Abstract

A flat IC tag contains memory means capable of data storage and transmission means capable of data transmission. The IC tag has on a surface thereof an unvulcanized rubber having identical properties to the unvulcanized rubber used for an article to which the IC tag is mounted. The opposite surface of the IC tag is mounted to the article before vulcanization. The article is vulcanized in this state to mount the IC tag to the article. Hence, the IC tag is not damaged if attached to tires and other articles in harsh operating environment.

Claims

1. A method of securing a wireless IC tag, comprising the steps of:

directly covering an entire first surface of a wireless IC tag with a rubber member consisting of an unvulcanized rubber having identical properties to an unvulcanized rubber constituting an article to which the wireless IC tag will be secured, the wireless IC tag including memory means for storing data and wireless transmission means for wirelessly transmitting data;

mounting a second surface of the wireless IC tag which is opposite the first surface to the article before vulcanization; and

vulcanizing the article and the wireless IC tag to secure the wireless IC tag to the article,

wherein the rubber member covering the wireless IC tag has such a size that the rubber member cannot be secured directly to the article around the wireless IC tag before the vulcanization, but can be secured directly to the article around the wireless IC tag after the rubber member undergoes plastic deformation and thus expands in the vulcanization.

2. The method of claim 1, wherein the wireless IC tag is secured to the article at a place other than a joint of the unvulcanized rubber constituting the article.

3. The method of either one of claims 1 and 2, wherein the unvulcanized rubber covering the entire first surface of the wireless IC tag is softer than the unvulcanized rubber constituting the article to which the wireless IC tag is secured.

12. The method of claim 1, wherein the rubber member is secured directly to the article around the wireless IC by fusing along a periphery of the wireless IC tag.

4. A wireless IC tag carrying article, in which:

an entire first surface of a wireless IC tag is directly covered with a rubber member consisting of an unvulcanized rubber having identical properties to an unvulcanized rubber constituting an article to which the wireless IC tag will be secured, the wireless IC tag including memory means for storing data and wireless transmission means for wirelessly transmitting data;

a second surface of the wireless IC tag which is opposite the first surface is mounted to the article before vulcanization; and

the article and the wireless IC tag are vulcanized to secure the wireless IC tag to the article,

wherein the rubber member covering the wireless IC tag has such a size that the rubber cannot be secured directly to the article around the wireless IC tag before the vulcanization, but can be secured directly to the article around the wireless IC tag after the rubber member undergoes plastic deformation and thus expands in the vulcanization.

5. The wireless IC tag carrying article of claim 4, wherein the wireless IC tag is secured to the article at a place other than a joint of the unvulcanized rubber constituting the article.

6. The wireless IC tag carrying article of claim 4, wherein the unvulcanized rubber covering the entire first surface of the wireless IC tag is softer than the unvulcanized rubber constituting the article to which the wireless IC tag is secured.

11. The wireless IC tag carrying article of claim 5, wherein the unvulcanized rubber covering the entire first surface of the wireless IC tag is softer than the unvulcanized rubber constituting the tire to which the wireless IC tag is secured.

13. The wireless IC tag carrying article of claim 4, wherein the rubber member is secured directly to the article around the wireless IC by fusing along a periphery of the wireless IC tag.

7. A vehicle, comprising a rubber tire, in which:

an entire first surface of a wireless IC tag is directly covered with a rubber member consisting of an unvulcanized rubber having identical properties to an unvulcanized rubber constituting the tire to which the wireless IC tag will be secured, the wireless IC tag including memory means for storing data and wireless transmission means for wirelessly transmitting data;

a second surface of the wireless IC tag which is opposite the first surface is mounted to the tire before vulcanization; and

the tire and the wireless IC tag are vulcanized to secure the wireless IC tag to the tire,

wherein the rubber member covering the wireless IC tag has such a size that the rubber member cannot be secured directly to the tire around the wireless IC tag before the vulcanization, but can be secured directly to the tire around the wireless IC tag after the rubber undergoes plastic deformation and thus expands in the vulcanization.

8. The vehicle of claim 7, wherein the wireless IC tag is secured to the tire at a place other than a joint of the unvulcanized rubber constituting the tire.

9. The vehicle of claim 7, wherein the unvulcanized rubber covering the entire first surface of the wireless IC tag is softer than the unvulcanized rubber constituting the tire to which the wireless IC tag is secured.

10. The vehicle of claim 8, wherein the unvulcanized rubber covering the entire first surface of the wireless IC tag is softer than the unvulcanized rubber constituting the tire to which the wireless IC tag is secured.

14. The vehicle of claim 7, wherein the rubber member is secured directly to the tire around the wireless IC by fusing along a periphery of the wireless IC tag.
