Definitions

  • the invention relates to a blank as according to the preamble of claim 1.
  • Such a blank is known from DE-U-9318467 and DE-U-9002504.
  • the curving main surfaces of such a known blank are bounded by at least two cut edges which in the corresponding box formed by the blank connect poorly to the adjoining main end surfaces.
  • the invention has for its object to cause the curved wall of the corresponding box to connect well onto the end walls and provides for this purpose a blank as according to claim 1.
  • the blank according to the invention preferably has at least two, and more preferably at least three, curving auxiliary surfaces located at a mutual distance on at least one and preferably two folding edge(s) of one and preferably two curving main surface(s).
  • the number and shape of the curving auxiliary surfaces of a blank according to the invention will depend on the desired curve of the curving wall and on the desired closure of the curving wall relative to the end wall.
  • a preferred embodiment of a blank 1 according to the invention has two flat main surfaces 2, 4; two curving main surfaces 3, 5; two end main surfaces 6, 6'. These main surfaces 2, 4, 3, 5, 6, 6' of the blank form the walls of the corresponding box shown in figure 3.
  • the curving main surface 3, 5 is coupled at a folding edge A to a number of curving auxiliary surfaces 10, 11, 12.
  • Each curving surface 3, 5 preferably has two opposite folding edges A which are each provided with a number of, and preferably three, curving auxiliary surfaces 10, 11, 12.
  • a space 13, 14 is provided between the curving auxiliary surfaces, which space is bounded by a cut edge.
  • the curving auxiliary surfaces 10, 11, 12 are positioned in a mirror-symmetrical pattern relative to the middle of folding edge A of curving main surface (s) 3, 5.
  • the curving auxiliary surfaces 12 are of a larger dimension than the other curving auxiliary surfaces 10, 11.
  • the size and shape of curving auxiliary surface 12 are chosen such that in the formed corresponding box (figure 3, 4) they lie against each other in the same plane.
  • the curving main surface 5 is coupled along the full length to a peripheral auxiliary surface 7.
  • Blank 1 comprises two auxiliary end surfaces 8 and 9 which preferably have the same dimension and the same shape as the main end surfaces 6, 6'.
  • a curving auxiliary surface 12 will be received on each box end between an auxiliary end surface 8, 9 and a main end surface 6, 6', which main end surface 6, 6' forms the outer end wall.
  • FIG. 1 Another embodiment of a blank 17 has auxiliary end surfaces 15, 16 with a shape differing slightly from main end surfaces 6, 6', from which the corresponding box is shown in figure 4 and which box has the same shape and dimension as the box of figure 3.
  • the blank 1, 17 is first folded along folding edges B, whereafter the auxiliary surface 7 is fixed to the main surface 2 of the blank, for instance by gluing to form a flat wall 20, thereby obtaining a tube.
  • the curving auxiliary surfaces 10, 11 are then folded inward on which the auxiliary end surfaces 8, 9 respectively 15, 16 are placed, whereafter the curving auxiliary surfaces 12 are folded thereover and whereafter finally the main end surfaces 6, 6' are placed on the already folded-up assembly to form the end wall 18, 21.
  • the curvature of a cut edge of the end wall corresponds with the curvature of the curving wall 19.
  • the end wall 18, 21 also connects well onto the other walls of the box. All parts are preferably mutually adhered by means of an adhesive such as glue.
  • the curving surface is held in its curved position in that a curving auxiliary surface 12 is enclosed between an auxiliary end surface and a main end surface and also in that the curving auxiliary surfaces 10, 11 are arranged relative to curving auxiliary surface 12 in interwoven manner between the auxiliary end surface.
  • Assembly of a box formed by a blank according to the invention can be formed in other manner, in particular with another folding sequence.
  • the curving auxiliary surfaces 10, 11, 12 can differ in number and shape from the above illustrated preferred embodiments.
