ABSTRACT:
A multiple package unit consisting of a plurality of packages of mechanical pencil refill leads is formed of first and second sheet materials. The first sheet material includes a plurality of integral parallel sections each shaped to provide an elongated swelling on one side, a corresponding recess in the other side and a substantially flat marginal flange integral with the swelling and extending outwardly therefrom. The sections of the first sheet material form separable containers, respectively. Refill leads are housed in the recess in each container. The second sheet material includes a plurality of flat and integral sections each extending over a recess in one of the containers and secured to the marginal flange thereof to form a closure of the container. Each container cooperates with the leads therein and with associated closure member to form a package which is separable from an adjacent package by means of score line formed in at least the first sheet material. Each container is provided with a weakening cut formed in the swelling adjacent to one end thereof to facilitate opening of the package.
