Viscous material selective packet method
View Patent ↗A viscous material dispenser comprises a container having at least two opposing sidewalls; a first closure end; and a second closure end; the sidewalls and closure ends defining an enclosure, and at least one closure end comprising an expressing shape and at least one sidewall comprising a crease running from the expressing shaped closure end to the other closure end to permit folding the container at the crease to express a content from an interior of the container through the expressing shaped closure end to an exterior.
1. A method of applying a sealant to substantially empty a sealant packet without retain unused sealant, comprising:
identifying a sealant job;
identifying an amount of sealant to complete the identified sealant job without substantial unused sealant;
selecting a packet containing only an amount of sealant that substantially matches the identified amount of sealant to accomplish the identified job without substantial unused sealant from a sealant kit containing a plurality of sealed packets wherein at least one packet differs in size and contains a different amount of sealant than at least one other packet; and
folding a semi-rigid plastic backing to express sealant from the packet, to substantially empty the packet and to complete the job.
2. The method of claim 1 , wherein the at least one packet has dimensions of 8 cm by 6 cm or smaller.
3. The method of claim 1 , wherein the at least one packet has dimensions of 20 cm to 4 cm by 15 cm to 2 cm with a filled thickness of 0.5 cm to 2 cm.
4. The method of claim 1 , wherein the at least one packet has dimensions of 20 cm by 15 cm or smaller, containing an amount of caulk sealant to seal an identified job without substantial unused sealant.
5. The method of claim 1 , wherein the semi-rigid plastic backing is flexible to be collapsed against itself and creased at a crease line.
6. The method of claim 1 , wherein the at least one packet holds a sealant comprising an RTV composition.
7. The method of claim 1 , wherein the at least one packet holds a sealant comprising a polysiloxane component comprising a mixture or reaction product of (i) a polysiloxane polymer having hydrolysable substituent groups and (ii) a polyfunctional silicon compound having two or more hydrolysable substituent groups.
8. The method of claim 1 , wherein the at least one packet holds a sealant comprising a polysiloxane component comprising a mixture or reaction product of (i) a polysiloxane polymer having hydrolysable substituent groups and (ii) a polyfunctional silicon compound having two or more hydrolysable substituent groups and includes a filler and a condensation cure catalyst.
9. The method of claim 1 , wherein the at least one packet comprises a longitudinal axis and an interior, the packet including a top sidewall including the semi-rigid plastic backing, a bottom sidewall, a first closure forming a downstream end of the packet and a second closure forming an upstream end of the packet, a dispensing extension to the semi-rigid plastic backing in a nozzle form extending outwardly from the backing and having a flow passageway in fluid communication with the interior.
10. The method of claim 9 , comprising a sealant contained in an interior of the at least one packet, the semi-rigid plastic backing being fabricated out of a flexible material whereby the packet may be manually folded to squeeze the sealant as an applied bead out of the packet and onto a selected substrate surface.
