Definitions

  • the invention is related to the field of packaging cartons which are used for various purposes in all types of industry and business.
  • Such cartons are manufactured from different grades of cardboard material, for instance cardboard material with several flat and corrugated layers.
  • Tha cartons are obtained by folding a prefabricated blank, which has the required shape and is provided with cutting lines and crease lines so as to enable an efficient manipulation of the blanks in a folding machine.
  • the cartons are frequently reused.
  • cartons which are applied for packaging bakery goods, such as butter are often used for transport of the baked goods after unpacking the butter contents.
  • the carton comprises both a tray and a cover which snugly fits over the tray.
  • the tray has a bottom and four upstanding tray walls; similarly, the cover has a top and four depending cover walls. These cover walls are about the same height as the tray walls, in such a way that after placing the cover onto the tray, a strong packaging carton is obtained.
  • the tray and the cover are separate components, which have to be manufactured seperately from two blanks and which subsequently have to be assembled during the packaging process.
  • the object of the invention is to provide a blank for a packaging tray which can be handled in a relatively simple way and which can be reused after unpacking.
  • a blank for a packaging carton said carton comprising a tray with a bottom and four tray walls as well as a cover which is hingedly connected to one of the tray walls, said cover having a top and three cover walls, such that in the closed state of the carton the cover walls each are opposite a corresponding tray wall, said blank comprising:
  • a packaging carton can de obtained which has a tray with a fixed cover.
  • a strong and stiff carton is obtained.
  • the three cover walls enclose the tray on three sides; the fourth side is formed by the tray wall which is connected to both the top and the bottom and thus adds to the strength and stiffness of the carton as well.
  • each triangular panel part defined between the two oblique crease lines of the cover wall panels has an open area next to the point of intersection of these crease lines.
  • the distance between the crease lines of the top panel are sligthly larger than the corresponding distances between the crease lines of the bottom panel.
  • the cover can be fitted easily over and around the tray.
  • the tray wall panels can be connected to each other in several ways.
  • the cover wall panels Preferably, the tray wall panel and the cover wall panel other than the tray wall panels and the cover wall panels which are connected to an intermediate panel are connected through crease lines to flap panels which overlap said tray wall panels and cover wall panels connected to an intermediate panel, said flaps in the folded state of the tray wall panels and cover wall panels can be connected, e.g by glueing, to said tray wall panels and cover wall panels which are connected to an intermediate panel.
  • the packaging carton wich can de manufactured from the blank according to the invention can be reused in its folded open state. In that state, a fairly large extended tray is obtained, the size of which is somewhat more than twice the size of the original tray. Due to this larger size, said extended tray could become less stable. It is therefore desirable to add reinforcements to this extended tray.
  • a cutting line is provided in at least one tray wall panel and at least one cover wall panel connected to and enclosing an intermediate panel, said cutting lines each extending into the bottom panel respectively top panel and at their ends being bounded by a first crease line which runs between said cutting lines and through said tray wall panel, said intermediate panel and said cover wall panel, and by a second crease line which runs between the same cutting lines through said bottom panel, the tray wall panel positioned between the bottom panel and the top panel, and the top panel, in such a way that in the state in which the cover is fully folded open so as to form an extended tray, the blank parts defined between said crease lines and said cutting lines can be folded inwards so as to provide a stiffining member in said extended tray.
  • two stiffening members are defined on opposite sides of the extended tray.
  • the two stiffening members which can be formed on opposite sides of the extended tray provide additional stiffness.
  • the intermediate panels each can have a cutting line which defines a hand grip. Because of the fact that the stiffeners are at the same position as the hand grips, the extended tray will not easily yield in bending when it is carried at said hand grips.
  • the blank as shown in figure 1 comprises a bottom panel 1 and four tray walls 2, 3, 4 and 5.
  • the tray wall 2 is connected to the bottom panel through a crease line 6; the other tray wall panels 3 up to 5 are connected to the bottom panel 1 through crease lines 7.
  • the blank is provided with a top panel 8, which through crease line 9 is connected to the tray wall panel 2.
  • the three cover wall panels 10, 11, 12 are connected to the top panel 8 through crease lines 13.
  • the tray wall panel 2 which is positioned between the bottom panel 1 and the cover panel 8 is connected to intermediate wall panels 14, 15 through crease lines 16. Furthermore, the intermediate wall panels 14, 15 are connected to the tray wall panels 5, 4 through crease lines 17, and to the cover wall panels 10, 12 through crease lines 18.
  • the tray wall panels 4, 5 are furthermore each provided with an oblique crease line 19, which run at an angle of 45 degrees with respect to their crease lines 7.
  • the oblique crease line 19 runs from the intersection between the crease lines 7, 17, towards the free edge of the tray wall panel 4, 5 in question. Between each oblique crease line 19 and the corresponding crease line 7 a triangular tray wall panel part 22 is defined.
  • the cover wall panels 10, 12 are each provided with two oblique crease lines 20, 21, which run at different angles with respect to their crease lines 13. They originate at the intersection between the crease lines 13, 18, and end at the free edge of the cover wall panels 10, 12. Between each oblique crease line 20 and crease line 18 a first triangular cover wall panel part 23 is defined, and between the two oblique crease lines 20, 21 a second triangular cover wall panel part 24 is defined. An open area 32 is defined near the intersection point of the oblique crease lines 20, 21.
  • Each intermediate panel 14, 15 has furthermore a crease line 25 and a cut line 26 between which a hand grip panel part 27 is defined.
  • the tray wall panel 3 is connected to flap panels 33 through crease lines 34, the cover wall panel 11 is connected to flap panels 35 through crease lines 36.
  • Said packaging carton comprises a tray which in total has been indicated by reference numeral 37; the tray 37 has been closed by the cover which has been indicated by reference numeral 38.
  • FIG 2 the fully closed state of the packaging carton according to the invention is shown.
  • figure 3 shows the fully opened position, in which a so-called extended tray is obtained.
  • This tray can be stiffened by pushing inwardly the stiffening parts 39, 40 which is made possible by the cutting lines 28, 29, and the crease lines 16, 30 and 31.
  • the extended tray can easily be handled and carried through the handgrips which are obtained by pushing inward the panel parts 27, so as to form handgrips, which are defined between the crease lines 25 and the cutting lines 26.
  • Figures 4 and 5 show two stages of forming the blank according to figure 1 into the carton of figure 2.
  • the panels 4, 15, 10 have been folded upward with respect to the panels 1, 2, 8 according to the crease lines 7, 16, 13.
  • the opposite panels 5, 14, 12 have been folded upwardly with respect to panels 1, 2, 8.
  • panels 3, 11 are folded upwardly and their respective flaps 33, 35 are connected, e.g. by glueing, stapling etc., to the adjoining, upwardly folded panels 4, 5 respectively 10, 12.
  • the shape according to figure 3 has been obtained then, be it that the stiffening part 39, 40 are not pushed inwardly.
  • the shape shown in figure 4 is obtained.
  • the triangular panels 22 are folded outwardly along their corresponding crease lines 19, such that the panel 2 can be folded upwardly according to its crease line 6 with respect to the panel 1.
  • the oblique panels 23, 24 are folded inwardly towards each other according to their respective crease lines 18, 20, 21 leading to the position shown in figure 5.
  • the panels 22 are firmly pressed against the outside of the remainder of the panels 4, 5, and the triangular panels 23, 24 are folded in opposite direction, away from each other, in such a way that they come to lie in a single plane, next to and against the inside of the remainder of the corresponding panels 10, 12 as well as against the outside of the intermediate panels 15, 14.
  • the triangular panels 23 and connected intermediate panels 15, 14 are temporarily pressed in inward direction at the location of their crease lines 18 (see inwardly directed arrow).
