Stopper (plug) in the context of "Barrel (storage)"

Psi, phi and tau were types of terracotta figurines made in Mycenaean Greece during the Late Helladic period. They were typically about 10 to 20 centimetres (3.9 to 7.9 in) high and are found in tombs, shrines and settlement areas. They fall into three distinct typologies, each named for the letter of the Greek alphabet that it resembles. The earliest such figures date to the Late Helladic II period (c. 1450 – c. 1400 BCE), and they continued to be made until the end of the Late Helladic III (c. 1050 BCE).

The figurines depict female forms, often wearing a polos headdress that may indicate a goddess or a worshipper. Some, known as the kourotrophos (lit. 'child-rearer') type, include a model of an infant. The function and original meaning of these figures is unclear, and may not have been the same to all Mycenaeans or at all stages in the object's use-life: some are found in clearly sacred or ritual contexts, such as sanctuaries or as offerings in tombs, while others are found in domestic contexts, household rubbish, or used for utilitarian functions such as stopping a vessel or as part of the temper used in mud-brick building.

A cruet (/ˈkruːɪt/), also called a caster, is a small flat-bottomed vessel with a narrow neck. Cruets often have a lip or spout and may also have a handle. Unlike a small carafe, a cruet has a stopper or lid. Cruets are normally made of glass, ceramic, stainless steel, or copper.

A bottle is a narrow-necked container made of an impermeable material (such as glass, plastic or aluminium) in various shapes and sizes that stores and transports liquids. Its mouth, at the bottling line, can be sealed with an internal stopper, an external bottle cap, a closure, or induction sealing.
