Description

TECHNICAL FIELD The present invention relates to a film-wrapped tissue in which a pop-up bundle of tissue papers folded and stacked is wrapped in a film.

Tissue products in which a bundle of pop-up tissue paper is stored in a storage container include a so-called box tissue product in which the storage container is a paper box, and a film-wrapped tissue in which the packaging container is a packaging film made of resin.

This film-wrapped tissue has the advantage that the storage container that becomes waste after use can be made compact, and that it is easy to carry and that the unit selling price can be reduced.

The film-wrapped tissue has a single linear outlet-forming perforation extending along the lengthwise direction of the top surface of the wrapping film, which serves as a storage container, along the lengthwise direction of the top surface of the wrapping film. is formed, and this perforation is split at the time of use to form a slit-shaped outlet (Patent Document 1).

At the time of use, a part of the uppermost tissue paper in the bundle is exposed from the take-out port, and this exposed part is pulled out one by one to be used one by one.

However, since the film-wrapped tissue with such a linear slit-shaped outlet is lighter in weight than the paper box, the tissue paper is lifted together with the film and cannot be pulled out smoothly. Sometimes. Such a lifting phenomenon tends to occur when the slit length is shorter than the longitudinal direction of the top surface. Furthermore, the slit-shaped take-out port makes it difficult to take out the first sheet.

On the other hand, there are products in which the outlet is formed by die-cutting to have a certain width on the depth side (transverse direction) instead of having a slit shape, but such a product has an opening width of the outlet. However, when the number of tissue papers contained in the stack is reduced and the height of the bundle is lowered, the tissue paper is not partially exposed from the outlet, and the inside The phenomenon of falling into is likely to occur.

JP 2018-52559 A JP 2018-58654 A

Therefore, the main problem of the present invention is that the tissue paper does not easily fall into the packaging container even if the height of the bundle inside is reduced, and the packaging container is difficult to lift when the tissue paper is pulled out from the outlet, so that it can be removed. To provide a film-wrapped tissue in which a part of tissue paper next exposed from an outlet is likely to stand up after the tissue paper is pulled out from the outlet.

Means for solving the above problems are as follows.

The first means is
A film-wrapped tissue in which a bundle of pop-up tissue paper is wrapped with a resin wrapping film,
The top surface has perforations for forming an outlet formed annularly and along the longitudinal direction of the bundle,
Continuous or adjacent to the longitudinal edge of the outlet-forming perforation, parallel to or away from the center line extending in the transverse direction at the longitudinal center of the outlet-forming perforation The film-wrapped tissue is characterized by having slits or perforations that extend and do not reach the edge of the top surface.

The second means is
The longitudinal edge of the outlet-forming perforation has a curved shape that bulges toward the center in the transverse direction, and the curved portion extends outward from the area surrounded by the outlet-forming perforation. Alternatively, the film-wrapped tissue according to the first means has perforations.

A third way is
The film-wrapped tissue according to the first or second means has 2 to 5 slits or perforations per edge.

According to the present invention, even if the height of the bundle inside is reduced, the tissue paper does not easily fall into the packaging container, and when the tissue paper is pulled out from the outlet, it is difficult to lift the packaging container. To provide a film-wrapped tissue in which, after the paper is pulled out, a portion of the tissue paper next exposed from the take-out port tends to stand upright.

FIG. 3 is a plan view for explaining an outlet for the film-wrapped tissue according to the present invention; FIG. 4 is a plan view for explaining another form of the outlet of the film-wrapped tissue according to the present invention; FIG. 10 is a plan view for explaining a plurality of other forms of the outlet of the film-wrapped tissue according to the present invention; Fig. 2 is a perspective view showing a mode of use of the outlet of the film-wrapped tissue according to the present invention; It is a figure for demonstrating the example of the manufacturing method of the film packaging tissue which concerns on this invention.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7. FIG.

A film-wrapped tissue 1 according to the present invention includes a tissue paper bundle 3 formed by folding a plurality of sets of tissue paper 2 and wrapping them in a flexible resin-made wrapping film 4 .

In the tissue paper bundle 3 enclosed in the film-wrapped tissue 1 according to the present invention, the tissue paper 2 is folded in two, and the folded pieces 2B of the other tissue paper 2 positioned above and below are positioned on the folded inner side 2A. In this way, a plurality of tissue papers 2 are folded and stacked, and when one folded piece located at the top is pulled upward, another folded piece adjacent directly below it will move upward. It is a pop-up type tissue paper bundle 3 that is dragged and lifted.

This tissue paper bundle 3 can be manufactured by a known multi-stand type, rotary type interfolder. Each tissue paper 2 constituting the bundle 3 of the tissue paper 2 has a ply structure in which two to three sheets of thin paper having crepe are laminated to form a set. Also, the tissue paper 2 is of a dry type, not a so-called wet type that is impregnated with a chemical solution.

On the other hand, the tissue paper bundle 3 according to the present invention has a pair of long side surfaces 3B on which the folded edges 2C of each tissue paper 2 are arranged, and a pair of short side surfaces 3A on which the folded edges 2C are not arranged. It has a substantially rectangular parallelepiped shape having a pair of flat surfaces (upper and lower surfaces) 3C that are connected to a side surface 3A and a longitudinal side surface 3B.

The packaging form of the film-wrapped tissue 1 according to the present invention is selected from known packaging types. Examples include three-side closed packaging, four-side closed packaging, gusset packaging, pillow packaging, and caramel packaging. Gusset packaging and pillow packaging are suitable, particularly the illustrated gusseted pillow packaging. In particular, the effect of the present invention is remarkable when the overlapped portion of the packaging film is heat-sealed at a position facing the short side 3A where the folding edge 2C of the tissue paper 2 in the tissue paper bundle 3 is not aligned. It is a gusseted pillow packaging in which a heat-sealed portion 30 is located.

The film-wrapped tissue 1 according to the present invention has an outlet-forming perforation 5 formed annularly along the bundle longitudinal direction 3y on the top surface 10 facing the uppermost tissue paper 2 of the bundle 3 of the packaging film 4. formed. An outlet 6 is formed in the top surface of the film-wrapped tissue 1 by tearing the outlet-forming perforations 5 . In the film-wrapped tissue 1 according to the present invention, since the tissue paper bundle 3 is of a pop-up type, when the top tissue paper 2 of the bundle 3 is pulled out by forming the outlet 6, the next tissue paper located immediately below it is exposed from the outlet 6.

The outlet-forming perforation 5 according to the present invention has an annular shape formed by die-cutting. The bundle 3 is elongated along the longitudinal direction 3y and has a length L2 shorter than the longitudinal length L1 of the bundle 3. As shown in FIG. Therefore, by splitting the outlet-forming perforations 5 and removing the area surrounded by the outlet-forming perforations 5, the outlet 6 having the same shape as the area surrounded by the outlet-forming perforations 5 is formed. It is formed. In addition, other perforations may be arranged within the range surrounded by the circularly arranged outlet-forming perforations so as to make it easier to remove the range.

The size of the range surrounded by the outlet-forming perforations 5 is not necessarily limited. 150 mm. The cut-tie ratio of the outlet-forming perforations is not particularly limited. Taking into account the material and thickness of the film, the thickness can be appropriately set to a range where it is easy to cut and peel.

Characteristically, the film-wrapped tissue 1 according to the present invention is continuous or adjacent to the longitudinal edges 5E, 5E of the outlet-forming perforation 5 and short at the longitudinal center of the outlet-forming perforation 5. Slits 50, 50 , . Perforations in which slits are formed by splitting instead of slits may be used. In the case of a slit, if it is continuous with the longitudinal edge portion 5E of the perforation for forming the outlet, the end of the slit should be continuous with the tie portion between the cut portion and the tie portion of the perforation, and the cut portion and the tie portion. should not be consecutive. In this way, the slit is formed only by removing the area surrounded by the outlet-forming perforations 5, and the slit may be unintentionally avoided when removing the area surrounded by the outlet-forming perforations 5. become smaller. In the case of perforations or when slits are provided close to each other, there is an advantage that unintentional slits cannot be avoided during the operation of removing the area surrounded by the outlet forming perforations 5 .

When the slit or the like 50 is formed in this way, the longitudinal edge of the outlet 6 can be separated by splitting the outlet forming perforations 5 and removing the area surrounded by the outlet forming perforations 5 . Soft flexible edge strips 6B, 6B are formed in the portions 6y, 6y.

Since such small edge pieces 6B, 6B are formed in the film-wrapped tissue 1 according to the present invention, when the tissue paper 2 is pulled out from the outlet 6, the slit 6A between the small edge pieces 6B, 6B widens. As a result, the pull-out resistance is reduced and the roll can be pulled out smoothly, making it difficult to lift the whole packaging film 4 at the time of pull-out. At the same time, the edge 2E of the tissue paper 2 that is next pulled out and exposed from the outlet 6 enters the slit 6A and is pinched, or, for example, the small edge pieces 6B and 6B act like a check valve to hold the tissue paper. 2, and as shown in FIG. is likely to be in an upright state, and when it is used next time, part of the upright state is easy to grasp and it is difficult to fall into the packaging film 4.例文帳に追加The length of the slit 50 is 2 to 20 mm, preferably 3 to 10 mm, particularly preferably 3 to 6 mm. If it is less than 2 mm, the support by the small edge piece 6B and the opening of the slit 6A may not be sufficient, and the tissue paper drawing resistance may be lowered and the tissue paper 2 may not be sufficiently supported. On the other hand, if it exceeds 20 mm, there is a high possibility that the tissue paper 2 will not be sufficiently supported.

It is desirable that the number of slits 50 is 2 to 5 per one edge 5E. 3 to 6 small edge pieces 6B are formed, and when the tissue paper 2 is pulled out from the outlet 6, the space between the slits 6A can be widened according to the complicated shape change of the tissue paper 2, so that the tissue paper 2 can be pulled out more smoothly. Furthermore, it becomes easy to adapt to and support the shape of the edge 2E of the next tissue paper 2 that is pulled out from the outlet 6 and exposed. If the number exceeds 5, there is a high possibility that the packaging film 4 will easily tear unintentionally. If two to five slits or the like are to be formed as described above, it is desirable that they be symmetrical about the center in the transverse direction, or radially with equal intervals. The edges of the tissue paper 2 are more likely to be evenly supported, and the uprightness of the tissue paper is enhanced.

Here, the specific shape of the outlet-forming perforation 5 is not necessarily limited, but may be an elliptical shape, an elongated rectangular shape, or an elongated rectangular shape with cut corners. As a preferred form, the longitudinal edges 5E, 5E of the outlet-forming perforation 5 preferably form a curved shape, such as a semicircle, which bulges toward the center in the lateral direction. The form shown in FIG. 1 has a curved shape in which the end portions of a pair of two perforations 5A, 5A that are separated from each other by a predetermined distance parallel to the longitudinal direction bulge toward the center in the lateral direction of a semicircle. It's becoming Further, the pair of two perforations 5A, 5A parallel to the longitudinal direction in FIG. 3 may be shaped so as to gradually bulge toward the center in the lateral direction. In this case, the outlet 6 has the shape shown in FIG. When the longitudinal edges 5E, 5E are curved like these, slits or the like 50 are formed from the curved portions toward the outside from the range surrounded by the outlet forming perforations 5. It is desirable to be

In this way, when the longitudinal edges 5E, 5E have a curved shape that bulges toward the center in the transverse direction, the uppermost tissue paper 2 of the bundle 3 is pulled out when the outlet 6 is used. Then, in the process in which a portion of the next tissue paper 2 positioned immediately below it is pulled out from the opening, the side edges 2E, 2E in the bundle longitudinal direction of the pulled out tissue paper 2 extend along the bulging shape. It is easy to be moved to involve them. As a result, part of the tissue paper 2 exposed from the outlet 6, for example, tends to form substantially cylindrical portions at both longitudinal direction side portions 2E, 2E as shown in FIG. The shape tends to be highly flexible, making it easier to grasp a part of the standing state and increasing the ability to prevent falling.

Here, the longitudinal length range L2 of the outlet-forming perforations 5 according to the present invention is desirably 80% to 90% of the longitudinal length L1 of the bundle 3, more preferably 84%. It is desirable to be ~88%. In such a range, after the tissue paper is pulled out from the outlet 6, the edge of the tissue paper 2 next exposed from the outlet 6 is easily supported by the longitudinal edge of the outlet 6. is increased, and the resistance when pulling out the tissue paper from the outlet 6 is not excessively increased.

Specific flexible resin film materials constituting the packaging film 4 according to the present invention include polyethylene film, polypropylene film, polyester film, polyethylene terephthalate film, nylon film, vinylidene chloride film, and ethylene vinyl alcohol copolymer. single-layer films, suitably laminated laminate films containing these films, and gas barrier films obtained by subjecting these films to surface treatment such as aluminum vapor deposition can be exemplified. Polypropylene film and polyethylene film are suitable from the viewpoint of cost. The thickness of the film material is desirably 20-60 μm. The slit is easily opened, the tissue paper is easily pulled out smoothly, and the tissue paper 2 is preferably easily supported by the small edge piece 6B. If the thickness is less than 20 μm, there is a problem that the film is easily torn during use. If the thickness is 60 μm or more, the film becomes hard and usability deteriorates. The thickness of the film material is measured using a dial thickness gauge (thickness measuring instrument) "PEACOCK G-1A type" (manufactured by Ozaki Seisakusho) under standard conditions. The specific measurement procedure is to check that there is no dust or dust between the plunger and the measuring table, lower the plunger on the measuring table, move the memory of the dial thickness gauge, and set the zero point. Combine, then lift the plunger to place the sample on the test bench and slowly lower the plunger to read the current gauge. At this time, only the plunger is placed. Let thickness be the average value obtained by performing a measurement 10 times.

Moreover, it is desirable that the physical properties of the tissue paper bundle 3 and the tissue paper 2 in the film-wrapped tissue 1 according to the present invention are as follows. Even with the small edge piece 6B, the tissue paper can be pulled out smoothly, and the tissue paper 2 can be preferably easily supported by the small edge piece 6B.

The number of plies and the number of sets of the tissue papers 2 constituting the tissue paper bundle 3 is preferably 100 to 220 sets, with 2 plies (two sheets stacked) as one set. The shape of the tissue paper bundle 3 is preferably 30 to 50 mm in height, 155 to 215 mm in length in the longitudinal direction, and 100 to 130 mm in length in the width direction. It is possible to obtain a sufficiently necessary number of sets as a tissue paper product, and it is possible to obtain a sufficient size and number of sets to be used as the tissue paper 2, and the number of sets constituting a bundle is reduced by use. However, it becomes extremely difficult to fall.

Moreover, it is desirable that the tissue paper bundle 3 is manufactured by a rotary interfolder. When a bundle is produced by a rotary interfolder, the MD direction of the tissue paper and the width direction of the bundle are aligned. That is, when part of the tissue paper exposed from the outlet is in an upright state, the MD direction, which has high paper strength, is the vertical direction, so part of the tissue paper can be easily maintained in a self-supporting state and prevented from falling down. easier to be

In addition, the tissue paper 2 according to the present invention may be a chemical solution application type to which a moisturizer or the like is applied, but the present invention is a general-purpose non-moisturizing tissue paper 2 to which a moisturizer or the like is not applied. is preferable because it tends to be more independent.

It is desirable that the basis weight per sheet of thin paper forming each ply of the tissue paper 2 is 10.0 to 15.0 g/m ² . The basis weight here is according to the measuring method of JIS P 8124 (1998). From the viewpoint of the feeling of use as tissue paper, it is desirable that the specific paper thickness of a set of tissue paper is in the range of 80 to 200 μm.

To measure the paper thickness, the tissue paper was sufficiently conditioned under the conditions of JIS P 8111 (1998), and then under the same conditions, a dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Seisakusho) was used. shall be the value measured using The specific measurement procedure is to check that there is no dust or dust between the plunger and the measuring table, lower the plunger on the measuring table, move the memory of the dial thickness gauge, and set the zero point. Combine, then lift the plunger to place the sample on the test bench and slowly lower the plunger to read the current gauge. At this time, only the plunger is placed. The terminal of the plunger is made of metal and its circular plane with a diameter of 10 mm is perpendicular to the plane of the paper. In addition, let thickness be the average value obtained by performing a measurement 10 times. If the basis weight and paper thickness are within the above ranges, the tissue paper can be pulled out smoothly even with the small edge strips 6B, and the tissue paper can be favorably supported by the small edge strips.

The dry paper strength of the tissue paper 2 is preferably 200 to 700 cN/25 mm in the MD direction and 50 to 300 cN/25 mm in the CD direction. In addition, the paper strength can be achieved by adjusting papermaking raw materials such as adding a paper strength agent at the time of papermaking. Moreover, it is desirable that the elongation percentage (tensile elongation at break) of the tissue paper in the MD direction is 5 to 20%. Even if there is a small edge piece, the tissue paper can be pulled out smoothly, and the small edge piece tends to favorably support the tissue paper.

Also, the tissue paper 2 preferably has a softness of 0.90 to 1.30 cN/100 mm. Softness is one of the indices of softness. The softness according to the present invention is measured according to the handle-o-meter method according to JIS L 1096 E method. However, the size of the test piece shall be 100 mm×100 mm, and the clearance shall be 5 mm. The measurement is made five times each in the vertical direction and the horizontal direction for one ply, and the average value of all ten times is expressed in units of cN/100 mm. Within this softness range, the tissue paper can be pulled out smoothly.

The tissue paper 2 preferably has an MMD of 7.5 to 9.0. MMD is a measure of smoothness. When the MMD is within the above range, the slipperiness with the packaging film is moderate, and when the softness is within this range, the tissue paper is easily guided by the guide edge. The MMD is a value measured using friction testers KES-SE, KES-SESRU manufactured by Kato Tech Co., Ltd., and their equivalents. MMD is the degree of variation from MIU (mean coefficient of friction), and the smaller the value, the smoother. The measurement conditions according to the present invention are as follows: the contact surface of the friction element is brought into contact with the surface of the measurement sample to which a tension of 20 g/cm is applied in a predetermined direction with a contact pressure of 25 g; Move 2 cm in the same direction at a speed of 0.1 cm/s. The measurement is made 10 times, and the average value is taken as MMD. A piano wire sensor, which is a standard accessory, is used as the friction element. This piano wire sensor has a contact surface formed by adjoining 20 piano wires each having a diameter of 0.5 mm and having a length and a width of 10 mm. The contact surface is formed with a unit bulging portion whose tip is formed of 20 piano wires (having a radius of curvature of 0.25 mm).

The raw material pulp of the thin paper constituting the tissue paper 2 is a blend of softwood-derived pulp such as NBKP, NUKP, and NOKP and hardwood-derived pulp such as LBKP, LUKP, and LOKP. Waste paper pulp may be blended, but in terms of texture, etc., it is preferable to consist only of NBKP and LBKP. The mixing ratio is preferably NBKP:LBKP=10:90 to 80:20, more preferably NBKP:LBKP=20:80 to 60:40.

The film-wrapped tissue 1 according to the present invention can be manufactured particularly as shown in FIG. First, the tissue paper 2 is folded in half by an interfolder such as a multi-stand type or a rotary type, and the folded pieces 2B of the other tissue papers 2 positioned above and below are positioned inside the folded inside 2A. The tissue papers 2 are folded and stacked to form a pop-up type tissue paper bundle 3 having a substantially rectangular parallelepiped shape.

Next, this tissue paper bundle 3 is conveyed with the lateral side 3A where the folded edge 2C of the tissue paper 2 is not aligned in the front-rear direction. This transportation can be performed by a belt conveyor or the like. At the same time, the continuous packaging film 14 is fed out from the original film roll 40 around which the continuous long packaging film 14 is wound, and the die-cut roll 16 feeds the conveyed continuous packaging film 14 with an outlet for the tissue paper 2 at regular intervals. The outlet forming perforations 5 and the slits 50 and the like, which will be the forming portion, are formed. The shape of the outlet forming perforations 5 and the slits 50 may be formed appropriately according to the pattern of the cutter blade on the peripheral surface of the die-cut roll. Although not shown, the outlet forming perforations 5 and the slits 50 are formed not by the die-cut roll 16 but by stop-and-go conveyance of the continuous packaging film, and by pressing a die-cut plate at the time of stop. good too.

Next, the transport direction of the tissue paper bundle 3 and the transport direction of the continuous packaging film 14 are made to coincide, and while the tissue paper bundle 3 is being transported, the tissue paper bundle 3 is placed below the outlet forming perforations 5 of the continuous packaging film. , the tissue paper bundle 3 is wrapped around the edge of the continuous packaging film 14, and the tissue paper bundle 3 is heat-sealed at a position facing the short side 3A of the tissue paper bundle 3, and at the same time as this heat-sealing treatment Alternatively, it is then cut into individual packages (packaging process). A gusset may be formed on the longitudinal side 3B side of the tissue paper bundle 3 at the time of heat-sealing to provide pillow packaging with a gusset.

Next, with respect to the film-wrapped tissue according to the present invention and the film-wrapped tissue of the comparative example, the tissue paper contained therein was pulled out, and the take-out resistance value, film floatation and sagging were tested. The structure of the tissue paper and the bundle and the form of packaging by the wrapping film were all the same, and only the arrangement form of the outlet and the slit was different in each example. The arrangement form of the outlet and the slit is as shown in FIG. 5A for Reference Example 1, FIG. 5B for Example 2, FIG. Example 5 is shown in FIG. 5(E), and Example 6 is shown in FIG. 5(F). In Comparative Example 1, the perforations were formed as a straight line instead of in a circular shape to form a slit-shaped outlet. In Comparative Example 2, no slit was formed in FIG. 5(A). The form of the film-wrapped tissue, the size of the outlet, the shape and physical properties of the bundle of tissue paper to be wrapped, the physical properties of the wrapping film, etc., according to more specific examples are shown in Table 1 below together with the results.

The extraction resistance value was measured by the following procedures (1) to (3).

(1) A part of the tissue paper exposed from the outlet is clamped and fixed with a clip (manufactured by Kokuyo Co., Ltd., eyeball clip Cree 17).

(2) Pass the hook of a push-pull gauge (manufactured by Imada Co., Ltd., model number Z2-20) through one hole of the clip, pull the push-pull gauge vertically upward, and the tissue in 0.4 to 0.6 seconds. pull out and remove. Measure the maximum value of resistance during the take-out operation.

(3) Calculate the average value of the 1st to 5th sets and the average value of the 6th to 10th sets from the top layer of the bundle.

The floating of the film was determined by continuously pulling out the tissue paper constituting the bundle and measuring the number of sets from the top of the bundle when the wrapping film was lifted.

The drop is the number of sets from the top of the bundle when the operation of pulling out the tissue paper that makes up the bundle is continuously performed, and a part of the tissue paper next to the pulled-out tissue paper is not exposed from the outlet and falls inside. was measured.

As shown in Table 1, the length in the longitudinal direction of the outlet (described as the width of the outlet in the table) in the reference example, the example, and the comparative example is the same at 135 mm, and the length in the longitudinal direction of the bundle ( The width of the web dimension) is also the same as 179 mm, and the length of the outlet in the longitudinal direction is shorter than the length of the bundle in the longitudinal direction . 2, the film floating occurred only in the number of sets much closer to the bottom than in the comparative example. As for depression, in Example 4 where the slit length is as long as 10 mm, depression is observed in the last set of the 159th set, but it can be said that it is extremely unlikely to occur. In particular, even though the tissue paper has a low pull-out resistance, it is difficult for the tissue paper to drop. In addition, in the outlet shapes of Comparative Examples 1 and 2, the longitudinal length of the outlet is approximately the same as the length between the slit ends (135 m + 10 m + 10 m = 155 mm) located at the end in the longitudinal direction in Example 4 in the table. Then, it has been found that the depression occurs earlier than in the fourth embodiment.

Thus, in the film-wrapped tissue according to the present invention, the small edge piece formed by the slit or the like functions, and even if the height of the bundle inside is lowered, the tissue paper does not easily fall into the packaging container and can be removed. When the tissue paper is pulled out from the outlet, the packaging container is difficult to lift, and after the tissue paper is pulled out from the outlet, a part of the tissue paper next exposed from the outlet is likely to be in an upright state.
