## Background
BACKGROUND OF THE INVENTION
The subject matter described herein relates generally to the packaging of products. More particularly, the subject matter described herein relates to a modular container assembly for packaging a plurality of products.
Container systems are known to contain at least one product within a cavity. Examples of products contained with such known container systems include food products, cosmetics, adhesives, and medical/surgical tools. Typically, container systems are uniquely configured for each storage and/or application requirement. Meeting such unique storage or application requirements can be expensive in terms of capital investment for tooling to fabricate the container as well as drive inventory costs.
With at least some known container system applications, once a product is stored therein, the system may be subjected to further processing. For example, known container systems may be filled with a first product, and then subsequently heated, cooled, sealed, and/or stored to further process and/or treat the first product. When such known container systems are filled with a second product, the second product mixes with the first product and, thus, is subject to similar processes, treatments, and/or environments as the first product, which may not be acceptable.
To separate one product from another product, at least some known container systems include a plurality of sidewalls that define a plurality of cavities, wherein each of the cavities contains a separate product. Each sidewall typically is formed from the same material as the other sidewalls, and therefore, the material used to form the sidewalls is selected so as to accommodate the processing requirements for all the products stored in the container system. As a result, if one of the sidewalls requires use of more expensive material than the other sidewalls, even the other sidewalls are fabricated from the more expensive material, which adversely impacts the overall cost of the container system.
In addition to material selection, in at least some applications, the shape of at least one sidewall of the container system is independent of the shape of the other sidewalls. Known systems generally do not provide for selection of independent sidewall shapes, which is a constraint on the types of products that may be stored as well as product combinations.
BRIEF DESCRIPTION OF THE INVENTION
In one aspect, a modular container assembly is provided. The modular container assembly includes a frame and a first portable container. The frame includes a plurality of edge portions that define a plurality of openings. The first container includes a sidewall that defines a cavity. The first container is sealable at a rim portion of the sidewall to retain a product within the cavity. The first container is configured to fit within a first opening of the plurality of openings such that the rim portion is removably coupled to a first edge portion of the plurality of edge portions.
In another aspect, a method is provided for packaging a product in a modular container assembly. The modular container assembly includes a frame and a first portable container. The frame includes a plurality of edge portions that define a plurality of openings. The first container includes a sidewall that defines a cavity. The sidewall includes a rim portion.

As shown in at least FIG. 4, at least a segment of rim portion 124 includes a first flange 136 and/or a second flange 138. In the exemplary embodiment, first flange 136 and/or second flange 138 facilitate removably coupling container 102 to frame 104.
In the exemplary embodiment, first flange 136 extends about at least a portion of cavity 122. More particularly, in the exemplary embodiment, first flange 136 extends about a perimeter of rim portion 124. Alternatively, a plurality of first flanges 136 may extend intermittently about the perimeter of rim portion 124. In the exemplary embodiment, first flange 136 includes a container back drafted wall 140, described in further detail below.
In the exemplary embodiment, first flange 136 is positioned at a first height 142 (shown in FIG. 3) above base 118. In the exemplary embodiment, first height 142 is less than approximately 2.4 in. Particularly, in the exemplary embodiment, first height 142 is between approximately 0.5 in. and approximately 1.6 in. First height 142 may be any height that enables container 102 to function as described herein.
Moreover, in the exemplary embodiment, first flange 136 extends outwardly a first distance 144 from sidewall 120. In the exemplary embodiment, first distance 144 is less than approximately 0.3 in. Particularly, in the exemplary embodiment, first distance 144 is less than approximately 0.2 in. First distance 144 may be any distance that enables container 102 to function as described herein.

In the exemplary embodiment, second flange 138 enables positioning at least a segment of rim portion 124 above at least a portion of frame 104.
In the exemplary embodiment, container 102 is coverable with a lid (not shown). More specifically, in the exemplary embodiment, the lid is releasably coupleable to container 102 for positioning the lid relative to container 102 between an open configuration and a closed configuration of container 102. In the open configuration, the lid is at least partially removed from container 102 to provide access to cavity 122. In the closed configuration, the lid is coupled to container 102 to substantially enclose cavity 122.
In the exemplary embodiment, frame 104 includes a top surface 150 including a frame edge portion 152 (shown in FIG. 2) that defines opening 106. In the exemplary embodiment, at least a segment of frame edge portion 152 includes an undercut 154, or a notch, that is configured to engage with first flange 136 to facilitate removably coupling container 102 to frame 104. In the exemplary embodiment, undercut 154 is substantially complementary to first flange 136. More specifically, in the exemplary embodiment, undercut 154 includes a frame back drafted wall 156 that is substantially complementary to container back drafted wall 140 of first flange 136.
A resistance of separation is associated with an interface 158 between first flange 136 and undercut 154. More specifically, the resistance of separation is associated with an amount of force required to couple container 102 to frame 104 and/or decouple container 102 from frame 104. For example, increasing the resistance of separation associated with interface 158 generally requires additional force to couple container 102 to frame 104 and/or decouple container 102 from frame 104. Conversely, decreasing the resistance of separation associated with interface 158 generally requires less force to couple container 102 to frame 104 and/or decouple container 102 from frame 104.
In the exemplary embodiment, the resistance of separation is controlled by adjusting interface 158. In the exemplary embodiment, the resistance of separation is controlled by adjusting a configuration of container back drafted wall 140 and/or frame back drafted wall 156. More specifically, in the exemplary embodiment, a back draft angle 160, a height 162, and/or a lock feature radius 164 (shown in at least FIG. 5) of container back drafted wall 140 and/or frame back drafted wall 156 is adjusted to control the resistance of separation between container 102 and frame 104. Moreover, in the exemplary embodiment, a gap or distance 166 (shown in at least FIG. 5) between container back drafted wall 140 and frame back drafted wall 156 is adjusted to control the resistance of separation between container 102 and frame 104.
In the exemplary embodiment, modular container assembly 100 includes containers 102 having varying configurations including back draft angles 160, heights 162, and/or lock feature radii 164, wherein each container 102 has a respective resistance of separation associated with its particular configuration. Moreover, in the exemplary embodiment, modular container assembly 100 includes a plurality of frames 104 having varying configurations including back draft angles 160, heights 162, and/or lock feature radii 164, wherein each frame 104 has a respective resistance of separation associated with its particular configuration.
In the exemplary embodiment, container 102 and/or frame 104 include any combination of first flanges 136 and/or undercuts 154 shown in FIGS. 4-7 to control the resistance of separation between container 102 and frame 104. For example, back draft angle 160 and/or height 162 may be increased to facilitate increasing the resistance of separation between container 102 and frame 104. Conversely, back draft angle 160 and/or height 162 may be decreased to facilitate decreasing the resistance of separation between container 102 and frame 104. In the exemplary embodiment, providing container back drafted wall 140 and/or frame back drafted wall 156 with a lock feature radius 164 may facilitate decreasing the resistance of separation between container 102 and frame 104. Moreover, in the exemplary embodiment, increasing distance 166 between container back drafted wall 140 and frame back drafted wall 156 may facilitate decreasing the resistance of separation between container 102 and frame 104.
Particularly, as shown in FIG. 4, first flange 136 is configured to align substantially flush with undercut 154 when container 102 is coupled to frame 104. Moreover, as shown in FIG. 5, first flange 136 and undercut 154 have substantially complementary configurations, but distance 166 is provided between container back drafted wall 140 and frame back drafted wall 156 when container 102 is coupled to frame 104. Further, as shown in FIG. 6, first flange 136 and undercut 154 have varying back draft angles 160 such that a gap 168 is provided between container back drafted wall 140 and frame back drafted wall 156 when container 102 is coupled to frame 104. Furthermore, as shown in FIG. 7, first flange 136 and undercut 154 have substantially complementary configurations, but an interference fit 170 is provided between container back drafted wall 140 and frame back drafted wall 156 when container 102 is coupled to frame 104.
FIG. 8 illustrates an alternative flange-undercut interface 158. In the exemplary embodiment, at least a segment of rim portion 124 includes first flange 136 and/or second flange 138. In the exemplary embodiment, first flange 136 includes container back drafted wall 140, and second flange 138 extends outwardly to define an undercut 172 therebelow. In the exemplary embodiment, at least a segment of frame edge portion 152 is sized and/or configured to fit within undercut 172 to facilitate removably coupling container 102 to frame 104.
As shown in at least FIG. 9, at least a portion of top surface 150 includes a step 172 to facilitate decoupling container 102 from frame 104. In the exemplary embodiment, step 172 extends about at least a portion of opening 106. More particularly, in the exemplary embodiment, step 172 extends about a perimeter of opening 106. Alternatively, step 172 may extend intermittently about the perimeter of opening 106.
Particularly, in the exemplary embodiment, at least a portion of second flange 138 extends over at least a portion of step 172 to provide an overhang 174 such that a gap 176 is formed between second flange 138 and step 172 when container 102 is coupled to frame 104. In the exemplary embodiment, a size of gap 176 is controlled by adjusting height 162 of container back drafted wall 140, height 162 of frame back draft wall 156 and/or a depth 178 of step 172 relative to top surface 150.
In the exemplary embodiment, container 102 and/or frame 104 are fabricated from at least one suitable material including, without limitation, polyethylene terephthalate (PET), high-impact polystyrene (HIP), polypropylene (PP), copolymer polypropylene (COPP), polyvinyl chloride (PVC), oriented polystyrene (OPS), a copolyester (PETG), and/or an acrylonitrile (BAREX). Notably, each individual container 102 and/or frame 104 may be produced from any material or combination of materials that are suitable for the container contents, processing requirements, and/or storage requirements. For example, in one embodiment, containers 102 are decoupled from frame 104, such that containers 102 may be sorted based on a recyclability of the material and/or combination of materials used to fabricate each container 102. Moreover, in such an embodiment, containers 102 and/or frame 104 may be selected for use based on a recyclability of the material and/or combination of materials used to fabricate containers 102 and/or frame 104.
In one embodiment, container 102 and/or frame 104 includes a hang tab 180 (shown in FIG. 2) configured to cooperate with a shelf display peg, a butterfly hook, a wire peg hook, and/or a merchandising strip, such that container 102 and/or frame 104 is displayable in a display environment. In such an embodiment, the hang tab includes an opening and/or a hook sized and/or oriented to receive the shelf display peg, butterfly hook, wire peg hook, and/or merchandising strip.
In one embodiment, container 102 and/or frame 104 may be formed in an injection molding and/or thermoforming process used for producing parts from thermoplastic or thermosetting plastic materials. Particularly, at least one suitable material may be selected to fabricate container 102 depending on a product retained within cavity 122, processing needs for the product, a barrier requirement, and/or a shelf stabilization requirement. It is understood, however, that container 102 and/or frame 104 may be constructed of different materials from each other without departing from the scope of this invention.
FIG. 10 illustrates a method 200 for packaging a plurality of products (not shown) using modular container assembly 100. During operation, in the exemplary embodiment, modular container assembly 100 is provided 202.
In the exemplary embodiment, each container 102 is selected 204 based on the product retained within cavity 122, the material used to fabricate container 102, a desired processing of the product, and/or a desired resistance of separation between container 102 and frame 104.
In the exemplary embodiment, container 102 retains 206 at least one product within cavity 122 independent of the other containers 102. Moreover, in the exemplary embodiment, container 102 is processed 208 independent of the other containers 102. More specifically, in the exemplary embodiment, container 102 is processed to process product retained within cavity 122. In the exemplary embodiment, processing includes at least partially filling cavity 122 with at least one product, heating container 102, cooling container 102, sealing container 102, and/or storing container 102.
In the exemplary embodiment, container 102 is removably coupled to frame 104 independent of the other containers 102. More specifically, in the exemplary embodiment, container 102 is received 210 within opening 106 such that first flange 136 engages 212 with undercut 154. Moreover, in the exemplary embodiment, second flange 138 engages 214 with top surface 150 such that second flange 138 extends above step 172 to provide gap 176 therebetween.
