Package and buffer tool

A package comprising:

• a storage portion configured to store an object;
• and
• a buffer portion configured to (1) be received in the storage portion and (2) reduce a gap between the object and an internal surface of the storage portion in a stacking direction of the buffer portion and the object when the buffer portion and the object are in the storage portion and the storage portion is in a closed state;
• wherein
• the storage portion includes a bottom and a lid facing the bottom,
• the buffer portion includes a base configured to face the object in the storage portion, a first fold adjacent an edge of the base, and a space adjusting portion connected to the base by the first fold,
• the first fold is configured such that the buffer portion is bendable between the base and the space adjusting portion at the first fold,
• the space adjusting portion includes a plurality of second folds distributed in a first direction intersecting the first fold, the plurality of second folds being spaced in the first direction between the first fold and a free end edge of the space adjusting portion opposite the first fold,
• the plurality of second folds are configured such that the space adjusting portion can be variably divided into an adjusting region, to adjust a height of the buffer portion in the stacking direction, and a contact region by bending the space adjusting portion at each of the plurality of second folds, the each of the plurality of second folds defining a boundary between the contact region and the adjusting region,
• the adjusting region has a first edge at the first fold and a variable second edge at the each of the plurality of second folds,
• the contact region includes the free end edge of the space adjusting portion,
• the storage portion and the buffer portion are configured such that a lowermost surface of the buffer portion in the stacking direction and the bottom define a space to store the object when the buffer portion and the object are in the storage portion and the storage portion is in the closed state, and
• the buffer portion is configured such that, when (1) the object and the buffer portion are stacked on the bottom to be stored in the storage portion, (2) the buffer portion is bent between the base and the space adjusting portion at the first fold, and (3) the each of the plurality of second folds defines the boundary between the contact region and the adjusting region, a sum of a height of the adjusting region and a height of the object in the stacking direction is approximately equal to a height from the bottom to the lid in the stacking direction.
