Description

The present invention relates to a seat storage box.

A sheet such as tissue paper is stored in a box made of thick paper or the like, and is pulled out from an outlet opening on the top surface of the box for use. In the conventional sheet storage box, a resin film (so-called window-pasting film) is provided at the outlet, and the sheet is pulled out through a slit formed in the film (for example, Japanese Patent No. 4142238). See publication).

In addition, _{as a measure against global warming associated with CO 2} emissions in recent years, there is a movement to curb the use of plastics from the viewpoint of reducing the use of fossil fuels and curbing marine pollution such as microplastics. On the other hand, a sheet storage box (so-called filmless carton) that does not use a resin film has been conventionally known (see, for example, Japanese Patent No. 6554284).

Japanese Patent No. 4142238 Japanese Patent No. 6554284

However, in a sheet storage box that does not use a resin film, the sheet to be pulled out may be caught on the peripheral edge of the outlet, making it difficult to pull out the sheet. In addition, the sheet to be pulled out may rub against the peripheral edge of the outlet, causing an unpleasant noise.

An object of the present invention is to provide a sheet storage box capable of smoothly pulling out a sheet without using a resin film.

A first aspect of the present invention is a sheet storage having a box body for accommodating a plurality of laminated sheets and an outlet opening on the top surface of the box body and extending in the longitudinal direction of the top surface. A box, the first flap is formed on the periphery of the outlet and has a pair of first flaps facing each other in the lateral direction of the top surface, and the first flap is a split flap divided at the center in the longitudinal direction. The split flaps provide a seat storage box that is formed so as to be tiltable upward with respect to the top surface.

In the first aspect, a pair of first flaps facing each other in the lateral direction of the top surface of the box body can incline upward with respect to the top surface of the divided flaps divided at the center of the top surface of the box body in the longitudinal direction. By forming in, each split flap can be tilted upward. Since each of the divided flaps inclined in this way makes smooth contact with the sheet to be pulled out, the peripheral edge of the outlet is less likely to become a resistance to the sheet to be pulled out. Further, the force applied to the peripheral edge of the outlet when the sheet is pulled out is distributed to each split flap.

As a result, in the first aspect, the sheet to be pulled out is less likely to be caught on the peripheral edge of the outlet, and the sheet can be easily pulled out.

As shown in FIGS. 1 to 3, the seat storage box 100 according to the present embodiment is composed of a box body B formed in a substantially rectangular parallelepiped shape (including a cube). The box body B has a top surface 10, a bottom surface 20, a pair of side surfaces 30, and a pair of end surfaces 40. The top surface 10 and the bottom surface 20 face each other in the height direction (Z direction), the pair of side surfaces 30 face each other in the lateral direction (Y direction), and the pair of end faces 40 face each other in the lateral direction (Y direction). The end faces 41 and 42 face each other in the longitudinal direction (X direction).

The material of the sheet storage box 100 is not limited, and examples thereof include coated cardboard made from virgin pulp, used paper pulp, and the like.

The dimensions of the box body B constituting the sheet storage box 100 are not limited, and can be determined by the amount and dimensions of the sheets S to be stored. For example, the length of the box body B in the longitudinal direction (X direction) can be 100 to 250 mm, preferably 200 to 250 mm. The length in the lateral direction (depth) can be 100 to 150 mm, preferably 100 to 130 mm. Further, the height in the height direction (Z direction) can be 30 to 150 mm, preferably 40 to 80 mm.

The basis weight of the box body B is not limited, but is preferably 250 to 450 g / m ² , and more preferably 300 to 400 g / m ² from the viewpoint of ensuring sufficient strength to withstand use. In this specification, the basis weight is measured according to the basis weight measuring method of JIS P 8124 (1998).

A plurality of laminated sheets S are stored in the box body B constituting the sheet storage box 100. In the present embodiment, as a laminated body of the sheets S (hereinafter referred to as a sheet laminated body), a plurality of thin paper sheets (tissue papers) are housed in the box body B so that the stacking direction is the height direction (Z direction). .. The sheet S is not limited to tissue paper, and can accommodate articles such as kitchen paper, toilet paper, paper towels, baby or long-term care disposable diapers, and sanitary napkins.

From the viewpoint of pulling out one set of laminated sheets S, the sheets S are preferably one in which each sheet S is alternately laminated in a folded state (so-called pop-up type sheet laminate). Further, the form of the sheet laminated body is not limited to the one that can be pulled out in a pop-up manner, and may be one in which a plurality of sheets S are simply laminated, or one in which each sheet S is laminated in a folded state.

The dimensions of the sheet S housed in the sheet storage box 100 are, for example, in the case of tissue paper, the dimensions of the upper surface and the bottom surface are 60 to 130 mm × 150 to 250 mm, and the height is 20 to 110 mm. The number of plies is preferably 1 ply or more, and more preferably 2 plies. The basis weight per ply is preferably 9.0 to 25.0 g / m ² , and more preferably 10.0 to 16.0 g / m ² . The paper thickness is 100 to 250 μm for two plies, and more preferably 120 to 200 μm.

For the paper thickness, after sufficiently adjusting the humidity of the test piece under the conditions of JIS P 8111 (1998), use the dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Seisakusho) under the same conditions. Therefore, it can be measured in a 2-ply state. Specifically, make sure that there is no dust or dust between the plunger and the measuring table, and then install the plunger on the measuring table. After that, move the memory of the dial thickness gauge to set the zero point. Then, raise the plunger, place the sample on the test table, 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 about 10 mm hits the paper plane perpendicularly. The load at the time of measuring the paper thickness is about 70 gf. The paper thickness is an average value obtained by performing the measurement 10 times.

The sheet storage box 100 has an outlet 50 that opens to the top surface 10 of the box body B. The outlet 50 has a shape that allows the sheet S housed in the box body B to be pulled out from the top surface 10 side. The outlet 50 has a contour shape extending in the longitudinal direction (X direction) of the box body B. Specifically, it constitutes a substantially rectangular or substantially elliptical opening formed in the center 10a of the top surface 10 in the lateral direction (Y direction) and in the longitudinal direction along the X direction.

In the present embodiment, when the sheet storage box 100 is used, the sheet S housed in the box body B is taken out to the outside through the take-out port 50 (see FIGS. 3 to 5). The length of the outlet 50 in the longitudinal direction (X direction) and the width in the lateral direction (Y direction) can be appropriately determined based on the dimensions of the sheet S and the like. Further, in the present embodiment, the outlet 50 is formed in a substantially rectangular shape or a substantially elliptical shape along the longitudinal direction (X direction) at the center 10a of the top surface 10 of the seat storage box 100 in the lateral direction (Y direction). However, the present invention is not limited to this, and other shapes may be used as long as the sheet S can be taken out.

Before use, the sheet storage box 100 has a lid 80 that covers the outlet 50 connected to the top surface 10 via a breaking cut line 81. At the time of use, the lid 80 is cut off along the breaking cut line 81 to form an outlet 50 that opens to the top surface 10. As a result, the sheet S in the box body B can be taken out upward from the outlet 50. The breaking cut line 81 indicates a cut line formed of a perforation or the like for separating the lid portion 80 during use (see FIGS. 1 and 2).

In the sheet storage box 100, the lid 80 covering the outlet 50 is connected to the top surface via the breaking cut line 81 in this way, so that the outlet 50 can be closed before the sheet storage box 100 is used. it can. Further, when the sheet storage box 100 is used, the outlet 50 can be opened by opening the breaking cut line 81 of the lid portion 80 (see FIGS. 1 to 3).

The seat storage box 100 according to the present embodiment has a pair of first flaps 60 facing each other in the lateral direction (Y direction) of the top surface 10. The pair of first flaps 60 are formed on the peripheral edge 50a of the outlet 50. The pair of first flaps 60 is composed of a first flap 61 formed on the side surface 31 side of the outlet 50 and a first flap 62 formed on the side surface 32 side of the outlet 50 (FIG. 1, FIG. 1, 2).

The first flap 61 is further composed of divided flaps 63 and 65. The divided flaps 63 and 65 have a configuration in which the first flap 61 is divided at the center 10b in the longitudinal direction (X direction) of the top surface 10. Further, the first flap 62 is composed of the divided flaps 64 and 66. The split flaps 64 and 66 are configured to be split at the center 10b in the longitudinal direction (X direction).

The split flaps 63 and 65 constituting the first flap 61 are further formed so as to be inclined upward with respect to the top surface 10. Further, the divided flaps 64 and 66 constituting the first flap 62 are also formed so as to be inclined upward with respect to the top surface 10. Here, inclining upward with respect to the top surface means that the split flap is formed on the peripheral edge 50a of the outlet 50 in a state where the split flap rises diagonally with respect to the top surface (see FIGS. 3 to 5). .. Further, tiltable means that the split flap can change from a non-tilted state to a tilted state (see FIGS. 1 to 5).

The angle at which the divided flaps 63, 64, 65, and 66 are tilted (hereinafter referred to as the tilt angle) is not particularly limited, but is preferably an acute angle with respect to the opening surface of the outlet 50. Specifically, the inclination angles of the divided flaps 63, 64, 65, 66 are 10 ° or more and 80 ° or less, preferably 20 ° or more and 70 ° or less, and more preferably with respect to the opening surface of the outlet 50. It is preferably 30 ° or more and 60 ° or less. The inclination angles of the divided flaps 63, 64, 65, and 66 may be the same angle or different angles.

In the present embodiment, the first flaps 61 and 62 are each divided into two divided flaps (four in total), but the number of divided flaps is not limited. For example, at least one of the first flaps 61 and 62 may be disassembled into three or more split flaps. Further, in the present embodiment, the split flap is tilted to take out the sheet (see FIGS. 3 to 5), but the sheet can be taken out without tilting the split flap.

In the present embodiment, as described above, the pair of first flaps 60 (first flaps 61, 62) formed on the peripheral edge 50a of the outlet 50 and facing the lateral direction (Y direction) of the top surface 10 are heavenly. It is composed of split flaps 63 and 65 and split flaps 64 and 66, which are divided at the center 10b in the longitudinal direction (X direction) of the surface 10, respectively. The divided flaps 63, 64, 65, and 66 are formed so as to be inclined upward with respect to the top surface 10.

As a result, each of the split flaps 63, 64, 65, 66 can be tilted upward, and the tilted split flaps 63, 64, 65, 66 smoothly contact the sheet S drawn from the outlet 50. can do. Therefore, the peripheral edge 50a of the outlet 50 is unlikely to become a resistance to the drawn sheet S (see FIGS. 3 to 5).

In the present embodiment, the force applied to the peripheral edge 50a of the outlet 50 when the sheet S is pulled out is absorbed by the inclined split flaps 63, 64, 65, 66. Further, the force applied to the peripheral edge 50a of the outlet 50 when the sheet S is pulled out is distributed to the divided flaps 63, 64, 65, 66.

As a result, in the present embodiment, the sheet S to be pulled out is less likely to be caught on the peripheral edge 50a of the outlet 50, and the sheet S can be easily pulled out. Further, even if the drawn sheet S rubs against the peripheral edge 50a of the outlet 50, an unpleasant sound is unlikely to be generated. Therefore, according to the present embodiment, the sheet S can be smoothly pulled out without using a resin film (so-called window-pasting film) (even if it is a so-called filmless carton) (see FIGS. 3 to 5). ..

In the present embodiment, the first flap 61 is cut out from the portion 51 of the center 10b of the top surface 10. Further, in the first flap 62, a portion 52 of the center 10b of the top surface 10 is cut out. Specifically, the portions 51 and 52 of the center 10b of the top surface 10 of the first flaps 61 and 62 are open as a part of the outlet 50 without the flaps (see FIGS. 1 and 2). ..

In the present embodiment, the first flaps 61 and 62 are cut out at the center 10b in the longitudinal direction (X direction) of the top surface 10, so that the divided flaps 63, 64, 65 and 66 constituting the first flaps 61 and 62 are formed. Is easy to form. Further, recesses 67 and 68 are formed in the notched portions of the first flaps 61 and 62, and a finger can be inserted into the box body B from the recesses 67 and 68, so that the sheet S can be easily pulled out. (See FIGS. 2 to 4).

In the present embodiment, in the first flap 61, the portion 51 of the center 10b in the longitudinal direction (X direction) of the top surface 10 is directed toward the outside (the end surface 41 side) of the outlet 50 in the lateral direction (Y direction). It is curved. Further, in the first flap 62, the portion 52 of the center 10b in the longitudinal direction (X direction) of the top surface 10 is curved toward the outside (the end surface 42 side) of the outlet 50 in the lateral direction (Y direction). There is. Here, bending means that a part of the outlet 50 expands convexly toward the outside of the outlet 50 in the lateral direction (Y direction) of the top surface 10 (see FIGS. 1 to 3).

In the present embodiment, the first flaps 61 and 62 are curved toward the outside of the outlet 50 in the lateral direction (Y direction) of the top surface 10 at the center 10b in the longitudinal direction (X direction) of the top surface 10. Therefore, the opening portions (recesses 67, 68) of the outlet 50 can be expanded in the lateral direction (Y direction) of the top surface 10. This makes it easier to form the split flaps 63, 64, 65, 66 constituting the first flaps 61, 62. Further, since it is easy to insert a finger into the opening portion (recessed portion 67, 68) of the outlet 50 extending in the lateral direction (Y direction) at the center 10b of the top surface 10 in the longitudinal direction (X direction), the sheet S can be pulled out. It is even easier (see FIGS. 1 to 3).

In the sheet storage box 100, the portion 51 of the center 10b of the first flap 61 constitutes the opening end 81a of the lid portion 80. Further, the portion 52 of the center 10b of the first flap 62 constitutes the opening end 81b of the lid portion 80. The opening ends 81a and 81b form a part of the breaking cut line 81 of the lid portion 80, and by hooking a finger or the like on the opening ends 81a and 81b, a part of the breaking cut line 81 is opened and the outlet 50 is opened. Can be opened (see FIGS. 1 to 3).

In the present embodiment, the portions 51 and 52 of the central 10b of the first flaps 61 and 62 form the opening ends 81a and 81b of the lid 80, so that the opening 81a of the lid 80 is taken out in the lateral direction of the outlet 50. It can be curved toward the outside (Y direction). As a result, when opening the outlet 50, it becomes easier to put a finger on the opening ends 81a and 81b of the lid 80, and the outlet expands in the lateral direction (Y direction) at the center 10b of the top surface 10 (X direction). The lid 80 can be cleaved by using the openings (recesses 67, 68) of 50 as a trigger. Therefore, in the present embodiment, the outlet 50 can be easily opened (see FIGS. 1 to 3).

In the seat storage box 100, the base ends 63a, 64a, 65a, 66a of the divided flaps 63, 64, 65, 66 are linear. In the present specification, the proximal end refers to an end portion connected to the peripheral edge 50a of the outlet as a starting point at which the flap is inclined or rotated (see FIGS. 1 to 5).

In the present embodiment, by making the base ends 63a, 64a, 65a, 66a of the split flaps 63, 64, 65, 66 into such a linear shape, the split flaps 63, 64, 65, 66 become the base ends 63a, 64a. , 65a, 66a as an axis, and it becomes easy to rotate. Therefore, the split flaps 63, 64, 65, 66 are likely to be tilted upward when the sheet S comes into contact with each other, and the split flaps 63, 64, 65, 66 are formed on the peripheral edge 50a of the outlet 50 when the sheet S is pulled out. It is possible to absorb more of the force applied to. Therefore, according to the present embodiment, the sheet S can be pulled out more smoothly (see FIGS. 3 to 5).

Further, the base ends 63a, 64a, 65a, 66a of the split flaps 63, 64, 65, 66 are formed by valley fold fold lines F (see FIGS. 2 to 5).

The dimension in the lateral direction (Y direction) of 54 was set to about 25 mm.

<Sheet (tissue paper)>
^{Sheet S is a tissue paper (basis weight: 10.7 g / m 2} , paper thickness: 110 μm, number of plies: 2 plies, number of pairs: 150 pairs) that are alternately folded and laminated so that one pair can be pulled out in a pop-up manner. (300 sheets), dimensions: bulk (height) of about 40 mm, vertical width of about 197 mm, width of about 207 mm were used. In addition, the stacking direction of the sheet S is the height direction (Z direction) of the sheet storage box 100. It was housed in the box body B as described above (see FIGS. 1 and 9).

[Removability]
The initial reproducibility of the sheet storage box 100 was evaluated. In the evaluation of takeability, a set of sheets S was picked by inserting the take-out port 50 thumb and index finger formed on the top surface 10 from the laminated body of the sheets S housed in the box body B of the sheet storage box 100. I confirmed the ease of picking when. The ease of removal was evaluated according to the following criteria. The evaluation criteria for the ease of removal were good when the takeability was 3 or more (sheet S was easy to take out), and poor when it was less than 3 (difficult to take out the sheet S).
5: The first pair pinches without the finger touching the outlet 4: The finger touches the outlet slightly but the first pair pinches 3: The finger touches the outlet but the first pair pinches 2: The first pair is difficult to pinch when your finger touches the outlet 1: The first pair is not pinched

[Drawer resistance value]
The drawer resistance value of the seat storage box 100 was evaluated. In the evaluation of the withdrawal resistance value, the test body (sheet storage box 100) was placed on a flat mounting surface, and the first set of tissue paper (sheet S) was pulled out from the outlet 5 of the box body B by about 40 mm and pulled out. The upper tip of the sheet S (center of the end of the sheet S) was sandwiched between double clips ("CP-103" manufactured by PLUS Corporation, the size of the sandwiching portion is about 32 mm). Hook the hook of the push-pull gauge (Digital Force Gauge Z2-20N, manufactured by Imada Co., Ltd.) on one side of the handle of the double clip, and take 0.4 to 0.6 seconds at a constant speed to accommodate the container. The resistance force (unit: gf) when the sheet S was pulled out in the direction perpendicular to the upper surface was measured. The evaluation standard of the withdrawal resistance value is good when the resistance force when the fifth set of the sheet S is pulled out is 130 gf or less (the sheet S is easy to take out), and is not good when it exceeds 130 gf (the sheet S is easy to take out). Sheet S is difficult to take out).

[Sound when taking out]
The sound at the time of taking out the sheet S of the sheet storage box 100 was evaluated, and the sound range felt to be jarring (or unpleasant) was confirmed. For sound evaluation, a wooden stand was installed in the center of a semi-anechoic chamber (room temperature 23.8 ° C, humidity 60% rh, width 75 cm x depth 75 cm x height 75 cm), and a test piece (test piece (in the center of the stand). A seat storage box 100) was installed. The microphone was installed at a height of 70 cm from the table at an oblique angle of 45 degrees upward where the take-out sound was generated. Grasp the center of the edge of the tissue paper with the middle finger, index finger, and thumb of the right hand, and record the sound (dB) of continuously taking out the 1st to 15th sets vertically at a speed of 1 second per set. .. The evaluation criteria for the sound at the time of extraction are good (not unpleasant sound) when the sound (dB) at 4000 Hz is 50 dB or less, and not good (not unpleasant sound) when it exceeds 50 dB. I made it.

[loudness]
The loudness at the time of taking out the sheet S of the sheet storage box 100 was evaluated. For the evaluation of loudness, the loudness index (loudness perceived by a person) was calculated from the above-mentioned sound at the time of extraction. The loudness index is expressed in units of sound, and a loudness of 1000 Hz with a sound pressure level of 40 dB is defined as 1 sound. For example, if the loudness felt by a person is doubled, it will be 2Sone, and if it is halved, it will be 0.5son. In addition, the evaluation standard of loudness was considered to be good (does not feel loud) when it is 8Sone or less, and not good (feels loud) when it exceeds 8Sone.

Hereinafter, Examples and Comparative Examples will be described.

[Comparative Example 3]
A commercially available sheet storage box (seat storage box disclosed in Patent Document 2) was evaluated in the same manner as in Example 1. The results are shown in Table 1.

From Table 1, a pair of first flaps 60 (first flaps 61, 62) formed on the peripheral edge 50a of the outlet 50 and facing the lateral direction (Y direction) of the top surface 10 are formed in the longitudinal direction of the top surface 10 (1st flaps 61, 62). The seat storage box 100 composed of the divided flaps 63, 64, 65, 66 which are divided at the center 10b in the X direction and can be inclined upward with respect to the top surface 10 has good take-out property and pull-out resistance value. (Examples 1 to 3).

Further, in the first flaps 61 and 62, the portions 51 and 52 of the center 10b in the longitudinal direction (X direction) are cut out so as to be curved toward the outside of the outlet 50 in the lateral direction (Y direction), and the split flaps are divided. 63, 64, 65, 66 are configured, and the base ends 63a, 64a, 65a, 66a of the split flaps 63, 64, 65, 66 are formed linearly by the valley fold fold streaks F, and the split flaps 63, 64, 65 and 66 are formed in a tapered shape toward the inside of the outlet 50, and the corner portions 67a, 67b, 68a and 68b of the tips 63b, 64b, 65b and 66b near the center 10b are formed in a curved shape. A pair of second flaps 70 (second flaps 71, 72) formed at both ends 53, 54 and facing the longitudinal direction (X direction) can be inclined upward with respect to the top surface 10, and the base ends 71a, 72a are valleys. The second flaps 71 and 72 are formed in a linear shape by the folding streaks F, the second flaps 71 and 72 are formed in a tapered shape toward the inside of the outlet 50, and the tips 71b and 72b are taken in the longitudinal direction (X direction) of the top surface 10. The seat storage box 100 formed so as to be curved toward the outside of the outlet 50 had good sound and loudness at the time of taking out (Example 1).

On the other hand, in the configuration in which the split flap was not provided, at least one of the take-out property, the pull-out resistance value, the sound at the time of take-out, and the loudness was not good (Comparative Examples 1 to 3).

From these results, a pair of first flaps formed on the periphery of the outlet extending in the longitudinal direction of the top surface of the box body and facing the lateral direction of the top surface of the box body are divided at the center in the longitudinal direction. It can be seen that the seat storage box composed of the split flaps that can be inclined upward with respect to the surface can smoothly pull out the seat without using a resin film.
