- Carton 10 shown *n Fig i is formed from a single plank 14
- the blank 14 is configured as shown in Fig. 2 and includes at least four primary panels for forming the carton 10
- the primary panels of the blank 14 are a top wall 24, a first side wall 20. a bottom well 18 and a second side wall 22. These panels 24, 20, 18 and 22 are NngecHy connected sn senes one to !he next along fold lines 30. 32 and 34.
- the top wall 24 is hmgedly connected to the first side wall H ) by fold line 30.
- the first side wall 20 Is then hsngediy connected to the bottom wall 18 by fold line 32.
- the bottom wall 18 is then hingeoly connected to the second side wall 22 by fold line 34
- Each of rhe panels 18, 20, 22 and 24 Is provided with opposing end flaps that are connected to the respective pnmary panel along transverse fold lines 36 and 38.
- Fold isnes 36 and 38 each extends substantially rhe full length of the blank 14
- the opposing end flaps include opposing lower end flaps 52 and 54, opposing uppe? ' end flaps 56 and 58 and opposing sloe end flaps 60, 62: and 64, 66
- the end flaps 52, 56, 60 and 64 extend outward from the transverse fold line 36 wh ⁇ e- the end flaps 54, 58, 62 and 66 extend outward from the transverse fold line 38,
- Side end flaps 60 62, 64 and 66 Include medial fold lines TO, 72, 74 and TO, respectively.
- the media! fold line of each side end flap dlv-des that end flap Into a ⁇ a-r of proxsmal and distal portions 60a ; 00b, 02a, 62b, 64a, 64b; and 66a, 06b.
- the width ⁇ or horizontal transverse size) WI of each of the distal portions 60b, 62d, 64b, and 66b is greater than the width ⁇ o? horizontal transverse size ⁇ VV2 of each of the proximal portions 6Oa 1 62a, 64a, and $6a.
- the distance between transverse fold line 36 or 38 and each medial fold ⁇ ne ⁇ s less than the distance between that medial fold line and the free end edge of the respective drsfal portion
- the articles “A” are preferably stand-up pouches which may he deformahie and are made from a flexible material such as a ptastlc-aiuminum laminated film.
- each article “A” In me empty condition, each article “A” ss flat in the billed condition, each article “A” has a fiat bottom and generally rectangular front and rear panels. The front and rear panels extend from the bottom into a mutual contacting and sealed relationship at the top of the pouch.
- the bottom of each pouch is In the form, generally, of a hexagon.
- Each side wall of each pouch has a generally triangular configuration with its base being at the bottom. Therefore, the bottom of each pouch is considerably wider than the top when viewed from the side .
- the side end flaps 60, 62 ; 64 and 66 are folded upward along transverse fold lines 36 and 38 as shown in Fig 3.
- Side end fleps 60, 62, 64 and 66 are then folded along the medial fold lines 70, ?2, 74 and 76 respectively so that the proximal portions 60a, 62a, ⁇ 4a and 66a remain In the vertical positions and me distal portions 60b.
- each distal portion extends downward at an angle toward the adjacent side wall 20 or 22
- each distal portion when in the bracing position extends between the respective proximal portion and the adjacent side wall such that it is disposed obhquely with respect to either the respective proximal portion or the adjacent -side wall
- Each of the side end flaps thus form part of a tubular corner column having a triangular cross section; each triangular corner column is formed ;n part from the respective side end flap and in part from a portion of the adjacent side wall.
- the corner columns may be completed at the later stage of the carton- forming process, in such en alternative process, the distal portions 6Qb. 62b, 64b and 66b may be merely pre ⁇ folded along the medial fold lines ?0 ⁇ 72. 74 and 76 with respect to the verts call y-disposed proximal portions 60a, 62a : 64a ; 68a to the extent that the distal portions lie somewhat inwardly of the blank to assume a pos ⁇ or ; spaced above the adjacent side walls 20 and 22.
- the pre-folded distal portions are subject to the load of the articles t boe placed on such distal portions during the article-loading step and will thereby further folded to reach the respective bracing positions where the disial portions provide part of the respective corner columns
- each side end flap ss not glued to, and thereby remains detached from, the adjacent side wall
- the corner columns are held s ⁇ their erected tubular forms by means of the a ⁇ .;cles received in the carton, as will be described In more details later.
- the pouches '' A" at the ends of each row are placed on the corner columns respectively and thus move and/or hold the distal portions 60b, 62b, 64b and 66b down in their bracing positions wherein the respective free end edges of the dislai portions are pressed against and thereby frictionally fsxed on, the adjacent side walls 20 and 22.
- the free end edges therefore, do not require any glue, adhesive or any other securing means (such as staples and adherent rapes) to be attached to the side walls 2O 1 22 and yet the corner columns are retained in their respective erected tubular forms Following the above step, the side walls 20 and 22, are Folded toward each other along fold lines 32 and 34 in order to further erect the carton.
- Fig. 4 mechanical means may be used to help hold the pouches "A” in piece during this step.
- This further erecting step eventually brings the side walls 20, 22 into (he upright positions as shown sn Fig 5.
- the pouches "A” in one row become nested with the pouches "A” in the other SOW in such a manner that the bottoms of the pouches sn the one row face the iops of the pouches in tne other row.
- the bottoms of the pouches in the left-hand side row and Hie tops of the pouches in the right-hand side row rest upon the bottom wall 18.
- Fig. 1 illustrates the edge flap 80 as being glued io the outside surface of the top wall 24, however, it may alternatively be glued t moe snslde surface of the top wa ⁇ 24 depending on the carton-forming process.
- the upper and lower end fiaps 56 and 52 are folded downward and upward respectively and giued io the adjacent proximal portions 60s and 64a io provide an end closure structure for closing she rear end of the carton.
- the upper and lower end fiaps 58 and 54 are also similarly folded end secured to the adjacent proximal portions 62a and 66a to provide the other end closure structure for closing the forward end of the carton.
- a fuHy erected carton ;$ thus provided as shown in Fig. 1.
- the pouches "A" occupy a minimum space because the pouches "A" in the one row are nested with those of the other row and also because tne pouches sn each row are in the overlapping condition
- FIg. 6 is a fragmentary ⁇ oss-seeiio ⁇ ai view of the certon of Fig I and shows the condition of the inside of the fully erected carton
- the end ctosure structure at the forward end of the carton ss formed from the side end fiaps 62 and 66 and the upper and iower end flaps 58 and 54.
- the distal portions 62b and 66b of the side end Haps 8? and 66 extend divergency from me proxuna?
- the end closure structure a* the rear end of Hie carton is formed from -he side end fiaps 60 and 64 and the upper as ⁇ lower end flaps 56 and 52, and thus the rear buttress arrangement that includes the other two triangular tubular columns ;s provided at least in part by the rear end closure sin.iCiure The distai portions 62b.
- the Ie-Id fines 3O 1 32, 34 and 82 form the horizontal longitudinal edges of the carton 10 while the transverse fold lines 36 and 38 form she vertical edges and horizontal transverse edges of ; he carton 10
- the side end fiaps and the upper and lower end Haps at each end of the carton provide the respective end closure structure.
- the distai portions of the side end flaps of each end closure structure extend divergently from the corresponding proximal end portions toward the adjacent side walls This is best shown in Fig. 6 wherein the distal end portions &2b and &6b extend into the internal space of the carton at about 45 degiees with respect th teo proximal portions 62a and 66a
- the distal portions of each end closure structure extend all the way between the top and bottom walls 24 and 18 and provide a buttress arrangement for enhancing the stacking strength of the carton.
- each distal portion is in direct abu ⁇ meni on the top and bottom walls 24 and 18 respectively to be able to bear the load transmitted from the top and bottom walls when the carton is arranged wsm like cartons ;n a stacked condiilon
- each distal portion is greater rhan the horizontal transverse ss?.e or width of rhe corresponding proximal portion.
- This arrangement allows the disial portions to provide me sturdy tubular columns for achieving greater stacking strength
- the tubular columns also provide greater structural integrity to the carton 10 Because o ⁇ the tubular columns the carton 10 may sustain greater weights when stacked wsthin a group of like cartons.
- FIG. 7 An alternative method of forming the carton of Fig 1 is illustrated sn Figs 7 - 9 A partially erected carton 12 as shown in Fig. 7 may he formed from the blank 14 of Fig. 2. The various panels, folds, etc have already been described.
