Abstract
An insert for use with a closed loop system, a dispensing system, a gravity draining system or other systems. The insert is designed to be inserted into the throat of a container such as a bottle. The insert includes a cylindrical seal which has a hardness which is less than the other components of the insert. The seal compensates for varying inside diameters of the throat of the container. The seal may be overmolded into a cylindrical recess formed in the insert or may be separately molded and then positioned in the cylindrical recess.

An insert for use with a closed loop system including
- a container having a throat with an inside surface, comprising:
- a horizontally disposed ring-shaped lip having an upper side, a lower side, an outer end, and an inner end;
- a cylindrical first wall member having an upper end, a lower end, an inner surface and an outer surface;
- said first wall member extending downwardly from said inner end of said lip whereby said lip protrudes outwardly from said upper end of said first wall member;
- an annular shoulder, having inner and outer ends, at said lower end of said first wall member;
- a second wall member, having an upper end and an open lower end, extending downwardly from said inner end of said shoulder;
- said open lower end of said second wall member having internal threads formed therein;
- a tubular member having upper and lower ends;
- said tubular member being positioned within said first and second wall members;
- said lower end of said tubular member being fixed to second wall member;
- said lip, said first wall member, said shoulder, said second wall member and said tubular member being injection molded with a plastic material having a first hardness;
- said outer surface of said first wall member having a cylindrical recess formed therein;
- and a seal having an upper end, a lower end, an inner side and an outer side;
- said seal being comprised of a plastic material which is positioned in said cylindrical recess in said outer surface of said first wall member after the other parts of the insert have been injected molded;
- said outer surface of said seal being downwardly and inwardly curved;
- said seal being comprised of a plastic material which has a hardness less than the said first hardness.
