Hi guys! What do you call the kind of chrome lock of the glass jar?

Thanks very much!

I can't think of a specific name for that type of jar or that type of locking mechanism. I'd probably just use a brief description..."one of those jars with the clamp-down lids." I see several references, online, to "Fido jars". Fido was a brand name of food storage jars, of this type, made by the glass company Bormilio Rocco. Fido might be evolving into a genericized term but it's probably too early to expect that everyone will know what you mean.

We would call them kilner jars. But what the mechanism is called is anyone's guess.
(A man called Kilner invented them in Yorkshire)

I would call the clamp a spring-clip {retainer / fastener}.

Jars for home canning are usually referred to as Kilner jars in the UK (as Bob mentioned), and Mason jars in the USA.

I have also found them described online as Fido jars (which Trolley mentioned) and wire bale jars. Both of these two names are new to me, and neither of them scores very many Google hits, so my guess is that Kilner jar and Mason jar are the most usual terms.

The jars are designed for preserving food. This is done by heating the contents with the lid held in place. During heating pressure builds up in the jar and steam will escape. There are two main methods of holding the lid on during the heating, these are a screw down clip or , as in this case, a spring clip.When the jar cools a partial vacuum is formed and the lid is held on by the vacuum. At this point the spring clip can be undone, or the screw clamp can be removed.
In all cases (that I know of) the bottle and fastening is known by the brand of the glass bottle manufacturers. These were used as an alternative to tin cans. The process is still often referred to as canning although some people will say bottling.


Clip top or Spring clips are now often used as decorative closures on jars. Clip tops are also used on pressurised bottles such as beer bottles.
