Abstract

A device for transporting objects such as a graft is configured to efficiently establish a liquid-tight state with a simple operation. The device is to be used in a state of being detachably attached to a container for storing a graft, the device including: a lid member for sealing the container; and an annular member for forming a first space by being interposed between the lid member and the container, wherein a second space is formed between the lid member and an inside surface of the container.

First claim

What is claimed is:

1. A graft-transporting device comprising:
a container having an interior in which is positioned liquid and a graft, the container includes a bottom surface and a side wall extending upwardly away from the bottom surface, the side wall possessing an inner surface so that the bottom surface and the inner surface of the side wall surround the interior of the container, the container also including an open end, the side wall of the container including an upper edge;
an annular member surrounding a centrally located first space, the annular member having oppositely facing first and second surfaces, the first surface of the annular member facing towards the bottom surface of the container and the second surface facing away from the bottom surface of the container, the annular member being positioned in the container so that the graft is located in the centrally located first space;
a lid positioned at and closing the open end of the container to seal the interior of the container;
a protective member overlying the first space of the annular member and positioned between the second surface of the annular member and the lid to protect the first space, the protective member being made of a fluid impermeable material so that gas and liquid do not pass through the protective member;
a second space in the interior of the container between the lid and the inner side wall surface of the container; and
a seal positioned between and in contact with the upper edge of the side wall of the container and an inner surface of the lid.

2. The graft-transporting device according to claim 1 , wherein the lid comprises a top part, a protruding part extending downward from the top part toward the bottom surface of the container, and a skirt wall extending downward from the top part toward the bottom surface of the container, the skirt wall being positioned radially outwardly of the protruding part so that the second space exists between the skirt wall and the protruding part.

3. The graft-transporting device according to claim 2 , wherein the skirt wall of the lid possesses an inner surface and the side wall of the container possesses an outer surface, the skirt wall of the lid being positioned outside the side wall of the container so that the inner surface of the skirt wall of the lid faces the outer surface of the side wall of the container.

4. The graft-transporting device according to claim 2 , wherein the protruding part of the lid possesses an outer surface and is positioned in the interior of the container so that the second space is defined between the outer surface of the protruding part and the inner surface of the side wall of the container.

5. The graft-transporting device according to claim 1 , wherein the protective member is flexible.

6. The graft-transporting device according to claim 1 , wherein the protective member and/or the lid is water repellent.

7. The graft-transporting device according to claim 1 , wherein the lid comprises a top part, a protruding part extending downward from the top part toward the bottom surface of the container and terminating in a bottom surface, and a skirt wall extending downward from the top part toward the bottom surface of the container, the skirt wall being positioned radially outwardly of the protruding part so that the second space exists between the skirt wall and the protruding part, the bottom surface of the protruding wall being in contact with the protective member.

8. The graft-transporting device according to claim 1 , wherein the graft is a sheet-shaped cell culture.

9. The graft-transporting device according to claim 8 , wherein the sheet-shaped cell culture is a laminate.

10. A device to be detachably attached to a container that possesses an inside surface upstanding from a bottom surface and an open end opposite the bottom surface, and that contains a graft, the device comprising:
an annular member having a through hole passing through and opening to opposite surfaces of the annular member so that the through hole defines a first space surrounded by the annular member, the opposite surfaces of the annular member being first and second surfaces, the annular member having an outer periphery, the annular member being positionable in the container so that the first surface of the annular member faces the bottom surface of the container and the graft is located in the first space;
a lid positionable at the open end of the container to seal the container, the lid being positionable at the open end of the container after the annular member is positioned in the container so that the annular member is interposed between the lid and the bottom surface of the container;
the lid being configured so that when the lid is positioned at the open end of the container to seal the container, a second space exists between the lid and the inside surface of the container;
a protective member configured to be positioned on the second surface of the annular member so that the protective member is between the annular member and the lid to protect the first space, the protective member having an outer periphery, the protective member being configured so that when the protective member is positioned on the second surface of the annular member, the protective member completely covers the through hole in the annular member to protect the first space while the outer periphery of the protective member is located other than radially outwardly of the outer periphery of the annular member, the protective member being made of a fluid impermeable material so that gas and liquid do not pass through the protective member; and;
a sealing member configured to be interposed between an upper end of an upstanding wall of the container and an inner surface of the lid.

11. The device according to claim 10 , wherein the protective member is flexible.

12. The device according to claim 10 , wherein the protective member and/or the lid is water repellent.

13. The device according to claim 10 , wherein the lid comprises a top part, a protruding part extending downward from the top part so that the protruding part extends toward the bottom surface of the container when the lid is positioned at the open end of the container to seal the container, and a skirt wall extending downward from the top part, the skirt wall being positioned radially outwardly of the protruding part so that the second space exists between the skirt wall and the protruding part.

14. A gripping tool comprising:
a cover member; and
a base member,
the gripping tool being configured to press and grip the device according to claim 10 from above and below.

15. A method comprising;
positioning an annular member in an interior of a container by introducing the annular member through an open end of the container, the container including a bottom surface positioned opposite the open end and an inside surface extending away for the bottom surface so that the interior of the container is surrounded by the bottom surface and the inside surface, the annular member being configured so that the annular member surrounds a first space and the annular member being located in the container so that a graft and liquid are in the first space, the annular member having oppositely facing first and second surfaces, the first surface of the annular member facing towards the bottom surface of the container and the second surface of the annular member facing away from the bottom surface of the container;
positioning a protective member on the second surface of the annular member so that the protective member overlies the first space and covers the through hole
