ABSTRACT:
A packaging, preferably a bag of a flexible material, provided with an opening device for facilitating opening of the packaging. The opening device comprises a plate being more brittle and rigid than the packaging material and provided with a transverse weakened line formed of a groove-like portion of reduced plate thickness dividing the member into two halves, each of which may gripped between the thumb and forefinger of a person. The opening device is dimensioned in such a manner in the area of the weakened line that without any difficulty a person can break the device along said line by rotating the two halves towards each other about said line. In close proximity of the groove, a perforation edge is formed in at least one of the halves. The plate member is attached to the packaging with the sharp edge facing the interior of the packaging.
