Definitions

  • This invention relates to a carton, and concerns in particular a carton of card or the like made by erecting a suitably cut, creased and folded blank.
  • Erectable cartons or boxes of the sort referred to generally as "cardboard boxes” (although in fact they can be made of materials other than cardboard), are of great value in the packaging industry, for they may be preformed then stored in their space-saving un-erected (collapsed) state, only being opened up (and usually further folded and interlocked) and erected into their use state immediately prior to their actual utilisation.
  • such a box or carton is manufactured from a sheet of the relevant material in a number of stages.
  • the sheet is cut and creased to form what is known as a "blank"; the cuts and creases both mark out the relevant portions of the carton - panels which will form the carton's front, rear and side walls, its top and bottom surfaces, and any necessary flaps and tongues and slots, and so provide the blank with the shape that will define the carton formed therefrom - and also are such as to enable the basically flat sheet to be folded in the way required to construct the desired three-dimensional carton.
  • the blank may be of the "base” type, with a central panel (to form the bottom of the carton) having wall and top panel extensions disposed around it, or it may be of the "peripheral” type, with a sequence of side-by-side panels (to form the walls of the carton) having base and top panels extending therefrom.
  • a "peripheral" construction commonly requires one flap-like part of the blank to be permanently affixed - by glue or staples, for instance - to another part (usually one of the areas of the blank defining a wall of the carton); the next, stage, then, is to effect this fixation, and the blank is conveniently designed so that this can be done with only a single fold of the blank, and in such a way that what is formed is a flat, easily storable, "collapsed" version of the carton (strictly speaking, this folded and affixed "pre-form” is better described as an "un-erected” version, but in the Art such pre-forms are conventionally referred to as "collapsed”). Finally, when required for use the folded and affixed blank is opened up and then further folded (along the provided creases) so as to move the various wall and top and bottom portions into their required carton-defining positions.
  • Figure 1 carton is erected from a blank which, in its collapsed state, has its floor/base portions folded upwards to lie against its inner wall surfaces, and upon erection these portions are encouraged to drop down into place, passing - as they do so - through the volume that is the inside of the carton.
  • Figure 2 "archive" carton is made from a comparatively uncommon type of blank which, in its collapsed state, has its floor/base portions extending down wards, to lie away from its inner wall surfaces, and upon erection these portions are pushed up into place, a movement which does not require them to pass through the internal volume of the carton.
  • the bottles may range in size from 250ml beer bottles through 75cl wine bottles up to 2 litre bottles of soft drinks, disposed in regular arrays of two, four, six, eight, nine, twelve, fifteen, twenty-four and more (usually as groups of 2x1, 2x2, 3x2, 4x2, 3x3, 5x2, 4x3, 5x3, 6x4 and so on).
  • the carton is indeed to be used for this type of purpose then it is convenient to provide it with interior space dividers - slotted card strips that fit together to make an appropriate array of rectangular cells into each of which a bottle fits - and thus to prevent the bottles when in situ rattling around in the box.
  • this invention provides a collapsed carton of the "archive" type, being erectable into a double-skinned carton having an inner and an outer box subsection each made from a set of panels, the base of the erected carton being formed from portions of a web of material extending in the collapsed state between the panels forming the inner and outer box subsections, these base portions, in the carton's collapsed state, extending down wards, to lie away from the inner wall surfaces of the panels forming the inner box subsection, and these base portions being, upon erection, pushed up into place without passing through the internal volume of the carton, wherein fixedly located in position to those panels forming the inner box subsection of the carton are spacer strips disposed to define a cellular array of spaces within the subsequently-erected carton.
  • the invention provides a carton - either a collapsed carton or an erected carton - of the "archive” type. By this is meant not that the carton need be exactly like any particular "archive” carton but that it is of this general type.
  • the blank for such a carton is usually an elongate oblong in overall shape, and has along one of its long sides those portions (or panels) which form the four side wall surfaces (the two ends and the left and right sides) of the inner section and along the other of its long sides those portions (or panels) which form the four side wall surfaces of the outer section, these two sets of four panel portions being joined by a matching set of four pairs (two sets of four) of "facing" trapezium portions (each pair mounted with the shorter of the two parallel sides together along a line that is the central long axis of the blank and the longer sides adjacent the related side portion), which trapezium portions fold, concertina-fashion and in an interlocking manner, to form the bottoms of the inner and outer box sections.
  • the carton - and thus the blank - can be of any suitable size.
  • an appropriate size - for the erected box - is roughly 12 1 / 2x9 1 / 2x14in (32x24x36cm) long-by-wide-by-deep, giving individual cells of about 3x3in (7.5x7.5cm).
  • spacer/divider strips Fixedly located in position within the part forming the inner section of the carton are spacer/divider strips disposed to define - to divide the interior of the erected carton into - a cellular array of spaces within the erected carton.
  • the spacer strips may be of any height, but will typically be conventional part- or whole-height strips of card slotted to enable them to be fitted together to define the required array of cells.
  • a 4x3 cell array is thus defined by two long strips (extending in the "4" direction) and three shorter strips (extending in the orthogonal "3" direction).
  • the strips may be located "fixedly" in any convenient way - it is preferred to give some of the strips flaps at each end which in use lie flush against the relevant strip-normal inside wall surfaces of the inner box section, and can be attached thereto (glueing is the preferred attachment method, possibly using a contact glue that holds them directly as the carton blank is assembled in its collapsed form, but stapling is a possibility).
  • glue is the preferred attachment method, possibly using a contact glue that holds them directly as the carton blank is assembled in its collapsed form, but stapling is a possibility.
  • Just which of the strips has the end flaps is generally immaterial - they can be on either or both the length-wise strips and the cross-wise strips - as long as sufficient strips have them to render the array stable.
  • the carton of the invention may be made from a sheet of any appropriate material (typically a fibre board such as a thin or thick, corrugated or plain card or board made from natural cellulose fibres, or even a wholly or partially synthetic material such as a plastic like a polythene or a polystyrene, or a fibre board coated therewith).
  • the divider strips can likewise be made from a sheet of any appropriate material (though, not having to take any significant stresses, the strip material may be lighter - thinner, and less strong - than the carton material). All this is well-known in the Art, and needs no further comment here.
  • the blank of Figure 1A is of interest merely for the flaps (11), which in the erected carton of ( Figure 1B) from the base thereof.
  • these flaps are folded up between the walls (12) of the carton, and as the erection process takes place they drop down into place through what is becoming the volume enclosed by the carton.
  • this space was already taken up by an (unfolding) set of spacer/divider strips the flaps would be unable to fold down into place, and the carton could't be properly erected. Accordingly, with this type of carton any divider strips to be used therewith must be positioned after the carton has been erected; they cannot be fixedly located in place within the collapsed version.
  • the blank and carton of Figure 2 is of that general type on which the present invention is based. It is a double-skinned carton, having inner and outer box sections (11,12).
  • the blank is an elongate oblong, and has along one of its long sides those portions (or panels: 11a,b,c,d) which form the four side wall surfaces (the two ends and the left and right sides) on the inner section and along the other of its long sides those portions (or panels: 12a,b,c,d) which form the four side wall surfaces of the outer section, these two sets of four panel portions 11,12 being joined by a matching set of four pairs (two sets of four:111a,b,c,d; 112a,b,c,d) of "facing" trapezium portions (each pair - 111a/112a, 111b/112b, etc - mounted with the shorter of the two parallel sides together along a notional line (15) that is the central long axis of the blank and with the longer sides adjacent
  • Figures 3 and 4 show - in diagrammatic form - how the double-skinned carton of Figure 2B is erected. From its collapsed form (much like that of Figure 5B discussed hereinafter) it is opened out to give the Figure 3 form, in which the inner box 11 is positioned "above" the outer box 12, supported on the four pairs of trapezium sections (111a,112a, etc), and then the inner box is simply pushed down into the outer box, the trapezium sections folding down, in a concertina, interlocking fashion, to form the base of the carton.
  • Figures 5A,B show a double-skinned carton like that of Figure 2B but with full-height divider strips (as 51) fixedly located therewithin.
  • the crosswise strips 51 c reach out to (and may touch) but are not fixed to the walls they extend between, though they are located on the lengthwise strips.
  • Figure 5A shows the carton in its fully-erected form; the top plan view of Figure 5B shows what it looks like in what is essentially its collapsed form (it is in fact "opened out” slightly to show the divider strips 51 therein).
  • Figure 6 shows how the blank of Figure 2A is folded, and provided with divider strips, to form the collapsed blank of the invention.
  • the blank of Figure 6A - which is the same as the blank of Figure 2A - is an elongate oblong, and has along one of its long sides those portions (or panels: 11a,b,c,d) which form the four side wall surfaces (the two ends and the left and right sides) on the inner section 11 and along the other of its long sides those portions (or panels: 12a,b,c,d) which form the four side wall surfaces of the outer section 12, these two sets of four panel portions 11,12 being joined by a matching set of four pairs (two sets of four:111a,b,c,d; 112a,b,c,d) of "facing" trapezium portions (each pair - 111a/112a, 111b/112b, etc - mounted with the shorter of the two parallel sides together along a notional line (15) that is the central long axis of the blank and with the longer sides adjacent the related side portion).
  • the longer sides of the outer section trapeziums 112 are joined to the relevant outer box wall sections 12 by a fold line (61), and the first step is to fold the wall sections 12 underneath so that they lie behind the trapezium portions 112.
  • This state is shown in Figure 6B (in an actual production line the sections 11, 111 and 112 would normally be folded over on top, and the carton formed in an "inverted" state).
  • the pre-prepared collapsed divider strip assembly (62) is laid in position along inner box walls 11 b and 11 c - which are going to become part of the inner surface of the inner box 11 - and the relevant end flaps 52 are glued to the inner surface 11 b .
  • the right-hand (as viewed) end of the blank - the four "d" sections - is then folded over on top (and is glued to the other strip end flaps 52), to give the state shown in Figure 6D.
  • the left-hand end (as viewed) of the blank - the four "a” sections - is folded over on top of the strips, and the main flap 16 is glued into place on the outside surface of the outer box wall 12 d .
  • Erecting the carton is essentially exactly like erecting the more conventional carton of Figure 2B, and as shown in Figures 3 and 4.
  • the carton is opened out from its fully-collapsed state (Figure 6E), passing through a partially-erected state (Figure 5B), into the "open" - rectangular - state like that of Figure 3.
  • the inner box 11 is then simply pushed down into the outer box 12 (as in Figures 4), the trapezium portions folding down to form the double-skinned base as this is done.
