Description

The present invention relates to a storage / transport box having high compressive strength on all sides.

Boxes used to store and / or transport goods are known. These boxes are generally made of cardboard and have a hinged lid. The lid is usually formed of four flaps, two upper flaps and two lower flaps.

These known storage boxes are usually made up of a single sheet with some fold lines, which are assembled to form the box and be ready for use.

For stackable storage boxes and shipping boxes, it is common to use corrugated cardboard to reinforce them. However, with this corrugated paper, not all sides of the box are effectively reinforced against compression.

Patent Document 1 and Patent Document 2 by the same applicant as the present application disclose an example of a box formed of a single sheet and provided with a hinge lid.

Patent Document 1 discloses a storage / transportation box in which the lid portion includes an inner flap and an outer flap, and the outer flaps can be engaged with each other.

The box disclosed in the document has a bottom formed by four sectors connected to each other. When the box is folded or unfolded, those sectors allow the bottom to be automatically folded or unfolded. However, such a box bottom configuration has not been achieved to provide durability against lateral compression in all directions.

Patent Document 2 discloses a storage / transportation / shipping box including a pair of first flaps whose ends are in contact with each other or overlap each other, and a pair of second flaps that can be engaged with each other. Depending on the application, the first flap or the second flap may be used as the inner flap. That is, when the box is used for storage, the box is closed by using the first flap as an inner flap and coupling the second flaps with each other. When the box is used for shipping, the box is closed by using an engageable second flap as the inner flap and applying an additional closing member, such as adhesive tape, to the first flap. Be done.

Since the bottom of the box is not disclosed in the document, it is considered to be the same as the conventional bottom, and strictly speaking, providing durability against lateral compression is achieved in the part around the bottom. It has not been.

An object of the present invention is a reinforced storage / transportation box in which all surfaces of the box, namely the lid, the bottom and the four side walls, are reinforced and the durability against compression is higher than that of a conventional box. To provide a large storage and shipping box.

The storage and shipping box of the present invention solves the above disadvantages and brings other advantages described below.

The storage / transportation box according to the present invention is formed of a single sheet of corrugated material forming a plurality of parallel passages, and the box is
-A lid that is a top lid that includes two inner flaps and two outer flaps, two of which are engageable with each other.
-The bottom of the bottom and
-Four side walls, the four side walls in which the passage of the corrugated material in the four side walls is vertical or inclined at the position in use of the box.
With
The bottom includes two inner flaps and two outer flaps, two of the flaps on the bottom being engageable with each other.

The inner flap is completely or almost completely covered with the outer flap at the position where the inner flap is used. This means that the thickness of the corrugated material is doubled on substantially the entire surface of the lid and / or the bottom.

The engageable flap is preferably the inner flap of the bottom and / or lid, but may be the outer flap.

In order to engage the inner flaps of the lid portion or the outer flaps with each other, the bending lines separating the lid portion and the side wall portion may be made parallel to each other.

Similarly, in order to engage the inner flaps or the outer flaps of the bottom portion with each other, the bending lines separating the bottom portion and the side wall may be made parallel to each other.

The term "passage" in the present specification and claims means a passage of a corrugated material such as corrugated cardboard or plastic. These passages extend from the lid to the bottom. It is preferable that the passage is orthogonal to the lid and the bottom, but in some cases, the passage extends from the lid to the bottom and forms an inclined angle with respect to the lid and the bottom. You may. Further, since the box is formed of a single sheet, if the passage on the side wall has such an arrangement, the arrangement of the passage on the lid and the bottom is also determined.

Preferably, the flaps on the lid and / or bottom are coupled to each other through at least one groove connected to the edge of the flap, one end of which is open in the edge region, and the like. The ends are closed inside the flap. That is, the flaps are partially combined via the at least one groove of each flap.

In a preferred embodiment, the inner ends of the flaps facing each other and engaging with each other are configured to contact each other in the closed position. This makes it possible to increase the lateral compression and vertical compression of the entire box. Preferably, the at least one groove is parallel to or inclined with respect to the passage of the corrugated material.

Advantageously, in one embodiment of the invention, the outer flaps of the lid and / or bottom are overlapped with each other. In other embodiments, these flaps face each other at the edges of the flaps at the flap closed position.

With this configuration, the box is extremely durable on all surfaces of the box (ie, the lid, the bottom and the side walls) regardless of the orientation in which they are carried.

In addition, the engageable inner flaps increase the durability of the central portion, allowing for a reinforced structure that blocks access to the interior of the box with minimal cardboard consumption.

In addition, by closing the outer flap, the engageable inner flap can be reused without damage.

Another advantage of the box of the present invention is that the engageable inner flap doubles the thickness of the central region, thus improving the durability of the bottom against the weight of the contents.

Since the box is formed of a single sheet, the passage of the corrugated material of the inner flap and the passage of the corrugated material of the outer flap are substantially orthogonal to each other at the lid portion and the bottom portion.

In addition, when the boxes are stacked, the side walls in which the corrugated material passages are arranged vertically or at an angle provide durability against vertical compression. Moreover, the engageable inner flaps greatly hinder lateral compression, and the edge of the inner flap also contacts the inside of the side wall where the outer flap extends, so that the side wall is on the side. It is durable against pressure from the side.

Further, due to the double thickness of the corrugated material at the lid portion and the bottom portion, even if the outer flap is closed with the adhesive tape, the box can be opened without damaging the articles inside the box by using the cut body. Can be opened.

Another advantage of the inner flaps of the lid and bottom being engageable is improper access to the inside of the box before opening the box, unlike traditional boxes where there is a gap between the inner tabs. Is impossible.

Another advantage of the box according to the present invention is that the flaps forming the lid and the bottom do not move inside the box when closed or assembled to the position where the flaps are used. This means that even if the box is full, the box can be closed at the lid or bottom of the box.

In a preferred embodiment, the inner flap of the lid and / or the inner flap of the bottom has at least one coupling groove forming at least two tabs. In addition, one of the tabs is set longer than the other tabs, facilitating coupling. In a preferred embodiment, the bottom and lid engageable flaps incorporate two, three or four engaging grooves to form three, four or five tabs, respectively. , The length of at least one of the tabs is set longer than the remaining tabs, which makes the coupling easier and stronger. The configuration of incorporating two or more coupling grooves is of outstanding length (eg, skis, golf clubs, rackets) because the large number of grooves disperses the locking mechanism along the entire length of the box and increases its strength. , Lighting equipment, curtains, etc.) will be of particular interest in boxes for storing and transporting.

In some embodiments, a long tab extends beyond the middle closure line in the closed form. As a result, the double-layered portion strengthens the coupling lock mechanism and also enhances the compressive strength at the bottom or lid. In an embodiment in which a plurality of grooves and tabs are provided, it is preferable that long tabs and short tabs are sequentially provided alternately along the edge portion. This simplifies the coupling mechanism and at the same time increases its strength (reinforce).

Further, the inner flap of the bottom and / or the lid is connected to the outer flap of the bottom and / or the lid at the connecting portion. For example, the connecting portion has a triangular shape and forms a bending line of the inner flap.

In one preferred embodiment, the triangle formed by each connecting portion is a right-angled isosceles triangle.

In one embodiment, it is preferred that the lid and / or the outer flap of the bottom of the box further comprises a closing member. The closing member is, for example, a double-sided tape and / or an adhesive, or a tab in the outer flap that is introduced into an accommodating portion provided in the inner flap. In one embodiment of the present invention, the closing member formed by the protrusion and the groove or the housing portion is also used as an engaging body of the engageable flap.

In one embodiment of a storage / transport box according to the present invention, the outer flap may include a tear strip which is at least one tearable strip (open body) that facilitates opening of the box. ..

One embodiment of the storage / transport box according to the present invention has two handle openings on two opposite sides for easy handling.

First, the box according to the present invention is formed from a single sheet of corrugated material (preferably corrugated cardboard) forming a plurality of passages substantially parallel to each other.

The boxes of the present invention can be used for storage and / or transportation of goods. That is, the box is required to have strength characteristics so that the article is not damaged when the box is used, which is also stackable.

1 to 6 show a box according to the first embodiment of the present invention.

In the first embodiment, the box is formed of a corrugated cardboard sheet 1 that forms a lid 10, a bottom 11, and four side walls 12, 13 at the assembly position of the box.

The lid portion 10 is formed by two pairs of flaps, an inner flap 2 and an outer flap 3. The inner flap 2 is hingeably extended from the facing side walls 12, and the outer flap 3 is hingedly extended from the facing side walls 13.

The bottom portion 11 is also formed by two pairs of flaps, an inner flap 4 and an outer flap 5. The inner flap 4 is also hingedly extended from the facing side walls 12, and the outer flap 5 is also hingedly extended from the facing side wall 13.

In the illustrated embodiment, the inner flaps 2 of the lid 10 and the inner flaps 4 of the bottom 11 can engage with each other. That is, the inner flaps 2 and 4 have at least one groove 7, and the at least one groove 7 forms at least two tabs 8 and 9 which are overlapped with each other at the assembly position. As can be seen in the drawing, one of tabs 8 and 9 may be longer than the other tabs. This facilitates the coupling and, at the closed position, makes the coupling stronger against compression and at the same time more stable.

However, the flaps that can be engaged as described above may be the outer flaps 3 and 5 of the bottom portion 11 and / or the lid portion 10.

In order to engage the inner flaps of the lid portion 10 or the outer flaps with each other, the bending lines separating the lid portion 10 and the side walls 12 and 13 may be made parallel to each other.

Similarly, in order to engage the inner flaps of the bottom portion 11 or the outer flaps with each other, the bending lines separating the bottom portion 11 and the side walls 12 and 13 may be made parallel to each other.

The inner flap 4 of the bottom portion 11 forms a substantially flat surface at the closed position of the inner flap 4.

In one embodiment, the inner flaps 2 and 4 are not connected to the outer flaps 3 and 5. That is, the inner flaps 2 and 4 in the lid portion 10 and the bottom portion 11 are connected only to the corresponding side wall 12. However, the inner flaps 2 and 4 and the outer flaps 3 and 5 may be connected by the connecting portion 14.

In the illustrated embodiment, the inner flap 4 of the bottom portion 11 is connected to the outer flap 5 by the connecting portion 14. Although not shown, the inner flap 2 of the lid portion 10 may also be connected to the outer flap 3 of the lid portion 10.

The inner flap 4 and the outer flap 5 of the bottom portion 11 may also omit the connecting portion 14 as depicted for the lid portion 10 in the drawing.

The connecting portion 14 is preferably triangular, more preferably a right-angled isosceles triangle.

In one embodiment, the two opposing side walls 13 have a handle opening 15 that facilitates the handling of the box.

In the illustrated embodiment, the direction of the passage of the corrugated material on the side walls 12 and 13 is vertical at the use position of the side walls 12 and 13, but the passage may be inclined at an angle. .. Further, since the box is formed of a single sheet, the corrugated material in the inner flaps 2 and 4 of the lid 10 and the bottom 11 and the corrugated material in the flaps 3 and 5 of the lid 10 and the bottom 11. The strength is increased by being substantially orthogonal to each other.

Next, a method of assembling the box according to the present invention will be described.

First, in the box manufacturing plant, the fastening tab 16 is fastened to the opposite side wall 13. The box in this form is completely flat at the pre-assembly position of the box. Therefore, the space occupied by the box before the article is put in is small and easy to carry.

When the box is used, the box is placed in the position shown in FIG. 2 in which the lid 10 and the bottom 11 of the box are open. Although the closing operation of the bottom portion 11 is drawn first in the drawing, the closing operation of the lid portion 10 and the bottom portion 11 may be performed in any order.

To close the bottom, first, the bendable inner flap 4 is bent toward the inside of the box, as shown in FIG.

In the present embodiment, since the outer flap 5 is connected to the inner flap 4 via the connecting portion 14, when the inner flap 4 is bent, the outer flap 5 is also bent.

When the inner flap 4 is bent, the inner flap 4 is engaged with each other through the groove 7, and the tab 8 and the tab 9 overlap each other. The tabs 8 and 9 are sized so that the flaps 4 can be closed to each other without using an additional closing member.

In the illustrated embodiment, additional closing members such as adhesive tape or staples are applied to the outer flap 5 to close the bottom 11. For this purpose, the outer flaps 5 are placed close to each other at the closed position of the outer flaps 5 so that the opposing ends of the outer flaps 5 are brought close to each other with a slight gap, separated from each other, or as a whole. Or it is partially overlapped. This makes it possible to apply the additional closing member.

The closing operation of the lid portion 10 is also performed in the same manner. First, as described above, the inner flaps 2 are bent and engaged with each other, and then the outer flaps 3 are bent and closed with an additional closing member such as an adhesive tape or staples.

As in the case of the outer flap 5 of the bottom portion 11, is the outer flap 3 of the lid portion 10 also close to each other with a slight gap between the opposite ends of the outer flap 3 at the closed position of the outer flap 3? , Or overlaid in whole or in part. This makes it possible to apply the additional closing member.

As described above, the box according to the present invention is a reinforced box in which the lid portion, the bottom portion and the side wall portion have high strength against an external force toward the inside of the box.

The closure member 17 may be double-sided tape or adhesive, or with any other suitable component (eg, a protrusion in the outer flap that is introduced into the accommodating portion provided in the inner flap). is there.

In this embodiment, the outer flap 3 further comprises a tear strip 6 that facilitates opening. The tear strip 6 may be formed of a band-shaped body in which the flap itself is pre-cut, or may be formed of an additional band-shaped body such as a plastic material.

As can be seen in FIG. 7, the outer flaps 3 of the lid portion 10 in this embodiment are slightly longer than those in the above-described embodiment, and the outer flaps 3 are overlapped with each other. In the present embodiment, they are partially overlapped, but may be completely overlapped.

As can be seen in FIG. 16, the assembly work of the box in this embodiment is common to that described above. The difference is that the closing of the box is performed using the closing member 17, and the opening of the box is performed using the tear strip 6 as can be seen in FIG.

However, although the tear strip 6 is used, the outer flap 3 of the lid 10 can be resealed with an additional closing member such as adhesive tape or staples after opening once.

FIG. 8 shows a further embodiment of the box according to the present invention. This embodiment is very similar to the embodiment of FIG. 7, except that the outer flap 5 of the bottom 11 also has the closing member 17 and the tear strip 6.

The assembling work, closing work and opening work are the same as those in the embodiment of FIG.

FIG. 9 shows a further embodiment of the box according to the present invention. The difference from the first embodiment described above is that a connecting portion 14 having the same function as the connecting portion described above also exists between the inner flap 2 and the outer flap 3 of the lid portion 10.

FIG. 12 shows a further embodiment of the box according to the present invention. The difference from the first embodiment described above is that the connecting portion 14 does not exist at the bottom portion 11, and the inner flap 4 and the outer flap 5 of the bottom portion 11 are the same as the inner flap 2 and the outer flap 3 of the lid portion 10. It is a point that becomes.

FIG. 13 shows a further embodiment of the box according to the present invention. The difference from the embodiment of FIG. 12 is that the closing member 17 and the tear strip 6 are present on the outer flap 3 of the lid portion 10.

FIG. 14 shows a further embodiment of the box according to the present invention. The difference from the embodiment shown in FIG. 13 is that the closing member 17 and the tear strip 6 are also present on the outer flap 5 of the bottom portion 11.

FIG. 15 shows a further embodiment of the box according to the present invention. This embodiment is similar to the embodiment of FIG. 12, but the outer flaps 3 of the lid 10 and the outer flaps 5 of the bottom 11 can also be engaged with each other, that is, the outer flaps 3 and 5 are inside. It differs in that it has at least one groove 7 forming a pair of tabs 8 and 9 like the flaps 2 and 4.

In this case, since the outer flaps 3 and 5 can be closed by themselves due to the dimensions of the tabs 8 and 9, it is not necessary to provide a closing member on the outer flap itself or to use an additional closing member. FIG. 18 shows in detail how the box of the present embodiment is partially closed. In the figure, it can be seen that the inner flap 2 of the lid portion 10 is in the closed position of the inner flap 2 and the outer flap 3 is in the open state.
