Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a divisional of U.S. patent application Ser. No. 16/952,590, filed Nov. 19, 2020, which is a continuation of U.S. patent application Ser. No. 16/382,728, filed Apr. 12, 2019, which issued into U.S. Pat. No. 10,875,678 on Dec. 29, 2020 and claims the benefit of U.S. Provisional Application No. 62/760,672, filed on Nov. 13, 2018, each of which is hereby incorporated by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     This disclosure relates to a registration system for air flow within boxes. More specifically, this disclosure relates to a box insert with vertical rails. 
     BACKGROUND 
     Home delivery of food is becoming more common as the process becomes more efficient and costs go down. Delivery boxes may alternatively need to keep the food hot or cold enough to, for example, prevent bacterial growth, prevent melting or congealing of the food, or simply maintain the edibility, texture, and flavor of the food. Another consideration for the type of box to use is its impact on the environment, as it relates to the reusability and recyclability of the boxes. Polystyrene foam boxes are prevalent in the food-delivery industry because of their low cost, but they are not commonly recycled. Thus, they take up a disproportionate volume of landfill space. 
     Heating and cooling elements are often placed in containers along with food or other perishable items. Direct contact of food with these temperature elements may cause damage to the food. Separating the temperature element from the food with dividers can insulate the element too much, preventing the food from being cooled or heated to the desired temperature.

     DETAILED DESCRIPTION 
     The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and the previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, and, as such, can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. 
     The following description is provided as an enabling teaching of the present devices, systems, and/or methods in its best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the present devices, systems, and/or methods described herein, while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof. 
     As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an element” can include two or more such elements unless the context indicates otherwise. 
     Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. 
     For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances. 
     As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. 
     The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list. Further, one should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect. 
     Disclosed are components that can be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutation of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems. This applies to all aspects of this application including, but not limited to, steps in disclosed methods. Thus, if there are a variety of additional steps that can be performed it is understood that each of these additional steps can be performed with any specific aspect or combination of aspects of the disclosed methods. 
       FIG.  1    shows in one exemplary aspect an exterior piece  100  of an insulated box  2400  (shown in  FIG.  25   ) in an unassembled configuration as a blank.

The fold lines  140   a,b,c,d  joining the middle portions  110   a,b,c,d  to the upper portions  120   a,b,c,d  can form a top outside edge  210 . The fold lines  140   a,b,c,d  joining the middle portions  110   a,b,c,d  to the lower portions  112   a,b,c,d  can form a bottom outside edge  220 . The side strip  128  can be affixed to the first subpanel  102   a  by staples, hot melt glue, or other adhesives known in the art, or with no adhesive at all. 
       FIG.  3    shows an exemplary aspect of an insulator  300  that can be used in the insulated box  2400 . The insulator  300  can form a loose fill (not shown) or another configuration known in the art. In the current aspect, the insulator  300  can comprise insulator pads  310 . The insulator pads  310  can comprise a variety of materials known in the art, such as polystyrene and/or cellulose. The insulator pads  310  can comprise a bottom insulator  320  and side insulators  330   a,b,c,d . The side insulators  330   a,b,c,d  can comprise a first, second, third, and fourth side insulator  330   a,b,c,d , respectively. The first and third side insulators  330   a,c  can be shorter than the second and fourth side insulators  330   b,d . The side insulators can also comprise a single insulator pad (not shown) extending circumferentially around an interior piece  500 . 
       FIG.  4    is a perspective view of the partially assembled insulated box  2400 . The insulator pads  310  are placed inside the assembled exterior piece  100 . The bottom insulator  320  can cover, or proximately face, the lower portions  112   a,b,c,d  (not shown) of the exterior piece  100 . The bottom insulator  320  can fully extend to the bottom outside edge  220 . The side insulators  330   a,b,c,d  can alternate shorter and longer. For example, in the current aspect, the first side insulator  330   a  can be configured to proximately face the first middle portion  110   a  (not shown). Likewise, the second, third, and fourth side insulators  330   b,c,d , respectively, can be configured to face the corresponding numbered middle portions  110   b,c,d.    
       FIG.  5    shows the interior piece  500  of the insulated box  2400  in an unassembled configuration. The interior piece  500  can comprise a bottom panel  510 , side panels  520   a,b,c,d , and fold lines  530   a,b,c,d  joining the bottom panel  510  to the side panels  520   a,b,c,d . An interior surface  502  faces out of the page in  FIG.  5   . Alternating side panels—for example, a first and a third side panel  520   a,c —can comprise a middle tab  522   a,b  and a side tab  524   a,b,c,d . The middle tabs  522   a,b  can be joined to the side tabs  524   a,b,c,d  by fold lines  526   a,b,c,d . A second and a fourth side panel  520   b,d  can lack fold lines. The interior piece  500  can be formed from a single flat piece with side panel cuts  540   a,b,c,d  separating the side panels  520   a,b,c,d  from each other. Thus, a blank of the interior piece  500  can be configured such that each side panel  520   a,b,c,d  is not connected to any other side panel  520   a,b,c,d , except only indirectly through the bottom panel  510 . The side panel cuts  540   a,b,c,d  can form angles with the fold lines  526   a,b,c,d , the angles being approximately 45 degrees. The side panels  520   a,b,c,d  can form side interior walls of the assembled insulated box  2400 .

The box insert  1200  with vertical rails  1220  can also be used with or without the register  1600  to maintain a uniform temperature and humidity level within the insulated box  2400 . The spaces  1420  between the vertical rails  1220 , the cutouts  1620  exposing the bottom  1410  of the cavity  710 , and the holes  1610  in the register  1600  can all facilitate air flow and by diffusion and convection. 
     The registration system  1800  can be configured to place perishable items such as food (not shown) on one side of the register  1600  and a heat transfer element such as an ice pack (not shown) on the other. The ice pack can be place above the food to allow cooling by cold air flowing downward. Multiple registers  1600  can be used. 
     One should note that conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular aspect. 
     It should be emphasized that the above-described aspects are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the present disclosure. Any process descriptions or blocks in flow diagrams should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process, and alternate implementations are included in which functions may not be included or executed at all, may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present disclosure. Many variations and modifications may be made to the above-described aspect(s) without departing substantially from the spirit and principles of the present disclosure. Further, the scope of the present disclosure is intended to cover any and all combinations and sub-combinations of all elements, features, and aspects discussed above. All such modifications and variations are intended to be included herein within the scope of the present disclosure, and all possible claims to individual aspects or combinations of elements or steps are intended to be supported by the present disclosure.
