Description

【0001】
【発明の属する技術分野】
本発明は、軸筒内にインキを吸蔵した中綿が内蔵された筆記具に関するものである。
【0002】
【従来の技術】
軸筒内にインキを吸蔵した中綿が軸筒内に収容された筆記具は、合成樹脂製の軸筒の先端開口に取り付けられたペン体の尾端部が中綿の先端部に差し込まれており、中綿に吸蔵されたインキがペン体に供給され、筆記に供される。そして、軸筒の尾端開口には同じく合成樹脂製の尾栓が取り付けられている。
【0003】
ところで最近では、環境や資源保護の観点から廃棄物を減少する必要性が大きく、このために、中綿式の筆記具においても、中綿のインキを使い切ったときに、筆記具を使い捨てにせずに、中綿を新しいものに交換し、軸筒などの部品はそのまま活用して筆記具を長く使用することが多くなった。
【0004】
【発明が解決しようとする課題】
ユーザーが新しい中綿に交換するときは、インキを使い切った中綿を軸筒から取り出す必要があるが、ペン体の後端部が中綿に差し込まれているので、ピンセットなどの治具を利用して中綿を軸筒から引き抜く必要がある。また、その際に中綿に直接手が触ることがあり、手が汚れる不都合がある。
【0005】
そこで本発明は、ユーザーが中綿を交換する際に、ピンセットのような治具を必要とせず、また、手が汚れることが少ない筆記具を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
かかる目的を達成するために、本発明は、インキを吸蔵した中綿が軸筒内に収容され、軸筒の先端開口に取り付けられたペン体の尾端部が中綿の先端部に差し込まれ、軸筒の尾端開口に尾栓が取り付けられた筆記具において、中綿の先端部を軸筒内面の案内リブで保持するとともに、中綿の尾端部が尾栓で保持し、尾栓の中綿保持力を、軸筒の案内リブの中綿保持力および中綿とペン体の接触抵抗の和よりも大きくする。
【0007】
【発明の実施の形態】
以下に、図面に基づいて本発明の実施の形態を具体的に説明する。図1において、合成樹脂で成形された軸筒10の先端はテーパー部11であり、テーパー部11の中心孔に筒状のペン体保持部15が形成されている。なお、テーパー部11は別部品の先口としてもよい。軸筒10内面の先端に複数本の案内リブ14が形成されており、同じく内面の尾端側に、内ねじ12が形成されている。
【0008】
尾栓40の内周面には複数本の中綿保持リブ45が形成され、外周面には外ねじ41が形成されており、軸筒10の内ねじ12と尾栓40の外ねじ41が螺合することにより尾栓40は軸筒10の尾端開口に取り付けられている。中綿30は、倦縮した極細繊維を引き揃えて棒状に成形されたものであり、水性インキを吸蔵している。この中綿30の前後が軸筒10の案内リブ14および尾栓40の中綿保持リブ45で保持されて軸筒10内に収容されている。ペン体20は、連続気泡を有する合成樹脂からなる棒状体であり、ペン体保持部15に保持されている。そして、ペン体20の尾端部は中綿30に差し込まれている。したがって、中綿30に吸蔵された水性インキはペン体20に供給され、筆記に供される。また、非使用時には、軸筒10にキャップ50が嵌着され、インキがペン体20から蒸発するのを防止している。
【0009】
ここで、中綿30の先端部は案内リブ14に軽く接触する程度で保持されており、尾栓40の中綿保持リブ45による中綿30の保持力は、軸筒10の案内リブ14による中綿30の保持力と中綿30に差し込まれたペン体20の中綿30との摺動抵抗との和よりもずっと大きくなっている。つまり、中綿30は尾栓40により強く保持されている。
【0010】
そして、中綿30のインキを使い切って新しい中綿30に交換する際、ユーザーは尾栓40を左回転させて軸筒10から取り外すが、尾栓40の中綿保持リブ45による中綿30の保持力が軸筒10の案内リブ14による中綿30の保持力と中綿30に差し込まれたペン体20の中綿30との摺動抵抗との和よりも大きいので、図2に示すように、インキを使い切った中綿30は尾栓40に保持されたまま後退する。そして、尾栓40を軸筒10から取り外したときは、図3に示すように、中綿30は尾栓40に保持された状態で軸筒10から取り出すことができ、ピンセットのような治具を必要としない。また、中綿30は尾栓40とともに取り出せるので、中綿30に直接手が触れる可能性が少なく、手を汚すことがほとんどなくなる利点がある。
【0011】
【発明の効果】
以上説明したように、本発明は、インキを吸蔵した中綿が軸筒内に収容され、軸筒の先端開口に取り付けられたペン体の尾端部が中綿の先端部に差し込まれ、軸筒の尾端開口に尾栓が取り付けられた筆記具において、中綿の先端部を軸筒内面の案内リブで保持するとともに、中綿の尾端部が尾栓で保持し、尾栓の中綿保持力を、軸筒の案内リブの中綿保持力および中綿とペン体の接触抵抗の和よりも大きくするので、ユーザーが中綿を交換する際に、ピンセットのような治具を必要とせず、また、手が汚れることが少ない筆記具とすることができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a writing implement having a batting containing ink stored in a barrel.
[0002]
[Prior art]
The writing implement in which the batting filled with ink in the barrel is housed in the barrel, the tail end of the pen body attached to the tip opening of the synthetic resin barrel is inserted into the tip of the batting, The ink absorbed by the batting is supplied to the pen body and used for writing. A tail plug made of synthetic resin is attached to the tail end opening of the barrel.
[0003]
By the way, recently, there is a great need to reduce waste from the viewpoint of environmental protection and resource conservation.For this reason, even in the batting-type writing implement, when the batting ink is used up, the batting is not disposable, but the batting is used. In many cases, they replaced them with new ones and used writing tools for a long time while using parts such as barrels as they were.
[0004]
[Problems to be solved by the invention]
When the user replaces with a new batting, it is necessary to take out the batting that has used up the ink from the barrel, but since the rear end of the pen body is inserted into the batting, use a jig such as tweezers to fill the batting. Must be pulled out of the barrel. In addition, at this time, the hand may directly touch the batting, and there is a disadvantage that the hand becomes dirty.
[0005]
Therefore, an object of the present invention is to provide a writing instrument that does not require a jig such as tweezers when a user replaces a batting, and that is less likely to stain his hands.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the present invention provides a method in which a batting filled with ink is housed in a barrel, and a tail end of a pen body attached to a tip opening of the barrel is inserted into a leading end of the batting. In a writing instrument with a tail plug attached to the opening at the tail end of the cylinder, the tip of the batting is held by the guide ribs on the inner surface of the barrel, and the tail end of the batting is held by the tail plug to increase the holding power of the tail plug. And the sum of the batting holding force of the guide ribs of the barrel and the contact resistance between the batting and the pen body.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. In FIG. 1, a tip of a shaft cylinder 10 formed of a synthetic resin is a tapered portion 11, and a cylindrical pen body holding portion 15 is formed in a center hole of the tapered portion 11. Note that the tapered portion 11 may be used as a front end of another component. A plurality of guide ribs 14 are formed at the tip of the inner surface of the barrel 10, and an inner screw 12 is formed at the tail end of the inner surface.
[0008]
A plurality of batting retaining ribs 45 are formed on the inner peripheral surface of the tail plug 40, and an outer screw 41 is formed on the outer peripheral surface, and the inner screw 12 of the barrel 10 and the outer screw 41 of the tail plug 40 are screwed. The tail plug 40 is attached to the tail end opening of the barrel 10 by the combination. The batting 30 is made of rods formed by gathering crumpled ultrafine fibers, and absorbs water-based ink. The front and rear of the batting 30 are held by the guide rib 14 of the barrel 10 and the batting holding rib 45 of the tail plug 40 and housed in the barrel 10. The pen body 20 is a rod-shaped body made of a synthetic resin having open cells, and is held by the pen body holding unit 15. The tail end of the pen body 20 is inserted into the batting 30. Therefore, the water-based ink absorbed in the batting 30 is supplied to the pen body 20 and used for writing. When not in use, the cap 50 is fitted to the barrel 10 to prevent ink from evaporating from the pen body 20.
[0009]
Here, the tip of the batting 30 is held to such an extent that the batting 30 is lightly contacted with the guide rib 14, and the holding force of the batting 30 by the batting holding rib 45 of the tail plug 40 is determined by the guiding rib 14 of the shaft cylinder 10. It is much larger than the sum of the holding force and the sliding resistance of the pen body 20 inserted into the batting 30 against the batting 30. That is, the batting 30 is strongly held by the tail plug 40.
[0010]
When the user uses up the ink of the batting 30 and replaces it with a new batting 30, the user removes the tail plug 40 from the barrel 10 by rotating the tail plug 40 counterclockwise. Since it is larger than the sum of the holding force of the batting 30 by the guide ribs 14 of the cylinder 10 and the sliding resistance of the batting 30 inserted into the batting 30, as shown in FIG. 30 retreats while being held by the tail plug 40. Then, when the tail plug 40 is removed from the barrel 10, as shown in FIG. 3, the batting 30 can be taken out from the barrel 10 while being held by the tail plug 40, and a jig such as tweezers is used. do not need. In addition, since the batting 30 can be taken out together with the tail plug 40, there is little possibility that the batting 30 is directly touched by the hand, and there is an advantage that the hands are hardly stained.
[0011]
【The invention's effect】
As described above, according to the present invention, the batting containing the ink is housed in the barrel, the tail end of the pen body attached to the tip opening of the barrel is inserted into the tip of the batting, In a writing instrument with a tail plug attached to the tail end opening, the tip of the batting is held by the guide ribs on the inner surface of the barrel, and the tail end of the batting is held by the tail plug. It is larger than the sum of the batting retention force and the contact resistance between the batting and the pen body of the guide ribs of the cylinder, so the user does not need a jig such as tweezers when replacing the batting, and the hands become dirty. Less writing implement.
