Abstract
A bin comprising a vessel and a pivoting lid that can be moved between an open position and a closed position. The lid and the vessel are arranged in such a manner that the air leaving the vessel during closure of the lid and when the lid is close to its closed position is forced to turn at least twice, being forced to pass between substantially vertical surfaces belonging respectively to the lid and to the vessel, at least at the front of the lid, preferably at least at the front of the lid and on both sides therefore, and more preferably still all round the four edges of the lid, so as to encourage the creation of raised pressure inside the vessel, which raised pressure tends to brake the displacement of the lid towards its closed position.
