Definitions

  • the present invention relates to the field of packaging; she relates more particularly to a cardboard or similar material case, consisting of a belt of four side walls extended by flaps closing.
  • Boxes of this kind can be pre-assembled in the factory to form the side wall belt; they are then delivered flat to the customer. After having put the packaging in volume, one of the ends is closed, for example by means of an adhesive strip positioned on the joint of the outer flaps, or else by stapling or gluing. The other end is closed in the same way, after the packaging of the products.
  • cutting or cutting tools are often used, such as scissors or cutters, which involve the risk of injury or which can deteriorate the packaged products.
  • cutting or cutting tools are often used, such as scissors or cutters, which involve the risk of injury or which can deteriorate the packaged products.
  • the complete overhaul of the packaging is not always very easy to obtain.
  • the present invention aims to remedy these various drawbacks by offering a body structure whose opening and flattening are carried out without any difficulty and without special tools.
  • This packaging is of the type comprising a belt of four side walls, two of said opposing walls being provided with first closure flaps at their ends, and the other two walls being provided with second closure flaps. These second flaps cover the first flaps; they are contiguous or practically contiguous and tear-off adhesive strips are positioned on their joint zone to ensure the closure of the packaging.
  • one of the side walls which carries the first flaps comprises an opening means in the form of a tear-away structure arranged over its entire length or width as the case may be, between said first flaps, and these first flaps have on their entire height, an opening means located in the extension of said removable structure, consisting of a cutting line, a cutout and / or an extension element of said removable structure. In this way, the removal of the adhesive strips and of the tear-off structure ensures the opening and automatic flattening of the box.
  • the packaging includes at least one means of gripping the removable structure, in the form of a cutout or pre-cut area, arranged on the removable structure, or on the edge thereof.
  • one of the ends of the adhesive strips closure sticks against the side wall provided with the structure detachable, on said detachable structure. This removes said adhesive tapes in continuation of the removal operation of the structure removable.
  • the removable structure can be a precut strip or a strip reported uprooting. In certain embodiments these bands are extend over the height of the adjoining closing flaps; in other embodiments, these flaps have cut lines or cutouts arranged in the extension of the removable structure.
  • the corrugated cardboard blank illustrated in Figure 1 allows obtaining the packing case shown in Figures 2 and 3.
  • This cardboard blank includes a cardboard strip forming four walls side 1, 2, 3 and 4 connected by fold lines 5, 6 and 7.
  • the wall 4 On its end edge, the wall 4 has a fastening tab 8 connected by the fold line 9. This tab 8 extends over the entire length of the wall 4 and we notice that it has small tabs 10 which extend its two ends.
  • the side walls 1, 2, 3 and 4 have a generally rectangular shape; walls 1 and 3, on the one hand, and walls 2 and 4, on the other hand, have identical dimensions to form a rectangular box.
  • the fourth walls 1, 2, 3 and 4 have the same height and walls 1, 3 have a little width greater than that of walls 2, 4.
  • the side walls 1 and 3 extend at their ends by flaps, respectively 12 and 13, connected by fold lines 14 and 15. These flaps 12 and 13 occupy the entire width of the walls 1 and 3; their height corresponds substantially to half the width of walls 2 and 4.
  • the side walls 2 and 4 extend at their ends by flaps, 17 and 18 respectively, connected by fold lines 19 and 20; these flaps 17 and 18 occupy the entire width of the walls 2 and 4; their height is slightly less than half the width of walls 1 and 3.
  • the flaps 12, 13, 17 and 18 have an identical height.
  • the side wall 2 has a precut strip 24 arranged in its middle part and over its entire length, between the end fold lines 19.
  • This precut strip 24 is made up of two juxtaposed portions 24 'and 24 "which each extend from the central zone of wall 2 to one of the fold lines 19.
  • the width of each portion of strip 24 ′ and 24 "increases slightly from the central part to the fold lines 19; at their joining zone, the presence of a precut patch 26 is noted.
  • the two flaps 17 have a Tee cutting line 28.
  • the head 29 of these cutting lines 28 is located on the fold line 19 and extends over the entire width of the strip pre-cut 24; their foot 30 extends perpendicular to the head 29, on full height of flaps 17.
  • the assembly of the box is carried out by joining the external face of the tab 8 by gluing with the internal face of the wall 1; a belt is obtained with four side walls 1, 2, 3, 4 provided with flaps 12, 13, 17 and 18 allowing the ends to be closed.
  • the small tabs 10 which extend the tab 8 are secured to the flaps 12 to optimize the resistance.
  • This operation can be carried out at the customer or in the factory. In the case of assembly in the factory, a pre-assembled, flat box is obtained which can be delivered as is to the customer.
  • the pre-assembled box is set in volume ( Figure 2) and one of its ends is closed by positioning the flaps 17 and 18 perpendicular to their adjoining lateral faces 2 and 4, by folding down the flaps 12 and 13 which extend the walls 1 and 3 and maintaining the assembly by means of an adhesive strip 32.
  • This adhesive strip 32 is positioned on the joint edge of the flaps 12 and 13; it extends over the ends of the side walls opposite 2, 4, in particular so that one of its extensions come to be placed on the end of the precut strip 24.
  • T-28 cutting lines creates a line opening in the flaps 17 while preserving as much as possible the integrity of these, in order to limit the decrease in resistance of the body.
  • the opening of the packaging is carried out by punching the precut patch 26 to form an opening constituting a means of gripping the portions of precut strips 24 ′ and 24 ". As illustrated in FIG. 4, it is then sufficient to tear off these portions of pre-cut strips 24 'and 24 ", then tear off in the same movement the adhesive strips 32 to obtain an automatic flattening of the box.
  • the complete tearing of the precut strip 24 makes it possible to open the side wall 2.
  • the opening of the end sides and the total flattening of the packaging are obtained by tearing off the adhesive strips 32 and thanks to the lines cutting 28 of the flaps 17 located in the extension of the precut strip 24.
  • Figures 6 to 10 show flat cardboard blanks that allow obtaining alternative embodiments in accordance with the invention.
  • the flaps 17 have a cutout 34 over their entire height, instead of the Tee cutting line 28.
  • this cut 34 has a width which corresponds to the width of the ends of the portions of pre-cut strips 24 'and 24 ".
  • FIG. 7 illustrates a derivative embodiment in which the flaps 17 comprise a small precut portion 35, in the extension of the strip 24, followed by a cut 36.
  • the precut portions 35 extend over the entire width of the strip pre-cut 24; they are attached to them so as to be torn off with the strip portions 24 ′ and 24 "during the opening operation.
  • the presence of the precut portions 35 makes it possible to reinforce the structure of the flaps 17 compared with the embodiment illustrated in FIG. 6.
  • cut 36 can be replaced by a cut line in tee.
  • FIG. 8 comprises a precut strip 38 with a structure slightly different from that illustrated in the previous embodiments.
  • This strip 38 has a central portion 39 of small width which leads to precut pads 40 from which extend end portions 41 wider.
  • the opening of the box is carried out from the two gripping means 40, by tearing off the portions 41 associated with the adhesive strips and by tearing off the central part 39.
  • T-shaped cutting lines 28 arranged in the flaps 17.
  • the embodiment illustrated in FIG. 9 comprises a precut strip 42 which extends over the entire length of the side wall 2, associated with precut extension elements 43 which extend over the entire height of the flaps 17.
  • the elements extension 43 are adjacent to the precut strip 42.
  • the central part of the wall 2 is equipped with a precut patch 44 from which extend the strip portions 42 ′ and 42 "followed by the extension elements 43. From the patch 44 serving as a gripping means, the width of the precut portions 42 '/ 43 and 42 "/ 43 decreases to the end of the flaps 17.
  • the flaps 12 and 13 of the side walls 1 and 3 have a cutout 45 at their end, over approximately half of their length, facilitating the evacuation of the precut strips 43 during the cash register opening operation.
  • FIG. 10 also shows an alternative embodiment in which a tear strip 46, of the “ripatape” strip type, for example, is positioned along the length of the side wall 2 and over the height of the flaps 17 to form the structure of uprooting of the box.
  • This tear strip 46 consists of an attached strip, fixed to the inside of the carton.
  • the portions 47 of the strip 46 which extend over the flaps 17 adjoin the central portion 48 provided along the length of the wall 2.
  • a transverse cutout 50 is arranged in the central part of the wall 2 to constitute a means of gripping for uprooting during the opening operation of the box.
  • the grooves 52 of the corrugated cardboard are oriented in the width direction of the side walls 1, 2, 3, 4 so that that the tear strip 46 is oriented transversely to these grooves.
