     FIELD 
     The described embodiments relate generally to packaging systems, and more particularly, to mechanisms and techniques for reliably securing packaging components to one another. 
     BACKGROUND 
     Corrugated packaging can be used to ship appliances of various sizes and purposes. In many traditional applications, flaps or panels of the packaging can be tape- or glue-closed. This can provide a difficult or messy consumer-opening experience that can require the use of tools, such as a sharp knives or box cutters, and generally complicate the un-boxing of the appliance. Many traditional packaging systems suffer from significant drawbacks that can contribute to wasted time and user frustration. As such, the need continues for systems and techniques that facilitate the un-boxing of an appliance. 
     SUMMARY 
     Embodiments of the present invention are directed to a packaging clip. The packaging clip can be a biased packaging clip, including a spring biased box clip that is used to releasably secure components of a packaging to one another. For example, a packaging can include an outer box and an inner box arranged substantially within the outer box, such as being positioned within a boundary or perimeter of the outer box. The inner and outer boxes can be formed from a corrugated material, and can be adapted for holding products, such as a beverage machine, and/or components or accessories thereof. The boxes can generally be used to provide a protective barrier around the inner box, such as that used for shipping and/or presentation to a consumer or a retailer. Additionally or alternatively, the packaging can include overlapping panels of the same box. 
     The packaging clip generally operates to releasably secure the inner and outer boxes to one another, or other substantially adjacent packaging components. In this regard, the packaging clip can be a multi-component assembly that is integrated with packaging panels, such as any sidewall or otherwise designated portions of the boxes. As an illustration, a first attachment mechanism of the clip can be integrated with a first panel or first box portion and a second attachment mechanism can be integrated with a second panel or second box portion. A locking mechanism of the clip is engageable with the first and second attachment mechanisms to arrange the first and second panels in a secured configuration. In the secured configuration, a biasing mechanism including a helical spring can be compressed. The locking structure can generally be turnable by a user, such as by a quarter, half, or other turn, in order to release the first and second panels from one another. Upon the release from the secured configuration the compressed biasing element can release stored energy, causing the locking structure to be biased outward, proud from the panels, helping indicate the released configuration, as described herein. 
     Several embodiments are contemplated and described herein. For example, in an embodiment, a packaging system is disclosed. The packaging systems can include an inner box and an outer box. The packaging system can further include a packaging clip integrated with each of the inner and outer boxes. The packaging clip can be configured to, in a first mode, secure the inner and outer boxes to one another in a closed configuration. The packaging clip can be further configured to, in a second mode, release the inner and outer boxes from the closed configuration using a biasing structure. 
     In another embodiment, the packaging clip can include a locking mechanism including the biasing structure. The locking mechanism can be manipulateable to transition the packaging clip from the first mode to the second mode. The locking mechanism can further include a turnable locking structure engaged with the biasing structure, the turnable locking structure being configured to rotate from a first position to a second position. In this regard, a rotation of the turnable locking structure to the second position transitions the packaging clip to the second mode. 
     In another embodiment, in the first mode, the turnable locking structure can generally be arranged at the first position and the biasing structure can be compressed, having potential energy. Further, in the second mode, the turnable locking structure can generally be arranged at the second position and the spring can be substantially uncompressed, the potential energy being released and the turnable locking structure arranged proud with respect to an exterior-facing surface of the outer box. This can provide a visual indication of release of the inner box from the outer box. In some examples, the second position of the turnable locking structure can be a rotational quarter turn from the first position. 
     In another embodiment, one or both of the inner or outer boxes can be formed from a corrugated material. The corrugated material can be configured to structurally support an appliance for shipment, the appliance including a beverage machine. In some examples, at least a portion of the packaging clip attached to the packaging is formed from a plastic material. 
     In another embodiment, a packaging clip is disclosed. The packaging clip includes a first panel attachment mechanism configured for attachment to a first packaging panel. The packaging clip further includes a second panel attachment mechanism configured for attachment to a second packaging panel. The packaging clip further includes a locking mechanism engaged with the first and second attachment mechanisms for releasable coupling of the first and second packaging panels. The locking mechanism includes a biasing structure configured to bias the locking mechanism proud from the first panel attachment mechanism, indicating release of the first and second packaging panels from a secured configuration. 
     In another embodiment, the first panel attachment mechanism can include a first panel fastener base and a first panel fastener top. The first panel fastener base and the first panel fastener top can be configured to attach to opposing sides of the first packaging panel. Further, each of the first panel fastener base and the first panel fastener top can define an opening configured to receive the locking mechanism therethough. The locking mechanism can include a rim configured to engage one or both of the first panel fastener base and the first panel fastener top at the opening. 
     In another embodiment, the biasing structure can include a spring arranged substantially between the first panel fastener base and the rim of the locking mechanism. The biasing mechanism can be configured to bias the rim of the locking mechanism toward the first panel fastener top. The second panel attachment mechanism can include a second panel fastener base and a second panel fastener top. The second panel fastener base and the second panel fastener top can be configured to attach to opposing sides of the second packaging panel. 
     In another embodiment, the locking mechanism can include a turnable locking structure having an engagement portion configured to be received by at least one of the second panel fastener base or the second panel fastener top. In this regard, the turnable locking structure can be turnable relative to the second panel attachment mechanism in order to restrain movement of the locking mechanism away from the second panel attachment mechanism. 
     In another embodiment, the turnable locking structure can further be turnable relative to the second panel attachment mechanism in order to allow movement of the locking mechanism away from the second panel attachment mechanism. The biasing structure can include a spring engaged with the turnable locking structure to bias the turnable locking structure to a proud position relative to an exterior of the first and second packaging panels. Further, the second panel fastener top can define an elongated through portion. The engagement portion of the turnable locking structure can include a radial tongue arranged substantially perpendicular to an axis of rotation of the turnable locking structure and configured to extend fully through the elongated through portion when aligned with the elongated through portion. In this regard, when the radial tongue is position fully through the elongated through portion, and when the turnable locking structure is rotated to misalign the radial tongue with the elongated through portion, movement of the turnable locking structure away from the second panel fastener top can be restricted. 
     In another embodiment, the first packaging panel can be a panel of an outer box. And the second packaging panel can be a panel of an inner box, with the inner box being arranged substantially within the outer box. In some examples, one or both of the first packaging panel or the second packaging panel can be formed from a corrugated material. 
     In another embodiment, a method for releasably securing a product packaging using a packaging clip is disclosed. The method includes attaching a first panel attachment structure to a first packaging panel. The method further includes attaching a second panel attachment structure to a second packaging panel, the second packaging panel arranged substantially adjacent the first packaging panel. The method further includes securing the first and second packaging panels to one another using a locking mechanism including a biasing structure configured to bias the locking mechanism proud from the first panel attachment mechanism for indication of a release of the first and second packaging panels from a secured configuration. 
     In another embodiment, the operation of securing further includes inserting a radial tongue of an engagement portion of the locking mechanism at least partially into the second panel attachment structure and compressing the biasing structure. In some examples, the operation of securing further includes inserting the radial tongue into an elongated opening of the second panel attachment structure, and misaligning the radial tongue with respect to the elongated opening when the radial tongue is inserted through the elongated opening. 
     The method can further include rotating the locking mechanism a quarter turn, thereby aligning the radial tongue for the release the first and second packaging panels from the secured configuration. The operation of rotation further includes generating a tactile output in response to a release of the first and second packaging panels. 
     In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the drawings and by study of the following description.

     DETAILED DESCRIPTION 
     The description that follows includes sample systems, methods, and apparatuses that embody various elements of the present disclosure. However, it should be understood that the described disclosure may be practiced in a variety of forms in addition to those described herein. 
     The following disclosure describes systems, devices, and techniques related to securely and reliable releasably securing packaging components. Packaging components can include corrugated materials that are used to box a product for presentation and delivery to a consumer or retailer. The product can be an appliance, such as a beverage machine, or another appliance engaged in the production of beverages. The packaging can include a first box for enclosing the appliance (or components thereof), and a second box, which can form a base supporting the appliance in the packaging. The first and second boxes can be arranged relative to one another in order to fully enclose the appliance within the boxes for shipping, retail presentation, or the like. In some examples, the first box can be an upper box that is nested inside of the second box, and which defines a lower box or base of the packaging. In other cases, the second box can be nested within the first box. For example, the second box can define the lower box or base of the packaging, and the first box can be an upper box fitted around the lower box. 
     Packaging can also include overlapping panels of a single box, an interface between multiple packaging elements, including multiple protective packaging elements, and so on. Glues, tapes, twine, and other techniques for restraining movement of the boxes or other corrugated panels, relative to one another can detract from a user “un-boxing” experience, due to at least mess, time, and possible need for unavailable tools. Such adhesive-based techniques also fail to provide a satisfactory indication to the user that the boxes are released, or pending release, from one another and thus are not necessarily communicative of the configuration of the boxes or likelihood of ready separation. 
     The packaging system of the present disclosure can mitigate such hindrances, thereby allowing for releasably coupling packaging components, such as an inner and an outer box, without the need for specialized tools or sharp instruments. Adhesives and glues can also be reduced or eliminated. In one example, the packaging system includes a packaging clip having a biasing mechanism. The packaging clip is generally used to releasably secure at least a first panel (e.g., of an outer box) and second panel (e.g., of an inner box) of the packaging system to one another, in a first mode. In a second mode, the packaging clip can be manipulated to release the panels from one another facilitated by the biasing structure. 
     In the transition to the second mode, the packaging clip can produce an audible, tactile, and/or visual indication of the released configuration of the panels. For example, the biasing structure can move a portion of the locking mechanism to a proud position relative to the outermost surface of the packing, thereby indicating a released configuration. The multi-component assembly of the packaging clip being connected in various manners to the respective panels of the packaging, the clip can remain with the product packaging in the released configuration, allowing for easy disposal. 
     To facilitate the foregoing, the packaging clip can generally include at least a first panel attachment mechanism and a second panel attachment mechanism. The first panel attachment mechanism and the second panel attachment mechanism can each attach to respective panels or portions of the packaging. The packing clip can further include a locking mechanism for engagement with each of the first and second attachment mechanisms. The packaging clip can be at least partially be inserted into or through the first and second attachment mechanisms and substantially prevent movement of each attachment mechanism relative to one another. 
     While many constructions are contemplated herein, the locking mechanism can generally include a turnable locking structure and the biasing structure. The turnable locking structure can include an engagement portion that is configured to extend at least partially into the second panel attachment mechanism for retaining the locking mechanism relative to the second panel attachment mechanism. For example, the second panel attachment mechanism can include an elongated through portion and the engagement portion can define a radial tongue that is receivable by the elongated through portion when aligned. When the radial tongue is received through the elongated through portion and the radial tongue is misaligned with the elongated through portion, the radial tongue is prevented from exit, thereby preventing movement of the locking mechanism away from the second packaging panel. The locking mechanism can also be engaged with the first panel attachment mechanism. For example, the turnable locking structure can define a rim that is engageable with an opening defined by the first panel attachment mechanism, thereby constraining movement relative to the first packaging panel. 
     The biasing structure can generally be arranged to bias the locking structure toward an outermost exterior of the product packaging. For example, the biasing structure can be a helical spring that is seated about the engagement portion of the turnable locking structure. When the turnable locking structure is engaged with the second panel attachment mechanism, as described herein, the biasing structure can be substantially compressed. For example, the radial tongue of the engagement portion being fully received through the elongated opening and misaligned therewith can substantially prevent the turnable locking structure from moving substantially away from the second panel attachment mechanism, notwithstanding the compressed spring. 
     The turnable locking structure also can define a user interface surface that is manipulateable in order to release the engagement portion from the second panel attachment mechanism. For example, the user interface surface can have a grooved handle that can be engaged by a user and turned. In some examples, a quarter turn can cause the radial tongue and the elongated through portion to substantially align. Once substantially aligned, the stored energy of the compressed biasing structure is released, thereby causing the radial tongue to exit the second panel attachment mechanism. With this release, the locking mechanism can then be biased out from an outermost surface of the product packaging, indicating the product packaging being in a released configuration and the panels therefore being separable by a user in order to remove an appliance. 
     Reference will now be made to the accompanying drawings, which assist in illustrating various features of the present disclosure. The following description is presented for purposes of illustration and description. Furthermore, the description is not intended to limit the inventive aspects to the forms disclosed herein. Consequently, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the present inventive aspects. 
     With reference to  FIGS. 1A-1H , an embodiment of a sample packaging system is shown using a packaging clip, such as the packaging clips discussed above and described in greater detail below. In particular, a packaging system  100  is shown in which a first box  104   a  and an second box  104   b  are releasably secured to one another using a packaging clip  120 . The packaging clip  120  can connect overlapping portions or panels of the first box  104   a  and the second box  104   b , allowing the boxes to remain securely fastened to one another, for example, during transport or retail presentation. The packaging clip  120  can be a spring-biased clip, accordingly to the embodiment described herein. Thus, the packaging clip  120  can receive a user input, such as a twist, and cause release of the second box  104   b  relative to the outer box  104 . In the example of  FIG. 1A , the second box  104   b  is shown nested at least partially within the first box  104   a  and the packaging clip  120  is manipulateable relative to the first box  104   a . In other examples, as shown in  FIG. 1F  below, the first box  104   a  is arranged substantially within the second box  104   b.    
     The first box  104   a  and the second box  104   b  can cooperate to conceal a beverage machine or other appliance or consumer good. Thus, the release of the first and second boxes  104   b ,  104   a  relative to one another can permit the unboxing of the beverage machine without the accompanying mess of glues, tapes, adhesive and/or the use of auxiliary tools. One or both of the first box  104   a  or the second box  104   b  (or portions thereof) can be formed from a corrugated material and be of sufficient strength and character to structurally support an appliance, such as supporting an appliance for shipment and delivery to a consumer or retailer. Sample appliances include beverage machines, such as those used to produce single-serve beverages, including single-serve alcoholic beverages; however, it will be appreciated that the first box  104   a  and the second box  104   b  are merely illustrative and that other packages are contemplated herein for use with the packaging clip  120 , such as that shown with respect to  FIGS. 2A-3B . 
     By way of particular example,  FIG. 1A  shows the first box  104   a  forming a base or a bottommost portion of the packaging system  100 . The first box  104   a  can generally, and as described herein, support the beverage machine or appliance within the packaging system  100 , and thus can include or be associated with certain internal packaging components, such as internal corrugated materials, shelves, structures, and so on to support and optionally protect contents within the system from damage. The first box  104   a  can thus provide or define, along associated components, a structural base for the respective appliance within the system  100 . 
     The second box  104   b  shown in  FIG. 1A  can fit within a perimeter of the outer box  104   b . The second box  104   b  can thus be interior to the first box  104   a , while a portion of the second box  104   b  can define an external surface of the packaging system  100 . The second box  104   b  can define a volume configured to enclose the appliance within the packaging system  100 . In some examples, the second box  104   b  can have or be associated with internal corrugated materials or other features to protect the contents of the packaging; however, this is not required. 
     The first and second boxes  104   a ,  104   b  can generally be constructed of panels  106 . As shown in the example of  FIG. 1A , the panels  106  of the first and second boxes  104   a ,  104   b  can having an overlapping portion  107 . At the overlapping portion  107 , the panels  106  of each box can be position substantially adjacent one another, allowing for attachment and securing by the packaging clip  120 . In particular, the overlapping portion  107  can having a width or other dimension that is sufficient to accommodate the packaging clip  120 , such that the packaging clip  120  is encompassed within the overlapping portion  107 . 
     In this regard, as shown in  FIG. 1A , the packaging clip  120  is arranged connected to each of the first box  104   a  and the second box  104   b  at the overlapping portion  107  of the panels  106 . In the sample of  FIG. 1 , the packaging clip  120  is shown in a configuration in which the packaging clip  120  operates to restrain movement of the outer and inner boxes  104   a ,  104   b  relative to one another. As explained herein, the packaging clip  120  can in turn be manipulated, allowing for release and relative movement of the outer and inner boxes  104   a ,  104   b , revealing the beverage machine or other contents held therein. 
     While the overlapping portion  107  can generally be arranged at any appropriate location within the packaging system  100 , in the sample of  FIG. 1A , it is shown along a bottommost region.  FIG. 1A  shows the packaging clip  120  installed at the overlap portion  107  on a first side. It will be appreciated that multiple packaging clips, such as the packaging clip  120 , can be used to releasably secure the first and second boxes  104   a ,  104   b . In this regard,  FIG. 1B  shows another side of the packaging system  100  having the packaging clip  120  integrated therewith. As such, the packaging system  100  is shown having two of the packaging clips  120  at the overlapping portion  107 , one on either side. It will be appreciated that in other embodiments a single packaging clip can be used to releasably secure the first and second boxes  104   a ,  104   b , while in other examples, three, four, or more packaging clips can be used. 
     Turning to  FIG. 1C , a detail view of the packaging clip  120  is shown. The packaging clip  120  is shown in the configuration of  FIG. 1A , in which the packaging clip  120  operates to releasably secure the first and second boxes  104   a ,  104   b  to one another. In this configuration, the packaging clip  120  can be substantially flush or flat relative to a surface of the panels  106 . This can provide a visual indication of the boxes be secured. For example, the surface of the panels  106  shown in  FIG. 1C  can be a surface of the first box  104   a , such as may be case in an embodiment in which the second box  104   b  is nested within the first box  104   a . Alternatively, the surface of the panels  106  shown in  FIG. 1C  can be a surface of the second box  104   b , such as may be the case in an embodiment in which the first box  104   a  is arranged substantially within the second box  104   b.    
     As shown in  FIG. 1C , the packaging clip  120  includes a locking mechanism  130 . The locking mechanism  130 , as explained in greater detail below, includes one or more components that cooperate to attach the first and second boxes  104   a ,  104   b  to one another. For example, the locking mechanism  130  can include a substantially rigid members that operates to secure the first and second boxes  104   a ,  104   b  in a first configuration. The rigid member or other component of the locking mechanism  130  can be manipulated for release of the boxes, facilitated by the action of an internal spring or other biasing mechanism, which pushes the rigid member out for detaching of the boxes and establishing a visual indication of the release. For example, the locking mechanism  130  can be turnable, such as a quarter or other turn, causing such release. 
       FIG. 1D  shows the packaging clip  120  in a second configuration in which packaging clip  120  is configured to release the first and second boxes  104   a ,  104   b , permitting relative movement thereto. The locking mechanism  130  is shown in  FIG. 1D  as being manipulated by a quarter turn and biased outward from the first box  104   a , indicating such release. And with reference to the detail view of  FIG. 1E , the locking mechanism  130  is generally rotatable along direction R 1  which can be the quarter turn. Upon rotation of the locking mechanism  130 , as described herein, one or more biasing structures of the locking mechanism  130  can cause a portion of the locking mechanism  130  to protrude out from the outermost surface of the panels  106 , such as along a direction D 1  shown in  FIG. 1E . 
     Upon release, the first and second boxes  104   a ,  104   b  can be separated from one another to reveal a beverage machine  101  or other appliance of contents, as shown in  FIG. 1F , within an interior volume  109  of the packaging system  100 . As also shown in  FIG. 1F , the packaging clip  120  can generally include a first panel attachment mechanism  150  and a second panel attachment mechanism  170 . As described in greater detail below, the first and second panel attachment mechanism  150 ,  170  can each attach to panels  106  of respective ones of the first and second boxes  104   a ,  104   b . The locking mechanism  130  generally engages both the first and second panel attachment mechanism  150 ,  170  when overlapped, thus retraining relative movement of the first and second boxes  104   a ,  104   b . Upon manipulation of the locking mechanism  130 , the locking mechanism  130  can disengage from, for example, the second panel attachment mechanism  170 . The second box  104   b  being unrestrained by the locking mechanism  130 , a user can thus lift the second box  104   b  along a direction L 1  for unboxing of the beverage machine  101  without tools. This not only facilitates ease of unboxing, it also helps protect the beverage machine  101  from possible damage, such as that which could be caused by a sharp instrument opening a glue- or tape-closed packaging. 
     For purposes of illustration, the packaging system  100  is shown in  FIGS. 1A-1F  above in a configuration in which the second box  104   b  is nested within the first box  104   a . In this regard, the first panel attachment mechanism  150  including the locking mechanism  130  is shown arranged on the first box  104   a , and the second panel attachment mechanism  170  is shown arranged on the second box  104   b.    
     In other examples, the packing system  100  can be arranged so that the first box  104   a  is arranged substantially within the second box  104   b , as illustrated in  FIG. 1G . Accordingly, the first panel attachment mechanism  150  including the locking mechanism  130  can be arranged on the second box  104   b . Further, the second panel attachment mechanism  170  can be arranged on the first box  104   a . In this regard, and as shown in  FIG. 1H , the locking mechanism  130  can be manipulate from the second box  104   b  and cause a release of the first box  104   a , thereby permitting relative movement of the first and second boxes  104   a ,  104   b  to reveal the beverage machine  101  contained therein. 
     As described herein, the packaging clip  120  can be used in a variety of systems, helping releasably secure two overlapping or partially overlapping portions of material. In this regard,  FIGS. 2A-3B  illustrate further implementations of the packaging clip  120 , including using the clip to secure two nested boxes ( FIGS. 2A-2B ), as well as securing overlapping panels of a single box ( FIGS. 3A-3B ). It will be appreciated, however, that these examples are presented as illustrations and are not intended as limiting. In other examples, the packaging clip  120  can be used to secure other aspects of other packaging system, including packaging systems having different shapes, sizes, contours, materials, and so on. 
     With reference to  FIGS. 2A and 2B , a sample packaging system  100 ′ is shown with the packaging clip  120 . In the embodiment of  FIGS. 2A and 2B , the first box  104   a  and the second box  104   b  can serve a variety of purposes. As an illustration, it can be desirable to have a multi-box system in order to package or box certain product components separately, such as packaging separate components of an appliance in separate inner boxes, separately packaging consumables, and so on. Such boxes can also be specifically tailored to the requirements of the product or consumable, including considerations for fragile components. In this regard, in the example of  FIG. 2A , the second box  104   b  can generally be used to hold one or more of such product components. Additionally or alternatively, the second box  104   b  can hold an entire appliance, and be labeled with consumer-facing materials. 
     The second box  104   b  (or multiple inner boxes) can be inserted into the first box  104   a , which too can serve multiple functions, illustrated herein. For example, the first box  104   a  can be a box that is used for shipping or warehousing and thus has can have different structural characteristic from that of the second box  104   b . Additionally or alternatively, the first box  104   a  can be configured to hold an entire appliance and the second box  104   b  (or multiple inner boxes) can be individual components of the appliance system (e.g., a beverage machine, beverage pods, accessories, and so on). In this regard, it will be appreciated that the packaging system  100 ′ is presented for purposes of illustration and that the packaging clip  120  can be used to releasably secure a variety of packaging components, such as those illustrated herein. In other examples, the first and second boxes  104   a ,  104   b  can serve a variety of other purposes. 
     In the example of  FIG. 2A , one or both of the first and second boxes  104   a ,  104   b  can generally have a shaped defined the group of panels  106 . The panels  106  can be generally arranged to form a box or parallelepiped shape, and with reference to  FIG. 2B , having an opening  108  and an interior volume  109 . The packing clip  120  can be installed and integrated with the first box  104   a  and the second box  104   b  in order to define a closed or secure configuration shown in  FIG. 2A . In the secure configuration, movement of the second box  104   b  relative to the first box  104   a  is general restricted. With reference to  FIG. 2B , the packaging clip  120  can generally be turnable, such as a quarter turn, in order to release the packaging components from one another. 
     With reference to  FIG. 3A , a packaging system  100 ″ is shown. In the embodiment of  FIG. 3A , the packaging system  100 ″ includes a packaging  104 . The packaging  104  can be a single box or other packaging item that is used to house a beverage appliance, other boxes, and so on. The packaging  104  can be formed from corrugated panels that generally define an enclosed structure having the opening  108  that extends into the interior volume  109 . The packaging  104  can also have overlapping panels  106   a ,  106   b  at the opening  108 . The overlapping panels  106   a ,  106   b  can be articulated over the opening  108  to close the packaging  104 . 
     The packaging clip  120  can generally be used to releasably secure the overlapping panels  106   a ,  106   b  to one another. For example, the first panel attachment mechanism  150  can be attached to the panel  106   a  and the second panel attachment mechanism  170  can be attached to the panel  106   b . As described above, the locking mechanism  130  can be rotated in order to release the panels from a secure configuration. With reference to  FIG. 3B , the locking mechanism  130  is shown turned, indicating the panels  106   a ,  106   b  being released for movement relative to one another. 
       FIG. 4A  depicts a cross-sectional view of the sample packaging system of  FIG. 1A , taken along line  4 A- 4 A of  FIG. 1A .  FIG. 4A  shows the first panel attachment structure  150  including a first panel fastener top  152  and a first panel fastener base  158 , each engaged with a first packaging panel  106   a .  FIG. 4A  further shows the second panel attachment structure  170  including a second panel fastener top  172  and a second panel fastener base  170 , each engaged with a second packaging panel  106   b . One or more of the first panel attachment structure  150 , the second panel attachment structure  170 , or the locking mechanism  130  can be formed from a plastic material 
     In the closed or secure configuration shown in  FIG. 4A , the locking mechanism  130  is used to secure the first and second panels  106   a ,  106   b  to one another. For example, the locking mechanism  130  can include a turnable locking structure  132  that can be engaged with each of the first and second attachment mechanisms  150 ,  170 . The turnable locking structure  132  can include an engagement portion  134  with a radial tongue  135  that is received at least partially within the second panel attachment mechanism  170 , such as being received through an elongated opening  174 . The radial tongue  135  is shown in  FIG. 4A  misaligned with the elongated opening  174 , thereby substantially preventing exit of the engagement portion  134  from the second attachment mechanism  170 . 
       FIG. 4A  further shows a biasing element  162 . The biasing element  162  can be seated substantially about the engagement portion  134  and used to bias the turnable locking structure  132  away from the first panel attachment mechanism  150 . For example, the biasing element  162  can be positioned substantially between an annular rim of the turnable locking structure  132  and the first panel fastener base  158 . 
     With reference to  FIG. 4B , a cross-sectional view of the sample packaging system of  FIG. 1B  is shown, taken along line  4 B- 4 B of  FIG. 1E . In this configuration, the turnable locking structure  132  is shown rotated, such as rotated a quarter turn. With the rotation of the turnable locking structure  132 , the radial tongue  135  is aligned with the elongated opening  174  and the thus the operation of the biasing element  162  acts to move the locking mechanism  130  away from (and out of) the second panel attachment mechanism  170 . The biasing structure further causes the turnable locking structure  132  to rise from an outer most surface of the first panel  106   a  to a protruding position indicative of the release of the panels. In some examples, this can further product an audible or tactile sensation. 
       FIG. 5A  depicts a top view of a first panel fastener base  158 .  FIG. 5B  depicts a cross-sectional view of the first panel fastener base  158 , taken along line  5 B- 5 B of  FIG. 5A . As described herein, the first panel fastener base  158  can generally be used to secure the first panel attachment mechanism  150  to a panel of a packaging system. In this regard, the first panel fastener base  158  can be a generally planar or disc-like structure, such as that shown in  FIGS. 5A and 5B . 
     The first panel fastener base  158  can include an opening  504 . The opening  504  can have a width or other dimension for receiving some or all of the locking structure  130  and allowing the locking structure  130  to rotate therein. The opening  504  is generally alignable with an opening in a respective panel of a packaging system and with an opening or other features of a corresponding attachment mechanism for another panel. 
     The first panel attachment base  158  can implement a variety of structures to facilitate attachment to a panel. In the embodiment of  FIGS. 5A and 5B , the first panel fastener base  158  is shown having a panel mating surface  508  and tabs  510 . The panel mating surface  508  can generally be a substantially planar feature configured for contacting a surface of a panel. The tabs  510 , such as the four tabs shown in  FIG. 5A , can extend generally away from the panel mating surface  508  for optional engagement with a panel. For example, in some embodiments, the tabs  510  can extend into or partially into a thickness of a panel. This can help fix the first panel fastener base  158  relative to the panel. 
     The first panel fastener base  158  can also include a fastener engagement feature  512 . The fastener engagement feature  512  can be a lip or other feature that is configured to contact and engage first panel fastener top  152 . As such, the first panel fastener base  158  and the first panel fastener top  152  can be fixed relative to one another. The first panel fastener base  158  can also include a shelf  516 . The shelf  516  can be defined by an annular portion substantially surrounding the opening  504 . The shelf  516  is configured to receive a portion of the biasing element  162 , proving a landing or seat for the biasing element within the first panel attachment mechanism  150 . 
       FIG. 6A  depicts a top view of a first panel fastener top  152 .  FIG. 6B  depicts a cross-sectional view of the first panel fastener top  152 , taken along line  6 B- 6 B of  FIG. 6A . As described herein, the first panel fastener top  152  can generally be used to secure the first panel attachment mechanism  150  to a panel of a packaging system. In this regard, the first panel fastener top  152  can be a generally planar or disc-like structure, such as that shown in  FIGS. 6A and 6B . 
     The first panel fastener top  152  can include an opening  604 . The opening  604  can have a width or other dimension for receiving some or all of the locking structure  130  and allowing the locking structure  130  to rotate therein. The opening  604  is generally alignable with an opening in a respective panel of a packaging system and with an opening or other features of a corresponding attachment mechanism for another panel. 
     The first panel attachment top  152  can implement a variety of structures to facilitate attachment to a panel. In the embodiment of  FIGS. 6A and 6B , the first panel fastener top  152  is shown having a panel mating surface  608 . The panel mating surface  608  can generally be a substantially planar feature configured for contacting a surface of a panel. In some examples, tabs or other features can extend from the panel mating surface  608  for engagement with a panel, such as extending into or partially into a thickness of a panel to retrain movement therewith. This can help fix the first panel fastener base  158  relative to the panel. 
     The first panel fastener top  152  can also include a fastener engagement feature  612 . The fastener engagement feature  612  can be a lip or other feature that is configured to contact and engagement first panel fastener base  158 . As such, the first panel fastener top  152  and the first panel fastener base  158  can be fixed relative to one another. 
       FIG. 7A  depicts a top view of a second panel fastener base  178 .  FIG. 7B  depicts a cross-sectional view of the second panel fastener base  178 , taken along line  7 B- 7 B of  FIG. 7A . As described herein, the second panel fastener base  178  can generally be used to secure the second panel attachment mechanism  170  to a panel of a packaging system. In this regard, the second panel fastener base  178  can be a generally planar or disc-like structure, such as that shown in  FIGS. 7A and 7B . 
     The second panel fastener base  178  also provide a structural backstop for the locking mechanism  130 . For example,  FIG. 7A  shows the second panel fastener base  178  having a backstop  704 . The backstop  704  can limit movement of the locking mechanism  130  into the product packaging. This can help align the locking mechanism  130  with the second panel attachment mechanism  170 . For example, upon insertion of the locking mechanism  130  into the second panel attachment structure  170 , the backstop  704  can tactilely indicate to a user that the locking mechanism is fully inserted, prompting a user to rotate the locking mechanism for securing the respective panels. 
     The second panel attachment base  178  can implement a variety of structures to facilitate attachment to a panel. In the embodiment of  FIGS. 7A and 7B , the second panel fastener base  178  is shown having a panel mating surface  708 . The panel mating surface  708  can generally be a substantially planar feature configured for contacting a surface of a panel. In some examples, tabs or other features can extend from the panel mating surface  708  for engagement with a panel, such as extending into or partially into a thickness of a panel to retrain movement therewith. This can help fix the second panel fastener base  178  relative to the panel. 
     The second panel fastener base  178  can also include a fastener engagement feature  712 . The fastener engagement feature  712  can be a lip or other feature that is configured to contact and engage the second panel fastener top  172 . As such, the second panel fastener base  178  and the second panel fastener top  172  can be fixed relative to one another. 
       FIG. 8A  depicts a top view of a second panel fastener top  172 .  FIG. 8B  depicts a cross-sectional view of the second panel fastener top  172 , taken along line  8 B- 8 B of  FIG. 8A . As described herein, the second panel fastener top  172  can generally be used to secure the second panel attachment mechanism  170  to a panel of a packaging system. In this regard, the second panel fastener top  172  can be a generally planar or disc-like structure, such as that shown in  FIGS. 8A and 8B . 
     The second panel fastener top  172  also provides a structure for receiving and retaining the locking mechanism  130  in a secured configuration. For example,  FIGS. 8A and 8B  show the second panel fastener top  172  including an elongated opening  174 . The elongated opening  174  can define an entrance for receiving the radial tongue or other feature of the locking structure. In this regard,  FIG. 8A  shows the elongated opening  174  as including a main portion  808  and a wing  812 . The wings  812  can be configured to receive a radial tongue of the locking mechanism  130 . The radial tongue can therefore be aligned with the wings  812  in order to advance the locking mechanism  130  further into the second panel attachment mechanism  170 . Once the radial tongue passes into the second panel attachment mechanism and fully through the wings  812 , the locking mechanism  130  can be rotatable, misaligning the radial tongue within the second panel attachment mechanism relative to the wings  812 . 
     The second panel attachment top  172  can implement a variety of structures to facilitate attachment to a panel. In the embodiment of  FIGS. 8A and 8B , the second panel fastener top  172  is shown having a panel mating surface  816 . The panel mating surface  816  can generally be a substantially planar feature configured for contacting a surface of a panel. In some examples, tabs or other features can extend from the panel mating surface  816  for engagement with a panel, such as extending into or partially into a thickness of a panel to retrain movement therewith. This can help fix the second panel fastener top  172  relative to the panel. 
     The second panel fastener top  172  can also include a fastener engagement feature  812 . The fastener engagement feature  820  can be a lip or other feature that is configured to contact and engage the second panel fastener base  178 . As such, the second panel fastener base  178  and the second panel fastener top  172  can be fixed relative to one another. 
       FIG. 9  depicts an exploded view of the locking mechanism  130 . The locking mechanism  130  can include the turnable locking structure  132  and the biasing element  162 . As described herein, the biasing element  162  is configured to exert a biasing force on the turnable locking structure. As such, when the turnable locking structure  132  is engaged in a configuration for securing the panels to one another, the biasing element  162  helps retaining the turnable locking structure in a position pressed partially against one or both panels or associated attachment mechanisms. The turnable locking structure  132  is rotatable for release of the panels for movement relative to one another. In this release configuration, the biasing element  162  moves the turnable locking structure  132  away from the panels to a proud position indicating the released configuration. 
     To facilitate the foregoing, the turnable locking structure  132  is shown having the engagement portion  134  and the radial tongue, described above with respect to  FIGS. 4A and 4B . The turnable locking structure  132  can also have a handle portion  904 . The handle portion  904  can be a pocket, indent, groove, nub, or other appropriate feature that allows a user to manipulate the turnable locking structure  132 . 
     The turnable locking structure  132  can also include a rim  908 . The rim  908  can define an engagement surface for the biasing element  162 . In this regard, and with return reference to  FIGS. 4A and 5B , the biasing element  162  can be axially constrained by the rim  808  of the turnable locking structure  132  and the shelf  516  of the first panel fastener base  158 . In other embodiments, other components of the first or second panel attachment mechanisms  150 ,  170  can operate to axially constrain the biasing element  162  along with the features of the turnable locking structure  132 , such as the rim  908 . 
     The first panel attachment mechanism  150  and the second panel attachment mechanism  170  are described above as sample attachment structures for the packaging clip  120 . The attachment mechanisms broadly are used to establish a fixed structural connection to a respective one of the packaging panels. In other embodiments, other attachment mechanisms can be used. 
     In this regard,  FIGS. 10A-12B  present another embodiment of an attachment mechanism, a packaging mechanism  1050 . The packaging mechanism  1050  can be a component of any of the packaging clips described herein, such as the packaging clip  120 . For example, the packaging mechanism  120  of  FIGS. 4A and 4B  can include the packaging mechanism  1050  in lieu of the first panel attachment mechanism  150 . In other embodiments, the packaging mechanism  1050  can be used with other constructions of the packaging clip  120 , as contemplated herein. 
     The attachment mechanism  1050  allows for attachment to a packaging system from a single side of a panel. This can simplify installation of the attachment mechanism  1050 , and packaging clip  120  more broadly, by integrating the attachment mechanism  1050  with an exterior of a fully assembled and packaged product. That is, the outermost box or panel of the packaging system need only have an opening or hole for insertion of the attachment mechanism, expanding the variety of panels and boxes that can be used for secure attachment to an inner panel enclosing the packaging contents. 
     In the illustration of  FIG. 10A , the attachment mechanism  1050  is shown having a fastener top  1020  and a fastener bottom  1040 . The fastener top  1040  and the fastener bottom  1040  can be connected to one another and separated from a product packaging in a preinstalled stated. For example,  FIG. 10A  shows the fastener top  1020  and the fastener bottom  1040  connected to one another and separated from a panel  1004 . The panel  1004  can be an outermost panel of a packaging system. 
     The locking mechanism  1050  can be associated with a locking mechanism  1060 . The locking mechanism  1060  can be substantially analogous to the locking structure  130  described above in relation to  FIGS. 1A-9 ; redundant explanation which is omitted here for clarity. For example, the locking mechanism  1060  can include a radial tongue  1064  and can be engaged with the attachment mechanism  1050  at least partially between the fastener top  1020  and the fastener bottom  1040 . A biasing element (not shown in  FIG. 10A ), such as a spring, can be positioned between the fastener top  1020  and the fastener bottom  1040 , allowing the locking mechanism  1060  to be biased outward, proud from the fastener top  1020  when the locking mechanism  1060  is in a disengaged configuration. 
     In the pre-installed state of  FIG. 10A , the attachment mechanism  1050  and associated locking mechanism  1060  are shown separated from the panel  1004 . The panel  1004  can define a panel opening  1008  for receiving the attachment mechanism  1050 . For example, the panel opening  1008  can generally have a shape for receiving the fastener bottom  1040 . Once received by the panel opening  1008 , the fastener bottom  1040  can rotated axially, misaligning elements of the fastener bottom  1040  for securing the attachment mechanism  1050  to the panel  1004 . This configuration can allow for installation of the attachment mechanism  1050  from a single side of the panel  1004 . A packaging system can therefore optionally exclude other structures, components, adhesives, and the like arranged on the opposing side of the panel  1004 , simplifying manufacturing and installation. 
     In the embodiment of  FIG. 10 , the fastener bottom  1040  includes wings  1044 . The wings  1044  extend radially from a perimeter of the fastener bottom  1040  and along a substantially common direction. The panel opening  1008  thus can define the main portion  1010  and a grooved section  1012 . The wings  1044  are alignable with the grooved section  1012  of the panel opening  1008 , permitting the fastener bottom  1040  to move therethough. The wings  1044  can subsequently be encouraged to move through the panel opening  1008  and beyond the panel  1004 , and the fastener bottom  1040  can rotate therein, misaligning the wings  1044  with the grooved section. 
     In this regard,  FIG. 10B  shows the fastener bottom  1040  extending through the panel opening  1008  and having the wings  1044  misaligned with the grooved section  1012 . In this installed configuration shown in  FIG. 10B , the attachment mechanism  1050  is fixed relative to the panel  1004 . The attachment mechanism  1050  can also include other features to facilitate attachment to the panel  1004 . For example,  FIGS. 10A and 10B  show the fastener top  1020  having tabs  1024 . The tabs  1024  are shown as protruding from an underside of the fastener top  1020 . As the attachment mechanism  1050  is installed within the opening, the tabs  1020  can contact the exterior surface of the panel  1004 . Upon receipt of the attachment mechanism  1050  and fastener bottom  1040  within the panel opening, the attachment mechanism  1050  is turned, such as a quarter turn, and the tabs  1024  can engage with respective ends of the grooved section  1012  of the panel opening  1008 , as shown in  FIG. 10B . Once received within the respective ends of the grooved section  1012 , the wings  1044  can help prevent the attachment mechanism  1050  from rotating or otherwise disengaging from the panel  1004  and panel opening  1008 . 
       FIG. 11A  depicts a top view of a panel fastener top of the panel attachment mechanism of  FIG. 10A .  FIG. 11B  depicts a cross-sectional view of the panel fastener top of  FIG. 11A , taken along line  11 B- 11 B of  FIG. 11A . As described herein, the faster top  1020  can generally be used to secure the attachment mechanism  1050  to a panel of a packaging system. In this regard, the fastener top  1020  can be a generally planar or disc-like structure, such as that shown in  FIGS. 11A and 11B  and includes the tabs  1024  described herein. 
     The fastener top  1020  can include an opening  1022 . The opening  1022  can have a width or other dimension for receiving some or all of the locking structure  130  and allowing the locking structure to rotate therein. The opening  1022  is generally alignable with an opening in a respective panel of a packaging system and with an opening or other features of a corresponding attachment mechanism for another panel, such as the panel opening  1008  of  FIGS. 10A and 10B . 
     In addition to the tabs  1024 , the fastener top  1020  can implement other structures to facilitate attachment to a panel of a packaging system. In the embodiment of  FIGS. 11A and 11B , the panel fastener top  1020  is shown as having a panel mating surface  1028 . The panel mating surface  1028  can generally be a substantially planar feature configured for contacting a surface of a panel, facilitating engagement therewith. 
     The panel fastener top  1020  can also include a fastener engagement feature  1032 . The fastener engagement feature  1032  can be a lip or other feature that is configured to contact and engage panel fastener base  1040 . As such, the panel fastener top  1020  and the panel fastener base  1040  can be fixed relative to one another. 
       FIG. 12A  depicts a bottom view of a panel fastener bottom of the panel attachment mechanism of  FIG. 10A .  FIG. 12B  depicts a cross-sectional view of the panel fastener bottom of  FIG. 12A , taken along line  12 B- 12 B of  FIG. 12A . As described herein, the fastener bottom  1040  can generally be used to secure the attachment mechanism  1050  to a panel of a packaging system. In this regard, the fastener bottom  1040  can be a generally planar or disc-like structure, such as that shown in  FIGS. 12A and 12B  and include the wings  1044  described herein. In the embodiment of  FIGS. 12A and 12B , the wings  1044  are shown having ribs  1045 . The ribs  1045  can help provide rigidity and strength to the fastener bottom  1040 . 
     The fastener bottom  1040  can include an opening  1042 . The opening  1042  can have a width or other dimension for receiving some or all of the locking structure  130  and allowing the locking structure to rotate therein. The opening  1042  is generally alignable with an opening in a respective panel of a packaging system and with an opening or other features of a corresponding attachment mechanism for another panel, such as the panel opening  1008  of  FIGS. 10A and 10B . 
     In addition to the wings  1044 , the fastener bottom  1040  can implement other structures to facilitate attachment to a panel of a packaging system. In the embodiment of  FIGS. 12A and 12B , the panel fastener bottom  1040  is shown as having a panel mating surface  1052 . The panel mating surface  1052  can generally be a substantially planar feature configured for contacting a surface of a panel, facilitating engagement therewith. 
     The panel fastener top  1020  can also include a fastener engagement feature  1046 . The fastener engagement feature  1046  can be a tab or other feature that is configured to contact and engage panel fastener top  1020 . As such, the panel fastener top  1020  and the panel fastener base  1040  can be fixed relative to one another. 
     To facilitate the reader&#39;s understanding of the various functionalities of the embodiments discussed herein, reference is now made to the flow diagram in  FIG. 13 , which illustrates process  1300 . While specific steps (and orders of steps) of the methods presented herein have been illustrated and will be discussed, other methods (including more, fewer, or different steps than those illustrated) consistent with the teachings presented herein are also envisioned and encompassed with the present disclosure. 
     In this regard, with reference to  FIG. 13 , process  1300  relates generally to a method for releasably securing a product packaging. The process  1300  can be used with any of the packaging clips and spring biased packaging clips described herein, for example, such as the packaging clip  120  of  FIG. 1A , and variations and combinations thereof. 
     At operation  1304 , a first panel attachment structure can be attached to a first packaging panel. For example and with reference to  FIG. 4A , the first panel attachment structure  150  can be attached to the first packaging panel  106   a . The first panel attachment structure  150  can include the first panel fastener top  152  and the first panel fastener base  158 . The first panel fastener top  152  can be positioned along a first side of the first packaging panel  106   a  and the first panel fastener base  152  can be positioned along a second side of the first packaging panel  106   a , opposite the second side. The first packaging panel  106   a  can include a hole, aperture, or other feature for receiving the first panel attachment mechanism  150 . In this regard, a portion of the first panel fastener top  152  and the first panel fastener base  158  can be arranged within the hole. This can help secure the first panel fastener top  152  and the first panel fastener base  158  to one another, such as by allowing each component to contact or otherwise engage one another therein. For example, one or both of the first panel fastener top  152  and the first panel fastener base  158  can include one or more engagement features that connect to one another within an aperture of the first packaging panel  106   a . In other examples, other structures can be used, establishing the first panel attachment structure  150  as being substantially fixed relative to the first packaging panel  106   a.    
     At operation  1308 , a second panel attachment structure can be attached to a second packaging panel. For example, with reference to  FIG. 4A , the second panel attachment structure  170  can be attached to the second packaging panel  106   b . The second panel attachment structure  170  can include the second panel fastener top  172  and the second panel fastener base  178 . The second panel fastener top  172  can be positioned along a first side of the first packaging panel  106   b  and the second panel fastener base  172  can be positioned along a second side of the second packaging panel  106   b , opposite the second side. The second packaging panel  106   b  can include a hole, aperture, or other feature for receiving the second panel attachment mechanism  170 . In this regard, a portion of the second panel fastener top  172  and the second panel fastener base  178  can be arranged within the hole. This can help secure the second panel fastener top  172  and the second panel fastener base  178  to one another, such as by allowing each component to contact or otherwise engage one another therein. For example, one or both of the second panel fastener top  172  and the second panel fastener base  178  can include one or more engagement features that connect to one another within an aperture of the second packaging panel  106   b . In other examples, other structures can be used, establishing the second panel attachment structure  150  as being substantially fixed relative to the second packaging panel  106   b.    
     At operation  1312 , the first and second packaging panels can be secured to one another using a locking mechanism. The locking mechanism can include a biasing structure that is configured to bias the locking mechanism proud from the first panel attachment mechanism. For example and reference to  FIGS. 4A and 4B , the locking mechanism  130  can include the turnable locking structure  132  having a radial tongue  135 . To secure the panels to one another, the radial tongue can be inserted through or partially through the first and second attachment structures  150 ,  170 . Once inserted, the radial tongue  135  can be misaligned, preventing release of the panels. The biasing element  162  helps secure the panels to one another in this configuration, helping prevent the radial tongue from exiting the attachment structures, until the locking mechanism  130  is manipulated by a user. Upon such manipulation, as described herein, the biasing element  162  can bias the locking mechanism  130  to a position proud from the first panel attachment mechanism  150 . This in turn releases the panels for relative movement and indicates to a user for configuration. 
     Other examples and implementations are within the scope and spirit of the disclosure and appended claims. For example, features implementing functions can also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations. Also, as used herein, including in the claims, “or” as used in a list of items prefaced by “at least one of” indicates a disjunctive list such that, for example, a list of “at least one of A, B, or C” means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Further, the term “exemplary” does not mean that the described example is preferred or better than other examples.
