IMPROVEMENTS IN AND RELATING TO THE OPENING OF CONTAINERS |
摘要 |
<p>Containers made of flexible material often have opening arrangements in the form of a tear strip for opening an outlet aperture. The tear strip constitutes a part of the container wall and is limited by a weakening line. To facilitate initiation of the tear-open operation a short length of the weakened line has the form of a cut or cuts extending fully through the material. Two or more cuts may form a lug or projection, and if located at a fold line of the container blank the lug or projection may be arranged to automatically extend outwards from the finished container.</p> |
