る。[Problems to be Solved by the Invention] Generally, a bottle-type infusion plastic container is formed by blow molding a thermoplastic material, and a hanging piece is integrally formed on the bottom surface of the body at the time of blow molding. However, when the hanging piece is thin, it is easily twisted or deformed, and even if the hanging piece is stored in the concave portion of the bottom surface of the body part, the hanging piece protrudes from the bottom surface, which hinders the self-supporting property of the container. .

溜りが生じて、外観が損なわれるという問題が生じる。However, in order to eliminate the above inconvenience, the hanging piece may be made relatively thick. However, if the wall thickness of the hanging piece that is integrally formed during blow molding is made thick enough, the hanging piece molding cavity becomes deeper than the thickness of the parison, and even if the mold is closed, the hanging piece molding cavity parison is sufficiently thick. Since it is in an uncompressed state, air remains inside the parison during blow molding or between the parison and the surface of the hanging piece molding cavity, causing air traps inside or on the hanging piece, impairing its appearance. The problem arises.

スチック容器を提供することを目的とするものである。Therefore, the technical problem of the present invention is to solve the former inconvenience in the conventional one and to solve the latter problem, in which the hanging piece is formed to be thick as a whole to prevent twisting or deformation. While preventing and improving the strength, it is possible to completely immerse and store in the bottom surface of the body part without impairing the self-supporting property of the container, and further, it is a curved concave portion substantially along the periphery of the hanging hole of the hanging piece. By forming the recess independently in the hanging piece without connecting it to the end of the hanging piece, Pasulin is sufficiently compressed in the hanging piece forming cavity during blow molding so that the hollow part is formed in the hanging piece. To prevent the occurrence of air traps and air traps, and to improve the appearance of the hanging piece, and even if a recess is formed in the hanging piece, the hanging piece does not connect to the end surface of the hanging piece. Since it is independent inside, the bending strength is It is an object to provide an infusion plastic container provided with a not Nawa Tsuhen.

Even if it is formed to improve the strength, the suspension piece molding cavity is filled with Pasulin and is sufficiently compressed.
Therefore, a hollow portion or an air pocket is not formed in the hanging piece, and the appearance is not impaired. Further, even if a recess is formed in the hanging piece, the recess is formed independently in the hanging piece without being connected to the end surface of the hanging piece, so a hanging piece that does not impair bending strength can be obtained. To be

The hanging piece 4 has a hanging hole 8. There is. The hanging piece 4 is formed such that its wall thickness t is approximately twice as thick as the wall thickness t 1 of the bottom surface 6 of the body portion 2, and the hanging piece 8 is hung around the hanging hole 8 from its lower part so as to surround both sides. A concave portion 9 is formed in a U shape substantially along the periphery of the hole 8. The recess 9 is independently formed in the hanging piece without being connected to the end surface of the hanging piece 4. The hanging piece 4 has a partial thin portion 10 formed by the recess 9. The width of the recess 9 is narrower than the diameter of the hanging hole 8, and the depth thereof is about one third of the wall thickness of the hanging piece 4.

がない。According to the infusion liquid container 1 configured as described above, since the hanging piece 4 has the partial thin portion 10 formed by forming the concave portion 9 around the hanging hole 8, the hanging piece 4 is formed at the time of blow molding. Even if is formed to have a relatively thick wall, it is possible to fill the inside of the hanging piece forming cavity with the parison and obtain a sufficiently compressed state. Therefore, the hanging piece 4 can be made relatively thick to improve the strength so as not to be twisted or deformed, and the hanging piece 4 can be completely retracted and stored in the bottom surface 6 of the body portion 2 to make the container self-supporting. You can make sure you don't lose your sex
Further, it is possible to prevent a hollow portion or an air pool from being formed in the hanging piece 4, and to make the hanging piece 4 excellent in appearance. In addition, even if the recess 9 is formed in the hanging piece 4, since the recess 9 is independently formed in the hanging piece without being connected to the end surface of the hanging piece 4, the concave portion 9 is formed by the hanging piece 4. The bending strength of the hanging piece 4 is not impaired at all by the action of the ribs on the portion 4.

The self-supporting property is not impaired, and the concave portion is a curved shape substantially along the periphery of the hanging hole of the hanging piece, and the concave portion is formed independently in the hanging piece without being connected to the end surface of the hanging piece. As a result, the parison is sufficiently compressed in the hanging piece molding cavity during blow molding to prevent hollow parts and air traps from forming in the hanging piece, which makes the hanging piece excellent in appearance and the hanging piece. Even if a recess is formed in one piece, the recess is independent of the end surface of the hanging piece and is independent in the hanging piece, so that the bending strength is not impaired. There is an effect that can be obtained.
