Abstract

The invention relates to a container assembly comprising a container part with a circumferential wall and a bottom wall, and a lid part comprising a connection portion for connection to a rim of said circumferential wall and a lid which is pivotably connected to said connection portion, said connection portion comprising an upper wall provided with an access opening which can be sealed with said lid, and said connection portion is provided with stacking provisions which enclose said access opening and which are complementary with stacking provisions at the bottom of said container part.

First claim

The invention claimed is:

1. A container assembly for a powdered nutritional product, the container assembly comprising:
a container part with a circumferential wall and a bottom wall; and
a lid part comprising a connection portion for connection to a rim of said circumferential wall and a lid which is pivotably connected to said connection portion, said connection portion comprising an upper wall provided with an access opening which can be sealed with said lid, and said connection portion is provided with stacking provisions which are provided around said access opening and which are complementary with stacking provisions at the bottom of said container part,
wherein said lid part has a weight of between 5 g and 500 g, an area of said access opening is at least 50% of the area of the connection portion, said access opening is surrounded by a circumferential first flange and said lid comprises a central portion having an underside including a clamp for holding a metering scoop for the powdered nutritional product and a circumferential lid flange surrounding the central portion and extending towards said connection portion, a radially innermost perimeter of said lid flange and a radially outermost perimeter of said first flange being mutually adapted to directly engage each other to allow said lid to close in a sealing manner around said first flange of said connection portion, said lid being connected to said connection portion via an integrated hinge which has a connection part connecting to a lower end of said lid flange, the lower end being directly adjacent to said upper wall when said lid is closed, and said lid is provided with a lip for opening the lid, which lip is provided at said lower end of said lid flange, and
wherein the circumferential lid flange defines a cylindrical space, the circumferential lid flange defines an outermost portion of the lid, and the central portion comprises a recessed dome, located in an interior of the circumferential lid flange, defined by said cylindrical space and having a highest point at a centre of the lid.

2. The container assembly of claim 1 , wherein said access opening has an area of at least about 50 cm 2 to about 200 cm 2 .

3. The container assembly of claim 1 , wherein said stacking provisions on said connection portion comprise cams, and the circumferential wall of the container part extends downwards beyond the bottom wall and is sized to locate around an outside of the cams of a similar container assembly.

4. The container assembly according to claim 3 , wherein said cams are positioned at corners of a rectangle which are provided around said lid when sealing said access opening.

5. The container assembly according to claim 3 , wherein the height of said cams is at least the height of said lid when sealing said access opening.

6. The container assembly according to claim 1 , wherein said connection portion comprises a circumferential rim for receiving an upper edge of a side wall of said container part in a groove, the inner perimeter of said rim being complementary to the perimeter enclosing said stacking provisions of said lid part for providing complementary stacking means for stacking a series of lid parts.

7. The container assembly according to claim 1 , wherein said lid part is substantially made from a thermoplastic material and comprising a connection portion for connection to a rim of a container part and a lid which is pivotably connected to said connection portion, said connection portion comprising an access opening and a circumferential first flange surrounding said access opening, said lid comprising a circumferential lid flange extending towards said connection portion, perimeters of said lid flange and of first flange mutually adapted to allow said lid to close in a sealing manner on said first flange of said connection portion, and an area of said access opening is at least about 50 cm 2 .

8. The container assembly according to claim 1 , wherein said lip is provided with an end rim which extends to a periphery of the connection portion.

9. The container assembly according to claim 8 , wherein said connection portion is provided with a tamper evident strip which blocks the lip.

10. The container assembly according to claim 9 , wherein said tamper evident strip has holes and blocking ends of said lip extend radially through said holes to provide a visible indication.

11. A lid part for a container assembly, said lid part comprising:
a connection portion for connection to a rim of a circumferential wall; and
a lid which is pivotably connected to said connection portion, said connection portion comprising an upper wall provided with an access opening which can be sealed with said lid, and said connection portion is provided with stacking provisions which are provided around said access opening,
wherein said lid part has a weight of about 5-500 gr, an area of said access opening is at least 50% of the area of the connection portion, said access opening is surrounded by a circumferential first flange and said lid comprises a central portion having an underside including a clamp for holding a metering scoop for a powdered product and a circumferential lid flange surrounding the central portion and extending towards said connection portion, a radially innermost perimeter of said lid flange and a radially outermost perimeter of said first flange being mutually adapted to directly engage each other to allow said lid to close in a sealing manner around said first flange of said connection portion, said lid being connected to said connection portion via an integrated hinge which has a connection part connecting to a lower end of said lid flange, the lower end being directly adjacent to said upper wall when said lid is closed, and said lid is provided with a lip for opening the lid, which lip is provided at said lower end of said lid flange, and
wherein the circumferential lid flange defines a cylindrical space, the circumferential lid flange defines an outermost portion of the lid, and the central portion comprises a recessed dome, located in an interior of the circumferential lid flange, defined by said cylindrical space and having a highest point at a centre of the lid.

12. The lid part of claim 11 , wherein said lid part is substantially made from a thermoplastic material.

13. The lid part of claim 11 , wherein an area of said access opening is at least about 50 cm 2 .

14. A package comprising the container assembly of claim 1 and further comprising a quantity of the powdered nutritional product within the container part.

15. The container assembly of claim 2 , wherein said stacking provisions on said connection portion comprise cams.

16. The container assembly according to claim 4 , wherein the height of said cams is at least the height of said lid when sealing said access opening.

17. The lid part of claim 12 , wherein an area of said access opening is at least about 50 cm 2 .

18. The container assembly according to claim 1 , further comprising a metering scoop, the metering scoop being engaged by the clamp at the underside of the lid.

19. The lid part according to claim 11 , further comprising a metering scoop, the metering scoop being engaged by the clamp at the underside of the lid.

20. The package according to claim 14 , further comprising a sealing foil attached to the inner surface of the circumferential wall of the container part below the rim.

21. The container assembly of claim 1 , wherein said lid part has a weight of between 5 g
