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 are bent outwards and form a connecting web through which the clip can be separated in a strip other parentheses.
  • 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 closed, usually gathered or twisted into a pigtail, 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).
  • closure clips made of band-shaped material are subject to ever increasing demands on locking force, slip resistance and tight closure, which are particularly necessary for the closure of air-impermeable intestines.
  • Different forces act on such a closure clip cf. DE-PS 2 606 658, column 1/2.
  • the locking force and the slip resistance were increased and the locking force was improved in that the band-shaped material in the area of the clip base and the legs on the outer edges was partially folded inwards to form two beads running along these outer edges.
  • These.closing clips have a small radius of the connecting bends between the clip base and clip legs.
  • the braid is not always pressed together 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 closure clip.
  • the use of this closure clip is also only particularly useful if sausages with a relatively large diameter, for example. from 60 mm, should be closed.
  • the invention is therefore based on the object to improve closure clips of the generic type in such a way that they, in particular when using air-impermeable intestines, for. B. from polyvenylidene chloride, polyamide, polyester or from the inside or outside with plastic-coated fiber casings do not slip on the relatively smooth surface of the braid and form a substantially fat and airtight seal and can also be used sensibly with sausages of smaller caliber.
  • the inner radius of the connecting bends between the base of the clip and the leg is at least as follows is large, preferably at least twice as large, as the thickness of the band-shaped material and a preferably inwardly pointing, approximately centrally arranged stiffening bead is provided, which is limited to the area of the clamp base and the connecting bends.
  • the combination of the measures proposed to solve the problem leads to a significantly improved locking clip.
  • the increase in the inner radius of the connecting arches between the clamp base and the leg compared to the conventional closure clamps means that there are no longer any corners between the clamp base and the leg. It is thereby achieved 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.
  • the fact that a rectilinear clip base is retained, especially in the case of closing clips with relatively long legs for closing large-caliber sausages, ensures that they do not turn away in the die after being separated from the clip strip during the closing process.
  • the stiffening bead which is limited to the area of the clip base and the connecting arches, increases the resistance against the clip being bent open and, if it is preferably directed inwards, additionally increases the slip resistance.
  • the bead By restricting the bead to the area of the staple base and the connecting bends to the leg, the deformation resistance of the staple 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 considerably improved properties while maintaining the same material expenditure or it can save material with the same closing force.
  • the locking force could be increased by around 20%, the clip-slip ratio (start of slipping at burst pressure value in kp / mm 2 ) by around 20% and the fat tightness can be improved by about 30%.
  • the sealing clip according to the invention is particularly suitable for sealing 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 are to 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 can be achieved, in particular in the case of sausages of smaller caliber, that is to say less than about 50 mm in diameter, 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 when cutting and closing in the die.
  • known longitudinal grooves were provided on the inner surface of the clip, preferably in the region of the legs into which the inner bead does not extend, in order to increase the slip resistance compared to a closure clip made of smooth material.
  • 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 arches 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 arches 4, 5 is an inwardly directed stiffening bead 6, which extends approximately to the transition of the connecting arches 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 of 7.8.
  • the legs 2, 3 extend to the bending points of the leg ends 9, 10 bent outwards, with U-shaped impressions 11, 12 being attached to their underside.
