The Problem Solved by the Technology

Air pollution, flies, insects and dust are a constant problem for people dining and drinking in the open air or in hotels, restaurants, bars and diners with outdoor dining and drinking facilities.

Competitive Advantage

Glasscovers for wineglasses are less expensive to produce than competitor glasscovers and they can be supplied in a one-size 100 mm diameter that will cover a wide range of drinking glass sizes normally used in hotels, bars and restaurants. Competitor glass covers are glass size specific i.e. a 55 mm diameter glass must use a 55 mm glass cover. Hotels, bars and restaurants would require 35 competitor glasscover cap sizes in stock (and a lot of storage space) to cover the same range of glasses covered by Glasscovers for wineglasses. Glasscovers for wineglasses require very little bar storage space and are easy to use and serve with drinks either as Glasscovers or drinks coasters.
