a reusable package and storage album displays and stores a multi - component product , combining the appearance of a blister pak with the security of a vacuformed clamshell package . two sections joined by hinges to a spine , formed principally of plastic and paperboard materials , fold into a book or album - like structure to house the product components . ample advertising space is available on the exterior and interior surfaces for a layer of printed matter . the album type storage is helpful , discourages disposal of the packaging , which aids the environment , and allows manufacturer advertising and other printed information to persist beyond the sale . hinges comprise an inverted rectangular u - shape in section in geometry . windows may be included to allow a view of the components . a window formed in one album section may be recessed to also prevent a component in the other album section from flopping about when handling the package .
