DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding opening / closing lid stopper which can be easily closed and fixed without taping such as a cardboard box.

[0002]

2. Description of the Related Art In order to securely fasten a folded openable cover such as a cardboard with a seal, it is customary to close and seal the cover with various tapes.

[0003] By the way, corrugated cardboard is used in different ways depending on various uses and is not uniform.

[0004] There are a case where the folded opening / closing lid capable of closing the opening is used while being folded, and a case where it is completely shielded by using a tape.

[0005]

In the work of shipping such as bins and indulgences, those with a long shelf life are commercialized, stored in a cardboard box, stored, and printed, etc. at the time of shipping. In the case of foodstuffs, it is necessary to temporarily stop by taping to prevent dust, garbage, etc.,
When removing the items from the cardboard box again, the attached tape must be peeled off, and at this time, the surface of the folded open / close lid of the cardboard is peeled off and the surface is scratched and cannot be used again. There is an inconvenience.

In order to eliminate such inconveniences, when the tape is stored without taping, when the cardboard lid has a higher strength, the lid part is lifted up, and as the height of the lid is increased in two or three stages, the lid becomes higher. However, there was a problem that the stacking became impossible as one went up.

[0007] By the way, there is known a cardboard box called a box (return box). This box is used for transporting the contents and currently uses strong cardboard, and the lid must be closed. If it is necessary, tape is attached and transported, but on the receiving side, the tape is peeled off, the contents are taken out, and then folded back to the other party.

[0008] However, in the case where the taping operation is carried out, the surface of the folded open / close lid is peeled off by repeatedly attaching and detaching the tape, and gradually becomes thinner, and the function as the lid disappears. There is an inconvenience that the tape cannot be used after repeated taping.

[0009] When storing and shipping commodities including general foods and the like, in order to prevent dust, dust and foreign matter from being mixed, cheap cardboard made of cheap paper is used, and almost all of them are thrown away.

[0010] In addition, in the case of storing goods in the home,
The tape is used with the folded open / closed lid closed by sticking tape using corrugated cardboard, and a wasteful operation of peeling off the tape every time the lid is opened is forced.

Although the above are mainly the problems and disadvantages relating to cardboard, the same disadvantages and disadvantages can be seen when taping a box other than a cardboard having a folding open / close lid.

The present invention has been made by paying attention to the points described above, and provides a stopper for a folding opening / closing lid which can be used repeatedly without such taping and which has an excellent appearance. The purpose is to:

[0013]

The present invention can solve the above-mentioned problems by providing the following constitution.

(5) The stopper according to the above (1) or (2), wherein the upper stopper and the lower stopper have substantially the same width.

(6) The width of the lower stop portion is substantially the same as the length between the two bent base portions of the pair of bent open / close lids of the box. Stopper for folding lid.

[0020]

Embodiments of the present invention will be described below with reference to several examples.

FIG. 1 to FIG. 3 show the most typical examples of the stopper for the folding lid according to the present invention.

In the drawings, reference numeral 1 denotes an upper stopper, 2 denotes a lower stopper, and the upper stopper 1 is formed in the center in a tongue shape a.
Is formed in a frame shape at an interval 1 around the outer periphery of the upper stopper 1, and the distance g between the upper stopper 1 and the lower stopper 2 is a desired box, for example, a pair of cardboard boxes A. The folded lids B, B have a thickness substantially equal to or slightly smaller than the thickness h of the folded lids B, so that the base part 3 can connect and hold the two parts 1, 2. In this embodiment, the base 3 is formed as a hanging part 4 extending downward at a substantially right angle to both parts 1 and 2 by extending the base 3 downward.

The width W of the lower stop 2 is substantially the same as the distance H between the bent bases of the pair of bent lids B of the box A.

The operation will be described based on the configuration described above.

A pair of folded opening / closing lids B, B are folded as shown in FIG. 4 with respect to a pair of folding opening / closing lids provided inside the opening of the box A, and the lid is completely closed. The upper stopper 1 and the lower stopper 2 are inserted into the pair of opposed folding lids B, B from the sides of the pair of folding lids B, B in the closed state, as shown in FIG. Fixed to.

Although it is permissible to fasten the pair of folded lids B, B from one side, it is better to use two fasteners from both sides as shown in FIG. .

Since the gap g between the upper and lower stoppers 1 and 2 is substantially equal to or slightly smaller than the thickness of the folding lids B, B, the pair of folding lids B, B are securely connected. Since the upper stopper 1 is sandwiched and formed in the shape of a tongue piece a, it can be pressed down along the opposing edges B ₁ , B ₁ of the pair of folding open / close lids B, B adjacent to each other. And the hanging part 4 is locked with the upper part C of the box A, so that the locking of the stop piece can be further strengthened.

Thus, the box lid is securely locked and closed by the simple locking means of the stopper without taping as is conventionally done with tape or the like, so that not only inventory management but also shipping is performed. Can be transported.

Next, an embodiment shown in FIG. 7 will be described.

In this embodiment, the hanging part 4 is removed from the fastener shown in the above embodiment, and only the base 3 supporting the upper and lower stoppers 1 and 2 is provided.

Also in this case, the same action as described above is exhibited, and the pair of folding open / close lids B, B of the box A are connected to the upper and lower stoppers 1, 2.
Can reliably hold the closed state.

Further, each embodiment of FIGS. 8 to 11 will be described.

In any of the embodiments, basically, an upper stopper 1 and a lower stopper 2 are provided, and the distance g between the upper and lower parts 1 and 2 is substantially the same as the inner thickness h of the lid of the box A. In that the width W of the lower stop 2 is substantially the same as the distance H between the bent base portions of the pair of folded open / close lids B, B of the box A. Are identical.

However, each of the embodiments has a structure in which the upper stopper 1 and the lower stopper 2 are vertically overlapped with the same size, and a part of the center of the upper stopper 1 is tongue-shaped. FIGS. 8 and 9 show the case of “a”, and FIGS. 8 and 10 show slightly different structures in which the hanging portion 4 is connected to the base 3. In any case, the box A can be securely fastened to the pair of folded open / close lids B, B, and the closed state can be ensured.

Although not shown, the upper stopper 1 and the lower stopper 2
The sizes of the upper and lower stoppers 1 and 2 may be different.
Therefore, it is necessary and important to provide both stoppers 1 and 2 with a size that can securely hold the pair of folding open / close lids B.

Further, if necessary, an elastic effect can be imparted to the upper stop 1 and the lower stop 2 with respect to the base 3 in order to enhance the clamping effect. In this case, it can be achieved by molding the material of the stopper piece with metal or plastic.

[0037]

According to the present invention, the means for closing the lid of the opening of the corrugated cardboard box, which has conventionally been indispensable for taping, involves the inconvenience that the lid is peeled off the surface by the engagement and disengagement of the stopper having a simple structure. It can be used repeatedly without the use of the cardboard, so that it is possible to use the cardboard for a long time and to use the cardboard without losing the beauty of the open / close lid of the box. In addition, the present invention can be similarly applied to a bent openable / closable lid of a hard box other than a cardboard box, and can be mass-produced at low cost with a desired material such as metal or plastic.
