Sales executive Matt Gough said: “There are companies out there that produce plastic ring pull tubes, but they require complex machinery to package the products and seal the tube.

“With our specific design it is the only one in the market, as far as we know, that you can package yourself. No special machinery is required.

“With our ring-pull tube, the customer is provided with a tube [cardboard or plastic] with a ring pull lid already seamed on. All they need to do is insert the contents and put the base plug in.

“As the base plug is well-fitted clip-in plug, it is very difficult to take once inserted.”

‘Wider market’

Gough also said that the new product was self-assembly, which made it open to a “much wider market”.
