Title: Sanitization device for groceries or other objects

Description:
TECHNICAL FIELD 
     Embodiments of the invention relate to portable devises for irradiating and sanitizing the outer wrappings or packaging of groceries, wine bottles, cardboard boxes, or other objects while in transit from a grocery store or other location to home in a safe and controlled environment. Embodiments of the present invention relate to sterilization, e.g., using UVC radiation, ozone, etc., and, more particularly, to the use of such sterilization in both fixed and portable box-type sanitizers. 
     BACKGROUND OF THE INVENTION 
     In general, pathogens such as bacteria and viruses are everywhere within our environment, including on, for example, door handles, counter tops, shopping cart and basket handles, checkout conveyors, public floors, sidewalks, and in the air. Currently, there exist many solutions for cleaning hands from germs, such as hand sanitizer, wet wipes, etc. These products may help people who are on the go or who want a quick solution to cleaning their hands when washing with soap and water is not an option. It is not, however, feasible nor convenient to use chemical wipes and/or cleaning solutions on all grocery or product packaging surfaces that need to be sanitized. And even when more convenient logistically, it is also time consuming to wipe down every product or object acquired from a store and then to clean the area where the objects were placed, such as the kitchen countertop or floor. 
     Disinfection from germs or other pathogens from grocery packaging or other objects is generally done using sanitizer, wet wipes, soap and hot water, bleach or bleach equivalent and similar products that require a consumer to spend time carefully wiping or washing and drying packaging of each item, placing the package from a contaminated surface to a clean surface, repeating the process for multiple items, cleaning the contaminated surface on which the packages were originally placed and storing the cleaned and wiped packages in their intended location such as the refrigerator or pantry. Some packaged items lend themselves well to wiping or washing (e.g., milk bottle) while others do not (e.g., cereal box or bread in paper packaging). This is also a time consuming, imperfect, and tedious process especially when done by a single individual without the assistance of a second “clean” person to process the cleaned items efficiently. 
     Aside from chemical wipes and other cleaning solutions, short-wavelength ultraviolet (UVC) light is a proven and effective way to remove bacteria, viruses, and other pathogens. UVC sanitizers are well known for use in sterilizing all manner of objects including contact lenses, combs, cell phones, safety goggles and other small items. Often only a single source of radiation is employed and, as such, there are often areas on an object to be sanitized that are shadowed from the UVC radiation produced from the single source. Current UVC options for removing germs/bacteria are often expensive and are not readily accessible to the average consumer and/or often have a singular specific use. Furthermore, there are risks with UVC light. For example, UVC light may cause skin cancer and/or cataracts when exposed to the user. Therefore, a need exists for a device that is safe for humans and may be used to sanitize surfaces, such as grocery packaging, in a quick, easy, safe manner, to eliminate pathogens in a form factor that is readily available and accessible for everyday use by the average consumer. 
     In light of the aforementioned drawbacks and limitations, there exists a need for a portable or mobile device for use in a vehicle, which may also be fixed at a residence, for providing quick and safe sterilization of outer wrappings or packaging of groceries, wine bottles, cardboard boxes, or other objects while in transit from the point of acquisition of said objects to the home with minimal activity involved by the user. Such devices may advantageously be used to substantially sanitize multiple objects at the same time. Devices that satisfy this unmet need may further use minimal irradiation or sterilization to provide a quick and effective method for preventing the spread of viruses, bacteria or other pathogens without endangering the safety of the user. 
     SUMMARY OF THE INVENTION 
     Embodiments of the present invention provide systems and methods for the quick, safe, and portable sterilization of the outer wrappings or packaging of groceries, wine bottles, cardboard boxes, or other objects that may be deployed for use within the trunk of a vehicle. Fixed deployments are also contemplated for home use. The systems and methods for sanitizing disclosed herein may be used on the outer wrappings or packaging of groceries, wine bottles, cardboard boxes, or other objects after they have been on the shelves of a grocery store, stocked by store employees and exposed to airborne pathogens from other customers, a grocery cart or basket, the grocery conveyor belt, checkout clerk, etc. 
     Embodiments of the present invention are directed towards a box-type-portable sanitizer using C-band Ultra-Violet (100-280 nm) (“UVC”) radiation that comprises a hollow rectangular box that defines a volume with a door on one end such as the top. The box may comprise hollow ¼ inch construction of all walls, including the top and bottom. Other embodiments comprise solid wall construction without any space or gap between inner and outer walls. Mounted facing the interior volume of the box are, according to one embodiment, a plurality of strategically placed 275 nm UVC LED SMD 3535 Deep LED Diode UV Chip or similar UVC radiation LEDs, UVC radiation bulbs, or similar UVC lightings that, when powered, are each operative to generate UVC radiation. Such UVC lights may be mounted between the walls of the box such that a given UVC light emits UVC radiation through one or more openings in the interior wall of the box. Affixed to the bottom of the box may be a plurality of wheels to allow for easy movement of the sanitizing box. Alternatively, such wheels may be housed within the bottom interior wall (or a cavity formed therethrough or therein) for deployment by the user as needed, e.g., “pop out” wheels. 
     Shelves may be used within the box to hold items for sterilization apart from one another and thereby achieve sterilization of increased surface area of the goods. Shelves may comprise minimally opaque components for placement within the volume that the interior of the box defines into which a user may locate an object(s) to be irradiated and sanitized. According to some embodiments, the upper shelves are height adjustable with an easy click-in/rail system basket design. In operation, an object (or multiple objects) to be irradiated and sanitized may be placed inside the box, the door closed, and the lights powered for one or more periods of time such that any pathogens present on the object(s) to be sanitized are irradiated by the UVC radiation. Shelves with minimal opaque structures are used to support the object(s) to be sanitized and separate the object(s) to be sanitized from the lamps, as well as each other, thereby allowing the UVC radiation to pass between and fully bathe the objects. In accordance with mobile embodiments, the device is configured to utilize typical 12-volt DC power that can be obtained by, e.g., (i) plugging into a cigarette lighter/USB adapter of a vehicle trunk or interior of vehicle through a trunk pass through; (ii) plugged into an external battery power attachment; (iii) a wall outlet; and/or (iv) hard wired into a vehicle electric system, etc. 
     According to one embodiment, a sanitizer using radiation comprises a hollow housing with an aperture, the housing being generally opaque to the radiation utilized. Mounted to the interior surfaces of the housing are radiation sources that produce radiation when powered. In operation, multiple objects to be sanitized are placed within the interior and the radiation sources powered, thereby sanitizing by radiation any pathogens present on the objects be irradiated. An easily adjustable shelving system that is substantially non-opaque to the radiation utilized, such as wire shelving with minimal opaque surfaces, may be used to support the objects to be sanitized. Depending on size, the portable box allows for multiple objects to be sanitized at the same time. The sanitizer in certain embodiments includes a plurality of UVC radiation sources mounted in the interior of the housing so as to surround the object to be sanitized on multiple sides. 
     According to another embodiment of the present invention, the system comprises a 12-volt DC powered, portable opaque box that defines an interior volume to receive groceries or other objects. Positioned on the interior of the box and operative to irradiate objects contained within the interior volume of the portable opaque box are one or more ultraviolet lights, which according to one embodiment are germicidal 275 nm UVC LED SMD 3535 Deep LED Diode UV Chips or similar UVC radiation LEDs, UVC radiation bulbs, or similar UVC lightings that properly allow the UVC light wavelengths to reach the outer surfaces of the objects for maximum germicidal effectiveness. A number of shelves or trays are disposed within the volume to as to support the items for sterilization, for example, one (1) full size, removable, thin yet durable, easy-to-clean shelf (such as epoxy-coated steel or other non-corrosive UVC/ozone stable materials) with a minimal amount of opaque coverage in a pattern for maximum exposure of the objects to UVC light on the bottom of the box set at specified height with legs and handles and two (2) half size, removable, adjustable, thin yet durable, easy-to-clean shelves (such as epoxy-coated steel or non-corrosive UVC/ozone stable materials) with a minimal amount of opaque coverage in a pattern for maximum exposure of objects to UVC light. Embodiments further comprise a timer and safety mechanism (such a as magnetic switch that must indicate closure of a lid to the box prior to and during operation) to ensure the device is not operational unless the device is securely closed. A control board with a timer display and software is deployed to control the time of use for maximum effectiveness and safety cut off control. 
     According to still further embodiments of the present invention, the system comprises a 12-volt DC powered, portable opaque box, e.g., constructed of HDPE or other UVC/ozone stable material, to receive and strategically position groceries or other objects within the main body of the portable opaque box. Within the interior of the box are one or more 12V 10 g/h ceramic Ozone generator(s), e.g., located at the bottom of the box, to allow air sterilization and germicidal action to reach the outer surfaces of the packaging and therefore provide maximum germicidal effectiveness. According to certain embodiments, contained within the volume are one (1) full size, removable, thin yet durable, easy-to-clean, shelf with a minimal amount of opaque coverage in a pattern for maximum exposure of objects to ozone and set at specified height with legs and handles, and two (2) half size, removable, adjustable, durable, easy-to-clean, shelves with a minimal amount of opaque coverage in a pattern for maximum exposure of objects to ozone. A timer and safety mechanism to ensure the device is not operational unless the device is securely closed. A control board with a timer display and software is deployed to control the ozone generation time of use for maximum effectiveness and in accordance with any proscribed safety requirements. 
     According to another embodiment of the present invention, a method of irradiating and sanitizing the outer wrappings or packaging of groceries, wine bottles, cardboard boxes, or other objects over a period of time comprises the steps of: placing the objects inside the portable opaque box, which may be kept inside a vehicle trunk or at a fixed location, on shelves in a configuration that allow for the irradiating agent to come into contact with surfaces of the objects; engaging a safety switch to ensure operation only while the box is securely closed, and setting a time to control the amount of time over which the objects in the portable opaque box are irradiated. 
     In accordance with another aspect of the present invention there is provided a sanitizer apparatus. The sanitizer comprises a hollow rectangular box, which may be made from ¼ inch diameter sealed walls, defining an interior having six surfaces covered in a material that is opaque to UVC radiation to the outside of the box and may reflect UVC light back into the interior of the box and a door providing a re-sealable closure for an access aperture in one of said six surfaces. The aperture allows for placement of multiple objects to be sanitized within the interior. A bottom UVC radiation source may be mounted facing the interior of the box in said interior of said housing with a support structure of set and/or adjustable shelves mounted in said interior of said housing above said bottom UVC radiation sources, said support structure provided to support said objects to be irradiated and sanitized. A plurality of UVC radiation sources may be positioned and mounted in the interior of the box so as to be facing the interior of the box, irradiating, and surrounding said objects in UVC light for sanitization. Such UVC radiation sources may be placed in a space that may exist in a space between the walls comprising the box with the UVC radiation source positioned through said spaces. 
     According to still further embodiments of the present invention, the method of irradiating and sanitizing the outer wrappings or packaging of groceries, wine bottles, cardboard boxes, or other objects over a period of time comprises the steps of: placing the objects inside the portable opaque box, which is kept inside a vehicle trunk or at a fixed location, on shelves in a configuration that allow for ozone to come into contact with surfaces of the objects; engaging a safety switch to ensure operation only while the box is securely closed, and setting a time to control the amount of time over which the objects in the portable opaque box are exposed to an ozone generation source. The method may further comprise locking the box for a period of time subsequent to operation of the ozone generation source so as to provide sufficient disinfecting of the objects contained therein.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Throughout the present specification, the technical terms and abbreviations are to be interpreted in the broadest sense of the respective terms, and include all similar items in the field known by other terms, as may be clear to persons skilled in art. Restriction or limitation if any referred to in the specification, is solely by way of example and for understanding the present invention. Also, there is no stringent rule as far as the visual layout of the apparatus is concerned. While the drawings display the different embodiment, the invention would cover all other variants that seek to achieve the same object as that of the present invention. 
     In different exemplary embodiments, the systems and methods described herein are directed towards portable devices and methods for providing sanitization while in transit or at home of the outer wrappings or packaging of groceries, wine bottles, cardboard boxes, or other objects. The process of disinfecting objects with UVC light requires that the object be exposed to the correct wavelength of UVC light for a period of time. The interior of a vehicle trunk in conjunction with the portable box set forth herein, provides an excellent platform through which to accomplish the disinfection process while completing point-to-point travel (or stationary if additional items need to be disinfected after the completion of disinfecting a first batch). The interior of the home or garage is an acceptable location for the device as well. 12-volt DC power is supplied via a vehicle charger, e.g., cigarette to USB adapter, an external battery supply, a hard-wired adapter kit for the vehicle or a regular power plug may suffice for providing power to the essential components as explained in connection with the exemplary embodiments. 
       FIG. 1  illustrates an exploded view of a sanitization box in accordance with one embodiment of the present invention that is operative to sanitize the outer wrappings or packaging of groceries, wine bottles, cardboard boxes, or other objects. Such sanitization, as is explained in greater detail herein, can be provided by a number of mechanisms including, but not limited to, UVC sterilization, ozone sterilization, etc. The sanitizing box in accordance with the embodiment of  FIG. 1  comprises a housing having left and right sides, front and back sides, and top and bottom sides, thereby forming an opaque box  100 . According to one embodiment, the box  100  is constructed of hollow ¼ inch walls made of High-density polyethylene (“HDPE”) or other similar material that is opaque to UVC radiation and UVC stable. Other embodiments comprise solid wall construction without any space or gap between inner and outer walls. Advantageously, the material may be coated with an adhesive and a UVC reflective material applied to the inside surface. 
     The box  100  may be sized so as to accommodate multiple packages or other items by receiving them through a top removable door  108 , which may be configured with side indentations  110  to allow for easy lifting and access to the interior volume  102  of the box  100 . The interior volume  102  of the box  100  may be outfitted with one or more shelves  104 ,  106 A and  106 B that may be removable and adjustable and may further be substantially UVC transparent. Also, embodiments allow for height adjustment by providing a rail system  112  for certain shelves so as to accommodate certain objects based on surface area to be irradiated and sanitized, yet optimized to allow any given sanitization agent, e.g., UVC light, ozone, etc., to achieve contact with the maximum amount of surface area. 
     According to the embodiment of  FIG. 1 , the box  100  is compact such that it can fit easily inside the trunk of an average vehicle. Alternative embodiments are directed towards larger sizes for crossover, SUV, or home use, as well as the use of a side opening door rather than top opening door. The opaque box  100  with its top door  108  creates a closed environment in which the objects can be sanitized inside a normal vehicle trunk, for example, through the application of UVC light or ozone. The box  100  may house all the major components of the sanitizing system, although embodiments that distribute certain subsystems outside the box  100  are contemplated as falling within the scope of the present invention. 
     To control operation of the sanitization mechanism, the box  100  implements electronics  114  that include a timer mechanism that controls timing of the release and distribution of sanitizing agent within the box. In one embodiment, electronics  114  further comprise a control module in communication with the timer such that for the duration of the timer counting down to a zero time the control module executes program code, which may be embedded code, to control operation of an array of 275 nm UVC LED SMD 3535 Deep LED Diode UV Chips, UVC radiation LEDs, UVC radiation bulbs, or similar UVC lightings  116  that are disposed within the interior volume of the box, which may comprise disposing one or more lights on the door  108  of the box  100 . The UVC LEDs  116  may, alternatively comprise cold cathode UVC germicidal lamps with optional ozone lamps (not shown) or any other suitable unbreakable UVC lamps. Similarly, where the sanitizing agent is ozone, the control module executes program code to control operation of, e.g., a 12V 10 g/h ceramic ozone generator. 
     In an exemplary embodiment of the present invention, the portable disinfection box  100  as depicted in  FIG. 1  comprises a set of no less than sixteen (16) 275 nm UVC LED SMD 3535 Deep LED Diode UV Chips, UVC radiation LEDs, UVC radiation bulbs, or similar UVC lightings  116 , which are placed at periodic locations on each internal surface of the box  100 . In certain embodiments, such array of UVC LED lights  116  are mounted between the opaque walls of the box  100  and facing the interior through corresponding openings so as to allow the lights to irradiate the objects on the interior  102 . UVC reflective material may be used to cover the interior  102  walls of the opaque box  100  and serve as an aid to the dispersal of the UVC radiation within the box  100 . In one embodiment of the present invention, the UVC reflective material is polished aluminum diamond plate or UVC reflective coating identified in U.S. Pat. No. 9,657,177, which is hereby incorporated by reference in its entirety, to reflect any UVC radiation that reaches an interior surface  102  of the box  100  back toward the object to be sanitized. As will be apparent to a person of ordinary skill in the art, with these or other highly-reflective interior surfaces, the UVC LEDs  116  need not necessarily be mounted proximate to all six interior surfaces of the sanitizer  100  and, instead, a fewer number interior surfaces may suffice. The UVC radiation, coupled with structural environment inside the apparatus, thus promotes germicidal action by eliminating viruses and other pathogens through irradiation. 
     The use of shelving  104 ,  106 A and  106 B, by various embodiments of the invention helps promote such germicidal activity. For example, the embodiment of  FIG. 1  comprises one (1) lower  104  and two (2) upper shelves or racks  106 A and  106 B for holding objects to be sanitized. The lower shelf  104  may be supported by feet at a specified height, as well as be removable with handles for easy clean up. In the present embodiment, the upper two shelves  106 A and  106 B are half the size of the bottom shelf  104  with a rail/basket design  112  to keep the objects contained. Each basket is attached to a set of adjustable rails  112  with an easy clip in system that locks in place when desired height is reached—this provides stability and allows for upward adjustment or removal with an upward pull motion. A given set of rails  112  are embedded into the box  100  and firmly supported to handle the weight of the objects affixed to them. 
     The shelves  104 ,  106 A and  106 B, may be comprised of thin metal wire design with minimum opaque elements that allows for maximum exposure of the grocery packaging or other objects to the UVC light wavelengths. While there is no limit to the size and number of objects that can be placed in the box  100  other than the maximum volume of the box interior  102  and proper closing of the lid  108 , it is important to note that in order to properly disinfect the packaging or outer wrapper of a given object, such packaging or outer wrapper needs to be exposed to the disinfectant, e.g., UVC light or ozone. Accordingly, it is important for the object to be located on the provided shelves  104 ,  106 A and  106 B with space between them and not stacked on top of each other, which has the undesirable effect of preventing surfaces from achieving sufficient exposure to the disinfectant. 
     As further illustrated in the embodiment of  FIG. 1 , the box  100  comprises a door  108 , which here is a top door, although various embodiments may utilize other door configurations. The door  108  comprises a safety mechanism and may also implement a lock that secures the box  100  during sanitization. The safety mechanism  118 A and  118 B may be one or more safety contacts/switches  118 A in communication with corresponding contacts  118 B on the box  100  that together are utilized to ensure a closed environment respectively for the safe operation of the device. Although embodiments allow for the door  108  to be fully removable for ease of shelf  104 ,  106 A and  106 B adjustment and placement of objects into the box  100 , the device is not operable without the door  108  being fully closed. If the door  108  is opened when the sanitizer is in use, i.e., when the UVC LEDs  116  are receiving power from a power source  120 , the door safety mechanism  118 A and  118 B may interrupt power  120  to the UVC LEDs  116 . This is beneficial, since it is known that accidental exposure to UVC radiation can cause corneal or other severe burns. The electronic components described herein may be disposed within an electronic compartment in the door  108  that is provided with an access door to provide for maintenance. 
     An optional component for inclusion as part of the sanitization box  100  is the use of a lamp monitor (not pictured) that measures the output of UVC lights that might be used for sterilization. During exposure, the lamp monitor may measure and provide an indication to the user of the power output of the UVC LEDs  116 . This feature may be useful where the power output of the UVC LEDs  116  diminishes. As the power output of the UVC lamps  116  diminish, it is necessary to increase the duration of exposure of an object to be sanitized to radiation from the UVC LEDs  116  to properly sanitize the object. Consequently, according to the indication of power output provided by the lamp monitor, the operator may set the timer appropriately for the next set of objects to be sanitized. A person of ordinary skill in the art should be able to determine a necessary duration of radiation from the amount of radiation per unit time indicated by the lamp monitor and the desired amount of radiation to which is it is desired to expose the objects to be sanitized. Additionally, the lamp monitor may be configured to indicate when the power output of the UVC lamps  116  has diminished to a level below a predetermined threshold. Such an indication may be interpreted as a sign that one or more of the UVC lamps need to be changed. 
     By way of exemplary operation when utilizing UVC radiation, objects to be sanitized is placed in the interior  102  of the sanitizer box  100 . The top door  108  is closed, the UVC LEDs  116  are switched on, and the objects to be sanitized are bathed in UVC radiation. Due to the placement of UVC LEDs  116  on many, if not all, of the interior  102  sides of the sanitizer box  100 , very little of the surface area of the objects to be sanitized are shadowed from the UVC radiation. Additionally, the objects to be sanitized are supported upon the specially located shelves,  104 ,  106 A and  106 B, which are designed to engage in minimal blockage of the UVC radiation, and, therefore, do not significantly shadow the objects to be sanitized from the UVC radiation. 
     By way of further description of the exemplary operation, an operator of the sanitizer box  100  opens a door  108  to the box  100 , which may comprise unlocking a door lock that is operative to secure the door  108  and opens the sanitizer box  100  to expose the interior volume thereof  102 . The operator may place objects to be sanitized upon the bottom shelf  104  with space between the objects, adjusting the top shelves,  106 A and  106 B, and placing the objects thereon in a desired configuration, followed by securing a door lock when present. The operator may then use the electronics  114 , specifically the timer, to select a desired duration of exposure and activate master power  120  to power the sanitizing mechanism, e.g., UVC LEDs or ozone generator. When the selected duration of exposure expires, the master power  120  may be automatically powered off. The user may then open the door  108  to expose and remove the objects, which may now be considered to be sanitized. 
     Thus the individual components, as explained above in connection with the various exemplary embodiments, tend to perform their own specific function for the sanitization process that, in combination with the portable sanitization box  100 , creates a micro-environment inside a regular vehicle trunk, SUV, crossover, or other vehicle, home or other location, to sanitize multiple objects at the same time in a very easy, safe and convenient manner Additionally, those skilled in the art will understand that the shape of the housing is not necessarily limited to that of a rectangular box. Other shapes, such as spherical and conical, may also be useful in certain applications. 
       FIG. 2  illustrates a partially constructed perspective view of a portable sanitizing box  100  in accordance with one embodiment of the present invention. The view of  FIG. 2  presents the shelves  104 ,  106 A and  106 B, illustrated in  FIG. 1  set into the interior volume  102  of the box  100 , aligned therein through the use of the rails  112 , the set of which maintain alignment of the shelves  104 ,  106 A and  106 B within the interior volume  102  of the box  100 .  FIG. 3  continues the evolution begun in  FIGS. 1 and 2  by illustrating a perspective view of a closed portable sanitizing box  100  in accordance with one embodiment of the present invention. When closed, the box  100  meets flush with the door  108  to seal the interior volume of the box and prevent the leakage of UVC light, ozone, or other sanitizing agent from escaping the interior volume of the box  100 . When unlocked, the door  108  may be opened through use of the side indentations  110 , which provide a convenient point for the operator to grip the door for opening and exposure of objects in the interior volume. 
       FIG. 4  illustrates a perspective view of the shelf assembly for a portable sanitizing box system in accordance with one embodiment of the present invention. In particular, the embodiment of  FIG. 4  presents the adjustable locking system that the shelves  106 A/ 106 B may employ to maintain a specific height that the operator desires, which is shown in detail as a top-down view  406  and cross-sectional view  408 . When an operator places a given shelf in the sterilization box, he or she aligns one or more shelf locks  402  into corresponding tracks  112  that may be affixed to the inner walls of the sterilization box. The exemplary shelf lock  402  is built around the framework of the shelves  106 A/ 106 B, in this instance built around the wire framework that comprises the shelves  106 A/ 106 B. In this exemplary configuration, the locking mechanism is set at a distance between the cross (center of the radius) and center rotation that is slightly bigger than the distance between the watt of the channel and the eccentric in the vertical position. An operator moves the shelf-lock mechanism lever  410  into the locked position by rotating it down (or away from the wall) and having it  412  engage the wall. In the unlocked position, the shelf lock swivels freely with the shelf lock  402  hanging in a vertical position because it is heavier on the bottom. 
     In operation, the user positions the shelves  106 A/ 106 B in the corresponding rails  112  starting at the top opening and lowers it to reach the desired height location. When the desired height is reached, the user manually rotates the shelf lock  402  down to secure the shelf  106 A/ 106 B in place against the wall of the rail  112 . The shelf-lock mechanism  402  may engage the wall of the rail and locks into place by reducing the radius, which serves to hold the shelves  106 A/ 106 B in place. To raise or remove the shelf  106 A/ 106 B, the user lifts the shelf  106 A/ 106 B with the handles and releases the shelf-lock mechanism  402  by the upward friction motion. This allows the user to quickly remove the shelf without having to manually unlock the shelf-lock mechanism. 
     As discussed herein, embodiments of the invention are formed for disposal within or integration with the trunk  508  of a vehicle.  FIG. 5  presents a vehicle  504 , such as car, truck, SUV, or other vehicle, with an exemplary sanitation box  502  in accordance with the various embodiments of the invention disposed in its trunk  508 . The sanitation box  502  may be wired  506  into the power system of the vehicle, which may be configured to provide power to the sanitation box  502  with or without the vehicle  504  being in operation. Power may alternatively be supplied by external batteries or other power source. When the trunk door  510  is closed, the sanitation box  502  is securely enclosed within the vehicle  504  and is therefore safe from tampering. Embodiment also comprise the sanitation box  502  being affixed to a floor of the trunk  508  of the vehicle  504 , as well as unaffixed and removeable. When removeable, the wire  506  to the vehicle power system, when present, may comprise a plug or similar removeable connector. 
       FIGS. 1 through 5  are conceptual illustrations allowing for an explanation of the present invention. Those of skill in the art should understand that various aspects of the embodiments of the present invention could be implemented using different materials, fasteners, and minor design modifications.
