Abstract
An elongated pouring spout is provided incorporating relatively rotatable inner and outer tubular members which are longitudinally shiftable and relatively rotatable relative to each other. The spout includes inlet and outlet ends and the outlet end of the outer tubular member is closed by an end wall and includes a plurality of peripherally spaced and radially outwardly opening ports formed therein adjacent the end wall. The outlet end of the inner tubular member is open and includes a beveled (innerside) end edge sealingly seatable in a circumferential groove formed in the inner surface of the end wall and the inlet end of the inner tubular member projects outward of the inlet end of the outer tubular member. Further, the inlet end of the spout defines a pin and slot connection between the inner and outer tubular members whereby relative rotational oscillation of the inner and outer tubular members will cause relative longitudinal reciprocation thereof.

5402920 - No spill container

A no spill container including a bottle having a threaded neck for attaching to a threaded cap. The cap includes a conical stopper and a flared skirt extending inward on the bottle. The inward end or hem of the skirt provides a gripping surface away from the neck of the bottle for opening and closing the cap. The neck includes an opening to receive the stopper when the cap is closed. An aperture is formed in the cap. When the cap is open, fluid in the container flows into the neck opening and is discharged from the aperture. When the cap is closed the stopper extends inside the neck opening and the outer end of the neck closes the aperture in the cap, to thereby prevent fluid flow out from the container.

4979655 - Pouring fitment

A pouring assembly or fitment for pouring material from a container in an inverted position comprises a tube having a first end for attachment to the open end of the container and a second end having a dispensing opening for dispensing material from the tube, and a closure sleeve fitting over the second end of the tube and movable relative to the tube between a first position in which the dispensing opening is blocked and a second position in which the dispensing opening is open. The closure sleeve has a closed first end, a cylindrical portion extending from the first end for closely fitting over the second end of the tube, and an outwardly tapering conical portion extending from the cylindrical portion to the second end of the sleeve, which acts as a rest for positioning the assembly on oil fill openings of varying dimensions.

6702160 - No spill container

The invention discloses a no spill container where the user can properly position the dispensing port and release the contents of the container by means of a release assembly integral with the cap of a displacement port. The contents are released when the cap of the displacement port is rotated into an open position and the integral release stem lifts the sealing means that is adjoined to the stem on the opposite end at the dispensing port. The lifting of the stem causes the sealing means at the dispensing port to disengage from the dispensing port allowing the contents of the container to be expelled.
