Abstract

La présente invention concerne un couvercle métallique pour un corps de contenant, en particulier pour un contenant du genre boîte de conserve métallique, lequel couvercle (1 ) comprend (i) une partie centrale (3) formant un panneau central d'obturation, comprenant une partie amovible (5) délimitée par une ligne d'amorce de rupture (4) en forme générale de parallélogramme et équipée d'un organe de préhension (7) muni d'un axe longitudinal (7'), et (ii) une partie périphérique (2) en forme générale de parallélogramme adaptée pour être solidarisée sur ledit corps de contenant. Selon l'invention, la ligne d'amorce de rupture (4) comporte un premier tronçon transversal (4b1) dont une portion aval (4b12), à distance de l'angle de jonction (4c) au niveau duquel est rapporté l'organe de préhension (7), s'étend de telle sorte que, tout au long de sa longueur, les lignes (9) qui lui sont tangentes (9) définissent un angle extérieur (a) supérieur à 45° avec une droite (8) perpendiculaire à l'axe longitudinal (7') de l'organe de préhension (7), ledit angle augmentant sur la longueur de ladite portion aval (4b12), cela de sorte à améliorer le rendement de la force et de l'énergie exercées par l'utilisateur pour déchirer la ligne d'amorce de rupture (4).The present invention relates to a metal cover for a container body, in particular for a container of the metal cans type, which cover (1) comprises (i) a central portion (3) forming a central obturating panel, comprising a detachable portion (5) delimited by a break-off line (4) generally parallelogram-shaped and provided with a gripping member (7) having a longitudinal axis (7 '), and (ii) a portion peripheral (2) generally parallelogram shape adapted to be secured to said container body. According to the invention, the breaking initiation line (4) comprises a first transverse section (4b1) of which a downstream portion (4b12), at a distance from the junction angle (4c) at which the organ is attached. for gripping (7), extends so that along its length, the lines (9) which are tangent to it (9) define an outside angle (a) greater than 45 ° with a straight line (8). perpendicular to the longitudinal axis (7 ') of the gripping member (7), said angle increasing along the length of said downstream portion (4b12), so as to improve the efficiency of the force and energy exerted by the user to tear the breaking initiation line (4).
