Abstract
A liquid dispenser (10) for a container of liquid, comprises a spout (12) and a liquid uptake structure (18) aligned to provide liquid to the spout from a container. The liquid uptake structure has first openings (20) radially distributed at the spout end, second openings radially distributed around the container end and a third opening centrally located at the container end. The liquid uptake structure provides an airflow path through the second openings and a principle liquid flow path separate from the airflow path through the third opening, thus separating the two flow paths and providing a smooth pour.
Claims15
A liquid pourer for a container of liquid, comprising:
- a telescopic spout;
- and
- a liquid uptake structure aligned to provide liquid to said spout, said liquid uptake structure having a first end towards said spout and a second end towards a depth of said container, the structure comprising:
- cylindrically distributed extensions extending downwardly from said first end and terminating prior to reaching said second end, and having first openings extending downwardly between said extensions, said first openings thereby forming slits, said first openings being open towards said second end to form a second, circumferential opening;
- a ring located radially inwardly of said extensions and beyond said terminating, said ring forming a third opening within said ring at said second end, the liquid uptake structure thereby to provide an airflow path through said first openings and said second opening and a principle liquid flow path separate from said airflow path through said third opening;
- said ring defining a radial separation between said airflow path and said liquid path, said separated airflow path surrounding said liquid path and extending towards said extensions and said gaps;
- and
- a rim for fixing onto an opening in a container.
A method of manufacturing a liquid pourer for smoothly dispensing liquid from a container via a single opening, the method comprising:
- providing a liquid path for passage of liquid centrally through said pourer;
- providing an air path for passage of air and bubble formation radially outwardly of said liquid path, the air path comprising a cylinder surrounding said liquid path and having airflow openings radially distributed in said cylinder between extensions at an upper end, the extensions terminating prior to reaching a lower end, the air path being separated from said liquid path by a ring at said second end, the ring being radially inwardly of said extensions and providing a radial thickness between said air path and said liquid path and further defining a circumferential opening between said ring and a point at which said extensions terminate, said airflow openings opening out into said circumferential opening;
- and
- providing a rim for fitting onto said opening in said container, said rim being continuous with said cylinder and said extensions.
