Definitions

  • This invention relates to blanks for containers, and concerns in particular a blank and a sleeve-like container made therefrom that is suitable for use as part of a containerisation system that may be of value in, for example, the packaging of fluids - especially gels and liquids - contained within a plastic bag, particularly such a bag in the form of a water-soluble envelope.
  • one or more of such pouch/bag combinations are typically retained within an outer shipping carton, commonly of corrugated fibreboard or the like, that is either roughly the right size to hold the one (or more) pouch/bag combination or is partitioned (rather like a wine box) to keep each pouch/bag relatively secure, and to provide additional strength and some protection against puncturing or tearing.
  • an outer shipping carton commonly of corrugated fibreboard or the like, that is either roughly the right size to hold the one (or more) pouch/bag combination or is partitioned (rather like a wine box) to keep each pouch/bag relatively secure, and to provide additional strength and some protection against puncturing or tearing.
  • a double-layer package like the pouch/bag combination is easy and safe to use.
  • the Operator simply takes the combination out of the shipping carton, tears open the protective bag, and without opening - or even touching - the inner pouch simply tips it into an appropriate quantity of water, whereupon the water- soluble primary packaging material dissolves and the contents of the pouch disperse as required.
  • the Operator is not exposed to the pouch's possibly hazardous contents, and the risk of accidental spillage is reduced.
  • Typical flexible water-soluble packaging materials useful as the primary packaging - the pouch - are the various films made from polyvinyl alcohol (PVOH), while typical protective materials useful as the secondary packaging - the bag - are nylon/polyethylene laminates. Many other possible materials are described in the aforementioned US and European Patent Specifications.
  • PVOH (and other) films can if properly used make excellent water-soluble pouches for all sorts of fluids.
  • the pouches can become susceptible to damage due to mechanical shock, despite their enclosing protective bag. It is too easy for a severe impact to take the water-soluble pouch material beyond its elastic limit, causing rupture typically around the seal area of the pouch.
  • such materials have flexibility and like characteristics which are, regrettably, deleteriously affected by temperature changes. Thus, at temperatures of around 0°C and below PVOH and similar films become increasingly brittle, to the point at which they can fail. The problem will be better understood from the following comments .
  • a PVOH primary packaging pouch containing a liquid or gel, whether in its protective secondary packaging bag or not, is somewhat shapeless, and left to itself will "flow" into the lowest mechanical energy shape it can. On a flat surface this is usually lying flat on the surface; if restrained within a larger container such as a shipping carton it may slump over, creasing as it goes.
  • the present invention seeks a solution to this, so as to reduce significantly the risks associated with stress cracking of the water soluble film used to make the primary packaging pouch.
  • the present invention proposes a way of mitigating, in part if not in whole, the issue of cold temperature transportation of water-soluble pouch packaging - especially that containing hazardous chemicals such as pesticides and herbicides, in both liquid and gel presentations.
  • hazardous chemicals such as pesticides and herbicides
  • the invention was conceived with the transport of hazardous chemicals in mind, other products susceptible to shock could equally utilise its principles. What the invention proposes is a containerisation system which allows for protection of the product against mechanical shock, puncture and cold climate temperature fluctuations. It also puts forward a stand-alone containerisation system which allows for protection of the product.
  • the invention suggests the use of a novel construction of outer, storage-box, container, or holder, in which may be placed the pouch/bag combination, and that will provide the thus- placed pouch/bag combination with the required ability to withstand and be cushioned against the likely physical shocks associated with normal conditions of transport, storage and use.
  • the invention suggests the use, as this holder, of an open- ended sleeve-like receptacle made from a suitably-shaped and -cut blank that has been folded in such a way as to wrap around, and more securely to hold, a pouch/bag combination placed therein; this is accomplished by making the holder in a curvilinear shape like that of a pillow, which shape corresponds more or less to the natural "relaxed" shape of the pouch/bag combination to be disposed therewith.
  • Such a pillow-shaped holder can be achieved by the use of a blank (from which the holder is to be constructed by folding and the like) wherein the fold lines defining the side and end walls of the portion are arcuate, such that as the blank is folded into its erect form it naturally takes on the required pillow shape.
  • the blank is also given edge strips that can be used to provide the holder with cuff-like strengthening and shock-absorbing members around the two end edges of the sleeve, and the holder is kept closed by a closure flap the corners of which are inserted into the space between the cuff members and part of the sleeve body.
  • the invention provides a blank from which may be formed a protective holder, the blank being made of shape-retaining material and comprising a central section having panels defining first and second opposed side walls of the container, with, spaced therebetween by first and second fold lines, an end wall of the container, and a closure flap projecting beyond the second side wall-defining panel and spaced therefrom by another fold line, the first and second fold lines, and said other fold line, all being arcuate, such that the end wall and the closure flap are generally correspondingly elliptical, which blank may be folded into a roughly pillow- shaped holder-forming configuration.
  • the blank also has first and second reinforcing strips extending along the edges of the blank in register with the first and second side wall-defining panels and with the end wall-defining panel, such that the blank may be folded into a holder- forming configuration wherein each reinforcing strip is folded over into contact with the exterior of the first and second side wall-defining panels and of the end wall-defining panel, and at one end of each reinforcing strip the reinforcing strip and the first side wall-defining panel define together a slot to receive a respective corner of the closure flap.
  • the invention provides a protective holder made from a blank of the invention, and thus being a folded blank of shape-retaining material comprising a central section having panels defining first and second opposed side walls of the container, with, spaced therebetween by first and second arcuate fold lines, an end wall-defining panel, and a closure flap projecting beyond the second side wall-defining panel and separated therefrom by another arcuate fold line, which blank may be folded into a roughly pillow- shaped holder-forming configuration.
  • the blank has first and second reinforcing strips extending along the edges of the blank in register with the first and second side wall-defining panels and with the end wall-defining panel, and in its folded configuration (making the holder) each reinforcing strip is folded over into contact with the exterior of the first and second side wall-defining panels and of the end wall-defining panel, and at one end of each reinforcing strip the reinforcing strip and the first side wall-defining panel define together a slot to receive a respective corner of the closure flap.
  • the invention provides a blank for a protective holder, the blank being made of shape-retaining material.
  • This blank is generally a paper product, preferably corrugated fibre board.
  • other materials including multi-wall materials, may be used - typically plastics sheets such as that known by the trade name "CORREX” .
  • a preferred material is a single-wall "B" flute corrugated fibre board material made from recycled materials, although it will be understood that the fluting media used may vary depending on the nature of the product to be packaged and the strength required in the holder.
  • TEST the material known by the trade name "TEST” is particularly preferable since it is made from recycled material and is therefore inherently weaker than a pure kraft (virgin), construction. This is a desirable feature, as a holder made therefrom, when assembled and subjected to mechanical shocks, affords much greater resilience (cushion factor) and energy- absorbing characteristics.
  • the fluting is preferably aligned generally at right-angles to the first and second fold lines (and thus aligned parallel with the blank edges and any reinforcing strips). This gives increased shock-absorbing and inherent strength properties to the holder made therefrom.
  • the blank has a central section in which there are panels defining first and second opposed side walls of the holder, between which, and defined by first and second fold lines, is an end wall of the holder. It also has a closure flap projecting beyond the second side wall-defining panel and spaced therefrom by another fold line.
  • Each of these fold lines is arcuate, the sense of the arc - bowed in or bowed out - being such that the end wall and the closure flap are generally correspondingly elliptical. It is this which causes the holder erected from the blank to take on the desired pillow shape that more or less matches the natural shape of the liquid-containing bag to be disposed therein.
  • the arcuate nature of the fold lines defining the elliptical end walls is preferably such that the centre point heights of the fold lines are generally in a ratio of centre point height:outer limit of the walls of 100:1 or less, so that the residual inflatability of a bag held therebetween is set at optimum performance to dissipate maximum "hydraulic shock".
  • a preferred range is from 4:1 down to 1.5:1, and in one example the ratio is 2:1. It might also be worth observing that the greater the degree of arc the more the erected holder will be "waisted" as well as "rounded".
  • first and second opposed side walls alongside of which are first and second reinforcing strips. These strips fold over, in the blank's erected form, to provide cuff-like members at the open ends of the thus-produced sleeve-like holder, and these cuffs afford the holder with extra end strength.
  • the blank additionally including third and fourth outer reinforcing strips joined to the first and second reinforcing strips respectively at third and fourth fold lines extending longitudinally of the blank, wherein in the folded configuration of the blank these third and fourth outer reinforcing strips are folded about the third and fourth fold lines into contact with the outwardly facing surface of the first and second reinforcing strips - the combinations of side wall panels, first and second (inner) reinforcing strips and third and fourth (outer) reinforcing strips then having a Z-configuration when the blank is folded to form the holder.
  • the invention's blank has a central section having panels defining first and second opposed side walls spaced by first and second fold lines from an end wall-defining panel. Most preferably the blank also includes a second end wall-defining panel opposite the first one. This second end-wall panel may be thought of as that part of the closure flap-defining panel inboard of the free edge thereof, and thus as being positioned between the second side wall-defining panel and the closure flap-defining panel and joined thereto either side thereof by respective sixth and seventh fold lines.
  • the fold line between the second end wall-defining panel and the adjacent second side wall-defining panel is, of course, the "other" fold line referred to hereinbefore, and is arcuate.
  • the seventh fold line, between the second end wall-de ining panel and the closure-flap- proper part of the closure-flap defining panel is also arcuate in shape, so that both end wall-defining panels are substantially elliptical (and the blank folds to make a holder with the required pillow shape).
  • the holder of the invention - that is, the holder made from the blank of the invention - is, as explained previously, primarily intended to be an outer, protective holder for a bag - specifically, a pouch/bag combination - of some liquid or gel substance.
  • the invention therefore naturally extends to the conglomerate of a holder of the invention when including interposed between the first and second side walls a bag - specifically, a pouch/bag - containing such a liquid or gel.
  • This bag may conveniently have at one end a longitudinally-extending flap defining a handle which projects outwardly of the erected holder when the bag is disposed therein.
  • the bag advantageously has a shape matching that of the outer holder - thus, a waisted shape which is congruent to the preferred waisted shape of the second side wall-defining panel (such a shape is normally natural to a bag made from what is in effect a pair of flexible oblong sheets joined face to face all round their periphery and containing a liquid or gel).
  • a number of pouch/bag-filled blank-derived holders of the invention can be quite conveniently stacked side to side in a relatively stable and safe manner, without significant risk of the pouches rupturing.
  • the adjacent conglomerates lie major face to major face but the contact between them is not full face but rather along a line where each curved pillow surface touches the next. This allows the stack to absorb applied mechanical shock energy both by the individual conglomerates rocking back and forth, and by them flattening out and distorting slightly.
  • these cuffs act both to stabilise the conglomerates against too much rocking and also, the cuffs being themselves resilient and spring-like, to absorb even more of any applied energy.
  • a stack of this kind can then be contained within a larger, conventional shipping carton (made from corrugated fibreboard, say), again for storage or transport, with a reduced or even zero risk of any of the individual component's contents being damaged if the larger carton is dropped.
  • a number of conglomerates of pouches, bags and holders of the invention, both in and out of larger shipping cartons (these latter held eight filled holders), were tested for Drop Strength according to the standard UN Drop Tests ( see Martin Castle ' s The Tr.ansport of Dangerous Goods, Revised Addition published by PIRA International in 1995).
  • the filled cartons were dropped from various heights (up to about 1.2m, at which height the UN Drop Tests are effected) at various temperatures (down to -23°C) and in several orientations (flat on, edge on, corner on, etc) onto a hard surface. There were no failures.
  • the invention provides, in its preferred form, a blank from which may be formed a protective holder, the blank being made of shape-retaining material and comprising a central section having panels defining first and second opposed side walls of the holder, with, spaced therebetween by arcuate first and second fold lines, an end wall of the holder, a closure flap projecting beyond the second side wall-defining panel and spaced therefrom by another arcuate fold line, and first and second reinforcing strips extending along the edges of the blank in register with the first and second side wall-defining panels and with the end wall-defining panel, which blank may be folded into a pillow-shaped holder-forming configura ion wherein each reinforcing strip is folded over into contact with the exterior of the first and second side wall-defining panels and of the end wall-defining panel, and at one end of each reinforcing strip the reinforcing strip and the first side wall-defining panel define together a slot to receive a respective corner of the closure flap.
  • the invention also provides, in its preferred form, a protective holder made from a blank as just defined.
  • a protective holder made from a blank as just defined.
  • Such a holder affords multi-directional energy-absorbing impact properties, particularly at temperatures below zero.
  • Figure 1 shows a blank according to the present invention and capable of being used to form a single "wrap-around" outer “storage-box” container, or holder, unit of the invention
  • Figure 2 shows a perspective view of the blank, partially folded (nearly into the form of a "wrap-around" holder unit of the invention), before insertion of the water-soluble primary pouch/water- protective bag combination, and before final erection;
  • Figure 3 shows the fully-formed and erected holder unit according to the invention in its locked-together configuration
  • Figure 4 shows how the assembled "wrap-around" holder units stack one on top of the other
  • Figure 5 shows an overhead view of the package in laid flat configuration, and shows the integral handle flap of the water- protective bag.
  • the "wrap-around" holder unit, or outer part, shown in Figures 2 (partially folded) and 3 (fully folded) may be formed from the single blank (generally 1) shown in Figure 1.
  • the blank 1 comprises a central substantially-rectangular portion comprising a first side wall region (2) separated from a second side wall region (4) by a generally elliptical first end region (6) bounded by respective substantially elliptical fold lines (8,10).
  • the end of the second side wall region 4 remote from the first end region 6 lies contiguous to a further elliptical end portion (12) defined by respective curved fold lines (14,16).
  • a closure flap (18) having, at its opposite ends, respective locking tabs (20) of right-angled triangular form with the hypotenuse of the triangle defined by a respective fold line (22).
  • Lying along the lateral margins of the central region 2,6,4,12 of the blank 1 are inner margin strips (24) and outer margin strips (26) such that the inner margin strips 24 are joined to the central region 2,6,4 of the blank by respective fold lines (28) and are joined to the respective outer margin strips 26 by further fold lines (30).
  • the fold lines 28,30 may conveniently be perforated, to provide improved shock-absorbing properties and to allow the blank to be more easily assembled.
  • each end of the arcuate fold lines 8,10 defining the elliptical first end region 6 are further fold lines (9 and 11 respectively), defining external reinforcement regions (32) of truncated rhombic form.
  • any board stock used for the blank is preferably aligned from left to right as viewed in Figure 1, i.e. longitudinally of the central panel region 2,6,4,12,18, and parallel to the fold lines 28,30. As noted, this gives increased shock- absorbing and inherent strength properties to the holder unit.
  • the blank 1 of Figure 1 is erected to form the holder shown in Figure 3 by the following operations :-
  • the outer lateral strips may first be folded about the fold lines 30 and the inner lateral strips 24 then folded about the fold line 28, or the inner lateral strips may first be folded about the fold line 28 and the outer lateral strips 26 then be folded about the fold lines 30, or this Z-fold may be made in one operation.
  • the secondary unit is to enclose a primary package in the form of a flat pouch/bag containing a liquid or a gel, that pouch/bag is inserted between the side panels 2 and 4 in Figure 2.
  • the package is then completed by closing the holder unit, which involves firstly bending the triangular locking tabs 20 about their hypotenuse fold lines 22 in order to reduce the spacing between the right angled corners of the two tabs, and then introducing these right angled corners between the respective inner marginal strip 24 and the side panel portion 2.
  • the rigidity of the cardboard material, and the geometric lock formed by the truncated rhombic region 32, will ensure that the two locking tabs 20 will be frictionally held in place between the inner lateral strips 24 and the side panel 2.
  • the outer holder unit of the complete package is shown in Figure 3, and is generally in the form of an elliptical prism.
  • a generally flat primary pouch/bag containing a liquid product (see Fig. 5) can readily be enclosed within this holder unit, and is then totally enclosed therewithin in such a way that it is protected from the effects of external shock.
  • Figure 4 shows the arrangement when two of the thus closed holder units (i.e. each as shown as in Figure 3) are stacked one on top of the other. They provide a stable stack of the individual reinforced and shock- proof packages comprising the holder unit of Figure 3 and the enclosed primary pouch/bag and liquid or gel product.
  • the primary container bag may have an extension handle portion (34) (see Figure 5) which projects laterally from the closed secondary, i.e. out through either the left-hand side or the right-hand side as viewed in Figure 3. This enables the package to be carried. Alternatively, it would be possible to carry the package by slipping the fingers under the closure flap 18 of Figure 3, relying on the locking effect due to the inherent rigidity of the blank 1 to keep the pack closed and able to bear the weight of the product by holding in this way.
  • a feature of the invention is that the flexible pouch/bag is securely restrained within the holder unit in what is for the pouch/bag essentially a laid-flat position. Accordingly, no matter how the holder is handled or laid down, "wrinkling" of the inner water soluble primary packaging pouch is virtually eliminated.
  • Another feature of the invention is that, with the pouch/bag restrained in the manner described, the arrangement allows the residual inflatability of the primary pouch/bag optimum freedom to dissipate an impulse shock over a longer time. As explained below, this is advantageous. In contrast, were the primary bag to be unrestrained, the liquid or gel would find its own level and the remaining air space of the pouch would relax into a non-planar format, which might cause a fold and thus a potential weakness were shock to be applied to such a configuration.
  • the primary bag When the primary bag is in the flat, restrained position and carried by the handle 34 the bag cannot be accidentally pulled out of the holder unit. This is due to the fact that, in finding its own level, the liquid within the pouch/bag combination compresses the bag material against the side wall construction of the "wrap-around" holder unit, the friction therebetween making a natural constraint.
  • the holder is inverted (bag handle down), and, by grasping the handle, the bag is pulled out for use against the friction; the inversion process, aided by the weight of the liquid or gel travelling to the bottom end of the bag 33, makes complete or partial removal of the bag a controlled procedure.
  • the invention can provide a stand-alone pack where the "wrap-around" holder units do not need a specific design of external protection - that is, a number of them do not need to be stored within some larger box such as a shipping carton (although that is, of course, quite possible).
  • some larger box such as a shipping carton (although that is, of course, quite possible).
  • the energy-absorbing crumple zones formed by the reinforcing strips allow the pack, even when filled with a 1 litre bag of product, to be dropped from as much as 1.2m and yet withstand the impact at any angle or face.
  • This is made possible by the unique design of the pack in erection of the blank and by the way the primary bag is supported therewithin.
  • the bag is supported both by clamping at both ends and by the locking tabs 20.
  • the end panels which have a reverse tuck 32 at each end when folded over, are under tension, and act as a buffer zone to absorb shock. They also act as a stacking medium that takes the stacking weight away
  • the curved end walls are such that the centre point heights of the fold lines 8,10,14,16 are in a 2:1 ratio of centre point height'.outer limit of the walls.
  • the shape of the side walls so far described means that only the reinforced buffer "end” fittings 32 will be subjected to most of the energy in any impact imparted.
  • the end crumple zones are therefore designed not only to provide stacking strength but also to provide localised shock protection.
  • the elliptical design of the side panels with the fluting running in the longitudinal (vertical) direction allows for considerable stacking strength.
  • flaps are protruding, and in the event of the holder being subjected to a "base drop" are the first impact zone of the holder. This is advantageous, because the lengthways fluting is considerably weaker than vertical fluting, and will collapse rapidly on impact, thus acting as a sacrificial buffer before coming to rest on the two inner foldover sections, which afford considerably more strength.

Abstract

Il est conseillé depuis quelques années d'emballer des produits chimiques, tels que les herbicides et les pesticides, dans une poche souple en matériau hydrosoluble tel que le PVAL. La poche est placée à l'intérieur d'un sac souple résistant à l'eau et le sac est muni d'une anse externe, habituellement confectionnée en carton ondulé ou avec un matériau similaire pour donner au sac une plus grande résistance et le protéger des conditions ambiantes possibles. Cet assemblage en trois couches est d'utilisation facile et sûre, mais présente quelques inconvénients, en ceci que l'anse externe ne semble pas tenir convenablement le sac et risque trop facilement d'être endommagée par un choc mécanique, si la poche placée à l'intérieur du sac devient cassant. La présente invention propose, pour résoudre le problème, une solution consistant à équiper l'ensemble poche/sac d'un nouveau type d'anse externe qui assure une protection considérablement améliorée contre les chocs. Plus spécifiquement, l'invention concerne l'utilisation, comme partie externe de l'ensemble en trois couches, d'une anse de type manchon à extrémité ouverte, en forme de coussin, confectionné avec une ébauche (1) convenablement découpée et façonnée, pliée de façon à prendre solidement le sac. La solution de l'invention consiste aussi, de préférence, à munir l'anse d'éléments de renforcement et d'amortissement en forme de poignets (24, 26) autour des deux bords terminaux du manchon. Le manchon est maintenu fermé par un volet de fermeture (18) dont les angles (20) sont avantageusement insérés dans l'espace entre les éléments en forme de poignets (24, 26) et une partie du corps du manchon (4).
