Vapor phase corrosion inhibitor product and method containing a desiccant

The combination of a closed container having corrodible items and a product therein for inhibiting corrosion of such items, said product comprising:

• (a) a sealed envelope;
• (b) a powdered solid composition capable of producing and releasing a vapor phase corrosion inhibiting compound contained in said envelope;
• (c) said envelope being formed from a sheet material which is impermeable to said contained powdered solid composition but porous to the released vapor phase corrosion inhibiting compound released therefrom, whereby the vapor phase corrosion inhibiting compound produced and released by said powdered solid composition leaves the sealed envelope and permeates the environment of the closed container to protect the corrodible items therein;
• and
• (d) said sheet material comprising a non-woven fibrous fabric of spun-bonded polyolefin.

The combination of a closed container having corrodible items and a product therein for inhibiting corrosion of such items, said product comprising:

• (a) a sealed envelope;
• (b) a powdered solid composition capable of producing and releasing a vapor phase corrosion inhibiting compound contained in said envelope;
• (c) said envelope being formed from a sheet material which is impermeable to said contained powdered solid composition but pervious to the released vapor phase corrosion inhibiting compound released therefrom, whereby the vapor phase corrosion inhibiting compound produced and released by said powdered solid composition leaves the sealed envelope and permeates the environment of the closed container to protect the corrodible items therein;
• and
• (d) said sheet material comprising a fabric formed from fibers which are selected from the group consisting of:
• nylon, polytetrafluoroethylene, polyethylene, polyolefins, polyesters, or polyamides.

A product adapted to be used for inhibiting corrosion of corrodible items within closed containers, said product comprising:

• (a) a plurality of sealed envelopes serially attached to one another along their edges to form a sheet-like array of said envelopes, said array of envelopes comprising two overlying sheets joined to one another along a grid-like pattern to form the individual envelopes between the joints of the grid;
• (b) a powdered solid composition capable of producing and releasing a vapor phase corrosion inhibiting compound positioned within and contained in each sealed envelope in said array;
• (c) said sheet material being impermeable to said powdered solid composition, but porous to the released vapor phase corrosion inhibiting compound released from the powdered solid composition, whereby the vapor phase corrosion inhibiting compound produced and released by the powdered solid composition leaves the envelopes in the array and permeates the environment of a closed container of corrodible items;
• and
• (d) said sheet material comprising a non-woven fibrous fabric of spun-bonded polyolefin.

A method of inhibiting the corrosion of corrodible items within closed containers, said method comprising:

• (a) enclosing in a sealed envelope a powdered solid composition capable of producing and releasing a vapor phase corrosion inhibiting compound and wherein the envelope is formed from a non-woven fibrous spun-bonded polyolefin fabric impermeable to the powdered solid but porous to the vapor phase corrosion inhibiting compound released therefrom;
• (b) placing the sealed envelope of powdered solid composition in a container of corrodible items;
• and
• (c) sealing the container to maximize the corrosion inhibiting effects of the vapor phase compound produced and released therein.

A method of inhibiting the corrosion of corrodible items within closed containers, said method comprising:

• (a) wrapping a corrodible item in a sheet of non-woven fibrous fabric of spun-bonded polyolefin formed as a plurality of sealed envelopes serially attached to one another along their edges to form an array of said envelopes, said array of envelopes comprising two overlying sheets joined to one another along a grid-like pattern to form the individual envelopes between the joints of the grid, and with each sealed envelope in said array containing a powdered solid composition positioned therein capable of producing and releasing a vapor phase corrosion inhibiting compound, and said sheet material being impermeable to said powdered composition, but porous to the vapor phase corrosion inhibiting compound released from the powdered composition, whereby the vapor phase corrosion inhibiting compound leaves the envelope and permeates the surrounding environment;
• (b) placing the wrapped item in a container;
• and
• (c) closing the container to maximize the corrosion inhibiting effects of the vapor phase compound produced and released therein.
