BACKGROUND OF THE INVENTION

1. Field of the Invention
The invention is related to mailers and picture frames, and more specifically, to a combined mailer and picture frame including means to locate an image relative to the viewing aperture of the frame. The invention also relates to a mailer and picture frame combination that can withstand shipping and mailing and provide a separable frame having an aesthetically pleasing appearance.
2. Description of Related Art
People often want to send photographs through the mail, whether it be to family members, friends, or others. However, there are problems with sending photographs through the mail.
Most envelopes are too soft to be used to protect photographs during transit. Unlike letters, a photograph cannot be creased or bent without permanent damage to the photograph.
Alternatively, one may frame the picture before mailing it. While the frame will protect the picture during mailing, it will greatly increase the cost of mailing the photograph.
To alleviate this problem, special envelopes have been developed for mailing pictures such as that disclosed in U.S. Pat. No. 5,740,957 issued Apr. 21, 1998. However, one problem with the frame and mailer disclosed therein is that the easels are exposed during the shipping process. It is possible that they would catch on some other item in the mail and rip or tear away. This could not only cause problems for the end receiver, but could cause problems for the U.S. Post Office. If the easels were to be pulled into an extended position during shipping, the mailer may jam the sorting machinery that the post office uses.
The frame portion of the mailer generally is formed by superimposing a front panel having a picture view aperture over a rear panel and connecting the two panels along three sides. The fourth side is left open to accommodate the insertion of a photograph into the space between the two panels such that the image in the photograph shows thorough the viewing aperture.
However, if the photograph is too small relative to the frame, it may slide side-to-side or end-to-end in the frame so that the alignment of the photograph in the aperture is an issue. In an extreme case the photograph can move within the frame so much so that an edge of the photograph shows in the aperture and a portion of the image at an opposite side of the photograph becomes hidden beneath the front panel.
Accordingly, it also is desirable to provide a combined picture frame and mailer wherein the picture is accommodated in a manner that the image is properly aligned within the viewing aperture and the photograph is precluded from shifting within the fame.
Therefore, a need exists for a combined picture frame and mailer that properly orients the photographic image relative to the viewing aperture of the frame and which maintains this orientation during shipping and subsequent set up of the frame. The combination frame and mailer also should be able to withstand the postal process, and provide an attractive separable frame. The need also exists for a combined picture frame and mailer that reduces complications in the mailing process. It is also desirable to produce a combined picture frame and mailer that is easier to manufacture than current combined picture frame and envelopes.

BRIEF SUMMARY OF THE INVENTION

Generally the present invention provides a combined picture frame and mailer having means to align the photographic image in the viewing aperture as the photograph is inserted into the frame. Once inserted, the photograph is maintained in its proper alignment so as to prevent both the end-to-end and side-to-side shifting of the photograph in the frame. The invention allows a person to insert a photograph or picture into a frame, wherein locator strips within the frame guide the insertion so the viewable image of the picture is properly located within the viewing aperture of the frame. The locator strips furthermore maintain the proper orientation of the picture during shipping and subsequent viewing.
A preferred embodiment of the present invention includes a blank divided into a series of panels. A first panel is a frame front panel. The frame front panel has a viewing aperture through which a photograph is viewed. A second panel is a frame rear panel and is connected to the frame front panel along a first fold line. The frame rear panel can include easels that may be folded outward from the panel. The easels allow the frame to be stood upright when the frame portion is detached from the mailer portion.
To form the frame the front panel is folded over the rear panel such that the first fold line defines one closed end of the frame. The frame front panel then is sealed to the rear panel along the two parallel opposite sides that run perpendicular to the first fold line. The end of the frame opposite the first fold line is left unsealed to provide an access opening for the insertion of a photograph between the front and rear panels.
Sealing of the front panel to the rear panel along the two parallel opposite sides is accomplished using two glue flaps that are connected to the rear panel along fold lines that define the opposite sides of the rear panel extending perpendicular to the first fold line. The glue flaps are first folded over the rear panel and a face of the glue flap is sealed to the rear panel. The front panel then is folded over the rear panel and sealed to the opposite face of the glue panel. This locates the glue panel between the front and rear panels along the opposite sides of the frame that run perpendicular to the open end.
The glue flaps in the folded position each have an inboard edge that together define parallel guides engageable with the opposite side edges of a photograph inserted into the frame open end. The distance between the inboard edges of the glue panels is just sufficient to accommodate the width of a picture of a given size therebetween. Accordingly the glue flaps comprise locator strips that engage the opposite side edges of a photograph in an edge-to-edge relationship to locate and maintain a side-to-side orientation of the photograph relative to the frame. This properly orients and locates the photographic image side-to-side in the viewing aperture.
The glue flaps each have an extension that extends inward one towards the other. These extensions are glued in a similar manner to each of the front and rear panels. Each of the extensions has an edge portion facing the open end of the frame. These extension edge portions are engageable with a leading edge of a photograph inserted through the open end of the frame. The distance from the open end of the frame to each of the extension edge portions is sufficient to properly locate the image of a photograph of a given size within the aperture when the picture leading edge is butted edge-to-edge against the extension edges.
A third panel forming a mailer rear panel is connected to the frame rear panel along a second fold line. A fourth panel forming a mailer front panel is foldably connected to the mailer rear panel along a third fold line. A closure flap is foldably connected to the fourth panel along a closure fold line. The closure flap can include an adhesive.
The frame may be folded over to overlay the frame front panel against the mailer rear panel. The frame and mailer rear panel may then be folded to overlay the frame rear panel against the mailer front panel, thereby protecting both the front and the rear frame panels.
The blank includes a separation line intermediate the first fold line and the second fold line to be proximal to the second fold line and located so that the mailer can be detached from the frame along the separation line. The separation line is located within the footprint of the periphery of the frame front.
The embodiment of the invention disclosed below properly positions and maintains a photograph of a given size relative to the image-viewing aperture of the frame so there is no shifting of the photograph relative to the viewing aperture during mailing. It also protects both the photograph exposed through the viewing aperture in the front panel and the easels cut into the frame rear panel. The projected markets for these combined picture frame and envelopes include retail sales to tourists and special order sales to businesses. The tourist consumer could write greeting information on the inside. The corporate client could include promotional information to clients, employees, or others.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, a combined picture frame 4 and mailer 6 is formed from a blank generally indicated at 10. The blank 10 includes a first panel 20, a first fold line 12, a second panel 24, a separation line 30, a second fold line 14, a third panel 28, a third fold line 16, a fourth panel 32, a closure fold line 18 and a closure flap 36. The blank 10 can be formed of a variety of materials including, but not limited to paper board, press board, board, composite, laminates, plastic, or corrugated cardboard.
The fold lines 12, 14, 16 and 18 are shown parallel one to the other and are located so that the panels can be folded one over another to assume an overlapping coplanar configuration. The term fold line refers to lines or creases that allow adjacent panels to fold or bend about an axis lying on the fold line. In a preferred embodiment, the blank 10 is creased so that the fold lines all bend in the same direction.
The first panel 20 forms the front of the frame and is referred to as frame front panel. An aperture 22 is cut from the frame front panel 20 and forms a window for viewing a photograph or picture subsequently placed within the frame 4. A clear plastic or film pane may be placed over the aperture 22; however, the frame 4 can be employed without the pane. The aperture 22 could be any of a variety of shapes. Examples of other shapes include ovals, circles, ellipses and heart-shaped apertures.
The second panel 24 forms the rear of the frame and is referred to as the frame rear panel. The frame rear panel 24 is connected to the frame front panel 20 along the first fold line 12. The frame rear panel 24 includes easel forming cuts 26 and corresponding access apertures. The frame rear panel 24 thus provides for the formation of easel members (represented by easel cuts 26) to orient the frame in an upright freestanding position.
The frame rear panel further includes a generally L-shaped glue flap 5 foldably attached to the rear panel wherein the fold lines 7 define the opposite side edges of the rear panel. The glue flaps extend generally perpendicular to the fold line 12 and the short leg or extension 8 of each L-shaped flap lies adjacent the fold line 12 and extends outward and away from the fold lines 7. The edges 9 of the glue flaps extend parallel to the fold lines 7 (rear panel side edges). The edges 11 of the glue flap extensions 8 are collinear one to the other and are parallel to the fold line 12 for purposes set out hereinbelow.
A first surface, or side of the blank 10 is shown in FIG. 1. Thus, a second surface, or side of the blank 10 is not visible in FIG. 1. Accordingly, the frame 4 is formed by folding the glue flaps 5 so the first surface of each glue flap is adhered flush against the first surface of the rear panel 24 as shown in FIG. 2 (the second or reverse surface of the glue flaps showing in FIG. 2).
The frame front panel 20 then is folded along the first fold line 12 as shown by the arrow 13 to lay the first surface of the frame front panel over the frame rear panel 24. The first surface of the front panel is adhered flush against the second surface of the glue flaps. In this fashion the frame front panel 20 and frame rear panel 24 are bonded to opposite surfaces of the glue flaps 5.
After folding, the edges 9 of the glue flaps will define inboard facing edges that are parallel and spaced from the adjacent edges of the viewing aperture 22. For purposes of the present invention it is important that the distance “X” between the inboard facing edges 9 is substantially equal to or at most slightly greater than the length of a given size photograph or picture. Consequently, the distance “X” is greater than the length of the viewing area defined by the viewing aperture 22.
In a similar fashion, the size of the glue flap extensions 8 are such that in the folded position shown in FIG. 2, the edges 11 of the glue flap extensions are located a known distance from the fold line 14 representing the open end of the frame. In particular, the edges 11 preferably are the located about as far from the adjacent edge of the aperture 22 as the opposite edge of the aperture is from the fold line 14.
While not shown, both surfaces of the glue flaps can be coated with an adhesive and include a strip covering the adhesive that is selectively removed to expose the adhesive for forming the frame. While alternate adhesive arrangements are possible, it is important for the present invention that substantially the entire first and second surfaces of the glue flaps be adhered respectively to the first surface of the rear and front panels 20, 24.
The sealing by the glue flaps along the two opposite sides of the frame (represented by fold lines 7) combined with the closed end at the fold line 12, leaves the end of the frame opposite the fold line 12 open. Also, since the front and rear panels 20, 24 are adhered to opposite surfaces of the glue flaps 5, a thin channel 15 is formed as shown in FIG. 9 that is as thick as the glue flaps 5. With the frame 4 being assembled in this fashion, a photograph 40 of a given size may be inserted through the open end of the frame and into the channel 15 as shown in FIG. 7.
FIG. 7 shows the photograph 40 being inserted into the thin channel between the front and rear panels 20, 24. In this respect, FIG. 4 shows that the end 17 of each glue flap adjacent the frame open end is tapered. This facilitates guiding a leading edge 19 of the photograph into the thin channel 15. Moreover, the width of the channel (as defined by the distance between the opposed inboard edges 9 of the glue strips) is about equal to the length of the photograph of the given size.
As the photograph is inserted, the opposite side edges of the photograph slidably engage edge-to-edge against the opposed inboard edges 9 of glue flaps 5. In this fashion the glue flaps comprise guides and locators that engage the opposite side edges of the photograph first to guide the photograph into the channel 15 and then to properly locate the photograph relative to the viewing aperture 22. Moreover, the edge-to-edge abutment of the photograph side edges and the glue flap edges 9 prevents any side-to-side movement of the photograph relative to the viewing aperture. Accordingly, the glue strips comprise locator strips that not only locate the photograph relative to the aperture but also maintain the side-to-side position of the photograph.
The insertion of the photograph continues until the leading end 19 of the photograph abuts the glue flap extension edges 11 as shown in FIG. 8. Given the location of the edges 11 relative to the frame open end, the abutment of the photograph leading edge against the extension edges 11 properly locates the photograph endwise relative to the viewing aperture. Accordingly, the locating function provided by the glue flaps effectively locates the photograph side-to-side and endwise relative to the viewing aperture 22 and maintains this location during subsequent mailing and viewing of the photograph in the frame.
Although the viewing aperture 22 is shown as rectangular, the aperture can have a variety of configurations such as oval, round or even an irregular shape. It is sufficient for purposes of the present invention only that the glue flaps be as described and to properly locate and maintain the position of the photograph relative to the viewing aperture so that a desirable portion of the image on the photograph is maintained in the viewing aperture.
The frame rear panel 24 as shown in FIGS. 1 and 2 includes a separation line 30 intermediate the first fold line 12 and the second fold line 14, and located proximal to the second fold line. Upon the front frame panel 20 overlaying the rear frame panel 24 as described above, the separation line 30 is within the periphery of the front frame panel. The separation line 30 provides a line of weakness in the blank 10, which is weaker than the fold lines.
The separation line 30 can be a perforation line where the blank 10 is sufficiently weakened to allow the material to separate easily. The separation line 30 allows the frame 4, including frame front panel and frame rear panel (20,24) to be detached from the mailer 6 (panels 28, 32). After the frame 4 is formed, the separation line 30 is located within the footprint of the periphery of the frame front panel 20, so that an edge formed by the separation line 30 is not visible to a viewer of a picture in the frame 4. The separation line 30 does not have to be perforated, but may be any line where the material has been weakened to allow separation of the panels along the separation line 30 prior to any separation along a fold line.
The third panel 28 forms a mailer rear panel and is foldably connected to the frame rear panel 24 along the second fold line 14. Preferably, the mailer rear panel 28 is a contiguous uninterrupted panel. That is, the mailer rear panel 28 is free of cuts, perforations or apertures. The fourth panel 32 is a mailer front panel and is connected to the mailer rear panel 28 along the third fold line 16. The first side of both the mailer panels 28, 32 can contain areas for writing or pasting a message or other information. The second side of the front mailer panel can include a mailing label as seen in FIG. 6.
The closure flap 36 is connected to the mailer front panel 32 along closure fold line 18. An adhesive strip or seal 34 is formed on the closure flap 36 so that the flap will bond to the second side of the mailer rear panel 28 when the mailer is prepared for mailing. The preferred embodiment includes a peel and seal type strip.
The closure flap 36 further includes a zip strip 38 is located between closure fold line 18 and the adhesive strip 34. The zip strip allows the mailer 6 to be unfolded without damaging the retained photograph. Alternatively, the closure flap 36 can include a tear strip, tear line or tear lines for breaking the closure flap. That is, the closure flap 36 is sacrificed to open the sealed mailer.
To prepare the present invention for mailing, a user inserts a picture into the open end of the frame and into the thin channel 15 between the front and rear frame panels 20, 24 as described above. The frame 4 can then be folded over onto the rear mailer panel 28 to locate the second surface of the frame front panel flush against the first surface of the first mailing panel 28.
In particular, FIG. 3 shows the frame 4 folded along the fold line 14 so the frame front panel 20 overlays and is flush against the mailer rear panel 28. At this point the rear panel 24 and the easel cuts 26 are still exposed. To protect the easel cuts, the frame 4 and the mailer rear panel 28 can then be folded over the fold line 16 and onto the mailer front panel 32 as shown on FIG. 4. In this fashion, the front and the rear frame panels 20, 24 are sandwiched between and are accordingly protected by the mailer front and rear panels. That is, the panels form a stack where the panels are superimposed one on another, the stack having in order, the mailer front panel 32, frame rear panel 24, frame front panel 20 and the mailer rear panel 28.
Finally, the closure flap 36 is folded over and sealed to the second side of the mailer rear panel 28 as shown in FIG. 5.
The recipient of the mailer can open the mailer by pulling the zip strip 38. The mailer 6 can be unfolded along the second and third fold lines 14, 15. The recipient can then read or access any material attached to the first side of the mailer front and rear panels 20, 24. The frame 4 is detached from the mailer along the separation line 30, with the newly formed edge being behind, hidden by the frame front panel 20. The easels are extended from the easel cuts 26 so the framed picture becomes self-supporting on a table or mantel.
For purposes of manufacturing the combination frame and mailer of the present invention, printing, foil stamping, die-cut shapes and embossing can be provided on either side of the panels. In a preferred embodiment the second side of the frame front panel 20 is foil-stamped.
The blank 10 is cut from a sheet of desired material. One method of accomplishing this is by die-cutting. The aperture 22 is also created in the first panel 20. Preferably these methods leave relatively smooth borders that are aesthetically pleasing to the eye. That is, the edges are free of scallops or shards. In addition, the easel cuts 26 and associated apertures can be similarly formed in the frame rear panel 24.
After the blank 10 is completely cut, it may be folded and glued in a single one pass through an assembly line. That is, each of the manufacturing processes are applied to a single side of the blank 10. Thus, the blank 10 can be converted to the configuration of FIGS. 2 through 5 without having the blank flipped or inverted.
Rather than applying adhesive and cover strips to both sides of the glue flaps as described hereinabove, an adhesive may be applied only to the first surface of the glue flaps shown in FIG. 1. After the glue flaps are folded over and adhered to the rear panel 24 and adhesive can be applied to the reverse surface of the glue flaps and the frame front panel 20 can be automatically folded over onto the frame rear panel 24, where adhesive on the glue flaps bond the panels together. Typically, the product can be shipped to retail distribution or consumers in this configuration.
The present construction can be used with any relatively thin substrate such as photographs. However, drawings and sketches, invitations, or awards can be employed with the combined frame and mailer.
The combined frame and mailer provides an integral one piece frame and mailer, wherein a photograph can be retained and located within the frame. Text, messages or inserts can be connected to the mailer, and the integral mailer can then be folded and sealed about the frame 4 to protect the front and rear of the frame during the transportation process. As the front and mailer panels have a foot print at least as large as the front frame and rear frame panels, the frame is protected. The sealed device can be readily opened by severing the closure flap without damaging the mailer or the frame. Subsequently, the mailer can be separated from the frame along an effectively hidden separation line.
Further protection of the frame during mailing can be provided by adding retainer flaps (not shown) along the edges of the mailer rear panel 28. After the frame 4 is folded over the mailer rear panel as described above, these retainer flaps are folded so as to overlay the side edge portions of the frame rear panel. Now, when the frame 4 and mailer rear panel is folded over the mailer front panel 32, the retainer flaps will be captured therebetween to provide a more secure package for mailing.
While preferred embodiments of the invention have been shown and described with particularity, it will be appreciated that various changes and modifications may suggest themselves to one having ordinary skill in the art upon being apprised of the present invention. It is intended to encompass all such changes and modifications as fall within the scope and spirit of the appended claims.
