  • Patent number: 6749876
    Abstract: Packaged food articles of improved appearance and stackability are described such as a refrigerated active cultured dairy product. Each packaged food article comprises an unpressurized, imperforate container having an opening, wherein the container is fabricated from a material having a low gas permeability. A quantity of gas releasing food stuff, such as a live cultured dairy product, is disposed within and partially fills the container defining a headspace volume which is not filled with the food stuff. A peelable flexible seal membrane overlays and seals the opening. An initial headspace gas is enriched with the gas released from the food stuff, with the initial headspace gas being adapted to permeate the packaging material at a rate greater than both the rate in which gas is released from the food stuff within the container and the rate in which air permeates into the container, thereby avoiding outward bowing of the flexible seal during the shelf life of the packaged food article.

  • Patent number: 6629402
    Abstract: A method or process for substituting an inert gas or blend of inert gases for ambient air in the head space of a container filled with leftover oil-based finish prior to sealing the lid. Even a tightly sealed container of leftover paint, stain, varnish, or other oil-based finish, will thicken, gel, or skin over with time. This occurs because the oxygen that is sealed in the storage container continues to react with oil-based finishes. The process involves using an aerosol can filled with the inert gas or blend of gases to displace the oxygen from a container that has leftover oil-based finish in it. After the oxygen is flushed out of a container with the gas, the lid is sealed tightly. The inert gas or blend must be heavier than oxygen and sink down to block oxygen from the liquid surface. Because gas or blend is heavier than oxygen, it will separate the liquid surface from any oxygen that may remain in a container.

  • Patent number: 6533564
    Abstract: An apparatus for continuously forming thermoplastic adhesive cartridges. A molten thermoplastic adhesive supply provides a supply of molten adhesive to a pump downstream from the molten thermoplastic adhesive supply. The pump then provides a molten thermoplastic adhesive melt stream which passes through a screen filter downstream from the pump to prevent the discharge of impurities in the molten thermoplastic adhesive melt stream from the pump. A temperature-controlled conduit downstream from the pump then lowers the temperature of the molten plastic melt stream to closely above its softening point. A continuous molder located downstream from the melt pump for receives the molten plastic melt stream from the melt pump to form the thermoplastic adhesive cartridge continuously.

  • Patent number: 6531085
    Abstract: We have determined that strength characteristics of elastic strand improve when the strand is heated. Thus, the present invention is directed to improving strength characteristics of an elastic strand by heating the strand. The strand may be heated by thermal conduction and/or convection, by irradiative methods using, for example, infrared or microwave radiation, or some combination of these. If the elastic strand is made at a location different from the location where the strand is used as a raw material, the strand may be heated at either location, or both locations. Furthermore, the strand may be heated in-line, i.e. as part of the process that makes the strand or the process that uses the strand as a raw material, or off-line, i.e. in a step separate from either of the aforementioned processes. Finally, in addition to heat treating the strand, the strand's exposure to water or water vapor may be regulated to reduce or eliminate strength degradation.
