Aspects and implementations of the present disclosure are generally directed to apparatuses made with expanding foam and methods of manufacturing apparatuses with expanding foam, more specifically to organizational apparatuses made with plant-based expanding foam.
The market for organization products, e.g., bins, baskets, totes, etc., lack options that that are durably made for years of use, lightweight, easily washed, and manufactured with sustainable materials and processes. Consumers seek products that have a quality design with durable and sustainable materials in an effort to extend the longevity of those products and curb the throwaway plastic culture that is damaging our planet. These same consumers are interested in products that are made from sustainable materials in an effort to support products that help to reduce carbon-dioxide emissions.
Current market options include injection molded plastic bins, woven baskets, and cut and sewn fabric bins. Molded plastic bins have a cheap-looking aesthetic and do not consider the environment in their design as they are produced through injection molding virgin plastic. Woven baskets are not durable and users often throw them out after they become used or dirty. Woven baskets are also expensive, take excessive human labor to assemble, and are made with cheap labor because of this. Woven baskets are also very difficult to clean thoroughly and deteriorate when damp or wet. Fabric bins are often lined internally with plastic sheets—giving them the necessary structure and stiffness—but this process makes cleaning the fabric tedious and the products are not durable because they rely on laminating plastic to fabric with glue. Fabric bins that do not have internal structural parts (e.g., bins made of felt) are flimsy and do not have the structure to withstand daily use. Felt is also a non-woven material that is difficult to clean because of its loose fibers.
The present disclosure provides a new design, material, and process of manufacturing an organizational apparatus, e.g., an organizational bin, made from expanding-foam. In some examples the expanding-foam is a plant-based Ethylene-vinyl Acetate (EVA) foam. In some examples, the bin includes four walls and a base forming an interior cavity that is configured to receive items to be organized, stored, or transported, e.g., shoes, or dirty or wet items. The organizational bin is made through a minimal-waste process, where the entire product is formed in a single injection-molding step. The raw bio-based materials used in the process are mixed in the desired formulation, the bin is molded in a crosslinking expansion process, and finally the bin is cooled on a shaping jig, which helps to set its final shape and dimensions. The EVA expansion-foam process creates a bin that is sealed on all its surfaces to protect the foam from the environment. This feature makes it washable, durable, and improves its resistance to tearing. The mass of the raw foam material is carefully controlled during molding to minimize any waste. Any excess EVA foam that is not crosslinked can be recycled. Additionally, the expansion-foam process allows for the manufacture of bins in a wide range of colors and texture finishes, and allows logos and branding information to be directly molded into the surface of the bin without additional manufacturing steps.
In one example, an organizational bin made of expansion-foam material is provided, the organizational bin including a base and a plurality of walls, wherein each of the plurality of walls includes a first end and a second end, wherein each of the first ends of the walls are integrally formed with the base, thereby forming a cavity between the plurality of walls; and wherein the base and the plurality of walls comprise the expansion-foam material.
In one aspect, the expansion-foam material is bio-based Ethylene-vinyl Acetate (EVA) expansion-foam made from sugarcane.
In one aspect, the base includes an inside surface in communication with the cavity, and an outside surface, the base further including a ledge at a boundary between outside surface of the base and each of the plurality of walls.
In one aspect, the plurality of walls includes at least four walls such that the cavity substantially forms a cube.
In one aspect, the base includes an inside surface in communication with the cavity, and an outside surface, the base further including a ledge at the boundary between the outside surface of the base and each of the four walls, such that the ledge is arranged to contact a surface beneath the organizational bin and a recess of the outside surface of the base is not in contact with the surface beneath the organization bin.
In an aspect, the expansion-foam material comprises from about 65% to about 70% bio-based ethylene-vinyl acetate resin material.
In an aspect, the expansion-foam material comprises from about 2% to about 8% natural cellulose fiber.
In an aspect, the expansion-foam material comprises from about 15% to about 20% polyethylene.
In an aspect, the expansion-foam material comprises from about 1% to about 3% zinc oxide.

In an aspect, the expansion-foam material has a density of about 0.3 g/cm3.
In an aspect, the expansion-foam material has a durometer reading of between 65 and 75 using an Asker-C durometer.
In another example, a process of manufacturing an organizational bin is provided. The method comprises: providing a raw bio-based ethylene-vinyl acetate expansion-foam from sugar cane in a carbon-negative process; mixing the bio-based ethylene-vinyl acetate expansion-foam with at least one of cellulose fibers, polyethylene, assorted pigments, a coupling agent, a blowing agent, and a crosslinking agent to form an ethylene-vinyl acetate expansion-foam material; molding the ethylene-vinyl acetate expansion-foam material to form an organizational bin component; pre-cooling the organizational bin component for a period of time; placing the organizational bin on a shaping jig to form an organizational bin; and finishing the cooling process.
In an aspect, the period of time is about 30 seconds.

These and other aspects of the various embodiments will be apparent from and elucidated with reference to the embodiment(s) described hereinafter.
In the drawings, like reference characters generally refer to the same parts throughout the different views. Also, the drawings are not necessarily to scale, emphasis instead generally being placed upon illustrating the principles of the various embodiments.
The present disclosure provides a new design, material, and process of manufacturing an organizational apparatus, e.g., an organizational bin, made from expanding-foam. In some examples the expanding-foam is a plant-based Ethylene-vinyl Acetate (EVA) foam. In some examples, the bin includes four walls and a base forming an interior cavity that is configured to receive items to be organized, stored, or transported, e.g., shoes, or dirty or wet items. The following description should be read in view of
As shown, organizational bin 100 includes a base 102 and a plurality of walls, e.g., walls 104A-104B (collectively referred to herein as “walls 104” or “plurality of walls 104”). Each wall of the plurality of walls 104 includes a first end, e.g., first ends 106A-106D (collectively referred to herein as “first end 106” or “first ends 106”) and a second end, e.g., second ends 108A-108D (collectively referred to herein as “second end 108” or “second ends 108”). The dimension of each wall 104 between first end 106 and second end 108 and along a line that intersects both the first end 106 and second end 108 will be referred to as the length of the wall 104 or the height of the wall 104, while the dimension between the first end 106 and the second end 108 along a line substantially orthogonal to the length of the wall 104 will be referred to as the width of the wall 104. As will be discussed below, in one example embodiment, the organizational bin 100 is intended to be formed using a single injection molding process, and therefore, base 102 and walls 104 can be formed as a single integral body. For example, each second end 108 of the walls 104 can be integrally formed with the base 102 to form a single unitary body.
Additionally, in the example illustrated in
As shown in
As can be seen in
As set forth above, base 102 and walls 104 can be formed as a single unitary body. It should be appreciated that base 102 and walls 104 can be made from expanding-foam (also referred to as “expansion-foam”). The material formulation for the expanding-foam used for the present disclosure includes: 65%-70% bio-based EVA resin material; 2%-8% natural cellulose fiber; 15%-20% Polyethylene, 1%-3% Zinc Oxide; and 1%-5% assorted pigments. The material discussed herein and formed using the processes discussed below have an approximate density of 0.3 g/cm3 and have a durometer reading of between 65-75 (unitless) using an Asker-C durometer. In some examples, the bio-based EVA resin material is manufactured from plant-based renewable materials, e.g., sugar cane. The use of sugar cane in this process results in a carbon-negative impact on the environment.
The process of manufacturing the organization bin includes: sourcing the raw bio-based EVA expansion-foam from sugar cane (carbon-negative process); mixing the bio-based EVA expansion-foam with cellulose fibers, polyethylene, assorted pigments, and any necessary coupling agent, blowing agent, and crosslinking agent; molding the bio-based EVA expansion-foam in an EVA expansion-foam molding process to form an organizational bin component; pre-cooling the organizational bin component (e.g., for 30 seconds); turning the organizational bin component upside down and placing it on a shaping jig to form an organizational bin and finishing the cooling process. The step of pre-cooling can include placing the organizational bin component on a table or other cool surface for approximately 30 seconds before moving to the shaping jig. Thus pre-cooling step is utilized to ensure that the organizational bin shrinks evenly on its top edge (i.e., proximate first end 106) and allows for better control of the final cooled flatness of that edge. This process produces an organizational bin that is completely sealed such that the entire exposed surface area is water-proof.
The apparatus and processes outlined herein provide distinct advantages over present offerings. First, the rigid base 102 with ledge 118 keeps the bottom of the organizational bin 100 sitting flat on surface S and increases overall stiffness of the bin. The enhanced stiffness provided by base 102 and ledge 118 also ensures that the bin always returns to its original shape and sits flatly on surface S. Also, the expansion-foam gives a novel aesthetic and feel to a common product that has not been treated in this way before. The foam is stiff enough to keep its shape and strength, yet pliable, so that it protects the items it carries in transit. This material makes it easier to transport. One example use case of the organizer bin is to transport and organize items that regularly move between the house and the car. The flexible construction makes it possible to use the bin in multiple types of settings and use cases, inside and outside the house. Additionally, the use of two handles, i.e., first and second handle apertures 112A-112B that are molded into the walls 104 of the bin, make carrying the bin simple and ergonomic. As mentioned above, the bio-based EVA expansion-foam used is made from sugarcane in a carbon-negative process. By reducing oil-based plastic materials, the processes herein also reduce the production of toxic and harmful pollutants to the environment. The EVA expansion-foam described herein is also nontoxic and resistant to standard household chemicals and UV rays. Furthermore, the process used to mold the expansion-foam allows for the integration of logos or branding directly molded to the surface of the walls 104 or base 102 of the bin without additional manufacturing steps.
As mentioned above, the completely sealed surface makes the bin easy to clean as it is impenetrable to water. Research has shown that current bins on the market are often thrown away when they get dirty because they are very hard to clean. By making the bin easily washable, it encourages users to keep using the bin for a longer product lifetime over traditional bins or baskets.
Furthermore, the bio-based EVA expansion-foam material is a good insulator.
Therefore, the organizational bin 100 described and manufactured using the processes herein can be used to keep items cold or hot depending on need. For example, the expansion-foam will keep ice and/or drinks cold for longer than standard plastic bins. This allows users to use the bin for carrying drinks or food in any setting including outdoor activities, like camping, going to the beach, or going to the pool.
All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.
The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases.
