Abstract

An object of the present invention is to provide a molding device for heat-resistant containers which uses existing molding devices and which can manufacture relatively inexpensive PET resin heat-resistant containers. The thermoforming device includes: a mounting station (210) configured to fit a positioning pin into an opening in the neck portion of the primary blow molding (20) by lifting a table (211), and by gripping The unit grips the outer periphery of the neck portion to mount the primary blow molding on a conveying unit (250) arranged to be linearly movable; a heat treatment station (220) configured to pass the primary blow molding The molding (30) is heat-treated and shaped to obtain an intermediate molding; a final blow molding station (230) configured to obtain a heat-resistant container (10) having a predetermined shape by performing final blow molding on the intermediate molding ); and a collection station (240) configured to collect the heat-resistant container (10) by removing the heat-resistant container (10) from the conveying unit (250).

Description

technical field

[0001] The present invention relates to a thermoforming device for heat-resistant containers, which is constructed as: Obtained by one blow molding of a preform made of polyethylene terephthalate (PET) resin The primary blow molded parts are heat-treated and formed to form a heat-resistant container. Background technique

[0002] Conventionally, for example, heat-resistant containers having heat resistance have been adopted as returnable containers for mineral water and the like. Returnable containers for mineral water and the like are generally recovered from consumers after being used and washed by washing liquid heated to a temperature of approximately 65°C (hot water washing). In this way, returnable containers can be reused many times. For this reason, heat-resistant containers made of polycarbonate resin or the like having high heat resistance are suitably used as returnable containers. Meanwhile, as a returnable container for mineral water, for exam...

Embodiment Construction

[0060] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0061] figure 1 The heat-resistant container 10 shown in is formed of polyethylene terephthalate (PET) resin and is used, for example, as a container with about 3 to 5 gallons (about 12 to 20 liters) for mineral water. Recycle the bottle. The heat-resistant container 10 as a large recyclable container includes: a neck portion 12 having, for example, an outer diameter of about 40 mm to 60 mm and including an opening 11 at an upper end; a cylindrical body portion 13 having, for example, about 270 mm to 300 mm shoulder portion 14, which connects neck portion 12 and body portion 13 and gradually expands from neck portion 12; bottom portion 15, which seals one end of body portion 13; and heel portion 16, which connects body portion 13 with bottom part 15.

[0062] The main body portion 13 is formed with a reinforcing portion 18 constituted by a plurality of a...
