These teachings relate to product packaging and, more specifically, to the shipping of frozen or chilled products from shipping sources to shipping destinations using packages that protect the product from damage and preserve the product from spoilage.
Various types of products are shipped from shipping sources (e.g., warehouses) to shipping destinations (e.g., homes of consumers). Some products that are shipped may need to be kept frozen (or chilled) during the shipping process in order to prevent the spoilage of these products. Additionally, many types of products typically need to be protected from damage occurring along the shipping route. To take two examples, pizza or ice cream may need to be kept frozen while being shipped as well as being protected from damage that might occur during the shipping process.
Standard-sized packages or boxes are often used to ship products. To prevent spoilage, these standard shipping containers sometimes include predetermined amounts of refrigerant materials that are used to cool the products. That is, the amount of such refrigerant materials cannot be varied. As for protection from damage, only standard protection structures are offered by these previous approaches.
Unfortunately, these previous approaches sometimes resulted in wasted packing materials and wasted amounts of refrigerant being used since the item may be, for example, much smaller than the shipping package, and not need as much of the provided refrigerant in order to be preserved. In other situations, the amount of refrigerant was too little, thereby allowing the product to spoil or otherwise become unusable before the product was delivered. In still other examples, the amount of refrigerant was adequate, but the structure of the package was inadequate to protect the product from damage that occurred to the package along the shipping route.
The above needs are at least partially met through the provision of approaches that optimize the structure and amount of refrigerant in a package, wherein:
Generally speaking, a system obtains various types of information including customer preferences about how the customer wants their product (e.g., a perishable product) delivered (e.g., time of day), physical characteristics of the product (e.g., dimensions or cold chain requirements), and/or the weather data along the delivery route (e.g., hot weather). Using this information, the package structure and amount of refrigerant placed in the product structure are dynamically optimized so as to both provide adequate protection for the product and to adequately cool or preserve the product during the shipping and delivery process.
In many of these embodiments, a system that is configured to optimize package structure and an amount of refrigerant for the shipment of refrigerated products includes a user interface, a database, at least one sensor, and a control circuit. The user interface is configured to receive consumer preference information from a customer. The customer preference information identifies one or more preferences of the customer concerning the timing or method of shipping a product from a shipping source to a shipping destination according to a delivery route. Other examples are possible.
The database is coupled to the user interface and is configured to store the customer preference information. The database is also configured to store product information. The product information may be physical characteristics or cooling requirements of the product. Other examples are possible.
The sensor is configured to obtain weather information concerning weather conditions occurring along the delivery route. For example, the sensor may obtain temperature, wind, pressure, or precipitation data relating to conditions occurring along the route.
The control circuit is coupled to the database, the user interface, and the at least one sensor. The control circuit is configured to determine an optimal package structure and an amount of refrigerant to insert into the package structure based upon the product information, the consumer preference information, and the weather information. The optimal package structure and the amount of refrigerant are selected so as to be an optimized combination that is effective to both protect the product from damage and preserve the product from spoilage.
The package construction apparatus is coupled to the control circuit. The package contraction apparatus is configured to construct a package to contain the product according to the optimal package structure and to insert the amount of refrigerant into the structure as determined by the control circuit.
In aspects, the optimized package structure is designed so as to optimize a thickness of the package or a shape of the package. Other characteristics may also be optimized. In some examples, the optimal package structure is a honeycomb configuration. In examples, the honeycomb configuration includes gaps into which the refrigerant is selectively inserted.
In other aspects, the optimal package structure includes a plurality of compartments to hold a plurality of products. That is, the overall package is divided into multiple compartments. The multiple compartments may have varying protection structures and varying amounts of refrigerant.
The products may be a wide variety of types of products. In examples, the product may be a frozen product, a refrigerated product, or a chilled product. Other examples of products are possible.
In some examples, the refrigerant is dry ice. Other examples of refrigerants (or combinations of refrigerant materials) may also be used.
The package construction apparatus can utilize a variety of different processes and can be configured in a number of different ways. In one example, the package construction apparatus utilizes a printing process to construct the package.
In still others of these examples, the physical characteristics of the product include product dimensions, product weights, product types, or cold chain requirements. Other examples are possible.
The package (or the components of the package) can be disassembled and re-used. For example, the walls of a first package (having a honeycomb structure) can be disassembled from the first package and re-assembled into new packages.
In others of these embodiments, consumer preference information is collected from a customer. The customer preference information identifies one or more preferences of the customer concerning the timing or method of shipping a product from a shipping source to a shipping destination according to a delivery route.
The customer preference information is stored in a database. The database also stores product information such as the physical characteristics or cooling requirements of the product. Weather information concerning weather conditions that occur along the delivery route is also collected.
An optimal package structure and an amount of refrigerant to insert into the package structure are determined based upon the product information, the consumer preference information, and the weather information. The optimal package structure and the amount of refrigerant are an optimized combination that is effective to both protect the product from damage and preserve the product from spoilage. A package is constructed to contain the product according to the optimal package structure and the amount of refrigerant is inserted into the structure.

The rows 456 represent the amount of refrigeration provided by the package and are divided into high, medium, and low. By a “high” amount, it is meant the product is extremely susceptible to spoilage and (potentially) extra refrigerant is needed to keep the product cold enough so that it will be preserved when being transported to the shipping destination. By a “medium” amount, it is meant that a moderate amount of refrigerant is needed. Although the amount of refrigerant is not maximized, some amount of refrigerant is still needed. By a “low” amount, it is meant that little or no refrigerant is needed to preserve the product when it is shipped to the destination.
The matrix 452 consists of cells 401, 402, 403, 404, 405, 406, 407, 408, and 409. Each cell corresponds to a row and column, and consequently a level of structural protection and amount of refrigeration provided. For instance, cell 401 represents products needing packages that offer high structural protection and provide high amounts of refrigeration. Each of the cells is suitable for different types of product.
Cell 401 is for products such as chocolate covered ice cream products (e.g., Christmas tree shaped chocolate products). Cell 402 represents products such as frozen fruit. Cell 403 is for products such as frozen meat.
Cell 404 is for products such as cooked appetizers. Cell 405 represents products such as frozen vegetables. Cell 406 is for products such as blocks of cheese.
Cell 407 is for products such as ordinary ice cream (e.g., not covered by chocolate). Cell 408 represents products such as refrigerated meat. Cell 409 is for products such as frozen juice concentrate.
It will be appreciated that these are examples only, and that other examples are possible. It can be seen that a product type may be determined, mapped to a particular cell, and then an appropriate package constructed for the product.

It will be appreciated that this is only one example of a mapping. Other inputs will potentially produce different amounts (e.g., low or medium) amounts of refrigerant. Moreover, the terms high, medium, and low map to numerical values. For instance, “high” may always map to a first predetermined amount of refrigerant, “medium” to a second predetermined amount of refrigerant, and “low” may map to a third predetermined amount of refrigerant. By “amount,” it is meant volume, weight, mass or any other characteristic that describes how much refrigerant is to be inserted or used with the package. It will also be understood that more than three amount levels (e.g., high, medium, and low) may be used. For example, an equation may be utilized that assigns points to input, and inputs entered into this equation, which yields an amount of refrigerant.
Returning to
It will be appreciated that “high,” “medium,” and “low” package strength structures may be defined according to a variety of different characteristics. For example, each of these characterizations may be associated with a predetermined package thickness, a package with a certain structure (e.g., honeycomb structure), or package constructed of a particular material (e.g., cardboard).

In one example, once the amount of refrigerant and amount of structural protection are determined, a table or matrix 600 maps these values to different groups of computer instructions that are executed by a machine to create the package. For instance, the instructions may create a package of certain dimensions that depend upon the height, length, width, and/or shape of the product. The package may have a wall thickness that depends upon the amount of protection (e.g., high, medium, or low) that is desired. The package may have an amount of refrigerant inserted that depends upon the amount of cooling needed. The instructions may be computer implemented instructions (e.g., computer code) that is utilized by a machine that actually creates the package.
It will be appreciated that instead of selecting a particular group of instructions, a predetermined package design may be determined. More specifically, once the amount of refrigerant and amount of structural protection for the package are determined, the table 600 may map directly to a predetermined package design, with the package having predetermined dimensions (e.g., height, length, width, and wall thickness) and having a predetermined amount of refrigerant in a predetermined distribution pattern.
As shown in the mapping table 600, package strengths 602, 604, and 606 and amount of refrigerants 608, 610, and 612 are mapped to different instructions (Instructions A, B, C, D, E, F, G, H, and I that are shown in the various cells of the table 600). For example, a high package strength 602 and a high amount of refrigerant 608 map to Instructions A. Once the instructions are selected, then these are executed to determine a pattern, design, or plan for the package. The plan is sent to a machine that constructs the package according to the design or plan. The instructions may use values of various parameters stored in memory, such as the parameters illustrated in

The air temperature 702 is the air temperature as measured by the delivery vehicle. The air temperature 702 may be obtained by sensors along a delivery route.
The delivery speed 704 is the delivery speed selected by the customer. For example, the delivery speed may be set to be fast, normal, or slow. Fast may mean overnight, normal may be 1-3 business days, and slow may mean greater than 3 business days in some examples.
The temperature requirement 706 may specify cold chain requirements for the product. For example, the product may be required to be kept at or below a predetermined temperature.
The product type 708 may be a specific product type such as frozen vegetables or cooled beverage. The dimensions 710 may be the physical dimensions of the product, including overall product dimensions. In some examples, the dimensions 710 are exact dimensions that include or define the product shape. The dimensions can be of any convenient measurement unit.

At step 802, product dimensions may be obtained. The product dimensions may be the length, width, and depth (or thickness) of the product. Additionally, the shape of the product may be considered as defined by the dimensions. For example, the dimensions may not only define straight lines, but non-rectangular shapes such as various types of curves. To take one example, the dimensions of a bottle of orange juice may be overall dimensions of the bottles (e.g., length, width, and thickness). However, in other aspects, the dimensions may specify the exact shape (e.g., including the curves) of the bottle. In other words, these dimensions would include overall dimensions, and also include dimensions and locations for curves in the bottle design, places where the thickness of the bottle varied (e.g., the bottle is thicker on bottom than on the top).
At step 804, a preliminary package design is obtained according to the product dimensions and with a honeycomb structure with a high thickness (HT). HT may be set to a predetermined value, for example, in inches or centimeters. In aspects, the HT value may be the high package thickness (HT) value 712. The preliminary package design may be of a standard shape or designed to fit the shape and contours of the product.
At step 806, the preliminary design is finalized by determining an amount and pattern of refrigerant (e.g., dry ice) to be inserted into the package structure. The refrigerant is inserted with a high density (HD) configuration. In aspects, the high density (HD) refrigerant value 718 of
The refrigerant may also be selectively spaced within the package based upon product type (e.g., according to the product type 708). For instance, a bottle of orange juice may be shipped and the refrigerant may be placed in the spaces of the honeycomb structure that are immediately adjacent to the bottle. In another example, the density of refrigerant may be varied in the package. For example, a first density of refrigerant may be deposited in areas or volumes immediately adjacent to the product, but a second (and lower) density deposited in areas or volumes that are not immediately adjacent to the product. The first and second densities may take on various values (including zero for the second density) as long as the first density is greater than the second density.
The result of completing step 806 is a final product design. The final product design may be in any electronic form such as a data structure, computer instructions, a script, or some combinations of these elements.

In addition, certain ones of the compartments serve to add/provide protection and/or refrigerant to benefit others of the compartments. For example, the compartment 1402 is completely surrounded by the other compartments 1404, 1406, 1408, 1410, and 1412. The compartments 1404, 1406, 1408, 1410, and 1412 provide protection for the contents of compartment 1402. Similarly, the other compartments 1404, 1406, 1408, 1410, and 1412 help cool the compartment 1402 by insulating the compartment 1402 and by adding to the refrigerant that directly surrounds the compartment 1402.
