Abstract

Perfeccionamientos en la formación de paredes de recipientes con un área abrible, del tipo que comprende, formar en la pared un trayecto donde se ha de romper la pared, cuyo trayecto es un debilitamiento en el material de la pared que conecta la parte abrible y la parte fija que ha de quedar en su sitio después de abierto el recipiente, y colocar la pared entre útiles de un molde, caracterizados porque se forma el útil sobre una primera cara de la pared con un rebajo de ruptura con el que coincide el trayecto de debilitamiento, y en la otra cara de la pared con un canal de nervaduras que se extiende a lo largo del trayecto y abarca el trayecto y una región de la pared a cada lado del trayecto; porque se inyecta material moldeable en el canal de la nervadura para formar una nervadura adherente a la otra cara de la pared con el fin de desplazar aquellas regiones de la pared de las partes de pared abrible y fija inmediatamente adyacentes al trayecto en el rebajo de ruptura en el útil del molde, para reducir aún más la resistencia de la conexión entre las partes de la pared abrible y fija y para formar un cierre estanco en las regiones de la pared desplazadas por adherencia a la pared junto a cada región desplazada y quitando la pared del molde, siendo abrible la pared resultante por tracción ejercida sobre la nervadura para desconectar las partes abrible y fija de la pared.
