Abstract

A deodorizer in particular, a deodorizer substrate with a porous carrier material formed in a monolithic form, and an odor neutralizing composition in the porous carrier material.

Claims (17)

1. An odor deodorizer, comprising:

I) a disk-shaped, monolithic porous carrier material of microporous high density polyethylene, having pores in the range of 45-100 microns;

ii) an odor neutralizing composition of undecylenic acid and/or a derivative thereof in the porous carrier material; and

iii) a disk-shaped housing made of talc filled, injection-moldable polypropylene sized to fit in a shoe and having a plurality of holes and containing the porous carrier, the housing being movable between an open to a closed configuration.

2. An odor deodorizer comprising:

i) a porous carrier material formed in a monolithic form;

ii) an odor neutralizing composition in the porous carrier material; and

iii) a housing containing a plurality of holes, the housing containing the porous carrier, wherein the material of the housing is a talc filled, injection-molded polypropylene material.

3. The odor deodorizer of claim 2 wherein the housing further comprises at least one sheath configured to cover at least a subset of the plurality of holes.

4. The odor deodorizer of claim 3 wherein the sheath is movably connected to the housing and movable from a closed position to an open position.

5. The odor deodorizer of claim 2 wherein the number of the holes is up to 50.

6. The odor deodorizer of claim 2 wherein the number of the holes is up to 42.

7. The odor deodorizer of claim 2 wherein the size of the holes is up to 3.0 mm in diameter.

8. The odor deodorizer of claim 2 wherein the size of the holes is up to 2.0 mm in diameter.

9. An article of manufacture, comprising:

a shoe deodorizer substrate containing an effective amount of an undecylenic acid and or a derivative thereof in a porous monolithic carrier; and

a sealed package formed at least in part of a heat sealing, low organic vapor transport packaging film, the package containing the shoe deodorizer substrate, wherein the sealed package further comprises a sealed inner layer of polyethylene terephthalate located inside the packaging film and surrounding the shoe deodorizer substrate.
