Description

[Detailed Description of the Invention] 2. Field of Industrial Application The present invention relates to a packaging stopper that also serves as a handle, and is divided into a lower box 2 and a lower box 2 to facilitate manufacturing.
The lower box 2 is 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.
This is inconvenient for packaging precision equipment.

Purpose of the Invention The present invention takes into consideration the above-mentioned conventional problems, and provides a method for combining an upper box and a lower box,
It is an object of the present invention to provide a packaging stopper that can be easily unpacked and used as a dustproof handle during transportation.

3. Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a base body that is fixed by being clamped by a hole member of a packaging box, and a base body that is inserted into a cylindrical part of the base body and presses the hook member. The packaging stopper is composed of a cylindrical key for expanding, and has a closing plate that closes the opening of the cylindrical part of the key and is pushed open by inserting a hand, In addition to functioning as a stopper, the wrapping stopper also functions as a handle, and the hole through which the hand is inserted is usually closed, making it effective in preventing dust.

DESCRIPTION OF THE 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 includes a cylindrical part and this cylindrical part 7.
The cylindrical portion 7 is made up of a flange 8 provided at one end edge and a pair of hook members 10° 1o each having a rounded cross section and connected to the opposing inner wall of the cylindrical portion 7 via a hinge portion 9, respectively. A locking part 11 protruding inward of the opening at one end of the mouth edge on the front side of the opening.
have. The key unit 6 includes a cylindrical portion 12 that fits into the cylindrical portion 7 of the base body 5, and a closing plate 13 that is partially connected to one end of the cylindrical portion 12 and closes a hole in the cylindrical portion 12. It is connected to the base body 5 at the end opposite to the locking part 11 by a connecting piece 14 . A locking protrusion 15 is provided on the outside of the end of the key unit 6 opposite to the connecting piece 14.
, and a protruding piece 16 is provided. Each of these constituent members is made of flexible and bendable polypropylene.

As shown in FIG. 6, the wrapping stopper with the above structure has a hole 1 in which the upper box plate 17 and the lower box plate 18 communicate with each other.
9. Insert the cylindrical part 7 of the base body 6 into 20. 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 5 of the key body 6 is connected to the hook member 10 provided inside the base body 5.
10, the hook member 10.10 is attached to the hinge part 9.
The tip piece engages with the mouth edge of 18 at the inner position. The collar portion 8 of the base body 5 and the hook member 10.10 form two plate bodies 17, 18'? : Tighten. Hikoo, the locking protrusion 15 of the key body 6 engages with 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 a state in which the packaging fastener of the above embodiment is used to connect the upper box 21 and the lower box 22. In the state in which the packaging fastener is attached, the closing plate in the key body 6 is 13 closes the hole of the cylindrical part 12 at the inner part of the cylindrical part 12, and prevents dust from entering from the cylindrical part 12. When the wrapping 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 wrapping stopper can be used to close the hole 19 of the plate body 17, 1B. 20 hole edges are protected.

61-- As shown in FIG. 6, the tip of the cylindrical portion 12 of the key unit 6 is provided with a step to reduce the cylindrical diameter in order to engage a portion of the hook member 10.10. It's good to do that. The bent base body 5 and the key body 6 are connected by a connecting piece 14, but they may be independent, and the base body 5 and the key body 6 may have a rectangular shape other than an ellipse. Effects of the Invention As is clear from the above description of the embodiments, the packaging fastener of the present invention can function as a binding tool for packaging boxes and as a handle tool, and can be easily attached and detached. Furthermore, when the hand is inserted, the hole for inserting the hand is blocked by a blocking plate, so dust cannot enter.However, when using it as a handle, the blocking plate is pushed open by hand, so there is no problem, and its value is 0 is the thickest
