Abstract
An air-packing device has an improved shock absorbing capability to protect a product in a container box. The air-packing device is comprised of first and second thermoplastic films where predetermined portions are bonded thereby creating a plurality of air containers, a plurality of heat-seal lands each sealing the first and second thermoplastic films in a small area of the air container thereby creating a plurality of series connected air cells for each air container, a plurality of check valves for corresponding air containers for allowing the compressed air to flow in a forward direction. A bendable flap portion is created that facilitates opening and closing operations so that a product to be protected can be easily placed or removed.
Claims18
An air-packing device inflatable by compressed air for protecting a product therein, comprising:
- first and second thermoplastic films superposed with each other where predetermined portions of the first and second thermoplastic films are bonded, thereby creating a plurality of air containers;
- a plurality of heat-seal lands each sealing the first and second thermoplastic films in a small area of the air container in a manner to allow air flow between the air cells, thereby creating a plurality of series connected air cells for each air container;
- a plurality of check valves for corresponding air containers established between the first and second thermoplastic films for allowing the compressed air to flow in a forward direction;
- and
- an air input commonly connected to the plurality of check valves to supply the compressed air to all of the air cells through the check valves;
- wherein a part of a set of the air cells at one end of the air-packing device and a part of a set of the air cells at another end of the air-packing device are not bonded to create a top opening having a pair flap portions symmetrical with one another to open and close the air-packing device.

- an air input commonly connected to the plurality of check valves to supply the compressed air to all of the air cells through the check valves;
- and
- wherein a most part a set of the air cells at one end of the air-packing device is not bonded to create a top opening having a flap portion to open and close the air-packing device, and wherein an end of the flap portion comes under the air cells at another end when the air-packing device is closed.
