ある。2. Description of the Related Art As a typical prior art of a blow molding bottle made of synthetic resin, an inner layer forming a deformable inner bag is releasably laminated inside an outer layer forming a regular outer shell. There is a technique disclosed in Japanese Patent Laid-Open No. 5-310265.

にしている。According to this conventional technique, a slit formed by adhering inner layers to each other and not adhering outer layers to each other is formed on a bottom parting line which is a mold cutting portion formed when a bottle is blow-molded. When the inner liquid formed by the inner layer is deformed and reduced in volume by pouring out and using the content liquid stored in the inner layer, the outside air is allowed to enter between the outer layer and the inner layer through this slit, and thus the outer layer The inner layer can be smoothly peeled off, and the volume reduction deformation of the inner layer due to the use of the content liquid by pouring can be reasonably and favorably performed.

た。However, in the above-mentioned prior art, since the slit, which is the entrance of the outside air between the outer layer and the inner layer, is opened on the bottom surface of the bottle body, the bottle body is heated in a bathroom or the like. When used on the surface where is located, hot water enters between the outer layer and the inner layer from the slit opened on the bottom surface of the bottle, making it easy for dirt and signs to occur, and dripping when the bottle is carried, There was a problem of soiling clothes and surroundings.

とになると云う問題があった。Further, since the slit is formed in the bottom portion forming the leg portion of the bottle body, the mechanical strength of the bottom portion as the leg portion of the bottle body is lowered, and the self-shape retaining ability of the bottom portion is lowered. As a result, the sitting of the bottle becomes unstable, especially when the content liquid is full.
There has been a problem that care must be taken in handling so that the bottom is not impacted.

Applying to a two-layer blow-molded bottle body composed of a flexible synthetic resin inner layer forming a bag, forming the outer layer of the bottle with a synthetic resin material having a lower melting point than the inner layer, and the outer layer of the bottle A punching jig heated to a temperature above the melting point of the material but below the melting point of the inner layer material is pressed against the outer layer part of the body, including the mouth of the bottle, and the air intake hole between the inner layer and this outer layer is formed. Melt forming.

される。[Operation] Since the perforating jig pressed against the outer layer of the bottle is heated to the melting point of the outer layer material or more and less than the melting point of the inner layer material, only the outer layer is melted and the air intake hole is formed in the outer layer. .

て、内層の変形が無理なく良好に達成される。An outer layer forming a regular outer shell and an inner layer forming a deformable inner bag for directly containing the content liquid are laminated in a peelable manner, and the air intake is provided between the outer layer and the inner layer. Since it is opened to the outside by the holes, if a pressure reduction occurs in the inner layer and the inner layer tries to deform in a direction to reduce its internal volume, the outer layer and the inner layer are intruded by the outside air from the air intake holes into the outer layer. Delamination of the inner layer is smoothly achieved, and the deformation of the inner layer is achieved reasonably and satisfactorily.

殻形状を維持し、壜体の外観形状を一定に保持する。At this time, the outside air penetrates into the outer layer through the air intake hole, and only the inner layer is separated from the outer layer and deforms in the direction of decreasing the volume, so that the outer layer is not subjected to an external force that causes deformation, Maintains a regular outer shell shape without deformation and maintains a constant bottle appearance.

することはない。Since the air intake hole is located at any desired position of the body including the mouth, the position of the air intake hole is set to be slightly different so that the hot water is located on the surface. Even if the bottle is placed, it will be located above and away from the surface on which this hot water is located, so that the hot water on this surface will not enter between the outer and inner layers through the air intake holes.

なる。Further, the air intake hole can be arbitrarily selected at a place where there is no fear of deteriorating the strength of the bottle, and can be bored at this place, so that the outer layers of the die cutting parts on the bottom of the bottle are separated from each other. Since the bonded state can be maintained without being separated, the bottom of the bottle maintains mechanical strength equivalent to the bottom of a normal synthetic resin blow-molded bottle.
