Square Clip Top Jars

At Wares of Knutsford we’re very proud of the size and variety of our range of jars and bottles, but we admit that so much choice can be bewildering, which is why we like to give you jar advice regularly.

Why use square clip top jars?

The majority of jars come in a round shape, but here today we want to extol the virtues of the square jar. It can be used for the same pickling, preserving and storage purposes as round jars but could, we argue be a more efficient use of space.

Square jars have one major advantage over round jars, which is that they use the space in corners which is wasted by round jars. If you are storing jars in a cupboard, square shapes will fill in where round jars leave gaps, making far better use of the available space.

Square jars can also be turned on their sides and stacked without slipping and falling the way round jar tend to.

Clip top jars over screw tops

Both clip and screw top jars are designed to seal efficiently to keep the contents fresh. In the case of preserves, they prevent bacteria from entering and spoiling the food and in the case of dried good they prevent air from staling the goods. As long as you can create a good seal, in theory both closures are as efficient as the other.

However clip tops are arguably easier to use than screw tops – it can be difficult to manoeuvre around a screw top if you only have one hand free, for example. While screw tops should be replaced every time you re-use a jar, clip top lids are more robust and can stand up to more intensive use. The only part that needs replacing is the red rubber sealing ring if it should degrade.
