Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for storing writing instruments such as colored pencils, crayons and pastel.

[0002]

2. Description of the Related Art Heretofore, a sleeve type outer box and a case for storing a color pencil or the like having an inner box which can be inserted into and removed from the sleeve type outer box as a storage portion have been known. This type of case is often used because it can be made of a thin paper material and is easy to assemble as compared with a so-called covered case.

However, the case is made of relatively thin paper,
When partitioning a large number of colored pencils one by one and arranging them in a line, a partition plate made of paper or plastic is attached to a part of the inner box for partitioning, but this partition plate attachment work is complicated. . Also, if only a part of the inner box is partitioned, if it becomes short due to the use of colored pencils, etc., it will fall out of the partition, and it will not be possible to store it in an aligned manner and it will fall apart. Further, when a large number of colored pencils and the like are stored side by side, it is difficult to take them out and the paper case is damaged.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention does not require the work of attaching a partition plate, and the writing instruments such as colored pencils can be stored in an aligned state without being disassembled and can be taken out. Is to provide a durable case that is easy to

[0005]

SUMMARY OF THE INVENTION The present invention is a case for a writing instrument which has a sleeve-type outer box, and an inner box which can be inserted into and removed from the sleeve-type outer box as a storage portion. A partition wall is provided along the entire length (longitudinal direction) of the writing utensils to store colored pencils, etc., so that it can be bent in the front and back directions at the part near one end of the inner box in the longitudinal direction of the stored items. It is a case in which the flaps that prevent the pencil lead from breaking at both ends in the direction are connected to prevent falling of stored items.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The case of the present invention will be described with reference to FIGS. In the following, the vertical direction, the horizontal direction, the head,
The expressions such as tail are used, but they are based on FIG. 1 is a plan view of the inner box as a whole, FIG. 2 is a plan view of an inner box of another embodiment, FIG. 3 is a vertical sectional view of the inner box at the position shown in FIG. 2, and FIG. It is a perspective view of the state where it was stored. The inner box of the case of the present invention is integrally made by vacuum forming plastic such as polypropylene. The outer circumference of the inner box 1 is surrounded by an outer frame 2, and the outer frame extending in the vertical direction (the inserting / removing direction of the inner box) has a dividing portion at a portion 4 near one end in the vertical direction.

In order to store the stored items in the inner box one by one, a partition wall 3 is provided on the bottom of the inner box along the longitudinal direction according to the number of stored items. Each of the partition walls is lower in height than the outer frame and is provided over the entire length in the vertical direction, but is divided at the same position as the dividing portion 4 of the outer frame extending in the vertical direction. The width is the same as the outer frame dividing part 4. Then, this portion 6 is composed of only the bottom plate having the divided width in the lateral direction, and the inner box can be bent in the front and back directions at this portion. When storing things such as colored pencils in each partitioned compartment, they are close to each other and difficult to take out,
As shown in FIG. 4, it is a characteristic of this case that it can be taken out very easily by bending it at the dividing part (inner box bending part) 6 to the back side. Since the partition wall 3 is provided over the entire length in the vertical direction, even if it is shortened by using colored pencils, etc., it always fits in a properly partitioned partition,
No rattling when stored.

The sleeve-type outer case 9 of the case of the present invention can be formed of plastic or cardboard, and it is aesthetically pleasing if it is colored or a picture or a letter indicating the contents is printed.

[0009]

Next, the present invention will be described with reference to examples. First Embodiment FIG. 1 shows a first embodiment of the present invention, which is a basic form of the present invention. As shown in the figure, the inner box 1 has an outer circumference surrounded by an outer frame 2,
The outer frame extending in the vertical direction (the insertion / removal direction of the inner box) has a dividing portion in the vicinity 4 of one end in the vertical direction (a portion about 1/4 of the entire length from the end). A partition wall 3 is provided at the bottom of the inner box along the longitudinal direction according to the number of stored items. Each of the partition walls has a height lower than that of the outer frame and is provided over the entire length in the vertical direction except that the partition wall is divided at the same position as the dividing portion 4 of the outer frame. The dividing portion 6 has the same width as the outer frame and the partition wall,
Therefore, this part consists of only the bottom plate of the divided width in the lateral direction, and the inner box can be bent to the back side at this part (inner box bending part), as shown in FIG. It can be taken out very easily. The inner box is fitted into the outer box 9. Since it is surrounded by the outer frame 2, the shape of the inner box is maintained and it is easy to put in and take out.

Example 2 Basically the same as Example 1, except that flaps 8 projecting from the bottom are continuously provided at both longitudinal ends of the inner box 1, and the flaps 8 are folded back to the front side so that the head and the tail respectively. It is designed to cover a part of. On the surface of the head flap, the color name of the stored colored pencils can be displayed. In addition, this flap has the effect of reducing the shock of breaking the pencil lead, preventing the stored items from falling out, and preventing the inner box from falling out of the outer box. The flaps may be on the head side only, not on both ends.

Embodiment 3 In Embodiment 1, the partition wall 3 is provided with a dividing portion in addition to the bent portion of the inner box, in the longitudinal center and around 1/4 of the entire length from the end of the tail portion. This dividing part 5 has a deeper bottom than the part with the partition wall, and is on the same plane as the bottom of the outer frame, so that when the inner box is inserted into the sleeve-type outer box 9, this surface comes into contact with the outer box. Become. With this shape, the strength of the inner box is increased, and the stored items in the partitioned compartments can be easily taken out by using the dividing portion.

Example 4 FIGS. 2 and 3 show Example 4. In the case where the inner box of the third embodiment is provided with flaps 8 at both ends, and the number of colored pencils to be stored is large and the inner box becomes long in the horizontal direction, the reinforcing ribs 7 are provided along the vertical direction. Is. The reinforcing rib can be provided at an appropriate position in the lateral direction, but in the present embodiment, it is provided at the center in the lateral direction. This rib has the same shape as the outer frame 2, and is of course divided at the bent portion 6 of the inner box. By providing this rib, the inner box is reinforced, and is not twisted when the inner box is taken in and out of the outer box, and is easy to handle.

[0013]

EFFECTS OF THE INVENTION Regardless of the length of a stored color pencil or the like, backlash can be suppressed, and the stored items can be taken out from the inner box very easily. Also, since it can be manufactured by integral molding with plastic, it is a sturdy case that does not require the complicated work of making and attaching the partition wall as a separate member.
