The present disclosure is related to retail boxes and machinery and methods for making retail boxes.
Retail boxes are used widely by companies and individuals to package retail items for shipping to customers. Typically, the manufacture and assembly of a retail box is divided between two processes or machines that may be associated with different service providers or companies. Specifically, a retail box is first manufactured from raw materials, such as cardboard. This manufacturing process or step may occur using a dedicated machine that may be associated with a dedicated plant or company, which provides this service or manufacturing step. Secondly, the retail box is opened or assembled into a usable configuration. This step may be performed by a second dedicated machine, which may be located at a separate facility from the facility that had manufactured the retail box. This two-step process can lead to inefficiencies and added costs that may be born by companies or individuals who purchase a retail box.
Retail boxes are generally sold in an assembled condition. A purchaser of a retail box will typically purchase a particular quantity of retail boxes, which remain on hand for use in shipping. As can be appreciated, a company that ships a large volume of retail items may require a large inventory of retail boxes to be on hand to meet the needs of shipping various retail items. Maintaining a large inventory of retail boxes can have disadvantages, such as the need to pay taxes on the maintained inventory and space requirements associated with storing the quantity of retail boxes. Additionally, standard retail boxes are damaged easily when impacted by crumbling or tearing.
Accordingly, it would be desirable to have a system and method for manufacturing retail boxes that combine the manufacture and opening and/or assembly of the boxes together in one process. Additionally, it would be desirable to have a system and method of making retail boxes that allows retail boxes to be manufactured at the point of use; therefore, reducing the quantity of retail boxes that need to be maintained as inventory or substantially eliminating the need to maintain an inventory of boxes, thereby making available resources to more productive activities. Additionally, it would be desirable to have a system and method for manufacturing retail boxes that produces boxes that are more resilient to impact, having glued flaps that are able to bend or recoil and fully recover from impacts. Additionally, it would be desirable to have a system and method for manufacturing retail boxes where the box is made from substrate that is inline printable, allowing custom printing to be performed during manufacture of the box, leading to faster time to market. Additionally, it would be desirable to have a system and method for manufacturing retail boxes where the box is made from a substrate that is substantially thinner than materials used to make current retail boxes, which is a desirable economic and ecological feature.
The present disclosure is directed to a system and method for manufacturing retail boxes. The disclosed invention is operable to produce a retail box from paper, which is rolled on a core or provided in sheet form. Initially, a top and a bottom of the box are produced. For each of the top and bottom half of the box, a portion of paper that is output from paper rolled on a core or a sheet or a section of a sheet is applied.
In one embodiment, each of the top and the bottom halves are received in a folding plow, which folds the box portions into two complementary half-boxes. The two half-boxes are then brought together and glued at their respective sides. The overlapping box side portions are fully coated with glue when assembled, creating a strong composite structure. In one embodiment, tension is maintained on the assembled box structure and paper webbing in the direction of the webbing throughout the process and at least until the glue substantially cures. The assembled portion is now cut to length and at least one end portion of the box remains open allowing merchandise or other items to be placed in the interior of the box. Upon cutting to length, and before placing merchandise in the box, tension is applied to the assembled box in a direction substantially perpendicular to the direction of the previous tension and at a substantially right angle to the glued box side surface when the box is in an opened configuration. One of the ends may be optionally closed at this point by fully coating at least one surface of the end flaps and assembling the end flaps together. Merchandise or other items may then be placed in the box, and the remaining open box end may then be closed in a similar manner as the other end.
In another embodiment, the paper may be received in a rotary die cutting module. Here, the paper is cut into a desired shape and optionally scored and/or creased. The rotary die cutting module may cut portions of the paper webbing that will ultimately form the dust flaps, end flaps or sides of the box. After the top and bottom halves of the box have been cut and creased, the paper may then be fed into a folding plow.
In yet another embodiment, the paper webbing may be received by an inline printer. The inline printer may be used to print directly on the substrate at any point in the process.
These and other features of embodiments of the disclosure can be further understood from the following description, particularly when considered in connection with the accompanying drawings.
The present disclosure is directed to a retail box and a method of making a retail box. Retail boxes in accordance with the present disclosure are manufactured beginning with paper, which is rolled on a core, or alternatively is provided in sheet form. As used herein, a “retail box” refers to any box suitable for containing an item, for otherwise creating a desired volume, for creating a display, or for creating any other box-like structure. Two halves of the box, or “half-boxes,” are first produced, and then brought together to form a complete box. In manufacturing a retail box from rolled or sheet paper, the present disclosure allows a retail box to be manufactured and assembled at the point of use. Specifically, a shipper or retailer who requires packaging for a particular item may keep rolled paper or sheets of paper on hand, and use the paper to manufacture a box when needed.
With reference to
In another embodiment of the present disclosure, a rotary die cutting module may accept the paper webbing 106 before transmitting the webbing to the folding plow 112. The rotary die cutting module receives the paper and cuts and creases the paper to produce creases in the webbing to better enable the folding plow 112 to create creased and folded paper 114. Additionally as one having skill in the art will appreciate, the rotary die cutting module is operable to produce creases and/or cuts in the paper webbing 106 in locations that may ultimately form the dust flaps, end flaps or sides of the box. As one having skill in the art will appreciate, removal of a certain amount of material, for example, on the dust flaps resulting in a tapered flap (e.g., trapezoidal), may ease later assembly of the end flaps and dust flaps.
After two half-box blanks 114 are produced, whether in series or in parallel, the two half-box blanks 114 are brought together at the gluing station 116. In accordance with embodiments of the present disclosure, the gluing station 116 includes a glue gun operable to dispense glue or some other bonding agent. In the gluing station 116, glue is dispensed to coat one side of a side flap 216, associated with one of the half-box blanks 114. This coated side flap 216 is then brought together or joined with a corresponding side flap 216 on the other half-box blank 114. Before bringing together the two corresponding side flaps 216 of the two half-boxes, glue or some other bonding agent may also be applied to the other side flap 216, so that both side flaps 216 have glue on at least one side of the flap, preferably the side that faces or comes into contact with the side flap 216 of the opposite half-box blank 114. The bonding agent (e.g., glue, epoxy, resin, cement or adhesive) may be applied to the side flap 216 in an engineered pattern coating, which is designed to provide support and bear load for the side flaps 216. The bonding agent is preferably spread over close to all, or substantially 100% of the side flap 216. A device other than, or in addition to, the glue gun may be used to achieve substantially 100% coverage including, for example, a sprayer, a roller, a nozzle, static, a glue roller and a flat edge (e.g., for evenly spreading the glue). The glue is preferably spread over a majority of one or both of the side flaps 216, and is more preferably close to or substantially 100% coverage. One having skill in the art will appreciate that the engineered pattern coating may be a grid-like coating or matrix pattern of bonding agent that is applied to one or both of the side flaps 216. One having skill in the art will also appreciate that a combination of a grid-like coating or matrix pattern and a smooth layer may be used to achieve the necessary strength in the bonding agent layer. The glue is preferably at a low viscosity during application to either or both side flaps 216. The glue is preferably elastic when dry, and is preferably a hot-melt glue with a relatively fast curing time. The hot melt glue preferably cures as its temperature drops. One having skill in the art will appreciate a preferable cure time based on the operational requirements of the box assembly system. One having skill in the art will also appreciate the methods used to accelerate curing of the glue including, for example, cooling the machinery at a point after the bonding agent is applied using liquid coolant (e.g., water), using compressed air, using solid-state coolers, applying ultraviolet (UV) radiation.
In bringing together two half-box blanks 114, the corresponding side flaps 216 are glued together. This produces a box having four closed sides and two open sides, the open sides including end flaps 228 and dust flaps 224 of each half-box. Moreover, the two side flaps 216 forming opposite sides of the box 124 are composite box side portions, each comprising one side flap 216 of one of the half-box blanks 114, bonded to one side flap 216 of the other one of the half box blanks 114.
It is one aspect of the present disclosure that the paper or other substrate 106, 114 is held in tension in the longitudinal direction through the processes of gluing the side flaps 216. The paper or other substrate 106, 114 is preferably held in tension until the glue substantially cures. Tension may be maintained in the paper or substrate 106, 114 in the longitudinal direction using conventional methods including, for example, web handling equipment from the moment the paper or substrate 106 comes off the rolls 104 through the folding plows 112 and the gluing station 116. After the glue has cured or substantially cured, the tension in the longitudinal direction may be released.
It is another aspect of the present disclosure that the assembled paper or substrate may be cut to length in cutting station 120. One having skill in the art will appreciate the methods by which the paper or other substrate 106 may be cut, including, for example a blade, press, knife, rotary saw, band saw, reciprocating blade, laser and water jet.
The side rollers 420 are shown with their axes substantially perpendicular to the longitudinal direction. In another embodiment of the present disclosure, the rollers may be rotated up to 90 degrees or oriented so that their axes are in a range between substantially perpendicular and substantially parallel to the longitudinal direction. The rotation or orientation of the side rollers 420 other than substantially perpendicular combined with the frictional force between the roller and substrate creates a tension in the side flap 216 in a direction other than longitudinal and in a direction that is oblique to the tension in the adjacent side flap 216.
In an alternative embodiment, vacuum plates can be used to grasp (using a vacuum) the composite side flaps 412 of the box to provide perpendicular tension.
The result when the two halves 114 are assembled, as shown in
In
In one embodiment of the present disclosure, the dust flaps 224 at a corner may both depend from the end flaps 228. In another embodiment, one dust flap 224 may depend from one of the end flaps 228, and the other dust flap 224 may depend from one of the side flaps 216. In yet another embodiment, the dust flaps 224 at a corner may both depend from the side flaps 216.
It is another aspect of the present disclosure that both dust flaps 224 at a corner of the box may be glued to the end flaps 228. Specifically, glue may be applied to the dust flaps 224 with a glue gun, and the dust flaps 224 are then brought together with an end flap 228 and/or each other to effect assembly of the dust flap 224. Having the dust flaps 224 glued to the corners provides substantial strength to the box, and improves the strength at the corners as the corners absorb impacts and bear much of the load of the box. One having skill in the art will appreciate that this aspect of the present disclosure creates a four-ply portion on the end flap 228 where the dust flaps 224 are glued to the end flaps 228. In one embodiment, the dust flaps 224 at a corner may both depend from the side flaps 216.
It is another aspect of the present disclosure that both dust flaps 224 at a corner of the box may be glued to the side flaps 216. Glue may be applied to the dust flaps 224 with a glue gun, and the dust flaps 224 are then brought together with a side flap 216 and/or each other to effect assembly of the dust flap 224. One having skill in the art will appreciate that this aspect of the present disclosure creates a four-ply portion on the side flap 216 where the dust flaps 224 are glued to the side flap 216.
It is yet another aspect of the present disclosure that one dust flap 224 at a corner can be glued to an end flap 228, while a second dust flap 224 at the same corner can be glued to a side flap 216. Glue may be applied to the dust flaps 224 with a glue gun, and one dust flap 224 is then brought together with an end flap 228, while the other dust flap 224 is then brought together with a side flap 216 to effect attachment of the dust flaps 224. One having skill in the art will appreciate that this aspect of the present disclosure creates two adjacent three-ply portions. One three-ply portion is on the side flap 216 where one dust flap 224 is glued to the side flap 216, and the other three-ply portion is on the end flap 228 where second dust flap 224 is glued to the end flap 228.
It is still yet another aspect of the present disclosure that only one dust flap 224 at a corner is glued to either an end flap 228 or a side flap 216. Glue may be applied to the dust flap 224 with a glue gun, and the dust flap 224 is then brought together with one of an end flap 228 or a side flap 216 to effect assembly of the dust flap 224. One having skill in the art will appreciate that this aspect of the present disclosure creates one three-ply portion. The three-ply portion is on the side flap 216 or the end flap 228 where the dust flap 224 is glued to the corresponding side or end flap.
In the foregoing descriptions of dust flap 224 assembly, the glue applied to the dust flap 224 is preferably spread over close to all, or substantially 100% of the surface of the dust flap 224 that is to be bonded to the other dust flap 224, end flap 228 or side flap 216, and a device other than, or in addition to, the glue gun may be used to achieve substantially 100% coverage including, for example, a sprayer, a roller, a glue roller and a flat edge (e.g., for evenly spreading the glue).
In accordance with embodiments of the present disclosure, any suitable type paper may be used to manufacture a box in accordance with the disclosure. For example, size 7-8 Manila paper may be used. Additionally, paper that is less than 40 mils thick may be used to produce a box in accordance with embodiments of the present disclosure. The paper is preferably of a porous construction as this is more effective for bonding. Moreover, embodiments of the present disclosure do not require paper taken from paper rolls. In particular, sheets of pre-cut paper may be used to form each half-box.
In accordance with other embodiments of the present disclosure, the paper could be replaced by a film including, for example, PE, PET, PVC, PEEK or other polymer based films. It will be appreciated that when a non-fibrous or paper substrate is used, other chemical means may be used to bond the various sides, flaps, portions to other sides, flaps and portions. Additionally, techniques including, for example, ultrasonic welding may be used to bond the various sides, flaps, portions to other sides, flaps and portions.
In accordance with embodiments of the present disclosure, a printer may be used to print graphics, labels and/or other printed material on the continuous sheet of paper prior to the paper being cut, creased, folded, and otherwise processed by the various machine steps of the disclosure. The paper having a printed graphic may then be indexed prior to being cut, creased, folded, and otherwise processed by the various machine steps of the disclosure. One having skill in the art will appreciate that a printer may be inserted in the manufacture process at various points in the process including between the paper rolls 104 and the folding plow 112, between the folding plow 112 and the gluing station 116, between the gluing station 116 and the cutting station 120, and after the cutting station 120. A printer may also be integrated with another component, such as with a folding plow 112. One having skill in the art will appreciate that the aspect of the present disclosure that permits the use of a thin substrate permits flexibility in positioning the inline printer. Printer is meant to include single-pass or multi-pass single or multi-color apparatus, and may also include devices that apply engraving, carving, branding, stamping, embossing and watermark imprinting.
Retail boxes made in accordance with embodiments of the present disclosure are strong due to the presence of four double ply sides. The result of the two composite, double-ply sides 412 having substantially complete-coverage glue, is that its resulting composite wall strength of the box is more than the aggregate of the components. This allows boxes to be manufactured from thinner paper and/or other materials than is possible with conventional methods. Conventional methods use thicker substrates including paper, board, paperboard, corrugated fiberboard and containerboard. Accordingly, less material is used to make a box of the present disclosure than a conventional box of equivalent or greater strength. This leads to a less wasteful and more environmentally friendly product. In addition, the corners of the assembled box may feature three or four ply portions, to provide sealing and increased strength at the corners of the box. Although sometimes referred to herein as a retail box, a box created by a method or apparatus in accordance with embodiments of the present invention is not restricted to any particular application or use.
The foregoing discussion of the disclosure has been presented for purposes of illustration and description. Further, the description is not intended to limit the invention to the form disclosed herein. Consequently, variations and modifications commensurate with the above teachings within the skill or knowledge of the relevant art are within the scope of the present disclosure. The embodiments described herein above are further intended to explain the best mode presently known of practicing the disclosure and to enable others skilled in the art to utilize the invention in such or in other embodiments and with the various modifications required by the particular application or use of the invention. It is intended that the appended claims be construed to include alternative embodiments to the extent permitted by the prior art.
