Definitions

  • the invention relates to a U-shaped closure clip made of band-shaped material for tubes and bags, the clip consisting of a clip base and two legs and the leg ends of the clip being bent outwards and forming a connecting web through which the clip can be separated in a strip with others Brackets are connected and the inner radius of the connecting arches between the bottom of the bracket and the legs is at least as large as the thickness of the band-shaped material.
  • the packaging braid of a bag or tube is closed with these clips in such a way that first a clip with its clip base is inserted into a suitable die with the legs pointing upwards, and then the packaging sleeve to be sealed, usually gathered or twisted into a braid, is placed in the clip is what a stamp approaches the die from above and the clip separates from the strip and closes (DE-PS 1 078 495, 1 761 616 and 2 606 658).
  • the braid is not always pressed together sufficiently tightly at these points in the closed state, as a result of which, in certain cases, capillary formation can occur at these points, which in turn can lead to leaks and thus to grease escaping or air entry at the closing clip.
  • this locking clip only makes sense if sausages with a relatively large diameter, for example from 60 mm, are to be sealed.
  • the invention is therefore based on the object of improving closure clips of the generic type in such a way that, in particular when using air-impermeable casings, e.g. made of polyvenylidene chloride, polyamide, polyester or fiber casings coated with plastic on the inside or outside, do not slip on the relatively smooth surface of the braid and form an essentially fat and airtight seal and can also be used sensibly with sausages of smaller caliber.
  • air-impermeable casings e.g. made of polyvenylidene chloride, polyamide, polyester or fiber casings coated with plastic on the inside or outside, do not slip on the relatively smooth surface of the braid and form an essentially fat and airtight seal and can also be used sensibly with sausages of smaller caliber.
  • a preferably inwardly pointing, approximately centrally arranged stiffening piece is provided, which is limited to the area of the clip base and the connecting bends.
  • the inner radius of the connecting arches between the clamp base and the leg should preferably be at least twice as large as the thickness of the band-shaped material.
  • the combination of the measures proposed to solve the task leads to a significantly improved locking clip.
  • the increase in the inner radius of the connecting bends between the clip base and the leg compared to the conventional closing clips means that there are no longer any corners between the clip base and the leg. This ensures that the sausage braid completely fills the closed clip so that it is firmly pressed together over its entire surface. This avoids the risk of capillary formation and essentially eliminates grease leakage or air entry at the locking clip.
  • a straight clamp base is retained means that, particularly with closure clips with relatively long legs for closing large-caliber sausages, it is achieved that, after being separated from the clip strip, they do not turn away in the die during the closing process.
  • the stiffening bead which is limited to the area of the clip base and the connecting arches, increases the resistance to bending the closing clip and, if it is preferably directed inwards, additionally increases the slip resistance. By restricting the bead to the area of the clip base and the connecting bends to the leg, the deformation resistance of the clip legs is kept as low as possible in the upper area during the closing process in order to enable a machine-friendly and intestinal low closing force.
  • the measures according to the invention achieve a closure clip with significantly improved properties while maintaining the same material expenditure, or material can be saved with the closure force remaining the same.
  • the locking force could be increased by around 20%
  • the clip-slip ratio start of slipping at a burst pressure value in kp / mm 2
  • the fat tightness can be improved by about 30%.
  • the closure clip according to the invention is particularly suitable for closing cooked sausages treated in an autoclave, in which the internal pressure of the sausage rises sharply, of cooked sausages that are cooked or scalded and of sausages that should have a long shelf life.
  • a special use is also the sealing of externally coated fiber casings, the coating of which is so smooth that closures can easily slip off during cooking due to the filling pressure or increasing internal pressure.
  • the object on which the invention is based in particular in the case of sausages of smaller caliber, that is to say less than about 50 mm in diameter, can be achieved by a modification of the invention in such a way that the connecting bends form a round arch with a common radius with the clamp base. Because of the short legs, there is no risk that the locking clip will turn away in the die when it is cut and closed.
  • leg ends bent outwards should have the known U-shaped embossing at the bending point with the clip leg on the underside in order to ensure the associated advantages.
  • FIG. 1 shows a closure clip with clip base 1, separated from the clip strip, with which the legs 2, 3 are connected via connecting bends 4, 5.
  • the two connecting arches 4, 5 have radii R4 and R5 which are greater than the thickness of the band-shaped material of the clip.
  • Extending over the clamp base 1 and the connecting bends 4, 5 is an inwardly directed connecting bead 6 which extends approximately to the transition of the connecting bends 4, 5 and thus at the center of the radii R4 and R5 and into the straight part of the legs 2 , 3 leak in the area 7, 8.
  • the legs 2, 3 extend to the bending points of the leg ends 9, 10 which are bent outwards, with U-shaped impressions 11, 12 being attached to their underside.
  • FIG. 2 shows a closing clip separated from the clip strip, whereby — in contrast to FIG. 1 — the connecting bends 4, 5 form an arch with a common radius R with the clip base 1, so that a common center point 13 is created.
  • FIG. 3 shows a clip strip made of clips according to FIG. 1, wherein grooves 14, 15 (FIG. 5) running through in the outer edges of the band-shaped material in the area of the stiffening bead 6 are additionally embossed.
  • FIG. 4 shows a clip according to FIG. 3, which is closed around a packaging braid 16. It can be seen that the sausage braid 16 completely fills the closed clip in the area of the connecting sheets 4, 5, so that it is firmly pressed together over its entire surface.
  • FIG. 5 shows a partial section AA through the butt seam 17, the sausage braid 16 and the clip base 1.
  • the grooves 14, 15 stamped into the outside edge of the clip form the beads 20, 21 on the inside of the clip and the beads 22 on the outside. 23.
