Abstract
An all-plastic, reciprocating foam dispenser is contemplated. The dispenser relies upon a bellows that also serves as the air chamber/cylinder, thereby eliminating the need for complex valving while also reducing total plastic mass and shortening the axial profile of the dispenser. In this manner, the dispenser can be coupled to narrow-necked containers (≤40 mm diameter) and dispense large doses (≥1.2 mL). A locking collar secures the pump in a sealed, up-locked position, while also providing greater flexibility to adjust the air-to-liquid ratio to help impart the desired consistency to the dispensed foam product.
