Abstract
Abstract A flexible bag is adapted to contain articles to be dispensed, and the bag has a closed first end and open second end. A collar is fixed to the open second end of the bag. A top has therein a dispensing opening and a slit connected with the dispensing opening. The top is selectively movable between a first position fitted to the collar and a second position removed from the collar. A lid is selectively movable between a first position covering at least a portion of the top and a second position removed from the top. The lid includes a first portion adapted to cover the dispensing opening when the lid is in the first position thereof and a second portion adapted to cover the slit when the lid is in the first position thereof. The second portion of the lid is integrally but flexibly connected to the first portion of the lid, such that when the lid is in the first position thereof the second portion of the lid may be selectively pivoted with respect to the first portion of the lid away from the top, thereby to uncover the slit.
