Adhesive portion 71 is formed between surface patch 20 and lateral plate 60.Adhesive portion 71 is formed by known bond mediums such as hot melt adhesives, and between the ora terminalis 20b and the ora terminalis 20c of the opposing party of a side of surface patch 20, longitudinally Y extends continuously.By extending continuously in this wise, sealing state can be formed by adhesive portion 71, can prevent body fluid from leaking outside the horizontal X of adhesive portion 71.
The inner side ora terminalis of adhesive portion 71 is separated from the medial border 60a of lateral plate 60 to the outside of horizontal X, and outside it, ora terminalis is separated from the lateral margin 20a of surface patch 20 to the inner side of horizontal X.Adhesive portion 71 is formed discretely from the medial border 60a of the lateral plate 60 and lateral margin 20a of surface patch 20 respectively, thereby, it is possible to prevent the bond mediums such as hot melt adhesives from overflowing from each lateral margin in advance.Adhesive portion 71 can longitudinally Y be continuous with linearity, also can describe curve or helical form, and longitudinally Y extends and continuous incessantly on one side.
Between lateral plate 60 and hot melt property sheet 50, be formed with the melt-coating part 72 obtained based on heating, pressurizeing.Particularly, such as, by make stacked lateral plate 60, surface patch 20 and hot melt property sheet 50 between knurling rolls and anvil roller by carrying out heating, pressurizeing, namely between these sheet materials, form melt-coating part 72 by so-called embossing process.By this embossing process, and form recess from lateral plate 60 to hot melt property sheet 50, and form melt-coating part 72 on the position corresponding with this recess.Lateral plate 60 and hot melt property sheet 50 are preferably, the degree of perforate on these sheet materials 50,60 can not be heated, pressurize.Heating-up temperature is such as set to about 100 ~ 130 DEG C, and suitably changes pressure accordingly with the shape of the projection of knurling rolls, thereby, it is possible to realize can not the heating of the degree of perforate on sheet material, pressurization.
Lateral plate 60 and hot melt property sheet 50, containing thermoplastic resin, therefore, can make these thermoplastic resin meltings by heating.The resin of melting via the perforate 21 of surface patch 20 hot melt adhesion mutually, and makes lateral plate 60 and hot melt property sheet 50 engage in melt-coating part 72 by pressurization.Like this, by forming melt-coating part 72, and surface patch 20 can be made reliably to engage between lateral plate 60 and hot melt property sheet 50, and can prevent these sheet materials from peeling off.
Melt-coating part 72 has: the inner side melt-coating part 72a being positioned at the medial border 60a near zone of lateral plate 60; Be positioned at the outside melt-coating part 72c of the horizontal X exterior lateral area of inner side melt-coating part 72a and be positioned at the central melt-coating part 72b of zone line of melt-coating part 72a inside these, outside melt-coating part 72c.The size of longitudinal Y of inner side melt-coating part 72a, larger than the size of longitudinal Y of central melt-coating part 72b, the size of longitudinal Y of central melt-coating part 72b is larger than the size of longitudinal Y of outside melt-coating part 72c.In addition, the size of space of longitudinal Y of inner side melt-coating part 72a is less than the size of space of longitudinal Y of central melt-coating part 72b, and the size of space of longitudinal Y of central melt-coating part 72b is less than the size of space of longitudinal Y of outside melt-coating part 72c.Therefore, in the near zone of medial border 60a being formed with inner side melt-coating part 72a, it is maximum that the area of the inner side melt-coating part 72a of per unit area is compared with the area of the outside melt-coating part 72c of the per unit area in exterior lateral area with the central area of melt-coating part 72b of the per unit area in zone line.In other words, in the near zone of the medial border 60a of lateral plate 60, the density of melt-coating part is comparatively large, and diminishes outside the horizontal X of lateral plate 60.Therefore, lateral plate 60 and surface patch 20 are engaged at melt-coating part 72a place, inner side the most securely.The medial border 60a of lateral plate 60 does not form adhesive portion 71, therefore, although lateral plate 60 and surface patch 20 are not bonded with each other via adhesive portion 71, but engage securely in the melt-coating part 72a of inner side as described above, thus, the medial border 60a of lateral plate 60 and surface patch 20 reliably can be fixed, and when the packaging, use etc. of sanitary towel, roll with preventing the non-original idea of medial border 60a of lateral plate 60.
Outside melt-coating part 72c's is overlapping with adhesive portion 71 at least partially.Therefore, in the part that melt-coating part 72 is overlapping with adhesive portion 71, lateral plate 60 and hot melt property sheet 50 are engaged more firmly via surface patch 20.In addition, under the state being formed with adhesive portion 71, when implementing above-mentioned embossing process, form the hot melt adhesives melting by heating again of adhesive portion 71, and enter in the perforate 21 of surface patch 20, thereby, it is possible to more firmly lateral plate 60, surface patch 20 and hot melt property sheet 50 are engaged.
Extrude bar groove 22 is formed with towards absorber 40 from surface patch 20.Extrude bar groove 22 is by heating from surface patch 20 towards absorber 40, pressurize and formed.By forming extrude bar groove 22 in this wise, and keeping the shape of absorber 40, preventing the bulk deformation of sanitary towel 1.In addition, although not shown, but the lateral margin of the lateral border 60b of lateral plate 60 and back sheet 30 by heating, pressurization and be bonded with each other.In addition, be preferably, along its length, be alternately arranged extrude bar groove 22 low-density protuberance and highdensity recess.
In above-mentioned sanitary towel 1, surface patch 20 is engaged with lateral plate 60 by adhesive portion 71, and lateral plate 60 and hot melt property sheet 50 are via perforate 21 and be bonded with each other by melt-coating part 72, thereby, it is possible to surface patch 20 is reliably fixed between these sheet materials 50,60.Even if when employing the cotton fiber as non-hot melt property fiber as surface patch 20, also can make lateral plate 60 and hot melt property sheet 50 thermally welded across surface patch 20, therefore, surface patch 20 can not be peeled off from these sheet materials.In addition, adhesive portion 71 and melt-coating part 72 are overlapping in a part, and therefore, surface patch 20 and lateral plate 60 are engaged more firmly, can more be difficult to peel off.In addition, even if when not forming perforate 21 on surface patch 20, also the thermoplastic resin of lateral plate and hot melt property sheet 50 can be bonded with each other via the fibre gap of surface patch 20.
The perforate 21 of surface patch 20 is formed by fluid jet, but is not limited to this, such as, also the thorns such as pin can be formed perforate 21 on surface patch 20.But, when utilizing acupuncture to form perforate 21, likely on the face of one party, form protuberance.Surface patch 20 is formed with protuberance, there is his-and-hers watches dough sheet 20 when pressurizeing, protuberance by conquassation by the probability that perforate 21 is closed, but, when being formed perforate 21 by fluid jet, can not protuberance be formed, this unfavorable condition can be prevented in advance.
In addition, perforate 21 also can be formed with the fabric (web) forming surface patch 20 and side by side be formed, and also can be formed after formation of fabrics.In the present embodiment, although employ cotton water thorn formula fabric nonwoven cloth as surface patch 20, also can with cotton fiber is mechanically interweaved form fabric side by side on fabric, to form perforate 21 by fluid jet.Perforate 21 can be formed in the following manner: be placed on be formed along on the sheet material supporting mass of multiple protuberances that direction is spaced at intervals in length and breadth by forming the fabric of surface patch 20, and sheet material supporting mass from the face side direction relative with sheet material supporting mass of fabric and spray columnar fluid, form perforate 21 thus.In this case, the fiber of the part corresponding with protuberance moves to the periphery of this protuberance, again arranges (or orientation again) thus and forms perforate 21.Sheet material supporting mass such as can use be formed with protuberance roller, knitmesh or grid (mesh) etc.As knitmesh or grid, multiple wire rod plain weave can be used and mutually report to the leadship after accomplishing a task and there is this intersection point (joint portion) i.e. material of protuberance.
Melt-coating part 72 longitudinally Y and horizontal X is formed multiple at spaced intervals, thereby, it is possible to prevent from being formed with the surface patch 20 of these melt-coating parts 72 and lateral plate 60 ruptures.By forming melt-coating part 72, the intensity of surface patch 20 and lateral plate 60 is likely made to reduce, when longitudinally Y or horizontal X is formed this melt-coating part 72 continuously, there is the probability that surface patch 20 or lateral plate 60 rupture along these melt-coating parts, but, by by melt-coating part 72 longitudinally Y and be spaced laterally apart compartment of terrain formed, this fracture can be prevented in advance.
In the present embodiment, surface patch 20 is formed by cotton fiber, as long as but fiber at least containing the non-hot melt property fiber such as natural fiber.As non-hot melt property fiber, except cotton fiber, such as, staple fibre etc. can also be used.In addition, in surface patch 20, as long as the material containing about more than 50%, preferably approximately more than 67% non-hot melt property fiber.This is because, if not the amount of hot melt property fiber tails off, be then difficult to play its characteristic in surface patch 20.
Perforate 21 is ellipses that the size of longitudinal Y is larger than the size of horizontal X, but, also can be the almost equal circle of the size of longitudinal Y and horizontal X or rectangle.As long as lateral plate 60 and hot melt property sheet 50 can be made to engage via perforate 21, this size, shape can suitably change.
Hot melt property sheet 50 and lateral plate 60 are containing congener thermoplastic resin.Therefore, these sheet materials 50,60 are easy to mutual deposition by heating.In addition, wish when being formed hot melt property sheet 50 and lateral plate 60 by sheath-core type conjugate fiber, the resin being arranged in the surface (sheath) of its fiber is consistent at two sheet materials 50,60.In addition, when using sheath-core type conjugate fiber in this wise, only can be made surface (sheath) melting Bu Shi center (core) melting of its fiber by heating, therefore, it is possible to prevent the cut-out of the fiber caused because of heating.
