A machine for forming filled sealed pouches from a continuously moving sealable web of material includes a first sealing station for forming a longitudinal seal along a side edge of the web, and a horizontal sealing station for forming a plurality of transverse seals in the web. The horizontal sealing station includes a pair of conveyors each carrying jaws that mate along a sealing path to form the transverse seals. A method of forming filled sealed pouches from a continuously moving sealable web of material is also described.

Method and apparatus for making a continuous series of filled pouches

A disposable spray dispensing assembly for liquid materials includes a container that comprises an aerosol can, and a spray head initially detached from the container. A cap is connected to the container and includes a central recess extending into the chamber and presenting a hole. A tube within the chamber is connected to a cylindrical wall surrounding the recess. The cap is non-releasably connected to the container and hinders refilling of the chamber in order to reduce the likelihood that the chamber might contain a material different than the contents indicated on the container's label.

Single use spray dispensing assembly

A container and cap assembly includes a double barrel dispensing container having two side-by-side outlets, and a cap with two side-by-side closure portions for simultaneously closing both outlets when the cap is connected to the container. The cap includes two protruding orienting sections for orienting the cap relative to the container as the cap is connected to the container. The orienting sections insure that each closure portion comes into contact with the same outlet each time the cap is coupled to the container so that small quantities, if any, of materials flowing through one outlet and deposited on one closure portion of the cap cannot cross-contaminate materials in the remaining barrel after the cap is removed and then re-connected to the container after a dispensing operation.
