Abstract: A display package having a housing containing a plurality of slidably engaged trays that are selectively extended from or retracted into the housing by a linkage assembly comprising a rotatable drive wheel, and a plurality of drive arms each rotatably connected to the drive wheel and to an associated tray through an elongated guide slot in a divider adjacent to each drive arm, the elongated guide slot being generally parallel to the direction in which extension or retraction of the associated tray is desired, with the length of the elongated guide slot limiting the rotation of the drive wheel.

Abstract: A tamper-resistant plastic package having a plastic sleeve with at least one open end into which a product carrier tray, also made of plastic, can be inserted into sliding and interlocking engagement with the sleeve. The sleeve desirably comprises a continuous side wall having sufficient length and cross-sectional area to receive the product carrier tray into sliding engagement therewith. The product carrier tray is preferably thermoformed from another plastic sheet made of the same or a different plastic material. The plastic sheets used to make the sleeve and product carrier tray each preferably further comprise one or more structural elements, as described in greater detail below, that cooperate to provide a mechanical interlock when the product carrier tray is fully inserted into the sleeve.
