Definitions

  • the invention relates to a snap fastener, in particular a snap fastener tape, preferably made of plastic. It also relates to a reclosable bag, in particular a resealable packaging bag, or a resealable one Packaging or any other resealable container, preferably made of plastic, with a snap fastener or a snap fastener tape.
  • snap fasteners and snap fastener tapes are known. Acting it is mostly snap fastener tapes that are endlessly extruded and consist of two strands. The two strands are mostly with two or more Equipped hooks that interlock. Another type of snap fastener tapes a strand has a hooked groove while the other strand engages with an arrowhead-like hook in the groove. A such a known embodiment is shown in FIG. 1 shown. Also the one-piece production of the pressure closures or the pressure closure tapes with the bags or packaging are known.
  • closures are attached to the so-called Grip flap opened by pulling open and by pressing or streaking closed with thumb and forefinger.
  • the known closures have the disadvantage, however, that the groove and hook tip or hooks and double hooks for interlocking exactly one above the other must come to lie and then be pressed together with some resistance must, which is usually very difficult for the user and often does not succeed. It The bags or packaging then remain open and the contents spoil or dusty or is exposed to other negative environmental influences.
  • the object of the invention is for a pressure lock or pressure seal tape or with a resealable bag or a resealable bag Packaging to create an easy reclosure option.
