Description

[Detailed Description of the Invention] The present invention relates to a packaging fastener, and its purpose is to make it easy to assemble and unfold the packaging 9 of a container.

In general, packaging fasteners are often fastened with staple pull needles, which have the drawback that when the packaging box is unfolded, the staple pull needles are removed, c'-<<, and the packaging box is damaged.

For this reason, as shown in FIGS. 9 to 11, a pair of U-shaped clamp portions 1. A connecting piece 2 that connects these U-shaped clamp parts 1 and 1', a hinge part 3 in the center of the connecting piece 2 to make it freely bendable, and a clamp part 1,
A packaging fastener A consisting of a support piece 4 inserted between 1' and 1' was developed, and a hole corresponding to the two members 5 and 5' of the box to be joined was formed, and the packaging fastener A was We have considered a method in which the members 5, 5' are joined by inserting the member 5, 5' in a pre-bent state into the hole, and then extending the connecting piece 2, thereby clamping the edge of the hole with the clamp parts 1, 1'. .

By the way, in this case, the packaging stopper A can be easily attached and detached, but the shape is large and complicated, and the hole to be made in the box is also large.

The present invention takes these points into consideration and eliminates the drawbacks, and will be explained below based on FIGS. 1 to 4 showing one embodiment.

In the figure, 6 is a cylindrical body made of synthetic resin such as polypropylene, and integrally has a flange 7 in its midsection.

Face plates 8, 8' are provided at both ends of the body 6, and a pair of fin pieces 9, 9 and 9' are provided on the face plates 8, 8', respectively.
9' is provided so as to be freely inverted via hinge parts 10, 10, 10', 10'.

The face plates 8, 8' of the body 6 have fin pieces 9, 9.9', 9.
Lock protrusion 11.11.1 to be located on the outer part of '
1', 11' are provided, and the fin pieces 9, 9.9'
, 9' has the lock protrusion 11, 11° 11',
Lock holes 12, 12.12 that fit and connect with 11'
'.

12' is provided, and this lock protrusion 11, 11.11
', 11' and the locking holes 12, 12.12', 12' form a locking part between the body part 6 and the fin pieces 9°9.9', 9'.

The fin pieces 9, 9.9', 9' protrude outside the body 6 when folded down, and the folded fin pieces 99, 9', 9 and the collar 7 Two sets of clamping parts are configured.

The thickness of the clamping parts of the two pairs of clamping parts is approximately equal to the thickness of the packaging box, which will be described later.

The packaging fastener constructed as described above is used as follows.

That is, the two plate-shaped members 13.13' of the packaging boxes to be joined are provided with mounting holes 14.14 that coincide with each other in advance.
', first insert one fin piece 9.9 of the packaging stopper and a part of the body 6 into the mounting hole 14 of the first member 13, and then fold down the fin pieces 9, 9. As a result, the edge of the mounting hole 14 of the first member 13 is sandwiched between the fin pieces 9 and the collar 7 (see FIG. 2).

Next, the other fin pieces 9', 9' and a part of the body 6 are inserted into the mounting holes 14' of the second member 13, and by folding down the fin pieces 9, the second member 13' The edge of the mounting hole 14' is sandwiched between the fin pieces 9', 9' and the collar 7.

When the fin pieces 9°9.9', 9' are in the folded state, the locking holes 12°12.12', 12' are fitted into the locking protrusions 11, 11, 11', 11'. , this packaging fastener allows the first. The second member 13.13' is connected (see FIG. 3).

Note that FIG. 4 shows the packaging stopper with the fin pieces 9, 9.9', and 9' folded down.

Figures 5 and 6 show another embodiment of the invention, which connects three members 13, 13', 13''.

For example, the third member 13'' is the end of a partition plate provided in the box and is simultaneously joined by a packaging fastener when the box is assembled.

In this embodiment, the collar 7 is located at a position slightly offset from the center of the body 6, that is, one member 13' is placed on the negative side and the first member 13' is placed on the other side. A third member 13.13'' can be placed.

7 and 8 show an example in which the packaging fastener of the present invention is used for assembling a box, and FIG. 7 shows an unfinished state in which the packaging fastener is attached to one member 13; The figure shows the completed state in which the second member 13' is joined.

As is clear from FIG. 7, even when the box is in an unassembled state, ie, in a state where the box can be folded, there is no need to remove the packaging stopper.

As explained above, the packaging fastener of the present invention has fin pieces that can be turned upside down at both ends of the body, and the fin is provided in the center of the body. It has two sets of clamping parts to connect two or three members, and since the collar carries part of the load, there is no chance of the fins being cut, and it is possible to connect two or three members to one member. Since it can be temporarily fastened, there is no need to completely remove the packaging fasteners when unfolding the box, making it a good product to use.
