FIELD OF THE INVENTION

The present invention relates generally to a template and container for providing protection and temperature-control for contents of the container.

BACKGROUND

When shipping fragile and/or temperature-sensitive items, consumers face a limited number of options for providing both insulation and/or cushioning to maintain and protect those items during shipping. For smaller shipments or mailings, paper envelopes lined with plastic bubble wrap are available, but provide limited protection and virtually no insulation. Rolls of bubble wrap may be utilized to wrap individual items, but wrapping individual items may be inconvenient, time-consuming, and costly, particularly for irregularly shaped items, and also may not provide adequate cushioning for very fragile items. Larger items are typically mailed in containers, such as corrugated boxes. However, the corrugated walls of such boxes provide very little cushioning and are not suitable for insulation without the addition of insulating material. Boxes or other types of containers lined with expanded polystyrene may be used to help maintain temperature, but expanded polystyrene provides very limited cushioning. Another major drawback to expanded polystyrene liners is that expanded polystyrene is not biodegradable in landfills.

Other options may include foam peanuts, which are used to fill empty spaces inside a container, or air pillows, which are plastic bags inflated with air that can be placed inside shipping containers. Both are relatively ineffective for very fragile or temperature-sensitive items. For instance, packing peanuts and air pillows provide little to no temperature-control and may not completely surround a fragile item, which may lead to breakage. Both are bulky to inventory, messy, inconvenient to deal with, and both may shift during transit, resulting in breakage of the shipped items.

When shipping temperature-sensitive items, such as perishable food products, foam peanuts and air pillows are not sufficient. Currently, insulation padding is used to insulate such food products from external temperatures. Generally, the insulation padding is made from at least two pieces and must be placed inside a constructed box. Often, this process must be done by hand because the padding inserts must be placed with precision to ensure a proper thermal or protective fit. In addition to the padding, temperature-control elements such as ice packs, gel packs, or phase change materials may be used to cool or heat the interior of the container when shipping perishable items. The installation of such components by hand to an existing container may add considerable cost to the production of insulated containers.

Accordingly, a need exists in the art for a container and container template having a one-piece design that provides both improved cushioning and insulation for shipping fragile or temperature-sensitive items. Furthermore, a need exists in the art for heating or cooling elements to be incorporated into or in conjunction with insulated padding material of the container and container template.

SUMMARY

In accordance with the present disclosure, a one-piece cushioning and insulating container and an insulation template for making the container are provided. The template may be constructed of a plurality of materials and is configured for foldably forming a three-dimensional container having an insulated and cushioned interior for shipping items inside the container that are fragile and/or temperature-sensitive. The template is designed to provide a completely enclosed space that is cushioned and insulated on all sides. The dimensions of the template may be adjusted to create containers of varying dimensions. For instance, templates of different sizes may correspond to standard sized cardboard boxes used by the United States Postal Service or other freight carriers, such as FedEx or UPS, for shipping items.

The insulation template comprises a generally flat case blank that folds to form an external container body and an insulating member secured to one side of the case blank, preferably by an adhesive that secures the insulating member in a fixed position on the case blank. The case blank is adapted to fold along fold lines arranged to form a three-dimensional container having interior surfaces, and the insulating member is arranged so that it covers all interior surfaces of the three-dimensional container. Thus, the case blank is configured to transform from a generally flat configuration into a three-dimensional container, and the insulating member is configured to form a completely closed and insulated interior of the container once the case blank has been folded into a container. In this way, the container of the present disclosure does not require the container to be placed in a three-dimensional configuration before insulation material is installed therein. The case blank has a plurality of adhesive tabs configured to secure adjacent side walls of the container to each other when forming the container from the case blank and insulating member.

The case blank comprises a unitary piece of material, which is preferably corrugated cardboard, that is divided into sections each corresponding to a top, a bottom, and four sides, respectively, of the container. In a preferred embodiment, the case blank has the shape of a cross and is symmetrical in shape. One or both sides of the case blank may be laminated to facilitate securing the insulating member to the case blank with an adhesive. The laminate may be biodegradable. Boundaries of each section of the case blank may be defined by cuts or miters in the case blank, which help to facilitate folding of the case blank into a three-dimensional container. Thus, the section boundaries form a living hinge by which sections of the case blank may be folded to form the three-dimensional container.

The insulating member comprises a soft, flexible material that can be readily compressed and deformed to enable the insulating member to conform to the shape formed by the case blank and to provide cushioning and insulation for items placed within the container. The insulating member preferably comprises cotton fibers to act as a cushioning agent. In one embodiment, the insulating member may comprise a bi-component fiber including cotton fibers and another type of fiber, such as polyester fibers or polyethylene fibers, which may be present in an amount sufficient to hold the cotton fiber together in order to form a distinct, defined insulating member that may be secured to the case blank as a unit of insulation. The fibers may also contain biodegradable additives. The thickness of the insulating member may vary depending on the dimensions of the container and the desired amount of cushioning or insulation to be provided therein. In a preferred embodiment, the insulating member is about one-quarter inch to two inches thick when in a decompressed state. The thickness of the insulating member may also be increased to provide additional cushioning or insulation, as desired.

The insulating member is preferably encapsulated and sealed within a flexible plastic material such as a bag or a film. The encapsulating material ensures that the insulation fibers are contained and isolated from the shipped contents in the interior of the container and also facilitates securing the insulating member to the case blank prior to folding the insulation template, which is a single unit that includes both the case blank and the insulating member, into a three-dimensional container. The insulating member may optionally have angled miters formed in the member at locations corresponding to the boundaries between sections of the case blank. The miters are shaped to form miter joints when the case blank is folded into a three-dimensional container in order to provide complete coverage of the entire interior of the container with cushioning and insulation.

The insulating member may have heating or cooling elements contained within the encapsulating material. In one embodiment, gel packs may be utilized. In another embodiment, phase change material may be utilized. In this embodiment, it is preferable, but not required, that the phase change material be incorporated directly into the insulation. In this way, the phase change material may come in the form of packs and may serve multiple purposes of insulation, padding, and heating or cooling. Similarly, gel packs and other heating or cooling elements may be secured directly to the case blank to function in a similar manner. In yet another embodiment, the case blank may be covered partially in phase change material, gel packs, or an insulating member.

In accordance with the present disclosure, a one-piece cushioning and insulating container 30 and an insulation template 10 for making the container are provided. The template 10 may be constructed of a plurality of materials and is configured for foldably forming a three-dimensional container 30 having an insulated and cushioned interior for shipping items inside the container that are fragile and/or temperature-sensitive. The template 10 is designed to provide a completely enclosed space that is cushioned and insulated on all sides. The dimensions of the template 10 may be adjusted to create containers 30 of varying dimensions. For instance, templates of different sizes may correspond to standard sized cardboard boxes used by the United States Postal Service or other freight carriers, such as FedEx or UPS, for shipping items.

As shown in FIG. 1, the insulation template 10 comprises a generally flat case blank 40 that folds to form an external container body and an insulating member 12 secured to one side of the case blank 40, preferably by an adhesive 18 that secures the insulating member 12 in a fixed position on the case blank 40. FIG. 4 illustrates the case blank 40, and FIG. 1 illustrates the insulating member 12 secured to one side of the case blank 40 with adhesive 18. The case blank 40 is adapted to fold along fold lines 41 arranged to form a three-dimensional container 30 having interior surfaces, and the insulating member 12 is arranged so that it covers all interior surfaces of the three-dimensional container 30, as shown in FIG. 3. FIG. 4 shows a top side of the case blank 40, the surface of which forms the interior surfaces of the container 30 when folded into a container 30. The opposite side, or bottom side, of the case blank 40 forms the exterior surfaces of the container 30 when folded. As shown in FIG. 1, the insulating member 12 is secured to the top side of the case blank 40. Thus, the case blank 40 is configured to transform from a generally flat configuration, as shown in FIG. 4, into a three-dimensional container 30, and the insulating member 12 is configured to form a completely closed and insulated interior of the container 30 once the case blank 40 has been folded into a container 30, as shown in FIG. 3. In this way, the container 30 of the present disclosure does not require the container to be placed in a three-dimensional configuration before insulation material 12 is installed therein. The insulating member 12 may be secured to the flat case blank 40 and the combination of case blank 40 and insulating member 12, which form insulation template 10, may be folded simultaneously to form the container 30 for shipping items. As used herein, a “one-piece” container 30 refers to a container formed from a template that includes both a case blank and an insulating member secured together such that the container may be formed by folding the case blank and insulating member simultaneously as a single unit.

The case blank 40 comprises a unitary piece of material, which is preferably corrugated cardboard, that is divided into sections each corresponding to a top, a bottom, and four sides, respectively, of the container 30. Alternatively, the case blank 40 may be constructed of materials including, but not limited to, plastics, papers, cardboards, metals, polymers, or any other material suitable for manufacturing a container for shipping items within the container. In a preferred embodiment, as shown in FIG. 4, the case blank 40 has the shape of a cross and is symmetrical in shape. One or both sides of the case blank 40 may be laminated to facilitate securing the insulating member 12 to the case blank 40 with an adhesive 18. The laminate may be biodegradable. Boundaries of each section of the case blank 40 may be defined by cuts 41 or miters in the case blank, which help to facilitate folding of the case blank 40 into a three-dimensional container 30. Thus, the section boundaries form a living hinge by which sections of the case blank 40 may be folded to form the three-dimensional container 30.

The insulating member 12 comprises a soft, flexible material that can be readily compressed and deformed to enable the insulating member 12 to conform to the shape formed by the case blank 40 and to provide cushioning and insulation for items placed within the container 30. The insulating member 12 preferably comprises cotton fibers to act as a cushioning agent. In one embodiment, the insulating member 12 may comprise a bi-component fiber including cotton fibers and another type of fiber, such as polyester fibers or polyethylene fibers, which may be present in an amount sufficient to hold the cotton fiber together in order to form a distinct, defined insulating member that may be secured to the case blank as a unit of insulation. The fibers may also contain biodegradable additives. The insulating member may comprise other materials suitable for use as insulating materials, including, but not limited to, cotton, polyester, recycled fabrics, polymers, and the like. The thickness of the insulating member 12 may vary depending on the dimensions of the container 30 and the desired amount of cushioning or insulation to be provided therein. In a preferred embodiment, the insulating member 12 is about one-quarter inch to two inches thick when in a decompressed state, as shown in FIG. 2. The thickness of the insulating member 12 may also be increased to provide additional cushioning or insulation, as desired.

The insulating member 12 is preferably encapsulated and sealed within a flexible plastic material 19, as best seen in FIG. 2, which may be a plastic film or bag that is shaped to fit within the three-dimensional container 30 in a configuration in which the insulating member covers all interior surfaces of the container. The encapsulating material 19 ensures that the insulation fibers are contained and isolated from the shipped contents in the interior of the container 30 and also facilitates securing the insulating member 12 to the case blank 40 prior to folding the insulation template 10, which is a single unit that includes both the case blank 40 and the insulating member 12, into a three-dimensional container 30. The insulating member 12 is preferably a single member having a shape corresponding to the shape of the case blank 40, though the insulating member may alternatively comprise more than one member individually secured to the case blank 40 in appropriate locations so that the combination of insulating members completely covers all interior surfaces of the container 30, including corners.

As shown in FIG. 2, the insulating member 12 is preferably secured to the case blank 40 by adhesive 18. In a preferred embodiment, the adhesive 18 is a fugitive glue or similar type of adhesive that has sufficient strength to keep the insulating member 12 secured to the case blank 40 during normal use and shipping, but allows manual separation of the insulating member 12 from the case blank 40. Thus, the use of a fugitive glue may facilitate recycling of both the case blank 40 and the insulating member 12 by allowing easy removal of adhesive from these components. The case blank 40 has a plurality of adhesive tabs 16 configured to secure adjacent side walls of the container 30 to each other when forming the container from the case blank 40 and insulating member 12. A fugitive glue adhesive is preferably also utilized on the adhesive tabs 16 to facilitate forming the container 30 from the case blank 40. The fugitive glue may be removed from the tabs 16 to break the three-dimensional container 30 down back into a flat case blank 40 for recycling after use.

To form a three-dimensional container 30, a generally flat case blank 40 and an insulating member 12 are provided. The case blank 40 is adapted to fold along fold lines 41 that form boundaries between sections of the case blank 40, as shown in FIG. 4. Section 45 forms the bottom of the container 30, and sections 43 and 46 form side walls of the container. Sections 47 and 48 form the top, or lid, of the container. The fold lines 41 may be defined by cuts, perforations, miters, or any similar structural features that facilitate folding of the case blank. The insulating member 12 is then positioned on the top side of the case blank 40 and secured to the case blank, preferably with an adhesive 18, which is preferably a fugitive glue. The adhesive 18 may be applied to the case blank 40 or to the insulating member 12. The case blank 40 and insulating member 12 should be of corresponding sizes, as shown in FIG. 1, for constructing the container 30 so that all interior surfaces are covered by the insulating member 12.

The insulating member 12 also has sections corresponding to the sections of the case blank 40. As shown in FIG. 1, the insulating member 12 has fold lines 14 at which the insulating member is folded with the case blank after the insulating member 12 has been secured to the case blank 40 with adhesive 18. The fold lines 14 may be defined by cuts, perforations, miters, or any similar structural features that facilitate folding of the insulating member. Alternatively, the fold lines 14 of the flexible insulating member 12 may function as living hinges without any type of cuts to the insulating member. When the insulating member 12 is secured to the case blank 40 in a flattened state, as shown in FIG. 2, section 12a of the insulating member covers section 45 of the case blank 40. The two sections 12b cover side wall sections 43, and the two sections 12c cover side wall sections 46. Sections 12d insulate and cushion the interior surface of the top of the container 30 and cover sections 48 of the case blank.

To form the container 30 from the generally flat insulation template 10, sections 46 of the case blank 40 and sections 12c of the insulating member 12 are first simultaneously folded upward along fold lines 41 and 14, respectively, at a 90-degree angle to bottom section 45. These are the sections that do not have the adhesive tabs 16 attached thereto. Next, sections 43 of the case blank 40 and sections 12b of the insulating member 12 are simultaneously folded upward along fold lines 41 and 14, respectively, at a 90-degree angle. Adhesive tabs 16, to which adhesive has been applied, are then folded to secure adjacent side walls 43 and 46 to each other, as best seen in FIG. 3. The adhesive tabs 16 ensure structural stability of the container 30 by providing vertical support along each corner of the container. For increased strength, additional securing elements may be utilized in addition to the adhesive tabs 16, which may include, but are not limited to, glues, epoxies, staples, brads, nails, screws, or any similar securing elements known in the art.

In a preferred embodiment, the top of the container 30, or lid, is formed by a plurality of case blank sections 47 and 48. As shown in FIGS. 1 and 3, opposing sections 48 are preferably covered by insulating member sections 12d, and opposing sections 47 are not covered by the insulating member 12. FIG. 3 illustrates the container 30 with the top open for loading items into or unloading items from the container. To close the lid of the container, opposing sections 48, including insulating member sections 12d, may be folded over toward each other so that the two opposing sections 12d completely cover the top section of the container. Opposing sections 47 may then be folded over toward each other on top of sections 48 to provide added strength to the lid for the container. These sections forming the top of the container may be sealed closed for shipping by tape or similar means.

The method of forming the three-dimensional container 30 may be performed manually or by automated machinery adapted for this purpose. By encapsulating the insulation material within a plastic bag or film to form a unit of insulation material, the insulating member 12 may be handled by automated machinery for placement on the case blank 40, which allows an accurate fit of the insulating member 12 on the case blank 40 and within the container 30. This provides effective cushioning and insulation within the container while eliminating potential defects in the placement of the insulating member 12 due to workmanship, which may cause gaps in insulation and cushioning within the container.

FIGS. 5 and 6 illustrate an alternative embodiment in which the insulating member 12 has angled miters 60 formed in the insulating member 12 at locations corresponding to the boundaries 41 between sections of the case blank 40. The miters 60 are preferably formed at approximately 45-degree angles and are shaped to form miter joints with opposing mitered edges 60 pressing against each other when the case blank 40 is folded into a three-dimensional container 30. Thus, the miters 60 may help to provide complete coverage of the entire interior of the container with cushioning and insulation. The mitering forms boundaries between the sections 12a-12d of the insulating member 12. The rectangular sets of dashed lines shown in FIG. 5 illustrate the individual sections, and the spaces shown between rectangular sections indicate the gaps 65 formed by the mitered edges 60, as shown in FIG. 6. The forming of the miters 60 may be performed during production of the insulating member 12 before securing the insulating member to the case blank to produce the container 30. The utilization of miters 60 may facilitate the folding of the insulating member 12 along fold lines, which may facilitate the process of forming the container by helping the insulating member 12 to conform to the shape of the container as the case blank 40 is folded to form the container 30. As shown in FIG. 5, the opposing edges of sections 12d are not mitered because these sections 12d fold toward each other to form the lid of the container.

As shown in FIG. 7, the insulating member 12 may optionally have temperature control elements 70, which may be heating or cooling elements, contained within the encapsulating material 19. In one embodiment, gel packs may be utilized. In another embodiment, phase change material may be utilized. In this embodiment, it is preferable, but not required, that the phase change material be incorporated directly into the insulation. In this way, the phase change material may come in the form of packs and may serve multiple purposes of insulation, padding, and heating or cooling. Similarly, gel packs and other heating or cooling elements may alternatively be secured directly to the case blank 40 to function in a similar manner. In yet another embodiment, the case blank may be covered partially in phase change material, gel packs, or an insulating member.

As used herein, phase change materials (PCMs) include, but are not limited to, water-based materials, salt hydrates, paraffins, and vegetable-based materials. Water-based ice and gel packs are suitable for keeping materials cold around 0° C. These low-cost devices perform well, are nontoxic, non-flammable, environmentally friendly, and easy to use. Salt hydrates consist of inorganic salts and water. Their melt point temperatures may range between 15° C. and 80° C. Some of the advantages of salt hydrates are low material costs, high latent heat storage capacity, precise melting point, high thermal conductivity, and inflammability. Paraffins, typically, are derived from petroleum and have a waxy consistency at room temperature. Their melt point temperatures generally range between −8° C. and 40° C. They have generally good thermal storage capacity and are proven to freeze without supercooling. They also have the advantage of chemical stability over many heating and freezing cycles. They are non-corrosive and are compatible with most encapsulating materials. Bio-based PCMs are organic compounds derived from animal fat and plant oils. Their melt point temperatures range between −40° C. and 151° C. The most common bio-based PCMs are derived from fatty acids and have higher efficiency than salt hydrates and petroleum-based phase change materials. It is understood that PCMs known to one of skill in the art, now or in the future, may be utilized as disclosed herein and fall within the scope of the inventive subject matter.

These PCMs, as described herein, may be attached to or incorporated directly into the case blank 40. In this way, the PCMs may be activated, either chemically or physically, and immediately packed for shipping. For example, case blanks utilizing gel packs may be stored in a refrigerated area along with goods being stored for shipment. In this way, the gel packs will cool to the shipping temperature in the same facility in which the container 30 is loaded and will not require additional energy for cooling the packs. In another embodiment, a user may chemically set a PCM for a specific temperature range. Upon setting the temperature range of the material, the case blank may be immediately folded into a box, loaded, and shipped.

As described herein, in a preferred embodiment, the case blank 40 and the insulating member 12 both generally have the shape of a cross that is symmetrical in two axes at a right angle to each other—a horizontal and a vertical axis in the orientation shown in FIG. 1. In alternative embodiments, the case blank and insulating member may have other shapes suitable for forming a three-dimensional container 30. One such embodiment is illustrated in FIG. 8. In this embodiment, the case blank 40 has a lowercase “t” shape with an insulating member having mitered sections. Sections 82 form the four sides of the container 30, and section 84 forms a lid for the container. This embodiment is similar to previously described embodiments except that the lid of the container is defined by a single section 84 that is attached to a side section and may be folded over after folding the side sections 82 and securing adjacent side sections 82 to each other with the adhesive tabs 16. Section 84 has an additional adhesive tab 86 that may be used to secure the lid closed by securing the tab 86 to an exterior surface of the opposing side section 82. Once section 84 is folded over to close the container 30, additional sections 87 attached to the case blank 40 may be folded over on top of section 84 to add strength to the lid. Opposing sections 87 may be secured in place with tape or similar means.

The devices and methods shown and described herein are exemplary. Though certain characteristics of the present inventions are described above, the description is illustrative only. It is understood that versions of the invention may come in different forms and embodiments. Additionally, it is understood that one of skill in the art would appreciate these various forms and embodiments as falling within the scope of the invention as disclosed herein.
