JPS5917780Y2 - packaging box connector - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a connector for packaging boxes such as cardboard boxes.

In the past, various types of connectors for packaging boxes have been devised.
Although it has been put into practical use, the most typical type of connector is, for example, the type that connects a half-A type cardboard box and a bottom box by inserting them into holes provided at corresponding positions. When using, to make a hole in the box,
Particularly in the case of small-lot production, the number of man-hours increases and costs are disadvantageous.

In addition, in the case of hand cargo handling, since the package is transported through hand holes, the weight of the package is concentrated at the joint hole, which has the disadvantage of damaging the hole.

For this reason, reinforcing paste is required.

The present invention eliminates the above-mentioned disadvantages and provides a coupling tool that is particularly advantageous for coupling a half-A type corrugated cardboard box and a bottom box in the case of heavy goods packaging.

Hereinafter, the present invention will be explained in detail with reference to examples thereof.

FIG. 1 is a front view showing an embodiment of the coupling tool of the present invention, and FIG. 2 is a longitudinal sectional view thereof.

In these figures, reference numeral 1 denotes a collar portion with a hand hole 2 provided in the center, and the edge of the hand hole 2 is constituted by a cylindrical piece 3.

Numerals 4 and 5 are locking protrusions that protrude from opposite edges of the hand 7L2 along the flange in directions away from each other; 6 is an operating piece that extends from the base of the protrusion 4 toward the hand hole; 7, 7 are grooves formed by cutting into the flange from both ends of the base of the projection piece 4.

Reference numeral 8 denotes a band locking portion provided on the side of the collar portion 1 having the projecting piece 5, and has three band insertion holes 9.

The connector 10 is made of a relatively elastic material, such as a synthetic resin such as polypropylene.

Next, in order to connect the semi-A type cardboard box 11 and the bottom box 12 using this connector 10, as shown in FIG. 3, attach the connectors 10 to the hand holes provided on both sides of the box 11. Both ends of the band 13 are fastened to the band locking parts 8 of the coupling tool, and the boxes 11 and 12 are connected by the band.

To attach the coupling tool 10 to the hand hole of the box, insert the locking protrusion 4 into the inside of the box through the hand hole 14 of the box, and then insert the operating piece 6 toward the front side as indicated by the arrow hole in Figure 2. Fold it down, raise the protrusion 5 upward, and insert it into the hand hole 14.

Thus, the coupling tool 10 is coupled to the edge of the hand hole 14 of the box by the collar 1 and the projections 4 and 5.

Note that the band 13 may be connected to the coupling tool 10 by a method other than that shown in the drawings, but if the locking portion 8 is provided with three holes 9, these holes can be connected as shown in FIGS. 4 and 5. It is convenient because it can be firmly joined by simply passing the band through.

As mentioned above, the coupling device of the present invention is provided with protrusions 4 and 5 on opposite edges of the hand hole 2 for locking into the hand hole of the packaging box, and one protrusion 5 side is provided with the protrusions 4 and 5 for engagement with the hand hole of the packaging box. The pieces 6 are arranged in a row, and the grooves 7 are
, 7, the projecting piece 5 can be moved by the operating piece 6 and easily attached to and removed from the hand hole of the box.

In addition, when a semi-A type box and a bottom box are combined together with a band as shown in Fig. 3, the weight of the packaged items is applied to the band through the bottom box, so when handling cargo, it is necessary to use the binding tool 10. It joins the hand holding hole 2 and does not join box 11 at all.

Therefore, there is no damage to the hand holes of the box, and there is no need for reinforcement.

Furthermore, since the coupling tool is attached to the hand hole of the box, there is no need to create a new hole for coupling.

The coupling tool of the present invention is most effective when used to join half-A type corrugated boxes and bottom boxes that are used for hand cargo handling, but it can also be used for packaging boxes that open at the top or open at the front. Needless to say, it can be used for things such as sealing.

Although the operating piece and the groove are provided on the side having the protruding piece 5 on the upper side, they may be provided on the other protruding side.

As described above, the coupling device of the present invention is of great practical value, as it is easy to attach and detach from the packaging box, can be reused, and does not damage the box itself during cargo handling.
