笔帽

笔帽 (bǐ mào) refers to a cap or cover designed for the nib of a pen, primarily to protect it.

Material

Pen caps are commonly made from:

• Plastic: The most prevalent material due to its affordability, lightweight nature, and versatility in color and design. Common plastics include polypropylene (PP), polystyrene (PS), and acrylonitrile butadiene styrene (ABS).
• Metal: Often used in higher-end pens for durability, aesthetic appeal, and a premium feel. Common metals include stainless steel, brass, and aluminum.
• Wood: Occasionally used in specialized or decorative pens, providing a unique look and tactile experience.
• Other materials: Occasionally incorporating materials like resin or rubber for specific features (e.g., sealing).

Purpose

• Nib Protection: The primary function is to shield the pen nib from damage, drying out, and contamination.
• Ink Preservation: Sealing the nib prevents ink from evaporating, especially in pens not used frequently.
• Preventing Leaks: Caps help contain ink within the pen body, avoiding unwanted spills and stains.
• Protection of Surfaces: Prevents the nib from scratching or damaging surfaces when the pen is not in use.

Function

• Sealing: Many caps are designed to create an airtight or near-airtight seal, crucial for preventing ink evaporation. This is often achieved through a tight-fitting design or the inclusion of a gasket.
• Posting: Some pen caps are designed to be “posted” – securely attached to the end of the pen barrel while writing, providing balance and comfort.
• Protection during transport: Caps protect the pen from damage during carrying in pockets, bags, or pen cases.

Usage Scenarios

• Everyday writing: Used routinely with fountain pens, rollerball pens, ballpoint pens, and gel pens.
• Professional settings: Essential for maintaining the quality and functionality of pens used in offices, schools, and artistic applications.
• Art and calligraphy: Protecting delicate nibs during transport and storage.
• Collectible pens: Preserving the condition of valuable or antique pens.

Common Types

• Snap-on caps: The most common type, featuring a simple snap-fit mechanism.
• Screw-on caps: Provide a more secure seal and are often found on higher-end pens.
• Cap with clip: Incorporates a clip for convenient attachment to pockets or notebooks.
• Cap with gasket: Features a rubber or silicone gasket for an improved airtight seal.
• Cap with inner cap: Contains an additional inner cap to further protect the nib and prevent ink leakage.
• Retractable caps: Integrated into the pen mechanism, eliminating the need for a separate cap. (e.g. click pens).
