Abstract

A container has a side wall thickness profile sufficient for withstanding loads such as a top load, a package including the container and a lid, and methods and systems related to the container, are disclosed.

First claim

The invention claimed is:

1. A wipes dispensing package, comprising
a wipes dispensing container defining a product storage region, the container comprising: a tapered side wall, a bottom coupled to a lower end of the side wall, a brim located at a top end of the container and defining an opening into the product storage region, and a shoulder disposed between the brim and the side wall and including a shoulder bottom coupled to an upper end of the side wall and a shoulder side wall coupled to an upper end of the shoulder bottom and the brim; and
a wipes dispensing lid coupled to the brim of the container to close the opening, the wipes dispensing lid including an attachment portion for coupling to the wipes dispensing container, a covering portion movable between an open position and a closed position relative to the attachment portion, and a dispensing portion coupled to the attachment portion and extending in an inward direction to overly the opening formed by the brim and configured to hold a wipe to facilitate dispensing of the wipe from the product storage region,
wherein the brim extends in an outward direction away from the side wall and the shoulder and has an outer diameter larger than a diameter of the bottom, a diameter of the side wall, and a diameter of the shoulder,
wherein the bottom includes a bottom flat area coupled to the lower end of the side wall and a bottom raised area coupled to an inner end of the bottom flat area and located entirely above the bottom flat area in a vertical direction.

2. The wipes dispensing package of claim 1 , wherein the side wall has an upper area, a lower area, and a central area disposed between the upper area and the lower area in a vertical direction;
wherein the upper area has a thickness in the range of about 0.010 inches to about 0.030 inches, the central area has a thickness in the range of about 0.010 inches to about 0.030 inches, and the lower area has a thickness in the range of about 0.010 inches to about 0.030 inches;
wherein the container has a weight of about 35 grams; and
wherein the container is configured to withstand a top load of at least about 120 lbs.

3. The wipes dispensing package of claim 1 , wherein the bottom raised area is disposed radially inside the bottom flat area.

4. The wipes dispensing package of claim 3 , wherein the bottom flat area has a thickness in the range of about 0.010 inches to about 0.030 inches and the bottom raised area has a thickness greater than the thickness of the bottom flat area in the range of about 0.020 inches to about 0.060 inches.

5. The wipes dispensing package of claim 1 , wherein the shoulder has a thickness in the range of about 0.010 inches to about 0.030 inches.

6. The wipes dispensing package of claim 1 , wherein the side wall is substantially frusto-conical and tapered away from a central axis of the container at a first angle and the shoulder includes a shoulder side wall tapered toward the central axis at a second angle such that the container is configured to allow stacking of one container on another container.

7. The wipes dispensing package of claim 6 , wherein the side wall is tapered at an angle of about 2.80 degrees relative to a central axis.

8. The wipes dispensing package of claim 1 , wherein the container is configured to withstand a top load of at least about 150 lbs.

9. The wipes dispensing package of claim 1 , wherein the container is formed of polypropylene.

10. The wipes dispensing package of claim 1 , wherein the covering portion of the wipes dispensing lid is movable about a hinge between the open position and the closed position relative to the wipes dispensing container.

11. The wipes dispensing package of claim 10 , wherein the wipes dispensing lid includes a dispensing portion having an entry slot configured to receive a wipe and a holding portion configured to hold the wipe.

12. The wipes dispensing package of claim 1 , wherein the attachment portion of the wipes-dispensing lid has an outer diameter greater than the outer diameter of the brim.

13. The wipes dispensing package of claim 1 , wherein the side wall of the wipes dispensing container has a thickness in the range of about 0.010 inches to about 0.030 inches;
wherein the wipes dispensing container has a weight of less than or equal to 37 grams; and
wherein the wipes dispensing container is configured to withstand a top load of at least about 100 lbs.

14. The wipes dispensing package of claim 1 , wherein the side wall of the wipes dispensing container has a thickness in the range of about 0.010 inches to about 0.030 inches, the bottom flat area has a thickness that is about equal to the thickness of the side wall, and the bottom raised area has a greater thickness than the thickness of the bottom flat area.

15. A method of providing the wipes dispensing package of claim 1 , the method comprising the steps of:
providing a sheet of material having a thickness of about 0.160 inches to about 0.200 inches;
thermoforming the sheet of material into the wipes dispensing container having a depth in the range of about 6″ to about 8″, wherein the side wall is a tapered side wall having a first angle such that the side wall is wider at the top than at the bottom, and with an angled shoulder having a second angle such that the shoulder is narrower at the top than at the bottom;
combining a plurality of containers including the wipes dispensing container into a container stack;
providing a plurality of container stacks into a rectangular array; and
providing the rectangular array in a shipping container.

16. The method of claim 15 , further comprising the step of stacking a plurality of shipping containers on a pallet.

17. The method of claim 16 , further comprising the step of transporting the pallet from a first location to a second location.

18. A shipping system for shipping the wipes dispensing package of claim 1 included in a plurality of stackable containers, comprising:
a pallet having a plurality of layers, each layer including a plurality of shipping containers;
each shipping container of the plurality of shipping containers including a rectangular array of container stacks;
each container stack including at least two containers stacked together;
wherein each container stack includes at least one upper container having a height that is inserted at least 50 percent into a lower container;
wherein each container has a tapered side wall that is wider at the top than at the bottom;
wherein each container includes a shoulder that is tapered radially inwardly as it extends from a shoulder bottom to a brim to provide a stacking shoulder having a shoulder height that is not inserted into a lower container when in the container stack;
wherein each container has a weight of 37 grams or less; and
wherein each container has a top load rating of at least 100 lbs.
