Abstract
A method of packaging a self-inflating air mattress comprising an open cell foam core and an air impervious envelope. A plurality of mattresses are stacked intermittently between forming boards and evacuated. Each bag is then rolled up and placed in a flexible tubular container and the vacuum released on the mattress to provide a sung package. To remove the mattress, the container and mattress are compressed, the inflating valve closed, and the mattress slipped from the container.
Claims10
A method of packaging a self-inflating air mattress having an open cell foam core, an air impervious envelope, and an inflating valve, said method comprising:
- a. rolling the air mattress in an evacuated condition into a compact rolled-up configuration,
- b. placing said rolled-up mattress in a tubular container, while maintaining its evacuated condition, and
- c. releasing the interior of the mattress to atmospheric pressure to cause the mattress to expand moderately to fit snugly in the container.
A method of removing a self-inflating air mattress, having an open cell foam core, from a tubular container, where the air mattress has a snug fit in said container so as to be in frictional engagement therewith, said method comprising:
- a. applying a compressive force to the packaged air mattress, with the valve of the air mattress being opened, so that air is pushed from the interior of the air mattress,
- b. then closing the valve, and
- c. removing the mattress axially from said tubular container.
