Abstract

A box-shaped bag capable of being varied in thickness, wherein two frame bodies formed of plastic in rectangular shape are connected openably to each other through hinge pins (12), shells are formed of plastic in disk shape and the peripheral edges of the shells are folded back outward in U-shape, and grooves are formed around the frame bodies so that, when the shells are fitted to the frame bodies, the folded back parts of the shells are just fitted into the grooves of the frame bodies.

Description

Technical bag Technical field

The present invention relates to a box-shaped bag to which a shell can be replaced.

Background art

In a box-shaped bag such as an attache case, a shell is fixed to a pair of frames whose lower parts are pivotally supported. Such a box-shaped bag cannot be easily crushed even if it is pushed, so documents can be safely inserted.

However, the capacity of a box-shaped bag cannot be changed (thickness), so it may be too large or too small depending on the intended use. In addition, some bags are provided with a special partition in the bag to store specific items.However, such a bag with a partition has the disadvantage that it is difficult to store items with different shapes and dimensions. . For this reason, several bags are arranged, and it is difficult to place them. Disclosure of the invention

Therefore, an object of the present invention is to provide a bag that can easily replace a shell.

The bag according to the present invention has a configuration in which a dish-shaped shell is detachably fitted from the inside to a pair of frames that can be freely opened and closed by pivotally supporting the lower portions of each other.

As described above, the bag of the present invention has a configuration in which the shell is detachably fitted into the frame, so that several types of shells having different thicknesses and colors, and a shell with a partition are prepared. By replacing those shells, you can get a bag that suits your purpose. Therefore, there is no need to have several bags, and less storage space is required.

The shell removed from the frame can also be used as a storage tray for storing objects. Objects stored in the tray (shell) can be carried around without being refilled by simply inserting the shell into the frame.

Preferably, the periphery of the shell is folded outward in a U-shape, and a groove is formed around the frame. The shell is configured such that the folded portion of the shell fits into the groove. In this way, the frame is not distorted by being fitted with the shell, and when the bag is closed, the pair of azure bodies are staggered and do not conflict with each other.

Further, it is preferable that recesses are formed at regular intervals on the inner surface of the shell, and projections provided on the bottom of a partition or an accessory case are fitted to these recesses in correspondence with the recesses to fix the partition. With this configuration, objects can be tightly stored in the bag using fixed partitions.

BEST MODE FOR CARRYING OUT THE INVENTION

One embodiment of a bag according to the present invention is shown in FIG. In this embodiment, as shown in the figure, the shell 11 is configured to be removably fitted to the frame 10. The frame 10 is made of plastic and is formed in a rectangular shape. The two frames are connected to each other with hinge pins 12 so as to be freely opened and closed. The 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 fit or fit in 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 into the groove 17 of the frame as shown by the chain line in FIG. 2.

In order to prevent the fitted shell 11 from easily falling out of the frame 10, small protrusions are formed at a plurality of predetermined places in the groove 17 of the frame 10 and the folded portion 16 of the shell 11. Claws 19 are provided so that when the shell is fitted, one claw 19 gets over the corresponding opponent's 19 claw. The shell 1 1 fitted in this way has claws 1 9 Because they get caught in each other, they cannot easily come off from Azusa body 10. To remove shell 11 from azusa body 10, press shell 11 strongly from outside to inside. In this way, one nail 19 gets over the other nail 19 and the seal 11 comes off.

FIG. 3 shows a state in which the shell 11 is fitted into the frame 10 in this manner. Figure 4 shows the bag closed.

The shells shown in these drawings are of standard depth, so if you want a thicker bag, remove the shell of standard thickness and replace it with a shell of greater depth (not shown).

When the seal 11 is formed, at the same time, a recess 20 is formed on the inner surface of the shell at regular and horizontal intervals. Using this recess 20, a partition plate, booth storage, etc. are attached. That is, as shown in FIG. 5, a projection 21 is provided at the lower part of the partition plate (or accessory case) 22, and the projection is fitted into the recess 20 so as to be fixed. The entrance of the depression 20 is made narrow so that the projection does not come off easily.

Industrial applicability

As described above, according to the configuration of the present invention, the shell of the bag can be easily replaced, and the bag can be used according to the intended use such as thickness and color.

Although the present invention has been described with reference to preferred embodiments, it should be understood that the invention is not limited to those details. It is to be understood that the invention does not depart from the spirit and scope of the appended claims, and encompasses variations that would become apparent to those skilled in the art to which the invention pertains.
