  • Patent number: 4054204
    Abstract: An article fabricated from a flexible foam material, such as foam rubber, is compressed by encasing the article in a substantially air-tight sack, and withdrawing air from the sack, thereby reducing the size of the foam article for packaging. The article may be a fabric or plastic covered object, such as a pillow or toy animal; after compression, the object is packaged in a box. The packaged article provides an unusual gift item.
