Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to instruments such as writing implements and applicators, and includes a bottle containing a liquid substance such as ink that can be moved forward and backward in a barrel. When the bottle is moved forward and backward, liquid substances such as ink are supplied from the same bottle to areas such as the tip of the brush, the tip of the pen, and the tip of the brush. The cap is inserted into a recess formed at the tail end of the barrel, and in this inserted state, a pushing operation and a releasing operation of the pushing operation are applied to the cap alternately. The main feature is that the tail plug is removably fitted into the opening of the recessed part, and a recess is provided at the tail end of the bottle into which the inner end of the tail plug is removably fitted. .

[Problems that conventional techniques and ideas attempt to solve]

Conventionally, this type of writing instrument, applicator, and other instruments did not have a tail plug. For this reason, vibrations that occur during the distribution process from manufacturers to retailers often cause the bottle to move back and forth, causing ink and other liquid substances to be supplied into areas such as the tip of the brush, tip of the brush, and the cap. Not only that, but customers sometimes end up inserting caps into the recesses while they are on display for so-called trial use. In other words, there is an undesirable defect that causes an inappropriate situation in terms of product sales.

[Means for solving problems]

The present invention solves the above-mentioned defects by removably attaching a tail plug whose inner end fits into a recess provided at the tail end of the bottle to the tail end of the barrel.
