Definitions

  • the invention relates to a roll closure for stuff sacks or the like with the features of the preamble of claim 1.
  • Such roll closures for pack sacks or the like consisting of a rollable extension of the body of the pack sack, and a fastening for the extension in the rolled-up state, are known, for example, from products from Ortlich GmbH.
  • the object of the present invention is to provide a roller shutter of the type mentioned, which is characterized by particular tightness against water and splash water and which is simple and inexpensive to manufacture.
  • roller shutter of the generic type in the region of the extension and parallel to its end on the inside and / or
  • At least two strips of a flexible material are applied on the outside, which are essentially congruent to one another in a flat-laid or partially or completely rolled-up state of the extension and project laterally beyond the extension.
  • the stripes and the packsack are made of a waterproof material.
  • the strips consist of a plastic material or a flexible material coated with plastic. They can be glued, welded or sewn onto the extension.
  • the strips can have lateral recesses in the beginning area of the protrusion, which extend over the end area of the extension or are arranged on the outside next to it.
  • the strips can also have welded-on parts which extend in the initial region of the protrusion over the end region of the extension or which are arranged on the extension.
  • the strips are advantageously connected to one another at their opposite ends by gluing, welding or the like.
  • the connection can be produced in each case by buckles which are placed over the ends or placed between them or applied to one of their outer sides and by riveting, squeezing, welding, gluing, latching, pressing or pinning at the ends are attached.
  • the buckles advantageously extend beyond the ends of the extension with a slot to increase stability.
  • the buckles can be brought into engagement with one another by a flexible form fit. They also advantageously have through holes or receptacles which, when the two buckles are in engagement, lie one above the other or otherwise correspond spatially and permit the engagement of a lock.
  • the strips can be provided with sealing lips designed as a slide closure. Provided that they are arranged in the interior of the extension, these sealing lips are arranged at a distance from their upper edge so that there is still a grip area above them.
  • the strips can consist of a webbing coated with plastic, the plastic being extruded around the webbing, for example.
  • the sealing lip can be co-extruded with the plastic.
  • the strips can be cut from a cut
  • Fabrics or a webbing fabric possibly provided with selvedges, exist and are extruded or coated with a thermoplastic material, such as polyurethane or PVC, an adhesion promoter possibly being used as a pre-coating.

Abstract

L'invention concerne une fermeture enroulable pour sachets d'emballage ou similaire, comprenant une extension (1) d'un corps du sachet d'emballage, qui peut être enroulée, ainsi qu'un renforcement destiné à l'extension à l'état enroulé. Au moins deux bandes (2) en matériau flexible sont disposées au niveau de l'extension et parallèlement à ses extrémités, du côté intérieur et/ou extérieur. Ces bandes sont pratiquement congruentes, lorsque l'extension est posée à plat, ou partiellement ou entièrement enroulée, et dépassent latéralement de l'extension.
