Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container hinge device for connecting the bottom and lid of the container in an openable and closable manner.

For example, a metal container such as a pencil case whose lid is opened and closed by a hinge device usually has a bottom, a lid, and one or two pins as a shaft to connect them.
It is composed of more than one member.

However, the presence of this pin necessitates the addition of several manufacturing steps, which poses a problem that affects the manufacturing cost of the container.

Further, in many cases, this pin is generally attached from the inside of the bottom, and with this structure, it is almost impossible to fill the bottom with articles before attaching the lid.

Therefore, it is necessary to fill the container with the lid after assembly, making it extremely difficult to use an automatic article filling device.

The present applicant has already proposed in Utility Application No. 55-25488 that the bottom part and the lid part are connected without using a pin, and a part of the lid part has two parts.
A hinge device for a container has been proposed in which protruding shafts of different lengths are formed by rolling the metal plate of the lid so that the lid can be easily attached even after filling an article.

Although this hinge device was found to be extremely effective for its intended purpose, it did tend to lack the strength of the projecting shaft in larger containers.

Therefore, although the present invention uses a pin, it is possible to attach the lid to the bottom after filling an article, and the purpose of the present invention is to provide a hinge device for a container with a simple structure. It is made up of three types of parts: the lid and the pin,
In a container in which the lid portion is opened and closed by connecting the connecting portion between the bottom portion and the lid portion with the pin, the side wall serving as the connecting portion of the lid portion is extended downwardly longer than the peripheral edge of the other side wall of the lid portion. It extends into a bent part whose end edge is formed into a tubular shape, and the pin is inserted into the bent part to form two protruding shafts of different lengths which protrude in the horizontal direction at both ends of the bent part. provided, said pin consisting of two
Among the two protruding shafts, the length of the longer protruding shaft is approximately twice the length of the shorter protruding shaft, and the length of the longer protruding shaft is approximately twice that of the shorter protruding shaft. distance,
The length from the root of the long protruding shaft to the tip of the short protruding shaft is slightly larger, and the two protruding shafts are rotatably fitted into the two shaft holes. .

The present invention will be explained in detail based on illustrated embodiments.

FIG. 1 shows a perspective view of the bottom 2 and lid 3 of the container before they are connected.

The hinge device functions by combining connecting parts 6 and 7 provided on the side walls 4 and 5 of the bottom part 2 and the lid part 3, which are formed based on metal plates.

In the lid part 3, the connecting part 7 extends downward wider than the peripheral edge 9 of the other side wall 8, and a step is provided between the connecting part 7 and the peripheral edge 9, and the end edge of the connecting part 7 is formed into a rounded tubular shape. The curved portion 10 is curved.

A pin 11 made of a metal rod serving as a connecting member with the bottom portion 2 is inserted and fixed into the bent portion 10, and both ends thereof serve as protruding shafts 11a and llb that protrude outward.

The lengths of these protruding shafts 11a and 11b are different, and when they are lined up, the length of the protruding shaft 11b is adjusted to be about twice that of lla.

On the other hand, in the connecting part 6 of the bottom part 2, a groove 12 recessed inwardly is provided in the horizontal direction as required, and horizontal ridges i3a and 13b bulging outward are formed at both ends of the groove 12. , shaft holes 14a and 14b are provided at the boundary between the groove 12 and the ridges 13a and 13b, respectively.
The protruding shafts 11a and 11b of the lid portion 3 are rotatably fitted into the ridges 13a and 13b via the ridges 4a and 14b, respectively.

To fit the protruding shafts 11a and llb into the shaft holes 14a and 14b, insert the protruding shaft 11b on one side into the shaft hole 14b on one side, and then insert the protruding shaft 11a on the other side into the remaining shaft hole 14a. For this reason, the protruding shaft 11b protrudes longer than the protruding shaft 11a on the other side.

That is, for example, the protruding shaft 1 on the other side from the root of the protruding shaft 11b
The length 11 to the tip of 1a is the shaft hole 14a of the bottom 2, 1
It must be slightly shorter than the length 1□ of comrade 4b.

Note that the notches 15a and 15b provided above the protruding shafts 11a and llb prevent the peripheral edge 9 from coming into contact with the ridges 13a and 13b when the lid is opened when the difference in level between the connecting portion 7 and the peripheral edge 9 is small. This is to prevent

Therefore, with the lid 3 wide open relative to the bottom 2, the protruding shaft 11b is deeply inserted into the ridge 13b through the shaft hole 14b of the bottom 2 until the root of the protruding shaft 11b reaches the shaft hole 14b. When inserted, the tip of the protruding shaft 11a on the other side is located at the entrance of the shaft hole 14a on the other side.

Therefore, by slightly moving the connecting portions 6 and 7 horizontally in opposite directions so that the protruding shaft 11a enters the shaft hole 14a, a connected state as shown in FIG. 2 is obtained.

In this case, since the protruding shafts 11a, flb are provided with a step between them and the peripheral edge 9 of the other side wall 8, the protruding shafts 11a, lb are provided with a step.
lb is not obstructed by the peripheral edge 9 and the shaft holes 14a, 14b
The container can be easily inserted into the container, and the hinge device itself does not protrude significantly outside the container, which is convenient.

Moreover, once the connected state as shown in Fig. 2 is obtained,
Since the tip of the protruding shaft 11b lightly contacts the inner part of the ridge 13b, the lid part 3 will not be inadvertently moved in the horizontal direction even when the lid is opened.

The present invention is not limited to the above-mentioned embodiments,
Many variations are possible within the scope of the utility model registration claim.

For example, the bottom part 2 and the lid part 3 do not necessarily need to be made of metal, and may be made of synthetic resin without any problem.

In addition, pins 11 made of synthetic resin can also be used, and instead of inserting one pin 11 into the bent part 10, it is recommended to insert shorter pins one by one from both sides of the bent part 10. You may also do so.

Furthermore, the pin 11 may be attached to the lid part 3 by welding, gluing, or other means other than insertion and fixation into the bent part 10.

As described above, the container hinge device according to the present invention has two protruding shafts of different lengths made of pins at the connection part of the lid, and a step is provided between the protruding shafts and the other side wall periphery. This makes it possible to fit the lid into the shaft hole at the bottom so that it can be opened and closed, reducing manufacturing costs, and reducing the work of filling goods because the lid can be attached after filling the bottom with goods. This has the advantage of improving efficiency.
