Description

The present invention relates to a bag that can be used as a storage bag for enclosing and carrying a document, a direct mail envelope for enclosing and mailing a leaflet for advertisement, or a medicine bag containing medicine.
More specifically, the present invention relates to a bag body that can be sorted and stored according to the type of the inclusion because the inside is divided into a plurality of layers.

Conventionally, an envelope is a single bag, and even if a user sorts and stores items such as documents and medicines, they are randomly scattered inside and confused. The trouble of re-sorting occurs. Therefore, the user had to take some measures to pre-sort the enclosure and not to confuse it with others. Under such circumstances, a bag body such as a medicine bag described in JP-A-10-85308 and JP-A-2004-90991 has been proposed.

JP, 10-85308, A JP 2004-90991 A

By partitioning the inside of the bag body in any of the above-mentioned patent documents, it is possible to store the medicines to be stored separately according to the type and the usage method. By the way, the medicine bag of the said patent document 1 is the structure which bonded the edge of the leaf piece which consists of another body. Further, the medicine bag of Patent Document 2 is a bag body in which leaf pieces connected in a lateral direction through a folding portion are folded, and side pieces and a bottom side are attached to each other.

The bags of each of the above patent documents are each configured by laminating the edges of the leaf pieces. For example, when the stored items are bulky or heavy, there is an accident that the stored items pop out by breaking the attached edges. appear. Even if it is not bulky or heavy, for example, when the stored item is a thin plate with a sharp edge, it cuts into the adhesive layer between the leaf pieces that are stuck and damages that part, When taking out an object, an accident such as breakage from the biting part occurs.

The present invention is a bag body made in consideration of the above problems, not a bag body formed by laminating opposing edges of leaf pieces, but by folding a single sheet vertically and horizontally, all except the sealing port. It is a bag constituted by a folded portion when a leaf piece having continuous edges is folded. As a result, even if the object is bulky and heavy, or if it has a sharp edge, it does not cause any trouble such as breaking and tearing from the edge portion, and in addition, it has a plurality of enclosed parts. It is an object of the present invention to provide a folding bag body that can easily sort stored items and can prevent confusion inside the bag body.

In order to solve the above problems, the folding bag according to the present invention has a unit sheet in which three leaf pieces having substantially the same or different lateral widths are connected to each other via a fold line in the vertical direction, and the unit sheet has the same or different vertical width. A unit sheet in which three leaf pieces are connected through the vertical folding line is a folding bag body formed by vertically and horizontally folding a plurality of folding bag sheets that are vertically arranged through the horizontal folding line, Fold a plurality of leaf pieces connected vertically through a horizontal fold line into a winding fold along a vertical fold line, and further fold each unit sheet from the horizontal fold line to confront an arbitrary leaf piece. It is characterized in that it has an enclosing portion divided into a plurality of parts by adhering non-removable portions at arbitrary positions.

As a material used for the folding bag 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, a perfect adhesive film sheet for print laminating can be preferably used as an adhesive agent for adhering arbitrary portions of the facing surfaces caused by folding of the folding bag body sheet of the present invention. In this product, when the surface of the printed matter to be completely adhered is covered and then folded so as to face each other and subjected to pressure or heat/pressure treatment, the opposing film sheets adhere to each other in a non-separable manner.

Further, when the folding bag sheet of the present invention is folded in the vertical and horizontal directions, there are a folding sewing machine, a folding line, etc. as a folding means formed at the folding line portion. There is no particular limitation on the ratio of cut and uncut of the folding sewing machine. If only the folding bag sheet is provided with a folding sewing machine and the complete adhesive film sheet is covered on the folding sewing machine, it is possible to simultaneously fold the sheet and reinforce it against breakage. Further, a folding line may be formed, or a folding line portion where no folding means is formed may be forcibly folded by a folding machine without further forming a folding means.

In the structure of the folding bag sheet according to the present invention, the leaf pieces connected in the horizontal direction through the folding lines in the vertical direction are three leaf pieces. Then, the unit sheets composed of the three leaf pieces are connected in the vertical direction through the fold lines in the horizontal direction of the top and bottom, but the number of connections is not limited.

Regarding the lateral width of the three leaf pieces (left leaf piece, central leaf piece, right leaf piece) of the unit sheet, there is a relationship of central leaf piece>left and right leaf piece and left leaf piece+right leaf piece>central leaf piece. That is, when the left and right leaf pieces are folded from the folding line, the edges of both leaf pieces must overlap. By overlapping, it forms one partition and the internal space of the bag is divided. Further, if the overlapping portion is made to be as wide as the lateral width of the central leaf piece, the left and right leaf pieces serve as partitions, and the inner space is divided into three by a total of two partitions.

When only one side of the folded bag body sheet is covered with the completely adhesive film sheet, the edges of the left and right leaf pieces overlap each other by folding to form one partition, but the overlapped portion remains unbonded. There is no practical problem as it is, but if both sides of either the left or right leaf are covered with the complete adhesive film sheet, the complete adhesive films facing each other at the overlapping part will be a complete partition. ..

Further, by operating the heights of the unit sheets that are vertically connected to each other, a step is created at the sealing port by folding from the folding line in the horizontal direction, which makes it easier to take in and out the stored items. Furthermore, if the leaf piece located on the outermost side is intentionally cut, and the edge on the take-out side is cut off, it becomes easier to take in and out the stored items.

Further, the protruding portion of the leaf piece having the largest vertical width may be folded back to form a flap for sealing. At that time, it is convenient if a folding sewing machine is formed so as to facilitate folding. Further, the flap may be formed by folding all the leaf pieces on the side of the inlet.

The folding bag body of the present invention is not a method of sticking the edges of independent leaf pieces, or a method of sealing the edges that are connected in the lateral direction by folding the edges, that is, a method of sealing each edge by an adhesive means, and by vertical and horizontal folding. All are formed by folding fold lines of continuous leaf pieces. Therefore, accidents caused by using the adhesive such as peeling from the adhesive at the edge are eliminated.
In particular, in the form in which the fold line is covered with the completely adhesive film sheet, the fold line portion is reinforced and is more reinforced against damage such as tearing.
Further, the stored items will not be contaminated or damaged by the protrusion of the adhesive or the like.

The lateral width of each leaf piece is such that the central leaf piece of the three leaf pieces connected in the lateral direction is the widest and the two leaf pieces on both outer sides have overlapping portions when folded. The relationship of the vertical width is the relationship of the first unit sheet>the fourth unit sheet>the second unit sheet≈the third unit sheet.

As shown in FIG. 35, the first leaf piece 81, the fourth leaf piece 84, the seventh leaf piece 87 and the tenth leaf piece 90 of the folding bag sheet S5, the third leaf piece 83, the sixth leaf piece 86, the ninth leaf piece 89 and The complete adhesive film sheet K is coated on the entire surface of the twelfth leaf piece 92 and on the strip-shaped portions along the folding lines 93 and 94 on the surfaces of the second leaf piece 82, the fifth leaf piece 85, the eighth leaf piece 88 and the eleventh leaf piece 91. A folding unit including a folding sewing machine is formed on each folding line. As shown in FIG. 36, almost the entire back surface of the third leaf piece 83, the sixth leaf piece 86, the ninth leaf piece 89 and the twelfth leaf piece 92 is also covered with the complete adhesive film sheet K.

Next, as shown in FIGS. 37 and 38(A), (B), (C), and (D), the first leaf piece 81, the fourth leaf piece 84, and the seventh leaf piece 87 of the folding bag sheet S5 described above. And the tenth leaf piece 90 from the vertical folding line 93 to the back side, and then the third leaf piece 83, the sixth leaf piece 86, the ninth leaf piece 89, and the twelfth leaf piece 92 from the vertical folding line 94 to the back side. Fold in. Then, along the central folding line 96, the completely adhesive film sheets K exposed on the back side of the second leaf piece 82, the fifth leaf piece 85, the eighth leaf piece 88, and the eleventh leaf piece 91 face each other. Then, it is folded in two and finished in the state shown in FIGS. 39(A), (B) and (C).

Subsequently, after cutting and removing the edge of the lateral folding line 96 portion along the alternate long and two short dashes line XX of the fifth leaf piece 85 shown in FIG. 39(A), the lateral folding line 95 to the eleventh portion The leaf piece 91 (the back surface side of the second leaf piece 82) and the eighth leaf piece 88 (the back surface side of the fifth leaf piece 85) are folded in two so as to face each other. Then, the cross-sectional view of FIG. 32 and the perspective view of FIG. 33 are obtained, and when pressure or heat/pressure treatment is performed in that state, the completely adhesive film sheets K facing each other are non-separably bonded and folded. The bag body F5 is completed. The folding bag body F5 made in this way has five storage parts as shown by the halftone dots in FIG.

[Folding bag F6]
By the way, in the above, the exposed surfaces of the eleventh leaf piece 91 and the eighth leaf piece 88 face each other from the state of FIG. 40(A) and (B) (the lower portion along the folding line 96 of the fifth leaf piece 85 is cut off). As described above, the folding lines 95 and 97 in the lateral direction are folded in two as shown by solid arrows, and the state shown in FIGS. 41(A) and 41(B) is finished.
