Definitions

  • This invention relates to an improved packaging carton made from stiff but foldable board material and in particular to a carton having an easy-open tear strip defined by at least one length of reinforcing material applied to the board material.
  • the invention also relates to a blank formed from a sheet of board material incorporating a reinforced easy-open tear strip, the blank being cut from the board material in a manner to sever the length(s) of tear strip reinforcing material whereby part only of the incorporated material is available for its intended function of tearing board material in a carton folded up from the blank.
  • the invention in its carton aspect, relates to a carton formed from stiff but foldable board material having at least one length of reinforcing material applied to the board material to define an easy-open tear strip delimiting first and second carton parts which parts are hingedly connected following use of the tear strip, which carton is characterised in that said at least one length of reinforcing material is longitudinally splittable and is cut through along a line transverse to its longitudinal direction, whereby on use of the tear strip, the line of cut represents the end of the tear, a split length of at least one of the torn lengths up to the line of cut providing edge reinforcement on at least one of the parts.
  • the residue of the said at least one length serves as reinforcement for the hinge connection of the two parts.
  • the invention in its blank aspect relates to a one piece blank of stiff but foldable board material designed to be erected into a carton whose format can be changed by use of a tear strip to leave a carton base with a hinged lid, said blank including at least one length of reinforcing material applied to the board material to reinforce the tear strip, which blank is characterised in that said at least one length of reinforcing material is longitudinally splittable and extends from side to side of the blank but its use as a tear strip is limited to part only of its length by virtue of at least one cut in the board material which extends transversely across the at least one length intermediate its ends, the residue of the torn length of reinforcing material serving as reinforcement for edges of the lid.
  • the board material is a pluri-ply corrugated paperboard.
  • the reinforcing material is applied to the paperboard during its manufacture on a corrugator and conveniently is incorporated between plies thereof.
  • a convenient reinforcing material is a tape known under the trade mark "Sesame” (available from Sesame Industries Ltd. of Quebec, Canada) which is fibre-based and incorporates a heat-sensitive adhesive.
  • the invention has particular utility in the provision of a fully closed parallelepipedic carton intended to contain a liner for packaged contents which when opened leaves a lid hinged to one wall of the carton for easy reclosing and access to the packaged contents via the openable lid.
  • the liner can be a rigid inner receptacle, also erected from stiff but foldable board material, which on opening of the lid reveals an upstanding rim around which side regions of the lid bear as the latter is reclosed.
  • the rigid inner receptacle can contain a plastics bag in which the packaged contents are stored for use as required.
  • Handle openings can be provided in the carton walls below the level of the tear strip and suitably, in the case of a right parallelepipedic carton, it is the two walls adjacent to the wall providing the reinforced hinge connection which have handle openings.
  • Such handle openings can be reinforced with a further length of reinforcing material applied at the same time as that used for the tear strip.
  • the inner receptacle can provide a barrier preventing finger contact with the bag through the openings provided for carrying the carton.
  • a particularly preferred form of rigid inner receptacle has three superimposed layers of board material lining each carton wall provided with a handle opening, the two outermost layers of which have handle openings coinciding with the respective handle opening in the carton wall, but the innermost layer of which has no such opening and protects the bag from contact by a hand using the aligned handle openings to carry the carton
  • the one-piece blank 10 of Figure 1 is shown from the inside and is intended to provide the outer casing of a carton. It is cut and creased from a sheet of double-faced corrugated paperboard (the flutes of the central corrugated ply running in the direction of the arrows A) to exhibit external side wall panels 11, 12, 13 and 14, each provided with top flaps 11a to 14a and bottom flaps 11b to 14b.
  • the wall panels are delimited by creases 15, 16 and 17 extending in the flute direction and the flaps are delimited by other creases (unnumbered) extending normal thereto.
  • a narrow gluing tab 14c is formed as an extension of panel 14.
  • Carrying holes (or precursors thereof) 18 are provided in the wall panels 11 and 13.
  • Figure 2 shows (from the inside) the blank 10a for a rigid inner receptacle for the casing erected from the blank 10 of Figure 1.
  • the preferred board material is double-faced corrugated paperboard and the arrows A indicate the direction in which the flutes of the central corrugated ply run in the board.
  • the blank 10a exhibits a central base panel 19 with outer side wall panels 19a and 19b connected thereto via respective creases 22 and 23 extending parallel to the flute directions A, a left wall panel 20 and a right wall panel 21, linked to the central base panel 19 by respective creases 24 and 25 extending normal to the directions A.
  • Inner sidewall panels 21a and 21b are connected by respective creases 26 and 27 to the wall panel 21 and intermediate sidewall panels 20a and 20b are connected by respective creases 28 and 29 to the wall panel 20.
  • Four further carrying holes 30 are formed one in each of the sidewall panels 19a, 19b and 20a, 20b. No carrying holes are provided in the inner sidewall panels 21a and 21b.
  • the six sidewall panels 19a to 21b are bent up through 90° relative to their respective base and wall panels 19 to 21 and then the two outer U-shaped structures so formed are each bent inwardly about respective creases 24 and 25.
  • the three creases 22, 26 and 28 and the three creases 23, 27 and 29 are staggered one with respect to the others to allow the three U-shaped structures to combine to form an open-topped right parallelepipedic carton liner having three thicknesses of blank material on two opposite edges of the base panel 19 and a single thickness of blank material (i.e. the left and right wall panels 20 and 21) on the other two opposite edges of the base panel 19.
  • the folding arrangement described leaves two carrying holes 30 aligned in each of the triple thickness sidewalls but since the sidewall panels 21a and 21b of these triple thickness walls are innermost in the inner receptacle, the holes 30 do not extend completely through the sidewalls of the inner receptacle.
  • the preferred material 3 is made up of an 11 mm wide strip of "Sesame" tape located between the outer facing sheet of the board material and the corrugated ply and an 11 mm wide strip located on the face of the inner facing sheet which faces away from the corrugated ply to lie symmetrically behind the first mentioned strip.
  • the material 3 i.e. both tapes
  • the tab 31 diagonally severs all but a narrow central strip of both tapes (e.g. a 3 mm wide strip) whereby pulling on the tab 31 starts a longitudinal tear in both tapes which results in the central part of each tape and the board material sandwiched between such central parts being removed from the blank (see also Figure 12).
  • blank 10a is erected into the inner receptacle as described above and this is located open-top up inside the tube erected from blank 10 when gluing tab 14a is secured to the outer edge of panel 11 and the bottom flaps 11b to 14b are folded in and secured together in conventional manner.
  • the carton is now ready to receive the contents to be packaged therein and these are disposed in the inner receptacle either directly or after locating a flexible bag (e.g. of plastics material) within the receptacle. After adding the required volume of contents (and closing the bag if such is being used) the top flaps 11a to 14a are secured together to close the carton.
  • a flexible bag e.g. of plastics material
  • Figure 3 shows the blank 10 of Figure 1 and the blank 10a of Figure 2 erected into a closed carton 35. This is the format in which it would be passed to the end user.
  • Figure 4 shows the carton 35 in its other format ready for use. Pulling on the tab 31 causes the reinforcing material 3 to tear open the carton around three of the four sides as far as the cut 32. This action divides the carton into a base 36 and a lid 37 hinged about line 34.
  • the tape widths left adhering to the material of blank 10 on either side of the removed central regions provide reinforcement on each side of the tear.
  • One of these sides represents the three edges of the lid 37 and this reinforcement is valuable in resisting wear and tear on the edges of the lid as they rub against the upper extremity of the inner receptacle when the lid 37 is hinged open or hinged back into its closed condition. Since the contents packaged may well be used in small amounts on many different occasions, reinforcement of the lid edges is a valuable advantage which results from the invention.
  • a further advantage is that the line of the hinge in panel 14 is reinforced by the unused lengths of the reinforcing material 3.
  • the hinge line 34 can be defined by a line of perforations (sometimes known as a "matrix bend") to improve flexibility in this region, the residues of the reinforcing material retaining full integrity of the board material despite the weakening effect of such perforations.
  • each hand hole available in panels 11 and 13 consists of one hole 18 and two holes 30 providing three wall thicknesses to accept the carrying load on each side of the carton.
  • the holes 18, 30, 30 do not extend to the interior of the inner receptacle (by virtue of the unapertured sidewall panels 21a and 21b) thus meeting the requirement for bagged transport of certain "dangerous goods" that hand contact with the bag must not occur.
  • the unapertured sidewall panels 21a and 21b also allow packaging of particulate materials without an inner bag.
  • Figures 5, 6 and 7 illustrate a second embodiment of carton according to this invention.
  • similar reference numerals with the addition of 100 will be used to indicate similar integers and the description will be restricted to the areas of difference.
  • wall panel 112 has the precursor of a lid closure tongue 50 formed therein and two tabs 131a and 131b flank this.
  • the cut 132 is formed between panels 113 and 114 on the crease line 117.
  • the internal wall panels 119, 120 and 121 are connected to blank 110 and lack top and bottom flaps, but panel 120 includes a slot 51 (cut through the lengths of reinforcing material 130) to receive the tongue 50 in the second format of the carton.
  • Figure 6 shows the carton 55 erected from the blank 110 of Figure 5 (e.g. to receive photographic materials in sheet form).
  • Figure 7 shows the format change available when the tabs 131a and 131b are pulled to activate tear strips to left and right of the tongue 50.
  • the cut 132 stops the tear at the right-hand back corner of the carton 55 leaving a lid 53 hinged to a carton base 54, the hinge line occurring along the (unused) lengths of material 130 which thus reinforces the hinge.
  • the lid 53 can be reclosed by locating the tongue 50 in the slot 51.
  • the lengths of reinforcing material 130 extending between the tabs 131a and 131b acts to reinforce a central region of the tongue 50.
  • the residues of the tear strip left around the lid reinforce this edge against wear and tear as previously described.
  • Figures 8 to 11 show a third embodiment of blank and carton according to this invention and for the description of this embodiment, the reference numerals of Figures 1 and 2 with the addition of "200" will be used for equivalent integers.
  • Figure 8 shows the outer blank 210 of a double-walled heavy-duty powder case (of 72 litres capacity), the inner blank 210A being shown in Figure 9.
  • the outer blank 210 has the tear strip reinforcing material 230, the cut 232 being formed on crease 215 between panels 211 and 212.
  • the blank 210A has four rectangular inner wall panels 219 to 221 and 63, an edge connecting panel 64 being provided to link panels 63 to 219.
  • Figure 10 shows a carton 60 in its first format, erected by locating the blank of Figure 9 inside the blank of Figure 8 and folding over the top and bottom flaps 211a to 214a and 211b to 214b.
  • Figure 11 shows the carton 60 in its second format, created by using the tear strip through pulling on tab 231.
  • the unused tear strip reinforcing material 230 reinforces the hinge of the lid 61 on the base 62 of the carton and residues of the torn lengths of tear strip reinforce the edges of the lid protecting the same against abrasion caused by repeated opening and closing of the lid 61 on the base 62.
  • Figure 12 shows a section of 3-ply corrugated board material 70 being severed by a tear strip 71.
  • the tear strip 71 is created in the manner described above by applying an inner strip 72 and an outer strip 73 of longitudinally tearable, tape material, respectively, to the concealed surface of the outer ply 74 and the exposed surface of the inner ply 75.
  • the tab 76 is cut diagonally along lines 77a and 77b to leave a central region of both tape strips 72, 73 unweakened by the cut lines 77a, 77b and it is this central region of both tapes which creates the narrow tear strip 71.
  • the inner strip can be narrower than the outer and need not then be longitudinally tearable.
  • a single length of reinforcing tear strip material can also be used and if this is partially severed by the cuts defining the narrow end of the tear tab 31, 131, 231, it would still leave reinforcing material around the edge regions of the lid.
  • Figure 13 shows a two-part clasp 70 fitted to provide means to securely reclose the carton of Figure 4 after first opening.
  • the clasp 70 can be housed within the carton 35 in the first use format shown in Figure 3 (e.g. on top of a bag containing the packaged product) whereupon the user can remove it on opening and secure one part 70a to the lid 37 and the other part 70b to the base 36.
  • the clasp 70 can take many forms e.g. it could be a lockable catch of metal or plastics material (such as used on a briefcase or suitcase) or a simple snap fastener of the kind illustrated in Figure 13.
  • the two parts of the clasp 70 can be snapped into pre-formed apertures provided in the blank 10, 110, 210 and such locating features are illustrated schematically by the dotted lines 71, 72 in Figure 1.
  • the clasp parts 70a, 70b can have wing nuts or the like screw fastening devices to clamp the parts in place.
  • a single clasp 70 is usually sufficient but if required (e.g. to ensure opening of the carton requires the use of two different keys) more than one clasp can be provided in the closed carton and more than one set of precursors for the locating position of the clamps provided on the blank.
