Jan. 29, 1957 R. ROSSETTI CLOSING DEVICE FOR TUBULAR DUCT Filed Jan. 12, l954 CLOSING DEVICE FOR TUBULAR DUCT Ren Rossetti, Geneva, Switzerland Application January 12, 1954, Serial No. %3,513 Claims priority, application Switzerland March 2, 1953 1 Claim. (Cl. 222-507) The present invention relates to a closing device adaptable, for instance, to a neck. This device difiers from the known devices by the fact that it comprises a carrier presenting a duct and intended to be aflixed onto the end of a duct, a cap rotatively mounted on the said carrier and provided with an opening and an oscillating valve element arranged inside the cap and actuated by the relative angular displacements between the cap and the carrer.

The attached drawing shows diagrammatically and by way of example a closing device.

Fg. 1 is a perspective view of the device, the cap being supposed to be transparent and the valve element being in open position.

Fig. 2 is a View of the device, the valve element being in closed position and certain parts of the cap being cut away, and

Fig. 3 is a View with cut away parts of the device.

Referring to the drawing in detail, the closing device comprises three main parts, namely: (a) a carrier 1 intended to be afiixed onto the neck of the container, such as deformable tubes for paste products; (b) a cap 6 rotatively mounted on the carrier 1 and having an upwardly facing semi-spherical portion; (c) and a ball mernber 11.

The carrier 1 has a semispherical portion threaded on the inside 16 for attachment to the neck of a deformable tube for paste products, and a semi-spherical cavty 17 facing upwardly, and an axal canal 5. The carrier 1 is provided with an upper flange engaging a groove in the cylindrical portionof the cap 6. A finger 13 projects outwardly from the concave portion 17 to engage a slot 14 in the lower portion of the ball 11. The ball 11 is provided with a diametrical canal 19 which in one position connects the canal of the carrier 1 With a centrally located opening of the semi-spherical portion 18 of the cap 6. The ball or sphere 11 is provided with a single trunnion 20 which engages a hearing 23 formed in the upper portion of the cap 6. Thus, when actuation of this cap takes place, the sphere 11 is driven in the angular displacement of said cap and the trunnion 20 slides on the edge 24 of the half-spherical cavity 17. The slot 14 is made along an equatorial circle of the sphere Situated in the diametrical plane passing by the trunnion 20 and which forms, with the axis of the canal 19, a 45 angle. This being so, during an angular displacement of 90 of the cap 6 in the direction of arrow a from the position represented on Fg. 1, the finger 13 traverses the whole length of the slot 14, which is now situated in the vertical plane passing by the canal 5, the opening 10 and the finger 13 (Fig. 2).

During a further angular displacement of 90" of the cap in the direction of arrow a, the finger 13 traverses the slot 14 in the opposite direction. After a total angu- States Parent O lar displacement of 180 of the cap, the sphere 11 has performed an oscillation of along the axis of the trunnion 20 and the canal 19, which connected the canal 5 with the opening 10, now forms a 90" angle with the axis of the canal 5 (Fig. 3) and the slot 14, which was Situated on the right of the vertical plane is now situated on the left of this plane.

Thus, in accordance with this enbodiment, the slot 14 is easy to machine, as it is Situated in a diametrical plane of the sphere, and moreover, its length is very small since the finger 13 traverses it twice, in opposite directions, in order to cause the opening or the closing of the device. This fact enables one to achieve very easily an absolutely fluid-fight device, owing to the very great distances separating the slot 14 from the canal 5 on the one hand, and from the opening 10 on the other hand.

It is clear that in another embodiment modification, the slot 14 could be made in one of the half-spherical cavity 17 or 18, the finger 13 being then fastened to the sphere 11. a

Tests carried out, either with metallic parts or with parts made of die-cast material, have enabled to ascertain that it is easy to achieve a perfect liquid-tightness, and that it is even possible to achieve gas-tightness by encrusting into the sphe'e 11, a tightening piece made of a flexible and elastic material which places itself in front of the opening 10 for the closed position of the device. This tightening piece is then kept applied against the edges of the opening 10 by the pressure of the gases acting, through the canal 5, on the sphere 11.

I claim: i

A closure device comprising a carrier, a cap rotatably mounted on the carrier, a spherical ball, said cap and said carrier cooperating to form a spherical housing extending partly into the carrier and partly into the cap for receiving said ball, said ball having a duct extending diametrically therethrough, said carrier and said cap having aligned openings, adapted to be connected by the duct in said ball, a trunnion extendng axially of the ball in a direction perpendicular to the duct, said trunnion engagng a recess located in the cap and adapted to move in a diametrical plane of the housing perpendicular to the axis of the aligned openings in the carrier and the cap, said ball having a slot therein extending along an equatorial circle lying in a plane containing said trunnion and the recess in the cap, the plane of said circle forming an angle of 45 with the duct, said slot extendng through an arc of one-fourth of the circumference of the sphere, a finger carried by the carrier and extending inwardly of the housing and engaging the slot, said finger being located in a diametrical plane passing through the axis of the two openings and spaced an equal distance from the opening in the carrier and the diametrical plane passing through the trunnion and the recess in the cap, whereby the finger lies at a first end of the slot when the duct is aligned with an axis passing through the openings in the cap and carrier, lies at a second end of the slot when the duct lies at an angle of about 45 with respect to the axis passing through the openings and.` lies again at the first end of the slot when the duct lies at an angle of 90 with respect to said axis, while the cap revolves through a total angle of References cited in the file of this patent UNITED STATES PATENTS 1,691,8l1 Johnson Nov. 13, 1928 1,747,550 Klimburg Feb. 18, 1930 2,558,671 Cherry June 26, 1951
