Abstract

The present invention provides a microneedle patch container for effectively and hygienically securing a microneedle patch from manufacture to use. The container has a bottom surface recessed from the peripheral portion towards the center, a side surface connected to the bottom surface and the peripheral portion, and a bottom-surface protruding portion protruding from the bottom surface. The flexible release-type sheet portion of the microneedle patch is secured to the protruding portion on the bottom surface. A lid can also be used which has a recessed portion pressing against the microneedle patch secured to the bottom-surface protruding portion of the container in the position corresponding to the bottom-surface protruding portion. This is preferably housed inside a pouch molded from sterilized paper or sterilized film in order to keep the microneedle patch in an aseptic state.

Claims

1. A microneedle patch container having a flexible microneedle patch therein, said container comprising:

one or plural bottom surfaces recessed from a peripheral portion;

a side surface continuously connecting the one or plural bottom surfaces with the peripheral portion; and

a bottom-surface protruding portion projecting from each of the one or plural bottom surfaces,

wherein the flexible microneedle patch comprises an adhesive sheet having an adhesive surface, a microneedle array disposed on the adhesive surface, and a release sheet portion stuck on the adhesive surface outside a region wherein the microneedle array is disposed, and

wherein the release sheet portion of the flexible microneedle patch is held with the bottom-surface protruding portion of each of the one or plural bottom surfaces so that a microneedle of the microneedle array is elongated from the adhesive surface towards the one or plural bottom surfaces of the microneedle patch container.

2. The microneedle patch container according to claim 1, further comprising a lid, wherein

the lid has recessed portions which respectively press the flexible microneedle patch on each bottom-surface protruding portion in a position corresponding to a part, but not all, of the bottom-surface protruding portion.

3. The microneedle patch container according to claim 2, characterized in that an area of each bottom-surface protruding portion of the container is larger than an area of the respective recessed portion of the lid.

4. The microneedle patch container according to claim 2, characterized by comprising a cut and a protrusion in corresponding positions of the microneedle patch container and the lid.

5. The microneedle patch container according to claim 1, characterized in that each bottom-surface protruding portion has a rectangular shape.

6. The microneedle patch container according to claim 1, characterized in that each bottom-surface protruding portion is arranged so that a plurality of convex parts support four sides of the release sheet portion of the flexible microneedle patch.

7. The microneedle patch container according to claim 1, wherein the flexible microneedle patch holds two or more microneedle arrays.

8. A plurality of microneedle patch containers, comprising:

first and second microneedle patch containers, each of said first and second microneedle patch containers corn rising the microneedle patch container having the flexible microneedle patch therein according to claim 1,

wherein the first and second microneedle patch containers are stacked such that the release sheet portion of the flexible microneedle patch in the first microneedle patch container is partially pressed by a bottom part of the second microneedle patch container.

9. The microneedle patch container according to claim 1, characterized in that a swollen part for accommodating fingers of a user and facilitating easy pick up of the flexible microneedle patch is provided in the bottom surface.

10. The microneedle patch container according to claim 1, characterized in that the surfaces are anti-static treated.
