Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging box device suitable for storing and carrying articles such as portable small electronic devices such as cassette tape recorders.

Packaging boxes of various structures have been used in the past, but the most common packaging box has a structure as shown in FIG.

The packaging box shown in FIG. 1 has two upper flaps 11 (
After storing the article in the main body 10, the retaining tongue piece 12 provided at the tip of the outer upper flap 11 is bent and inserted into the insertion hole 14 formed on the upper surface of the side plate 13. This will seal the storage opening.

However, when a purchaser takes such a packaging box 10 home from a store, he or she hangs a string 15.16 wound several times as shown in the figure, and attaches a separately prepared handle 17 to this string 15.16. It has to be attached to the device so that it can be carried around, which not only requires time and effort in the packaging process, but also makes it difficult to carry it because the handle 17 is not stable when carrying it.Additionally, the material cost is considerable and the packaging device itself is difficult to carry. It had drawbacks such as being expensive.

Also, without using the strings 15 and 16 and the handle 17 as described above,
There are packaging boxes that are designed to maintain a sealed state by engaging a plurality of top flaps in the shape of the packaging box body, or the top flaps themselves form a handle. Packaging boxes have some drawbacks, such as handles that are difficult to grip, complicated assembly and opening when storing or removing items, and considerable consideration must be given to the mechanical strength of the parts that make up the handles.

The present invention has been developed in view of the above-mentioned points, and includes a pair of first top flaps and a pair of second top flaps provided opposite to each other at the upper ends of each of the four side panels of the packaging box body. , each tongue piece formed on both sides of the tip of the pair of second top flaps is inserted and locked with the base part of the pair of second top flaps being bent. and insertion holes provided in the above pair of first top flaps, and the packaging box body is stored at the seam thereof with the pair of first top flaps folded and covered. A pair of bent pieces are provided so as to be close to the upright handle, and a pair of bent pieces are formed by inserting two cut grooves facing each other in the center of the pair of first upper flaps. A cushion is placed between the product and the packaging box body to hold the product and its handle so that it does not move, and the handle of the product is held in an upright or collapsed state as necessary. When carrying such a packaging box device, the article is held so that the handle faces upward with both ends sandwiched between cushions provided at the corners of the main body. After being stored in the main body, the pair of bent pieces are sealed by the pair of first upper flaps and the pair of second upper flaps, and the pair of bent pieces formed by inserting two grooves facing each other are attached to the base part. The product is bent inward to form an opening, and the upright handle of the stored article is exposed on the inner opening surface of this opening, and the handle of the article itself is gripped by this opening. To provide a packaging box device that is easy to work with, has a handle portion that is easy to carry, has sufficient mechanical strength, and can also be made at a much lower cost than conventional packaging containers.

Hereinafter, embodiments of the packaging box device according to the present invention will be described in detail with reference to FIGS. 2 to 6.

In this embodiment, a packaging box device for housing a portable cassette tape recorder will be described.

First, as shown in FIG. 2, a pair of first top flaps 25.26 and a pair of second A top flap 27,28 is provided.

The pair of first upper flaps 25, 26 have two cut grooves 32, 33 and 34 facing each other in the central part of the seam when the pair of first upper flaps 25, 26 are bent at right angles and closed.
．． A pair of bent pieces 36, 37 formed by inserting 35 are provided.

Next, tongue pieces 42.43 and 44.45 are formed by notch grooves 38.39 and 40.41 on both sides of the tip of each of the pair of second upper flaps 27.28, and both flaps 27.29 There is a presser piece 46.4 in the center of the tip.
7 is formed.

Further, the pair of first upper flaps 25.26 have root portions 50.28 of the pair of second upper flaps 27.28.
With 51 bent, each of the above tongue pieces 42 and 43
Insertion holes 52.53 and 54.55 are formed into which the screws and screws 45 are inserted and locked.

In addition, near the root portions 50.51 of the pair of second upper flaps 27.28, there are folded lines 56 so as to facilitate insertion of the tongue pieces 42.43 and the tongues 45 into the holes 52.53 and 54.55. .57 is attached.

Furthermore, the base portions 58 and 59 of the bending pieces 36 and 37 may have perforations or the like to facilitate bending, if necessary.

The cassette tape recorder 30 is placed inside the packaging box main body 20 configured as described above with the top flap 25°26.27.
28 is opened and stored.

In this normal storage state, as shown in FIG.
The tape recorder 30 and its handle 31 are stored in such a way that they are not moved.

After storing the cassette tape recorder 30 in this way,
As shown in FIG. 3, first, with the pair of first upper flaps 25.26 folded and covered, the tongue pieces 42.43 and 44.45 of the pair of second upper flaps 27.28 are folded and closed.
are inserted into the insertion holes 52.53 and 54.55 and sealed.

In this case, the bending pieces 36, 37 are not bent. In addition,
Although the packaging box main body 20 sealed in this manner may be relatively weak against external forces at the center of the upper surface, there is a gap between the upper part of the cassette tape recorder 30 and the pair of first upper flaps 25 and 26. Since there is a sufficient distance between the boxes, even if the upper surface of the packaging box body 20 is subjected to gravity or impact due to stacking during transportation or loading, the burden will not be applied to the cassette tape recorder 30.

Next, when the purchaser carries it from a store, etc., he first opens the top flaps 25, 26, 27, and 28.

Then, the cushions 61 and 63 are removed, and the handle 31 is made to stand up.

The cushions 61, 63 are fitted again, and both ends of the handle 31 are held between the cushions 61, 63 so that the handle 31 does not fall down, and the upper flaps 25, 26 and 27, 28 are used to seal the handle 31 again.

Therefore, as shown in FIGS. 5 and 6, the seam of the pair of sealed first upper flaps 25 and 26 is formed along the longitudinal direction above the upright handle 31 of the cassette tape recorder 30, Further, the bent pieces 36 and 37 are bent from the base portions 58 and 59 and folded inwardly to form an opening 70.

Here, the bent pieces 3 of the pair of first upper flaps 25 and 26 are
The tip portion except for 6° 37 is in almost contact with the upper surface of the handle 31, and the center portion of the handle 31 is exposed on the inner opening surface of the opening.

Therefore, when the tongue pieces 42, 43 and 44° 45 are inserted into the insertion holes 52.53 and 54.55, the pair of first upper flaps 25.26 are locked onto the upper surface of the handle 31 and do not bend too much inward. It is easy to insert, and even when gripping the handle 31, the handle 31 is exposed on the opening surface in an upright position and is in an easy-to-grip position, so the handle can be easily grasped by simply inserting a finger.

Furthermore, when carrying, the handle 31 is held by the cushions 61 and 63 and remains stable without rotating in an upright position, making it easier to carry without the wrist being rubbed by the top flap around the opening, and also allowing you to carry it easily without having to suspend it once. Even when carrying the device again, the handle 31 can be gripped immediately.

In addition, since the handle 31 of the cassette tape recorder 30 itself is held when carried, the cassette tape recorder 30
There is almost no load on the packaging box body 20, and the mechanical strength of engagement with the pair of first top flaps 25, 26 and the pair of second top flaps 27. The surface contact on the upper surface, the tongue pieces 42, 43 and 44, 45, and the presser pieces 46 and 47 provide sufficient strength to maintain the sealed state.

Note that 71.72 and 73.74 are lower flaps, which are assembled in a crossed manner so as not to fall out as usual.

Further, in the above embodiment, the pair of first upper flaps 25.
26 and the pair of second upper flaps 27 and 28, the bent pieces 36 and 37 were bent to form the opening 70. In reality, the latter is easier to work with.

Further, in the above embodiments, a cassette tape recorder is used as an example of the article, but the present invention is not limited to this.

As explained above, according to the packaging box device according to the present invention,
Packaging is easy and the handle can usually be stored with the handle folded down, preventing unnecessary external forces from reaching the item.Furthermore, the handle is held in an upright position when carried, and the inner opening of the opening Since it is exposed on the surface and can be grasped by simply inserting a finger, the handle is easy to grasp and portable, and the packaging box device itself not only has sufficient mechanical strength but also can be made at low cost. This has practical effects.
