Opening arrangement

Abstract

An opening arrangement including an openable membrane defined by a weakening line. A pulling device is connected to the membrane by a connecting portion made from a flexible material and includes two arms disposed at an angle to one another. Each arm has a center line. A lower arm is connected via a connection to the membrane adjacent the weakening line and at an angle to a plane defined by the weakening line. The center line of each arm defines a plane which extends substantially parallel with a section of the weakening line located adjacent the connection. The opening arrangement ensures that the necessary force for initiating the tearing off of the membrane is minimized without the risk of unintentional leakage increasing. It also provides an opening arrangement in which a relatively small and compact pulling device is used in order to impart extreme tearing forces on the initiation of the tearing off of the membrane.
