Abstract

(57) [Summary] [Problem] The present invention has a gap around the pen tip and makes it impossible to write on the marking pen of a container with an ink absorbing body when the ink becomes low or the ink is faded. The present invention provides a refillable (recyclable) refill set of marking pen ink by simply and easily refilling the same pen with the same ink. A small-diameter portion of a marking pen with a cap removed in a configuration including a marking pen having a gap around a pen tip and containing an ink occluding body with reduced ink and a replenishing container or a replenishing cylinder. Then, the replenishing container or the replenishing cylinder is closely fitted to replenish the ink.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to the replenishment and refilling of oil-based and water-based marking pens.Specifically, oil-based and water-based marking pens can be used when the amount of ink is low or when the ink is faded and writing becomes impossible. It relates to a refillable (recyclable) ink refill set for marking pens, but it can also be used to fill empty containers for the production of marking pens with built-in ink occluding bodies.

[0002]

[Prior art]

 Among the conventional marking pens of various structures (which will be described below with reference to embodiments of the present invention), for example, a small-diameter portion (4a) of a so-called neck or holder (4) for fixing a pen tip, and a circular opening at the mouth portion. A nib (1a) made of synthetic resin-processed wool felt or synthetic fiber and having a rectangular cross section inserted and fixed (FIG. 1); a nib holder (4); and a container (2) containing an ink occluding body (2). 3) screwed into the opening (hereinafter abbreviated as screw-in type),

[0003] The container small diameter portion (3a) has a plurality of projections inside the mouth and (or via a nib holder (8)) a circular cross section made of synthetic fiber made of synthetic resin. The pen tip (1b) has a ventilation hole (9a.9b; FIGS. 5 and 6) around the inside where the pen tip (1b) is tightly fitted and fixed, and the ink occluding body (2) is built in the container (3). There is a type in which a tail plug (7) is closely fitted or adhered to the rear opening (3b) (hereinafter referred to as a tail plug type).

[0004] A known ink pen refilling device 9 for supplying ink to a felt pen disclosed in Japanese Utility Model Publication No. 55-14549 has a head 3 of a felt pen as shown in FIG. The ink liquid 10 in the replenisher 9 is gradually sucked up by the capillar 6 in the felt pen through the pen tip 6 adhered to the replenishing material 16 by capillary action. Ink is supplied to the felt pen.

[0005]

[Problems to be solved by the invention]

 The known ink refill for felt pens has a replenishing material made of an ink liquid absorbing material such as a fibrous body or a sponge body at the tip in an ink container, a flange on an upper part, and an expanding tapered guide. The replenisher has a structure in which the cylinders are tightly fitted. The replenisher has a large number of parts, and since it has a complicated structure with airtightness at each joint, manufacturing costs including assembly work are high, and furthermore, consumers have a high cost. The ink supply operation is troublesome, and the ink supply container is located below the pen tip, so that the ink supply time from the supply ink container due to the capillary phenomenon is long.

[0006] The refill set of the marking pen ink of the present invention solves the above-mentioned known disadvantages. In other words, the structure is simple and the manufacturing cost is low, and the replenishment work by the consumer is simple and easy, and the refill can be performed without soiling the containers and hands at that time. An object of the present invention is to provide a refill set of ink for a marking pen, which has various effects such that replenishment can be performed promptly and an appropriate amount can be replenished.

[0007]

[Means for Solving the Problems]

 A pen in which an ink occluding body (2) is built in a pen container (3), and which is inserted and fixed to a small diameter portion (3a, 4a) of the container (3) directly or via a pen tip holder (8). A transparent or translucent resilient refill container (5a) containing a refill ink (6) and a marking pen (10) having a vent (9.9a.9b) around the tip (1a.1b). Alternatively, in the configuration including the refill cylinder (5b), the refill container (5a) or the refill cylinder (5b) is closely fitted to the small-diameter portion (3a.4a) of the pen container (3), and ink is applied to the marking pen. It is a set to refill.

[0008]

[Operation]

 Referring to FIG. 3 of one embodiment, an ink occluding body (2) is contained in a container (3), and a tail plug (7) is tightly fitted in an opening (3b) at the rear of the container. A nib holder (8) having a shape in which a vent (9b) is formed on the outside is tightly fitted inside the mouth of the small diameter portion (3a) of the container, and the nib holder (8) has a circular cross section. In the case of a tail-plug type container in which the pen tip (1b) is inserted and supported, the replenishing cylinder (5b) having a transparent or translucent elasticity on the outer periphery of the small diameter portion (3a) is provided. And a suitable amount of ink is injected from the upper end of the refill cylinder (5b). (The appropriate amount is about half of the ink initially impregnated with the ink occluding body in the marking pen.) Then, the injected ink is absorbed from the pen tip (1b) into the ink occluding body (2). In the state, air is bubbled into the ink layer in the replenishing cylinder (5b) and it is seen that the air rises and is discharged one after another because the air corresponding to the amount of ink to be injected is filled with the pen tip (1b) and the ink occluding material ( 2), a part of the air in the container (3) is replaced at the same time as the ink is absorbed into the ink occluding body (2), and the discharged air is replenished through the ventilation holes (9b) around the pen tip (1b). It is considered that the ink layer in the cylinder (5b) is bubbled up and discharged one after another. As a result, the entire amount of the ink in the replenishing cylinder (5b) is absorbed and injected into the ink occluding body (2), and the replenishment of the ink is completed.

[0009]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to FIG. The pen container (3) is made of, for example, glass, metal, synthetic resin, or the like, and has an ink occluding body (2) built therein, and a small-diameter portion (4a) at the tip of the container. A pen point holder (4) into which a pen point (1a) having a rectangular cross section is inserted is screwed into the mouth. In a state where the pen is used for writing and the ink container (3) has little ink in the ink occluding body (2), for example, on the outer periphery of the small diameter portion (4a) of the pen container into which the pen tip (1a) is inserted, for example, When a refillable container (5a) made of polyethylene, acrylic, nylon, vinyl chloride, Teflon, or the like, which is ink-resistant and transparent or translucent and has elasticity, is closely fitted to the outer periphery of the small diameter portion (4a) of the container. The ink is immediately absorbed by the pen tip and the ink occluding body (2), and the replenishment of the ink is completed. It is preferable that a scale is provided in the replenishing container (5a) or the replenishing cylinder (5b) so that the injection amount can be known.

[0010]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects.

Since the configuration is simple, the manufacturing cost is low.

[0012] The replenishment work of the user is simple and easy, the replenishment can be performed without soiling the container or the hand, and the ink is injected from the upper part of the pen tip, so that the replenishment is performed promptly and any appropriate amount of replenishment is performed. It is an object of the present invention to provide an ink replenishment set for a marking pen that has various effects, such as being able to.

The present invention provides a set of a marking pen and a refill container or a refill cylinder including a marking pen having a structure other than the above.
