DETAILED DESCRIPTION

[0028] A device for holding solidified oils, greases, and fats is disclosed. The device comprises a disposable bag fitted inside a heat resistant container, where the bag holds used oil, grease, and fat, as it is poured into it. The bag is designed to fit inside the container and may include a bulb at its bottom, which fits inside the container, to help keep the bag in place during use. An airtight cover is attached to the top of the container to prevent spills. A solidifying agent, in tablet or flake or spray on material or paste form, is placed inside the bag, causing the used oil, grease, and fat to solidify. The container design comprises two slots for a tin tie to rest in, and to hold the bag securely. The disclosure described herein provides a safe, convenient way to dispose of used cooking oil.

[0029] The key features of the design include a plant-based solidifying blend placed inside the bag or on its inner lining. The heat-resistant container includes a main container and a cover, preferably made from recycled PET plastic. A flared container top is used to better funnel liquids into the container. A simple thread on/off sealing process is implemented with the airtight cover and includes an extended bottom portion that dips into the main container when fully on, to prevent internal spillage. The dual layered bag may be made from jute burlap and wax/parchment paper stitched together with thread. At the top of the bag, a tin-tie may be stitched or glued, for closing and securing the contents of the bag. Other methods of attaching the jute burlap to the wax/parchment include an adhesive spray/gel such as a water based adhesive spray, beeswax, or gum rosin, or a non-toxic adhesive such as a non-toxic glue. Other materials for the bag construction include natural fibers such as bamboo or hemp, or grease paper, sticky on one side and non-sticky on the other, with a thickness of, for example, at least 30 GSM. Other methods of closing the bag include cloth drawstrings.

[0030] Materials for the plant-based solidifying agent may comprise stearic acid and oleic acid in a 4:1 ratio. The materials may also include, for example, 4 tablespoons of stearic acid, 2 tablespoons of oleic acid, and 1 tablespoon of beeswax, where the beeswax adds elasticity, a paste-like texture, malleability, and a pleasant scent to the bag and its contents.

[0031] FIG. 1A illustrates, in a perspective view, container 100, handle 110, and lid 130, in a first preferred embodiment of the present disclosure.

[0032] FIG. 1B shows, in a perspective view, bag 120, into which the used oil is poured. The bag is designed to fit inside the container, including bulb 140 at its bottom, to help keep the bag in place during use.

[0033] FIG. 1C illustrates, in a perspective view, bag 120 fitting inside container 100, which is covered with lid 130, that attaches to the top of the container.

[0034] The main container is preferably made of 100% recycled polyethylene (rPET) plastic to ensure it does not negatively impact the environment. rPet is a food-safe raw material made from empty PET packaging that has been collected and prepared for recycling. rPET has on average a melting point of 243 degrees Celsius and can withstand high temperatures. It is commonly used for food containers with the anticipation for storing hot and cold foods and is one of the best plastics regarding stability over a wide range of temperatures. Other possible container materials include carbon, chosen for its heat-resilient properties and carbon negative emissions.

[0035] FIGS. 2A, 2B, and 2C depict a second preferred embodiment, showing the container 100 with the lid 130 screwed off, from a top view. The container has an airtight, threaded top 150 onto which the lid is screwed, to help prevent the escape of unwanted odors from the used oil, grease, and fat inside the container. The lid is configured with an extended bottom portion that dips into the container when the lid is fully attached and may include an O-ring for an airtight seal. The container design includes slots 195 for a tin tie to rest in and hold the bag securely.

[0036] FIGS. 2D and 2E illustrate the container 100 with the lid 130 screwed on, from the top and the side, for the second preferred embodiment. The container has a strong ergonomic handle 110, with a mug like design. The materials used in the construction can withstand high temperatures allowing a consumer to immediately pour hot used oil into the bag held by the container, eliminating wait time for cleanup.

[0037] FIG. 3A shows the container 100, with its lid 130, handle 110, and bag 120 separately and assembled, in a side view of the second preferred embodiment. The bag is preferably made from natural fiber material making it biodegradable, allowing a consumer the option to compost the bag along with its contents.

[0038] FIG. 3B illustrates a bottom view of container 100, in the second preferred embodiment.

[0039] The bag may comprise a closing system of plastic tin ties, preferably about 5/32 inch by 7 inches in size, to allow for a secure sealing method. FIG. 4A shows tin tie 190 attached to bag 120 with an adhesive, at a height 191 of, for example, 5/64 inch from the top of the bag. FIG. 4B shows the tin tie sewn onto the top of bag with thread 180, for extra security. The tin tie may fold upon itself, leaving a space 192 of, for example, a little more than 25/64 inch.

[0040] FIG. 4C shows the end of the tin tie before being bent on itself, at a length 193 of, for example, inch. FIG. 4D shows the end of the tin tie after being bent on itself, at a length 194 of, for example, inch. In this way, the tin tie may bend at the end to lock into position.

[0041] FIG. 4E illustrates how tin tie 190 is placed so that the consumer can fold the top of bag 120 over itself, and unwanted excess heating oil may be disposed of without spills. Also, the tin tie can easily be removed if the consumer wants to compost the bag without it.

[0042] FIG. 5A shows the composition of the bag may be a double layer of burlap 160 and wax/parchment paper 170, in a top view. The dual layer prevents the contents inside the bag from spilling out or leaking through. The diameter 196 of the bag may be, for example, 4.25 inches across. FIG. 5B shows a disposable and compostable natural fiber bag, comprised of jute burlap lined with wax/parchment paper, sewn together with thread 180. The size of the stitch 197 may be, for example, 25/64 inch. The total height of the bag is preferably 4 23/32 inches, and other heights may be used.

[0043] The bag may typically store up to 16 oz of used edible oils, greases, and fats. The bag may be treated with a vinegar solution sprayed on the outside of the bag. The vinegar solution may comprise white vinegar and an essential oil, such as jasmine or other scents. This inhibits mold growth and helps to control odor. Advantages of the jute burlap or natural fibers include the burlap being a natural fiber, breathable, and able to withstand high temperatures needed for the used cooking oil. Mainly edible oils, such as greases and animal fats, are meant to be stored in the bag.

[0044] The plant-based solidifying blend may be in tablet or flake form, placed at the bottom of the bag. The solidifying agent may also comprise a paste or spray on material placed on the inner lining of the bag up to a height of, for example, 2.16 inches. The heat of the oil melts the tablet or paste and starts the solidifying process. The composition of the solidifying blend oversaturates the oils, greases, and fats with hydrogen, increasing their melting point, resulting in a material that is solid at room temperature. This makes the contents of the bag much more manageable to contain. The ingredients used in the tablet may, for example, comprise stearic acid and oleic acid in a 4:1 ratio, where the stearic acid acts as a solidifying agent for most edible oils, while still being food-grade for people of all religions and cultures.

[0045] Ratios for the solidifying agent may vary within limits, for example, 1 to 8 tablespoons of Stearic Acid, 1 to 8 tablespoons of Oleic Acid, and 1 to 4 tablespoons of Beeswax. Note that different ratios may affect the quality of the solidifying process.

[0046] The advantages of one or more embodiments of the present disclosure include providing a disposable bag inside which an oil solidifying blend is placed. The bag is housed in a secure container and made from environmentally friendly materials. The container is made from 100% recycled plastic and is heat resistant. The container is flared for safety and covered with a lid. The device for storing used oil, grease, and fat is for anyone who cooks on a regular basis and provides for quick and easy cleanup. The disclosure prevents unsafe oil disposal, and protects from leaks, spills, and grease fires. The disclosure prevents oils, greases and fats from entering water bodies and forming a surface film in the water, blocking oxygen and sunlight, harming aquatic life.

[0047] While particular embodiments of the present disclosure have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made without departing from the spirit and scope of the invention.
