Abstract: A insulation device includes an enclosure defining a cavity which is filled with a binderless, loose, discrete, divided insulation material. An uncured binder is homogeneously dispersed through the insulation filling material prior to installing the insulation material in the enclosure. The binder is cured after the insulation material is installed in the cavity to prevent the shifting or settling of the insulation material within the cavity. The insulation device can be made by forming an opening into the cavity of the enclosure, injecting binderless, loose, discrete, divided insulation material into the enclosure cavity and concurrently applying an uncured binder on the insulation material as it is being injected into the enclosure cavity to homogeneously distribute the uncured binder throughout the insulation material being injected into the enclosure cavity, and closing the opening of the enclosure.

Abstract: A web of plastic bags is made from rollstock of a strong heat sealable plastic material for the bulk storage and dispensing of liquids by passing two aseptic sheets of the material into a press that heat bonds the longitudinal edges and laterally across the sheets to form a web of sealed bags. The longitudinally bonded strips are perforated to engage sprocket wheels which draw the web of bags to a position at which a dispensing fitment is bonded to the outer surface of one sheet, and then to a station which cuts a short lateral slit across only one sheet. The web then passes over and hangs from the sprocket so that the slit slightly opens to permit filling of the bag from the bottom up with a long pointed diving fill tube that isolates the bag contents from the slit. The area around the slit is then heat sealed against the opposite side of the bag to prevent leakage of the bag contents and the admission of contaminants into the bag.

Abstract: An improved infusion bag for preparing an infusion of tea or other infusible substances, comprising a sachet member of liquid-permeable sheet material and a pull string. The pull string is joined at the upper apex of the sachet. At least one ventilative slit is provided below the joint point of the string and the upper apex of the sachet. The sachet can be folded into a generally tetragonal shape. After steeping, and by the action of withdrawing and submerging, the infusible substance swells and sinks to the lower apex of the sachet. The improved infusion bag makes the infusible substance less compacted and overcomes the constraint due to the capillarity of the liquid-permeable sheet material itself and the interface capillarity of the mass of the infusible substance. This gives a higher quantity and higher concentration of infusion liquor.
