Cushioning structure for packed object

1 . A cushioning structure disposed inside a crate part of a packing frame surrounding a packed object, the cushioning structure being provided to protect the packed object secured on an inner bottom of the packing frame, the cushioning structure comprising:

a first cushioning member made of a foam material having a front face disposed adjacent to a side of the packed object;

a second cushioning member comprising a corrugated board assembly that supports the first cushioning member while being in contact with a back side of the first cushioning member;

a base part made of corrugated paper that is located to overlap inner sides of at least parts of two adjacent vertical frames among a plurality of vertical frames constituting the crate part of the packing frame, and has a front face to which a bottom of the second cushioning member supporting the first cushioning member is joined; and

an anchor part made of corrugated paper that is projected on a back side of the base part and is fit between the two vertical frames to fix the base part to the crate part.

2 . The cushioning structure according to claim 1 , wherein the cushioning structure is configured such that the base part has a length corresponding to a length from an upper end to a lower end of the two vertical frames in a vertical direction, and the base part has a lower end supported on the inner bottom of the packing frame.

3 . The cushioning structure according to claim 1 , wherein the anchor part includes a corrugated board laminate.

4 . The cushioning structure according to claim 1 , wherein the first cushioning member has an elongated shape extending & with a first width-in a longitudinal direction with a first width, and the second cushioning member has a bottom wall that forms a channel extending in the longitudinal direction with a second width larger than the first-width, a pair of side walls connected on both sides of the bottom wall via folding portions, and a plurality of bridge portions that bridge the pair of side walls at multiple points spaced at certain intervals in the longitudinal direction, and forms a channel extending in the longitudinal direction with a second width larger than the first width, wherein the first cushioning member is fixed on the second cushioning member while being in contact with upper ends of the bridge portions-in-a-range of the channel.

5 . The cushioning structure according to claim 4 , wherein the bottom wall and the pair of side walls of the second cushioning member are formed by a first corrugated cardboard blank such that a flute direction of the first corrugated cardboard blank is orthogonal to the longitudinal direction, and the plurality of bridge portions are formed by a plurality of second corrugated cardboard blanks such that a direction from the upper end to a lower end serves as a flute direction.

6 . The cushioning structure according to claim 1 , wherein the packed object is an outboard motor, and the packing frame is provided with a bracket on the inner bottom of the packing frame, and the bracket is configured to fix a stern bracket of the outboard motor-being fixed on a bracket with a propulsion direction of the outboard motor facing downward-by fastening a stem bracket of the outboard motor to the bracket provided on the inner bottom of the packing frame, and

the second cushioning member supporting the first cushioning member is diagonally positioned on the front face of the base part obliquely to an edge of the base part to be along a bottom cowl part of the outboard motor.
