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 method for filling a lip balm mold comprising transferring a molten lip balm composition into the lip balm mold through an aperture in a partition in the lip balm mold to a fill level approaching the partition but not touching the partition;
wherein said lip balm mold comprises:
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.

2. The method for filling a lip balm mold of claim 1 , wherein the fill level provides a pocket of air between the partition and the molten lip balm composition.

3. The method for filling a lip balm mold of claim 2 , wherein the pocket of air is about 0.5 mm to about 7 mm thick.

4. The method for filling a lip balm mold of claim 3 , wherein the pocket of air is about 1 mm to about 5 mm thick.

5. The method for filling a lip balm mold of claim 4 , wherein the pocket of air is about 1.5 mm to about 4 mm thick.
