Description

Method for preventing back flow of body fluids and plastic support for this, body fluid absorbing articles and panties

The present invention relates to a method for preventing back flow of body fluids and a plastic support, body fluid absorbing article and panties for the purpose, and in particular, a panty having a plastic core material or a contraction portion induces flexion in a body fluid absorbing article to induce bending of the buttocks. It relates to a method for preventing the body fluid from flowing to the back by filling a part of the gluteal sulcus, and a plastic support for this, a body fluid absorbing article, and panties.

In general, women of childbearing age undergo periodic menstruation on average once a month. During the menstrual period, women feel a lot of discomfort, but the most uncomfortable is the anxiety of leaking menstrual blood.

Since Kimberly's disposable sanitary napkin cortex was developed in 1920, the sanitary napkin has evolved a lot. Products that have added a polymer absorbent for rapid absorption of menstrual blood, have wings on the side to prevent the menstrual blood from leaking to the side, and have multiple leakage prevention lines have already been generalized to the present day. However, these sanitary napkins for preventing leakage are insufficient to block menstrual blood flowing to the buttocks, and there are still no sanitary napkins capable of directly blocking menstrual blood flowing through the buttocks and furrows at bedtime.

In general, since the sanitary napkin has a planar shape, when the sanitary napkin is worn, a space is created between the sanitary napkin and the hip furrow, and menstrual blood leaks frequently through this space. This flow of menstrual blood cannot be absorbed by the sanitary napkin and can flow to the back and contaminate clothes or blankets. This is especially true when lying or sleeping, and a means to block and absorb menstrual blood leaking along the buttocks furrows is required. When sleeping, a so-called overnight or panty type is also worn, but it is not a basic blockage of menstrual blood flowing to the buttocks, but a large oversized sanitary napkin. In other words, when using overnight or panty-type, the menstrual blood that has flowed out of the buttocks furrow may be absorbed from the wide absorbent section and not leak out of the sanitary napkin. Is unsanitary. Also, the price is higher than that of a normal sanitary napkin.

Therefore, in order to block menstrual blood flowing to the buttocks, it is necessary to fundamentally block menstrual blood so that it does not pass through the buttocks.

In accordance with this need, sanitary napkins with protruding menstrual blood absorbers attached to the buttocks are disclosed in Korean Utility Model Applications Nos. 20-2001-0025132, 20-2003-0002367 and 20-2003-0016829. However, such a protruding absorbing portion is meaningful in that it can fill the space between the sanitary napkin and the hip furrow, but it does not correspond to the shape of a flexible hip. For example, the shape of the buttocks is deformed when standing or lying down, or when sitting, especially when sitting on a chair, so that the buttocks are pressed and the hip furrows become shallow. Therefore, it is obvious that the projected absorbent portion as a fixed shape is very inconvenient when changing the posture. In addition, when the sanitary napkin includes a protruding absorbent portion, it becomes a three-dimensional shape, so considering the difficulty in slim packaging for carrying, such as a thicker packaging thickness, industrial applicability is rare.

As such, a method of effectively blocking menstrual blood flowing to the buttocks is an essential task to be solved among the functions of the sanitary napkin, but there are no sanitary napkins that have fundamentally solved this.

On the other hand, since the sanitary napkin is generally used by attaching it to the panties, in order to effectively block menstrual blood flowing to the buttocks, it is necessary to improve the adhesiveness of the buttocks of the panties as well as the sanitary napkin itself.

Furthermore, this situation may occur in the same way for various body fluids such as urine, blood, lymph fluid, pus, as well as menstrual blood. In particular, in the modern age, when the elderly who have to spend a long time in bed are increasing due to the increase in the average lifespan, the sales volume of adult diapers is rapidly increasing. Therefore, it is urgent to develop a technology to prevent the back body fluid flow through the buttocks.

The reason for the space between the sanitary napkin and the buttocks furrow is that it is difficult to adhere the planar sanitary napkin to the curved surface of the buttocks. That is, in order to block the menstrual blood flowing into the buttocks furrow, an absorbent part (hereinafter referred to as a 'buttocks insertion part'), which is inserted into the buttocks, is required, and in order to do so, stereoscopic sanitary napkin is considered.

Accordingly, in the present invention, as the hip insertion portion, the sanitary napkin itself was changed instead of the protruding absorption portion to form the hip insertion portion.

In addition, since the sanitary napkin is generally attached to the panty, if the panty is configured to be in close contact with the hip furrow along with the buttock insertion portion of the sanitary napkin, menstrual blood may be more effectively blocked from flowing into the hip furrow.

For example, in the case of an oversized size that covers the buttocks 10 broadly, such as an oversized or overnight of 28 cm, it is preferable to attach two or more plastic supports 100, for example, in the case of two, both sides of the anus and coccyx It is desirable to position them so that they cross each other.

For example, FIG. 8 shows a case where one plastic support 100 is coupled, and FIG. 9 shows a case where two plastic supports 100 are coupled adjacent to each other. By providing a plurality of the plastic support 100 as described above, the curvature induced by the plastic support 100 is stably implemented in the body fluid absorbing article 200, thereby completely blocking the flow of body fluid from the buttocks furrow 12 to the back. .

The variable body fluid absorbing article 200 may be used in a three-dimensional form by generating a buttocks insertion portion using a plastic support 100 to prevent the back flow of body fluid, but can also be used in the same plane as the general body fluid absorbing article 200 Do. When used to prevent the back flow of body fluids, the part of the plastic support 100 mounted across the gluteal furrow 12 counterpart of the body fluid absorbing article 200 is pressed between the buttocks furrow 12 by pressing with a finger or the like. The buttocks insertion portion can be formed by closely contacting with (10).

Since the plastic support 100 mounted on the variable body fluid absorbing article 200 has a property of flexibly deforming, when the depth of the buttocks furrow 12 is changed by changing the posture, for example, sitting in a chair, etc. in FIG. 16, FIG. 17 Even when the buttocks 10 are pressed, it assists the fluid absorbing article 200 to be variably adhered to the fluid buttocks 10.

On the other hand, when the variable body fluid absorbent article 200 is attached to a general panty, when the buttocks insert portion of the body fluid absorbent article 200 is inserted into the buttocks 10 while being adhered to the panty, in the buttocks furrow 12 together with the panties Since it can be easily removed, it is preferable that the buttocks insert is not adhered to the panties in order to stably adhere and fix the bodily fluid absorbing article 200 to the buttocks 12. That is, while the outer side (adhesive portion) of the body fluid absorbing article 200 is attached to the panty, the front side of the body fluid absorbent article 200 (upwards in FIGS. 4 to 9) centered on the plastic support 100, while the body fluid absorbent article ( It is preferable that the rear of the 200) (bottom in FIGS. 4 to 9) forms a buttocks insert independently of the panty. To this end, the adhesive portion of the buttocks insertion portion of the body fluid absorbing article 200 may be removed, or the adhesive portion may be covered with a separate member such as a cover 130 as shown in FIGS. 8 and 9.

On the other hand, in the case of the panty 300 having the contraction portion of the present invention to be described later, the body fluid absorbing article 200 is a panty ( 300) is more preferable. Therefore, in this case, unlike the case of the above-mentioned ordinary panties, there is no need to provide a cover on the plastic support.

In addition, the adhesive portion of the body fluid-absorbing article 200 covered by the cover 130 may be from a portion where the plastic core 110 is adhered to an end of the back portion of the body fluid-absorbing article 200 or half thereof. .

In addition, the plastic support 100 may be adhered to the body side, the outside, or the body side and the outside of the body fluid absorbing article 200. 11 shows a state in which the plastic support 100 is adhered to the outside of the body fluid absorbing article 200.

The firing support 100 is a bodily fluid absorbing article 200 so as to cross the buttocks furrow 12, preferably the buttocks furrow 12 between the urethra and coccyx, on the butt 10 contact side of the body fluid absorbing article 200. ) May be attached to the body side, the outside, or both. For example, in the case where the plastic support 100 is attached to the body side of the body fluid absorbing article 200, the plastic support 100 can fix the body fluid absorbing article 200 more tightly, and can even directly act as a barrier. It is suitable for overnight, but since it is a part that comes into direct contact with the skin, it may be restricted in material selection of the surface of the plastic support 100. On the other hand, the form in which the plastic support 100 is attached to the outside of the body fluid absorbing article 200 does not directly contact the skin, and thus is not particularly limited by material and is preferable. When the thickness of the body-absorbing article 200 is thick, it may be considered to attach to both the body side and the outside from the viewpoint of increasing the fixability.

The form of the calcined support 100 is 1 to 5, preferably 1 to 4, more preferably 1 to 3 calcined core 110 is coupled to the body fluid absorbent article 200 without or surrounding the outer shell It has a configuration having a coupling member 120 so as to allow, various types are possible depending on the type of body fluid absorbing article 200, the side to be attached. For example, in the case of a body fluid absorbing article 200 having no adhesive portion on the outside, such as a diaper or a panty-shaped sanitary napkin, or a cotton sanitary napkin, it may be in the form of FIG. 1, and the outside is a panty-attached body fluid absorbing article 200 having an adhesive portion. In the case of general panties, the shape of FIG. 2 or 3 is preferably provided with a cover 130 covering a wide portion so that the buttocks insertion portion is not attached to the panties, and in the panties 300 having the constricted portion according to the present invention, FIG. The form is preferred.

In addition, various applications are possible when the calcination support 100 is attached to a general sanitary napkin, for example, when used as an alternative to overnight, when lying down according to sleep habits, the calcination support 100 is the butt of the body fluid absorbing article 200 ( 10) By attaching to the front side as well as the front side and adhering properly, it is possible to prevent the body fluid from flowing forward.

The plastic support 100 is convenient to carry, and can be used by attaching it to a desired portion of the body fluid absorbing article 200, if necessary.

On the other hand, the panty 300 for preventing the back flow of bodily fluids of the present invention is characterized in that the contraction part 310 is formed in the corresponding area of the urethra or coccyx in the direction corresponding to the buttocks furrow 12. 14, it can be seen that the flexure was formed to correspond to the buttocks furrow 12 as the contracted portion was viewed from the side of the panties formed by the wrinkles.

In addition, the wrinkles may be formed by shirring wrinkles, gather wrinkles, dart wrinkles, poltz wrinkles, corrugated wrinkles, wrinkles by shrinkable or elastic bands, and combinations thereof. The shirring is a method of stitching a fabric to reduce wrinkles by squeezing, and a dart refers to a method of folding a certain portion (to fit a three-dimensional body) to reduce it. In FIG. 13, the top panties are wrinkles caused by an elastic band, the middle panties are shirring wrinkles, and the bottom panties are dart wrinkles.

In addition, the portion of the panty 300 on which the shrinking portion 310 is formed may be contracted to have a length of 80 to 40%, preferably 70 to 50%, compared to before the shrinking portion 310 is formed.

When the panty 300 is worn by the contraction part 310, a groove corresponding to the buttocks furrow 12 may be formed, and the groove serves to assist the body fluid absorbing article 200 to be in close contact with the buttocks furrow 12. , And may further include a non-stretchable band, an elastic band, or a core material. The core material may be included as a plastic core material of the present invention in a direction crossing the buttocks furrow.

And, the body fluid absorbing panty for preventing the back flow of body fluid of the present invention is characterized in that the plastic support 100 is coupled to the traverse of the buttocks furrows in the corresponding region of the urethra or coccyx among the panties.

In general, the sanitary panty used during menstruation is usually padded with a waterproof cloth to prevent bleeding of menstrual blood. Because the waterproof cloth is not elastic, the panties do not adhere well to the buttocks and are not well ventilated. Do. In addition, a waterproof cloth catches menstrual blood flowing to the buttocks at bedtime, but the menstrual blood may spread around the buttocks. On the contrary, the panty 300 having the contracted portion of the present invention forms a bend corresponding to the buttocks furrow, so that the body fluid absorbing article 200 can be well adhered to the buttocks furrow, so that the menstrual blood flows into the buttocks furrow 12 and may spread. low. You can use a waterproof cloth if necessary, but you can use it without using a waterproof cloth, and in this case, it is well ventilated and comfortable. The panty 300 in which the shrinking portion is formed not only enables the body fluid absorbing article 200 to be well adhered to the buttocks furrow, but also has the advantage of saving the buttocks line unlike general sanitary panties even when wearing under pants or the like. .

In order to achieve the object described above, the method for preventing the back flow of body fluids of the present invention is a part of the panty 300 in which the shrinking portion 310 is formed as described above, a plastic support, or a panty in which the shrinking portion 310 is formed. Part of the 300 and the plastic support 100,

By inducing the bending of the urethra to the coccyx side of the body fluid absorbing article 200,

The body fluid-absorbing article 200 is characterized by filling a portion of the buttocks furrow 12.

In addition, the firing support 100 may be coupled to the body fluid absorbing article 200 in a direction transverse to the buttocks furrow 12.

In addition, the contraction portion may be formed on the panty 300 in a direction corresponding to the buttocks furrow 12.

Hereinafter, examples of the present invention will be described.

[Model experiment of variable body fluid absorbing article according to the present invention]

Experiments were conducted in a model to show the principle of preventing the back flow of menstrual blood and the effect of the variable body fluid absorbing article according to the present invention, and the results are shown in FIGS. 15 to 17.

15 to 17, two boiled eggs were prepared to reproduce the buttocks, and FIGS. 16 and 17 inserted a plastic core material made of a soft iron core to cross the buttocks furrows on one side of the body fluid absorbing article. By doing so, the buttocks insertion portion by the body-absorbing article of the present invention was formed. Fig. 15 shows a general flat body fluid absorbent article without a plastic core inserted. The convex part of two boiled eggs is a model of both buttocks, and the space between them is a simulation of the buttocks furrow.

In the case of a general bodily fluid absorbing article, a space is created between the planar bodily fluid absorbing article and the buttocks furrow (FIG. 15), but in the bodily fluid absorbing article of the present invention, the buttocks insertion portion formed by the fired core is filled (FIG. 16). ). In addition, even when the buttocks insertion portion is pressed and the buttocks furrow becomes shallow, the plastic core may correspond to the shallow buttocks insertion portion (FIG. 17).

As can be seen from the results of FIGS. 16 and 17, the body fluid absorbing article of the present invention fills the space between the buttocks furrows by using a plastic core material such as a soft iron core to close the hip furrows, so that the menstrual blood does not pass through the hip furrows. It can be directly blocked, and can form a variable buttocks insertion portion corresponding to the shape of the flexible buttocks according to the posture.

[Implementation of a plastic support according to the present invention]

1 to 3 is an example of a plastic support according to the present invention, the shape of FIG. 1 without a separate cover in addition to the fired core, the shape of FIG. 2 with a cover, and finally a cut line formed in the cover 3 It shows the form of

The calcined core material fills the buttocks furrow by inducing a bend in the body fluid absorbing article, and the coupling member refers to an adhesive member or an adhesive member formed on the calcined core material or its outer shell to attach the calcined core material to a separate body fluid absorbing article or panty. The cover serves to cover the panty adhesive portion of the body-absorbing article so that the buttocks insert does not adhere to the panty when using normal panty. When attached to the panty having the shrinking portion according to the present invention, the plastic support need not include a cover separately as described above.

The horizontal length of the firing support of the present invention (horizontal length of FIGS. 1 to 3) is 4 to 15 cm, preferably 5 to 13 cm. The length of the plastic support without the cover (the length in the longitudinal direction of FIGS. 1 to 3) is 0.1 cm to 3 cm, preferably 0.2 cm to 2 cm, and when the cover is included, the body fluid absorbent article It can vary depending on the length. Specifically, in the case of a body fluid-absorbing article having a length of oversized or larger, two or more of them may be attached in succession to cover the adhesive portion of the panty.

The plastic support adheres to the outside (adhesive portion) of the body fluid absorbing article so as to cross between the urethra and the coccyx. When one is attached, it passes around the anus, such as from the center of the core portion of the body fluid absorbing article toward the buttocks. 3 cm to 10 cm, preferably 4 cm to 9 cm, more preferably 5 cm to 8 cm apart. On the other hand, when attaching the two, it is preferable to additionally attach the buttocks insertion portion to the buttocks stably so as to pass the anus and coccyx respectively, for example, about 4 cm to 5 cm away from the plastic core. In view of this, when two plastic supports are attached, it is appropriate that the length of the cover is 4 cm to 5 cm in order to attach one after another to cover the panty adhesive portion.

[Test Example]

In this embodiment, the plastic support example was prepared and attached to the outside (adhesive portion) of a commercially available sanitary napkin, to investigate the effect of the present invention.

A plastic support of a band type (length 1.5 cm) as shown in Fig. 1 and a cover type (length 4.5 cm and 6.5 cm) as shown in Fig. 2 or 3, wrapped around a soft iron core as a plastic core with a non-woven fabric as a shell, is produced. It was attached to various commercially available sanitary napkins, and the buttocks adhesion degree, buttocks variability and fit were tested. In order to examine the effect of the plastic support alone, general panties were first used.

1. Example of manufacturing and wearing a variable sanitary napkin with a plastic support (the present invention) attached (using general panties)

First, a variable sanitary napkin is manufactured by attaching one or two plastic supports of the present invention to various commercially available sanitary napkins. To cover the panty adhesive portion of the buttocks insertion portion, two types of cover types of 4.5 cm and 6.5 cm in length were attached in combination.

The first firing support was attached to the outside of the sanitary napkin (adhesive part) about 5 cm to 8 cm away from the center of the core portion of the sanitary napkin. When using one plastic support, for example, in the case of a medium of 24 cm, a cover of 4.5 cm in length is suitable, and in the case of a large of 26 cm, a cover of 6.5 cm in length is sufficient to sufficiently cover the panty adhesive part. It was appropriate. When two firing supports are required, a cover type of 4.5 cm in length is attached as the first firing support to pass the anus and coccyx, respectively, followed by a second appropriate firing support suitable for the length of the sanitary napkin.

Next, after attaching the variable sanitary napkin to the panty and wearing the panty, the plastic support was pressed into the anus and fixed by hand. When two plastic supports were attached, the second plastic support was pressed and fixed between the coccyx, and the buttocks insertion portion and the extended portion thereof were brought into close contact with the buttocks.

2. Comparison of buttock tightness of a flexible sanitary napkin with plastic support (using normal panties)

After pressing the heart portion of the plastic support and inserting it into the anus to fix it, the degree to which the formed buttock insertion portion was maintained was compared. The degree of adhesion of the sanitary napkin to the buttocks was evaluated by dividing it into 5 grades of low, poor, normal, good and excellent, and the results are shown in Table 1.

number	Sanitary napkin types	Type and number of plastic supports	Cover length	Buttocks adhesion
Contrast	Medium (24 cm)	-	-	lowness
Example 1	Medium (24 cm)	1 band type	-	usually
Example 2	Medium (24 cm)	1 cover type	4.5 cm	Good
Example 3	Large (26 cm)	1 cover type	6.5 cm	Good
Example 4	Extra large (28 cm)	1 cover type	4.5 cm	usually
Example 5	Extra large (28 cm)	2 cover	4.5 cm + 4.5 cm	Good
Example 6	Overnight (33 cm)	1 cover type	4.5 cm	usually
Example 7	Overnight (33 cm)	2 cover	4.5 cm + 6.5 cm	Good
Example 8	Panty (M)	1 band type	-	usually
Example 9	Panty (M)	2 band type	-	usually

In the case of Examples 2 and 3, which are medium and large, up to 26 cm, a butt insert was well maintained even with one cover-type plastic support. In these two cases, there was no part protruding behind the coccyx, so it was the best fit to the gluteal furrow. In the case of the oversized over 28 cm, when one cover-type plastic support was used, the sanitary napkin part protruding behind the coccyx protruded without sticking to the buttocks in a curved state (Examples 4 and 6), but the cover-type plastic support was applied to the coccyx part. When additionally attached, a portion of the sanitary napkin longer than the coccyx may adhere to the buttocks, thereby maintaining the buttocks insertion portions (Examples 5 and 7). As a result of this, it can be seen that when the length of the sanitary napkin is much longer than that of the coccyx portion, at least the plastic support is required around the anal region and the coccyx, respectively.

On the other hand, as in the case of Example 1 using a band-type plastic support, when the buttocks insertion portion is inserted into the buttocks furrows while being adhered to the panties, the buttocks insertion portion leaves the buttocks furrows together with the panties, or the buttocks insertion portions are separated from the panties Since the adhesive portions on both sides may adhere to each other and there is a possibility that it is no longer variably deformed, it can be seen that in the case of general panties, the buttocks insertion portion is preferably not attached to the panties.

In addition, in the case of the panty type sanitary napkin, unlike the panty attachment type, there is no adhesive portion on the outside of the sanitary napkin, so one or two band-type plastic supports were attached instead of the cover type (Examples 8 and 9). In the case of the panty type, since the buttocks insertion portion is structurally similar to the case in which the buttocks insertion portion is attached to the panties, the buttocks insertion portion is not maintained as independently as the panty attachment type, but the dorsal side in that the plastic support can block at least a portion of the buttocks furrow. It is believed that it can play a secondary role in preventing flow.

3. Production of sanitary napkins with fixed projecting absorbers (for comparison)

In order to compare the variability and fit with the variable sanitary napkin according to the present invention, a sanitary napkin having a protruding absorbent in the buttocks according to the prior art (hereinafter, also referred to as a 'protruding sanitary napkin') was prepared. Two medium-sized sanitary napkins were overlapped, and a protruding absorbent was made using the upper sanitary napkin, and the space between them was filled with cotton and fixed to produce a protruding sanitary napkin (Comparative Example 1).

4. Evaluation of variability and fit

Comparative Example 1 was prepared as a comparative example as described above, and variability and fit were compared with Example 2 of the present invention having the same size. After forming the buttocks insert, the glutes of the buttocks were shallow by the chair surface while repeating sitting and standing up on the chair, and the variability and fit of the buttocks inserts corresponding thereto were evaluated and the results are shown in Table 2. Since this evaluation should be done in a state in which the sanitary napkin is in close contact with the buttocks, the tight panties as possible are worn in order to increase the adhesion of the sanitary napkin to the buttocks. It should be understood that if the size is not oversized or oversized, the tightness of the buttocks may be deteriorated, so it is not a standard for this evaluation.

In the case of Example 2 according to the present invention, when the buttocks were pressed against the chair surface, the buttocks insertion portion was deformed to fit the buttocks furrows, and when it rose again, it was deformed to fit the buttocks furrows in close contact with the buttocks. Accordingly, the buttocks insertion portion was flexibly adhered to the buttocks furrow, so the fit was also good.

On the other hand, in the case of Comparative Example 1 having a fixed protruding absorbent, when it was worn, it adhered well to the buttocks, but when seated in a chair, the fixed protruding absorbent was pressed with the buttocks and squeezed the shallow buttocks furrow to feel a solid foreign body feeling. It was uncomfortable.

number	Sanitary napkin types	Variability	Fit
Example 2	Medium (24 cm) + plastic support	Variability. Due to the plastic support, the buttocks insertion part is deformed to fit the buttocks furrow.	The buttocks insertion part fits flexibly to fit the buttocks furrow.
Comparative Example 1	Medium (24 cm) + protruding absorbent	No variability. Fixed projecting absorbent part	When you sit down, you feel a strong discomfort and discomfort.

5. Fabrication of panty with contraction in the direction corresponding to the buttocks furrow (invention)

In order to produce a panty having a shrinking portion according to the present invention, about 9 cm in length was contracted to 5.5 cm from the back sewing line of the pad portion of the normal panty (control) to make a shrinking portion in a direction corresponding to the hip furrow. Example 10 having elastic wrinkles by shrinking the corresponding length using an elastic rubber band and Example 11 having non-stretch wrinkles using four dart wrinkles were prepared.

6. Comparison of hip adhesion of each sanitary napkin by panties according to the present invention

Plain panties, Example 10 or Example 11 was attached to a 24 cm medium-sized normal sanitary napkin or a sanitary napkin including a plastic support (band / cover type), and the butt adhesion of the sanitary napkin by each panty was compared. The degree of adhesion of the sanitary napkin to the buttocks by the panties was divided into 5 grades of low, poor, normal, good and excellent, and the results were shown in Table 3.

In the case of Examples 10 and 11 according to the present invention, it showed good butt adhesion to the general sanitary napkin as well as the sanitary napkin of the present invention (Test Example 4). The contraction portions corresponding to the buttocks of Examples 10 and 11 exhibited the same results for each sanitary napkin, both stretchable and non-stretchable (Test Examples 4-9). On the other hand, in the case of Example 10 and Example 11, unlike the case of the normal panties, both the band type and the cover type had excellent butt adhesion (Test Examples 5 and 6, or 8 and 9). In the case of ordinary panties, it is preferable to use a cover-type plastic support so that the buttocks insertion portion of the sanitary napkin is not attached to the panties, since the panties are not in contact with the buttocks furrows (see Table 2). Since the embodiment 11 is in a form in close contact with the buttocks furrow, a band type is sufficient without the need to use a cover-type plastic support, and the band type is rather preferable in that it can increase the fixing property of the sanitary napkin by widening the adhesive portion with the panties. Can be seen.

As a result, when using either the sanitary napkin of the present invention or the panties of the present invention, the buttocks adhesion was improved as compared to the case where it was not, and when the sanitary napkin of the present invention was used with the panties of the present invention, the buttocks adhesion of the sanitary napkin was improved. I could increase it further.

Test example	sanitary pad	panties	Buttocks adhesion
Test Example 1	Medium (control)	Plain panties (control)	lowness
Test Example 2	Example 1 (band type)	Plain panties (control)	usually
Test Example 3	Example 2 (cover type)	Plain panties (control)	Good
Test Example 4	Medium (control)	Example 10 (Stretchy contraction)	Good
Test Example 5	Example 1 (band type)	Example 10 (Stretchy contraction)	Great
Test Example 6	Example 2 (cover type)	Example 10 (Stretchy contraction)	Great
Test Example 7	Medium (control)	Example 11 (Non-stretchable contraction)	Good
Test Example 8	Example 1 (band type)	Example 11 (Non-stretchable contraction)	Great
Test Example 9	Example 2 (cover type)	Example 11 (Non-stretchable contraction)	Great

7. Dorsal flow blocking test of menstrual blood

The absorption pattern of menstrual blood was tested using the sanitary napkin of Example 2 and / or the panties of Example 10. Five subjects were surveyed.

To summarize the survey contents, first, the sanitary napkin of Example 2 was tested alone, that is, the sanitary napkin of Example 2 was tested with ordinary panties. It was evaluated that the fit was also satisfied. With respect to the variability and the buttock tightness, all were satisfied when the panties were tight, but the buttock inserts may come out when the panties were not seated, so that the buttock tightness was slightly deteriorated. On the other hand, when the same subject who evaluated that the buttocks adhesion was slightly inferior was used together with the panties of Example 10, the buttocks adhesion was also evaluated as very satisfactory.

In the sole evaluation of the panty of Example 10, it was evaluated that the sanitary napkin can be well fixed to the buttocks by the contraction portion corresponding to the hip furrow, although the hip insertion portion is not formed as in the sanitary napkin of Example 2.

Regarding the effect of blocking the dorsal flow of menstrual blood, in the case of using the sanitary napkin of Example 2, all subjects evaluated that there was no dorsal flow of menstrual blood even when wearing the normal panties. It was evaluated as comfortable and hygienic because there was no menstrual blood around the buttocks.
