Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
268 words
A bidirectional joining device with an integral passage between a first enclosure having a flange serving as a seat for a first plug provided with a first gasket and a second enclosure having an opening, a second plug and a second gasket, whereby the first gasket is able to form the sealing between the first plug and the gasket and the first plug and the second plug when the latter are joined together, wherein the second enclosure has an opening provided with a lateral edge, the second plug has a peripheral edge perpendicular to the axis of the two plugs, a side wall having a convex portion and a bottom, the second gasket has an external lateral face, an internal lateral face and an upper face turned towards the outside of the second enclosure, said external lateral face being sealingly and not-detachably fixed to the lateral edge of the second enclosure, said inner lateral face having a first bead able to cooperate with the convex portion of the second plug to ensure the joining together of said second plug and the drum by locking the bead between the convex portion and the edge, said upper face being provided with an external annular contact area which is able to ensure by deformation sealing between the drum and the flange of the second enclosure when the two enclosures are joined together, a second annular contact area ensuring by elastic deformation the covering of the periphery of the peripheral edge of the second plug and sealing means between the upper face of the gasket and the peripheral edge of the plug.
Claim 2
Dependent Claim
268 words
A bidirectional joining device with an integral passage between a first enclosure having a flange serving as a seat for a first plug provided with a first gasket and a second enclosure having an opening, a second plug and a second gasket, whereby the first gasket is able to form the sealing between the first plug and the gasket and the first plug and the second plug when the latter are joined together, wherein the second enclosure has an opening provided with a lateral edge, the second plug has a peripheral edge perpendicular to the axis of the two plugs, a side wall having a convex portion and a bottom, the second gasket has an external lateral face, an internal lateral face and an upper face turned towards the outside of the second enclosure, said external lateral face being sealingly and not-detachably fixed to the lateral edge of the second enclosure, said inner lateral face having a first bead able to cooperate with the convex portion of the second plug to ensure the joining together of said second plug and the drum by locking the bead between the convex portion and the edge, said upper face being provided with an external annular contact area which is able to ensure by deformation sealing between the drum and the flange of the second enclosure when the two enclosures are joined together, a second annular contact area ensuring by elastic deformation the covering of the periphery of the peripheral edge of the second plug and sealing means between the upper face of the gasket and the peripheral edge of the plug.
Claim 3
Dependent Claim
114 words
A device according to claim 1, wherein the gasket of the second enclosure has an annular groove made in the internal lateral face partly separated from the bead and from the remainder of the gasket in order to permit a certain pivoting of the bead by elastic deformation under the action of the convex portion of the second plug during the penetration of the latter and a third internal contact area provided on the upper face of the gasket at the bottom of said bead in such a way that this third contact area can pivot at the same time as the bead before being compressed by the peripheral edge of the second plug.
Claim 4
Dependent Claim
50 words
A device according to claim 1, wherein the second enclosure comprises a drum, whose side wall is provided with an annular groove turned towards the inside of the drum, whilst the second gasket has on its outer lateral face a second bead able to penetrate the groove of the drum.
Claim 5
Dependent Claim
27 words
A device according to claim 3, wherein the second gasket has an internal hoop applied to the internal lateral face thereof with respect to the second bead.
Claim 6
Dependent Claim
47 words
A device according to claim 3, wherein the third internal contact area is, prior to pivoting, inclined towards the outside of the drum with respect to the axis thereof and after pivoting it is inclined towards the inside of the drum with respect to the axis thereof.
Claim 7
Dependent Claim
14 words
A device according to claim 1, wherein the contact areas are constituted by lips.
