1. The Field of the Invention
The present invention is directed generally to packages, and in particular, a package that converts a parcel or a not automated flat mail piece to an automated flat mail piece.
2. Background Art
Envelopes have long been known in the art as a quick and efficient way of containing small articles for mail delivery. It has become increasingly important to move away from mailing articles that require manual sorting to mailing articles that are machine sortable. An automated flat mail piece requires little to no human intervention during processing and sorting, resulting in lower mailing costs than manually handled mail pieces.
The United States Postal Service (USPS) requires that an automated flat mail piece conform to certain mail regulations. One of the requirements to enable automated flat mail processing is that a mail piece must bend easily when subjected to a transport belt tension of 40 pounds around an 11-inch diameter turn. In order to qualify as an “automated flat,” the USPS also requires that the mail piece thickness to be no less than 0.25 inch and to not exceed 0.75 inch. If the shipper fails to meet the strict USPS requirements, it may be responsible for surcharges for mail pieces destined for automated mailing equipment that fail to meet USPS's automated flat mail requirements, and/or cause the machines to experience stoppages due to the nonconforming mail pieces. For a non-flat three dimension article, this requirement poses a challenge: to provide an envelope system that is both bendable and can hold articles securely without damage to the article. None is presently known in the art.
Thus, there is a need for a device which overcomes the limitations and drawbacks of the prior art by meeting the USPS requirements for a system that converts a parcel or not automated flat mail piece to an automated flat mail piece.
Many articles are traditionally mailed in envelopes or boxes requiring manual sorting and handling. As with most chores involving labor, higher costs are associated with the manual processing of mail. Increased costs have prompted some shippers to rethink the efficiency by which a mail piece is delivered through the USPS or even other common carriers. One of the most effective solutions for increasing the efficiency of, and reducing the cost of, delivering a mail piece is automating the process of sorting and handling the mail. However, there are strict USPS rules that must be followed in order for a piece of mail to be considered an automated flat mail piece.
In accordance with the present invention, there is provided an automated flat mail piece comprising a bendable envelope and a bendable insert tray that satisfies USPS requirements for an automated flat. The bendable envelope comprises a generally rectangular and symmetrical two-panel envelope with a sealable opening at one or both transverse edges. The envelope has two flat surfaces delineated by score lines offset from the envelope edges. The flat surfaces taper to pointed edges of the envelope edges. The envelope additionally has at least one score line, but preferably, a set of three bend-enabling equally spaced score lines disposed centrally from one transverse edge to the opposing transverse edge and also centrally from one longitudinal edge to the opposing longitudinal edge. There is provided an additional score line that intersects an envelope edge and an outermost of the set of three score lines and extends diagonally from the envelope edge to intersect the middle of the set of three score lines.
In use, the bendable insert tray is disposed inside the cavity of the aforementioned bendable envelope. The bendable insert tray comprises a generally rectangular structure having two longitudinal and two transverse edges. There is a rectangular base with a perforated line disposed centrally from each edge to its respective opposing edge, thus dividing the base into four segments. Each of the two longitudinal edges has a flap forming part of the upper insert tray lip and aligned in the longitudinal direction. Each flap has two curved exterior corners and two triangular cutouts centrally disposed widthwise across the flap with their apexes connected by a perforated score line. Each flap is integrally connected to the base by two walls extending at substantially right angle from the base. Each of the two transverse edges has a flap forming part of the upper insert tray lip aligned in the transverse direction. The flap has two curved exterior corners and two triangular cutouts centrally disposed widthwise across the flap with their apexes connected by a perforated line. The flap is connected to the base by two walls extending at substantially right angle from the base. When disposed in the envelope, the exterior edges of the insert tray's flaps preferably are contacting and aligned with the envelope's interior longitudinal and transverse edges.
In one embodiment, a mail piece is made of a card stock coated at least on one side (used as the exterior surface of the envelope) and of thickness ranging from 8 points to 30 points. In another embodiment, a mail piece is made of a non-coated card stock.
In one embodiment, the score lines on the envelope and the insert tray are scored lines. In another embodiment, the score lines on the envelope are scored lines and the score lines on the insert tray are perforated lines. In yet another embodiment, the score lines on the envelope are scored lines and the score lines on the insert tray are a combination of perforated and scored lines.
It is an object of the present invention to provide a mail piece that satisfies USPS requirements for an automated flat.
It is another object of the present invention to provide a mail piece having two parts: a bendable envelope and a bendable insert tray.
It is another object of the present invention to provide a mail piece that is reusable and/or recyclable.

There is provided a novel and previously unknown mail piece that is automated flat due to its substantially consistent thickness resulting from an erected insert tray disposed in the cavity of a mating envelope. By providing score lines on the envelope, around the periphery of the insert tray mouth and around the insert tray base, the flatness and thickness of the mail piece can be maintained. The tray's flared flaps aligning with the interior edges of the envelope, in combination with the insert tray's thickness-providing walls, provides structural rigidity to the mail piece. Thus, the mail piece both exhibits sufficient bendability to satisfy postal regulations and sufficient structural integrity to protect its contents.
The mail piece is able to negotiate bends without breaking apart or getting stuck in a mail processing unit via its combination of stress deflecting and absorbing score lines and cutouts that make it bendable. A segmented inserted tray base allows an article to be positioned away from the insert tray bend.
When an external force is applied to the outer surfaces of the envelope, insert tray thickness-providing walls have a tendency to deflect this force by rotating in the outwardly or inwardly direction with respect to the tray base with the flaps aiding in limiting or cushioning the rotation of the walls. When rotating outwardly, the walls cause the flaps to push outwardly to contact the interior edges of the envelope, making the envelope tauter thereby reducing the thickness of the envelope. When rotating inwardly, the walls cause the flaps to pull away from the interior edges of the envelope, relaxing the pressure exerted on the envelope, thereby reducing the thickness of the envelope. The beam strength of the envelope and insert tray is sized such that the thickness variation of a stuffed envelope is maintained within ¼ inch at all times.
With reference to the various figures, an automated flat mail piece 2 (“mail piece”) in accordance with the present invention is disclosed. Broadly speaking, and referring to
As will be appreciated, other ways of securing the article 3 into the insert tray may be suitably adapted and are considered within the scope of the present invention. For example, various tie arrangements or other mechanical fasteners may be employed in addition to or in lieu of the adhesive. A molded plastic sheet may be adhered to the insert tray base 16 to secure the article thereunder, or secured to another cardboard piece that is laid into the insert tray base 16. As described in detail with respect to
After being loaded with the article to be shipped, the bendable insert tray 4 is stuffed into the bendable envelope 6 via the envelope opening 5 in the direction 1 indicated.
A longitudinal elongated flap 10 is formed on each longitudinal edge of the insert tray 4. As will be described elsewhere herein, the flap 10 extends substantially perpendicularly outwardly from an edge of the insert tray mouth 49. Each longitudinal flap 10 is formed by an elongated sheet member having a curved periphery on each of its external corners 20, a triangular shaped cutout 28 at the central outside edge (in the lengthwise direction), a triangular shaped cutout 32 at the central inside edge (in the lengthwise direction), and a flap bend-enabling score line 30 connecting the apex of the two triangular shaped cutouts 28, 32. The flap bend enabling score line 30 functions as a flap bend enabling band and is substantially parallel to the insert tray bend enabling band 38a such that they cooperatively function to allow bending of the assembled mail piece 2. As will be readily appreciated, the flap bend enabling band 30 may comprise features other than score lines and/or cutouts. The opening of the triangular shaped cutouts is disposed on the inside (e.g. inner) and outside (e.g. outer) longitudinal edges of the elongated flap 10.
A transverse flap 8 is formed on each transverse edge of the insert tray 4. As will be described elsewhere herein, the flap 8 extends substantially perpendicularly outwardly from an edge of the insert tray mouth 49. Each transverse flap 8 comprises an elongated sheet member having a curved periphery on each of its external corners 18, a triangular shaped cutout 22 at the central outside edge, a triangular shaped cutout 26 at the central inside edge, and a flap bend-enabling score line 24 connecting the apex of the two triangular shaped cutouts 22, 26. The flap bend enabling score line 24 functions as a flap bend enabling band and is substantially parallel to the insert tray bend enabling band 38b such that they cooperatively function to allow bending of the assembled mail piece 2. As will be readily appreciated, the flap bend enabling band 24 may comprise features other than score lines and/or cutouts. The opening of the triangular shaped cutouts is disposed on the inside (e.g. inner) and outside (e.g. outer) transverse edges of the elongated flap 8.
Each elongated flap 8, 10 is disposed in a plane substantially parallel to a plane of the base 16, substantially aligned lengthwise to one of the longitudinal or transverse edges of the base 16, and rotatably connected to and supported by two thickness providing walls 14, 12 at the inner longitudinal edge and comprises a flap bend enabling band 24, 30 substantially centrally disposed and extending from the inner longitudinal edge to the outer longitudinal edge.

The envelope 6 further comprises bend-enabling score lines 44, stress relief score lines 46 and slope transition-enabling score lines 48. These score lines function as bend enabling bands and slope transition enabling bands. It is to be appreciated that other means of enabling bending and slope transition of the envelope may be suitably used for the bend enabling and slope transition enabling bands. Bend-enabling score lines 44 are disposed at a location where a bend is expected or desired to develop. In this configuration, a set of three equally spaced bend-enabling score lines 44 are centrally disposed from the longitudinal ends of the envelope and another set of three equally spaced bend-enabling score lines 44 are centrally disposed from the transverse ends of the envelope. The three bend-enabling score lines are preferably spaced apart from 3/16 inch to ½ inch. A stress relief score line 46 is disposed diagonally extending from each outermost bend-enabling score line 44 commencing at an envelope edge to a middle bend-enabling score line 44 to form V-shaped configuration. Referring again to
Referring to
In one aspect, the score lines are variable depth score lines such that the depth of the score is deeper in some portions, creating a perforation effect in the score line. This perforated line is particularly useful for the longitudinal and transverse tray bend enabling bands 38a, 38b and flap bend enabling bands 30, 24.
Referring to
In addition to permitting bending of the insert tray 4 along a score line 38b, 38a, a score line 24, 30 allows limited relative twisting of a flap 8, 10 about the score line 24, 30, thereby enabling a flap 8, 10 to deflect a perpendicularly applied force to one end of the flap 8, 10. A cutout disposed at each terminal end of the score lines further allows twisting of the insert tray and elongated flap.
In addition, diagonal stress relief score lines 46 are provided to cooperate with bend enabling score lines 44 to lessen the effects of a crease that may develop when the envelope 6 is bent. A stress relief score line 46 is disposed diagonally extending from an outer bend-enabling score line 44 at an envelope edge to a middle bend-enabling score line 44. When the envelope is stuffed, a slope transition-enabling score line 48 disposed parallel to, but offset from, each edge of the envelope 6 is provided to ease the transition of an envelope surface from flat 41 as delineated and enclosed by score lines 48 to the surface areas 57 outside of this flat surface and bounded by the edges of the envelope 6.
An envelope flap 42 is provided to secure the contents of the envelope 6 and also to keep the contents under snug fit. A snug fit is established when an insert tray 4 is inserted into the envelope's cavity 43 with one end of the insert tray extremity coming in contacting abutment with score line 45 to facilitate closing of the envelope flap 42 over the opening 5 to seal the envelope 6. In addition, a pair of flex-enabling cuts 40 is provided to make closing of the envelope flap 42 easier. The envelope end overlap flap 58 is affixed to the top panel 47 of the envelope 6 using adhesives.
In the embodiment shown in
In another embodiment 90 also depicted in
Some of the chief concerns in the design of mail packaging are the recyclability and reusability of the materials used. In one embodiment, a mail piece of the present invention is made of a recyclable paper product. In traditional packaging, a variety of non-recyclable packaging products are used, such as plastic bubble wraps, Styrofoam, packing peanuts, etc. Providing users with non-recyclable materials leave users with no choice but to discard these materials as landfill waste after use. Recyclability is provided with the present novel envelope and insert tray that are bio-degradable.
Traditionally, packaging materials are disposed around an article to prevent damage to the article during shipping. In order to access the article, the packaging materials need to be removed or destroyed rendering the packaging materials non-reusable in most cases. In a preferred configuration, the article is readily removed from the insert tray base by separating the article from the insert tray base. Reusability is solved by providing an envelope and an insert tray capable of withstanding stresses during processing and handling, and especially with the article holder that secures the article in place without the need for additional packing materials. The article holders allow for easy removal of the article by the recipient after shipping. Without damaging the insert tray, the mail piece may be reused for one or more shipments.
The advantages and solutions to problems in the art will now be discussed. As previously set forth, for a mail piece to be considered an automated flat, the following requirements must be met:
The problem of shipping an article in an automated flat envelope and meeting postal automated flat regulation is solved by using a bendable flat envelope having sufficient structural integrity to maintain a consistent envelope thickness and by positioning an article in the envelope such that the envelope remains bendable around curved mail processing paths by securing the article in place away from bend region.
The problem of maintaining a consistent envelope body thickness is solved by placing an erected insert tray in the envelope's cavity 43. The tray provides structural rigidity to the envelope. A flared flap aligned with each interior edge of the envelope, in combination with an envelope thickness-providing insert tray wall, provides the structure of the substantially flat envelope surfaces and maintains a substantially constant thickness at the center portion of the envelope. The thickness only decreases at or tapers to each edge as the envelope transitions from the flatness-providing surfaces to a crease at peripheral edges.
The structural integrity of the envelope is maintained under conditions of regular use, including mail handling and processing activities. When a substantially perpendicular force is applied to the panels, the thickness providing walls rotate outwardly, causing the elongated flaps to push outwardly against the interior of one of the pointed longitudinal edges and pointed transverse edges to tightly draw the bendable envelope, thereby slightly reducing the thickness of the bendable envelope and deflecting the force. When a substantially perpendicular force is applied to the panels, the thickness providing walls rotate inwardly, causing the elongated flaps to pull away from the interior edges of the pointed longitudinal edges and pointed transverse edges, relaxing the pressure exerted on the bendable envelope, thereby slightly reducing the thickness of the bendable envelope and deflecting the force.
In order for the envelope to be able to negotiate bends without breaking apart or getting stuck in a mail processing machine, the envelope must be sufficiently flat, but it must also be bendable. The problem of negotiating bends in the envelope's travel path is solved by providing score lines on the envelope and the insert tray. The score lines on the envelope around the periphery of the insert tray opening and the insert tray base also facilitate the formation of flat surfaces required for machine processing.
The problem of negotiating bends around rollers in the envelope's travel path during machine processing is further solved by providing a segmented inserted tray base on which an article can be positioned away from the insert tray bend regions. Securing the article to the insert tray base prevents the article from detaching from its position and moving into the bend region.
It will be appreciated by those skilled in the art that while the invention has been described above in connection with particular embodiments the invention is not necessarily so limited and that numerous other embodiments, uses, modifications and departures from the embodiments, and uses may be made without departing from the inventive concepts.
