Definitions
- the present invention relates to an interlabial pad that can be used in conjunction with a female labia, particularly to be used in combination with a sanitary napkin, and a package in which the interlabial pad is individually enclosed in a packaging container.
- Related technology can be used in conjunction with a female labia, particularly to be used in combination with a sanitary napkin, and a package in which the interlabial pad is individually enclosed in a packaging container.
- sanitary napkins and tampon have been generally used as feminine hygiene products.
- napkins are used in contact with clothing, and due to poor adhesion to the vicinity of the vaginal opening, menstrual blood tends to leak from the gap with the body.
- menstrual blood tends to leak from the gap with the body.
- due to the attributes of the article there is a problem that foreign matter sensation or discomfort is likely to occur when the article is worn, and it is difficult to wear the article in the vagina.
- the interlabial pad which is located between the napkin and the tampon, has recently attracted attention.
- This interlabial pad is designed to be inserted into a woman's labia with a part of the pad interposed between the labia and abut on the labia.It is smaller than sanitary napkins, so it is more comfortable to wear and comfortable. In addition, it has the advantage of being sanitary and clean because of the limited range of soiling the body with menstrual blood. In addition, since it has higher adhesion to the body than a sanitary napkin, it is less likely to leak, and the heart when worn compared to a tampon inserted into the vagina. It has the characteristic of low physical resistance.
- the conventional interlabial pad had a problem in that the menstrual blood flowed down the pad surface before the menstrual blood was absorbed by the absorber, which could cause leakage. This is because menstrual blood flowing out along the labia inner wall has a slow flow rate and high wettability with the labia inner wall, so it does not flow out gradually from the labia ⁇ , but after a large amount of menstrual blood stays in the labia This is to run down at one time.
- the interlabial pad 24 shown in FIG. 2 has a knob portion 24a on the clothing side of the pad, and the wearer grips the knob portion 24a with his / her finger. Except for the force S (W099 / 56669), which makes it easy to mount the pad, and the pressing force from the finger except for the vicinity of the knob 24a, It is difficult to apply the pad between the labia, and poor adhesion between the pad and the inner wall of the labia. Therefore, menstrual blood may flow down the surface of the pad before being absorbed by the absorber, resulting in leakage of menstrual blood.
- the interlabial pad 34 shown in FIG. 3 can form a convex portion by bending the rear region 34 b of the pad along a substantially central line 36 in the longitudinal direction of the pad. It is something.
- the interlabial pad 34 can be used with the convex part sandwiched between the labia, and the adhesion between the pad and the inner labia wall is improved as compared with the interlabial pad 24 shown in FIG. You.
- menstrual blood tends to flow down on the pad surface, and menstrual blood may leak.
- the interlabial pad is smaller in size than a sanitary napkin, and the damage caused by menstrual leakage may be severe. Disclosure of the invention
- the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an interlabial space capable of rapidly transferring menstrual blood flowing down the inner wall of the labia to an absorber. To provide pads.

- the interlabial pad, wherein the band-shaped absorption regions arranged on both side portions of the portion form an inner labial inner wall contact region that comes into contact with a wearer's inner labial wall.
- the interlabial pad of the present invention is, for example, as shown in FIG. 4 (a), an absorbing sheet portion and a support sheet lining the absorbing sheet portion. 4 2 and
- the absorption sheet portion contains an absorber that absorbs body fluids such as menstrual blood, and is used so as to face the body when worn.
- the absorption sheet part is composed of independent absorbers 4
- a plurality of (three in the illustrated example) strip-shaped absorption regions each having a strip shape having 3 a and 43 b are formed as an aggregate in parallel.
- the band-shaped absorption region arranged at the center of the absorption sheet portion is the vaginal opening of the wearer.
- the band-shaped absorption regions arranged on both sides of the absorption sheet portion are arranged in contact with the inner wall of the wearer's labia.
- the body fluid outlet for example, the vaginal opening contact area 44a is formed.
- the labia inner wall contact area 44b is brought into close contact with the inner wall of the labia. Therefore, the vaginal orifice contact area 44a, which is in close contact with the deep labia including the vicinity of the vaginal orifice, primarily absorbs most of the menstrual blood excreted from the vaginal orifice, and at the same time produces a large amount of menstrual blood.
- vaginal opening contact area 44a and the labia inner wall contact area 44b combine to quickly transfer a large amount of menstrual blood flowing down the labia inner wall to the absorber at once. This is possible.
- the vaginal orifice contact area 44a and the labia inner wall contact area 44b have absorbers 43a and 43b, respectively, independently contained in the coated sheets 41a and 41b. Since it is easy to bend between the band-shaped absorbers, shape followability is good, and shape conformity (fitness) in the labia is improved. I do.
- the side edge of the labia inner wall contact area is formed in an arc shape, and both edges of the arc converge toward the longitudinal edge of the bodily fluid outlet contact area.
- the overall shape of the interlabial pad of the present invention is not particularly limited as long as it is a shape suitable for engaging with the labia, and examples thereof include an elliptical shape, an egg shape, a sputum shape, and a constriction shape. Shape.

- the vaginal orifice contact region and the labia inner wall contact region may be further divided into a plurality.
- the vaginal orifice contact area 44 a is divided into a plurality (three in the illustrated example) and provided, or as shown in FIG. b can be divided into a plurality (two in the example shown, two on each side).
- both the vaginal opening contact region and the labia inner wall contact region may be divided and provided in plurals.
- Such a shape is preferable in that the shape conformity (fitness) in the labia is further improved as compared with a case where each region is not divided.
- each absorber absorbs menstrual blood suitable for the location, thereby achieving efficient absorption.
- the interlabial pad of the present invention is not limited to the embodiment in which the vaginal opening contact region and the labia inner wall contact region are provided adjacent to each other, and a groove is provided between the vaginal opening contact region and the labia inner wall contact region. You may. For example, as shown in FIG. 8, a groove 50 is formed by leaving an interval of 1 to 5 mm between the vaginal opening contact area 44a and the labia inner wall contact area 44b. be able to.
- a water-permeable or water-absorbable internal sheet is interposed between the clothes-side surface of the absorbent sheet portion and the body-side surface of the support sheet.
- the absorption sheet portions that is, the covering sheets 41a and 41b and the absorbers 43a and 43b
- Clothes side and body side of support sheet 42 It is preferable to interpose a water-permeable or water-absorbable internal sheet 51 between the surface and the surface.
- a large amount of menstrual blood exceeding the absorption capacity of the vaginal opening contact area 44a which primarily absorbs menstrual blood excreted from the vaginal opening, was excreted. Even in this case, the menstrual blood passes through the inside of the inner sheet 51 and quickly moves to the labia inner wall contact area 44b. Therefore, it is possible to cope with high-speed and large amounts of menstrual blood.
- the fibers constituting the inner sheet 51 are oriented in the short direction of the interlabial pad 44, the absorbed menstrual blood can easily move in the orientation direction of the fiber layer, that is, in the lateral direction of the body. This is more preferable because menstrual blood can be promptly transferred from the vaginal opening contact area 44a to the labia inner wall contact area 44b.
- the interlabial pad of the present invention may be provided with a mini piece 52 for forming a finger insertion port 53 as shown in FIG. it can.
- the mini-sheet piece 52 is located at one of the two sleeves of the mini-sheet piece 52 in the lateral direction of the support sheet 42. At least one of the sleeves is not joined to the surface of the sabot seat 42.
- a cuff is formed between one of the sleeves of the non-bonded miniature sheet 52 and the support sheet 42, and the cuff serves as a finger insertion port 53 into which a finger can be inserted.
- the mini-sheet pieces 52 are joined only on the left and right sides of the support sheet 42, and the inside is not joined (adhered). For this reason, the mystical piece 52 is mounted so as to extend from one side of the support sheet 42 to the other side, and from the one side to the other side.
- a penetrating or non-penetrating space (a finger input space) is formed in a portion straddling the side portion of the device. In such a space, it is possible to insert and hold a finger.
- the finger width j means that it is not the thickness of the finger, specifically, the width of the finger in the direction in which the nail spreads. "Means an opening that is large enough to allow a finger to be inserted.
- the “directly secured opening of the finger width” in the direction of the support sheet surface means that when the finger is naturally inserted into the pad to attach the pad (when the belly of the finger is Means that the pad itself is primarily shaped to be suitable for finger insertion (when inserted directly into the clothing sheet surface of the support sheet). . For this reason, the wearer rotates the finger after inserting the finger, so that a finger-width opening can be secured in the surface direction. It will be excluded if a finger width opening is formed.
- the pad is inserted into the fingertip by inserting the finger into the finger inlet.
- the finger insertion opening is formed so as to have an opening of the wearer's finger width, the flat fingertip does not face the support sheet in a different direction. You will naturally be introduced to contact the support sheet.
- the finger insertion opening has a wide shape in the surface direction of the support sheet according to the shape of the wearer's fingertip, so that the wearer's finger insertion direction is determined, and the wearer inserts the fingertip on the fingertip. It can encourage the wearer to detect the event. As a result, even if it is worn between the labia, which is difficult to see, it is possible to wear the pad at an appropriate position while accurately grasping the correct mounting point. .
- the “side portion” in the longitudinal direction of the support sheet includes not only the peripheral portion of the pad but also the vicinity of the peripheral portion to which the miniature sheet can be joined.
- the interlabial pad of the present invention is composed of an absorbent sheet portion (that is, a covered sheet 41a, 41b and an absorbent member 43a, 43b). ) Is a bent portion 4 4c formed along the approximate centerline 46 in the longitudinal direction of the interlabial pad 44 in the body-side direction, and a hem continuous from both ends of the bent portion 4 4c. It is preferable that the miniature sheet 52 is composed of a portion 44d and a miniature sheet 52 joined to the garment side of the bottom portion 44d. With the above-described structure, the vaginal opening contact area 44a is shaded.
- the entire shape of the interlabial pad 44 becomes a shape in which the pinching force of the labia can easily act. Therefore, it is possible to provide the wearer with good adhesion and a feeling of wearing.
- the interlabial pad 44 can be reliably guided toward the labia that is difficult to see, which contributes to facilitating its mounting.
- At least the absorbing sheet portions are formed in a mountain-fold shape.
- the support sheet 42 is also formed in a mountain-fold shape, as a matter of course, within the scope of the present invention.
- interlabial pad according to any one of (1) to (7) above, which is an interlabial pad for use with a sanitary napkin used in combination with a sanitary napkin.
- sanitary napkins Some users of sanitary napkins (hereafter simply referred to as “napkins”) will use several of them when the amount of menstrual blood is large. However, there was a problem that the pad was not easily sensed from outside the clothes, and the presence of the pad was easily detected (conspicuous). In addition, the napkin was laid over areas other than the vagina where it was not necessary to use the napkin, causing rash and stuffiness. However, by using a pad and a napkin together, the sanitary products can be stacked only in the vicinity of the vagina, so that the above problem can be avoided. Furthermore, since only the pad can be replaced without replacing the napkin, the wearer does not have to carry a napkin of a size that is easily visible. (9) The interlabial pad according to any one of the above (1) to (8), wherein the interlabial pad is an interlabial pad for urinary incontinence.
- the interlabial pad according to the present invention can be used as an absorbent pad for urinary incontinence. That is, since the vaginal opening for discharging menstrual blood and the urethral opening for discharging urine are both located between the labia, when the interlabial pad according to the present invention is used by being sandwiched between the labia. It can absorb urine.
- urine can be absorbed between the labia, particularly near the urethral opening, so that an effective absorption pad can be obtained for urinary incontinence, especially for mild urinary incontinence.
- interlabial pad according to any of (1) to (8) above, wherein the interlabial pad is an interlabial pad for absorbing toys.
- the interlabial pad can be used for absorbing an object. That is, since the interlabial pad according to the present invention is sandwiched between the labia and used, it can also absorb secretions other than menstrual blood from the vaginal opening. It can also be used for this purpose (for absorbing torture).
- the present invention since it is possible to absorb discomfort and reduce the discomfort of the wearer, the present invention is also effective for the wearer during periods other than menstruation.
- Sanitary napkins are sold here for menstrual absorption Not only napkins, but also absorbent sheets may be included.
- interlabial pads When the interlabial pads are individually wrapped, it is possible to carry the pads one by one (per individual wrapping). Such a configuration facilitates easy carrying while keeping the pads clean and contributes to easy handling as compared to a case where a plurality of pads are enclosed in one packaging container.
- the interlabial pad according to any of (6) to (10) above which is a package enclosed in a packaging container for individual packaging having an opening.
- the package is enclosed in the packaging container such that the finger insertion opening is opened toward the opening opening.
- the finger opening is opened toward the opening means that when the package 54 is opened, the miniature piece 52 2 is inserted into the opening. This means that the finger entry port 53 formed thereby is exposed and contained so that a finger can be inserted into the finger entry port 53 immediately.
- the package 54 shown in FIGS. 13 and 14 is opened by pulling the tab tape 55 attached to the upper surface side of the packaging container 56 toward the right side of the drawing.
- the finger insertion port 53 is exposed at the opening, and opens toward the opening. Therefore, the wearer can immediately insert the finger into the finger inlet 53.
- the packaging container such that the interlabial pad is formed so that the miniscule pieces are mountain-folded toward the clothing side along a substantially central line in the longitudinal direction of the interlabial pad.
- the phrase “to form a mountain fold in the direction of the garment” means that the garment is completely bent with the garment side protruding, as shown in FIG. This also includes the case where the side is convex and curved. Since the interlabial pad 44 is enclosed in the packaging container 66 in this way, the folded finger insertion opening 53 when the packaging container 66 is opened opens naturally. The wearer can easily grasp the place where the finger is to be inserted, and the wearing of the pad can be made quicker and simpler.
- the mini-sheet pieces have a “folding shape”, and the entire pad does not need to have a “folding shape”. Therefore, for example, as shown in FIG. 15, as shown in FIG. 16, in addition to the package 64 in which the entire interlabial pad 44 is folded in a “mountain-fold shape” and contained in the packaging container 66, as shown in FIG. As shown in the figure, only the sheet 52 is made into a “mountain-fold shape”, while the main part of the interlabial pad 44 is folded in a valley-fold shape toward the clothes. It may be a package 74 contained in a packaging container 66.
- the type of opening of the packaging container is not particularly limited. As shown in FIGS. 15 and 16, in addition to the packaging container 66 which is cut off at the upper end and opened, as shown in FIG. As shown, a packaging container 86 that can be opened from the upper end to the left and right sides (so-called double door opening type) may be used.
