Meltable crack sealant packaging

摘要

A meltable crack sealant package that includes a polymeric container and a crack sealant material contained therein. The polymeric container includes a bottom portion including a rigid base and an upwardly extending rigid sidewall that terminates in and define an opening. The rigid base and upwardly extending rigid sidewall cooperate to define a reservoir. A rigid lid portion operatively engages with the bottom portion to close off the opening and thereby seal the crack sealant material within the reservoir in a watertight manner. Methods of making and using the meltable crack sealant package are also disclosed.

主权项

1. A meltable crack sealant package consisting essentially of:
a polymeric container formed of non-expanded polypropylene homopolymer, said polymeric container having a base portion and an upwardly extending sidewall that terminates in a rim that defines an opening, said polymeric container defining a receptacle; a polymeric lid formed of non-expanded polypropylene homopolymer, said polymeric lid operatively engaging with the polymeric container to close off the opening and thereby seal the receptacle in a watertight manner; and a crack sealant material contained within the sealed reservoir of the container, said crack sealant material being a solid at temperatures up to at least 100° F.; wherein said meltable crack sealant package is capable of being heated to a temperature within the range of from about 350° F. to about 450° F. to form a molten liquid material for application to pavement surfaces to seal joints and cracks therein.
