A metal container with thread capable of preventing such a defect that the strength of a lower end of a mouth part and an upper end of a shoulder part of a container main body is non-resistant to a pressing force in radial and axial directions, and a part of the container may be collapsed or buckled during a capping operation where content is filled into the container and cap is fitted to the container automatically by a machine, characterized in that at least one or more inwardly curving smooth annular recessed parts and at least one or more outwardly curving smooth annular projected parts are formed in an area ranging from the lower end of the mouth part of the container main body to around the upper end of a tapered shoulder part increasing gradually in radial direction.
Un récipient de métal avec un filetage permettant d'éviter, d'une part que l'extrémité de l'embouchure et l'extrémité supérieure de l'épaulement du ventre du récipient ne puissent résister à la force d'application radiale et longitudinale, et d'autre part qu'une partie du récipient ne s'écrase ou se déforme pendant la pose de couvercle lorsqu'on utilise une machine pour le remplissage et le bouchage du récipient. En l'occurrence, la zone entre le bas (2a) du col (2) du récipient et le déboucher du goulot (3a) est entourée formations annulaires faisant alterner rainures (4) et nervures (5) s'effilant graduellement radialement.
