Description

[Detailed explanation of the idea] The present invention relates to a breast leakage receiving pad.

Conventional breast leakage pads used by breastfeeding women all have an absorbent material such as absorbent paper as the middle layer, and the inner layer is covered with an absorbent material such as absorbent paper. It is a bowl-shaped body having a liquid-impermeable membrane on both or at least the outer layer. Of course, the breast milk absorbed by the absorbent material,
This is to prevent leakage to the outside, which is the clothing side, or to the inside, which is the skin side. However, with this structure, the breasts become stuffy and uncomfortable while being worn. Furthermore, when the liquid-impermeable membrane is made of synthetic resin film or waterproof paper and is exposed to the outside or comes into contact with the skin, the appearance is poor or the feel is poor when worn.

The present invention provides a pad that overcomes the drawbacks of the conventional products, and will now be described with reference to the accompanying drawings. That is, in the present invention, the outer layer 1
and an inner layer 3, the absorbent material 2 is interposed between the bowl-shaped body, and the outer layer 1 is a laminate material with a polyethylene film 1a on the inside and a rayon paper 1b on the outside, and the inner layer 3 is a , is a laminate material with a water-permeable nonwoven fabric 3a on the inside and a polyethylene membrane 3b on the outside, and a nipple insertion hole 7 for fitting the nipple is formed at the center of the inner layer 3. In the upper half region of the inner layer 3 above the polyethylene film 3b, ventilation holes 4 having a smaller diameter than the nipple insertion holes 7 are scattered and formed. Polyethylene is adhered to the nonwoven fabric 3a as a glue 5,
The entire periphery of the outer polyethylene film 1a and the inner polyethylene film 3b are heat-sealed and adhered to each other by thermal melting, making this a milk leakage receiving pad.

When referring to the inside and outside, the side that comes into contact with the human body when worn and used is called the inside, and the side that comes into contact with clothing is called the outside.

The inner side of the outer layer 1 according to the present invention is a polyethylene film 1
The reason for this is that the leaked milk absorbed and retained by the absorbent material 2 does not leak to the clothing side. outer layer 1
The reason why the outside is made of rayon paper 1b is that when the polyethylene film is exposed, it is inferior not only in appearance but also in feel. By laminating rayon paper, which has excellent appearance and feel, this problem can be overcome. It has been improved. To laminate the two, it is sufficient to overlap the polyethylene film 1a and the rayon paper 1b and heat and press them together. Of course, there are many synthetic resin membrane bodies as well.
Although leakproof, a polyethylene membrane is used because it is easy and inexpensive to laminate with rayon paper. Note that since rayon paper has water absorption properties, it has the advantage of being able to absorb and retain even a small amount of milk leakage.

The absorbent material 2 used in the present invention is not particularly different from those conventionally used in products of this type. The most typical material is absorbent paper, but it is recommended to interpose a known synthetic or semi-synthetic polymeric liquid-absorbing agent (for example, described in Japanese Patent Publication No. 49-43395) between the sheets. . In addition, absorbent materials such as absorbent cotton and flat pulp may be used alone or in combination.

The inside of the inner layer 3 according to the present invention is made of water-permeable nonwoven fabric 3
It is a. Water permeability means that recently, water-impermeable nonwoven fabrics made from ultra-fine fibers (0.03 denyl) of polypropylene or polyamide using the Exxon method have been commercially available (for example, Tapyrus, manufactured by Tonen Petrochemical Co., Ltd.). This means that this type of nonwoven fabric is to be excluded.

The reason for using a water-permeable non-woven fabric inside the inner layer is that the intertwined fiber structure of the non-woven fabric is breathable and comfortable to the touch, and it is also extremely strong and does not tear easily even if there is some milk leakage. It's for a reason. The reason why the outer side of the inner layer is made of polyethylene film 3b is to prevent milk leakage absorbed and retained by the absorbent material 2 from leaking out to the skin side through the nonwoven fabric 3b.

The laminate of polyethylene membrane and non-woven membrane is
As in the case of the outer layer, this can be done by overlapping the two and heat-sealing them. If the two were completely laminated, the air permeability of the nonwoven fabric would be adversely affected, so in the present invention, the polyethylene membrane is used with a large number of ventilation holes. Therefore, in the most preferred embodiment of the present invention, the nonwoven fabric 3a and the polyethylene film 3b are superimposed, and a heating body, such as a heating roll, having a large number of protrusions corresponding to the size of the ventilation holes is pressed onto the nonwoven fabric 3a and the polyethylene film 3b. do. Of course, the protrusion temperature is set to be at or slightly higher than the melting point of polyethylene. Then, the polyethylene film 3b has as many melt holes as the number of protrusions, and the ventilation holes 4 as shown in FIG.
At the same time, the melted polyethylene acts as a glue 5, thereby completing the lamination of the polyethylene film 3b and the nonwoven fabric.

The advantage of the vent hole 4 being a melted hole is that it is difficult to tear, unlike a case where the vent hole is simply mechanically cut, drilled, or punctured. This is because the circumference of the melt hole is homogenized by melting. On the other hand, in the case of a cut or the like, minute scratches occur on the circumference, and these are likely to cause the cut. The size of the ventilation holes 4 is usually about 0.5 to 5 mm in diameter, and the distance between the holes is 0.5 to 5 mm.
Although the degree is considered appropriate, there is no particular limitation. In addition, the ventilation hole 4 does not need to be formed on the entire surface of the inner layer, and the ventilation hole 4 does not need to be formed on the entire surface of the inner layer.
They are scattered only in the upper half of the polyethylene film 3b, and are formed by thermal melting on the polyethylene film 3b.

The reason why the plurality of ventilation holes 4 are scattered in the upper half area of the inner layer 3 above the nipple insertion holes 7 is that minute water droplets of gases such as moisture, steam, and sweat emitted from the skin rise and This is because it passes through the nonwoven fabric 3a, passes through the ventilation holes 4, and is absorbed by the absorbent material 2, so it has excellent breathability and does not cause the discomfort of stuffy breasts.

Furthermore, since the liquid such as milk sucked by the absorbent material 2 falls due to gravity, the absorbed liquid
In the lower part of the absorbent material 2, a larger amount is absorbed and stored than in the upper part of the absorbent material 2. In the present invention, as shown in FIG. 3, ventilation holes 4 are not provided in the lower half of the inner layer 3, so that the
b prevents liquids such as milk from flowing back toward the skin.

If the ventilation holes 4 were also provided in the lower half of the polyethylene film 3b of the inner layer 3, a large amount of air would accumulate in the lower part of the absorbent material 2 due to the compression of the absorbent material 2 when the infant presses the breast. The absorbed liquid, such as milk, is pushed out of the absorbent material 2, some of which is transferred to the upper half area of the absorbent material 2, and some of which is transferred to the vent hole 4.
There is a possibility that it may seep through the nonwoven fabric 3a and return to the skin side. In the present invention, since the ventilation holes 4 are provided in the upper half of the inner layer 3, such problems do not occur, and there is no discomfort caused by liquids such as milk returning to the skin side, and there are no hygiene problems. can also be effectively prevented.

Furthermore, the plurality of ventilation holes 4 are arranged in the nonwoven fabric 3.
Since it is not provided on the polyethylene film 3b and is formed only on the polyethylene film 3b, the present invention has the advantage that it does not feel uncomfortable when worn and is comfortable to the touch.

In order to manufacture the pad of the present invention, an inner layer 3 cut out in a circular shape, an absorbent material 2, and an outer layer 1 are laminated on a bowl-shaped core (not shown), and the outer periphery of the inner layer 3 is laminated with a seal 6.
do it.

Since the present device is constructed as described above, it is comfortable to wear, there is little discomfort caused by the breasts becoming engorged, and there is little leakage of absorbed milk.

Of course, it is easy and inexpensive to manufacture.
