Two-sided hinged repositionable note

Abstract

A two-sided hinged note comprises a generally planar sheet, an adhesive, and a hinge. The sheet has opposing front and back sides, both of which are suitable to be written upon at least in part. The adhesive, which may be pressure-sensitive and re-adherable, is on an adhesive area of the back side of the note and is capable of adhering to a surface of an item such that the sheet is flat against the surface thereby presenting the front side of the sheet facing outward from the surface. The hinge is proximate the adhesive area, wherein the hinge is operable to pivot approximately 180° to thereby present the back side of the sheet facing outward from the surface as a the sheet is approximately flat against the surface of the item.

DETAILED DESCRIPTION OF EMBODIMENTS

(18) With reference to the above-listed drawings, this section describes particular embodiments and their detailed construction and operation. The embodiments described herein are merely examples, set forth by way of illustration only and not limitation. Those skilled in the art will recognize in light of the teachings herein that there are alternatives, variations and equivalents to the example embodiments described herein. For example, other embodiments are readily possible, variations can be made to the embodiments described herein, and there may be equivalents to the components, parts, or steps that make up the described embodiments.

(19) For the sake of clarity and conciseness, certain aspects of components or steps of certain embodiments are presented without undue detail where such detail would be apparent to those skilled in the art in light of the teachings herein and/or where such detail would obfuscate an understanding of more pertinent aspects of the embodiments.

(20) FIG. 1 is an isometric drawing of a hinged note 100 according to one example embodiment. The hinged note 100 is generally a planar sheet having opposing front and back sides, each of which is suitable to be written upon to bear indicia printed or otherwise applied to the note. As shown in FIG. 1, the front side is facing upward and the bottom side faces downward on an object 200, which may be, for example, a paper such as a page of a book. The hinged note 100 comprises three sections: A writing or message portion 120, an adhesive area or anchor portion 140, and a joint, folding, or hinge portion 160. In a first, front-up or “face-up” configuration, as shown in FIG. 1, the message portion 120, the anchor portion 140 and the hinge portion 160 are generally coplanar, thereby permitting the front side of the message portion 120 to be viewed and/or written upon. The message portion 120 may be paper or any other suitable material, such as a plastic. The message portion 120 may be a conventional repositionable note or formed from a conventional repositionable note.

(21) The anchor portion 140 includes an adhesive area on the back side. This anchor portion 140 attaches the note 100 to the object 200. A suitable adhesive, such as, for example, a PSA, such as used with conventional repositionable notes, may be applied to the adhesive area. Any adhesive may be used, whereby the stickiness or tack of the adhesive is stronger or weaker, so as to suit the purpose of the note 100 and the surface characteristics of the object 200. Preferably, the adhesive has a tackiness sufficiently weak to be readily overcome manually to remove the note 100 from the surface of the item, yet the adhesive is sufficiently persistent after removal to reapply the note 100 to the same object 200 or a different surface. The adhesive may be permanent or semi-permanent but is preferably non-permanent such that the note 100 is removable from the object 200 and reusable or repositionable. The anchor portion is preferably a plastic but may be any suitable material.

(22) The hinge portion 160 is disposed between the message portion 120 and the anchor portion 140 and is connected to both the message portion 120 and the anchor portion 140. The hinge portion 160 is capable of folding or articulating at least approximately 180° to fold over the message portion 120 while the anchor portion 140 remains secured to the object 200, thereby exposing the back side of the message portion 120 approximately flat against the object 200 so that a person can read from or write on the message portion 120. When so folded, the hinged note 100 preferably rests stably in that second, back-up or face-down configuration.

(23) In some embodiments, the hinge portion 160 is a flexible material with a flexibility less than that of the message portion 120. The force required to bend or otherwise articulate the hinge portion 160 is ideally less than the adhesion strength of the adhesive on the back side of the anchor portion 140, so that folding of the hinge does not detach, and preferably does not even disturb, the grip of the anchor portion 140 to the object 200. The hinge portion 160 is preferably sufficiently flexible or bendable such that the hinged note 100 pivots readily approximately 180° about the hinge portion 160 in response to light manual force from a finger of a person or even blowing by a person. The hinge portion 160 may be a plastic material, such as a polyvinylidene chloride (commonly used as SARAN WRAP®) preferably having a thickness less than either or both of the message portion 120 and the anchor portion 140.

(24) In another embodiment, the hinge portion 160 is a line of perforations that weakens the note 100 to permit folding. The width of the hinge portion 160 may be more or less depending its construction.

(25) The anchor portion 140 may be substantially transparent or visually clear so that the object 200 underneath the anchor portion 140 is visible. In this way, any part of the object 200 can be revealed without removing the hinged note 100; instead, simply folding the note 100 over reveals a covered part of the object 200. Additionally, the hinge portion 160 may also be substantially transparent.

(26) FIGS. 2A and 2B are top views of the hinged note 100 in a first, unfolded configuration and a second, folded configuration, respectively. In FIG. 2A, the note 100 is face up in a first configuration so that the front side 120F of the message portion 120 is in view. In FIG. 2B, the note 100 has been folded or rotated about its hinge or articulating joint in the hinge portion 160 to reveal the back side 120B of the message portion 120. In that second configuration of FIG. 2B, the anchor portion 140 is covered by part of the message portion 120 proximate the hinge portion 160.

(27) FIGS. 3A and 3B are like FIGS. 2A and 2B but illustrate the hinged note 100 having a smaller anchor portion 140 and thus a smaller adhesive area. The tackiness or stickiness of the note 100 depends on several factors, including the size of the adhesive area and the type of adhesive used. Notes with less tackiness, such as due to a smaller adhesive area as shown in FIGS. 3A and 3B as compared to FIGS. 2A and 2B, may be more appropriate for use on fragile objects such as thin sheets of paper (e.g., so-called “onion skin” paper), especially if removal and reapplication of the note 100 is contemplated. The size of the adhesive area is easily adjustable to permit manufacture of different hinged notes 100 with larger or smaller adhesive areas to suit various applications and different types of objects 200. In some example embodiments, the adhesive area may be from about 30% to about 2% of the total area of the note 100.

(28) The hinged notes 100 illustrated in FIGS. 1-3 are rectangular, but such notes can be of any shape. The hinged notes 100 illustrated in FIGS. 1-3 also have a rectangular adhesive area or anchor portion 140, but the adhesive area can take any shape. The adhesive area is preferably generally proximate at least one periphery edge of the hinged note 100, but that is not required. Alternatively, the adhesive area may be in an interior portion of the note 100. For example, the adhesive area may be down the middle of the note 100 with two hinge portions—one on either side of the adhesive area—thus creating a double-flappable note. Moreover, the shape of the hinge portion 160 can also vary, but it works best if it is generally or substantially straight.

(29) FIGS. 4A and 4B are a side view and exploded side view, respectively, of one example embodiment of the hinged note 100. According to this example, the anchor portion 140 and the hinge portion 160 are formed from a common member 170. That member 170 has a thicker section that forms the anchor portion 140 and a thinner section that forms the hinge portion 160 and also attaches to the message portion 120. The member 170 may be formed integrally from the same material throughout or may be constructed from separate pieces. An adhesive 180 attaches the member 170 to the message portion 120, and an adhesive 190 is used to attach the anchor portion 140 to an object, such as the object 200 (FIG. 1). As shown in FIG. 4A, the adhesive 180 attaches the top side of the member 170 to the back side of the message portion 120, but that arrangement can be reversed (i.e., the bottom side of the member 170 attaches to the top side of the message portion 120 via the adhesive 180). The bond between the member 170 and the message portion 120 is preferably stronger than the bond resulting from the adhesive 190, so that the adhesive 190 releases before the adhesive 180. In that way, the entire hinged note 100 is removed from a foreign object, rather than the hinged note coming apart, under removal force. The adhesive 180 may be first applied to either one of the message portion 120 or the member 170.

(30) In the example shown in FIGS. 4A and 4B, the hinge portion 160 is characterized by a distance separating the message portion 120 from the anchor portion 140. That distance is preferably sufficient to prevent undue mechanical interference between the message portion 120 and the anchor portion 140 as the hinge portion 160 bends to folds over the hinged note 100. If the distance is too small, the hinged note 100 may not completely fold over and lay flat in a folded configuration. In the example construction illustrated in FIGS. 4A and 4B, the distance defining the width of the hinge portion 160 (measured horizontally as shown in FIGS. 4A and 4B) is preferably slightly in excess of the sum of the thickness of the message portion 120 plus the height difference of the anchor portion 140 relative to the height of the member 170 in the hinge portion 160. When different arrangements are used to construct the hinged note 100, a different distance may be necessary or desirable. For example, if the top of the message portion 120 attaches to the bottom of the left side of the member 170, then the width of the hinge portion 160 may be only slightly in excess of the thickness of the member portion 120.

(31) The width of the hinge portion 160 is preferably minimized to reduce movement of the message portion 120 while writing due to buckling of the weaker hinge portion 160. Too great a distance between the message portion 120 and the anchor portion 140 may cause such undesirable movement. Thus, the optimal distance, in the absence of other factors, is just enough to avoid mechanical interference or pinching while folding but little or no more than that.

(32) The anchor portion 140 and the hinge portion 160 may be constructed integrally as a two-sided tape having two thicknesses and with offset, non-overlapping areas of tape on the top and bottom. Alternatively, the anchor portion 140 and the hinge portion 160 may be constructed integrally as a one-sided tape having two thicknesses and an adhesive only on one side, generally aligned with the thicker anchor portion 140. In the latter, case, the adhesive 180 is preferably provided pre-applied to the message portion 120, such as when the message portion 120 is a conventional repositionable note.

(33) The hinged note 100 may alternatively be constructed integrally from one material that is both suitable for bearing writing and suitable to hold the adhesive 190 under the anchor portion 140. The hinged portion 160 may be a thinner section of the note's material, thus providing a more bendable/flexible portion that functions as an articulating joint.

(34) FIG. 5 is a diagram illustrating a folding operation to change the hinged note 100 from a first, unfolded configuration to a second, folded configuration, according to one embodiment. This folding operation transforms the hinged note 100 from having its front side up to having its back side up. FIGS. 6A, 6B, and 6C are diagrams illustrating three different stages of a folding operation to change a hinged note from the first, unfolded configuration to the second, folded configuration.

(35) The ways to turn the hinge note 100 over are many. When using an object to turn it over, an object may be placed underneath the message portion 120 opposite of the hinge portion 160. The object used to turn the note 100 over can also be placed at the start of the note 100 edge opposite of the hinge without going under the paper and with light force pushing the note edge forward. This action forces the paper edge forward and the note to buckle in the center of the note and then flip the edge of the note being pushed up and the object can then finish pushing the note forward and over. Also, most objects including fingers and writing utensils can be placed at the paper note edge opposite of the hinge portion 160 and the actions of flicking, flipping, pushing can be used to force the note over 180°. Light force up away from the surface may move/rotate the note 100 up, forward/backward, and then downward 180° until the note lays flat on the surface of the object 200, exposing the writeable back side of the note 100. The force required may be comparable to a light breath needed to blow out a small birthday candle flame which is accomplished all over the world by very small children to aging adults. Anyone who can lift a finger or hand off a table 6 inches and forward 6 inches can turn over the note 100. Anyone who can blow out a small birthday candle flame can turn over the note 100. Thus, the hinged note 100 may be especially useful for those having disabilities. Yet another way to turn the note over 180° is to take in one's hand or hands the object 200 to which the note 100 is attached and move the object 200 in a brisk circle arch of approximately 10 inches. The force created by that motion may turn the note 100 over automatically. This can be reversed to return the note 100 to its alternate position. Also, user can turn the object 200 upside down or sideways and the note 100 may automatically rotate over. This same rotation may be accomplished when the note 100 is stuck to a text book page and the user turns the page. This action will often times cause the note 100 to automatically rotate over.

(36) Objects that may be used to turn the note 100 include, but are not limited to, any finger or thumb and any hand; writing utensil of all shapes and sizes including pencils, pens, and markers; other paper notes or various sized paper of all thickness; one's breath as described above; the taking of a text book in of one's hand or hands and moving the book in a brisk circle arch of approximately 10 inches; turning the text book or other object 200; and placing one's tip of the tongue on the paper note edge opposite of the hinge and lifting one's head.

(37) FIG. 7 is a side view of the member 170 according to another example embodiment. In this example, the member 170 is constructed of member components 142 and 143. The component 142 is thicker and comprises part of the anchor portion 140. The component 143 is thinner and forms the hinge portion 160. A double-sided tape may be used to form the thicker component 142 and the adhesive 190 collectively. The top side of such tape adheres to the thinner component 143, which may be a plastic film. Although FIG. 7 illustrates the adhesive 180 on the thinner component 143, the adhesive 180 may instead be pre-applied to the message portion 120. In one example, the message portion 120 is a conventional repositionable note, and the adhesive 180 is the adhesive pre-applied to a portion of the back side of such a conventional repositionable note. It has been found that such an adhesive sticks well to plastic wrap, such as, for example, SARAN WRAP®.

(38) FIG. 8 is a side view of the member 170 according to another example embodiment. In this example, the member 170 is also constructed of member components, denoted as components 145 and 146 in this example. The member component 145 is a thicker piece that is the top of the anchor portion 140, whereas the thinner component 146 comprises the hinge portion 160. The thinner portion 146 is preferably flexible and bendable, whereas the thicker portion 145 provides more stability to the anchor portion 140. The components 145 and 146 may be joined by any suitable manner.

(39) FIG. 9 is a side view of the member 170 according to another yet example embodiment. In this example, the member 170 is constructed of three member components 147, 148, and 149. The components 147 and 148 sandwich the component 149, which comprises the hinge portion. The components 145 and 146 may be joined by any suitable manner.

(40) The parts illustrated in FIGS. 4A, 4B, and 7-9 may have any suitable thicknesses. For example, anchor portion 140 or components 142, 145, 147 and/or 148 may be, for example, from approximately 0.05 mm to approximately 0.08 mm thick. The hinge portion 160 or components 143, 146, and 149 may be, for example, from approximately 0.02 mm to approximately 0.03 mm thick. The adhesive 190 may be a layer that is, for example, approximately 0.01 mm thick.

(41) The hinged note 100 may be manufactured in a variety of ways. One such method is, broadly speaking, a two-part procedure. Part one involves a paper note. The back side of a note is preferably chemically treated to allow a PSA to adhere to the back side. Part two involves a single piece of tape extruded or otherwise constructed to have two sections of different thickness. Approximately two-third (or any other suitable fraction) of the width of the tape is thicker, for example, approximately 0.05 mm thick, and has PSA on its underside, while the remaining one-third is thinner, for example, approximately 0.02 mm thick and optionally has permanent adhesive applied to a portion of the top side, allowing this one-third section to be permanently or non-permanently adhered to the paper note. Alternatively, the adhesive securing the paper note to the top of the tape may be first applied to the paper note.

(42) This method of manufacture involves: (1) Tape is laid flat on a flat surface with PSA side down. (2) Paper is laid on top of the one-third thinner section of tape (permanently or non-permanent adhesive has already been applied to either the paper or the one-third thinner section of tape before laying paper down on top of the one-third section). (3) The paper and one-third section of tape are pressed together briefly and optionally exposed to infrared or other drying environment to expedite adhesive curing/drying. (4) A pre-determined amount of these completed sheets are stacked on top of each other. (5) A backing sheet can optionally be positioned as the bottom sheet. (6) These grouped sheets are then cut to desired note size and/or shape.

(43) An alternative method of manufacture, suitable for a three-part version, involves the same method as above except the tape consists of two pieces. One piece of the tape is thicker and the second piece of the tape is thinner. The thinner piece is permanently or non-permanently adhered to the thicker tape. This method of manufacture involves: (1) The thicker tape is laid flat on a flat surface with its PSA side down. (2) A thinner plastic piece is permanently or non-permanently adhered to the thicker tape with overlap on one side. (3) A paper note is laid on top of the overlap (permanently or non-permanent adhesive has preferably already been applied to either the overlap or the paper note before laying paper down on top of the overlap). (4) The paper and overlap are pressed together briefly and optionally exposed to infrared or other drying environment to expedite adhesive curing/drying. (5) A pre-determined amount of these completed sheets are stacked on top of each other. (6) A backing sheet can optionally be positioned as the bottom sheet. (7) These grouped sheets are then cut to desired note size and/or shape.

(44) HRNs, such as the hinged note 100, are useful in many ways. In general, a hinged note can be used just as a conventional repositionable note and offer the same uses. Moreover, the hinged nature of HRNs allows them to be used in other ways not readily possible with conventional repositionable notes. For example, a hinged note can be used in a flashcard mode, with questions written on the front and answers written on the back. Such flashcard hinged notes can be strategically placed in textbooks to reinforce concepts taught on the page to which the hinged note is attached. Such flashcard hinged notes can be made and placed by parents or teachers before giving a reading assignment to students, or made and placed by students as a self-study aid.

(45) FIGS. 10 and 11 illustrate two ways of collecting related sticky notes 100 together in a group. This may be useful to collect a set of notes of related information, such as phone numbers, names, and time period of when tasks were completed or initiated. With currently known repositionable notes, there is no organized way of doing this because the notes do not stick well to each other and each note needs to be lifted and unstuck completely from a preceding note in order to access information underneath. For this reason, users sometimes discard old completed notes only to find they wished they had not done so. With hinged notes or HRNs, the clear sticky strip can be stuck on top of the preceding clear sticky strip in such a way as to create one unit (a mini-book of hinged notes) where each page freely rotates 180° for convenient and quick viewing when one needs to refer to completed notes. Both the front and the back side of the notes can be viewed easily by simply turning the stack of notes. Additionally, user can date each note for more detailed referencing, if desired.

(46) FIG. 10 is a top view of three hinged notes stacked in a first arrangement. In this arrangement, the top hinged note has its front side 120F facing up, whereas the two underneath notes have their bottom sides facing up. In this way, the adhesive area of the second note sticks to the top note's back side, which may have better adhesion properties than its front side. In this arrangement, the stack of hinged notes are staggered, and each one can be flipped individually, or they can be flipped together.

(47) FIG. 11 is a top view of three hinged notes stacked in a second arrangement. In this arrangement, all three notes are face up. In this arrangement, each note is stuck to the front side 120F on the note immediately underneath it. In this arrangement, the stack of hinged notes are staggered, and each one can be flipped individually, or they can be flipped together.

(48) FIG. 12 is a perspective view of two hinged notes in an easel arrangement. In this easel arrangement, the back side of the bottom note is the display side of the easel, and the top note forms the back leg of the easel. When this easel is laid flat, the bottom note hinges at the bottom of the easel, and the top note folds over to partially cover part of the front side of the bottom note. In this way, two hinged notes or HRNs can lay flat on a page of a closed book but then be popped up when the book is opened to that page. Such an easel can be used as a study aid.
