Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view showing a diaper 1 employing a hook laminate according to the present embodiment. The diaper 1 is a member that covers the crotch portion of the wearer from the abdomen side to the back side with a sheet-like body 2. This allows the diaper 1 to absorb a target object discharged from the crotch portion of the wearer and prevent the target object from leaking. Note that the target object of the diaper 1 is moisture, solid, and semisolid, and examples thereof include urine and feces.

The main body 2 of the diaper comprises a back sheet; a liquid permeable top sheet laminated to the inner side of the back sheet; and an absorbent layer including a liquid absorbent polymer absorbent contained between the back sheet and the top sheet. The main body 2 includes a stomach-side edge 11, a back-side edge 12, a pair of crotch-

side edges

13A and 13B, and an absorbent region 14. The abdomen-side border 11 is a strip-shaped portion located on the wearer's abdomen side. The back side edge 12 is a strip-shaped portion located on the back side of the wearer. Since the diaper 1 of the present embodiment is an open-type diaper, the abdomen-side edge 11 and the back-side edge 12 are separated from each other. The hook laminated

bodies

50A, 50B according to the present embodiment are provided at the end portions 12a and 12B, respectively, on the side of the back side edge 12. The hook laminate 50A is bonded to the area near the end portion 11a on the side of the abdomen-side edge 11. The hook laminate 50B is bonded to the area near the end 11B on the side of the abdomen-side edge 11.

When the diaper 1 is worn by a wearer, the abdomen-side margin 11 is wrapped around a portion on the abdomen side of the wearer, the back-side margin 12 is wrapped around a portion on the back side of the wearer, and the abdomen-side margin 11 and the back-side margin 12 are fixed by the

hook laminates

50A, 50B. The crotch side edges 13A and 13B are edges extending between the abdomen side edge 11 and the back side edge 12. The crotch side edges 13A and 13B are arranged near the legs near the crotch portion of the wearer. The crotch side edges 13A and 13B are made stretchable.

Next, the hook laminated body 50 will be described with reference to fig. 2. Note that when referred to as "hook laminate 50", the hook laminate 50A and the hook laminate 50B will be described without distinction. Fig. 2 is an enlarged cross-sectional view of the hook laminate 50.

The hook laminated body 50 is a laminated body that overlaps with a target object to be joined thereto. When the hook laminate 50 is applied to the diaper 1, the object becomes the surface of the main body 2 of the diaper 1, i.e., a back sheet, a top sheet, and the like. These target objects are nonwoven fabrics and the like. The hook laminate 50 includes a hook member 51 and a base material 54. In other words, the hook laminate 50 is a laminate formed by laminating the hook member 51 and the base material 54.

The hook member 51 is a member that overlaps with the target object to be engaged to the target object. The hook member 51 includes a base portion 52 and a hook portion 53. Note that the base portion 52 and the hook portion 53 may be integrally formed of the same material. Materials for the hook member 51 include, for example, polyolefin homopolymers (such as polyethylene and polypropylene), copolymers of ethylene, propylene and/or butylene, copolymers containing ethylene (such as ethylene vinyl acetate and vinyl acrylate), poly (ethylene terephthalate); in general, those made of polyolefins (e.g., polyethylene, polypropylene, polybutylene, ethylene copolymers, propylene copolymers, butylene copolymers, and copolymers and blends of these materials) may be employed, in addition, the hook members 51 are preferably colors that can easily visually recognize visual information from an ink layer described later.

The base portion 52 is a sheet-like member which becomes a base material of the hook member 51. The base portion 52 has a major surface 52a and a major surface 52b on the opposite side. The thickness of the base portion 52 is not particularly limited, but may be set to 25 μm to 400 μm, and more preferably 50 μm to 250 μm. Sufficient strength with the hook member 51 can be ensured by setting the thickness of the base portion 52 to be greater than or equal to the lower limit value. In addition, by making the thickness of the base portion 52 less than or equal to the upper limit value, the ease of bending of the hook member 51 can be ensured, and visual information from an ink layer described later can be visually recognized easily.

The hook portion 53 is a member protruding from the one main surface 52a of the base portion 52. When the engagement target object is a nonwoven fabric, for example, the hook portion 53 can be engaged to the nonwoven fabric by entering the fibers and engaging the fibers. Note that, although omitted in fig. 2, a hook shape for engagement with the target object is formed at the distal end of the hook portion 53. The density of the hook portions 53 can be set to 1pin/mm ² To 50pin/mm ² And more preferably 2pin/mm ² To 20pin/mm ² . The height of the hook portion 53 may be set to 50 μm to 500 μm.

The base material 54 is a member laminated on the other side main surface 52b of the base portion 52 of the hook member 51. The base material 54 is a sheet-like member spread on the base portion 52. The base material 54 may be formed from materials such as, for example, nonwovens, cloths, knitted fabrics, woven fabrics, satin fabrics, gauzes, pile fabrics, films, composites thereof, and the like. The thickness of the base portion 52 is not particularly limited, but may be set to 25 μm to 400 μm, and more preferably 50 μm to 250 μm. The base material 54 is bonded to the major surface 52b of the base portion 52 by an adhesive layer 56. The adhesive layer 56 may be composed of, for example, an adhesive layer (such as an adhesive), and further, a molten layer formed by ultrasonic fusion, heat fusion, or the like, an assembly layer formed by mechanical bonding (such as embossing), or a combination thereof. The thickness of the adhesive layer 56 is not particularly limited, but may be set to be greater than or equal to 0 μm and less than or equal to 1000 μm, less than or equal to 500 μm, and more preferably less than or equal to 300 μm.

An ink layer 57 is formed between the base portion 52 and the base material 54. The ink layer 57 is a layer forming visual information such as characters, symbols, figures, patterns, and the like, which can be visually recognized. The visual information formed by the ink layer 57 can be visually recognized from the outside of the hook laminated body 50 by the hook member 51. The observer can visually recognize the visual information from the ink layer 57 from the main surface 52a side of the base portion 52.

In the example shown in fig. 1, the ink layer 57 is formed on the other side main surface 52b of the base portion 52. That is, the ink layer 57 is directly provided on the main surface 52b of the base portion 52. The ink layer 57 is formed on the main surface 52b of the base portion 52 by printing ink. The thickness of the ink layer 57 is not particularly limited, but is set to be thinner than the thickness of the adhesive layer 56. When the ink layer 57 is formed directly on the base portion 52, visual information from the ink layer 57 can be clearly confirmed when viewed from the hook portion 53 side, as shown in the photograph of fig. 4 (a).

Note that the ink layer 57 only needs to be formed between the base portion 52 and the base material 54, and the formation manner thereof is not particularly limited. For example, as shown in fig. 3, the ink layer 57 may be formed on the surface of the base material 54. However, in this case, the visual information from the ink layer 57 is visually recognized through the adhesive layer 56, and therefore, as shown in fig. 4 (b), the visibility is reduced as compared with fig. 4 (a).

The ink type of the ink layer 57 is not particularly limited. As the ink of the ink layer 57, a typical ink that expresses only colors may be used, or an ink having a special function may be used. For example, ink layer 57 may be formed from a temperature sensitive ink that changes color with temperature. Alternatively, the ink layer 57 may be formed of a pressure-sensitive ink that changes color with pressure.

Next, what type of visual information the ink layer 57 displays will be described.

When a worker puts the diaper 1 on the wearer, the ink layer 57 may display information visually recognized by the worker. For example, when the worker views the hook member 51 from the hook portion 53 side, the ink layer 57 may display visual information useful for the work of placing the diaper 1. Alternatively, the ink layer 57 may also display information that is visually recognized by the worker when the diaper is removed from the wearer. For example, when the diaper 1 is placed or removed, work content, preventive measures, and the like may be displayed on the hook laminate 50.

For example, the ink layer 57 may display visual information for disposal of the diaper 1 when the diaper 1 is removed. For example, in fig. 5, "B" and "a" are shown on the hook surface 50A of the hook laminated

body

50A, 50B as marks for guiding the operation at the time of disposal. In other words, "B", "a" (fig. 5 (B)) provided on the main body 2 can be visually recognized when the main body 2 of the diaper 1 is rolled up (fig. 5 (a)). The worker unfolds the

hook laminate

50A, 50B (fig. 5 (c)) and engages the marking so that the marking described on the hook surface 50A matches the marking of the body 2 (fig. 5 (d)). Therefore, the diaper 1 to be used can be rolled up and fixed by the

hook laminates

50A, 50B.

Alternatively, visual information for the work of overlapping the back side edge 12 when disposing the diaper 1 may be displayed. For example, in fig. 6, "Q" and "P" are shown on the hook surface 50A of the hook laminated

body

50A, 50B as marks for guiding the operation at the time of disposal (fig. 6 (a)). The rolled body 2 is also denoted by "P" and "Q" (fig. 6 (a)), and the back edge 12 is also denoted by "Q" and "P" (fig. 6 (b)). The hook laminate 50B having the mark "P" is engaged to match the mark "P" of the main body 2 (fig. 6 (c)). Then, the hook laminate 50A having the mark "Q" is matched and joined to the mark "Q" of the back-side edge 12 near the joined hook laminate 50B (fig. 6 (d)). Therefore, the diaper 1 to be used can be rolled up and fixed by the

hook laminates

50A, 50B.

Further, the ink layer 57 can display visual information that enhances entertainment when the diaper 1 is put on and removed from a wearer. As visual information for enhancing entertainment, the following operations can be adopted. For example, competitive features such as lottery tickets may be provided by displaying very few patterns appearing in one of the plurality of diapers 1. In addition, by randomly appearing words different from each other in the left hook laminated body 50A and the right hook laminated body 50B, visual information allowing a speech game with left and right can be displayed. In addition, a cartoon image or the like may be displayed.

The ink layer 57 may display visual information that enhances the design when the diaper 1 is worn on and removed from a wearer. As visual information for enhancing designability, the following operation can be adopted. For example, a first printed surface formed by ink layer 57 and a second printed surface of diaper 1 adjacent to hook laminate 50 in diaper 1 may be joined to construct a design. In addition, the hook laminate 50 includes a bonding region E2 bonded to the main body 2 of the diaper 1, and a protruding region E1 protruding from the main body 2 of the diaper 1 (see fig. 7). The design pattern formed by the ink layer 57 in the protruding region E1 of the hook laminate 50 and the design pattern of the portion adjacent to the protruding region E1 in the diaper 1 may be joined to each other to construct the design pattern. Note that the adhesive region E2 of the hook laminate 50 may be adhered so as to be embedded in the sheet material constituting the main body 2 of the diaper 1, or may be adhered to the surface of the sheet material so as to be exposed from the sheet material. When the adhesive area E2 is embedded in the body 2 of the diaper 1, the second printed surface F2 may be constituted by a surface of a sheet material of the diaper 1, or may be the adhesive area E2 of the hook laminate 50. When the bonded area E2 is the second printed surface F2, the design pattern can be seen through the sheet material of the diaper 1. When the adhesive area E2 is adhered to the surface of the sheet material so as to be exposed from the sheet material of the diaper 1, the adhesive area E2 serves as the second printing surface F2.

For example, the structure shown in fig. 7 may be employed. As shown in fig. 7 (a), the hook laminate 50 has a first printed surface F1 formed by the ink layer 57, and a second printed surface F2 of the diaper 1 adjacent to the hook laminate 50 in the diaper 1, the first printed surface and the second printed surface being joined to form a design of a penguin. The area of the design pattern of the second printing surface F2 is the same area as the bonding area E2. As shown in fig. 7 (b), the design pattern appears to the penguin to bow when the hook laminate 50 is bent between the projection areas E1 and the bonding areas E2. Note that the design pattern is not particularly limited, and may be a design pattern of another animal or human that bows.

For example, the structure shown in fig. 8 may be employed. In fig. 8, the second printed surface F2 of the main body 2 of the diaper 1 is a surface 2b (surface exposed to the outside when mounted) on the side opposite to the surface 2a on the side on which the first printed surface F1 of the hook laminate 50 is visually recognized. Specifically, as shown in fig. 8 (a), on the surface 2b on the outer side of the main body 2, a design pattern of the bear body is drawn on the back side of the user, and a design pattern of the long arm extending toward the abdominal side is drawn. As shown in fig. 8 (b), a design pattern of a bear's paw is drawn on the first printing surface F1 of the protruding region E1 of the hook laminate 50. Note that the protruding region E1 of the hook laminated body 50 itself is also formed in the shape of a bear hand. In contrast, as shown in fig. 8 (c), a design pattern of the back of the bear hand (colored in the color of the back of the bear hand) is drawn on the third printing surface F3 on the back side of the first printing surface F1 of the hook laminate 50. Further, the design pattern of the bear's arm is drawn in the form of a design pattern continued to the first printing surface F1 and a design pattern of the third printing surface F3 adjacent to the hook laminated body 50 in the second printing surface F2 of the diaper 1. In other words, the design pattern formed by the ink layer 57 in the protruding region E1 of the hook laminate 50 and the design pattern on the portion of the diaper 1 adjacent to the protruding region E1 are formed on opposite surfaces, but may be joined to each other to construct the design pattern. Thus, the design in which the bear extended the arms toward the abdomen and held the abdomen with the palm was completed. Note that the design pattern is not particularly limited, and may be a design pattern in which other animals or persons stick out their arms.

For example, the structure shown in fig. 9 may be employed. Fig. 9 (a) and 9 (b) show the diaper 1 having the design pattern drawn, and fig. 9 (c) and 9 (d) show the diaper 1 before the design pattern is drawn. As shown in fig. 9 (a), before the diaper 1 is used, a design pattern is drawn so that the entire diaper 1 seems like the face of a cow. The design pattern of the cow horns is drawn on the first printing surface F1 of the protruding region E1 of the hook laminated body 50. In the surface 2a on the side where the first printing surface F1 of the hook laminating body 50 is visually recognized, the design pattern of the base of corner is drawn on the second printing surface F2 adjacent to the protruding area E1 of the hook laminating body 50. Further, as shown in fig. 9 (b), a design pattern is drawn so as to present a pattern like a cow's body in a state where the diaper 1 is rolled up for disposal after use of the diaper 1. At this time, a design pattern of the cow body is drawn on the third printing surface F3 on the back side of the first printing surface F1 of the hook laminated body 50.

Further, the structure shown in fig. 10 may be employed. In fig. 10, a structure is provided in which a design pattern of a change belt is completed by fastening the diaper 1 with the hook laminate 50. As shown in fig. 10 (a), a design pattern indicating letters "hen" and "shin" is drawn on the first printing surface F1 of the protruding region E1 of the hook laminate 50. The design pattern of the front side of the conversion tape is drawn at a position corresponding to the abdomen of the main body 2 of the diaper 1. As shown in fig. 10 (b), a design pattern of a part of the tape portion of the conversion tape is drawn on the third printing surface F3 on the back side of the first printing surface F1 of the hook laminate 50. By fastening the hook laminate 50 to the main body 2 of the diaper 1, the hook laminate engages with the design pattern on the front side of the main body 2, thereby completing the design pattern of the conversion tape.

Next, the operation and effect of the hook laminating body 50 according to the present embodiment will be described.

The hook laminate 50 according to the present embodiment is a hook laminate 50 which is overlapped with a target object to be engaged with the target object, the hook laminate including a hook member 51 having a base portion 52 and a hook portion 53 protruding from one main surface 52a of the base portion 52; and a base material 54 laminated on the other side main surface 52b of the base portion 52 of the hook member 51, wherein an ink layer 57 is formed between the base portion 52 and the base material 54.

According to this hook laminating body 50, the ink layer 57 is formed between the base portion 52 and the base material 54. That is, the user can visually recognize the ink layer 57 seen from the opposite side of the base material 54 through the hook member 51, i.e., from the main surface 52a forming the hook portion 53. Therefore, by forming characters, symbols, figures, patterns, and the like from the ink layer 57, predetermined visual information can be displayed from the surface on the hook portion 53 side of the hook laminated body 50. Therefore, even in a scene other than a scene in which the hook laminate 50 is joined to a target object such as the diaper 1, predetermined visual information can be transmitted using the hook laminate 50. Therefore, a scene in which the visual information of the hook laminated body 50 can be visually recognized can be enlarged.

The ink layer 57 may be formed on the other side main surface 52b of the base portion 52. In this case, the ink layer 57 can be visually recognized without passing through the adhesive layer 56, and thus the visual information visibility of the ink layer 57 is enhanced.

The density of the hook portions may be set to 1pin/mm ² To 50pin/mm ² . In this case, when the target object is the diaper 1, an appropriate engagement force can be exhibited.

When a worker puts the diaper 1 on a wearer, the ink layer 57 may display information visually recognized by the worker. This allows visual information useful to the worker to be formed by the ink layer 57.

When a worker removes the diaper 1 from the wearer, the ink layer 57 may display information visually recognized by the worker. This allows visual information useful to the worker to be formed by the ink layer 57.

The ink layer 57 may be formed of a temperature sensitive ink that changes color with temperature. In addition, the ink layer 57 may be formed of a pressure-sensitive ink that changes color with pressure. This may increase the variation in the scene in which the ink layer 57 may display visual information.

The hook member 51 according to the present embodiment is a hook member 51 which overlaps with a target object to be engaged with the target object, the hook member having a base portion 52 and a hook portion 53 protruding from one main surface 52a of the base portion 52, wherein an ink layer 57 is formed on the other main surface 52b of the base portion 52.

The diaper 1 according to the present embodiment includes the above-described hook laminate 50 or the above-described hook member 51.

According to the hook member 51 and the diaper 1, the same object as the operation and effect of the above-described hook laminate 50 can be obtained.

The first printed surface F1 formed by the ink layer 57 and the second printed surface F2 of the diaper 1 adjacent to the hook laminate 50 in the diaper 1 may be joined to construct a design. In this case, the design pattern of the ink layer 57 of the hook laminate 50 according to the present embodiment and the design pattern on the diaper 1 side may be combined to enhance the design and entertainment of the diaper 1.

The hook laminate 50 includes a bonding region E2 bonded to the main body 2 of the diaper 1, and a protruding region E1 protruding from the main body 2 of the diaper 1, wherein a design pattern formed by the ink layer 57 in the protruding region E1 of the hook laminate 50 and a design pattern of a portion adjacent to the protruding region E1 in the diaper 1 may be engaged with each other to construct the design pattern. In this case, the design pattern of the ink layer 57 of the hook laminate 50 according to the present embodiment and the design pattern on the diaper 1 side may be combined to enhance the design and entertainment of the diaper 1.

The present invention is not intended to be limited to the above-described embodiments.

For example, the object of applying the hook laminate is not limited to diapers, and may be suitably employed as long as bonding to the object is performed using the hook laminate. For example, the hook laminate may be used in products such as garments, bags, and the like, other headrest pillow cases, and the like.
