る。(Prior Art) The barrel of a writing instrument that houses a batting filled with ink must have excellent gas barrier properties in order to suppress volatilization of the ink. Therefore, most of the barrels of conventional writing instruments of this kind have been made of materials with excellent gas barrier properties such as plastic, metals such as aluminum and steel, or glass. However, barrels made of such materials have the following problems. first,
A single plastic barrel cannot be used because the xylene or toluene in the oil-based ink penetrates into the plastic, causing it to swell and deform. Also,
Although barrels made of metal or glass do not have such restrictions, metals have plasticity, so during mass transportation, external shocks and contact between individual writing instruments can cause unevenness and scratches, reducing the product value. This results in a decrease in Furthermore, glass barrels are heavy, which increases transportation costs and causes breakage.
In addition, there are design constraints because it is difficult to print various colors on the glass itself, and labels must be pasted in a separate process, leading to a rise in manufacturing costs.

The thickness, number of layers, etc. are free. For example, in order to improve the ink volatilization prevention effect, that is, to improve gas barrier properties and water resistance, the thickness of the aluminum vapor deposited layer 5 may be increased, and the PE layer 4, It is also possible to change 7 to a PET layer or a PP layer (polypropylene layer). Also,
The type of paper is not limited to the above-mentioned liner papers 3b and 3c; for example, it is also possible to use specially treated paper with excellent waterproof properties.
尚、先軸９の表面にもガスバリアー性を向上さ
