Lip product containers, and methods for manufacturing the same

1. A lip balm receptacle, comprising:

a curved, multi-layered upper portion, formed by a single two-step overmolding injection process using a cam-less inlay design mold, comprising:

i) an interior layer having an outer surface that identifies a flavor of a lip balm contained in the lip balm receptacle, the outer surface of the interior layer having an exposed portion, the exposed portion having a surface area; and

ii) an exterior layer bonded to the outer surface of the interior layer, the exterior layer having:

a) an outer surface with a different visual appearance than the outer surface of the interior layer, the outer surface of the exterior layer having a surface area;

b) a thickness of at least 0.25 mm and no more than 4 mm;

iii) a curved durable cutout design positioned about a debossed logo, the durable cutout design comprising at least one aperture through the exterior layer exposing a fixed portion of the outer surface of the interior layer; wherein:

1) the at least one aperture is located at a polar angle θ (theta) of between 5-60 degrees;

2) the ratio of the surface area of the outer surface of the exterior layer to the surface area of the exposed outer surface of the interior layer is at least 1:1 to no more than 97:3;

3) the ratio of the surface area of the outer surface of the exterior layer to the surface area of the exposed outer surface of the interior layer between the polar angle θ (theta) of 5-60 degrees is at least 90:10 to no more than 10:90;

4) the distance between any first at least one aperture and any second at least one aperture is equivalent to or greater than the thickness of the exterior layer; and

5) an aperture peripheral wall defined by the at least one aperture is substantially parallel to a longitudinal axis of the curved, multi-layered upper portion; and

iv) first threads; and

a lower portion having second threads, the lower portion connectable with the upper portion via interengagement of the first and second threads to fixedly close the lip balm receptacle.

2. The lip balm receptacle of claim 1 , wherein the exterior layer of the durable cutout design resists being torn from the interior layer for a lifetime of the lip balm receptacle.

3. The lip balm receptacle of claim 1 , wherein the exterior layer of the durable cutout design resists being removed from the interior layer for a usable lifetime of the lip balm receptacle.

4. The lip balm receptacle of claim 1 , wherein the durable cutout design exposes at least 5% and no more than 45%, of the surface area of the outer surface of the interior layer.

5. The lip balm receptacle of claim 1 , wherein the curved, multi-layered upper portion is exclusive of a flat or planar surface.

6. The lip balm receptacle of claim 1 , wherein a curvature of the interior layer is substantially parallel to the curvature of the exterior layer such that no portion of the curved interior layer mechanically interlocks within an aperture extending through the exterior layer.

7. The lip balm receptacle of claim 1 , wherein the aperture peripheral wall defined by the at least one aperture is beveled.

8. The lip balm receptacle of claim 1 , wherein the aperture peripheral wall defined by the at least one aperture is substantially perpendicular to the outer surface of the interior layer.

9. The lip balm receptacle of claim 1 , wherein the aperture peripheral wall defined by the at least one aperture is less than perpendicular to the outer of the interior layer.

10. The lip balm receptacle of claim 1 , wherein the exterior layer is in direct contact with the outer surface of the interior layer and exclusive of an adhesive layer between the exterior layer and the interior layer.

11. The lip balm receptacle of claim 1 , wherein a minimum thickness of the exterior layer is the narrowest dimension of the exterior layer.

12. The lip balm receptacle of claim 1 , wherein the thickness of the exterior layer is narrower than the smallest width of any of the at least one aperture through the exterior layer.

13. The lip balm receptacle of claim 1 , wherein a color of the exposed interior layer is a sole visual indicia of the lip balm flavor when the lip balm receptacle is closed.

14. The lip balm receptacle of claim 1 , wherein the aperture peripheral wall defined by the at least one aperture is within, plus or minus 1-10 degrees, of parallel to the longitudinal axis of the curved, multi-layered upper portion.

15. The lip balm receptacle of claim 1 , wherein the interior layer does not intersect an outer surface of a convex hull of the exterior layer of the lip balm receptacle.
