Abstract

Provided is a solid antimicrobial agent suitable for portable use, which can continuously release a stable amount of chlorine dioxide even under vibration or shock. An antimicrobial pouch includes: an antimicrobial agent supporting an antimicrobial substance in a porous inorganic solid carrier; a first pouch body receiving the antimicrobial agent; and a second pouch body receiving the first pouch body, wherein the first pouch body includes fine holes on an entire surface, the fine holes having a diameter smaller than a particle size of the inorganic solid carrier, and the second pouch body includes release holes at an edge portion, the release holes through which the antimicrobial substance is released to atmosphere of the second pouch body.

Claims (29)

1. An antimicrobial pouch for portable use comprising:

an antimicrobial agent supporting an antimicrobial substance in a porous inorganic solid carrier;

a first pouch body receiving the antimicrobial agent; and

a second pouch body receiving the first pouch body,

wherein the first pouch body has a flat shape, and comprises fine holes on an entire surface, the fine holes having a diameter smaller than a particle size of the inorganic solid carrier,

the second pouch body comprises two sheets of light blocking films bonded to each other at a bonding portion formed along a whole periphery of the light blocking films, and has a flat shape, and has regions where both sides of the first pouch body contact an inside of the second pouch body, and a region where a space is formed between the first pouch body and the second pouch body,

the second pouch body further comprises a hanging hole provided on the bonding portion, and a release hole through which the antimicrobial substance is released to atmosphere when the antimicrobial pouch is carried, and

the release hole is provided at an edge portion of the second pouch body adjacent to the hanging hole at the region of the second pouch body where the space is formed.

2. The antimicrobial pouch according to claim 1 , wherein the second pouch body is manufactured by pressure-bonding the periphery of the light blocking films.

3. The antimicrobial pouch according to claim 1 , wherein the second pouch body has a flat polygonal shape.

4. The antimicrobial pouch according to claim 1 , wherein a volume ratio of the first pouch body to the second pouch body is 1:3 to 1:1.2.

5. The antimicrobial pouch according to claim 1 , wherein the inorganic solid carrier is a particle having an average particle size of 0.01 to 1 mm, and a filling rate of the inorganic solid carrier in the first pouch body is 30 to 80%.

6. The antimicrobial pouch according to claim 1 , wherein the release hole is blocked by a peelable seal.

7. The antimicrobial pouch according to claim 1 , wherein the antimicrobial substance is chlorine dioxide, and the inorganic solid carrier is at least one selected from sepiolite, zeolite, silica, alumina, and silica alumina.

8. An antimicrobial pouch for portable use comprising:

an antimicrobial agent supporting an antimicrobial substance in a porous inorganic solid carrier;

a first pouch body receiving the antimicrobial agent; and

a second pouch body receiving the first pouch body,

wherein the first pouch body has a flat shape, and comprises fine holes on an entire surface, the fine holes having a diameter smaller than a particle size of the inorganic solid carrier,

the second pouch body comprises two sheets of light blocking films bonded to each other at a bonding portion formed along a whole periphery of the light blocking films, and has a flat shape, and has regions where both sides of the first pouch body contact an inside of the second pouch body,

the second pouch body further comprises a hanging hole provided on the bonding portion, and a row of release holes through which the antimicrobial substance is released to atmosphere when the antimicrobial pouch is carried, and

the row of release holes are provided at an edge portion of the second pouch body adjacent to the hanging hole of the second pouch body.

9. The antimicrobial pouch according to claim 8 , wherein the second pouch body is manufactured by pressure-bonding a periphery of the light blocking films.

10. The antimicrobial pouch according to claim 8 , wherein the second pouch body has a flat polygonal shape.

11. The antimicrobial pouch according to claim 8 , wherein a volume ratio of the first pouch body to the second pouch body is 1:3 to 1:1.2.

12. The antimicrobial pouch according to claim 8 , wherein the inorganic solid carrier is a particle having an average particle size of 0.01 to 1 mm, and a filling rate of the inorganic solid carrier in the first pouch body is 30 to 80%.

13. The antimicrobial pouch according to claim 8 , wherein the release holes are blocked by a peelable seal.

14. The antimicrobial pouch according to claim 8 , wherein the antimicrobial substance is chlorine dioxide, and the inorganic solid carrier is at least one selected from sepiolite, zeolite, silica, alumina, and silica alumina.

15. The antimicrobial pouch according to claim 8 , wherein the two sheets of light blocking films comprise first and second light blocking films, the row of release holes are provided on an upper part of the first film along the bonding portion, and a second row of release holes are provided on a lower part of the second film along the bonding portion.
