The innovation, aimed at the beverage processing industry, has been granted a patent and Spanish developer, David Guispe Gonzales, is seeking investment with a view to establishing a licensing agreement for the manufacture of the new type of aluminium can. According to the patent description, the can has two separate compartments, with each one sized to contain contents that correspond approximately to a single consumption. Two easy-opening ring pulls on the can's lid enable consumption of the drinks on separate occasions or together to form a mixed drink, said the developer. Guispe Gonzales claims this dual-drink container will provide consumers that want to mix drinks such as beer and lemonade with a cost effective alternative to the more conventional method of purchasing two beverage cans or a can and bottle. The inventor said that valves connected to the opening device on each compartment prevent the involuntary spilling of the contents in either section when the can is inclined in the opposite direction. Resealable can Meanwhile, beverage can producer Ball Packaging Europe recently launched a resealable beverage can, which the company claims could change the face of the beverage can market. The Ball Resealable End is an aluminium can end into which a flat opening mechanism made of plastic is integrated. A simple rotating movement uncovers the opening, explained the company. Developed in association with Coca-Cola and Dutch firm Bound2B B.V., the new type of can end was launched on the French market in March with Coca-Cola's energy drink 'Burn'. Beverage cans are popular with drink manufacturers and consumers alike because they are light, easy to open, quick to cool, and non-breakable. They also keep their contents fresh, with the hermetic seal eliminating the need for a special tamper-guard. However, the one major drawback of traditional beverage cans is that they cannot be kept after initial opening as they are not resealable. Ball Packaging Europe claims to have solved this problem with its new end type, which makes it possible to reseal steel and aluminium cans after opening. The company claims that the new resealable end forms a complete barrier against light and gas, preserving the product's long shelf-life. A tamper-proof feature on the resealable end also allows the consumer to check that the seal has not been broken, said the company. Easy to stack and store As well as appealing to consumers, the company said its new can, which retains the classic shape of a beverage can, would also appeal to retailers as it remains easy to stack and store. For the same reason, it would also be easy to transport, it said. In addition, Ball Packaging Europe has limited the amount of plastic used for its new container so as not to affect the cans' recyclability.
