5 Claims. (Cl. 229 -87) This invention relatesto an improvement in packages and deals particularly with a package useful in containing sliced bacon or 'a similar product.

Various types of packages have been produced for The rangement, the longitudinal edges of the package may be thinner than the remainder of the package as the ends strips 'of the series are not built up in thicknessby super- It has been found that by providing a package folder having end walls which'taper in thickness toward their juncture with the sides of the package, the desired result may be obtained. Such an arrangement-is provided by forming the end walls with substantially parallel fold lines throughout the major portion of their length and by providing converging fold lines connecting the ends of these fold lines with the juncture between the end walls and the sides of the package. As a result a package is provided which is relativey thin or which may have no side walls along the longitudinal edges of the package and yet which is relatively thick throughout the central part of the package. A further feature of the preferred form of construction of the invention resides in the provision of a package having substantially flat upper and lower surfaces and having tapering edge portions which taper in thickness to the marginal longitudinal edges of the package. As a result. the packages may be paced one upon the other and will stack eifectively for storage'o'r for display but at the same time the package is provided with the proper cross-sectional shape.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the fol'owing specification and claims.

In the drawings forming a part of the specification:

Figure 1 is a perspective view of a bacon package showing the new construction.

Figure 2 is a'top plan view of the package illustrated in Figure 1.

Figure 3 is an elevational view of the package shown in Figures 1 and 2.

Figure 4 is a diagrammatic view of the blank from which the package is formed.

Figure 5' is a diagrammatic view of a slightly different form of blank from that illustrated inFigure 4-.

Figure 6 is a perspective view of a modified form of package in which the bacon is entirely enclosed.

Figure 7 is a plan view of the package shown in Figure 6- after thepackage has-been sealed.

Figure8 is a diagrammatic view of the blank from which the package of Figures 6 and 7 is "formed.

Bacon packages may be of several types. Some such imposed layers of bacon. Thus it is the purpose of'the present invention to provide a package where the longitudinal edges are thinner than the central portions of the package.

fine

packages include a bottom-panel, a pair of end panels which fold over the bottompanel Ito overlie theends of package construction which. entirely enc'oses the bacon Is'trips. This type of package may be providedvwith a window through which portions of the overlapped strips are visible if it is so desired. The present invention is designed to form either of these types of packages, v it being only'necessary to modify thegshape and form of the various closing flaps to accomplish .eitherresults.

In'the .form of construction illustrated in Figures .1

to 4 of the "drawings, the bottom panel 10 is foldably connected along a fold line 11 to a cover flap or panel '12. vThe ends of the bottom panel 10 are foldably connected-to

end wall panels

13 and 14. The fold lines connecting the bottom panel to the end wall panels is not a straight foldline. In thearrangement illustrated in Figure 4 of the drawings, the fold lines connecting the bottom panel tothe'end wal panels include

parallel fold lines

15 and 16 respectively which extend the major part of the distance between the free edge 17 of the bottom panel 10 and thefoldededge 11 thereof. Anangularly inclined foldline 19extends from one end of the 'foldlinelSt'o the freeedge'17and a similarly inclined 'fold ine 20 forms an extension of the. foldline 15 and extending to the juncture between the bottom panel 10 and the fold line 11.

The fold line 16 also extends the major-portion of the width ofthe bottom panel 10 and one end of this'fold line is provided with'an angular continuation 22 which extends to the free'edge 17 at the panel lit-and includes an angular extension 23 which extends from the'fold line 16 to the juncture betweenthe panel 10 and'the cover panel 12.

The end wall 13 is defined by a fold line 24 which extends parallel to and spaced from the fold line '15. The fold line 24 is coextensive with the fold line '15 and the ends of this fold line 24 are connected by angularly inclined extensions 25 and '26 to the' outer ends of'the fold line e'xtensions19 and 20. In other words the

fold'lines

19 and 25 diverge apart from the marginal edge :17 of the bottom panel to "the spaced fold lines '15 and 24. Similarly the fold lines 20'and 26 diverge apart from the fold line 11 to the ends of the fold'lines 15 and 24. In other words in this form of construction, the end wal 13'is generally hexagonal in shape.

The end wall 14 is shaped similarly to the end Wall 13. The end wall 14 is connected by a fold line 27 "to the top cover flap or panel 29. The fold line 27 is parallel to the fo'd line 16 and coextensive therewith. The ends of the fold line 27 areconnected by angularly inclined extensions 30 and 31m the panel edge 17 and the panel edge 11 respectively. Thus the end wall l-4 is generally hexagonal in shape a'though the length of the end walls are much greater than the height thereof.

The fold line' 24 with its extensions 25 and 2 6-foldably connect the end wall 13 to a top coverflap or panel 32*. Both the top panel 32 and the top panel 29 arepro vided with looking

slits

33 and 34 respectively by means at which the top cover flaps or

panels

32 and 29 ma be connected to the cover panel 12. g

When the package A is us'edthestr'ips of baconare placed upon the bottom panel 10 with the longitudinal edges in overlapping relation and with theends ofthe strips between the foldlines-15 and 16. Thepanelier flap 12 is then foldedab'outits fold lineal-dastoioverlie one orniore of the overlappedjstrips of bacon. Tins-flap thus normally conceals the major portion of the last strip of bacon of the series whlch would otherwise be exposed in its entirety. The

end walls

13 and 14 are then bent upwardly in right angular relation to the bottom panel 10. This action causes the bottom panel 10 to flex upwardly near the

edges

17 and 11 of the bottom panel to follow the confirmation of the fold line 15 and its

extensions

19 and 20.

The

top flaps

32 and 29 are the next folded downwardly to overlie the ends of the strips of bacon. During this folding operation, the ends of the

flaps

32 and 29 which are in alignment with the

edges

17 and 11 of "the bottom panel 10 also fiex downwardly to follow the confirmation of the fold line 24 and its

extensions

25 and 26 and the confirmation of the fold line 27 and its extensions 30 and 31. As a result, when viewed from the end, the package is generally hexagonal in sh pe.

Because of the irregular width of the

end panels

13 and 14, the resulting folded package is longer along its longitudinal edges than through the center portion of the package. In other words, the

end walls

13 and 14 also flex from the ends of the parallel fold line portions to the point where the fold line extensions converge together. As a result the package is not entirely rectangular in plan after it has been folded. However, the package may be overw-rapped with a rectangular sheet of transparent material such as 35 as the increase in length along the longitudinal edges of the packages compensates for the increase in height of the end walls of the shorter intermediate portion of the package. During the folding of the

top flaps

32 and 29, the locking cuts 33 and 34 are engaged with the marginal edge of the panel 12 to hold the folder in close position prior to the overwrapping operation. Actually, the overwrapping of the package is optional but is usually done to protect the carton contents. Alternatively, a covering sheet may be adhered to the bottom panel 10 and to project therefrom in a direction opposite the projection of the panel 12 and this covering sheet may be folded to overlie the bacon before the various fiaps are folded into covering position.

In Figure of the drawings I disclosed a slightly modified form of construction which does not have many of the advantages described in conjunctionwith the package A but which forms a package of unusual appearance. The package B illustrated in Figure 5 of the drawings includes a bottom panel 36 which is foldably connected along one longitudinal edge by a fold line 37 to a cover or side panel 39. The ends of the bottom panel 36 are connected along

arcuate fold lines

40 and 41 to end

walls

42 and 43 respectively. The center of arcuation of the fold lines 40 and 41 is externally of the bottom panel 36 so that the ends of the bottom panel are concave.

The

end walls

42 and 43 are connected along second

arcuate fold lines

44 and 45,to cover

panels

46 and 47 respectively. The

foldlines

44 and 45 are arcuate in a direction opposite to the arcuation of the fold lines 40 and 41.so that the

end walls

42 and 43 are relatively .thick at a point midway between the free edge 49 of the bottom panel and the fold line 37. These

end walls

42 and 43 taper to a minimum height at the ends so that the lfold lines converge together at each end of the end we] s.

This arrangement has the disadvantage that when the package is folded, the bottom panel 36 as well as the

top panels

46 and 47 are bowed downwardly and up wardly respectively resulting in a package which is continuously rounded from one .edge to the other. As a result of this arrangement, the packages will not stack efiectively and therefor packages of this type are not entirely the equivalent of the package A.

g In Figures 6, 7, 8, of the drawings I disclosed a modified form of package, this package being indicated in general by the letter C. As is indicated in Figure 8 of thedrawings, the blank from which the package C" is made is generally rectangular in form. It includes a bottom panel 50 which is foldably connectedalong its longitudinal edges by

fold lines

51 and 52 to generally triangular closing flaps 53 and 54 respectively. The ends of the bottom panel 50 are foldably connected to end

walls

55 and 56 by parallel fold lines 57 and 59 which extend the major portion of the width of the bottom panel and are provided with angularly inclined extensions connecting the ends of these fold lines to the side edges of the bottom panel. Fold

line extensions

60 and 61 connect the ends of the fold line 57 with the

sides

51 and 52 of the bottom panel 50 while similar fold line extensions 62 and 63 connect the ends of the fold line 59 with the bottom panel edges 51 and 52. The various fold line extensions incline outwardly from the center of the bottom panel 51 so that the fold lines 57 and 59 are closer together than are the ends of the fold line extensions.

The

end walls

55 and 56 are fodably connected to closing

flaps

64 and 65 which are generally triangular in shape. The fold lines connecting the end walls to the

flaps

64 and 65 include parallel

fold line portions

66 and 67 which'are connected by fold line extensions to the side edges of the bottom panel 50. Fold

line extensions

69 and 70 connect the ends of the fold line 66 to a juncture with the fold lines 51 and 52 while

fold line extensions

71 and 72 connect the ends of the fold line 67 to a juncture with the fold lines 51 and 52. As a result of this arrangement, the

end walls

55 and 56 are generally hexagonal in shape and the ends of end walls are of relatively no height while the main portions of these end walls are of sufiicient height to contain the strips of bacon within the closed package.

As is indicated in the drawings, the

triangular flaps

53 and 54 are connected to the fold line 51 by generally parallel end edges 73 and the closing flaps 64 and 65 are also connected to the ends of the

side walls

55 and 56 by generally parallel end portions 74. This arrangement is provided so that the various flaps will overlap when folded into position to enclose the folder contents.

In the particular arrangement illustrated, a window opening 75 is cut in the center of the bottom panel 50 and a generally rectangular transparent sheet 76 is adhered to the bottom panel 50 particularly around the window opening 70 as by the adhesive 77. If no package lining is required, the transparent covering 76 may extend only over the window opening 75 to slightly overlap the marginal edges of the bottom panel. However, if a package liner is desired, the transparent sheet 76 is practically coextensive with the blank from which the package is placed noon the bottom panel 50 between the fold lines 57 and 59, and the

end walls

55 and 56 are folded upwardly into right angular relation with the bottom panel.

This folding causes the longitudinal edges of the bottom panel to fold upwardly to some extent to follow the contour of the

fold line extensions

60 and 61 at one end of the package and the fold lines 62 and 63 at the other end thereof. The

flaps

64 and 65 are then folded to overlie the package contents, these flaps being flexed out of a common plane due to the angular inclination of the fold lines 69 and 70 at one end of the package and the

fold line extensions

71 and 72 at the opposite end thereof. The closing flaps 53 and 54 are then folded to overlie the first folded flaps. Any convenient means is provided for sealing the flaps in closed position, Figure 7 illustrating a pair of short lengths of pressure sensitive tape 80 for this purpose. These short lengths of tape overlie the junctures between certain of the flaps and seal the package in closed position.

It will be seen that the package C when folded as indicated in Figures 6 and 7 of the drawings, has an end to that shown in Figure 3 of the drawings. When the folded package is viewed in plan as in Figure 7 of the drawings, they will be seen that the central portions of the end walls which are defined by the parallel fold lines are somewhat closer together than the ends of the end walls, the end walls flexing outwardly so that the longitudinal edges of the package are longer than the center portion thereof. The package thus formed is accordingly distinctive in appearance as it is of unusual shape. At the same time, however, the top and bottom surfaces of the package are parallel so that the packages will stack readily and will rest flat one upon the other when placed in a shipping container or placed on display.

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