The present invention relates to a single facer, which comprises a humidifying and heating unit placed on the upstream side of an air pressurization corrugating mechanism for humidifying and heating a corrugating medium and a feed mechanism for supplying the corrugating medium, processed by the humidifying and heating unit, to the air pressurization corrugating mechanism at a given speed. The corrugating medium is supplied at the given speed after the humidification and heating process for the corrugating medium, so that an air pressure to be taken at the corrugation is reducible and a predetermined flute configuration is maintainable. In addition, the spring back of the corrugating medium hardly occurs, which makes it possible to manufacture a corrugated fiberboard sheet with a high shock absorbing ability.

The Beverage Dispensing Box for Office and Kitchen Counters is intended to hold a flexible disposable beverage bag filled with a potable liquid and dispense that liquid under pressure when the spigot is opened. The Beverage Dispensing Box is unique in that it employs the law of gravity. Through the use of a sloped container floor and a weighted pressure plate, a natural force (non-mechanical or electrical) is applied to the flexible disposable beverage bag, thus causing the potable liquid to flow from the bag under pressure at a greater gallon per minute (GPM) rate than that of a typical un-pressurized flexible disposable beverage bag—commonly found in corrugated cardboard boxes such as the Wine-in-a-Box container; and at a greater GPM rate than that of a typical 2.5 or 5 gallon bottled water dispensing apparatus. The Beverage Dispensing Box is designed to sit on office, kitchen or other countertops where no electricity is required for use. The Beverage Dispensing Box is a durable reusable container that will positively impact the environment because it will be manufactured from recycled plastic and metals; and will displace the need for disposable plastic bottles, such as bottled water.
