Abstract
An appliance for sealing elastic hoses with a sleeve, which is plastically deformable and slipped onto the hose, has two jaws which are movable towards and away from each other. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The same jaw has a cutting edge which projects towards the other jaw and is directed transversely of the sleeve, the cutting edge making a substantially transverse cutting indication in the sleeve and the hose when the jaws are moving towards each other.
Claims42
An appliance for mechanical sealing of hollow hoses (2) of elastic material with a sealing means (3) which is made of plastically deformable material and which is applied to the hose, said appliance (1) having two jaws (8, 9), at least one of the jaws is movable towards and away from the other jaw and the jaws crimp the sealing means (3) against the hose (2) to seal the same, characterised in that the sealing means (3) has the form of a sleeve (4) which is slipped on to the hose (2), that at least one of the jaws (8 or 9) has at least one straight bar (11) having a projecting end which projects towards the other jaw (9 or 8) and which, when at least one the jaws is moving towards the other jaw, makes an indentation (12) in the sleeve (4) and the hose (2) to reinforce the sealing thereof as well as the fixing of the sleeve on the hose, that at least one of the jaws (8 or 9) has a cutting means (13), which projects towards the other jaw (9 or 8) and which when at least one of the jaws (8, 9) is moving towards the other jaw, makes a cutting indication (14) in the sleeve (4) and the hose (2) to allow a sealing cutting of the hose (2), and that the cutting means (13) has the form of a substantially straight cutting edge (15) which projects to a greater extent than the projecting end of said at least one bar (11).
An appliance for mechanical sealing of hollow hoses (2) of elastic material with a sealing means (3) which is made of plastically deformable material and which is applied to the hose, said appliance (1) having two jaws (8, 9), both of the jaws are movable towards and away from each other and which, when moving towards each other, crimp the sealing means (3) against the hose (2) to seal the same, characterised in that the sealing means (3) has the form of a sleeve (4) which is slipped on to the hose (2), that at least one of the jaws (8 or 9) has at least one straight bar (11) having a projecting end which projects towards the other jaw (9 or 8) and which, when the jaws (8, 9) are moving towards each other, makes an indentation (12) in the sleeve (4) and the hose (2) to reinforce the sealing thereof as well as the fixing of the sleeve on the hose, that at least one of the jaws (8 or 9) and which, when the jaws (8, 9) are moving towards each other, makes a cutting indication (14) in the sleeve (4) and the hose (2) to allow a sealing cutting of the hose (2), and that the cutting means (13) has the form of a substantially straight cutting edge (15), which projects to a greater extent than the projecting end of said at least one bar (11).
A system for sealing and allowing separation of a hollow hose between containers, comprising:
- a hollow hose and a plastically deformable sealing device on the hose located between containers;
- and
- a hand-held appliance having two jaws movable relative to each other, at least one of the jaws supporting at least one bar having a projecting end that projects toward the other jaw, and at least one of the jaws supporting at least one cutting indication projection configured to make a cutting indication, the cutting indication projection being different from the bar and, when fully engaged, projects past the projecting end of the at least one bar, the bar configured to create an indentation in the sealing device when the jaws are moved relative to each other.
A system for sealing and allowing separation of a hollow hose between containers, comprising:
- a hollow hose between containers and a sealing device that surrounds a portion of the hose;
- and
- a hand-held appliance having two jaws movable relative to each other, at least one of the jaws supporting at least one cutting projection configured to make a substantially transverse cut through the hose, one of the jaws configured to create an indentation in the hose with said sealing device to reinforce the sealing of the hose and fixing of the sealing device on the hose when said jaws are moved relative to each other, wherein:
- the one of the jaws configured to create an indentation in the hose with the sealing device is configured to cause a projecting bar to create the indentation in the hose;
- the indentation and the cut are separate from each other;
- and
- the appliance is configured to create the cut and the indentation without translational movement of the appliance along the longitudinal axis of the hollow hose.
