Patent ID: 7434702

Claim:
A bottle container made of resin, comprising: a cylindrical barrel having an outer circumferential surface, and having a bottom; a cylindrical neck portion provided at an upper end of said cylindrical barrel, said cylindrical neck portion having a diameter smaller than that of said cylindrical barrel, wherein an upper part of the bottle container and a lower part of the bottle container are directly connected to each other at a connecting portion of said cylindrical barrel so as to form an annular connecting groove defined by connecting surfaces of said upper and lower parts; a cover member arranged within said annular connecting groove and fused with said upper and lower parts within said annular connecting groove so as to fix said upper and lower parts together and liquid-tightly cover said connecting surfaces of said upper and lower parts, and so as to shield said connecting surfaces from outside and integrate said connecting surfaces of said upper and lower parts, said cover member having an outer circumferential surface, wherein said outer circumferential surface of said cover member is aligned with said outer circumferential surface of said cylindrical barrel such that no portion of said cover member protrudes outwardly beyond said outer circumferential surface of said cylindrical barrel in a radial direction, said outer circumferential surface of said cover member thereby being flush with said outer circumferential surface of said cylindrical barrel; an annular recess formed in said upper part; and an annular recess formed in said lower part, wherein said annular connecting groove is defined by said annular recesses of said upper and lower parts, and wherein said cover member is liquid-tightly attached to said annular connecting groove.
