CONTAINER Filed July 21, 1964 INVENTOR 2:7 1 r FHA/VA l V. Lot/r5- ATTORNEY United States Patent Ofifice Patented Apr. 26, 1966 This invention relates to an improvement in containers and deals particularly with containers designed to be quickly scalable for assembly line use yet collapsible and stackable for inexpensive shipping and storing prior to use. n In assembling a regular slotted container to receive an article, it is the usual practice to form the container and apply-an adhesive to the outside of the bottom end flaps and the inside of the bottom side flaps. The bottom side flaps are then folded into face contact with the bottom end flaps and are thereby secured.

Another method of preparing a regular slotted con- .tainer to receive an article is to fold the bottom end flaps inwardly and fold the bottom side flaps over the bottom end flaps into face contact. Tape may then be applied to the bottom side flaps to secure the bottom closure assembly.

A third method is to preapply a water-activated glue to the outside of the bottom end flaps and the inside of the bottom side flaps. With this construction, the preparation of a regular slotted container is much the same as in .the first method above except that water rather than glue is applied to the precoated surfaces.

A fourth method is the preapplication of a pressuresensitive adhesive, which adheres only to similar pressuresensitive adhesives, on the outside of the bottom end flaps and the inside of the bottom side flaps. The container is then assembled and secured by folding the bottom end flaps inwardly and folding the bottom side flaps into face contact.

All of the above methods are costly and time-consum ing. It is the object of my invention to eliminate many of the several steps necessary in preparing a container for receiving an article and to eliminate many of the steps necessary in manufacturing a container with quickly scalable means for securing bottom and top closure assemblies.

A feature of my invention lies in the formation of a quickly scalable container which may be collapsed without the preapplied pressure-sensitive adhesive coming in contact since there is no application of the pressure-sensitive adhesive on any of the inside flaps or panels. Size restrictions are not imposed on my container, since all coating is done on the outside of the flaps.

A further feature of my invention is that the container may be stacked without the preapplied pressure-sensitive adhesive coming into contact.

Another feature of my invention is thatthe pressuresensitive adhesive can be applied to the outside of the end flaps during manufacture. Since it is not necessary to coat both the inside and outside closure flaps, the steps of assembling the container prior to the application of the adhesive and then disassembling and restacking the container subsequent to the application of the adhesive are eliminated. In the present invention, the container need not be formed. The adhesive is simply applied to the outside of the appropriate flaps at the appropriate point in manufacture. The container blanks are then immediately stacked. There is no need to stack the container blanks, unstack them, and assemble them prior to the application of the pressure-sensitive adhesive and then disassemble the containers and restack them subsequent to the application of the pressure-sensitive adhesive.

These and other objects and novel features of my invention will be more clearly and fully set forth in the following specifications and claims.

FIGURE 1 is a diagrammatic view of the outside surface of the blank from which the container is formed, the shaded area being the surface upon which the pressuresensitive adhesive is preapplied.

FIGURE 2 is a diagrammatic view of the container shown in tubular arrangement before either the top or bottom flap assemblies are closed. The shaded area represents the surfaces upon which pressure-sensitive adhesive is preapplied.

FIGURE 3 is a diagrammatic view of the container as viewed looking down on the top of the container through the partially open top flap assembly to the inside of the closed bottom flap assembly.

FIGURE 4 is a cross-sectional view of the container in FIGURE 1, the section view taken on the line'4 4 and showing the inside of the top flap assembly in, closed position.

FIGURE 5 is a diagrammatic view of the container in closed position.

The container shape may, of course, be varied between wide limits, the container illustrated being a common size.

As illustrated in FIGURE 1, the container blank includes end wall panels 10 and 12 and side wall panels 11 and 13. End Wall panel 10 is hingedly connected to side wall panel 11 along fold line 14; side wall panel 11 is hingedly connected to end wall panel 12 along fold line 15, which is parallel to fold line 14; and end wall panel 12 is hingedly connected to side wall panel 13 along fold line 16, which is parallel to fold line 14.

FIGURE 1 shows container wall closure tab 18 hingedly connected to end wall panel 10 along fold line 1 7, which is parallel to fold line 14.

FIGURE 1 also shows the top and bottom closure assemblies. End closure flaps 20 are hingedly connected to end wall panel 10 along fold lines 24, which are perpendicular to fold line 14. Side closure flaps 21 are hingedly connected to side wall panel 11 along fold lines 25, which are extensions of fold lines 24. End closure flaps 22 are hingedly connected to end wall panel 12 along fold lines .26, which are extensions of fold lines 25. Side closure flaps 23 are hingedly connected to side Wall panel 13 along fold lines 27, which are extensions of fold lines 26.

FIGURE 1 also shows end closure flaps 20 hingedly connected to side closure flaps 21 along fold lines 14a, which are extensions of fold lines 14. Side closure flaps 21 are hingedly connected to end closure flaps 22 along fold lines 15a, which are extensions of fold line 15. End closure flaps 22 are hingedly connected to side closure flaps 23 along fold lines 16a, which are extensions of fold line 16. Tabs 18a are extensions of container closure tab 18 hingedly connected thereto along fold lines 24a, which are extensions of fold lines 24. Tabs 18a are hingedly connected to end closure flaps 20 along fold lines 1711 which are extensions of fold line 17, which is parallel to fold line 14.

As shown by FIGURE 1, each end closure flap 20 includes two fold lines 28 extending at angles of substantially 45 from the intersection of fold lines 24 and 18a, and 24 and 14a, respectively- The lines extend outwardly to the edge of each end closure flap 20. Each end closure flap 22 includes two fold lines 29 extending at angles of substantially 45 from the intersection of fold lines 26 and 15a, and 26 and 15a, respectively. The lines extend outwardly to the edge of each end closure flap.-

J abutting relations when the container is closed; consequently, the fold lines need not intersect at the edge of the end closure flap. 7

The shaded areas in FIGURE 1 represent the only surfaces upon which a pressure-sensitive adhesive is preapplied. The inner side of the end closure flaps is not coated nor is the inner side of the side closure flaps.

As shown in FIGURE 2, the container is assembled in tubular form. The top and bottom closure assemblies are in open position and the surfaces on which the pressure-sensitive adhesive is preapplied are shown by the shaded area. Container closure tab 18 and tabs 18a are folded along fold lines 17 and 17a and connected to side wall panel 13 and side closure flaps 23. Any convenient means may be employed for this connection such as taping, gluing, stitching, or stapling.

FIGURE 3 is a diagrammatic view looking down on the container through the partially closed top closure assembly viewing 'the inside of the closed bottom :closure assembly. The shaded areas show the surfaces upon which the pressure-sensitive adhesive is applied. Opposed end flaps 20 and 22 have been partially folded inwardly along fold lines 24 and 28 and 26 and 29, respectively. The end flaps are hingedly connected to the side flaps thus inward movement of the end flaps draws the side flaps into approximately edge-abutting relation thereby closing the container.

FIGURE 4 is a diagrammatic view of the inside of the bottom of the container with the closure flaps in closed position. This section is taken along section lines 4-4 of FIGURE 5. The inside of end flaps 20 and 22 may be seen in part. It should be noted that flaps 20 and 22 have received no preapplication of adhesive on the side facing the inside of the container. Also of note is that it is not necessary to preapply a pressure-sensitive adhesive to the inside, or the outside, of side flaps 21 and 23.

FIGURE 5 is a diagrammatic view of the container with the top and bottom closure assemblies in closed position.

Several pressure-sensitive adhesives, which adhere only to themselves or similar items, are on the market, any of which would serve the purpose for my invention. It has been found that a pressure-sensitive adhesive obtained from the American Latex Products Company, sold commercially as W-599, has given satisfactory results.

In accordance with the patent statutes, I have described the principles of construction and operation of my container; and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
