JPH1120377A - Refill lead case - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a refill lead case wherein problems concerning portability and saving resources are solved. SOLUTION: A refill lead case is composed of a container principal body of which one end is open, a parting member 3 having a base part 4 having the same shape as a sectional inner surface shape of the container principal body and a partition part 5, and a cap 2 stationaryly attached to the opening part of the container principal body. The base and/or the partition part of the parting member are closely fitted to the container principal body, and a plurality of lead storing chambers are formed. Since a refill lead of a different diameter and a different color can be stored in each chamber thereby, its portability is excellent, and the conventional container principal body 1 can be used as it is.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extra lead case in which different core diameters and different color cores can be stored separately, that is, a plurality of lead storage chambers are formed.

[0002]

2. Description of the Related Art In a conventional extra lead case, one kind of lead is stored in a container body.

[0003]

In recent years, in which the diversification of core diameters and colors has become more demanding, consumers have come to demand, for example, a 0.5 mm diameter mechanical pencil and a 0.5 mm diameter mechanical pencil.
We have several types of mechanical pencils with different core diameters, such as 7mm mechanical pencils. Therefore,
It is necessary to own a plurality of types of refills corresponding to the mechanical pencils owned, which is not preferable from the viewpoint of portability and resource saving. Such necessity of preparing a plurality of kinds of refills is, for example, commonly referred to as a composite writing instrument or a multi-core writing instrument in which a plurality of color cores and core diameters can be used in one mechanical pencil. This is more noticeable in writing instruments (pencils) that are used.
In addition, although it is not impossible to store cores having different core diameters and colors in one case, in this case,
It is difficult to determine the diameter of the core, thereby causing an erroneous use, or there is a problem that the surface of the color core becomes dirty due to contact with a different color core.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a container body in which different core diameters and different color cores can be separately stored, that is, a plurality of core storage chambers are formed. Provided is a refill lead case that solves the problem of portability and resource saving, comprising: a partition having a container main body having an open end, a base portion having the same shape as a cross-sectional inner surface shape of the container main body, and a partition wall portion. And a cap fixed to the opening of the container main body.
Alternatively, the gist of the present invention is a spare lead case in which a partition part is closely fitted to the container body and a plurality of lead storage chambers are formed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The refill core container of the present invention includes a container body, a cap, and a partition member. FIGS. 1 to 3 show a first embodiment, in which a container body 1 comprises:
It has an opening at one end and is made of synthetic resin or the like.
The cap 2 is fixed to an opening of the container body 1.
It is formed of a synthetic resin or the like. The partition member 3 includes a base portion 4 and a partition wall portion 5 having the same shape as the cross-sectional inner surface shape of the container main body 1 (shown as a rectangle in the figure), and is formed of synthetic resin or the like. In this example, the partition member 3
A hollow rectangular partition 5 is connected to a rectangular base 4, and the partition 3 is tightly fitted to the container main body 1 to be integrated with the container main body 1.
Thus, the core storage chamber 6 and the hollow rectangular shape of the partition wall 5 form the core storage chamber 6, and a total of three core storage chambers 6 are formed.
The close fitting of the partition part 3 to the container main body 1 was performed by a portion where the narrow outer surface of the hollow rectangle of the partition wall part 5 and the inner surface of the container main body 1 were in parallel contact as shown in FIG.

FIG. 4 shows another example of the container main body of the present invention. In this embodiment, the close fitting of the partition portion 3 to the container main body 1 is tapered on the inner surface of the container main body 1 in the longitudinal direction. A portion 1a is formed, and is formed by the inner peripheral surface of the inner end portion of the tapered portion and the outer peripheral surface of the base portion of the partition portion.

FIG. 5 shows another example of the partition member of the present invention. The difference from the examples of FIGS. 1 to 3 lies in the shape of the partition wall portion 5 connected to the base portion 4. That is, in this example, a pair of thin rectangular plates is provided as the partition wall 5. Therefore, in this example, three core storage chambers are formed by the inner surface of the container body and the partition wall 5.
In this example, the close fitting of the partition part 3 to the container body is
It is more preferable to form the base portion 4.

FIG. 6 shows still another example of the partition member of the present invention. The difference from FIG. 5 is that a thin and elongated rectangular thin plate member serving as a partition wall portion 5 is formed. This is the point where the thin plate member is located at a substantially middle portion of the base portion 4. Therefore, in this example, two core storage chambers are formed by the inner surface of the container body and the partition wall 5.

FIG. 7 shows still another example of the partition member of the present invention. The difference from FIG.
The point is that the base part 4 is circular and the partition part 5 is radial. Therefore, in this example, four core storage chambers are formed by the inner surface of the container body and the partition wall 5.
Note that, in the case of this example, the cross-sectional inner surface shape of the container body is a circular shape like the shape of the base portion 4.

FIG. 8 shows still another example of the partition member of the present invention. The difference from FIG.
The base part 4 is formed in a rhombus shape, and the partition part 5 of the partition member 3 is formed.
Is a cross-shaped cross section.

As described above, in the present invention, various shapes can be adopted as the cross-sectional inner surface shape of the container main body and the cross-sectional shape of the partition member as long as they are the same shape. Various shapes can be adopted according to the number of chambers. When three or more lead storage chambers are formed, one lead storage chamber may store a writing tool lead other than a mechanical pencil, such as a ballpoint pen refill. Furthermore,
In the above example, the close fitting of the partition to the container body was performed by the container body and the partition of the partition member, or was performed by the container body and the base of the partition member. The part may be closely fitted to the inner surface of the container body at the same time.

[0012]

According to the present invention, there is provided a container body having one end opened, a partition member having a base portion and a partition wall having the same shape as the cross-sectional inner surface of the container body, and fixed to the opening portion of the container body. And a plurality of core storage chambers formed by closely fitting the base and / or the partition wall of the partition member to the container body, and thus having different core diameters and colors for each chamber. It is excellent in portability, can use the conventional container body as it is, and can store multiple kinds of cores only by changing the partition member, which is superior to the viewpoint of resource saving. It is an extra lead case.
