Absorbent product
In a standing part ( 342 ) of each side wall part ( 34 ) in an absorbent product ( 1 ), an inwardly bending part ( 3423 ) is formed between a first elastic member ( 35 ) and a second elastic member ( 36 ). When the absorbent product ( 1 ) is worn, the inwardly bending part ( 3423 ) where no elastic member is provided comes into contact with a wearer to be deformed into surface shape, and a portion in the vicinity of the inwardly bending part ( 3423 ) and the first elastic member ( 35 ) contacts with the wearer in surface shape. Therefore, the wearer is prevented from being compressed excessively by the first elastic member ( 35 ) and the second elastic member ( 36 ) and excrement is prevented from leaking out to the outer side of the absorbent product ( 1 ).
1. An absorbent product for receiving excrement from a wearer, the absorbent product comprising:
an outer covering sheet having leg elastic members which contract to form leg gathers;
a sheet-like main body part where an absorbent core is located between a back sheet and a top sheet, said main body part being attached on said outer covering sheet; and
a pair of side sheets located respectively on both side portions of said main body part, each of said side sheets comprising a strip-like bonded part bonded on said main body part and a side wall part which is continuous from said strip-like bonded part at an outside edge of said strip-like bonded part,
wherein said side wall parts are located respectively on both side portions of said main body part and extend in a longitudinal direction of said main body part, and each side wall part includes:
(i) a standing part standing up from said main body part at a middle portion of said side wall part in said longitudinal direction;
(ii) two side wall end parts which are both end portions of said side wall part in said longitudinal direction, the side wall end parts being fixed in a folded configuration over said main body part; and
(iii) an elastic member which is bonded to a free edge of said standing part along said free edge and which contracts to form gathers in said standing part; and
wherein each of the side wall end parts comprises:
(i) a first fixed part extending inwardly from the strip-like bonded part to an inwardly bending part which is continuous in said longitudinal direction with a portion of said standing part, said portion being in the vicinity of a fixed edge of said standing part, said first fixed part being fixed over said main body part; and
(ii) a second fixed part extending outwardly from the inwardly bending part to the free edge and disposed between said main body part and said first fixed part and being fixed over said main body part, and
wherein each of the side sheets further comprises an elastic member which extends along said fixed edge of said standing part.
2. The absorbent product according to claim 1 , wherein each of said side wall parts further comprises another elastic member which is bonded to said standing part at a position away from said free edge, said another elastic member extending in a direction substantially parallel with the longitudinal direction and contracting to form gathers in said standing part, and
wherein an inwardly bending part is formed in said standing part at a position between said elastic member bonded to said free edge and said another elastic member.
3. The absorbent product according to claim 2 , wherein said another elastic member is a plurality of elastic elements which are spaced apart in a direction orthogonal to said longitudinal direction and each of which extends in said longitudinal direction.
4. The absorbent product according to claim 2 , wherein a portion of said standing part being in the vicinity of said free edge is almost parallel with said main body part, or said portion is inclined so as to come closer to said main body part toward said free edge.
5. The absorbent product according to claim 2 , wherein said elastic member bonded to said free edge is a plurality of elastic elements which are spaced apart in a direction orthogonal to said longitudinal direction and each of which extends in said longitudinal direction.
6. The absorbent product according to claim 2 , wherein a width of said absorbent core at one end in said longitudinal direction is larger than a width of said absorbent core at a middle of said absorbent core in said longitudinal direction.
7. The absorbent product according to claim 2 , further comprising:
an auxiliary absorbent pad located on said main body part at a position between said pair of side wall parts, each side portion of said auxiliary absorbent pad being located between said main body part and said standing parts of said side wall parts.
8. The absorbent product according to claim 7 , wherein said auxiliary absorbent pad comprises:
a sheet-like auxiliary absorbent main body part; and
auxiliary absorbent side wall parts which are located on both side portions of said auxiliary absorbent main body part and which extend in said longitudinal direction of said auxiliary absorbent main body part, said auxiliary absorbent side wall parts standing up from said auxiliary absorbent main body part at least at a middle portion thereof in said longitudinal direction.
9. The absorbent product according to claim 1 , wherein said elastic member bonded to said free edge is a plurality of elastic elements which are spaced apart in a direction orthogonal to said longitudinal direction and each of which extends in said longitudinal direction.
10. The absorbent product according to claim 1 , wherein a width of said absorbent core at one end in said longitudinal direction is larger than a width of said absorbent core at a middle of said absorbent core in said longitudinal direction.
11. The absorbent product according to claim 1 , further comprising:
an auxiliary absorbent pad located on said main body part at a position between said pair of side wall parts, each side portion of said auxiliary absorbent pad being located between said main body part and said standing parts of said side wall parts.
12. The absorbent product according to claim 11 , wherein said auxiliary absorbent pad comprises:
a sheet-like auxiliary absorbent main body part; and
auxiliary absorbent side wall parts which are located on both side portions of said auxiliary absorbent main body part and which extend in said longitudinal direction of said auxiliary absorbent main body part, said auxiliary absorbent side wall parts standing up from said auxiliary absorbent main body part at least at a middle portion thereof in said longitudinal direction.
13. The absorbent product according to claim 1 , wherein the leg elastic members are disposed outwardly of the elastic members of the side wall parts in the width direction of said main body part.
14. The absorbent product according to claim 1 , wherein the outer covering sheet is disposed on an opposite side of the absorbent core from the top sheet in a thickness direction of the absorbent core,
wherein the outer covering sheet extends outwardly beyond the side wall part of each of the side sheets in the width direction of said main body part, and the leg elastic members are disposed outwardly of the elastic members of the side wall parts in the width direction of said main body part.
