Description

[Detailed Description of the Invention] This invention relates to a cushioning material insertion type assembly packaging box that can be used by inserting a cushioning material directly between the product and the box in a packaging box such as a cardboard box that is assembled and used.

On the top and bottom surfaces of this type of cushioning material-inserted assembly packaging box shown in FIGS. Appropriate cushioning materials 4 and 5 are fitted into the notches 3 made in the lid 2, and finally the other pair of outer lids 6 are fitted.
It is folded horizontally to store and protect products such as stereos and televisions, and the packaging is completed with strings, ropes, etc.

However, the cushioning materials 4 and 5 have a certain thickness W due to their nature, and therefore the cushioning materials 4 and 5
When fitted into a predetermined notch 3 made in the inner lid 2,
It protrudes from the inner cover 2 by a corresponding thickness W, and when the outer cover 6 is folded horizontally, a gap with a width W is created between the inner cover 2 and the outer cover 6.

Therefore, in the case of packaging, when passing a rope or the like to a packaging box and attempting to tie it, the packaging box may be placed in a position that is misaligned with the cushioning materials 4 and 5, that is, in a location where there is a gap between the inner lid 2 and the outer lid 6. Since the material of the box is generally cardboard, if the cable is tied too tightly, the outer cover 6 will collapse at the point where the rope or the like is passed, making it impossible to pack it completely. Furthermore, it looks unsightly. Moreover, if this is to be avoided, the packing operation must be carried out while paying careful attention to the place where ropes and the like are passed, which undeniably reduces work efficiency.

This idea was devised by Kurasaku in order to eliminate the above-mentioned drawbacks.

An embodiment of this invention will be described below with reference to FIG. 5 and subsequent figures.

Outer lids 12 are connected to the upper and lower sides of one side wall 11 of the corrugated cardboard assembly packaging box 10 via folding lines a, respectively, and the side wall 1
A folding line c continuous from the folding line a is provided on the upper and lower sides of the side wall 13 which is connected to one side of the folding line B via the folding line b, and an inner lid 14 is provided on the upper and lower sides of the folding line c, respectively, A folding line d is provided parallel to the folding line c at a certain distance above and below the folding line c, and a key-shaped notch is provided in the inner lid 14 outside both ends of the folding line d in contact with the folding line d. 15, and rectangular notches 16 are bored on both sides of the outer end of the inner lid 14. A side wall 17 having the same shape and the same size as the side wall 11 is connected to one side of the side wall 13 via a folding line e, and the upper and lower sides thereof are connected via folding lines f continuous from the folding line c to the outer lid 12. Outer lids 18 of the same size are provided respectively. Furthermore, a side wall 19 of the same shape and size as the side wall 13, which is connected to one side of the side wall 17 via a folding line g, is provided with a folding line h continuous from the folding line f on the upper and lower sides thereof. Inner lids 20 of the same shape and size as the inner lid 14 are arranged on the upper and lower sides of the folding line h, and a folding line i is provided parallel to the folding line h at a fixed distance above and below the folding line h. Key-shaped notches 21 are made in the inner lid 20 on both sides of the curve i, in contact with the folding line i, and rectangular notches 22 are made in both outer ends of the inner lid 20. Also, 23 is the side wall 11
This is a tongue piece that is connected to the other side via a folding line j.

The cardboard assembly packaging box 10 according to this embodiment of the invention consists of four continuous side walls 11, 13, 1.
7 and 19 are bent at respective bending lines b, e, g, and j, and the tongue piece 23 is attached to the outer end side of the side wall 19 to form a quadrilateral outer periphery. Next, move on to forming the bottom surface, by folding the lower inner lids 14 and 20 inward at 180 degrees at the fold lines c and h, and then pulling them up at 90 degrees at the fold lines d and i. Then, the inner lids 14 and 20 are held horizontally, and the edges of the inner lids 14 and 20 are brought into contact with each other. Then, insert the two right-angled surfaces 5'', 5 of the cushioning material 5 shown in FIG. 3, insert one side of the L-shaped cushioning material 4 shown in FIG.
The outer covers 12, 18 are bent inward at 90 degrees at respective folding lines a and f, and stacked on the underside thereof. Therefore, one surface of the cushioning material 4 and one surface 5' of the cushioning material 5 are sandwiched between the inner lids 14, 20 and the outer lids 12, 18. In this packaging box 10, both sides of the lower four corners of the product are in contact with the cushioning materials 5'', 5, the lower surface is in direct contact with the inner lids 14, 20, and the center of the side protrudes from the lower surface of the inner lids 14, 20 of the cushioning material 4. Insert the product so that it hits the inside of the surface.

Next, the inner lids 14, 20, which will form the upper surface, are bent inward by 180 degrees at each of the folding lines c and h, and further pulled up by 90 degrees at each of the folding lines d and i to make the inner lids 14 and 20 horizontal. Then, the notches 15, 21 of the inner lids 14, 20
Insert the two right-angled surfaces 5'', 5 of the cushioning material 5 from above, bring the one surface 5' into close contact with the inner lids 14, 20 from above, and insert the L-shaped cushioning material 4 from above, straddling the notches 16, 22. Insert one side and insert the other side into the inner lid 1
4, 20 and the outer lids 12, 18 are stacked on top of this, and one side of the cushioning material 4 and one side 5' of the cushioning material 5 are connected to the inner lids 14, 20 and the outer lid 12, 18. The outer lids 12 and 1 are sandwiched between the outer lids 12 and 18.
8, and attach the outer lid 1 with rope or packing tape.
2 and 18 are fixed appropriately.

As a result, both sides of the four corners of the upper part of the product are in contact with two right-angled surfaces 5'', 5 of the cushioning material 5, and the top surface is directly connected to the inner lid 1.
4, 20, and the center of the side comes to contact the inside of the surface protruding from the upper surface of the inner lid 14, 20 of the cushioning material 4.

According to this invention, the cushioning materials 4 and 5 are
Notches 15, 16, 21, 2 of inner lid 14, 20 of 0
2 is inserted.

Furthermore, as shown in FIGS. 7 and 8, the cushioning materials 5 located at the four corners have not been in contact with the packaging box, as is clear from a comparison with the conventional example shown in FIGS. 1 and 2. In the present invention, the points (5a in FIG. 2) abut each other between c and d and between h and i of the folding lines of the inner lids 14 and 20, which are connected from the side walls 13 and 19, respectively, so that the cushioning is achieved. The material 5 is now placed in a more fixed position than was previously the case in packaging boxes of this type.

Therefore, since the cushioning material 5 adheres to and supports the product in the above-mentioned stable state, the product is firmly fixed in the packaging box 10, and the packaging box 10
Since it is located inward from the outer periphery by the thickness of one side of the cushioning materials 4 and 5, the product can be protected by preventing impact and pressure applied to the packaging box 10 from being directly transmitted to the product.

Furthermore, as described above, when the outer lids 12 and 18 are folded horizontally, there is no gap due to the thickness of the cushioning materials 4 and 5, unlike in conventional packaging boxes of this type, and ropes, etc. are placed on the top surface of the packaging box 10 during packaging. Even if the outer cover 12, 18 and the side walls 11, 13, 17, 19 are in close contact with each other at the corners as shown in FIG. 12 and 18 will not cave in at the position where the rope is passed. Therefore, it has excellent strength, can be packed tightly, and can be expected to be dustproof. Moreover, the appearance is also nice and clean.

Also, the so-called T-shaped cushioning material 23 shown in FIG.
(Disclosed in Utility Model Application No. 50-43030 (publication of Utility Model Publication No. 57-41184) by the present applicant) as appropriate, a plurality of products can be stored and protected. For example, the first
As shown in Fig. 0, the outer covers 24 and 25 double the outer covers 12 and 18 shown in Fig. 5 vertically and outwardly, and the inner covers 26 and 27 double the inner covers 14 and 20 horizontally and outwardly. Doubled, key-shaped notches 30, 31, 32, 33 are bored at both ends of j, k, respectively, along folding lines j, k on the side walls 28, 29 of the inner lids 26, 27, and further T-shaped notches 34 and 35 are provided along the folding lines j and k, respectively, at the center of the folding lines j and k, while rectangular notches 36 and 35 are provided at both outer ends of the inner lids 26 and 27, respectively.
37, and the above-mentioned notches 30, 31, 32, 33
If the cushioning material 5 is fitted in the notches 36 and 37, the cushioning material 4 is fitted in the notches 34 and 35, and the cushioning material 23 is fitted in the notches 34 and 35, two products can be stored in the previously described embodiments. . In this case, each product can be isolated by the protruding portion 23' of the cushioning material 23 and protected from impact, etc., without using a partition plate or the like.

Even if a conventional packaging box is treated in the same way as this and the same T-shaped cushioning material 23 is fitted and used,
As mentioned above, since there is a gap between the inner lid 2 and the outer lid 6, it goes without saying that the packaging box according to this invention is inferior in stability.

Furthermore, as shown in FIG. 11, outer covers 38 and 39 are provided on the left and right sides, which are twice the size of the outer covers 24 and 25 in the embodiment shown in FIG.
1 makes the inner lids 26 and 27 twice the size vertically,
Along the folding lines l, m on the side walls 42, 43 of the inner lids 40, 41, key-shaped notches 44, 45, 46, 47 are bored at both ends of the folding lines l, m, respectively. T-shaped notches 48 and 4 are provided in the centers of l and m, respectively.
A key-shaped notch 50, 51 is provided at both ends of the outer edges of the inner lids 40, 41, and a T-shaped notch 52 of the same shape and size as the notches 48, 49 is provided at the center of the edge.
53 are bored so as to face the notches 48 and 49, respectively. The packaging box constructed in this way is
When the inner lids 40 and 41 are bent along the respective folding lines l and m and made horizontal and their respective edges abutted, a notch 50,
51 are combined to form a T-shaped notch, and notches 52 and 53 are combined to form a cross-shaped notch, and the T-shaped cushioning material 23 is fitted into these notches and notches 48 and 49, respectively, and used as appropriate. Then, the four products mentioned above can be stored and protected separately from each other without using a partition plate.

In addition, in the developed view of the packaging box according to the embodiment shown in FIG. 5, the same effect can be obtained even if the outer cover 18 is not provided and instead the outer cover 12 is doubled in size and a so-called single-opening outer cover is provided. Needless to say, a great effect can be obtained.
