Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for printing a paper diaper reinforcing sheet in a paper diaper package. 2. Description of the Related Art In recent years, generally used disposable diapers have an absorber interposed between a liquid-impermeable outer sheet and a liquid-permeable top sheet, so that the diaper can be worn by a wearer. For mounting,
Fastening tape for mounting is provided on both sides of the back side of the disposable diaper. It is very difficult to put on a disposable diaper in a satisfactory condition once, and it is actually necessary to refasten it several times. However, the outer sheet is often made of a relatively thin plastic material, for example, a thin sheet of polyethylene, and once the fastening tape is fixed on the outer sheet, it is not possible to peel off the fastening tape without breaking the outer sheet. Because of the difficulty, a reinforcing sheet made of a plastic material is attached to the outer sheet on the ventral side so that the sheet can be fixed and re-attached any number of times. [0003] Although disposable diapers are generally sold individually, 36 or 72 disposable diapers are usually sold as one.
Paying attention to the reinforcing sheet which is sold as a package and affixed to each disposable diaper, the design and illustration printed on each disposable diaper are the same. For infants who use disposable diapers, the design etc. that are drawn are one concern, but if they are all the same design, even if there is a precious design, they will get tired and show no interest. If each diaper to be taken out of the package is given a different drawing, each time you take it out, you will become interested in the design and enjoy the design drawn on each one. Accordingly, a main object of the present invention is to devise a print design of a paper diaper reinforcing sheet. By printing a design mark on the reinforcing sheet, a fancy paper diaper is obtained. The present invention provides a method for printing a disposable diaper reinforcing sheet in a disposable diaper package product which is rich in variety by giving a plurality of different design marks to the diaper. [0005] The invention according to claim 1 of the present invention, which has solved the above-mentioned problems, comprises a fastening tape,

This is a method for printing a reinforcing sheet. According to the present invention, a fancy paper diaper can be obtained by printing a design mark on a reinforcing sheet, and a plurality of different designs can be applied to the reinforcing sheet of each paper diaper in one package to provide a variety of designs. Be rich. Hereinafter, the present invention will be described in detail with reference to examples. As shown in FIG. 4, when the disposable diaper 1 is worn, the disposable diaper 1 is U-shaped and applied to the body of a wearer. 2 is brought to the wearer's abdomen and fastened to the reinforcing sheet 3 stuck on the outer sheet on the abdomen. As the reinforcing sheet 3, paper or a plastic sheet or the like having a release agent applied to its surface can be used, but generally, a plastic sheet is most often used. Taking the most frequently used plastic sheet as an example, a gravure printing method shown in FIG. 3 is generally adopted as a printing method on plastic. Since gravure printing can use a printing ink containing an organic solvent that cannot be used for letterpress and offset printing, it is suitably used for printing on plastic. In addition, flexographic printing, screen printing, etc. can also be adopted. Here, the gravure printing will be briefly described with reference to FIG. 3. A plate cylinder 6 which is partially immersed in gravure ink 8 in an ink container 7 and a pressurizing cylinder which rotates in contact with the plate cylinder 6 A cylinder 5 is provided, and a plastic sheet 3 (a strip state before cutting the reinforcing sheet 3) as a printing material is supplied to the contact portion, and the gravure ink 8 transferred to the surface of the plate cylinder 6 is supplied with a doctor blade 4. Is transferred to the contact portion while being scraped off, and is pressed by the two cylinders 5 and 6 at this contact portion to perform printing on the plastic surface. In the case of multicolor printing, the printing section is provided in series, and a drying section is provided between the printing sections, and multicolor printing is performed by one pass. In gravure printing, a negative is made by copying from a plate-making manuscript of a print, and a transparent positive is made from the negative by an appropriate method. On the other hand, the carbon tissue used as a medium for corroding the plate cylinder is subjected to a photosensitizing process (sensitizing), and gravure screen is printed on the tissue. Then, after the transparent positive is baked on the tissue, it is wound around the plate cylinder 6 to perform transfer. Thereafter, development → coating → corrosion → plate inspection → chrome plating is performed, and printing is performed using the plate cylinder 6 by the method shown in FIG. At the time of printing when obtaining the reinforcing sheet of the present invention, as shown in FIG. 1, the width S of the reinforcing sheet 3 is set in the longitudinal direction of the plate making The pitch is divided into I to VIII as one section. Suppose here that the width S of the reinforcing sheet 3 is 45 mm.
Then, the length L of the plate-making original 9 is 360 mm. I-VI
In each of the divided areas divided by the pitch of II, an unprinted portion of about 10 to 15 mm is provided on each side, and a different design is drawn in each of the divided areas a to h.
The reason why the unprinted portion is provided is to take into consideration the case where the cut line is shifted from the border line of the mutually different designs adjacent to each other, and preferably, the photoelectric tube mark is simultaneously printed on the border line portion of each of the divided areas I to VIII. Then, the cutting position is detected by the photoelectric tube, and the plastic sheet is cut at the predetermined position. FIG. 2 shows a printing method according to the present invention.
As shown in the figure, the number of divisions for dividing the longitudinal length L of the platemaking original 9 by the width S of the reinforcing sheet, that is, L / S =
360/45 = 8 unit design marks A to H are arranged in a dotted pattern. Here, the maximum size of a design mark used S ₀ is not fit to the reinforcing sheet in a width S is too large, also 1/3 of the reinforcement sheet width S in consideration of the arrangement balance between design marks around 2/3.
Further, the arrangement method is such that the design marks A to H are aligned in a longitudinal direction of the plate-making manuscript substantially at a spacing S of the reinforcing sheet width S, and are arranged in a plurality of stages. Are arranged with a shift of 1/3 to 2/3 of the width S of the reinforcing sheet in the longitudinal direction of the plate-making original 9. Thus, no matter where the plastic sheet of FIG. 2 printed according to the present method is cut, it becomes a reinforcing sheet of a different design. By using the reinforcing sheet 3 on which a plurality of types of designs are drawn for a disposable diaper by the above-described method, it becomes possible to enjoy the design for each disposable diaper packed in one package. [0013] In the present invention, as in the above example, a unit design having a size that fits within the predetermined width in a unit area of a predetermined width divided by a pitch in a printing progress direction with respect to a printing target sheet for a reinforcing sheet. Marks are printed in each of the unit areas at the pitch interval, each unit design mark is different in these first unit design mark rows, and further, at a stage separated in a direction orthogonal to the printing progress direction, In each unit area, the combination of the unit design mark in the first unit design mark row and the unit design mark in the second unit design mark row are different, and the target sheet after printing is divided for each pitch. Thereby, the design of the divided reinforcing sheet becomes a plurality of types. Accordingly, the divided reinforcing sheets are attached to the outer sheet of the disposable diaper, and these disposable diapers are packaged in one package, so that the disposable diapers packaged as one package can be provided with variety and taste. Be rich. When the design is used as an index of the fastening position of the fastening tape for the wearer, the difference in the design of the reinforcing sheet in each disposable diaper is rich in variety and taste for the wearer. It gives an impression. As described above in detail, according to the present invention, by printing the design marks on the reinforcing sheet, a fancy paper diaper can be obtained. By applying the design described above, a variety of disposable diaper package products can be obtained.
