  • Patent number: 4674628
    Abstract: A portable pocket-size card holding device includes a holder capable of holding a plurality of cards. The holder comprises a pair of spaced floor and top members, laterally spaced side members extending between the floor and top members, and an end member extending between a first set of ends of the floor, top and side members so that the one end of the holder is closed off and its other end is open, with the members defining between them a cavity. Spaced channels are provided along the top and floor members. The channels are located inside the cavity and extend substantially parallel to one another, with the channels of the top member being aligned with those of the bottom members so that, in use, cards in the holder will extend substantially parallel to the side members. Each pair of channels in the top and floor members provides a card receiving zone capable of accommodating a single card.
