Abstract

PURPOSE:To provide a milk pad having an effective antibacterial function. CONSTITUTION:This milk pad has a silver-containing antibacterial agent 5 dispersed in absorbing materials 2 and 3 comprising a highly absorbing polymer 3. Hence, silver ions are eluted from the silver-containing antibacterial agent gradually when the agent is brought into contact with the milk. The proliferation or saprophytes is checked by antibacterial action of the silver ions thereby enabling the elimination of discomfort and rash or the like of a nipple.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a breast milk pad having an antibacterial function.

[0002]

2. Description of the Related Art Breastfeeding pads used by women during breastfeeding are
It is common to store absorbent paper, super absorbent polymer, and other absorbent materials inside a non-woven surface material that softens the feeling of contact with the skin, and cover the outside with waterproof paper.

Such a breast milk pad may be worn for a maximum of overnight, and various measures have been taken regarding the water absorbing and waterproofing functions during that time.

However, it is unavoidable that the absorbed milk is decomposed by various bacteria with the passage of time to generate a putrid odor, which causes discomfort or a rash on the nipple.

[0005]

By the way, Japanese Unexamined Patent Publication No.
Japanese Patent No. 136649 discloses an antibacterial cloth containing antibacterial metal atoms for the prevention of mastitis in milking cows, but it is premised that the cloth is applied to cows and has an absorbent material called a breast milk pad. The optimal composition for the material has not been proposed yet.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mother's milk pad having antibacterial and deodorant functions, which can solve the above-mentioned conventional problems and effectively prevent discomfort and nipple rash. To do.

[0007]

In order to solve the above-mentioned problems, the present invention is characterized in that a silver-containing antibacterial agent is dispersed on the inner surface or the outer surface of the absorbent material.

[0008]

The silver-containing antibacterial material used in the present invention is capable of gradually eluting silver ions in the antibacterial agent when brought into contact with breast milk, and the antibacterial effect of silver ions suppresses the growth of various bacteria. It is possible to eliminate discomfort and nipple irritation.

[0009] The silver-containing antibacterial agent is made by supporting silver ions, which are safe for the human body, on various supporting materials. Depending on the supporting material, zeolite type (for example, Zeomic manufactured by Shinagawa Fuel), silica gel type (Amenitop manufactured by Matsushita Electric Industrial) , Soluble glass type (Ion Pure made by Ishizuka glass), and calcium phosphate type, zirconium phosphate type, titania type, etc. are commercially available although the product names are not clear.

When the above antibacterial agent is kneaded into the superabsorbent polymer, the antibacterial agent containing silver oxide, for example, in an amount of 1% by weight is used in a particle size of 50 μm or less, and the amount of the antibacterial agent is 0.1 to 0.1% per one milk pad.
It is preferable to use it at a rate of about 5 g.

When the antibacterial agent is mixed with the absorbent polymer, it is preferable to use the antibacterial agent with a particle size of 50 to 1000 μm and a ratio of about 0.1 to 5 g per one breast milk pad.

When a large particle size antibacterial agent is used, it is preferable to use a spherical antibacterial agent for safety reasons.

Further, when the antibacterial agent is adhered to the inner surface of the absorbent paper, the antibacterial agent containing 0.5 to 1% by weight of silver oxide should have a particle size of 50 μm or less and a urethane type adhesive agent should be used. It is preferable to use at a rate of about 1 to 5 g per sheet.

It is also possible to disperse it in a concentrated manner particularly in the part that comes into contact with the milk.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 shows a cross section of a breast milk pad according to an embodiment of the present invention, wherein 1 is a nonwoven fabric, 2 is an absorbent paper, 3 is a super absorbent polymer, and 4 is a waterproof paper. In this embodiment, the silver-containing antibacterial agent 5 is added to the water-absorbent polymer 3 portion.
Was mixed at a rate of 0.5 g. The absorbent paper 2 and the super absorbent polymer 3 constitute an absorbent material.

The antibacterial agent used is ION PURE made by Ishizuka Glass Co., Ltd. containing 1% by weight of silver oxide, and is 50 to 200.
What was pulverized to μm was used.

With respect to the deodorizing function of the breast milk pad of such an example, the presence of odor was checked by sensory test of 3 people after putting the sample and breast milk in a standard agar medium and culturing at 35 ± 1 ° C. and 30% humidity for 15 hours. It was inspected by the method of inspecting.

As a result, 2 out of 3 persons judged that the breast milk pads of the examples had remarkably less rotten odor compared to the conventional breast milk pads, and 1 person judged that they were slightly less.

(Example 2) Next, 1% by weight in terms of silver oxide
50 made by Matsushita Electric Industrial Co., Ltd.
An antibacterial agent was obtained by pulverizing to a size of less than μm. A urethane emulsion type adhesive was applied to the inner surface of the absorbent paper 2 of the above-mentioned mother's milk pad, and this antibacterial agent was sprayed for adhesion. The amount of glass was 1 g.

The breast milk pad thus obtained has 50
cc breast milk was poured and allowed to stand for 6 hours and 12 hours at 35 ± 1 ° C. and 30% humidity for odor inspection. As a result, after 6 hours, the milk pad of this example had a slightly less rotten odor than the conventional milk pad, and after 12 hours, the milk pad of the example had a significantly rotten odor as compared to the conventional milk pad. It was judged to be few.

The absorbent material of the present invention is not limited to the absorbent paper and superabsorbent polymer used in the above-mentioned embodiments, but may be other absorbent materials.

Needless to say, the silver-containing antibacterial agent of the present invention is not limited to the materials of the above-mentioned examples.

[0024]

As is apparent from the above description,
In the breast milk pad of the present invention, the silver-containing antibacterial agent is dispersed on the inner surface or the outer surface of the absorbent material, so that the eluted silver ions can sterilize various bacteria and suppress the putrefactive odor.

For this reason, the discomfort and the risk of nipple rash can be almost completely eliminated.
