Definitions

  • the present invention relates to packaging of goods, in particular consumer goods such as food, drink, toiletries, etc.
  • Known packaging systems use a box or a tray made of cardboard (corrugate), a plastic film, or a combination thereof. If combined, the box or tray usually supports the goods, while the plastic film is provided around the box or tray containing the goods.
  • One known technique uses a heat shrink film, which is provided around goods and a tray and then treated in a heat tunnel.
  • the heat shrink film shrinks and tightens around the goods and the tray.
  • the use of a heat tunnel is expensive, especially in terms of energy consumption.
  • certain types of goods such as aerosols stored in pressurized containers
  • food safety limitations e.g. food safety risk of chilled or frozen foods passing through the heat tunnel
  • Quality limitations e.g. heat spoilage of foods or packaging.
  • An alternative approach is to pack goods inside a box.
  • Such boxes are usually made of cardboard.
  • the cardboard of the boxes has to be sufficiently thick.
  • the boxes usually have full walls, with no openings in order to protect the goods from damage and to protect them from falling out of the box.
  • the boxes are glued and/or taped together to prevent them from disassembling or falling apart. Such packaging may consume a great deal of cardboard.
  • Unpacking such a conventional box usually requires the box to be opened by hand, which usually involves cutting the tape which holds the box shut. Then, the goods have to be taken out of the box and placed in freezer one by one. This makes the opening and unpacking process inefficient, especially in a case where many small items are to be placed in the freezer, because it takes a great deal of worker's time. This is disadvantageous, because apart from the time a worker needs to put the items into the freezer, it also increases the time the freezer has to be opened and the time the frozen goods are exposed to a temperature above zero, thus contributing to higher energy consumption and/or risk of spoiling the foods.
  • trays are wrapped in heat shrink plastic film. Unpacking of a conventional tray covered in heat shrink plastic film is also time consuming and inefficient. A further drawback is the need to cut the film using a knife or a similar sharp instrument. This is dangerous from the health and safety point of view.
  • a packaging system for goods and a packaging method are provided.
  • the packaging system according to a first aspect comprises a box for holding the goods, the box having four side walls, a front face and a rear face; wherein the front face comprises a wall provided with front flaps defining a front window; wherein the packaging system further comprises either
  • front flaps provided in the front face are configured to disengage and thus allow the goods to be unloaded from the box after either the plastic film or the at least one band has been removed and the box has been turned so that the front face faces downwards.
  • a packaging system for goods comprising a box for holding the goods, the box having four side walls, a front face and a rear face; wherein the front face comprises a wall provided with front flaps defining a front window; wherein the packaging system further comprises either
  • front face of the box is rectangular, the front face comprising a pair of shorter front flaps and a pair of longer front flaps, the shorter front flaps being positioned over the longer front flaps.
  • the packaging system according to the first aspect or the second aspect may use one or more of the following features:
  • the front flaps may be configured to disengage under the weight of the goods; - the front flaps may be configured to disengage when two of the front flaps are pulled apart;
  • the front face of the box may be rectangular, the front face comprising a pair of shorter front flaps and a pair of longer front flaps, the shorter front flaps and the longer front flaps comprising interlock features configured to engage and thus form the front face when the shorter front flaps are positioned over the longer front flaps, the interlock features being configured to disengage when the force acting upon the front flaps is less than 30 N;
  • the front flaps may be configured to disengage in a single action
  • the interlocking features may be configured to disengage simultaneously;
  • the interlocking features may be configured to prevent ripping or tearing of the front flaps or the interlock features while the interlock features are disengaged;
  • the interlock features provided on the longer front flaps may comprise outer tab parts, apertures, and an inner tab part;
  • the interlock features provided on the shorter front flaps may comprise base parts and a tab; and the tabs provided on the shorter front flaps may be configured to pass into the apertures provided on the longer front flaps so that adjacent the corners of the box, the inner tab parts overlap the tabs, while the base part overlaps the outer tab parts;
  • the apertures may comprise curved bottom parts, and a portion of the aperture close to the bottom part may be narrower than the portion further from the bottom part;
  • the apertures may be less than 6 mm deep;
  • the base part may comprise corner portions, and the corner portions may be curved;
  • the overlap of the interlock features may be less than 6 mm;
  • the overlap of the interlock features may be in the range of 2 mm to 5 mm;
  • the front flaps provided in the front face may be configured to disengage if the goods weigh more than 0.1 kg;
  • the front flaps may be 4 to 6 cm high;
  • the front flaps may be 5 cm high;
  • a packaging method uses a box and either a plastic film, or at least one band, the box having four side walls, a front face and a rear face, wherein the front face comprises a wall provided with front flaps defining a front window; the method comprising: positioning the goods in the box through the front face; positioning shorter flaps of the front face over longer flaps of the front face; and either
  • the method according to the third aspect may further comprise, when positioning the shorter flaps over the longer flaps, engaging interlock features provided on the front flaps of the box.
  • a method of unpacking goods provides for unpacking goods from a package formed of a box and either a plastic film or at least one band, wherein the goods are positioned inside the box, the box having four side walls, a front face comprising front flaps defining a front window, and a rear face, the front window in the front face being configured to disengage and thus allow the goods to be unloaded from the box when the box turned so that the front face faces downwards, wherein either (i) the plastic film is wrapped around the box, and the plastic film comprises perforations along one of the side walls, the front face or the rear face, or (ii) the at least one band is placed around the box; the method comprising: locating the perforations and breaking the film by pulling the film apart along the perforations and removing the film from the box, or cutting the band; turning the box so that the front face faces downwards; unloading the goods.
  • the packaging method according to the fourth aspect may use one or more of the following features:
  • the front flaps may disengage under the weight of the goods and/or when two of the front flaps are pulled apart;
  • the front flaps provided in the front face may disengage if the goods weigh more than 0.1 kg;
  • the front face of the box may be rectangular, the front face comprising a pair of shorter front flaps and a pair of longer front flaps, the shorter front flaps being positioned over the longer front flaps such that opening the longer front flaps pushes the shorter front flaps open;
  • the shorter front flaps and the longer front flaps may comprise interlock features configured to engage and thus form the front face when the shorter front flaps are positioned over the longer front flaps, wherein the interlock features may disengage when the box is turned so that the front face faces downwards and the force acting upon the front flaps is less than 30 N.

  • Figure 2 is a foldable blank which may be used to make the box of Figure 1 ;
  • Fig 3 is a box wrapped in a plastic film according to an embodiment of the present invention.
  • Figs 4a, 4b and 4c are flow charts illustrating methods of packing and unpacking the goods.
  • Figs 5a-c illustrate the unpacking of the goods.
  • FIGS 1 -5 depict one embodiment of a packaging system according to the present invention.
  • the packaging system according to this embodiment comprises two parts: a box 1 and a plastic film 6.
  • the box 1 is preferably made of cardboard.
  • the box 1 may be made of kraft paper, suitable plastic material, polystyrene, wood, carton board, folding box board, or any suitable case material (case material being the collective term for all layers making up a corrugated box).
  • suitable plastic material polystyrene, wood, carton board, folding box board, or any suitable case material (case material being the collective term for all layers making up a corrugated box).
  • case material being the collective term for all layers making up a corrugated box.
  • use of cardboard is preferred because of its low cost and good mechanical properties.
  • the box 1 has side walls 1 1 a-d, a front face 12 and a rear face 16.
  • the front face 12 of the box 1 has a front window 13.
  • the front window 13 may take any suitable shape, e.g. according to the shape of the box 1 (as explained below).
  • the front window 13 is at the centre of the front face 12, but the front window 13 may be provided at a non-central location.
  • the rear face 16 of the box 1 may have a rear window 15.
  • the rear window 15 may be rectangular, or may take any other suitable shape, e.g. according to the shape of the box 1.
  • the rear window 15 may be positioned at the centre of the rear face 16, or may be provided at a non-central location. In some embodiments, the rear window 15 is not provided, and the rear face 16 is fully closed.
  • the rear window 15 may be smaller and/or narrower than the front window 13. Such arrangement with the front window 13 longer and/or wider than the rear window 15 is beneficial because it facilitates easy removal of the goods out of the box 1 (as described below).
  • the rear window 15 and the front window 13 provide strength to the box 1 and enhance its capability to hold and transport goods. It may also improve stability of the boxes 1 when a box is positioned on top of another box.
  • the boxes 1 are preferably oriented with the rear face 16 downwards during transport and handling. In such case, rear flaps 15a-d provided on the rear face 16 of the top box engage front flaps 13a-d provided on the front face 12 of the bottom box, and the boxes may be more stable. In case the boxes are not oriented with the rear face 16 downwards, the front and rear flaps 13a- d, 15a-d can prevent the adjacent side wall of the box from deforming (bending) inwardly, and therefore may reinforce the box.
  • the four side walls 1 1 a-d are rectangular, with two opposing side walls 1 1 a, 1 1c being longer, and the other two opposing side walls 1 1 b, 1 1 d being shorter.
  • the side walls may be of any other shape and configuration, e.g. square.
  • the side walls may be more or less than four, e.g. three or five. Therefore, any desired shape of the box (for example triangular box, hexagonal box etc.) may be obtained.
  • the box 1 may be formed by folding a foldable blank 10 along the lines shown in Fig 2.
  • a tab 14a at one end of the blank 10 is glued or otherwise attached to the edge 14b of the sidewall 1 1 c at the opposite end of the blank to form a partly assembled box 1 .
  • the box 1 can be stored in a partly assembled but still flat state, without engaging front flaps 13a-d (described below) and without fully forming the box.
  • the box 1 can be formed into its fully assembled state immediately before use.
  • the side walls 1 1 1 a-d are provided with front flaps 13a-d and with rear flaps 15a-d.
  • the rear flaps 15a-d are positioned opposite to the front flaps 13a-d.
  • the front flaps 13a-d comprise a pair of longer front flaps 13a, 13c, corresponding to the longer side walls 1 1 a, 1 1 c, and a pair of shorter front flaps 13b, 13d, corresponding to the shorter side walls 1 1 b, 1 1 d.
  • the front flaps 13a-d may comprise interlock features, or, alternatively, they can be unsecured. If the interlock features are not provided, the flaps 13a-d are held closed during the transport and handling by the plastic film (as described below).
  • the shorter front flaps 13b, 13d are preferably positioned over the longer front flaps 13a, 13c, i.e. the shorter front flaps 13b, 13d overlap the longer front flaps 13a, 13c when seen from the outside.
  • the front flaps 13a-d even if unsecured, still provide reinforcement for the side walls 1 1 a- d during handling, stacking and transporting, as described above.
  • the shorter front flaps 13b, 13d can be pushed open by the longer front flaps 13a, 13c when goods are to be unloaded from the box.
  • the interlock features are designed to be easily opened. To achieve this effect, the interlock features are designed so that they do not engage permanently.
  • front flaps 13a-d may be narrow, e.g. between 4 to 6 cm high, preferably 4.5 cm to 5.5 cm high, as further detailed below.
  • each of the longer front flaps 13a, 13c comprises a pair of apertures 134 (described below).
  • the apertures 134 are positioned approximately 4 cm from the shorter outer edge of the respective longer front flap 13a, 13c.
  • the apertures 134 are provided in a form of inwardly tapering cutouts.
  • the apertures may be generally parallel with respect to the shorter outer edge of the respective longer front flap 13a, 13c.
  • the apertures 134 divide the longer front flaps 13a, 13c into a pair of outer tab parts 132, positioned adjacent to the outer edges of the front flaps 13a-d, and a single inner tab part 136, positioned between the apertures 134.
  • the outer tab parts 132, the apertures 134, and the inner tab part 136 together form interlock features provided on the longer front flaps 13a, c. These interlock features cooperate with the interlock features provided on the shorter flaps 13b, d (described below).
  • the above value 4 cm is merely an example. In general, the distance between the apertures 134 and the shorter outer edges of the longer front flaps 13a, 13c will depend upon the height of the front flaps 13a-d (the apertures 134 are positioned such that they receive the shorter front flaps 131 ).
  • Each of the shorter front flaps 13b, 13d comprises a base part 131 and a tab 133.
  • the tab 133 is narrower than the base part 131 , and protrudes outwardly from the base part 131.
  • the base part 131 comprises two corner portions 131 a.
  • the tab 133 may be positioned centrally on the base part 131 .
  • the base 131 and the tab 133 together form interlock features provided on the shorter front flaps 13b, d.
  • the interlock features 131 -136 cooperate to form the front face 12 from the flaps 13a-d. Longer front flaps 13a, c are folded. The shorter front flaps 13b, d are then folded over the longer front flaps 13a, c.
  • the corner portions 133a of the tabs 133 pass into the apertures 134 so that adjacent the corners of the box, the inner tab parts 136 overlap the corner portions 133a, while the base part 131 overlaps the outer tab parts 132.
  • the front face 12 with the front window 13 is assembled.
  • the aperture 134 which is positioned between the outer tab part 132 and an inner tab part 136, is preferably not deeper than 6 mm.
  • the minimum depth of the aperture 134 may be 3 mm.
  • the aperture may be between 4 mm and 5 mm deep.
  • the aperture 134 is 5 mm deep.
  • the aperture 134 is preferably tapered, with a bottom part 134a of the aperture 134 curved.
  • the bottom part 134a of the aperture 134 is U-shaped, and a portion of the aperture 134 close to the bottom part 134a narrower than the portion further from the bottom part 134a.
  • the bottom part 134a is preferably a continuous, smooth curve.
  • the corner portion 131 a of the base part 131 is preferably also curved, i.e. the corner portion 131 a is not provided with a sharp corner.
  • the corner portion 131 a is preferably a continuous smooth curve.
  • the overlap of the shorter front flaps 13b, d over the longer front flaps 13a, c may be less than 6 mm.
  • the overlap is in the range of 2-5 mm, more preferably 2-3 mm.
  • Such interlock features 131 -136 provide a limited amount of friction, and therefore the interlock features 131 -136 open once a relatively small force acts upon them.
  • the force necessary to open the interlock features 131 -136 may be less than 30 N.
  • the force necessary to open the interlock features 131 -136 may for example be around 20 N.
  • the interlock features 131 , 134 may be too rigid to open, or too rigid to open simultaneously as desired (as described below). In other words, the force necessary to open the interlock features 131 -136 may be higher than e.g. 30 N. Further, the interlock features 131 -136 may be too rigid in the sense that the interlock features 131 -136 or the flaps 13a-d may rip or tear during the process of being pushed open and thus disengaging.
  • interlock features 131 -136 or the flaps 13a-d negatively influences the process of disengaging the interlock features 131 -136, because if some of the interlock features 131 -136 tear or rip, these interlock features are slower to disengage. Thus, they do not open together with the rest of the interlock features. This negatively influences the way the goods are unpacked (as described below). Some or all of the interlock features 131 -136 may sometimes disengage during packing, transport and handling. Disengaging of an interlock feature 131 -136 may for example occur due to forces exerted on the box 1 when goods are being put into the box, due to forces exerted when wrapping the box with film, or due to forces exerted during subsequent handling of the box.
  • the integrity of the box 1 is maintained due to tension of the film wrapped around the box.
  • the shorter front flaps 13b, 13d are folded over the longer front flaps 13a, 13c. That is, when the box is viewed from outside, the shorter front flaps 13b, 13d are outside of the longer front flaps 13a, 13c. If both of the interlock features 131 -136 at one end of the box disengage, then the disengaged shorter front flap 13b, 13d remains folded over the longer front flaps 13a, 13c. Initially the shorter front flap 13b, 13d is held in place by the film.
  • the shorter front flap 13b, 13d remains in place and continues to retain goods in the box 1 even if it has become disengaged.
  • the shorter front flap 13b, 13d remains in place until it is pushed open by opening movement of the longer front flaps 13a, 13c.
  • the longer front flaps 13a, 13c are moved to the open configuration they push open the shorter front flaps 13b, 13d.

  • Providing the interlock features is preferable, because once engaged, they reinforce the box 1 , help to keep the rectangular shape of the box 1 , and together with the plastic film 6 (described below) help to prevent the goods from falling out of the box 1 .

  • the rear flaps 15a-d are held together by the overlapping portions of the interlock features, which would require significant deformation of the box 1 to disengage. During handling and transport, such deformation of the box 1 is prevented by the plastic film 6 (described below).
  • flaps 13a-d are not provided with the interlock features, and are left unsecured, may be particularly beneficial for boxes containing goods weighing less than 1 kg, more particularly less than 0.5 kg. However, this embodiment may be also used with boxes containing heavier goods (e.g. more than 1 kg or more than 5 kg).
  • the box 1 avoiding use of glue to hold the front flaps 13a-d and the rear flaps 15a-d together allows the box 1 to be disassembled and disposed of in a quicker, more efficient manner.
  • the rear flaps 15a-d are glued or taped together instead of, or in addition to, using interlock features as described above.
  • front flaps 13a-d use of glue to hold the front flaps 13a-d together is avoided. This allows the goods to be unpacked in an easier, more efficient manner.
  • the front flaps 13a-d are designed to open under specific circumstances, as described below, and if no glue is used, opening of the front flaps 13a-d is easier to achieve.
  • the front face 12 has a front window 13.
  • the rear face 16 may have a rear window 15.
  • this is achieved by providing the front flaps 13a-d and the rear flaps 15a-d in a form which is not high enough to form a full wall when the box is assembled.
  • the height of the front flaps 13a-d may be between 4 cm and 6 cm.
  • the height of the flaps 13a-d is between 4.5 cm and 5.5 cm, or between 4.8 cm and 5.3 cm.
  • the height of the flaps 13a-d may be 5 cm.
  • the height of the rear flaps 15a-d may be at least 8 cm, preferably at least 8.5 cm.
  • the rear flaps may be 8.9 cm high.
  • flap sizes provide enough space for cutting out the interlock features described above, and also provides sufficient support for another box which would be positioned on top of the box 1 in case the boxes are stored or transported positioned on top of each other. It also reinforces the side walls 1 1 a-d adjacent to the front flaps 13a-d and the rear flaps 15a-d, and allows only minimal bending of the side walls 1 1 a-d.
  • flap size is also beneficial during manufacture of the box blank, because it allows a single pass production through a standard case maker. In case of the height of any of the front flaps 13a-d and/or the rear flaps 15a-d being less than 4 cm, the blank would need to be die cut and glued, using two separate processes. Using two separate processes would increase the cost of production.
  • the final steps of unpacking the box 1 comprise turning the box 1 so that its front face 12 faces downwards, and either pulling the longer front flaps 13a, 13c apart, or allowing them to open under the weight of the goods. It is beneficial if the front flaps 13a-d all open in a single action, for the reason explained further below.
  • front flaps 13a-d With their height in the above-given ranges, and in particular close to 50 mm, makes unpacking of the box 1 easier. If the front flaps 13a-d are taller than 6 cm, they may impede the release and drop of the product into the freezer. In particular, if higher than the above given ranges, the corners between the flaps 13a-d may not open simultaneously, thus affecting the way the goods are discharged from the box. On the other hand, if the front flaps 13a-d are narrower than 4 cm, they may not fold down flat on the face front 12, and may stand proud even once wrapped by the plastic film 6.
  • a box is cheaper if the material consumption is reduced.
  • One example of the dimensions of the box 1 may be as follows.
  • the height of the box 1 from its front face 12 to its rear face 16 is 334 mm.
  • the height of the front flaps 13a-d is 50 mm.
  • the height of the rear flaps 15a-d is 89 mm.
  • the length of the side wall 1 1 a is 473 mm.
  • the length of the side wall 1 1c is 468 mm.
  • the length of the side walls 1 1 b and 1 1 d is 183 mm.
  • the length of the front flaps 13a-d as well as the rear flaps 15a-d may be 3mm less than the length of the respective side walls 1 1 a-d to which the front and rear flaps are attached.
  • the width of the tab 14a is 25 mm.
  • the box 1 with these dimensions forms a rectangular cuboid. While the side walls 1 1 a and 1 1 c are not of the same length, the overlap of the side wall 1 1 c with the tab 14a provides sufficient length to form a 473 mm side wall when the box 1 is assembled.
  • the boxes 1 may come in various sizes, depending on the size and weight of the goods stored inside the box 1 .
  • the maximum size of the box 1 may be determined by the size of an average supermarket freezer (e.g. 60 cm from the front face 12 to the rear face 16, and e.g. 50 cm between the side walls 1 1 b, d).
  • the box length corresponds to the length of the customer freezer well.
  • the box width may correspond to the width of the product facing in the customer fixture (this usually varies according to the customer, the number of product widths in the facing, and the individual product unit widths).
  • the box height may correspond to the available depth of the customer freezer well.
  • the packaging further comprises a plastic film 6.
  • the plastic film 6 may be made of pre-stretch film, for example pre-stretch LDPE, and in particular pre-stretch LLDPE.
  • Pre-stretch film is a film which is pre-stretched during manufacture, and can be stretched further by e.g. approx. 15% at the time it is being applied to a load (e.g. the box 1 ). This allows a precise tension to be applied during application of the film, and thus allows controlled retention of the goods within the box 1.
  • the retraction force applied by the pre-stretch film prevents or inhibits movement (deformation) of the box 1 and the goods. In other words, when applied to the box 1 , the film maintains its tension, fastens around the box 1 , and retains the box 1 without deforming it.
  • the thickness of the pre-stretch LDPE film may be between 5 ⁇ m and 9 ⁇ m, preferably around 7 ⁇ m, for example 7 ⁇ m.
  • the pre-stretch LDPE film having thickness between 5 ⁇ m and 9 ⁇ m shows the best properties, in particular in terms of ability to stretch.
  • pre-stretch LDPE film which is thicker than 9 ⁇ m may show greater stretch ability and therefore may not provide enough tension to large, heavy boxes to retain the goods (where heavy boxes may mean e.g. heavier than 30 kg).
  • pre-stretch LDPE film which is thinner than 5 ⁇ may show minimal stretch and reduced strength under tension.
  • Film which is thinner than 5 ⁇ may therefore be suitable only for light boxes (where light boxes may mean e.g. lighter than 100 g). Thus, film with a thickness up to 9 ⁇ may be used and film with a thickness of at least 5 ⁇ may be preferred.
  • the pre-stretch film is quick and easy to apply and remove, cheap, and fully recyclable.
  • the pre-stretch film is about 10 times cheaper than the cardboard (corrugate) of which the box 1 is made (and more than 1 0 times cheaper than other materials that could be used to make the box 1 ). It also provides protection for the box 1 and/or the goods stored in the box, because the film itself is waterproof and therefore prevents water (humidity) or dirt from entering the box 1 and damaging the goods and/or water ingress into the material of the box 1 . This is particularly beneficial if the box 1 is made of cardboard.
  • water ingress into the material of the box 1 is a particular issue with boxes 1 used to transport and store frozen goods, as frozen goods attract environmental moisture more than goods which are only chilled or do not need to be cooled at all.
  • the box 1 is provided with the plastic film as described above, there is no need to coat the material of the box 1 with plastic.
  • Such coating is usually provided on the inside and/or outside of the box in order to prevent water ingress. The coating is not necessary when the plastic film is provided, because the water ingress is slower when the box 1 is protected by the film. This reduces costs of the material needed to make the box 1 .
  • the film may be made of any other suitable plastic material with similar properties.
  • the pre-stretch film may be replaced with one or more bands.
  • the bands may be made e.g. from plastic, or from suitable elastic material such as rubber.
  • the bands may take form of straps or any other suitable retention means.
  • Such retention means may be cheaper than the plastic film, but may not provide the environmental protection and structural integrity of the pre-stretched film as described above.
  • the goods are not enclosed by such retention means and this may allow the goods to be tampered with. Therefore, due to water ingress into the box 1 , the bands are not particularly suitable for use with frozen food. Also, due to the possibility of tampering, the bands are not particularly suitable for food in general or other items which should be held in tamper- proof packaging.
  • the goods are inserted into the box 1 , so that the front (upper) side of the goods faces the rear wall 16 (step S1 a).
  • the front flaps 13a- d are then positioned so that the shorter front flaps 13b, 13d are positioned over the longer front flaps 13a, 13c (step S2a).
  • the interlock features 131 to 136, if provided, are then engaged (step S3a).
  • the plastic film 6 is wrapped around the box 1 (step S4a), as described below.
  • the front flaps 13a-d thus form the front window 13.
  • the procedure would work in a similar way if the goods were loaded through the rear face 16. In such case, the front flaps 13a-d are positioned so that the shorter front flaps 13b, 13d are positioned over the longer front flaps 13a, 13c before the goods are positioned in the box 1 .
  • the back (lower) side of the goods which displays the barcode and/or other identification of the goods, faces the opening 13. This is beneficial during transport and handling of the boxes 1 .
  • the content of the box 1 and the barcodes or other identification can be seen through the front window 13, and the front (upper) side of the goods can be seen through the rear window 15 (if provided). Therefore, there is no need for printing on the box 1 or putting any kind of labels on the box 1 . This simplifies handling of the boxes, avoids labelling mistakes, and saves costs.
  • the plastic film 6 is wrapped around the box 1 (step S4a).
  • the process of wrapping the box 1 in the plastic film 6 may be conventional, e.g. as described in patent applications published under WO9009316, WO2006051281 , WO201 1004157, WO2015025142 or WO2015067940.
  • the box 1 may be wrapped helically with the plastic film 6. As the box 1 is wrapped, more than one layer of the film may cover the wrapped areas of the box 1. With the helically wrapped box, successive layers of the film overlap.
  • the number of layers of the overlapping film in case the box 1 is wrapped helically may depend on the material and/or thickness of the plastic film 6 and on the size and weight of the goods which are stored in the box 1.
  • the number of layers could be determined based on the known properties (such as strength) of the plastic film 6.
  • the film may be for example 250 mm wide, 125 mm wide, or of any other suitable width.
  • a single layer of the pre-stretch film with minimal overlap is sufficient for light to medium weights, i.e. for boxes weighing less than 10 kg. Typically the film overlaps are between 20 - 100 mm, depending on the weight of the box.
  • At any single point on the wrapped box 1 there may be one or two layers of the film. Due to the above-described features of the box, in particular the front flaps 13a-d and the rear flaps 15a-d, two layers of the film are sufficient even for boxes weighing more than 15 kg, for example between 15 kg to 25 kg. This does not exclude providing three layers of the film, e.g. if extra strength is required.
  • boxes weighing between 100 g - 25 kg can be wrapped.
  • 1 -3 layers are sufficient to hold the goods weighing up to approx. 20 kg in the box 1 , even if the box 1 is turned with its front face 12 facing downwards.
  • the weight of the boxes 1 may be limited to e.g. 15 kg or 9 kg.
  • 1 -2 layers of the pre-stretch film are sufficient for such boxes.
  • the film Before the film is wrapped around the box 1 , the film is pre-stretched, i.e. tension is created in the film by stretching it in a longitudinal direction. When the film is wrapped around the box 1 , it un-stretches (shrinks) and tightens around the box 1 .
  • the film may be perforated on at least one side of the box 1 , on the front face 12 or the rear face 16.
  • the perforations 6a are created during packaging process, when the stretched (tensioned) film passes over a fixed perforation wheel (not shown) when the box 1 is being wrapped in the plastic film 6.
  • the perforation wheel may have a shark-tooth design.
  • a heated bar is used to melt and thereby cut the film after the box has been wrapped. Melting which occurs at the end of the film provides a lip which extends across an end of the perforations and inhibits tearing along the perforations (thereby minimising the chances of the perforations tearing spontaneously.
  • the perforations 6a form a preferred line of opening the plastic film 6.
  • the perforations 6a are preferably provided along the whole length of one of the sidewalls 1 1 a-d, or the front face 12, or the rear face 16.
  • the plastic film 6 does not break open prematurely.
  • Minimal effort from a worker is required to tear along the line of perforation in store (the melted lip of film can be torn easily).
  • the perforations 6a simplify the unwrapping process, thus making it quicker and more efficient.
  • the perforations 6a also eliminate the need for any tools such as knives, therefore reducing risk of injury and further reducing costs.
  • the film used for wrapping the box 1 may be e.g. the pre-stretch LDPE film having thickness of 5 ⁇ to 9 ⁇ as described above.
  • Use of such pre-stretch LDPE film is beneficial because such film shows advantageous stretch properties.
  • Pre- stretch LDPE film having thickness of 7 ⁇ is particularly beneficial because of its optimal stretch properties.
  • the pre-stretch LDPE film of the above-described thickness, i.e. 5 ⁇ /7? to 9 ⁇ , and more particularly 7 ⁇ , provides the box 1 with increased structural integrity without the need to use a heat tunnel to make the film shrink.
  • the pre-stretch LDPE film exerts force (pressure) on the edges of the box 1 , thus holding it together and preventing it from collapsing (as described below).
  • LDPE is also advantageous because it is fully recyclable.
  • the force exerted by the film is sufficient to hold the box 1 together during handling and transport.
  • pressure can be applied to a pair of opposite edges or corners of the box 1 during transport and handling due to improper positioning, rough handling, etc. In the absence of the plastic film 6, this pressure would bring the edges or corners of the box 1 closer together, while the other pair of edges or corners would move further apart from each other.
  • the front flaps 13a-d and/or the rear flaps 15a-d, and the interlock features 131 to 136 and/or 151 , 152 could be deformed enough to disengage. In such a case, the box 1 would disassemble.
  • the film strengthens the box 1.
  • the film increases the structural rigidity of the box 1. Therefore, the adjacent walls forming the respective edge or corner are prevented from accidentally moving too far from their normal interlocked position. (Too far means so far that the interlock features 131 to 136 and/or 151 , 152 to disengage.)
  • the interlock features 131 to 136 and/or 151 , 152 therefore do not disengage, and the box 1 does not disassemble. This applies to a box 1 with weight up to 25 kg. Therefore, there is no need to use glue to attach the front flaps 13a-d together to prevent the box 1 from disassembling. In this way, the costs of glue are saved, and the box 1 is easier and quicker to disassemble and dispose of.
  • the LDPE film is fully recyclable, which is beneficial from an environmental point of view.
  • the plastic film 6 also covers the openings of the box 1 , and thus helps to retain the product within the case.
  • the goods stored in the box 1 according to the present invention are more visible (compared to a conventional enclosed box where the product is only identifiable via a label containing text or barcode).
  • the box 1 wrapped in the plastic film 6 allows an easy visual verification of the contents of the box 1 to take place. Picking errors can be reduced regardless of whether the picker has the ability or proximity to read the text. Additionally, the plastic film 6 helps to protect the box 1 and/or the goods from the environment.
  • any equivalent material to the pre-stretch LDPE film may be used, provided it has similar properties to that of the pre-stretch LDPE film of the above-given thickness.
  • the film stretches less than a 5 ⁇ /D thick pre-stretch LDPE film, or more than a 9 ⁇ thick pre-stretch LDPE film, it may be unsuitable for some applications.

If the pre-stretch film (e.g. LDPE film) is used, it may also cover the edges and the corners of the side walls 1 1 b. Parts of the side walls 1 1 b may be covered by untensioned, loose film 6b. Such untensioned portions 6b are preferably less than 5 cm wide. In case the box 1 is as shown in the Figures, i.e. two of the four sides are larger than the other two sides, it is beneficial to cover the box 1 in the plastic film 6 so that at least the larger sides (sides 1 1 a, 1 1 c in Figs 1 a-c) are covered with the plastic film 6.
  • the pre-stretch film e.g. LDPE film

  • the plastic film 6 may be wrapped around the box 1 in two different directions, thus covering all four walls 1 1 a-d, the front face 12 and the rear face 16. Enclosing the whole box 1 with the plastic film 6 provides the box 1 with extra structural integrity, and it provides extra protection of the box 1 against environment, e.g. rain, humidity etc. Enclosing the whole box 1 with plastic film 6 also increases security. With the box 1 completely covered in the plastic film 6, it is easier to detect tampering. However, it also increases the amount of the film used.

  • providing the film 6 is beneficial because it prevents water ingress which weakens the box 1 . Even if the film 6 is provided, the box 1 usually attracts some moisture, especially on its inside, but the amount of the moisture is small.

  • the packaging according to the present invention allows the retailer to take the box 1 completely away from the goods when the goods are put in the freezer. This increases the visual appeal of the goods, in particular in case of chilled and frozen foods, because the box 1 could become soggy or mouldy.
  • the more efficient process of unpacking and disposing of the box means that this process is less expensive. It requires less time of a worker to unpack the goods into the freezer, arrange them in a required way (e.g. attractive for the customers), and dispose of the used box. If frozen goods are carried in the box, saving time also reduces the need for having freezer open for sufficient time to arrange the goods, which saves energy.
  • the box 1 i.e. the box 1 which has a rear face 16 with 8.9 cm high rear flaps 15a-d, and a front face 12 with 5 cm high front flaps 13a-d, is the most cost-effective configuration of the box 1 .
  • Such box, together with the plastic film 6, provides sufficient resilience to hold and protect the goods inserted into the box 1 , while also using minimum possible amount of cardboard.
  • the plastic film is cheaper than cardboard per metre. Therefore, replacing a conventional, fully enclosed cardboard box with a partly open box 1 , reinforced by plastic film 6, is beneficial from a cost perspective.
  • Pre-stretch LDPE film is 100% recyclable.
  • the packaging is light and its volume is small; this saves transportation costs and fuel.
  • shorter front flaps and “longer front flaps” are intended to indicate lengths of respective front flaps in relative terms. They are not intended to imply that particular absolute lengths of flaps are required.

Abstract

La face avant comprend une paroi munie de rabats avant (13a-d) délimitant une fenêtre avant (13). Le système d'emballage comprend en outre soit un film plastique (6) enroulé autour de la boîte, recouvrant la face avant et la face arrière de la boîte et retenant les marchandises à l'intérieur de celle-ci, ou au moins une bande (6) placée autour de la boîte, placée autour de la boîte de manière à encercler la face avant et la face arrière de la boîte et à retenir les marchandises à l'intérieur de celle-ci.
