance with the invention.

FIGURE 2 illustrates the perspective view of an erected box construction formed of the blank construction from FIGURE 1.

FIGURE 3 illustrates the collapsed or intermediate folded position of the box in FIGURE 2, to show how a plurality of such collapsed boxes can be readily stacked one on the other.

FIGURE 4 illustrates a perspective view of a plurality of box constructions, as

shown in FIGURE 2, adhesively secured together in side-by-side relationship to define a cluster in accordance with the instant invention.

FIGURE 5 is a perspective view illustrating how the box construction of FIGURE 2 can be clustered in either side-by-side and/ or end-to-end relationship.

Referring to the drawings, there is shown in FIGURE 1 an expanded blank from which a rectangular slotted type container or box 11 is formed in accordance with this invention. As shown, the blank 10 from which a box is formed is die-cut and scored to define a plurality of panels 12, 13, 14., connected in side-by-side relationship. The arrangement is such that the respective side panels 12, 13, 14, and 15 can be readily folded along transversely extended fold lines F1, F2, and F3 to define a substantially rectangularly shaped container or box 11, as disclosed in FIGURE 2. The upper and lower edge portions of the respective side panels have hingedly connected thereto end closure fiaps 12A, 12B; 13A, 13B; 14A, 14B; 15A, 15B; which in the erected portion of the container are adapted to be folded to define the top and bottom of the container 11. As shown in the illustrated embodiment, the width of the respective closure flaps are coextensive with the width of the panel connected thereto. As best seen in FIGURE 2 the respective top and bottom closure flaps are each provided with a width which is substantially equal to one-half the width of the adjacent side panel. Accordingly, in the erected box position, the respective free edge of the complementary top and bottom closure flaps, hingedly connected to the opposed side panels of the box, are arranged to be disposed in contiguous relationship with respect to one another. Suitable means, e.g., gluing and staples or the like may be provided for securing the end closure flaps in their folded or sealed position as indicated in FIGURE 2.

In the collapsed or intermediate position of the blank 10, the opposed edge of the blanks are disposed into contiguous relationship and suitably glued, or secured by tape so that the blank may be readily folded between an erected position as shown in FIGURE 2 and a collapsed or intermediate folded position, as shown in FIGURE 3.

Referring to FIGURE 3, it will be noted that the blank '10 is folded so that a pair of panels 14, 15 are disposed in overlying relationship to the other pair of panels 12, 13. Accordingly, a plurality of such collapsed blanks 10 may be readily stacked one on the other to conserve storage space thereof until ready for use.

Since the box construction of the type herein described is commonly used to receive various articles for shipment, such boxes are frequently quite bulky, even though when loaded they may be relatively light in weight. Consequently, because of such bulk, a person handling such boxes may not conveniently handle more than one such box at a given time. Consequently, in accordance with this invention, a means is provided whereby an operator or handler of such boxes may conveniently lift two or more such cartons or boxes, even though previous to this invention considerable difiiculty would have been encountered in handling a plurality of similar boxes.

This is attained by detachably securing a plurality of such boxes in a cluster of two or more such boxes. As shown, this is attained by applying to prescribed external portions of the blank or box, a coating of pressure sensitive adhesive 16 of the type which will adhere only to surface which is coated with a similar pressure sensitive adhesive.

As best seen in FIGURE 3, the layer 16 of such pressure sensitive adhesive is applied to at least two of the panels 14, 15 of the box or blank, and preferably to the two panels which are co-planarly disposed in the collapsed or intermediate folded position of the box or blank. In the illustrated embodiment, the layer of pressure sensitive adhesive 16 is applied in the form of two spaced strips which extend transversely across two adjacent panels at a predetermined interval. Accordingly, in the erected position of the box as shown in FIGURE 2, two adjacent side panels 14-, 15 of the box construction are provided with laterally extending strips or coated portions of a pressure sensitive adhesive. As seen in FIGURE 4, by disposing the coated side portions of two or more similarly constructed boxes, as herein described, into contacting relationship, the boxes 11 become detachably secured as the coated portion of one box will adhere to the coated portion of a similar box. Accordingly, the force of the adhesion between adjacent boxes is sufliciently great so that boxes so joined can be readily handled as a unit, yet rendered readily separatable without destroying the continuity of the individual box. Accordingly, even though the boxes are relatively bulky, but light in weight, a handler may handle several boxes simultaneously and, therefore, minimize much of the motion which was heretofore expended in handling such individual boxes.

In order that the box construction herein described may be also stacked and detachably secured to form clusters in which the boxes are stacked in end-to-end relationship, the closure flaps connected to at least one of the coated panels of the box are likewise provided with a layer of pressure sensitive material on the external surface thereof. As seen in FIGURES 1, 2, 3, and 4, at least one of the closure flaps 15A, 15B at both the top and bottom end of the box have an external surface thereof coated with a pressure sensitive material. Accordingly, when similarly constructed boxes are stacked on top of another, the coated portions of one of the top closing flaps of one box will adhere to the bottom flap of the box stacked thereon when properly placed thereon. It will be noted that when such boxes are stacked in a column, that the positive adhesion afforded between adjacent stacked boxes 11 will function to prevent any such column or stack of boxes from collapsing when subjected to jarring, as for example in shipment by truck or rail. Consequently, the positive stacking afforded by the adhesion obtained between the adjacent end portions of boxes so stacked further minimizes damages to the articles packed therein.

While the instant invention has been described with re spect to a particular box construction, it will be readily apparent that the concept described may be applied to any suitable box construction wherein portions of the sides and/or ends of the box are externally coated with a layer of pressure sensitive material so that the same can detachably adhere to a box construction having a similar coated portion thereon. Accordingly, it is conceivable that a box having three, four or more sides can be coated so as to form a cluster pack as herein described and shown.

While the instant invention has been described with reference to a particular embodiment thereof, it will be readily appreciated and understood that variations and modifications of the same may be made without departing from the spirit or scope of the invention.
