Abstract

Tapa metálica para un cuerpo de recipiente, en particular para un recipiente del tipo lata de conservas metálica, comprendiendo dicha tapa (1) (i) una parte central (3) que forma un panel central de obturación, y (ii) una parte periférica (2) adecuada para ser solidarizada sobre dicho cuerpo de recipiente, comprendiendo dicha parte central (3) una parte amovible (5) delimitada por una línea de inicio de rotura (4) en forma general de paralelogramo, y estando dicha línea de inicio de rotura (4) compuesta por dos tramos longitudinales (4a) y por dos tramos transversales (4b), estando dicha parte amovible (5) de la tapa (1) equipada, a nivel de una de sus superficies, con un órgano de prensión (7) compuesto por dos partes (7a, 7b) por las cuales pasa un eje longitudinal (7'): - una primera parte (7a) solidarizada con dicha parte amovible (5) y una segunda parte (7b) de prensión propiamente dicha, estando dicha primera parte (7a) del órgano de prensión (7) solidarizada a nivel de un ángulo de unión (4c) correspondiente a la unión entre un primer tramo longitudinal (4a2) y un primer tramo transversal (4b1) de dicha línea de inicio de rotura (4), comprendiendo dicho primer tramo longitudinal (4a2) y dicho primer tramo transversal (4b1) de dicha línea de inicio de rotura (4), cada uno, dos partes: (i) una porción aguas arriba (4a21, 4b11) dispuesta a nivel de dicho ángulo de unión (4c), destinada a ser desgarrada por una operación de pivotado inicial de dicho órgano de prensión (7) y (ii) una porción aguas abajo (4a22, 4b12), alejada de dicho ángulo de unión (4c), constituida por la longitud restante de dicho tramo (4a2, 4b1) y destinada a ser desgarrada por una operación posterior de tracción sobre el órgano de prensión (7), extendiéndose dicha porción aguas abajo (4b12) del primer tramo transversal (4b1) de la línea de inicio de rotura (4) de tal manera que, a lo largo de toda su longitud, las tangentes (9) a la misma definen un ángulo exterior (α) que es superior a 45º, con una recta (8) perpendicular a dicho eje longitudinal (7') del órgano de prensión (7), aumentando dicho ángulo exterior (α) por la longitud de la porción aguas abajo (4b12) del tramo transversal (4b1) de la línea de inicio de rotura (4), a partir de su porción aguas arriba (4b11), caracterizada por que la porción aguas abajo (4b12) del primer tramo transversal (4b1) de la línea de inicio de rotura (4) es de forma general curva, dividida en dos partes: - una primera parte en forma general de arco de elipse, en el lado de la porción aguas arriba (4b11), y - una segunda parte en forma general de arco de círculo, para la conexión con el segundo tramo longitudinal (4a1).Metal lid for a container body, in particular for a container of the type of metal can, said lid (1) (i) comprising a central part (3) forming a central sealing panel, and (ii) a peripheral part (2) suitable for being supported on said container body, said central part (3) comprising a removable part (5) delimited by a breaking start line (4) in general parallelogram form, and said starting line being of breakage (4) composed of two longitudinal sections (4a) and two transverse sections (4b), said removable part (5) of the cover (1) being equipped, at the level of one of its surfaces, with a clamping element ( 7) composed of two parts (7a, 7b) through which a longitudinal axis (7 ') passes: - a first part (7a) in solidarity with said removable part (5) and a second part (7b) of proper pressure, said first part (7a) of the clamping body (7) being in solidarity at level d and a joint angle (4c) corresponding to the joint between a first longitudinal section (4a2) and a first transverse section (4b1) of said breaking start line (4), said first longitudinal section (4a2) and said first cross section (4b1) of said breaking start line (4), each, two parts: (i) an upstream portion (4a21, 4b11) arranged at the level of said joint angle (4c), intended to be torn apart by an initial pivoting operation of said clamping member (7) and (ii) a downstream portion (4a22, 4b12), away from said joint angle (4c), constituted by the remaining length of said section (4a2, 4b1 ) and intended to be torn by a subsequent traction operation on the clamping member (7), said portion extending downstream (4b12) of the first transverse section (4b1) of the breaking start line (4) such that , along its entire length, the tangents (9) to it define an angle ex terior (α) which is greater than 45 °, with a straight line (8) perpendicular to said longitudinal axis (7 ') of the clamping element (7), said exterior angle (α) increasing by the length of the downstream portion (4b12 ) of the transverse section (4b1) of the breaking start line (4), from its upstream portion (4b11), characterized in that the downstream portion (4b12) of the first transverse section (4b1) of the line of Breaking onset (4) is generally curved, divided into two parts: - a first part in general form of ellipse arc, on the side of the upstream portion (4b11), and - a second part in general form of arc of circle, for the connection with the second longitudinal section (4a1).
