- the box 1 for packaging a batch of articles corresponding to the preparation of an order comprises according to a first variant of the invention, a corrugated cardboard belt or the like made from four 2,3,4,5 panels, for example rectangular, arranged vertically and joined to each other by their length, the walls 2,4 and 3,5 opposite being normally, although not necessarily, identical in order to form in the space, a rectangular parallelepiped; this belt is provided in its lower part with a bottom 6 secured to any known way to each of the walls 2,3,4,5 to form a receptacle 10 open upwards.
- the receptacle 10 can be obtained from a simple American half-box or an American box without the upper flaps or even from a tray with a bottom glued for example on entablatures; of course the choice of a parallelepipedic box 1 corresponding to the vast majority of uses, is not limiting and one could perfectly conceive of producing receptacles 10 comprising more than four vertical walls to satisfy a particular need in the handling or transport.
- a flat and rigid element 11 is then forcibly inserted into the interior of the receptacle 10 provided with its heat-shrinkable film 7, the two curtains 8, 9 of which have been folded down outside the vertical walls 3, 5 so as to ply against the film 7 on the bottom 6 of the receptacle.
- the element 11 which comes to lock the film 7 at the bottom 6 of the receptacle 10 is correctly dimensioned to be inserted by force between the two vertical walls 3.5 overlapped by the two curtains 8,9, thus providing a real wedging of the film 7 respectively between the edge 12 of the element 11 and the wall 3 and between the edge 13 and the wall 5.
- the planar element 11 must be rigid to provide maximum blocking of the film 7 between the vertical walls 3,5 of the receptacle 10; advantageously this planar element 11 will be cut from corrugated cardboard, preferably, although not necessarily, to the dimensions of the bottom 6 of the receptacle 10 in order to constitute a real double bottom.
- the flat element 11 will be inserted in such a way that the direction of the grooves 14 is perpendicular to the lines of contact with the vertical walls 3, 5 between which said element 11 is force-fitted.
- FIGS. 3 and 4 a second variant of the box in accordance with the invention will now be given, observing that the parts of FIGS. 3 and 4 which are common to the two variants have the same references as in FIGS. 1 and 2.
- the receptacle 1 will advantageously be formed from four side walls 2,3,4,5, preferably of rectangular shape held together to form a belt, for example of corrugated cardboard or the like secured to a bottom 6, to form in a very usual manner, a receptacle 10 ′ such as an American box without upper flaps or an American half-box or even a tray with single walls or double walls commonly used in the field of packaging.
- a receptacle 10 ′ such as an American box without upper flaps or an American half-box or even a tray with single walls or double walls commonly used in the field of packaging.
- the planar element 11 ′ coming as in the previous variant against the central part of the film 7 on the bottom 6 of the receptacle 10 ′ naturally has all the characteristics of the planar element 11 of the first variant, but it is additionally provided with pins 15,16 extending outwards in the plane of the element 11 'from the opposite edges 12,13 of said element 11' coming into contact with two side walls 3,5 of the receptacle 10 'contributing to the blocking of the two curtains 8.9.
- the two grooves 17, 18 are arranged in the lower part of the vertical walls 3.5 just above the junction line between said walls 3.5 and the bottom 6, over a length at most equal to the length of said walls and normally over a sufficient length to firmly hold the element 11 'against the bottom 6 of the receptacle 10.
- the element 11 'snapped into the grooves 17,18 of the opposite side walls 3,5 not only against the greenhouse by its edges 12,13 the film 7 against the same vertical walls 3,5 but by the play of the two tenons 15 , 16 forms corners which irreversibly embed the base of the curtains 8, 9 in the grooves 17 and 18.
- any traction on the film 7, for example in the event of a fall, impact or rough handling, will be compensated not only by the wedging effect of the part 11 ′ as in the first variant but also by the wedge effect of the tenons 15, 16 embedded in the grooves 17, 18 of the vertical walls 3.5.
- FIG. 5 shows a parallelepipedal half-box 20 for packaging in cardboard or the like for transporting a load, said half-box comprising a lateral belt 21 formed by four vertical walls 22 and a horizontal bottom 23 formed by four flaps secured to said belt via junction lines 24, and a heat-shrinkable plastic film material 25 intended for packaging and holding the load in place (not shown).
- the half-body has a rigid rectangular plate 26 attached, flattening the heat-shrinkable film on the internal face 27 of the bottom of the body while letting escape on either side of two opposite edges facing 28 of the plate, portions 29 and 30 of curtain of free material extending from the edges 28 over a length sufficient to cover each other by completely enveloping the load and blocking said load by thermal shrinkage of the film.
- the plate 26 is inserted between at least two first opposite vertical walls so that said edges are in contact or substantially in contact via the plastic film 25 with at least part of the joining lines 24 of said first walls.
- the box comprises blocking means 31 of the plate 26 against the bottom 23.
- the blocking means 31 comprise portions of internal flaps 32 directly bonded to the internal faces 33 of the first vertical walls 22, the lower periphery 34 of the internal flaps coming into abutment with the upper edges 35 of the plate to ensure blocking, thus wedging the plastic film 25 between the lower edge of the flaps 32, the internal face of the first wall and the end of the upper face of the edge of the plate.
- the half-body is formed from a blank comprising the four rectangular walls 22 separated by vertical fold lines 36 provided with a lower rectangular flap 37 intended to form the bottom 23 , attached to the lower part of the box by a fold line 24 aligned with that of the adjacent flap.
- Two interior flaps 32 bonded to two non-adjacent walls are provided.
- They are for example rectangular and of a surface slightly less than that of the walls 22 concerned.
- the lower periphery 34 of the flaps is situated at a distance e_ corresponding to the thickness of the plate 26 which slides into abutment under said peripheries.
- FIG. 7 is a top view of FIG. 5 showing the two facing walls 22, each provided with two internal flaps 32 for blocking the plate 26 against the bottom formed by the flaps 37.
- the plastic film 25 (in phantom in the figure) is moreover pierced with circular orifices 38 of small diameter, for example four orifices arranged on a line parallel to the junction line 24, at a distance of 1 to 5 cm. of the latter, for example 2 cm.
- the holes are one or two centimeters.
- Glue dots 39 were injected through allowing direct bonding of the underside of the added plate 26 on the upper, flat face, large contiguous flaps 37 which constitute the upper part of the bottom, the small flaps being in turn folded outside and glued.
- the plastic film 25 is also glued on one or on its two sides to the adjoining cardboard faces, for example by two lines 40 of so-called "hot melt” glue.
- FIGS. 8 to 10 show another embodiment of the primary container 49 or box obtained from the blank 50.
- the box 49 is in the form of a tray comprising a rectangular bottom 51 comprising four first rectangular flaps equal in pairs 52 and 53 connected respectively to each side of the bottom by fold lines 54 perpendicular to each other.
- Two first opposite flaps 53 for example corresponding to the short sides, each comprise on either side, second rectangular flaps 55 attached to the lateral peripheries of said first flaps.
- the second flaps 55 have, in the lower part, rectangular recessed portions 56 of height equal to or substantially equal to that of the plate 57, arranged to allow the vertical blocking of the plate 57 (see FIGS. 8 and 9) previously provided on its lower face.
- a plastic sheet 58 for example secured by gluing, which comes to be embedded below the lower edges 59 of the second flaps 55 by wedging the film 58 as shown in FIG. 9.
- the film 58 thus describes a horizontal path parallel to the bottom 60 of the box, then vertical over a small lower portion 61 of the vertical wall 53, then horizontal 62 towards the inside of the box, before leaving freely towards the load and / or the top and the inside of said box, so that it can then be folded back onto the load 63 (in dashed lines in the figure) as shown with the arrows 64.
- the plate blocking means may even comprise, or be constituted by, a product to be packaged, higher than the others, which would come into abutment on the internal face of the cover (not shown) when the cover is put in place.
- Figures 11 to 13 show another embodiment of a box 70 for crate according to the invention with rectangular plate 71 provided with a plastic film 72 pre-glued on the underside of the plate.
- the film includes for example orifices or recesses 73, for example in the form of small size lunules (from 0.5 cm to 3 cm maximum size, for example 1 cm) for example two rows of 10 lunules 73 (2 times 5) staggered, that is to say offset, suitable for being arranged below and vertically in line with the internal wall sections specified below, or directly near towards the interior of the box.
- orifices or recesses 73 for example in the form of small size lunules (from 0.5 cm to 3 cm maximum size, for example 1 cm) for example two rows of 10 lunules 73 (2 times 5) staggered, that is to say offset, suitable for being arranged below and vertically in line with the internal wall sections specified below, or directly near towards the interior of the box.
- the box 70 in the form of a tray comprises four rectangular walls formed by two small flaps 74 and two large flaps 75 attached to the bottom 76 by fold or junction lines 77.
- Each small flap comprises two second rectangular lateral flaps 78, with lower recess 79 for blocking the plate against the bottom as described above.
- These recesses are substantially rectangular, of width e_ between the extension of the fold line 77 and the lower edge of the flap 78, and extend over the entire length of the second flap 78.
- the second flaps 78 are also glued to the faces internal of large flaps 75.
- the large flaps 75 comprise, on their upper horizontal periphery, third rectangular flaps 81 attached to the latter by double fold lines 82, of thickness equal to or slightly greater than that of the second flaps 78, so as to be folded down , and glued to the external faces 83 directed towards the inside of the box of the second flaps 78, as shown in FIG. 12.
- the plastic film 72 previously introduced into the tray formed or secured to the plate 71 before being introduced is thus wedged horizontally between the lower edges 84 of the second flaps 85 and of the third flaps on one more large horizontal distance, the width 1 of the third flaps being calculated to allow said flap to graze and / or also wedge the plate against the bottom on the plastic film.
- the third flaps can be folded only after introduction of the film and the plate, thus further consolidating the blocking, which will allow the transport of objects particularly heavy like kitchen utensils for example.
- FIGS 14 to 17 show another embodiment of the invention.
- the box 90 is here obtained from a blank 91 in the form of a belt provided with four rectangular flaps 92, 93, 94 and 95 forming the vertical walls of the box obtained from the box.
- a lateral bonding tab is also provided in a known manner.
- Each flap comprises a lower flap, namely the large flaps 92 and 94 each comprise a rectangular flap 96 intended to form the contiguous and flat face of the bottom against which the plate 97 will be locked, and the small flaps 93 and 95 comprise a flap identical 98 of rectangular shape higher than that of the small adjacent flap to which it is attached.
- Each flap 98 has a central tab 99 detachable from said flap, but attached by a fold line 100 offset from the junction lines 101, aligned, flaps 92 to 95, with the bottom.
- the tabs 99 for example of rectangular shape, on the other hand remain horizontal in the same plane as the other flaps 96, a complementary recess 99 ′ therefore appearing in said flaps 98.
- the box is then formed, for example around a mandrel, the large rectangular flaps 96 being above and the tabs 99 glued below said flaps 96 (see FIG. 17).
- the plate 97 provided with the film 103 for example of transverse dimension a little less than the length between raised flaps 98 to allow its introduction, is then introduced and comes to block the film 103 on the flat bottom of the box.
- the flaps 98 are folded down (arrow 104) and come to constitute the means for blocking the plate 97 on the bottom, plate with which they are glued (cf. FIG. 15), the film 103 escaping on the sides as shown on the figure.
- the film is in one piece.
- the plate is made of corrugated cardboard, the direction of the grooves of which is perpendicular to the contact lines with the first vertical walls between which said plate is inserted, and the plate completely covers the bottom of the body to constitute a double bottom.
- a first step 110 consists in forming the bottom and the vertical walls of the box which are left open on the top.
- Such training can for example be carried out around a mandrel from a flap belt as described in documents FR-A-2 629 012 or FR-A-2 665 137.
- the blocking means may in this case be either the internal blocking flaps glued to the walls, or snap-fastening means, the whole being completed by bonding through the plastic film (s).
- a composite element is formed (step 111) comprising the plate and the plastic material previously secured at least temporarily to said plate by gluing (step 112).
- the composite element is introduced into said box until it comes into locking position in abutment against the bottom of the box, maintaining if necessary the free edges of the plastic film towards outside, for example by blowing nozzles.
- step 114 we then come (step 114) to place the load in the packaging, we close (115) the ends of the plastic film on it, which is heat sealed at 116, then we perform thermal constriction (step 117) for example by passing through a tunnel heating in a manner known per se.
- the packaging is then closed (step 118) by placing the cover and / or simply closing it with gluing if it is upper flaps, before removing (119) the packaging.
- Another method consists in introducing the plastic film before introducing the plate.
- the composite element is placed on the bottom of the mandrel and then the body is formed on top.
- the invention also provides a device for manufacturing a cardboard packaging box or the like for transporting a load, said box comprising a lateral belt formed by at least four vertical walls and a horizontal bottom secured to the belt via junction lines, and a heat-shrinkable plastic film material intended for packaging and holding said load in place.
- a device for manufacturing a cardboard packaging box or the like for transporting a load said box comprising a lateral belt formed by at least four vertical walls and a horizontal bottom secured to the belt via junction lines, and a heat-shrinkable plastic film material intended for packaging and holding said load in place.
- the means which it implements are a combination of known means and / or adapted in a manner accessible to the person skilled in the art seeking to mechanize the manufacture of a box according to the invention, such as tray-forming machines and / or polygonal boxes with four or eight sides around a mandrel.
- the novelty comes in particular from the application in combination of these machines making it possible to obtain the packaging according to the invention.
- the device therefore comprises means 120 for forming the bottom and vertical walls of the box C from blanks F supplied in a known manner, means 121 for presenting a composite element comprising a plate 122 superimposed on the plastic film material 123 advantageously secured at least temporarily to said plate.
- the means 121 comprise, for example, a film reel 124, means 125 for piercing orifices, for example by heating, and means 126 for bringing cardboard plate 122 above the film, with bonding by means of injection 127, and means 128 for force or bias introduction of the composite element, comprising for example a rocking arm or a piston, into said box until the heat-shrinkable film is pressed against the inner face of the bottom of the body while letting escape and maintaining (rollers 129) on either side of two opposite edges opposite said plate, curtain portions of free material extending from said edges over a sufficient length to overlap each other by completely enveloping the load and block said load by thermal shrinkage of the film during their folding.
- the body for its part, comprises the means specific to pressing said element by pressing on the attached rigid plate.
- the device also comprises means 131 for placing the load, means 130 for folding down the film parts on the load, and heat sealing means 132 for said film parts.
- thermoconstricting the film and for reclosing by a cover 134 or folding down the flap pre-glued by means 135.
- the means 128 are replaced by means for plating the composite element on the bottom of the mandrel before the box is formed around.
