Abstract

A dispensing cover (10) for use with a first fiberboard drum (14) includes a main portion (50), a skirt portion (52) and a skirt portion extension (54). The drum has a continuous upstanding drum wall (44) with a wall edge (46) having a rolled-in lip (16). The wall edge (16) forms a perimeter of a cover receiving opening (48). Main portion (50) is sized to fit within the perimeter of cover receiving opening (48). Skirt portion (52) is secured to main portion (50) and extends generally parallel to upstanding drum wall (44). Skirt portion extension (54) is secured to skirt portion (52) and forms a cavity (56) for receiving rolled-in lip (16) of drum (14). At least one barb (12) can be provided to secure cover (10) to fiberboard drum (14). A resealable lid (20) and a dispensing cover seal (30) can also be provided. The seal (30) prevents undesirable retention of product by the rolled-in lip (16). A stack alignment lip (42) can be provided to allow stacking of adjacent drums (14), (36).

Claims

1. A dispensing cover for use with a first fiberboard drum, the first fiberboard drum having a continuous upstanding drum wall with a wall edge having a rolled-in lip, the wall edge forming a perimeter of a cover-receiving opening, said dispensing cover comprising:

a main portion sized to fit within the perimeter of the cover-receiving opening;

a skirt portion which is secured to said main portion and which extends generally parallel to the upstanding drum wall;

a skirt portion extension which is secured to said skirt portion and which forms a cavity for receiving the rolled-in lip of the first fiberboard drum; and

at least one barb which is secured to said skirt portion and which extends outwardly therefrom, said barb having an angled surface which rides up and over the rolled-in lip of the first fiberboard drum as said dispensing cover is inserted in the first fiberboard drum, said barb having a generally straight surface which traps the rolled-in lip of the first fiberboard drum in said cavity of said skirt portion extension when said dispensing cover is fully inserted in the first fiberboard drum, said generally straight surface and said rolled-in lip of the first fiberboard drum interacting to permanently attach said dispensing cover to said first fiberboard drum.

2. A dispensing cover as defined in claim 1, wherein said main portion is formed with a lid-receiving aperture, further comprising a lid which is configured to be resealably secured in said aperture.

3. A dispensing cover as defined in claim 1, further comprising a dispensing cover seal formed of a flexible material, said seal being secured to said main portion, said seal having an outer perimetric seal edge which sealingly abuts the continuous upstanding drum wall when said dispensing cover is inserted in the first fiberboard drum, said seal being positioned to impede retention, by the rolled-in lip, of product contained in the first fiberboard drum.

4. A dispensing cover as defined in claim 3, wherein:

said main portion has a bottom face;

said barb extends no lower than said bottom face; and

said dispensing cover seal is a generally planar sheet having an upper surface secured to said bottom face of said main portion.

5. A dispensing cover as defined in claim 4, further comprising a tamper evident seal sheet interposed between said dispensing cover seal and said bottom face of said main portion to initially seal said lid-receiving aperture.

6. A dispensing cover as defined in claim 4, wherein:

the continuous upstanding drum wall forms a generally rectangular tube with rounded corners;

said dispensing cover seal is generally rectangular with rounded corners; and

said dispensing cover seal is formed with angled slits in said rounded corners to aid in flexible engagement of said dispensing cover seal with the first fiberboard drum.

7. A dispensing cover as defined in claim 3, wherein said main portion is formed with a lid-receiving aperture, further comprising a lid which is configured to be resealably secured in said aperture.

8. A dispensing cover as defined in claim 3, for stacking use with a second fiberboard drum having a recessed floor retained by rolled-in edges, said dispensing cover further comprising:

a stack alignment lip extending upwardly from said main portion to engage the rolled-in edges of the second fiberboard drum when the second fiberboard drum is stacked on top of said dispensing cover.

9. A dispensing cover as defined in claim 8, wherein said stack alignment lip is formed as a vertical extension of said skirt portion.

10. A dispensing cover as defined in claim 8, wherein said main portion is formed with a lid-receiving aperture, further comprising a lid which is configured to be resealably secured in said aperture.

11. A dispensing cover for use with a first fiberboard drum, the first fiberboard drum having a continuous upstanding drum wall with a wall edge having a rolled-in lip, the wall edge forming a perimeter of a cover-receiving opening, said dispensing cover comprising:

a main portion sized to fit within the perimeter of the cover-receiving opening;

a skirt portion which is secured to said main portion and which extends generally parallel to the upstanding drum wall;

a skirt portion extension which is secured to said skirt portion and which forms a cavity for receiving the rolled-in lip of the first fiberboard drum; and

a dispensing cover seal formed of a flexible material, said seal being secured to said main portion, said seal having an outer perimetric seal edge which sealingly abuts the continuous upstanding drum wall when said dispensing cover is inserted in the first fiberboard drum, said seal being positioned to impede retention, by the rolled-in lip, of product contained in the first fiberboard drum.

12. A dispensing cover as defined in claim 11, wherein:

said main portion has a bottom face; and

said dispensing cover seal is a generally planar sheet having an upper surface secured to said bottom face of said main portion.

13. A dispensing cover as defined in claim 12, wherein:

the continuous upstanding drum wall forms a generally rectangular tube with rounded corners;

said dispensing cover seal is generally rectangular with rounded corners; and

said dispensing cover seal is formed with angled slits in said rounded corners to aid in flexible engagement of said dispensing cover seal with the first fiberboard drum.

14. A dispensing cover as defined in claim 11, wherein said main portion is formed with a lid-receiving aperture, further comprising a lid which is configured to be resealably secured in said aperture.

15. A dispensing cover as defined in claim 11, for stacking use with a second fiberboard drum having a recessed floor retained by rolled-in edges, said dispensing cover further comprising:

a stack alignment lip extending upwardly from said main portion to engage the rolled-in edges of the second fiberboard drum when the second fiberboard drum is stacked on top of said dispensing cover.

16. A dispensing cover as defined in claim 15, wherein said main portion is formed with a lid-receiving aperture, further comprising a lid which is configured to be resealably secured in said aperture.

17. A dispensing cover for use with a first fiberboard drum and for stacking use with a second fiberboard drum, the first fiberboard drum having a continuous upstanding drum wall with a wall edge having a rolled-in lip, the wall edge forming a perimeter of a cover-receiving opening, the second drum having a recessed floor retained by rolled-in edges, said dispensing cover comprising:

a main portion sized to fit within the perimeter of the cover-receiving opening;

a skirt portion which is secured to said main portion and which extends generally parallel to the upstanding drum wall;

a skirt portion extension which is secured to said skirt portion and which forms a cavity for receiving the rolled-in lip of the first fiberboard drum;

at least one barb which is secured to said skirt portion and which extends outwardly therefrom, said barb having an angled surface which rides up and over the rolled-in lip of the first fiberboard drum as said dispensing cover is inserted in the first fiberboard drum, said barb having a generally straight surface which traps the rolled-in lip of the first fiberboard drum in said cavity of said skirt portion extension when said dispensing cover is fully inserted in the first fiberboard drum, said generally straight surface and said rolled-in lip of the first fiberboard drum interacting to permanently attach said dispensing cover to said first fiberboard drum; and

a stack alignment lip extending upwardly from said main portion to engage the rolled-in edges of the second fiberboard drum when the second fiberboard drum is stacked on top of said dispensing cover.
