Latest Patents

One of Nohara's latest patents is for the preparation of multi-layer drawn polyester bottles. This innovative bottle design features a neck portion with an opening at the top and a fitted or screwed part on the periphery. The bottom portion is formed by fusion bonding and closing of a pipe, while the barrel portion is biaxially molecularly oriented through draw-blowing of the pipe. The pipe is composed of a co-extrudate of inner and outer surface base layers of polyethylene terephthalate and an intermediate layer of an ethylene-vinyl alcohol copolymer. This multi-layer drawn polyester bottle is prepared by co-extrusion of a multi-layer pipe, cutting the pipe to a predetermined length, and forming the neck portion through a series of heating and blow-forming processes.

Another notable patent involves an injection-molded body of olefin/vinyl alcohol copolymer. This body is created by melt-kneading a composition that includes a high-molecular-weight olefin/vinyl alcohol copolymer and a low-molecular-weight counterpart. The resulting product showcases enhanced properties due to the specific molecular weight and vinyl alcohol content, making it suitable for various applications.
