Description

The present invention relates to a bag body that can be used as a storage bag for enclosing and carrying documents, an envelope for direct mail that encloses and mails a leaflet for advertising, a medicine bag for containing medicine, and the like.
More specifically, the present invention relates to a bag body in which one bag body is provided with two or more bag portions, so that the types of inclusions can be sorted and stored.

Conventionally, an envelope is a single bag, and even if the user tries to sort and store the stored items such as documents and medicines, they are scattered and confused inside, and they are sorted again when they are taken out. Trouble such as fixing occurs. Therefore, the user had to take some measures to prevent the sorted inclusions from being confused by using multiple envelopes. Under such circumstances, for example, a bag body such as a medicine bag described in JP-A-10-85308 and JP-A-2004-090991 has been proposed.

Japanese Unexamined Patent Publication No. 10-85308 Japanese Unexamined Patent Publication No. 2004-090991

By partitioning the inside of the bag body in any of the above patent documents, the medicines to be stored can be sorted and stored according to the type and usage method. By the way, the medicine bag of Patent Document 1 has a structure in which the edges of leaf pieces made of separate bodies are bonded together. Further, the medicine bag of Patent Document 2 is a bag body in which leaf pieces connected in the lateral direction via a folding portion are folded and the side pieces and the bottom are bonded to each other.

Each of the bags in each of the patent documents is composed of the edges of leaf pieces bonded together. For example, when the stored items are bulky or heavy, an accident may occur in which the stored items break the bonded edges and pop out. Occur. Even if it is not bulky and not heavy, for example, when the stored item is thin and has a plate shape with a sharp edge, it bites into the adhesive layer between the leaf pieces to be bonded and damages or bites into that part. When taking out the stored items, an accident such as breakage from the biting part occurs.

The present invention is a bag body made in consideration of the above problems, and is not a bag body formed by laminating the opposite edges of leaf pieces, but by folding one sheet vertically and horizontally, all except the sealing port. It is a bag body composed of folded parts when leaf pieces with continuous edges are folded. As a result, even if the stored item is bulky and heavy, or even if the stored item has a sharp edge, there is no problem such as breaking and tearing from the edge portion, and in addition, it has two or more sealing portions. It is an object of the present invention to provide a folding bag body that can easily sort stored items and prevent confusion inside the bag body.

In order to solve the above problems, the folding bag body of the present invention includes a unit sheet in which two or more leaf pieces having different or substantially the same widths connected via a vertical fold line are connected in the horizontal direction, and the unit. A unit sheet having substantially the same or different vertical width from the sheet is a folding bag body in which a folding bag body sheet connected vertically and horizontally via a horizontal folding line is folded vertically and horizontally, and the folding bag body sheet is vertically oriented. Fold it in a roll-fold shape along the fold line, fold it in half so that the unit sheets face each other from the horizontal fold line, and bond any part of the opposite leaf pieces so that they cannot be peeled off. It is characterized by having an enclosed portion partitioned into.

As the material used for the folding bag body sheet of the present invention, known paper materials such as high-quality paper, matte paper, and coated paper, as well as synthetic paper, resin film sheet, non-woven fabric, and the like can be preferably used.

Further, various known adhesives can be used as an adhesive for adhering arbitrary portions of the facing surfaces generated by folding the folding bag body sheet of the present invention, and in particular, a completely adhesive film sheet for print lamination. Can be preferably used. After covering the surface of the printed matter to be completely bonded, it is folded so that it faces each other, and when pressure or heating / pressure treatment is applied, the facing film sheets adhere to each other so that they cannot be peeled off. It is convenient because it is easy.

Further, when the folding bag body sheet of the present invention is folded vertically and horizontally, there are a folding sewing machine, a folding streak, and the like as folding means formed in the folding line portion. There is no particular limit to the ratio of cut and uncut of the folding machine. Further, if a folding sewing machine is applied only to the folding bag body sheet and the completely adhesive film sheet is coated on the folding sewing machine, it is possible to simultaneously fold and reinforce against breakage. Further, the folding streaks may be formed, and the folding line portion where no folding means is formed may be forcibly folded by the folding machine without forming the folding means.

The structure of the folding bag sheet of the present invention comprises one narrow leaf piece connected in the horizontal direction via a vertical folding line and two or more leaf pieces having substantially the same width connected to the one leaf piece. The narrow leaf piece may be expanded to substantially the same width as the other leaf pieces. Then, the unit sheets composed of the three or more leaf pieces are connected via the horizontal fold lines of the top and bottom.

Regarding the width of each leaf piece of the unit sheet, for example, in the case of three leaf pieces, in the left leaf piece, the central leaf piece, and the right leaf piece, the relationship is that right leaf piece ≒ central leaf piece ≧ left leaf piece or left leaf piece ≒ central leaf piece ≧ right leaf piece. Then, the leaf pieces on both sides of the central leaf piece are folded in a rolled state so that either the narrow left or right leaf piece is exposed on the uppermost surface. Finally, the unit sheets are folded in half on the narrow leaf piece side so that the unit sheets face each other from the horizontal fold line, but when the leaf piece is folded in half, it becomes the inner surface side and any part of the facing leaf pieces is non-peelablely adhered. A bag portion is formed in the rolled-folded portion. Since the bag portion is formed in the rolled-fold portion of each unit sheet, at least two bag portions are formed and can be used. Further, as will be described later, the relationship between the widths of the three leaf pieces may be right leaf piece ≒ central leaf piece ≒ left leaf piece.

The number of leaf pieces constituting the unit sheet may be three or more, and in that case, each leaf piece is folded in a rolled state, and for example, the exposed narrow leaf pieces are folded from the horizontal fold line so as to face each other. The bag portion generated in this way increases as the number of leaf pieces increases, such as 4 bag parts for 4 leaf pieces and 6 bag parts for 5 leaf pieces.

Further, by manipulating the height of each unit sheet connected vertically, a step is created in the sealing port due to folding from the horizontal fold line, which makes it easier to put in and take out stored items. Furthermore, if the leaf pieces located on the outer side are intentionally cut and the edge on the take-out side is cut off, it will be more convenient to put in and take out the stored items.

Further, the protruding portion may be folded back as a flap for sealing by folding the unit sheet having a wide vertical width along the horizontal fold line. At that time, it is convenient to form a folding sewing machine so that it can be easily folded. Further, when the heights of all the leaf pieces of the flap are the same, all the leaf pieces of the sealing port portion may be folded and sealed.

The folding bag body of the present invention is formed by laminating the open edges of independent leaf pieces, or by laminating the left open edges of the laterally connected leaf pieces. It is not a method of sealing the open edge by an adhesive means, but it is formed by folding lines of all continuous leaf pieces by folding vertically and horizontally. Therefore, accidents caused by using an adhesive such as peeling from the adhesive portion at the edge are eliminated.
In particular, in the form in which the fold line is covered with a completely adhesive film sheet, the fold line portion is reinforced to be more tough against breakage such as tearing.
In addition, the stored items will not be soiled or damaged due to the protrusion of the adhesive or the like.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
In this embodiment, ordinary matte paper (110 kg in terms of 46 plates) is used as the folding bag body sheet S. Further, the completely adhesive film sheet K is a thermal in which a known heat-sensitive adhesive layer is formed on one surface of a base material made of, for example, polyethylene terephthalate or biaxially stretched polypropylene, and a heat treatment layer is formed on the remaining other surface. The one corresponding to the laminating method is used. This product is non-peelable adhered to the surface of the printed matter via the heat-sensitive adhesive layer, and then folded and pressed or heated / pressed so that the heat-treated layers face each other so that the facing surfaces adhere to each other in a non-peelable manner. To do.

Further, in the drawings shown in each embodiment, the postage display circles on the postcards and envelopes appearing on the front surface of the folding bag sheet are drawn to distinguish the front and back surfaces of the folding bag sheet. It goes without saying that the folding bag body of the present invention is not necessarily used as a mailing body (square envelope, etc.), and is applied to a medicine bag or various other bags.

[Folding bag body F1]
The folding bag body F1 shown in FIGS. 1 to 5 is the most basic of the folding bag body of the present invention. The configuration of this product will be described according to the manufacturing sequence shown in FIGS. 6 to 9.

As shown in FIG. 6, the folding bag body sheet S1 for manufacturing the folding bag body F1 of the present invention has the first leaf piece 1 and the second leaf piece 2 connected in the horizontal direction via the vertical folding lines 7 and 8. The fourth leaf piece 4, the fifth leaf piece 5, and the two leaf pieces in which the unit sheet t1 composed of the third leaf piece 3 having a width narrower than that of the two leaf pieces is similarly connected in the horizontal direction via the vertical fold lines 7 and 8. The unit sheet t2 composed of the sixth leaf piece 6 having a narrower width, the first leaf piece 1 and the fourth leaf piece 4, the second leaf piece 2, the fifth leaf piece 5, and the third leaf piece 3 and the third leaf piece 3 through the lateral fold line 9. It is connected vertically so that the six leaf pieces 6 are in contact with each other. Since the unit sheet t1 composed of the first leaf piece 1, the second leaf piece 2, and the third leaf piece 3 has a flap portion at the upper part via the fold line 10, the vertical width is wider than the unit sheet t2 at the lower part. Is getting wider.

The folding bag sheet S1 may be printed on long continuous paper used for form printing or rotary printing, or printed on sheet-fed cut paper used for offset printing or on-demand printing. It doesn't matter if you have it. This printing mode is the same in the following examples.

Then, as shown in FIGS. 7A and 7B, the third leaf piece 3 and the sixth leaf piece 6 of the folding bag body sheet S1 are continuously covered with the completely adhesive film sheet K by various laminating devices, and it is necessary. If there is, a folding means consisting of a folding sewing machine is formed on each folding line. In this embodiment, a folding sewing machine is formed in advance on the vertical folding lines 7 and 8 and the horizontal folding line 9.

The time for forming the folding sewing machine is not limited, and it may be formed in advance and then coated with the completely adhesive film sheet K as in the present embodiment, or may be formed after coating the completely adhesive film sheet. Further, instead of the folding sewing machine, other folding means such as a folding streak may be used, and further, it may be forcibly folded by a folding machine without forming anything. The formation of the folding means for each folding line is the same in each of the following examples.

Next, as shown in FIGS. 8 (A) and 8 (B) and FIGS. 9 (A) and 9 (B), the first leaf piece 1 and the fourth leaf piece 4 of the above-mentioned folding bag body sheet S1 are folded in the vertical direction. Fold from 7 to the back surface side, and further fold the third leaf piece 3 and the sixth leaf piece 6 from the vertical fold line 8 to the back surface side. Further, from the state of FIG. 8B, along the horizontal fold line 9, fold the third leaf piece 3 and the sixth leaf piece 6 in half so that the completely adhesive film sheets K exposed on the back surface side face each other. When the film is folded and subjected to finish pressurization or heating / pressurizing treatment in the state shown in the cross-sectional view in FIG. 3, the completely adhesive film sheets K facing each other are adhered to each other in a non-peelable manner to complete the folding bag body F1. ..

In the folding process, a continuous paper on which the folding bag body sheet S1 is printed or a cut paper in a continuous state due to the coating of the completely adhesive film sheet K is continuously folded from the vertical fold line, and then a single folding bag is used. It may be cut out into the body sheet S1 and folded from the horizontal fold line, or it may be cut out into a single bag body sheet S1 after covering the completely adhesive film sheet K and then folded by a folding machine. There are no particular restrictions on the folding process, the formation time of the folding means, or the like, and after the folding of the single folding bag sheet S1 is finally completed, pressurization or heating / pressurizing treatment is performed to integrate the folding bag sheet S1. The same applies to the various processing steps in the following examples.

The folding bag body F1 thus produced has two storage portions as shown by halftone dots in FIGS. 2 and 3. Then, according to the purpose of use, both sealing ports can be sealed by folding the flap portion protruding from the folding line 10 if necessary. The flap portion may be omitted, in which case the encapsulation port has the same height and does not form a step. The presence or absence of the flap portion is the same in each of the following examples.

As shown in FIG. 3, the overlapping portions of the fourth leaf piece 4, the sixth leaf piece 6, the first leaf piece 1, and the third leaf piece 3 are in a free state without being adhered. Further, the facing surfaces of the fourth leaf piece 4 and the first leaf piece 1 are also in a free state. Therefore, for example, as shown in FIGS. 10 (A) and 10 (B) [see FIGS. 9 (A) and 9 (B)], the completely adhesive film sheet K is interposed between the fourth leaf piece 4 and the first leaf piece 1 to be free. The leaf pieces in the state can be fixed.

Regarding the overlapping portion of each leaf piece when folded in the rolled state, in Example 1, the third leaf piece 3 is folded so as to wrap the first leaf piece 1 as shown in FIG. 9 (A). As shown in 11 (A), the first leaf piece 1 may be folded so as to wrap the third leaf piece 3. At that time, the width of the first leaf piece is made narrower than that of the second leaf piece 2 so that the third leaf piece 3 is exposed from the overlapping portion, and further, a completely adhesive film is applied to the facing surface of the overlapping portion of the first leaf piece 1. If the sheet K is covered, the completed folding bag body F1 becomes an independent space with the storage portion sealed as shown in FIG. 11B, and is exposed from the overlapping portion of the third leaf piece 3. The two storage portions are integrated with each other by the completely adhesive film sheets K of the portions.

Further, in addition to the above-mentioned modification, for example, as shown in FIG. 12A, the overlapping portion of the fourth leaf piece 4 and the sixth leaf piece 6 and the third leaf piece 3 and the first leaf piece 1 may be made inseparable. In the case of a modified example, as shown in FIG. 3B, the facing surfaces of the fourth leaf piece 4 and the first leaf piece 1 may be adhered to each other in a non-peelable manner.

As a further different modification, as shown in FIG. 13 (A), the width of each leaf piece may be substantially the same, and the entire surfaces of the sixth leaf piece 6 and the third leaf piece 3 may be completely adhered. As shown in B), the entire surfaces of the fourth leaf piece 4, the sixth leaf piece 6, the third leaf piece 3, and the first leaf piece 1 may be completely adhered to each other.

The folding bag body F1 having such a configuration can be used not only as an envelope used for mailing but also as a bag body for storing various documents, and it is extremely convenient because it can sort and store small items such as medicines. The same applies to the various folding bags introduced in the following examples with respect to these storage targets and convenience.

[Folding bag body F2]
The folding bag body F2 shown in FIGS. 14A, 14B, 15 and 16 is an increase in the number of leaf pieces in the folding bag body F1 of Example 1. The structure of this product will be described according to the manufacturing sequence shown in FIGS. 17 to 19.

As shown in FIG. 17, the folding bag body sheet S2 for manufacturing the folding bag body F2 of the present invention is the first leaf piece 21, the second leaf piece 21, which is connected in the horizontal direction via the vertical folding lines 29, 30 and 31. The fifth leaf piece 25, the sixth leaf piece 26, and the sixth leaf piece 26, in which the unit sheet t11 composed of the leaf piece 22, the third leaf piece 23, and the fourth leaf piece 24 is similarly connected in the horizontal direction via the vertical folding lines 29, 30, and 31. The unit sheet t12 composed of the seven leaf pieces 27 and the eighth leaf piece 28, the first leaf piece 21 and the fifth leaf piece 25, the second leaf piece 22 and the sixth leaf piece 26, and the third leaf piece 23 and the third leaf piece 23 via the lateral fold line 32. The seven leaf pieces 27 and the fourth leaf piece 24 and the eighth leaf piece 28 are vertically connected so as to be in contact with each other. Since the unit sheet t11 has a flap portion via the upper folding line 33, the vertical width is wider than that of the lower unit sheet 12 by that amount.

Then, as shown in FIG. 17A, the fourth leaf piece 24 and the eighth leaf piece 28 of the folding bag body sheet S2 are covered with a completely adhesive film sheet K, and a folding means made of a folding sewing machine is formed on each folding line. ing.

Next, as shown in FIGS. 18 (A) and 18 (B) and FIGS. 19 (A) and 19 (B), the first leaf piece 21 and the fifth leaf piece 25 of the above-mentioned folding bag body sheet S2 are folded in the vertical direction. Fold from 29 to the back side, and fold each leaf piece from the fold lines 30 and 31 so as to wrap the two leaf pieces. Then, from the state shown in FIG. 18B, along the lateral fold line 32, fold the fourth leaf piece 24 and the eighth leaf 28 in half so that the completely adhesive film sheets K exposed on the back surface side face each other. When the film sheets K are folded and subjected to finish pressurization or heating / pressurizing treatment in the state shown in the cross-sectional view in FIG. 16, the completely adhesive film sheets K facing each other adhere to each other in a non-peelable manner to complete the folding bag body F2. is there.

The folding bag body F2 thus produced has four storage portions as shown by halftone dots in FIGS. 15 and 16. Then, according to the purpose of use, both sealing ports can be sealed by folding the flap portion protruding from the folding line 33, if necessary.

As shown in FIG. 16, the overlapping portions of the sixth leaf piece 26, the eighth leaf piece 28, the fourth leaf piece 24, and the second leaf piece 22 are in a free state without being adhered. Further, the space between the facing surfaces of the sixth leaf piece 26 and the second leaf piece 22 is also free. Regarding this portion, when the leaf piece is folded into the rolled state, the other leaf pieces are folded so as to wrap the first leaf piece 21 as shown in FIG. 19 (A) in Example 2. For example, in FIG. 20 (A). As shown, the fourth leaf piece 24 may be inserted below the first leaf piece 21. At that time, the width of the first leaf piece 21 and the second leaf piece 22 is narrower than that of the third leaf piece 23 so that the fourth leaf piece 24 is exposed from the overlapping portion, and further, the overlapping portion of the first leaf piece 21 If the facing surface is covered with the completely adhesive film sheet K, the completed folding bag body F2 becomes an independent space with the storage portion sealed as shown in FIG. 20 (B), and the fourth leaf piece 24 is described. The four storage portions are integrated with each other by the completely adhesive film sheet K of the portion exposed from the overlapping portion and the exposed portion of the eighth leaf piece 28. Other modifications of the free state are the same as in the first embodiment.

The present invention is not limited to the above examples.
For example, in Example 1, a folding bag sheet S1 in which three upper and lower leaf pieces are connected is used, and in Example 2, a folding bag sheet S2 in which four upper and lower leaf pieces are connected is used, but more leaf pieces are vertically connected. It may be made of a folded bag body sheet.
Further, as shown in FIG. 21, a hook such as a notch may be provided at the edge of inserting and removing the leaf piece inclusions that appear after the folding bag body is finished, so that the opening can be easily opened with a finger. ..
