Definitions

  • This invention relates to a method of applying adhesive stripes to the closable end of a cardboard box of rectangular cross-section the four side walls of which have extensions at one end for forming a projecting frame which is adapted to be turned inwards about transverse fold lines at the end edges of said walls and which by fold lines is divided into portions corresponding to said end flaps and into intermediate portions forming hinged connections between the end flaps, wherein the width of the short end flaps located at the ends of the narrow walls is at most equal to half the width of the narrow walls, whereas one long end flap is wider than the other long end flap and of a width substantially equal to the width of the narrow walls, and wherein the corner portion between the respective end of the wide long flap and the adjacent short end flap is formed by two triangular portions located one on each side of the corner fold line of the frame, one of said two triangular portions being hingedly connected to the wide long flap along a 45 fold line and the other portion being hingedly connected to the short end flap along a 45 fold line.
  • the object of the invention is to render possible application of adhesive stripes in one and the same direction so that the box can pass through the adhesive applying device without the necessity of being stopped for apply ing transverse adhesive stripes.
  • This object is attained by application of adhesive stripes in accordance with the method suggested by the invention.
  • the invention also relates to a cardboard box suitable for carrying into effect the method of applying adhesive as well as a blank for erecting such box as will. appear from the appending claims.
  • FIG. 1 illustrates the blank for erecting the box according to the invention
  • FIG. 2 illustrates an enlarged developed view of a portion of the closable end of the box
  • FIG. 3 illustrates a broken perspective view of the open end of the box with the end flaps in upright position
  • FIG. 4 illustrates an intermediate position during the closing operation in which position the adhesive stripes are appliedto the end flaps and their intermediate portions
  • FIGJS illustrates the end flaps in a subsequent position in which the wide long flap has been folded into upright position on its way down to the narrow long flap
  • FIG. 6 is a perspective view of the closed end of the box.
  • the blank according to FIG. 1 is substantially rectan gular and is subdivided by longitudinal fold lines 10a,
  • the wall 17 has extensions in the form of wing flaps 19a which together with the walls 19 form the narrow sides of the box.
  • the walls 19 are glued to the wing flaps 19a which in the erected condition of the box are considered to be made in one piece and to coincide with the walls 19 for the purpose of simplifying the description of the invention.
  • the wall 18 has an extension in the form of a long and wide end flap 21 of the same width as the narrow walls 19.
  • the narrow walls 19 have extensions in the form of short end flaps 22 the width of which, i.e., the distance between the fold line 15b and the edge of the fiap 22, is somewhat smaller than half the width of the narrow walls.
  • the wide wall 17 has an extension in the form of a long and narrow end flap 23 which via wedge-shaped intermediate portions merges into end flaps 22a at the ends of the flaps 19a.
  • the end flaps 22a are glued to the inside of the end flaps 22 and are considered hereinbelow to coincide with the end flaps 22 in the erected box according to FIG. 3.
  • the edge of the flaps 19a is indicated by a dotted line 24.
  • the wide long flap 21 extends between the fold lines 10c and 110. At its ends it is foldable relative to a greater triangular intermediate portion 25 located between the fold lines or and a 45 fold line 26.
  • a smaller triangular intermediate portion 27 which along a 45 fold line 28 is hingedly connected with the short end flap 22 and has a straight free edge 29.
  • the short flap 22 extends between the fold line 28 and an oblique fold line 30 which forms a hinged connection with the above named wedge-shaped triangular portion 31 which on its other side is hingedly connected to the narrow long flap 23 along a fold line 32, as will be best seen from FIG. 2.
  • the angle between the fold lines 30 and 32 is less than 45, and the free edge 31a of the portion 31 is aligned with the free edge 22a of the short flap 22.
  • the free edge 22a is parallel to the edge fold line 15b.
  • the narrow long flap 23 extends between the fold lines 32 and is somewhat wider than the short flaps 22.
  • the free edge 23a of the flap 23 merges via a shoulder 33 into the free edge of the portion 31 so as to form a corner flap 33a for the purpose indicated below.
  • the erected box is moved in the longitudinal direction of the long flaps 21, 23 and is passed through an adhesive applying device, not shown, which applies two parallel adhesive stripes to the upwardly turned sides of the end flaps.
  • adhesive stripes are indicated in the drawings by thick, full lines.
  • one adhesive stripe 34 is located on the narrow long flap 23 near the edge fold lines 12a thereof so as to form an attachment for the corresponding edge portion on the underside of the wide long flap 21.
  • the other adhesive stripe is formed by two parts 35, 36 which are applied to the triangular intermediate portions 27 near the fold lines 100 and 110.
  • the adhesive employed may be of the kind that requires an immediate subsequent closure in which case the box shown in FIG. 4 as filled with its contents.
  • the end flaps may be turned upwards again to the position shown in FIG. 3 to enable filling of the box at a desired time.
  • the adhesive is preferably of the heat-sealing type which adheres upon heating.
  • the end flaps are turned into the intermediate position shown in FIG. 5 where the wide long flap 21 is exactly upstanding and the narrow long flap 23 is turned downwards on the short flaps 22. In this position the intermediate portions 27 are extending obliquely upwardly.
  • the free edge 29 of the intermediate portion 27 makes an acute angle with the edge fold lines 12a, 1512 which angle is approximately equal to the acute angle between the fold lines 32 and 12a.
  • the free edge 29 of the intermediate portion 27 will lie outside the edge formed by the fold line 32 so that the intermediate portion 27 can be freely forced into contact with the short flap 22 in the region of the glue joints 35a and 36a.
  • a cardboard box comprising four interconnected side walls having extensions at one end for forming a rectangular projecting frame which is adapted to be turned inwards about transverse fold lines at the end edges of said walls and which by fold lines is divided into portions corresponding to said end flaps and into intermediate portions forming hinged connections between the end flaps, wherein the width of the short end flaps located at the ends of the narrow walls is at most equal to half the the width of the narrow walls, whereas one long end flap is wider than the other long end flap and of a width substantially equal to the width of the narrow walls, and wherein the corner portion between the respective end of the wide long flap and the adjacent short end flap is formed by two triangular portions located one on each side of the corner fold line of the frame, the greater one of said two triangular portions being hingedly connected to the wide long flap along a 45 fold line and the other, smaller portion being hingedly connected to the short end flap along a 45 fold line, characterized in that the width of the short end flaps is smaller than half the width of the narrow side walls,
