[0001]

[Industrial applications]

 The present invention relates to a folding container lid as a so-called box that is used when transporting or carrying various products.

[0002]

[Prior art]

 Conventionally, as a foldable container, as shown in Japanese Utility Model Publication No. 55-36350, upper and lower parts are rotatably supported by side edges of an upper frame and a bottom frame, respectively, and foldable at an intermediate part. A foldable side plate container including a first side plate and a second side plate positioned between the first side plate and rotatably supported by the upper frame and the bottom frame at an upper portion and a lower portion is known. ..

In this type of foldable container, a lid covering the upper end opening of the foldable container is attached at the time of assembling or folding to prevent the contained product from jumping out and dust from entering.

[0004]

[Problems to be solved by the device]

 However, the lid attached to the container covers the upper end opening with its side edge engaged with the upper frame, and in order to maintain the attached state, the lid must be fixed to the container with, for example, a fastening band. I had to do it.

When the fastening band is used for fixing, since the fastening band is wound around the outer side surface of the container to which the lid is attached, each end is fastened and fixed, so that the band winding work and the fixing work are performed. Took a long time, and the workability was poor.

The present invention was devised to solve the above-mentioned conventional drawbacks, and the purpose thereof is to cover the upper end opening of the product when it is folded or assembled, and the product is stolen or popped out. It is to provide a lid for a folding container that can reliably prevent the entry of dust and the like.

FIG. 11 is a sectional view taken along line FF of FIG.

FIG. 12 is a perspective view showing an unlocked state.

FIG. 13 is a perspective view showing a locked state.

FIG. 14 is a perspective view showing a state where the container is being assembled.

First, the assembling method of the folding container 1 will be described. In the folded state shown in FIG. 9, each long side plate 7 is erected from the inside to the upper side about the shaft pin 33 so as to face each other. After being lifted, the engaging portions 17 are engaged with the groove portions 29.

In the above state, when the upper frame 5 is lifted upward while the both ends of the long side plate 7 are supported by the first cutout portions 21, the engaging claw portions 29a of the groove portions 29 are engaged with the engaging portions 17.

At this time, since both ends of the long side plate 7 are engaged with the first cutout portion 21 during the lifting, the connection state between the upper frame 5 and the long side plate 7 is maintained.

Further, when the upper frame 5 is lifted upward, the engaging claw portion 29a is engaged with the engaging portion 17, so that the upper frame 5 is prevented from coming out of the long side plate 7.

Next, when the short side plate 9 located between the long side plates 7 in the above state is erected from the inner side to the upper side about the shaft pin 43, the projecting body 37 engages with the second cutout 23. Are combined.

At this time, since the notch 37 a of the projection 37 is locked to the flange 19 and the engaging piece 25 is inserted into the engaging hole 39, the short side plate 9 is maintained in the upright state. ..

When the short side plate 9 is erected, the protrusions 18 formed on both end surfaces of the short side plate 9 engage with the protrusions 16 formed on the inner surfaces of both end portions of the erected long side plate 7. Therefore, the assembled state of the folding container 1 is maintained and the gap formed between the long side plate 7 and the short side plate 9 is closed.

When the lid 10 is attached to the upper portion of the folding container 1 assembled as described above in a state where the operating portions 79a of the locking members 79 move toward each other as shown in FIG. The outer side wall 53 is engaged with the outer side surface of the frame 5, and the inner side wall 55 is engaged with the inner side surfaces of the long side plate 7 and the short side plate 9.

At this time, the inner wall 55 contacting the inner side surfaces of the long-side plate 7 and the short-side plate 9 restricts the rotation return of the long-side plate 7 and the short-side plate 9 to maintain the assembled state.

When the operation portions 79a of the lock member 79 are moved in the above-described state in the directions in which they are separated from each other, the lock portion 79c which is inserted through the notch 57 of the inner wall 55 and moves outward is provided on the long side plate 7. It is inserted into the second lock hole 7f and locked in the first lock hole 5c of the upper frame 5.

At this time, since the upper portion of the engaging protrusion 68 inserted into the opening 77 of the regulating plate 75 projects upward from the upper surface of the regulating plate 75, the hole of the engaging protrusion 68 protruding upward. The return of the regulation plate 75 is regulated by inserting a sealing member (not shown) into 68a.

Next, the folding container 1 assembled as described above is folded by rotating the short side plate 9, the upper frame 5 and the long side plate 7 in the opposite direction to the above-described method.

When the lid 10 is attached to the upper opening of the folded folding container 1 so that the outer side wall 53 thereof is located on the outer side surface of the upper frame 5, the upper opening of the folding container 1 is opened. Will be closed.

Next, when the locking member 79 is moved so that the operating portions 79a are separated from each other in the same manner as the above-described operation, the locking portion 79c is locked in the first locking hole 5c of the upper frame 5. Let

As described above, according to the present embodiment, the closed state of the lid 10 with respect to the upper end opening of the folding container 1 assembled or folded by moving the locking member 79 is maintained, and the stored product is ejected. It is possible to effectively prevent intrusion of dust and the like.

At the time of folding, it is possible to prevent each member constituting the container and the lid 5 from being integrated and prevent them from being separated, and it is possible to easily carry them.

Claim 2 will be described with reference to FIG.

FIG. 15 is an exploded perspective view of the container and the lid.

The container 151 is formed into a box-like shape including first and second side plates 153 and 155 facing each other, the upper surface of which is open and the lower surface of which is closed.

Locking holes 157 as locked portions are formed at predetermined intervals on the inner surface of the upper portion of the first side plate 153 of the container 151, for example.

A lid 10 is attached to the top of the container 151. Since the structure of the lid 10 is the same as that described in the embodiment of claim 1, detailed description thereof will be omitted.

Claim 3 will be described with reference to FIG.

FIG. 16 is an exploded perspective view of the container and the lid.

The container 161 is composed of an upper frame 163, a bottom frame 165, a first side plate 167, a second side plate 169 located between the first side plates 167, and a lid 170.
