Representative: Yatabe Yoshino 4, Agent 5, Date of amendment order: Self-issued full text correction specification 1, Title of the invention Biaxially Stretched Synthesis) 1 (fat mold tank 2, Claims (1)) In a synthetic+21 fat bottle having a body with a circular cross section formed thinly by biaxial stretching, the bottom wall thereof is A cap-shaped portion with a tapered peripheral wall protrudes inward from the bottle, and step-shaped portions are arranged at approximately equal intervals on the same circumference in the middle of the peripheral wall of the cap-shaped portion. Axially stretched synthetic resin!1!I bottle. (2) The peripheral wall of the cap-shaped portion is characterized by having both the inner and outer surfaces formed in a wave-root shape in cross section with continuous concave portions and convex portions. A two-wheeled stretched synthetic resin bottle according to claim 1. (3) The peripheral wall of the cap-shaped portion is formed into a corrugated plate-like cross section in which both the inner and outer surfaces of the cap-shaped portion are continuous with a concave portion and a convex portion. The synthetic resin bottle according to claim 1, characterized in that a stepped portion is formed in the middle of each concave portion on the in-situ inner surface side.(4) Peripheral wall of the cap-shaped portion is characterized in that both the inner and outer surfaces of the bottle are formed with concave lines and convex lines in a continuous wave-root shape in cross section, and a stepped part is formed in the middle of each convex line in the inner surface of the bottle. A synthetic resin bottle according to claim 1. 3. Detailed description of the invention "Field of industrial application" The present invention is applicable to, for example, drinking water containing carbon dioxide gas or soft drinks that do not contain carbon dioxide gas. Concerning a biaxially stretched synthetic resin bottle suitable for filling. ``Prior art'' In the above-mentioned drinking water, etc., the cost of containers or transportation costs account for a large proportion of the price, and therefore, it is necessary to reduce the cost. has a large effect on the overall I value.Glass bottles have been used as containers of this type, but glass bottles are large, so transportation costs are high, and handling is difficult. In order to eliminate these drawbacks, synthetic resin bottles that have been biaxially stretched to increase their strength and reduce their weight have been used as containers. The above-mentioned conventional synthetic resin bottles generally have insufficient biaxial stretching of the bottom wall, and especially in the case of bottles filled with liquid under high internal pressure, the bottom wall is easily damaged. The object of the present invention is to eliminate such drawbacks. ``Means for solving the problems'' A synthetic resin body having a circular cross-sectional body formed thinly by biaxial stretching. In a bottle, the bottom wall is made to protrude inwardly into a cap-shaped portion with a tapered peripheral wall, and step-shaped portions are arranged at approximately equal intervals on the same circumference in the middle of the peripheral wall of the cap-shaped portion. I let it happen. "Function" By forming the cap-shaped part at the bottom of the bottle, the stretching ratio of the bottom wall of the tank can be increased, and since step-shaped parts are formed at approximately equal intervals in the middle of the circumferential wall of the cap-shaped part, the cap-shaped part can be The peripheral wall of the section further increases the stretching ratio and the impact resistance (h impact strength) of the bottom wall. The synthetic resin bottle according to the invention is preferably made of saturated polyester resin, but any synthetic resin that can increase the mechanical strength of the bottle by biaxial stretching, such as polypropylene or PVC, may be used. The body 2 has a cylindrical shape. From the upper end of the body projects upwardly through the shoulder 3 a neck part 5 which has a threaded part 4 for fitting the cap on its outer surface. The bottom wall 6 is located inside the bottle. The cap-shaped part 7 is made to protrude and its peripheral wall 7a is formed into a tapered shape.In addition, step-shaped parts 7b are attached at approximately equal intervals on the same circumference in the middle of the peripheral wall. As shown in FIGS. 3 and 4, the peripheral wall 7a has a corrugated cross-section with continuous grooves 7c and protrusions 7d on both its inner and outer surfaces, and has a stepped portion in the middle. Alternatively, a stepped portion 7b may be provided in the middle of one of the grooves 7c on the inner surface of the bottle as shown in FIG. 5 or the convex portion 7d on the inner surface of the bottle as shown in FIG. Good, and even better
As shown by the two-dot chain line in the figure, a plurality of solid protruding ribs 8 may be protruded from above and radially from the center of the bottom wall on the inner surface of the lower part of the bottle. It is possible to further increase the strength of the bottom of the bottle by adding a solid protruding rib like this. It is also conceivable to provide the solid protruding rib on the outer surface of the bottom. Solid protruding rib 8...
To form this, as shown in FIG. 7, an intermediate material 10 for biaxial stretching is provided which has solid protruding ribs 11 on the inner or outer surface of the lower part, and this is heated to an appropriate temperature. After that, it may be set in a blow mold and biaxially stretched. The cap-shaped portion, uneven stripes, and stepped portion of the bottom wall of the bottle are connected to the recesses and protrusions provided on the inner wall of the mold cavity.
It is formed by pressing the i-wall parts together. ``Effects of the Invention'' The present invention has the structure described in 2. In a synthetic resin bottle having a body with a circular cross section formed thinly by biaxial stretching, the bottom wall of the bottle has a tapered peripheral wall. Since the step portions 7b are made to protrude inward into the bottle in a cap shape, and the stepped portions 7b are added at approximately equal intervals on the same circumference in the middle of the circumferential wall, the cap is made to protrude inward in a cap shape, compared to when the cap is simply made to protrude in a cap shape. Since the surface area of the circumferential wall of the shaped part is expanded, the v II ratio of the bottom wall can be increased, and the stepped part can increase the rigidity of the bottom wall in order to have a rib function. In order to moderate the extension of the bottom wall by expanding the surface area of the cap-shaped part, it is possible to make the cap-shaped part protrude higher into the bottle. The wall thickness of the grounding wall portion 9 becomes too thin, weakening the strength against internal pressure and external pressure.In the case of the present invention, since a stepped portion is provided in the middle of the cap-shaped portion peripheral wall, only a portion of the intermediate material is moderately thick. Therefore, it is possible to increase the stretching ratio while providing an appropriate wall thickness.If the bottle is made of saturated polyester resin, there will be no leakage of harmful substances such as solvents. Furthermore, it is possible to prevent the generation of toxic gas when incinerated after disposal. 4.
