Dispensing device with two-way flow characteristic and half twist closure

Claim 2

A dispensing device for a container comprising: a first member adapted to be disposed in a passageway of a content carrying container, said member having a generally tubular body with two sections, the first section including an internally extending thread and at least one externally extending relatively rigid flange, and the second section including internal means for forming a content passageway and a plurality of external relatively flexible flanges; and a second member adapted to cooperatively operate with said first member, said second member having two sections, a first section being generally tubular and having a smooth internal surface, a sealing end surface and an externally extending thread for engaging the internally extending thread of the first member and being moveable there along; and a second section having a funnel shaped surface contiguous with the smooth internal surface of said first section and an annular leg for forming an operating surface, said second member being moveable between a closed position in which said sealing end surface engages said internal passageway forming means for blocking the flow of content, and an opened position in which said second member is moved along said threads to disengage said sealing end surface and said passageway forming means to allow content flow; and said annular leg and funnel shaped surface intersect to form an edge, said annular leg including an annular concave surface adjoining said edge.

Claim 3

A dispensing surface as claimed in claim 1 wherein: said second section of said second member includes reinforcing ribs between said annular leg and that portion of the member forming said funnel shaped surface.

Claim 4

A dispensing device as claimed in claim 1 wherein: said sealing end surface includes a recess.

Claim 5

A dispensing device for a container comprising: a first member adapted to be disposed in a passageway of a content carrying container, said member having a generally tubular body with two sections, the first section including an internally extending thread and at least one externally extending relatively rigid flange, and the second section including internal means for forming a content passageway and a plurality of external relatively flexible flanges; a second member adapted to cooperatively operate with said first member, said second member having two sections, a first section being generally tubular and having a smooth internal surface, a sealing end surface and an externally extending thread for engaging the internally extending thread of the first member and being moveable there along, and a second section having a funnel shaped surface contiguous with the smooth internal surface of said first section and an annular leg for forming an operating surface, said second member being moveable between a closed position in which said sealing end surface engages said internal passageway forming means for blocking the flow of content, and an opened position in which said second member is moved along said threads to disengage said sealing end surface and said passageway forming means to allow content flow; said annular leg of said second member includes an inwardly directed projection; and said flange of said first member includes an outwardly directed projection whereby when said members are in said closed position said projections abut one another.

Claim 6

A dispensing device for a container comprising: a first member adapted to be disposed in a passageway of a content carrying container, said member having a generally tubular body with two sections, the first section including an internally extending thread and at least one externally extending relatively rigid flange, and the second section including internal means for forming a content passageway and a plurality of external relatively flexible flanges; a second member adapted to cooperatively operate with said first member, said second member having two sections, a first section being generally tubular and having a smooth internal surface, a sealing end surface and an externally extending thread for engaging the internally extending thread of the first member and being moveable there along, and a second section having a funnel shaped surface contiguous with the smooth internal surface of said first section and an annular leg for forming an operating surface, said second member being moveable between a closed position in which said sealing end surface engages said internal passageway forming means for blocking the flow of content, and an opened position in which said second member is moved along said threads to disengage said sealing end surface and said passageway forming means to allow content flow; said annular leg of said second member includes an inwardly directed projection; and said flange of said first member includes an outwardly directed projection whereby when said members are in said closed position said projections abut one another.

Claim 7

A dispensing device as claimed in claim 4 wherein said first member includes an airflow tube connected to said second section and positioned to extend into said container; said passage forming means includes a centrally disposed disc having an annular peripheral surface, said annular peripheral surface for engaging a portion of the smooth internal surface of said second member when in said closed position, and three passageways, two for content such as a liquid and one for air disposed about said disc, said air passageway communicating with said air flow tube; said annular leg and funnel shaped surface intersect to form an edge, said annular leg including an annular concave surface adjoining said edge; and said sealing end surface includes a recess.
