Cafe/bar equipment - what was it ??

[Paul-427]

On a recent trip to Sardinia, I saw a staff member from beach bar taking about 6 large clear plastic tubes to the bins. Their use has puzzled me since and my wife thinks I'm daft for wanting to find out more as I was unable to ask about them at the time.

They are rigid clear plastic about 800mm long and 300mm diameter with both ends domed and a small opening about 50mm, in one end. Inside was a deflated silver sack/liner attached to the opening.

In another town, I saw some that had been converted with the sides cut out and decorated into hanging baskets ( see photo)

Any ideas as Google and AI were unable to help ?

Some sort of drink dispenser refill cartridge I imagine.

As above, a post mix syrup cartridge of some kind maybe

Chat GPT agrees.

Based on the description provided, the object is likely a type of bag-in-box container for drink syrup, known as a postmix cartridge. These cartridges are used in bars with soda fountains to dispense concentrated syrups that are then mixed with carbonated water to create soft drinks. The specific dimensions and the presence of a deflated silver liner attached to an opening are consistent with this type of commercial packaging, which is designed for easy dispensing and to protect the syrup from oxidation. The bag-in-box system uses a flexible liner that collapses as the syrup is used, which helps to extend the product's shelf life.

This was all the info I could find/ deduce but no image searches showed the same thing. I guessed the use of rigid plastic suggested some form of pressure dispensing from the silver bag inside.
