INVENTOR VINCENT R. PANTALONE ATTORNEYS Sept. 6, 1966 v. R. PANTALONEI CURVED FRONT PANEL DISPLAY CARTON 4 Sheets-Sheet Filed June 11, 196

INVENTOR VINCENT R. PANTALONE ATTORNEYS United States Patent I York Filed June 11, 1964, Ser. No. 374,450 8 Claims. (Cl. 206-4519) This invention relates to display cartons and particularly to a carton or box having one or more openings in the front face or wall and having within it a central display area with provision for supporting an article for example a glass bottle or other frangible container, in such a way as to make the article clearly visible.

The purposes of the invention are to provide a display carton which is somewhat larger than the product or container therein but which is so constructed that the size of the container can be clearly seen without opening the package thereby avoiding any deception in the packaging; to provide a carton which is of novel appearance and shape and yet can be marketed in the form of a collapsible blank that can be readily set up by the user; and to provide for the protection of the frangible contents against mechanical injury in handling.

In accordance with the invention a box or carton of this type is made from a one-piece blank arranged with conventional panels and having flap and end closure extensions, and also having an extension hinged to one end of the rear wall which can be folded against the inner surface of the rear wall, such extension being provided with wing members hinged thereto on its opposite sides and projecting forwardly and angularly to contact with the inner surfaces of the side walls to form the display area. The front and rear wall panels are connected together by side panels which have told or score lines extending centrally from end to end and also through the top and bottom closure flaps. The rear wall panel is rectangular and joined to the side panels by straight parallel fold lines, whereas the front wall panel is joined to the side panels by outwardly convex symmetrical fold lines, advantageously cut-score lines.

With this construction the front and rear wall panels can be folded into contact with each other by folding the side panels along their lengthwise score lines and when the thus collapsed blank is set up to form the carton the connections of the front wall panel to the side wall panels along the convex fold lines will cause the front wall panel to become dished or concave from top to bottom, the rear wall panel however remaining fiat.

The invention will be described in greater detail following the description of the accompanying drawings which show a carton constructed to display a bottle of glass or other breakable material. In these drawings:

FIG. 1 is a plan view showing the outline of the blank from which the carton is made, the blank being viewed from its inner side and its opposite surface being printed, if desired, in one or more colors;

FIG. 9 is a view of the set up carton in front elevation with both the lower and upper portions broken away and shown in section;

FIG. 10 is a transverse section taken on line 10-10 of FIG. 9; and

FIG. 11 is a central vertical section taken on line 11 of FIGS. 9 and 10.

Referring first to FIG. 8 which shows the completely set up carton or box 1 of the present invention, it has a fiat or planar rear wall 2 and a front wall 3 which is concave from end to end, that is from top to bottom. The sides of the rear wall 2 are parallel to one another being rectangular in form whereas the sides of the front wall 3 are convex as indicated in FIG. 8 and also shown in FIG. 9. Also the side walls are straight and parallel at the back where they join the rectangular rear wall 2, but are convex at the front where they join the concave front wall 3. In this way an attractive carton or package is provided which has a unique and distinctive shape and appearance and at the same time provides a display container for an article such as a bottle, or other product which requires protection against mechanical damage during shipment and handling.

The carton 1 is formed from a blank shown in plan view in FIG. 1 and indicated generally by reference numeral 4. Blank 4 has a rectangular rear wall panel member 5 which is bounded on its side and bottom edges by

score lines

6, 7 and 8 respectively and which forms the rear wall 2 of the carton. The blank also has a front wall panel 9 forming front Wall 3 of the carton. Panel 9 is bounded on its opposite sides by outwardly convex

cut score lines

10 and 11 which intersect straight and

parallel score lines

12 and 13 at the top and bottom respectively.

The two side wall panels are similar, panel 14 being bounded by straight score line 6 and convex cut score line 10. The opposite side wall panel 15 is bounded by cut score line 11 and the outer edge 16 which is straight and parallel with

score lines

6 and 7. Each of the

side panels

14 and 15 is divided by means of a central score line indicated at 17 and 18 respectively. These two score lines divide the two side Walls into substantially equal width sections,

inner sections

14a and 15a and

outer sections

14b and 15b.

At the upper ends of

side walls

14 and 15 there are

top closure flaps

19 and 20 respectively, and at the lower ends there are

bottom closure flaps

21 and 22. The

central score lines

17 and 18 extend through these top and bottom closure flaps dividing them also into

sections

19a and 19b, 20a and 20b, and 21a and 21b, 22a and 22b.

A front wall top closure flap 23 is hinged thereto along score line 12, and a bottom closure flap 24 is hinged along the lower score line 13.

Closure flaps

23 and 24 are provided at their outer ends respectively with tuck-in

tabs

25 and 26. Front wall panel 9 is provided with lower and

upper windows

27 and 28 in the form of generally crescent-shaped openings which will be referred to later on. The rear panel 5 of the blank has projecting from its lower edge an extension member indicated generally by reference numeral 29. This extension is substantially narrower than panel 5 but has a base portion 30 of the same width as this panel and which is connected thereto along score line 8, thus giving to extension 29 a general T-shape. The opposite sides of the upright portion of the T-shaped extension 29 are alternatively creased and perforated along

lines

31 and 32 and

wing portions

33 and 34 are connected thereby to the extension.

Extension 29 is provided with an enlarged head portion 35 connected thereto along score line 36. Centrally of this head portion there is a cross score line 37 which 3 divides the head portion into halves. The outer half 38 has glue applied to it and is folded along line 37 and glued to the inner half as a preliminary step in folding the blank, thereby doubling the thickness and strength of the head portion which is provided with an aperture 39 (FIG. 2) for suspending the carton as will appear later.

The left-hand edge of rear panel 5 is provided with a glue flap 40 which is hinged thereto along score line 7, the glue being applied to its opposite face as viewed in FIG. 1.

The lower

closure flap sections

21a and 22a at the bottom of the blank are provided with

extension strips

41 and 42 respectively. These are hinged to the closure flap sections along

score lines

43 and 44, and each is divided into 3 sections, an outer section 45, an intermediate section 46 and an inner section 47.

It is important to ship the carton in a condition in which it is collapsed to make it as thin as possible so that. the collapsed blanks may be shipped in compact packages to the user. The completely collapsed carton or carton blank is shown face up in FIG. 4 and indicated generally by reference numeral 48. In order to fold the blank 4 of FIG. 1 to this condition, after the preliminary step of folding the glued outer half 38 of head portion 35 on to the lower half as previously mentioned, the next step is to fold extension 29 about score line 8 through an angle of 180 and into fiat contact with the inner surface of rear panel 5. This is shown in FIG. 2 where it will be seen that the right-hand wing 33 overlies outer panel section 14b of the carton side panel but its edge 49 is spaced from the central fold line or crease 14. Also the lefthand wing 34 overlies glue flap 40, and its edge 59 may be substantially in alignment with the edge 51 of this glue flap.

In addition to this folding operation, the two

extension strips

41 and 42 are folded about

score lines

43 and 44 respectively. Prior to such folding however, a pad glue operation applies glue to the rectangular areas 51' and 51" on the inner surfaces of the respective inner sections 14a and a of the carton side walls. Consequently when the

strip extensions

41 and 42 are folded their outer sections 45 are glued to these inner side wall sections at the

glue areas

51 and 51". The blank 4 with the folding operations just mentioned completed is shown in FIG. 2.

The next folding operation is to turn the rear wall 5 about fold line 17 through an angle of 180 thereby bringing the extension 29 and its

wings

33 and 34 into contact with the inner surface of front wall 9 as shown in FIG. 3. The surface of glue tab 40 to which the glue has been applied now faces upwardly, and the outer section 15b of the carton side wall .15 is folded in the direction of the arrow shown in FIG. 3 about score line 18 and permanently glued to glue tab 40. Inasmuch as glue tab 40 is narrower than side wall section a, the edge of glue tab 40 and the edge 50 of wing 34, which are in alignment with one another, are spaced from score line 18. Hence the

edges

49 and 50 of

wing members

33 and 34 are also spaced from score line 18. This completes the formation of the collapsed blank 48 except that in FIG. 4, it has been turned face up, it being understood that the front wall 9 and the rear wall 5 are pressed as close together as possible so that the collapsed blank will occupy a minimum space.

The collapsed carton blank 48 is set up or squared up to form the carton It of FIG. 8 in the following manner:

Forces are applied in opposite directions as shown by the arrows in FIG. 5 to the side edges of blank 48 formed by the opposite central score lines or fold

lines

17 and 18, either by the fingers or by the mechanism of an automatic setting-up machine. Such pressure, due to the angularity even in the fiat condition of FIG. 4 of the

sidewall sections

14a, 14b and 15a, 15b causes the rear and

front wall panels

5 and 9 respectively to be forced apart as shown in FIG. 5. Continued application of such pressure brings the blank to the position shown in FIG. 6, this view being a section taken above the center of the carton and along the same line 55 as FIG. 5. During this squeezing action on the opposite sides of the carton blank the front wall panel 9 is, by the convex

cut score lines

10 and 11 which connect it to the front side wall sections 19a and 20a respectively, forced into a concave position such as shown in FIGS. 8 and 11 and also in FIGS. 6 and 10. Inasmuch as FIG. 4 shows the collapsed blank face up, that is, with the front wall uppermost, the joint between glue flap 40 and the outer side wall section 15b is at the left as may be seen from FIG. 5, hence

side wall sections

14a and 14b are at the right. When the carton is completely set up as shown in FIGS. 6, 9, 10 and 11, thus bending the front wall panel 9 to concave position, the central portion 52 of this wall between the

arcuate windows

27 and 28 remains flat as shown particularly in FIGS. 6, 10 and 11 inasmuch as there are no forces tending to bend the upper edges of this central portion. How ever, the

portions

53 and 54, below and above the two windows are displaced forwardly of the central portion 52. Also the lower curved edge 55 of the lower arcuate window 27 curves outwardly in front of the central portion 52 as shown in FIGS. 6 and 10. The same is true of the upper edge 56 of the upper window 28 (see FIG. 11).

After pressure has been applied to the side edges, that is, the

central fold lines

17 and 18, to square up the main body of the carton, the next step is the folding of the bottom closure flaps. The side closure flaps 21 and 22 are closed first. The inner and outer sections of each being closed as a unit, that is, folded to horizontal position.

From FIGS. 1 and 2 it will be remembered that extension strips 41 and 42 were folded against the inner surfaces of the inner

side panel sections

14a and 15a, and their upper end portions 45 as viewed in FIG. 2 glued thereto at 51 and 51". Therefore when the bottom closure flaps 21 and 22, including their

inner sections

21a and 22a are folded upwardly as shown in FIG. 7 the parts swing as parallelograms portions 46 on each side moving parallel with the

flap sections

21a and 220. When the latter have been raised to horizontal position, the sections 46 will also be horizontal as shown in FIGS. 9 and 11.

Together these members constitute a platform to support the contents of the carton such for example as the bottle 57 shown in the dot-and-dash outline. Because of the curvature of the convex front wall 9, the

portions

47, 46 and 45 of the extension strips are cut back as indicated at 58 in FIG. 11. After the folding of extension strips 41 and 42 just described the front wall bottom flap 24 is folded to horizontal position outside of the side closure flaps 21 and 22, and its tuck-in tab 26 is inserted in position adjacent the rear of the carton as shown in FIG. 11. In squaring up the collapsed blank 48 in the manner previously described the unfolding of the

side wall sections

14a, 14b, and 15a, 15b from the position of FIG. 4 to the position of FIGS. 6-11, the two

wing members

33 and 34 are swung outwardly about their

hinge lines

31 and 32 so that their

forward edges

49 and 50 bear against the respective

side wall sections

15b and 14b in proximity to the

longitudinal fold lines

17 and 18. Thus as shown more particularly in FIG. 10 these surfaces form with the front wall of the carton a central display area or pocket to receive the display articles, such as the bottle 57. As shown in FIG. 10 the bottle is cushioned at the front against the flat central portion 52, the entire front wall being resilient on account of its concave form. It is cushioned at the rear by the central portions of

wings

33 and 34 respectively.

Wing members

33 and 34 are beveled as indicated at 58 at their lower corners so as to clear the platform members 46. At their

upper ends wings

33 and 34 have tapering extensions or ears 59 extending above the

hinge connections

31 and 32 to the extension member 29. The inner surfaces of these extensions have sloping edges 60 which when bent forward are approximately parallel with similar sloping edges 61 which bound the lower sides of head portion 35 when the head portion is in position within the carton as shown in FIGS. 9 and 11.

Before closing the top of the carton head portion 35 is bent to .a forward position as shown in FIG. 11 at an angle of nearly 45 to the horizontal, and with the upper end of the head portion received at the front corner of the box adjacent the hinge of front wall top flap 23. This flap is then bent forwardly and downwardly to 'hori- Zontal position and its tuck-in flap 25 inserted adjacent the rear panel 5.

The display area or pocket containing the contents such as bottle 57 is bounded at the bottom by the supporting platform numbers 46, at the sides by

wing members

33 and 34 and at the top by the sloping surface of head member 35. The bottom of the bottle 57 is visible through the lower window area 27, and the top of the bottle through the upper window area 28 so the fact that the bottle is of smaller dimensions than the display carton will be apparent to the purchaser.

Should it be desirable for the carton to be suspended as for example on a display rack, the front top flap 23 may be raised and head portion 35 swung to upright position shown in dot and dash lines in FIG. 11, and the top flap returned to its horizontal position with tuck-in flap 26 pressed against the surface of the head member to hold it in upright position. The suspending aperture 39 in the head member will then be above the top of the carton.
