螢光筆的起源和歷史

1960- 纖維筆頭技術

螢光筆的前身可追溯到1960年代。日本發明家堀江幸夫於1964年創立了「大日本文具株式會社」(Pentel)，並開發了纖維筆頭技術，這為螢光筆的誕生奠定了基礎。

發明思路:

- 1

堀江想的是能做出一枝筆能寫起來有日文筆畫那樣的感覺，但又兼具原子筆的便利。

-2

使用壓克力纖維和樹脂製成的筆頭，兼具硬度和柔軟性，以形成細緻的筆尖並順暢吸墨。

-3

筆尖內的微小通道利用毛細作用將墨水引導至筆頭，墨水需稀薄以流通，但又需黏稠以防滲漏。筆管設有氣孔以調節內部壓力，防止漏墨。

-4

經過八年研發，這款筆因其線條扎實且書寫流暢，適合簽署重要文件，最終問世。

1963年- 美國商業化螢光筆

1963年，美國推出了第一款商業化的螢光筆Hi-Liter，這款產品迅速受到歡迎，尤其是其明亮的顏色如黃色和粉紅色，成為學習和筆記的常用工具。

Origins and History of the Highlighter

1960 - Fiber Tip Technology

The precursor to the highlighter can be traced back to the 1960s. Japanese inventor Yukio Horie founded Pentel Co., Ltd. in 1964 and developed fiber tip technology, laying the foundation for the invention of the highlighter.

Inventive Ideas:

1. Horie aimed to create a pen that provided the feel of Japanese brush strokes while also offering the convenience of a ballpoint pen.

2. The pen tip was made from acrylic fibers and resin, combining hardness and flexibility to create a fine tip that smoothly absorbed ink.

3. Tiny channels within the tip used capillary action to guide the ink to the tip. The ink needed to be thin enough to flow yet viscous enough to prevent leaking. The pen barrel was designed with an air hole to regulate internal pressure and prevent ink leaks.

4. After eight years of research and development, this pen was launched due to its solid lines and smooth writing, making it suitable for signing important documents.

   
   

1963 - Commercialization in the United States

In 1963, the first commercial highlighter, Hi-Liter, was introduced in the United States. This product quickly gained popularity, especially for its bright colors like yellow and pink, becoming a common tool for studying and note-taking.
