Abstract
The polymeric substance delivery method and device, in which the outflow is determined from a first container (5) of a monomeric substance able to polymerize autonomously upon air contact, and eventually, the outflow from a second container (7) is determined of a hardening substance able to accelerate the polymerization of the monomeric substance, by sending the same hardening substance towards a mixing zone of the hardening substance with the same monomeric substance.
Claims17
A method for extruding a polymeric substance from a device that has a first pressurized container holding a monomeric substance that polymerizes upon air contact and a second container holding a hardening substance that accelerates polymerization of the monomeric substance, the method comprising the steps of:
- manually pumping air at a pressure higher than atmospheric pressure into the second container;
- selectively causing an outflow of the monomeric substance from the first pressurized container to a mixing zone of the hardening substance and the monomeric substance;
- and
- selectively causing an outflow of the hardening substance from the second container to the mixing zone.
A method for extruding a polymeric substance from a device that has a first pressurized container holding a monomeric substance that polymerizes upon air contact and a second container holding a hardening substance that accelerates polymerization of the monomeric substance, the method comprising the steps of:
- providing a pressure substantially equal to atmospheric pressure in the second container;
- selectively causing an outflow of the monomeric substance from the first pressurized container to a mixing zone of the hardening substance and the monomeric substance;
- and
- selectively causing an outflow of the hardening substance from the second container to the mixing zone under the effect of the force of gravity.
A device extruding a polymeric substance, comprising:
- a first pressurized container for holding a monomeric substance that polymerizes upon air contact;
- a second container for holding a hardening substance that accelerates polymerization of the monomeric substance;
- a first conduit that conducts the monomeric substance to a mixing zone where the hardening substance mixes with the monomeric substance;
- a second conduit that conducts the hardening substance to the mixing zone;
- and
- a manual pump that pumps air into the second container up to a pressure that exceeds atmospheric pressure.
A device extruding a polymeric substance, comprising:
- a first pressurized container for holding a monomeric substance that polymerizes upon air contact;
- a second container for holding a hardening substance that accelerates polymerization of the monomeric substance;
- a first conduit that conducts the monomeric substance to a mixing zone where the hardening substance mixes with the monomeric substance;
- and
- a second conduit that conducts the hardening substance to the mixing zone,
- the first and second conduits being coaxial at least adjacent to the mixing zone.
