4 Claims.

This invention relates to packaging, and more. particularly to a multiple package .structure adapted to be. formed from a unitary cutout or blank to thus provide in effect a multiple section package which may be sold or dispensed in that form with its appropriate contents and later separated or pulled in twain by the purchaser to thereupon produce two or more separated packages; each of which is.v provided throughout with fully sealed edges.

In summary, the invention involves the provision of a cardboard cutout or blank of such configuration that it may be suitably folded to provide two or more box-like containers or packages joined together in such fashion by inter-leafed webbing, the adjacent surfaces of which, are suitably bonded upon themselves, as by the conventional gluing, to provide a rigidified structural entity comprising a plurality of open ended containers, the inner ends of which are demarcated by the said inter-leafed webbing, which containers may then .be. appropriately filledv and sealed to provide a multiple packagewhich may be efficiently utilized in dispensing or selling packaged food to purchasers. The multiple package may then be severed at the time for use by the purchaser to resolve the container into. its component parts and thus provide separated and completely sealed packages which may then be individually opened for use.

These and other objects of the invention will be apparent from the following description taken in conjunction with the drawings forming part of this specification, and in which:

Figure 1 is a planview-of. a blank embodying the invention forming the subject matter hereof;

Figure 2 is a partial view in side elevation of the structure of the invention, showing the same as it appears in an early stage of folding;

Figure 3 is a view of the nature of that of Figure showing a later stage of folding;

Figure 4 is a partial view in perspective of the semi-folded blank;

Figure 5 is a view in perspective showing the container structure in fully folded, or assembled, condition;

Figure 6 is a wewin section taken along lines E5 of Figure 5; and

, Figure 7 is a perspective-of the container structure showing the sections thereof in semi-separated condit" on.

Referring to the drawings for more specific details of the invention, and to Figure 1 in particular, and using the abbreviated vertcal edges til, shown insolid. outline, .as reference, lines in ,2 describing. the structure of: the multiple container blank and the .way it is. folded. to form theresultant *multiplepackage, it will be seen that the configuration of theiblank, as it appears to the right of the righthand edge of the two edges iii is precisely similar totheconfiguration of that portion of the blank .locatedto the left of: the lefthand edge of the two edges; Hi. Usingrsimilar reference numbers for :bothz. of these'outer and major blank portions, itxtwill 'be seen: thatdeach portion comprises equi-sized panels l2 and'l4 joined together by a smallerpanel ldwhich latter panel equal in area ton-apanelxlt located, in Figure l beneath :panel'. Iii. A smaller panel .20 is carried above. each of the-panels i2. The panels 42-- i are demarcated by; score. lines designated from top to bottomas: 22..to .23,:r.espectively. The larger panels i2. and 1410f the. two. symmetriealhalfzportions of the blank are provided with laterally extendingxflaps 33:.and 32, while-the, smallerlpanels: I 5; and o 18; are provided, respectively,with'fiaps 34, and 35. The flaps 3@J36 are demarcated with respect to their adjacent panels by. score :line. 38. Additionally, the panels i Za re joined tog ther, by fiapsililwhichareintegral,

being characterized by-a, central. score line d2. Theflaps iii areprovided withlarcuatezedges it for a purpose hereinafter disclosed. Panels is are provided with flaps 46 having integral therewith isosceles triangular-.membersvs having :a base equal to the-combined length of the flaps ie-and demarcated by score linewfiil. The. flaps 46 are separated across theirmainreetaheular body portion-by slot .52. The triangular tabs 48 are 5 provided with main score linestii and each of the triangular tabs is further provided with a pair of auxiliary score lines '55.

In describing the folding operation whereby the multiple section container is formed, the description will be initially directed, for purposes of clarity, to a description of the folding of the major portions of the blank, that is, the, portions to the right and left, respectively, of the righthandand lefthand edges i ii. It-.-wi1l be clear. that when these. portionsare folded uponscore lines 22- 28, :a pair of semi-boxes will be formedin which thejpanels l2. and Mare the larger sidewalls, the panels I6 and 18 the smaller and oppositely disposed sidewalls, and that the small flap tdmaybe glued to-panel 8 after the manner of the conventional, glue flap arrangement. After this operation has been completed, it will be clear that the flaps 4:) are oppositely d sposed with respect to. their counterpart portions of flapsdfi, and that-the: flapsdamay' be considered as ,re-

siding within the plane of the panels l2, with the flaps 46 and triangular tabs 48 being considered as residing within the plane of the panels l4.

As the semi-boxes are then moved angularly toward each other about the axis in which the score lines 42 and slot 52 reside, the flaps 40 will become doubled upon themselves to form a knife edge, so to speak, constituted by the score line 42, which knife edge may be inserted through the slot 52 for interlocking engagement, as shown in Figure 2, until the score line bases of the flaps 40 reach the actual slot edges of the slot 52. Then, by grasping the doubled flaps 40 and pivoting the semi-boxes toward their original relation of alignment, as shown in Figure 3, it will be clear that, when the upper surfaces of flaps 40 are provided with glue, and when the under sides of flaps 45, as viewed in Figure 1, are likewise provided with glue, that these surfaces, when finally juxtaposed, may be pressed together to constitute a four thickness wall serving as the wall dividing the previously communicable spaces of the two semi-boxes into what actually consists of a double ended container, or, rather, a multiple container joined together as an integral whole.

In this process of forming the common wall for the two portions of the container the triangular tabs will be so collapsed and bent upon each other with respect to their portions as defined by the respective score lines thereof 54 and 56, as by collapsing the sub-triangles of each half of the triangular tabs G8 upon each other, as to form lateral reinforcing wings of the configuration shown in Figures 4 and 5 which are glued to the panels l8 and extend across the junction zone of r the juxtaposed walls of the boxes. The triangular tabs, when in their final, or glued, position of Figure 5, serve as truss members to secure the two sections of the package together and maintain them in alignment as a single unit.

When it is desired to separate one of the sections from the multiple section container, the container is subjected to a joint-breaking action along the transverse plane of least resistance constituted by the score lines 132 and 54, as illustrated in Figure '7. The respective sections then constitute separate and complete packages or containers.

The physical effort required in the joint-breaking action, which may be done by hand or with the aid of a knife, or the like, is minimized by the fact that score line 42 is of relatively short length due to the provision of the arcuate edges 44 for the flaps 48. The arcuate edges 44 also make it easier to insert the flaps through the slot 52, as will be readily understood. While it is preferred that the flaps 49 be interconnected in order that the flaps may be manipulated as a unit and that the fiaps ill be provided with the arcuate edges 44, it will be appreciated that the flaps in may be rectangular, as are flaps 46, and that they may be unconnected, without at all departing from the spirit of the invention.

When the multi-section package has been divided into two sections, each of which is then a complete box or package, all four edges of each package at the previous plane of joinder of the sections are fully sealed, with the result that the separated packages are each as airtight as they previously were when they were joined together. The upper edge of the joinder end of each package is constituted by the line of connection between panel M and flap 46, reference being had to the package orientation of Figure 6, and this line of connection is not disturbed by the jointbreaking operation. The lower edge of the joinder end of each package is constituted by the line of connection between panel 12 and flap 40, and this line of connection is not disturbed by the joint-breaking operation. The interfaces of flaps 10 and 16 are secured together, as by glue. This leaves the side edges of the joinder end of the package to be considered. Prior to joint-breaking, both side edges were constituted by the lines of connection 50 between the triangular tabs 48 and the flap 46 (see Figure 1) and half of each tab was folded and wrapped around edge ID of panel 18, or the corresponding edge of panel [6, and secured, as by gluing, to panel H3 or panel 16. These lines of connection and the wrap-around edge seal provided by the half portions of triangular tabs 43 are not disturbed by the jointbreaking operation.

The invention claimed is:

l. A blank of cardboard or the like for the formation of multiple package containers, comprising a single sheet of material cut out to form identical, late-rally disposed, parallel oblong sections, each section being similarly scored on spaced transverse fold lines defining a plurality of pairs of oppositely disposed panels, the adjacently disposed ends of one of the pairs of panels being provided with foldable flap-like extensions connected together to constitute a web foldable medially along a line disposed in parallel relation to said adjacently disposed ends of said pair of panels, said flap-like extensions being symmetrically tapered inwardly to make their line of jcinder of shorter length than the length of said adjacentiy disposed ends of said pair of panels, the adjacently disposed ends of a second pair of panels alternately arranged with respect to first-mentioned pair of panels being provided with inter-connected foldable flap-like extensions, said latter flap-like extensions being provided along their line of joinder with a slot disposed in parallel and in alignment with the line of joinder between said first-mentioned flap-like extensions, with said slot being of greater length than said first-mentioned flap-like extensions.

2.
