Abstract: A method of making a gas permeable material having a diffusive gas permeability at 0.21 atmosphere diffusive driving force in the range of about 0.5.times.10.sup.5 cm.sup.3 /100 square inches/day to about 2.times.10.sup.5 cm.sup.3 /100 square inches/day. The method comprises the step of coating a pattern of spots of a gas impermeable material onto a porous substrate, followed by a step of enlarging the pattern of spots to cover greater than about 95% of the porous substrate such that the gas permeability occurs only through openings between the pattern of spots. The gas impermeable material is preferably a hot melt adhesive and the porous substrate is preferably a nonwoven. The step of enlarging the pattern of spots includes smearing substantially circular spots into oblong spots as the pattern of spots is printed onto the porous substrate until the oblong spots partially overlap. The smearing is achieved by operating a printing screen at a surface speed higher than a draw rate of the porous substrate.

Abstract: A plastic container for multiple side-by-side stacks of fragile articles has a single blow molded body. The body has side walls and at least one internal partition extending from near a continuously rimmed open top to near a closed bottom end of the body. The partition has two spaced apart walls connected in a longitudinal plane substantially perpendicular to said at least one partition. The partition forms at least two separated compartments within the body for supporting the stacks of fragile articles. It provides resistance to squeezing the side walls so as to protect the stacks of fragile articles, and the two spaced apart walls are adapted to deform in the presence of vacuum and pressure in the compartments such that an outer perimeter dimension of the body remains substantially constant. The container also has a reclosable closure located at the continuously rimmed top end of the body.

Abstract: A method of making a honeycomb structure includes the step of intermittently slitting a sheet of material such that longitudinal slits are aligned in alternating staggered rows. Each staggered row has a lateral centerline spaced substantially uniformly from adjacent row centerlines. The longitudinal slits in each staggered row have substantially uniform lateral spaces between each slit. Another step is applying continuous stripes of adhesive laterally across a top side and a bottom side of the sheet such that each stripe is spaced apart longitudinally and centered on a row of slits. The stripes alternate between the top side and the bottom side. Still another step includes pleating the sheet such that pleats run longitudinally. Each pleat has a top fold and a bottom fold aligned with a longitudinal slit. Yet another step involves gathering the pleats together in a closed stack and compressing the stack to cause the stripes of adhesive to bond the pleats together at adhesive contact points.

Abstract: A method of providing halotherapy to the upper portion of the lower respiratory tract includes the steps of operating a dispenser and inhaling. The dispenser contains a dry sodium chloride powder. The user operates the dispenser to release a dosage of the powder for inhalation when the dispenser is aimed into the user's mouth. The user then inhales the dosage of powder through the mouth. Because the powder has a particle size range enabling the powder to target the upper portion of the lower respiratory tract without entering the user's lungs, the dosage of the dry powder provides a concentration at the upper portion sufficient to provide effective halotherapy. The preferred particle size range is from about 5 microns to about 20 microns. The preferred dosage is about 3 milligrams of powder.
