A Japanese drinks producer caught the eyes of show visitors with its marble-stopper lemonade bottles, a concept it has been campaigning to revive.
Kimura Drink's Ramune lemonade is popular in Japan because it is sealed with a marble stuck inside the neck of the glass bottle so it doesn't need a cork or bottletop.
The pressure of the fizzy drink keeps the marble held firmly in place until the consumer wants a drink.
A spokeswoman for Kimura said the drink had proved popular with children in Japan. The company is looking for a UK distributor for Ramune, as well as other products from its soft drinks portfolio, which includes a bottled water range.
