Abstract
Containers for products such as glue sticks are provided. The containers include a valve and a mechanical device for advancing a product through the container and for opening the valve. The mechanical device includes a screw component having a base portion and a threaded portion, a valve lifter component selectively slidable between a retracted position, in which the valve is closed, and alternatively an extended position, in which the valve is open, a biasing element that engages and applies force to the valve lifter component, and an elevator component for advancing the product through the container.
