[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to Figures 1 to 7. However, the present invention is not limited to this embodiment.

[0017] The article contained in the package is a laminate of sanitary thin paper such as tissue paper, hand towels, kitchen towels, etc. The sanitary thin paper laminate is made by folding and storing sanitary thin paper so that it can be removed in a pop-up style. The tissue paper according to the present invention also includes so-called wet type tissue paper to which a moisturizing agent or the like is added. In the following embodiment (see Figures 1 to 7), a case will be described in which the sanitary thin paper is tissue paper and the laminate is compressed and packaged as an example.

[0018] In this specification, the terms "top surface" and "bottom surface" refer to the surfaces of the components themselves. However, these terms are used merely for convenience and do not, of course, define absolute positions in the direction of gravity. The same applies to terms such as "upper" and "lower."

[0019] In addition, in the description of this specification, the term "rectangle" not only includes rectangular shapes but also square shapes, and also includes approximate rectangular shapes and approximate square shapes.

[0020] <Configuration of tissue paper stack compressed and wrapped by wrapping device> Figure 1 is an overall oblique view of a compressed body of a sanitary thin paper stack (hereinafter referred to as a "compressed package of a sanitary thin paper stack" or simply "package") 1 according to one embodiment of the present invention, and Figure 2 is a front plan view of the package containing a sanitary thin paper stack 11p, with Figure 2(a) showing the package 1p for the sanitary thin paper stack before compression and Figure 2(b) showing the compressed package 1 for the sanitary thin paper stack shown in Figure 1.

[0021] The sanitary tissue paper stack 11p is, for example, a stack of tissue paper equivalent to five tissue cartons, and is contained in a packaging member (a gusset bag in this embodiment) 12 with a sealed bottom. It is then compressed and packaged as a sanitary tissue paper stack 1 as shown in Figures 1 and 2(b) by a packaging device 2, which will be described later. The tissue paper to be compressed and packaged in this invention is not limited to five tissue cartons, but may be equivalent to one or more boxes other than five. Furthermore, in this invention, multiple soft pack tissues may be stacked and packaged. In this case, holes may be provided in the exterior packaging to release air from the soft pack tissues (holes to prevent each soft pack tissue from inhibiting compression).

[0022] As shown in Figures 1, 2(a), and 2(b), the packaging body 1 according to this embodiment includes a sanitary thin paper stack 11p and a flexible packaging member 12 having a storage space capable of storing the sanitary thin paper stack 11p, and the sanitary thin paper stack 11p is stored in a compressed state within the storage space of the packaging member 12, and the density of the sanitary thin paper stack 11p in the compressed state is 0.25 g / cm 3 More than 0.30g / cm 3 The following is the result.

[0023] With this configuration, the stack 11p of sanitary tissue paper stored therein is compressed so that it can be restored to its original shape and used again, which in turn reduces material costs, logistics costs, and storage space.

[0024] In this embodiment, as shown in Figures 2(a) and 2(b) (and Figures 3(a), 3(d), 4(a), and 4(b) described below), the sanitary thin paper stack 11p is compressed in the stacking direction of the sanitary thin paper.

[0025] In this embodiment, the sanitary thin paper stack 11p is compressed to 60% or less of its length in the compression direction compared to its initial state before compression and is then stored. Details will be described later.

[0026] In this embodiment, the packaging member 12 is airtightly sealed with the storage space decompressed by a packaging device 2 (particularly a compressor 23, a deaerator 25, and a sealing means 26) described below.

[0027] In this embodiment, the inner peripheral surface of the packaging member 12 can define the outer peripheral shape of the stack 11 of sanitary thin paper in a compressed state.

[0028] In this embodiment, after opening the packaging member 12, the thickness of the sanitary thin paper stack 11p becomes more than 1 time and approximately 1.5 times or less. In other words, after opening the packaging member 12, the shape of the compressed stack 11 returns (partially).

[0029] In this embodiment, the packaging member 12 includes a resin film and has a thickness of 20 μm to 100 μm.

[0030] The package of the present invention may be formed by stacking a plurality of individually wrapped tissues.

[0031] <Packaging equipment configuration> Fig. 3 is a plan view of the packaging device 2 that produces the package 1 according to this embodiment, with Fig. 3(a) being a front view, Fig. 3(b) being a top view, Fig. 3(c) being a bottom view, and Fig. 3(d) being a front view after the container 1p of the target article, a laminate of sanitary thin paper, has been compressed to the second predetermined position P2. Fig. 4 is a cross-sectional view seen from the side of the packaging device 2 that produces the package 1 according to this embodiment, with Fig. 4(a) being a cross-sectional view taken along the line IVa-IVa in Fig. 3(a) showing the state before compression, and Fig. 4(b) being a cross-sectional view taken along the line IVb-IVb in Fig. 3(d) showing the state after compression. FIG. 5 is a plan view of the components of the packaging device 2 that produces the package 1 according to this embodiment. FIG. 5(a) is a top view of the box 22, FIG. 5(b) is a cross-sectional view along the Vb-Vb direction of FIG. 5(a), FIG. 5(c) is a cross-sectional view along the Vc-Vc direction of FIG. 5(a), and FIG. 5(d) is a top view of the upper plate 24. FIG. 6 is a diagram illustrating the process of degassing and sealing the compressed sanitary tissue paper stack 1p using a degasser 25 and sealing means 26 included in the packaging device 2 that produces the package 1 according to this embodiment. For ease of explanation, the lever 231 of the hydraulic jack 23 is omitted from FIG. 4. Furthermore, FIG. 6 shows only the components of the packaging device 2 that are necessary to focus on the degassing and sealing processes, and omits the frame 21, box 22, and hydraulic jack 23.

[0032] The packaging device (compression processor) 2 that produces the packaging body 1 of this embodiment is a device that packages and compresses a stack 11p of sanitary thin paper, as shown in Figures 3 to 6, and is equipped with a regulating section 22 that can regulate displacement in a predetermined direction of the stack 11p when it is contained in a packaging member 12 and placed at a first predetermined position P1, a compressor 23 that compresses the stack when placed at the first predetermined position P1 to a second predetermined position P2, a deaerator 25 that deaerates the packaging member 12 after compression, and a sealing means 26 that seals the opening 14 of the evacuated packaging member 12.

[0033] This configuration allows the sanitary thin paper stack 11p to be compressed and packaged simply and easily, thereby reducing material costs, logistics costs, and storage space.

[0034] The packaging device 2 that produces the package 1 according to this embodiment includes a platform on which the compressor 23 and the restricting unit 22 are placed, and a frame 21 that supports and fixes the upper plate 24 described below. The support plate on which the restricting unit 22 is installed and supported is fixed to the ram of the compressor 23, and is movable in the vertical direction so as to be raised and lowered by the compressor 23.

[0035] The restricting portion 22 is capable of receiving a tissue stack container 1p therein. In this embodiment, the restricting portion 22 has a surrounding surface that surrounds the outer periphery of the tissue stack 11p in a direction perpendicular to the compression direction. The surrounding surface of the restricting portion 22 restricts displacement of the stack 11p in a direction perpendicular to the compression direction. By arranging the surrounding portion so that it abuts or is close to the stack 11p along the entire periphery, the space defined by the restricting portion 22 can be formed so that the bottom surface of the restricting portion 22 abuts the bottom surface of the stack 11p and is close to two pairs of side surfaces of the stack 11p without any gaps. In this embodiment, the restricting portion 22 is a box-shaped body, as shown in FIGS. 3 to 5. The box-shaped body 22 is removable from the packaging device 2. In this embodiment, the first predetermined position P1 is the bottom surface of the restricting portion 22. The second predetermined position P2 is a position set based on the scale provided on the restricting portion 22, and in this embodiment, it is a position corresponding to the open end of the box 22. In the process of placing the tissue stack container 1p at the first predetermined position P1 of the restricting portion 22, the restricting portion 22 can restrict displacement of the tissue stack 11p in a predetermined direction. By arranging the surrounding portion so that it abuts or is close to the stack 11p around the entire periphery, it is possible to restrict displacement of the stack in a direction perpendicular to the compression direction. In this way, it is possible to prevent the stack from shifting position during compression. In the present invention, the restricting portion 22 may be formed in a shape and size that leaves a gap between it and the stack.

[0036] The compressor 23 is configured to lift the box 22 via a support plate that supports the underside of the box. In this embodiment, the compressor 23 is a hydraulic jack. By pressing (pumping) the lever 231, the ram rises, lifting the tissue stack 11p and sandwiching it between the upper plate 24, compressing the target object in the stacking direction of the tissue stack 11p. A release valve (not shown) releases the hydraulic pressure to lower the target object, allowing adjustment of the compression of the target object. The present invention may include multiple hydraulic jacks (or cylinders). Furthermore, the present invention is not limited to hydraulic jacks; mechanical jacks (screw jacks, rack-driven jacks), air jacks, etc. may also be used, or a compressor configured with multiple of these may be used. The compressor 23 compresses the sanitary tissue stack 11p so that its height dimension H2 after compression is 60% or less of its height dimension H1 before compression (see Figures 2(a) and 2(b)). This compression can be continued until the dimension H2 is about 50%, and after the tissue paper stack is removed from the compressed packaging, the tissue returns to its original shape to some extent due to its restoring force, and the texture does not change much compared to the tissue paper stack before compression, maintaining the feel it had when used (see Table 1 and its explanation below).

[0037] As shown in FIGS. 3(b) and 5(d), the upper plate 24 has an opening 241 in the center, and the upper portion of the packaging member 12 of the tissue stack container 1p is passed through the opening 241, and compression by the compressor 23 is performed. The upper plate 24 is sized to cover substantially the entire upper surface of the container 1p. The present invention is not limited to this, and the upper plate may be smaller than the upper surface of the container. In this embodiment, the upper plate 24 is compressed to a position where it abuts the upper edge of the restricting portion 22 (in this case, the upper plate 24 is configured not to enter the restricting portion 22), and then the degassing process begins. Alternatively, the upper plate 24 may be configured to enter the internal space of the restricting portion 22, in which case the upper surface of the stack 11p can be compressed below the upper end of the restricting portion 22. The compression end position may also be determined by a visible scale, such as a groove carved into the inner peripheral surface of the surrounding portion. After (or during) the compression, the upper part of the packaging member 12 is used by a deaerator 25 and a sealing means 26, which will be described later, to deaerate the interior of the packaging member 12 and seal the opening 14 of the packaging member 12. By deaerating and sealing during compression, it becomes possible to hermetically seal the packaging member 12 with the storage space containing the tissue paper stack reduced in pressure.

[0038] In this embodiment, the deaerator 25 and the sealing means 26 are integrated. However, in the present invention, they may be separate. Known deaerators and sealers may be used for the deaerator 25 and the sealing means 26. In this embodiment, the deaerator 25 and the sealing means 26 can be installed on a plate (not shown) connected to the upper part of the frame 21. The deaerator 25 and the sealing means 26 are configured to open and close vertically. The deaerator 25 has an air intake nozzle (not shown), which is inserted into the opening 14 of the packaging member 12 to deaerate. After deaerating, the sealing means 26 seals the opening 14 of the packaging member 12, thereby forming a seal portion 13 in the packaging member 12 and sealing it. While the seal portions 13 shown in FIGS. 1 and 2(b) are two linear portions, this is not a limitation in the present invention; one or three or more portions may be used, and any shape may be used as long as the sealing function is achieved.

[0039] In this embodiment, the package 1 is produced by the packaging device 2, but the present invention is not limited to this, and the package 1 may be produced using a compressor, deaerator, or sealing means other than the packaging device 2.

[0040] <Packaging material composition> In the present invention, the material and thickness of the packaging member 12 can be appropriately selected as follows.

[0041] The packaging member 12 can be made of a resin material, a biodegradable material (biodegradable plastic such as polylactic acid), a biomass material (biomass plastic), or a film made of a combination of these.

[0042] Examples of resins constituting the film forming the packaging member 12 include polyolefin resins, polyester resins, polyamide resins, polyether resins, acrylic resins, and natural polymer compounds (cellulose acetate, etc.). These can be used alone or in combination of two or more. Examples of polyolefin resins include polyethylene (PE), polypropylene (PP), and ethylene-vinyl acetate copolymer (EVA). Examples of polyester resins include polyethylene terephthalate (PET) and polyethylene naphthalate (PEN).

[0043] Furthermore, polystyrene (PS), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polyamide (PA), etc. may also be used as the resin for the film that forms the packaging member 12. Among these, polyethylene, polypropylene, etc. are preferred because they are flexible and easy to handle, have high heat-sealing properties, and are inexpensive.

[0044] It is also preferable to select a resin with high gas barrier properties, but even if a resin with relatively low gas barrier properties is selected, the gas blocking effect can be improved by increasing the film thickness. For example, in the case of polyethylene, a film thickness of less than 40 μm is susceptible to adverse effects due to gas permeation, and the degassed state may be lost, so it is desirable to make the film 40 μm or more.

[0045] In contrast, in the case of a material with high gas barrier properties such as polypropylene, even a thickness of 40 μm can block gas, so the thickness can be set to less than 40 μm.

[0046] However, it is desirable to set the thickness of the film forming the packaging member 12 within the range of, for example, 20 μm to 100 μm. This is because by setting the thickness of the resin film to 20 μm or more, sufficient strength can be ensured for the packaging member 12 in which the laminate 11p is housed. Furthermore, by setting the thickness of the resin film to 100 μm or less, flexibility and lightness of the packaging member 12 can be ensured.

[0047] Furthermore, the form of the film forming the packaging member 12 is not particularly limited, and may include a single-layer film made of a resin material, a biodegradable material, a biomass material, etc., a laminated film made by stacking these, a film made by bonding or laminating a resin material, a biodegradable material, and / or a biomass material with pulp paper or a nonwoven fabric, a mixed film made from a mixture of multiple resin materials, etc.

[0048] The packaging form of the packaging member 12 is not limited to gusset packaging, but may be any packaging form that can maintain the degassed state at least after the degassing step. For example, gusset packaging, caramel packaging, pillow packaging, or a combination of these may be used.

[0049] <Density and measurement height of the compressed package of tissue paper stack before and after compression> In the packaging body 1 according to one embodiment of the present invention, Table 1 shows an example of the density and measured height of the compressed packaging body of a tissue paper stack (simply referred to as a stack) before and after compression.

[0050] The density was calculated by measuring the mass and volume of the laminate and dividing the mass by the volume. The volume of the laminate was calculated by measuring the length, width, and height of the approximately rectangular parallelepiped laminate from above the packaging material 12, subtracting the length of the packaging material 12 (which was about 40 μm thick) from each length, and using these values ​​as the length, width, and height of the laminate.

[0051] [Table 1]

[0052] Here, in Table 1, the "initial" state represents a state in which neither compression nor degassing has been performed, the "compressed and degassed" state represents a state in which the product has been compressed and degassed by the packaging device 2, and the "opened" state represents a state in which the product has been opened a certain period of time (approximately 10 days) after compression and degassing, allowing air to enter. The "opened" state can be an indicator of how much the product will return to its original state after being opened after compression and degassing.

[0053] In Table 1, "density" is the density calculated by the above method. The mass of the laminate when calculating the density is determined by measuring the mass of the laminate including the packaging material 12 and subtracting the mass of the packaging material 12 from the measured mass. The "height" is the length along the compression direction (the length in the stacking direction of five boxes of tissues) and is the height of the stack not including the thickness of the packaging member 12. The "height" can be a measure of the state before and after compression. The "density" before and after compression also serves as a measure of how much the compressed stack will return to its original state after opening.

[0054] Table 2 shows the measurement results of density and height according to the degree of compression of the laminate as Test Examples 1 to 5.

[0055] [Table 2]

[0056] The graph shows the density and the set height when five boxes of tissue paper stacks are compressed and deaerated to a set height (13.8 cm to 16.5 cm). In Test Example 1, the height is approximately 67% of the state before compression and deaeration, and in Test Example 5, the height is approximately 55% of the state before compression and deaeration. In all of Test Examples 1 to 5, the purpose of space saving through compression can be achieved, and the increased density makes it possible to increase the compressive strength of the entire package 1. In other words, by increasing the density through compression and deaeration, the package 1 not only has improved compressive strength in the stacking direction, but also has improved strength so that it can withstand deformation in a direction perpendicular to the stacking direction.

[0057] FIG. 7 shows a flow of a packaging process for producing the packaging body 1 according to this embodiment.

[0058] The packaging process using the packaging device 2 to produce the packaging body 1 of this embodiment includes the steps of storing a tissue paper stack 11p in a packaging member 12, placing the stored stack 11p at a first predetermined position P1, compressing the stack 11p placed at the first predetermined position P1 to a second predetermined position P2, evacuating the compressed packaging member 12, and sealing the opening 14 of the evacuated packaging member 12.

[0059] The worker who compresses and packages the tissue stack 11p first prepares the packaging device 2 and prepares to start packaging (Step S1), places five boxes' worth of tissue stacks 11p in a gusset bag 12 (Step S2), and prepares a tissue stack container 1p as shown in Fig. 2(a). Next, the tissue stack container 1p is placed on the bottom (i.e., first predetermined position P1) of the box 22 removed from the packaging device 2 (Step S3), and the box 22 is placed on a platform of the frame 21 of the packaging device 2 that can be moved up and down by the ram of the compressor 23 (Step S4). At this time, the top of the gusset bag 12 is left passing through the opening 241 of the upper plate 24. Next, the tissue stack 11p is compressed by the compressor 23 of the packaging device 2 (while pulling the top of the gusset bag 12 that has passed through the opening 241 of the upper plate 24) (Step S5). Then, the inside of the gusset bag 12 is evacuated using the deaerator 25 (step S6), and the opening 14 of the gusset bag 12 is sealed using the sealing means 26 (step S7), thereby obtaining the compressed packaged body 1 of the tissue paper stack shown in Figures 1 and 2(b), and the series of steps is completed (step S8). By compressing in this manner, sufficient compression and rigidity can be obtained, and the tissue paper becomes a (nearly) rigid rectangular parallelepiped, so that even when multiple compressed packaged bodies 1 of the tissue paper stack are stacked, they do not easily shift.

[0060] Conventionally, laminates of sanitary tissue paper have been packaged compactly in order to improve the transport efficiency of the laminates of sanitary tissue paper and reduce storage space. For example, Patent Document 1 describes a technology in which a bundle of tissue paper is placed inside a heat-shrinkable bundling film and heated to shrink the heat-shrinkable bundling film, thereby compressing the bundle of tissue paper into a compact size.

[0061] However, when compressing a stack of sanitary tissue paper, it is not enough to simply compress it strongly; it is necessary that the stack be able to restore its shape and be usable when the package is opened after compression. This point is not sufficiently considered in Patent Document 1, and there is still room for improvement in the structure of the package that compresses the stack of sanitary tissue paper so that the stack can restore its shape and be usable.

[0062] According to this embodiment, the stack 11p of stored sanitary thin paper is compressed so that it can be restored to its original shape and used, which in turn makes it possible to reduce material costs, logistics costs, and storage space.

[0063] <Other> The present invention is not limited to the above-described embodiments or the modifications described throughout, and appropriate changes and modifications can be made without departing from the technical concept of the present invention. For example, in the above-described embodiment, a handle hole that can be gripped to carry the packaging body 1 may be provided between the open end of the packaging bag 1 and the seal portion 13. In this case, the seal portion 13 may be positioned closer to the compressed body side 11 to ensure an area for forming the handle hole. In the present invention, the handle hole may have various shapes such as a pair of circles, an oval, an ellipse, etc. [Explanation of symbols]
