BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat refill housing case in which at least a part of both a front wall surface and a rear wall surface has transparency so that the inside can be seen through.

[0002]

2. Description of the Related Art Many cases for accommodating a replacement core, such as a core for a sharp pencil and a core for a red holder, have a flat shape. In addition, although the back wall side may be non-transparent, at least the front wall surface is made of a molded product such as a transparent synthetic resin, and there is a part such as a printed part that prevents internal see-through. However, it is general that at least a part of the film has transparency that allows internal transparency.

However, since the refill is a self-wearing body, the core powder inevitably adheres as dirt to the inside of the case due to the movement of the refill inside the case due to transportation or the like. Even in such a case, the presence of the extra lead can be confirmed by seeing through the inside, but it is not beautiful and the commercial value is reduced.

[0004] Although depending on the type of refill, there is also a problem in light resistance. For example, a normal fired black core is manufactured by impregnating an oil into a core, but if the core is exposed to light for a long period of time, the oil may deteriorate with time. In the case of a color core, discoloration becomes a problem.
The quality must be reduced during display at the store, and the user may purchase it, so such a situation must be suppressed as much as possible.

For this reason, a case in which the degree of transparency is kept low.
There are also That is, it is formed by mixing a small amount of a coloring material with a material, and the inside stain is not noticeable, and the light resistance is also improved. However, the internal transparency is inevitably reduced by the amount of the coloring, and if it is compromised, it becomes rather unfavorable as a whole.

[0006]

According to the present invention, the front wall surface is exclusively used as a light-facing surface in a storefront display or the like, but when the purchased user confirms the presence of a replacement core, the front wall surface is not necessarily used. It is made by paying attention to the flatness of the case shape and the existence of the wall surface difference between the front wall surface and the back wall surface, which does not mean that the inside is only seen through from the inside, and the back wall surface of the case has By making the transparency higher than the transparency of the front wall surface, the dirt inside is not conspicuous at least until it reaches the user's hand, the light resistance is sufficient and the deterioration in quality can be suppressed,
In addition, the case has good internal transparency.
That is, in the present invention, in the flat-shaped refill housing case, at least a part of both the front wall surface and the back wall surface has transparency that allows internal see-through, the back wall surface has The gist of the present invention resides in a case where the transparency is higher than the transparency of the front wall surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example will be described with reference to the accompanying drawings. FIG.
, The case body 1 is made of a polyester resin, an acrylic resin, a methacrylate resin, a vinyl chloride resin,
Vinyl acetate resin, polystyrene resin, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-
The base material is a transparent resin such as a styrene copolymer, which may be lightly colored or the like, but is molded as having sufficient transparency. The front wall surface 2 and the back wall surface 3 may be appropriately printed with a product name, a manufacturer, or the like.
(See FIG. 2). An appropriate number of extra cores 5 are accommodated in the case body 1 and a cap 6
Is provided. Here, the one shown in the figure has a flat rectangular parallelepiped shape, but if it is flat, for example, it may have a gentle roundness as a whole. The front wall surface 2 and the back wall surface 3 may be, for example, oval or the like. The cap 6 is attached to the case body 1.
On the other hand, it may be detachable, pivotally attached, or slidably attached. The opening and closing structure is also appropriate, and may be opened and closed by operating an operation unit provided on another surface.

The case body 1 shown in FIG.
The difference in transparency between the two surfaces is due to the printing surface 4 described above. The printing includes gravure transfer printing, metal deposition printing, hot stamp printing, offset printing, pad printing, silk printing, etc., and the transparency of the front wall surface 2 is suppressed as compared with the back wall surface 3 by appropriate printing. And That is, even if there is shading,
The colored layer is formed over at least the entire surface of the accommodating portion of the refill core 5 on the front wall surface, and at least a part of the colored layer has internal transparency. here,
As an example of a preferable printing, printing by metallization transfer printing in a half mirror tone is exemplified. For example, a gravure printing layer such as a soft hardness or a core diameter, a light color ink printing layer for adjusting the ground color, and a metal deposition of aluminum or the like for imparting a half mirror tone light reflectivity and light transmittance to a base film. layer,
A heat-transfer-printed product using a transfer film provided with a glue can be viewed through the inside depending on the viewing angle, and has a metallic luster.

As shown in FIG. 3, the case body 1 may be a combination of a front member 7 having the front wall surface 2 and a back member 8 having the rear wall surface 3. Front member 7,
The back member 8 may be made of any appropriate material as described above. In the case shown in FIG. 3, the printing surface 4 is formed on the front member 7. The difference in transparency due to the difference in material and the difference in coloring may be used as it is.

[0010]

The refill housing case of the present invention is a flat refill housing in which at least a part of both the front and back walls has transparency that allows internal see-through. In the case, since the transparency of the back wall surface is higher than the transparency of the front wall surface, dirt inside the case is inconspicuous when the product is displayed at a store, and light resistance is high. Is good and can suppress the quality deterioration of the refill,
The interior can be seen through the front wall side, but it is very easy to check the internal state by looking at it from the back wall side.
