Suspension packaging system
A suspension packaging system can include a retention member having at least one pocket and a relatively more rigid member configured to be inserted into the pocket and folded into a state in which a tension in the retention member is increased. The more rigid member can be in the form of a tray and can include protrusions over which the pocket is placed. The protrusions can then be moved into engagement with apertures thereby engaging the resilient member between the protrusion and the aperture. Additionally, flaps of a box can be inserted into pockets of a resilient member and rotated so as to generate attention in the retention member so as to provide further cushioning of an article to be packaged therein.
1. Field of the Invention
The present inventions are directed to a packaging system. In particular, the present inventions are directed to a suspension packaging system that includes a retention member having at least one pocket.
2. Description of the Related Art
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 to the box that can occur during loading, transit and unloading.
In most cases, some additional structure is used to keep the article from moving uncontrollably in the box and thus incurring damage. 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 within the box so as to spaced from the walls defining 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. 6,675,973 discloses a number of inventions directed to suspension packaging assemblies which incorporate frame members and retention members. For example, many of the embodiments of the u.s. Pat. No. 6,675,973 patent include the use of a retention member formed of a resilient material. Additionally, some of the retention members include pockets at opposite ends.
In several of the embodiments disclosed in the U.S. Pat. No. 6,675,973 patent, free ends of the frame members are inserted into the pockets of the retention member. The free ends of the frame member are then bent of folded to tension the retention member. Because the retention member is made from a resilient material, the retention member can stretch and thus provide a mechanism for suspending an article to be packaged, for example, within a box.
SUMMARY OF THE INVENTIONOne aspect of the present invention includes the recognition that a retention sleeve having pockets can be used with frame members such that at least one of the pockets receives a protruding member of the frame member that is eventually interlocked with another portion of the frame member. As such, this type of retention member can be used in a variety of other types of devices thus improving the cushioning effect provided by these devices and/or providing additional devices.
For example, a retention sleeve having pockets formed therein at opposite ends thereof can be used in conjunction with a cardboard member folded to form a tray. This type of cardboard packaging member has been widely used in the packaging art. In this type of device, a relatively rigid material, such as, for example, but without limitation, corrugated cardboard, is cut into a generally rectangular shape and has foldable edges. Two or more of the edges can be shaped so as to have at least one protrusion at the distal edge thereof. When folded, the protrusion on the distal edge engages in an aperture formed at or near the proximal edge of the folding part. Thus, when folded, the protrusion locks into the aperture thereby forming a peripheral wall extending generally perpendicular to the central portion of the frame member.
With this type of device, the foldable portion can be inserted into a pocket of retention member having at least one pocket. The foldable portion can then be folded with the protruding part inserted into the aperture, thereby ensnaring the distal edge of the pocket between the protruding portion and the aperture. As such, the resilient nature of the retention member can be combined with the structural qualities of the frame member without the need for additional adhesives or connectors.
In accordance with another aspect of at least one of the inventions disclosed herein, a retention member having at least one pocket can be used in conjunction with flaps formed on a box. For example, when a box is assembled leaving one open end, usually there are four flaps remaining. Two of the flaps are folded first and then the remaining two flaps are folded over the first two flaps. The first two flaps to be folded closed can be inserted into pockets of a resilient retention member and thereby used to tension the retention member and provide additional suspension for the article package within the box.
In accordance with one embodiment, a packaging kit comprises at least one resilient retention member having a first end and a second end opposite the first end, and at least first and second pockets disposed at the first and second ends, respectively. At least one frame member includes a base portion and first and second foldable portions connected to and foldable relative to the base portion. The first foldable portion includes at least a first protrusion. The second foldable portion includes at least a second protrusion. The base portion includes at least first and second apertures configured to receive the first and second protrusions. The resilient retention member is sized such that the first foldable portion can be inserted into the first pocket and the second foldable portion can be inserted into the second pocket, and the first and second foldable portions can then be folded so as to engage the first and second protrusions with the first and second apertures, respectively, with the first and second pockets extending through the first and second apertures.
In accordance with another embodiment, a packaging kit comprises at least a first resilient retention member having at least a first pocket, and a base member having a base portion. A first aperture is disposed on the base portion. At least a first foldable portion is connected to and is rotatable relative to the base portion. The first foldable portion includes a protrusion sized to fit within the first aperture. The first foldable portion is sized to fit within the first pocket. The retention member is sized such that tension is generated in the retention member when the first foldable portion is inserted into the first pocket and the first protrusion is inserted into the first aperture.
In accordance with additional embodiment, a packaging kit comprises at least a first resilient retention member having at least a first pocket, and a base member having a base portion. A first aperture is disposed on the base portion. At least a first foldable portion is connected to and is rotatable relative to the base portion. The first foldable portion includes a protrusion sized to fit within the first aperture. Additionally, the kit includes means for ensnaring a portion of the first pocket between the aperture and the protrusion.
In accordance with another embodiment, a method is provided for packaging an article with a base member having a base portion and a foldable portion, the foldable portion having a protrusion configured to engage an aperture disposed on the base portion, and with a resilient retention member having at least one pocket. The method comprises inserting the foldable portion into the pocket, folding the foldable portion toward the base portion, engaging the protrusion with the aperture with a portion of the pocket being disposed between the protrusion and the pocket such that the portion of the pocket is pushed through the aperture by the protrusion, and supporting an article with the retention member.
For purposes of summarizing the inventions and the advantages achieved over the prior art, certain objects and advantages of the inventions have been described herein above. Of course, it is to be understood that not necessarily all such objects or advantages may be achieved in accordance with any particular embodiment of the inventions. Thus, for example, those skilled in the art will recognize that the inventions may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other objects or advantages as may be taught or suggested herein.
All of these embodiments are intended to be within the scope of the inventions herein disclosed. These and other embodiments of the present inventions will become readily apparent to those skilled in the art from the following detailed description of the preferred embodiments having reference to the attached figures, the inventions not being limited to any particular preferred embodiment(s) disclosed.
BRIEF DESCRIPTION OF THE DRAWINGSThese and other features of the inventions will now be described with reference to the drawings of several embodiments of the present packaging assembly and kit which are intended to illustrate, but not to limit the inventions. The drawings contain the following figures:
An improved packaging system is disclosed herein. The packaging system includes an improved structure which provides new alternatives to known suspension packaging devices.
In the following detailed description, terms of orientation such as “upper,”“lower,”“longitudinal,”“horizontal,”“vertical,”“lateral,”“midpoint,” and “end” are used here to simplify the description in the context of the illustrated embodiment. Because other orientations are possible, however, the present inventions should not be limited to the illustrated orientation. Those skilled in the art will appreciate that other orientations of the various components described above are possible.
In the illustrated embodiment, the pockets 14, 16 are formed of folds 18, 20 formed in the resilient body 12 which have been attached (e.g., heat sealed) along lateral opposite edges thereof. In this embodiment, the heat sealing process forms the heat sealing lines 22, 24, 26, 28. The heat sealing lines 22, 24, 26, 28 can be continuous or formed of a plurality of heat-sealed points. One of ordinary skill in the art will appreciate that there are numerous methods for forming pockets in a resilient sheet material such as the resilient body 12. However, it has been found that heat sealing is particularly advantageous as it does not require expensive adhesives and the time consuming steps required for using it adhesives.
The retention member 10 has a length L1 that is sized depending on the other devices with which the retention member 10 is to cooperate. Thus, the length L1 can be sized such that when the retention member is in its final state, e.g., engaged with folding members of another device, it generates the desired tension for the corresponding application. Thus, the length L1 will be smaller where a higher tension is desired and will be larger where a lower tension is desired. Additionally, the length L1 might be different for different sized articles that are to be packaged. One of ordinary skill in the art can determine the length L1 for the corresponding application.
The retention member 10 can be formed of any resilient material. In some embodiments, the retention member 10 can be made of applicable polyethylene film. However, virtually polymer, elastomer, or plastic film can be used to form the retention member 10. The density of the film can be varied to provide the desired retention characteristics such as overall strength, resiliency, and vibrational response. Preferably, the density of the retention member 10 is determined such that the retention member 10 is substantially resilient when used to package a particular article.
With reference to
The tray member 40 can be constructed from various materials, including but without limitation, paper, cardboard, corrugated cardboard, plastic, and/or other appropriate materials. The chosen material for constructing the tray member 40 can be any substantially rigid but foldable material. It will be appreciated that, although denominated as rigid, the chosen material would preferably have a certain amount of flexibility in the cases of extreme physical impact. In some embodiments, the material used to form the tray member 40 is a single wall corrugated C-flute cardboard.
Each of the foldable portions 44, 46, 48, 50 include a proximal portion 52 that is disposed proximal to the base portion 42 and a distal portion 54 that is disposed distally from the base portion 42. The proximal portions 52 generally define a connection between the foldable portions 44, 46, 48, 50 and the base portion 42.
Each of the proximal portions 52 include a fold line 56. The fold lines 56 can be formed as perforations in the tray member 40, i.e., broken cut lines passing partially or completely through the material forming the tray member 40. In the alternative, or in addition, the fold lines 56 can be crushed portions of the material forming the tray member 40. Of course, depending on the material used to construct the tray member 40, the fold lines 56 can be formed as mechanical hinges, thinned portions or any other appropriate mechanical connection which would allow various portions of the tray member 40 to be folded or rotated with respect to each other.
In the illustrated embodiment, the foldable portions 44, 46, 48, 50 also include medial fold lines 58. The medial fold lines 58 allow each of the foldable portions 44, 46, 48, 50 to be folded. As such, in this embodiment, each of the foldable portions 44, 46, 48, 50 can be folded in half to define a double-walled portion around a periphery of the base member 42.
The distal portions 54 also include at least one protrusion 60. In the illustrated embodiment, each of the distal portions 54 include two protrusions 60. However, the number of protrusions 60 on the distal portions 54 can be varied.
The protrusions 60 on the distal portions 54 are configured to engage with apertures 62 disposed in the vicinity of the proximal portions 52. Thus, when the foldable portions 44, 46, 48, 50 are folded about the medial fold lines 58, the protrusion 60 can be inserted into the apertures 62, thereby securing the foldable portions 44, 46, 48, 50 into place. This technique is well known in the art.
With continued reference to
In order to assemble the tray member 40 into a tray-shaped device, the corner members 64 can first be folded upwardly, as viewed in
Then the foldable portions 44, 48 can be folded about the medial fold lines 58 until the protrusions 60 engage with the apertures 62. The foldable portions 44, 48 can be sized such that as the foldable portions 44, 48 are folded about the medial fold line 58, the protrusions 60 snap into the apertures 62, thereby locking the foldable portions 44, 48 into that folded state.
With the corner member 64 aligned with the fold lines 56 of the foldable portions 46, 50, the foldable portions 46, 50 can be folded about their medial fold lines 58 in a similar manner. Thus, when the protrusions 60 of the foldable portions 46, 50 are engaged with the apertures 62, the corner members 64 are sandwiched within the respective foldable portions 46, 50, thereby locking the foldable portions 44, 46, 48, 50 together. This provides an enhanced structural rigidity of the tray member 40.
With reference to
In order to assemble the tray member 40, as noted above, the foldable portion 50 is folded about the fold line 56 and the fold line 58 until the protrusion 60 is engaged with the apertures 62. Additionally, the foldable portion 46 is also folded in a similar manner. When folded as such, the retention member 10 is stretched by the foldable portions 50, 46. The amount of tension generated by the folding of the foldable portions 46, 50 can be adjusted by adjusting the length L1 of the retention member 10 (

Additionally, in the illustrated embodiment, the cut lines 82 are generally arranged in the shape of a “I”. Additionally, the base member 42 includes a plurality of score lines 84. The score lines extend generally from the comers of the base member 42 toward the cut lines 82. The score lines 84 can be formed in the same manner as any of the above noted fold lines 52, 58, 66. Preferably, however, the score lines 84 include discontinuous cuts extending through the material forming the base member 42.

The tray member 100 includes foldable portions 46, 50 arranged opposite each other. Additionally, the tray member 100 includes foldable portions 102, 104 that are also disposed opposite each other. The foldable portions 102, 104 do not include the medial fold line 58 that are included with the foldable portions 46, 50. Rather, the foldable portions 102, 104 are configured to form only a single wall when in the assembled state. Thus, the distal portions 54 of the foldable portions 102, 104 do not include the protrusions 60. Additionally, the proximal portions 52 of the foldable portions 102, 104 do not include apertures 62.
The foldable portions 102, 104 can include corner members 64 attached to the foldable portions 102, 104 at fold lines 66. The foldable portions 102, 104 also include retaining grooves 106 configured to cooperate with an optional wall member 108.
The optional wall member 108 can be formed by providing one or a plurality of cut or score lines 110 in the base member 42. In the illustrated embodiment, the cut or score lines 110 extend around a periphery of the wall member 108.
The cut or score lines 110 can also define one or a plurality of anchor grooves 112. The anchor grooves 112 are sized to as to be alignable with the alignment grooves 106.
The cut or score lines 110 can also define a locking notch 114. The locking notch 114 can be used in conjunction with other devices or portions of the tray member 100, described in greater detail below.
In some embodiments, the tray member 100 can also include a lock panel 120. The lock panel 120 can be configured to lock the wall member 108 relative to the base portion 42. In the illustrated embodiment, the lock panel 120 is defined by cut or score lines 122. The cut or score lines 122 can be arranged to define a locking tab 124 configured to engage the notch 114. Additionally, the lock panel 120 can include a fold line 126 configured to allow the panel 120 to be rotated relative to the base member 42.

For example, with reference to
Returning to
As illustrated in
It is to be noted that with the wall member 108 removed from the base portion 42, the base portion 42 is provided with enhanced flexibility. Thus, when the tray member 100 is used to support an article, such as the article 70 illustrated in
The tray member 100′ can include a plurality of cut lines 140. Additionally, or in the alternative, the tray member 100′ can include a plurality of score or fold lines 142. The inclusion of cut lines 140 and/or score or cut lines 142 allows the tray member 100′ to behave in a manner described above with reference to the tray member 40″ and with reference to
Additionally, with reference to the tray members 100, 100′, the foldable portions 46, 50 can be inserted into the pockets of a resilient member, such as the resilient member 10 illustrated in
The container member 140 includes a plurality of bottom flaps 142, a plurality of wall panels 144, and a plurality of top flaps 146. Additionally, the container member 140 can include a wall connector member 147.
The wall panels 144 are identified as wall panel 144A, 144B, 144C, 144D. The wall panels 144A, 144B, 144C, 144D, can be connected along fold lines 148. The construction of the bottom flaps 142, wall panels 144, and connector 146 can be in accordance with the long and well known technique for forming a cardboard box out of a single piece of cardboard.
For example, the plurality of wall panels 144 can be folded along the fold lines 146 and the connector 147 can be attached to the wall panel 144A, so as to form a box. Additionally, the bottom flaps 142 can be folded and secured in a known manner to form a bottom of a box. Assembled as such, the container member 140 takes the shape illustrated in
With reference again to
By including at least one fold line in at least one of the plurality of top flaps 146, the container member 140 can be used in conjunction with a retainer member such as the retainer member 10 illustrated in
However, a further advantage can be achieved where one of the tray members 40, 40′, 40″, 100, 100′ and a retention member, such as the retention member 10 are used to support the article 70 in a position spaced from the bottom of the container member 140.
In this arrangement, the retention member 10 is engaged with the top flaps 146B, 146D and the top flaps 146B, 146D are folded inwardly so as to tighten the retention member 10 across the top of the article 70. Additionally, the corners of the top flaps 146B, 146D created by the folding of the top flaps about the fold lines 152, 156 can be tucked between the upper periphery of the tray member T and the wall panels 144B, 144D, respectively. As such, the top flaps 146B, 146D are held in place and thus, generate tension in the retention member 10.
Additionally, the remaining top flaps 146A, 146C can be folded over the top flaps 146B, 146D to thereby further retain the top flaps 146B, 146D in the position shown in
Of course, the foregoing description is that of certain features, aspects and advantages of the present invention to which various changes and modifications can be made without departing from the spirit and scope of the present invention. Moreover, the packaging system may not feature all objects and advantages discussed above to use certain features, aspects, and advantages of the present inventions.
