Title
(EN) BOTTLE BODY MADE OF SYNTHETIC RESIN
(FR) CORPS DE BOUTEILLE FABRIQUE EN RESINE SYNTHETIQUE
Abstract
(EN)
This invention relates to the structure of a large type bottle body made of polyethylene terephthalate resin formed by biaxial stretching blow molding having trunk parts (2) in the shape of angular tube. A central circumferential groove (3) is circumferentially provided nearly at the center of the trunk part (2), and the angle of inclination of the both side walls (4) of said central circumferential groove (3) with respect to the direction of center axis of a bottle body (1) is set within a range of 21° - 28°. A recessed part (7) whose bottom wall serves as a deformed panel wall (8) to cushion the depressurization is provided depressed in the center part of each flat wall (6) of the trunk part (2), a deformed circumferential groove (9) that curves inverted along the circumferential edge of the aforementioned deformed panel wall (8), many rib streaks (21) are transversely provided in parallel above and below on the aforementioned deformed panel wall (8), the radius of curvature of the mountain parts forming said rib streaks (21) is set larger than the radius of curvature of the valley parts between said mountain parts, and, in addition, the both end parts of the aforementioned valley parts are made shallow along a large radius curvature. The top edge of the trunk part (2) is made to the shape of regular polygon having twice as many angles as the aforementioned trunk part (2) has, and the bottom edge part (31) of a shoulder part (11) connectively provided on the upper edge of said trunk part (2) is made to the shape of frustum of regular pyramid having twice as many angles as the aforementioned trunk part (2) has. The connnecting end edge from first wall parts (34, 41) among the two wall surface parts connected through the curved line to second wall parts (33, 42) is slightly extended to the sides of the aforementioned second wall parts (33, 42), and the extended connecting end edge of the first wall parts (34, 41) is connected to the connecting end edge of the second wall parts (33, 42) through the ridge line wall part (44) curved/inverted with a small radius of curvature.

Cette invention concerne la structure d'un corps de bouteille de grande taille fabriqué en résine de polytéréphtalate d'éthylène formé par extrusion-soufflage à étirage biaxial et possédant des éléments de tronc (2) en forme de tube d'angle. Une rainure circonférentielle centrale (3) est prévue près du centre du tronc (2), et l'angle d'inclinaison des deux parois latérales (4) de ladite rainure circonférentielle centrale (3) par rapport au sens de l'axe médian d'un corps de bouteille (1) est fixé dans la plage de 21° à 28°. Une partie évidée (7), dont le fond sert de paroi déformée (8) afin d'amortir la dépressurisation, est prévue dans la région centrale de chaque paroi plate (6) du tronc (2). Une rainure circonférentielle déformée (9) présente une courbure qui suit le bord circonférentiel de la paroi déformée (8) précitée. Une pluralité de nervures parallèles (21) sont ménagées en position transversale en haut et en bas sur la paroi déformée (8) précitée. Le rayon de courbure des crêtes formant lesdites nervures (21) est plus élevé que celui des creux situés ente lesdites crêtes, et d'autre part, les deux extrémités desdits creux sont peu pofondes le long d'un rayon de courbure élevé. Le bord supérieur du tronc (2) présente la forme d'un polygone régulier qui possède deux fois plus d'angles que le tronc (2) précité, et le bord inférieur (31) d'un épaulement (11) prévu relié au bord supérieur dudit tronc (2) présente la forme d'un tronc de pyramide régulière qui possède deux fois plus d'angles que le tronc (2) précité. Le bord connecteur terminal des premières parois (34, 41) entre les deux éléments superficiels de paroi reliés par l'intermédiaire de la ligne courbée aux deuxièmes parois (33, 42) est légèrement allongé jusqu'aux bords desdites deuxièmes parois (33, 42), et le bord connecteur terminal des deuxièmes parois (34, 41) est relié au bord connecteur terminal des deuxièmes parois (33, 42) grâce à la paroi à lignes de crêtes (44) courbées/inversées et à faible rayon de courbure.
