Abstract

Se describe un vaso de material plástico que incorpora un agente de espumacion o formacion de espuma que tiene porciones de pared delgada, a saber una base (101), una pared lateral inferior (102), y una pared lateral superior (103). Estas porciones tienen su espesor de pared determinado por el espacio libre de la parte del molde. El vaso también tiene porciones de pared gruesa, a saber la esquina (104), la banda (105) y la orilla o reborde (106), en las cuales ocurre la espumacion después de la apertura del molde, de modo que el espesor de la pared es incrementado más allá de aquel proporcionado por el molde.
