Abstract

Des aspects de la divulgation se rapportent à un emballage (P ; P' ; P"), un plateau (90) et un couvercle (190 ; 290 ; 390) destinés à emballer un ou plusieurs articles (B) et une ébauche (10, 110 ; 210 ; 310) destinée à former ces derniers. Une combinaison d'une ébauche de plateau (10) et d'une ébauche de couvercle (110 ; 210 ; 310) est décrite. L'ébauche de couvercle (110 ; 210 ; 310) comprend une paire de rabats pliables (118, 120 ; 214, 216 ; 314, 316) raccordés de manière articulée à des extrémités ou côtés opposé(e)s respectifs/ves d'un panneau supérieur (114 ; 212, 312A/312B) de l'ébauche de couvercle. Chacun des rabats pliables (118, 120 ; 214, 216 ; 314, 316) s'étend jusqu'à une extrémité libre. Une extrémité libre d'un premier des rabats pliables (118, 120 ; 214 216 ; 314 316) est disposée à une première distance (Wc1, Wc2, Lcf) à partir d'une extrémité libre d'une seconde paire de rabats pliables (118, 120 ; 214, 216 ; 314, 316) lorsqu'elle est sous une forme érigée pour créer un couvercle (190 ; 290 ; 390). La première distance (Wc1, Wc2, Lcf) est égale ou inférieure à une dimension linéaire (Lt1, Wt2) d'un plateau (90) formé à partir de l'ébauche de plateau (10).
