JP 2001-327430 A JP 2013-60306 A JP2013-70815A

  Conventional toilet rolls that are impregnated with deodorant or fragrance on the roll core do not last long for the deodorizing function and fragrance spreading effect, and when the use of the toilet roll ends, its functions and effects are extremely reduced. Further improvement is desired.

  In addition, there are many requests for toilet rolls with additional functions.

  An object of the present invention is to provide a toilet roll and a method for manufacturing the toilet roll that can continuously exhibit a desired function not only at the start of use but also at the end of use.

  A first aspect of the present invention is a toilet roll on which a pattern is printed, wherein the ink used for printing the pattern includes a sanitary medicine.

  Designs intended by the present invention include figures, photographs or photographs of people, animals, plants, vehicles, food, tools, clothes, toys, buildings, natural objects, constellations, characters from myths and old tales, animated characters, etc. , Characters, symbols, figures, patterns and combinations thereof. Furthermore, differences in the background and their hues are also included.

  In the toilet roll according to the present invention, the sanitary agent may include at least one of a deodorant, a fragrance, an antibacterial agent, a disinfectant, and a cleaning agent. More specifically, examples of the deodorant include fine powder of an inorganic porous material as disclosed in Patent Document 2, for example. Examples of fragrances include various essential oils. Examples of the antibacterial agent include natural antibacterial agents such as herbs and eucalyptus in addition to copper zeolite and silver zeolite. Examples of the disinfectant include benzalkonium chloride and paraben. Examples of the detergent include citric acid in addition to surfactants such as cationic surfactants, anionic surfactants, nonionic surfactants, and zwitterionic surfactants. In any case, it is preferable to add to the ink in a preferable diluted state using an appropriate solvent in consideration of accompanying skin contact. In addition, other appropriate sanitary drugs can be used as long as there is no problem in terms of safety to the human body in terms of quantity.

  The ink for printing the design on the toilet roll must be one that does not adversely affect the human body and does not cause chemical changes even when the above-mentioned sanitary chemicals are added. It is desirable. As such an ink, various known inks can be used regardless of whether they are oily or water-based. Preferably, the ink is a water-soluble ink, which contains a pigment, an aqueous varnish (synthetic resin and water), an additive, contains less than 4% ethanol as a solvent, and uses an epoxy-modified polyamide resin as a binder resin. Things can be mentioned. The above-mentioned epoxy-modified polyamide resin reacts with a polyamine component containing a polyalkylene polyamine as an essential component and a dicarboxylic acid component under the conditions in which an amino group is present in excess, and further reacts with an epihalohydrin. It is an epoxy-modified polyamide resin obtained. If printing is performed using such a water-soluble ink, printing can be carried out without impairing the soft texture and suppressing ink back-through and paper shrinkage.

  It is preferable to print a pattern on the surface of the toilet roll having higher smoothness, which has different smoothness on the front and back sides.

  When the toilet roll is formed by laminating a plurality of sheets, it is preferable to print the design on the side of the overlapping surface of at least one sheet.

  The second aspect of the present invention includes a step of preparing a base paper made through a Yankee dryer, and a step of printing a design on the surface of the base paper on the side in contact with the cylinder of the Yankee dryer. The method of manufacturing a toilet roll is characterized in that the ink used in the preparation contains a sanitary medicine.

  According to the toilet roll of the present invention, since the ink used for printing the pattern includes a sanitary medicine, a desired function can be continuously exhibited from the start of use to the end of use. Also, since the design is printed, you can expect to use it happily.

  When the sanitary agent contains an antibacterial agent or disinfectant, the buttocks can be wiped cleanly, and the toilet paper after use can improve the sanitary condition of the toilet bowl to some extent. Moreover, when the chemical | medical agent for hygiene contains a washing | cleaning agent, the washing effect can be given with the toilet paper after use with respect to a toilet bowl.

  When a design is printed on the higher smooth surface of a toilet roll having different smoothness on the front and back, the clarity can be improved even for a complicated design.

  In a toilet roll in which a plurality of sheets are laminated, when a design is printed on the overlapping surface side of at least one sheet, the sanitary medicine can be kept out of direct contact with the user's skin.

  According to the method for producing a toilet roll of the present invention, as a result of the pattern being printed on the surface of the toilet roll having higher smoothness, the clarity of the complex roll can be improved. And the desired function regarding the sanitary chemical | medical agent can be continuously exhibited from the time of use start of a toilet roll to the end of use.

It is a three-dimensional projection figure showing the external appearance of one Example which applied this invention to the toilet roll of 2 sheets together (double type). It is sectional drawing which represents typically the structure of the toilet roll shown in FIG. It is a conceptual diagram which represents typically an example of the manufacturing equipment of the base paper of the toilet roll shown in FIG.

  An embodiment in which the present invention is applied to a two-piece toilet roll (double type) will be described in detail with reference to FIGS. However, the present invention is not limited to such an embodiment, but can be applied to a single type or a three-piece toilet roll.

  The appearance of an embodiment of a toilet roll that is the subject of the present invention is shown in FIG. The toilet roll 10 in this embodiment is obtained by winding a laminated continuous sheet 13 in which a water-decomposable surface tissue 11 and a water-decomposable back surface tissue 12 are overlapped on a cylindrical core 14 for a predetermined length.

  A desired pattern 15 is printed using ink on the overlapping surface 11 a of the front surface tissue 11 and the back surface tissue 12. The overlapping surface 11a of the surface tissue 11 has higher smoothness than the surface on the opposite side, and the pattern 15 can be printed more finely. Usually, when making the base paper of the toilet roll 10, the side that comes into contact with the cylinder of a Yankee dryer described later tends to be smoother than the opposite side. Therefore, it is effective to set the side of the base paper that contacts the cylinder of the Yankee dryer as the overlapping surface 11a of the surface tissue 11 and print the pattern 15 there. The ink for printing the pattern 15 includes a sanitary agent, and the sanitary agent includes at least one of a deodorant, a fragrance, an antibacterial agent, a disinfectant, and a cleaning agent.

  Thus, since the pattern 15 is printed on the overlapping surface 11 a of the surface tissue 11, the pattern 15 can be seen through from the outside through the surface tissue 11, and a soft impression can be given to the surface tissue 11. In addition, there is less possibility that sanitary medicine or ink directly contacts the user's skin, and higher safety can be ensured.

  On the other hand, a large number of truncated cone-shaped embossed portions 16 are formed on the back surface tissue 12 so as to protrude toward the overlapping surface 11 a side of the front surface tissue 11. By projecting such an embossed portion 16 toward the overlapping surface 11 a side of the front surface tissue 11, the surface of the back surface tissue 12 can be kept in good touch. As the pattern of the embossed portion 16 formed on the back surface tissue 12, an arbitrary pattern other than that shown in the figure can be adopted as necessary, but the formation of the embossed portion 16 is not essential in the present invention. . However, it is also possible to form such an embossed portion on the surface tissue 11.

FIG. 3 schematically shows a papermaking facility for the base paper to be the front surface tissue 11 and the back surface tissue 12. That is, the papermaking equipment is equipped with a wire part _{P W,} a press part _{P P,} and a dry part _{P D,} and calendar Part _{P C,} and a reel part _{P R.}

In the wire part P _W, supplied between the outer wire 21a and the end portion of the forming unit 21 in advance paper stock components are prepared from the headbox 20 containing moisture in large amounts of the inner wire 21b to be connected to the press part P _P To do. And the paper layer C used as the prototype of tissue paper is formed between these. A large amount of moisture contained in the paper stock is dehydrated here, and the paper layer C is formed by the inner wire 21b of the forming unit 21, so that the texture of the paper layer C is adjusted.

In the press part P _P, apply pressure to the paper layer C formed at the wire part P _W, moisture contained in the paper layer C is squeezed. Here, the surface of the paper layer C is smoothed, and at the same time, the density of the pulp component constituting the main part of the paper layer C is increased to form a strong paper layer C.

In the dry part P _D, by heating the excess water of the paper layer C in the wet state through the press part P _P by a Yankee dryer 22, forcibly evaporated, thereby drying the paper layer C. Paper layer C was dried wound on the cylinder 23 of the Yankee dryer 22 is peeled off from the surface of the cylinder 23 by a doctor blade 24, is unloaded into the calendar Part P _C.

In calendar Part P _C, by passing between the paper C in a state of being almost completed a pair of calender rolls 25, increasing its density and strength finishing the surface of the paper C smooth.

In the reel part P _R, wound resulting paper C, i.e. the base paper C as a single tissue paper into a roll. Prepare two rolls of tissue paper obtained through this process, pull them out in a separate process, overlap them, and cut them to the desired dimensions. A roll 10 is obtained.

In this case, it is possible to print the pattern 15 in forming a print or pattern 15 with respect to base paper C that moves between the calender part P _C and the reel-part P _R, or rewind the raw paper log . When printing a pattern 15 with a paper facility described above, the printing machine 26 is arranged between the calender part P _C and the reel-part P _R, the symbol on the cylinder 23 of the Yankee dryer 22 to the surface of the base paper C abutting side 15 is printed.

  In the embodiment described above, the pattern 15 is printed on the overlapping surface 11a of the front surface tissue 11, but it is also possible to print on the overlapping surface 12a of the back surface tissue 12, and the pattern is printed on only one or both. You may do it.

  It should be noted that the present invention should be construed only from the matters described in the claims, and in the above-described embodiment, all the changes and modifications included in the concept of the present invention are other than those described. Is possible. That is, all matters in the above-described embodiment are not intended to limit the present invention, and include any configuration not directly related to the present invention.
