South African inventor Barry Geer has filed a patent for a bag-in-box packaging system for dispensing liquids. Featured in ThePackHub’s Patent Zone, the concept builds on the established combination of a flexible liquid-containing bag and a rigid outer box.
Bag-in-box formats are commonly used for beverages including wine and juice, as well as liquid food products. The flexible bag typically incorporates a tap or spout for dispensing, while the outer box provides protection and makes the format easier to store and handle.
Geer’s patent covers developments to this established packaging format.
Combining flexible and rigid packaging
The bag-in-box format brings together two distinct packaging components. A flexible plastic bag holds the liquid product, while a rigid cardboard box forms the external structure.
The bag is designed to collapse progressively as its contents are dispensed. This reduces the amount of air entering the pack during use, helping to maintain the contents after opening. The dispensing component also allows the product to be served without removing the inner bag from its outer packaging.
The rigid box performs a different role, protecting the flexible container and providing a more structured format for storage and handling. Its regular shape also lends itself to stacking, while the integrated dispensing arrangement provides consumers with a convenient means of accessing the contents.
Addressing storage, dispensing and transport
Bag-in-box packaging is used where brands require a relatively lightweight alternative to glass bottles for suitable liquid products. The format can also offer practical advantages in transport and storage because of the shape of the outer box.
For consumers, the built-in dispensing system is central to the format’s functionality, allowing repeated dispensing while the flexible inner bag contracts as product is removed.
Geer’s patent indicates continued development around this established combination of a flexible container, rigid outer structure and dispensing mechanism.
