Abstract

L'invention concerne une structure de verrouillage du corps d'un couvercle pour récipient hermétiquement fermé, comprenant un corps de couvercle composé d'une partie de préhension à section transversale concave et d'une partie de bouchage disposée dans la partie intérieure centrale de la partie de préhension, une encoche étant formée dans la surface d'extrémité de la paroi périphérique de la partie de bouchage de manière à s'étendre dans une direction orthogonale par rapport aux filets, une partie de base du col du corps principal du récipient présentant une partie en relief du même diamètre que la périphérie extérieure de la partie de bouchage, la partie en relief étant formée d'une encoche s'étendant de manière orthogonale par rapport aux filets. Lorsque la partie de bouchage et la partie du col du corps principal du récipient sont entièrement engagées l'une dans l'autre par filetage, l'encoche vient en contact avec l'encoche formée dans la surface d'extrémité de la paroi périphérique de la partie de bouchage, et une zone de la partie de préhension est toujours associée à la zone prédéterminée du corps principal du récipient.
