- 6. The pouring spout attachment described in claim 5, characterized by said detent element being a projection from said inner surface of said body, and said hinge connection providing a pivot portion between said forward and rearward portions.
- 7. The pouring spout attachment described in claim 6, wherein said end wall defined by said first and second cuts is adapted to pivot about said hinge connection when a downward farce is applied adjacent the first cut end of the web segment, causing the further cut end of the end wall to be pivoted upwardly about said pivot portion in a fulcrum and lever effect to snap past said internal projection and be retained thereby.
- 8. A pouring attachment for attaching to a wall of a container, comprising an inner body in the form of a flap, an outer body bounding a pouring zone and extending around said flap, and hinge means nearer one side of said pouring zone than the opposite side of said pouring zone, and mounting said flap in said outer body for turning, about an axis extending transversely of said outer body, between a flow-obturating position in said pouring zone and a flow-enabling position, and a detent on said outer body characterized in that said detent is nearer said one side than said opposite side and said flap has an upwardly pivotable portion adapted to engage said detent, whereby said flap is retained in said flow-enabling position following turning of said flap from said flow-obturating position to said flow-enabling position.
- 9. An attachment according to claim 8, wherein a through-cut is formed between adjacent inner and outer peripheral edges of said outer body and said flap, respectively.
- 10. An attachment according to claim 8, wherein a partial-depth cut is formed between adjacent inner and outer peripheral edges of said outer body and said flap, respectively.
- 11. An attachment according to claim 8, wherein said flap comprises a major part at one side of said axis and a minor part at another side of said axis and wherein said minor part serves to engage said detent on its upward movement to retain said flap in said flow-enabling position.
- 12. An attachment according to claim 11, wherein said minor part is substantially co-planar with said major part.
- 13. An attachment according to claim 11, wherein said minor part is inclined to said major part.
- 14. An attachment according to claim 13, wherein said outer body includes a pocket defined by said detent and serving to receive said minor part in said flow-enabling position of said flap.
- 15. An attachment according to claim 14, wherein said outer body includes a tubular part encircling said pouring zone and closed at one end by a web comprised of said major part and a wall of said pocket, said hinge means being at a junction between said major part and said wall of said pocket, and a line of weakness extending along a junction between said tubular part and said major part and being frangible to permit turning of said flap about said hinge means from said flow-obturating position towards said flow-enabling position.
- 16. A combination comprising:
- (i) a container having a wall, and
- (ii) a pouring device at the outside of said wall and comprising an inner body in the form of a flap, an outer body bounding a pouring zone and extending around said flap, which occupies a flow-obturating position in said pouring zone, hinge means nearer one side of said pouring zone than the opposite side of said pouring zone, and mounting said flap in said outer body for turning about an axis extending transversely of said outer body, between said flow-obturating position in said pouring zone and a flow-enabling position, and a detent on said outer body, characterized in that said detent is nearer said one side than said opposite side and said flap has an upwardably pivotable portion adapted to engage said detent, whereby said flap is retained in said flow-enabling position following turning of said flap from said flow-obturating position to said flow-enabling position.
- 17. A combination according to claim 16, wherein a through-cut is formed between adjacent inner and outer peripheral edges of said outer body and said flap, respectively, and a weakened, but imperforate, portion of said wall is present in said pouring zone.
- 18. A combination according to claim 16, wherein a partial-depth cut is formed between adjacent inner and outer peripheral edges of said outer body and said flap, respectively, and an opening is formed through said wall in said pouring zone.
- 19. A combination according to claim 16, wherein said flap comprises a major part at one side of said axis and a minor part at another side of said axis and wherein said minor part serves to engage said detent on its upward movement to retain said flap in said flow-enabling position.
- 20. A combination according to claim 19, wherein said minor part is substantially co-planar with said major part.
- 21. A combination according to claim 19, wherein said minor part is inclined to said major part.
- 22. A combination according to claim 21, wherein said outer body includes a pocket defined by said detent and serving to receive said minor part in said flow-enabling position of said flap.
- 23. A combination according to claim 22, wherein said outer body includes a tubular part encircling said pouring zone and closed at its outer end by a web comprised of said major part and a wall of said pocket, said hinge means being at a junction between said major part and said wall of said pocket, and a line of weakness extending along a junction between said tubular part and said major part and being frangible to permit turning of said flap about said hinge means from said flow-obturating position towards said flow-enabling position.
- 24. A pouring attachment for attaching to a wall of a container, comprising an inner body in the form of a flap, an outer body surrounding a pouring zone and extending around said flap, and hinge means nearer one side of said pouring zone than the opposite side of said pouring zone, and mounting said flap and said hinge means within said outer body for turning about an axis of said hinge means extending transversely of said outer body, between a flow-obturating position in said pouring zone and a flow-enabling position, and a detent formed on said outer body nearer one end than the opposite end of said pouring zone, and said flap has a portion adjacent said one end of said pouring zone adapted to engage said detent on said outer body, whereby said flap is retained in said flow-enabling position following turning of said flap from said flow-obturating position to said flow-enabling position.
