Abstract
A flexible extender nozzle that can be used in conjunction with a variety of different caulk cartridges and caulking guns. The flexible extender nozzle has a flange which is adapted to allow the extender nozzle to be operably sandwiched between the caulk cartridge and the caulking gun. The flexible extender nozzle also contains a raised seal ring which is adapted to form a seal on a variety of cartridges.
Claims27
An apparatus for adjusting the dispensation of material from a container when said container is supported by a dispenser comprising:
- a tube having an inner diameter, a proximal end portion and a distal end portion, said proximal end portion adapted to receive said material from said container, said distal end portion adapted to dispense said material;
- a flange attached to said proximal end portion of said tube, said flange operably sandwiched between said container and said dispenser, said flange adapted to keep said apparatus in contact with said container during said dispensation of said material from said container;
- and
- a raised seal having a perimeter, said seal attached to said flange, said seal adapted to seal said apparatus against said container during said dispensation of said material from said container.
A plastic apparatus for adjusting the dispensation of caulk from the nozzle of a cylindrical caulk cartridge when said cartridge is supported by a caulk gun comprising:
- a flexible tapered dispensation tube having an inner diameter, a proximal end portion and a narrower distal end portion, said inner diameter of said tube being sized to operably permit said nozzle of said cartridge to be positioned within said tube, said proximal end portion of said tube adapted to receive said caulk from said nozzle of said cartridge, said distal end portion of said tube adapted to dispense said caulk;
- a scalloped flange attached to said proximal end portion of said tube, said flange having a plurality of concave portions, said flange operably sandwiched between said cartridge and said gun, said flange adapted to keep said apparatus in contact with said cartridge during said dispensation of said caulk from said cartridge;
- and
- a raised seal ring having a perimeter, said seal ring attached to said flange and extending away from said flange and said proximal end portion of said tube, said seal ring adapted to seal said apparatus against said caulk container during said dispensation of said caulk from said caulk container.
A system for dispensing material comprising:
- a container containing said material for dispensing;
- a flexible extender nozzle having a tube, a flange, and a raised seal, said extender nozzle adapted to promote elongated dispensation of said material from said container;
- and
- a dispenser adapted to operably support said container and said extender, said dispenser also adapted to operably create a sealable contact between said container and said extender.
An elongated tube having inner and outer diameters and proximal and distal ends,
- a flange projecting radially outwardly of said tube adjacent said proximal end thereof and having an upper surface facing toward said tube distal end and a lower surface facing away from said tube distal end, and
- an annular sealing ring mounted on said lower surface of said flange and projecting away therefrom.
A flexible nozzle extension comprising:
- an elongated tube having inner and outer diameters and proximal and distal ends and tapering uniformly inwardly from adjacent said proximal end to adjacent said distal end thereof;
- a flange having a scalloped configuration and projecting radially outwardly of said tube adjacent said proximal end thereof and having an upper surface facing toward said distal end of said tube and a lower surface facing away from said distal end of said tube;
- an annular sealing ring mounted on said lower surface of said flange and projecting away therefrom,
- said scalloped configuration including a plurality of concave portions with inner extremities of said portions being disposed outwardly of said annular sealing ring;
- and
- and said tube, said flange and said annular sealing ring being form integrally of a flexible plastic material.
