[FIG. 8] is a perspective view showing a third embodiment. FIG. 9 is a perspective view showing the third embodiment. FIG. 10 is a cross-sectional view of a main part showing a modification of the third embodiment. FIG. 11 is a perspective view showing the fourth embodiment. The same parts as those in the conventional technique are designated by the same reference numerals.

A first embodiment according to the present invention is shown in FIGS. 1 and 2.
Will be described with reference to. The first embodiment is applied to a case 10 such as a bag. Case 1 like a bag
0 is the opening 1 of the housing 11 formed by the body 12
3 is opened and closed by the lid body 14, and in the present invention, the slit 15 is formed in the lid body 14 at the portion that closes the opening 13. The slit 15 is located at a portion corresponding to the top surface of the case 10 and extends over substantially the entire area in the longitudinal direction. Further, the end portion 16 of the slit 15 is the slit 1
It is cut in the direction perpendicular to 5. Therefore, the piece portion 17 formed by the slit 15 is supported in a cantilever shape and can be easily bent. As shown in FIGS. 2 and 3, the piece 17 of the slit 15 has an inverted “person” shape whose side surface is bent toward the housing 11.

When carrying the case 10, the case 10
The opening 13 is closed by the lid 14. Further, the case 10 is formed of a resin such as polypropylene having appropriate rigidity and elasticity, and the slit 15 is normally in an abutted state due to the elasticity of the resin.

In such a case 10, the object 14 such as a document or the like contained in the accommodating portion 11 can be selected and taken out by opening the lid 14. On the other hand, when the object 1 such as a document is put into the housing portion 11 of the case 10,
As shown by the phantom line, the object 1 such as a document is pushed through the slit 15. In this embodiment, the case 10
Is made of a resin such as polypropylene, and has flexibility, the slit 1
5 is expanded. Then, when the article 1 completely enters the accommodation section 11, the expanded slit 15 collides with the original state.

In this embodiment, the side surface of the slit 15 has an inverted human-character shape in which the slit 15 is bent toward the accommodating portion 11. Therefore, the slit 15 is unlikely to be bent outward by a force from the inside, and the inside of the accommodating portion 11 is difficult. The contained object 1 does not pop out of the case 10. That is, in this embodiment, since the side shape of the slit 15 is an inverted human shape, when the slit 15 receives a force from the inside of the case 10, the slit 15 is deformed in the direction in which the opening becomes narrow. Therefore, due to vibrations or the like generated when carrying the case 10, the contained object 1 inside the case 10 sways, and even if it hits the slit 15, the slit 15 remains closed and the contained object 1 does not come out. .

In this embodiment, the shape of the slit 15 is disclosed as having an inverted "human" -shaped side surface shape as shown in FIGS. 2 and 3, but it is a simple slit as shown in FIG. 4, for example. The end faces of the slit pieces may face each other or face each other with a slight gap. Also slit piece 1
It is also possible to adopt a configuration in which nine comrades overlap each other.

Next, a second embodiment will be described with reference to FIGS. 8 and 9. The second embodiment is applied to a case 20 such as a pen case. Pen case 20
The end face is made of resin and the side face is made of cloth, and the storage part 21 is formed in a bag shape as a whole. Then, the opening 2 is formed on the side surface of the housing portion 21.
3 is opened, and the opening 23 is opened / closed by an opening / closing tool 24 such as a fastener. As a configuration peculiar to the present embodiment, a funnel-shaped cylindrical body 25 is attached to the side surface of the accommodating portion 21. The funnel-shaped tubular body 25 has a diameter-reduced side 26 disposed inside the accommodation portion 21, and an enlarged-diameter end 28 attached to the end surface of the accommodation portion 21. The inner diameter of the reduced diameter portion 27 is made slightly smaller than the diameter of the writing instrument that is the object 2, and preferably the notch 29 is formed. Further, it is desirable that the tubular body 25 be made of an elastic body such as rubber.

In such a pen case 20, when the accommodation object 2 such as a writing instrument is put in the case 20, it is inserted from the cylindrical body 25 of the end face as shown in FIG. Here, since the mounting surface of the cylindrical body 25 adopted in this embodiment is expanded outward, the object 2 can be easily put into the housing portion 21. Even if the inner diameter of the reduced diameter portion 27 of the tubular body 25 is smaller than the outer diameter of the object 2, the reduced diameter portion 27 is formed by forming the tubular body 25 with an elastic body or forming the cut 29. The housed object 2 is expanded in diameter, and the housed object 2 is inserted into the housing portion 21. On the other hand, the storage part 21
Since the inner tubular body 25 has a reduced diameter and is narrow, the to-be-accommodated object 2 in the housing portion 21 does not protrude from the tubular body 25 to the outside of the case 20.

In addition, the reduced diameter portion 27 of the cylindrical body 25 is formed by
Since it projects to the intermediate portion within 1, the writing instrument or the like does not contact the opening of the reduced diameter portion 27 in a normal state. Therefore, the contained object 2 in the case 20 is
Never get out of.

The object 2 to be accommodated in the accommodating portion 21 is the cylindrical body 2.
In practice, there is no problem even if the diameter-reduced portion 27 of the tubular body 25 is made slightly larger than the diameter of the writing instrument as long as it does not protrude from the case 20 to the outside of the case 20. Further, it is possible to exert the effect of the present invention without the notch 29. In the case 10 of the embodiment of FIG. 1, the slit 15 is provided in the lid body 14, but it is of course possible to provide the slit 15 in another portion of the body 12.

Next, a third embodiment will be described with reference to FIGS. Like the second embodiment, the third embodiment is applied to a case 30 such as a pen case. In this case 30, a spring 35 is attached to an abutting portion 34 of an opening 33 opened on the side surface of a bag-shaped accommodating portion 31. The spring 35 is a leaf spring or a spiral spring, and urges the opening 33 to close. Figure 10
Shows an example in which a leaf spring is adopted as the spring 35,
The leaf spring has a cross-sectional shape in which the direction on the opening side is arcuate. Therefore, the distance between the two leaf springs 35 widens toward the outside.

In the case of this embodiment, the opening 33 is normally closed by the spring 35 or has a slight gap. In the present embodiment, when the accommodation object 3 such as a writing instrument is put into the storage portion 31, the accommodation object 3 is pushed into the opening 33. That is, in the case 30 of the present embodiment, the leaf springs 35 have an arc-shaped cross section, and the gaps between the leaf springs 35 widen toward the outside, so that when the object 3 is pressed against the opening 33. , A force is generated in the direction of separating the leaf springs 35 from each other.

Therefore, when the object 3 is pushed in, the spring 35 bends and the opening 33 is expanded by the width of the object 3. When the to-be-contained object 3 is put into the accommodation section 31, the opening 33 is closed by the leaf spring 35. Of course, the spring 35 is forcibly bent by a finger or the like,
If the opening 33 is opened wide, a large number of objects 3 can be put in the accommodation part 31 at one time.

The present invention is not limited to the above-mentioned three embodiments, and the design can be changed within the scope of the present invention. For example, as shown in FIG. 7, a slit 42 may be formed at the upper end of a rectangular parallelepiped case 40 having a door 41, and the plate member 4 such as a flexible disk may be inserted through the slit 42. Since the plate member 4 can be put into the case 40 without opening the door 41, the plate member 4 such as the flexible disk is not scattered on the desk.

In the above embodiments, the case in which the slit is provided in the bag-like case is illustrated, and the case in which the case is provided with the cylindrical body is also illustrated. However, the shape of the case and the combination of the slit and the cylindrical body are arbitrary, and the cylindrical body 25 adopted in the embodiment of FIGS.
Can also be attached, and a slit can be provided in a bag-shaped case as shown in FIGS. When the slit is provided in the bag-shaped case, it is desirable to mold the end surface of the case with resin to maintain rigidity to some extent and to provide the slit in the end surface.

[0034]

According to the present invention, it is possible to put an object such as a document or a writing instrument into the accommodation portion through the slit or the cylinder without opening the opening, so that the convenience is improved. .
