A delivery device is described 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, for example, 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 preferred device has a number of aspects;; use of a vertically lapped nonwoven material as the storage medium for the liquid or gel like materials within the device, use of a non-wicking liquid mediating layer to control transfer of liquid from a reservoir to a contact surface of the device in order to minimize liquid losses, an elastomeric contact liquid delivery layer optimized for printability and the use of physical features at the device contact surface to prevent pore occlusion on user contact and to aid flow of liquid to the contact user. |
