Definitions

  • the present invention concerns the field of cardboard packaging and, more particularly, a modular cardboard container for goods, said container consisting of a stackable interchangeable hollow tunnel-shaped part from which a drawer may be pulled out.
  • the invention may be applied to containers for holding any type of object compatible with cardboard, to be shown to a potential purchaser, said container then being returned to its place, after removal of the contents consequent upon a purchase, without upsetting the order of the other goods displayed.
  • the invention is particularly applicable to the sale of footwear.
  • the boxes need to be kept piled according to the model or size number. This order will be correctly established before opening hours, but shortly after will be interfered with during sales work. For the sales assistant this creates a difficulty in quickly noting which models have been sold and must therefore be replaced, and involves extra work by continually having to put piles of boxes back into their right order.
  • the cardboard containers at present on the market do not appear to include anything of this kind; for example, those most like it include a box for "packing men's shirts", or else "matchboxes" of a larger size than normal.
  • the first of these types consists of a cardboard box open at the top, its sides bent inwards to form a double wall for greater strength, there being along each edge a flap that, to hold the whole together, extends from the end of one inner wall towards the other thus occupying a complementary.free area.
  • the package is completed by a flexible transparent plastic cover of the same depth as the box.
  • the double wall so formed undoubtedly renders the box sufficiently rigid to make a pile of boxes holding a light-weight article such as a shirt, but would not be strong enough for piles of boxes containing something heavier. Further, the presence of a lid creates the drawback described above and would continue to exist even if the lid were replaced by a hollow casing of the same flexible transparent material.
  • the matchbox comprises two parts: one being a hollow casing, or "tunnel", the other being an open box containing matches that slides in and out of the casing so that matches can be taken from either end.
  • this type of container suitable for the purpose as the cardboard would have to be very strong in order to support a pile of boxes containing heavier articles while, to pull a box out by pressing on one of the two visible faces, would require a space for access to the back of the pile making it impossible to stand it up against a wall for greater stability and for reducing the space occupied.
  • Purpose of the present invention is therefore to solve the above problem by means of a cardboard container, one part of which consists of a hollow casing, or “tunnel”, into which a second box-shaped part slides, said box-shaped part, here called a drawer, having a base joined to perpendicular sides folded over inwards to form an internal wall for greater strength, said drawer also including:
  • the invention also concerns a method for producing a cardboard container possessing the characteristics stated in Claim 1. This method follows the steps for impressing the required creases and making the cuts in the two sheets of cardboard, one sheet for the tunnel and the other for the drawer, for bending them at the creasing points and any other operations needed to complete the container.
  • the longitudinal internal walls are preferably glued to their respective side walls, and the joins between flaps and internal walls stabilise the front structure of the drawer preventing the longitudinal walls from diverging and causing it to open partially.
  • each opening is rounded better to accommodate the fingers, and marked off above by a crease in the cardboard at a retroflexed flap of the same shape as the aperture.
  • two pairs of matching triangular walls are included between the rear wall of the drawer and the internal wall associated to said rear wall, there being one pair on each side wherein, for each pair:
  • the drawer includes a third pair of flaps joined to both sides of the wall at the rear end of the drawer, perpendicular to said wall and in contact with a respective longitudinal wall at a recess whose outline matches that of the flap so forming a join that stabilises the rear structure of the drawer.
  • the handle may simply be a piece of cord the ends of which are fitted into the central holes cut in the wall and firmly fixed, the associated inner wall preventing entry of dust.
  • an orderly pile of boxed goods can be created on the shelves (or even set up on the floor) allowing articles to be removed without altering the order of those remaining in the pile.
  • the front openings enable the drawer to be pulled out leaving its tunnel in place; the fact that tunnels are interchangeable makes it possible to complete boxing with another tunnel, and finally, the handles at the back make it easier to pick up and carry the whole drawer.
  • a cardboard structure 1 is bent to a hollow parallelepiped shape, consisting of five walls 2, 3, 4, 5, 6, perpendicular to each other and joined, two by two, by parallel creases in the cardboard; of these, the wider walls 3 and 5 form two bases, walls 2 and 4 are narrower and used to form side walls, while part 6, the narrowest with an inwardly tapering edge, is a band glued to the inner face of side wall 2 to keep the structure 1 stable.
  • the two bases 3, 5 and the band 6, are slightly longer than the side walls 2 and 4 by two or more thicknesses of cardboard. Access to the inside of structure 1 is made through its opposite open ends which explains why it will henceforth be referred to as a "tunnel".
  • this shows a second cardboard structure 7 bent into a parallelepiped and consisting of a base 8 from which two longer side walls, 9 and 10 stand up perpendicularly on opposite sides, and two shorter walls 11 and 12 on the remaining opposite sides.
  • This structure 7 is open at the top and for this reason will henceforth be referred to as a "drawer".
  • Walls 9, 10. 11 and 12 are joined to the base 8 by creases in the cardboard; walls 11 and 12 are perpendicular to walls 9 and 10 to which they are joined each by its respective connecting structure, 13, 14, of which a full description is given further on..
  • the length of drawer 7 is about equal to that of the tunnel 1, the width of drawer 7 being such that it easily enters the tunnel 1, remaining in contact with walls 2, 4 (and 6) while doing so.
  • Wall 11 of the drawer 7 is slightly longer than the external width of tunnel 1; pressing against the edge of tunnel 1, said wall 11 is prevented from sliding out beyond said tunnel's open end.
  • Approximately in the centre of wall 11 are two apertures, 15 and 16, placed horizontally and serving to pull the drawer 7 out from the tunnel 1; for this reason wall 11 is described as being at the "front".
  • Figure 3 shows the "rear" side of the drawer 7; the presence of a handle 17 on the wall 12 will be noted.
  • handle 17 consists of a cord the ends of which penetrate inside two holes, 18 and 19, in the wall 12, where, on the other side, they fit into rigid tubes to stop them sliding out.
  • Figure 4 shows the drawer 7 partially inside the tunnel 1; it will be seen here that the front wall 11 of drawer 7 extends at the sides for two short lengths, or shoulders, 11a and 11b, beyond the side walls 9 and 10, said lengths 11 a and 11b being greater than, or equal to, the thickness of the cardboard used to make the tunnel 1.
  • the drawer 7 can be pulled out by the two front apertures, 15 and 16, suitably rounded to favour a finger grip.
  • Figure 5 shows the drawer 7 from the rear end when completely inside the tunnel 1. When in this position, the whole can be lifted by the handle 17 without the tunnel 1 sliding downwards due to opposition from shoulders 11 a and 11b of drawer 7 in contact with the edge of tunnel 1.
  • Figure 6 shows a sheet of cardboard, 1CART, cut and creased, laid out flat, providing the basic material for making the tunnel 1.
  • Parallel creases 2a, 3a, 4a, and 5a have been made in the 1CART cardboard, these lying crosswise to the length of the piece and to be used to form the walls of tunnel 1.
  • the pairs of creases 2a-3a and 4a-5a respectively mark off the two bases 3 and 5.
  • the pair of creases 3a-4a mark off the side wall 4.
  • the other side wall 2 is marked off by crease 2a and by a shorter strip of the 1 CART cardboard.
  • the band 6 to be glued is marked off by crease 5a and by the other shorter strip of the 1 CART cardboard.
  • FIG. 7 shows the sheet of 1 CART cardboard bent round the creases referred to above to form the tunnel 1, shown when not completely closed in order to emphasise the band 6 to be glued onto the corresponding strip of the internal wall 2.
  • Figure 8 shows a second sheet of 7CART cardboard, cut and creased and laid out flat to be used for making the drawer 7.
  • the series of creases is somewhat complex as this sheet includes the two connecting structures 13 and 14 ( Figure 2 ) respectively placed at the front and rear ends of the drawer.
  • the structure of cuts and creases of sheet 7CART is symmetrical in relation to a centre line but is less symmetrical along the transversal axis because of the difference between the two connecting structures 13 and 14. Departing longitudinally from left to right a series of bands 45, 44, 42, 11, 8, 12, 20 may be distinguished, placed side by side and marked off by their respective crosswise creases 43, 41, 40, 33, 32, 21.
  • the terminal band 45 lies between the left-hand edge of the cardboard and the crease 43; band 44 lies between creases 43 and 41; band 42 lies between creases 41 and 40; band 11 lies between creases 40 and 33; band 8 lies between creases 33 and 32; band 12 lies between creases 32 and 21, while the terminal band 20 lies between crease 21 and the right-hand edge of the cardboard.
  • the central band 8 is longer than the others and forms the base of the drawer; the lengths of bands 44, 11, 12 and 20 are practically the same; bands 45 and 42 are practically of the same length but are much shorter than band 44. Creases 33 and 32 are longer than creases 43, 41, 40 and 21 which completes the planimetry of the connecting structure 13 and 14.
  • the 7CART sheet also shows the arrangement of longitudinal creasing to define bands of perpendicular creasing with respect to those already mentioned. Specifically, a first crease 35 at one longer side of band 8 marks off this latter from a band 9 adjoining band 8 and, on the opposite side, adjoining a second band 38 by means of a crease 34. Similarly, a second crease 36, at the opposite side of band 8, marks this latter off from a band 10 adjoining a second band 39 by means of a crease 37. Bands 9 and 10 each contain a strip, 9a and 10a, prepared for gluing respectively to creases 35 and 37.
  • the profiles of the two opposing terminal bands 38 and 39 are partially recessed on their opposite free sides.
  • the profile of band 38 (39) presents a short oblique length 38b (39b) that departs from the end of the band and joins a length 38a (39a) perpendicular to the external edge of said band.
  • the profile of band 38 (39) presents a short practically central oblique length 38d (39d) joined by one end to a length 38c (39c) that perpendicularly joins the crease 34 and, at the opposite end, a length 38e (39e) that perpendicularly joins the external ends of the band.
  • connecting part 26 (30) comprised between a crosswise crease 25 (29), on the side of band 9 (10), and a longitudinal crease 24 (28) at the side of band 12.
  • the profile of connecting part 26 (30) is a rectangular pseudo-trapezoid, its upper base and oblique side being slightly inclined inwards and towards the rounded edge, point of departure of a diagonal crease 27 (31).
  • the terminal band 20 presents two rectangular trapezoidal-shaped lateral flaps, 22 and 23, their greater bases being on the respective longitudinal creases 22a and 23a at the sides of band 20, their oblique sides, respectively 22b and 23b, being on the side of crease 21.
  • the width at the .greater base, respectively 22c and 23c, is much narrower than that of the band 20.
  • the rectangular trapezoidal shape matches with that of the corresponding lateral profile of bands 38 and 39.
  • band 52 adjoining band 9 (10), by means of the crease 33, separated from band 11 by a longitudinal cut 51t (50t) that enables it to pivot round said crease 33.
  • band 52 In band 52 (53) is a rectangular window 54 (55) open on the free side parallel to crease 33.
  • the cut 51t (50t) extends beyond the line of crease 35 by at least the thickness of the cardboard, creating extra width 11 b (11a) on band 11 in relation to band 8. Altogether, this extra width is at least twice the thickness of the cardboard.
  • Band 11 presents two curved cuts, 15t and 16t, separated from each other in a crosswise direction, the semicircular end being joined to two short rectilinear parallel lengths respectively by a crease, 15b and 16b, around which the residual cardboard flaps, respectively 15a and 16a, can pivot.
  • the distance between creases 15b (16b) and 40 is at least equal to that between the external continuous edge of band 52 (53) and the side of window 54 (55).
  • the length of said window 54 (55) is greater than that of the apertures 15a (16a).
  • Band 44 presents two lateral flaps, indicated by arrows 48 and 49. These two flaps expend beyond the width of band 44 (ideally comprised between creases 35 and 36) departing from their respective creases 46 and 47 at the sides of said band 44.
  • the width of flap 48 (49) is practically the same as that of terminal band 45, and is about half (or only a very little less) than the width between the straight edges, 39c and 39e (38c and 38e), of band 38 (39).
  • Flap 48 (49) is crossed by an approximately central oblique cut, 48t (49t), so being divided into two adjoining rectangular trapezoidal flaps, 48a and 48b (49a and 49b).
  • the angle of inclination of this cut 48t (49t) is of an absolute value equal to that of the oblique length 39d (38d). Length of the external edge of flap 48b (49b) is about the same as that of length 39e (38e).
  • Figure 9 shows the first operation that consists of turning the two bands 38 and 39 up against bands 9 and 10 respectively and gluing the parts 9a and 10a prepared for this purpose.
  • Figure 10 shows the how the drawer appears after turning lateral walls 9 and 10 inward by 90° around creases 35 and 36, gluing them to their respective inner walls 38 and 39 so providing extra lateral strength.
  • the two connecting parts 26 and 30 are also pulled inward by turning the respective walls to which they are joined.
  • the two windowed bands, 52 and 53 are drawn towards the inside of walls 9 and 10 to which they are joined, and are also turned a further 90° inwards round crease 33 common to both, thereby creating a window of double length on the front of the drawer.
  • band 11 with everything connected to it, begins to turn inwards around crease 33.
  • band 44 together with the narrower band 42, starts to make a further inward turn around crease 40 causing the lateral flaps to become separated from each other.
  • Figure 11 repeats in greater detail what has been said above about the complex way the cardboard has to be bent at the front end of the drawer. From this figure it will be seen that the two windowed bands, 52 and 53, pivot around the short sides of lateral walls 9 and 10. On completing their turn, windows 54 and 55 become one single window facing onto openings 15 and 16 in the front wall 11 due to the crossing movement made by flaps 15a and 16a. Note should be also taken of the configuration produced by the reciprocal positions assumed by flaps 48a and 48b, 49a and 49b.
  • the seat to be occupied by flap 48b is seen foreshortened on the side wall 10, as marked off by lateral edge 39e, 39d and 39c of the inner wall 39, centrally inclined towards the base 8.
  • Figure 11A shows a section view of how the structure in the preceding figure looks when bending has been completed. It will be seen from this Figure that, starting from the incomplete structure with the two windowed bands, 52 and 53, lying sideways to their respective side walls 9 and 10, a strong frontal structure can be obtained by the following sequence of bending operations:
  • the strengthening structure on the front of the drawer seen in figure 11A , comprises:
  • FIG 11A shows a compact structure internally strengthened by the position of the flaps 48a and 49a whose edges press against the windowed walls 53 and 52, which in turn press against the front wall 11.
  • the lower band 45 doubles the thickness of the base of the drawer in that area and, fitting in below the windowed bands 52 and 53, keeps the structure's internal space completely isolated from the inside of the drawer 7, thus preventing dust from entering.
  • the join made by flaps 48b and 49b in the rectangular trapezoidal seats of the inner longitudinal walls 39 and 38 hinders any possibility of the wall 44 turning towards said flaps, which would weaken the structure at the front of the drawer, thus helping to keep the side walls 9 and 10 anchored to the front wall 11.
  • Frontal rigidity is also increased by flaps 16a and 16b when these are fully pressed inwards.
  • Figure 12 gives an illustration of how the cardboard is bent to form the rear of the drawer 7 starting from the ideal configuration in Figure 10 . In actual fact this configuration cannot be realized on account of elasticity of the diagonal creases 27 and 31 that tend to fold up the triangular bands that meet there, as shown by Figure 12 .
  • the rear structure of the drawer 7 can be completed by a continuous turn of the terminal wall 20 towards the inside of the drawer 7 till flaps 22 and 23 are fully fitted into their respective complementary seats on the sides of the inner walls 38 and 39. Application of slight pressure to band 12 assists the manoeuvre.
  • Figure 2 The final configuration of the join may be seen in Figure 2 which is achieved by completing bending work as in Figure 12 , with the rectilinear section 23c (22c) of the flap 23 (22) in contact with the rectilinear edge 39a (38a) of the inner wall 38 (39), and the oblique section 23b (22b) in contact with the oblique edge 39c (38c).
  • Figure 12 also shows two rigid tubes 17a and 17b that keep the ends of the cord 17, serving as a handle, firmly in place.
  • Figure 13 shows three piles of drawers, inside their tunnels, all containing footwear arranged according to the model - MOD1, MOD 2, MOD3 - and, within each pile, according to foot size that increases from the bottom upwards. It will be seen that some sizes are missing having already been sold but the tunnel holding that drawer remains in place thus maintaining the initial order of the pile. One drawer has been partly pulled out to show the contents.
  • the figure illustrates a particularly unfavourable situation due to the presence of an empty space right at the bottom of the pile: in that case the tunnel must sustain the weight of the entire pile without adequate reinforcement, but for this situation the present invention offers a solution: all that is needed is to fit in some drawer of a colour different from the others.
