This invention relates to improvements in the construc-` tion of multicellular foldingA boxes used for the'packaging as a single salesunit of plurality of articles, such as cans, bottles, jars, light bulbs, and the like. j Y y Basically, a multicellularfolding box comprisesa botf tom, upright sidewalls anda top orcell panel inwhich a plurality of article receiving cells are formed. The lindividual cells are separated lfrom one another by transv verse web structures, and the articles of merchandise are seated in the cells in such a wayV thatthe side walls engage the articles at vtwo opposite sides,.whereas the vwebs engage the articles at right angles thereto.

In the simplest form of cell, the square cell, ther are only four points, lines, or areas of contact.

hexagonal, This is accomplished by appropriate [configuration of the web portions of the box blank. yThe web portions of the box are articulated to the side walls and comprise, in most instances, substantially triangular panel portions articulated` to the Side walls along their It has Y been proposed to increase the engagement contacts by making the cells polygonal, for example, by making themv ice j Patented July 12, 1h60 the board. Mechanically it is dicult to flatten out the bottom panel because of the relatively narrow width of thepanelportion between the collapsing crease and the proximate bottom fold line. As Va result, a narrow istrip.' Vofthe bottom panel tends to remain at a slightly/'inclined positionwith respect togthetr'ernainder of the bottom panel, lgiving the box a 'somewhat unsightly appearance when viewed from the fend, infthat onev side wall appears taller than the other.v 1

In :thel' packaging of glass jars and tinv cans it is,im`

v portant 'to hold the receptacles tightly in the cells to i prevent rattling. Aptight t s particularly important in boxes designedtogrip'the chime-end of a can bythe bottom edge of the cell walls, thereby locking the cans Vin the box. It is obvious that' a tight iit is critical in such a box. On the other hand, it is equally plain that in spite rof the tightness of the fit it must be possible to insert thecans without difficulty. Also, the entireY bottom edge ofthe cell walls which engages the canv chimes must be equidistant from the bottomipanel in Orderto provide a fr'eliab'le locking edge.V Prior designs, as far as I am aware, have failed to meet these, requirements.

p The present invention provides an improved construc-v tion of'a multicellular box which may be assembled from'V a at collapsed tubular blank, but requires no special collapsing crease in order to fold it at. The invention provides a cell form which may be a perfect polygon, considering the set up box in plan view. In the cells round articles such as cans and jars. are held snugly and securely because all the sides of the polygonl are equidistant from the central axis of the cell in the set up bases. The cell wall forming portionsof the webs, in"

turn, are articulated to the sides of the triangle.

Webs articulated to the side walls" along triangular .portions possess considerable strength, but present problems which arise from the fact that in the formation of the cells the triangles move from a horizontal to a slanted position, thereby drawing theside walls together and narrowing the width of the cells. The narrowing ofthe cells makes it difficult to insert atfended articles, such as cans or bottles into the box.` In distinction, the distance from web to web does not change during assembly of the box. walls and a loose fit between the webs. This is undesirable, since the individual, articles of merchandise are not securely held, rattle and are free to tilt. y

In order to overcome the narrowing of the cells during assembly of the box, it has been proposedto make the top panel of the box wider than the bottom panel,

in anticipation of the narrowing of the cells during assembly. lThis proposalA however leads to other di-V While the formation of cells of .'.equallongi-g tudinal and lateral dimensions islattained,.the box blank culties.

becomes irregular in that it comprisesa wideftoppanel and a narrow bottom panel. v v I It is customary to lfurnish the boxesV to the tradeV as but resists such flattening out because of the stiffnessof;

The result is a tight fit between the side box, even though they are not equidistant in the flat blank.l The improved box in its preferred form incorporates trapezoidal side wallv portions which, somewhat similar to the construction of a mansard roof, assume-,anV

inclined position with respect to the side wall inthe set up box. Substantially triangular cell panel portions rise above the trapezoidal panel portions, and form anY angle with regard thereto, as( does the upper portion of a mansard ,roof with respectto the lower portion.

traetedsA tions of the` cell' structure below the 'peak 36 proper" (Figure 4) and above the fold lines 23 and 24. The endmost cell having normally a` diameter of-D1 can be enlarged by an amount d1 by tilting the endmost cell wall 55 outwardlyvin the `d-irection of Vthe arrow 456. This tilt vvinvolves a substantially arcuate motion about the apex points 25, 27. A can having a diameter larger than D1 but smaller than vD1 plus d1 can now readily -be inserted into the cell mouth to a level below thepeaks 36. An intermediate cell may also be distended, even though less than the amount d1, by urging the peaks 36 apart. The insertion of the cans is further facilitated by the fact that the distan-ce d1 is` measured-between the fold1 lines which form the corners of the polygon, which distance i is greater than the distance betweeny opposite sides ofthe Polygon- As the can moves 4down into the cell mouth, it must A' next clear the out edges 21 and 22. This is accomplished by temporarilyy increasing the slope of the trapezoidal panels and 34 with respect tothe lower side wall portions 12' and 14. 'Iihis action is illustrated in Figure 4 and results in an enlargement of the normal distance between the edges to a distance D3 suiicient to permit the can-chime to pass.

As soon as the can-chime clears the bottom edge 20 of the ycell walls the box structure by reasonof the inherent resiliency of the paperboard returns to a normal position in which the diameter between the edges 33 and 34 is reduced to D2 which is only slightly more than the diameter d of the can body. D2 is slightly greater than d by reason of the fact that one additional thickness of Y board lies on the inside of the side walls 12 and 14 after folding of the web structure about the diagonal fold lines `29, 30, 31 and 32 (Figure 4). The contraction of the cell opening is aided by the righting of .the endmost cell webs from the tilted funnel-forming position into upright position with respect to the base panel 11. Righting of the cell walls automatically causes opposite apex pointsl 25, 27 and 26, 28 to tbe drawn together. This reduces the slope of the trapezoidal panels 33 and 34 and causes the side walls 12 and 14 to be drawn together until the can `body is snugly-held about -its' diameter d.

During the final phase of the insertion of the-cans into the box structure the side walls-are temporarily bulged out immediately above the chime vapertures 44 and 45 until the can-chimes snap into the apertures.

The inserted cans are firmly held by the edges 46. A

supplementary or safety catch is provided by the bottom edges 20 of the webs which grasp the 4chimes if a can should accidentally slip out of engagement with the edges 46. n

The locking of the canchimes in the apertures 44 is accomplished without 'the gluing or Vstapling` operation required in conventional chime locking folding boxes employing `apertures of the type shown at 44.

A comparison of Figures l land 6 shows that ythe fold I drawn from the chime engaging-apertures 34 in which event the cell edges 20 become operativeras a safety lock. The distensibility of the box structure permits articles of dijferent diameters to be carried in the same box, as

may be desirable in the assembly of combination packages. Referring to Figure 7 it may be assumed that a slightly larger article is to be inserted into the right cell than into the left, the ldifference in size being suicient to present a problem in fitting the chime end into the locking aperture 44; This problem is readily overcome by the provision of ya supplemental slit 46 permitting the wall to are out slightly at the slit when the article is pressed down into seating position. r Whati'sclaim'edisi L s l.
