Abstract: A bag dispensing device comprises a box and a roll of bags, the bags being connected together in the roll. Each bag defines a dosed bottom end and an upper end that is dosed while the bag is part of the roll but that becomes open once the bag is detached from the roll. The roll of bags is located in the container with at least one leading bag thereof extending out of the container so as to be grasped by the user and detached from the roll when a bag is needed by the user for receiving therein a sample or the like.
