12 Claims. (Cl. 99`-174) This invention relates to packaging and is more par'- ticularly concernedtwith improvements in a package of sliced bacon or similar merchandise.

It is a general object of the invention to provide a consumer package of a predetermined quantity of a product,.such as sliced bacon, or the like, enclosed in an outer container orl wrapper of a character which adequately protects the product while permitting' portions thereof to be viewed through a transparent portion thereof and which permits the package to be readily handled without disturbing the arrangement of the product in the wrapper or affecting the appearance of the same, thereby facilitating thehandling and transporting of the package and the display thereof in the retail store.

It is a more specific object of the invention to provide a neatand attractive package of a predetermined quantity of bacon, or a like product, in sliced slab arrangement, with the slices extending in'face engaging relation lengthwise of the slab and in a tilted position relative tothe bottom face of the slab so that a narrow upper edge portion of each slice is visible when viewed'from the front and top of the slab, the sliced slab being enclosedin a wrapper or carton having a body portion comprising bot-v tom, front and rear side walls and connecting end'walls, and a hingedcover portion, with the front and rear side walls arranged so that the package has a cross section in the direction transverse of theslab which is in theform of a parallelogram.

It is another object of the invention to providea package of a product of the character described wherein a predetermined mass of the product is enclosedl in a collapsible preformed container of paperboard or' similar material, the container being generally rectangular in longitudinal cross section and forming a parallelogram in transverse cross section.

It is a further object of the invention to provide a package which is characterized by a predetermined mass of a product, such as sliced bacon, and a protective wrapper which encloses the same, wherein a plurality of relatively thin slices of the product are arranged in face engaging edge supported and` tilted relation, with the slices tilted at an angle suicient to expose a relatively small marginal portion of the face ofy each slice at the top surface of the package and to form a generally rectangular mass or unit having substantial depth, and a transverse cross section in the form of a parallelogram, and wherein the protective wrapper comprisesV a sheet of paperboard or'similar material which is cut 4and folded to provide a bottom forming member upon the upper face of which the mass of the product is supported, upwardly and rearwardly vinclined bottom, front and rear side walls, upstanding bottom end walls connecting the ends of the bottom side walls, a hinged cover member connected along one edge thereof'to the top edge of one of the side walls, a depending side Wall member extending along the opposite edgeof the cover member, and end wall members depending from the ends of the iceV window in at least a portion of the cover member through which exposed portions of the sliced product may be viewed.

It is another object ofthe invention to provide a package of a product of the character described wherein the product isr enclosed in a paperboard wrapper which is cutandcreased to provide .a plurality of connected panels which are adapted to be erected into container wall forming relation with a body or bottom forming section and a hingedly. related cover forming section and with the container in erected and closed condition having im transverse section theform of a parallelogram whereby' sliced slabs ofbacon or similar products ofthe same weight or mass but varying in depth or thickness may be enclosedin a wrapper of uniform dismensions without varying-.the .size or shape of the package.

It is stillanother object of the invention to. provide a. blankfor. forming a collapsible container or wrapper which comprises a sheet of paperboard, or similar material, cutand creased to divide the same into hingedly connected .panels which, when erected into container Wall forming relation provide a body forming section and a hingedly connected cover forming section,r the. body and cover forming sections of the blank beingk divided by transversely and longitudinally extending crease lines into bottom, top, side and end Wall forming panels, with the respective. end wall forming panels extending along the: opposite side edges of the: blank and being further divided bydiagonal crease lines into wall forming sections of: rhomboidA shape and end connecting sections of triangular shape.

Fig. 16 is a plan View, on a reduced scale, of the cut and scored blank which forms the wrapper for the package of Fig. 13.

Referring irst to Figs. 1 to 8 there is illustrated a form of the package which is characterized by an outer wrapper, or container 10, of predetermined size and shape, and a predetermined quantity of a product,.such as, a two pound mass or unit ofsliced bacon 11 in which the slices have been allowed to remain in their original position in the slab. The bacon slices 11 are arranged in face to face, edge supported, and tilted relation, so that a predetermined quantity or weight thereof may be positioned in the container, the slices being tilted more or less as required by their depth which will Vary according to the thickness of the bacon slab.

The outer wrapper or container for the package is f formed from a generally rectangular blank or sheet 12 of paperboard, which is relatively liexible and which is adapted to be cut and scored or creased, as shown in Figs. 5 to 8, so that it may be folded to provide a container of predetermined size and shape. The exact sheet material used for the blank 12 may be varied. Any sheet material which may be cut and scored as illustrated can be employed in the manufacture of the wrapper, the choice of the material being dictated by the nature of the specific product with which the wrapper is used.

The rectangular blank 12 is divided into container bottom and top or cover forming sections 13 and 14 by a transverse score line 15 which constitutes the hinge line connecting the two container forming sections. The bottom forming section 13 is provided with transversely ex tending score lines 16 and 17 which are parallel with and longitudinally spaced from the transverse score line 15` and which are adapted to form the bottom, front and back corner edges of the container. The transverse score lines' 16 and 17 extend 'between transversely spaced longitudinally extending score lines 18, v19 and 20, 21, which are spaced inwardly of the opposite side edges of the blank 12. The score lines 16, 17, 18 and 20 define the panel 22 which constitutes the bottom wall of the bottom or body section of the container. The score lines 17, 19, 21 and the end edge 23 of the blank define the panel 24 which constitutes the front wall of the bottom section of the container. The blank material is cut along the longitudinal lines 25 and 26 which are in alignment with the scoreI lines 18, l19 and 2t), 21, respectively. The cutting lines 25 and 26 extend between the ends of the transversescore lines 15 and 16 and define therewith the panel 27 which constitutes the back wall of the bottom section of the container.

The marginal portions of the blank which extend along opposite side edges thereof and outwardly of the longitudinal lines 25, 18, 19 and 26, 2t), 21, respectively, are cut and scored to divide these portions into container end wall and corner connecting panels. Since these blank portions are cut and scored in an identical manner, only the marginal portion at one side will be described in detail, corresponding lines and areas on the marginal portion at the other side being indicated by the same numerals primed. The marginal portion at one side is divided longitudinally into panels 2S and 29 by diagonal outwardly diverging cutting lines 30 and 31, which cutting lines 30 and 31 terminate at their inner ends at the intersection of the transverse score line 17 with the longitudinal score lines and 21. The angles formed by the cutting lines 30 and 31 with the longitudinal score lines 20 and 21 are equal and determine the angle of inclination or slant of the front wall panel 24 with respect to the bottom wall panel 22 when the container 10 is in its final form. At its rearward end the panel 28 is scored on the diagonal line 32 which extends outwardly of the intersection of transverse score line 16 with the longitudinal score line 20 and the longitudinal cutting line 26. The score line 32 is parallel with the cutting line 30 which forms the front edge of the panel 28 and these lines together with the longitudinal score line 20 and the free outer side edge 33 of the panel 28 form a parallelogram which determines the cross sectional shape of the final package, the panel area 34 within these lines constituting the bottom end wall of the container. The lblank is cut so that a panel section 35 of generally triangular shape is provided between the score line 32 and the cutting line 26 which forms arear corner connecting tab between the rear end of the end Wall forming panel section 34 and the end of the rear wall forming panel 27. A diagonal score line 36 is provided in the panel 28 within the end wall forming area 34 which extends forwardly and outwardly of the end of the transverse score line 16 and which forms with the diagonal score line 32 and the end portion of the outer edge of the panel a triangular tab section 37 which is adapted to fold about the score lines 32 and 36 when the corner connecting tab section 3S has its outer face secured to the inner face of the rear side wall forming panel 27 and the end wall 34 is moved from a collapsed position to an upright or set-up position. A further diagonal score line 38 is provided within the end wall forming panel section 34 which extends rearwardly and outwardly from the end of the transverse score line 17 and which bisects the angle between the longitudinal score line 20 and the forward end edge 30 of the panel, to permit the forward portion of the panel to fold upon itself when the front corner connecting panel or tab 29 is secured to the inner face thereof in the area between the score line 38 and the end edge 30.

The front corner connecting tab or panel 29 extends outwardly of the longitudinal score line 21 and is adapted to hinge about the latter when it is connected to the end of the panel 34 and the latter is moved from a collapsed to an upright or erected position in setting up the container. The panel 29 may be reduced in depth somewhat by cutting away the forward end edge of the blank at 39.

The top or cover forming section 14 of the blank 12 is provided with a transverse score line 40, which is longitudinally spaced from the transverse score line 15, and transversely spaced longitudinally extending score lines 41 and 42, the latter extending in alignment with the longitudinal score lines 18 and 20, respectively, of the bottom forming section 13 of the blank. The score lines 40, 15, 41, and 42 define a top forming panel 43. The 'blank is cut on the lines 44 and 45 which are in longitudinal alignment with the score lines 41 and 42, respectively, andwhich extend to the end edge 46 of the blank. The score line 40 and the cutting lines 44 and 45 together with the end edge 46 dene a top front wall forming panel 47 of approximately the same size as the bottom front wall forming panel 24.

The opposite `side marginal portions of the cover forming section 14 of the blank 12 which extend outwardly of the scoring and cutting lines 41, 44 and 42, 45, respectively, are 4cut and scored to provide identical end wall forming and front corner connecting panels. Only one of these marginal portions will be described in detail, the corresponding lines and areas on the other being indicated by the same numerals primed. The marginal portion of the blank which extends outwardly of the longitudinal score line 42l and cutting line 45 forms a panel 48,

which is cut at its inner end on a diagonal line 49l extending rearwardly and outwardly of the end of transverse score line 15 and generally parallel with the score line 32 and the cutting line 30 of the bottom end wall forming panel 34. At its other end the panel 48 is scored on the diagonal line 50 which extends outwardly and rearwardly of the end of the transverse score line 40 and which is parallel with the ycutting line 49. The score lines 42, 50, and the cutting line 49 together with the outer edge 51 of the panel 48 form a parallelogram and define a panel area 52 which constitutes the top end or tab sections` 35, 35'.

wall 'of the container. The end of the panel 48 is cut to provide a generally triangular end connecting tab portion or panel section 53 which is freed from the end of the front end forming panel 47 along the `cutting line 45 and is 'adapted to be secured to the inner face of the panel 47. A diagonal score line. 54 is provided in the panel 47 within the end wall forming area 52 which extends forwardly andv outwardly of the end of the transverse score line 40 and which is parallel with the score line 36 in the bottom end wall forming panel 34. The score line 54 defines with the diagonal score line 50 a triangular tab section 55 which is adapted to fold about the score lines 50 and 54 when the corner connecting tab section 53 has its outer face secured to the inner face of the front wall forming panel 47 and the end wall 52 is moved from collapsed to upright position.

The top cover forming section 14 ofthe blank 12 is provided with a generally rectangular aperture 56 which extends from the top wall forming panel' 43 across the score line 40 into the front wall forming panel 47 and which is provided with a transparent covering sheet 57 to permit the contentsof the finished package to be observed. A tab formation 58 may be' provided which projects into the aperture 56 for labeling or. advertising purposes. The front wall panel 24 of the bottom section 13 of the blank is cut away at 59 to correspond with the aperture in the front wall panel 47 of the cover section 14 when these panels are superimposed in the completed package.

In setting up the blank 12, -or'folding the panels of the same, to form the collapsed container which is supplied in collapsed condition to the user, the end wall forming and corner connecting panels 28, 28', 29, 29' and 48, 48' are rst folded to the positions shown in Fig. 6. The front corner connecting panels 29 'and 29 are folded inwardly about the score lines 21 and 19, respectively. The bottom and top end Wallvforming panels 28, 28 and 48, 48 are folded inwardly about the score lines 20, 18 and 42, 41, respectively. The triangular portions of the bottom end wall forming panels between the score lines 38, 38 and the forward ends 30, 30 of these panels are folded outwardly about the score lines 38 and 38 and an adhesive is applied in the stippled areas indicated at 60, 60 (Fig 6). The triangular sections 35, 35 and 37, 37' at the other ends of the end wall forming panels 28, 28 are folded outwardly about the `score lines 36 ,36' and then inwardly upon themselves about the score lines 32, 32' and an adhesive is applied on the uppermost or exposed face of the triangular sections 35, 35 as indicated by stippling in Fig. 6. The top end wall forming panels 48, 48 are first folded inwardly about the longitudinal score lines 42 and 41, respectively, and thereafter the triangular panel sections 53, 55 and 53', 55' at the ends thereof are folded first outwardly about the score lines 54, 54 and then inwardly upon themselves about the score lines 50, 50 and an adhesive is applied to the exposed uppermost face of the end corner connecting sections 53, 53k as indicated by stippling in Fig. 6. The front end wall formin`g'panels24 and 47- of the bottom and cover sections, respectively, of the blank are then folded inwardly about the transverse score lines 17 and 40, respectively, tofbring their end portions into overlapping relation with the adhesive coated areas on the end portions of the folded end wall panels. The blank is then in the partially folded condition shown in Fig. 7. Finally, the top wall forming' panel 43iand the rear wall forming panel -27 are folded about the transverse score line 16 which brings the ends of the inner face of the rear wall forming panel 27 into engagement with the adhesive coated areas of the corner lconnecting panel The folding operations are then complete and the' container 10"is in collapsed condition asshownin Fig; 8V in which' it`is supplied to the user.

In order to set up theY container 10 for receiving the .sliced baconv 11, Orother'm'erchandis'e, the entire cover section 14 and the rear Wall`forming panel 27 of the bottom forming section 13 are hinged about the bottom rear corner forming score line 16 to bring the rear Wall 27 into upwardly and rearwardly inclined relation relative to the bottom wall 22 of the bottom forming section. This movement causes the end wall forming panels 34, 34' to` open outwardly about the bottom end corner forming hinge lines 18 and 20 into upright position carrying with them the bottom front wall 24 and bringing the latter into upright rearwardly inclined position as shown in Fig. 4. The front ywall forming panel 47 of the cover may then be hinged about the scoreline 40 to open up the cover and to cause the end walls 52, 52 to unfold or swing outwardly about the score lines 42, 41 into depending relation from the ends of the 'top wall 43. The sliced slab of bacon may then be inserted in the bottom forniing portion of the container and the slicesv tilted the required amount to `cause the mass of bacon to conform to the depth and parallelogram shape of the container. One or more strips of transparent tape or any other suitable fastening means may be employed to secure the top and bottom portions of they container in closed condition. The container is adapted to receive the same quantity, by weight, of bacon slices, regardless of the variations in depth or thickness which are encountered in this particular product. yWnen the depth or thickness of the slab is above or below the average depth or thickness of this type product, the slices are merely tilted a greater or lesser amount which varies the shape of the cross section of the mass formed by the strips but does not materially change the total area so that there may be considerable variation in the depth of the slab andthe packages will be uniform in size, shape and appearance.

The package may be formed as illustrated in Figs; 9 to l2, with a simplified form of blank which is cut and creased or scored as shown particularly in Fig. 12. The blank 100 is generally rectangular in shape and is divided into body and cover forming sections101 and 102 by a transversely extending score line 103 intermediate the end edges of the blank. v

The body or botto-m forming section 101 is divided by the transversely extending score line 104, which is parallel to and longitudinally spaced from the score line 103 and the longitudinally extending transversely spaced score lines 105, 106 and 107, 108 into bottom forming and rear side wall forming panels 109 and 110, the score lines 103,. 104, and 107 dening the bottom wall forming panel 109 and the score lines 104, 106 and 108 together with the end edge 111 of the blank defining the rear side wall forming panel 110.

The lbottom forming section 101 of the blank 100 is provided along its opposite side margins with panellforming portions or extensions which are cut and scored in an identical manner. Only one of these'side marginal portions will be described in detail, corresponding lines and areas on the other one being indicated by the same numerals primed. The marginal portion 112 which extends outwardly along the longitudinal score line 105, 106 is divided into inner and outer panel portions 113 and 114- by longitudinally extending score line 115 and cutting line 116, the latter extending inwardly from the marginal edge of the portion 112 whichis in transverse alignment with the score line 103. The cutting line 116 extends between a triangular tab portion 117 and a rectangular flap portion 118, which are divided off from the panels 113 and 114 by diagonal and transverse score lines 119 and 120 on the respective panels, the score line 119 ex-v tending outwardly of the end of the transverse score line 103 and the score line 120 extending from the point of intersection of the score line 119 with the longitudinalk score line 115, which is also the end of the cutting line 116. The panels 113 and 114 terminate at the other end on the cutting lines 121 and 122, which are parallel with the score lines 119 and 120, respectively, the diagonal cutting line 121 extending outwardly of the end of the transverse score line 104 where it intersects the longitudinal score lines 105 and 106. The end marginal portion of the blank is also cut on the oppositely directed diag onal line 123 to define with the diagonal cutting line 121 and the longitudinal score line 106 a triangular end tab 124 on the side wall forming panel 110 which is adapted to ybe folded about the score line 106. The score lines 105, 115, 119 and the cutting line 121 form a parallelogram which determines the cross sectional shape of the package, the area 125 enclosed within these lines constituting the end wall of the bottom forming portion of the wrapper or container in the completed package.

The cover forming section 102 of the blank 100 is divided by longitudinally spaced transverse score lines 126 and 127 into a rectangular top forming panel 128 and adjoining rectangular front and rear wall forming panels 129 and 130. The top wall forming panel and the front wall forming panels 128 and 129 are substantially the same size as the bottom wall forming panel 109 and the rear wall forming panel 110 while the rear wall forming panel or flap 130 is somewhat narrower than the rear wall forming panel 110. The flap 130 is provided with a T-shaped locking projection 131 integral therewith and extending from the end margin or edge 132 of the blank which is adapted to be received in a locking slit 133 provided in the rear wall forming panel 110. The top panel 128 and a portion ofthe rear side wall panel 129 are provided with an aperture 134 which is covered with a suitable transparent film 135 to permit the contents of the package to be observed.

ln forming the package with the blank 100, the unit or mass of sliced bacon, or other product 136, is positioned with the bottom edge or face in engagement with the inner face of the bottom wall forming panel 109 of the blank and the bottom slices are tilted towards the score line 104 while the rear wall forming panel 110 is folded upwardly about the score line 104 to its inclined position, the end corner tabs, 124, 124 lbeing folded inwardly about the score lines 106 and 108, against the ends of the bacon mass. Thereafter the end wall panels 113, 113 are folded into upright position about the score lines 105 and 107, and the triangular end tabs 117, 117 are folded inwardly about the score lines 119, 119' into engagement with the forward face of the rearwardly tilted bacon mass. Thereafter the rectangular panels 114, 114' are folded inwardly about the score lines 115, 115 into engagement with the end margins of the top surface of the bacon mass and the end flaps 118, 118 are folded down into engagement with the exposed -faces ofthe triangular tabs 117, 117. Thereafter the fro-nt wall forming panel 129 is folded about the score line 103 upwardly and rearwardly over the face of the foremost strip of bacon and the top cover panel 128 is folded about the score line 126 down into engagement with the top surface of the `bacon mass. The rear side iiap 130 is then folded about the score line 127 over the edge 111 of the rear wall panel 110 and the locking tab 131 is engaged in the slit 133 in the former. The end wall members 113, 113 may be held in upright or assembled position with the contents of the package by the use of transparent tape or other suitable yfastening means, or overlapping portions of the end and/or cover walls may be provided with a pressure sensitive adhesive or the like which will hold them in positionv as the wrapper is assembled with the merchandise so that the package will retain its shape.

Another form of the package is illustrated in Figs. 13 to 16 in which the blank 200 is cut and scored as shown particularly in Fig. 16. The blank 200 is generally rectangular in shape and is divided into 'body and cover forming sections 201 and 202 by a transversely extending score line 203.

The body or bottom forming section 201 is divided by the longitudinally spaced transversely extending score lines 204, 205 and the transversely spaced, longitudinally extending score lines,206, 207 into bottom forming panel 208, rear side wall forming panel 209 and front side wall forming panel 210.

The bottom forming section 201 of the blank 200 is provided along its opposite side margins with panel forming portions or extensions which are cut and scored in an identical manner. Only one of these side marginal portions will be described in detail, corresponding lines and areasv on the other being indicated `by the same numerals primed. The marginal portion 211 which extends outwardly along the longitudinal score line 206 is divided into inner and outer panel portions 212 and 213 by a longitudinal extending score line 214. The panel portion 212 is scored on parallel diagonal lines 215 and 216 which extend outwardly of the ends of the transverse score lines 204 and 205, respectively, to the ends of the longitudinal score line 214. The diagonal score lines 215, 216 and the longitudinal score lines 206, 214 form a parallelo gram which determines the cross sectional shape of the package, the area enclosed within these lines constituting the end wall of the bottom forming section of the wrapper or container in the completed package. The panel 213 which extends outwardly of the longitudinal score line 214 is rectangular in shape and its length corresponds to the dimension of the bottom forming panel 208 in the lengthwise direction of the blank. The blank is cut at one end of panel 212 to provide between the diagonal score line 215 and the cutting line 217 which defines the side or end edge of the back wall forming panel 209 a generally triangular corner panel or tab portion 218 which is foldable about the diagonal score line 215 and at the other end of panel 212 a generally triangular corner panel or tab portion 219 which is foldable about the diagonal score line 216.

The top or cover forming section 202 of the blank 200 is divided by longitudinally spaced transverse score lines 220 and 221 into a rectangular top wall forming panel 222 of substantially the same size as the bottom wall forming panel 208, a rectangular front wall forming panel 223 of substantially the same size as front wall forming panel 210 and a locking panel or ap 224. The iocking panel or flap 224 is provided with an integral fastening means along the free end edge 225 of the blank which consists of two transversely spaced oppositely directed hook formations 226 which hook formations are adapted to be engaged in locking relation in cooperating slit formations 227 in the bottom wall forming panel 208 when the package is completely closed. A

The top wall forming panel 222 and the front wall forming panel 223 are provided with an aperture 228 which is covered by a sheet of suitable transparent lm material 229 while the front wall forming panel 210 is Vrecessed or cut away along the free end edge at 230 to permit a substantial portion of the top and front surfaces of the contents 231 of the package to be observed when it is enclosed in the wrapper.

In forming the package with the blank 200, the unit or mass of sliced bacon, or other product, 231 (Fig. 14) is positioned on the bottom wall forming panel 208 and the bacon slices are tilted in the direction of the rear side wall panel 209. The end wall panels 212, 212' are folded inwardly about score lines 206 and 207 to upstanding position.
