Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging display writing instrument. More specifically, the present invention relates to a hanging display writing instrument that is displayed and sold in a suspended state in a supermarket, a convenience store, or the like.

[0002]

2. Description of the Related Art Conventionally, writing instruments such as felt-tip pens, ball-point pens, and marking pens have been sold in a state of being suspended in a package at stores such as supermarkets and convenience stores.

In the case of the above display mode, if the display is hung with the pen point facing upward, handwriting blur at the time of initial writing tends to occur due to the ink dropback phenomenon.
On the other hand, if the pen tip is hung downward and displayed, the ink may leak from the pen tip due to excessive supply of ink to the pen tip.

In particular, a writing instrument containing a pigment-dispersed ink (eg, a writing instrument for a writing board containing a pigment-dispersed writing board ink (so-called whiteboard ink) that can be wiped off with a dry cloth) When the pigment is severely settled and the pen tip is displayed in an upward state for a long period of time, the dispersed state of the pigment tends to be unevenly distributed downward, resulting in a decrease in color tone. Conversely, if the pen tip is left down, the dense pigment is unevenly distributed at the tip of the pen tip, which tends to cause clogging of the pen tip and poor ink output. In the writing instrument for a writing board, if the ink outflow performance is not properly maintained as described above, not only a handwriting having a normal density cannot be formed, but also the erasability of the handwriting will be affected. It had been.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is intended to avoid the danger of handwriting blur and ink leakage at the time of initial writing, and to suspend the original initial writing performance. It is intended to provide display writing instruments. In particular, it is an object of the present invention to provide a writing instrument for a writing board containing a pigment-dispersed ink for a writing board, and to provide a hanging display writing instrument capable of maintaining a handwriting of a constant density without causing ink ejection defects.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a hanging display writing instrument 1 which is displayed and sold in a suspended state, and comprises a first ink absorbing member 6 impregnated with ink (particularly, pigment ink).
And a shaft cylinder 3 having a pen tip 5 connected to the first ink storage body 6 and protruding to the outside, and comes into contact with the pen tip 5 when mounted on the shaft cylinder 3. A cap 4 having a second ink storage 7 disposed therein;
It is required to be provided with a locking portion 8 provided on the top side of the cap 4 or the bottom side of the barrel 3 and lockable to the display hook 10.

[0007] According to the above configuration (claim 1), the pen tip 5 does not constitute the end (lower end) of the ink holding, so that the influence of the sedimentation of the pigment is reduced. That is, even if the hanging display writing instrument 1 having the above-described configuration is hung and displayed in the upward state of the pen tip 5, the ink in the pen tip 5 does not drop back due to the capillary force of the second ink storage body 7,
It is possible to avoid a drop in handwriting density due to the ink dropback phenomenon, and furthermore, even if the pen tip 5 is hung downward and displayed, ink (especially a pigment component) tends to be excessively unevenly distributed at the end position ( (The lower end position) is present in the second ink occluding body 7 housed and arranged in the cap 4, so that the surplus ink of the pen tip 5 is absorbed by the second ink occluding body 7, and the pen tip 5 is clogged. And the ink leakage from the pen tip 5 can be prevented. Therefore, during initial writing, there is no risk of handwriting blur and ink leakage, normal initial writing performance can be maintained, and the user can use the printer with peace of mind.

In the hanging display writing implement 1 (Claim 1), the writing implement main body 2 composed of the cap 4 and the shaft cylinder 3 is housed inside a package 9 having the locking portion 8. (Claim 2) is preferred. The package 9 protects the writing instrument main body 2 of the product from dirt and damage, and allows the display of the product name, precautionary statement, price, bar code, and the like to be freely printed on its surface. In addition, by using the package 9 integrally provided with the locking portion 8,
There is no need to provide the locking portion 8 in the writing instrument body 2 in advance.

In the hanging display writing instrument 1 (Claim 1), the locking portion 8 is integrally provided on the top (top) side of the cap 4 or on the bottom (tail) side of the barrel 3. (Claim 3) is preferred. Thereby, the package 9
Is unnecessary, so that materials can be saved and garbage can be reduced.

(Ink Occlusion Body) The first ink occluding body 6 and the second ink occluding body 7 are preferably porous bodies having capillary gaps for absorbing and storing ink therein. , A fiber processed body (for example, a fiber convergence body,
Heat-fused fibers, resin-processed fibers, etc.), felt, plastic porous bodies (sponge) having continuous pores, etc. can be exemplified.

The capillary force of the first ink occluding member 6 and the second ink occluding member 7 is set to be smaller than the capillary force of the pen tip 5. Thereby, the pen tip 5 can always be in a state of being impregnated with an appropriate amount of ink.

Further, a second housing accommodated in the cap 4 is provided.
Is fixed to the inner surface of the cap 4 by means such as press fitting. The front end of the pen tip 5 is configured to be able to freely contact and separate from the second ink storage 7 as the cap 4 is attached and detached.

(Pen Tip) The pen tip 5 includes a fiber converging body, a plastic porous body, a writing brush, a plastic extruded body (having an ink outlet in the inside or outside in the axial direction),
Ballpoint pen tips (having an ink guide core inside) and the like.

(Locking Portion) The locking portion 8 only needs to be lockable to the display hook 10 provided at the storefront, and may have, for example, a hole shape having a cutout portion, a cutout portion, or the like. A key shape or the like without a notch can be given.

(Packaging Body) The packaging body 9 is formed, for example, by stacking two transparent thermoplastic resin films and sealing the periphery thereof by heat welding, the base plate 91 and the transparent packaging sheet 9.
2, a so-called blister package 9 or an opaque aluminum bag.
