Abstract

A lip application device, such as a lipstick, may have four peripheral portions in its cross section. The cross section may have a center through which a radial axis extends in parallel to the cross section, dividing the cross section into left and right sides. A first portion may form a first arc centered at the radial axis and having an outward radial direction stemming from the center. A second portion may form a second arc centered at the radial axis and having an outward radial direction stemming from the center, the second arc being opposite to the first arc and being longer than the first arc. A third portion and a fourth portion may be substantially straight lines, one connecting the ends points of the two arcs in the left side and other connecting the end points of the two arcs in the right side.

First claim

It is claimed:

1. A lipstick container, comprising:
a container body extending along a longitudinal axis and comprising a first end having an upper portion and a lower portion, a second end, and a cross section perpendicular to the longitudinal axis, the cross section comprising:
a center through which an axis extends in parallel to the cross section, the axis dividing the cross section into a left side and a right side;
a first peripheral portion intersecting the axis at an upper portion of the cross section; and
a second peripheral portion intersecting the axis at a lower portion of the cross section,

wherein a distance extending longitudinally from the upper portion of the first end of the container body to the second end of the container body is different than a distance extending longitudinally from the lower portion of the first end of the container body to the second end of the container body,
wherein the second peripheral portion is longer than the first peripheral portion, and the first peripheral portion comprises a first arc that is centered at the axis and extends away from the second peripheral portion,
wherein the second peripheral portion comprises a second arc that is centered at the axis and extends away from the first peripheral portion, and
wherein a cord length of the second arc is greater than as a chord length of the first arc.

2. The lipstick container of claim 1 , wherein the second peripheral portion is an arc so that the first peripheral portion and the second peripheral portion form a water drop shape with a pointed upper portion at the axis.

3. The lipstick container of claim 1 , wherein the chord length of the second arc is at least twice as long as the cord length of the first arc.

4. The lipstick container of claim 1 , wherein the ratio of the chord length of the second arc to the cord length of the first arc is 14 to 5.

5. The lipstick container of claim 1 , wherein the first end of the container body is angled relative to the cross section.

6. The lipstick container of claim 1 , wherein the distance extending longitudinally from the upper portion of the first end of the container body to the second end of the container body is greater than the distance extending longitudinally from the lower portion of the first end of the container body to the second end of the container body.

7. The lipstick container of claim 1 , wherein the cross section further comprises:
a third peripheral portion that forms a first substantially straight line connecting a first end point of the first peripheral portion and a first end point of the second peripheral portion in the left side of the cross section; and
a fourth peripheral portion that forms a second substantially straight line connecting a second end point of the first peripheral portion and a second end point of the second peripheral portion in the right side of the cross section.

8. The lipstick container of claim 1 , further comprising a lipstick that is telescopically attached to the container body and comprises an application end and a base end, wherein the first end of the container body is an application end that corresponds to the application end of the lipstick, and the second end of the container body is a base end that corresponds to the base end of the lipstick.

9. The lipstick container of claim 1 , further comprising a cover that is removably attached to the container body, the cover comprising a transparent window for indicating a color of a lipstick that is housed by the lipstick container.

10. The lipstick container of claim 1 , further comprising a base and a lipstick holder, wherein the lipstick holder is rotatably attached to the base.

11. A lipstick, comprising:
a container extending along a longitudinal axis; and
a lipstick body positioned within the container, extending along the longitudinal axis, and comprising a first end having an upper portion and a lower portion, a second end, and a cross section perpendicular to the longitudinal axis, the cross section comprising:
a center through which an axis extends in parallel to the cross section, the axis dividing the cross section into a left side and a right side;
a first peripheral portion intersecting the axis at an upper portion of the cross section; and
a second peripheral portion intersecting the axis at a lower portion of the cross section,

wherein a distance extending longitudinally from the upper portion of the first end of the lipstick body to the second end of the lipstick body is different than a distance extending longitudinally from the lower portion of the first end of the lipstick body to the second end of the lipstick body,
wherein the second peripheral portion is longer than the first peripheral portion, and the first peripheral portion comprises a first arc that is centered at the axis and extends away from the second peripheral portion,
wherein the second peripheral portion comprises a second arc that is centered at the axis and extends away from the first peripheral portion, and
wherein a cord length of the second arc is greater than as a chord length of the first arc.

12. The lipstick of claim 11 , wherein the second peripheral portion is an arc so that the first peripheral portion and the second peripheral portion form a water drop shape with a pointed upper portion at the axis.

13. The lipstick of claim 11 , wherein the chord length of the second arc is at least twice as long as the cord length of the first arc.

14. The lipstick of claim 11 , wherein the ratio of the chord length of the second arc to the cord length of the first arc is 14 to 5.

15. The lipstick of claim 11 , wherein the first end of the lipstick body is an application end and the second end of the lipstick body is a base end.

16. The lipstick of claim 11 , wherein the distance extending longitudinally from the upper portion of the first end of the lipstick body to the second end of the lipstick body is greater than the distance extending longitudinally from the lower portion of the first end of the lipstick body to the second end of the lipstick body.

17. The lipstick of claim 11 , wherein the cross section further comprises:
a third peripheral portion that forms a first substantially straight line connecting a first end point of the first peripheral portion and a first end point of the second peripheral portion in the left side of the cross section; and
a fourth peripheral portion that forms a second substantially straight line connecting a second end point of the first peripheral portion and a second end point of the second peripheral portion in the right side of the cross section.

18. A lipstick container, comprising:
a container body extending along a longitudinal axis and comprising a cross section perpendicular to the longitudinal axis,
wherein the cross section of the container body has a first curved peripheral portion on a right side thereof and a second curved peripheral portion on a left side thereof opposite to the right side,
wherein the second curved peripheral portion is longer than the first peripheral portion, and the first peripheral portion comprises a first arc that is centered at the axis and extends away from the second peripheral portion,
wherein the second curved peripheral portion comprises a second arc that is centered at the axis and extends away from the first peripheral portion, and
wherein a cord length of the second arc is greater than as a chord length of the first arc.

19. The lipstick container of claim 18 , wherein the container body further com
