    Abstract: PURPOSE:To enable non-destructive measurement for residual stress or strain of a plastic moulded bottle, and conduct smoothly the successive measurements of the bottle on various physical properties without changing its internal stress or strain for the measurement. CONSTITUTION:A deflecting plate and an illuminating device 4 are fixed in the inside of a table on which a bottle 1 is placed, and an optical fiber scope 15 is inserted into the bottle 1 from the mouth. An image which is sensed by the scope 15 and picked up by a CCD camera 17 through a deflecting plate 16 placed in the outside of the bottle is sent to an image processor 10 for binarization and noise-processing and displayed on a monitor 11, so that the internal stress and strain can be measured by observing the patterns of interference fringe.

    Abstract: PURPOSE:To obtain a fluorine contg. aromatic sulfonic acid catalyst excellent in water repellency and highly active even in the presence of water by bonding a substituted aryl group in a specific structure to the matrix of an inorg. substrate. CONSTITUTION:An aryl group with fluorine and sulfonic acid group introduced thereinto is bonded to the matrix of an inorg. substrate such as zirconium compound, mica and montomorillonite, thereby obtaining on the matrix the fluorine contg. aromatic sulfonic acid catalyst linked with a substituted aryl group of the general formula I (wherein X is F or fluorine contg. 1-14C alkyl group which may contain ether oxygen atoms, Ar is aryl group, (n) is an integer of 1-5 and (m) is an integer of 1-3). This catalyst is highly active against acid catalytic reaction such as esterification and Fries rearrangement and capable of maintaining its high activity even in the presence of water.

    Abstract: PURPOSE:To quickly remove an adsorbed material from a polyester bottle to enable the reuse of the bottle by contacting a polyester bottle having a bottle body part having a specific average crystallinity with water, steam, etc., at a specific temperature, thereby desorbing the material adsorbed on the bottle. CONSTITUTION:A polyester resin (e.g. polyethylene terephthalate) is molded by an injection molding machine. The formed preform is heated to the surface temperature of 90-100 deg.C at the middle of the preform body part and formed by a drawing blow molding with a molding machine to obtain a polyester bottle 1 having an average crystallinity of 32-70% at the body part 4 of the bottle. Methanol (or p-xylene) is poured into the bottle 1, left standing at 25 deg.C for 7 days and discharged from the bottle. The bottle is washed with distilled water of 20 deg.C and dried to effect the adsorption of methanol (or p-xylene) to the bottle and the bottle 1 is brought into contact with water or steam of 40-150 deg.C to quickly desorb and remove the material adsorbed on the polyester bottle 1.

    Abstract: PURPOSE:To reduce the distribution cost at the time of storage or transport, etc., by reducing the volume of a container made of a synthetic resin under an empty condition smaller than the volume under a condition in which a content is filled. CONSTITUTION:A container 1 made of a synthetic resin consists of a mouth part 2 without flexibility which is formed in such a manner that a cap can be fastened on, body part 3 with flexibility which has a larger diameter than the mouth part 2 and has a low rigidity, and a bottom part 4 which has a higher rigidity and is thicker than the body part 3. When the container 1 made of a synthetic resin is under an empty condition, i.e., a content is not filled inside, the body part 3 with flexibility is narrowed wholly from the mouth part 2 to the bottom part 4, and the volume is reduced. At this time, the body part 3 extends in the lateral direction for the portion which is narrowed, and is deformed into a flat plate shape. Thus, the volume of the container 1 made of a synthetic resin under an empty condition is reduced from the volume under a filled condition, and the container 1 is carried or stored under this condition.

    Abstract: PURPOSE: To obtain an autonomous bottle which can be reused by a method wherein a bottle is filled with a carbon dioxide-containing beverage having a specified volume at a specified temperature, changes of a bottle height and a barrel diameter at a specified temperature before and after warm bath test in a sealed state are set to below specified percentages and an inversion angle after the test is set to above a specified angle. CONSTITUTION: When a saturated polyester bottle is filled with a carbon dioxide beverage of 2.5 gas volume at 23 deg.C and tested by warm bath test being dipped in a warm bath of 70 deg.C in a sealed state for an hour, the following condition is to be satisfied. That is, a changing rate of dimension of the bottle filled with the carbon dioxide beverage in the direction of height before and after the warm bath test is 5% or below and a changing rate of dimension in the direction of barrel diameter is 5% or below. An inversion angle of the bottle after the warm bath test is 10 deg. or above. The crystallization degree of this saturated polyester bottle is 25-60% at the neck (mouth, mouth cock) and 25-60% at the barrel center, and preferably 25-60% at the central part of the bottom.
