1. Field of the Invention
The present invention relates to box constructions. More particularly, the invention pertains to box constructions suitable for high volume cost efficient packaging and order fulfillment for objects of variable size such as books, CD's, DVD's, and other objects that fall within that general size range.
2. Description of the Related Art
It is well known in the art to produce shipping and storage boxes in a wide variety of sizes and shapes. One of the most common is a hollow, six-sided cubic or three dimensional rectangular structure having corrugated cardboard side walls as well as top and bottom closures. It is also well known in the art to provide storage and shipping boxes for printed materials and other media such as books, CD's, DVD's and other objects that fit within the same volumetric dimensions. Such objects might include a wide variety of consumer retail and industrial products. It has been a disadvantage in the packaging and fulfillment industry to provide cost effective means for wrapping objects of varying sizes. Typically, an individual box size is needed for the dimensions of a given object size. Clearly, an object which is too large for its packaging either will not fit or will deform the box. Objects which are smaller than the box dimensions can be accommodated by either using padding or other dunnage or else they will be loose within the box during shipping and hence subject to damage. These constraints require that the fulfillment or packaging company keep a large inventory of different box sizes for shipping objects of varying sizes. With the advent of more on-line direct-to-consumer retail selling, the packaging and fulfillment of such on-line direct-to-consumer orders requires a more efficient process. The present invention provides a two-piece carton which can effectively serve a large range of randomly sized objects. The invention provides a carton for packaging objects which allows for variations in the size of the packaged product and yet provides a controlled retention of the product without changing the carton size, to minimize the chance for damage. Furthermore, the invention provides a design that can readily be automated for high volume lower unit cost fulfillment operations.
Most typical method of packaging and fulfillment utilize what is known in the industry as a knock down regular slotted case, or RSC, which requires the RSC to be erected into its shape, bottom sealed or taped, loaded with the objects, the dunnage must be added, and then the top must be closed and sealed. This method requires a great deal of labor and the packaging material costs can be relatively high. Another typical method is to use a die cut carton blank of a T-shaped design sized to fit the objects. These carton blanks, regardless of their many design variations, require special cutting dies for their manufacture. This is a considerable cost factor, especially when short production runs of varying carton sizes are required. This results in a need for a multitude of dies and substantial inventories of different carton sizes. Furthermore, many of the existing package designs do not lend themselves to high speed machine automation.
U.S. Pat. No. 4,322,028 shows a knock-down type mailing parcel case which comprises a rectangular cardboard main body having the opposite inwardly folded side edges and a pair of rectangular cardboard flaps extending perpendicular to the longitudinal axis of the main body and secured at one end to the folded side edges. U.S. Pat. No. 3,666,166 shows a wrapping set for packaging books or the like, comprising inner and outer panels, each panel being provided with inner and outer scored lines defining central, side and flap portions when said panels are folded at the lines. The inner panel is folded about the package contents, and the outer panel is then folded about the inner panel in a direction transverse to the following direction of the inner panel, and is adhered to the inner panel. U.S. Pat. No. 3,952,672 shows a pallet including an outer structure folded about an inner structure. U.S. Pat. No. 5,833,131 shows corrugated box constructions suitable for packaging, storing and transporting flat rectangular objects such as books. The box has an upper member and a lower member, each with a generally rectangular central panel, a pair of side panels, one of which is hingedly joined to each of the opposite ends of the central panel. Attached to each side panel of the upper member is an underlying panel and attached each side panel of the lower member is an overhanging panel. The side panels of the lower member fold upward, then the overhanging panel folds parallel to the central panel. The side panels of the upper member fold perpendicularly downward, then underlying panel folds under the central panel of the lower member. The upper member is attached to the lower member with an optional adhesive or strap. The construction allows for packaging products of various sizes.
It has been found that the two-piece carton design of this invention reduces the need for a large carton blank inventory since it allows for the use of one set of blanks for cartoning a multitude of product sizes, provides secure packaging for shipment without product damage and without the need for extra protective dunnage and lends itself to high speed automation for the increased volumes that today's direct-to-consumer fulfillment industry requires.
The invention provides a box construction comprising an outer member which comprises:
The invention also provides a method for enclosing an object which comprises the steps of:
In one embodiment the steps are conducted in the order I, and then II, and then III, and then IV, and then V.
Referring to
Outer member 2 has an intermediate side panel 22 having a length and a width defining two oppositely positioned longitudinal ends 24 and two oppositely positioned transverse ends 26 positioned perpendicular to the longitudinal ends 24. The intermediate side panel 22 is hingedly joined to an opposite transverse end 8 of the rectangular base panel 4 at an intermediate side panel fold line 28. The intermediate side panel fold line 28 extends between the intermediate side panel 22 and the rectangular base panel 4. The intermediate side panel 22 has a pair of dust panels 30. One dust panel is attached at each of the oppositely positioned transverse ends 24 of the intermediate side panel 22 at a dust panel fold line 32.
Outer member 2 has a rectangular top panel 34 having a length and a width defining two oppositely positioned longitudinal ends 36 and two oppositely positioned transverse ends 38 positioned perpendicular to the longitudinal ends 36. The rectangular top panel 34 is hingedly joined along one transverse end 38 of the rectangular top panel 34 to the intermediate side panel 22 at a second intermediate side panel fold line 40 opposite to the intermediate side panel fold line 28. Rectangular top panel 34 has a pair of outer end panels 42. One of the outer end panels 42 is hingedly joined to each of the longitudinal ends 36 of the rectangular top panel 34 at an outer end panel fold line 44 which extends a distance between said rectangular top panel 34 and its respective outer end panel 42. Outer member 2 further has an outer side panel 46, which is hingedly joined to the opposite transverse end 38 of the rectangular top panel 34 at an outer side panel fold line 48. The outer side panel fold line 48 extends a distance between said outer side panel 46 and the rectangular top panel 34.
Outer member 2 has a plurality of cavities 50. At least one cavity 50 is positioned through the inner side panel 10 at a position adjacent to the inner side panel fold line 12, and another cavity 50 being positioned through the intermediate side panel 22 at a position adjacent to the intermediate side panel fold line 52. Alternatively, at least one cavity 50 is positioned through each of the inner end panels 14 at a position adjacent to its respective inner end panel fold line 16 between the top panel 4 and the a respective first end panel 14. In one embodiment, the plurality of cavities 50 comprises a pair of cavities 50 which are positioned through the inner side panel 10 at a postion adjacent to the side panel fold line 12 and a pair of cavities 50 are positioned through the intermediate side panel 22 at a position adjacent to the intermediate side panel fold line 52.
In one embodiment of the invention, the inner side panel 10 comprises a plurality of minor panels 54 wherein the minor panels 54 are separated from one another by a notch 56. In another embodiment, box construction further comprises at least one viewing slot 58 through the rectangular base panel 4. This allows viewing product information or scanning of bar codes. In another embodiment base panel 4 further comprises an opening panel 60 which may be in the form of a series of perforations 62 optionally terminating at a finger hole 64.
In use, the invention providers a method for enclosing any object that fits within the interior of the formed outer box construction, including objects such as one or more books, or recording media such as CD-ROMS, CD, or DVDs. A box construction is formed by providing an outer member 2 and an inner member 66 as described above.
An object is then affixed onto a surface of the inner member 66. As seen in
One then folds the inner side panel 10, the inner end panels 14, the corner panels 18, the intermediate side panel 22, the dust panels 30, the rectangular top panel 34, the outer end panels 42, and outer side panel 46 on their respective fold lines in order to surround the object 74 on the inner member 66. One then attaches at least some of the inner side panel 10, the inner end panels 14; the dust panels 30, the outer end panels 42, and outer side panel 46 to its respective adjacent panel thus enclosing the object 74 within the box construction. Attaching may be via any known means such as via an adhesive, wrapping, taping, and the like. It is not necessary that each of the panels be attached to its adjacent panel. For example, corner panels 18 may be held in position by pressure from an inner side panel 10 and outer side panel 46 after the folding and attaching steps IV and V.
One method of opening the box construction in order to remove the objects 74 would be to tear open panel 60 by inserting a finger into finger hole 64, and then tearing the outer member along series of perforations 62, and then manually removing objects 74.
