Description

TECHNICAL FIELD

[0001] The utility model relates to the field of stationery, in particular to a scented pen. BACKGROUND

[0002] As a common writing tool, pens are widely used in daily life. Common types include fountain pens, brush pens, ballpoint pens, and pencils. With the development of the times, in addition to being used as a writing tool, some special pens are also given specific functions and values, such as decorative purposes, collectible value, or as a means for users to express their personality. For example, many users have certain requirements for signature pens. In addition to meeting the needs of smooth and comfortable writing, they also need to meet certain aesthetic and distinctive features.

[0003] Existing signature pens are generally divided into two types: those with a ballpoint tip and those with a fiber tip. They are also divided into two types: water-based signature pens and oil-based signature pens, depending on the type of ink used. Generally speaking, the ink in many signature pens does not need to be filled throughout the length of the pen body. A length of 1 to 2 centimeters is sufficient to meet the needs of use. Therefore, the pen body of many existing signature pens is lengthened only to meet the needs of the user's grip. In fact, only about 5 centimeters of the pen tip, tip sleeve, and refill are needed for writing. The rest of the pen body is designed to meet the needs of the user's grip.

[0004] Therefore, the individualized design of many signature pens is focused on the lengthened pen body, such as printing special labels, using special materials, and setting special pen holders. In addition, some signature pens also have the function of adding scented pens to enrich the functionality of the pen. For example, the Chinese utility model patent with patent number CN209794972U discloses a new type of spice pen. The new type of spice pen includes a body, a spice bin, a spice stick, a pen holder, and a pen cap. The pen cap is placed on the top of the body. The spice bin is a hollow cavity inside the pen cap. The spice stick is placed inside the spice bin, allowing the new type of spice pen to release a scent. It can be used as a pen and as a space to hold the scent, allowing people to use the pen while also benefiting from the invigorating effect of the scent released by the plant spice. However, the design of the new type of spice pen is to specially install a spice bin on the top of the pen, resulting in a heavy weight on the top of the pen. This can affect the user's experience and writing performance when writing. UTILITY MODEL CONTENTS
