Abstract: A resealable envelope comprising a flexible plastic back sheet, a backing adhesive applied on a back surface of the flexible plastic back sheet to attach the envelope to a package, a flexible plastic front sheet attached to the back sheet at their respective side edges and bottom edges, a flexible closure flap being adhered directly to the front surface of the back sheet at their respective top edges via a permanent adhesive and overlapping said front sheet, and a resealable adhesive located proximal to the top edge of the front sheet such that the resealable adhesive is capable of fastening said closure flap to the front sheet forming a resealable closure.

Abstract: A printer which comprises a printing roll mounted upon a main shaft for rotation, an ink roll presented in axial parallel relationship to said printing roll and having heat-soluble ink, a clutch brake unit operatively connected to said printing roll and ink roll for controlling rotation thereof consonant with the printing interval of material to be printed responsive to a feeding mechanism, an encoder for translating the rate of speed of said material into a pulse of unit length. A heat sleeve is concentrically disposed upon said main shaft for rotation therewith; there being a heater element provided within said heat sleeve. A printing type holder is removably mounted on the outer periphery of said heat sleeve for receiving ink from said ink roller. A power supply shaft cooperates with said feed mechanism, and a quill shaft is provided for operative connection to said power supply shaft to transmit rotation to said printing roll and ink roll.
