Description
FIELD OF INVENTION

This invention relates to flexible packaging, and more particularly to a semi-rigid tray for transporting, storing, and dispensing ice. It also relates to the manufacture of handcrafted and artisanal ice for placement into the trays.


BACKGROUND

There is an increasing demand for handcrafted ice as a means of cooling various beverages, including carbonated soft-drinks, alcohol-containing drinks, cocktails, fruit beverages, functional drinks (i.e., energy drinks), sports drinks, coffee drinks, tea drinks, etc. Numerous commercial establishments, including bars, restaurants, hotels, and event spaces use handcrafted ice to enhance beverages served to customers. To this end, various shapes and forms of handcrafted ice have been developed, each variation having its own unique, desirable characteristics and behavior which can be utilized, for example, for a particular beverage or for a wide variety of beverages.


The process of manufacturing handcrafted ice in sufficient quantity to satisfy this demand is problematic. Part of the problem involves creating and maintaining the desirable characteristics and behavior of the handcrafted ice. These desirable features can be, for example, the clarity, shape, absence of cracks or blemishes, etc. of the ice. To ensure that these features are created and maintained can be an extremely labor and resource intensive process.


One approach to address these issues involves each individual commercial establishment forming, shaping, and maintaining the ice until served. However, this process is burdensome to the commercial establishment as it requires a significant expenditure of time and resources, which is either passed to the customer or internalized by the commercial establishment.


An alternative approach involves forming, shaping, and maintaining the ice by a third party, which specializes in manufacturing handcrafted ice. By off-loading the expensive process of manufacturing handcrafted ice, the commercial establishment can avoid spending unnecessary amounts of time and resources, while at the same time, have a reliable source of handcrafted ice. Additionally, by utilizing economies of scale, the third party specializing in manufacturing handcrafted ice can offer a product at reduced cost.


This alternative approach, however, creates additional logistical issues, as it is becomes necessary to transport the handcrafted ice from the third party to the commercial establishment. Ideally, the transportation of the handcrafted ice would be conducted in a manner in which all of the desirable characteristics and behavior of the handcrafted ice are not only maintained during transport but also until the ice is served to a customer.


SUMMARY

This specification describes technology relating to flexible packaging relating to transporting, storing, and dispensing ice. Implementations of the technology described herein comprise a flexible packaging tray capable of maintaining desirable features of ice during transportation and storage of the ice, and a method by which the device is used to transport and store the ice. Subject matter of the present application relates to subject matter in The Wiley Encyclopedia of Packaging Technology (Aaron L Brody & Kenneth S. Marsh, eds., 2nd ed. 1997), the entire content of which is hereby incorporated by reference herein; and more particularly reference is made to the section on Retortable Packaging (beginning at page 808).


The use of trays to form ice cubes is known. See, e.g., http://www.popsci.com/best-novelty-ice-molds-trays#page-24 (accessed Jul. 10, 2018). These types of trays are utilized by filling individual compartments of a tray with a liquid and placing the tray inside a refrigeration compartment until the liquid freezes and becomes a solid, resulting in an ice cube. The resulting shape of the ice cube is defined by the shape of the compartment of a particular tray. To remove the ice cube from its compartment, a force is applied to the tray. Removing the ice cube from the tray may require a significant force, as the frozen ice cube typically adheres to sides of the compartment during the freezing process. Moreover, by utilizing the trays and processes of the present invention for storage and transport after forming, as opposed utilizing the trays for formation, the nature of the ice cubes is significantly improved (such as, but not limited to, in terms of clarity, precision and uniformity of shape, and transportability).


The technology described in this specification fundamentally differs from known trays used to form ice cubes. The flexible packaging described herein is not utilized for the creation of ice cubes; rather, after an ice cube has been formed, the ice cube may be placed inside a compartment of a flexible packaging for transportation, storage, and/or dispensing of the ice. The shape of the ice cube is not defined by the shape of the compartment of the flexible packaging described in this specification. Instead, the shape and geometry of a compartment of the flexible packaging is selected to ensure that the ice cube maintains its desirable features.


An example embodiment of the present invention relates to a packaging assembly for transporting and storing ice, the packaging assembly including a tray having a base portion, and a plurality of compartments each formed on the base portion and configured to receive at least one piece of ice. In an example embodiment, each compartment includes an opening formed on the base portion, a bottom portion substantially parallel to the base portion, at least one sidewall having a first end and a second end, the at least one sidewall connecting the base portion to the bottom portion, and at least one volume strip formed in a respective at least one sidewall. In an example embodiment, the packaging assembly includes four compartments.


In an example embodiment, the at least one sidewall is formed as a circular frustum so that the first end has a diameter larger than a diameter of the second end. In an example embodiment, the second end of the sidewall is connected to the bottom portion at an angle that is greater than approximately 90° to facilitate release of the product from the tray. In an example embodiment, the second end of each sidewall is connected to the bottom portion at an angle that is 94°.


In example embodiment, each compartment includes four sidewalls so that each compartment is formed as at least one of a square frustum and a rectangle frustum. In an example embodiment, the second end of each sidewall is connected to the bottom portion at an angle that is greater than 90°. In an example embodiment, the second end of each sidewall is connected to the bottom portion at an angle that is 93°.


In an example embodiment, the tray and the plurality of compartments are formed as one-piece using a thermoplastic material. In an example embodiment, the thermoplastic material is a recyclable polypropylene.


In an example embodiment, the packaging assembly includes a cover covering the opening of the at least one compartment. In an example embodiment, the confer is configured to be removably attached to the base portion. In an example embodiment, the cover hermetically seals the at least one compartment via at least on heat seal.


In an example embodiment, each compartment includes a plurality of volume strips equally distributed on an outer surface of the respective sidewall. In an example embodiment, the volume strips are formed as parallel ridges extending from the first end of the sidewall to the second end of the sidewall and protrude outwardly from an outer surface of the sidewall.


Example embodiments of the present invention relate to a method for transporting and storing ice, the method comprising placing a shaped piece of ice into a compartment of a packaging assembly, the packaging in assembly including a tray having a base portion and a plurality of compartments, each formed on the base portion and configured to receive a respective shaped piece of ice. In an example embodiment, each compartment includes an opening formed on the base portion, a bottom portion substantially parallel to the base portion, at least one sidewall having a first end and a second end, the at least on side wall connecting the base portion to the bottom portion, and at least one volume strip formed in a respective at least one sidewall. In an example embodiment, the method further comprises sealing the at least one shaped piece of ice into the respective compartment of the packaging assembly using at least one cover, the at least one cover configured to be removably attached to the base portion.


In an example embodiment, the plurality of components are formed as at least one of a circular frustum, a square frustum, and a rectangle frustum. In an example embodiment, the at least one sidewall is formed as a circular frustum. In an example embodiment, the second end of the sidewall is connected to the bottom portion at an 94° angle. In an example embodiment, each compartment includes four side walls. In an example embodiment, the second end of each sidewall is connected to the bottom portion at an 93° angle.

Any embodiment of any of the disclosed compositions and/or methods can consist of or consist essentially of—rather than comprise/include/contain/have—any of the described elements and/or features and/or steps. Thus, in any of the claims, the term “consisting of” or “consisting essentially of” can be substituted for any of the open-ended linking verbs recited above, in order to change the scope of a given claim from what it would otherwise be using the open-ended linking verb.


The term “substantially” and its variations are defined as being largely but not necessarily wholly what is specified as understood by one of ordinary skill in the art, and in one non-limiting embodiment substantially refers to ranges within 10%, within 5%, within 1%, or within 0.5%.


The term “about” or “approximately” or “substantially unchanged” are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the terms are defined to be within 10%, preferably within 5%, more preferably within 1%, and most preferably within 0.5%.


The use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.”


As used in this specification and claim(s), the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”) or “containing” (and any form of containing, such as “contains” and “contain”) are inclusive or open-ended and do not exclude additional, unrecited elements or method steps.


Other objects, features, and advantages of the present invention will become apparent from the following detailed description. It should be understood, however, that the detailed description and the examples, while indicating specific embodiments of the invention, are given by way of illustration only. Additionally, it is contemplated that changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.


The drawings illustrate by way of example and not limitation. For the sake of brevity and clarity, every feature of a given structure is not always labeled in every figure in which that structure appears. Identical reference numbers do not necessarily indicate an identical structure. Rather, the same reference number may be used to indicate a similar feature or a feature with similar functionality, as may non-identical reference numbers. The figures are drawn to scale (unless otherwise noted), meaning the sizes of the depicted elements are accurate relative to each other for at least the embodiment depicted in the figures.


The ice that is placed into the trays of the present invention maybe of any origin, including “handcrafted,” artisanal, machine generated or shaped, lake- or spring-harvested, or from any other source, because the trays need not be associated with any particular manufacture or type of ice, and references to any ice source herein are meant to be illustrative and not limiting. Moreover, the composition of the ice is typically water but it need not be chemically pure (such that it could contain for instance minerals, flavorants, herbs, spices, etc.) It also will be understand that materials other than water may be used to make the subject ice (e.g., a solid, semi-solid, crystal, etc.).


In one embodiment of the invention, for instance, ice may be manufactured in large blocks. Those blocks may be slow-formed over a series of days. Once that ice is properly formed to an artisan's specification, the ice can be cut or chiseled or otherwise shaped by hand or by machine cuts along the three-dimensional primary axis directions (often called the x, y and z axis) in such a way as avoids chipping, air pockets, marring, disfiguration, or the like. Such shaping can be done e.g. by utilizing a variety of material handling equipment and platens, maintained to keep the ice in a frozen or near frozen state.

DETAILED DESCRIPTION

Various features and advantageous details are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. It should be understood, however, that the detailed description and the specific examples, while indicating embodiments, are given by way of illustration only, and not by way of limitation. Various substitutions, modifications, additions, and/or rearrangements will be apparent to those of ordinary skill in the art from this disclosure.


In the following description, numerous specific details are provided to provide a thorough understanding of the disclosed embodiments. One of ordinary skill in the relevant art will recognize, however, that the invention can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.


In an example embodiment, transportation and storage of handcrafted ice may be accomplished using a packaging assembly, as shown in FIGS. 1D, 2D, and 3D. Packaging assemblies include compartments for storing individual pieces of handcrafted ice that may be placed inside a compartment. Once placed inside a compartment, the handcrafted ice may be sealed inside the packaging assembly using a removable cover. For example, the cover may hermetically seal handcrafted ice inside packaging assembly. After transportation of the handcrafted ice is complete, the handcrafted ice may be stored inside packaging assembly until needed. Once needed, a portion of the removable cover covering a particular compartment may be removed so as to expose the handcrafted ice. A force may then be applied to remove the handcrafted ice. For example, a force may be applied to a bottom portion of the compartment which causes the handcrafted ice to dislodge from its compartment. Alternatively, a force may be applied to a bottom portion of the compartment which causes the sidewalls of the compartment to deform which causes the handcrafted ice to dislodge from its component.


For example, the packaging assembly may be designed as a disposable packaging assembly, so that once the handcrafted ice has been removed from the packaging assembly, the packaging assembly may be disposed of and/or recycled.


The rigidity of the packaging assembly and its compartments is selected to ensure that the desirable characteristics of the handcrafted ice, e.g., clarity, shape, absence of cracks, etc., are maintained during transportation, storage, and removal from the packaging assembly. For example, the composition of the packaging assembly is selected to ensure that the humidity, temperature, and transpiration of the handcrafted ice is controlled during transportation, storage, and removal. For example, a suitable plastic material may be used which acts as a barrier to maintain the humidity and temperature inside the compartment.


To facilitate the removal of the handcrafted ice from a compartment, the configuration of a compartment can be selected to ensure that the handcrafted ice is removed without causing damage to the ice. Sidewalls of the compartments may connect to a bottom portion of the compartment at a specific angle. For example, the sidewalls may connect to the bottom portion at an angle greater than 90°. For example, the sidewalls may connect to the bottom portion at an angle in the range of about 91° to about 99°, and preferably in a range of about 93° to about 94°. In this manner, when a force is applied to the bottom portion of the compartment, the handcrafted ice can easily be removed. Furthermore, when a force is applied to the bottom portion of the compartment that causes the sidewalls to deform, the handcrafted ice will not be damaged.


To protect the handcrafted ice during transportation, storage, and removal while still facilitating removal of the handcrafted ice, the bottom portions and corners of the compartments may be thicker than the sidewalls of the compartments. For example, the sidewall may have a thickness in a range of 1.0 mm to 2.0 mm, preferably in a range of 1.25 to 1.75; the portion that connects the sidewall to the bottom may have a thickness in a range of 4 mm to 6 mm, preferably in a range of 4.75 mm to 5.25 mm; and the bottom portion may have a thickness in a range of 4 mm to 6 mm, preferably in a range of 4.75 mm to 5.25 mm. For example, the sidewall may have a thickness of 1.5 mm; the portion that connects the sidewall to the bottom portion may be 5 mm; and the bottom portion may have a thickness of 5 mm.


To protect the handcrafted ice during transportation, storage, and removal and to facilitate the removal of the handcrafted ice, volume strips may be formed in the compartments. These volume strips may be formed in the sidewalls of the compartments and increase the rigidity of the compartment so as to facilitate removal of the handcrafted ice. Additionally, the volume strips enable and promote airflow around the surfaces of the handcrafted ice. Airflow around the handcrafted ice during transportation, storage, and removal is particularly advantageous, as it allows for enhanced humidity and transpiration control and prevents the handcrafted ice from adhering to the compartment, which facilitates removal of the handcrafted ice.


In addition to protecting the handcrafted ice during transportation, storage, and removal, forming equally spaced volume strips on the outer surface of the compartments saves costs associated with shipping the packaging assembly, as the volume strips facilitates and increases the amount of packaging assemblies that can be stacked on top of each other. For example, the volume strips may be formed as ridges formed on the outer surface of a compartment. For example, the volume strips may be equally spaced on the outer surface of the compartment.



FIGS. 1A-1E illustrate an example packaging assembly 100. FIG. 1A is a schematic top view of packaging assembly 100.
