Definitions
- the present invention relates to a pen core for a writing instrument having flexibility, and in particular, to a pen core for a writing instrument having flexibility.
- a brush or a brush brush made of synthetic fibers called a tapered steel with a sharpened tip has characteristics similar to those of a natural brush. However, since the constituent material at the tip of the latter was merely replaced with synthetic fiber,
- a relay fiber core for guiding and reinforcing the ink into a cavity of the cap-shaped member.
- the tip is easily torn off.
- a pen core formed with an elastic core made of a slit-like capillary tube or an extruded core made of a soft thermoplastic synthetic resin in a pointed mirror shape is similar to a brush. It has the advantage of writing a spelled typeface, but the brush is stiff and has a capillary structure.
- Japanese Utility Model Publication No. 55-38,691 discloses that irregularly entangled fiber surfaces and entangled points are covered with an elastic resin such as polyurethane. Further, a vane core in which the core body thus obtained is formed into a sharp shape by combining the core body is disclosed.
- the vane core having such a structure is similar to the pen core made of the foam-like material of [C] above at the sharp end of the elastic fiber core having the felt-like structure. Although it has a relatively good resilience to E, it is extremely weak against tensile stress and bending stress accompanied by abrasion, and it is easy to cause fraying and tearing at the tip.
- An object of the present invention is to combine a commercially available synthetic fiber and a synthetic resin elastomer to form a specific fibrous structure as a rubber-like fibrous body. Better aligned in the longitudinal direction
- Another object of the present invention is to play on the ground surface of the writing tip.

- the vane core 20 according to the present invention should be in communication with the reservoir 13.
- the rear end is pushed into the reservoir 13, and the front end is arranged so as to protrude to the outside of the main body 11 through the opening of the front end of the main body 11.
- the pen core 20 has an appropriate thickness (single yarn strength), and is arranged in a vertically aligned manner.
- a porous rod-shaped body formed by a large number of crimped polyamide fibers 21 and a resin resin 22 described later in detail.
- the core 20 is provided with a composite fiber structure as a rubber-like elastic material.
- the fiber 21 is a nucleus component, and has a thickness in the range of 1Z2 to: LZ30, preferably 1/5 to: LZ20 with respect to the diameter of the polyamid ⁇ f21.
- Do that fin key conduits that are arranged in earthenware pots by and ing the aggregation state run-dam in uniform with the remaining It has a property that the shape of the core body 20 is extended from one end to the other end of the core body 20 while changing the shape to random. It is formed to have an appropriate porosity in the range of 0%.
- a core having such a configuration is formed to have a diameter of, for example, 10 or less, and one end 25 thereof is processed as a writing tip by grinding or the like.
- synthetic resin 'elastomer' in the above-mentioned constitution various compounds can be prepared, and in particular, an isocyanate group and an active hydrogen group are available.
- Polyurethane-based elastomers, which are the reaction products of the above, are preferred because they excel in water resistance, chemical resistance and abrasion resistance.
- the synthetic resin elastomer that forms the composite layer with the vertically oriented fiber as the core component is the physical characteristic.
- the balance in other words, one with sufficiently high tensile strength and distress should be used. That is, for example, if the tensile strength of the synthetic ⁇ gf elastomer is high, but the elongation is insufficient, a stress exceeding the tensile strength may be generated. Residual and permanent set
- OMPI 1 other than fatigue is that Ji Do rather easy raw, synthetic resin e la be sampled Ma that written can not be said to be appropriate.
- the synthetic resin elastomer used in the above-mentioned specific composition was measured in accordance with a test method specified in JIS. It must have an elongation of at least 200% and an elastic modulus (so-called modulus) of 100 kg / cm 2 or less at 100% elongation. also of it is confirmed and Ru suitable der this that Yusuke Oh and this Ru of, a et al beauty to of put that 20 ⁇ 6 0 3 ⁇ 4 cm 2 to ⁇ and 100% elongation of 250% or more and an elastic modulus Was.
- a synthetic S- resin 22 that satisfies the above conditions and forms a composite structure as a rubber-like elastic body in cooperation with the polyamide steel 21 Is a reactive or non-reactive thermoplastic or thermoset polyester elastomer material that is commonly used for various applications. You can arbitrarily select from these.
- Such elastomer materials include Colon Z Nipporan (Polyurethane Co., Ltd. Japan), bread odex (Dainippon Ind.) Pearls), adiprene L (dupont), brucholan (bielle), and the like.
- the synthetic resin elastomer 22 having the above-mentioned characteristics is provided on one or more of the polyamide fibers 21 outside the longitudinal direction thereof.
- OMP1 wipo A composite layer extending along one direction is formed at random. Accordingly, the pen core according to the present invention is bent, twisted, shrunk and pulled, etc. Interface between the synthetic resin elastomer 22 and the polyamid fiber 21 as the nucleus during the deformation due to the stress change
- the elastic strain energy generated in Fig. 5 is advocated as a reaction, so it is excellent in deformation recovery. That is, since the writing tip 25 of the vane core 20 has the substantive property that the writing tip 25 normally extends in parallel with the vertical line of the composite fiber, A flexible brush sensitivity is obtained that responds to changes in the angle and direction of the brush stroke and responds well to the paper surface by responding quickly to deformation and 10- dimensional response.
- the brush sensitivity of the vane core 20 made of l oLi trr is based on the type of fiber 21 as the core component, the degree of presence and absence of crimping, and the porosity of the core body. Etc. can vary over a wide range.
- the reason for using a polymer woven fiber as the fiber 21 in the present invention is that it has an amide bond similar to that of animal ⁇ ⁇ in its molecular structure. It has relatively high hygroscopicity or water-absorbing properties in fibers, and is capable of utilizing fibers that swell and reduce rigidity when absorbing water.
- the crimp applied to the fiber also contributes effectively to the deformation response at the writing tip 25.
- the crimping not only promotes the intertwining and the formation of voids inside the pen core 20, but also the complex under a certain cohesion state
- the fibrous tissue can be given a certain degree of deformation freedom, thereby improving the deformation response of the writing tip.
- the porosity of the pen core becomes smaller, the ink becomes more inexpensive. As the flow decreases and the brush becomes thinner, the free bending and elongation of the composite steel structure is hindered, and the degree of local or global deformation of the writing tip in response to changes in the brush EE Tends to decrease. On the other hand, if the porosity of the vane core is too large,
- each fiber is easily frayed.
- the porosity should be within the range of 35 to 70% in order to obtain a vane core having desired brush sensitivity and writing characteristics. However, it was confirmed that it is preferable to set the porosity in the range of 40 to 60% when the processing conditions, assembly conditions, etc. are taken into consideration.
- the vane core according to the present invention has an excellent restoration characteristic against deformation.
- the graph in Fig. 5 shows various vanes with a length of 70 dew for 30 seconds.
- the curve ⁇ ⁇ represents the restoration characteristic of the pen core according to the present invention with a porosity of 48%
- the curve B represents the S-line A, which is more synthetic resin than the vane core.
- Curve C shows that the pen core of curve A is a core component more than the pen core of curve A, in which the thickness of the core is increased and the porosity is 43%.
- the graph shows the restoration characteristics of the pen core according to the present invention, in which the fiber is increased by 20% and the thickness of the synthetic resin elastomer is reduced to a porosity of 44%. You. On the other hand, the track ⁇ D is replaced by
- Curve E shows the restoring characteristics of a vane core with a porosity of about 45% using 20% fiber, and curve E shows the restoring characteristics of a similar vane core with a polyester fiber. Each is represented.
- the vane core 20 according to the present invention which has been described above, is i
- the flexible longitudinal direction of the fine polyamide fiber 21 and the deformation response ⁇ to external stress ⁇ indicate the elasticity and elasticity of the synthetic resin elastomer 22. It is extremely flexible, based on its resilience and its complement to each other.
- the pen 3 core 20 has an ink conduction path 24 with a vertically elongated direction inside, and a porous structure with a large porosity that can absorb and hold a large amount of ink. As a result, it is possible to obtain an ink outflow characteristic having a sufficient followability to changes in writing speed and handwriting width during writing.
- individual composite fibers have good resilience.
- the pen core according to the present invention has a good brush feel and writing characteristics of handwriting as well as the tip of a conventional brush or paintbrush, and has excellent softness. Utilizes flexibility to cover a wide range, such as for calligraphy and sketching
- the pen core according to the present invention is formed by a known process described in, for example, U.S. Pat. Nos. 3,864,183 and 3,558,392. After continuous forming, the tip is ground, making it easier and therefore more economical with higher productivity.
- the wick 20 'shown in Fig. 6 has the writing tip 25' formed in the same shape as the tip of the brush, and is particularly suitable for calligraphy.
- FIG. 7 shows a pen core 20 having a writing tip 25 * formed in a chisel shape and suitable for calligraphy.
- the rear end of the vane core located on the right side of each is ground into a frustoconical shape so that it can communicate with the reservoir over a wider area. ing .
