[0001] This application claims the benefit of U.S. Provisional Application Serial No. 63 / 691,533, titled “Modular Container Delivery System,” filed by Vijay Meduri, on September 6, 2024.

[0002] This application incorporates the entire contents of the foregoing application(s) herein by reference.TECHNICAL FIELD

[0003] Various embodiments relate generally to a food order and delivery system of tangible items.BACKGROUND

[0004] Food delivery has become a widely adopted solution for providing meals in institutional, corporate, and educational settings. For example, employees may receive lunch at office buildings, students at schools may rely on scheduled meal deliveries, and factory workers may depend on regular food drop-offs at centralized locations. This shift reflects both convenience and the growing preference for fresh, pre-arranged meal services that fit into structured daily routines.

[0005] Typically, these meals may, for example, be ordered in advance remotely (e.g., through a phone call). The delivery may be, for example, fulfilled through a logistics provider (e.g., a van or a delivery person hired by a catering service, food vendor) In some examples, the food may be distributed in batches to a communal pantry, a front desk, and / or a designated delivery rack.

[0006] In some cases, during the delivery process, food may become spoiled due to improper temperature maintenance and / or prolonged exposure to ambient conditions. When multiple meals arrive together, for example, multiple recipients may find it difficult to identify their specific orders (e.g., during a busy lunch time in an unsupervised environment).SUMMARY

[0007] Apparatus and associated methods relate to a portable food delivery container rack (PFDCR). In an illustrative example, a PFDCR includes a plurality of independently controlled portable food containers (ICPFC) operably connected to a control circuit. Each of the plurality of independently controlled portable food containers, for example, may include a food storage compartment encapsulated in an insulated thermal envelope. For example, the ICPFC may include an electronic lock independently controlled by the control circuit based on an access code received at a communication interface. For example, the access code may prevent illegitimate access to the ICPFC. For example, the PFDCR may operate with a portable power source in a low-battery mode.TPL Docket No.: 978-02-WO Various embodiments may advantageously prolong a continuous operation duration between each charge of the portable power source.

[0008] Apparatus and associated methods relate to modalized meal delivery and storage systems. In an illustrative example, an economical and modular delivery system (EFFMDS) may include modular controlled food containers (MCFC). The MCFC, for example, may be stackable on each other. Upon delivery, the MCFC are locked and may be individually unlocked by a predetermined access code specifically associated with each of the MCFC. In various embodiments, the MCFC may include an insulated thermal envelope. For example, the insulated thermal envelope may be configured to passively maintain a temperature of food stored within the MCFC. For example, the MCFC may be operated in a sleep mode until a person with the predetermined access code activates and retrieves the food in the MCFC. Various embodiments may advantageously converse energy in operating a temperature regulated and access-controlled container.

[0009] Various embodiments may achieve one or more advantages. For example, some embodiments may advantageously reduce floor space required for storing the fresh food delivered to the dining facility. Some embodiments may, for example, advantageously maintain a temperature of the stored fresh food within the fresh food compartment. For example, some embodiments may advantageously maintain a target fresh food temperature passively without being affected by active heat generating elements. Some embodiments may, for example, advantageously prevent food poisoning due to expired food. For example, some embodiments may last for at least six months without battery replacement. Some embodiments, for example, may advantageously reduce power consumption and extend battery life. For example, some embodiments may advantageously prevent the MCFC from being taken away from the rack illegitimately. Some embodiments may, for example, advantageously ensure that a person ordered the meal and / or an item receives the MCFC. For example, some embodiments may advantageously verify that a right person is taking the right food automatically.

[0010] The details of various embodiments are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 depicts an exemplary economical fresh food modular delivery system (EFFMDS) employed in an illustrative use-case scenario. In the depicted example, an EFFMDS 100 includes a fresh food container rack (FFCR 105) and a fresh food dispatch facility (FFDF 110). For example, the FFDF 110 may be configured to receive orders through a network 115 (e.g., the Internet, a cellular network, a Long Range Wide Area Network, a satellite internet). For example, the FFDF 110 may be configured to deliver ordered food to the FFCR 105 (e.g., via truck). For example, the ordered food may be delivered to a dining facility (e.g., a school canteen, an office pantry, a factory dining hall).

[0017] As shown, the EFFMDS 100 includes a mobile device 120. In this example, the mobile device 120 includes a fresh food order and retrieve app (FFORA 125). In this example, the mobile device 120 is connected to the FFDF 110. In one example depicted FIG. 1 , the FFORA 125 may be connected to the communication interface 150 via the network 115. For example, the communication interface 150 may include an internet protocol suite. As shown in FIG. 1, the mobile device 120 may also be configured to connect to the communication interface 150 directly. For example, the mobile device 120 may communicate with the communication interface 150 through a Bluetooth connection. For example, the mobile device 120 may communicate with the communication interface 150 through a near- field chip (NFC) connection. For example, the mobile device 120 may communicate with the communication interface 150 through a wireless connection (e.g., a Wireless Fidelity (WiFi) direct connection, an infrared connection). For example, a user may order food via the FFORA 125. In some implementations, the user may be an employee ordering for oneself for specific days. In some implementations, the user may be an administrator ordering for multiple people for multiple days.

[0018] The FFCR 105 includes modular controlled food container(s) (MCFC 130). For example, the MCFC 130 may include one or more individual containers. In some implementations, the FFCR 105 may be embodied in one or more standing racks (e.g., on wells, on a counter, on a table). For example, the standing racks may vertically (e.g., stackably) store the MCFC 130. Various embodiments may advantageously reduce floor space required for storing the fresh food delivered to the dining facility. For example, each of the MCFC 130 may include an insulated thermal envelope configured to receive and passively store a fresh meal for a predetermined period of time. For example, the MCFC 130 may be selectively lockable to the FFCR 105.TPL Docket No.: 978-02-WO |0019| The FFCR 105 may, for example, vertically store the MCFC 130 on a tabletop and / or a wheeled configuration (e.g., as shown in FIG. 1). Each individual food container may be lockable by an electronic lock 140. The electronic lock 140 may be openable by an access code. The electronic lock 140 may be powered by a battery 145 of the MCFC 130. For example, the electronic lock 140 may be armed when the fresh food is inserted at the FFDF 110. In some implementations, the FFDF 110 may associate an access code to unlock the electronic lock 140 with a specific end consumer. For example, the user may set the access code using the FFORA 125.

[0020] As shown, each MCFC 130 includes a communication interface 150 and a control module 155. For example, the communication interface 150 may be configured to receive input from the user. For example, the communication interface 150 may include a control interface. For example, the communication interface 150 may include a keypad. For example, the communication interface 150 may include a software interface configured to communicate with the mobile device 120 through the network 115. In some examples, the communication interface 150 may receive the user input from the FFORA 125.

[0021] The control module 155, for example, may control each of the MCFC 130. As an illustrative example, the control module 155 may unlock (e.g., activate) the electronic lock 140 of one of the MCFC 130 associated with a received access code. In some implementations, the communication interface 150 may include a screen on the activated one of the MCFC 130. In some examples, the screen may alert the user which of the MCFC 130 contains their food and is activated.

[0022] As an illustrative example, when the end consumer enters their unique access code (e.g., on the screen, through the FFORA 125), the electronic lock 140 may be opened and allow the user to access fresh food in a container (e.g., one of the MCFC 130) as described below with reference to FIG. 2.

[0023] FIG. 2 is a block diagram depicting an exemplary modular controlled food container (MCFC). In the depicted example, a MCFC 200 is connected to the mobile device 120 independently to the mobile device 120. For example, the FFORA 125 may transmit an access code to the MCFC 200. As shown, the MCFC 200 includes a fresh food compartment 205 encapsulated by an insulated thermal envelope 210. In some implementations, fresh food compartment 205 may be passively heated or cooled by the insulated thermal envelope 210. In some implementations, the insulated thermal envelope 210 may be manufactured without any active heating or cooling systems. For example, the insulated thermal envelope 210 may include one or more layers of thermal insulation material configured to minimize heat transfer between the fresh food compartment 205 and an external environment.TPL Docket No.: 978-02-WO 100241 The insulated thermal envelope 210, for example, may include vacuum insulation panels, expanded polystyrene (EPS) foam, and / or other suitable insulating materials that provide a high thermal resistance. Various embodiments may advantageously maintain a temperature of a stored fresh food 260 within the fresh food compartment 205 for an extended period of time while relying solely on the passive materials as described below.

[0025] As shown, the MCFC 200 includes a screen 215 and the electronic lock 140. In some implementations, the insulated thermal envelope 210 may, for example, exclude heat generating devices (e.g., a control board, power supply). For example, the communication interface 150 of FIG. 1 may include the screen 215. In this example, the battery 145, the screen 215, and the control module 155 may be external to the insulated thermal envelope 210. Accordingly, for example, the insulated thermal envelope 210 may advantageously maintain a target fresh food temperature passively without being affected by active heat generating elements.

[0026] As shown, the control module 155 includes a control circuit 220, a predetermined freshness time 225, and a predetermined access code 230 associated with the MCFC 200. For example, the predetermined freshness time 225 and the predetermined access code 230 may be stored in a storage module (e.g., non-volatile memory) of the control module 155. For example, the predetermined freshness time 225 may be associated with the MCFC 200. For example, the control circuit 220 may be connected to the electronic lock 140 and the screen 215 of the MCFC 200. For example, the control circuit 220 may activate (e.g., lock, unlock) the electronic lock 140. For example, the control circuit 220 may generate a visual indication at the screen 215 to alert a user that the MCFC 200 is unlocked (e.g., activated). In some implementations, the screen 215 may include a touch screen. For example, the screen 215 may be configured to display information on a front face of the MCFC 200. In some examples, the screen 215 may receive input (e.g., a userinput access code) to enable the user to open the MCFC 200 without their phone (e.g., the mobile device 120).

[0027] In some implementations, the control circuit 220 may be configured (e.g., by software, using a programmable array) to control the electronic lock 140. For example, the control circuit 220 may individually lock the MCFC 200 when the predetermined freshness time 225 associated with the MCFC 200 has expired. For example, after the MCFC 200 is expired, the user may be prevented from opening the MCFC 200 and accessing the food 260 in the fresh food compartment 205. Accordingly, for example, the MCFC 200 may advantageously prevent food poisoning due to expired food.

[0028] In this example, inside the fresh food compartment 205, the MCFC 200 includes a heating pad 235 and / or a cooling pad 240. For example, the heating pad 235 and / or the cooling pad 240 may be disposed (e.g., inserted) by the FFDF 110 to passively regulate and / or maintain aTPL Docket No.: 978-02-WO temperature in the fresh food compartment 205. For example, the heating pad 235 may be configured to regulate the temperature based on a chemical reaction without using electricity. For example, the cooling pad 240 (e.g., a cold gel pad) may include heat absorbing materials to maintain a low temperature within the fresh food compartment 205. In some embodiments, the fresh food compartment 205 may include a moisture absorbent pad 245 to absorb condensation and / or spills. In some embodiments, the heating pad 235, the cooling pad 240, and / or the moisture absorbent pad 245 may be releasably coupled to the box to prevent inadvertent removal by the end consumer.

[0029] In some implementations, the FFORA 125 may be configured to track the MCFC 200 associated with the user of the FFORA 125 through the network 115. For example, the user may determine, from the FFORA 125, whether the food ordered has been stored at the FFCR 105. For example, the user may determine, from the FFORA 125, whether the FFCR 105 has arrived at the user’s facility. For example, the user may determine, from the FFORA 125, whether the MCFC 200 is closed / opened. In various examples, the FFORA 125 may be configured to interact with each of the MCFC 130 individually. In some examples, the control circuit 220 may only open the MCFC 200 when the access code associated with a specific customer of the MCFC 200 is received.

[0030] In various implementations, the control circuit 220 may be configured to operate in a low power mode (e.g., a sleep mode) when no signal (e.g., access code, activation signal) is received at the communication interface 150. For example, the battery 145 may advantageously last for at least six months without replacement. In some implementations, the control circuit 220 may be configured to transmit a low power notification (e.g., to the FFDF 110) when a power of the battery 145 is below a threshold (e.g., less than 10%).

[0031] As an illustrative example without limitation, after the food 260 is inserted into the fresh food compartment 205 and the MCFC 200 is closed within the insulated thermal envelope 210. The control circuit 220 may be selected to operate the MCFC 200 in a sleep mode, for example. In some implementations, upon receiving the predetermined access code 230 to activate the MCFC 200, the control circuit 220 may be configured to open only the MCFC 200 that is associated with the predetermined access code 230. For example, opening only one box associated with the user may advantageously reduce power consumption and extend battery life. For example, the control circuit 220 may be configured to after the predetermined freshness time 225 expires (e.g., after 3 hours), move the MCFC 200 into a lock-out mode. For example, in the lock-out mode, a user may no longer open the MCFC 200 using the predetermined access code 230. Instead, for example, the MCFC 200 may be open only after it is returned to the FFDF 110 by, for example, an administrator using an administrator key.TPL Docket No.: 978-02-WO 100321 In some implementations, the control circuit 220 may generate a notification (e.g., at the screen 215) prior (e.g., 3 minutes, 5 minutes, 10 minutes, 15 minutes) to entering into the lock-out mode. In some implementations, the screen 215 may display a duration of the food 260 being stored in the fresh food compartment 205. In some examples, the screen 215 may update the screen 215 once every hour.

[0033] As shown, the MCFC 200 includes a chain 250. For example, the chain 250 may be configured to chain other boxes in a rack (e.g., the MCFC 130 of the FFCR 105). For example, the chain 250 may advantageously prevent the MCFC 200 from being taken away from the rack illegitimately (e.g., simply walk away with it without entering the predetermined access code 230).

[0034] In some implementations, the MCFC 200 includes a global positioning system tag (GPS tag 255). In some examples, the GPS tag 255 may be activated to transmit a location of the MCFC 200 when the MCFC 200 is activated by the control circuit 220. For example, the FFDF 110 and / or a user of the mobile device 120 may be notified of a location of the MCFC 200 when it is opened. In some implementations, when the MCFC 200 is activated (e.g., unlocked, opened), the control circuit 220 may automatically generate a confirmation signal (e.g., a signature) indicating that food inside the MCFC 200 is received by an authenticated person. For example, the authenticated person may include a patient in a hospital. For example, the patient may have specific allergies, and / or other food restrictions. In some examples, the MCFC 200 may advantageously ensure that a person associated with the MCFC 200 receives the MCFC 200. As an illustrative example, a doctor may prescribe a specific meal to a child with allergies associated with the predetermined access code 230. For example, the MCFC 200 may be configured so that only the person with the predetermined access code 230 (e.g., the child and / or the guardian) may unlock the MCFC 200 and receive the specific meal. For example, after the predetermined access code 230 is received, the control circuit 220 may generate a notification signal to the doctor and / or an administrative system indicating that the child received the specific meal.

[0035] In various examples, the MCFC 130 may be flexibly delivered without a limit of slots of a fixed locker. In some implementations, the MCFC 200 may operate independently to enhance flexibility of a location for delivering food in the MCFC 200 (e.g., for providing lunch in an executive meeting in a conference room instead of in a company canteen). For example, the MCFC 200 may advantageously verify that a right person is taking the right food automatically. Various embodiments may be operable using a low voltage power source (e.g., using 1-2 Volts batteries).

[0036] In various implementations, independent containers (e.g., the MCFC 200) may be stackable & lockable to a rack (e.g., the FFCR 105). In some examples, the MCFC 200 may include a passive insulated thermal envelope (e.g., the insulated thermal envelope 210). For example, the MCFC 200 may include other electronically operated components (e.g., the communicationTPL Docket No.: 978-02-WO interface 150, the battery 145, the electronic lock 140, the control module 155) exterior to the insulated thermal envelope 210. In some examples, the control module 155 may be configured to enter a sleep mode until being prompted by an associated end-consumer (e.g., a user with the predetermined access code 230). For example, the passive insulated thermal envelope may be arranged exterior to the thermal envelope configured to modify the temperature of each of the independent containers.

[0037] In some implementations, each of the independent containers may be operable in a continuous, low-battery mode configured to advantageously prolong the battery life of each of the MCFC. In some implementations, the independent containers may include a control element configured to receive a communication signal to allow retrieval of food by a user.

[0038] FIG. 3 is a flowchart illustrating an exemplary MCFC configuration method. For example, a method 300 may be performed by an operating system in the FFDF 110. For example, the operator may be working in a hospital kitchen. For example, the operating system may be installed in a delivery meal cooking facility. In this example, the method 300 begins in step 305 when a customer order, including a meal order and a predetermined access code, is received. For example, an operating system in the FFDF 110 may receive an order through the FFORA 125 from a user who has specified a meal and an access code for retrieval.

[0039] In step 310, an independent MCFC and the ordered meal are received. For example, the operating system may retrieve the MCFC 200 from storage and a prepared meal based on the user’s order for placement within the MCFC 200.

[0040] At a decision point 315, it is determined whether the battery of the MCFC is functioning correctly. For example, the control circuit 220 may assess the battery 145 to ensure it has sufficient charge. If the battery is not functioning properly, in step 320, the battery of the MCFC is replaced, and the decision point 315 is repeated. For example, the operating system may replace the battery 145 to ensure the MCFC 200 can maintain its operations throughout the delivery process.

[0041] If the battery is functioning correctly, in step 325, a fresh time limit for the ordered meal is set at the MCFC. For example, the operating system may use the control circuit 220 to input a predetermined freshness time 225 based on specific characteristics of the ordered meal.

[0042] In step 330, the predetermined access code is set at the MCFC. For example, the operating system may program the control module 155 with the access code received from the customer order to enable secure access by the end user. In step 335, the ordered meal is enclosed into the MCFC. For example, the operating system may place the prepared meal inside the fresh food compartment 205 and secure the insulated thermal envelope 210 to maintain the meal's temperature.TPL Docket No.: 978-02-WO |0043 | Next, the MCFC is stacked in a delivery rack in step 340, and the method 300 ends. For example, the operating system may place the MCFC 200 into a rack within the FFDF 110 for transport to the final destination after it is secured.

[0044] FIG. 4 is a flowchart illustrating an exemplary MCFC retrieval method. For example, a method 400 may be performed by the control circuit 220 of the control module 155. In this example, the method 400 begins in step 405 when a fresh time limit is received. For example, the control circuit 220 may receive the predetermined freshness time 225 from the FFDF 110 upon initialization of the MCFC 200. For example, the control circuit 220 may receive the fresh time limit via the screen 215. For example, the MCFC 200 may be programmed through the communication interface 150.

[0045] In step 410, a predetermined access code is received. For example, the control circuit 220 may receive the predetermined access code 230 from the FFORA 125 linked to the specific end consumer's order through the communication interface 150.

[0046] Next, a food enclosed signal is received in step 415. For example, the control circuit 220 may receive a signal indicating that the food has been placed inside the fresh food compartment 205 and the MCFC 200 has been securely closed. In step 420, the MCFC is operated in a sleep mode. For example, the control circuit 220 may enter a low-power state to conserve battery life.

[0047] At a decision point 425, it is determined whether the battery is functioning correctly. For example, the control circuit 220 may check the status of the battery 145 to ensure it has sufficient charge to maintain operations. If the battery is not functioning properly, in step 430, a low battery indication is generated. For example, the control circuit 220 may transmit a notification to the FFDF 110 or display a warning on the screen 215 indicating that the battery needs to be replaced.

[0048] If the battery is functioning correctly or after the step 430, it is determined whether the predetermined access code has been received at a decision point 435. For example, the control circuit 220 may monitor the communication interface 150 for an input of the predetermined access code 230 by the end consumer (e.g., from the mobile device 120, from the screen 215). If the access code is received, in step 440, the MCFC is activated, and the method 400 ends. For example, the control circuit 220 may unlock the electronic lock 140 and display a notification on the screen 215, allowing the end consumer to access their meal.

[0049] If the access code is not received, at a decision point 445, it is determined whether the fresh time limit has passed. For example, the control circuit 220 may compare the current time with the predetermined freshness time 225 to determine if a meal enclosed in the fresh food compartment 205 is still within the safe consumption period. If the fresh time limit has passed, in step 450, the MCFC is operated in a lock-out mode, and the method 400 ends. For example, the control circuit 220 may lock the electronic lock 140 to prevent any consumer access to the food 260 inside theTPL Docket No.: 978-02-WO fresh food compartment 205. For example, the MCFC 200 may only be unlocked at the FFDF 110 by authenticated personnel.

[0050] Although various embodiments have been described with reference to the figures, other embodiments are possible. In some implementations, the MCFC 200 may be connected to one or more sensors (e.g., a temperature sensor, an acidity sensor, a conductivity sensor, a moisture sensor). For example, the sensors may monitor (an internal) temperature of a food environment (e.g., within the insulated thermal envelope 210 of each of the MCFC 130). For example, the control circuit 220 may determine whether there is any poor insulation at the MCFC 130. For example, the control circuit 220 may display a visual indication of sensor measurements and / or result of the MCFC 200 at the screen 215 to prompt an administrator to repair the insulated thermal envelope 210.

[0051] In some implementations, the control module 155 may be configured to receive the predetermined access code 230 by listening to a user’s voice. For example, the control circuit 220 may include a voice recognition engine configured to identify, from ambient noise, a pass phrase that matches the predetermined access code 230. For example, when the pass phrase matching the predetermined access code 230 is received, the control circuit 220 may be configured to activate MCFC 200 and / or unlock the electronic lock 140.

[0052] Although an exemplary system has been described with reference to the figures, other implementations may be deployed in other industrial, scientific, medical, commercial, and / or residential applications. In some implementations, the MCFC 130 may be applicable to store other (e.g., miscellaneous) items. For example, the MCFC 130 may be applied to store one or more items ordered by a user (e.g., using the mobile device 120). In some examples, the items may include non-temperature sensitive items (e.g., time-sensitive items, time-sensitive delivery papers). For example, the items may include temperature sensitive items. For example, the temperature sensitive items may include medical supplies. For example, the temperature sensitive items may include biological samples. For example, the temperature sensitive items may include chemical reagents. For example, the temperature sensitive items may include specialized electronics requiring controlled storage environments to prevent degradation.

[0053] In various embodiments, some bypass circuits implementations may be controlled in response to signals from analog or digital components, which may be discrete, integrated, or a combination of each. Some embodiments may include programmed, programmable devices, or some combination thereof (e.g., PLAs, PLDs, ASICs, microcontroller, microprocessor), and may include one or more data stores (e.g., cell, register, block, page) that provide single or multi-level digital data storage capability, and which may be volatile, non-volatile, or some combinationTPL Docket No.: 978-02-WO thereof. Some control functions may be implemented in hardware, software, firmware, or a combination of any of them.

[0054] Computer program products may contain a set of instructions that, when executed by a processor device, cause the processor to perform prescribed functions. These functions may be performed in conjunction with controlled devices in operable communication with the processor. Computer program products, which may include software, may be stored in a data store tangibly embedded on a storage medium, such as an electronic, magnetic, or rotating storage device, and may be fixed or removable (e.g., hard disk, floppy disk, thumb drive, CD, DVD).

[0055] Although an example of a system, which may be portable, has been described with reference to the above figures, other implementations may be deployed in other processing applications, such as desktop and networked environments.

[0056] Temporary auxiliary energy inputs may be received, for example, from chargeable or single use batteries, which may enable use in portable or remote applications.
