Abstract

This disclosure relates to a partition formed from ''''twosided'''' paperstock material wherein a blank of two-sided material is folded to form a longitudinal partition panel and at least a single transverse partition panel at each side of the longitudinal partition panel. A portion of the blank at each side of the longitudinal partition panel is struck to form a shockabsorbing flap, and each flap is folded upon its adjacent transverse partition panel with the same side of the two-sided material in face-to-face bonded relationship whereby the bond strength is thereby materially increased as opposed to the bond strength which would exist if opposite sides of the shockabsorbing flap and the transverse partition panel were bonded together.

TWO-SIDED BOTTLE CARRIER PARTITION Paperstock material never has identical appearance and surface characteristics on both sides of the sheet, and this difference in appearance of the two sides of paper is referred to as two sidedness. All paperstock materials have a certain amount of two sidedness and in general the top side of the paper is smoother and has a closer formation than the wire side, but not always.

Two sidedness may be an actual structural two sidedness due to greaterconcentration of size, pigment or fines on one side of the sheet, or it may be an optical two sidedness caused by a difference in the finish or reflection on the two sides of the sheet. Most paperstock material, and particularly thicker paperstock material of the type used to form bottle or can carriers, cartons, wraparound carriers or the like, show definite two sidedness in regard to fibrous composition. This is usually manifested in a preponderance of larger fibers on the wire side and a preponderance of finer, smaller fibers on the felt side.

Two sidedness may be caused by one or more of the following factors:

1. loss of fine fibers through the wire before a mat of th larger fibers is laid down;

2.'slower settling of the fine fibers, due to their reduced specific gravity and hydrodynamic resistance, with the result that a higher percentage of fines are deposited on the top side of the sheet;

3. removal of the finer fibers from the underside of the wet sheet after formation due to the action of the table rolls and the suction boxes.

Increased machine speeds have over the years also added to an increased amount of two sidedness.

It is known that the effect of greater concentration of fine material on the felt side results in an increase in the strength of the paperstock, an increase in smoothness, and the improved printing qualities on this side of the paper. This is obviously the desirable side upon which to print such things as the identification of the manufacturer or producer of the product,

as is typical of wraparound-type carriers, but it is also the least 4 desirable side to apply adhesive since the bond strength is' reduced due to the relatively nonporous nature because of the concentration of fine material on the felt side, as opposed to the wire side which has a greater bond strength because of the lesser amount of fine material.

Though twosidedness is ordinarily undesirable in writing paper, it is intentionally sought after in the carton and carrier manufacturing industry for reasons of economy and improved products. For example, paperboard made on a cylinder machine is often made intentionally two sided by using different grades of stock in the liner and filler plies. In this way, cheaper stock can be used in the filler and more expensive stock used in the outside plies, with the latter again being more desirable for printing purposes and the former for adhesive purposes.

Recognizing the desirability of using such two-sided paperstock for carriers, cartons and partitions thereof, and also recognizing the desirability of using one side of the paperstock material for one particular purpose and an opposite side thereof for another, it is a primary object of this invention to provide a novel partition constructed from a blank of two-sided material folded to form a longitudinal partition panel, a plurality of transverse partition panels at each side of the longitudinal partition panel, and a plurality of shock-absorbing panels struck from the material of the blank to provide multiply thicknesses to prevent article damage between adjacent compartments with the shock-absorbing flaps being adhesively bonded upon adjacent portions of the blank with one and the same side of the material in face-to-face bonded relationship.

It is a further object of this invention to provide a novel partition of the type described wherein the bonds are formed across the more porous side of the two-sided blank.

A further object of this invention is to provide a novel partition of the type heretofore described wherein a pair of transverse partition panels at each side of the longitudinal partition panel are joined to each other by a connecting panel, and each connecting panel has struck therefrom a shock-absorbing flap which is likewise folded upon one of the transverse panels and is bonded thereto between the more porous side of the blank.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claimed subject matter, and the several views illustrated in the'accot'npanying drawings.

In the Drawings:

FIG. 1 is a top plan view of a two-sided blank for forming a partition in accordance with this invention, and illustrates the blank with its smoother, least porous and least bondable side uppermost.

FIG. 2 is a top plan view of the blank of FIG. I, and illustrates the blank after being partially folded.

FIG. 3 is an edge view of the blank of FIG. 2 looking from bottom to top, and more clearly illustrates the manner in which the blank is folded.

FIG. 4 is a fragmentary top perspective view of the partition blank after having been completed and inserted within a carton or carrier.

FIG. 5 is a fragmentary perspective top view similar to FIG 4, and illustrates the opposite side of the partition and carton.

FIG. 6 is a sectional view taken generally along line 6-6 of FIG. 4, and illustrates the manner in which shock-absorbing flaps are folded out of the planes of longitudinal panels and connecting panels to form multiply transverse dividers between centermost and endmost compartments on each side of the longitudinal partition.

FIG. 7 is a sectional view taken generally along line 77 of FIG. 6, and more clearly illustrates details of the partition and particularly the two-ply construction of the leftmost transverse divider.

FIG. 8 is a sectional view taken generally along line 8-8 of FIG. 7, and illustrates the manner in which one of the shockabsorbing panels has been pivoted out of the plane of its associated connecting panel.

Reference is first made to FIG. 1 of the drawings which illustrates a blank 10 of two-sided" paperstock material of the type heretofore described. In view of the two-sided" nature of the blank 10 and for the purposes of describing the relationship thereof to the formation of a carton or carrier 15, the blank 10 of FIG. 1 has applied to the visible side thereof a plurality of reference characters S1 which represent the smoother side of the blank 10 while the opposite side of coarser more porous material is designated by the reference numeral S2. FIG. 1 illustrates the blank 10 prior to being folded in any manner, and therefore only side S1 is visible.

The blank I0 is provided with three longitudinal partitionforming panels ll, 12 and 13 with the panel 11 being connected to the panels l2, 13 along respective fold lines l6, 17. The panels ll, 12 and 13 include respective carrying-

handle portions

18, 20 and 21. The handle-carrying portion 18 includes a pair of rectangular openings 22 while the

handle portions

20, 21 each include a pair of openings 23 and a flap 24 joined to the carrying-handle portion by a fold line 25. The flaps 24 are folded in a known manner to overlie the uppermost edges of the openings 22 to permit the carrier 15 to be easily carried.

The blank 10 further includes a pair of transverse compart' ment-forming

panels

26 and 27. The transverse compartmentforming panel 26 is partially formed from the material of the longitudinal panel 12 and includes a first transverse panel 28 joined to the longitudinal panel 12 along a fold line 30, a connecting panel 31 joined to the first transverse panel along a fold line 32 and a second transverse panel 33 joined to the connecting panel 31 along a fold line 34. A terminal panel 35 is joined to the second transverse panel 33 along a fold line 36. A cut line 37 separates the panels 28, 3] from the longitudinal partition panel 12.

A shock-absorbing flap or panel 38 is struck from the material of the connecting panel 31 along a pair of generally

parallel cut lines

40, 41 and a sinusoidal cut line 42 therebetween. The shock-absorbing panel 38 is joined to the panel 33 along the fold line 34, and as viewed in FIG. 1 the shock-absorbing panel 38 projects from left to right away from the fold line 34.

Another shock-absorbing panel 43 is struck from the material of the longitudinal partition panel 12 along a pair of parallel cut lines 44, 45 and a generally sinusoidal out line 46 therebetween. The shock-absorbing panel 43 is likewise joined by the fold line 30 to the first transverse panel 28, and projects away from the panel 28 in a left-to-right direction as viewed in FIG. 1. A connecting panel 47 is also struck from the material of the partition panel 12 along a generally C- shaped cut line 48. The panel 47 is joined to the longitudinal partition panel 11 along the fold line 16 and projects toward the shock-absorbing panel 43 in a right-to-left direction, as viewed in FIG. 1.

The transverse compartment-forming panel 27 is similar in structure to the transverse compartment-forming panel 26 and includes a first transverse panel 50 joined to the longitudinal panel 13 along a fold line 51, a connecting panel 52 joined to the first transverse panel 50 along a fold line 53, and a second transverse panel 54 joined to the connecting panel 52 along a fold line 55. A terminal flap or panel 59 is joined to the second transverse panel 54 along a fold line 56. The

panels

50, 52 are formed from the material of the longitudinal panel 13 and are separated therefrom along an upper edge (unnumbered) by means of a cut line 57.

A shock-absorbing flap or panel 58 is formed from the material of the connecting panel 52 by striking along a pair of

parallel cut lines

60, 61 joined to each other along a sinusoidal out line 62. The shock-absorbing panel 58 is joined to the second transverse panel 54 by the fold line 55 and projects from right-to-left, as viewed inFlG. 1. Another shock-absorbing panel 63 is formed from the material of the partition panel 13 by striking along a pair of generally

parallel cut lines

64, 65 which are connected by a sinusoidal cut line 66. The shockabsorbing panel 63 is joined to the first transverse panel 50 along the fold line 51 and projects from right-to-left.

A connecting panel 67 is also formed from the longitudinal partition panel 13 by means of a generally inverted C-shaped cut line 68, and is joined to the longitudinal partition panel 11 by the fold line 17. The connecting panel 67 projects away from the fold line 17 in a left-to-right direction.

From the foregoing, it will be noted that the blank is identical to the left of the fold line 16 and to the right of the fold line 17 except for the direction of projection of the panels or flaps 38, 43, 47 as compared to the direction of projection of the respective panels or flaps 50, 63 and 67.

The manner in which the blank 10 is folded to form the partition 10 of the carton of FIGS. 4 through 8 will now be described, it being noted that the stipling in FIG. 1 indicates adhesive applied to the surface S1 of the blank 10.

As is best illustrated in FIG. 3, the shock-absorbing panel 58 is folded out of the plane of the connecting panel 52 along the fold line 55 and the side S2 of the panel 58 is brought into adhesive face-to-face contact with the side S2 of the panel 54. The panel 59 is then overfolded to bring its side S2 into overlying though not adhesive engagement with the side S2 of the panel 54. In this position the panel 59 partially overlies portions of the sinusoidal edge 62 of the panel 58. The panel 50 is then folded along the fold line 51 to bring the side S2 of the panel 50 into adhesive face-to-face contact with the side S2 of the shock-absorbing panel 63. In this position the fold lines 17, 53 are in alignment, as is best shown in H6. 3.

Adhesive upon the panel 59 secures the same into face-toface contact with the side S2 of the panel 11.

The shock-absorbing panel 38 is then folded along the fold line 34 and brought into adhesive contact with the side S2 thereof in contact with the side S2 of the panel 33.

The

panels

12, 28 and 31 are then accordion folded along the

respective fold lines

16, 30 and 32 which brings the side S2 of the panel 28 into adhesive face-to-face contact with the side S2 of the shock-absorbing panel 43. This same folding brings the panel 35 with its side S1 in adhesive contact with the side Sl ofthe panel 11.

Thereafter the panel 13 is folded along the fold line 17 in the direction indicated by the unnumbered-headed arrow in FIG. 3 which brings the side S2 of the handle-forming portion 21 into adhesive contact with the side S2 of the handle-forming portion 18. This completes the formation of the blank into the partition 10 which can be opened and inserted into a carton in the manner illustrated in FIGS. 4 through 8, to which attention is now directed to more clearly depict the manner in which the panels are adhesively joined to each other and to the carton.

Referring particularly to FIGS. 4, 5 and 6, the two-sided relationship of the various panels and flaps are more clearly depicted upon the erection of the partition 10 and the formation of the two transverse article-receiving

compartments

26 and 27.

Referring first to the transverse article-receiving compartment 26, the compartment is formed by the two

transverse partition panels

28, 33 and the connecting panel 31. The side S1 of each of the

panels

28, 31 and 33 is inside the compartment 26 while the side S2 of each of the

panels

28, 31 and 33 forms the outside of the compartment 26. Likewise, the side S1 of the longitudinal partition panel 11 forms the fourth wall of the article-receiving compartment 26.

The shock-absorbing panel 43 when folded in the manner heretofore described along the fold line 30 is moved out of the plane of the partition panel 12 with the side S2 of the shockabsorbing panel 43 being brought into engagement and adhesive contact with the same side S2 of the transverse panel 28. The shock-absorbing panel 43 thereby cooperates with a portion of the transverse panel 28 to form a multi-ply, shock-absorbing transverse divider between articles placed in the compartments at either side thereof.

The folding of the shock-absorbing panel 38 in the manner heretofore described, and indicated by the unnumberedheaded arrow associated therewith in FIG. 6,'presents the side S2 of the panel 38 in adhesive contact with the side S2 of the transverse panel 33, likewise again forming a multi-ply, shockabsorbing and reinforcing transverse divider between articles placed in the compartments to either side thereof.

The article-receiving compartment 27 is the reverse of the compartment 26 from the standpoint of the inner and outer sides thereof. That is, the side S2 of the

panels

11, 50, 52 and 54 forms the inside of the compartment 27 while the outside is formed by the side S1. Thus the folding of the shock-absorbing

panels

63, 58 is the reverse of the folding of the

panels

43, 38 in order that the side S2 of the shock-absorbing panel 58 is brought into adhesive contact with the side S2 of the transverse panel 54 and the side S2 of the shock-absorbing panel 63 is brought into adhesive contact with the side S2 of the transverse panel 50, again as best illustrated in FIG. 6.

It will therefore be noted that in both of the article-receiving

compartments

26, 27 the more porous and more readily bendable side S2 of the shock-absorbing

panels

43, 38, 63 and 58 are brought into adhesive contact with the same side S2 of the

respective panels

28, 33, 50 and 54.

Apart from the partition 10, the body of the carton 15 is of a conventional construction, and need not be described in detail except to note that it includes two end panels (unnumbered), two side panels (also unnumbered), and a bottom panel (unnumbered) with the

fiaps

47, 67 being adhesively secured to the end panels, as shown in FIG. 6, and with the connecting

panels

31, 52 being also preferably adhesively connected to the side panels of the carton.

While preferred forms and arrangements of parts have been shown in illustrating the invention, it is to be clearly understood that various changes in details and arrangement of parts may be made without departing from the spirit and scope of this disclosure.
