Embodiment Construction

[0015] Such as figure 1 with figure 2 As shown, a bottle-shaped container 1 made of polyethylene terephthalate (hereinafter referred to as PET) includes a cylinder 3 having a bottom 2 and a cylinder neck 4 having a smaller diameter than the cylinder 3 . At the upper end of said barrel 3 , the bottle-shaped container 1 is divided vertically into two parts, an upper part 5 and a lower part 6 . Annular grooves 7 and 8 are provided on the outer peripheries of the lower end of the upper part 5 and the upper end of the lower part 6 . The annular groove 7 is composed of the lower end ring 11 of the upper part 5 and the hook-shaped ring protrusion 9 that is arranged on the lower surface of the lower end ring 11 and is bent outward. The annular groove 8 is formed by the upper end shoulder 12 of the lower part 6 and the A hook-shaped ring protrusion 10 is formed on the upper surface of the upper shoulder 12 and is bent outward. Said respective ring projections 9 and 10 form the boun...

Abstract

The present invention provides a bottle container made of resin, which comprises a cylindrical barrel with a bottom and a cylindrical neck portion with a diameter smaller than that of the barrel,said bottle container further comprising an upper part and a lower part divided into two parts by dividing at an upper end or a lower end of the barrel, and under the condition that the upper part and the lower part are connected with each other, said two parts are integrated by a cover member for liquid-tightly covering connecting surfaces of said two parts to shield the connecting surfaces from outside and to integrate the two parts with each other.

Description

technical field [0001] The present invention relates to a resin-made bottle-shaped container for containing liquid substances, said container comprising a cylindrical neck at the upper end portion of a bottomed cylindrical cylinder having a diameter smaller than that of the cylinder. The invention also relates to a method of manufacturing said bottle-shaped container. For example, the present invention relates to a bottle-shaped container made of resin for containing a liquid cosmetic material such as mascara and a method of manufacturing the same. Background technique [0002] Conventionally, a resin-made bottle-shaped container including a bottomed cylinder and a cylindrical neck having a smaller diameter than the cylinder has been produced by blow molding (for example, see Japanese Patent Laid-Open No. 2001-113589). However, this blow molding method is only capable of producing a bottle-shaped container having a thickness of 3 mm for most of the parts except the neck. I...
