The present invention relates generally to packing, storing, stacking, displaying, handling and shipping a dense, free-flowing material, for example, granular clay. In particular, the present invention relates to an improved integrated handle and a pour spout for a regular slotted carton.
Generally, the equipment required to erect, fill, and seal spill-proof boxes (SPB) is expensive and complicated. A provider of SPBs generally will not provide other packing formats for free-flowing material. In general, SPBs are created using a full overlap (FOL) design and have become increasingly popular as a consumer package format for pet absorbents such as cat litter. Regular slotted cartons (RSC) require less expensive equipment to erect but require two hands to hold, lift and pour as the RSCs do not include a single integrated handle. Presently, SPBs require two hands to hold, lift and pour. An alternative to both glued FOL SPBs and taped RSC with side handles is needed.
In one embodiment, this invention provides a cost-effective method of packing, storing, stacking, displaying, handling and shipping a dense, free-flowing material (granular clay). “Sift-Proof” Boxes (SPB) are created using a Full Overlap (FOL) design and have become increasingly popular as a consumer package format for pet absorbents (cat litter). In one embodiment, the invention provides an improved alternative to both glued FOL SPBs and taped Regular Slotted Cartons (RSC) with side handles.
No Special Equipment Needed:
The equipment needed to erect, fill, and seal SPBs is extremely expensive and complicated. Most companies that provide SPBs (for example Church & Dwight and Clorox Co.) will not provide other package formats (high density polyethylene (HDPE) jugs or pails). Once the incredible expense of purchasing, installing and operating the SPB line has been undertaken, the owner of the facility has few options other than to run SPBs, often exclusively. RSC boxes require less expensive equipment to erect, fill and seal, but RSC boxes do not offer a single integrated handle and require two hands to hold, lift, and pour. RSC boxes are generally referred to as “Bag-in-Box” systems in that they require a poly liner or bag to be placed into the box prior to filling. It is this poly liner that makes an RSC box leak proof. Companies that focus on private label packaging, like Bentonite Performance Mineral's Consumer Products Group (BPM CPG), have been asked by customers to provide a “box” that offers all of the attributes of the SPBs, but this needs to be done using BPM's existing manufacturing equipment. In one embodiment, the invention eliminates the need for specialized SPB erection and sealing equipment and allows BPM to use RSC box or even poly bag filling equipment.
Integrated Handle, Pour Spout:
The attributes most associated with SPBs include an integrated handle and a pour spout. In one embodiment, this invention offers an alternative design that has an improved integrated handle and a pour spout.
Improving Handle Integrity:
The SPB handles often tear or fail under load, especially in the larger sizes from 25-50 lbs. In one embodiment, this invention aims to improve the integrity of the handle while under load.
Handle Ergonomics:
SPBs use a poly or reinforced fiber (Tyvek) style handle between 1-2 centimeters (cm) in width. This places incredible stress on the hand and fingers while carrying and pouring. In one embodiment, the invention creates a far more comfortable handle that places the load over the full width of the hand and fingers.
Handle Placement:
SPBs have the handle at the top of the box. This leads to a generally awkward position when using the handle to pour material out as two hands must be used to pour the material out. In one embodiment, the invention allows for a more balanced position of the box while pouring and for pouring using a single hand/arm. The consumer for cat litter is often middle-aged to older women and a well-placed, comfortable handle that does not require bending over is extremely important and necessary to this demographic.
Handle Cavity:
In one embodiment, this invention integrates a design feature that creates a cavity allowing for the user's hand or fingers to be easily placed into the die-cut handle and prohibits the poly liner from interfering with placement of the hand.
Leakage:
SPBs aim to be leak-proof, but with the heavy bulk densities of cat litter, they often rack when being picked up by the handle. It is common for the small granules to leak out the sides and out the top and bottom glued flaps. This results in a mess for the retailer and the consumer. In one embodiment, this invention uses a poly liner to guard against leakage. In one embodiment, this invention also ensures all granules can easily be evacuated from the box by removing the liner.
In one embodiment, the invention is an RSC constructed box that integrates a pour spout, integrated handle, and internal liner. The resulting product has the increased attributes of a FOL SPB but does not need to be erected, filled and sealed using a SPB manufacturing line. SPBs are viewed as a “premium” consumer package format because of the increased functionality of the handle and pour spout. RSC boxes require less complex packaging lines and can be erected by hand or with limited packaging equipment. In one embodiment, the invention has the attributes of a sift-proof box and the simplicity in manufacturing of a RSC box.
Erecting & Sealing Capital and Equipment Required:
SPBs require an elaborate and expensive, automated packaging system. These are expensive, temperamental, and can only be used to make SPBs. These lines require an automated box erector, then the bottom must be glued, the box filled with product, and then the top glued and placed in compression until the glue dries. These lines often have to be run continuously because the glue systems can seize if they are not operating continuously. Additionally, the SPBs are engineered, technical pieces of packaging in their own right. For example, the handle requires reinforcing, the boxes often have additional liners placed internally, and there are several pre-press items that have to be done by the corrugator (box manufacturer).
Integrated Single Handle:
The handle is a feature making the sift-proof box compelling and the RSC box generally undesirable for the consumer. In one embodiment, the invention combines the absolute best attributes of the sift-proof box with the simplicity of design and ease of construction of the RSC.
No Stiffeners Needed:
The main concern of many handle systems on corrugated boxes is having the handles tear off. By using the glue edge of the manufacturer's seam in one embodiment of the invention, the handle is effectively reinforced. Boxes have been trialed up to 40 pounds (lbs.), but 50 lbs. appears within range of a single-wall box. In one embodiment, the invention requires no stiffeners, composite materials, or reinforcement.
Single Hand Pouring:
Neither the current RSCs or the SPBs allow for single hand pouring. The placement of the handle in one embodiment on the invention allows for balanced carrying of the box and allows for the user to lift the box to pour it in an ergonomic position where the material is balance and only one hand is needed.
Handle Cavity:
To create a clear area to insert one's hand or fingers into the handle in one embodiment of the invention, a cavity has been created using the continued flap from the manufactured seam. By extending this flap, it can be folded back to create a triangle-shaped cavity which keeps the liner out of this area and creates room for one's hand or fingers.
Completely Leak Proof:
Contrary to the name, SPBs do actually leak. The poly liner in one embodiment of the invention eliminates leakage. Liners are used in RSC but not in SPBs.
Pour Spout:
Another compelling feature of a sift-proof box is the pour spout. In one embodiment, the invention includes a novel way to add a pour spout. This pour spout allows for access to the liner. Pour spouts are used on SPBs, but BPM is not aware of any “tear-off” pour spouts being used on RSCs.
Pinch Closure:
In one embodiment, the invention integrates a pinch closure of the poly (bag) liner. By folding the top of the liner through a lower flap “cleat”, the bag top can be sealed off. This means that the bag doesn't need to be heat sealed during packaging yet will remain leak-proof. In one embodiment, the invention also includes an alternative design using an “X” shaped pinch point. After running the liner through the pinch point, the top is folder through a notch to create a full seal.
Single Handle Contact Area/Load Dispersion:
The single handle of a SPB is actually painful to use when weights of the boxes begin to exceed 20 lbs. In one embodiment, the invention manages to disperse the load over a much larger area making it far easier to carry 20-40 lbs. packages for an extended period of time.
In one embodiment, the proposed invention also allows for manufacturing with virtually no capital investment to the manufacturing lines.
In one embodiment, the invention should have functionality in markets where manufacturers and consumers need the attributes of a pail but with the cost-effective method of packing, storing, stacking, displaying, handling and shipping.
RSC boxes 200 can effectively be made “leak-proof” with a poly liner 900 as seen in
In one embodiment, the invention uses a novel way to effectively seal a poly bag or liner using just the box flaps. Most poly liners need to be sealed with a heat sealer or have a clamp or twist-tie applied to the liner. This adds time and complexity during the sealing of the poly liner. In one embodiment, the invention offers two potential designs that allow the poly liner to be pulled through a “cleat” or through an “X” shaped pinch closure 1300 of
By using either design, the top of the bag 900 is instantly accessible when the spout is opened.
Any industry that requires an efficiently stacked, stable pallet in either simple corrugated or full-color graphics could employ an embodiment of this box as an excellent delivery vehicle for its product. Powder or granules could be shipped, transported, and marketed in this format with minimal equipment investment.
The sustainable nature of compostable and recyclable corrugated boxes could make them especially desirable to industries looking to minimize their dependency on plastic pails.
