The present inventions relate to packaging systems, for example, including retention packaging systems incorporating a retention frame and resilient sheet member for retaining an article to be packaged or shipped within a container and containers including integrated cushioning features that can optionally be used in combination with retention devices.
Protective packaging devices are often used to protect goods from shocks and impacts during shipping or transportation. For example, when transporting articles that are relatively fragile, it is often desirable to cushion the article inside a box to protect the article from a physical impact against the inner walls of the box which could be caused by shocks imparted to the box during loading, transit, and unloading.
In most cases, some additional structure is used to keep the article from moving uncontrollably within the box. Such additional structures include paper or plastic packing material, structured plastic foams, foam-filled cushions, and the like. Ideally, the article to be packaged is suspended or retained within the box so as to be spaced from at least some of the walls of the box, thus protecting the article from other foreign objects which may impact or compromise the outer walls of the box.
U.S. Pat. No. 11,124,348 discloses a number of inventions related to retention and suspension structures which incorporate a sheet of resilient material heat sealed to corrugated cardboard. In the designs disclosed in the U.S. Pat. No. 11,124,348 patent, the resilient sheet is attached to a piece of foldable cardboard so that the resilient material is tensioned by folding the cardboard, and for example, the resilient sheet material is stretched around the article.
At least one of the inventions disclosed herein includes the realization that certain additional efficiencies can be obtained in a packaging process incorporating structures that can retain a retention packaging element in a secured position without the need for applying additional adhesives or securing devices such as tape. For example, during certain packaging processes, an open box is moved along a packaging processing line. During the process, an article to be packaged, for example, a delicate object, and a retention device can be used to resiliently maintain the object against another surface. However, such a resilient retention device tends to bounce or move while the container remains open, if another securing device is not engaged with it.
Thus, if the container were moved along a packaging line after the object is in place in the open container with an unsecured retention device, the object and retention device could shift undesirably and thus require realignment in a later stage in the packaging process. For example, the packaging process may include the addition of other objects, such as instruction manuals, charging cables, or other devices that are not contained in the same segregated area within the box the first object.
Thus, an aspect of at least one of the inventions disclosed herein includes the realization that packaging assembly can include a retention frame with a resilient member and wherein the frame is configured to form a secured fitment with the container, without the need for additional glue or tape or other securing devices to be applied thereto. For example, in some embodiments, the retention frame can be sized to form an interference fit with the interior of the container. Thus, using such a system, an object to be packaged can be placed in the container and then the retention frame can be placed over the object and moved into the container until a secure interference fit has been generated between the frame and the container. With such a configuration, the container, while remaining in an open condition, can be moved along a packaging line and additional objects can be placed in the box, for example, on top of the secured retention device. This allows the packaging process to proceed efficiently without concern for the object and retention device from being dislodged or shifting during the remainder of the packaging process, until the box is finally closed.
In some embodiments, a retention assembly and the container are configured to include a latching function. For example, the container can include a projecting surface and the retention assembly can include a portion with a surface opposing the projecting surface wherein the portion is biased into a position so as to generate an alignment between the opposing surfaces. Thus, as the retention frame is pushed into the container, the biased portion can flex around the projecting surface and then snap into place into abutting alignment, thereby retaining the retention frame in place, in a latched condition. In some embodiments, the container or the retention frame can include finger grasps configured to allow a user to pull the biased portion out of alignment, for removing the retention frame from the container and thereby accessing the object.
Another aspect of at least one of the inventions disclosed herein includes the realization that a bottom portion of a shipping container, such as a carboard box, can include additional features for creating cushioning structures. For example, some shipping containers, such as cardboard boxes, include a bottom wall formed of “minor flaps” which are folded inwardly and form an inner bottom surface of the container and outer “major flaps” that are folded to form an outer bottom wall of a cardboard box. An aspect of at least one of the inventions disclosed herein includes the realization that minor flaps can be provided with additional structures beyond that of known typical minor flap designs, that can form deployable cushioning structures.
For example, in some embodiments, a foldable container member can include a bottom wall portion with minor flap members having extended lengths and are preconfigured with folding lines to allow for preferential folding into an enlarged structure that can serve as a cushioning structure on the inner bottom wall of the container. In some embodiments, the additional material can be monolithically formed with the minor flaps. As such, the cushioning structures can be conveniently formed with the material, such as cardboard, forming the container itself.
In some embodiments, the minor flaps include a sufficient amount of additional material to create an enclosed space within a bottom wall structure of the container. In some configurations, the enclosed space includes an upper wall spaced away from a lower wall with an air gap therebetween. Additionally, in some embodiments, a portion of the minor flap can be attached or attachable to an inner sidewall of the container, so as to achieve a predetermined or desired configuration of the minor flap cushioning structure.
Additionally, in some embodiments, a container having a deployable cushioning structure on an inner bottom wall can be used in conjunction with any of the retention member assemblies described above.

The resilient member 114 can be made from any type of resilient material. In some embodiments, the resilient member 114 can be formed of one or more layers of polyethylene films, low density polyethylene (LDPE), polyurethane, TPU, or virtually any polymer, or plastic film. Density of the layers used for the resilient member 114 can be varied to provide the desired retention characteristics such as overall strength, resiliency, and vibrational response. Preferably, the density of the material used to form the resilient member 114 is chosen such that the resilient member 114 is substantially resilient when used to package a desired article 104 and subject to the loads and accelerations commonly accommodated for typical shipping applications. Such loads and accelerations are well known in the art.
The frame member 112 can be made from any kind of rigid material. In the environment of use of packaging, plain and corrugated cardboard is often appropriate. Thus, in some embodiments, the frame member 112 can be made from a corrugated structure which would normally have an inner layer, an outer layer, and an internal, corrugated structure, including, but not limited to, “A-flute,” “B-flute,” “C-flute,” “D-flute,” and “E-flute” cardboard. Other types of corrugated structures using cardboard packaging similar devices can also be used
In the illustrated embodiment, the frame member 112 is generally rectangular or square. Additionally, the frame member 112 can include a generally continuous outer frame portion 116 which can be considered as including end sections 118, 120 and side sections 122, 124.
The frame member 112 can also optionally include deflectable petal portions that can be configured to be effectively resiliently bendable with a bias towards a flat configuration, such as the configuration illustrated in
Optionally, the frame member can include additional fold lines for enhancing the progressive deflection of the petal portions 130, 132, 134, 136. For example, but without limitation, member 112 can include additional fold lines 137, 138, 140, and 142. These additional fold lines 137, 138, 140, 142 provide an additional segmentation and articulation of the petal portions 130, 132, 134, 136 providing a more progressive deflection and resilient effect in use.
The resilient member 114 can be attached to the frame member 112 in any known manner. For example, the resilient member 114 can be heat sealed, stapled, or glued to the frame member 112, or the resilient member 114 can be provided with pockets extending over a portion of the frame member 112. In the illustrated embodiment, ends of the resilient member 112 are secured to the end portions 118, 120 of the frame member 112 at secured portions 144, 146, respectively.
The frame member 112 can have overall dimensions, such as a length 113 and a width 115, that a configured to cooperate with the container 150 to provide optional advantages.

The container 150 can also include a top 162 that can be considered as being formed by a plurality of foldable panels. In the illustrated embodiment, top 162 includes foldable panels 164, 166, 168, and 170. The bottom 152 can also be made up of a plurality of foldable panels referred to generally as panels 172.
The illustrated embodiment of the container 150 can be a conventional design.
The container 150 can be considered as including an internal cavity having an inner length 74 and an inner width 176. As noted above, optionally, the outer dimensions 113, 115 of the retention member 110 can be sized so as to form an advantageous engagement with the container 150. For example, in some embodiments, one or both of the length and width 113, 115 of the retention member 110 can be approximately the same as or slightly larger than the inner length and width 174, 176 of the container 150. For example, the length and width 113, 115 could be one to three millimeters larger than the length and width 174, 176 of the container 150. Other dimensions can also be used to provide the desired amount of engagement.
With such a configuration, the retention member 110 can be used to capture an article 102 between the resilient member 114 and the bottom 152 of the container 150. For example, as shown in

The top panel 364, 368 can be subdivided into three folding panels for example, the top panel 364 is subdivided into portions 364A, 364B and 364C. Similarly, the top panel 368 is subdivided into panel portions 368A, 368B, and 368C. Ultimately, the free edges of portions 364C and 368C will form the protruding portions 355 and 359, respectively.
Additionally, optionally, the portion 364C can include a clearance notch 365 and the panel portion 368C can include a similar or the same clearance notch 369. Clearance notches 365, 369 can provide clearance for a user to insert their finger to remove the retention member 310 from the container 350, described in greater detail below. An anchor tab 351 can extend from one end of the panel for purposes of forming the container 350 into an assembled state, such as that illustrated in
With reference to
Additionally, in order to orient the protruding portion 355 in the operative orientation, the portion 364B is folded onto the panel portion 364A and the portion 364C is partly overlapped with a portion of side wall 354.

Optionally, fold lines 321, 323 can be configured to provide an outward bias of the panels 341, 345. This can be accomplished by using one of many known techniques for forming cardboard boxes and predetermined fold lines with various different techniques. For example, cardboard can be crushed with a straight edge from a localized deformation of the corrugated inner layer of the cardboard, which thereby causes the cardboard to be preferentially folded along the fold line where the fold line acts more or less like a hinge. Depending on how the fold line is created, the material can still have a bias towards an unfolded state. Thus, in the orientations in
With reference to
This can provide an optional additional benefit. For example, as the retention member 310 is inserted into the container 350, the protruding portions 355, 359 can cause the panels 341, 345 to bend inwardly about the fold lines 321, 323, respectively. Then, as the retention member 310 is pushed further downwardly into the position illustrated in

The top panels 864, 866, 868, 870 can be considered as serving as major and minor flaps, as referred to commonly in the packaging industry. For example, where the top panels 864 and 868 are folded inwardly first in use, they would form a first inner layer within the container, and the remaining top panels 866, 870 can be folded on top of panels 864, 868, and thereby serve as “major” flaps.
Similarly, the bottom panels 872a, 872b, 872c, 872d can be paired into major and minor flaps. In the illustrated embodiment, the flaps 872b and 872d serve as the minor flaps and include additional features for forming the cushioning structures 851, 853, respectively (
For example, in some embodiments, minor flaps 872b and 872d can have an extended length compared to that of the major flaps 872a, 872c. Additionally, the minor flaps 872b, 872d can include additional fold lines to provide for convenient and preferential folding into a desired shape of the cushioning structures 851, 853. For example, in some embodiments, the minor flap 872b includes fold lines 872b1 and 872b2. Optionally, the minor flap 872b can include an additional fold line 872b3. In some embodiments, the minor panel 872b includes only a single additional fold line, for example, only one of fold lines 872b1 or 872b2 or other fold lines. Optionally, the minor flap 872d can also include optional combinations of additional fold lines 872d1, 872d2, and 872d3.
When assembled into the configuration illustrated in
The minor flap 872b can be folded along fold lines 872b1 and 872b2, so as to form a structure doubled back upon itself, thereby forming a first lower inner wall portion and a second upper inner wall portion spaced apart by the distance defined between the fold lines 872b1, 872b2. Further, optionally, the minor flap 872b can be folded along fold line 872b3, so as to form an additional surface that can be adhered to the inner sidewall 856 of the container 850, so as to secure the cushioning structure 851 in the desired configuration. The minor flap 872d can be folded in the same or a similar way to form the cushioning structure 853.
In the sectional view of
In the assembled configuration of
In these configurations, the cushioning structures 851, 853 can be conveniently formed by simply folding portions of a single continuous piece of corrugated cardboard to form an entire container having fully enclosed sides and bottoms as well as integrated cushioning structures. The position and shape of the cushioning structures 851, 853 can vary in accordance with desired performance characteristics.
The retention system 900 includes a container 950 having protruding portions 955, 959, such as those included in the retention system 300 (
For example, as shown in
Further, the lower flaps of the container 950 include major flaps 972a, 972c and minor flaps 972b, 972d. The minor flaps 972b can include any combination of optional fold lines 972b1, 972b2, 972b3.
