Description

  The present invention relates to a writing instrument refill container. Furthermore, the present invention relates to a writing instrument refill storage body in which a writing instrument refill is stored in a container body with a cap.

Conventionally, in writing instruments such as ballpoint pens, refills equipped with a pen tip and an ink storage cylinder are accommodated in a shaft cylinder having a replaceable structure so that they can be reused by replacing them with new refills after ink consumption. Are widely sold. In addition, writing instruments that users can select and purchase as their favorite refills and separate writing instrument main bodies (shaft cylinders) can be used as original writing instruments.
The refill applied to each writing instrument is generally displayed and sold at a store in a state of being housed and packaged in a film (see, for example, Patent Document 1). On the other hand, what was accommodated in the cylindrical container with a cap is disclosed for the purpose of attaining space saving at the time of a refill display or transportation (for example, refer patent document 2).

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

The cylindrical storage container disclosed in Patent Document 2 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 ink leakage.
Further, when the pen tip as shown in FIG. 3 of Patent Document 2 is held, a large load is applied to the connection portion between the pen tip and the ink storage cylinder, and thus the above-mentioned problem when the cap is pulled out obliquely is caused. This is particularly noticeable.

  The present invention solves the above problems, and even in a cap-type refill container using a cylindrical container, a load is applied to the pen tip and the ink container when removing the cap or taking out the refill. It is possible to provide a writing instrument refill storage body that can be easily pulled out and can be stably held without moving the refill in the storage state.

The present invention is a refill storage body in which a writing instrument refill consisting of at least an ink storage cylinder and a chip is stored in a container body whose opening is opened and closed with a cap, wherein the ink storage cylinder protrudes from the opening of the container body And a writing instrument refill container characterized in that it is held by the inner wall of the container body.
Further, the writing instrument refill is required to be stored in the container body with the tip side protruding, and the container body is provided with a holder member having a through hole in the opening, and the holder member contains ink inside the through hole. It is necessary to hold the tube and fit with the cap.
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, even if it is a cap-type refill container using a cylindrical storage container, the refill is not bent by contact with the opening of the container body when the cap is removed, and the pen tip or the ink storage cylinder Thus, the refill can be easily pulled out without applying a load to the writing instrument, and in the stored state, the refill can be stably held without moving the refill.

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

  The writing instrument refill container of the present invention is a container in which a writing instrument refill comprising at least an ink containing cylinder and a chip containing ink is accommodated in a container body in a state in which a part of the ink containing cylinder projects. The cap is sealed so as to cover a part of the protruding ink storage cylinder with a cap that is detachable.

The container main body has one end (upper) and a cylinder having a bottom surface (a portion having a hole that is large enough not to be closed or refilled) at the other end (lower) so as to form a refill storage portion inside. Although it is formed from a metal, wood, resin or the like, a resin is preferable because it has high moldability and can be obtained at low cost. 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 prescriptions, such as cap fitting and refill clamping, will become easy to be acquired.

On the inner wall of the container body, a holding part for holding the writing instrument refill (that is, holding at two or more opposite locations) is formed as an integral or separate member, and the refill in the stored state is at a fixed position. Is retained. Therefore, the refill does not move in the container in the storage state, and the storage state can be maintained without dropping the refill even when the container opening portion is directed downward with the cap removed.
The holding portion may be the entire wall surface, but it is preferable to partially provide ribs or protrusions. In addition, as said protrusion, it is preferable to arrange | position the plurality of the same shape at equal intervals in the circumference.
In particular, when a separate holder member (having a through hole) is fitted to the container opening, the inner wall of the through hole is used as a holding part according to the outer diameter of the refill, or the inner wall of the through hole is made of ribs, protrusions, It is preferable to form a part. In this case, since it becomes easy to form a holding | maintenance part separately, it can form with a more highly accurate dimension. In addition, the holder member can be formed with a fitting portion for fitting a cap, so that the cap can be fitted with higher airtightness.

In addition, when the tail plug is used as a separate body, a holding portion extending upward from the bottom surface can be formed, and a structure in which the refill is sandwiched between the inner walls of the container can be taken. In this case, a structure is preferable in which an upwardly extending portion of the tail plug is formed in an annular shape and a refill is inserted and held in the annular portion. The tail plug may be formed with an air hole penetrating the inside and outside of the container to secure an air flow path when the cap is attached / detached.
Furthermore, the fitting part which can insert a cap back can also be formed in the lower part of a tail plug, and it can suppress that a cap is lost when taking out a refill.

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 ink storage cylinder is covered, and protects 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 (above the holder if the holder member is provided).
When the refill protrudes from the pen tip side and is stored, it is preferable that an inner plug (particularly formed of an elastic material) for protecting the tip end of the stored refill tip is provided in the cap. 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 applying a structure in which the cap can be fitted to the rear end of the container body when the pen tip side of the refill is protruded and stored, writing with the writing instrument refill container alone with the cap placed backwards Is also possible. In this case, in order to suppress refill wobble at the time of writing, it is preferable to provide two or more holding portions of the container body in the axial direction.

  The writing instrument refill is a refill configuration in which a pen tip member such as a marking pen tip or a ballpoint pen tip is mounted as a writing tip on an ink containing cylinder containing ink, and is replaceable with a writing instrument body such as a marking pen or a ballpoint pen. However, it is also possible to apply a mechanical pencil unit.

As the ink containing cylinder containing the ink, for example, a molded body made of a thermoplastic resin such as polyethylene, polypropylene, polyethylene terephthalate, nylon, or a metal processed body such as a stainless pipe is used. 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.
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.

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.

  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.
