Claim:
A chip container comprising: a first rim that delineates a first opening through which an unused microneedle chip held in the container is removable, the first opening being opened in a direction parallel to an axis of the container; a first holder configured to removably hold the unused microneedle chip in the container, the first holder being formed in the first opening so as to allow access through the first opening to the unused microneedle chip held in the container and allow removal of the unused microneedle chip from the container, wherein the first rim is formed with one of a projection and a recess, which is in agreement with the other thereof formed on the microneedle chip; a second rim that delineates a second opening through which a used microneedle chip is only insertable for storage in the container and not removal from the container, the second opening being opened in a direction parallel to the axis of the container and opposite to the direction of the first opening; and a second holder configured to unremovably hold the used microneedle chip in the container, the second holder being formed in the second opening so as to receive the microneedle chip through the second opening and prohibit removal of the microneedle chip from the container, wherein the second holder comprises at least one beam which is formed with a complementary key structure engageable with a key structure of the microneedle chip, the complementary key structure of the at least one beam and the key structure of the microneedle chip being a key hole and a key projection engageable with each other, and the at least one beam is flexed to lead the key structure of the microneedle chip to engagement with the complementary key structure of the at least one beam and flexed back upon engagement between the complementary key structure and the key structure to secure the engagement.
