Abstract
Abstract A vented pouring spout formed of synthetic plastics material adapted to be retracted in stored position within a container opening and pulled up to extended pouring position for dispensing of the container contents. The spout is formed at its inner end with venting means for permitting the entry of air within the container through the pouring spout simultaneously with the liquid dispensing.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
129 words
A self-venting pouring spout adapted to be pulled up from a retracted stored position within a container to an extended pouring position comprising a substantially cylindrical upper body portion, a circumferential lip at the upper end of said body portion for supporting said spout in retracted position, a lower body portion terminating in a spout base having a lower edge, an annular baffle axially spaced from said spout lower edge and connected thereto by a plurality of axially extending feet forming a series of radially directed openings therebetween circumferentially spaced about said spout base and a central aperture located in said baffle whereby liquid is dispensed through said central aperture while venting air is simultaneously introduced through said spout in communication with one or more of said radial openings.
Claim 2
Dependent Claim
129 words
A self-venting pouring spout adapted to be pulled up from a retracted stored position within a container to an extended pouring position comprising a substantially cylindrical upper body portion, a circumferential lip at the upper end of said body portion for supporting said spout in retracted position, a lower body portion terminating in a spout base having a lower edge, an annular baffle axially spaced from said spout lower edge and connected thereto by a plurality of axially extending feet forming a series of radially directed openings therebetween circumferentially spaced about said spout base and a central aperture located in said baffle whereby liquid is dispensed through said central aperture while venting air is simultaneously introduced through said spout in communication with one or more of said radial openings.
Claim 3
Dependent Claim
129 words
A self-venting pouring spout adapted to be pulled up from a retracted stored position within a container to an extended pouring position comprising a substantially cylindrical upper body portion, a circumferential lip at the upper end of said body portion for supporting said spout in retracted position, a lower body portion terminating in a spout base having a lower edge, an annular baffle axially spaced from said spout lower edge and connected thereto by a plurality of axially extending feet forming a series of radially directed openings therebetween circumferentially spaced about said spout base and a central aperture located in said baffle whereby liquid is dispensed through said central aperture while venting air is simultaneously introduced through said spout in communication with one or more of said radial openings.
Claim 4
Dependent Claim
129 words
A self-venting pouring spout adapted to be pulled up from a retracted stored position within a container to an extended pouring position comprising a substantially cylindrical upper body portion, a circumferential lip at the upper end of said body portion for supporting said spout in retracted position, a lower body portion terminating in a spout base having a lower edge, an annular baffle axially spaced from said spout lower edge and connected thereto by a plurality of axially extending feet forming a series of radially directed openings therebetween circumferentially spaced about said spout base and a central aperture located in said baffle whereby liquid is dispensed through said central aperture while venting air is simultaneously introduced through said spout in communication with one or more of said radial openings.
