Yong K. Paek, an engineer with the Fairfax County government, has invented and obtained U.S. Patent No. 4,266,668 (16 claims) on a novel telescoping sliced bread dispenser. This interesting device can be manufactured from plastic, light metal, or wax-coated fiber board.
As nearly everyone knows, sliced bread and many other grocery products are sold in the United States in clear plastic wrappers such as vinyl, with one end secured by a wire or other wrap-around closure. The vinyl wrapper gives no support to the sliced bread and as the individual slices are removed from the package, the slices move about inside and are thus subject to being crushed and otherwise damaged. This invention promises to solve this problem.
The device, which consists of two telescoping, elongated, open-top, U-shaped trays, works as follows:
A loaf of sliced and wrapped bread is placed in the dispenser with the second part extended to the end of the loaf where the wrapper has a twister. The twister is removed from the plastic wrapper and the twisted end of the wrapper is inserted through a slot in the end of one of the trays (the one in which the loaf of bread is resting.)
As the slices are removed from the loaf, the twisted end is removed from the slot, unraveled, and the slices of bread are removed from the wrapper. The plastic wrapper is now again twisted and the tray holding the bread is pushed back into the first tray to compensate for the decreasing size of the loaf and the twisted end is again inserted into the slot.
Paek is negotiating with a Baltimore firm for the manufacture and marketing of the invention, which he estimates will retail at about $5.
