照）。2. Description of the Related Art In a blow molding bottle made of synthetic resin, in which an inner layer forming a deformable inner bag is releasably laminated in an outer layer forming a regular outer shell, the inner volume of the inner layer is reduced. In order to prevent the accompanying deformation, that is, the crushing deformation from becoming indefinite, the outer layer and the inner layer are fixed by adhesion or the like at a part of the outer layer and the inner layer, for example, at least in the mouth cylinder part and the bottom part of the bottle body. (See Japanese Patent Laid-Open No. 4-339759).

In the figure, a bottle body 1 in a state where the cap 8 with a pump is screwed and assembled and the body portion of the cap 8 are shown in a semi-longitudinal view. The bottle body 1 has an outer layer 2 made of high-density polyethylene resin and an inner layer 3 made of nylon Are blow-molded from a parison extruded into a laminated cylindrical shape by a co-extrusion molding means, and a thread for assembling the cap 8 is engraved on the outer peripheral surface of the mouth tube portion 4 having a cylindrical shape. Has been done.

Has an outer diameter sufficiently larger than the outer diameter of the mouth tube portion 4,
It has a flat ring-shaped top surface.

The upper and lower parts of the connecting flange 7a are cut from the bottle body 1 by being cut up and down by K (see FIG. 3), but remain on the bottle body 1 side in a state of being continuously connected to the upper end of the mouth tube portion 4. Becomes the reverse flange 5 (see FIG. 4) as it is.

全に達成することができる。Since the present invention has the above-described structure, the following effects can be obtained. Since the upper end surface of the mouth cylinder, that is, the packing round is formed by the reversal flange formed by bending the upper end of the mouth cylinder from the inside to the outside, the upper end surface of the mouth cylinder is defined as the upper end of the inner layer. Therefore, when the cap is screwed to the mouth cylinder, the upper end of the inner layer is firmly clamped and fixed between the packing of the cap and the upper end of the outer layer. It is possible to firmly and securely achieve immobile fixation of the tubular portion to the outer layer.
