Abstract

Un método y aparato para la formación de contenedores de doble pared con la estructura de dos contenedores adyacentes y conectados integralmente que se extienden en la misma dirección con un espacio de aire entre ellos, moldeados por estirado - soplado como cuerpos individuales de material termoplástico, y adecuados para su producción en masa. Se forma una preforma tubular termoplástica y luego se acondiciona térmicamente. La preforma tubular acondicionada térmicamente se estira mecánicamente longitudinalmente y se forma por soplado hacia afuera por presión de gas para asumir de manera conformante y elástica la preforma tubular en la forma de un conjunto de cavidades de molde con forma de primer contenedor doble para formar primero un contenedor conectado integralmente a un segundo contenedor, con ambos contenedores extendiéndose en direcciones opuestas. A continuación, se aplica acondicionado térmico adicional para ajustar el calor según sea necesario al segundo contenedor moldeado por estirado - soplado y, si se considera pertinente, al menos parte del primer contenedor. Luego, al menos un pistón de inversión perfilado con forma de miembro de molde macho con una configuración de superficie externa que define la configuración de superficie interna del articulo a ser conformando y se proporciona un conjunto de cavidades de molde en forma de segundo contenedor con una configuración en forma de contenedor simple junto con uno o más dispositivos de estabilidad de la pared que se aplican a al menos parte de la(s) superficie(s) de la pared de uno o ambos de los dos contenedores moldeados por estirado - soplado conectados integralmente, de modo que la(s) pared(es) lateral(es) del segundo contenedor más pequeño no están sustancialmente en contacto con el conjunto de cavidades de molde en forma de segundo contenedor y puede invertirse al menos parcialmente de manera inversa, mientras que al mismo tiempo la pared inferior del segundo contenedor más pequeño al menos no se invierte sustancialmente, para que el segundo contenedor más pequeño se convierta sustancialmente en una imagen de espejo de un segundo contenedor más pequeño invertido que se extiende en la misma dirección e interior al primer contenedor.
