Description

  The present invention relates to a method for manufacturing handbags and a packaging material for handbags.

Various materials, such as a film, paper, and a nonwoven fabric, are used for handbags.
In order to manufacture handbags made of the various materials described above, a sheet is subjected to gravure printing, offset printing, and flexographic printing, and then a bag is formed and a grip portion is formed. In the case of non-woven fabrics, names may be put in by silk printing after bag making.
Although gravure printing is suitable for mass production, the letters and designs printed on handbags must be the same for bags manufactured on the same line.

Nowadays, it is considered that Small Office Home Office (SOHO) and individuals produce special products in small quantities for celebrations and commemorations. For this reason, only a small amount of handbags having different designs or the like may be required according to the customer's request. In this case, gravure printing or the like cannot meet the customer's request.
It is conceivable to use an ink jet printer or a laser printer for a small amount of printing.
There is a conventional example of manufacturing a resin film bag by printing on a tubular thermoplastic resin film with an ink jet printer and then bag-making (Patent Document 1).

JP 2006-305980 A

In the conventional example of Patent Document 1, an inkjet printer is used for printing. However, since printing is performed after printing on a resin film, it is not necessarily suitable for low-volume production.
In order to produce handbags only in small quantities, a bag body made from a sheet is prepared in advance, and a gripping portion is formed by cutting the bag body in an annular shape. It is possible to print with a printer.

For example, in the case of using an ink jet printer, ink is applied from the discharge section while feeding the bag body one sheet at a time using a feed roller. However, since the two sheets of the bag body are stacked, the friction resistance between the feed roller and the bag body is different in the vicinity of the annular gripping portion compared to the portion adjacent to this portion, and the two sheets are stacked. Sheet misalignment will cause a paper feed error.
Furthermore, some ink jet printers and laser printers are provided with a sensor for detecting the size of the object to be printed. However, the sensor may malfunction due to the annular gripping portion.

  An object of the present invention is to provide a method for manufacturing handbags and a packaging material for handbags, which can easily print a small amount of handbags having different designs.

  The method for producing handbags according to the present invention is a method for manufacturing handbags in which a grip portion is formed on a bag body made from a sheet, the grip portion being notched partially in the bag body. A notch forming step for leaving a part, a printing step that is performed after the notch forming step and printing while feeding the bag body one by one with a feed roller, and is performed after the printing step and the bag body A gripping part completion step of cutting the non-notched part to complete the gripping part.

In the present invention, the handbags are manufactured through a series of steps including a notch forming step, a printing step, and a gripping portion completion step. In the printing process, printing is carried out while feeding the bag body one sheet at a time using a feed roller using an ink jet printer or a laser printer, so that small amounts of handbags with different designs printed on the bag body can be produced.
In the notch formation process, the gripping part is not completely cut out, but is formed by leaving a non-notch part in part. Therefore, in the printing process using the inkjet printer or laser printer in the next process, the bag body When printing while feeding one sheet at a time with a feed roller, the sheet near the grip part is not displaced by the non-notched part, and there is no annular notch in the case where a sensor for detecting the size is provided, No paper feed error occurs.

In the manufacturing method of the handbags of this invention, the said sheet | seat has a preferable structure containing the layer which consists of a nonwoven fabric.
Handbags made from non-woven fabrics are not only low in production cost but also strong and durable. And since the bag body made from the nonwoven fabric can be made thin, it is suitable for printing using an inkjet printer or a laser printer.

In the method for manufacturing the handbags of the present invention, the bag body is formed with a storage opening for storing an object to be stored by extending to one side, and the notch for the gripping part is a linear first cutout. And a C-shaped part having a second notch formed by bending from the end of the first notch to the storage opening, and the notch forming step includes the first notch A configuration in which the C-shaped part is formed while leaving the non-notched part in the part is preferable.
In this configuration, the notch for the gripping part is not formed as an annular part but as a C-shaped part. For this reason, the C-shaped portion has a portion that is not cut out compared to the annular portion, and therefore, when the bag body is fed by the feed roller, the sheet near the notch for the gripping portion constituting the gripping portion is displaced. It can be surely suppressed.
Furthermore, the user can easily use the handbags by separating and bending the notched portion located on the opening side of the C-shaped portion of the bag body to form an annular gripping portion.

In the method for manufacturing the handbags according to the present invention, the notch for the gripping part is disposed at the center in the direction along the one side, and the non-notch part is provided at a central part of the first notch part. A configuration is preferred.
In this configuration, since the center of the bag body is usually fed by the feed roller, the above-described effects can be achieved efficiently.

The packaging material for handbags of the present invention is a packaging material for handbags used to manufacture handbags having a grip portion formed on a bag body made from a sheet containing a nonwoven fabric, and includes a front surface, a back surface, A bag having a printable area on at least one of which is provided with a printable region and a storage opening for storing a storage object extending to one side, and the gripping part is a non-notched part. It is characterized by having a notch for the gripping part that leaves the mark.
In the present invention, since the packaging material for handbags can be directly sent to an ink jet printer or a laser printer, printing can be performed on the printable area of the bag using these printers. In printing by these printers, when printing is performed while feeding the bag body one sheet at a time by a feed roller, the sheet in the vicinity of the gripping portion is not displaced by the non-notched portion, and printing can be performed stably.

[Packaging materials for handbags]
The packaging material for handbags concerning one Embodiment of this invention is demonstrated based on drawing.
FIG. 1 shows a packaging material for handbags according to this embodiment. The packaging material for handbags is used for producing handbags.
In FIG. 1, a packaging material 1 for handbags is provided with a flat rectangular bag 2 made from a non-woven sheet. Here, the non-woven fabric is preferably made of long fibers that can be printed by an ink jet printer and do not cause the fibers to fall off by a spunbond method or a spreading method. The material of the nonwoven fabric is composed of polyester, polyethylene terephthalate, or other materials. The nonwoven fabric has a thickness of 50 g / m ² or more and 120 g / m ² or less.
The bag body 2 is formed by folding the sheet in two and ultrasonically sealing along both sides of the folded portion. A storage opening 2 </ b> A is formed to extend to one side of the bag body 2 at an end edge of the bag body 2 opposite to the portion where the sheet is folded. An object to be stored can be stored or taken out of the bag body 2 from the storage opening 2A.

A printable region 2B that can be printed is formed on both the front surface and the back surface of the bag body 2 (only the front surface is shown in the figure). In the printable area 2B, various designs, characters, and the like are printed using an inkjet printer described later.
Here, the printable area 2 </ b> B is configured by an ink receiving liquid receiving layer (not shown) formed on the surface of the nonwoven fabric when printing is performed using an ink made of a dye or a pigment. In the case where the liquid-receiving layer is provided, the nonwoven fabric may be a flat or uneven fabric.

A grip portion 2C is provided in the center of the bag body 2 between the storage opening 2A and the printable area 2B along the one side where the storage opening 2A is formed.
The grip portion 2 </ b> C includes a grip portion notch 3.
The grip part notch 3 has a linear first notch part 31 and a second notch part 32 formed by bending from both ends of the first notch part 31 toward the storage opening 2A. C-shaped portion 30. In the figure, the first notch 31 and the second notch 32 are each curved, but in the present embodiment, they may be straight and the C-shaped part 30 may be a U-shaped plane.
The C-shaped part 30 is formed through two sheets constituting the bag body 2.
One non-notched portion 33 is left in the center of the first notched portion 31. The non-notch portion 33 is a portion that connects the inside and outside of the C-shaped portion 30 of the first notch portion 31 at all. The widthwise dimension of the non-notched portion 33 (the dimension along the longitudinal direction of the first notched portion 31) is appropriately set based on the size of the bag body 2, the thickness, the strength of the nonwoven fabric, and other conditions. For example, it is 1 mm or more and 10 mm or less.

[Handbag manufacturing method]
Next, the manufacturing method of the handbags concerning one Embodiment of this invention is demonstrated based on FIG.2 and FIG.3.
First, as shown in FIG. 2A, a handbag packaging material 1 is prepared.
One sheet made of a nonwoven fabric is folded in half, and both sides thereof are ultrasonically sealed to manufacture the bag body 2. A heat seal may be used instead of the ultrasonic seal.
[Cut forming process]
Then, using the punching blade, the C-shaped portion 30 is punched into the bag body 2 so as to leave the non-notched portion 33 to form the gripping portion notch 3. Here, in order to leave the non-notched part 33 in the C-shaped part 30 of the grip part notch 3, the punching blade may be a part of the flat C-shaped part or may be divided into left and right. You may use what has the cut blade part.
Thereby, the packaging material 1 for handbags is manufactured.

[Printing process]
As shown in FIG. 2B, printing is performed on the printable area 2B of the bag body 2.
Printing is performed by the inkjet printer 10 of FIG.
In FIG. 3, an inkjet printer 10 includes a case 11, a feed roller 12 that is provided in the case 11 and feeds the packaging material 1 for handbags, a printing unit 13 that is provided so as to be movable forward and backward in the axial direction of the feed roller 12, and a handbag. And a feeder 14 for feeding the packaging material 1 for similar use to the feed roller 12.

The handbag packaging material 1 is set in the feeder 14. At this time, the handbag packaging material 1 is arranged so that the C-shaped portion 30 is on the opposite side of the leading side in the feeding direction of the handbag packaging material 1. As a result, when the C-shaped portion 30 is placed on the handbag packaging material 1, normal printing is performed from the bottom to the top.
The handbag packaging material 1 set in the feeder 14 is fed to the feed roller 12 one by one. The handbag packaging material 1 is printed on the printable area 2 </ b> B by the printing unit 13 while being fed by the feed roller 12. The gripping part notch 3 passes through the feed roller 12, but the C-shaped part 30 constituting the gripping part notch 3 has the non-notch part 33, so that the overlapping part of the sheet is displaced. There is no print.

[Grip part completion process]
As shown in FIG. 2C, the non-notched portion 33 remaining in the bag body 2 is cut by the cutter 4 to complete the grip portion notch 3. Instead of the cutter 4, scissors or the like may be used. As a result, a continuous C-shaped notch 3 for a gripping portion is formed in the packaging material 1 for handbags, and the handbags are completed.

  As shown in FIG. 2D, when using the handbags, the storage opening 2A is opened to store the storage object P inside the bag body 2, and the C-shaped portion 30 is not cut away. The portion is bent to form the grip portion 2C in an annular shape.

Therefore, in this embodiment, the following effects can be achieved.
(1) The grip body notch 3 is partially formed on the bag body 2 while leaving the non-notched portion 33, and then the bag body 2 is inkjet-printed while being fed by the feed roller 12 one by one. The non-notched portion 33 is cut to complete the grip portion 2C. That is, since printing is performed while the bag body 2 is fed one by one by the feed roller 12 using the inkjet printer 10, a small amount of handbags having different designs printed on the bag body 2 can be manufactured. In addition, the notch 3 for the gripping part is not formed by being completely cut out, but is formed by leaving the non-notched part 33 in a part, so that in the printing process using the ink jet printer 10, the bag body 2 is one by one. When printing while being fed by the feed roller 12, the non-notched portion 33 does not cause a sheet near the gripping portion to be displaced, and a paper feed error does not occur.

(2) Since the sheet | seat which comprises the bag body 2 consists of a nonwoven fabric, it not only can suppress manufacturing cost low, but has intensity | strength and durability.
(3) The grip part notch 3 includes a linear first notch part 31 and a second notch part 32 formed by bending from both ends of the first notch part 31 toward the storage opening 2A. The first notch 31 is formed leaving the non-notch 33. Since the C-shaped portion 30 has a portion that is not cut out, when the bag body 2 is fed by the feed roller 12, it is possible to reliably suppress the displacement of the sheet in the vicinity of the grip portion. Furthermore, it is easy to use handbags by bending the part of the C-shaped part 30 of the bag body 2 that is not cut out to form the annular gripping part 2C.

(4) The notch 3 for the gripping portion is disposed at the center in the direction along one side of the bag body 2, and the non-notched portion 33 is provided at the center of the first notch portion 31. 33 passes through the feed roller 12, so that the deviation of the sheet in the vicinity of the gripping portion can be reliably prevented and the occurrence of a paper feed error can be eliminated.

(5) The packaging material 1 for handbags includes a bag body 2 made from a sheet containing a non-woven fabric, and the bag body 2 stores a printable area 2B in which printing is possible and an object P to be stored. 2A and a gripping portion 2C are provided, and the gripping portion 2C has a gripping portion notch 3 in which a non-notch portion 33 is partially left, so that the packaging material 1 for handbags is directly inkjetted. Printing can be performed using a printer.
