Abstract

PROBLEM TO BE SOLVED: To provide a boxlike bag that uses easily replaceable shells. SOLUTION: Two square frames 10 molded in plastics are interconnected via hinge pins 12 for free opening and closing. Dished shells 11 molded in plastics each have outwardly U-bent edges. The frames 10 are each, on the other, grooved along the edges. When the shells 11 are placed in the frames 10, the shell folds fit in the frame grooves perfectly.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box bag to which a shell can be replaced.

[0002]

2. Description of the Related Art In a box-shaped bag represented by an attache case, a shell is fixed to a pair of frames whose lower parts are pivotally supported. Such a box-shaped bag does not easily collapse even when pressed, so that documents and the like can be safely inserted.

[0003]

However, since the capacity (thickness) of a box-shaped bag cannot be changed, it may be too large or too small depending on the intended use at that time. In addition, a special partition may be provided in a bag to store a specific object. However, such a bag with a partition has a disadvantage that it is difficult to store other objects. For this reason, I will have a lot of bags,
You will be in trouble with the place. Therefore, an object of the present invention is to provide a bag in which a shell can be easily replaced.

[0004]

In the bag of the present invention, a dish-shaped shell is detachably fitted from the inside to a pair of frames which can be opened and closed by pivotally supporting the lower portions of the bag (claim 1). As described above, the bag of the present invention is configured such that the shell is detachably fitted into the frame body, so that several types of shells having different thicknesses and colors, as well as shells with partitions are prepared, and the shell is prepared. By changing the number, it is possible to obtain a bag according to the intended use at that time. Therefore, it is not necessary to have several bags, and the storage space is reduced.

The shell removed from the frame can be used as a storage tray for storing objects. The items stored in the tray (shell) can be inserted into the frame as it is,
You can carry around without refilling.

Preferably, the periphery of the shell is folded outward in a U-shape, a groove is formed around the frame body, and the folded portion of the shell is fitted into the groove. . By doing so, the distortion of the frame body is eliminated by fitting with the shell, and when the bag is closed, the pair of frame bodies fit together, and no misalignment occurs.

If recesses are formed at regular intervals on the inner surface of the shell, projections provided on the bottom of the partition or accessory box can be fitted into these recesses to fix the partition. There is no need to have a hollow, but if you do, you can use the dividers to keep things in your bag.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, this bag has a shell 10 detachably fitted into a frame 10 as shown in FIG. The frame 10 is made of plastic and is formed in a rectangular shape, and two of them are joined together by hinge pins 12 so as to be freely opened and closed. A handle 13 is formed integrally with the frame 10. Reference numeral 15 denotes a slide-type stopper that holds the pair of frames 10 so as not to open.

The shell 11 is made of plastic and is shaped like a dish, and has a size that can be easily fitted into the frame 10. As shown in FIG. 2, the periphery of the shell 11 is folded outward in a U-shape (the folded portion is indicated by reference numeral 16). On the other hand, a groove 17 is formed around the frame 11. When the shell 11 is fitted into the frame 10, the folded portion 16 of the shell fits exactly into the groove 17 of the frame, as shown by the chain line in FIG.

In order to prevent the fitted shell 11 from easily falling out of the frame 10, small claws 19, which are small projections, are provided in the groove 17 of the frame 10 and the folded portion 16 of the shell 11, so that the shell is mounted. At the time of fitting, one of the claws 19 is made to get over the corresponding mating nail 19. The shell 11 thus fitted cannot be easily removed from the frame 10 because the claws 19 are hooked. When detaching the shell 11 from the frame 10, the shell 11 is strongly pushed inward from the outside. In this case, one of the claws 19 gets over the other's claws 19 and the shell 11 comes off.

FIG. 3 shows a state in which the shell 11 is fitted into the frame body 10 in this manner. FIG. 4 shows a state in which the bag is closed. The shells shown in these figures are of standard depth, so if you want to make your bag thicker, remove the shell of standard thickness and replace it with a shell of greater depth (not shown).

When the shell 11 is formed, at the same time, the recesses 20 are provided on the inner surface of the shell at regular and horizontal intervals.
To form A partition plate, a booth compartment, and the like are attached using the recess 20. That is, as shown in FIG. 5, a projection 21 is provided at a lower portion of a partition plate (or a booth) 22, and the projection 21 is fixed by being fitted into the recess 20. The entrance of the recess 20 is made narrow so that the projection does not come off easily.
