Abstract

A three to six sided lip balm applicator of the present invention comprises a cap, a liner, and a base, having engagement assemblies for engaging the cap to the liner the liner to the base, and a base from one lip balm applicator to an equivalent base from another lip balm applicator to form a lip balm container. The base comprises a partition with stabilizers which emerge from the partition and extend radially toward and overhang an aperture in the partition. The lip balm applicator may contain a domed lip balm, filled directly into the lip balm applicator or components thereof as a mold for manufacturing the domed lip balm, filled to a fill level approaching the partition top but not touching the partition top.

First claim

We claim:

1. A lip balm dispenser comprising:
a liner comprising a domed upper liner section, a lower liner section with a liner perimeter, a liner exterior, a liner interior having a lower liner interior and an upper liner interior, and a first liner engagement assembly on the lower liner interior; wherein the liner perimeter optionally has a cap engagement assembly; and
a base comprising an upper base section having a base top edge, a lower base section, a partition dividing the upper base section and the lower base section and extending to a base perimeter, the partition having a partition bottom and a partition top, with the partition top having an outer partition top section and an inner partition top section, an aperture in the partition, an upper base section exterior wall comprising a second liner engagement assembly which aligns with the first liner engagement assembly and engages the lower liner interior with the upper base section exterior wall, an upper base section interior wall, a plurality of stabilizers arising from a first area adjacent to the upper base section interior wall on the inner partition top section, rising to a level at or near horizontal with the base top edge and extending radially inward to a second area overhanging the aperture, a gap between each stabilizer and the upper base section interior wall, and a base engagement assembly on the lower base section which provides releasable engagement of a lower base section on the lip balm dispenser with a lower base section on a lip balm applicator or second lip balm dispenser; wherein the base has three to six sides.

2. The lip balm dispenser of claim 1 , wherein the plurality of stabilizers is six stabilizers.

3. The lip balm dispenser of claim 1 , wherein the plurality of stabilizers comprises three vertical blades and three vertical blades with horizontal fins, configured alternatingly.

4. The lip balm dispenser of claim 3 , wherein the lip balm applicator has four equivalent sides.

5. The lip balm dispenser of claim 4 , wherein the sides are longitudinally curved outward such that the cap bottom perimeter is larger than the cap top perimeter.

6. The lip balm dispenser of claim 5 , wherein the cap top is indented from the cap flat edge.

7. The lip balm dispenser of claim 6 , wherein the base engagement assembly is a snap-fit comprising at least one tab having at least one bump and at least one tab having at least one hole.

8. The lip balm dispenser of claim 7 , wherein the snap-fit consists of two first tabs having at least one bump each and two second tabs having at least one hole each.

9. The lip balm dispenser of claim 8 , wherein the two first tabs have two bumps each, and wherein the two second tabs have two holes each and wherein the two first tabs and the two second tabs are configured alternatingly on the base.

10. The lip balm dispenser of claim 9 , wherein the upper base section exterior wall and the lower liner interior are circular; wherein the first liner engagement assembly and the second liner engagement assembly are complementary inclined planes which form a screw-fit; wherein the upper base section exterior wall comprises at least one ramp, at least one hollow, at least one chock; wherein the lower liner interior comprises at least one pin; and wherein the at least one pin aligns with the at least one hollow and the at least one chock stops the liner from rotating.

11. The lip balm dispenser of claim 10 , wherein the lip balm applicator further comprises a lip balm.

12. The lip balm dispenser of claim 11 , wherein the lip balm comprises at least one ingredient selected from the group consisting of a moisturizing agent, flavorant, sweetener, colorant, medicament, sunscreen, taste-masking agent, sensate, antioxidant, preservative, and combinations thereof.

13. The lip balm dispenser of claim 11 , wherein the lip balm is positionally stabilized by stabilizers.

14. A lip balm mold comprising:
a liner comprising a domed upper liner section, a lower liner section with a liner perimeter, a liner exterior, a liner interior having a lower liner interior and an upper liner interior, and a first liner engagement assembly on the lower liner interior; wherein the liner perimeter optionally has a cap engagement assembly; and
a base comprising an upper base section having a base top edge, a lower base section, a partition dividing the upper base section and the lower base section and extending to a base perimeter, the partition having a partition bottom and a partition top, with the partition top having an outer partition top section and an inner partition top section, an aperture in the partition, an upper base section exterior wall comprising a second liner engagement assembly which aligns with the first liner engagement assembly and engages the lower liner interior with the upper base section exterior wall, an upper base section interior wall, a plurality of stabilizers arising from a first area adjacent to the upper base section interior wall on the inner partition top section, rising to a level at or near horizontal with the base top edge and extending radially inward to a second area overhanging the aperture, a gap between each stabilizer and the upper base section interior wall, and a base engagement assembly on the lower base section which provides releasable engagement of a lower base section on a first lip balm mold with a lower base section on a lip balm applicator, a lip balm dispenser, or a second lip balm mold, wherein the base has three to six sides;
wherein the liner and the base are engaged through the first liner engagement assembly and the second liner engagement assembly, and
the engaged liner and base are inverted such that the partition bottom is facing upward.
