Description
FIELD OF THE INVENTION
This invention relates generally to sheet holders, and more particularly to folders for holding materials having overlapping windows disposed on the folder for targeted display of title information.
BACKGROUND OF THE INVENTION
Documents such as promotional packages are commonly prepared for distribution and later retrieval by others. It is often desirable to bind these documents in a holder that presents a visually pleasing appearance while facilitating the review of the contents contained therein. It is known to provide folders with internal pockets for receiving documents and securing the same between the protective covers of the folder. To facilitate the organization and identification of the documents contained within the folder, content identifiers such as labels are generally affixed to the front cover of the folder.
Various forms of content identifiers are known in the art and have been incorporated into folders. The simplest form is attaching inscribed self-adhesive labels to the front cover of the folder. Also commonly used are transparent plastic materials, typically rectangular in shape that are either heat sealed or adhesively attached to the spine or the front cover into which a label can be inserted.
Another known alternative is to form front and back covers of transparent sheets of material. A folder of this type displays the top sheet of the document contained therein as a title sheet, which may easily be prepared using laser printing technology.
U.S. Pat. No. 5,882,038 is directed to a document folder having front and back covers and interior pockets. The front cover of the folder is formed with title viewing windows. A title backing has tabs that secure a sheet of standard sized paper and engages the front cover to display the printed information on the sheet of paper through the windows. The backing is shown as an extension flap to the folder and folded over the front cover. Alternatively, the backing sheet is a separate sheet and is insertable within the interior pocket on the front cover.
Further, U.S. Pat. No. 3,107,043 discloses a filing folder for holding security certificates. The folder has front and back covers pivotably connected along a spine. A large window is centered over the front cover. An insert sheet having a small window centered thereon is insertable between the front and back covers such that when the folder is closed, the small window is exposed entirely by the large window of the front cover. The insert sheet is substantially smaller than the front and back covers, and pressure sensitive tapes are used to secure the insert sheet over a security certificate to ensure that only the name of the owner of the certificate is displayed.
Also, U.S. Pat. No. 5,031,935 is directed to a book with apertures disposed on the comers of the pages contained inside. The apertures overlap to display images affixed to the insides of front and rear covers of the book.
SUMMARY OF THE INVENTION
The present invention is directed to a sheet holder having a first panel defining a first window with a first window area and a second panel defining a second window with a second window area. The first and second panels are joined by at least one hinge, such that the first and second panels are foldable about the hinge to a folded position with the first panel disposed over the second panel. In the folded position, the first and second windows arc in overlap with each other such that the first window area overlaps substantially less than the entire second window area. A display holder having a pocket is disposed on the second panel for receiving a display sheet. The second window is configured to display a display portion of the display sheet held within the pocket, and the first window is configured to display less than the entire display portion.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1 and 2
, a preferred embodiment of a sheet holder
10
, such as a report cover or a folder, is shown having a base sheet
12
, which preferably is of a unitary construction and defines outer edges
14
,
16
,
18
and
20
. Specifically,
FIG. 1
shows an interior surface
22
of the assembled folder
10
when the folder
10
is partially open, and
FIG. 2
, in general, illustrates the preassembled base sheet
12
as a blank. When the folder
10
is assembled, elements toward the bottom of the drawings in
FIG. 2
are folded inwards toward the interior surface
22
of the folder
10
, as will be described hereinafter.
Preferably, the base sheet
12
includes first and second score lines, or alternatively hinges,
24
and
26
, extending generally longitudinally between the set of oppositely disposed edges
18
and
20
. Base sheet
12
is folded along score lines
24
and
26
to form three panels
28
,
32
,
36
, which preferably form a front cover
30
, a back cover
34
, and a side extension
36
. The side extension
36
and the back cover
34
may alternatively be a part of the same panel or as an extension thereof. Panels
28
and
32
include an exterior surface
40
, facing the exterior of the folder
10
when the folder
10
is in a closed configuration. Similarly, the panels
28
and
32
include interior surface
22
, facing the interior of the folder
10
when the folder
10
is the closed configuration or position. In contrast, both of the interior and exterior surfaces
22
and
40
of the side extension
36
face the interior of the folder
10
when the folder
10
is the closed configuration.
The folder
10
is preferably dimensioned to accommodate documents
38
of standard size sheets of papers with sufficient clearance to protect the document contained therein from external elements. An example of such sheets of paper for the document
38
is the standard letter size, 8½×11 inch, A4, or legal size. Accordingly, the dimensions of the front cover
30
and back cover
34
must be sufficient to fully cover the contents stored therebetween. The folder
10
has a lateral length D1 preferably extending from outer edge
14
to outer edge
16
, and a longitudinal length D2, extending from outer edge
18
to outer edge
20
. Preferably the longitudinal length D2 of the holder
10
provides a clearance of at least about ⅛ inches on all sides for the documents contained therein. Preferably the lateral length D
1
is sufficient to accommodate the preferred dimensions of the front cover
30
, back cover
34
and the side extension
36
. The front cover has a lateral dimension D3, extending from outer edge
14
to score line
24
. Dimension D3 is preferably sufficient to provide a clearance of at least about ⅛ inches on all sides of the document contained therein. The back cover
34
has a lateral dimension D4, extending between score lines
24
and
26
. Preferably D4 is slightly larger than D3 to ensure proper folding of the front cover
20
toward the back cover
34
in an overlapping assembly. Side extension
36
has a lateral dimension D5, extending between score line
26
and outer edge
16
. The relationship of dimension D5 in relation to the other elements of the holder will be discussed in detail hereinafter.
The base sheet
12
preferably has a bottom extension or base flap
42
, best seen from the vantage of the unassembled folder
10
in FIG.
2
. Base flap
42
is disposed along outer edge
20
and is adjacent to the panel
32
of the folder
10
. Preferably, the base flap
42
is foldable in an overlapping association with the interior surface
22
of the panel
32
. Most preferably, the base flap
42
is integrally constructed with the base sheet
12
and adjacent to the panel
32
, defining a score line or flap hinge
44
. The base flap
42
is foldable in an overlapping assembly with the interior surface
22
of the panel
32
of the folder
10
. Folding the base flap
42
over the interior surface
22
of the panel
32
forms a pocket
46
therebetween, for retaining sheets of the document
38
. In an alternative embodiment, the lateral edges of the flap
42
can be secured to panel
32
to close the edges of the pocket.
As shown in
FIGS. 1 and 2
, the base flap
42
preferably has slightly tapered lateral sides, extending from flap hinge
44
. Other shapes of the base flap
42
, however, may also be used, such as triangular, and securing flaps can be formed on either side of the base flap and securable with adhesives to fix the sides of the base flap
42
to the interior surface
22
of the panel
32
to form a pocket, or other sheet holders.
The base flap
42
has a longitudinal dimension D6, extending from the score line
44
to the outer edge of the flap, and a lateral dimension D7, extending from the lateral edges thereof. Dimension D7 is preferably slightly less than dimension D4 of the back cover
34
to facilitate folding of the covers
30
and
34
and side extension
36
, ensuring smooth overlapping engagement of these elements. Dimension D6 can be any length, but it is preferred that dimension D6 be less than longitudinal dimension D2 of the base sheet
12
. The dimension D6, however, must be sufficient to properly hold the documents
38
contained therein. The considerations in selecting the proper dimension D6 include size and thickness of the document contained therein and cost of materials for manufacture. Preferably, the longitudinal dimension D6 of the base flap
42
is less than {fraction (1/2 )} and greater than ¼ of the longitudinal dimension D2 of the base sheet. Most preferably, the longitudinal dimension D6 of the base flap
42
is about ⅓ of the longitudinal dimension D2 of the base sheet
12
.
The panel
28
also includes a first window
48
disposed between outer edge
14
and score line
24
. First window
48
has a first window area
49
and can be positioned anywhere on the front cover
30
, but preferably, the first window
48
is disposed in the outer lateral half of the panel
28
, closest to outer edge
14
. Most preferably, the first window
48
is approximately centered both laterally and longitudinally within the first outer half of the panel
28
. The side extension
36
includes a second window
50
, which may be positioned anywhere on the side extension
36
, but preferably centrally disposed between score line
26
and outer edge
16
. The second window
50
defines a second window area
51
. Preferably, the second window area
51
is greater than first window area
49
.
The positions of first and second windows
48
and
50
are coordinated such that when the folder
10
is in an assembled position with the side extension
36
folded over the interior surface
22
of the panel
32
and the front cover
30
similarly folded thereafter, exposing only the exterior surfaces
40
of the folder
10
, the first and second windows
48
and
50
are in overlap. The lateral position of second window
50
is preferably limited to the lateral dimensions D5 of the side extension
36
and the longitudinal dimension D2 of the base sheet
12
. Accordingly, the first window
48
is so positioned, within the first lateral half of the panel
28
, to accommodate the size of the side extension
36
. Preferably, the first and second windows
48
and
50
are aligned such that the first window
48
covers a portion of the second window
50
when the folder
10
is closed. Most preferably, the first and second windows
48
and
50
are aligned such that the first window
48
is completely contained within the boundary of the second window
50
when the folder is closed. Second window
50
, however, may also be positioned to extend beyond the side extension
36
.
As shown in
FIG. 2
, the first window
48
has a lateral dimension D8 and a longitudinal dimension D9, and the second window
50
has a lateral dimension D10 and a longitudinal dimension D11. Preferably lateral dimension D8 of the first window
48
is less than lateral dimension D10 of the second window
50
, and longitudinal dimension D9 of the first window
48
is less than longitudinal dimension D11 of the second window. The correlations between the size of windows
48
and
50
will be discussed in greater detail hereinafter in relation to the assembly and use of folder
10
. Also, windows
48
and
50
are shown having a curved longitudinal outer edges to provide a more visually pleasing appearance. Windows
48
and
50
having straight sides, however, are equally suitable. Additionally, windows
48
and
50
may have a circular shape any other non-rectangular shape. The shape of the first window
48
preferably corresponds to the shape of second window
50
, but alternatively may be a different shape.
First and second windows
48
and
50
may be cut-outs on base sheet
12
, or if base sheet
12
is formed of a polymeric material silk-screened for an opaque appearance or an actual opaque polymeric material, the windows
48
and
50
may be clear portions of the polymeric material without the application of the silk-screen. Additionally, in the case of cut-outs, windows
48
and
50
may be covered with a transparent material to provide protection for contents exposed through the windows
48
and
50
.
The base sheet
12
further includes a display holder
51
shown in
FIG. 2
as a pocket panel
52
. The pocket panel
52
is similarly constructed as the base flap
42
and is in an overlapping condition with the interior surface
22
of the side extension
36
. Most preferably, the pocket panel
52
is integrally constructed with the base sheet
12
along outer edge
20
adjacent to the side extension
36
and is defined by a second base score line
54
. The pocket panel
52
is foldable along score line
54
into the overlapping assembly with the interior surface
22
of the side extension
36
of the folder
10
, forming a pocket
60
therebetween. Preferably, the pocket panel
52
is constructed with securing flaps
56
extending along the lateral sides of the pocket panel
52
. In the preferred embodiment, score lines
58
are defined at the interface between the securing flaps
56
and the pocket panel
52
.
The pocket panel
52
has a lateral dimension D12 and a longitudinal dimension D13. Lateral dimension D12 of the pocket panel
52
is preferably less than the lateral dimension D5 of the side extension
36
to ensure proper securement of the pocket panel
52
thereto. Additionally, the longitudinal dimension D13 of the pocket panel
52
is preferably less than longitudinal dimension D2 of the base sheet
12
to prevent the pocket panel
52
from protruding beyond the outer edge
18
. The correlation of the lateral and longitudinal dimensions D12 and D13 of the pocket panel
52
with respect to the other elements of folder
10
will be described in greater detail hereinafter. The display holder
51
is shown as a pocket panel
52
forming a pocket
60
. Other devices for holding displays are also suitable, including, clips, releaseable adhesives, tabs, and velcro strips.
A title sheet
62
, as shown in
FIG. 3
is receivable within the pocket
60
containing display material
64
. Display material
64
may be disposed on the title sheet for identifying the content of the folder
10
. Display material
64
is positioned on the title sheet
62
such that when the title sheet
62
is inserted within the pocket
60
, the display material
64
is displayed through the second window
50
. Most preferably, the title sheet
62
corresponds to the size of the document stored within the folder
10
. A user may prepare the display of the title sheet
62
for the folder
10
along with the document for storage therein. Display material
64
is preferably divided into two portions,
66
and
68
. The first portion
66
of the display material
64
preferably contains main heading type of information, while the second portion
68
of the display material
64
contains subheading type of information.
Referring to
FIG. 2
for a preferred illustration of the assembly of the folder
10
according to the preferred embodiment. As stated previously, the folder
10
is preferably constructed from a single sheet, stamped into the unassembled configuration, having panels
28
and
32
, side extension
36
, base flap
42
and pocket panel
52
with securing flaps
56
. The base flap
42
is folded along fold line
44
toward the interior surface
22
of the panel
32
of the folder
10
. The securing flaps
56
are folded along fold lines
58
toward the pocket panel
52
. Preferably adhesives
70
are applied to the surface of the securing flap
56
opposed to the pocket panel
52
. The pocket panel
52
is thereafter folded along fold line
54
toward the side extension
36
, allowing the adhesive to secure the securing flap
56
to the side extension
36
and forming the pocket
60
with the interior surface
22
of the extension panel. Other securing methods, including stitching, taping, welding, and stapling, are also suitable. A completely assembled folder
10
of the preferred embodiment according to the present invention is shown in
FIGS. 1 and 5
.
The sheet holder
10
may have slightly curved outer edge
14
to the front cover
30
with rounded corners to further improve the overall appearance and durability of the folder
10
. Similarly, the bottom flap
42
may be slightly tapered extending from edge
20
and have rounded comers. The folder
10
of the present invention may be constructed of a number of materials to protect the contents contained therein. In view of providing ease of manufacturing and minimizing costs while achieving greater flexibility of usage, the base sheet
10
is preferably fabricated from a single sheet of material constructed of typical stiff paper, card board, bristol board or plastic. The panels
28
and
32
and side extension
36
, however, may also be individual pieces pivotally connected along score lines
24
and
26
. The card board may be opaque, plastic coated or textured. The base sheet
10
may also be constructed from a transparent sheet silk-screened into an opaque sheet except for the first and second windows for displaying information therethrough. Most preferably, the base sheet
10
is constructed from stiff paper.
As stated above, the various dimensions of the elements of the folder
10
are preferably correlated and mainly dependent upon the dimension of the document
38
contained therein. For example, the lateral dimensions D3 of the front cover
30
is preferably greater than the lateral dimension of the document
38
contained in the folder
10
, providing protection thereof. Most preferably, the lateral dimension D3 provides a clearance of about ⅛ inch on both lateral sides of the document
38
. Accordingly, to accommodate proper placement of the front cover
30
of the folder
10
in a closed configuration, the lateral dimension D4 of the back cover
34
is preferably greater than the lateral dimension D3 of the front cover
30
.
As stated previously, the title sheet
62
is preferably prepared at the same time as the document
38
, having the same overall dimensions. Accordingly, the lateral dimension D12 of the pocket panel
52
preferably corresponds to the lateral dimension of the title sheet
62
and document
38
, to ensure that the title sheet
62
is properly received within the pocket
60
. Preferably, the lateral dimension D12 of the pocket panel
52
is about ¾ of the lateral dimension of the title sheet
62
. More preferably, the lateral dimension D12 of the pocket panel
52
is between 40% to 60% of the lateral dimension of the title sheet
62
. Most preferably, the lateral dimension D12 of thc pocket panel
52
is about ½ of the lateral dimension of the title sheet
62
, allowing the title sheet
62
to be folded longitudinally in half and inserted within the pocket
60
.
The dimensions of windows
48
and
50
will now be described in relation to the display information
64
on the title sheet
62
. As stated previously, the display information
64
is preferably divided into first and second portions
64
and
66
. As also previously stated, the windows
48
and
50
are preferably aligned with respect to each other and positioned on the folder
10
such that when the folder
10
is in a closed configuration, the first window
48
is completely contained within second window
50
. Windows
48
and
50
may, however, only be partially aligned. It is preferred that only the first portion
66
of the display material
64
is displayable through the first window
48
when the folder is in the closed configuration. Upon opening the folder by turning the front cover
30
, both portions
66
and
68
of the display material
64
are displayable through the second window
50
, which is shown when the front cover
30
is in the opened configuration.
As a non-limiting example of the dimensions of the most preferred embodiment, a folder
10
constructed according to the present invention to accommodate standard 8½×11 inch sheets of paper has a front cover
30
with dimensions about 8⅞×11⅞ inches, a back cover
34
with dimensions about 9⅛×11⅞ inches, and the side extension
36
with dimensions about 4⅝×11⅞ inches. The pocket panel
52
preferably has a lateral dimension less than the side extension
36
, about 4⅜×11⅞ inches. The bottom flap
42
has a dimension sufficient to secure the sheets of document
38
stored within the folder
10
, preferably with a dimension about 8⅞×4¾ inches. The title sheet
62
is preferably the same as the sheets of document
38
contained within the folder
10
and is about 8½×11 inches. The first window
48
is preferably 2¾×1¼ inches and is positioned about 1½ inches from outer edge
14
and 5⅛ inches from outer edge
18
. Similarly, the second window
50
is preferably 3×5½ inches and is disposed about ⅞ inches from outer edge
16
and about 5 inches from outer edge
18
.
FIGS. 5-7
show the steps of using the folder
10
of the present invention for displaying information. The display material
64
is disposed on the title sheet
42
preferably using conventionally available laser printers. Most preferably, the display material
64
is printed on a longitudinal half of the title sheet
62
. The title sheet
62
containing display material
64
is folded longitudinally in half and inserted within the pocket
60
with the display material
64
displayed through the second window
50
, as shown in FIG.
4
. The document
38
to be contained within the folder
10
is placed between the bottom flap
42
and the panel
32
and between score lines
24
and
26
and preferably in substantial alignment therewith. The bottom flap
42
holds the document
38
in place within the folder
10
. The side extension
36
is folded toward the panel
32
along score line
26
, as shown in FIG.
6
. The side extension
36
further secures the document
38
within the folder
10
, minimizing lateral movement of the document.
FIG. 6
illustrates the display of first and second portions
66
and
68
of display material
64
displayed through the second window
50
of the side extension
36
. Thereafter, the panel
28
, or front cover
30
, is folded over toward the panel
32
along score line
24
, as shown in FIG.
6
.
FIG. 7
illustrates the first window
48
displaying only the first portion
66
of the display material
64
displayed through the second window
50
. Accordingly, a visually pleasing and functionally effective presentation is obtained with the folder of the present invention. Additionally, as the folder
10
is retrieved for view by a subsequent user, the first portion
66
of the display material
64
, preferably containing the main heading, is displayed through the first window
48
, as shown in
FIG. 7
, with the remaining second portion
68
of the display material
64
covered by the front cover
30
. In the closed configuration, the sheets of document
38
are contained within pocket
46
secured by bottom flap
42
and side extension
36
. Upon opening the front cover
30
, the remaining second portion
68
of the display material
66
, a subheading or other information, is shown through the second window
50
in addition to the first portion
66
of the display material
64
, as shown in FIG.
6
. The use of standard sized paper allows users the option of easily printing title and caption information using conventionally available laser printers. By selectively positioning the printed information
64
on the title sheet
62
, the folder
10
of the present invention allows a user to segment the display of the information, such as exposing only a title or heading in the first portion
66
when the folder
10
is closed and exposing more detailed description of the materials contained in the folder
10
in portion
68
of the display material
64
when the front cover
30
is open, resulting in a folder
10
with a great visual appearance and not the same time functionally desirable.
One of ordinary skill in the art can envision numerous variations and modifications to the invention disclosed herein. For example, the adhesive strip of the fourth panel of the spine may be applied separately by the user at the time of assembly, eliminating the need of a protective cover, or the spine may be constructed as a separate sheet from the back cover and attachable thereto. All of these modifications are contemplated by the true spirit and scope of the following claims.
