It is a cylindrical container, typically made of PP (Polypropylene) or PE (Polyethylene), consisting of two main parts:

1. The Sleeve/Body: The outer tube that holds the product.

2. The Screw Mechanism: An internal plunger that, when twisted, pushes a platform up to dispense the product.

Unlike a squeeze tube, it offers precise, controlled application and prevents product from being sucked back in.

Key Components

1. Cap: Snaps or screws on to cover the applicator and prevent drying or contamination.

2. Applicator: Attached to the cap. Common types include:

   • Doe-Foot Applicator: A soft, paddle-shaped tip made of porous plastic or silicone. Ideal for smooth, even application of gloss.

   • Brush Applicator: A small, cylindrical brush for more precise application, often used for liquid lipsticks.

   • Slant-Tip Applicator: A solid plastic tip with an angled surface for direct application.

3. Shoulder/Neck: The part of the tube that the cap seals against. It has an opening from which the product is dispensed.

4. Sleeve/Body: The main container that holds the product.

5. Twist Knob (Base): The part at the bottom the user turns to raise the product.

6. Platform (Piston): The internal disc that moves up the tube when the knob is turned, pushing the product out.

7. Cup (or Ferrule): The small plastic piece that holds the applicator and snaps into the cap.
