BEST MODE FOR CARRYING OUT THE INVENTION
First, as a first embodiment of the present invention, a cardboard box used for carrying leek will be described with reference to FIGS.
[0010]
In the blank shown in FIG. 1, a pair of side walls 1 and end walls 2 are alternately provided continuously, and a passage 3 is continuously provided on an outer edge of one side wall 1. Short side flaps 4 and end flaps 5 are respectively connected to upper edges of the side walls 1 and the end walls 2, and sealing plates 6 and 7 are respectively connected to lower edges of the side walls 1 and the end walls 2.
[0011]
On both sides of the side flap 4, hugging portions 14 protruding from the leading edge are provided, and the side flap 4 is U-shaped. A folded plate 10 is connected to the end of the end flap 5 via a connection between cuts, and retaining pieces 11 are connected to both sides thereof. Cuts 12 and 13 are formed in the sealing plates 6 and 7, respectively.
[0012]
To assemble the blank, as shown in FIG. 2, each pair of the side walls 1 and the end wall 2 is bent into a rectangular cylindrical shape, and the passage 3 is attached to the opposite end wall 2 to form a peripheral wall. The side flaps 4 are bent inward, and the folding plate 10 is pushed between the opposing side flaps 4 while bending the retaining pieces 11 inward or outward.
[0013]
Next, as shown in FIG. 3, when the box is turned upside down and the retaining piece 11 is bent back, the retaining piece 11 prevents the folded plate 10 from coming off from between the opposing side flaps 4 and the side flap 4. And the end flap 5 are engaged, and the lower top surface side is sealed with a gap left in the center.
[0014]
Then, when the leek is inserted into the box in this state, the leek is longer than the gap between the end flaps 5 facing each other, so that the leek is supported by the side flaps 4 and the end flaps 5 without dropping from the gap at the center. The folded plate 10 is held down by the weight, and the side flaps 4 and the end flaps 5 are completely locked.
[0015]
Thereafter, the sealing plates 6 and 7 are closed, and while the sealing plate 7 is bent along the ruled line, the sealing plates 6 and 7 are engaged by inserting the cuts 12 and 13 so that the bottom surface facing upward is removed. After sealing and returning the upside down as shown in FIG. 4, preparation for shipment of the green onion is completed.
[0016]
In the cardboard box sealed in this way, the end of the end flap 5 is reinforced by the folded plate 10 and embraces the holding portion 14 of the side flap 4. Also, the end flap 5 is less likely to be torn.
[0017]
In addition, since the folding plate 10 is prevented from being removed from between the opposing side flaps 4 by the retaining pieces 11, the engagement between the side flaps 4 and the end flaps 5 does not come off, and the seal is released during transportation in the market. Spreading green onions is prevented.
[0018]
Further, the shape of the box is stabilized and the rigidity is improved by bringing the tip of the folded plate 10 into contact with the inner surface of the end wall 2, so that the load of the stored material is applied while the end is gripped during transportation. In addition, the outer shape of the box is hardly deformed, and the side flaps 4 are hardly broken.
[0019]
Next, as a second embodiment of the present invention, a modified example of the first embodiment will be described with reference to FIGS. Here, the description will focus on the differences from the first embodiment.
[0020]
In this cardboard box blank, as shown in FIG. 5, L-shaped cuts 8 are made in the side flaps 4 from the front edges of both sides, and a hugging portion 14 is provided on the outside and a restraining piece 9 is provided on the inside. Is formed.
[0021]
When assembling this blank, as shown in FIG. 6, the retaining pieces 11 are folded over the folded plate 10 and both are inserted into the cuts 8 of the side flaps 4.
[0022]
When the folded plate 10 is inserted in this manner, as shown in FIG. 7, the folded plate 10 is pressed by the restraining piece 9 and falls down to the base end side of the end flap 5, and the retaining piece 11 is restored by rebound. The folded plate 10 is prevented from falling out of the cut 8.
[0023]
In this state, since the rebound of the folded plate 10 is suppressed by the suppression pieces 9, the green onion can be easily stored.
[0024]
Then, when the sealing plates 6 and 7 are closed and engaged, and as shown in FIG.
[0025]
In the cardboard box sealed as described above, similarly to the first embodiment, even if the end flap 5 is transported by putting a finger on the end thereof, the end flap 5 is not easily torn, and the folded plate 10 is cut from the cut 8. Since it is securely prevented from falling off, excellent sealing properties can be obtained.
[0026]
Next, as a third embodiment of the present invention, a cardboard box for transporting general articles will be described with reference to FIGS. 9 to 12, focusing on differences from the above embodiment.
[0027]
As shown in the blank of FIG. 9, this cardboard box has a sealing structure in which a side flap 4 and an end flap 5 are engaged with each other on the bottom surface of the box. A side flap 4 and an end flap 5 having a length capable of completely closing the bottom face are provided, and sealing plates 6 and 7 are respectively provided on the upper edge thereof.
[0028]
In order to assemble the blank, as shown in FIG. 10, the pair of side walls 1 and the end wall 2 are turned upside down and each pair of the side walls 1 and the end wall 2 are bent into a rectangular cylindrical shape, and the joint 3 is attached to the end wall 2 on the opposite side. Is formed, the pair of side flaps 4 are bent inward, and the folded plate 10 is inserted into the cuts 8 of the side flaps 4 together with the retaining pieces 11 that have been folded.
[0029]

[0030]
In this state, the folded plate 10 is pressed by the suppression piece 9 and falls down to the base end side of the end flap 5, and the rebound is suppressed by the suppression piece 9, so that the article can be easily stored in the box, The folded plate 10 is held in the lying state by the weight of the article, and the side flaps 4 and the end flaps 5 are completely locked.
[0031]
After that, as shown in FIG. 12, the sealing plates 6 and 7 are closed, and the sealing plates 6 and 7 are engaged by inserting the cuts 12 and 13 while bending the sealing plate 7 along the ruled lines. It can be sealed without using an adhesive tape or an adhesive, and can be used for transporting various articles.
[0032]
In addition, since the shape of the box is stabilized and the rigidity is improved by bringing the tip of the folded plate 10 into contact with the inner surface of the end wall 2, the outer shape of the box is deformed even if a biased load is applied during transportation. And the side flaps 4 are also less likely to be torn.
[0033]
In addition, the blank of the cardboard box shown in each of the first to third embodiments is creased in a partial pattern after the creases and grooves are cut in the same manner as a normal grooved cardboard box. Therefore, it can be manufactured at a lower cost than the one punched by a mold, and can be supplied at a low cost.
