A refillable packaging container for a roll-on material includes a body having a cup at its upper end, a spherical roller ball sitting within and retained by the cup, a refill container configured to contain a roll-on material, and a lid. A method of forming a packaging container includes inserting a refill container configured to contain a roll-on material into a body having a cup at its upper end, a first connection below the cup, and an opening at its lower end, wherein the cup retains a spherical roller ball and retaining the refill container with the body to form the packaging container.
1. A refillable packaging container for a roll-on material, comprising:
a body having a cup at its upper end, a first connection below the cup, and an opening at its lower end;
a spherical roller ball sitting within and retained by the cup;
a refill container configured to contain a roll-on material and that is inserted into the body at the lower end and is detachably retained within the body; and
a lid, that fastens onto the first connection,
wherein the body and refill container comprise a latching mechanism, the latching mechanism comprising latches extending from the lower end of the body that fit within grooves in the refill container,
wherein release of the latches from the grooves allows the body and refill container to be rotated with respect to one another.
2. The refillable packaging container of claim 1 , wherein the lower end of the body and a lower end of the detachable refill container are threadedly attached when the refill container is retained within the body.
3. The refillable packaging container of claim 1 , wherein the upper end of the body and upper end of the refill container threadedly attached when the refill container is retained within the body.
4. The refillable packaging container of claim 1 , wherein the body further comprises a detachable rear cap that is screwed to the lower end of the body, thereby fully encompassing the refill container.
5. The refillable packaging container of claim 4 , wherein the refill container is locked within the body and the rear cap.
6. The refillable packaging container of claim 1 , wherein the body and lid are each formed from at least one selected from the group consisting of polyethylene, polypropylene, acrylonitrile butadiene (ABS), polycarbonate (PC), polyamide (PA), and combinations thereof.
7. The refillable packaging container of claim 1 , wherein the refill container is formed from at least one selected from the group consisting of polyethylene, polypropylene, polyethylene terephthalate, and combinations thereof.
8. The refillable packaging container of claim 1 , wherein the spherical roller ball is formed from polyethylene or polypropylene.
9. The refillable packaging container of claim 6 , wherein the polyethylene is a high-density polyethylene.
10. The refillable packaging container of claim 1 , wherein the body, the spherical roller ball, the refill container, and the lid are formed from polypropylene.
11. The refillable packaging container of claim 1 , wherein the body, the spherical roller ball, the refill container, and the lid are formed from polyethylene.
12. The refillable packaging container of claim 1 , wherein the body comprises piercing elements.

retaining the refill container with the body to form the packaging container of claim 1 .
16. The method of claim 15 , further comprising replacing the refill container with a new refill container.
17. The method of claim 16 , wherein the new refill container has a different volume than the refill container.
18. The method of claim 15 , further comprising: refilling the refill container with the roll-on material prior to the inserting.
19. The method of claim 15 , further comprising forming the body by injection molding.
20. The method of claim 15 , further comprising forming the lid by injection molding or thermoforming.
