Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

Feeding pad 100 according to an embodiment of the present invention, as shown in Figure 1 and 2, the outer cover 10 in contact with the inside of the bra (not shown); An inner cover provided on the outer cover and in contact with the breast; And a breast milk absorbing stand 20 provided between the outer cover and the inner cover.

Here, the outer cover 10, like the breathable waterproof non-woven fabric, it is preferable that the waterproof coating film is provided on the outer surface facing the bra. The waterproof coating film may be provided with an attachment means (for example, an adhesive) to be attached to the inside of the bra, when the adhesive is partially applied, as shown in Figure 2, the adhesive cover sticker 22 on the adhesive coated portion May be further attached.

The inner cover 30 is the same size and shape as the outer cover 10, as shown in Figure 2, is provided to contact with the teat to first absorb the mother milk to transfer to the breast milk absorbing table (20). To this end, the material of the inner cover 30 may be any one as long as it can absorb and transfer breast milk, but it is preferable that the non-woven fabric can provide a soft feeling when touching the breast 1 as well as absorbing liquid. .

The breast milk absorbing stand 20 is provided on the outer cover 10 smaller than the outer cover 10 and the inner cover 30, as shown in FIG. 2, into the edges of the outer cover 10 and the inner cover 30. It is preferable to encapsulate in a manner such as pressurization. In addition, it is preferable to have a predetermined through hole 21 in a portion corresponding to the teat, such as the middle portion of the breast milk absorption table 20.

5 and 6, as described above, by providing a through-hole 21 in the breast milk absorber 20, to reduce the pressure on the teat as much as the thickness of the breast milk absorber 20 when worn on the breast (1). In addition, even when the breast milk absorbing table 20 expands due to absorption of breast milk, the nipple is naturally wrapped in the through hole 21, thereby eliminating the feeling of pressure on the nipple.

Therefore, the breast milk absorber 20 may be made of a material (eg, pulverized pulp) which does not have a volume change after absorption of breast milk, and may be made of a material containing an swelling agent that is expanded upon absorption but has absorbent and / or water retention. .

Specifically, as shown in FIG. 3, the breastmilk absorbing table 20 is a donut-shaped absorbing expansion made of fluffy grinding pulp at a predetermined thickness between the outer cover 10 and the inner cover 30, around the through hole 21. Layer 22; A lower absorbent film 24 covering the through hole 21 between the absorbent expansion layer 22 and the outer cover 10; And an upper absorbent film 26 covering the through hole 21 between the absorbent expansion layer 22 and the inner cover 30.
