The present disclosure relates generally to storing used cooking oil, grease, and fat, and more specifically storing them in a disposable bag housed in a secured container
Used edible cooking oil is currently stored in make-shift containers originally designed for other purposes, or simply poured down the drain or into garbage bags. When these improvised containers are discarded, the material and unsecured oil negatively impact the environment. Home cooks who pour used oil down the drain often are unaware of the damage done to pipes, which leads to clogged drains and countless plumbing bills. Pouring these excess oils, greases, and fats down the drain, toilet or outside end up contaminating water systems and sources. When pouring these materials down a drain, the oils, greases, and fats lead to developing “fatbergs” that may lead to extremely costly plumbing repairs. The oils, greases and fats that enter water bodies this way may form a surface film in the water, blocking oxygen and sunlight, harming aquatic life by impeding plant growth and endangering aquatic creatures. Additionally, the practice of pouring the used cooking oil into the rest of one's garbage is the most dangerous because this action is a leading factor in grease fires.
Accordingly, it is an object of one or more embodiments of the present disclosure to provide a disposable bag into which used oil, grease, and fat is poured, and a plant-based solidifying blend is placed, causing the oil, grease, and fat to solidify.
It is a further object of one or more embodiments of the disclosure to provide a container, with a handle, lid, and slots, configured to hold the disposable bag.
It is a further object of one or more embodiments of the disclosure for the plant-based solidifier blend to oversaturate used oil, grease, and fat with hydrogen, increasing the melting point, resulting in the oil, grease, and fat being a solid at room temperature, making it much more manageable to contain.
Other objects will appear hereinafter.
The above and other objects of the present disclosure may be accomplished with a device for storing used oil, grease, and fat. The device includes a disposable bag, where used oil grease, and fat is poured, and into which a plant-based solidifying blend is placed. The device also includes a container, including a handle, lid, and slots, configured to hold the bag that fits inside the container. The plant-based solidifying blend causes the oil, grease, and fat to solidify after coming into contact with one another.
The objects of the disclosure are further achieved by the plant-based solidifying blend comprising a tablet or flakes placed inside, or a paste or spray on material placed on the inner lining, of the bag.
The object of this disclosure includes its variants, and its alternative embodiments, independently of its applications or processes it may be applied to.
The present disclosure will be more clearly understood from the following description taken in conjunction with the accompanying drawings in which like reference numerals designate similar or corresponding elements, regions, and portions and in which:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
