Sealing means, kit and method for sealing of hollow hoses of flexible material

1. A sealing member comprising a plastically deformable material for mechanical sealing of hollow hoses of elastic material in use with an appliance having at least two jaws, at least one of which is movable towards and away from the other and which, when moving towards each other, crimp the sealing member against the hose and cut the hose and the sealing member for contamination-tight sealing of the hose, wherein the sealing member comprises at least two sealing members, each of which has two opposite ends and an opening that extends between said ends to allow the sealing members to be slipped onto the hose to be seated, the sealing members being adapted such that the portions of a in sealing member that border the opening of said sealing member overlap corresponding portions of a second sealing member when the sealing members are arranged around the hose to be sealed and wherein a surface extending between a first side and a second side of said opening of at least one of said sealing members spans 230-270° of a circle circumscribing said sealing members.

2. A sealing member according to claim 1 wherein a portion of at least one of the at least two sealing members that borders one side of the opening of said sealing members overlaps a corresponding portion of the other sealing member on the opposite side of the opening and spans 361-390° of a circle circumscribing said sealing member.

3. A sealing member as claimed in claim 1 , wherein each sealing member consists of a substantially cylindrical element with opposite ends and with an opening that extends between said ends to allow application to the hose.

4. A sealing member of claim 1 wherein the at least two sealing members have a surface extending between a first side and a second side of said opening of each of said sealing members spans 230-270° of a circle circumscribing said sealing members.

5. A sealing member of claim 1 wherein at least one of said sealing members is provided with positioning means for positioning said sealing members at a desired position relative to one another when disposed around the hose to be sealed.

6. A sealing member of claim 1 wherein at least one of said sealing members is provided with a bent portion, the bent portion extending outwards from the surface of the sealing member and being configured such that an edge around said opening of said second sealing member abuts against said bent portion when said first and second sealing members are positioned with the desired overlap around the hose to be sealed.

7. A sealing member of claim 1 wherein the sealing members are adapted such that said overlap between the sealing members when disposed around the hose to be sealed, has a length that exceeds the material thickness of said sealing members.

8. A sealing member of claim 1 wherein the overlap on the respective sides of said opening having a length that exceeds the material thickness of said sealing members.

9. The sealing member of claim 1 further comprising the hose having a first and second end, the first end of the hose being attached to a first component and the second end of the hose being attached to a second component and the sealing members being positioned over the hose between it first and second end.

10. A method for mechanical sealing of hollow hoses by means of an appliance having at least two laws, at least one of which is movable towards and away from each other, comprising the steps of

providing a hose having a first and second end, the first end of the hose being attached to a first component, the second end of the hose being attached to a second component,

providing a sealing member made of a plastically deformable material, the sealing member comprising two sealing members, each of which has two opposite ends and an opening that extends between said ends to allow the sealing members to be slipped onto the hose between its first and second end;

arranging the respective sealing members on the hose in such a manner that a portion of one sealing member overlap a corresponding portion of the other sealing member by a length that exceeds the material thickness of said sealing member;

crimping the sealing members against the hose by means of said appliance for contamination-tight sealing and

cutting the sealing members and hose.

11. A kit for mechanical sealing of hollow hoses of elastic material, the kit comprising a sealing member formed of a plastically deformable material for mechanical sealing of hollow hoses of elastic material wherein the sealing member is at least two sealing members each in the form of a cylindrical sleeve haying a length and which has two opposite ends and an opening that extends the length of the sleeve between said ends to allow the at least two sealing members to be slipped onto the hose to be sealed and an appliance having at least two jaws, at least one of which is movable towards and away from the other and which, when moving towards each other, crimp the sealing members against the hose for contamination-tight sealing of the same, wherein at least one of the jaws of the appliance has at least one bar which projects towards the other jaw and which, when the jaws are moving towards each other, makes an indentation in the sealing members and the hose to reinforce the sealing thereof as well as the fixing of the sealing members on the hose, and wherein at least one of the jaws has a cutting means, which projects towards the other jaw and which, when the jaws are moving towards each other, makes a cutting indication in the sealing members and the hose to allow the hose to be cut in a sealing manner.

12. The kit of claim 11 further comprising the hose having a first and second end, the first end of the hose being attached to a first component and the second end of the hose being attached to a second component and the sealing members being positioned over the hose between its first and second end.
