Abstract

The filter consists of layers 1 of activated carbon impregnated substrate, covered in a fibrous material 3 which itself is treated with deodorisers. The filter is designed to be placed in close proximity to the anus and in the event of a passage of wind the activated carbon by virtue of its very high surface area will absorb the malodorous gases into its porous structure. The filter is made from layers of the substrate each layer with a thickness of between 0.5mm and 50mm and each layer having a surface weight of between 50g/m2 and 1000g/m2. Each layer of the substrate will have been impregnated with between 10g/m2 and 300g/m2 of activated carbon.

Description

Title FLATULENCE ODOUR REMOVING FILTER Technical Field THIS INVENTION RELATES TO A FLATULENCE ODOUR REMOVING FILTER Background Many inventions and much research have been concentrated on the control of bad smells generated by human bodily fluids or vapours created from these fluids such as urine Menstrual fluid and perspiration. No invention has yet been designed to control the malodorous gases created by flatulence and everyday excess gas discharge from the bowels.

Broad Description According to the invention a filter consists of at least one layer of activated carbon impregnated substrate covered with a fibrous material which is coated with deodorisers.

The filter is designed to be placed in close proximity to the anus and in the event of a passage of wind the activated carbon by virtue of its very high surface area will absorb the malodorous gases into its porous structure, thus giving the user and other persons within the vicinity, relief from the unpleasant smells normally associated therewith.

Detailed Description The Filter is made up from between one and ten different layers of the substrate each layer with a thickness of between 0.5mm and 50mm and each layer having a surface weight of between 50g/m2 and 1000g/m2. Each layer will also have been impregnated with between iOg/m2 and 300g/m2 of activated carbon. The layers of activated carbon substrate are alternated and then covered with the fibrous material which itself has been coated with deodorisers. The fibrous material being of the type used in sanitary towels and coated with deodorizer synthetic zeolite.The size and shape of the filter can be varied to suit different size people and methods of proximity to the anus other than attaching the filter to underwear, for instance a large filter can be produced designed to be placed of the seat of a car, domestic chair or bedding.

Example 1 In this example a description of a light duty dual layer filter is explained.

See diagram A.

1. shows two layers of activated carbon impregnated substrate 1 mm thick each and each containing 90g/m2 of activated carbon.

2. shows a layer of nonwoven deodorised material and 3 shows the same material as 2. used as a cover for the 3 layers.

4. shows the overall shape which would be cut to fit an average crotch section of an undergarment. This filter is designed to be placed inside the undergarment and attatched by means of a self adhesive sticky strip protected by a peel off protective strip 5.

FLATULENCE ODOUR REMOVING FILTER Example 2.

In this example a description of a heavy duty single layer filter is explained See Diagram B.

1. shows a single layer 1 Omm thick nonwoven impregnated with 150g/m2 of activated carbon 2. shows the deodorized paper cover used to wrap the substrate.

3. shows the overall shape of the filter cut to fit the average crotch section of an undergarment to be attached by 4. A self adhesive sticky strip protected by a peel off cover.

Example 3.

In this example a description of a large dual layer filter is expalined See diagram C.

1. shows the 2 layers of activated carbon substrate each being 1 Omm thick and having a carbon content of iSOg/m2 2. shows a layer of polyester fabric used to cover the filter. 3.

shows the square shape of the filter cut to be used on the seat of a car or domestic chair or a bed.

Example 4.

In this example a single layer filter is explained of the type designed to be used as a fabric for making underwear or as a removable crotch section for use with undergarments designed to receive detachable crotch sections.

See Diagram D.

1. Shows a single layer of activated carbon substrate 1 mm thick and impregnated with 1 20g/m2 of the carbon and 2. shows the deodorized paper cover used to wrap the substrate.

3. shows the shape designed for a removable crotch section undergarment and 4. shows the roll of filter produced for use by undergarment makers, the makers would cut the filter to suit the type of undergarment being made to benefit from the malodorous gas removing quality afforded by the filter.

Claims

1. A filter with layers of activated carbon substrate which removes the smell of malodorous gases passed from the bowel through the anal passage.
