A kind of lightweight Packaging Bottle embryo bottom structure

The utility model relates to packing plastic bottle field, aims to provide a kind of lightweight Packaging Bottle embryo bottom structure.This kind of lightweight Packaging Bottle embryo bottom structure adopts at the bottom of olive, interior outside at the bottom of olive is all formed by three sections of circular arcs and is smoothly connected, first paragraph circular arc is for completing from the bottle wall thickness even variation to bottle embryo body at the bottom of bottle embryo, the bottle wall thickness of second segment circular arc and the 3rd section of circular arc is the bottle wall thickness at the bottom of bottle embryo, and the bottle wall thickness at the bottom of bottle embryo is 0.8 ~ 0.85 with the ratio of the bottle wall thickness of bottle embryo body, the bottle wall thickness of bottle embryo body is consistent.The utility model, by the shape bottom change bottle embryo, improves the plastics distribution of bottle, and is conducive to the adjustment of blowing technology, again reduce weight simultaneously, save raw MAT'L, reduce the packing cost of product.
