A dispensing device (e.g., a horn-shaped cup or holder, an irrigation bottle, or a device shaped like a tea pot with a bulbous tipped spout) used to apply a liquid treatment, usually a saline solution, directly to the nasal cavity via the nares, typically to clear and clean the mucous membrane and the nasal channels. Typically made of plastic or as a crockery vessel, the device may include a lid and separate base. It may be known as a nose horn because of its design or a Neti pot and is intended for home-use. This is a reusable device.
