Abstract
Abstract This invention pertains to an ice guard particularly adapted to be placed within a drinking glass to hold solid or semisolid material within the glass while the glass is tilted for drinking from said glass. The guard is preferably a plastic unit molded so as to incorporate and provide an integral tongue member connected to the guard body by a U-shaped portion. This U-shaped portion acts as a spring and moves the tongue into engagement with and retains the tongue in engagement with the interior of the glass. The installed guard is perforated and provides a screen which prevents the larger particles of ice and like material from passing from the glass while the fluid is permitted to pass by and around the screen and from the glass.
