A machine for dispensing a sealing compound to an area of application and a method of sealing cracks in pavement is provided. The machine includes a frame structure, a disposable container removably mounted to the frame structure, a discharge tube member rupturing the opening in the bottom of the container, and a controllable valve in the discharge tube member to control the flow of the sealing compound from the disposable container to the area of the application. The frame structure may support a blower to clean the crack and supports a squeegee member mounted to a box member into which the sealing compound is received from the discharge tube member, to evenly spread the sealing compound within the crack and in the nearmost areas.

[ What is claimed is:] [1.]1. A machine for dispensing a sealing compound at an area of application, comprising:(a) a frame structure;(b) a disposable container removably mounted on said frame structure;(c) a sealing compound pre-filled into said disposable container prior to mounting said disposable container on said frame structure, said disposable container having walls forming a closed chamber containing said sealing compound whereby said sealing compound is prevented from being inadvertent discharge from said disposable container and from being brought into contact in surrounding atmosphere;(d) discharge means on said frame structure for puncturing said disposable container, said discharge means including a tube member provided with a sharp edge at first end thereof and having walls forming an opening in proximity to said sharp edge, said tube member having a second end for discharging said sealing compound;(e) a pressing member secured to said frame structure for bringing said disposable container into engagement with said sharp edge of said tube member of said discharge means thereby forming a fluid communication path for said sealing compound between interior of said closed chamber of said disposable container and said second end of said tube member of said discharge means; and,(f) squeegee means pivotally coupled to said frame structure for spreading said sealing compound into the area of application, said squeegee means including a box member having side walls forming respective top and bottom openings at upper and lower edges of said side walls, and a squeegee member attached to said lower edges of said side walls of said box member, said top opening of said box member being aligned with said second end of said tube member of said discharge means for receiving said sealing compound in said box member and applying said sealing compound to the area of application.
