Expiration date device for cosmetic containers

A system for providing an expiration month on cosmetic containers that store perishable make-up media, comprising:

• a container having a circumferential wall that defines an opening into a cylinder at each of a first and a second end of the container, the cylinder is defined by an interior and an exterior surface wherein the interior and exterior surfaces define an aperture providing communication therebetween;
• a control having a circumferential wall that defines an opening into a first end of a chamber, wherein the chamber is defined by an interior surface of the circumferential wall that provides storage space for make-up media and wherein the circumferential wall of the control has a message portion formed on an exterior surface that is visible through the aperture wherein the message portion of the control is rotationally engaged in the opening of the first or second end of the container;
• a first handle portion formed on the control wherein the first handle portion has a greater outer diameter than an outer diameter of the message portion of the control wherein the greater outer diameter prevents the first handle portion from entering the cylinder;
• a second handle portion having a make-up media applicator member extending therefrom, wherein the applicator member is selectively operable to be received within the other opening of the first or second end of the container, wherein the second handle portion is spaced from and opposed to the first handle portion;
• and
• a plurality of date-months formed on the message portion of the control in a sequential order in a first circumferential direction wherein the first handle portion rotates the control in a second circumferential direction that is opposite the first circumferential direction thereby changing the date-months until the desired expiration date-month is visible in the aperture;
• and
• a first channel formed on the exterior surface of the message portion of the control extending therearound and a second channel formed in the interior surface of the cylinder extending therearound at a position that is along the same plane as the first channel when the control is engaged in the container wherein each of the channels receives a portion of an o-ring seal.

An adjustable date control for cosmetic containers housing perishable make-up media, comprising:

• a container having a circumferential wall that defines an opening into a cylinder having a first and a second end, the cylinder is defined by an interior surface wherein the circumferential wall includes a transparent portion visible through an exterior surface and the interior surface and wherein the transparent portion;
• a control engaged in the cylinder having a circumferential wall that defines an opening into a first end of a chamber that is defined by an interior surface of the circumferential wall and an exterior surface having a message portion that is visible through the transparent portion of the container wherein the message portion has each month of the year formed sequentially in a first circumferential direction around the message portion of the control;
• and
• a handle portion formed on the control adjacent a second end, the handle portion has an outer diameter that is greater than an outer diameter of the exterior surface of the circumferential wall wherein the handle portion moves the control in a second circumferential direction that is opposite the first circumferential direction.

A cosmetic container having an adjustable date control, comprising:

• a container having a circumferential wall that defines an opening into a cylinder at each of a first and a second end of the container, the cylinder is defined by an interior and an exterior surface wherein the interior and exterior surfaces define an aperture providing communication therebetween;
• a control rotationally engaged with the container, the control having a shape that conforms to the cylinder, the control having a (ADD 2 SPEC) solid cross-section, wherein an exterior surface of the control that is adjacent a first end of the control defines a message portion formed thereon that is visible in the aperture wherein at least one male protuberance is formed on the message portion of the control, the exterior surface of the control adjacent a second end of the control defines a handle portion that enables the control to be rotated;
• an anti-rotation recess formed in the circumferential wall of the container having a first and a second lateral wall formed perpendicular to a longitudinal centerline of the container and spaced apart a first predetermined distance wherein the anti-rotation recess includes an anti-rotation wall that joins the first and second lateral wall along the longitudinal axis and a transitional step that joins the first and second wall along the longitudinal axis and is spaced apart a second predetermined distance from the anti-rotation wall;
• and
• the circumferential wall having a maximum thickness at the transitional step and a minimum thickness where the first and second lateral walls join the anti-rotational wall.
