发明名称 Page protection system for photo albums and the like
摘要 A page protection system according to the present invention includes a band of material encircling the pages and a cover of an album, the band being snug enough to prevent removal of the pages without cutting or removing the band. In the most preferred embodiment of the present invention, the page protection system includes album ring elements secured to the back cover, rather than the spline of the album and a band made of transparent, synthetic, and heat sealable and/or heat shrinkable plastic material. The band should not be easily torn and not easily removable. It is preferably located near the rings, for example within about 1.5 inches from the ring elements if the elements are mounted to the spline of the album and adjacent the ring elements if they are mounted to an album cover.
