Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a packaging stopper that also serves as a handle.

Conventional Structure and Problems Generally, packaging boxes for heavy goods are divided into an upper box 1 and a lower box 2, as shown in FIG. 1, to facilitate manufacturing. The upper box 1 and the lower box 2 are bound and packed with a string-like body 3, but there is a problem that the string-like body 3 stretches and loosens. Moreover, if the string-like body 3 is cut when unpacking, the string-like body 3 cannot be reused.

Furthermore, although a handle hole 4 is provided in the cardboard box as shown in FIG. 2, the handle hole 4 is easily torn. For this purpose, a reinforcing handle (not shown) is provided in the handle hole 4, but this reinforcing handle has a hole for inserting the hand, and dust enters through this hole, which is inconvenient for packaging precision instruments.

Purpose of the Invention The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to provide a packaging stopper that can easily connect and unpack an upper box and a lower box, and can be used as a handle with a dustproof function during transportation. This is the purpose.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a hook member that is fitted into a hole in a packaging box, is provided in a cylindrical portion via a hinge, is hooked to the edge of the hole, and is held between the flange of the cylindrical portion and the hook member. It consists of a fixed base body and a cylindrical key body that is inserted into a cylindrical part of the base body to push and spread the hook member, and the opening is closed and a hand is inserted into the cylindrical part of the key body. This packaging stopper is equipped with a closing plate that can be pushed open by the user, and in addition to functioning as a stopper, the packaging stopper also functions as a handle, and the hole where the hand is inserted is normally It has the unique effect of being blocked and effective in preventing dust.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 to 8.

In the figure, the packaging stopper consists of a base body 5 and a key body 6. The base body 5 has a cylindrical portion 7
A flange portion 8 provided at one end edge of the cylindrical portion 7 and a hinge portion 9 on the opposing inner wall of the cylindrical portion 7, respectively.
It consists of a pair of hook members 10, 10 with an L-shaped cross section connected via a There is. The key body 6 is a cylindrical portion 7 of the base body 5.
It consists of a cylindrical part 12 that fits the cylindrical part 12 and a closing plate 13 that is partially connected to one end of the cylindrical part 12 and closes the hole of the cylindrical part 12. It is connected to the opposite end by a connecting piece 4. A locking protrusion 15 is provided on the outside of the end of the key body 6 opposite to the connecting piece 14, and a knob piece 16 is provided in a protruding manner. Each of these constituent members is made of flexible and bendable polypropylene.

As shown in FIG. 6, the packaging fasteners having the above structure include the plate body 17 of the upper box and the plate body 18 of the lower box which are stacked on top of each other.
The cylindrical part 7 of the base body 5 is connected to the communicating holes 19 and 20.
Insert. Next, the key body 6 is bent at its connecting piece 14, and its cylindrical portion 12 is inserted into the cylindrical portion 7 of the base body 5. At this time, the cylindrical portion 12 of the key body 6 presses the hook members 10, 10 provided inside the base body 5, and the hook members 10, 10
rotates about the hinge part 9 as a rotation fulcrum, and the tip piece engages with the lip of 18 at the inner position. Then, the two plates 17 and 18 are tightened by the flange 8 of the base body 5 and the hook members 10 and 10. Note that the locking protrusion 15 of the key body 6 is connected to the locking portion 11 of the base body 5.
, and the key body 6 is fixed to the base body 5.

7 and 8 show the state in which the packaging fastener of the above embodiment is used to connect the upper box 21 and the lower box 22. FIG.

When the packaging stopper is attached, the closing plate 13 of the key body 6 closes the hole of the cylindrical part 12 at the inner part of the cylindrical part 12,
The cylindrical part 12 prevents dust from entering. When the packaging stopper is used as a handle, there is no problem because the closing plate 13 can be pushed open backwards by inserting a hand, and the packaging stopper can be used to close the holes in the plates 17 and 18. The pore edges of 19 and 20 are protected.

Note that the tip of the cylindrical portion 12 of the key body 6 is
As shown in FIG. 6, it is preferable to provide a step so as to partially overlap the hook members 10, 10, thereby reducing the cylinder diameter. Further, although the base body 5 and the key body 6 are connected by the connecting piece 14, they may be independent, and the base body 5 and the key body 6 may have a rectangular shape other than an oval shape. .

Effects of the Invention As is clear from the description of the embodiments above, the packaging fastener of the present invention can function as a packaging box connector and a handle, and is easy to attach and detach. When it is attached, the hole for inserting the hand is blocked by a blocking plate, making it difficult for dust to enter.When used as a handle, the blocking plate can be pushed open by hand, so there is no problem, and it is of great value. be.
