Abstract
A dispensing tip or tool for use in dispensing a caulking or liquid sealant in conjunction with caulking guns or similar tools. The tip flattens in cross-section towards the dispensing end, with a rectilinear opening causing the liquid sealant to emerge at a specific thickness and width. A pair of guide tabs cause the sealant to emerge and be placed over a gap, seam or joint to be sealed. A fin extending from the bottom fits within the seam, gap or joint to help guide the tool during use. A notch in the bottom side of the opening allows for more sealant flow into the seam, gap or joint itself.
