The present invention relates to a reusable food or beverage container used as a part of a commercial reusable container system that is easily washed using minimal resources. In particular, the present invention relates to a container with at least one self-cleaning surface, the reusable container further including an identification device to identify the reusable container as a part of a reusable container system.
There is a growing trend to reduce or eliminate single-use coffee cups. Reusable cup programs have emerged as an alternative to single-use cups, but require extensive resources and logistics to collect and clean the reusable cups prior to being used again. Additionally, because the process of collecting, cleaning, and restocking the reusable cups often takes 24 hours or more, the reusable cup program requires multiples of excess quantities of cups beyond the quantity of users of the program to account for the cups being out of circulation at any given time. Coffee shops and cafes often allow customers to bring in their own reusable coffee cups or travel mugs. This trend has a positive impact on reducing the total number of single-use or reusable cups used. Unfortunately, proper cleaning and sanitizing of these reusable cups in such a way that they are safe to be handled and filled by the baristas or servers requires extensive resources. Additionally, the time and effort required to properly clean and sanitize the cups often prevents users from choosing to bring their own reusable containers. Incentives, such as discounts on drinks, are often used to encourage customers to bring their own reusable cups. However, these incentives are often not enough to overcome the perceived inconvenience by customers, such as not being able to order prior to arrival or making use of automatic payments using a mobile application.
While prior systems have focused on the tracking the deployment, receipt, and washing of such re-usable containers within the system, these systems have not focused on making the reusable container itself easier or more convenient to wash and use by a user.
There is a need for a reusable food or beverage container that requires minimal resources to appropriately rinse and sanitize prior to reuse. In order to incentivize the use of such containers, the containers include an identification device particularly configured to enable identification of the specific reusable container as a part of a reusable container system. Identifying the specific reusable container that is being used can trigger automated events, such as automatic ordering, automatic payments, priority service, applying discounts and other incentives, and customer loyalty rewards. The identification device can also be used to enable the reusable container to be used with accompanying devices of the reusable container system, such as allowing the container to be inserted into an automated washing system or sanitizing system. The settings of such systems can also be customized based on known information about the particular reusable container identified, such as customizing wash settings based on the last known contents of the reusable container as well as the type, size, and material of the container.
In accordance with an embodiment of the present invention, a reusable food or beverage container with at least one self-cleaning surface and an identification device is provided. The at least one self-cleaning surface of the reusable food or beverage container enables effective cleaning of the surface using minimal effort and resources, such as completely evacuating all contents when poured out, easily rinsing away residue using only water, or other cleaning and sanitizing methods using minimal effort and resources. The self-cleaning characteristics of the at least one surface also make the reusable food or beverage container easier to dry after rinsing or washing, as the water is effectively removed from the surface using only the force of gravity or with minimal effort such as spinning, shaking, or drying with a cloth. The identification device attached to or embedded in the reusable food or beverage container identifies the container as a part of a reusable container system. By reading the identification device of the reusable food or beverage container, the reusable container system can track the use of reusable food or beverage container, as well as automate systems associated with the container, such as automatic ordering, payments, and discounts.
In accordance with aspects of the present invention, a reusable food or beverage container includes a bottom, at least one side-wall extending from the bottom to define an interior volume and an upper opening at the opposite end of the at least one side-wall from the bottom, and an identification device incorporated into and associated with the reusable food or beverage container.

In some aspects, the surfaces of the removable lid of the reusable food or beverage container are self-cleaning. In some aspects, a portion of the surfaces of the removable lid of the reusable food or beverage container is self-cleaning.
In accordance with aspects of the present invention, the identification device of the reusable food or beverage container includes one or more of a bar code, a quick response (QR) code, a near-field communication (NFC) chip, a radio-frequency identification (RFID) tag, or a unique visual marking.
In accordance with aspects of the present invention, the identification device of the reusable food or beverage container associates the reusable food or beverage container with a data store containing information and preferences related to the reusable food or beverage container. In some aspects, the data store contains information to initiate automated processes associated with the reusable food or beverage container. In some aspects, the data store contains information to set parameters of the automated processes associated with the reusable food or beverage container.
In accordance with aspects of the present invention, the self-cleaning surface comprises a superhydrophobic surface. In other aspects, the self-cleaning surface comprises a superoleophobic surface. In still other aspects, the self-cleaning surface comprises a superhydrophilic surface. In further aspects, the self-cleaning surface comprises a photocatalytic surface.
In accordance with aspects of the present invention, the identification device incorporated into and associated with said reusable food or beverage container is disposed in the bottom of the reusable food or beverage container.

In accordance with aspects of the present invention, the reusable food or beverage container comprises a cup. In other aspects, the reusable food or beverage container comprises a take-out food container.
These and other characteristics of the present invention will be more fully understood by reference to the following detailed description in conjunction with the attached drawings, in which:
Illustrative embodiments of the present invention relate to a reusable food or beverage container with a self-cleaning surface and identification device. The identification device of the reusable food or beverage container identifies the reusable food or beverage container as a part of a reusable container system used by a business or institution, such as a coffee shop, to promote and track the use of reusable containers, such as reusable coffee cups. The reusable food or beverage container features at least one surface with self-cleaning characteristics such that the container is efficiently and effectively cleaned and sanitized using minimal effort, time, and resources. The reusable food or beverage container with a self-cleaning surface and identification device provides a simple, efficient, and easy-to-use replacement for the prevalent use of single-use containers and the associated disposal waste and other environmental issues. Additionally, the reusable food or beverage container with self-cleaning surface and identification device provides a more environmentally friendly alternative to existing reusable containers and systems that require extensive resources for washing, and an excess number of reusable containers to account for reusable containers out of circulation during the washing process.
In the example illustration, the reusable container 100 is in the form of a reusable coffee cup and as such has dimensions that can vary but are generally about 2.25 inches to 2.5 inches for the small diameter, about 3 inches to 3.75 inches for the large diameter, and between about 3.25 inches to about 8 inches of height, for containers with an interior volume 106 capacity range from approximately 6 fluid ounces to 22 fluid ounces. Those of skill in the art will appreciate that these dimensions are approximate and are intended to describe the approximate size and shape of conventional coffee cups, or the like, which conventionally fit in conventional automobile cup holders, and can be found in numerous coffee retail stores. Furthermore, those of skill in the art will appreciate the dimensional attributes are provided for enablement purposes only as it relates to a reusable container 100 for coffee or similar beverage or the like, and can be altered or varied to accommodate different containers of different dimensions for different purposes, and are therefore not limiting of the scope of the invention.
Continuing with
A self-cleaning surface as utilized herein refers to a class of materials with the inherent ability for liquids, debris, bacteria, and the like to be easily removed or repelled, such as sliding or rolling off from the force of gravity, or rinsed off with water (See the Wikipedia entry for “Self-cleaning surfaces” as of November, 2022 at https://en.wikipedia.org/wiki/Self-cleaning_surfaces#:˜text=Self%2Dcleaning%20surfaces%20are%20a.striders%20to%20na me%20a%20few).
One common type of self-cleaning surface is superhydrophobic, which is a general term for a surface that resists water adhering to the surface, such that the water beads and easily rolls off.
Another measurable characteristic of superhydrophobic surfaces is a roll-off angle (θR).
Superhydrophobic surfaces are just one example structure and method of creating a self-cleaning surface, but such a surface may only be effective in easily removing water-based liquids from the surface. Various other surface characteristics, or combinations of surface characteristics, can be used to optimize the self-cleaning ability of the surface for a particular type of fluid or debris to be repelled, such as superoleophobic surfaces to repel oil-based liquids or low friction surfaces designed to allow yield-stress fluids, such as gels, to easily slide across the surface.
For self-cleaning surfaces that require debris and bacteria to easily be removed, superhydrophilic surfaces can be used.
Creating an effective self-cleaning surface is a combination of surface texture and surface chemistry. In accordance with aspects of the present invention, the self-cleaning surface can be optimized for the particular contents or a general class of contents that are to be contained within the reusable container 100 (refer to
The self-cleaning surface can be the surface of the material of the reusable container 100 itself, such as a superhydrophobic polymer. In another example embodiment, the self-cleaning surface can be an additional material impregnated into the material of the reusable container 100, such as a liquid-impregnated coating saturated into the polymer of the reusable container 100. In yet another example embodiment, the self-cleaning surface can be a coating, such as a spray-on coating applied to the surface of the reusable container 100. These and other structures and methods for creating a self-cleaning surface on a reusable container 100, as appreciated by one of skill in the art, are considered to fall within the spirit and scope of the present invention.
The material of the bottom 102 and at least one side-wall 104 of the reusable container 100 can be any of such material or combination of materials operable for reusable food and beverage containers in accordance with the requirements of the present invention, such as, but not limited to, plastics (polypropylene (PP), polyethylene (PE), acrylonitrile butadiene styrene (ABS), polyetheretherketone (PEEK), and the like), metals (stainless steel, copper, aluminum, titanium, and the like), glass, natural fibers (bamboo, corn husks, and the like) or other such suitable materials. The reusable container 100 can be comprised of one material, such as a single-walled beverage cup or double-walled beverage cup in which the material comprising the inner wall and the outer wall are the same. In an example embodiment, the double-walled reusable container can be comprised of multiple materials, such as stainless steel for the material that comprises the inner wall, and polypropylene for the material that comprises the outer wall. Materials comprising the inner and outer walls of a double-walled reusable container, whether the same material or different materials, can be positioned in close proximity, such as bonded together. In an example embodiment, the inner and outer walls can be spaced apart, such as by an air gap or vacuum chamber between them, as found on thermally insulated reusable food and beverage containers as would be appreciated by one of skill in the art. In an example embodiment, additional materials can be used to enhance the usability or functionality of the reusable container 100, such as an exterior sleeve made of a low heat transfer material (wood, natural fibers, and the like) to protect the hand of a person carrying the reusable container 100 filled with hot contents, or a non-marking bottom pad (rubber, cork, or the like) on the bottom 102 to prevent the reusable container 100 from marking surfaces on to which it is placed.
The materials and chemistries used as additives or coatings used to create a self-cleaning surface can be any of such materials and chemistries commonly used for such purposes. Although known materials and processes, such as polytetrafluoroethylene (PTFE) or copper, can be used to create a self-cleaning surface, many materials, chemistries, and related processes for blending, impregnating, and coating are proprietary, such as, but not limited to, the proprietary technology of Aculon, Chempilots, Nanoslic, SilcoTek, NeverWet, LiquiGlide, and the like, all of which are commercially available. One of skill in the art will appreciate that additives, coatings, chemicals, materials, and design of surface textures can be optimized for a particular use, such as the self-cleaning parameters and durability required for a reusable coffee cup of the present example. One of skill in the art will further appreciate the effective life of self-cleaning surfaces for the present example can be enhanced by the periodic addition of energy, such as by exposure to UV light or heat, such as from the washing process or from the hot beverage or other hot contents of the reusable container 100, to cause a temporary chemical reaction or a particular component to bloom to the surface. Since the contents of the present example reusable coffee cup are intended for human consumption, such as coffee, tea, milk, and the like, the additives, coatings, chemicals, and materials that will come into contact with the contents must be approved for such use by the United States Food and Drug Administration (FDA), or other such equivalent regional or local agency.
At a point of receipt, the identification device 140 is read by a reader 302 of the reusable container system 300 to track the use of the reusable container 100 associated with that identification device 140. In an example embodiment, the reader 302 can initiate or trigger automated events or processes associated with the identification device 140 read, such as but not limited to automatic ordering, automatic payments, priority service, and applying discounts, incentives, and customer loyalty rewards as would be appreciated by one of skill in the art. In an example embodiment, the automated event can be a marking process of the reusable container 100, such as information about the beverage to be contained in the reusable container 100, by printing such information on the reusable container 100 itself, or by printing a label containing such information to be applied, either automatically or manually, to the reusable container 100 as would be appreciated by one of skill in the art.
In an example embodiment of the present invention, the reader 302 can be a part of, or in communication with, other devices of the reusable container system 300, such as enabling the reusable container 100 to be inserted into additional devices of the reusable container system 300, such as automated collection bins, washing systems, and sanitizing systems, such as by ultraviolet (UV) light or the like. In an example embodiment, the settings of the devices of the reusable container system 300 can be optimized based on information related to the reusable container 100 identified by the associated identification device 140, such as customizing the wash settings based on known information about the reusable container 100, such as size, shape, material, or last known contents.
