Abstract:
1. A bottle container comprising: a container body comprising (i) a cylindrical neck with an opening at its top and having a male thread formed therearound, (ii) a large-width non-cylindrical fluid storage section having a width larger than the cylindrical neck, and (iii) a shoulder that connects the neck to the fluid storage section, said shoulder having steps with risers both extending in a radial direction on its outer surface and having an outer periphery non-cylindrical recess formed inwardly from an outer periphery of the non-cylindrical fluid storage section; a shoulder part comprising (i) a cylindrical piece having a male thread on its outer periphery and a female thread on its inner periphery closer to the center of the shoulder part than is the outer periphery of the shoulder part and having a pouring outlet with a sealed tip, and (ii) a widening section continuing from the cylindrical piece and having (iia) projection-like members provided on its bottom face for engaging with the steps with risers on the shoulder of the container body and (iib) an outer periphery non-cylindrical projection for engaging and fitting with the outer periphery non-cylindrical recess of the shoulder when the female thread of the cylindrical piece and the male thread of the cylindrical neck are engaged, said outer periphery non-cylindrical projection having an outer periphery corresponding to that of the outer periphery non-cylindrical recess of the shoulder; a cap having an unsealing member for piercing the sealed tip at the pouring outlet, and a female thread for engaging with the male thread of the cylindrical piece, said cap having a non-cylindrical outer portion having an outer periphery corresponding to the outer periphery of the shoulder part; and an unsealing prevention member which is a plate-shaped non-cylindrical member with an opening formed at its center through which the shoulder part is inserted to interpose the unsealing prevention member between the cap and the shoulder part when the pouring outlet is not unsealed, where the unsealing prevention member has an outer periphery recess for engaging and fitting with the outer portion of the cap, and has a thickness sufficient to allow the unsealing prevention member to function as a spacer to prevent the unsealing member of the cap from contacting the sealing tip of the pouring outlet.
