Plastic vessel and preparation process thereof

Abstract

The invention relates to a plastic vessel and a preparation process thereof. The plastic vessel comprises a barrel body, wherein the external circumference of the top surface of the barrel body is provided with a supporting conveying ring; the circumference of the barrel body is provided with two annular ribs. The plastic vessel is characterized in that the supporting conveying ring and the barrel body are of a split structure; the barrel body is formed by stretching the supporting conveying ring in a hot state and combining and tightening the supporting conveying ring with the top surface of the barrel body; the external circumference in the top surface area of the barrel body is provided with an annular groove; correspondingly, the internal circumference of the supporting conveying ring is provided with an annular convex body which is matched with the annular groove; the supporting conveying ring is inlaid and tightened at the external circumference of the top surface of the barrel body. The plastic vessel and preparation process has the advantages that the supporting conveying ring and the barrel body of the plastic vessel are of the split structure, the barrel wall of the barrel body is uniform, the material consumption is low and the material cost is reduced; furthermore, the preparation process of the plastic vessel is simple, so that the equipment investment cost and the material cost are lowered.

Description

technical field [0001] The invention relates to a plastic container, in particular to a plastic container and a preparation process thereof. Background technique [0002] L-Ring Drum (L—Ring Drum) is a large-scale plastic drum whose overall shape is cylindrical. At the top or top and bottom ends of this type of drum, there is a supporting and carrying ring that is integrally formed with the drum body in one step and has a solid cross section. , named because the cross-sectional shape of the supporting transport ring resembles the English letter L in its first-generation product. The development of large plastic barrels began with the industrial production of high molecular weight high density polyethylene (HMwHDPE) resin in the 1960s. The ultra-high impact strength and melt strength of HMwHDPE resin make it possible to produce large plastic barrels that can meet the international packaging requirements for dangerous goods transportation. In 1977, the German Mauser Comp...

AI Technical Summary

Problems solved by technology

[0008] The disadvantages of the plastic barrel in the above patent are: since the barrel body and the supporting transport ring are prefabricated into parts and then combined by welding or bonding, the process is complicated and the production efficiency is low, and when loading and unloading the fully loaded plastic barrel We will find the problem of weak combination
