Abstract

A tip (10) for the dispensing of materials includes a housing (11) having first and second chambers (12, 13) contained therein. The chambers (12, 13) communicate with a mixing reservoir (19) and a hollow barrel (21). The hollow barrel (21) has an output orifice (51) and is in fluid communication with the mixing reservoir (19). Disposed within hollow barrel (21) is a static mixing device (30).

Claims

1. A tip for the dispensing, mixing and application of a material having first and second components to be mixed prior to application comprising a housing, first and second chambers disposed within said housing and in communication, said chambers providing a means to attach said mixing tip to a preloaded cartridge fluidly communicating with a mixing reservoir, a dispensing barrel having a hollow interior also in fluid communication with said mixing reservoir and having an output orifice, a static mixing device disposed within said barrel, said static mixing device comprising a twisted wire component.

2. A tip as in claim 1 wherein static mixing device is also provided with a brush at least partially protruding from said barrel.

3. A tip as in claim 1 wherein said barrel and said enclosed static mixing device can be bent at an angle.
