Abstract

The invention provides a hot-filled wide-mouth bottle and a processing method thereof, and the processing method of the hot-filled wide-mouth bottle comprises the following steps: feeding a PET (Polyethylene Terephthalate) raw material into an injection molding machine, and carrying out injection molding to obtain a hot-filled wide-mouth bottle blank without tooth grains at a bottle opening; the hot-filled wide-mouth bottle blank is directly subjected to high-blowing machining, the hot-filled wide-mouth bottle blank is completely placed in a high-blowing mold, and a hot-filled wide-mouth bottle rough body is obtained; and carrying out hot filling on the hot-filling wide-mouth bottle thick body to obtain the hot-filling wide-mouth bottle. Tooth grains at the bottle opening are not processed during injection molding, so that the injection molding efficiency is improved, an injection mold is simplified, and the injection molding cost is reduced; high blowing is directly carried out after injection molding, so that the crystallization step is omitted, the processing efficiency is improved, and the processing cost is reduced; the hot-filling wide-mouth bottle blank is completely placed in the high-blowing mold, the high-blowing mold and high-blowing air pressure can be utilized during high-blowing to obtain bottle opening tooth grains, and the hot-filling wide-mouth bottle is crystallized by controlling the high-blowing temperature, so that the hot-filling wide-mouth bottle is efficiently processed at low cost.

Description

technical field [0001] The invention relates to the technical field of hot-fill jars, in particular to a hot-fill jar and a processing method thereof. Background technique [0002] Jars are commonly used containers in daily work and life. According to the different types of hot and cold liquids loaded, they include cold-fill jars and hot-fill jars; for hot-fill jars, it is necessary to hold high-temperature liquids (such as Hot tea, hot sauce, etc.), in order to avoid shrinkage and deformation of hot-fill jars after contact with high-temperature liquids, it is necessary to crystallize the preform during processing, which requires separate side crystallization between injection molding and bottle blowing Processing, and then seriously affects the processing efficiency of hot-fill jars, also increases the processing cost of hot-fill jars simultaneously. [0003] Therefore, there are defects and deficiencies in the prior art, which need to be further improved and developed. ...
