Definitions

  • the present invention relates to packaging made of film-like material which has particular advantages in the packaging of non-free-flowing materials.
  • Such materials are e.g. B. more or less irregularly shaped objects, such as machine parts, tools and boxes, or fabrics that matted under pressure, such as woven fibers and peat.
  • the packaging firmly attached to these goods, e.g. B. after the goods have been brought into the packaging by means of a press or because the film-like packaging has shrunk after wrapping the object to be packed, it is possible without destroying the packaging, e.g. B. by cutting, not possible or only with a lot of time to unpack the goods.
  • the packaging is therefore usually unusable for further uses.
  • US-A4294360 relates to a packaging for sterile goods, which has a removal opening created by tearing open a predetermined breaking point in the form of a fold, so that the contents of the packaging can be removed through them without being contaminated by impurities. Such packaging cannot be reused after the contents have been removed.
  • the present invention has set itself the goal of making packaging for materials described at the outset reusable. For this purpose, it provides for a fold running across the filling and removal opening in the packaging and this fold being attached to the two edges of the folds by means of a connection which is fastened to both fold parts and does not open during the filling process, but can be separated in the event of removal Keep the inserted fold closed.
  • the connection between the two fold parts is separated, the packaging thereby widens by the width of the film wrapped in the fold, so that the packaged goods can be easily removed.
  • the packaging as such is preserved and can e.g. B. can still be used as a container for collecting waste, such as garbage, or as a protective cover.
  • a thread running between the two fold parts and adhering to them can serve as a connection of the two fold parts preventing the fold from opening. It is also possible in some cases, the two fold parts by a seam, for. B. a chain seam, or by welding, e.g. B. to hold a spot weld together.
  • connection is expediently formed by a strip, in particular made of the same material as the rest of the packaging, which is attached to both fold parts by sewing, gluing or welding. He can e.g. B. with a knife or scissors between the two fold parts.
  • connection is facilitated in that it is perforated or has a toothed separating strip or a tear tape or a tear thread.
  • the opening of the fold can also be made possible by the fact that the connection is welded or glued in a punctiform manner and is therefore easy to tear off.
  • a releasable adhesive strip can serve as a connection, which can also be easily removed.
  • the strip which connects the two fold sides can be applied both to the inner (lower) and preferably to the outer (upper) fold sides.
  • the fold itself can be a single or a double fold.
  • the film-shaped packaging can e.g. B. consist of paper.
  • packaging made of plastic films is preferred. Both single-layer and multilayer films are possible.
  • the fold is expediently formed on the film tube and provided with the connection before the individual packaging units are produced by cutting up the tube. If the tube or a bag is formed from a film web, the fold can be placed on one side of the web and the other side of the web can be attached to both fold parts so that this side of the web itself forms the connection between the two fold parts.
  • Packaging in particular sack-shaped packaging with side gussets extending from the opening end of the packaging are e.g. B. known from DE-A-29 47 784.
  • the folds serve there to give the sack an essentially rectangular cross-sectional shape when filled. Accordingly, the side parts of the folds are not held together there by means of a connection.
  • DE-OS 30 43 491 the abutting inner sides of a gusset of a gusseted tube, which is to be used for the production of gusseted bags, temporarily with one another, for. B. connected point by point with a pressure sensitive adhesive in order to be able to transport and possibly separate the unfilled hoses without interference.
  • the temporary connection of the two fold sides opens at the latest when the gusseted tube is filled.
  • the fold serves to enlarge the size of the filled bag before it is emptied.
  • the connection is accordingly fastened to both fold parts so that it does not come loose during the filling of the packaging, but can be separated after the packaging has been used as intended.
  • the inner layer even when filled, a compensation has fold, while the outer layer does not form a fold.
  • This is intended to tear the inner layer, e.g. B. due to the stress when filling the bags or because of different stretching behavior of the different layers forming the packaging can be avoided.
  • the fold of the inner layer is held together by the outer layer in this packaging; To facilitate the removal of the contents, the generally firmer outer layer would have to be cut open.
  • the inner layer of the packaging would be reusable, but it is less useful for the purposes mentioned at the beginning. Therefore, according to the invention, in the case of a multi-layer packaging, the fold is formed by all layers of the packaging, including the outer layer, and the connection that keeps the fold closed is attached in particular to the outer layer.
  • FIG. 1 shows a package in view
  • Fig. 2 as a section along the line a-b the fold kept closed according to the invention
  • Fig. 3 shows the fold after the connection has been broken.
  • FIGS. 4 and 5 Other forms of connections or folds are shown in FIGS. 4 and 5.
  • Fig. 6 finally, a fold is shown, the z. B. after folding a sheet of film around the goods to be packaged or in the manufacture of a bag from a sheet of film.
  • the film-shaped packaging 1 in the form of a bag is closed at the end 2, for. B. by welding or gluing. From this opening side, the band 3 covering both sides of the fold 4 extends to the bottom of the sack. Both long sides of the tape are glued or welded to the side parts of the fold at 5 and 6, so that the fold cannot open. Only after the tape has been cut (Fig. 3) does the fold open and allow the packaged goods to be removed.
  • connection 3 is formed by a chain seam
  • FIG. 5 the fold is glued together as a connection 3 with a tear strip.
  • FIGS. 2, 3, 4 and 6, which show double folds a single fold is shown here. With this connection, too, the fold can be placed as a double fold, just as it can be a single fold in the other cases.
  • FIGS. 1 to 5 While the pleats is shown in particular in tubular bags in FIGS. 1 to 5, the possibility of attaching of the fold is shown in a laid around the packaging film web in Fig. 6.
  • the fold is placed at one end 1 'of the packaging film.
  • the other end 1 "of the packaging film is pulled over the fold and connected to both side parts of the fold.
  • the fold opens, for example, after cutting or separating the part of the film which serves as connection 3 'between the two fold parts the attachment 6 as a spot weld and the film 1 "z. B. survive a finger's width, you can easily open the fold by tearing the spot weld without tools.
