Reusable jam jar

A jar is a rigid, approximately cylindrical container with a wide mouth or opening. Jars are typically made of glass, ceramic, or plastic. They are used for foods, cosmetics, medications, and chemicals that are relatively thick or viscous. They are also used for items too large to be removed from a narrow neck bottle.

A closure applied to the mouth of a jar can be a screw cap, cork stopper, or other suitable means.

Jars are often recycled according to the SPI recycling code for the material. Some regions have a legally mandated deposit which is refunded after returning the container to the retailer. Some recyclers have concerns about possible residue in the jar from the viscous contents.
