Definitions
- an improved container is provided. Although it is particularly adapted for shipping and storing material, such as synthetic rubber which has the aforementioned cold flow characteristics and hence exerts great pressure against the container walls, it may be employed for the packaging of other types of material which require a container of great strength.
- the container is desirably made of a plurality of plies of paperboard, advantageously so-called double wall corrugated paperboard.
- the respective plies have wall panels which are adhesively laminated to each other to form container walls of multi-ply substantially uniform thickness throughout.
- the plies are so arranged that so-called manufacturers joints such as corner tape, stitching or glue flaps are not required to fasten end edges of panels together, as the panels of the plies provide at least an integral corner construction at each of the upright corners of the container.
- the container walls are of at least three-ply thickness with each upright corner of at least two-ply thickness, which provide not only bulge resistance but also marked stacking strength.
- At least one of the plies advantageously comprises a plurality of pads; each pad having upright end edges and wall panels integrally connected along an upright hinge connection line positioned at an upright comer of the container.
- the end facing edges of adjacent pads are adjacent to but spaced apart at another corner, being free of attachment whereby a gap is provided between such edges; and the space between these facing edges is closed by an integral corner of a contiguous ply.
- a special method for forming the container from a collapsed state of the plies comprising adhesively uniting strips having wall panels which form an inner ply and an intermediate ply, and adhesively uniting pads to the outer faces of the intermediate ply; each pad being composed of wall panels integrally connected together along a corner forming hinge connection line.
- the pads are so positioned that a hinge connection line thereof is at a comer of the container and the ends thereof adjacent to but unsecured to each other at another comer of the container.
- the invention has as its objects among others, the provision of an improved multi-ply container construction having walls of substantially uniform thickness throughout and in which the manufacturers joint commonly employed for securing ends of panels together at an upright comer of the container, is not required, which has great strength including stacking strength, and is of economical and simple construction, and-the provision of an improved method for forming such container.

- FIG. 16 is a similar view illustrating the relationship of the outer ply to the remaining plies, and;'
- FIG. 17 is an enlarged horizontal cross section of the container.
- FIGS. 1 through 8 disclose an embodiment of the invention in which the container has four upright walls and is rectangular in cross section; the walls being formed of three plies and are of uniform thickness throughout. Desirably the respective plies are of double wall corrugated paperboard, although solid paperboard of any other suitable type of strong sheet may be employed.
- An inner ply 2 of the container comprises a continuous strip of integrally connected wall panels 3, 4, 6, 7 and 8 as can be seen from FIG. 1, which are integrally hinged together along respective hinge connection lines 11.
- End panels 3 and 8 of the strip are not full wall panels but in the setup container which is rectangular in cross section, end edges 12 of these end panels face each other, being unattached to each other but in substantial abutment to form substantially an abutment joint 13.
- Bottom closure flaps 16 are hingedly connected to the lower edge of inner ply 2 to form a bottom closure in the setup container.
- the blank from which inner ply 2 is formed is known in the trade as a half slotted container (I-ISC) blank.
- Adhesively bonded to the outer face of inner ply 2 is a plurality of L-shaped pads 17 which provide an intermediate ply of the container; each pad being composed of a continuous strip of wall panels 18 integrally hingedly connected along an upright hinge connection line 19 positioned substantially in alignment with an upright corner A of the container.
- Each panel 18 is substantially a full wall panel, being of such length that its end edge 21 is located closely adjacent another corner B.
- the adjacent facing edges 21 of adjacent panels 18 are also unsecured together with a space or gap 21' existing between such facing edges 21 of adjacent pads. From FIG. 6 it will be noted that the abutment joint 13 of inner ply 2 is covered or closed by a panel 18 of a pad 17.
- a pair of L-shaped pads 22, each pad being similar to an intermediate pad 17, forms an outer ply of the container and is adhesively bonded to outer faces of pads 17 with the upright integral hinge connection line 23 of each pad 22 overlying the space 21 at a corner between the adjacent edges 21 of intermediate pads 17.
- the upright end edges 24 of adjacent outer pads 22 form a gap 24 at the comer A defined by an integral hinge connection of an intermediate pad 17.
- the container walls are all of uniform thickness, and comprise three plies laminated together by adhesive.
- Each upright corner of the container is of two-ply thickness making for strength even though spaces 21' and 24' are formed between the free or facing unsecured edges of adjacent pads. Also, in each instance corner spaces 21' and 24' are covered or closed by an integral corner hinge connection of a contiguous ply.
- abutment joint 13 of inner ply 2 is located between adjacent corners of the container, it could also be formed at any corner instead but then in the embodiment thus far described, there would only be one-ply thickness at one corner and two-ply thickness at the remaining three comers.
- a top closure formed of closure flaps similar to bottom flaps 16 may be provided if so desired, or the top end may be closed with a paperboard cap 26 as shown in FIG. 5. Also, flaps 16 may be eliminated and the bottom closed with a cap. For the type of product for which the container has found special utility, it is usually transported and mounted on a pallet because of the heavy weight of the contents. Hence, a single-ply bottom closure formed by flaps 16 is all that is required for bottom strength because of the reinforcing effect of the pallet.
- the container is about 41 inches in height and 33 X 34 inches (inside dimensions) in rectangular cross section.
- the plies are made of conventional double wall corrugated paperboard comprising two corrugated mediums 27 adhesively bonded to an intermediate paperboard liner 28 and to outer liners 29 as can be seen from FIG. 2.
- a suitable weight of each of the corrugated mediums is about 26 pounds per thousand square feet, and a suitable weight for each of the liners is about 42 pounds per thousand square feet.
- the plies are desirably arranged so that at least two plies have their corrugations run transversely with respect to each other.
- the corrugations of the outer ply desirably extend vertically, the intermediate ply horizontally, and the inner ply vertically.
- the intermediate ply corrugations may extend vertically; and either of the inner or outer ply corrugations or both may extend horizontally.
- FIGS. 7 and 8 illustrate the method of making the container.
- the continuous strip which provides inner ply 2 is collapsed to bring panels 8 and 3 together; and form abutment joint 13.
- Adhesive is applied to the inner faces of pads 17 which provide the intermediate ply, and they are secured to the outer faces of intermediate ply 2 with a hinge connection line 19 of each pad 17 in substantial alignment with an integral hinge connection line or corner 11 of inner ply 2, thus forming a laminated twoply construction.
- the two-ply construction is collapsed from the position shown in FIG. 7 to the position shown in FIG. 8 wherein the hinge connection corner 11 between panels 7 and 8 and the hinge connection corner 11 between panels 4 and 6 are on opposite faces of the two-ply construction.
- Outer pads 22 with adhesive on their inside faces are then adhesively united to the thus folded two-ply structure with an integral corner 23 of each pad in substantial alignment with a corner 11 ofinner ply 2 over the space 21' between adjacent pads 17.
- the united three plies are then run through a compressor to firmly bond all the plies together, thus forming the described container when the structure is set up from collapsed state.
- FIGS. 9 through 13 illustrate a modified construction which is substantially the same as that described except that the intermediate ply 31 is formed of a continuous strip, and the abutment joint of the inner ply is at a comer.
- Intermediate ply 31 comprises four hingedly connected full wall panels 32, 33. 34 and 35 having hingedly connected closure flaps 36 at top and bottom.
- Inner ply 37 also comprises four full wall panels 38, 39, 41 and 42.
- adhesive is applied to the inside face of intermediate ply 31, and end panels 38 and 42 of inner ply 37 are turned inwardly along end score lines 43 and secured to panels 33 and 34 of intermediate ply 31, with their end edges 44 in substantial alignment with the central score line 46 ,of intermediate ply 31.
- end panels 32 and 35 of intermediate ply 31 are turned inwardly and secured to the outside faces of panels 39 and 41 of the inner ply, thus forming a two-ply construction.
- the described construction also results in at least two-ply thickness at each corner. Also, all gaps and joints between adjacent wall panels at each corner are covered by an integral corner of a contiguous ply. Since the modification thus described has a plurality of pads forming only the outside ply, the two pads of the intermediate ply of FIGS. 1 through 8 are eliminated, it has the manufacturing advantage of enabling the structure to be assembled faster in the box plant.
- closure flaps 36 are provided at both top and bottom but caps of the type shown in FIG. 5 may be employed in place of either set of bottom or top closure flaps.
- the closure flaps are on the inner ply, they may be provided on the intermediate or outer ply if so desired, and vice versa with respect to the modification of FIGS. 9 through 13.
- FIGS. 15 through 17 illustrate schematically such construction for a hexagonal crosssectionally shaped container.
- the inner ply comprises a continuous strip of hingedly connected panels 51, the end panels of which are in substantial abutment to provide abutment joint 52.
- An intermediate ply is formed of two pads 53 of a strip of three hingedly connected panels 54, the end edges 56 of which are unattached and extend to a corner of the container.
- the outer ply also comprises a pair of pads 57 similar to pads 53, the end edges 58 of which extend to an integral corner 59 of intermediate pad 53 and are unattached together at such comer.
- manufacturers joint is not required, and there is at least two-ply thickness at all comers of the container with gaps between adjacent end edges of adjacent panels of a ply covered by an integral corner of a contiguous ly.
- a multi-ply container having upright comers and walls composed of a plurality of plies laminated together, at least one of said plies being a continuous strip of integrally connected panels with all adjacent panels hingedly connected together except at the edges of the end panels, at least another of said plies comprising a plurality of separate pads nonintegral with any of the other components of said container, each pad having upright end edges and wall panels integrally connected along an upright hinge connection line positioned substantially in alignment with an upright corner of the container, and the length of each pad being such that each end edge thereof is located at another corner of the container with a space between the end edges of adjacent pads.
- a ply contiguous to said another ply comprises adjacent panels integrally connected along an upright hinge connection line closing each of said spaces.
- the multi-ply container of claim 2 comprising at least three plies a first of which being an inner ply comprising panels hingedly connected together except at the edges of the end panels thereof, said edges being unattached and forming substantially an abutment joint, a second of said plies is an intermediate ply which covers said abutment joint, and a third of said plies is an outer ply which comprises said plurality of pads.
- a multi-ply container having upright corners and comprising an inner ply, an intermediate ply and an outer ply adhesively bonded together, said inner ply being composed of a plurality of hingedly connected wall panels the end panels of which have upright facing edges unattached to each other, said intermediate ply covering said facing edges of said inner ply and having at at least one comer of the container upright edges which are unattached to each other, said outer ply including a plurality of wall panels integrally connected along an upright hinge connection line substantially in alignment with and covering a corner of the container, end edges of adjacent panels of said outer ply being unattached to each other at a corner of the container, and said container having at least twoply thickness at each corner thereof.
- a multi-ply container composed of at least three plies adhesively bonded together and having upright walls and an upright corner construction of two-ply thickness provided by two of the plies, the remaining ply having adjacent end edges unattached to each other at said corner.
- a multiply container comprising at least three plies laminated together, a first one of which being an inner ply comprising panels hingedly connected together except at the edges of the end panels thereof, said edges being unattached and forming substantially an abutment joint, a second of said plies being an intermediate ply which covers said abutment joint, and a third of said plies being an outer ply comprising a plurality of pads with each pad having upright end edges and wall panels integrally connected along an upright hinge connection line positioned substantially in alignment with an upright corner of the container, the length of each pad being such that each end edge thereof is located at another corner of the container with a space between the end edges of adjacent pads, and a ply contiguous to said pads which form said outer ply comprising adjacent panels integrally connected along an upright hinge connection line closing each of said spaces between such pads.
