Patent

CA 2224903

Plastic bucket provided with a lid, the bucket having a single upper edge, a circumferential rib, and a depending edge connecting to the circumferential rib, the circumferential rib and the depending edge having such a profile that in sealed condition gripping the free lower edge of the lid is impossible. After removal of the sealing lip, gripping the free lower edge of the lid at the sealing position is possible in that the shape of the circumferential rib, and the depending edge connecting thereto, at the sealing position deviates from the shape thereof at the other circumferential positions, this deviating shape, however, in each case being such that the circumferential rib, throughout the circumference and hence also at the sealing position, extends adjacent to the upper edge of the bucket, so that the stiffness of the bucket is substantially the same throughout the circumference thereof.

Seau en plastique muni d'un couvercle. Le seau comporte un seul rebord supérieur, une nervure périphérique et un rebord rattaché à la nervure périphérique. La nervure périphérique et le rebord qui s'y rattache présentent un profil faisant en sorte que lorsque le seau est en position scellée, il est impossible d'avoir prise sur le rebord libre du couvercle. Lorsque la lèvre d'étanchéité est retirée, il est possible d'avoir prise sur le rebord inférieur libre du couvercle lorsqu'il est en position scellée parce que la forme de la nervure périphérique et du bord qui s'y rattache, en position scellée, ne correspond pas à sa forme dans les autres positions circonférentielles. La position déviée, dans chacun des cas, est telle que la nervure périphérique, sur toute la circonférence et donc en position scellée, se prolonge à proximité du rebord supérieur du seau, de sorte que la rigidité du seau est généralement la même sur toute la circonférence.
