Description

CONTAINER WITH INTEGRATED PROTECTION FEATURE

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U S Provisional Patent Application No. 62/608,950, filed on December 21, 2017, the entirety of which is incorporated by reference herein.

FIELD OF THE INVENTION

[0002] The present invention relates generally to the field of packaging, and specifically to protective packaged containers used to dispense a fluid or gel.

BACKGROUND OF THE INVENTION

[0003] Various containers are known in the art for the retention and exhibition of fluids or gels such as cleaning products, fabric care products or oral care products. Such containers are typically formed with a primary packaging having a shape and size selected to minimize weight and/or outer profile so as to maximize the quantity of containers receivable in a shipping carton. However, this primary packaging sacrifices structural integrity for other factors such as weight, size and aesthetics. Thus, in order to ship said container, they must he provided with a secondary or tertiary packaging to protect the container during transport. In some cases, the primary packaging is loaded into a shipping carton (secondary packaging) and the shipping carton is provided with a means to prevent further damage to the container during transport (tertiary packaging). For example, a cushioning material (e.g , loose-fill styrofoam packing material or "packing peanuts", air-filled sacs, etc.) is inserted into the shipping carton to prevent free movement of the container during transport. However, these packaging systems are cumbersome and require the addition of additional packaging materials at various stages of transport, therefore increasing the manpower needed to transport goods to a consumer, creating extra steps to be completed by the shipper and any intermediary parties (e.g., third-party seller), and increasing the overall cost of shipping the container.

[0004] Further, in a situation where only a small quantify of containers is to be shipped, the containers are often loaded in a large shipping box, thereby using valuable space in a transport vehicle and reducing the quantity of items that can be shipped together. [0005] There is a need for a container which is configured to withstand forced applied thereto during transport (e.g., e-commerce) while preventing the need for repackaging a container during transport

BR!EF SUMMARY

[0006] The present invention is directed to a container comprises a container body having a cavity for receiving a product therein and a lid sealing an opening to said cavity, the container body having a front surface, back surface, first sidewall and second sidewall, and a first bumper attached to the first sidewall of the container body, the first bumper configured to absorb forces applied to the container, wherein the first bumper comprises a first engagement mechanism configured to locking!y engage a second engagement mechanism located on the container body.

DETAILED DESCRIPTION

[0042] The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

[0043] The description of illustrative embodiments according to principles of the present invention is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description. In the description of embodiments of the invention disclosed herein, any reference to direction or orientation is merely intended for convenience of description and is not in tended in any way to limit the scope of the present invention. Relative terms such as "lower," "upper," "horizontal," "vertical," "above," "below," "top" and "bottom" as well as derivative thereof (e.g., "horizontally," "downwardly," "upwardly," etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are for convenience of description only and do not require that the apparatus be constructed or operated in a particular orientation unless explicitly indicated as such. Terms such as "attached," "affixed," "connected," "coupled," "interconnected," and similar refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise. Moreover, the features and benefits of the invention are illustrated by reference to the exemplified embodiments. Accordingly, the invention expressly should not be limited to such exemplary embodiments illustrating non- limiting combinations of features that may exist alone or in other combinations of features; the scope of the invention being defined by the claims appended hereto.

[0044] Exemplary embodiments of the present invention will now be described with respect to a packaging system for a fluid or fluid-like material including, but not limited to a cleaning product, water solution, skin-care product, fabric care product, a hair care product and/or oral care product. However, other embodiments of the present invention may be used to store and dispense any suitable type of fluid and the invention is expressly not limited to any particular fluidic material alone.

[0045] A container according to the present invention is formed with protective features in the form of bumpers on an outer surface thereof, the protective features being configured to permit transport of the container without the need for secondary packaging. Whereas conventional containers {e.g., containers housing oral care products such as toothpaste or mouthwash; containers housing home care products such as detergent, softener, cleaning solution, dish soap; etc.) are packaged within a shipping carton including a cushioning material therein to prevent container breakage and/or leakage during transport, the containers described herein are configured to permit shipping without the use of any secondary packaging. In formulating the containers described herein, extensive research was done to determine the forces and loads applied to items during transport from a manufacturing facility to an end user. The containers described herein are capable of withstanding forces from dropping, radial compression (e.g., when loaded in a delivery vehicle with other packages), etc. in particular, the containers described herein are provided with features configured to absorb and insulate the interior of the container from external forces. Any of the protective features described herein may be formed integral to the container or may be removably attached thereto. Further, any of the containers described herein may be provided with any combination of the protective features described herein.

The exemplary containers described herein are further configured to receive a shipping label directly thereonto. The shipping labels may be removable or permanently attached to the container. The exemplary container described herein may be shipped by itself without any secondary packaging or with any plurality of additional containers. Further, the exemplary container may be shipped to a brick and mortar retail store and sold with the exemplary protective bumpers provided thereon.

[0046] The containers described herein may be formed with integrally formed bumpers which are permanently attached thereto. For example, the container may be manufactured with the bumper provided thereon (e.g., via injection stretch blow molding, extrusion blow molding, etc.), as those of skill in the art will understand. In another embodiment, the bumper may be formed separately from the container body and attached thereto during a manufacturing step via one or more of an adhesive, welding, a mechanical attachment (e.g., tongue and groove, snap-fit, friction-fit, keyed fit, etc.) or any other method of attachment known to those of skill in the art. Any of the container bodies described herein may be modified to include one or more of the bumpers described in any of the embodiments described herein to provide added strength to specific portions of the container body. Further, various features of the containers described herein may be combined with one another without deviating from the scope of the invention. As a non-limiting example, the shape of the container body may be substantially rectangular as in FIGS. 1A-8C, frusto-conical as in FIGS. 9A-9C, cylindrical, elliptical, or any other shape in an embodiment where a cylindrical container body is used, a front surface of the container body may correspond to a portion of the container outer body oriented in first direction. Side surfaces of the container body may be offset from the front surface by approximately 90 degrees and a back surface of the container body may correspond to a surface located opposi te the front surface and separated from the side surfaces by approximately 90 degrees. Bumpers, as described herein may be attached to a cylindrical container body in the same manner described herein with respect to rectangular container bodies. Further, any of the container bodies may be modified to include any of the lids described herein, necked or otherwise. Additionally, any of the protective bumpers described herein may be formed with a solid or hollow configuration.

[0047] The integrally formed bumper containers described herein may be formed of one or more of polyolefins (polypropylenes, low, medium and high density po!yethylenes), which may be formed via extrusion blow molding), polyethylene terephthalate ("PET") (made via injection stretch blow molding) and elastomeric materials, and any combination of the above. Such containers adhere to limitations of the blow molding process and can thus be manufactured faster than multi-component pieces and are fully recyclable. Non-integrally formed containers, which comprise separately formed bumpers, provide the added advantage that a number of different materials may be used to provide a desired

combination of strength, resilience, weight and aesthetic appeal to the completed container. The container body of the separately formed containers may be formed of the same materials discussed above. The bumpers of the separately formed containers may be formed of extruded resins, polyolefins (po!ypropy!enes, low, medium and high density polyethylenes) (made via extrusion blow molding), PET (made via injection stretch blow molding), elastomeric materials, rubbers, molded or extruded cellulose (e.g. paper pulp), and any combination of the above.

[0048] FIGS. 1A-1B depict a container 100 for the storage of a fluidic material. The container comprises a unitary container body 102 formed of a polymer and extending along a longitudinal axis 101. A lid 104 is provided on an upper surface 106 of the container 100, the lid 104 selectively sealing an opening (not shown) formed in said upper surface 106 to provide access to the contents of the container. In a preferred embodiment, the lid 104 is coupled to the container 100 by a hinge mechanism, wherein the hinge may be integrally formed with the lid. The lid 104 may alternatively be separable from the container 100. In a preferred embodiment, the container body 102 is substantially rectangular and comprises rounded edges to minimize damage thereto when impacted. This shape further facilitates case packing and is robust enough to minimize the need for secondary packaging. The upper surface 106 further comprises a recessed portion 108 adjacent the opening (not shown). The recessed neck of the container body 102 further comprises a retention ring (not shown) which engages a corresponding retention ring on the lid 104The recessed portion 108 is longitudinally offset from the upper surface 106 by a predetermined depth selected so that, when the lid 104 is positioned thereover, the lid 104 lies flush with or below the upper surface 106. This configuration reduces forces applied to the lid during transport and therefore reduces the risk of the lid becoming accidentally detached from the container. The lid 104 further comprises a protrusion or tab 110 provided on a gripping surface thereof to enhance the ability of a user to grip and open the lid. The lid 104 may alternatively be coupled to the container 100 by a screw engagement, friction-fit or another attachment means known in the art. An additional securement may optionally be provided over the lid 104 (e.g., removable sealing mechanism such as a sticker, etc.). At least an outer portion of the lid 104 is rectangular to prevent the lid 104 from rotating and changing orientation once received over the container body 102.

[0049] The container comprises a front surface 112, lower surface 114 opposite the upper surface 106, opposing side surfaces 116, 118 and a back surface 120. One or both of the front and back surfaces 112, 120 may comprise a label or decorative item indicative of, for example, the contents of the package. For example, the front surface 112 may include a label indicating the contents of the package while the back surface 120 may remain blank or may include instructions on product use, instructions for use, or any other information that is conventionally provided on a package for end-consumer reference. The back surface 120 is further adapted to receive a shipping label (not shown) thereon. The back surface 120 may be provided with a surface treatment {e.g., a high gloss finish) that permits the shipping label to be removed therefrom by an end recipient without tearing, damaging or otherwise inhibiting access to the instruction label. Alternatively, the instruction label may not be obstructed by the shipping label. In yet another embodiment, the instruction label may be included in a separate booklet (not shown) shipped with the container 100. Alternatively, the shipping label may be a dual layer sticker wherein a first clear layer (not shown) is permanently attached to the back surface 120 by a permanent or seml-permanent adhesive and a second removable layer is provided thereover, the second removable layer including shipping information including, but not limited to, sender details, recipient details, order number, QR code, etc.

[0050] An optional beveled surface 107 may be provided between the upper surface 106 and the front surface 112. Corresponding beveled surfaces may be provided between the front surface 112 and lower surface 114, between the back surface and the upper surface 106 and/or between the back surface 120 and the lower surface 114.

[0051] The container 100 further comprises bumpers in the form of first and second bellows 122, 124 separating the side surfaces 116, 118 respectively from the front and back surfaces 112, 120. The bellows 122, 124 are formed as an accordioned layer of the container adapted to be compressible when subjected to an outside force exceeding a predetermined minimum. In a preferred embodiment, the bellows 122, 124 are biased to a resting configuration in which adjacent folds 124 are in a partially compressed configuration and are capable of being radially compressed as indicated by arrows A, as depicted in FIG. IB, or radially expanded (not shown). The folds 124 are oriented parallel to a longitudinal axis of the container 100. As seen in FIG. 2, the folds are configured such that, when radially compressed, the folds 124 remain flush with an outer profile of the container 100, substantially aligned with the front and back surfaces 112, 120. That is, a height of the bellows 122, 124 does not increase beyond a height H of the container 100 when radially compressed. This configuration is selected to minimize an expansion of the height of the container 100 when the bellows is compressed.

Alternatively, the bellows may be configured to extend beyond the original height H, length L and/or depth D when compressed to increase dimensions of the container 100.

[0052] In a preferred embodiment, the bellows 122, 124 are adapted to be radially compressible by a predetermined distance. For example, the bellows 122, 124 may be configured such that a length of the container 100 moves from a length L in a biased resting configuration (i.e., when no external forces are applied to the container) to a radially compressed configuration which may be a percentage of the length L. This configuration has been selected to permit the container to deform under external forces which would otherwise result in a fracture or breakage of the container. This configuration has also been selected to strengthen the container 100 while avoiding the addition of any unnecessary bulk to the container, which would result in increased manufacturing and shipping costs. The result is a container 100 which exhibits substantially increased rigidity when compared to prior art containers while minimizing production and shipping costs. Through extensive testing, it has been found that the container 100 is capable of withstanding forces applied during shipping (e.g., from a warehouse, to a shipping carrier and ultimately to delivery address such as a home or business) and obviates the need for packaging within an additional shipping box. That is, whereas conventional containers must be packaged within a separate shipping box with additional padding provided therein, the exemplary container 100 described herein is capable of being shipped on its own without the use of any additional shipping containers.

[0053] For example, if a force exceeding a predetermined minimum force is applied to any of the upper, lower, front or back surfaces, the bellows may radially expand to absorb compressive forces applied to the container and prevent a fracture or rupture of the container. The container 100 may be biased to return to the resting configuration of FIG. 1 upon removal of the extraneous force applied thereto. It is noted that although the bellows 122, 124 is depicted with six folds 126, any number of folds may be used without deviating from the scope of the invention (e.g., one or more folds). The bellows 122, 124 may be identical to one another or may include variable numbers of folds. [0054] The bellows 122, 124 are formed integrally with the container 100 such that an inner wall of the bellows defines an inner surface of the container in direct contact with a fluid, gel or other material contained therein. In such configurations, the container body is filled with a quantity of fluid to allow for compression of the bellows 122, 124 without causing overflow. Alternatively, the bellows 122, 124 may be formed separately from the container and attached thereto via adhesive, sealing/welding other mechanical as discussed earlier, wherein the bellows 122, 124 are hollow. In one embodiment, the bellows may be slidably receivable over the container body via, for example, a tongue and groove mechanism as in FIGS. 9A-9B. Optionally, additional sidewalls (not shown) may be provided in the non integral bellows configuration to restrict the flow of the fluid, gel or other material therewithin.

[0055] FIGS. 2A-2B depict a container 200 according to another embodiment. The container 200 is substantially similar to the container 100 except as discussed below. Similar to the container 100, the container 200 comprises a unitary outer body 202, lid 204, upper surface 206, recessed portion 208, front surface 212, lower surface 214, side surfaces 216, 218 and back surface 220. Unlike the container 100 which is formed with two bellows 122, 124, the container 200 comprises a single bellows 222 oriented along the width W of the container 200. The bellows 222 comprises a plurality of folds 226 extending parallel to a longitudinal axis of the container and configured to permit radial compression of the container along its width.

[0056] FIGS. 3A-3B depict a container 300 according to another embodiment. The container 300 comprises a container body 302 having a lid 304, upper surface 306, recessed portion 308, front surface 312, lower surface 314, side surfaces 316, 318 and back surface 320. The front and back surfaces 312, 320 each comprise a pair of longitudinal grooves 322, 324 extending parallel to a longitudinal axis of the container 300. The grooves 322, 324 are formed with a C-shaped cross-section defining a channel 326 and an opening 328 open to said channel. As depicted in the partial cross-sectional view of FIG. 3B, the channel 326 has a substantially circular cross-section, although any other shape may be used with the condition that a width of the channel 326 is greater than a width of the opening 328. For example, the channel 326 cross-section may be triangular, trapezoidal, oval, diamond-shaped or oblong. The grooves 322, 324 may be provided on both the front surface 312 and back surface 320 to, for example, ensure proper alignment of the bumper 330 over the container. Alternatively, any number of grooves may be provided on any of the front, back or side surfaces of the container. [0057] The container 300 further comprises a bumper 330 receivable thereover. The bumper 330 may be permanently attached to the container body 302 or be removable therefrom. The bumper 330 comprises an upper wall 332 and a pair of side walls 334, 336 extending orthogonal to the upper wall 332. A pair of extensions 333 is provided on either side of an opening 335 extending through the upper wall 332. The extensions 333 are configure to protect the lid 304 when it is received through the opening 335. Preferably, the extensions 333 are configured to be flush with or have greater dimensions than the lid 304 when the lid is seated within opening 335. The extensions 333 may be solid in construction or hollow. Flaps 338 extend substantially orthogonally from each of the side walls 334, 336 and flaps 340 extend orthogonally from the upper wall 332 over the front and back surfaces 312, 320 of the container 300. A juncture between the upper wall 332 and the side walls 334, 336 and flaps 338, 340 comprises an optional pleated portion 342 configured to conform to the shape of the container body.

[0058] Although the bumper 330 of FIG. 3A extends over only a portion of container body 302, the bumper 330 may be modified to cover any portion or all of the container body.

[0059] The bumper 330 comprises a plurality of lips 344 provided on an inner surface of the flaps 338, the lips configured to be s!idingly received within the grooves 322, 324. The lips 344 may be configured to frictiona!ly engage the grooves 322, 324 to lock the cover in place over the container. Optionally, an additional temporary locking mechanism such as a locking tab or adhesive may be provided on one or both of the cover and the container to lock the cover in place during transport. The lips 344 may be formed of a rubber or other compressible material to enhance grip and prevent premature detachment. Alternatively, the bumper may lock over the container body 302 via one or more of a friction fit, adhesive, boss, snap-fit, stake-on, uni-directional ratchet, or any alternative mechanical locking means known to those of skill in the art.

[0060] The bumper 330 is adapted to be received over the container during, for example, transport. In a preferred embodiment, the bumper 330 is receivable over the container 300 in two configurations. In a first preferable configuration for transport, the upper wall 332 is covers the lid 304, protecting the lid 304 from inadvertently opening. Once delivered to an end user, the cover may be removed and discarded or, may be inserted over the lower end of the container such that the upper wall 332 covers the lower surface 314 of the container. The flaps 338, 340 provide added protection to the container 300 when the bumper 330 is received thereover.

[0061] FIG. 4A depicts a container 400 having a body 402 and cover 430 formed substantially similar to the container 300 and bumper 330, except as discussed below. The container body 402 is formed with a neck that is not recessed into its body. Rather, a lid 404 is provided on a neck 406 that extends longitudinally out of the container body 402 and defines a shoulder 407. Although the lid 404 is depicted with a tapered rectangular cross-section, any other lid shape can be used without deviating from the scope of the invention. A rectangular, elliptical or oblong lid is preferred to avoid rotation thereof over the container body but any other shape may be used without deviating from the scope of the invention.

[0062] The cover 430 is a two-piece cover having upper and lower portions 428, 432 configured to encase both the upper and lower surfaces of the container body 402. A first, lower cover portion 432 has a rigid construction and includes first, second and third wail sections 434, 436, 438. An inner surface 440 of the first cover portion 432 is corrugated, including a series of raised ridges 442 separated from one another by a series of grooves 444. Ridges 442 and grooves 444 on the first and third surfaces 434, 438 extend parallel to a longitudinal axis 401 of the container body 402. The lower cover portion 432 includes the above-described corrugations on an inner surface while an inner surface of the upper portion 428may be substantially smooth, including no ridges or grooves. This configuration reduces manufacturing costs as well as the overall profile of the container 400.

[0063] The exemplary corrugated configuration of the cover 430 has been selected to impart a predetermined strength to the container 400. Specifically, the size, depth and orientation of ridges 442 and grooves 444 has been selected to withstand compressive forces applied thereto - e.g., during shipping from a manufacturing facility to an end user, without the use of any extraneous padding or additional protective means. In particular, the corrugated design is configured to reduce and/or eliminate deformation of the container under out of plane compression (i.e., wherein radially compressive forces are applied to any outer planar surface of the container), in -plane lateral forces, transverse shear stress, etc.

[0064] In a preferred embodiment, the corrugated cover 430 is capable of withstanding a

predetermined shear stress of on the upper surface 431 and lower surface 433, where: F

^{Tl =} A

wherein, t₅ = shear stress;

F = force applied to upper surface 431 and lower surface 433; and

A = area of one of the upper surface 431 and the lower surface 433.

[0065] Side surfaces 435, 437 are capable of withstanding at least a shear stress t₂. Front and back surfaces 434, 438 are capable of withstanding at least a predetermined shear stress t₃.
