Description
Cooking Oil Receptacle
Technical Field The invention relates to receptacles for spent cooking oil, particularly oil used domestically and commercially for the preparation and storage of foodstuffs.
Background to the Invention
Spent oil and fat are frequent by-products of many activities associated with the preparation and storage of foodstuffs, such as the preserving, frying, roasting and grilling of foods. The safe disposal of spent or used oil and fat presents problems in the kitchen. One option is to dispose of spent oils and fats in the sink but this can often lead to problems of sink blockage when the hot oils and fats come into contact with cold water and/or surfaces.
Another solution to this problem is to transfer the oil or fat into a suitable container and then discard the container as waste. Unfortunately relatively few containers available in the kitchen are suitable for this purpose. Those containers which are available tend to have narrow apertures or openings which make transfer of the oil difficult and can result in spillage. A further problem with many existing containers is that they are composed of plastics which may be dissolved by the oil leading to leakage from the container. This problem is exacerbated by pouring hot oil directly from a frying or cooking pan into plastic bottles which are not resistant to oil, especially hot oil. Glass bottles and containers also pose problems in terms of user safety as the glass may break on pouring the hot oil or on subsequent disposal of the container. Nor are metallic containers, such as used can or foil containers, particularly suitable for disposal of oil as they are seldom reclosable and may present handling hazards due to their sharp, ragged edges.
Materials are known in the art which can be used to absorb oil. Thus U. S. Patent Number 6, 092, 302 describes a cellulosic based fibre granule which has a high oil absorptive capacity. U. S. patent number 5,700, 558 also discloses the use of cellulose based materials for cleaning oil spillages which occur in field and industrial operations. Other naturally occurring plant products, such as those based upon bagasse and cottonseed lint, have high oil absorptive capacities and can be used to clean oil spillages (U. S. Patent Number 5,554, 575).
Although such materials exist, no one has previously addressed the problem of using these or related materials to dispose of cooking oil waste products in the kitchen. It is an object of the present invention to provide a receptacle for spent cooking oils which can be used in a domestic or commercial kitchen environment and which can be easily disposed of thereafter.
Summary of Invention
According to one aspect of the present invention there is a receptacle for spent cooking oil comprising an oil impermeable casing; an aperture within said casing enabling access thereto; and an oil absorbent matrix within the casing. In the context of the present invention, absorption should be construed to include processes with are both absorptive and adsorptive in nature.
In one aspect, the receptacle additionally comprises an oil impermeable layer with perforations therein between the aperture and the matrix.
In another aspect, the matrix comprises an oil absorbent sponge material.
Preferably the sponge material additionally comprises a water absorbent material.

A A A
Preferably the pad additionally comprises a water absorbent material.
In one aspect, the pad comprises layers of oil absorbent and water absorbent materials.
In another aspect, the matrix comprises beads of oil absorbent material. Suitable beads or granules are described in U. S. Patent Number 6,092, 302. The granules are comprised of 10 to 99 weight percent self associating, cellulosic, plant fibres and from 1 to 90 weight percent of particulate materials with an aspect ratio of less than 3. The particulates are non-film forming or non-self associating, insoluble and inorganic or organic in nature. However, the total percent of inorganic particulate materials in the granules should be from 25-36 percent by weight of the granules.
The particulates have an average diameter of from 2 to 250 microns or micrometers, preferably 5 to 200 micrometers. The total amount of inorganic material in the granule should be less than 36% by weight of the granule, to enable incineration after use.
Preferably the matrix additionally comprises beads of water absorbent material.
In a further aspect, the matrix comprises fibres of oil absorbent material. U. S. Patent
Number 6,092, 302 also discloses fibres comprising non-self associating inorganic or organic fibres mixed with self associating cellulosic plant fibres. These fibres have an aspect ratio of greater than 3 and an average diameter of from 0.1 to 100 micrometers, preferably greater than 1 micrometer. The total amount of inorganic materials should be less than 36 percent by weight to enable incineration after use and minimise the production of ash.
Preferably the matrix additionally comprises fibres of water absorbent material.
In one aspect, the matrix is biodegradable. U. S. Patent Number 5,554, 575 discloses a biodegradable oil. absorbent material formulated from natural fibres comprised of processed bagasse and cottonseed hull lint. It further includes mineral oil that can serve both as a dust suppressant and a binder. Typically, the proportions of these ingredients, by weight, would be about 75% bagasse, about 25% cottonseed hull lint,
and less than 0. 1% mineral oil. The bagasse is collected and dried to reduce the moisture content to typically less than 12%, and ideally around 8%. The dried bagasse is combined proportionately with cottonseed hull lint and then chopped and ground through a milling process to produce the desired grind. This material is then inoculated with microbial strains capable of consuming hydrocarbons, such as petroleum, using overhead spray equipment. Such microbes will remain in a dormant, inactive state until they are activated by the introduction of some catalysing agent. A suitable catalysing agent could be water, used after the mixture has absorbed some hydrocarbon contaminant. The microbes normally require oxygen, food (hydrocarbons), sustained moisture on the order or 30%, and suitable temperature (in the range of 35-130 degrees F. ) to become activated. After they are activated, the microbes will consume the hydrocarbon wastes at a variable rate as long as the conditions above are present. Mineral oil is then also added as a dust inhibitor to the compound with similar overhead spray equipment. The mineral oil may also serve as a binder to ensure that the coarser bagasse portion and finer cottonseed hull lint portion remain uniformly mixed.
Preferably the matrix comprises a chemical to absorb malodorous volatiles. More preferably the matrix comprises a deodorising chemical. Suitable deodorising chemicals include jasmine oils, citrus oils (e. g. lemon or lime oils) and terpenoid derivatives.
In another aspect, the matrix comprises an oil degrading microorganism. Suitable microrganisms are well known in the art and may, for example, be obtained from
Advanced BioTech Inc., California, USA.
In one aspect, the casing comprises an oil resistant plastic. Preferably the plastic is heat resistant.
In another aspect, the plastic is selected from the group consisting of polyethylene, polyvinyl chloride, polybenzimidazole, polycarbonate, polyester, polyterephthalate, polyimide, polyacrylamide, polyacetal, polyurethane and polyacrylonitrile.
Preferably the plastic is biodegradable.
In one aspect, the casing comprises cardboard treated with an oil impermeable chemical.
In another aspect, the receptacle additionally comprises a window in the casing to view the level of oil in the matrix. The window may be located in the top or side of the casing. Preferably the matrix additionally comprises a dye to aid visualising the level of oil in the matrix. Suitable dyes which change colour on mixing with oils are well known in the art and may, for example, be obtained from Sandy Brae
Laboratories, Delaware, USA.
In a further aspect, the aperture comprises a funnel to facilitate pouring of oil into the receptacle.
In one aspect, the receptacle additionally comprises a lid to seal the aperture.
Preferably the lid is reclosable to reseal the aperture. More preferably the lid is resealable by adhesive means. The adhesive should be resistant to oil.
Preferably the lid is resealable by a snap fit mechanism. More preferably the lid is resealable by a hinged mechanism. Most preferably the lid is resealable by a spring mechanism.

Detailed Description of Drawings
Figure 1 is a cross-sectional view of a receptacle according to the present invention.
The receptacle 10 comprises oil absorbent matrix 20 in the form of a pad which and is enclosed within an oil impermeable casing 30 composed of a rigid plastic.
Reclosable lid 40 may be opened to give access to aperture 50 for pouring spent or used cooking oil into the receptacle. The mouth of the aperture 50 is funnel shaped 55 to facilitate pouring of oil into the receptacle. Transparent window 60, composed of a suitable plastic, can be used to view when the receptacle 10 is full of oil. The lid 40 may be closed to prevent malodorous smells escaping from the receptacle 10.
Figure 2 is another cross-sectional view of a variant of the present invention. The matrix 120 is composed of layers of oil absorbent 122 and water absorbent 124 materials. Spent cooking oil 170 is poured onto the matrix 120 through aperture 150, which is funnel shaped 155, and is absorbed by the oil absorbent layers 122
within matrix 120. Any water within the spent oil (for example from the cooking process) is trapped within the water absorbent layers 124.
Figure 3 shows another cross-sectional variant of the present invention. The matrix 220 is composed of beads 224 of oil absorbent material and is covered by a perforated layer of oil impermeable material 226, such as a plastic. Spent cooking oil 270 poured through aperture 250 percolates through the perforations 227 in layer 226 to be absorbed by beads 224. The layer 226 prevents loss and/or decanting of the beads 224 on movement of the receptacle 210. Layer 226 also assists in spreading the oil 270 uniformly across the surface of the matrix 220.
Figures 4a and b show side perspectives of a variant of the present invention. The matrix 320 is enclosed in a flexible plastic 330 casing or film wrapper (Figure 4a).
Reclosable lid 340 may be opened (Figure 4b) to allow pouring of spent oil into the matrix 320 through funnel shaped 355 aperture 350. The periphery of lid 340 is coated with a suitable oil resistant adhesive 342 which permits resealing on filling of the receptacle 310. Window 360 can be used to determine when the level of oil within the receptacle 310 is full. The dimensions of receptacle 310 are such that it may be used for the disposal of a small volume (less than 100 ml) of oil only before it is discarded.
Figures 5a & 5b shows a side perspective of a variant of the present invention suitable for retaining large volumes (greater than 100 ml) of spent cooking oil. A rigid plastic casing 430 encloses matrix 420 composed of an oil absorbent material (Figure 5a). The lid 440 of receptacle 410 is hinged 441 and may be opened to permit pouring of oil (not shown) onto matrix 420 through funnel shaped 455 aperture 450 (Figure 5b). The level of oil within the receptacle may be read through transparent window 460. An indicator dye, which changes colour on mixture with oil, may be added to the matrix 420 to facilitate reading the level of oil within the receptacle 410.
It will be understood that the present disclosure is for the purpose of illustration only and the invention extends to modifications, variations and improvements thereto.
