1. Technical Field
This invention generally relates to containers and, more particularly, to merchandise storage containers that are used to deliver the merchandise to the customers. The exemplary configurations of the invention are described with respect to the field of media disc storage containers. Specifically, the present disclosure relates to a tray for holding a media disc and, more particularly, to a tray for holding a media disc that includes both biodegradable and recyclable materials.
2. Background Information
Various merchandise storage containers are known in the art. Some of the most common storage containers for recorded media discs are injection molded, plastic book-like containers having a lid connected to a base with a pair of living hinges. These containers typically allow a printed promotional slip sheet to be carried between the lid/hinge/base and a transparent cover that defines a pocket. This arrangement allows the molded container to be used for a different media discs by adding printed material specific to the media disc to the container. The most popular types of these containers include some form of a media disc hub that engages the central opening of the media disc to secure the disc within the container. A wide variety of these hubs exist including passive and active pluck-off hubs and push button hubs. A variety of security locks are provided for these containers.
A drawback with these molded containers is the overall weight and the volume of plastic used in the container. As the industry moves towards more recyclable containers and containers that use fewer materials and energy during their manufacture, container consumers wish to reduce the amount of plastic in their containers as well as making the containers more recyclable. Ecologically sustainable products and manufacturing methods have become increasingly popular in today's marketplace. Not only are such products popular with consumers, but recent improvements in materials allow manufacturers to be environmentally friendly while still providing durable and reliable products. One problem with forming containers out of recycled material is that the holding features for the merchandise must be robust or the merchandise will release from the holder increasing the chance that the merchandise will break. In the field of media disc packaging, disc hubs manufactured from recycled materials have experienced a higher failure rate than traditional hubs made from virgin materials.
One example of such a sustainable product is a media tray that can be used to store and transport data media, such as optical discs. The product is made of an organic starch based material in place of the traditional petroleum based plastic commonly used in such trays. One problem with such trays has been providing a durable and flexible hub suitable for reliably retaining the optical discs in place in the tray. While biodegradable starch resins are available and have been used to make such flexible hubs, these hubs have generally provided poor results, especially during shipping. That is, the hubs fail and allow the media to shift and move in the trays during shipping, which often results in damage.
Accordingly, it would be beneficial to provide a sustainable tray for storing and transporting data media that avoids the problems described above.
The invention provides a container wherein the features of the container that hold and protect the merchandise are fabricated from one material that is generally robust while the remaining portions of the container are fabricated from a material that is weaker and may be a recycled material.
One configuration of the invention provides a merchandise storage container that combines a minimal recyclable plastic storage holder with recyclable-paper-based container body. In one configuration, the majority of the minimal holder is disposed under a portion of the paper-based body out of the sight of the user. The feature or features that hold the merchandise protrude up through the portion of the paper-based body that covers most of the minimal holder.
Another configuration of the invention provides a merchandise storage container that combines a minimal recyclable plastic storage holder combined with a recyclable container body. The holder and container are made from different materials suitable for their purposes. The holder uses a material having properties desirable for holding the merchandise. The container uses a material that is generally less expensive than the material of the holder and may be a recycled material.
One configuration of the invention provides a sustainable tray for storing data media that is made of a biodegradable material and includes a durable and flexible hub portion such as one made of plastic for retaining the data media.
In one configuration, the two elements are joined together during the molding of one of the elements. The invention also provides a method for making the container wherein the holder is molded directly to the container body.
Another aspect of the invention is the structure and arrangement of the holder and the manner in which it cooperates with the body of the container.
Another aspect of the invention is the manner in which the holder is secured to the body of the container.
Another aspect of the invention is the structure of a disc hub that is used to hold a media disc in the container.
Another aspect of the invention is the combination and arrangement of the disc hub with a push tab that engages the outer edge of the disc.
The different aspects of the invention may be used individually or in combination.
Similar numbers refer to similar parts throughout the specification.
A first configuration of the container is indicated generally by the numeral 2 in the accompany drawings. Container 2 generally includes a container body 4 that is defined by a base panel 10, a lid panel 12, and an inner panel 14. When container 2 is closed as shown in
Holder 30 may be fabricated from plastic and may be injection molded. Holder 30 has a base wall 50 that defines a plurality of openings 52 that reduce the amount of plastic needed to form holder 30. Openings 52 are arranged to have no sharp corners and to define no straight arms that run entirely across base wall 50. Openings 52 alternate about hub 40 from large to medium. A medium opening 52 is removed to define a solid platform 54 disposed intermediate hub 40 and push tab 44. Base wall 50 defines a pair of notches 56 on either side of push tab 44 that allows push tab 44 to resiliently pivot down with respect to base wall 50. Notches 56 extend radially inwardly past outer nest wall 42.
Portions of base wall 50 are used to secure holder 30 to body 4. In the exemplary configuration, holder 30 defines four tabs 60 that are adhesively connected to the inner surface of base panel 10 and may optionally be adhesively connected to the inner surface of inner panel 14 when inner panel 14 is closed on holder 30 to trap holder 30 in place. Tabs 60 may be disposed in the same place as existing prior art adhesive connection points used with existing automated packaging equipment so that container 2 may be run through the existing automated packaging equipment. The adhesive allows holder 30 to be removed from body 4 to allow the individual portions of container 2 to be individually recycled after container 2 has been used. In another configuration, holder 30 may be configured with portions that snap over the outer surface of inner panel 14 to define a snap fit between holder 30 and inner panel 14 so that holder 30 may be connected without adhesive.
Push tab 44 has at least one locking finger 70 that is disposed over the top edge of a media disc when the disc is held on hub 40. Pushing down on tab 44 pivots finger 70 upwardly and away from the disc edge to allow the disc to be lifted away from container 2. The space below locking finger 70 is configured to receive a portion of inner panel 14 and the thickness of the media disc held by holder 30.
Outer nest wall 42 has a ledge 72 that has an inner wall that abuts inner panel 14. The outer edge of the disc may rest on the upper surface of ledge 72. Outer nest wall 42 further has an outer blocking wall 74 that prevents the user from accessing the outer edge of the media disc. This configuration ensures that the user may only access the media disc from a single location in container 2 at the location of push tab 44 which must be depressed in order to remove the media disc from container 2.
Hub 40 includes a plurality of projections 80 that are disposed over the inner edge of the media disc when the media disc is held on hub 40. No single projection 80 is purposely aligned with push tab 44 so that the inner surface of the media disc may slide along the sidewall 82 of hub 40 when the media disc is being removed from container 2. In the exemplary configuration of hub 40, four projections 80 are disposed at 90 degree angles about hub 40. Projections 80 are disposed 45 degrees to the location of push tab 44.
Hub 40 generally includes five hub portions that define the upper wall 84 and the sidewall 82 of hub 40. The five hub portions provide flexibility to hub 40 while prevent unintentional release of the media disc. Hub 40 includes a plurality of feet 86 disposed between sidewall 82 and base wall 50 of holder 30. Feet 86 support the lower surface of the media disc and help locate hub 40 within opening 20.
Two projections 80 are disposed on independent hub portions (the first and fifth hub portions that are disposed on opposite sides of the hub). The projections are relatively flexible because of the configuration of the first and fifth hub portions. The remaining two projections 80 are disposed on a common hub portion (the central third portion) and are thus relatively stiff. This combination of the flexible projections 80 and the stiff projections 80 cooperate to retain the media disc in a relatively secure manner. The hub is not a push button-type hub such that pressing one's thumb on the top of hub 40 does not automatically release the disc or significantly move projections 80. The sidewall portion 82 of the second or fourth hub portion (that faces push tab 44) provides the smooth surface for the inner surface of the media disc to ride up as it is being removed from hub 40.
A second configuration of the container is indicated generally by the numeral 102 if
Container body 104 may be provided in a variety of shapes and sizes depending on the nature of the merchandise to be carried by container body 104. In the exemplary configuration, container body 104 is rectangular in shape and has a pair of side walls, a top wall, and a bottom wall that define an outer rim about the perimeter of body 104. Body 104 may be provided in the same length and width as a standard DVD container which is 135 mm×190 mm. The front surface of body 104 may be flat and continuous except where indented to define a nest 120 sized to receive a media disc such as a CD or DVD (nest diameter is greater than 120 mm), or other sized-media disc. The rear surface of body 104 may be indented to complement the front surface in order to reduce the amount of material that is used to form body 104. In other configurations, body 104 may be solid with areas removed for nest 120 and holder 106.
Nest 120 is defined by at its outer periphery by a nest sidewall 122 and at its lower extents by a nest bottom wall 124. Nest wall 122 may be continuous about the entire perimeter of nest 120 or may define one or more openings 126 to provide spaces for portions of holder 106 to protrude through body 104. Similarly, nest bottom wall 124 may be continuous or may define one or more openings 126 that provide spaces for portions of holder 106 to protrude through body 104. Openings 126 are shown in
Holder 106 is configured to securely retain the item of merchandise for which container 102 is to be used. In this example, holder 106 is configured to retain a media disc and thus includes at least a disc retaining hub 40 configured to be disposed through the central opening of a media disc to securely retain the disc. Hub 40 may have the structure described above or another structure suitable for holding a media disc. Holder 106 also may include a push tab 44 disposed in opening 126 at sidewall 122. Push tab 44 may have the structure described above or an alternative structure suitable for helping to secure the disc. In another configuration, container 102 may use hub 40 without push tab 44. In such a configuration, nest sidewall 122 may define a finger access opening or finger access indentation that allows the user to access the outer edge of the media disc when the disc is being removed from the container. In another configuration, container 102 may use a plurality of push tabs 44 or a single push tab 44 combined with another feature for securing the media disc at the outer perimeter of the disc. Such a configuration may not use central hub 40.
Container body 104 is fabricated separate from holder 106. Container body 104 may be made from a relatively inexpensive recycled product that does not have to be as robust as the material used to form holder 106 because container body 104 is not primarily responsible for retaining the item of merchandise with container 102. Container body 102 may be made from virgin plastics and/or recycled plastics such as polyethylenes (PE, PET, PETE, HDPE), polypropylene, polystyrene, other recycled plastics, or paper-based, starch-based, or fiber-based moldable materials such as those sold under the registered trademark PAPERFOAM®.
Holder 106 may be fabricated from a material that is desirable for disc hubs 40 and push tabs 44. Such materials include polypropylene, styrene, ABS, and other materials that are known to be used for disc hubs that are subjected to repeated bending forces. Hubs 40 are typically injection molded. Container 102 may be manufactured by molding holder 106 directly to container body 104 such that an adhesive or separate mechanical connectors are not need to form the secure connection between holder 106 and body 104. In this process, body 104 is placed in the mold for holder 106 and holder 106 is molded onto, through, or around body 104. In order to provide a secure connection between holder 106 and container body 104, body 104 may include one or more pedestals 130 that define overhangs around which a portion or portions of holder 106 are molded such that a portion of the material that forms holder 106 is disposed under the overhang. When holder 106 cools, a secure mechanical interlock is formed between the two elements to secure holder 106 to body 104. Molding holder 106 in this manner eliminates the need to manually connect the two elements after both are formed.
In the exemplary configuration, pedestal 130 is rectangular and provides four overhanging edges to receive the material that forms holder 106. Pedestal may be located intermediate hub 44 and push tab 44. In some combinations of materials, the material of holder 106 may bond directly to the material of container along the underside of body 104 to form another connection between holder 106 and body 104.
In another configuration of container 2, holder 106 is formed separately from container body 104 and then connected to container body 104 with an adhesive or with mechanical connectors.
A third configuration of the container is indicated generally by the numeral 202 in
As illustrated, outer push tab 214a is preferably connected to the central hub portion 214b via a plurality of spaced connecting elements 214d rather than as a larger single piece. The entire width of holder 214 is no greater than the width of outer push tab 214a. This configuration minimizes plastic use. When holder 214 is attached to tray 212, connecting elements 214d may be either embedded in the tray body 212 or embedded in a cardboard sleeve on which tray 212 is mounted. Alternatively, connecting elements 214d may be embedded both in tray 212 and on the cardboard sleeve. In the configuration depicted in
The central hub portion 214b preferably includes one or more projections 80 extending out over the inner edge of the center opening in the media 216 as described above. The primary force used to hold the media in place is applied at the periphery of the media at the release portion 214a, in contrast to most conventional trays. Since the hub structure 214 is preferably made of plastic, it is durable and flexible to reliably hold the media 216 in place.
Thus, container 202 of the present application includes both biodegradable material and some plastic material for those elements that require durability and resilience. Specifically, the hub structure 214 is made of plastic such that it provides a durable and reliable means for holding the media in place even during shipping. However, since the amount of plastic that is used in minimized and the plastic itself may be biodegradable, the overall negative affect of the tray 10 on the environment is minimized.
