Closure and pouring device for containers

Claim 2

In a closure device for a can or the like container, of the type comprising: a first part attachable to a can, and a second part relatively movable between a closed position and an open position to form a retractable pourer tube, the improvement wherein: said first and second parts are initially formed as a single body from resilient plastics material with said second part in said closed position and with a frangible connection therebetween foRming a guarantee seal of closure, said first and second parts being movable relative to each other after breaking of said frangible connection, an outer radial flange on said first part, an outer annular ridge on said first part, said ridge and said flange defining a recess therebetween whereby said first part is snap engageable to the rim of an opening in a wall of a can, a transverse closure wall on said second part, holder means on said transverse closure wall, openings in said second part to allow liquid to be poured out therefrom when said second part is moved to said open position by the application of an axial force to said holder means to rupture said frangible connection between said first part and said second part and extend said second part, first outer annular ridge means on said second part, abutment means on said first part, said first annular ridge means abutting said abutment means to define said open position of said second part, second outer annular ridge means on said second part, said second outer annular ridge means abutting said abutment means to define said closed position of said second part, said second part forming said pourer tube including: an outer tubular element, an inner tubular element coaxial with said outer tubular element and projecting from the upper end thereof, radial fins interconnecting said outer tubular element and said coaxial inner tubular element, said transverse closure wall being attached to the upper end of said coaxial inner tubular element whereby said openings in said second part are defined between said upper end of said outer tubular element, said radial fins, and the outer periphery of said transverse closure wall.

Claim 3

In a closure device for a can or the like container, of the type comprising: a first part attachable to a can, and a second part relatively movable between a closed position and an open position to form a retractable pourer tube, the improvement wherein: said first and second parts are initially formed as a single body from resilient plastics material with said second part in said closed position and with a frangible connection therebetween forming a guarantee seal of closure, said first and second parts being movable relative to each other after breaking of said frangible connection, an outer radial flange on said first part, an outer annular ridge on said first part, said ridge and said flange defining a recess therebetween whereby said first part is snap engageable to the rim of an opening in a wall of a can, a transverse closure wall on said second part, holder means on said transverse closure wall, openings in said second part to allow liquid to be poured out therefrom when said second part is moved to said open position by the application of an axial force to said holder means to rupture said frangible connection between said first part and said second part and extend said second part, first outer annular ridge means on said second part, abutment means on said first part, said first annular ridge means abutting said abutment means to define said open position of said second part, second outer annular ridge means on said second part, said second outer annular ridge means abutting said abutment means to define said closed position of said second part, said frangible connection between said first and second parts being formed by two semi-circular bands defined by weakened lines on either side thereof between said first part and said transverse closure wall of said second part, two opposed radial ribs defining the ends of said semicircular bands, respective upstanding stems on one end of each of said semicircular bands, an annular holder means supported by said stems, whereby said frangible connection between said first and second parts of said device may be broken by the application of an axial force to said holder means to tear off said semi-circular bands along sAid weakened lines and to extend said second part to said open position.

Claim 4

In a closure device for a can or the like container, of the type comprising: a first part attachable to a can, and a second part relatively movable between a closed position and an open position to form a retractable pourer tube, the improvement wherein: said first and second parts are initially formed as a single body from resilient plastics material with said second part in said closed position and with a frangible connection therebetween forming a guarantee seal of closure, said first and second parts being movable relative to each other after breaking of said frangible connection, an outer radial flange on said first part, an outer annular ridge on said first part, said ridge and said flange defining a recess therebetween whereby said first part is snap engageable to the rim of an opening in a wall of a can, a transverse closure wall on said second part, holder means on said transverse closure wall, openings in said second part to allow liquid to be poured out therefrom when said second part is moved to said open position by the application of an axial force to said holder means to rupture said frangible connection between said first part and said second part and extend said second part, first outer annular ridge means on said second part, abutment means on said first part, said first annular ridge means abutting said abutment means to define said open position of said second part, second outer annular ridge means on said second part, said second outer annular ridge means abutting said abutment means to define said closed position of said second part, said frangible connection between said first and second parts being formed by two semi-circular bands defined by weakened lines on either side thereof between said first part and said transverse closure wall of said second part, two opposed radial ribs defining the ends of said semicircular bands, respective upstanding stems on one end of each of said semicircular bands, an annular holder means supported by said stems, whereby said frangible connection between said first and second parts of said device may be broken by the application of an axial force to said holder means to tear off said semi-circular bands along sAid weakened lines and to extend said second part to said open position.

Claim 5

The closure device of claim 2 wherein said second part includes: a pourer tube element having a constricted zone at the upper end thereof and an outwardly turned radial lip, an inner tubular element coaxial with said pourer tube element and extending upwardly past the upper end thereof, said transverse closure wall of said second part being integrally formed with the upper end of said coaxial inner tubular element, and an annular transverse element substantially parallel to said transverse closure wall and spaced therefrom downwardly along said inner coaxial tubular element, said annular transverse element forming said second outer annular ridge means of said second part and acting to define said closed position of said device by abutting against said abutment means of said first part when said second part is retracted.
