Description

  The present invention relates to a packaging material using cardboard.

  When sending a hard thing or a heavy article in an envelope, if those things move in an envelope, there is a possibility of breaking an envelope. On the other hand, when an object placed in the envelope is fragile, the object may be broken by moving in the envelope.

  In order to prevent this, conventionally, these items are wrapped in an air-filled buffer sheet (so-called “Puchi-Puchi Sheet” (registered trademark of Kawakami Sangyo Co., Ltd.)) before being put in an envelope, or such a sheet. The method of using the envelope which lined the inside was used (for example, patent document 1).

Japanese Utility Model Publication No. 05-051743

  Since the air-filled buffer sheet is made of plastic, a problem occurs when it is discarded. In addition, the method of wrapping in advance with an air-filled buffer sheet takes time and is also unstable during transportation because it also moves within the envelope. Even when an envelope lined with an air-filled buffer sheet is used, the contents cannot be reliably held, and the contents move when a slight impact (acceleration) is applied.

  The problem to be solved by the present invention is to provide a packaging material that securely holds a hard object or a fragile object and protects the contents from an impact.

Corrugated cardboard sandwich packaging material according to the present invention made to solve the above problems,
a) A corrugated first plate having a corrugated plate on one side, at least in the center of the first plate, orthogonal or oblique to the corrugated direction of the corrugated plate, and at least a peak of the corrugated plate A first plate provided with a plurality of cutting lines for cutting a portion;
and b) a second plate disposed to face the corrugated surface of the first plate.

  In the corrugated cardboard packing material according to the present invention, the first plate is a two-stage one-stage plate in which the corrugated board side of another one-stage is bonded to the flat plate side of the corrugated board (which is referred to as “one-stage”). It is desirable to use Of course, this “another single stage” may be both stages (a corrugated sheet sandwiched between two flat sheets). Alternatively, three or more cardboards may be stacked. In any case, the surface facing the second plate has the above-described structure.

  In the corrugated cardboard packing material according to the present invention, a material paper that is softer than the material paper used for normal cardboard may be used for the corrugated sheet on the surface of the first board facing the second board.

  In the cardboard sandwich packaging material according to the present invention, the second plate having the same structure as that of the first plate can be used with the corrugated surfaces of both plates facing each other.

  Although the 1st board and the 2nd board may be isolate | separated, it is good also as what folded one board in the center by making the corrugated sheet side inside.

  A self-adhesive may be applied to at least one of the opposing surfaces of the first plate and the second plate. In this case, it is economical to apply to the ridge line of the first corrugated plate.

  In the corrugated cardboard packing material according to the present invention, when the object to be held is placed in the center portion where the cutting line of the first plate is provided, and the second plate is placed thereon, the first plate and the second plate are strongly pressed, The corrugated plate at the center of the first plate is crushed by the object to be held (pressed and the crest is lowered or falls sideways), but the corrugated plate is crushed because it has a plurality of cutting lines. Is only the part where the object to be held is in contact, and the surrounding part remains the same. Therefore, when the first plate and the second plate are fixed in such a state that the object to be held is sandwiched between them, the object to be held is surrounded by the cutting line and the wave of the corrugated plate along the outer shape, and the first plate It is held between the second plates. In order to obtain the effect of holding in this way with certainty, it is desirable to cut the cutting line deeply close to the corrugated valley. Since it is difficult to bond a corrugated sheet with a cutting line in advance to a flat plate to produce a single step, the cutting line is usually inserted after the corrugated plate is bonded to the flat plate to complete the single step. At this time, the plate is cut as deeply as possible without cutting the flat plate.

  By providing two or three or more stages, the cushioning performance is improved, and the second and subsequent cardboards are also slightly deformed, so that even a slightly larger object can be held.

  By using a material paper that is softer than the material paper used for normal corrugated cardboard for the corrugated plate that faces the second plate of the first plate, the soft object to be held can be held without being damaged.

  Using the same structure as the first plate for the second plate, and using the corrugated surfaces of both plates facing each other makes it possible to hold the object to be held more reliably and to hold it thicker. You can also hold things.

  By folding one plate into the first plate and the second plate with the corrugated plate side inward, the cardboard sandwich packaging material according to the present invention can be handled easily.

  By applying a self-adhesive to at least one of the opposing surfaces of the first and second plates, the object to be held is sandwiched between them, and after closing both plates, both plates are fixed by simply pressing both plates. Is done. In addition to fixing the first plate and the second plate, in addition to the method using the pressure-sensitive adhesive / adhesive, the first plate and the second plate are bound with a pressure-sensitive adhesive tape or a rubber band, or are put in an envelope having the same size as both plates. The method can be used.

The perspective view of the state before use of the corrugated cardboard packing material which is one Example of this invention. The expansion perspective view of the surface of the 1st board of the corrugated cardboard packing material of an Example. The perspective view of the state which put the to-be-held thing on the 1st board of the corrugated cardboard packing material of an Example. The perspective view of the state which opened the both board | substrate after pinching the to-be-held thing between the both board | plates of the corrugated cardboard packing material of an Example.

  The structure and usage of the corrugated cardboard packing material according to an embodiment of the present invention will be described.

  As shown in FIG. 1, the corrugated cardboard packaging material 10 of the present embodiment is obtained by folding a sheet of two corrugated cardboards 11 at the center. Both sides of the fold line 12 become the first plate 13 and the second plate 14.

  As shown in FIG. 2, the two-stage cardboard 11 used in the cardboard sandwich packaging material 10 of the present embodiment is a laminate of two single-stages. A large number of cutting lines 17 are provided in a direction perpendicular to the corrugation 16 of the corrugated plate 15 on the corrugated plate 15 on the surface of the corrugated cardboard 11 (the surface that becomes the opposing surface when folded). Although it is convenient in the processing process to make the cutting lines 17 equally spaced, depending on the shape of the object to be held and the expected size, a form in which a part is rough and a part is fine also brings about a good effect.

  It is desirable to provide the cutting line 17 deeply up to the bottom of the corrugated plate 15. When using the two-stage corrugated cardboard 11 as in the present embodiment, a slight cut may be made up to the one-stage flat plate on the front surface side or to the one-stage corrugated board on the back side, When the buffer performance is important, it is desirable to keep it on the corrugated plate 15 on the front side.

  In this embodiment, the cutting line is perpendicular to the wave line, but it may be slightly inclined. If it is within about plus or minus 30 degrees, the effect almost the same as the vertical case can be obtained. Depending on the shape of the object to be held, it may be easier to hold when such an angle is provided.

  In this embodiment, the cutting line is provided on the entire surface of the two-stage cardboard 11 which is a material, but this is easier to process than providing only a part (center portion).

  The double corrugated cardboard 11 may be formed using material paper used in ordinary cardboard, but it is preferable that the corrugated sheet 15 on the front side is made of softer material paper than the material paper used in ordinary cardboard.

  The corrugated cardboard packing material 10 of this embodiment is used as follows. As shown in FIG. 3, the object 20 is placed on the first plate 13 with the first plate 13 and the second plate 14 opened. And the 1st board 13 and the 2nd board 14 are closed, and both board 13 and 14 is pressed down strongly. As a result, as shown in FIG. 4, the crest of the area (pressing area) 21 in contact with the object to be held 20 of the corrugated sheets 15 on the surfaces of both plates 13 and 14 is crushed, while the surrounding area (non-pressing) The mountain of the corrugated plate 15 in the area 22 is not crushed.

In addition, this invention is not limited to an above-described Example. For example, a self-adhesive material may be applied to at least one of the corrugated plates on the surface side of the first plate and the second plate. In this case, it is economical to apply to the ridge line of the corrugated plate on the surface side of the first plate.
In the above embodiment, one two-stage cardboard is folded at the center and both sides of the fold line are the first plate and the second plate. A single sheet may be formed by connecting with an adhesive tape or the like.
Further, three or more cardboards may be used for the first plate and the second plate.
