However, the heat-resistant resin that has good adhesion to the polyethylene terephthalate used to form the heat-resistant mouth member of the container has a heat resistance temperature of about 85°C, 92 to 95°C, even if it is polyarylate, which has the highest heat resistance. ℃
When filling fruit juice drinks etc. that have been heat sterilized with
Its heat resistance cannot be said to be sufficient. Therefore, a heat-resistant container using a heat-resistant mouth member made of polycarbonate, which has better heat resistance than polyarylate, has been considered. However, polycarbonate and polyethylene terephthalate have poor adhesion, and when a mixture of polycarbonate and polyethylene terephthalate is used, the two have poor compatibility, so they do not mix, resulting in whitening or granular formation. There is.

The present invention has been made to solve the above-mentioned problems, and provides a heat-resistant container in which a heat-resistant mouth member is fixed to the outside of the mouth and neck of a container body made of polyethylene terephthalate, the heat-resistant mouth member comprising:
This is a heat-resistant container characterized by being made of a mixture of 40 to 80 parts by weight of polycarbonate and 60 to 20 parts by weight of polyester consisting of terephthalic acid, ethylene glycol, and cyclohexanedimethanol.
次に本考案を実施例を用いて詳細に説明する。 Next, the present invention will be explained in detail using examples.

Consisting of The container body 1 includes a bottom, a body, a shoulder,
It consists of a mouth and neck part 1a and is molded from polyethylene terephthalate. The heat-resistant mouth member 2 is fixed to the outside of the mouth and neck portion 1a of the container body 1. Specifically, the injection-molded heat-resistant mouth member 2 is inserted and fixed in a mold in advance, and the container is Main body 1
At the same time, the two are integrated.

約95℃である。 The heat-resistant mouth member 2 is made of a mixture of 40 to 80 parts by weight of polycarbonate having excellent heat resistance and 60 to 20 parts by weight of polyester consisting of terephthalic acid, ethylene glycol, and cyclohexanedimethanol. Here, if the proportion of polycarbonate is less than 40 parts by weight, the heat resistance will be insufficient, and if it exceeds 80 parts by weight, the proportion of polyester will be less than 20 parts by weight, and the adhesion with the mouth and neck of the container body made of polyethylene terephthalate will be reduced. Sexuality becomes worse. Therefore, in order to obtain both heat resistance and adhesiveness, they are mixed in the proportions within the above range. The polyester is suitable for both extrusion molding and injection molding, has a high melt viscosity relative to its intrinsic viscosity (average molecular weight), and can be subjected to various extrusion moldings (film, sheet, irregular shape, coextrusion).
In addition, it has good adhesion to polyethylene terephthalate, is compatible with polycarbonate, and has excellent physical properties such as impact strength and tensile strength. moreover,
The chemical resistance of polycarbonate is also improved and the cost efficiency is also improved. The heat-resistant spout member 2 made of a mixture of such polyester and polycarbonate in the above-mentioned ratio has transparency and is transparent to the container body 1.
It has good adhesion to the mouth and neck part 1a, and its heat resistant temperature is:
The temperature is approximately 95℃.
