Party balls are spherical containers that are used instead of traditional beer kegs. Introduced during the 1980’s, the party ball usually has a capacity of five gallons, which is one third of the usual capacity for a keg. Designed to be a disposable device, the first party ball types were equipped with a tap to allow easy distribution of the beer within the device.

The party ball is usually constructed of lightweight but durable plastic. Because of the size of the device, a party ball can normally be transported with greater ease than the standard keg. This makes it possible for keggers to load a party ball into the back seat or trunk and transport the ball to beaches, campsites, or parties in private residences with relative ease. Because the party ball is made of disposable materials, the device can be placed into the trash once it is empty.

To cool the beer contained in a party ball, some manufacturers include a specially designed box to hold the device. The interior of the box is lined with plastic, makes it possible to surround the party ball with crushed ice. At the same time, the plastic prevents the box from weakening due to exposure to melted ice.

While the party ball was initially meant to be a disposable container for beer, it was not long until several manufacturers began to offer refillable party balls. While the simple spherical design with the addition of a tap is still the norm, some manufactures today include an electrical base that allows the liquid within the bowl to be cooled without the need for ice.

Collecting party ball issues from years past has become a popular craze. Various online auctions feature bids on party ball designs issued by one beer company or another over the years. In addition, some online retailers also offer older party balls, less the beer, for sale. While the party ball was once considered ideal for use by college students, many adults today choose to use a party ball for get togethers in the home.
