Description

  The present invention relates to a package containing sanitary thin paper such as tissue paper and a sanitary thin paper product.

  Conventionally, a portable pocket tissue in which a tissue paper is accommodated inside a package is known (see, for example, Patent Document 1). A perforation provided on one surface of the package of pocket tissue is cut open to form an outlet, and the tissue paper inside the package is drawn out through the outlet.

  The perforation needs a certain level of strength (hardness to break) in order to prevent it from breaking during pocket tissue manufacturing and transportation, but if the perforation is too strong, the perforation There is also a possibility that the tissue paper inside the package is torn when the paper is opened. Therefore, in order to make the tissue paper difficult to break, there is one in which the strength of the tissue paper itself is improved (see, for example, Patent Document 2).

Japanese Patent No. 5528045 JP 2013-111328 A

As shown in FIG.1 and FIG.2, the pocket tissue (sanitary thin paper product) 100 of Embodiment 1 is formed in the substantially rectangular parallelepiped shape long in the left-right direction, and is laminated | stacked several tissue paper (sanitary thin paper; FIG. 2) P,... Are packaged by the first package 1.

As shown in FIG. 2, the tissue paper P is folded in a “Z” shape at a position equally divided in the front-rear direction along the MD direction, and the two upper and lower free end sides are folded outward. Yes. Then, a plurality of tissue papers P,... Are formed such that the fold line on the lower free end side of one tissue paper P and the fold line on the free end side on the other tissue paper P abut each other. They are stacked in the vertical direction.
Further, the fold on the upper free end side of the uppermost tissue paper P is substantially parallel to a perforation M (described later) provided on the upper surface of the first packaging body 1, and in the vicinity of the perforation M (substantially) It is accommodated in the 1st package 1 so that it may be located directly under).
The tissue paper P has a ply structure in which, for example, two to three thin papers are laminated.

Further, the tissue paper P may be, for example, a moisturizing tissue paper (lotion tissue paper) obtained by impregnating a base paper with a chemical liquid mainly containing a moisturizing chemical at a predetermined ratio.
The moisturizing agent may be any one as long as it is generally used. Specifically, for example, glycerin, diglycerin, propylene glycol, 1,3-butylene glycol, polyethylene glycol And the like, saccharides such as sorbitol, glucose, xylitol, maltose, maltitol, mannitol, trehalose, etc., higher alcohols such as cetanol, stearyl alcohol, oleyl alcohol, liquid paraffin, and the like.
In addition, the base paper may be any paper as long as it is usually used as tissue paper, but preferably has good touch and flexibility, and has the required strength and absorbency. .

  The configuration of the tissue paper P described above is an example and is not limited to this, and any configuration may be used as long as it is a known one.

The 1st package 1 is formed in a substantially rectangular parallelepiped shape, and the perforation M is provided in the upper surface.
That is, the upper surface of the 1st package 1 comprises the perforation structure surface part 1a in which the perforation M was provided, and the said 1st in the front-back direction (short side direction) substantially central part of the perforation structure surface part 1a. A linear perforation M extending along the left-right direction (longitudinal direction) of the package 1 is provided. When the perforation M is cut open, an outlet (not shown) for the tissue paper P is formed, and a user puts a fingertip inside the first package 1 through the outlet and picks the tissue paper P. Thus, the tissue paper P is drawn out one by one.

  Moreover, the 1st package 1 is comprised from the film which consists of polyethylene, a non-axially stretched polypropylene, etc., for example. The polyethylene and the non-axially stretched polypropylene exemplified as the material of the first package 1 are merely examples, and are not limited to these. For example, any material used for a package of a general pocket tissue 100 may be used. If necessary, it can be arbitrarily changed.

Moreover, the inner surface facing the tissue paper P of the first package 1 is relatively slippery. For example, the coefficient of static friction between the inner surface of the first package 1 and the tissue paper P is preferably about 0.5 or less.
Here, as a method of making the inner surface of the first package 1 relatively slippery, for example, the smoothness of the inner surface is adjusted to a predetermined value, or the material of the first package 1 is selected and adjusted. The method etc. are mentioned.

It should be noted that at least a portion corresponding to the perforation constituting surface portion 1a of the inner surface of the first package 1 is not relatively the entire inner surface of the first package 1, but is relatively slippery.
Moreover, the measuring method of the static friction coefficient of the inner surface of the 1st package 1 is mentioned later.

On the outer surface of the perforation constituting surface portion 1a of the first package 1, two non-slip regions 2 and 2 are formed by sticking two non-slip films 2a and 2a.
The two non-slip regions 2 and 2 are provided on the outer surface of the perforation constituting surface portion 1a so as to be sandwiched in a direction intersecting with the extending direction (left-right direction) of the perforation M. Specifically, the two non-slip areas 2 and 2 are arranged at a predetermined distance from the perforation M in the front-rear direction and face each other so as to sandwich a substantially central portion in the extending direction of the perforation M. Is provided. Each of the two non-slip areas 2 and 2 has, for example, a substantially square shape and is arranged so that one side is substantially parallel to the extending direction of the perforation M.

The non-slip film 2a is formed using, for example, a relatively non-slip material such as synthetic rubber, polyurethane resin, or silicon resin. Moreover, in order to open the non-slip film 2a and the perforation M, the non-slip film 2a and artificial skin (bio skin plate, thickness 5 mm, length x width: 195 x 130 mm, model number: P001-001, View Co., Ltd.)

The synthetic rubber, polyurethane resin, and silicon resin exemplified as the material of the non-slip film 2a are only examples, and are not limited thereto, and can be arbitrarily changed as appropriate. Moreover, the timing which sticks the non-slip film 2a to the 1st package 1 may be in the case of manufacture of the film which comprises the 1st package 1, for example, and the tissue paper by the 1st package 1 may be sufficient as it. It may be after P is packaged.

In addition, the shapes, the separation distances, the arrangements, and the like of the two non-slip areas 2 and 2 described above are merely examples, and are not limited thereto, and can be arbitrarily changed as appropriate. For example, the two non-slip regions 2 and 2 may be arranged such that the end portions are butted in the front-rear direction across the perforation M, and are formed in a shape that is long in the front-rear direction. It may be formed (see FIG. 3A) or may be formed in a long shape so as to be substantially parallel to the extending direction of the perforation M (see FIG. 3B). Although not shown, the non-slip film 2a is attached to substantially the entire outer surface of the perforation constituting surface portion 1a, that is, two regions before and after the perforation M on the outer surface. Two non-slip regions 2, 2 may be configured.
Further, the surface of the non-slip film 2a may be uneven so that friction with a finger is increased. For example, even when a hemispherical recess or protrusion having a diameter of about 0.5 to 3 mm is processed on the surface. The whole may be processed into a wave shape or the like.
Moreover, the measuring method of the static friction coefficient of the non-slip area | region 2 is mentioned later.

(Calculation of finger pressing force when opening perforations)
Using the calculation results of the outer static friction coefficient (μs1) and the inner static friction coefficient (μs2) and the measurement results of the perforation breaking strength (gf) for the test pieces of Examples 1 to 20 and Comparative Examples 1 to 4, The estimated value of the finger pressing force (gf) when opening the perforation was calculated according to the following equation (1).
Finger pressing force when opening the perforation (P) =
Perforation breaking strength (F) / (outer static friction coefficient−inner static friction coefficient) Equation (1)

[Evaluation]
As shown in Table 1, in the polyethylene film alone, the outer static friction coefficient (μs1) at which the outer surface of the package is in contact with the finger is 0.87 (Comparative Example 1) and 0.61 (Comparative Example 2), As a non-slip film, 0.2mm thick synthetic rubber, 1mm thick polyurethane, 1mm thick synthetic rubber, 5mm thick synthetic rubber and 3mm thick silicon rubber are attached to each other. The coefficients (μs1) were 2.14, 2.06, 1.64, 1.23, and 1.73, respectively (Examples 1 to 5 and Examples 6 to 10).
Moreover, when the estimated value of finger pressing force; P (gf) at the time of opening the perforation was calculated, the polyethylene film alone was 797 (Comparative Example 1) and 850 (Comparative Example 2), As a non-slip film, 0.2 mm thick synthetic rubber, 1 mm thick polyurethane, 1 mm thick synthetic rubber, 5 mm thick synthetic rubber, and 3 mm thick silicon rubber are attached to the finger. The force P (gf) was 267, 279, 362, 510, and 340 in Examples 1 to 5, respectively, and 147, 154, 201, 289, and 189 in Examples 6 to 10 (see Table 1).
That is, by sticking a non-slip film to a polyethylene film, the outer static friction coefficient is increased, and as a result, it is considered that the finger pressing force when opening the perforation is reduced (Comparative Examples 1 and 2). Examples 1 to 5, Examples 6 to 10).

Similarly, the non-axially stretched polypropylene film alone has an outer static friction coefficient (μs1) of 1.26 (Comparative Example 3) and 1.09 (Comparative Example 4), whereas the non-slip film has a thickness of 0.2 mm. 1mm thick polyurethane, 1mm thick synthetic rubber, 5mm thick synthetic rubber and 3mm thick silicone rubber are attached to the outer static friction coefficient (μs1) 2.14, 2.06, 1.64, respectively. 1.23 and 1.73 (Examples 11 to 15 and Examples 16 to 20).
In addition, when the estimated value of finger pressing force; P (gf) when opening the perforation was calculated, it was 708 (Comparative Example 3) and 576 (Comparative Example 4) for the non-axially stretched polypropylene film alone. On the other hand, as a non-slip film, when a synthetic rubber with a thickness of 0.2 mm, a polyurethane with a thickness of 1 mm, a synthetic rubber with a thickness of 1 mm, a synthetic rubber with a thickness of 5 mm, and a silicon rubber with a thickness of 3 mm are attached, The finger pressing force; P (gf) was 358, 375, 498, 732, 465 in Examples 11 to 15 and 252, 264, 345, 492, and 323 in Examples 16 to 20, respectively (Table 1). reference).
That is, by sticking the non-slip film to the non-axially stretched polypropylene film, the outer static friction coefficient is increased, and as a result, the pressing force of the finger when opening the perforation is considered to be reduced (Comparative Example 3, 4, Examples 11-15, Examples 16-20).

[Sensory test]
Samples of pocket tissue corresponding to Examples 1 to 20 and Comparative Examples 1 to 4 were prepared, and sensory evaluation was performed on the ease of opening the individual packaging films of the samples. As the contents of this sample, “Erière luxury moisturizing tissue” manufactured by Daio Paper Co., Ltd. was used.
The sensory evaluation test was performed in a constant temperature and humidity room under the conditions of a temperature of 23 ° C. and a humidity of 50%, and the evaluation was performed in the following four stages.
◎; Very easy to open (It does not require force and can be opened without tearing the tissue paper inside.)
○; Easy to open (requires a little force, but can be opened without tearing the tissue paper inside)
Δ: Slightly difficult to open (requires force, but not enough to tear the tissue paper inside)
×: Difficult to open (It takes power to open, and the tissue paper inside may be torn.)
The pressing force (P (gf)) for opening the perforation is preferably 100 gf to 450 gf.
As is clear from the results shown in Table 1, if the finger pressing force (P (gf)) is 450 gf or less, the perforation of the individual wrapping film could be easily opened.
In particular, if the finger pressing force (P (gf)) was 300 gf or less, the perforation could be cut more easily.
In addition, when the pressing force (P (gf)) when opening the perforation is less than 100 gf, the timing when the manufacturer or the user does not want it (for example, during the production, when the product is transported, when stored in the bag) ) Has a problem that the perforation is cut open.

To make it easier to open the perforation of the pocket tissue individual packaging film, the perforation strength can be lowered, but if the perforation strength is simply reduced, the perforation on the line when manufacturing the pocket tissue is reduced. When the bag is broken or the pocket tissue is transported in the cardboard case, the perforation may break due to the weight underneath the cardboard case, so a certain degree of perforation strength is required. .
On the other hand, if the perforation strength is excessively increased, the inner tissue (particularly soft moisturizing tissue) may be broken when the perforation of the individual packaging film is opened.
Therefore, as in the present embodiment, a pocket slip region is provided at a portion where a finger hits when opening the perforation of the pocket tissue, thereby realizing a pocket tissue that is easy to open and that does not easily cause defective products.

As described above, according to the pocket tissue 100 of the first embodiment, the inner side surface of the perforation constituting surface portion 1a facing the tissue paper P is relatively slippery, and on the other hand, the outer side opposite to the inner side surface. The side surface is provided with two non-slip areas 2 and 2 which are relatively difficult to slip so as to sandwich the perforation M in a direction intersecting with the extending direction. The outer surface of the perforation constituting surface portion 1a of the first package 1 held by the user becomes difficult to slip, and the perforation M can be opened with a weaker force. That is, since the outer surface of the perforation constituting surface portion 1a is difficult to slip, when the perforation M is cut open, the pocket tissue 100 has two edge portions in the left-right direction (two edges on the front and rear sides). Part) It becomes difficult to bend so that they are close to each other, and even if the overlap of the tissue paper P is small only in the portion directly below the perforation M, the tissue paper P can be hardly broken. Further, it is not necessary to change the perforation M to a shape that can be easily opened, and there is no possibility of breakage during the manufacture and transportation of the pocket tissue 100.
Thus, the perforation M of the pocket tissue 100 can be cut open with a weaker force, and the tissue paper P can be prevented from being torn when the perforation M is cut open.

  In addition, the two non-slip regions 2 and 2 are configured by sticking a non-slip film 2a formed using a relatively non-slip material to the outer surface of the perforation constituting surface portion 1a. The non-slip region 2 can be formed simply by sticking the non-slip film 2 a to the outer surface of the first package 1. In addition, by forming the first package 1 using the material used for the package of the general pocket tissue 100, there is no need to use a special film or the like for manufacturing the first package 1, The cost of the pocket tissue 100 can be reduced.

  In addition, the two non-slip areas 2 and 2 are provided on the outer surface of the perforation constituting surface portion 1a so as to face each other so as to sandwich the substantially central portion in the extending direction of the perforation M. The outer surface of the perforation constituting surface portion 1a of the first package 1 can be properly held using the fingers of both hands (for example, thumbs). In particular, for example, by providing two non-slip areas 2 and 2 on the outer side surface of the perforation constituting surface portion 1a substantially parallel to the extending direction of the perforation M, the perforation structure of the first package 1 is provided. The freedom degree of the holding position by the user of the outer surface of the surface part 1a can be improved more.

  In the first embodiment, the non-slip region 2 is provided on the outer surface of the perforation constituting surface portion 1a of the first packaging body 1, but, for example, faces the perforation constituting surface portion 1a of the first packaging body 1. The non-slip region 2 may also be provided on the lower surface portion. That is, when the perforation M is cut open while holding the perforation constituting surface portion 1a with the thumbs of both hands, for example, the index finger and the middle finger are in contact with the lower surface portion of the first package 1. Therefore, by providing the non-slip region 2 on the lower surface, the index finger and the middle finger are less likely to slip, and the perforation M can be opened with a weaker force.

6 is a perspective view showing a pocket tissue 200 according to a second embodiment to which the present invention is applied, and FIG. 7 is a cross-sectional view of the pocket tissue 200 taken along line VII-VII in FIG.
The pocket tissue 200 according to the second embodiment has substantially the same configuration as the pocket tissue 100 according to the first embodiment except for the details described below, and the detailed description thereof is omitted.

  As shown in FIG.6 and FIG.7, the pocket tissue 200 of Embodiment 2 has the 2nd package body 201 of the two-layer structure which has the inner layer part 201a and the outer layer part 201b.

  The 2nd package 201 is formed in the substantially rectangular parallelepiped shape similarly to the 1st package 1 of Embodiment 1, and the perforation structure surface part 1a is comprised by the upper surface of the said 2nd package 201. FIG. As in the first embodiment, the perforation constituting surface portion 1a has a linear perforation M extending along the left-right direction (longitudinal direction) of the second package 201 at a substantially central portion in the front-rear direction. Is provided.

The inner layer portion 201a has substantially the same configuration as the first package 1 of the first embodiment, and the tissue paper P is accommodated inside the inner layer portion 201a. Further, the entire inner side surface of the inner layer portion 201a is relatively slippery like the first package 1 of the first embodiment.
Note that it is only necessary that at least the inner side surface corresponding to the perforation constituting surface portion 1a of the inner layer portion 201a is relatively slippery, not the entire inner side surface of the inner layer portion 201a.

  The outer layer part 201b is stuck on the outer side of the inner layer part 201a. Further, the outer layer portion 201b has an outer surface that is relatively difficult to slide relative to the inner surface of the inner layer portion 201a. Specifically, the outer layer portion 201b is formed using a relatively non-slip material such as a synthetic rubber, a polyurethane resin, or a non-axially stretched polypropylene film having non-slip properties. For example, the coefficient of static friction between the outer surface of the outer layer portion 201b and the finger pressing the outer layer portion 201b to open the perforation M is preferably 1.2 or more, and more preferably 1.5 or more. .

In addition, the non-axially stretched polypropylene film having slipperiness is formed by blending a known slip agent with the non-axially stretched film. Examples of the slip agent include hydrocarbon-based slip agents such as liquid paraffin and polyethylene wax, metal soap-based slip agents such as calcium stearate and magnesium stearate, oleic acid amide, erucic acid amide, behenic acid amide, and ethylenebisolein. Amide slip agents such as acid amides and ethylenebiserucic acid amides are listed, but are not limited to these examples, and can be arbitrarily changed as appropriate.
Examples of the method of blending the slip agent include a master batch method and a pellet blend method immediately before film formation. However, the method is not limited to these examples, and can be arbitrarily changed as appropriate.

Then, two non-slip areas 2 and 2 which are relatively hard to slip are configured by two areas before and after sandwiching the perforation M of the perforation constituting surface part 1a of the outer layer part 201b in the direction intersecting with the extending direction. ing.
Note that it is only necessary that at least the outer surface corresponding to the perforation constituting surface portion 1a of the outer layer portion 201b is relatively less slippery than the entire outer surface of the outer layer portion 201b.

Even in such a configuration, according to the pocket tissue 200 of the second embodiment, as in the first embodiment, the perforation constituting surface portion of the second package 201 held by the user when the perforation M is opened. The outer surface of 1a becomes difficult to slip, and the perforation M can be opened with a weaker force, and the tissue paper P can be prevented from being torn when the perforation M is opened.
Further, since the two non-slip areas 2 and 2 are formed using a relatively non-slip material, the non-slip film 2a is attached to the outer surface of the package as in the first embodiment. The work to do becomes unnecessary. In particular, since the entire outer surface of the outer layer portion 201b of the second package 201 is relatively less likely to slip, for example, when the perforation M is cut open, the two non-slip areas 2 and 2 that are in contact with the thumbs of both hands can be easily obtained. In addition, the lower surface portion of the second package 201 that comes into contact with the index finger or the middle finger is difficult to slide, and the perforation M can be opened with a weaker force.

The present invention is not limited to the first and second embodiments, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, as the perforation M, the one formed so as to extend in the left-right direction at a substantially central portion in the front-rear direction of the perforation configuration surface portion 1a is illustrated, but the position, shape, and the like of the perforation M are examples. It is not restricted to this, It can change arbitrarily arbitrarily. Further, the arrangement and the like of the two non-slip areas 2 and 2 can be arbitrarily changed as appropriate according to the position and shape of the perforation M.

  Further, in the first and second embodiments, the pocket tissue 100, 200 is illustrated as an example of the sanitary thin paper product. However, the present invention is not limited to this example, and the sanitary thin paper is provided inside the package. If it is accommodated, it can be arbitrarily changed as appropriate.
