A biodegradable molded article and a container using the molded article, exhibiting an improved heat resistance. The molded article is obtained by injection molding a polylactic acid resin, wherein the molded article comprises poly-L-lactic acid containing less than 4 mol% of D-lactic acid. The molded article has a crystallized portion at least locally, having a ratio of the crystallizing heat quantity to the melting heat quantity (|.DELTA.Hc|/.DELTA.Hm), which ratio is not more than 0.7 in a temperature rising chart obtained by differential scanning calorimetry (DSC).
L'invention concerne un article moulé biodégradable ayant une résistance à la chaleur améliorée et un récipient utilisant l'article moulé. Un article moulé obtenu par moulage par injection d'une résine d'acide polylactique, l'article moulé comprenant un acide poly-L-lactique contenant moins de 4 % par mole d'acide D-lactique. L'article moulé est doté, au moins dans une partie de celui-ci, d'une zone cristallisée présentant un rapport d'énergie de cristallisation/énergie de fusion (|?Hc|/?Hm) de 0,7 ou moins, dans un tableau de chauffage utilisant un calorimètre à balayage différentiel (DSC).
