Abstract: A push-up bra has an envelope between the front panel and the rear panel of the bra cups, that receives a flexible pouch containing a mixture of water and a hygroscopic agent such as 70% glycerine--30% water. The hygroscopic agent will draw moisture into the envelope preventing the volume of liquid from decreasing.

Abstract: A bar code printing device including a base frame, a cover turned about a pivot in the base frame, torsional springs mounted around the pivot to force the cover outwards from the base frame, gear wheel and sector gear assemblies mounted between the base frame and the cover to buffer the spring force of the torsional springs, a sticker reel mounted in the base frame and turned by a step motor to let off a sticker for printing, a ribbon reel mount fastened to the cover on the outside, a ribbon reel mounted on the ribbon reel mount and turned by a DC motor through a reducing gear to turn a ribbon over the sticker, the ribbon reel having a tension spring adapted for adjusting the diameter of the ribbon reel subject to the size of the ribbon to be used, and a control circuit for controlling the operation of the DC motor and the step motor.
