。In order to improve the heat resistance of the spout, which requires tight sealing, we have taken measures such as crystallizing and whitening only the spout that is not stretched, and making the entire bottle a multilayer structure that includes a heat-resistant resin layer. A heat-resistant blow bottle was supplied.

あった。(Problems to be Solved by the Invention) The above-mentioned conventional heat-resistant blow bottle with a whitened spout requires a lot of processing time, has a white appearance and poor transparency, and has a multilayer structure including a heat-resistant resin layer. The problem with this method is that it is expensive because it uses a large amount of expensive heat-resistant resin.
（課題を解決するための手段） 以下、添付した図面に基づき説明する。(Means for solving problems) The following description will be made based on the attached drawings.
第１図は本発明の耐熱ブローボトルの一例を示す正面断
面図であり、第２図は第１図の耐熱ブローボトルを製造

る耐熱ブローボトルである。In the present invention, the body part 1 has a single layer structure of polyethylene terephthalate resin, the outer layer 3 and the inner layer 4 of the spout part 2 are polyethylene terephthalate resin, and the intermediate layer 5 is made of semi-aromatic amorphous polyamide. This heat-resistant blow bottle has a laminated structure made of resin, and is characterized in that the body portion 1 is oriented and crystallized.

位を主体とし、その物性を損わない範囲で他の共重合成
分を少量含有する共重合体であってもよい。In the present invention, it is used throughout the entire thickness of the body part 1,
The polyethylene terephthalate resin used for the outer R3 and inner layer 4 of the spout part 2 is a copolymer mainly composed of ethylene terephthalate repeating units and containing a small amount of other copolymer components within the range that does not impair its physical properties. Good too.

ある。In the present invention, the semi-aromatic amorphous polyamide resin used for the middle R5 of the plug portion 2 has an amine component such as an aliphatic diamine such as hexamethylene diamine, and an acid component such as isophthalic acid, terephthalic acid, or a mixture thereof. It is a polyamide copolymerized as an aromatic dicarboxylic acid.

るので、口栓部のポリエチレンテレフタレート系樹脂を
よく補強して耐熱性を高めることができる。Since both the outer layer 3 and the inner layer 4 of the spout portion 2 are made of polyethylene terephthalate resin, it has excellent transparency and hygiene. This part is not stretched and tends to whiten due to crystallization, so in order to maintain transparency, the degree of crystallinity must be 1.347 g/c.
It is preferable to keep it below m3. In addition, the intermediate R5 is made of semi-aromatic amorphous polyamide resin that has excellent heat resistance, transparency, and compatibility with polyethylene terephthalate resin, so the polyethylene terephthalate resin in the spout part can be well reinforced to increase heat resistance. I can do it.
なおこの中間層５は延伸度合の少ない肩部２１まで伸ば
してもよい、そしてこの中間Ｍ５の厚さとしては、全体
の厚さの５〜９０％とするのが好ましい。Note that this intermediate layer 5 may be extended to the shoulder portion 21 where the degree of stretching is low, and the thickness of this intermediate layer M5 is preferably 5 to 90% of the total thickness.

結晶化度を高めても透明性が良好に保たれるので好まし
い。The body part 1 has a single layer structure of polyethylene terephthalate resin, so it has excellent stretchability, and since it is oriented and crystallized, it has excellent heat resistance. The degree of crystallization is determined by the density of 1.37
If it is set to 58/cm3 or more, the heat resistance will be even better. If the stretching ratio is set so that the area is 6 times or more,
This is preferable because transparency can be maintained well even if the degree of crystallinity is increased.
延伸度合が少なく、耐熱性の劣る底部６も、口栓部と同
様このｍ層構造として熱による変形を防止してもよい。The bottom portion 6, which has a low degree of stretching and poor heat resistance, may also have this m-layer structure to prevent deformation due to heat, similar to the spout portion.

。To manufacture the heat-resistant blow bottle of the present invention, first, a test tube-shaped parison is made using an injection molding apparatus as shown in FIG. Oriented crystallization may be performed to, for example, make the degree of crystallinity to a density of 1.375 g/cm 3 or more.

共射出して底部６の３屑の積層構造を形成する。That is, first, a polyethylene terephthalate resin 11 and then a semi-aromatic amorphous polyamide resin 51 are co-injected from an injection nozzle 8 into a cavity surrounded by a split mold 7 and a core mold 71 to form, for example, three layers of the spout part 2. Then, the semi-aromatic amorphous polyamide resin 51 is stopped and the polyethylene terephthalate resin 1 is formed.
1 is injected to form a single layer structure of the body part 1. Furthermore, the semi-aromatic amorphous polyamide resin 51 is again co-injected to form the laminate structure of the three pieces of the bottom part 6.

The present invention is carried out by blow-stretching to an area magnification of 6 to 14 times in a heating mold heated to 40°C or less, holding it for a predetermined period of time for heat treatment, and cooling the mold or by blowing a refrigerant into the bottle. A heat-resistant blow bottle is obtained.

The obtained intermediate is transferred into a final mold having an internal volume ratio of 75 to 115% with respect to the heating mold and re-stretched, thereby efficiently cooling the final mold to obtain the heat-resistant blow bottle of the present invention.
