Cushioning material and packaging

A packaging comprising:

• a housing section having an opening, through which an object can be housed, wherein the housing section comprises a container that is made of a packing material selected from a group consisting of plastic, corrugated board, and glass fiber,
• a lid provided in the housing section and being capable of opening and closing the opening,
• a contact sensor connected to the lid, wherein the contact sensor is configured to detect an opening of the lid and a closing of the lid, and wherein the housing section has a cushioning material disposed in the inside thereof, and
• a check valve connected to the cushioning material and a hole in the housing section,
• wherein the cushioning material inflates and applies a predetermined pressure on an object in response to a first condition being satisfied, and deflates and releases the predetermined pressure on the object in response to a second condition being satisfied,
• wherein the check valve provides an inflow port and an outflow port to the cushioning material,
• wherein the check valve causes fluid to flow into the cushioning material in response to the contact sensor detecting that the lid is closed,
• wherein the check valve causes fluid to flow out of the cushioning material in response to the contact sensor detecting that the lid is open,
• wherein the first condition corresponds to the lid being closed, and
• wherein the second condition corresponds to the lid being opened.

A packaging, comprising:

• a housing section having an opening, through which an object is housed;
• a lid provided in the housing section and being capable of opening and closing the opening;
• and
• a variable body that is disposed inside the housing section with the object, the variable body inflating when a fluid flows thereinto and deflating when the fluid flows thereout,
• wherein the variable body is disposed on inner surfaces from a bottom portion to one side surface of the housing section, and partially on an inner surface of the lid,
• wherein the variable body forms a U-shaped cross section such that top and bottom surfaces and one side surface of the object are surrounded by the variable body and the object is supported while being applied to a predetermined pressure, when the lid is closed, and
• wherein the variable body deflates such that the predetermined pressure on the object is released, when the lid is opened.
