Fragile object preserving device provided with sealing mechanism

A device, the device comprising:

• a container, the container having a cylindrical shape including a bottom, a lower portion, an upper portion having an opening, and an annular stepped portion extending from the lower portion of the container to the upper portion of the container, the annular stepped portion including an annular surface having a width obtained by a difference between an inside diameter of the upper portion of the container and an inside diameter of the lower portion of the container;
• a packing ring configured to be received on the annular surface of the stepped portion of the container, the packing ring having a diameter smaller than the inside diameter of the upper portion of the container and larger than the inside diameter of the lower portion of the container;
• a lid configured to seal the opening of the upper portion of the container;
• a seal, the seal representing a portion being interposed between the lid and the stepped portion, the seal extending from the lid and having an outside diameter larger than an inside diameter of the lower portion of the container, and wherein the outside diameter of the seal is smaller than the inside diameter of the upper portion of the container, such that, upon inserting the seal into the container, a space is created between an outer periphery of the seal, an outer periphery of the packing ring, and an inner periphery of the upper portion of the container, and wherein the seal is configured to seal an opening of the lower portion of the container by a bottom surface of the seal coming into contact with the packing ring on the annular surface of the stepped portion;
• wherein the inside diameter of the upper portion of the container is larger than the inside diameter of the lower portion of the container;
• a space in the lower portion represents a housing space surrounded by the lower portion of the container, a space in the upper portion represents a space surrounded by the upper portion of the container, an opening of the space in the lower portion represents a boundary edge between the space in the lower portion and the stepped portion, and an opening of the space in the upper portion represents an end of the space in the upper portion;
• a mesh plate, the mesh plate having a diameter larger than the inside diameter of the lower portion of the container and smaller than the diameter of the packing ring, the mesh plate configured to be placed on the annular surface of the stepped portion, and wherein the mesh plate has a mesh network configured to allow a liquid to pass through the mesh network;
• and
• wherein when the container is sealed with the lid, a space configured to preserve a fragile object is formed between the mesh plate and the seal extending from the lid.

A method for preserving a fragile object, the method comprising:

• pouring a liquid in a lower portion of a container until the liquid rises above an elastic packing ring on an annular surface of a stepped portion of the container, the stepped portion being between a lower portion of the container and an upper portion of the container, the stepped portion including the annular surface having a width obtained by a difference between an inside diameter of the upper portion of the container and an inside diameter of the lower portion of the container, the inside diameter of the upper portion of the container being larger than the inside diameter of the lower portion of the container, and the packing ring having a diameter smaller than the inside diameter of the upper portion of the container and larger than the inside diameter of the lower portion of the container;
• arranging a mesh plate on the annular surface of the stepped portion of the container and inside of the packing ring, the mesh plate having a diameter larger than the inside diameter of the lower portion of the container and smaller than the diameter of the packing ring;
• placing the fragile object into the liquid in the container;
• interposing a seal between a lid configured to seal an opening of the upper portion of the container and the packing ring on the stepped portion, the seal representing a portion being interposed between the lid and the stepped portion, the seal extending from the lid and having an outside diameter larger than the inside diameter of the lower portion of the container, the outside diameter of the seal being smaller than the inside diameter of the upper portion of the container;
• covering the container with the lid and the seal to raise a level of the liquid in the lower portion of the container and pushing the liquid from the container into a space between an outer periphery of the seal, an outer periphery of the packing ring, and an inner periphery of the container until a bottom surface of the seal and the packing ring on the annular surface of the stepped portion come into contact with each other at a same time the lid is attached to the container;
• and
• preserving the fragile object between the mesh plate and the seal extending from the lid.
