Definitions

  • the invention relates to a package or the like with a plastic strapping, the strap ends of which lie on top of one another and are welded to one another only in partial areas of the covering.
  • Opening the packages with plastic strapping requires cutting the plastic strap with a knife, scissors, etc. It is not possible to loosen it in any other way. However, since cutting tools are not always within reach, they have to be brought in with a greater effort.
  • the object of the invention is to provide packages with such plastic strapping, which can be opened at short notice without using cutting tools.
  • a package with a plastic strap strapping of the type in question is specified, which can be opened for a short time without cutting tools, but without disadvantageous the holding force of the plastic strap strapping.
  • the tape ends are only welded in partial areas of the overlap in such a way that the tape end lying on the top ends in a protruding tab. This forms the handle when the plastic strapping is to be released. After gripping the handle tab it is to move against their course in the opposite direction with successive peeling of the sub-area welding points. This separation process must be done deliberately. Strapping tensions present on the package are unable to loosen the corresponding weld. This means that the tensile strength of the welded connection zone consisting of several sections is greater than the peeling resistance.
  • the grip tab can be formed in a simple manner by choosing an appropriate distance between the weld connection zone and the cutting separating knife of the strapping machine. This means that basically no additional measures need to be taken.
  • the sub-area welding is formed by straight welding zones lying one behind the other and transversely.
  • the force required to loosen the sub-area welding therefore corresponds to that which is required to cut open a straight welding zone.
  • the sub-area welding zones which are preferably located behind, contribute overall to the tear resistance of the sub-area welding.
  • Another advantage can be seen in the fact that the straight welding zone adjacent to the gripping tab creates a bending point, so that the gripping tab assumes a slightly spread-apart course towards the strip ends.
  • the handle tab can be comfortably gripped, in order to then separate the successive, transverse, straight welding zones by peeling.
  • the handle tabs are not disruptive. When several packages are stacked on top of each other, the tabs are then pressed against the strapping. As soon as however, if they are relieved of pressure, they spread slightly into the comfortable gripping position.
  • Handling advantages are created in that the free projection of the handle tab corresponds to approximately twice the width of the band and the width of the welding zone approximately to the thickness of the band. Experiments have shown that this length of the free overhang is sufficient to be able to grip the grip tab sufficiently firmly. A longer protrusion is therefore not necessary, so that the solution according to the application permits material-saving strapping.
  • the grip tab and the width of the welding zone are matched to one another in such a way that the aforementioned length of the protrusion of the grip tab is sufficient to separate the welding zones one after the other.
  • the numeral 1 denotes a package to which a plastic strapping 2 is assigned. Their band ends 3, 4 lie on top of each other and are welded together.
  • the band ends are connected by a partial area welding 5, which is formed by straight welding zones 6, 7 and 8, which are spaced one behind the other and transversely.
  • a partial area welding 5 which is formed by straight welding zones 6, 7 and 8, which are spaced one behind the other and transversely.
  • the strap ends After heating the plastic strap ends 3, 4, which are held by grippers (not shown) of a strapping machine, the strap ends are pressed against one another by pressure jaws, not shown, so that there is then a wavy course of the upper side of the upper strap end 4 in the calculation of the partial area weld 5 .
  • the pressure jaw can be equipped with protruding webs. It would also be possible to additionally equip the other pressure jaw with protruding webs.
  • the plastic band is cut in such a way that the upper end of the band 4 ends in a tear-open tab 9.
  • the free projection A of this tab 9 corresponds approximately to twice the width B of the tape.
  • a width c of the welding zones is selected, which dimension corresponds approximately to the thickness D of the strip.
  • the indentation 12 adjacent to the grip tab 9 causes a deformation due to which the grip tab 9 moves away from the underside of the band 3 spreads.
  • the corresponding spreading angle is preferably in the range between 10 and 30 °.
  • the tab 9 should preferably be gripped between the index finger and thumb by pivoting the handle tab obliquely to the direction of the arrow x or in this direction, along with an increasing angle between the handle tab and the strap end 3 this pivoting movement is to exert a force P in the direction of the arrow illustrated in FIG. 4, in that the welding zones 6, 7, 8 are separated one after the other by peeling.
  • An intermediate position is illustrated in FIG. 4. This shows that the welding zone 8 adjacent to the grip tab 9 has been separated. This peeling can be done with relatively little effort. Nevertheless, the sub-area welding 5 provides a firm connection, which is characterized in that the tear strength is greater than the peeling resistance.
