System.Then, sanitary napkin 1 and package panel 60 are integrally folded along.In the present embodiment, it is being arranged in longitudinal rule
At 1st folding line F1 of fixed position and the 2nd folding line F2, by sanitary napkin 1 (and package panel 60) three folding along longitudinal direction.First the 1st
At folding line F1 sanitary napkin 1 is folded along in such a way that skin-side surface becomes inside.Then, at the 2nd folding line F2, equally with
The mode that skin-side surface becomes inside is folded along sanitary napkin 1.Then, using well known to ultrasonic fusing and thermal welding etc.
Encapsulating method makes the cross side both ends of package panel 60 engage along longitudinal direction.Finally, fixation adhesive tape 61 is pasted to the cross of package panel 60
To central portion.Fixation adhesive tape 61 is pasted onto in a manner of it can remove on the outer surface of package panel 60, is inhibited as a result, using health
Package panel 60 is removed before towel 1, or the package body of sanitary napkin 1 is unfolded.In this way, forming such compact form shown in Fig. 3 B
Package body.
When user uses sanitary napkin 1, the sanitary napkin 1 of folding is unfolded according to step contrary to the above.Also, from
Sanitary napkin 1 removes package panel 60, and the adhesive surface 31A of exposing is pasted on underwear, is defended to be worn in a manner of it will not misplace
Raw towel 1.
In addition, due in individual packaging sanitary napkin 1, flank 50 is folded into laterally inboard (with reference to Fig. 3 A), so shape
At on flank 50 cool feeling region CR and a part for the skin-side surface of absorber 10 it is be overlapped in a thickness direction.Also,
In the part of the overlapping, the ingredient of the cool feeling agent of cool feeling region CR is transferred to 10 side of absorber and is attached to absorber 10 sometimes
In the skin-side surface of (upper sheet 20).When the ingredient of cool feeling agent is attached on absorber 10, cool feeling agent directly act on
The skin for the user that the absorber abuts forms strong impulse, may apply sense of discomfort to user.In contrast,
On the sanitary napkin 1 of present embodiment, defined area is limited in by cool feeling region CR is overlapping on the thickness direction of absorber 10
Domain, to be not easy to apply sense of discomfort to user.Illustrate this point below.
Fig. 4 is the vertical view of the sanitary napkin 1 for the state that flank 50 is folded into laterally inboard.Fig. 5 is to indicate Fig. 4
The sections C-C figure.In addition, in Fig. 4, for the cool feeling region CR and bending part 110 and hole portion of the flank 50 of doubling poststack
120 position relationship illustrates, also the bending part 110 of the part indicated by the solid line that is actually hidden in flank 50 and can't see
And hole portion 120.
As shown in Figure 4 and 5, in the state that flank 50 is folded into laterally inboard, cool feeling region CR (the moon of Fig. 4
Shadow portion) it configures in the both lateral sides portion of absorber 10.Specifically, cool feeling region CR be configured in a thickness direction not with absorption
The position of the middle section overlapping comprising lateral center line of body 10.In particular, region is abutted in introitus, on absorber 10
The position Chong Die with the region being clipped in 1 between of bending part 110 does not configure cool feeling region CR to through-thickness.As described above, being clipped in 1
Region (region of the lateral center of absorber 10) between bending part 110 is when using sanitary napkin 1 and the skin of user
The region of abutting.Thus, by keeping the region not be overlapped in a thickness direction with cool feeling region CR, cool feeling region CR can be inhibited
The ingredient of cool feeling agent be transferred to the region being clipped between 1 pair of bending part 110 of absorber 10.It is not easy to apply user as a result,
Add sense of discomfort.In particular, it is the part being in direct contact with the introitus of user that introitus shown in Fig. 4, which abuts region, so
It is not weighed in a thickness direction with cool feeling region CR by making the introitus in the region being clipped in 1 between of bending part 110 abut region
It is folded, the stimulation generated by cool feeling agent can be inhibited in the vagina oral area of user.
In addition, the region on rear side of the longitudinal direction of sanitary napkin 1, configures the cool feeling region CR's on stern alar part 52 after folding
A part is Chong Die with the region being clipped in 1 between of bending part 110.But since the region is when using sanitary napkin 1 and user
Buttocks abut region, so with introitus abut region compared with, even if if the stimulation generated by cool feeling agent is acted on not
Sense of discomfort easily is applied to user.On the contrary, in buttocks side, because stern alar part 52 covers vast region, it is bored to be easy to happen heat, so
Even if the ingredient of cool feeling agent is transferred to the region for the part for absorbing side, it is also easy to give user's refrigerant sense, rather than to making
User applies sense of discomfort.Thus, the region on rear side of the longitudinal direction of sanitary napkin 1, even if the cool feeling region CR of stern alar part 52 and being clipped in 1
The part overlapping in the region between bending part 110, is not easy to produce problem.
In addition, cool feeling region CR is formed as not Chong Die (with reference to figure for the bending line 50f of the basic point of bending with flank 50
4).That is, when flank 50 is folded into laterally inboard, cool feeling region CR itself will not be bent over.In present embodiment
In, so that granular cool feeling agent is engaged with the defined region of upper sheet 20 by using bonding agent, forms cool feeling region CR.If
If cool feeling region CR is Chong Die with bending line 50f, because of the influence of the stress that is generated when bending etc., may make in the part of the overlapping
The quality of cool feeling agent particle changes.Such as it is generally acknowledged that：Stress when because of bending is acted on, and keeps the core of cool feeling agent i.e. clear
Cool dose is exposed to external and volatilizees, and when using sanitary napkin 1, no longer can give user's refrigerant sense etc. in the part.Relative to
This, in the cool feeling region CR of present embodiment, the stress etc. generated by bending will not be acted on, so cool feeling region CR's
In whole region, it is easy to remaining cool feeling agent into the state of homogeneous.
In addition, when using sanitary napkin 1, along bending line 50f to non-skin side fold-back flap portion 51, it is being formed with the flap
The region (that is, introitus abutting region) in portion 51, bending line 50f are to be abutted (near thigh root) with the pars inguinalis of user
State.At this point, when cool feeling region CR is Chong Die with bending line 50f, the pars inguinalis of user is applied by cool along bending line 50f
Feel the stimulation that agent generates, user is made to generate sense of discomfort sometimes.But in the present embodiment, it is being formed with flap portion 51
Region, bending line 50f and cool feeling region CR through-thickness be not also be overlapped, so being not easy that user is made to generate above-mentioned such abdomen
The sense of discomfort in butt crack portion.
In addition, as shown in Figure 4 and 5, in the state that flank 50 is folded into laterally inboard, cool feeling region CR is at least
It is sandwiched by 30 through-thickness of backsheet.In other words, all of the cool feeling region CR coated with cool feeling agent are partially in configuration and exist
The state of part between the thickness direction of backsheet 30.Since backsheet 30 is made of resin film etc., so even if rolling over
The particle of cool feeling agent in the state of flank 50 is folded departing from cool feeling region CR, the particle for being not easy to produce the cool feeling agent passes through the back of the body
Portion's piece 30 and the problem for escaping to the outside of sanitary napkin 1 etc..In addition, in the present embodiment, due in cool feeling region CR and the back of the body
Reinforced sheet 55 is provided between portion's piece 30, so being easy to that the particle of cool feeling agent is inhibited to escape to outside.
In addition, as shown in figure 5, in the state that flank 50 is folded into laterally inboard, at least one of cool feeling region CR
Divide Chong Die with folding of Ω shape region 20fr through-thickness.As described above, by making 20 through-thickness of upper sheet stack by shape
At folding of Ω shape region 20fr, so in folding of Ω shape region 20fr, other areas of the thickness of thickness direction than upper sheet 20
Domain height (thickening).Thus, when folded side panel 50, cool feeling region CR is first in the position opposite with folding of Ω shape region 20fr
Relationship.Thus, even if the transfer of the ingredient of the cool feeling agent from cool feeling region CR to absorber 10 has occurred, it is also easy to make the cool feeling
The ingredient of agent is preferentially transferred to folding of Ω shape region 20fr.By making the transfer of cool feeling agent in the transverse ends portion of absorber 10
Area preference occurs, cool feeling agent be not easy to be transferred to absorber 10 be clipped in 1 between of bending part 110 region.It can use as a result,
When sanitary napkin 1, it is less susceptible to apply sense of discomfort to user.
