Expiration date device for cosmetic containers

Abstract

A system for providing an expiration month on cosmetic containers that store perishable make-up media including a container, a control, and a handle portion formed on the control. The handle portion has a greater outer diameter than an outer diameter of an exterior surface of the control wherein the greater outer diameter prevents the handle portion from entering the container, and a plurality of date-months formed on the exterior surface of the control in a sequential order in a first circumferential direction. The 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.

1 - 10 . (canceled) 
     
     
         11 . 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.   
     
     
         12 . The adjustable date control of  claim 11  wherein the handle portion is rotated in the second circumferential direction until a desired expiration date month is visible through the transparent portion of the container. 
     
     
         13 . The adjustable date control of  claim 11  wherein the control includes a flange formed on the exterior surface adjacent the first end of the chamber. 
     
     
         14 . The adjustable date control of  claim 11  wherein the container includes a raised surface formed on the interior surface adjacent the second end. 
     
     
         15 . The adjustable date control of  claim 14  wherein the flange and raised surface form an interlock between the container and the control when the control and container are rotationally disposed preventing a separation therebetween. 
     
     
         16 . 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 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.   
     
     
         17 . The cosmetic container of  claim 16  wherein the at least one male protuberance may be received in the anti-rotational recess and rotated out of the anti-rotational recess in a first direction toward the transitional step. 
     
     
         18 . The cosmetic container of  claim 16  wherein the anti-rotational recess prevents the at least one male protuberance from being rotated out in a second direction that is opposite the first direction thereby reducing the likelihood that a desired date-month will unknowingly be changed. 
     
     
         19 . The cosmetic container of  claim 16  wherein the anti-rotation wall has an angle of about 90 degrees. 
     
     
         20 . The cosmetic container of  claim 16  wherein the first predetermined distance is about equal to a diameter of the at least one male protuberance.
