Abstract

1 / 1 resumo “prã‰-forma sem um anel de suporte para a produã‡ãƒo de recipientes de plãstico, uso de uma prã‰-forma, e, recipiente de plãstico” ㉠descrita uma prã©-forma para a produã§ã£o de recipientes de plã¡stico, em particular garrafas de plã¡stico, em um mã©todo de moldagem por sopro com estiramento, cuja prã©-forma tem um corpo da prã©-forma essencialmente alongado (2), cuja extremidade longitudinal ã© feita de uma maneira fechada. na sua extremidade longitudinal oposta, o corpo da prã©- forma conecta em uma seã§ã£o de estrangulamento (3) que ã© provida com uma abertura de vazamento (4), em cuja parede externa (5) dispositivos de aperto (6) para aperto positivo de uma parte de fechamento equipada com dispositivos de encaixe correspondentes sã£o feitos. na transiã§ã£o (15) do corpo da prã©-forma (2) para a seã§ã£o de estrangulamento (3), a prã©-forma (1) sem um anel de suporte tem um flange rotativo (8) que ã© anular pelo menos em alguns lugares e que estende-se radialmente acima de uma parede externa (7) do corpo da prã©-forma (2). em uma ã¡rea entre o flange (8) e o dispositivo de aperto (6), uma ranhura anular perifã©rico (9) ã© feito na seã§ã£o de estrangulamento (3). a ranhura anular (9) ã© delimitada pelo flange (8) e, na direã§ã£o dos dispositivos de aperto, por um colar externo, que estende-se obliquamente de uma base da ranhura anular (9) atã© a parede externa (7) da seã§ã£o de estrangulamento (3). o colar externo (10) que corre obliquamente forma um colar interno circunferencial (12) que ã© anular pelo menos em alguns lugares em uma parede interna (11) da seã§ã£o de estrangulamento (3), cujo colar, visto na direã§ã£o do corpo da prã©-forma (2), estende-se axialmente acima da ranhura anular (9) e estende-se essencialmente sem recortes atã© uma parede interna (13) do corpo da prã©-forma (2).
