Prior to R&D/Leverage’s offering, rigid containers with internal threads and drain-back pour spout features were typically HDPE blow molded bottles with an injection molded PP fitment. Tooling is required for multiple components, and assembly and mixed-reins (HDPE and PP) are required, which complicate recycling efforts!Internal Thread and Drain-Back Pour Spout

R&D/Leverage’s new offering is one piece 100% PET, which has the highest recycling percentage in the US market.


The GREEN choice is a single piece, one stage injection stretch blow molded PET bottle with internal threads.
