Definitions

  • the invention relates to a sleevelessly locking strapping strip for packages, which is arranged to overlap at the point of junction and is provided in this overlapping region with a plurality of lock means preferably formed by angle slots arranged in pairs, wherein the angle slots of each pair are arranged in mirror image to each other, are displaced relative to each other or arranged one behind the other, extend substantially in the longitudinal direction and have substantially a zigzag shape, wherein they have regions extending parallel to the longitudinal central line which then turn into central regions extending at an angle toward the outer edge of the strip which in turn terminate in end regions arranged at an angle thereto, while the webs formed by the slots arepreferably pressed out of the plane of the strip alternately toward opposite sides and by bracing the strapping strip the lock means can be moved into a hooking position in which the angle slots and particularly the projecting corners formed by the central sections thereof, engage one behind the other.
  • the invention is based on the problem of providing a sleevelessly locking strapping strip for packages of the above type, wherein the overlapping ends of the strip can be moved out of the engaged position of the lock means only toward the hooking position and wherein the lock means canaccommodate high traction forces.
  • This aim is substantiallyachieved according to the invention in that at least in one pair of slots the end region of each slot is directed back at an angle to the longitudinal center line and ends at a distance from the adjacent outer edge of the strip which is smaller than the distance between the outer edge of the strip and the region of the slot which extends parallel to the longitudinal center line.
  • the carrying capacity of the lock means is not detrimentally affected by its particular construction and without additional means and by virtue of its construction alone the lock means prevents the ends of the strip being moved in opposition to the hooking direction, while the ends of the strip are prevented from being lifted out of the engaged position by the burr formed at the edges of the cut in the stamping operation. Therefore the ends of the strip cannot come apart.
  • the ends of the strip can also be prevented from lifting out of the engaged position by the fact that at least of the webs formed by the slots at one end of the strip the webs curved out of the plane of the strip toward the other end of the strip overlap at least in their central regions the webs of the second end of the strip which are curved out of the plane thereof toward the first end of the strip.
  • This can be effected in a simple manner by pressing together the lateral pairs of webs.
  • the inside distance between the lateral webs is smaller in the center of the slots than the width of the central web so that when the central web of one end of the strip is pressed into position, it cannot pass-out between the lateral webs of the other end of the strip.
  • FIG. I shows a package with strapping strips
  • FIG. 2 shows a plan view of the overlapping ends of a strapping strip with the sleeveless-lock means according to the invention, in the position in which the lock means are brought into position;
  • F IG. 3 shows the overlapping ends of a strapping strip in the position in which the sleeveless lock means take up their hooking position
  • FIG. 4 shows a section taken along the line IV-IV of FIG. 2;
  • FIG. 5 shows a section taken along the line V-V of FIG. 3;
  • FIG. 6 shows a plan view of a second embodiment of the sleeveless lock means in a position corresponding to the position shown in FIG. 2.
  • the package illustrated in FIG. 1 is provided in the longitudinal direction with one strapping strip and in the transverse direction with three strapping strips II arranged at distances from each other.
  • the ends 12, 13 of the strapping strips are joined together with lock means 14.
  • three lock means 14 are provided in each of the overlap regions of the ends l2, 13 of the strip.
  • the lock means 14 are formed by angle slots I5 arranged in pairs in mirror image to each other and extending substantially in the longitudinal direction and having substantially a zigzag shape.
  • the angle slots 15 have regions lb'extending parallel to the longitudinal centerline of the strip 11, which then turn into central regionsl7 extending at an angle toward the outer edge of the strip 11, which in turn terminate in end regions 18 which are directed back at an angle to the longitudinal centerline.
  • the spacing between the end points of the two end regions 13 of each'lock means 14 is greater than the spacing between the two parallel regions 16 of the angle slots 15.
  • the webs 19, 20 formed by the angle slots w are pressed out of the plane of the strip alternately toward opposite sides, while the central webs 1'39 of one end 12 of the strip are passed between the lateral pairs of webs 20 of the other end 13 of the strip and by bracing the strapping strip ill the lock means M can be moved into a hooking position in which the angle slots 15 and particularly the projecting edges formed by the central sections 18 thereof, engage one behind the other.
  • the arrangement of the end regions 18 of the angle slots 15 which extend back at an angle to the longitudinal centerline, provides that the cut faces formed by the end regions of the slots on the outwardly pressed central web I9 of the undemeath end 12 of the strip come into contact with the cut faces formed by the end regions lb of the angle slots 15 on the side webs 20 of the upper end 13 of the strip and prevent the ends of the strip being moved in opposite directions, in opposition to the hooking direction. Therefore the lock means 114 can only be moved from the engaged position illustrated in FIG. 2 in the hooking direction. This means that when the tension in the strapping strip Ill decreases, the lock means can only be pressed back out of the booking position as far as the engaged position.
  • FIG. 3 particularly shows, in the hooking position the end, formed by the end region 18, of the angle slot 15 of the underneath end 12 of the strip cooperates with the obliquely outwardly extending central region 17 of the upper end 13 of the strip, to provide an additional lock-hooking action. Therefore booking is not only effected by the central regions 17 of the angle slots provided in the underneath end 12 of the strip, which lie against the ends of the parallel regions lb of the upper end 13 of the strip.
  • the inside distance between the outer pairs of webs 20 formed by the slots 15, is less than the width of the central webs 19, at least in the central region of the angle slots 15.
  • the inside distance between the lateral webs 20 can be reduced by pressing the lateral webs 20 together, The reduction of the inside distance between the lateral web 20 causes the central webs 19 to be held between the lateral webs 20 so that the overlapping ends 12, 13 of the strip can also not be lifted from each other with the angle slots 15 in the engaged position shown in FIG. 2.
  • the ends of the strip can be moved in opposite directions toward the hooking position.
  • the embodiments illustrated are only given by way of example of the invention which is not restricted thereto. On the contrary many other embodiments and uses are also possible.
  • the lock means according to the invention could also be used as a flick lock.
  • the angle slots forming the lock means can also be formed in the overlapping ends of the strip in pairs or for all three lock means together. in addition, instead of being in mirror image beside each other, the two angle slots of any lock means can be arranged in the strip one behind the other or staggered relative to each other.
  • a strapping strip according to claim 1 characterized in that at least in the webs formed by the slots at one end of the strip the webs curved out of the plane of the strip toward the other end of the strip overlap at least in their central regions the web of the second end of the strip which are curved out of the plane thereof toward the first end.
