The first core part 101 and the second core part 102 are hermetically sealed by a cover part 200 to be described later to form their own first heat insulating space S1. The non-insertion space A2 is sealed by the first core part 101 and the second core part 102 to form a virtual second heat insulating space S2.

Conventional corrugated paper has a disadvantage that the corrugated core is formed in a waveform along the surface direction of the cardboard, so that the compressive strength in the thickness direction of the cardboard is relatively weak and easily deformed, and because the inner space of the corrugated cardboard is exposed to the outside, moistureproof There was a problem that the function of keeping warm, keeping cold.

On the contrary, in the present invention, since the first core portion 101 and the second core portion 102 are formed perpendicular to the surface direction of the cardboard, the compressive strength can be improved compared to the existing one, and the first heat insulation The air trapped in the space S1 and the second heat insulation space S2 may have an effect of improving the function of the corrugated cardboard while buffering, insulating, damping, and shielding.

In order to shield the open surface of the core 110 in the core part 100, a pair of cover parts 200 are attached to both sides of the core part 100 as shown in FIG. 3.

The cover part 200 may be made of a general paper material, and may be applied to any material having a thin flat plate shape such as a corrugated material or a film.

The cover part 200 is bonded to the non-recessed surfaces of the first core part 101 and the second core part 102 to shield the open core area. That is, as shown in FIG. 2, the airtightness of the first heat insulating space S1 is a structure in which each core 110 configured in the core part is covered and maintained by the cover part 200, and the second heat insulating space S2. As shown in FIG. 4, the airtightness of the first core part 101 and the second core part 102 are bonded to each other and the side surfaces of the second heat insulating space S2 are adjacent to each other. The structure is blocked by six cores 110.

There is a method of improving the airtightness of the 1st core part 101 and the 2nd core part 102 more. Referring to FIG. 5, a recess 101c is recessed in a hexagonal shape in the bottom surface of the insertion space A1 of the first core part 101, and the second core part 102 is inserted into the insertion space A1. When the insertion protrusion 102c protrudes in a hexagonal shape to be inserted into the groove 101c at the end of the core 102a, the end surface of the second core portion 102 and the insertion space A1 of the first core portion 101 are formed. Air gap can be maintained while the gap between the bottom surface is blocked by the insertion protrusion (102c).

As shown in FIG. 3, the shield 300 is inherent in the core 100.

6 is a process diagram showing a process in which the core portion of the corrugated cardboard having the honeycomb structure of FIG. 2 is press-processed, and FIG. 7 is configured in a form in which one unit cardboard made of corrugated cardboard having the honeycomb structure of FIG. It is a side view which showed.

First, as shown in (a) of FIG. 6, the core part 100 is prepared in a flat cardboard state, and the shielding part 300 made of silver foil is double-butted under the old cardboard.

In this state, the hexagonal punches P, which are placed on the presser die M and are arranged in a large number, press the core portion 100.

Then, as shown in (b) of Figure 6, while the core portion 100 and the shielding portion 300 in the flat state of the flat shape is simultaneously press-molded, a plurality of cores 110 having a hexagonal pillar shape is Is made.

If the shielding part 300 is not present, the core part 100 made of a ductile small paper material is frequently torn or punched in the pressing process, and thus the yield of the product may be reduced. However, as shown in the present embodiment, the shield 300 made of a relatively ductile silver foil assists the shape deformation of the core part 100 so that the press molding of the core part 100 can be performed smoothly during the press operation. Function.

Thereafter, as shown in FIG. 6C, the cover part 200 is adhered to the rear surface of the core part 100 to which the shielding part 300 is not attached.

The two core parts 101 and 102, which are integrally coupled to the shield part and the cover part, are disposed to face each other as shown in FIG. 6D, and then the shield part 300 integrally with the core part is disposed. An adhesive (not shown) is applied to each of the recessed ends, and when glued together, one corrugated cardboard having a honeycomb structure is made.

As described above, the present embodiment can be carried out by a three-step process, such as pressing the cover portion → adhere the core portion to the core portion → adhere the pair of core portions to each other.

However, the corrugated paper according to the present embodiment has a limitation in setting the height of the core part 100 because the paper is vulnerable to the press work.

Therefore, the pressing depth of the punch P is preferably set between 1 mm and 5 mm in consideration of the ductility of the original paper. If the pressing depth is less than 1mm, the core 110 of the core portion 100 is insignificant, and the honeycomb structure does not appear properly. If the pressing depth is deeper than 5mm, the original paper is torn while the ductility limit of the original paper is exceeded. This happens because.

As in the present embodiment, the core part 100, the pair of cover parts 200, and the shielding part 300 form a unit board 10 (see FIG. 1) having a thickness of less than 1 cm through a pressing process. do.

As necessary, as shown in FIG. 7, a plurality of unit boards 10 may be configured, and a cardboard having a thickness of 1 cm or more may be provided to consumers by a method of surface-adhering each other in a stacked form via an adhesive layer 11. You may.

On the other hand, the corrugated cardboard according to the present invention has the secondary effect of easy separation and collection. This is explained.

Referring to FIG. 3, the two core portions 101 and 102 and a pair of shielding portions 300 integrally coupled thereto are interdigitated in a zigzag form in the process of being press-molded by a press. to be.

As the two core parts 101 and 102 are bonded together, the pair of shielding parts 300 are bonded to each other, and the shielding part 300 is embedded between the two core parts 101 and 102. do.

Therefore, when the core part 100 is opened by force, the core part 100 and the cover part 200 made of paper can be easily separated from the shielding part 300 made of silver foil.

In addition, the coupling between the core portion and the shielding portion is a physical bonding structure without using an adhesive or the like, which may cause unwanted separation between the core portion and the shielding portion due to external force during use. The adhesive can be integrated between the core and the shield before the formation of the hexagonal column, without applying the adhesive to all areas between the core and the shield to achieve the effect of separate collection as described above. It is also possible to configure it so that it can be easily separated at a later collection time by applying only a part of the contact surface, such as a repetitive line form, regular / irregular dot form, or other lattice form.

Corrugated paper having a honeycomb structure of the present invention configured as described above, the core portion is formed perpendicular to the surface of the cardboard, it is possible to obtain the effect that the compressive strength can be improved compared to the existing, air trapped in the insulation space of the core portion The function of the corrugated cardboard can be improved while buffering, insulating, damping and shielding.

Through this, the present invention, when used in a paper box, it is possible to obtain the effect of removing or replacing the use of a vinyl containing a styropol or buffer for a separate buffer.

In addition, the present invention has the effect that the moisture-proof and shielding function is improved by incorporating a silver foil shielding part in the core part, and adopts a manufacturing method of double-pressing the original paper and the shielding part, thereby making it quick and simple. It is possible to obtain an effect that can produce a corrugated cardboard having a honeycomb structure.

In particular, the present invention has the advantage that can be easily separated and separated by separating the paper and the silver foil by being interlocked with each other in a zigzag form in the process of pressing the core portion and the shield portion by pressing.

The scope of the present invention is not limited to the above-described embodiments and modifications, but may be embodied in various forms of embodiments within the scope of the appended claims. Without departing from the gist of the invention claimed in the claims, it is intended that any person skilled in the art to which the present invention pertains falls within the scope of the claims described herein to various extents which can be modified.
