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.
Containers for products that require protection from moisture generally include a moisture barrier component and a structured support component. For example, products such as cereal and printer cartridges are often packaged in a two part container that includes an inner, moisture impermeable bag, that is held within an outer cardboard box. As another example, cookies and crackers are often held in a plastic tray that is in turn placed in a moisture impermeable bag. Because these containers are formed from multiple parts, they are relatively expensive. In addition, they often incorporate non-renewable materials and can be difficult or impossible to recycle.
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. It would also be desirable to have a system and a method for providing boxes that incorporates a moisture impermeable barrier, without requiring multiple components, and/or without being formed from non-renewable materials.
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. The paper can include a moisture impermeable barrier or layer. Initially, a top and a bottom of the box are produced. The two halves of the box are interconnected. In accordance with at least some embodiments, gaps between the two halves of the box and in particular at the corners of the box can be sealed with a sealant, to provide a container or volume that is entirely or substantially impermeable to moisture. 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.
In accordance with further embodiments of the present invention, any gaps remaining after formation of the box can be sealed. For example, gaps that may occur at the corners of a completed box can be sealed using a caulk or other gap filling substance. In accordance with still other embodiments, the glue used to adhere different portions of the box to one another in the vicinity of gaps can be provided in amounts in excess of what is required to join those portions, such that the gaps will be sealed by the glue. In accordance with still further embodiments, gaps can be covered by tape, or by adhering patch pieces over the gaps. In accordance with embodiments of the present invention, the caulk or other material used to seal gaps in a completed box can itself be moisture impermeable, and may form a moisture impermeable seal with the material of the box itself. When combined with a box material that is itself moisture impermeable, a moisture impermeable or sealed container defining a sealed volume that is moisture impermeable is created.
In accordance with embodiments of the present invention, a box formed from two cooperating half-boxes is provided. Each half-box may be formed from rolled or sheet paper or other substrate material. In accordance with further embodiments of the present invention, the paper or substrate material may be impermeable to moisture. Accordingly, the substrate or paper may comprise a coated paper, a paper or substrate incorporating a moisture impermeable film or membrane, or may be formed from moisture impermeable material. Overlapping side and end portions of the two box halves can be entirely or substantially coated with an adhesive or other bonding agent. The adhesive or bonding agent can be waterproof. In addition, dust flaps can be adhered to other dust flaps, side flaps and/or end flaps. In accordance with further embodiments of the present invention, an assembled box can include sealant on at least the corners of the box. Such sealant can, for example, silicon, epoxy, or other caulk or adhesive. The sealant at the corners of the assembled box cooperates with the moisture impermeable paper or substrate material, to form a completed box that is entirely or substantially moisture impermeable.
In accordance with embodiments of the present invention, a box can be formed containing at least one insert. The insert can overlap at least one side panel and adjacent panels. In some embodiments, more than one insert can be used. The additional inserts can be used over a second side panel, or overlapping the area between a top panel or bottom panel and an end flap. These inserts can be used alone, or in combination with other inserts. Embodiments of the invention also include methods to form and attach the insert to a box blank.
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 passing 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 comprising or that will comprise a half-box blank. 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.
With reference again to
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.
In accordance with embodiments of the present invention, an amount of glue in excess of an amount required to join corresponding side flaps 216 of two half-box blanks 114 to one another is applied. In particular, excess glue can be applied at edges of the side flaps 216 near or adjacent the score lines 208 that generally define the ends of the side flaps. In accordance with still further embodiments, the excess glue may be in the form of a caulk or filling agent having adhesive properties. Moreover, the glue or caulk can be pliable, to form a seal with an adjacent end flap 228 and/or dust flap 224, to seal the corners of the assembled box 124 when the ends of the box 124 are closed.
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 half-box blanks 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 one or both end flaps 228 at that corner. Specifically, glue or another bonding agent 504 may be applied to the dust flaps 224 with a glue gun or some other means, and the dust flaps 224 are then brought together with an end flap 228 and/or each other. Having the dust flaps 224 glued to one side of each corner 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 laminated four-ply portion 824 where the dust flaps 224 are glued to the end flaps 228. The portions of an end flap 228 not bonded to a dust flap 224 can be bonded to an adjacent end flap 228. This configuration is depicted in
It is another aspect of the present disclosure that both dust flaps 224 at a corner of the box may be glued to an adjacent side flap 216, either directly or through the other dust flap 224 at the corner. Glue or another bonding agent 504 may be applied to the dust flaps 224 with a glue gun or some other means, and the dust flaps 224 are then brought together with a side flap 216 and/or each other. One having skill in the art will appreciate that this aspect of the present disclosure creates a laminated four-ply portion 824 where the dust flaps 224 are glued to the side flap 216. This configuration is illustrated in
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 504 may be applied to the dust flaps 224 with a glue gun or some other means, 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 laminated three-ply portions 832 at each corner of the box 800. One three-ply portion 832 is on or adjacent the side flap 216 where one dust flap 224 is glued to the side flap 216, and the other three-ply portion 832 is on or adjacent the end flap 228 where second dust flap 224 is glued to the end flap 228. This configuration is illustrated in
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 504 may be applied to the dust flap 224 with a glue gun or some other means, 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 various applications, it can be desirable to provide a box or container that is impervious to moisture. For such applications, embodiments of the present invention can include half-box blanks 114 comprising a top half 406 and a bottom half 408 that are formed from paper or other substrate 105 material that comprises or incorporates a moisture barrier. In accordance with further embodiments of the present invention, the substrate 105 can feature both structural and moisture blocking attributes. In order to provide a sealed enclosure, half-box blanks 114 formed from a moisture impermeable substrate 105 material can be combined with measures taken during the assembly of the box 124 to provide a complete seal against moisture. For example, as previously described herein, glue or adhesive 504 in excess of an amount needed to cover or substantially cover the surface of a side flap 216 can be applied, such that the excess amount covers any gaps that might occur at the corners of the assembled box 124. In accordance with still other embodiments, as illustrated in
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 further embodiments of the present invention, a paper incorporating a moisture impermeable layer or layers can be used to manufacture a box in accordance with the present disclosure. For example, a poly coated (e.g., polypropylene coated) paper may comprise the substrate 105 used to form the half-box blanks 114 of a moisture impermeable box 124. As a further example, the substrate 105 can comprise an impermeable material that also provides stiffness. For example, the substrate 105 can comprise plastic or mylar.
A caulk or sealant 904 applied to the corners of an assembled and closed box 124 can comprise a silicon or other material capable of bonding to adjacent sections of the box halves 114, and of providing a barrier to moisture. Alternatively or in addition, a glue or filler applied, for example to the sides 216, ends 228 and/or dust flaps 224 of a box can comprise a seal that is impermeable to moisture.
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.
Retail boxes made in accordance with embodiments of the present disclosure from substrate 105 material that is impermeable to moisture, and that have been sealed at the corners 904 of the box 124, can be used as a container for goods or materials that are preferably protected from contact with the ambient air and/or moisture, at least during transport and/or storage. For example, food, such as cereals, grains, pastas, flour, sugar or other dry goods can be transported and stored in boxes 124 as disclosed herein. Moreover, separate inner liners or bags are not required in order to provide a complete seal against the entry of moisture and/or ambient air, or to prevent the leakage of the product out of the box 124. As further examples, items that are often packaged in a plastic tray or other structure for preventing or reducing crumbling, such as cookies and crackers, and then sealed in a bag, can be packaged in a box 124 in accordance with embodiments of the present invention. As can be appreciated by one of skill in the art after consideration of the present disclosure, embodiments of the present invention can therefore provide methods and systems for transporting and/or storing food or other items that are preferably sealed against moisture and/or the ambient environment, using less materials then other packaging techniques.
The box blank 1000 with the side panel insert 1002 attached is illustrated in
Another aspect of the invention is a method for attaching the side panel insert to the box blank. The press, such as a web-fed offset press, can be used to connect the side insert panel to the box blank. Rotary technology, similar to that used in making offset printing work, can be utilized to register the insert at the correct location on the blank. The side insert panel can be added to one or both side panels. By way of example, the box blank may be printed, then the side panel inserts are added to the box blank on side panels and the dust flaps. The side panel inserts can be added to the box blank by any suitable method, including gluing or laminating. The glue can be applied in a pattern, be fully glued, cover the entire overlapping area between the side panel inserts and the box blank (over the side panels and dust flaps), or cover a portion of the area between the side panel inserts and the box blank. A vacuum roller or sheet cutting tool can be used to hold the glued insert in place on the blank until laminated. It is important to note that the side panel inserts can be attached to the box blank in a continuous process. Thus, the material that will eventually become the side insert panel can be a continuous sheet of paper attached to the box blank (before it is cut to size, but after it has been printed).
The material for the box blank can be any suitable material. In some embodiments, the box blank can be made of FDF board, recycled paper, CRB board, or the like. The thickness of the box blank can be between 12 caliber to about 20 caliber, in some embodiments about 14 calibers. The insert material can be any suitable material. In some embodiments, the insert material can be a paper board or a recycled paper. The source of the paper can be recycled paper bags. Other recycled paper materials can also be used. The insert material does not require pre-preparation to prepare the paper for printing, which can be at a lower cost than the box blank material.
After the insert is attached to the box blank, the box blank can have a thickness that is between about 5% and about 60% greater than a thickness of the reinforced box blank not comprising the insert. Thus, locations where the box blank is not reinforced with the insert can be thinner than areas where the insert is attached to the box blank. By way of nonlimiting example, the thickness of the box blank can be between about 3 and about 50 points. The thickness where the insert is present on the box blank can be between about 3 to about 50 points.
The side insert panels are attached to the box blank after it is printed, but before the box blank is cut to length or shape. A uniform box blank thickness allows for an efficient printing process. While it is possible for the printing press to accept varying box blanks with varying thicknesses, it would slow down the printing process and can cause failures when the box blank is fed through. Similarly, while it is possible for the side panel insert to be added to the box blank after the box blank is cut and sized, it would require a feed press capable of accepting a cut box blank with multiple flaps, which would increase the potential of failure for the feed of the box blank when the side panel attached to the cut box blank.
An advantage of the invention is that it reduces the material required to produce a reinforced box. The total material savings using the present method is between about 10 to about 40%, in some embodiments, about 25%. The cost saving using the present method can be between about 10% to about 35%, in some embodiments about 20%. An advantage of the method to attach the side panel insert to the box blank is that the process can be continuous, and in-line with other processes used to produce the box blank.
Another advantage is that the inserts provide two directions of strength—from front to back, and from top to bottom. By making the inserts slightly larger than the side panels on the box blank—so that it overlaps the area of the dust flaps and the top panel and the bottom panel—the strength of the box blank is increased in two directions. The amount of overlap can vary. In some embodiments, the overlap may be between about 0.1 inches and about 1 inch. In some embodiments, the overlap may cover between about 1% to about 20% of the dimension of the portion of the box panel it is covering. For example, the side panel insert may cover between about 1% to about 20% of the top panel. This added strength can be useful in not only packaging, but also in shipping the box blanks.
Cartons containing reinforced paper inserts have several advantages to non-reinforced cartons. First, the use of inserts significantly reduces the amount of board used to make most folding cartons with inserts, thereby making the use of inserts to reinforce cartons a sound business decision. By reducing the thickness of the folding carton by about 25-50% compared to load bearing material based non-reinforced cartons, the cost to produce the cartons is reduced by between 12-30%. Furthermore, the reinforced carton can be strengthened in two directions—from to back and top to bottom. This additional strength is important for products like cereal boxes that require side clamping. Cartons in general are weaker in the side to side direction, but this weakness is acceptable as there are not load bearing requirements in that direction. Furthermore, it is possible for the insert to be made of trimmings from wider master rolls of materials, or from low cost recycled papers (often used to make paper bags). Thus, the use of the inserts both reduces waste and can be manufactured at a low cost, which contributes to the advantages of using the inserts. Second, reinforced cartons have better properties, including strength, compared to non-reinforced cartons. Table 1 illustrates testing performed on reinforced cartons as compared to standard single layer cartons. As illustrated in Table 1, the strength of the reinforced carton is double that of the non-reinforced cartons. Thus, the insert can be made of a much thinner material, but still provide significant strength to the carton. Third, the process of manufacturing the inserts, and incorporating the inserts into the cartons can utilize an offset press.
