SOLUTION: This is a corrugated paperboard envelope 1 formed by folding a corrugated paper having a closing margin 2 for sealing and a bonding margin 3 formed thereon and bonding the bonding margin 3 thereto. That envelope 1
A fold line 12 along the width direction is formed on the bottom side, and a fold line 13 along the vertical direction is formed on both end sides,
A plurality of folding lines 13 along the vertical direction are formed at both ends.

Description

[Detailed description of the invention]       [0001]     [Technical field to which the invention belongs]   This invention relates to an envelope made of corrugated cardboard.       [0002]     [Prior art]   BACKGROUND ART Envelopes made of cardboard are frequently used as envelopes used for letters and the like. Ingredient Physically, the cardboard on which the bonding margin is formed is folded, and the bonding margin is bonded. This is the envelope formed.       [0003]     [Problems to be solved by the invention]   Cardboard has some strength, but depending on the flight, Not a few.       [0004]   In addition, cardboard envelopes have few portions that can be used as recycled paper.       [0005]   This inventor was created in view of the above problems, and is stronger than cardboard. Is an envelope that can be used for flights that require It is intended to provide a paper envelope that can be used.       [0006]     [Means for solving the problem]       [0007]   Corrugated cardboard is an example of a material that has a certain strength and can be recycled any number of times. . However, in the case of envelopes made of corrugated paper, the material itself is hard and has a predetermined thickness. As a result, the space inside the envelope is narrowed, and the amount of contents to be sealed is limited. (Limited to very thin ones).       [0008]   Therefore, if the disadvantages of such corrugated cardboard are improved, the strength of the cardboard is higher than that of cardboard. Paper that can be used for flights that require Envelopes could be provided, so the inventor came up with this idea . That is, the present invention is directed to a corrugated cardboard having a closing margin and a sealing margin for sealing. And a corrugated cardboard envelope formed by folding the adhesive margins. Fold lines along the width direction on the bottom side, and folds along the vertical direction on both end sides. Fold lines are formed, and the fold lines along the vertical direction are It is characterized in that a plurality of each are formed.       [0009]   The fold line is a predetermined processing to make it easy to fold from there. Means the line obtained by applying It refers to a line formed by pressing the mold obtained by pressing the mold.       [0010]   If the folding line is folded into a mountain (projecting outward), A so-called gusset is formed, and the gusset causes the envelope to bulge. For this reason, Thick contents can be sealed. In particular, folding along the vertical direction Since multiple lines are formed at both ends, depending on the thickness of the contents, You can adjust how much the fold line of the fold is adjusted, thereby reducing the gusset swelling. It can be adjusted appropriately.       [0011]   In addition, the corrugated paper on which the bonding margin is formed is folded, and the bonding margin is bonded. The manufacturing process is simple, and the unit price of the cardboard itself is low. Together, the costs are extremely low.       [0012]   In addition, corrugated paper can be recycled any number of times, contributing to effective use of resources. It will be.       [0013]     [Embodiment of the invention]   A specific embodiment of the present invention will be described with reference to the drawings. The following form examples are This is merely an example, and it is obvious that the present invention is not limited to this embodiment. .       [0014]   FIG. 1 shows a state in which the envelope 1 is formed, wherein (a) is the front surface and (b) is the back surface. Figure 2 1 shows an unfolded state of the envelope 1 in FIG. Obtained by cutting into forms. In the figure, 2 is a sealing margin, and 3 is an adhesive margin. In this embodiment, both of the margins 2 and 3 are formed on the surface 10 (there is one of them). A part or the whole may be formed on the back surface 11). In this unfolded state, the surface 10 Bend the back 11 so that it overlaps, then fold both margins 3 and fold it back 1 If they are adhered on top of each other, the envelope 1 shown in FIG. 1 is formed. 4 is a notch When the closing part 2 is closed, the tip tongue part 20 is inserted. .       [0015]   On the front surface 10 and the back surface 11 of the envelope 1, the folding lines described below respectively It is formed by pressing. First, on the bottom side, a fold line along the width direction 12, and a folding line 13 is formed on both ends along the vertical direction. Vertical folding The only three lines 13 are formed on one side. These fold lines 12, 13 In each case, the gusset is formed by folding it into a mountain (projecting it outward). Things. In particular, since a plurality of vertical folding lines 13 are formed, The thickness of the space (S in FIG. 3) in the envelope 1 can be adjusted as appropriate. It can be done. One example is shown in FIG. In addition, folding along the width direction A plurality of the penetration lines 12 may be formed.       [0016]   Also, folding lines 21 and 22 along the width direction are provided at the upper end of the surface 10 and the closing margin 2. Is formed. The fold line 21 is for opening and closing the closing margin 2, The fold line 22 is used to bend the closing margin 2 when the envelope 1 expands to make it easier to close. Things. A folding line 14 is also formed on the upper side of the surface 10 along the width direction. This is to form the upper gusset. Close enough If there is a margin 2, a gusset can be formed by folding the margin 2 The folding line 14 as described above may not be particularly provided.       [0017]   Since the envelope 1 of the present embodiment is an envelope made of corrugated paper, a certain strength is required. It is possible to cope with any flights. On the other hand, the folding line 13 formed on the surface Is appropriately folded to form a gusset, so that the thickness of the space S in the envelope 1 can be freely adjusted. Can be adjusted, so that even if the contents to be sealed are thick, ing. Also, since it can be easily manufactured from one sheet of corrugated paper, The process is very simple and the cost is low. Of course, everything Recycled corrugated paper can be used, and after using the envelope 1 of this embodiment, all Since it can be used as paper, resources can be used effectively.       [0018]     [Effect of the invention]   As described above, according to the present invention, even an envelope made of corrugated cardboard is sufficient. An appropriate amount of contents can be sealed. For this reason, flights that require a certain strength Ideal for use as an envelope, the manufacturing process is simple, and the cost is low. I'm done. In addition, all of them can be reused as recycled paper, and resources can be used effectively. It has become something.
