PATENTEUunv 30 IQYI SHEET 2 BF 3 TAPE ROLLS HOLDING AND DISPLAY BOX This invention relates to a display box or carton for holding a plurality of tape rolls for display.

In the specification and claims the term tape roll means various tapes such as pressure-sensitive adhesive tape, moisture-active tape (sometimes referred to as gum tape), solvent-active or nonadhesive tape or the like which is wound into a roll form. Typically, such tape is wound around a tubular core into a roll.

It has been a conventional practice that, when such rolls are placed on the market for sale in retail stores, each roll is packed in a paper box or metal can. However, there are drawbacks that the packing operation is difficult or troublesome, handling is not easy, it is impossible to inspect the packed roll from outside. Further, such package is not attractive from the display point of view.

Therefore, it is an object of this invention to provide selectively and readily openable and closeable carton for holding a plurality of tape rolls in such a manner that any desired tape roll (s) can be easily taken out or inserted in the carton by a very simple operation.

Another object of this invention is to provide a carton of the type mentioned just above which can hold a plurality of tape rolls with an attractive display effect.

Still another object of this invention is to provide a carton of the type mentioned above which can hold a plurality of tape rolls in such a manner that each roll is partly exposed out of the carton so that it is visible from outside for inspection and for effective display.

Another object of this invention is to provide a carton of the type mentioned above which is simple in the structure and easy to manufacture and assemble.

Further objects, advantages and features of this invention will be apparent from the following description.

These objects of this invention are accomplished according to the invention by providing a carton which comprises a front panel provided with a plurality of window openings arranged in series, a back panel provided with a plurality of window openings respectively corresponding with the openings in the front panel, a folding line provided on each of said panels along its lengthwise center and across the series of the window openings, a first sidewall connecting the front panel and back panel at one side, a second sidewall connecting the front panel and back panel at the other side, each of the front panel and back panel being adapted to be folded inwardly along the folding line so that when the front panel and back panel are so folded inwardly and toward each other the tape roll can be held in the adjacent window openings on the front and back panels.

Each opening is rectangular and has a length slightly longer than the tape roll diameter and has a width slightly larger than the width of the tape so that the tape roll can barely pass through the opening before the panel is folded. However, when the front (or back) panel is folded inwardly as mentioned above the tape roll can not pass through the window opening. As will be understood, the front panel, back panel, first sidewall and back sidewall together form an open-ended carton. When the carton is used for display or otherwise in an upright manner, it will be deemed to have an upper and lower end. Preferably, one of the sidewalls is provided at its lower end with an end flap to close the bottom opening of the carton after the both panels have been folded. Similarly, one of the sidewalls may be provided at its upper end with another end flap to close the upper opening of the carton after the both panels have been folded.

The invention will be explained in more detail by referring to the accompanying drawings wherein:

FIG. I is a front view of a carton embodying the present invention before closing both open ends;

FIG. 2 is a plan view of FIG. 1;

FIG. 3 is a perspective view of the carton;

FIG. 4 is a view showing the state in which the rear panel is fully folded together to lie one half over the other half and the front panel is not folded for another form of display position in which form the end panels are preferably omitted or removed;

FIG. 5 is a side view of the form of FIG. 4; and

FIG. 6 is a plan view of one developed cutout of the carton blank prior to being assembled into a carton of the invention.

The material for forming a carton of this invention may be paper (sheet or board) or any other suitable material such as synthetic resin sheet, for example, polypropylene, polyvinylchloride, etc. provided it is self supporting. Preferably, a single and integral sheet in a shape adapted to be assembled into a carton is stamped out from a single-sheet material. In the embodiment shown in the drawings, a sheet as shown in FIG. 6 is stamped out. Indicated with I is a front panel, 2 is a back panel, 3 is a first sidewall and 4 is a second sidewall. One of the sidewalls has a lower end flap at lower end, and one of the sidewalls has an upper end flap at the upper end. In the embodiment shown, the first sidewall 3 has a lower end flap 5 and the second sidewall 4 has an upper end flap 6. The end flaps 5 and 6 are provided respectively with

insertion lips

7 and 8 in the usual manner. Preferably, the upper end flap 6 is formed at one side with a suspender tab 9 having a hole 10. Along the longitudinal marginal of the back panel 2 there is provided a narrow side flap 11.

The front panel 1 is formed with a plurality of window openings 12 (there are five openings in the embodiment shown). Corresponding openings 13 are also formed in the back panel 2 as shown. Each opening is rectangular and has a length and width slightly larger respectively than the diameter and width of a tape roll to be held by the carton. Along the longitudinal centerline and across the series of the openings there is formed a folding line 14 on the front panel 1. A similar folding line 15 is also formed on the back panel 2. As shown the window openings on each panel are arranged in parallel and with a suitable space between adjacent openings. The openings 12 on the front panel 1 and the openings 13 on the back panel 2 are in symmetrical relationship with each other.

Indicated with the letters a, b, c, d, e, f, g, h and i are folding lines.

In assembling the above-mentioned sheet material into a carton of the invention, the various portions are folded inwardly along the folding lines a, b, c, d, e,f, g, h and i, and then the surface of the side flap 11 is bonded to the back surface of the second sidewall 4 along the longitudinal marginal by means of a paste, adhesive or the like (FIG. 3). The carton thus assembled is now ready for use.

In packing tape rolls in the carton, each tape roll T is inserted into the carton through the window opening. Then, the front panel 1 and back panel 2 are folded inwardly along the respective folding lines so that the tape T engages the

edges

16 and 17 of the

openings

12, 13 and cannot slip out from the openings. Then, the upper end flap 6 covers the upper open end of the carton and the lip 8 is inserted inside the upper end portion of the first sidewall 3. Similarly, the lower open end of the carton is covered by the lower end flap 5 and the lip 7 is inserted inside the lower end portion of the second sidewall 4. In this way the carton assembly is fixed with the tape rolls removably held therein. It will be understood that each end flap 5, 6 is of such a dimension that it will fit the open end of the carton in the state where the both longitudinal middle portions of panels I and 2 have been folded inwardly.

As will be understood, the first sidewall 3 and the second sidewall 4 are identical in dimension, and the front panel 1 and back panel 2 are identical in dimension. Preferably, the relationship of these walls and panels in respect of their widths is such that when the

panels

1 and 2 are folded inwardly the folding edge 18 of the front panel 1 and the folding edge 19 of the back panel 2 will abut or contact with each other (FIG. 2 and FIG. 3). In order to render the carton assembly more rigid it is preferable to releasably connect the edges 18 and 19 at the lower end and/or upper end by a suitable fastener 20 as shown in FIGS. 1, 2 and 3. However, the end flaps 5 and 6 also serve exceptionally well to releasably maintain the inwardly folded edges 18 and 19 in good adjacent relationship. The suspender 9 can be used to hang the carton with the tapes held therein for display. In this case the hole 10 is utilized to hook the suspender 10 on a nail or the like. Since the tapes are partly exposed out of the

window openings

12, 13 they are visible from outside.

When it is desired to take out any tape roll, both end flaps 5, 6 are pulled out and one or both

panels

1 and 2 is pulled back (unfolded) to the original plane form to disengage the edges 16 and/or 17 from the tape The tape is now free to he slipped out from the window openings. if desired, the taken-out tape roll may be replaced with a new one in this state of carton. Then the unfolded panel (s) is again folded inwardly to retain the tape roll and thereafter the end flaps are again returned to the ordinary closure position If desired, as shown in FIGS. 4 and 5, it would be possible to fully fold the back panel 2 so that its one half would he on the other half, while the front panel l is not folded. Preferably, the folded edge of the back panel 2 is fixed to the front panel it along the latters folding lines by means of a releasable fastener 20. The carton in this state may be placed horizontally for display as shown with the second sidewall 4 forming the bottom and the first sidewall 3 forming the back support. ln this state, the tape roll can be freely taken out or inserted in the window opening 12 without disassembly or opening and closing of end flaps. Further, in this case, the end flaps 5 and 6 are not necessary and therefore may be removed if desired.
