Method and device for producing preforms

본 발명은 후속 스트레치 블로우 몰딩에 대해 최적화된 기저 기하학적 형상을 갖는 예비성형체를 제조하기 위한 방법 및 장치에 관한 것이다. 사출 몰드 내에서 제조된 예비성형체는 냉각식 제거 슬리브 내에서 제거되고 집중적 접촉 냉각에 의해 샤프트 내에서 냉각되며 냉각 슬리브의 특정 윤곽으로 인해 돔형 예비성형체 단부와의 냉각 접촉이 이루어지지 않는다. 그 결과, 이 돔형 단부의 재-가열을 고려하여, 이는 벽 두께에 영향을 미치고 블로우-몰딩 공정에 대해 더욱 선호되는 신규한 기하학적 형상으로 기계적으로 변형될 수 있다. 후속 블로우-몰딩 공정에서, 이러한 변형된 예비성형체는 주요하게는 병 내에서 더 양호하게 분포된 중합체 재료가 상당한 재료 절감을 야기하고 고 품질의 병 기저를 제공하는 이점을 갖는다. The present invention is directed to a method and apparatus for producing preforms having an underlying geometric shape optimized for subsequent stretch blow molding. The preforms produced in the injection mold are removed in a cooled removal sleeve and cooled in the shaft by intensive contact cooling and due to the particular contour of the cooling sleeve there is no cooling contact with the domed preform end. As a result, taking into account the re-heating of this domed end, it can be mechanically deformed into a novel geometry that affects the wall thickness and is more preferred for blow-molding processes. In the subsequent blow-molding process, this modified preform has the advantage that the polymer material, which is better distributed in the bottle, mainly results in significant material savings and provides a high quality bottle base.

Method of making clear transparent polypropylene containers

Biaxially oriented low cost polyolefin bottles of improved optical clarity, gloss, and strength, and useful for packaging materials such as liquid detergents, shampoos, pharmaceuticals and intravenous solutions, are prepared by stretch blow molding polypropylene homopolymer co-polymer and allomer parisons or preforms which are formed from low temperature melts at temperatures just above the melting points of the polymers and allomers, and are injected at constant rates against cold polished mold surfaces at relatively low pressures and at slow rates to avoid melt fractures. Melt temperatures of from 490° to 700° F. are preferred for polypropylene blow mold type polymers and allomers. Polished beryllium copper mold surfaces are desired for high luster gloss finishes. Mold temperatures of from 30° to 80° F. are preferred. Injection molding with a high compression ratio of 3 to 3.5 for insuring a homogeneous melt is preferred with a relatively slow injection rate to fil the mold cavity of about 3 to 10 seconds. The low temperature molding limits the size and increases the number of spherulites that form as the melt cools and solidifies thus minimizing crystallinity in the parison. The low mold temperatures provide faster molding cycles, increasing production and reducing costs but the injection rate is sufficiently slow to avoid melt fracture. The strength blow molding is preferably conducted at temperatures just below the amorphous flow temperature of the parison with temperatures of about 295° F. being sufficient for the polypropylene copolymer and about 325° F. below satisfactory for the polypropylene homopolymer.

DEVICE AND METHOD FOR MEASURING THE WALL TEMPERATURE OF A CONTAINER BLANK

Biaxially-drawn blow-molded container having excellent heat resistance and method for producing the same.

본 발명은 이축-연신-팽창-성형된 용기 및 이를 제조하는 방법에 관한 것이다. 복잡한 가열 시스템을 사용하지 않는 2차 팽창 성형시에는 밑바닥부의 재연신비가 적으나, 이때 프레폼 제품을 1차 팽창 성형 처리하므로써 수득된 제2제품은 밑바닥부에서 차별적으로 수축되고, 평평한 형태 또는 중앙부가 용기의 안쪽으로 패이고 주변부는 평평한 형태의, 2차 팽창 성형처리 이전의 제3제품 또는 제4제품이 수득된다. 이 방법을 통해 수득된 병은, 두께 및 결정도가 배럴의 중앙부와 거의 동일하며 상당히 연신된 밑바닥을 갖는다. 내열성의 병은 그 밑바닥부의 강도가 우수하며 진공압에서 대칭적 패널-참강 안정성을 갖는다. The present invention relates to a biaxially-stretching-expansion-molded container and a method of making the same. In the case of secondary expansion molding without complicated heating system, the bottom redrawing ratio is low, but the second product obtained by the primary expansion molding of the preform product is contracted differentially in the bottom, and is flat or centered. The third product or the fourth product before the secondary expansion molding treatment is obtained, which is dug into the inside of the container and the periphery is flat. The bottles obtained through this method have a substantially elongated bottom with almost the same thickness and crystallinity as the center of the barrel. Heat resistant bottles have good strength at the bottom and have symmetrical panel-chamfer stability at vacuum pressure.

Patent FR2389479A1

Procédé et dispositif de fabrication de corps creux en téréphtalate de polyéthylèneglycol. Partant d'une ébauche ou paraison en matière chaude, on refroidit cette ébauche ou paraison rapidement à une température inférieure ou égale à la température de cristallisation et proche de celle-ci, à la suite de quoi on provoque une expansion de la matiere à un taux suffisant pour obtenir une bi-orientation. On obtient des corps creux de très bonnes qualités résistant à la pression et aux chocs. Method and device for manufacturing hollow bodies made of polyethylene glycol terephthalate. Starting from a blank or parison of hot material, this blank or parison is rapidly cooled to a temperature less than or equal to the crystallization temperature and close to the latter, following which an expansion of the material to a sufficient rate to obtain a bi-orientation. We obtain hollow bodies of very good qualities resistant to pressure and shocks.
