Abstract

According to one exemplary embodiment of the present invention, a center-pull bottom feed dispenser includes a housing defining a compartment and including a center-pull bottom feed arrangement for dispensing a sheet material that is in the form of a roll of the sheet material. The sheet material can be a pre-moistened airlaid web. The dispenser also includes a tray that supports the airlaid web roll and includes an outlet opening through which the airlaid web is fed to be accessible to a user. The tray includes a moisture retaining feature that directs fluid from the pre-moistened air-laid web away from the outlet opening and toward an outer peripheral edge of the roll.
