Abstract
A device for coupling two containers comprises a pair of connecting sleeves, each having closing flaps that can be moved from a closed position to an open position by a part-turn actuator, with the outer surfaces of each closing flap facing away from the container lying flush with the outer surface of the relevant connecting sleeve in the closed position and the closing flaps are each seated in an essentially circular seal. To prevent the accidental opening of the closing flaps, each of the connecting sleeves is provided with a radially-movable pin in the wall adjacent the seal, which pin can be pushed radially inward to produce a bulge in the seal which will hold the respective closing flap in its closed position and which pin can be radially moved outward to release the flap.
Claims15
In a device for coupling two containers having terminal connecting branches having an essentially circular cross section, said device including a pair of connecting sleeves having a circular cross section with one end being connectable to the connecting branches, each of said sleeves, at an outer end, having a circular seal and a pair of half-shell bearings lying diametrically opposite each other with each half-shell bearing having a semi-circular cross section, a closing flap having a substantially flat planar outer surface with a pair of half-axles having a semi-circular cross section extending diametrically opposite thereof, said closing flap being mounted for rotation with the half-axles disposed in the half-shell bearings and movable between a closed position with the flat surface of the flap and half-axles being flush with an end surface of the connecting sleeve and the flap seated in the circular seal to an open position extending approximately 90.degree. from the closed position, said flaps having their exposed surfaces engaging each other to form a full axle as the end surfaces of the two connecting sleeves are brought together, and a part-turn actuator engaging one of the flaps to rotate the flap between the open and closed position while the other flap is entrained to move therewith, the improvement comprising at least one radially-movable pin being provided in a wall of each of the connecting sleeves at the height of the circular seal, said pin being pushed radially inward producing a bulge in the circular seal for holding the respective closing flap in the closed position.
