Definitions

  • the invention relates to a U-shaped, plastically deformable closure clip for closing tubular or bag-like packaging, in particular sausage casings made of natural casing filled with pasty filling material, in which two clip legs connect to a clip bottom on both sides.
  • the free ends of the closed locking clip butt against one another or are guided parallel to one another so that they overlap laterally.
  • dies which have a single sliding groove.
  • the sliding groove is usually semicircular and has an entry point for the two free leg ends of the open closure clip at the two ends of the semicircle.
  • the die and the stamp with the open closing clip and the bag braid inserted therein are moved towards each other for closing.
  • the two free leg ends of the locking clip enter the sliding groove at the two entry points thereof and are guided by the sliding groove in the course of the further movement with simultaneous plastic deformation of the locking clip until they collide.
  • the locking clip is then deformed in such a way that the transition regions between the base of the clip and the two legs are compressed and at the same time dodge laterally, so that the locking clip finally has a flattened shape.
  • compressing the closure clip after the free leg ends collide requires high forces, which on the one hand leads to greater machine wear and on the other hand also to a higher stress on the material of the packaging sleeve to be closed.
  • this type of sealing with a die with a single sliding groove is preferred for packaging casings made of natural casings.
  • the intestine may only be clamped in the middle area of the closing clip between the clip bottom and the joint of the clip legs.
  • the intestine must be able to escape into the free spaces created by lateral expansion of the transition areas between the staple leg and the staple floor. The risk that the natural casing is pinched and damaged between the abutting leg ends during the closing process is accepted.
  • both slide grooves have a semicircular shape and run parallel to one another, the center plane between the two slide grooves being slightly inclined relative to the main plane of the closure clip, so that each slide groove has an entry point which lies in the main plane of the closure chamber.
  • closure As a result, the two free ends of the closure clip slide past one another when being closed, so that after the closure they overlap laterally and lie parallel to one another.
  • This type of closure is preferably used for packaging whose cover material is made of plastic. The resulting closure is particularly tight because the end of the packaging envelope is clamped in a labyrinthine manner by the closure.
  • this closure is not suitable for packaging casings made of natural casings because, in contrast to those with butt joint ends of the staple, there is no free space due to laterally diverging transition areas between the staple floor and the limb limbs into which the natural casing can escape.
  • U-shaped locking clips which have an increased moment of resistance against the opening of the closed clip. This is particularly necessary for artificial casings, as they are airtight and not very elastic, so that e.g. when a sausage is cooked, this creates a large internal pressure which the closed locking clip must withstand.
  • natural casings are so elastic that they increase their diameter when cooking, without building up a large internal pressure, and contract again after cooking. Only small forces are exerted on the locking clip.
  • the invention is therefore based on the object of specifying a closure which is also particularly suitable for natural casings and which largely avoids the disadvantages of the prior art.
  • the solution to this problem consists according to the invention in a closure clip of the type mentioned, which is weakened in the two transition areas from the bottom of the clip to the clip legs.
  • a closure clip of the type mentioned, which is weakened in the two transition areas from the bottom of the clip to the clip legs.
  • Such a closure clip can not only be closed with considerably lower forces, but depending on the shape of the weakening results in a denser and more secure closure than known closure clips.
  • It has also been found that even sensitive natural casings can be securely closed with this locking clip using a die with two sliding grooves.
  • the weakening of the transitional areas they also deflect to the outside and give the lateral spaces required for closing natural casings, into which the natural casing can move if the closure clip is closed with a die with two sliding grooves.
  • the size of the lateral free spaces can be predetermined by the length of the weakened transition areas.
  • the closing clip preferably has a cross-sectional shape which facilitates the deformation in the two transition regions from the clip base to the clip legs.
  • the two transition regions are flattened perpendicular to the main plane of the closure clip.
  • Closure clip main plane is understood to mean the plane in which the center lines of the clip legs and the clip bottom of the open clip clip run. Due to the flattening of the closure clip perpendicular to the main closure clip plane, the closure clip in the closure clip main plane is easier to deform, while a deformation transverse to the closure clip main plane is made more difficult.
  • closure clip In an alternative embodiment of the closure clip, it has a smaller cross-sectional area in the two transition areas from the clip base to the clip legs compared to the areas adjacent to the transition areas. This also leads to a weakening of the closure clip in the transition areas.
  • the weakening of the closure clip in the transition areas can be uniform. In an alternative embodiment of the closure clip, the weakening is greatest in the transition areas where the transition areas connect to the bottom of the clip. From there, the weakening of the transition areas down to the clamp legs decreases steadily. With such a closure clip, the one that arises when the clip is closed Free space can be easily influenced by slightly changing the closing pressure.
  • the weakening of the closure clip is preferably caused by an embossing in the transition areas. Such an embossing can easily be introduced in the manufacture of the closure clip.
  • FIG. 2 shows the closure clip from FIG. 1 after regular closure
  • FIG. 3 shows the closure clip from FIG. 1 after closing with increased closing forces
  • Fig. 4 shows a closure clip according to the invention with weakened
  • FIG. 5 shows the closure clip from FIG. 4 in the closed state
  • FIG. 6 shows a closure clip according to the invention, in which the weakened transition regions are longer than in the closure clip from FIG. 4;
  • FIG. 7 the closure clip from FIG. 6 in the closed state
  • Fig. 8 a closure clip with increasing towards the bottom of the clip
  • Fig. 1 shows a closure clip 1 0 known from the prior art with a clip base 1 2 and two clip legs 1 4.
  • the clip base 1 2 merges into the clip legs 1 4 in the form of two connecting bends 1 6.
  • the locking clip 10 shown has a straight clip bottom section 1 8 between the two connecting bends 16, depending on how the two Connection arches 1 6 are formed, the straight bracket base section 1 8 can also be omitted entirely, so that the two connection arches merge directly into one another.
  • the last-mentioned closure clip shape is intended for closure clips, which take on an approximately circular shape after closure, while the closure clip shape shown results in an oval closure clip after closure, as shown in FIG. 2.
  • Fig. 2 shows the closure clip 1 0 from Fig. 1 after it has been closed so far that its legs 1 4 run parallel to the straight clip bottom section 1 8 and overlap laterally parallel to each other.
  • the closed closure clip 1 0 includes a free space 20, which is just dimensioned so that the packaging material located in the free space is slightly compressed, so that a tight seal results without the packaging envelope being destroyed.
  • Closure clips which in the closed state have a larger free space for closing a larger caliber (this is the cross-sectional area of the packaging sleeve material gathered up into a braid), generally have longer clip legs than the closure clip 10 shown in FIGS. 1 and 2.
  • closure clip 1 0 shown in FIGS. 1 and 2 If the closure clip 1 0 shown in FIGS. 1 and 2 is to be used for closing smaller calibres, it must be deformed under increased closing force to such an extent that its legs 14 no longer run parallel to the straight clip bottom section 1 8, but instead buckle further, so as shown in Fig. 3. Only by much higher sealing forces would the closure clip 10 be compressed in the area of the connecting bends 16 so that the free space 20 becomes even smaller and the clip legs 14 lie on the packaging material.
  • the closure clip 1 0 in FIGS. 1 to 3 has the same cross section everywhere and can be easily produced by bending a round wire section.
  • Fig. 4 shows a closure clip 1 0 'according to the invention which, like the closure clip 1 0 from FIGS. 1 to 3, has a clip base 1 2' and two clip legs 1 4 'adjoining it on both sides.
  • the closing clip 10 is somewhat weakened in cross section in the transition regions 22' between the clip base 1 2 'and the respective clip leg 1 4' by an indentation 24 '.
  • the indentation is 24 ' for example, only a few tenths of a millimeter deep.
  • the free space 20 'enclosed by the closed locking clip 10' is almost zero. 4 and 5, very thin casings, such as, for example, pig's casing casings, can therefore be securely closed without damaging the sensitive intestine.
  • an air pressure of approximately 2 bar is sufficient, while compressing the closing clip requires, for example, an air pressure of 5 to 7 bar.
  • the closing force can easily be set which leads to the desired degree of compression of the closing chamber. Due to the large range, the closing force is set between 2 bar and 7 bar very possible.
