Packaging member and packaging method

1. A packaging member comprising:

a cushioning member configured to hold a holding part of a to-be-packaged member different from a predetermined part of the to-be-packaged member without coming into contact with the predetermined part of the to-be-packaged member; and

a wall member configured to stand in a standing direction from a bottom of the cushioning member, wherein

the cushioning member is configured to cushion a shock transmitting to the to-be-packaged member,

the packaging member packages the to-be-packaged member via the cushioning member,

the cushioning member is a hollow member and includes four flat members collectively bounding a hollow space,

the holding part of the to-be-packaged member is held by the cushioning member in such a manner that a space is provided between the holding part of the to-be-packaged member and a wall of the packaging member,

the cushioning member has a rectangular shape containing the holding part of the to-be-packaged member by the four flat members, and the adjacent ones of the four flat members intersect to form ridge lines in contact with four wall faces of top, bottom and both side faces of the packaging member, respectively, and

a flat member amongst the four flat members of the cushioning member includes a to-be-engaged part that engages with the wall member to secure the wall member to the flat member and thereby secure the bottom of the cushioning member,

wherein the wall member is configured to stand from the bottom of the cushioning member at one end of the wall member in the standing direction, and the other end of the wall member which is another end of the wall member in the standing direction of the wall member is engaged with the to-be-engaged part, and

wherein one of the wall member and the to-be-engaged part of the flat member is an insert part and the other of the wall member and the to-be-engaged part of the flat member includes a cut portion, and the insert part is inserted into the cut portion to secure the wall member to the flat member and thereby secure the bottom of the cushioning member.

2. The packaging member as claimed in claim 1 , wherein

a space is provided between a most projecting part of the predetermined part of the to-be-packaged member and a wall surface of the packaging member for preventing the most projecting part from coming into contact with the wall surface.

3. The packaging member as claimed in claim 1 , wherein

the ridge lines on which the adjacent ones of the four flat members intersect, respectively, are positioned approximately at the centers of the four wall faces of top, bottom and both side faces of the packaging member, respectively.

4. The packaging member as claimed in claim 1 , wherein the to-be-packaged member comprises:

a receiving container including a container body as the holding part having a containing part that contains contents and a content outlet;

a cap member as the predetermined part that is fitted to the container body to cover the content outlet; and

a sealing member inserted between the container body and the cap member, wherein

the cushioning member is used to hold the container body in such a manner that the cap member and the cushioning member do not come into contact with one another.

5. The packaging member as claimed in claim 1 , wherein the bottom of the cushioning member is configured to contact at least a portion of the bottom wall surface of the packaging member.

6. A packaging method of containing and packaging a to-be-packaged member in the inside of a packaging member via a cushioning member, the packaging method comprising:

providing the cushioning member to hold a holding part of the to-be-packaged member; and

containing the to-be-packaged member in the inside of the packaging member in a state where a predetermined part of the to-be-packaged member different from the holding part of the to-be-packaged member is suspended in the space inside of the packaging member, wherein

the packaging member comprises the cushioning member and a wall member configured to stand in a standing direction from a bottom of the cushioning member,

the cushioning member is a hollow member and includes four flat members collectively hounding a hollow space,

the holding part of the to-be-packaged member is held by the cushioning member in such a manner that a space is provided between the holding part of the to-be-packaged member and a wall of the packaging member,

the cushioning member has a rectangular shape containing the holding part of the to-be-packaged member by the four flat members, and the adjacent ones of the four flat members intersect to form ridge lines in contact with four wall faces of top, bottom and both side faces of the packaging member, respectively, and

a flat member amongst the four flat members of the cushioning member includes a to-be-engaged part that engages with the wall member to secure the wall member to the flat member and thereby secure the bottom of the cushioning member,

wherein the wall member is configured to stand from the bottom of the cushioning member at one end of the wall member in the standing direction, and the other end of the wall member which is another end of the wall member in the standing direction of the wall member is engaged with the to-be-engaged part, and

wherein one of the wall member and the to-be-engaged part of the flat member is an insert part and the other of the wall member and the to-be-engaged art of the flat member is a cut part, and the insert part is inserted in the cut part to secure the wall member to the flat member and thereby secure the bottom of the cushioning member.
