Abstract
A pour spout adapter comprises a housing, a collar and a threaded engagement. The housing has a sealed bore for receiving a tube. The collar has an internal bore coupled to the housing at a rotatable connection so as to permit a tube to extend from the sealed bore through the collar. The threaded engagement is disposed on the internal bore to receive a threaded pour spout.
Claims26
A pour spout adapter assembly comprising:
- a cylindrical housing extending from a first axial end to a second axial end, the cylindrical housing comprising:
- an inlet bore extending from the first axial end to the second axial end;
- a return bore extending from the first axial end to the second axial end;
- a vent passageway configured to allow air to pass through the housing and into a fluid container, the vent passageway comprising:
- a vent bore extending into the housing between the first axial end and the second axial end;
- and
- a vent passage that intersects the first vent bore and extends to the second axial end of the housing;
- a cap located at the first axial end of the housing to seal against the inlet and return bores;
- and
- a threaded collar rotatably joined to the second axial end of the housing and including internally located threads configured to allow the housing to be connected to a fluid container at a threaded pour spout.
