Description

Corrugated cardboard free to change shape and pouch using it {CORRUGATED CARDBOARD CAPABLE OF CHANGING SHAPE AND POUCH USING THE SAME}

The present invention relates to a corrugated cardboard with free shape change and a pouch using the same, and more particularly, by forming a bent part in a square and inner diagonal direction on one side of the corrugated cardboard to freely deform the shape of the corrugated cardboard, an article of irregular shape The present invention relates to a corrugated cardboard free to change shape and a pouch using the same, which does not require a separate packaging vinyl and packaging box when packaging items that may be damaged or damaged, and allows the pouch to be used for various purposes.

Pouch is a term that refers to a pouch for carrying various items, but recently, an envelope formed of a paper material is also called a pouch.

Recently, as internet shopping and courier services are active, the use of bag-type pouches is increasing.

According to the pouch in the form of an envelope described above, there is an advantage in that items such as books can be conveniently packed and delivered without a separate packaging box.

However, items that may be damaged during delivery are difficult to transport with the above-described envelope-type pouch.

Accordingly, as shown in Figure 1, after wrapping the article (M) with a packaging plastic (V), it is put in a paper box (B) and wrapped again with a tape (T) and delivered.

As the above-described packaging vinyl (V), a polyethylene material (generally referred to as'poppongi') in which a plurality of circular air layers (air caps) are formed is widely used.

The above-described packaging vinyl (V) is manufactured by laminating a vinyl film having a circular air layer formed thereon and a smooth vinyl film.

In addition, as the material of the paper box (B), a corrugated cardboard obtained by laminating a corrugated corrugated paper between the first and second cardboard is mainly used.

However, according to the packaging method using the above-described packaging vinyl (V) and paper box (B), since both the packaging vinyl (V) and the paper box (B) must be provided, material costs and packaging labor costs are increased.

In addition, after wrapping the product with packaging vinyl (V) and putting it in a paper box (B), the paper box (B) must be closed and wrapped with a tape (T).

Accordingly, there is a disadvantage in that it takes a lot of time to package courier goods that require rapid delivery.

In addition, since too many packaging materials are required for packaging of small items, there is a problem that the waste of resources is severe.

In addition, after delivery is complete, there is a hassle of recycling the packaging vinyl and paper box separately.

In addition, there is a problem that the packaging vinyl used for packaging items that may be damaged is not naturally decomposed, so there is a concern of environmental pollution, and cost is added to recycle it.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<First Example>

2 to 4 show a first embodiment of the present invention.

First, the corrugated cardboard according to the present invention, as shown in Figs. 2 and 3, a first cardboard 11, a second cardboard 12 provided to be spaced apart a predetermined distance from the first cardboard 11, the In the corrugated cardboard comprising a corrugated cardboard 13 provided in a wave shape in the space between the first cardboard 11 and the second cardboard 12, any of the first cardboard 11 or the second cardboard 12 On one side, a square-shaped bent portion 14 is continuously formed in the vertical and horizontal directions.

In addition, each unit square bent portion is formed by crossing the bent portions 14 in a diagonal direction.

Here, the bent part 14 may be formed as a cutout formed by cutting either the first cardboard 11 or the second cardboard 12, as shown in FIG. 2(a). That is, it can be formed by partially cutting the surface of the cardboard with a blade.

In addition, the bent portion 14 may be formed as a perforated hole 14a penetrating through either the first cardboard 11 or the second cardboard 12, as shown in FIG. 2(b).

Further, although not shown in the drawings, the bent portion 14 may be formed as a concave portion formed by deeply pressing either one of the first cardboard 11 or the second cardboard 12.

By the structure of the bent portion 14 described above, as shown in Fig. 3, the corrugated cardboard can be freely deformed.

Also, by adjusting the size of the square, the degree of deformation of the corrugated board can be properly adjusted.

Although it is shown that the corrugated board of FIG. 3 is one, the corrugated board may be manufactured by overlapping two sheets.

When the corrugated board is formed in two, it is preferable that the corrugated cardboard on the outer surface is formed by completely penetrating the incision or through hole, and the corrugated cardboard on the inner surface is simply pressed to form a recess.

With the above structure, even if the thickness of the corrugated board is increased, it is possible to easily deform the corrugated board.

In addition, it is preferable that the inner surface of the cardboard on which the bent portion 14 is not formed is laminated with a simple aluminum foil 40 as shown in FIG. 4.

With the above-described aluminum foil 40, it is possible to obtain an effect of keeping the article cool and warm for a short time.

In addition, in the bag-shaped pouch manufactured using the above-described corrugated cardboard, as shown in FIG. 4, a double-sided tape 20 is attached to the inner surface of the entrance of the pouch 10.

With the above-described double-sided tape 20, it is possible to seal the mouth of the pouch 10 simply and quickly without preparing a separate tape.

Hereinafter, a process of packaging an article using the cardboard according to the present invention will be described.

First, in the corrugated cardboard manufacturing process, a square bent portion 14 having an intersecting diagonal line is continuously formed on one side of the cardboard.

Here, the bent portion 14 may be formed by a cutout portion, a perforation hole, a concave portion, or the like.

In addition, in the case of two-ply corrugated cardboard, the outer surface of the pouch is completely penetrated by forming an incision or perforated hole, and the inner surface is not completely penetrated, but only a concave portion is formed.

Then, when both ends of the corrugated cardboard are connected to each other and the bottom surface is sealed, it becomes an envelope.

Subsequently, when the double-sided tape 20 is attached to the inner surface of the pouch, the pouch is manufactured using corrugated cardboard.

In the case of packing an article in the above-described corrugated pouch 10, first put the article inside the pouch, peel off the peeling tape 22 of the double-sided tape 20, and then use the adhesive side 21 to the inlet of the pouch. Just seal it.

The pouch described above can be usefully used when packaging a flat item having a low height, such as a book.

According to the pouch of the present invention, since the pouch itself is provided with a double-sided tape 20, it is not necessary to prepare a separate tape, and the pouch can be quickly and easily sealed.

In addition, since the pouch made of corrugated board itself absorbs the impact, there is no need to provide a packing vinyl with an air cap when packing items that are likely to be damaged, and put the goods wrapped with packing plastic back into the packing box. There is no need to wrap it.

Accordingly, it is possible to reduce the material cost and labor cost according to the packaging, and because it is possible to quickly package, it is possible to shorten the delivery preparation time.

<Second Example>

5 shows a second embodiment of the present invention.

In the second embodiment of the present invention, the pouch 10 in the form of an envelope manufactured using corrugated cardboard having a bent portion can be transformed into a conventional box shape and used.

Hereinafter, a process of packing a bulky article by transforming a pouch into a paper box will be described with reference to FIG. 5.

First, as shown in Fig. 5(a), a pouch 10 having a bent portion is prepared.

Subsequently, as shown in FIG. 5(b), a bulky article is placed inside the pouch and both sides are bent inward, so that the lower folded portions 31 are formed on both sides of the lower portion of the pouch.

Subsequently, the peeling tape of the double-sided tape 20 attached to the entrance portion is peeled off so that the adhesive surface is exposed.

Subsequently, as shown in FIG. 5(c), when the left folded portion 32 and the right folded portion 33 are folded inward, respectively, and then the rear folded portion 35 and the front folded portion 34 are folded inward, , It is in the form of a conventional packaging box (30).

At this time, the upper portion may be sealed by the adhesive surface of the double-sided tape 20 provided on the inner surface of the entrance portion.

If it is necessary to pack firmly, as shown in Fig. 5(d), it is sufficient to further wrap the tape T around both the upper and lower parts of the box.

According to the second embodiment of the present invention, since the cardboard pouch 10 can be transformed into a conventional packaging box 30 and used, there is no need to prepare a separate packaging box, and loading and transporting of the box is simplified.

In addition, if the aluminum foil 40 is laminated on the inner surface of the box when manufacturing corrugated cardboard, it is possible to insulate and cool the article for about 3 to 5 hours.

Accordingly, bulky items such as fruits, beverages, and frozen meat can be easily transported during various outdoor activities, and delivery food such as lunch boxes can be prevented from cooling during the delivery process.

In addition, the present invention, as shown in Figure 6, it is possible to easily package items of irregular shape with corrugated cardboard, and as shown in Figure 7, as a box for packaging liquor packaging boxes such as wine or items with a large area. It can be easily transformed and used.

When delivering items that may be damaged, they are usually wrapped in plastic packaging with an air cap, then wrapped in a paper box and then transported.

Accordingly, since the packaging vinyl and the paper box must be prepared respectively, the material cost increases and the labor cost according to the packaging increases.

In particular, in the case of an article having a high possibility of damage, there is a problem that the packaging box becomes too large compared to its volume, thereby wasting resources.

In addition, after the delivery of the goods is completed, there is a problem in that the packaging vinyl and the paper box have to be separated and processed, and additional costs are required to recycle the polyethylene vinyl.

In contrast, the present invention does not have to have a separate packaging vinyl by using a corrugated cardboard in a pouch shape.

In addition, since the pouch made of corrugated cardboard can be used by changing the form of a paper box, a separate paper box is not required.

In addition, since the shape of the corrugated board can be freely deformed, it can be very usefully used for packaging items having irregular shapes.

In addition, since a double-sided tape is provided at the entrance of the pouch, it is possible to quickly and conveniently package the article.

In addition, if aluminum foil is laminated on the inner surface of the pouch on one side of the corrugated board and then transformed into a box, it is possible to obtain the effect of warming and cooling the article for 3 to 5 hours.

In the above, a preferred embodiment of the present invention has been exemplarily described, and the scope of the present invention is not limited to the specific embodiment described above. Those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and changes are possible without departing from the scope of the technical idea of the present invention.
