Abstract

La présente invention se rapporte à un couvercle de corps d'emballage qui peut être fabriqué de manière peu onéreuse à l'aide d'une petite quantité de matériau de résine. Ce couvercle (10) est destiné à être fixé à un corps d'emballage de manière à entourer une ouverture de prélèvement d'article ménagée sur une surface du corps d'emballage, ledit corps d'emballage étant utilisé pour recevoir des articles à l'intérieur de celui-ci. Le couvercle (10) est équipé : d'une base de fixation (12) qui est fixée de manière à entourer l'ouverture de prélèvement d'article du corps d'emballage; d'une partie charnière (14) qui est reliée au niveau d'une extrémité à la base de fixation (12) ; et d'une partie couvercle (16) à laquelle l'autre extrémité de la partie charnière (14) est reliée, ce qui permet à la partie couvercle d'être ouverte/fermée par rapport à la base de fixation (12). La base de fixation (12) et la partie couvercle (16) présentent respectivement des parties d'ajustement (24, 32) qui s'adaptent l'une à l'autre lorsque la partie couvercle (16) est fermée. En outre, le couvercle (10), comprenant la base de fixation (12), la partie charnière (14), et la partie couvercle (16), est formé d'un seul tenant par moulage d'un matériau sous forme de feuille de résine synthétique comprenant principalement une résine de polypropylène ou une résine de polyéthylène téréphtalate.
