Abstract

The clip (6) is shaped from a metal strip with trapezoidal cross-section with the small base line of the trapezoid pointing to the inside of the clip. The small base line is preferably undulating at least in part to form swages on the inward facing surface of the clip. The ends of the clip are bent back outwards in the plane of the clip. The smallest angle of the trapezoid should be no greater than 60 degrees and preferably between 40 and 50 degrees. The clip is preferably made of aluminium.

Description

Die Erfindung betrifft eine aus einem bandförmigen Material gefertigte, U-förmige Verschlussklammer (Clip) zum Verschliessen von Beutein und Schläuchen, insbesondere von Würsten, wie z.B. in DE-PS 26 06 658 oder EU-PS 081 250 beschrieben. Obwohl viele andere Anwendungen in Frage kommen, wird im folgenden der Einfachheit halber nur das Verschliessen von Würsten als Beispiel erwähnt. Dabei muss, trotz der fallweise auftretenden hohen Kräfte - etwa beim Abschliessen von prallen, zum Kochen bestimmten Würsten - eine Verletzung der Verpackung, d.h. des natürlichen oder künstlichen Darmes, vermieden werden. Bei Verwendung der bekannten, einen im wesentlichen rechteckigen Querschnitt aufweisenden Klammern gefährden insbesondere zwei Stellen den Darm: die rechtwinkligen Kanten der auf den Darm gepressten Fläche der Klammer, und die Brauen, respektive Wulste, die an ihren Enden entstehen wenn sie vom Band aus dem sie geformt ist abgeschert wird.The invention relates to a band-shaped Material made, U-shaped locking clip (Clip) for closing prey and hoses, in particular sausages, e.g. in DE-PS 26 06 658 or EU-PS 081 250 described. Although many other uses come into question below is the simplicity just mentioned the sealing of sausages as an example. In spite of the occasional high Powers - for example when closing off plumps, for cooking certain sausages - a violation of the packaging, i.e. of the natural or artificial intestine. When using the known one, essentially endanger rectangular brackets in particular two places the intestine: the right-angled Edges of the surface of the clip pressed onto the intestine, and the brows, or bulges, at their ends arise when it is sheared from the tape from which it is formed becomes.

Um diesem Nachteil zu begegnen, ist die Erfindung wie im Anspruch 1 beschrieben definiert. Dadurch wird unter anderem die Verletzungsgefahr verkleinert, indem einerseits die am Darm anliegenden Innenkanten der Klammer einen stumpfen, wenig einschneidenden Winkel bilden, und andererseits die Braue die beim Abscheren an einer bei fertiger Klammer aussenliegenden Fläche derselben entsteht, gegenüber der Klammerbreite massgeblich zurückversetzt wird.To overcome this disadvantage, the invention is as defined in claim 1. Thereby Among other things, the risk of injury is reduced by on the one hand the inner edges of the Make an obtuse angle that does not cut much, and on the other hand the brow that when sheared off a surface of the same when the clamp is finished arises, significantly set back compared to the bracket width becomes.

Die Erfindung soll nun durch die Beschreibung eines Ausführungsbeispieles und anhand der Zeichnung näher erläutert werden. Es zeigen:

  • Figur 1 einen Längsschnitt durch eine noch offene Klammer, nach ihrem Abtrennen von dem endlosen Band, aus dem sie hergestellt wird.
  • Figuren 2a, 3a Querschnitte durch eine bekannte Klammer längs der Linien II-II, respektive III-III der Figur 1
  • Figuren 2b, 3b Querschnitte durch eine erfindungsgemässe Klammer längs der Linien II-II, respektive III-III der Figur 1.
  • Figur 4 einen Längsschnitt durch eine auf einen Wurstzipfel aufgepresste erfindungsgemässe Klammer, quer zur Längsachse der Wurst.
  • Figur 5 einen Schnitt längs der Linie V-V der Figur 4 durch Klammer und Wurst, parallel zu dessen Längsachse.
    • The invention will now be explained in more detail by the description of an embodiment and with reference to the drawing. Show it:
  • Figure 1 shows a longitudinal section through a still open clip, after its separation from the endless belt from which it is made.
  • Figures 2a, 3a cross sections through a known bracket along the lines II-II, or III-III of Figure 1
  • Figures 2b, 3b cross sections through a clip according to the invention along the lines II-II, or III-III of Figure 1.
  • 4 shows a longitudinal section through a clip according to the invention pressed onto a sausage tip, transverse to the longitudinal axis of the sausage.
  • Figure 5 shows a section along the line VV of Figure 4 by clip and sausage, parallel to its longitudinal axis.

    • Die betrachtete Art von Klammern wird in bekannter, hier nicht näher beschriebenen Weise aus einem endlosen Band geformt. Dieses kann beispielsweise mittels einer Walzrolle aus einem, vorzugsweise aus Aluminium bestehenden Runddraht gewalzt sein, und hat in der Regel ein rechteckiges Profil. Es wird in Längsrichtung so gebogen dass es eine Reihe aneinanderhängender, offener, Klammern bildet von denen jeweils die vorderste durch ein Schneidwerkzeug abgeschert, und danach um die geraffte und/oder verdrehte Wursthaut gepresst wird. Figur 1 zeigt einen Längsschnitt durch diese erste Klammer nachdem sie durch ein, die Schneiden 2 und 3 aufweisendes Werkzeug von der nächsten, nur teilweise und strichpunktiert angedeuteten Klammer 4 abgetrennt wurde. Die Figuren 2a & 2b zeigen den in der Mittelebene II-II der Klammer noch erhaltenen ursprünglichen Querschnitt des Bandes der in Figur 2a eine bekannte, im wesentlichen rechteckige Form aufweist, während Figur 2b den im wesentlichen trapezförmigen Querschnitt einer erfindungsgemässen Klammer zeigt. Beide Querschnitte zeigen in bekannter Weise auf der Oberseite einen zum Teil welligen Verlauf der zur Bildung von Sicken auf der Innenseite der Klammer führt. Figur 2b zeigt eine bevorzugte Ausführungsform der Erfindung bei welcher der Querschnitt im wesentlichen ein gleichschenkliges Trapez mit Basiswinkeln ∝ von 45° bildet. The type of brackets considered is known, way not described here from a endless ribbon shaped. This can be done using, for example a roller from a, preferably made of aluminum Be rolled round wire, and usually has a rectangular profile. It is bent lengthways that there are a number of contiguous, open, Brackets form the first one by Cutting tool sheared, and then around the gathered and / or twisted sausage skin is pressed. Figure 1 shows a longitudinal section through this first bracket after it by a tool with cutting edges 2 and 3 from the next, only partially and indicated by dash-dotted lines Clip 4 was separated. Figures 2a & 2b show the still preserved in the middle plane II-II of the bracket original cross section of the ribbon of the figure 2a a known, substantially rectangular shape has, while Figure 2b the substantially trapezoidal Cross section of a clip according to the invention shows. Both cross sections show in a known manner on the Top of a partially wavy course of the formation leads from beads on the inside of the bracket. Figure 2b shows a preferred embodiment of the invention which the cross section is essentially an isosceles Trapezoid with base angles ∝ of 45 °.

    Die Figuren 3a & 3b zeigen einen Querschnitt der Klammer nach ihrem Abtrennen vom Bande in einer unmittelbar neben der Trennstelle gelegenen Ebene III-III (Fig. 1). Beim Abscheren wird nahe der Schnittebene befindliches Material des Bandes an der mit X bezeichneten Stelle seitwärts gedrängt und das Profil dadurch etwas nach aussen gestaucht, wie an den mit A & B bezeichneten Stellen der Figuren 3a & 3b gezeigt. Wie dem Fachmann bekannt, erzeugt dies bei dem rechteckigen Querschnitt der Figur 2a eine in A nach aussen ragende Braue (Fig. 3a). Bei Verwendung des in Figur 2b gezeigten, erfindungsgemässen Querschnittes ist die in B (Fig. 3b) gezeigte Braue wegen des dort stumpfen Winkels des Profiles weniger scharf. Ausserdem ist sie gegenüber der seitlichen Aussenflanke der Klammer zurückversetzt, was die Verletzungsgefahr eines benachbarten Teiles des Darmes beim Handhaben, insbesonders beim Falten oder Rollen einer Wurstkette, weiter herabsetzt.Figures 3a & 3b show a cross section the clip after it has been severed from the ribbon in one immediately level III-III located next to the separation point (Fig. 1). When shearing, something close to the cutting plane becomes Material of the band on the X marked Place pushed sideways and the profile a little compressed outwards, as on those labeled A & B Locations of Figures 3a & 3b shown. As known to those skilled in the art, creates this with the rectangular cross section of the 2a shows an eyebrow projecting outwards in A (FIG. 3a). When using the according to the invention shown in Figure 2b Cross-section is the brow shown in B (Fig. 3b) because of the obtuse angle of the profile there sharp. In addition, it is opposite the lateral outer flank the parenthesis, reducing the risk of injury of an adjacent part of the intestine Handle, especially when folding or rolling one Sausage chain, further reduced.

    Figur 4 zeigt einen zur Längsachse einer Wurst senkrechten Schnitt durch eine auf einem Zipfel derselben aufgepresste, erfindungsgemässe Klammer 6 deren Enden in üblicher Weise zurückgebogen sind. Es bezeichnet 7 den durch die Klammer hermetisch zusammengepressten Darm, und B die Stelle der (in dieser Darstellung nicht sichtbaren) gerundeten und zurückversetzten Braue B der Figur 3b.Figure 4 shows one to the longitudinal axis of a Sausage vertical cut through one on a corner the same, clamp 6 according to the invention Ends are bent back in the usual way. It denotes 7 the one hermetically compressed by the clamp Gut, and B the place of (not in this illustration visible) rounded and set back brow B der Figure 3b.

    Die Figur 5 zeigt einen Schnitt längs V-V der Figur 4, durch die Klammer 6 und die im Darm 7 eingeschlossenen Füllung 8 einer Wurstkette, in Längsrichtung derselben; dabei sind der besseren Übersicht halber diese Teile nicht massstäblich dargestellt. Aus demselben Grunde wurde das üblicherweise zwischen zwei aufeinanderfolgenden Würsten vorhandene (bei anderen Anwendungen nicht immer existierende) Paar von beabstandeten Klammern durch eine einzige Klammer ersetzt. Figur 5 zeigt deutlich, dass sich die Brauen B hier in grösserer Entfernung des nächstliegenden Teiles des Darmes 7 befinden als dies für einen bekannten, rechteckigen Profil der Fall wäre. Dies ist besonders bei prallen Würsten, deren Umhüllung unmittelbar nach der Klammer fast rechtwinklig radial nach aussen strebt, vorteilhaft. Ausserdem ist aus Figur 5 der Nutzen des (mit D bezeichneten) stumpfen Winkels der inneren Profilkanten ersichtlich. Dieser stumpfe Winkel erlaubt es der Kante dort einen grossen Druck auf die Darmhaut auszuüben, ohne sie zu beschädigen.Figure 5 shows a section along V-V of Figure 4, by the bracket 6 and enclosed in the intestine 7 Filling 8 of a sausage chain, in the longitudinal direction the same; these are for the sake of clarity Parts not shown to scale. For the same reason it was usually between two consecutive Sausages existing (not for other applications always existing) pair of spaced brackets replaced a single bracket. FIG. 5 clearly shows that the brows B are here at a greater distance from the nearest part of the intestine 7 are as this for a known rectangular profile would be the case. This is particularly popular with plump sausages, whose wrapping is immediate radially almost right after the bracket outside strives, advantageous. In addition, from FIG Utilize the obtuse angle (labeled D) of the inner Profile edges visible. This obtuse angle allows there the edge there a great pressure on the intestinal skin exercise without damaging them.
