ATTORNEY United States Patent O U.S. 01. 206-4534 9 Claims ABSTRACT OF THE DISCLOSURE A single or double windowed display container is presented which is formed from an integral blank of paperboard and which includes a tray-like portion and a backing portion secured together to form a product retaining package.

BRIEF SUMMARY OF INVENTION This invention relates generally to a display container for the packaging of soft good products for sale.

More specifically, the invention relates to a paperboard container which is suitable for packaging soft good products or food products where the sales appeal is promoted due to the visual advantages attendant with the windowed nature of the container. The invention also affords a hangup feature for rack merchandising of the packaged products.

Paperboard containers having windows of transparent synthetic plastic sheet material are employed widely for displaying their contents to the prospective purchaser and for achieving attractive package styling. However, most window containers presently on the marketplace use thin, highly flexible film as a cover for the window sheet material, and accordingly the window apertures in the paperboard sheet material have generally been small when it was desired to obtain a relatively high-strength and durable container. There is a need therefore, for a strong and attractive display container with large see-through windows to attract maximum customer attention. Further, because soft goods in particular are generally sold as singular items, the container must also be inexpensive and relatively easy to fill and close. By using a container which is relatively easy to close, the need for complicated packaging machinery or high labor costs is avoided. In addition, the container must be capable of being shipped in a flattened and sometimes partially assembled condition to minimize costs of handling and shipping a supply of containers to the packager. Finally, in order to provide the most esthetically attractive package, it is desirable to form the container with extended areas at one or more sides for graphic display material.

Applicant, with the container of this invention satisfies the above stated requirements and presents a novel container for displaying for sale soft goods or the like in a tamper proof package. The sort of soft goods for which this invention was developed relates particularly to items of womens apparel or lingerie, although it should be obvious that many different kinds of goods including foodstuffs and hardware could be conveniently packaged in the novel container. The container takes the form of a fiat, cut and scored integral blank of paperboard which is readily assembled either by hand or on machinery to provide an attractive compact display. At least three specific embodiments of the container are disclosed herein including one embodiment showing a single window configuration.

It is well known that the exterior appearance of a display container plays an important role in the marketability of the packaged product. With applicants container, the completely sealed product retains its clean and pre-arranged condition when displayed for sale. In addi- 3,498,446 Patented Mar. 3, 1970 tion, with the novel window construction on each face of the double windowed container, the prospective purchaser can easily determine exactly what is offered for sale with no hidden areas. In the double Windowed configuration, the window on the back face of the container is preferably full sized, i.e., it occupies the entire rear wall of the product area. Whereas the front window preferably is formed slightly smaller with a small area surrounding or framing the window for graphic display. Since only one side of the paperboard is in view when the container is assembled, the blank requires only one pass through the printing press obviating the need for printing both sides. The single window configuration retains its window'in the front wall only, but still has the same amount of graphic display space as the double windowed embodiment.

A unique glue flap arrangement on all four sides of the package provides the graphic display areas and plays an important role in forming the tray-like outer front panel which houses the product. The package further includes more or less conventional tabs and slots or glued flaps at the four corners of the tray-like front portion to complete the closure. The total effect of the raised and reduced in size front tray-like portion, when glued to the flat, enlarged back portion, is to achieve the framed appearance of the product which certainly helps promote the saleability of the packaged item.

The cost of the display container of this invention is quite competitive with presently available packages for soft goods and it can readily be closed and sealed without the need for expensive machinery. The outer flaps are preferably glued and the corner closure tabs are preferably designed so that the package may be closed and filled on lock forming equipment such as Kliklok machinery, Memco equipment, and Packaging Machinery Traylock. In addition other machinery may be used to fill and seal the package including Forming equipment made by Brightwood, Head Seal, Palmer and Peters. However, as pointed out hereinbefore the package could just as readily be closed by hand. In addition to the advantages and features discussed above, numerous other advantages and features will be apparent with reference to the drawing which forms a part of this specification.

DETAILED DESCRIPTION Referring now to the drawing in detail and particularly to FIGURE 1, there is illustrated a flat blank of paperboard preferably coated on one side from which the display container of this invention may be folded. As shown in FIGURE 1, the blank includes a rectangular back panel 10 and a rectangular front panel 20. The back panel 10 includes a full sized cut-out 11 which forms the rear window of the preferred double window container. A single rectangular sheet of transparent plastic film designated 12 is placed against and secured to the back panel 10 so as to overlap the sides of the window 11. The surface of the blank to which the adhesive is applied for securing the plastic film 12 to the back panel 10 is the inner surface of the package in its finished state. The plastic film 12 is secured on all four sides so as to completely seal the inside of the package from dust and provide a tamper proof container. A glue flap 15 is hingedly attached along a cutscored fold line 14 to one of the side edges of the back panel 10. Fold line 14 is formed by a die which does more than simply score the board. One of the face surfaces of the board is actually out so that the glue flap 15 can more readily fold through an angle of 180 degrees and be secured to the inner face of the blank. In addition, back panel also has a rod engaging slot 13 in the upper portion thereof which is cut out of the blank for use in suspending the completed package over a rod projecting horizontally from a wall, as in point of purchase retail display and merchandising operations. The cut out 13 cooperates with a similar cut out 37 in front panel 20 when the package is filled and closed to complete the display.

As shown in FIGURE 1, glue panel 15 is joined at its free edge along cut-score line 16 to one of the side walls '45 of the front panel 20. Glue panel 15 is shaped as illustrated so that in the closed condition its outer

free ends

47, 48 will cooperate with the outer free ends 49, 50 of the

end glue flaps

35 and 36 respectively. This shape is choosen for example only, because other shapes have been found to work equally well in other embodiments. The side wall 45 has slotted

closure tabs

21, 22 at each end thereof which are hingedly connected to the side wall 45 along scored lines 19 and 18. The main panel portion of the front panel 20 is shown attached to the side wall 45 along the cut-score line 17. A second window 43 is cut out of the blank in the main portion of front panel 20 and covered with a film of plastic 44 in the same manner as described hereinbefore for the back panel window 11. As will be noted from the drawing, the front window 43 is nearly as large as the back window 11, but is not quite full size. The front window is made slightly smaller for both structural considerations, and, also, a desire :to leave some space around the second Window for graphic display. The finished package is also rendered a great deal stronger by not making the window 43 full sized.

Attached to the ends of the main portion of front panel 20 along scored

lines

31, 32 respectively are a pair of

end walls

29, 30. At the opposite side edge of the main portion of front panel 20, a second side wall 46 is hingedly attached along cut-score line 38. The side wall 46, like the opposite side wall 45 has a second pair of

closure flaps

26, 28 attached at each end thereof along scored lines 40', 39.

In the assembled condition of front wall panel 20', the

respective closure tabs

21, 22 and 26, 28 are arranged to intercept and become engaged with

cooperating slits

24, 23, 25 and 27. The slits are strategically located in the end walls 29, of the main portion of front wall panel 20 so that the closure flaps 21, 22, 26 and 28 may be inserted therein either by hand or on packaging machinery. With the front wall panel 20 so assembled it takes on the appearance of an inverted tray having a peripheral lip. The remaining portions of the front wall panel 20 are the glue flaps 42, and 36. Glue flap 42 is joined along cut-score line 41 to the side wall 46 and the glue flaps 35, 36 are attached along cut-

score lines

33, 34 to the

end walls

29, 30. The free end edges 53, 54 of glue flap 42 are shaped in such a manner that they cooperate in the assembled and secured condition with the free end edges 51, 52 of the end glue flaps 35, 36 respectively.

It is apparent from FIGURE 3 that the back panel 10 must be large enough to accommodate :the glue flaps 15, 35, 36 and 42 of the front panel 20. When the display container is assembled, the inner surfaces of back panel 10 are ultimately secured to the inner surfaces of front panel 20 so that only the outer surfaces of the display container come into view. This same requirement also applies for the container blank modifications of FIGURES 4 and 5.

The manner in which the foregoing blank structure is folded and glued to complete the fabrication of a package will now be described. The blank may be shipped folded flat along hinge line 14 in either a completely disassembled or partially glued condition. If partially glued, the glue flaps 15 and 42 would be positioned as shown in FIGURE 2 with end glue flaps 35, 36 and end

walls

29, 30 unassembled. If not preglued, the

glue

15, 42 would be first glued then the product would be placed between the window portions 11, 43 of back panel 10' and front panel 20'. After this step, the closure flaps 21, 22, 26, 28 would be manipulated mechanically or by hand to complete the assembly of the front panel 20. Subsequently the end glue flaps 35, 36 would be glued to the inner face of back panel 10 to complete the package.

Alternatively, the front portion 20 of the blank could be formed first with the closure flaps 21, 22, 26, 28 being inserted in

slits

24, 23, 27, 25. Next the product would be inserted in the tray-like portion and finally the glue flaps 15, 35, 36 and 42 would be sealed to complete the package.

Turning now to the FIGURE 4 modification, there is disclosed a container blank having the same general configuration as that of FIGURE 1. Accordingly, for the sake of clarity, like reference numerals have been applied to like parts of the two Figures.

The FIGURE 4 embodiment includes a back panel 10 of the same shape as that of FIGURE 1 except for the shape of the glue 15. It was found that the specific shape of the flap 15 of FIGURE 1 was not necessary to the proper functioning of the inventive container except for esthetic considerations. The blank of FIGURE 4 is accordingly easier to fabricate and uses less paperboard.

The only other distinguishing feature of the FIGURE 4 embodiment when compared with the FIGURE 1 disclosure is in the use of glued

flaps

21, 22 and 26, 28 as the closure flaps of the front tray-like portion of the container. This versatility, wherein either tabs and slots (FIGURE 1) or glued flaps FIGURE 4), could be used, permits the container to be adaptable to the different kinds of form-fill-seal machines.

Another characteristic shared by the FIGURE 1 and FIGURE 4 embodiments is that each shows the front and

back panels

10, 20 as being joined to one another along a fold line at their respective sides. This particular arrangement is not absolutely required as will be noted with reference now to FIGURE 5.

The FIGURE 5 embodiment shows the back panel 10 as being joined to the front panel 20 along a fold line 14 located at the respective ends of the two panels. FIGURE 5 shows the fold line jointure as being at the top ends of the two panels where the hanging

slots

13 and 37 are located, however, the jointure could just as readily be made at the lower end. This embodiment also shows one example of a single window configuration wherein the window 11 is only located in the bottom panel 10. The top panel, or tray-like portion 20 of the container is formed from a series of panels and flaps which correspond closely with similar panels and flaps used in the FIGURE 1 embodiment.

Referring particularly to FIGURE 5, the top panel 10 includes a pair of

glue fiaps

35, 36 attached respectively to the

end walls

29, 30 along

fold lines

33, 34. The glue flaps 35, 36 are of a U-shaped configuration which oppose one another and are formed by cut-

lines

56, 57 and 58, 59 located at the ends of

end walls

29 and 30, and by cut-lines 60, 62 and 61, 73 located at the ends of the

tray side walls

46 and 45 respectively. This arrangement is substantially different from that used in the FIGURES l and 4 embodiments, however, the inventive concept is retained in that a tray-like panel 20 is ultimately secured to a back panel 10 to form the container.

The tray-like panel 20 is completed with the addition of side glue flaps 15 and 42 which are joined by

fold lines

16 and 41 to the side panels 45' and 46. Each of the glue flaps 15, 35, 36 and 42 are sized so as to fit within the confines of the back panel when the two panels are secured together.

In the preferred manner for sealing the package, glue is applied to the inside face of the back panel 10 in the form of a hot melt adhesive and a similar glue is applied to the inside surface of the panels formed in glue flaps 35, 36 by cut-lines 56 through 63. The glue on the last mentioned panels allows the tray portion to be set-up before filling by breaking the panel along fold lines 16-17, 38-41 and 31-33 and 32-34, and then securing the glue panels to the outer face of the glue flaps and 42. Alternatively, other steps could be used to set-up the container of FIGURE 5 without departing from the scope of the invention.

It may thus be seen that applicant has invented a novel display container for point of purchase use wherein the components of the invention consist of two panels one flat and the other resembling an inverted tray which are secured together to present a tamper proof package. The different embodiments of the invention include containers with one and two windows and include containers which are hinged at their sides or at their ends.

Further, various interchangeable means have been disclosed for securing the container together either on locking machinery or forming machinery.

The versatility of the inventive display container should be obvious from the above description, and one skilled in the art could easily derive additional uses and configurations without departing from the scope of the invention. Only the preferred embodiments have been shown and described in detail.
