Estimating the term…
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. In one arrangement the device utilises a foam based reservoir in combination with a nonwoven fabric wicking layer and an elastomeric liquid delivery contact layer having valve like pore and/or slits; the combination provides for control of material delivery and longevity for the device in use.
A delivery device, comprising a reservoir in communication with an elastic liquid delivery contact layer, the elastic liquid delivery contact layer formed of a material having a plurality of closed valve like slits and/or pores extending there through and wherein there is a pre-strain of 0.2% - 5% of the relevant dimension in the contact layer in a direction parallel to the slit length after its integration into the device.
