Description

  The present invention relates to an absorbent article formed into a bag shape by bending a planar absorbent pad.

  2. Description of the Related Art Conventionally, a planar absorbent pad used by being disposed inside an outer such as disposable pants is known. Such an absorption pad has an absorber and is mainly intended for absorption of the user's urine. When an absorbent pad is used, it is economical because when the user urinates, only the absorbent pad needs to be replaced without replacing the entire outer.

  In recent years, an absorbent article for men called a urine collection bag formed by folding a planar absorbent pad into a bag shape has also been proposed. This urine collection bag is used by accommodating a male genitalia of the user in its internal space.

<1. First Embodiment>
<1-1. Configuration of urine collection bag>
FIG. 1 is a view showing a urine collection bag 1a which is an absorbent article according to the first embodiment. This urine collection bag 1a is mainly used as an auxiliary absorbent device for men and is disposed inside other worn articles (outer) such as disposable pants, and absorbs the excrement (mainly urine) of the user.

  As shown in FIG. 1, the urine collection bag 1 a has a bag shape having an opening 19. When the urine collection bag 1 a is used, the wearer's male genitalia is inserted into the opening 19. Thereby, a wearer's urine is discharge | released to the internal space of the urine collection bag 1a, and is absorbed by an internal absorber. Such a urine collection bag 1a is formed by bending a planar absorption pad into a bag shape.

  FIG. 2 is a view showing the absorption pad 2a which is the urine collection bag 1a before being folded into a bag shape, and shows a state from the side corresponding to the inside of the urine collection bag 1a. 3 is a cross-sectional view at the position III-III in FIG. 2, and FIG. 4 is a cross-sectional view at the position IV-IV in FIG. Hereinafter, the side of the absorption pad 2a corresponding to the inside of the urine collection bag 1a is referred to as “inside equivalent side”, and the side of the absorption pad 2a corresponding to the outside of the urine collection bag 1a is referred to as “external equivalent side”.

  As shown in the figure, the absorbent pad 2a has a substantially rectangular shape as a whole. The absorption pad 2a has a laminated structure in which an absorbent body 3 that absorbs urine is sandwiched between a top sheet 4 and a back sheet 5 (see FIGS. 3 and 4). These three members are arranged in the order of the top sheet 4, the absorber 3, and the back sheet 5 from the side corresponding to the inside. That is, the back sheet 5 is disposed on the outer equivalent side of the absorber 3 and the top sheet 4.

  The absorber 3 has a substantially rectangular shape, and is arranged such that its longitudinal direction is along the longitudinal direction of the absorbent pad 2a. The absorbent body 3 is configured, for example, by wrapping an absorbent core obtained by mixing a granular polymer (polymer water absorbent) in a hydrophilic fiber aggregate layer such as pulverized pulp fiber or cellulose fiber with a covering sheet such as tissue paper. .

  The top sheet 4 has a substantially rectangular shape, and is disposed so as to cover the entire main surface on the side corresponding to the inside of the absorber 3. The absorber 3 is bonded to the top sheet 4 with the entire main surface corresponding to the inside by an adhesive. A liquid-permeable nonwoven fabric is employed as the material for the topsheet 4.

  The back sheet 5 also has a substantially rectangular shape, but is folded in a bellows shape along a line along the longitudinal direction of the absorbent pad 2a and has a plurality of ridges 59 (see FIG. 3). Thereby, the main surface of the back sheet 5 is in a state of being contracted in the short direction of the absorbent pad 2a. The size of the main surface of the back sheet 5 in the contracted state is substantially the same as the size of the main surface of the top sheet 4.

  The back sheet 5 is configured by bonding two sheets, a liquid-permeable sheet 51 composed of a liquid-permeable nonwoven fabric and a water-repellent sheet 52 composed of a water-repellent nonwoven fabric (FIGS. 3 and 4). reference.). Therefore, the entire back sheet 5 is water repellent. The liquid permeable sheet 51 is disposed closer to the inside than the water repellent sheet 52. In addition, a large number of granular polymers (polymer water-absorbing bodies) 53 are dispersed and disposed between the liquid-permeable sheet 51 and the water-repellent sheet 52.

  As a liquid-permeable nonwoven fabric used for the surface sheet 4 or the liquid-permeable sheet 51, a nonwoven fabric using hydrophilic fibers (cellulose, rayon, cotton, etc.) or hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon) Etc.), and a non-woven fabric made liquid-permeable by treating with a surfactant.

  On the other hand, the water-repellent nonwoven fabric used for the water-repellent sheet 52 includes a nonwoven fabric using hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.). In place of the water-repellent nonwoven fabric, a plastic film, a composite material of the nonwoven fabric and the plastic film, or the like may be used.

  The top sheet 4 and the back sheet 5 are bonded to each other at the bonding portions 21 at both ends in the longitudinal direction of the absorbent pad 2a by heat fusion. Further, the plurality of ridges 59 of the back sheet 5 are also fixed at the bonding portion 21 by heat fusion. As described above, since the plurality of flanges 59 are fixed by heat fusion, they can be fixed more strongly than fixing using an adhesive or the like. For this reason, even if it fixes several ridges 59 only by the edge part, the folding state can be stabilized.

  As described above, the absorbent body 3 is fixed to the top sheet 4, but not bonded to the back sheet 5. Further, the top sheet 4 is bonded to the back sheet 5 in an end region where the absorber 3 is not fixed. Accordingly, a space is formed between the absorber 3 and the back sheet 5. Since the position of the absorbent body 3 in the absorbent pad 2a is fixed by the top sheet 4, the top sheet 4 can be expressed as a fixed sheet to which the absorbent body 3 is fixed.

  The urine collection bag 1a is formed by folding the absorption pad 2a configured as described above into a bag shape. That is, the absorbent pad 2a is bent along the folding line L along the short direction, with the inner equivalent side being the inner side. The folding line L is a substantially central line in the longitudinal direction of the absorbent pad 2a. As shown in FIG. 1, the side edge portions (both ends in the short direction of the absorbent pad 2 a) 29 facing each other by bending are bonded to each other at the bonding portion 11 by thermal fusion. The absorber 3 does not exist at the position of the adhesive portion 11. Thereby, the substantially rectangular bag-shaped urine collection bag 1a which has the opening part 19 is formed.

  The positions corresponding to both ends in the longitudinal direction of the absorption pad 2a are the openings 19 of the urine collection bag 1a. In the urine collection bag 1a, the back sheet 5 is disposed on the outermost side (outside of the top sheet 4 and the absorber 3). For this reason, the bag 59 of the back sheet 5 is exposed to the outside of the urine collection bag 1a. The longitudinal direction of the absorption pad 2a corresponds to the longitudinal direction of the urine collection bag 1a, and the short direction of the absorption pad 2a corresponds to the short direction of the urine collection bag 1a. Therefore, the bag 59 of the back sheet 5 is disposed along the longitudinal direction of the urine collection bag 1a.

  FIG. 5 is a cross-sectional view along the short direction of the urine collection bag 1a at the VV position in FIG. In the bonding portions 11 at both ends in the short direction of the urine collection bag 1a, the side edge portions 29 (layers composed of the top sheet 4 and the back sheet 5) facing each other by bonding are bonded to each other. That is, the top sheet 4 and the back sheet 5 are bonded at the bonding portion 11.

  Moreover, in the inside of the urine collection bag 1a, a first space R1 between the facing top sheets 4 and a second space R2 between the absorber 3 and the back sheet 5 exist. The first space R1 is directly connected to the outside through the opening 19.

  In the urine collection bag 1a, it is possible to extend the bag 59 of the back sheet 5 due to the presence of the second space R2. The urine collection bag 1a is shipped in a state where the bag 59 is not stretched (as shown in FIG. 1) as a product, and the bag 59 is stretched when actually used.

<1-2. Use of urine collection bag>
Next, the mode of use of the urine collection bag 1a will be described. FIG. 6 is a diagram illustrating a state in which the ridge 59 of the back sheet 5 is extended in the urine collection bag 1a. 7 is a cross-sectional view at the position VII-VII in FIG. 6, and FIG. 8 is a cross-sectional view at the position VIII-VIII in FIG.

  As shown in these drawings, the urine collection bag 1a can expand the area of the back sheet 5 in the short direction by extending the ridge 59. As a result, the second space R2 between the absorber 3 and the back sheet 5 can be enlarged inside the urine collection bag 1a.

  When using the urine collection bag 1a, first, after extending the ridge 59 of the back sheet 5 in this way, the user's male genitalia is inserted through the opening 19 and accommodated in the first space R1 inside the urine collection bag 1a. To do. Then, as shown in FIG. 9, the user wears an outer 9 such as disposable pants (pants-type diapers) or general underwear, and the urine collection bag 1 a is arranged inside the outer 9.

  FIG. 9 is a view of the positional relationship between the urine collection bag 1a and the outer 9 as seen from the direction corresponding to the left side of the user. In FIG. 9, the left side in the figure corresponds to the front side of the user. The right side of the urine collection bag 1a in the drawing is the skin side where the user is present, and the opposite side of the urine collection bag 1a in the drawing is the outer side where the outer 9 is present.

  Assume that the user urinates in such a state of use. Since the male genitalia is accommodated in the first space R1 of the urine collection bag 1a, all of the user's urine is first discharged into the first space R1 of the urine collection bag 1a.

  The urine released into the first space R1 enters toward the bottom of the first space R1 and passes through the liquid-permeable topsheet 4. And a part of urine which permeate | transmitted the surface sheet 4 is absorbed into the absorber 3 as it is. On the other hand, another part of the urine that has passed through the top sheet 4 enters the second space R2 between the absorber 3 and the back sheet 5, and is accumulated in the second space R2.

  Thereby, urine enters the absorber 3 from both the first space R1 and the second space R2. That is, since the contact area with the urine of the absorber 3 can be increased, the urine is efficiently absorbed by the absorber 3 and the urine absorption efficiency can be improved. Further, since the second space R2 is not connected to the opening 19, the urine that has entered the second space R2 is difficult to leak out. As a result, leakage of urine to the outside in the urine collection bag 1a can be effectively prevented.

  Further, in the urine collection bag 1a, a relatively wide space can be secured as the second space R2 by extending the plurality of ridges 59 of the back sheet 5. For this reason, a large amount of urine can be accumulated in the second space R2. As a result, urine absorption efficiency can be further improved, and leakage of urine to the outside can be more effectively prevented.

  Further, the back sheet 5 includes a large number of granular polymers 53 between the inner liquid-permeable sheet 51 and the outer water-repellent sheet 52. For this reason, the urine accumulated in the second space R <b> 2 passes through the liquid-permeable sheet 51 of the back sheet 5 and is also absorbed by the polymer 53. That is, not only the absorber 3 but also the back sheet 5 can absorb urine accumulated in the second space R2. Therefore, the urine absorption efficiency as a whole of the urine collection bag 1a can be greatly improved.

  As described above, the urine collection bag 1a of the present embodiment is formed by bending the planar absorption pad 2a. The absorbent pad 2 a includes a liquid-permeable top sheet 4, an absorbent body 3 that absorbs urine, and a water-repellent back sheet 5 in a layered form from the inside equivalent side. And while the absorber 3 is fixed to the top sheet 4, it is not bonded to the back sheet 5. Further, the top sheet 4 is bonded to the back sheet 5 in a region where the absorber 3 does not exist. For this reason, 2nd space R2 can be formed between the absorber 3 and the back sheet | seat 5 in the inside of the urine collection bag 1a. Since urine can also be accumulated in the formed second space R2, urine absorption efficiency can be improved. Further, since the plurality of ridges 59 of the back sheet 5 can be extended, a relatively wide space can be secured for accumulating urine.

<2. Second Embodiment>
Next, a second embodiment will be described. The urine collection bag of the present embodiment is also formed by folding a planar absorption pad into a bag shape. However, the structure of the absorption pad is different from that of the first embodiment.

  FIG. 10 shows a state from the side corresponding to the inside of the absorption pad 2b for forming the urine collection bag of the second embodiment. 11 is a cross-sectional view at the XI-XI position in FIG. 10, and FIG. 12 is a cross-sectional view at the XII-XII position in FIG.

  Also in the present embodiment, the absorbent pad 2b includes the absorber 3, the top sheet 4, and the back sheet 5. The materials of these members are the same as those in the first embodiment. Further, as in the first embodiment, the back sheet 5 has a plurality of ridges 59.

  However, the absorber 3 is in a state of being entirely wrapped by the top sheet 4. And this surface sheet 4 is fixed to the back sheet 5 by heat sealing | bonding in the adhesion part 21 of the both ends of the longitudinal direction of the absorption pad 2b in the state which wrapped the absorber 3. FIG. The absorber 3 does not exist at the position of the bonding portion 21.

  Therefore, also in the absorbent pad 2b of the present embodiment, the absorbent body 3 is fixed to the top sheet 4 and is not bonded to the back sheet 5. At the same time, the top sheet 4 is bonded to the back sheet 5 in an end region where the absorber 3 is not fixed. Thereby, a space (second space R2) is formed between the absorber 3 and the back sheet 5. Also in the absorbent pad 2b of the present embodiment, the top sheet 4 can be expressed as a fixed sheet to which the absorber 3 is fixed.

  Moreover, the length of the top sheet 4 in a state of wrapping the absorbent body 3 is shorter than the back sheet 5 in a folded state with respect to the short side direction of the absorbent pad 2b. For this reason, in the side edge part 29, the surface sheet 4 does not exist and it is in the state in which only the back sheet 5 exists.

  The urine collection bag 1b of the second embodiment is formed by folding the absorption pad 2b configured as described above into a bag shape. The appearance of the urine collection bag 1b formed in this way is the same as that shown in FIG. Also in the present embodiment, the absorbent pad 2b is bent along the folding line L with the inner side corresponding to the inner side, and the opposing side edge portions 29 are bonded to each other by thermal fusion at the bonding portion 11.

  FIG. 13 is a cross-sectional view along the short direction of the urine collection bag 1b of the present embodiment at a position corresponding to the V-V position of FIG. In the adhesive portions 11 at both ends in the short direction of the urine collection bag 1b, the side edge portions 29 facing each other are bonded by bending. That is, the back sheets 5 are bonded to each other at the bonding portion 11.

  Therefore, the back sheet 5 and the top sheet 4 are not bonded at both ends in the short direction of the urine collection bag 1b of the present embodiment. That is, in the urine collection bag 1b, the top sheet 4 is bonded to the back sheet 5 only in the vicinity of the opening 19 corresponding to both ends in the longitudinal direction of the absorption pad 2b.

  Thus, in the urine collection bag 1b of the present embodiment, the back sheet 5 and the top sheet 4 are not bonded at both ends in the short direction. For this reason, in the inside of the urine collection bag 1b, the first space R1 between the facing top sheets 4 (that is, the absorbent bodies 3 wrapped around them) and the first space R1 between the absorbent body 3 and the back sheet 5 are used. The two spaces R2 are connected. At the same time, the urine collection bag 1b can easily extend the bag 59 of the back sheet 5.

  FIG. 14 is a diagram illustrating a state in which the ridge 59 of the back sheet 5 is extended in the urine collection bag 1b of the present embodiment. FIG. 15 is a cross-sectional view at the position XV-XV in FIG. In the urine collection bag 1b of the present embodiment, the back sheet 5 and the top sheet 4 are not bonded at both ends in the short direction, and therefore, the top sheet 4 is affected along the short direction of the urine collection bag 1b. The back sheet 5 can be stretched without the need.

  In the urine collection bag 1a of the first embodiment described above, the back sheet 5 and the top sheet 4 are bonded at both ends in the short direction, as can be seen with reference to FIGS. For this reason, in the urine collection bag 1a of the first embodiment, the back sheet 5 cannot be stretched beyond the length of the top sheet 4 even if both ends of the back sheet 5 are pulled along the short direction. On the other hand, in the urine collection bag 1b of the second embodiment shown in FIGS. 13 to 15, the back sheet 5 can be stretched along the short direction without being affected by the top sheet 4. For this reason, the collar 59 of the back sheet 5 can be easily extended only by pulling the both ends of the back sheet 5 along the short direction of the urine collection bag 1b.

  This urine collection bag 1b can also be used as in the first embodiment. Since the first space R1 and the second space R2 are connected inside the urine collection bag 1b of the present embodiment, the urine that has entered the first space R1 is quickly transferred to the second space R2 and accumulated. It is possible to make it.

  In the above embodiment, it has been described that the topsheet 4 wraps the absorbent body 3 in the absorbent pad 2b. On the other hand, a surface sheet 4 having a shorter length than the folded back sheet 5 is provided in the short direction of the absorption pad 2c, as in the absorption pad 2c shown in FIG. Alternatively, the absorbent body 3 may be adhered. Also in this case, only the back sheet 5 is present at the side edge portion 29. Therefore, even when the absorption pad 2c is bent to form a urine collection bag, the back sheet 5 and the top sheet 4 can be prevented from being bonded at both ends in the short direction.

  Moreover, with the said form, the surface sheet 4 and the back surface sheet 5 were adhere | attached directly in the both ends of the longitudinal direction of the absorption pad 2b. On the other hand, even if the end sheet 41 is bonded to both ends in the longitudinal direction of the top sheet 4 and the end sheet 41 and the back sheet 5 are bonded as in the absorbent pad 2d shown in FIGS. Good. 18 is a cross-sectional view at the position XVIII-XVIII in FIG.

  As such an end sheet 41, a water-repellent nonwoven fabric can be adopted. Thus, by arranging the end sheets 41 at both ends in the longitudinal direction of the surface sheet 4, the surface sheet 4 can be securely fixed, and urine oozes out from both ends in the longitudinal direction of the surface sheet 4. Is prevented. In this case, since the position of the absorber 3 is fixed by both the top sheet 4 and the end sheet 41, the structure in which the top sheet 4 and the end sheet 41 are combined fixes the absorber 3. It can be expressed as a fixed sheet.

<3. Third Embodiment>
Next, a third embodiment will be described. The urine collection bag of the present embodiment is substantially the same as that of the first embodiment, but is different in that the absorber 3 is composed of a plurality of sub-absorbers.

  FIG. 19 shows a state from the side corresponding to the inside of the absorption pad 2e for forming the urine collection bag of the third embodiment. As shown in the figure, in the present embodiment, the absorber 3 is composed of two sub-absorbers 31. These two sub-absorbers 31 are arranged so as to be separated from each other and symmetrical with respect to the folding line L. That is, the boundary region 32 between the two sub absorbers 31 is along the folding line L. In other words, it can be expressed that the absorber 3 is divided into two along the folding line L.

  Each of these two sub-absorbers 31 is bonded to the topsheet 4 as in the first embodiment. The material itself of the sub-absorber 31 may be the same as the material of the absorber 3 of the first embodiment.

  Further, in the portion of the topsheet 4 corresponding to the boundary region 32 between the two sub-absorbers 31, a plurality of (through the space (second space R2) between the absorber 3 and the backsheet 5 and the outside ( Three through holes 42 are formed in the figure. In other words, it can be expressed that a plurality of through holes 42 are formed along the folding line L in the topsheet 4.

  FIG. 20 is a cross-sectional view along the longitudinal direction of the urine collection bag 1e of the present embodiment formed by bending the absorption pad 2e shown in FIG. In the urine collection bag 1e, the plurality of sub-absorbers 31 are arranged apart from each other, so that each sub-absorber 31 can efficiently absorb urine without being influenced by the other sub-absorbers 31.

  Further, since the boundary region 32 between the sub-absorbers 31 is along the folding line L, no absorber is disposed at the bottom of the urine collection bag 1e. Since urine easily collects at the bottom of the urine collection bag 1e, when a part of the absorber is present at the bottom, the part of the absorber corresponding to the bottom is greatly expanded as compared with other parts. As a result, there is a possibility that the expanded absorbent portion may inhibit the urine from entering the second space R2. On the other hand, by preventing the absorber from being present at the bottom of the urine collection bag 1e as in the present embodiment, it is possible to prevent the inflated absorber from obstructing entry of urine, so that the urine can be smoothly discharged. It is possible to shift to the two space R2.

  Further, since a plurality of through holes 42 are formed in the portion of the topsheet 4 corresponding to the boundary region 32 between the sub-absorbers 31, the through holes 42 are arranged at the bottom of the urine collection bag 1e. And through this through-hole 42, 1st space R1 and 2nd space R2 inside urine collection bag 1e penetrate and are connected. Therefore, urine accumulated at the bottom of the urine collection bag 1e can be more smoothly transferred to the second space R2.

<4. Fourth Embodiment>
Next, a fourth embodiment will be described. In 3rd Embodiment, although the absorber 3 was divided | segmented into two along the folding line L, in 4th Embodiment, the absorber 3 is a center line of the transversal direction of an absorption pad. It is divided into two along.

  FIG. 21 shows a state from the side corresponding to the inside of the absorption pad 2f for forming the urine collection bag of the fourth embodiment. As shown in the figure, also in the present embodiment, the absorber 3 is composed of two sub-absorbers 31. These two sub-absorbers 31 are arranged so as to be separated from each other and symmetrical with respect to the center line Lc in the short direction of the absorbent pad 2f. That is, the boundary region 32 between the two sub-absorbers 31 is along the center line Lc in the short direction of the absorbent pad 2f.

  In the urine collection bag formed by bending the absorption pad 2f, the absorbent body is not disposed in the central portion in the short direction. Usually, the central portion of the urine collection bag in the short direction is the main entry route of urine released from the male genitalia.
