Moisture absorbent article

Abstract

To provide a moisture absorbent article capable of coping with circumstances for example, there have been absorbent articles which suppress leakage by leakage prevention parts erected on a skin surface side, however, a gap is generated by a body posture and motion of the wearer in wearing, or the erected leakage prevention parts and three-dimensional gathering are fallen laterally, thereby causing leakage.SOLUTION: There is provided an absorbent article comprising: an absorber capable of absorbing moisture; an absorber holding part for holding the absorber. The absorber holding part has: a long-shaped bottom; a pair of longitudinal side walls which is erected from each side edge in a short direction of the bottom, and is provided on the side edges along the longitudinal direction; and belt-shaped eaves parts which are continuous from upper sides of the side wall parts and protrude to a center in the short direction. On one longitudinal side wall side of both side edges of respective eaves parts, there is a stretchable outer gathering part. On the other short direction center part, a stretchable inner gathering part is provided. By shrinkage of the inner and outer gathering parts, the longitudinal side wall parts are erected and an under-eaves space is formed under the eaves parts.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a moisture-absorbent article that can be applied to the excretory area so as to effectively absorb and retain urine, feces, etc. excreted from the body without allowing them to leak sideways. [Background technology]

[0002] Known examples of moisture-absorbent articles include disposable diapers, urine pads, and sanitary napkins. These moisture-absorbent articles have the function of preventing leakage of excrement, such as feces, urine, and menstrual blood, from the wearer. One method for achieving this function is to gather impermeable sheets arranged on both sides in the width direction with elastic thread or the like to stand them up, thereby sealing gaps that form between the skin surface and the moisture-absorbent article when worn, thereby preventing side leakage of excrement. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2024-8010 Summary of the Invention [Problem to be solved by the invention]

[0004] These moisture-absorbing products are worn by people and animals in a variety of positions, including standing, sitting, and lying down. Furthermore, the state of the material excreted varies, including urine, menstrual blood, and feces. Some products prevent leakage by using a leak-proof section that stands up on the skin-facing side, but these can leak when gaps appear depending on the wearer's position or movement, or when the standing leak-proof section or three-dimensional gathers tip over. Furthermore, when solid matter is excreted, it can roll off the leak-proof wall when the product is replaced. [Means for solving the problem]

[0005] In order to solve the above drawbacks, the moisture-absorbing article according to the present invention comprises: An absorbent that can absorb moisture, an absorbent body holding portion that holds the absorbent body; Equipped with The absorbent body holding portion is A long bottom portion that holds the absorbent body; a pair of longitudinal sidewall portions rising from both short-side edges of the bottom portion and provided on the both short-side edges along the longitudinal direction; a strip-shaped eave portion connected to each of the pair of longitudinal side wall portions from an upper end edge thereof and protruding toward a center side in the lateral direction; Equipped with A stretchable outer gathered portion is provided on one of the longitudinal side wall portions of both side edges of each of the belt-shaped eave portions, and a stretchable inner gathered portion is provided on the other of the longitudinal center portions, Both end portions of the pair of eave portions are fixed to both end portions of the absorber holding portion in the longitudinal direction, The outer gathered portion and the inner gathered portion are shrunk along the longitudinal direction, causing the longitudinal side wall portions to rise, thereby creating an under-eaves space under the eaves portion. [Effects of the Invention]

[0006] The moisture-absorbent article of the present invention can be placed on a diaper cover, sanitary shorts, or the like, or fixed with an adhesive and placed against the excretory area, and is an absorbent article for absorbing liquids excreted from the body and retaining solids, and has longitudinal side walls that stand up from both longitudinal edges of an absorbent body holding section, and both ends of an eave section that is connected to the upper edge of the longitudinal side walls are connected and fixed to both longitudinal ends of the absorbent body holding section, so that when the outer gathered section and the inner gathered section of the eave section contract, the eave section that protrudes toward the center in the lateral direction from the longitudinal side walls and the longitudinal side walls stand up, and as a result, a space under the eave section is formed between the underside of the eave section and the longitudinal side walls, and so even if liquid excreted on the absorbent body flows toward the longitudinal side walls, it is folded back in the space under the eave section, reducing the possibility of the liquid flowing over the longitudinal side walls and the eave section. Furthermore, since the eave portion is connected and fixed to both longitudinal ends of the absorbent holding portion across the entire width of the eave portion, even if a solid object pushes the longitudinal side wall portion outward, the upper end edge of the longitudinal side wall portion is prevented from tipping over sideways.

[0008] The moisture-absorbent article of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of a first embodiment of the present invention. As shown in FIG. 1, the moisture-absorbent article of this embodiment comprises an absorbent body (1) capable of absorbing moisture and an absorbent body holding portion (4) on which the absorbent body (1) is placed or stacked. The absorbent body holding portion (4) has a long bottom portion (2) on which the main portion of the absorbent body (1) is placed or stacked, and a pair of longitudinal side walls (3) are provided on both lateral edges of the bottom portion (2) in the lateral direction, rising from the lateral edges and extending along the longitudinal direction. A strip-shaped eave portion (5) is connected to the upper end of each longitudinal side wall (3) on both lateral edges, each of which protrudes toward the center in the lateral direction. The bottom portion (2), longitudinal side walls (3), and eave portion (5) together constitute the absorbent body holding portion (4). The absorbent body holding part (4) is configured to form a space inside, and the absorbent body (1) is placed or stacked inside the absorbent body holding part (4) so ​​that it does not move, for example, by thermocompression bonding or sandwiching it with a water-permeable sheet. The absorbent body (1) can be, for example, a commonly sold product in which water-absorbent polymer or the like is attached to fibers and sealed with a water-permeable sheet, or a sheet of water-absorbent fibers. Then, the absorbent body is covered and fixed to the bottom part (2) of the absorbent body holding part (4).

[0009] A stretchable outer gathered portion (6) is provided on the upper end side of one of the longitudinal side wall portions (3) on both side edges of the eave portion (5), and a stretchable inner gathered portion (7) is provided on the other, lateral center side. In addition, both end portions (8) of the eave portion (5) are connected and fixed to both longitudinal end portions (10) of the absorbent body holding portion (4) at end joint portions (9). When the outer gathered portion (6) and inner gathered portion (7) of the eave portion (5) contract, the longitudinal side wall portions (3) of the absorbent body holding portion (4) are formed to stand up.

[0010] Figure 2 shows the eaves portion (5) of the moisture-absorbent article of this embodiment shown in Figure 1 in an uncontracted state, i.e., a state in which both ends of the eaves portion (5) are stretched by pulling. As shown in Figure 2, the stretchable portions of the outer gathered portion (6) and inner gathered portion (7) may be stretchable only in the center portion rather than the entire edges of the eaves portion (5). The absorbent body (1) does not need to have the same shape and size as the bottom portion (2), and may be larger than the bottom portion (2) in the lateral direction and extend to the longitudinal sidewall portions (3). In addition, an edge sheet portion (11) with its outer side as a free end may be provided outside the outer gathered portion (6).

[0011] Figure 3 shows a cross section of the absorbent body holding portion (4) when the outer gathered portion (6) and inner gathered portion (7) contract as shown in Figure 1, causing the longitudinal sidewalls (3) to rise, forming overhanging portions (5), which, together with the bottom portion (2), form the absorbent body holding portion (4). As shown in Figure 3, longitudinal sidewalls (3) and overhanging portions (5) are formed at both ends of the lateral side from the bottom portion (2) at the longitudinal center, and an under-overhanging space (12) is formed below the overhanging portions (5), forming a space on the upper surface of the absorbent body (1). An opening is formed above the space between the overhanging portions (5) at both ends. An edge sheet portion (11), one end of which is free, is provided widthwise outward of the outer gathered portion (6) of the overhanging portion (5), i.e., the upper end of the longitudinal sidewalls (3). The edge sheet portion (11), eaves portion (5), longitudinal sidewall portions (3), and bottom portion (2) can be constructed from a continuous impermeable sheet (14). The eaves portion (5) can be formed by folding an impermeable sheet (14a) twice, sandwiching an elastic member (13) such as rubber between the two, and then gathering and shrinking the two to form a gathered portion. The absorbent body (1) may be placed or stacked not only on the bottom portion (2) but also on the longitudinal sidewall portions (3). Increasing the volume of the absorbent body (1) can improve its moisture retention. The absorbent body (1) may be placed or stacked on the impermeable sheet (14a) that constitutes the bottom portion (2) and the like, with a permeable sheet (14b) placed on top of it and secured between them. The edge sheet portion (11) can be freely bent outside the outer gathered portion (6).

[0012] Figure 4 is a cross-sectional view of the moisture-absorbent article of this embodiment in an unshrunk state as shown in Figure 2. The longitudinal side wall portions (3) can be made of an impermeable sheet (14a), and in this case, it is preferable to fold them under the overhanging portion (5). In this case, at each end joint (9) shown in Figure 2, the overhanging portion (5) and both ends of the folded longitudinal side wall portions (3) are connected and fixed to the upper surface of the absorber holding portion (4).

[0013] To use the moisture-absorbing article of the first embodiment of the present invention, as shown in FIG. 5, it is recommended to place it on a wearing device such as shorts (15) or a diaper cover, or to attach the bottom (2) of the absorbent body holding portion (4) to the wearing device using adhesive tape or the like and apply it to the excretory area of ​​the body. When worn with shorts (15) for menstruation, urinary incontinence, or infant toilet training, the eaves (5) contacts the skin at its full width, allowing it to be worn without crushing the longitudinal side walls (3) or the under-eaves space (12). Furthermore, as described in

[0010] , by gathering the eaves (5) only near the center, the longitudinal side walls (3) can be exposed only where necessary when worn. Furthermore, since the longitudinal side walls (3) do not stand up in the eaves (5) where no gathers are formed, the eaves (5) do not feel stiff when worn. The position of the gathers may be adjusted depending on the size of the absorbent body holding portion (4) and the wearing condition.

[0014] Conventional upright leakproof sections and three-dimensional side gathers are made of a thin, standing piece of fabric, and because the top edge is a single thin line, they can collapse due to body movement, posture, or lateral pressure, as shown in Figure 6. This causes the absorbent section (1) to come into contact with the skin surface (16) and gaps are easily created, allowing excrement to leak out. Furthermore, when changing diapers, solid objects can roll or hit the gathers, causing them to collapse sideways and roll off.

[0015] In the moisture-absorbent article of this embodiment, the wide, strip-shaped overhanging portion (5) comes into contact with the skin surface (16), making it difficult for gaps to form between the overhanging portion (5) and the skin surface (16), and as shown in Figure 7, excrement that has flowed into the under-overhanging space (12) is folded back by the overhanging portion (5), preventing it from adhering to the skin surface (16) and reducing leakage over the leak-barrier. Furthermore, since the width of the overhanging portion (5), i.e., both end portions (8) of the overhanging portion (5) on the extension of the inner gathered portion (7) are fixed at the end joints (9), when the longitudinal side wall portions (3) try to collapse, they are pulled by the overhanging portion (5), preventing the upper end edges of the longitudinal side wall portions (3), i.e., the outer gathered portions (6), from collapsing sideways.

[0016] Thus, upright leak-proof sections were previously designed to fill gaps that formed when the diaper was worn, but by connecting the strip-shaped eaves sections (5) to the longitudinal side walls (3), the eaves sections (5) come into contact with the skin, preventing the longitudinal side walls (3) from tipping over and creating a space between the excretory section and the absorbent body (1). In addition, the absorbent body (1) is placed on a single impermeable sheet (14a), and the eaves sections (5) and longitudinal side walls (3) can be made from the same impermeable sheet (14a), thereby reducing the manufacturing process and the cost of raw materials, etc.

[0017] As in the first embodiment, in case excrement does leak, it is advisable to provide a border sheet portion (11) to prevent shorts, etc. from getting soiled. The border sheet portion (11) can also be manufactured from a series of impermeable sheets (14a).

[0018] The visor portion (5) is a wide band-like member and is composed of two stretchable portions, an inner gathered portion (7) and an outer gathered portion (6), but it may be composed of more than two gathered portions, such as by providing another gathered portion between the inner gathered portion (7) and the outer gathered portion (6).

[0019] 8 shows that the moisture-absorbent article of the present invention can be made into a disposable pet diaper by attaching bands (17) and connectors (18) in series and wrapping them around the body. In this case, by contracting the gathered portions of the outer gathered portion (6) and the inner gathered portion (7) along the entire longitudinal direction of the eave portion (5), not only the longitudinal side walls (3) connected along the eave portion (5) but also the lateral side walls (19) on both longitudinal ends (10) of the absorber holding portion (4), i.e., along the lateral direction, are formed.

[0020] As shown in Figure 9, when the absorbent holder (4) is attached to a pet, the longitudinal side wall (3) and the lateral side wall (19) are formed around the bottom (2) of the absorbent holder (4), and the absorbent holder (4) is attached to the skin surface by the eaves (5), so that an internal space is formed in the absorbent holder (4), which reduces stuffiness around the excretory area.

[0021] As shown in Figure 10, the moisture-absorbing article of the present invention can be placed on a diaper (20) that can be worn on the body, or fixed with adhesive tape, etc., or as shown in Figure 11, it can also be made into an integrated diaper using all disposable materials.
