JP 2009-286018 A Japanese Patent Application Laid-Open No. 2008-247452 JP 2010-120684 A

The cylindrical storage container shown in Patent Document 3 is provided with a refill holding portion on the cap, so that the refill can be held without moving in the container in the stored state, and is stored in the container body when the cap is removed. The refill to be drawn is pulled out at the same time. For this reason, if the cap is pulled out with the cap tilted, the refill may be caught by contact with the opening of the container because it is long. In particular, the refill using a metal ink container that is not flexible. May cause problems such as bending or breaking and ink leakage. In particular, in the case of the embodiment shown in FIG. 3 (a form in which the chip is held by the cap), a large load is applied to the connection portion between the chip and the ink storage cylinder. This is particularly noticeable.
In addition, since the refill in the storage state is not connected to the container when the cap is opened, the cylindrical storage container cannot be used as a simple writing instrument, and is discarded after the refill is used (when the writing instrument body is stored). .

  The present invention solves the above-mentioned problems in the refill storage body using the conventional cap-type cylindrical storage container, and can stably hold the container main body without moving the refill in the container storage state even when the cap is opened. Provided is a writing instrument refill container that can be used as a simple writing tool and can be easily extracted without applying a load to a chip or an ink container when removing a cap or taking out a refill.

The present invention is a refill container comprising a container body having an opening at one end and a closing part at the other end, and a cap for sealing the opening of the container body, and storing a writing instrument refill inside. The writing instrument refill has a tip connected to the tip of the ink containing cylinder, and a writing instrument main body and a detachable joint member connected to the rear end of the ink containing cylinder, and the fitting member and the container main body are closed in the refill accommodated state. It is required that the tip end is housed in the container body in a protruding state and the tip end is covered with a cap.
Furthermore, it is a requirement that the container body is provided with a convex portion on the inner wall of the container for restricting the radial movement of the writing instrument refill.
Further, the joint member is colored in the ink color in the ink containing cylinder, one end of the joint member is fitted to the ink containing cylinder, and the other end is detachably fitted to the closing portion of the container body. It is necessary to be done.
Further, it is required that the cap is provided with an elastic inner plug that covers the tip end in the refill storage state, and that the cap can be fitted to the rear end of the container body.
In the present invention, “upper” indicates the direction of the opening of the container body, and “lower” indicates the bottom (closed portion) side of the container body.

  According to the present invention, the refill in the stored state can be stably held without moving even when the cap is opened, so that the container body can be used as a simple writing instrument having a gripping exterior. Further, when the cap is removed, the refill and the pen tip connection portion are not bent by contacting with the opening of the container main body, so that the refill can be easily pulled out without applying a load to the pen tip or the ink container. It becomes a writing instrument refill container.

It is a longitudinal cross-sectional view which shows one Example of the refill storage body of this invention. It is a longitudinal cross-sectional view which shows the cap removal state (rear insertion state) of the writing instrument refill storage body of FIG. It is a longitudinal cross-sectional view which shows the other Example of the refill storage body of this invention.

  The writing instrument refill storage body of the present invention is a case with a lid for storing a writing instrument refill in which a tip is connected to the tip of an ink storage cylinder containing ink and a writing tool body and a detachable joint member are connected to the rear end. At the time of storage, the joint member is joined to the closing portion of the container body.

  The writing instrument refill has a pen tip member (chip) such as a marking pen tip or a ballpoint pen tip attached to the tip of an ink containing cylinder containing ink as a writing tip, and a joint that is detachable from the writing tool body at the rear end. It is a refill-type ink container that can be exchanged for a writing instrument body such as a marking pen or a ballpoint pen, but a mechanical pencil unit can also be applied.

As the ink containing cylinder containing the ink, for example, a molded body (single layer or multilayer molded body) made of a thermoplastic resin such as polyethylene, polypropylene, polyethylene terephthalate, nylon, or a metal processed body such as a stainless steel pipe is used. It is done. In particular, when a transparent, colored transparent, or translucent resin molded body is used as the ink container, the ink color and the remaining amount of ink can be confirmed from the outside. Moreover, a joint member can also be integrated by shape | molding and processing in the shape where the rear end side of a cylinder becomes a joint member.
In addition to directly connecting the chip to the ink storage cylinder, the ink storage cylinder and the chip are connected via a connecting member. In particular, when a chip is connected to an ink containing cylinder made of a metal processed body or a colored opaque resin molded body via a connecting member, the connecting member is formed of a resin having transparency, so that the inside of the refill can be formed via the connecting member. The presence or absence of ink can be confirmed.

As the ballpoint pen tip, a tip formed by holding a ball in a ball holding portion in which the vicinity of the tip of a metal pipe is pressed and deformed inward from the outer surface, or a metal material is formed by cutting using a drill or the like. A chip formed by holding a ball in a ball holding part, a chip provided with a resin ball receiving seat inside a metal or plastic chip, or a ball held by the chip is biased forward by a spring body. Can be applied.
Further, the ball having an outer diameter of 0.15 to 2.0 mm, preferably about 0.28 to 1.2 mm, such as cemented carbide, stainless steel, ruby, ceramic, resin, or rubber can be applied.

  Further, as the marking pen tip, a porous member having a continuous ventilation hole selected from a range of generally 30 to 70% of a conventional general porosity, such as a resin processed body of a fiber, a fusion processed body of a heat-meltable fiber, and a felt body. Is used for practical purposes by processing one end into a shape corresponding to the purpose such as a bullet shape, a rectangular shape, a chisel shape, or the like.

  When applying the marking pen tip, an ink occlusion body consisting of a fiber bundling body is built in the ink containing cylinder, the tip is connected directly or via a relay member, or the pen tip is pressed between the ink and the tip. It is preferable to interpose a valve body that is opened by the above and a comb groove-shaped ink flow rate adjusting member.

The joint member is a portion that is joined (joined) inside the writing instrument body when the refill is accommodated in the writing instrument body, and is configured in a shape suitable for the corresponding writing instrument, such as a protrusion, a hole, or a recess. Although the joint member can be formed integrally with the ink storage cylinder, it is preferably connected to the rear side of the ink storage cylinder as a separate member from the viewpoints of formability and assemblability. The connection strength needs to be stronger than the connection to the writing instrument body.
Further, the joint member can also function as a color display portion by coloring the ink color in the ink containing cylinder (in the color-changing ink, any hue before and after the color change). This is useful because the user can visually select a desired refill when using a dye-based ink or an opaque ink container.

As the ink contained in the ink container, water-based gel ink having shear thinning, low-viscosity water-based ink, low-viscosity oil-based ink, high-viscosity oil-based ink, emulsion ink, etc. Ink can be applied.
As the colorant applied to the ink, any of general-purpose dyes, pigments, metallic glossy pigments, fluorescent pigments, titanium oxide, thermochromic materials, photochromic materials, and the like can be used.

  Further, if necessary, an ink follower made of a high-viscosity fluid that moves forward as the ink is consumed can be closely disposed at the rear end of the ink contained in the ink storage cylinder. Further, a solid follower can be used in combination with a high viscosity fluid.

The container body for storing the refill has an opening at one end (upper side), and a bottom surface (a hole having a size that prevents the refill from falling or closing) so as to form a refill storage portion therein, and the joint member is joined. (Closed part) is provided at the other end (downward) and is formed from metal, wood, resin, etc., but resin is suitable because it is highly moldable and inexpensive. . In addition, any shape may be used as the outer circumferential or inner radial cross-sectional shape, but the inner (refill storage portion) is preferably the same shape as the cross section of the ink storage cylinder of the refill, more preferably It is formed in a circle. As a result, the internal empty space in the housed state becomes constant and becomes easy to hold.
In the case of a resin molded product, the container may be either transparent or opaque, but is preferably formed of a transparent material so that the writing instrument refill can be visually recognized from the outside.
Further, the container main body may be constituted by a single member, or may be constituted by using a holder or a tail plug-shaped part. In this case, since it becomes possible to make a container main body into a complicated shape, the effect by fine dimension prescription | regulations, such as cap fitting, a connection of a coupling member, and also refill clamping, becomes easy to be acquired.

In particular, it is preferable that the closing part connects a tail plug formed as a separate body to the cylinder. By using a separate tail plug, the position and shape (size) of the portion (holding portion) to which the refill joint member is joined can be adjusted in a complicated and fine manner.
The holding portion is formed so as to be detachable in accordance with the shape of the refill joint member, and is formed in the same or similar shape as the joint member connecting portion of the writing instrument body. Therefore, even if the opening side is faced down with the cap removed, writing can be performed without dropping the refill, and when the chip side is gripped and the refill is taken out, it can be easily taken out.
Moreover, the fitting part which can insert a cap back can also be formed in the lower part of a tail plug, and when using it as a simple writing instrument, it can suppress that a cap loses.

  Furthermore, it is also possible to form an engaging part for holding the writing instrument refill (that is, holding at two or more opposite locations) integrally or separately on the inner wall part of the container body. Since the refill in the stored state is held at a fixed position by the locking portion without shaking in the radial direction, rattling when used as a simple writing instrument can be suppressed, and writing performance is improved.

The cap is a substantially cylindrical member having a shape capable of sealing the container opening in a state where a part of the protruding chip or the ink storage cylinder is covered, and protects the tip of the refill to be stored. One end (lower end) of the cap is open, and the opening has a structure that fits in the vicinity of the container body opening. The cap can hold a chip or a refill. In this case, the refill joined to the joint member in the container is held with a holding force that does not come out when the cap is removed.
Inside the cap, an inner plug (particularly formed of an elastic material) for protecting the tip end of the refill chip in the housed state can be provided. Accordingly, inadvertent ink leakage from the pen tip can be suppressed without using a hot melt protective film, and the taken-out refill can be used immediately without having to remove the protective film.
In addition, when a structure in which the cap can be fitted to the rear end of the container body is applied, it is possible to write with the writing instrument refill container alone with the cap in the back, and when the short refill is stored. Even if it exists, the total length at the time of writing can be lengthened.

  On the outer surface of the writing instrument refill container having the above-described structure, it is possible to display information related to the refill to be stored.In addition to the name and part number of the writing tool main body that can be stored, for example, the ink color to be built in, the type of nib, By displaying the thickness, ball diameter, etc., the refill information in the storage state can be disclosed to the user.

Embodiments of the present invention will be described with reference to the following drawings.
FIG. 1 is a view showing a writing instrument refill housing 1 according to the first embodiment of the present invention, and FIG. 2 is a view showing a cap rearward state of FIG. Moreover, FIG. 3 is a figure showing the writing instrument refill storage body of a 2nd form.

Example 1 (see FIGS. 1 and 2)
The writing instrument refill container 1 shown in FIG. 1 is in a state in which the writing instrument refill 4 including the ink containing cylinder 6 and the chip 5 protrudes from the opening 21 in the container body 2 that opens and closes the opening 21 with the cap 3. It is something to be stored.

The writing instrument refill 4 includes a ball-point pen tip 5 in which a ball is rotatably held at a front end, and a resin pipe (specifically, a polypropylene having transparency) provided with the ball-point pen tip 5 at the front end and having an open rear end. The chip 5 and the ink storage cylinder 6 are connected by a resin connection member 51. Further, a resin joint member 7 having a rod-like portion for joining to the inside of the writing instrument main body is press-fitted to the rear end of the ink containing cylinder 6 to form a refill exterior. In particular, the rod-shaped portion of the joint member 7 is formed in a shape and a size corresponding to a portion to be joined inside the writing instrument body when the refill 4 is accommodated in the writing instrument body (in this embodiment, a cylindrical member). The entire joint member functions as a color display portion by coloring the same hue as the ink stored in the ink storage cylinder 6.
The ballpoint pen tip in the drawing has a structure in which a ball is held by a ball holding portion formed by cutting a metal material with a drill or the like. A structure in which the ball is in close contact with the inner surface of the edge portion can also be applied. The ball-point pen tip can also be directly attached and fixed to the front end opening of the ink containing cylinder 6 by press fitting or the like.

  In addition, an ink 61 selected from a water-based gel ink having shear thinning viscosity, a low-viscosity water-based ink, a low-viscosity oil-based ink, a high-viscosity oil-based ink, or the like is incorporated in the ink containing cylinder 6. An ink follower 62 made of a high-viscosity fluid that advances as the ink is consumed is filled at the rear end of the ink 61.

  In this embodiment, a ballpoint pen refill is used as the writing instrument refill 4, but a refill in the form of a marking pen using a marking pen tip made of fiber or resin at the pen tip, or a refill in the form of a mechanical pencil (mechanical pencil unit) It is also possible to apply. Further, the fiber converging body and the comb-like ink flow rate adjusting member can be accommodated in the ink accommodating cylinder 6.

  The container body 2 for storing the writing instrument refill 4 has an opening 21 for inserting (accommodating) and taking out the refill 4 at the upper end, and by joining the lower end (the closed portion serving as the bottom surface) to the joint member 7. This is a container that is closed so that the refill 4 can be held, and in this embodiment, a concave portion (holding portion 23) that engages the joint member 7 is integrally formed upward at the lower end of a transparent polycarbonate molded cylinder. The container body 2 is formed by press-fitting 22. In addition, a film or a seal on which the information about the ball diameter, ink color, product number, price, and applicable writing instrument body of the refill 4 to be stored can be transferred and pasted on the outer surface of the polycarbonate molding cylinder. This is a place where various information can be provided to the user.

  The holding portion 23 formed in the tail plug 22 is formed of a circular concave hole that fits with the joint member 7 and has a shape that can hold the refill 4 by forming an annular rib on the inner surface of the hole portion. . The holding force (fitting force) between the joint member 7 and the holding portion 23 is set so as to be smaller than the fitting force between the joint member 7 and the ink containing cylinder 6. ) Is easy to perform.

When the writing instrument refill 4 is stored in the container main body 2 from the rear end (that is, the joint member 7 side), the joint member 7 is connected to the holding portion 23 of the tail plug 22, and the upper side of the tip 5 and the connection member 51. A part of is projected outward (upward) from the container body opening 21. Therefore, when pulling out the writing instrument refill 4 from the container body 2, these protruding portions can be directly held, and the refill 4 can be reliably pulled out using both hands while holding the outer surface of the container body 2 with one hand. Become.
In addition, as a protrusion part, it accommodates in the state which can hold | grip a part of refill 4 only to a chip | tip upper part, etc. to the ink accommodating cylinder 6 upper part.

The cap 3 covers the refill 4 housed in the container body 2 in a protruding state of the chip 3 from the chip 5 side and seals the opening 21, so that the internal refill 4 (chip 3) together with the container body 2 is sealed. ).
The cap 3 of the present embodiment is formed such that a cylindrical molded member made of polypropylene resin seals one end, and is fitted on the outer peripheral surface on the opening end side with the fitting portion (the inner surface of the opening portion 21). An annular rib to be a part) is integrally formed. Further, the inner peripheral surface on the opening end side of the cap 3 is not fitted to the outer surface of the writing instrument refill 4 (chip 5 and connecting member 51). Note that the cap 3 having the above-described shape has a shape that fits into a recessed portion at the rear end of the container body 2 (behind the tail plug 22), so that the cap 3 can be inserted backward. For this reason, since writing in the cap rearward state is possible, it is possible to lengthen the entire length of the writing instrument refill container 1 during writing even when a short refill is stored (FIG. 2).

By the said structure, the writing instrument refill storage body 1 at the time of storage of the refill 4 can protect a refill reliably from dropping, the impact at the time of transportation, etc. Further, when the refill is used, when the writing instrument refill 4 is taken out from the container body 2 after the cap 3 is removed, the protruding tip side can be directly held and pulled out, so that contact between the opening 21 and the refill 4 can be achieved. It becomes easy to pull out vertically without applying a load due to an angle. Therefore, it is possible to reliably suppress the ink containing cylinder 6 and the tip 5 from being bent or detached when the refill is taken out.
Furthermore, since the refill 4 in the stored state can be stably held without moving even when the cap 3 is opened, it can be used as a simple writing instrument having the container body 2 as an exterior for gripping. Since loss can be prevented, it is excellent in applicability and convenience.

Example 2 (see FIG. 3)
The writing instrument refill housing 1 shown in FIG. 3 of the present embodiment has the same configuration as that of the first embodiment except for the inner wall surface shape of the container body 2 and the internal structure of the cap 3.

In the container body 2 of the present embodiment, a holding convex portion 24 made of an annular rib is integrally formed on the inner surface of one end (opening end side) of a polypropylene cylindrical body.
The height of the convex portion 24 from the inner wall surface is set to a dimension that allows the convex portion 24 to be clamped at opposite locations in accordance with the outer diameter of the ink storage cylinder 6 to be stored. In the present embodiment, the ribs are formed in a ring shape on the opening 22 side. However, the present invention is not limited to this, and a plurality of ribs may be formed in the axial direction or a wide ring shape. It can also be formed by a plurality of protrusions.

  The cap 3 has a chip protection member (inner plug 31) made of a rubber elastic part in the shape of a cup locked inside a cylindrical molded member made of polypropylene resin that seals one end. Therefore, it has a more airtight structure, and even a refill containing ink that is easy to dry up can be stored and held for a long time without the need to apply a protective film (seal peel).
