Abstract

Proceso para la manufactura de botellas plásticas lavables encaliente especialmente de PET que pueden ser inspeccionadas a través del fondo, en donde- el área de fondo (10) de la botella es moldeado sobre un frustocono interiormente ahusado (1) en un primer paso de moldeo por soplado;- después de la remoción del molde o encogimiento el fondo de la botella frustocónica cambia a una estructura ondulada (10´, 10", 10w) -visto en sección transversal-, cuyo punto de inflexión (10w) es localizada axialmente más alto que el anillo de parado (10r) de la botella (10).Un aparato para llevar a cabo el proceso según se estableció en las reivindicaciones 1 ó 2, en donde- unas preformas plásticas son moldeadas por soplado a una temperatura más alta bajo presión más alta en un primer molde de soplado con un fondo frustocónico (1; 1c, 1a, 1b);- un dispositivo de control se proporciona, el cual abre el primer molde de soplado para permitirle al contenedor intermedio moldeado en el primer molde de soplado encogerse;- un segundo molde de soplado se proporciona teniendo un fondo en forma esencialmente de domo (20, 20a, 20b, 20c, 20d).El equipo según se estableció en la reivindicación 3, en donde al menos uno de los fondos (20;1) de los moldes de soplado es diseñado como un inserto metálico.Process for the manufacture of especially PET hot washable plastic bottles that can be inspected through the bottom, where- the bottom area (10) of the bottle is molded on an internally tapered frustoconus (1) in a first molding step by blow; - after removal of the mold or shrinkage the bottom of the frusto-conical bottle changes to a corrugated structure (10´, 10 ", 10w) -seen in cross section-, whose inflection point (10w) is located axially more higher than the stop ring (10r) of the bottle (10) .An apparatus for carrying out the process as set forth in claims 1 or 2, wherein- plastic preforms are blow molded at a higher low temperature highest pressure in a first blow mold with a frusto-conical bottom (1; 1c, 1a, 1b); - a control device is provided, which opens the first blow mold to allow the intermediate container molded into the pri shrink blow mold; - a second blow mold is provided having an essentially dome-shaped bottom (20, 20a, 20b, 20c, 20d). The equipment as set forth in claim 3, wherein at least one of the bottoms (20; 1) of the blow molds are designed as a metal insert.
