Definitions

  • the invention relates to a bag closure for an opening created by tearing or cutting open a packaging bag, comprising a collar to be fitted in the opening of the packaging bag and a closure element.
  • a bag closure for example, in the sales packaging according to DE A1 43 36 377, the lower end of a bag-shaped container has an opening in or on which a receiving ring is inserted or formed, and the opening can be securely closed by a closing element.
  • EP A1 0 401 494 relates to a sack for waste disposal, consisting of a flexible bag part which is closed at the bottom, a rigid sack collar which surrounds the upper end of the flexible bag part and is firmly connected to it, and a lid with which the Sealing the bag part in the area of the sack collar.
  • DE A1 31 49 540 discloses a reclosable zipper for packaging bags in which at least one layer consists of sealable material. The closure consists of an annular collar attached to the bag by sealing and a lid for closing the opening in the collar.
  • All of the bag closures mentioned are either designed for a certain size of a bag or sack, or are inextricably linked to it.
  • the bag closure according to the invention has the following advantages over the known closures: it can be easily attached after opening or cutting open any packaging bag - within a certain size range. After the packaging bag has been completely emptied, the bag closure can be easily removed and reused.
  • the bag closure is made of plastic. As a result, it can be easily and inexpensively manufactured in one piece, for example by means of an injection molding process.
  • the closure element can be a cover connected to the collar by a film hinge.
  • a holding pin is arranged on the lid, which engages in an opening in the lid when it is closed, which is provided in a tab arranged on the collar.
  • the hinge can also be designed as a snap hinge, or a hook can be provided on the cover, which, when the cover is closed, engages over an outwardly projecting nose on the collar.
  • the means for changing the diameter of the collar consist, for example, of an axial slot present in the collar, which allows the collar to be radially deformed in the manner of a spring ring.
  • the holding elements can consist of fastening tabs on which fixing pins are arranged such that they fit into receiving openings arranged in the collar when the fastening tabs are bent. These fastening tabs can be attached to the collar by means of film hinges.
  • the holding elements can consist of circumferential grooves spaced apart from one another, into which an elastic ring, for example a rubber ring, can be inserted with the interposition of the packaging bag.
  • a support bracket can be provided in all embodiments, which is used to carry the bag closure together with the bag attached to it.
  • the bag closure 1 shown in perspective in FIG. 1 can consist of a plastic and can be produced in one piece, for example by injection molding. It consists of a collar 2 with which a cover 3 is articulated by means of a cover hinge 4.
  • the lid hinge 4 can be designed in the form of a film hinge.
  • the collar 2 has an axial slot 5 on its side opposite the cover 3.
  • the wall thickness of the collar is reduced.
  • the reductions in the wall thickness are designed such that the outer diameter of the collar is reduced in an upper region 6 and the inner diameter is enlarged in a lower region 7 axially adjacent to this. This creates a displacement between regions 6 and 7.
  • regions 8 and 9 are offset in a similar manner, but here the inner diameter of the collar is enlarged in the upper region 8 and the outer diameter is reduced in the lower region 9 .
  • the collar has a slot 11 which runs in the circumferential direction and separates the regions 8 and 9 into two tongues 12, 13, as can be seen particularly clearly in FIG. 5. If the collar is now compressed in the radial direction in order to insert the bag closure into an opened bag, the tongue 12 slides over the outside of the area 6 and the tongue 13 slides along the inside of the area 7. Bevels 14 at the ends of the tongues help to guide the tongues onto the corresponding sides of the areas 6, 7. Thus, when the collar is pressed together, the locations on both sides of the slot 5 are intertwined, as it were, and it is prevented that they move away from one another in the radial or axial direction. This makes it easier to insert the bag closure into the bag.
  • the collar When the collar inserted into the open end of a bag is released, it springs back outwards and lies against the inside of the bag opening. In this way, the bag closure automatically adapts to packaging bags of different sizes.
  • the collar has fastening tabs 15 distributed around its circumference. The latter are, as shown in Fig. 4, connected to the collar by means of a film hinge 16 and have a fixing pin 17 pointing downward. If the fastening tab is folded down around the hinge 16, the fixing pin 17 pierces the material of the packaging bag and penetrates into a receiving opening 18 arranged in the collar. So that the fixing pin remains securely in the receiving opening, it is slightly undercut, as shown in particular in FIG. 4.
  • the fixing pin could be of blunt design such that it does not pierce the bag material, but rather pulls it into the receiving opening. If the diameter of the receiving opening is dimensioned accordingly, the fixing pin is clamped in the receiving opening with the bag material surrounding it, so that an undercut design of the fixing pin can be dispensed with under certain circumstances.
  • the lid 3 In order to hold the lid 3 in its closed position, it has a holding pin 19 in the region of the hinge 4, which fits into an opening 20 which is arranged in a tab 21 projecting from the collar.
  • the hinge 4 of the cover 3 could also be designed as a snap hinge.
  • the lid has a grip strip 22 on its edge opposite the hinge.
  • FIGS. 7 and 8 show further exemplary embodiments of the bag closure.
  • the same reference numerals with an added '(Fig. 7) or' '(Fig. 8) are used.
  • These two embodiments also have a collar 2 'or 2' 'to which a cover 3' or 3 '' is connected via a hinge 4 ', 4' '.
  • this collar 2 ', 2' 'does not have a slot 5, but rather forms a closed ring.
  • the hinge 4 ' is designed as a snap hinge.
  • the collar 2 ' is conical in an area 27.
  • it can simply be pushed into the packaging bag 23 until its opening edge 24 abuts the outer surface of the collar 2 '.
  • the collar 2 ' has a plurality of circumferential grooves 25 arranged at an axial distance from one another.
  • the exemplary embodiment according to FIG. 8 also has a conical collar 2 ′′.
  • the fastening of the closure in the bag opening takes place here in the same way as in the examples shown in FIGS. 1 to 6, that is to say by means of fastening tabs 15 and fixing pins 17.
  • the fastening tabs here are somewhat longer so that they can also detect the edge of a bag opening into which the bag closure can only be partially inserted due to the conicity of the collar 2 ′′.
  • only the receiving openings 18 '' are visible.
  • a hook 28 is injection molded onto the cover in this embodiment, which overlaps an outwardly projecting nose 30 on the collar 2 ′′ when the cover is closed.
  • the example according to FIG. 8 also has a carrying bracket 30 which serves to carry the bag closure together with the bag attached to it.
  • a carrying bracket 30 which serves to carry the bag closure together with the bag attached to it.
  • Such a bracket can be provided in all of the exemplary embodiments shown.
  • the bag closure and in particular the collar is shown circular in FIGS. 1, 2 and 6, the invention is not restricted to this. Rather, the collar, and of course the lid, can have any shape and, for example, the shape of a polygon with three or more corners.
