Reinforced double-layer buffer corner protector and reinforcing method thereof

Abstract

A reinforced double-layer buffer corner protector and a reinforcing method thereof comprises a corner protector body, wherein the corner protector body comprises an inner side wall, an outer side wall, and a cavity arranged between the inner side wall and the outer side wall; a plurality of crisscrossing grooves are provided on both the inner side wall and the outer side wall; the grooves are segmented and arched deeper toward the cavity direction; the grooves are deepest at intersection points of two adjacent segments, intersection points of the grooves on the inner side wall and the outer side wall correspond in position and are connected to each other, forming support points; the plurality of crisscrossing grooves are connected together inside the cavity, forming a skeleton-like structure, which can create void spaces to meet the requirement of the blow molding process for allowing gas to flow smoothly inside the parison.
