Application No. 08/345,215
whereby the rupture of said heat seal wherein the ionomer is bonded to itself
allows communication between the compartments and permits contact between the
contents of the separate compartments of said package.
26. A sterilizable mixing and dispensing package for a natural or synthetic hydratable
solid in particulate form comprising,
a flexible container body having first and second compartments,
a rupturable barrier between the compartments for allowing communication
therebetween when the barrier is eliminated to permit mixing of contents within the
package,
a natural or synthetic hydratable solid in particulate form in the first compartment,
said first compartment having a wall formed from a porous polymeric sheet for
allowing the entry of a gas into the first compartment through the pores in the sheet for
sterilizing the particulate solid in said first compartment when the gas contacts the
particulate solid therein,
the second compartment has walls formed from a plastic resin that provides a
watertight enclosure,
water stored in said second compartment,
said rupturable barrier being constructed and arranged to be opened by a person
to allow the water in the second compartment to mix with the particulate solid in the first
compartment for dispersing the particulate solid in the water to thereby form an aqueous
dispersion with the package, and
the porous polymeric sheet and plastic resin confine the aqueous dispersion
within the package after mixing whereby the aqueous dispersion can be expelled from
the package onto a surface through an outlet in the package other than the pores in the
porous polymeric sheet.
33. A sterilizable mixing and dispensing package for a wound dressing,
comprising,
a flexible pouch having a pair of compartments with a rupturable barrier between
the compartments to allow mixing of material contained in the compartments after the
barrier is ruptured,
said compartments include a water-containing compartment formed from plastic
film and,
a hydrocolloid-containing compartment comprising a porous flexible sheet
adapted to admit a sterilizing gas through pores in the flexible sheet for sterilizing the
hydrocolloid contained therein, and
after the barrier is ruptured the porous sheet and plastic film confine the
hydrocolloid and water within the package, allowing a wound dressing formed from the
mixture of the hydrocolloid and water to be expelled from the package onto a wound
through an opening in the package.
