REFILLABLE DISPENSING SYSTEMS AND COMPONENTS

摘要

A closed-loop refillable dispensing system may include one or more reusable or refillable product packages configured to dock with an automated filling station. The automated filling station automatically mixes concentrated chemical product with a diluent and dispenses the resulting chemical product solution. The product package may include a fitment insert configured to mate with a docking connector at the automated filling station. When the product package is removed from the docking connector, the fitment insert provides a positive, leak-proof seal for the product package.
