Abstract
Rotatably engaged to the filter (4, 104) of a pressurized-steam container (5, 105) is a closing member (2, 102) provided at the upper part thereof with an operating cap (6, 108). Through 180.degree. rotations of the closing member (2, 102) the fluid communication between the container (5, 105) and the surrounding environment via a filling header (8, 109) having a supply opening (110) at the upper part thereof, is selectively opened and closed. The closing member (2, 102) is driven in rotation by means of a grip element (20, 117) that, upon command of a diaphragm (17, 113) submitted to the inner pressure of the container (105), is moved to an embedded condition in the presence of pressure in the container, thereby being inaccessible to the user.
Claims15
A device for filling and closing pressurized-steam containers comprising:
- a closing member (2) operatively and sealingly engaged to a filler (4) exhibited by a container (5);
- an operating cap (6) integral with the closing member (5) and rotatable so as to bring the closing member from a sealing position in which said filler (4) is hermetically closed to the environment to a supply position in which the filler (4) is in communication with the environment, said device further comprising:
- a covering envelope (9) fastened to the container (5), arranged to accommodate the operating cap (6) and the filler (4) at least partly;
- a filling header (8) exhibiting a supply opening (8a) oriented upwardly with respect to the covering envelope (9) and communicating with a connecting portion (7a) opening to the closing member (5) at said filler (4), said connecting portion (7a) being selectively connected to and hermetically separated from the filler (4) when the closing member (2) is in the supply position and sealing position respectively;
- safety means (16) for inhibiting movement of the closing member (2) from the sealing position to the supply position when pressure within the container (5) exceeds a predetermined value.
A device for filling and closing pressurized-steam containers of the type comprising:
- a closing member (102) provided with a threaded shank (103) engaged in a filler (104) exhibited by a container (105) and a circumferential flange (106) projecting radially with respect to the threaded shank (103) beyond a free end (104a) of the filler (104);
- an operating cap (108) integral with the closing member (102) at the upper part thereof;
- a seal (107) operatively interposed between the circumferential flange (10) and the free end (104a) of the filler (104), said device further comprising:
- a filling body (109) fastened to the container (105) at the filler (104) thereof, which is arranged to receive said operating cap (106) at least partly and is provided at the upper part thereof with a supply opening (110);
- at least one auxiliary duct (123) bringing the inside of the container (105) into fluid communication with a connecting portion (124) limited by the inner circumferential edge of the seal (107), so that the closing member (102), following an angular rotation involving an axial displacement lower than the length of the threaded shank (103), is movable from a looking position in which the circumferential flange (106) acts in abutment on the seal (107) and a supply position in which the circumferential flange (106) is moved apart from the seal (107) in order to open a fluid communication between the inside of the container (105) and the filling body (109);
- safety means (112) for inhibiting the displacement of the closing member (102) from the locking position to the supply position when pressure within the container (105) exceeds a predetermined value.
