Description

[Detailed Description of the Invention] The present invention relates to a packaging container, and more particularly to a packaging container suitable for packaging cooking knives and the like.

Packaging containers for cooking knives, forks, etc.
Conventionally, it was composed of three parts: the main case, the top lid, and the middle frame shaped like a knife or fork, and was designed to increase the commercial value of the knives and forks it accommodates and to enhance the display effect.

However, when such packaging containers are adopted,
For example, when exporting, the space occupied by the packaging container is several times larger than the space occupied by the knife or fork itself, and this has a large impact on freight costs, increasing the price of the product. becomes.
Of course, a packaging container made of three components is expensive to manufacture, and not only does it affect shipping costs, but the packaging container accounts for a large portion of the price of the knife, which further increases the price and weakens competitiveness in the market. That was the result.

The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a low-cost packaging container that has an extremely simple structure, can compactly house knives, etc., is easy to manufacture, and can be manufactured at low cost.

Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

The packaging container 1 according to the present invention is formed by punching out a continuous piece of cardboard, as shown in the expanded view in FIG. That is, this packaging container 1 includes a lower plate 2 formed in a rectangular shape, a side plate 4 that is continuous to the lower plate 2 via a fold line 3 and has a width approximately equal to the thickness of the handle of a knife, and a side plate 4 that is parallel to the fold line 3 on the side plate 4. The upper plate 6 has a top plate 6 having the same size as the lower plate 2 which is continuous through a fold line 5, and a side plate 8 having the same width as the side plate 4 is continuous to the top plate 6 via a fold line 7. A substantially triangular folded piece 10 is continuously formed on the side plate 8 along a fold line 9. As is clear from FIG. 1, the folding piece 10 has a flat isosceles triangular shape, and its base side is continuous with the side plate 8 via the fold line 9.
A protrusion 10a is formed at the top of the folded piece 10, and bulges 10 are formed at the upper and lower ends of the protrusion 10a.
b are formed respectively.

A side plate 12 having the same width as the side plate 4 is continuously formed at the upper end of the lower plate 2 through a fold line 11 formed across the lower plate 2. The bent pieces 14 are continuously formed through the bending pieces 14. A plurality of notches 15 to 1 of different sizes are formed in the widthwise center of the bent piece 14.
7 is formed. These cuts 15 to 17 are formed in a U-shape that opens outward, and by forming these cuts 15 to 17, quadrilateral tongue pieces 15a to 17a are formed. Further, the upper and lower ends of these cuts 15 to 17 are connected by fold lines 18, except for the tongue pieces 15a to 17a. A flat chevron-shaped notch 19 is formed in the lower plate 2 at a position closer to the fold line 3 and approximately at the center in the longitudinal direction, facing in the direction of the fold line 3.

Further, a bent piece 23 is continuously formed at the lower end of the lower plate 2 via a fold line 20 formed across the lower plate 2. The size of this bent piece 23 is approximately 1/2 of the size of the lower plate 2. This bent piece 23 has a notch 24 parallel to the folding line 20 at a position opposite the notch 15, a notch 25 at a position corresponding to the notch 16, and a notch 25 corresponding to the notch 17. A notch 26 is formed at the position. As is clear from FIG. 1, these cuts 24 to 26 are formed with their positions shifted in the longitudinal direction of the bent piece 23. Also, below the notch 25, as is clear from Fig. 1, there is a angular C.
A letter-shaped notch 27 is formed. The open end side of this cut 27 faces the direction of the cut 25,
By forming this cut 27, a quadrilateral tongue piece 27a is formed.

On the other hand, a bent piece 29 is continuously formed at the upper end of the upper plate 6 via a folding line 28 formed across the upper end. The size of this bent piece 29 is approximately 1/2 of the size of the upper plate 6. Cuts 30 to 32 parallel to the fold line 28 are formed in the folded piece 29 with positions shifted in the longitudinal direction and the width direction.

Further, a side plate 34 having the same width as the side plate 4 is continuously formed on the lower end side of the upper plate 6 via a fold line 33 formed across the upper plate, and a fold line 35 is formed on this side plate 34. A bent piece 36 having approximately the same size as the bent piece 14 is continuously formed therebetween. This bent piece 36 has the above-mentioned cuts 30 to 3.
U-shaped notches 37 to 39 that open outward are formed at positions corresponding to 2, and by forming these notches 37 to 39, quadrilateral tongue pieces 37a to 39a are respectively formed. There is. Then, with the upper and lower ends of the U-shaped cuts 37 to 39 tied together, a fold line 40 is formed in a state where the tongue pieces 37a to 39a are avoided, respectively.

Next, a method of using the packaging container 1 constructed as above will be explained.

First, as shown in FIG. 2, a valley fold is made at right angles from the fold line 11 formed on the upper end of the lower plate 2, and then a valley fold is made at right angles from the fold line 13 so as to be parallel to the lower plate 2, and then a valley fold is made at right angles from the fold line 13. A valley fold is performed from the side fold line 18 in an inclined state toward the lower plate 2, and a mountain fold is performed from the outer fold line 18 so that the tip of the folded piece 14 is parallel to and overlaps the lower plate 2. Then, the tongues 15a to 17a defined by forming the cuts 15 to 17 are placed over the lower plate 2 as shown in FIG.

Then, a valley fold is performed from the fold line 20 at the lower end of the lower plate 2 to overlap the folded piece 23 on the lower plate 2.

Then, a valley fold is performed from the fold line 28 at the upper end of the upper plate 6, and the folded piece 29 is stacked on the upper plate 6. and,
A valley fold is made perpendicularly from a folding line 33 at the lower end of the upper plate 6 to stand up a side plate 34 at a right angle, and a valley fold is further made at a right angle from a folding line 35 to bend a folding piece 36 parallel to the upper plate 6. Then, a fold line 40 on the side closer to the fold line 35
From there, perform a valley fold toward the upper plate 6 side, and then perform a mountain fold from the outer fold line 40 so that the tip of the bent piece 36 becomes parallel to the upper plate 6, and then It is stacked on the upper plate 6 as shown in FIGS. 3 and 4. In this state, as is clear from FIG. 4, the tongue piece 37a defined by the notches 37 to 39
.about.39a are in a state of being overlaid on the upper plate 6. A perspective view of the folded state is shown in FIG.

Next, as shown in FIG. 6, a small knife (for example, a butter knife) 41 and a fork 4
2 and a large knife 43. That is, after inserting the tip of the blade 41a of the knife 41 into the notch 24 of the bent piece 23, the handle 41b is fitted into the space formed by the notch 15. In this case, the handle 41b is fitted while pulling the bent piece 14 so that the side plate 12 is inclined outward, and the handle 41b is fitted.
What is necessary is to push the bent piece 14 back to its original position so that the end portion b touches the inner surface of the side plate 12.

To accommodate the fork 42, first cut the tip of the bifurcated blade 42a into a U-shaped notch 27.
Insert the blade 42a so as to sandwich the base of the tongue 27a and push the tongue 27a downward, and guide the tip of the blade 42a upward through the notch 25 again.
The handle 42b side is guided into the space formed by the notch 16 by the same operation as described above.

In addition, in order to accommodate the knife 43, the blade 43a is
is inserted into the notch 26, and then its handle 43b is accommodated in the space formed by the notch 17 in the same manner as described above.

When the knives 41, 43 and fork 42 are accommodated in this way, the blade 41a of the knife 41 and the blade 43a of the knife 43 are guided between the bent piece 23 and the lower plate 2, and the handles 41b, 41b are inserted into the notch 15, 17
Since the base end is in contact with the inner surface of the side plate 12, the side plate 12 and the notches 24, 2
6 prevents the knives 41, 43 from being displaced and are reliably accommodated. Furthermore, the knife's cutting edge is located inside the folded piece 23, so it is safe.

Furthermore, if the notches 15, 17 and the handles 41a, 43b are tightly fitted, the knives 41, 43 can be more reliably prevented from shifting. The same applies to the fork 42.

Next, the knives 44 to 46 are housed on the upper plate 6 side.

Knives 44 to 46 are the knives 41 to 43 described above.
and is housed with its vertical direction reversed. That is, the blade 44a of the knife 44 is inserted into the notch 30 of the bent piece 29, and the handle 44b is fitted into the space formed by the notch 37. In this case, in order to fit the handle 44b, the bent piece 36 is moved toward the front, the side plate 34 is tilted outward, and the handle 44b is fitted into the space formed by the notch 37. After that, return it to the original position, handle 44
The base end of b is brought into contact with the inner surface of the side plate 34.

The blade 45a of the knife 45 is inserted into the notch 31, and the handle 45b is fitted into the space formed by the notch 38 in the same manner as described above.

The blade 46a of the knife 46 is inserted into the notch 32, and the handle 46b is fitted into the space formed by the notch 39 in the same manner as described above.

If the knives 44 to 46 are housed in this way, the movement of each blade edge is regulated by the notches 30 to 32, and each handle is in contact with the inner surface of the side plate 34 on the bending piece 36 side, so that The movement is restricted, and the notches 37 to 39 and handles 44b to 4
If the fit with 4b is tightened, the knife 44-4
6 is not displaced and is held more reliably.

After storing the knives in the lower plate 2 and the upper plate 6 in opposite directions in this way, perform a valley fold from the fold lines 3 and 5, stacking the upper plate 6 side on the lower plate 2,
Further, perform valley folds from fold lines 7 and 9, and fold back piece 10.
Fold the protrusion 10a to the lower side of the lower plate 2, and
When the knife is inserted into the notch 19 of the knife, packaging of the knife is completed.

When the knife packaging is completed in this way, the knives housed in the lower plate 2 and the upper plate 6 are housed with their handles and blade edges facing in opposite directions, so that each knife does not get in the way of the other. It can be stored in a flat state.

When the packaging is completed, the upper and lower sides of the packaging container 1 are closed by the side plates 12 and 34, and the left and right edges are closed by the side plates 4 and 8, and these side plates are closed by the lower plate 2 or 34, respectively. Since it is perpendicular to the upper plate 6, the thickness of the internal handle also works, and even when stacked in multiple stages, it will not collapse due to its weight.

As is clear from the above description, according to the present invention, multiple knives are punched out from a single piece of cardboard and simply folded without gluing or the like, and a plurality of knives can be attached to each side of the upper and lower plates. It is possible to obtain a packaging container that can accommodate. Therefore, the storage density of knives is extremely large, whereas the packaging container itself occupies a very small space and is not heavy, which greatly reduces the shipping cost, which is a component of the product price, even in the case of export. be able to.

In addition, since it is simply folded from cardboard and does not require gluing, it has the advantage of being extremely low cost and inexpensive to manufacture.
