Abstract

A device for sealing a vessel, having a stopper for closing the vessel, the stopper including a sealing mechanism for sealing with the vessel; an attachment ring for attaching the stopper to the vessel, the ring has a sleeve provided with a radial flange with a central opening, and first attachment mechanism to be attached to the vessel; a cover having a radial disc and second attachment mechanism; a blocking element having an axial wall and a complementary attachment mechanism engaging in the assembled state with the second attachment mechanism. The axial wall has on one portion of its periphery a tearable tab defined between two grooves forming bridges of thin material, the tab having, on one side, a gripping portion and ending, on the opposite side, with a flared portion such that, once torn, the axial wall opens out along the entire height allowing removal of the blocking element.

First claim

The invention claimed is:

1 . A device for sealing a fluid product vessel comprising a collar provided with an upper axial edge, said sealing device comprising:
a stopper comprising a radial plate and an axial drum, said axial drum penetrating inside said collar during assembly, said stopper comprising sealing means for sealing with said vessel, an attachment ring for attaching said stopper on said collar, said attachment ring comprising a cylindrical axial sleeve provided on the upper side with a radial flange extending radially inwards and comprising a central opening, said cylindrical axial sleeve comprising, on the lower side, first attachment means to be attached to said collar of said vessel, a cover comprising a radial disc and a cylindrical axial envelope extending axially downwards from said radial disc, said cover comprising second attachment means, a blocking element comprising a cylindrical axial wall and complementary attachment means engaging in the assembled state with said second attachment means of said cover, wherein said axial wall comprises, on one portion of its periphery, a tearable tab defined between two grooves forming bridges of thin material, said tearable tab comprising, on one side, a gripping portion and ending on the opposite side by a flared portion, such that once torn, said axial wall opens out along the entire height thereof, thus making it possible to remove said blocking element from said sealing device; wherein said radial plate comprises a central tapping zone defined inside an axial ring; and wherein the radially external edge of said axial ring is conic by flaring upwards.

2 . The device according to claim 1 , wherein said axial drum of said stopper comprises on its outer surface, at least one sealing bead which engages with the inside of said collar of said vessel to guarantee the sealed sealing of said vessel.

3 . The device according to claim 1 , wherein said radial plate of said stopper has an external diameter greater than the external diameter of said axial drum, and comprises at least one annular projection extending downwards which, in the sealing position, engages with said upper axial edge of said collar.

4 . The device according to claim 3 , wherein said annular projection is peripheral and is, during the assembly of said sealing device on said collar of said vessel, flattened on said upper axial edge of said collar for sealing with said vessel.

5 . A device for sealing a fluid product vessel comprising a collar provided with an upper axial edge, said sealing device comprising:
a stopper comprising a radial plate and an axial drum, said axial drum penetrating inside said collar during assembly, said stopper comprising sealing means for sealing with said vessel, an attachment ring for attaching said stopper on said collar, said attachment ring comprising a cylindrical axial sleeve provided on the upper side with a radial flange extending radially inwards and comprising a central opening, said cylindrical axial sleeve comprising, on the lower side, first attachment means to be attached to said collar of said vessel, a cover comprising a radial disc and a cylindrical axial envelope extending axially downwards from said radial disc, said cover comprising second attachment means, a blocking element comprising a cylindrical axial wall and complementary attachment means engaging in the assembled state with said second attachment means of said cover, wherein said axial wall comprises, on one portion of its periphery, a tearable tab defined between two grooves forming bridges of thin material, said tearable tab comprising, on one side, a gripping portion and ending on the opposite side by a flared portion, such that once torn, said axial wall opens out along the entire height thereof, thus making it possible to remove said blocking element from said sealing device; wherein said radial plate comprises a central tapping zone defined inside an axial ring; and wherein, in the assembled state of said sealing device, said radial flange of said attachment ring is positioned on said radial plate of said stopper, said central opening receiving said axial ring and said tapping zone of said stopper.

6 . The device according to claim 5 , wherein the radial edge of said central opening is snap-fitted on said radially external conic edge of said axial ring.

7 . The device according to claim 1 , wherein said first attachment means of said attachment ring are snap-fitting means, comprising at least one radial profile extending radially inwards.

8 . The device according to claim 7 , wherein said first attachment means comprise one single radial profile which extends over the entire periphery of said cylindrical axial sleeve.

9 . A device for sealing a fluid product vessel comprising a collar provided with an upper axial edge, said sealing device comprising:
a stopper comprising a radial plate and an axial drum, said axial drum penetrating inside said collar during assembly, said stopper comprising sealing means for sealing with said vessel, an attachment ring for attaching said stopper on said collar, said attachment ring comprising a cylindrical axial sleeve provided on the upper side with a radial flange extending radially inwards and comprising a central opening, said cylindrical axial sleeve comprising, on the lower side, first attachment means to be attached to said collar of said vessel, a cover comprising a radial disc and a cylindrical axial envelope extending axially downwards from said radial disc, said cover comprising second attachment means, a blocking element comprising a cylindrical axial wall and complementary attachment means engaging in the assembled state with said second attachment means of said cover, wherein said axial wall comprises, on one portion of its periphery, a tearable tab defined between two grooves forming bridges of thin material, said tearable tab comprising, on one side, a gripping portion and ending on the opposite side by a flared portion, such that once torn, said axial wall opens out along the entire height thereof, thus making it possible to remove said blocking element from said sealing device; and wherein the internal diameter of said cylindrical axial envelope of said cover is identical to or very slightly greater than the external diameter of said cylindrical axial sleeve of said attachment ring, such that in the assembled state of the sealing device, said cylindrical axial envelope is positioned around said cylindrical axial sleeve with no or little clearance between them.

10 . The device according to claim 1 , wherein said second attachment means of said cover comprise one or more projection(s) extending radially outwards.

11 . The device according to claim 10 , wherein said complementary attachment means of said blocking element comprise one or more profiles extending radially inwards, said profiles being snap-fitted on said one or more projection(s) forming said second attachment means of said cover.

12 . The device according to claim 1 , wherein said axial wall of said blocking element comprises, on its lower axial edge, an annular radial wall extending radially inwards, the radially internal edge of said annular radial wall having a diameter less than the external diameter of said cylindrical axial sleeve of said attachment ring, and less than the external diameter of said vessel.

13 . The device according to claim 1 , wherein said device has no metal.

14 . An assembly comprising a fluid product vessel comprising a collar and a sealing device according to claim 1 , to attach and hold a stopper on said collar.
