| Designed for Viscous Products | It has a wider intake tube and internal mechanism to smoothly draw up and dispense thicker formulations that wouldn't work with a standard, thin liquid pump. |
| Lotion-Style Actuator | The pump head is typically flat and broad (often called a "lotus" or "mushroom" head) with a large opening underneath it. You press down with your finger or palm, and the product dispenses around the sides of the actuator. |
| Material | The pump is usually made of polypropylene (PP) or polyethylene (PE), with seals and gaskets to ensure it is leak-proof. The exterior head can be customized. |
| Closure | It almost always comes with a twist-and-lock mechanism. You turn the pump head a quarter-turn to lock it for travel, preventing accidental discharge. |
| Travel-Safe | The lock mechanism is crucial for preventing messy leaks in luggage. |
