Description

  The present invention relates to a tissue paper product in which a bundle of tissue paper to which a moisturizing chemical is applied is stored in a storage box.

  A bundle of a plurality of tissue papers is stored in a storage box, and one sheet of tissue paper is sequentially formed from a take-out port provided on the upper surface of the storage box (also referred to as a carton box or a carton). Tissue paper products that are pulled out and used one by one) are well known. The take-out method is a pop-up type in which when one piece is taken out, the next piece is continuously drawn out from the take-out port.

  Among these tissue paper products, there is a chemical liquid imparting type in which a moisturizing chemical liquid that imparts moisture retention and flexibility is imparted to the tissue paper, which is superior to those of general-purpose products in moist feeling and softness.

  There are various moisturizing chemicals that impart moisture retention and flexibility to tissue paper, but aqueous chemicals mainly composed of water and polyol (also referred to as “aqueous lotion” or “lotion chemical”) are often used. Aqueous chemicals are excellent in affinity with the pulp fibers constituting the sheet when applied to the sheet, impregnated in the thickness direction of the sheet (also referred to as the Z direction), and moisturized by the moisturizing chemical solution. And give softness.

  However, tissue paper products using conventional aqueous chemicals do not have sufficient moisture absorption in a low-humidity environment, and moisture may not be sufficiently taken into or released from the tissue paper. There was a problem that it was difficult to feel moist and soft. Although the hygroscopic effect can be enhanced by increasing the amount of the hygroscopic component in the aqueous chemical solution, this causes a problem that the tissue paper becomes sticky in a high humidity environment.

  Then, the main subject of this invention is providing the tissue paper product which can adjust the moisture retention condition of tissue paper according to the surrounding humidity environment.

The present invention that has solved the above problems is as follows.
[Invention of Claim 1]
A sheet material provided with a slit on the inner side surface of the upper surface of the paper box in which the upper surface is formed with a tearing perforation line for forming a take-out opening is located within a range surrounded by the perforation perforation line. A tissue paper product having a storage box pasted in this manner, and a tissue paper bundle formed by folding and stacking tissue paper to which an aqueous chemical solution stored in the storage box is provided,
A hinge lid that allows the opening to be opened and closed together with the takeout opening is formed by tearing the tearing perforation line, and moisture is absorbed on the inner surface of the upper surface of the paper box in the range surrounded by the tearing perforation line. A moisture retention adjusting agent for holding and releasing moisture is applied, and when the take-out port is closed by the hinge lid, the moisture retention adjusting agent faces the inner surface of the storage box and the humidity in the storage box is adjusted. Featured tissue paper products.

The tissue paper product according to any one of claims 1 to 3.

[Function and effect]
In the present invention, it is formed in the shape of a hinge lid that can be opened and closed together with the take-out port by cleaving the perforation line for tearing. Therefore, by closing the take-out port with the hinge lid, the space in the storage box can be substantially blocked from the outside air, and the flow of the inside and outside air can be extremely reduced. Thereby, even if the space outside the storage box is in a dry environment, the moisture of the tissue paper in the storage box is prevented from being diffused to the outside through the outlet.

  Furthermore, in the present invention, a moisture retention adjusting agent that absorbs moisture, retains and dissipates moisture is applied to the inner surface of the upper surface of the paper box in the range surrounded by the perforation line for cleavage. Therefore, when the take-out port is closed by the hinge lid, the moisturizing adjustment agent faces the inner surface of the storage box. Then, by closing the hinge lid shape as described above, in the storage box space, the flow of outside air from the storage box outer space is extremely reduced. Therefore, in this closed state, the storage box inner space is reduced to the storage box outer space. Regardless of humidity, it becomes possible to adjust with a moisture retention adjusting agent.

  Further, to explain this point, tissue paper products are used with the hinge lid open so that the tissue paper can be pulled out of the storage box. At this time, since the moisture retention adjusting agent of the present invention is exposed not to the inside of the storage box but to the outside of the storage box, it absorbs moisture from the surrounding air and holds it.

  When tissue paper products are not used, by closing the hinge lid, the moisture retention agent that contains and retains sufficient moisture will face the space inside the storage box. In the dry state, moisture is dissipated to increase the humidity in the storage box, and the tissue paper is prevented from drying.

  In addition, although the sheet | seat material is affixed at the taking-out opening, the effect of this invention is achieved through the slit provided in the sheet | seat material. Moreover, if it is moisture permeability in the sheet | seat material used for a general tissue paper product, the effect of this invention can fully be achieved irrespective of the presence or absence of a slit.

  Here, in particular, it is desirable that the moisture retention adjusting agent has a lower hygroscopic power than tissue paper and has a lower moisture absorption rate. When the moisture absorption capacity is lower than tissue paper in this way, moisture retention adjustment is achieved as the space inside the storage box becomes dry by the tissue paper absorbing moisture in the storage box when facing the storage box. The water can be effectively dissipated from the agent, and the water can be transferred to the tissue paper.

  In particular, when the humidity in the surrounding environment is high, the moisture in the storage box space is saturated, and the moisture retention regulator does not excessively retain the tissue paper. Rather, if the moisture retention amount of the moisture retention regulator is sufficient, moisture in the storage box space can be absorbed to prevent stickiness due to excessive moisture absorption of the tissue paper.

  Here, preferable moisturizing agents capable of easily adjusting the moisture content of the tissue paper by adjusting the humidity of the storage box internal space by the above mechanism are heteropolysaccharides such as mucopolysaccharides such as hyaluronic acid and chondroitin, glucomannan and agar. Desirably, it is at least one selected from the group of saccharides. These can retain a large amount of moisture in a small amount, and act to give moisture to the tissue paper when the tissue paper inside is in a dry state.

  As described above, according to the present invention, there is provided a tissue paper product that can adjust the moisture retention of the tissue paper according to the surrounding humidity environment.

It is a perspective view of the tissue paper product concerning the present invention. It is an example of the expanded view of the storage box which concerns on this invention. It is a perspective view for demonstrating especially the structure of the side short surface of the storage box which concerns on this invention, and an extraction port. It is a perspective view at the time of use of the tissue paper product concerning this invention. It is the figure which represented the AA cross section of FIG. 4 typically. It is the figure which looked at the upper surface from the box inner side for demonstrating the moisture retention regulator provision part which concerns on this invention. It is sectional drawing which shows the state which closed the hinge lid | cover especially of the tissue paper products based on this invention. It is the other figure which looked at the upper surface from the storage box inner side for demonstrating the aspect in which the film which coat | covers the moisture retention regulator provision part which concerns on this invention was affixed.

  Next, embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 8 show a tissue paper product 100 according to the present invention.

  In the tissue paper product 100 according to the present embodiment, the tissue paper bundle 2 formed by folding and laminating a plurality of tissue papers 2t, 2t... Is formed on the upper surface 11 with a tearing perforation line 20 for forming an outlet. When the tissue paper 2t is stored in the storage box 1 and is taken out from the take-out port 20X during use, a part of the lower-layer tissue paper stacked adjacently is exposed from the take-out port 20X. It is.

  The tissue paper bundle 2 is formed by stacking square tissue papers 2t so that they are substantially folded in two, and the edges of the folded pieces are positioned on the folded inner surface of the adjacent tissue paper. is there. Here, the term “substantially” means that a slight fold of the edge formed in manufacturing is allowed.

  In the tissue paper bundle 2 having this laminated structure, when one folded piece positioned at the top is pulled upward, the other folded piece adjacent immediately below it is pulled upward by friction and lifted. The tissue paper bundle 2 having such a structure is stored with its uppermost surface facing the upper surface of the storage box 1 having the extraction port 20X on the upper surface 11 described above. When the set (one set on the top surface) is pulled out, a part of the other set located immediately below is exposed. Note that the number of tissue papers 2t in the present invention is not limited, but a typical number of sheets of this type of product is 120 to 240 sets. This tissue paper bundle 2 can be manufactured by a known interfolder of a multi-stand type or a rotary type.

  On the other hand, the tissue paper 2t constituting the tissue paper bundle 2 has a ply structure in which two to three thin papers are laminated. The raw pulp of the thin paper is a mixture of NBKP and LBKP, and may be appropriately combined with waste paper pulp. However, in terms of texture and the like, it is preferably composed only of NBKP and LBKP. In this case, the blending ratio is preferably NBKP: LBKP = 20: 80 to 80:20, and particularly preferably NBKP: LBKP = 30: 70 to 60:40.

The rice tsubo per thin paper constituting each ply of the tissue paper 2t is preferably 10 to 25 g / m ² , more preferably 12 to 18 g / m ² in a state including a chemical solution. If the rice tsubo is less than 10 g / m ² , it is preferable from the viewpoint of improving softness, but it is difficult to ensure adequate strength that can withstand use. On the other hand, when the rice tsubo exceeds 25 g / m ² , the entire paper becomes hard, and a feeling of stickiness is generated, resulting in poor touch. In addition, the US tsubo is based on the JIS P 8124 (1998) US tsubo measurement method.

  On the other hand, the paper thickness of the tissue paper is desirably 100 to 180 μm, more preferably 120 to 150 μm in a two-ply state. If the paper thickness is less than 100 μm, it is preferable from the viewpoint of improving the softness, but it is difficult to ensure adequate strength as tissue paper. On the other hand, if it exceeds 180 μm, the texture of the tissue paper is deteriorated, and a feeling of tingling is generated during use.

  As a method for measuring the paper thickness, the specimen is fully conditioned under the conditions of JIS P 8111 (1998), and then the dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho) under the same conditions. It shall be measured in the state of 2 plies using. Specifically, confirm that there is no dust, dust, etc. between the plunger and the measuring table, lower the plunger on the measuring table, move the memory of the dial thickness gauge to adjust the zero point, and then Raise the plunger, place the sample on the test bench, slowly lower the plunger and read the gauge at that time. At this time, only the plunger is placed. The terminal of the plunger is made of metal so that a circular plane having a diameter of 10 mm is perpendicular to the plane of the paper, and the load at the time of measuring the paper thickness is about 70 gf. The paper thickness is an average value obtained by performing measurement 10 times.

  On the other hand, the tissue paper according to the present invention is provided with an aqueous chemical solution, and is a polyol as a main moisture-absorbing component that brings about its moisturizing effect. Examples of the polyol include glycerin, diglycerin, propylene glycol, 1,3-butylene glycol, polyethylene glycol, and derivatives thereof such as saccharides such as sorbitol, glucose, xylitol, maltose, maltitol, mannitol, and trehalose. Illustrated. Of these, glycerin is effective.

The content of the polyol in the tissue paper according to the present invention is preferably 1.5 to 5.5 g / m ² when absolutely dry, and the content is preferably 8 to 24% by mass. Within this range, an improvement in moist and soft feeling due to moisture absorption by the polyol can be obtained.

  On the other hand, the tissue paper according to the present invention may contain an appropriate functional drug in addition to the polyol. Examples of this functional agent include surfactants, inorganic and organic fine particle powders, and oily components. The surfactant has the effect of giving the tissue paper more flexibility and smoothing the surface. As the surfactant, an anionic surfactant, a cationic surfactant, and a zwitterionic surfactant can be used. Inorganic and organic fine particle powders have a smooth surface. The oil component has a function of improving lubricity, and a high-absorbing alcohol such as liquid paraffin, cetanol, stearyl alcohol, oleyl alcohol and the like can be used.

  On the other hand, the storage box 1 for storing a bundle of tissue papers is a rectangular parallelepiped box called a carton box, and has a product appearance. This storage box 1 has a paper box 10 having a tearing perforation line 20 for forming an extraction opening 20X on the upper surface 11, and a sheet material 30 that covers a range 20a surrounded by the perforation line 20 from the inside of the paper box. ing.

  The paper box 10 is a substantially paper box that forms an outline of the storage box 1, and the structure of the paper box of the known storage box is adopted for the size, shape, developed shape, and the like. The size of a general storage box is approximately 110 to 320 mm for the long edge L1, 70 to 200 mm for the short edge L2, and about 40 to 150 mm for the height L3. The storage box 1 according to the present invention also has this size. can do.

The base material of the paper box 10 can be a known paper material mainly made of various pulps such as virgin pulp and waste paper pulp, and the suitable material of the paper box 10 is a coat having a basis weight of 250 to 500 g / m ² . Cardboard.

  As shown in FIGS. 2 and 3, the paper box 10 has a structure in which the bottom surface 12 and one long side surface 13 are glued with a glue margin 12A to form a cylindrical shape, and then the top surface 11, the bottom surface 12, and the length connecting them. Each of the flaps F, F... Extending from the side surface 13 is folded back toward the inner surface of the box, and the contact portion of each flap F, F. . The paper box 10 of the present invention is not limited to this structure.

  On the other hand, in the storage box 1, the tearing perforation line 20 formed on the upper surface of the paper box 10 has an annular or substantially C shape and is configured with an appropriate cut tie ratio. The illustrated form is an example in which perforation lines for tearing are arranged in an annular shape. The perforation line 20 for cleaving can be constituted by a double perforation line, a zipper perforation line, or the like in addition to a normal perforation line. Only a part may be a double perforation line.

  The perforation line 20 for tearing has long sides 21 and 21 extending in the longitudinal direction of the paper box and short sides 22 and 22 parallel to the short edges connecting the ends of the long sides 21 and 21. The shape of the range 20 a surrounded by the perforation line 20 is an appropriate shape having a long direction along the longitudinal direction of the storage box 1. In general, a slightly elongated rectangular shape along the longitudinal direction of the storage box 1 or the central part of the long sides 21 and 21 of the rectangle is slightly expanded outward to form an arch shape, and a shape close to an ellipse It is a thing. The illustrated form is the latter example.

  As can be understood from FIGS. 1 and 3 to 5, the tissue paper product according to the present invention has a hinge lid 20 </ b> F that can open and close the take-out opening together with the take-out opening by tearing the perforation line 20 for tearing. To be formed. If the perforation line 20 for tearing is arranged in a ring shape as shown in the figure, a part of the perforation line 20 for cleavage is left uncut, and the uncut portion is used as the hinge shaft 20G of the hinge lid 20F. And it is sufficient. Although not shown, when the tearing perforation line 20 is arranged in a ring shape, if a part of the tearing perforation line 20 is arranged in a straight line, the straight part becomes the hinge shaft 20G. The hinge lid 20F can be formed effectively. Furthermore, if the perforation perforation line 20 is arranged in a substantially C shape instead of an annular shape so that the perforation perforation line 20 cannot be completely cut off, the hinge lid 20F is not formed by mistake. Thus, it is possible to prevent an erroneous operation of cutting off the range 20a surrounded by the perforation line 20 for tearing. In this case, since the hinge lid is formed in such a manner that both ends of the substantially C-shaped tearing perforation line 20 are hinge axes, a crease or the like is formed between both ends of the perforating perforation line 20 in a substantially C-shape. If formed, it becomes easier to form the hinge lid 20F.

  Thus, in the tissue paper product 100 according to the present invention, by forming the hinge lid 20F that can be freely opened and closed, particularly as shown in FIG. 7, by closing the take-out port 20X with the hinge lid 20F, The space inside the storage box can be substantially shielded from the outside air to greatly reduce the circulation of the air inside and outside. Especially, even if the space outside the storage box is in a dry environment, the tissue paper 2t in the storage box or a bundle 2 thereof Is prevented from being diffused into the space outside the storage box through the take-out port 20X and the slit 31.

  Further, in the tissue paper product 100 according to the present invention, the moisture retention adjusting agent 40 is characteristically provided on the inner side surface 11i of the upper surface of the paper box 10 in the range 20a surrounded by the tearing perforation line 20 of the storage box 1 (paper box 10). Has been granted. The moisturizing regulator 40 absorbs moisture, retains and dissipates moisture, and in particular, can absorb moisture in the outer space of the storage box and can dissipate moisture into the inner space of the storage box. ing.

  In the storage box 10 of the present embodiment, the range 20a surrounded by the tearing perforation line 20 is the hinge lid 20F as described above. Therefore, in the state where the hinge lid 20F is opened, the moisture retention adjusting agent 40 is in the space outside the storage box. On the other hand, when the hinge lid 20F is closed, the moisture retention adjusting agent 40 in a state of retaining the moisture comes to face the inner surface of the storage box. Therefore, when the moisture retaining conditioner 40 is exposed to the outside, the moisture in the surrounding environment is absorbed to retain the moisture, and the space in the storage box is dry with the hinge lid 20F closed. Then, the retained moisture is diffused, and the moisture retaining condition of the tissue paper 2t in the storage box is adjusted to an appropriate range. This operation will be further described. The tissue paper product 100 is normally used with the hinge lid 20F opened so that the tissue paper 2t can be pulled out from the storage box 1. When the hinge lid 20F is open, the moisture retention adjusting agent 40 is exposed to the space outside the storage box. At this time, even if the surrounding environment is dry, the moisture retention adjusting agent 40 retains its own moisture absorption capacity and moisture retention. It absorbs and retains moisture from the surrounding environment to some extent according to force. At this time, the tissue paper 2t to which the aqueous chemical solution in the storage box has been applied is already out of the dry storage box through the sheet material of the take-out port 20X or through the slit 31 from a state already containing some moisture. Moisture taken into the water gradually dissipates and dries.

  On the other hand, when the tissue paper product 100 is not used, for example, when the hinge lid 20F is closed at night or the like, the moisture retention adjusting agent 40 that sufficiently contains and holds moisture comes to face the inner space of the storage box. At the same time, by closing the hinge lid 20F, the airtightness with the outside of the space inside the storage box is enhanced, and the diffusion of moisture from the tissue paper 2t or the bundle 2 to the space outside the storage box is stopped. At this time, since the space inside the storage box is very narrow compared to the space outside the storage box, the diffusion of moisture from the tissue paper 2t or its bundle 2 is stopped in the storage box space, and the moisture in the space is immediately Saturated and dried tissue paper will try to take up moisture in the narrow space. That is, by closing the hinge lid 20F, the space in the storage box is stopped from releasing moisture from the tissue paper 2t or the bundle 2 and the action to take in moisture is increased. Then, when the moisture retention conditioner 40 that has sufficiently taken in moisture faces the dried space, the sheet material 30 is transmitted from the moisture retention conditioner 40 or from the slit 31 of the sheet material 30 to the storage box. Moisture is diffused into the inner space, and the tissue paper 2t or the bundle 2 is moisturized again.

  In the tissue paper product 100 of the present embodiment, since the topmost tissue paper 2t is partially exposed to the outside from the slit 31 after the start of use, as shown in FIG. When the lid 20F is closed, the exposed portion may be sandwiched between the sheet material 30 and the hinge lid 20F. However, even in such a state, the tissue paper itself has a low density and is extremely dense. Therefore, the effect of the present invention can be sufficiently achieved.

  The amount and type of the moisturizing regulator 40 that exerts the above-described effects are imparted to the moisture retaining ability of the moisturizing regulator 40, moisture retention, moisture dissipation, the volume of the inner space of the storage box, and the tissue paper 2t. What is necessary is just to design suitably in relation to the moisture absorption power of the moisturizing component, moisture retention, moisture diffusibility, and the desired moisture retention condition of the tissue paper 2t.

  When selecting the type of moisturizer and determining the amount to be applied, a tissue paper bundle and a moisturizer are generally present in a space of about 24 L in an environment with a humidity of 20 to 70% and a temperature of 1 to 30 ° C. It is preferable that the moisture content of the tissue paper is adjusted to a range of 8 to 20% by mass when it is applied. With such a moisturizing agent 40, the adjustment of the moisturizing condition of the tissue paper 2t by the mechanism of the present invention is sufficiently exhibited.

  In selecting the moisturizing regulator, it is preferable that the moisture absorption capacity is lower than that of tissue paper and the moisture absorption rate is slower. Specifically, when the moisture content of tissue paper in the storage box space is less than or equal to the desired moisture content, moisture absorption and moisture diffusibility to dissipate moisture into the storage box space until the moisture content is reached. It is good to have. If it is such a moisturizing adjuster 40, it is easy to exhibit the adjustment of the moisture retaining condition of the tissue paper by the mechanism of the present invention. In addition, it is preferable that the speed of absorbing moisture in the space of the moisture retention regulator is slower than that of tissue paper. As a result, the moisture absorption from the space to the tissue paper and the moisture permeation to the space of the moisturizing adjuster differ in speed per hour, so the moisturizing adjuster adjusts the space in the storage box more gently. It is easier to exert the effect of adjusting the moisture retention condition of the tissue paper by the mechanism of the invention.

  In particular, the specific moisturizing regulator 40 capable of easily achieving the effects of the present invention is at least selected from the group of mucopolysaccharides such as hyaluronic acid and chondroitin, and heteropolysaccharides such as glucomannan and agar. It is a kind. These moisturizing regulators 40 take in moisture slowly over time as compared to polyol, which is the main moisturizing component of tissue paper, and retain a large amount of moisture to a gel or semi-gel form. Therefore, when the hinge lid is closed, the space inside the storage box is faced in a very wet state, so that the tissue paper can be easily adjusted to a sufficient moisturizing condition.

  As a specific application mode of the moisturizing agent adjusting agent 40, an embodiment in which the moisturizing adjusting agent is directly applied to the inner side surface 11i of the upper surface of the paper box 10 in the range 20a surrounded by the perforation line 20 for cleavage, a resin film sheet A mode in which a moisture retention adjusting agent is applied to one side of the substrate and the applied resin film sheet is adhered to the range 20a with an adhesive or the like in a direction in which the moisture retention adjusting agent application surface faces the inner side of the storage box. In the case of directly applying the moisturizing agent, it is desirable that at least the moisturizing agent application part is treated in advance with a water-resistant coating so that the moisturizing agent application part is not deformed by moisture absorption. The embodiment in which the resin film sheet is attached is preferable because the material of the paper box can be a general-purpose material, which facilitates production.

  On the other hand, in the storage box of this embodiment, as shown in FIG. 8, the inner surface 11i of the upper surface of the paper box in the range 20a surrounded by the tearing perforation line 20 is coated with a portion to which the moisture retention modifier 40 is applied. In addition, it is desirable that the protective film 50 is detachably attached so as to be airtight with respect to the inside of the storage box. If it does in this way, before opening the range 20a enclosed by the perforation line 20 for tearing and using the tissue paper product 100, it is prevented that the moisture retention auxiliary agent 40 absorbs moisture of the tissue paper inside. The The protective film 50 is a film having no moisture permeability, and examples thereof include vinylidene chloride film, polyethylene terephthalate, and ethylene-vinyl alcohol copolymer. In order to affix hermetically, for example, the protective film 50 may be affixed to the inner surface of the storage box so that the adhesive 51 is disposed so as to surround the portion to which the moisturizing agent 40 is applied as shown in the illustrated example.

  On the other hand, the sheet material 30 in the storage box 1 is larger than the range 20a surrounded by the tearing perforation line 20, for example, a rectangle or an ellipse, and particularly on the inner surface side of the upper surface of the paper box, In order not to affect the stripping, the adhesive is bonded by an adhesive 52 (not shown) outside the perforation line 20 for tearing. A slit 31 is formed in the sheet material 30, and the slit 31 is positioned along the longitudinal direction in a range 20 a surrounded by the tearing perforation line 20. Therefore, as shown in FIG. 3 and FIG. 4, by cutting off the range 20a surrounded by the tearing perforation line 20 along the tearing perforation line 20 into a hinge lid shape, the takeout port 20X is formed on the upper surface 11 of the paper box. At the same time, the sheet material 30 and the slit 31 formed in the sheet material 30 are exposed through the take-out port 20X.

  The tissue paper 2t and the like stored as a bundle in the storage box 1 are taken out one by one from the take-out port 20X through the slits 31 as shown in the drawing. And the said slit 31 supports a part of tissue paper 2t exposed from the taking-out opening 20X, and prevents falling into the inside of a storage box.

  Here, in the storage box 1 according to the present embodiment, since the sheet material 30 has a slit, even if the hinge lid 20F is closed, the tissue paper 2t or the tissue paper 2t from the moisturizing adjustment agent 40 is put into the storage box via the slit 31. Water can be sufficiently applied to the bundle 2. The sheet material 30 preferably has a certain degree of moisture permeability such as a polyethylene film or a polypropylene film. If it is such a film, the water | moisture content will be performed to the tissue paper from the moisturizing adjustment agent 40 through a film. Further, the sheet material 30 may be a moisture-permeable sheet material formed of a water-resistant fiber material such as water-resistant paper.

  The thickness of the sheet material 30 is preferably 10 to 200 μm. If the thickness is less than 10 μm, the strength is insufficient, and the probability of tearing or breaking when taking out the tissue paper 2t is high. Although there is no problem, it is difficult to take out and the cost is high.
