A shirred tubular food casing packed into a tubular netting This invention relates to a shirred, tubular food casing wrapped in tubular netting which may be used without difficuIties particularly on sausage filling machines.
It has already been proposed (cf. US Patent No.
3,639,130) to pack shirred, tubular casings in tubuIar netting having a cord or clip closure for the purpose of transport and storage in water. In the mechanised produc-tion of sausage, a shirred and packed food casing such as this is generally pushed onto the filling nozzle of the sausage-filling machine and, following removal of the closure from the tubular netting, is filled in portions. Difficulties can arise when the packed tubular casing is pushed onto -the filling nozzle because the net wrapping radially compresses the ends of the shirred food casing. This can be counteracted by using a supporting disc, which has to correspond to the dimensions of the filling nozzle for the bore and to the dimensions of the shirred casing with regard to its external diameter;
the supporting disc is introduced into the net wrapping at the ends of the shirred food casing and by guiding the holding force of the net wrapping substantially in the direction of its axis so that deformation is a~oided at the ends and the shirred food casing is safely fixed on the filling nozzle in the axial direction.
The disadvantage of this kind of packaging is that a number of supporting discs with the appropriate dimensions has to be kept available and further in the fact that the net wrapping has to be removed after the casing has been opened and fitted onto the filling nozzle.
~ ~51~6 Accordingly, there is a need to modify the ~nown tubular net wrapping for shirred tubuIar food casings so that no diffuclties are involved in fitting the packed tubular casing onto the filling nozzIe and to fix one and the same tubular casing axially to differently dimentioned filling nozzles.
Accordingly the present invention relates to a shirred food casing packed into a tubuIar net wherein at least at one end of the shirred food casing a flexible ring is situated within the tubuIar net.
At the other end - opposite to the flexible ring - the wrapping net may be closed in known manner with a clip after the tubular net, guided from one end of the shirred food casing on the outside of the casing to the other end and through the interior o the casing back to the fixed end of the food casing, has been tightened by pulling at both ends to compress the food casing and after both ends of the net have been cut to the same length. In one preferred embodiment, an opening aid is provided at this opening end before it is closed by the clip, consisting of a hol:Low disc with a centrally situated annular disc which is provided with a cutting edge. The net pac~ed, shirred food casing is then fitted onto the filling nozzle at its open end where the flexible ring is situated. Th~reby the filling nozæle comes up against the centrally situated annular cutting edge which presses onto the net, cuts it and hence automaticall~ opens it.
In another preferred embodiment, the wrapping net is not guided through the hollow interior of the shirred tubular food casing, instead it is guided from the first end of the shirred tubular food casing along the outside ~5~16 to the second end where the flexible ring is situated, looped around this flexible ring and guided back along the outside of the shirred food casing to the first end.
The two ends of the net are tightened in ~nown manner, so that it is also possible to adjust the flexible ring around which the net is looped to a required diameter, and are then closed in the manner described above. After the casing has been fitted onto the filling nozzIe, for which purpose the ring generally has to be 10 stretched somewhat further, and after the net has been opened, so that the ring is relaxed to a slight extent, the ring firmly applies around the filling nozzle and thus the wrapping net is firmly fixed around the filling nozzle. The food casing may be readily withdrawn 15 from the wrapping net and filled without the net ha~ing to be removed. After the packed food casing has been used, the net wrapping is simply withdrawn with the ring from the filling nozzle.
In another preferred embodiment, the shirred 20 tubular food casing is clamped between two flexible rings, preferably rubber rings, around which the wrapping net is looped in the manner described above. If the wrap~
ping net, in the form of a double net, is only guided along the outside of th shirred food casing, the ends of the net are preferably not closed by means of a clip at one end of the food casing. Instead the second end of the net, after being wrapped around the second flexible ring, is guided back along the outside of the food casing approximately to the centre thereof where it is welded to the first end of the wrapping net.
The shirred food casing (stick) packed into a tubular net with at least one flexible ring situated at one end in accordance with the invention are preferably produced as follows:
The shirred ~ood casing is removed in the form of a hollow stick from a standard commercial shirring machine and introduced into a tubular net of suitable length. At one end, the flexible ring is threaded on over the tubular net and moved right up to the shirred tubuIar 10 casing. The tubular net is then pushed over both the ring and the shirred tubular casing so that the shirred tubular casing is packed into a double net.
The new-packed food casing may then be closed in known manner by means of a clip.
~5 In addition, it is also possible to introduce the net-packed food casing into a known holding and sealing machine. In this case, too, a flexi~le ring is again initially threaded on over the e~posed end of the net wrapping, pushed up to the shirred tu~ular food casing 20 and the second end of the tubular net is also pushed over the ring and the food casinq. The second side of the holding and sealing machine i.s then applied and the two inverted ends of the net are welded in known manner.
An~ superfluous ends are then cut off.
The flexible rings used are preferably rubber rings which also have a circular cross section of from 2 to ~ mm.
The hollow disc and annular disc comprising a cutting edge which are used as an aid to opening axe prefera~ly made of a thermoplastic plastic, such as 30 polyamide, ABS or polystyrene.
1 ~ 6 ~ 6 The wrapping net is normally a polyethylene net and the food casing preferably consists of cellulose regenerate which has to be moistened before filling.
Several embodiments of the food casing with the improved wrapping are described in detail in the following with reference to the accompanying drawings.
Figure 1 shows a shirred food casing 2 which is packed into a double net 1 of polyethylene and which is provided at one end with a rubber ring 3 and at its other end with an opening aid consisting of a hollow disc 4 and an annular disc 5 with a cutting edge. The wrapping net is closed at this end by means of a clip 6.
Figure 2 shows a shirred food casing 22 which is packed into a double net 21. At both ends of the food casing, there are situated rubber rings 23 around which the wrapping net was guided. The wrapping net 21 which only lies on the outside of the food casing 22 is externally welded at 7, i.e. approximately at the centre of the food casing 22.
Figure 3 is a modification of the arrangement in Figure 2 ln which the end of the food casing 32 is closed by means of a clip 36. Through this measure, the casing is open at one end for fitting onto the filling nozzle, whereas in the embodiment shown in Figure 2 it may be fitted on at either end.
