ABSTRACT:
A tamper-proof binder has a C-shaped rectangular spine into which a plurality of clear plastic envelopes carrying photographs or the like are secured. The envelopes are permanently sealed on three side edges and open only on one side which is secured in the spine to prevent the photos from being removed. The spine has an upper T-shaped longitudinal slot on the underside of the top wall and a lower longitudinal slot on the top side of the bottom wall and a counterbored hole extends through the bottom wall into the lower slot. The envelopes have holes spaced along the open side edge which receive a headed fastener for each hole. The heads of the fasteners are slidably received in the T-shaped slot of the spine and the shafts of the end fasteners are received in the lower slot at the bottom of the spine. A center fastener is a permanent two-part fastener with a head at both ends and the shaft portions engage each other to prevent the fastener from being pulled apart after being pressed together. The head of one piece of the two-piece fastener is slidably received in the T-shaped slot and the other headed piece is received in the hole at the bottom of the spine and the pieces are pressed together. Thus, a plurality of envelopes containing photographs and the like are sealed on all three exposed sides and are substantially "permanently" secured in the spine to prevent unauthorized removal of the photos or the envelopes.
