Abstract
Abstract A package for an intrauterine device-intrauterine device inserter combination and a "pillow pack" carton for the package are disclosed. The package consists of three elements: (1) a thermoformed plastic tray having an elongated, relatively deep cavity for holding the combination, a convexly curved marginal ledge about the cavity, an end wall extending downwardly from each end of the ledge, and a flange extending outwardly from the bottom of each end wall; (2) a cover that fits over the cavity and has the same curvature as the marginal ledge; and (3) an adhesive coating on the inner side of the cover by which the cover is attached to the ledge over the cavity. The package is enveloped in a paper carton that has a bottom wall on which the package bottom rests, a pair of end walls, each of which has an inwardly extending section that overlies one of the flanges of the package tray whereby the package is held firmly in place, and a pair of flaps that are foldably connected to the longitudinal edges of the bottom wall and fold over the top of the package in an overlapping, interlocking fashion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
228 words
A cartoned medical instrument package comprising in combination: a. a package comprising: i. a thermoplastic tray having a cavity for holding the instrument, a convexly curved marginal ledge about the cavity extending outwardly from the opening of the cavity and defining the top surface of the tray, an end wall extending downwardly from each end of the ledge, and a flange extending outwardly from the bottom of each end wall, ii. a cover for said cavity, and iii. means for adhesively securing the cover to said ledge about the complete perimeter of the cavity such that the cover may be peeled away to expose the cavity; and b. a carton adapted to envelop the package completely comprising: i. a bottom wall against which the bottom of the package rests, ii. a pair of single piece end walls, each of which is foldably connected to the bottom wall and has an inwardly extending section that overlies one of the flanges of the tray of the package whereby the package is held firmly in place in the carton, iii. a first flap foldably connected to an opposite edge of the bottom wall, said first and second flaps adapted to fold over the top of the package in overlapping relationship to each other, and v. means for releasably interconnecting said first and second flaps while they are in said overlapping relationship.
