A dispensing device includes a housing at least partially surrounding a compressible container. The container includes a first tab member received by a first tab receiver in a wall of the housing. The dispensing device dispenses material through an open end of the container in response to a compressive force moving an opposing end of the container towards the open end. As the container is compressed, the first tab member exits the first tab receiver and enters a second tab receiver, which is located closer to the dispensing end of the housing than the first tab receiver. The first tab member remains in the second tab receiver after the compressive force has been removed.
