Abstract

Process for producing a package made of a one-piece blank (2) with a tear-open aid in the form of a tear-open thread (3) provided on the inside, this tear-open aid running in a slightly angled manner in relation to the edges of the blank. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen einer Verpackung, aus einem insbesondere einteiligen Zuschnitt mit einer an der Innenseite vorgesehenen Aufreißhilfe in Form eines Aufreißfadens od.dgl., wobei die Aufreißhilfe gegenüber den Kanten des Zuschnitts geringfügig schräg angeordnet ist (siehe z.B. FR-A-1 216 854).The invention relates to a method for producing a package, from a one-piece blank in particular with a tear-open aid provided on the inside in the form of a tear-open thread or the like, the tear-open aid being arranged slightly obliquely with respect to the edges of the blank (see for example FR A-1 216 854).

Aufreißfäden od dgl. Aufreißhilfen haben sich bei einer Vielzahl von Verpackungen bewährt. Ihre beiden Enden laufen in der Längsnaht zusammen, wodurch ein Ende frei erfaßbar ist. Beim Herstellen dieser Längsnaht, die als Siegelnaht ausgebildet ist, ergeben sich jedoch durch die Verdoppelung der Aufreißhilfe beträchtliche Schwierigkeiten.Tear-off threads or the like. Tear-off aids have proven themselves in a large number of packagings. Both ends converge in the longitudinal seam, whereby one end can be freely grasped. When producing this longitudinal seam, which is designed as a sealed seam, there are considerable difficulties in doubling the tear-open aid.

Der Erfindung liegt die Aufgabe zugrunde, die Aufreißhilfe so anzuordnen, daß eine Materialanhäufung verhindert wird.The invention has for its object to arrange the tear aid so that a build-up of material is prevented.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Aufreißhilfe parallel zur Maschinenlaufrichtung auf einem die Zuschnitte enthaltenden Kartonbogen od.dgl. angebracht wird, während die Zuschnitte geringfügig verdreht zur Maschinenlaufrichtung auf dem Kartonbogen od.dgl. angeordnet werden.This object is achieved in that the tear-open aid or the like parallel to the machine direction on a cardboard sheet containing the blanks. is attached while the blanks are slightly twisted to the machine direction on the cardboard sheet or the like. to be ordered.

Dadurch kommen die beiden Enden der Aufreißhilfe nebeneinander und nicht übereinander zu liegen, so daß keine nachteilige Beeinflussung beim Herstellen der Längssiegelnaht eintritt.As a result, the two ends of the tear-open aid come next to one another and do not lie one above the other, so that there is no adverse influence on the production of the longitudinal sealing seam.

Es hat sich als völlig ausreichend ergeben, wenn erfindungsgemäß die Aufreißhilfe und die Kanten des Zuschnittes mit einem Winkel von etwa 1° gegeneinander verdreht verlaufen.It has been found to be completely sufficient if, according to the invention, the tear-open aid and the edges of the blank are rotated relative to one another at an angle of approximately 1 °.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispieles veranschaulicht. Die Figur zeigt einen Ausschnitt eines Kartonbogens, auf dem zwölf Zuschnitte vorgesehen sind.The invention is illustrated in the drawing using an exemplary embodiment. The figure shows a section of a cardboard sheet on which twelve blanks are provided.

Mit 1 ist ein Kartonbogen bezeichnet, auf dem zwölf gleiche Zuschnitte 2 vorgesehen sind, die zum Herstellen einer Kartonverpackung dienen. Diese Zuschnitte 2 sind gegenüber den Kanten des Kartonbogens 1 um 1° verdreht angeordnet. Über jede Reihe dieser Zuschnitte 2 verläuft ein Aufreißfaden 3, der parallel zu den Außenkanten des Kartonbogens 1 und damit in Maschinenrichtung verläuft. Mit den Kanten bzw. Faltlinien der einzelnen Zuschnitte 2 schließt er dagegen den Winkel von 1° ein.1 designates a cardboard sheet on which twelve identical blanks 2 are provided, which are used to produce cardboard packaging. These blanks 2 are arranged rotated by 1 ° with respect to the edges of the cardboard sheet 1. A tear thread 3 runs over each row of these blanks 2 and runs parallel to the outer edges of the cardboard sheet 1 and thus in the machine direction. With the edges or fold lines of the individual blanks 2, however, it encloses the angle of 1 °.

Claims (2)

  1. Process for the production of a pack from a blank - particularly a single-piece blank - provided on the inside with an aid to facilitate tearing open the pack in the form of, for example, a thread, where the opening aid extends at a slight angle to the edges of the blank, wherein the opening aid is located parallel to the direction of machine movement on a sheet of board or similar material containing the blanks, while the blanks are located on the sheet of board or similar material at a slight angle to the direction of machine movement.
  2. Process according to claim 1, wherein the opening aid extends at a angle of about 1° to the edges of the blank.
