A delivery device is for intermittently delivering materials such as liquids or gels over a sustained period of time to a surface in a controlled way. The surface mountable delivery device is capable of delivering, an antimicrobial agent to protect surfaces from microbial contamination and/or to disinfect surfaces, e.g. door handles, push plates, hand rails, etc. as an aid in preventing and/or hindering the spread of infectious agents. The device uses a vertically lapped nonwoven material as the storage medium for the liquid or gel like materials within the device. A non-wicking liquid mediating layer to controls transfer of liquid from a reservoir to a contact surface of the device to minimize liquid losses. An elastomeric contact liquid delivery layer is optimized for printability. Use of physical features at the device contact surface prevents pore occlusion on user contact and aids flow of liquid to the contact user.
