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.
Claims65
A bin comprising a vessel and a pivoting lid that can be moved between an open position and a closed position, the vessel having at least one collar, wherein the lid and the vessel are arranged in such a manner that 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 thrice, being forced to pass through an air passage defined by a gap between substantially vertical surfaces belonging respectively to the lid and to the vessel, at least at a front 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 as the lid travels towards its closed position, wherein all of said substantially vertical surfaces are spaced apart from each other when the lid is in its closed position, wherein at least one substantially vertical surface belonging to the lid has a free end that rests only on said collar when the lid is in its closed position and is spaced apart from said collar when the lid is in its open position, and wherein the lid is deprived of perforations.
A bin comprising:
- a vessel having at least one collar;
- a pivoting lid that can be moved between an open position and a closed position;
- two first substantially vertical walls on one of the lid and the vessel, the two first substantially vertical walls extending at least at a front of the bin;
- and
- at least one second substantially vertical wall on the other one of the lid and the vessel which is configured to penetrate between the two first substantially vertical walls when the lid is close to its closed position, such that said first substantially vertical walls overlap the at least one second substantially vertical wall, at least partially,
- wherein said substantially vertical walls do not contact each other when the lid is in its closed position, and
- wherein at least one substantially vertical wall belonging to the lid has a free end that rests only on said collar when the lid is in its closed position and is spaced apart from said collar when the lid is in its open position.
A bin comprising:
- a vessel having at least one collar;
- a pivoting lid that can be moved between an open position and a closed position;
- two first substantially vertical walls on one of the lid and the vessel, the two first substantially vertical walls extending at least at a front of the bin;
- and
- at least one second substantially vertical wall on the other one of the lid and the vessel which is configured to penetrate between the two first substantially vertical walls when the lid is close to its closed position,
- wherein said substantially vertical walls do not contact each other when the lid is in its closed position,
- wherein at least one substantially vertical wall belonging to the lid has a free end that rests only on said collar when the lid is in its closed position and is spaced apart from said collar when the lid is in its open position, and wherein the lid is deprived of perforations.
