Record pad

Abstract: A record pad (1) comprising at least two adjacent record assemblies (3,4), each comprising a plurality of sheet sets, each sheet set comprising at least one removable top copy sheet (3) and an underlying record copy sheet (4) in which the top copy sheet (3) lies in close juxtaposition to the underlying record copy sheet (4) and bears a strip of repositionable adhesive, applied adjacent one side edge, easily detachable connected to said record copy sheet and in which said side edge of the copy sheet and the corresponding edge of the record copy sheet provide a securing edge margin, which securing edge margins are secured to securing edge margins of sheet sets of said record assembly lying on top or below, and said securing edge margins are substantially free from said strip of adhesive.

Description: This invention is concerned with a record pad according to the preamble of claim 1. EP-A-0.325.057 gives a description of such a record pad. Both the record copy sheet and the copy sheet have a securing edge margin at the corresponding side, which carry a perforation inserted with a ring binder element, such that the superposed sheets are mutually secured assembled into said record pad. The strip of repositionable adhesive of said copy sheet is provided at the edge adjacent and parallel to said securing edge margin, and covers said securing edge margin as well. Said record pad is intended to be used with the securing edge margin at left hand position for the writer. Because of this, both said securing edge margin and said strip of repositionable adhesive are provided at the left side-edge of said copy sheet. A set of three adjacent copy sheets parallel to the longitudinal direction of said securing edge margin is illustrated, which set is mutually secured by way of a tear-perforation extending along the respective upper- and lower edges of said copy sheets, the corresponding record copy sheets are mutually integrated and carry no tear-perforation between them, corresponding to the tear-perforation between the respective copy sheets. To save material, it was proposed later on, to eliminate the securing edge margin of the copy sheet, saving adhesive for the adhering strip as well. The object of the present invention is to improve the assembly of the sheet sets and the handling of the record pad, maintaining the material savings compared to the record pad according to EP-A-0.325.057. This object is met with the combination of features as indicated in claim 1. Now it is more convenient to remove the copy sheet from the record pad leaving its securing edge margin secured to said record pad, while less adhesive is used. On the other hand, by providing both the copy and the record copy sheet with a corresponding securing edge margin substabtially free from adhesive, is it possible, to secure the multiple of superposed sheet sets to each other, for instance with adhesive, staples or a ringbinder-element, without the risk of sliding of sheet sets out of position during securing etc., for assembling the record pad. Furthermore it is advantageous if the strip of adhesive extends spaced from the respective tear-perforation between the copy sheet and its corresponding securing edge margin or between two respective copy sheets. The spacing must be such that, if a copy sheet is removed from the record pad, the copy sheet comes free from the underlying record copy sheet and the tear-perforation is torn not at the same time. A spacing of 1 to 5 mm., preferable 2 mm. is convenient. With a strip of repositionable adhesive is meant a strip of non-drying, more or less tacky adhesive, which is permanently secured to the copy sheet and is adapted to be adhered several times to a substrate, to be repetitive removable. The general concept of record copy with permanent adhered strip of repositionable adhesive is disclosed in CH-B-452479. When assembling such a record pad with the aid of non-drying adhesive, the top edge of each individual sheet is mechanically pressed with its underside, which receives adhesive, to the smooth upper surface of the other sheet, which does not take up adhesive. The individual sheets are thereby bonded together but they are not permanently fixed together, that is to say they are not glued together but can be separated one by one by hand. When a sheet is removed, the adhesive is left on the underside of the sheet such that the sheet which has been removed can be fixed by light finger pressure to an other surface without the use of fresh adhesive. Adhesives and paper useful in making such products are well-known in the particular art. European patent application nr. 88301727.9 discloses a record pad having a plurality of sheets arranged in a stack with transfer material positioned between each of the plurality of sheets and with a strip of repositionable adhesive positioned at the top edge of each sheet to secure it to the adjacent sheet. GB-B-2214131 discloses a path with record sheets and removable sheets disposed in pairs. Transfer material is positioned between the record sheet and the removable sheet of each pair and a strip of low tack adhesive is provided along the marginal edge of the removable sheet with a perforation line in the removable sheet within the strip of low tack adhesive. Embodiments of a record pad in accordance with the present invention will now be described by way of example with reference to the accompanying drawings, wherein: fig. 1 is a perspective view of a record pad according to the invention, fig. 2 is a top view of the record pad shown in fig. 1, and fig. 3 is a side view of fig. 2, partly broken, Referring to fig. 1, 2 and 3, a record pad 1 is provided with a plurality of sheet sets 2, arranged in close juxtaposition. Each sheet set 2 is provided with a removable top copy sheet and an underlying record copy sheet 4. Instead of merely one record copy sheet 4, each sheet set 2 can have more record copy sheets 4, which are covered by one, or even more, superposed copy sheets 3. In the drawing is illustrated that three copy sheets 3 are provided adjacent each other, positioned parallel to the side edges of the record pad 1 (indicated with arrow A in fig. 2). The three copy sheets 3 are mutually secured by a line of perforation 5, such that they can easily be mutually disconnected. The record copy sheet 4 immediately below the three copy sheets 3, is common to all copy sheets 3 and has no line of perforation corresponding to the line of perforation 5 between the respective copy sheet 3. However, the record copy sheet 4 can additionally be divided in for instance three separate parts, for instance with the aid of a tear-perforation, such that there is a separate record copy sheet 4 for each of the adjacent copy sheets 3. Different from the embodiments shown and described, it is also possible, for instance to have a record copy sheet 4 common to all adjacent copy sheets 3, while the adjacent copy sheets 3 are not mutually secured, such that there is no line of perforation 5 or equivalent present between those copy sheets 3. It will be appreciated, that for all embodiments, there can be more or less adjacent copy sheets 3, for instance there can be 2, 4, 5 or more adjacent copy sheets 3. It is also possible to have a record pad with several adjacent sets of adjacent copy sheets 3, which can be mutually secured by a line of perforation, or can be mutually non-secured. Those adjacent sets can have a common or can each have an individual record copy sheet 4, which can be mutually secured by e.g. a line of perforation, if convenient. Now again referring to fig. 1-3, the upper sheet set 2 illustrated in fig. 1 and 2 have both the record copy sheet 4 and the copy sheet 3 at the respective upper edge extended with a securing edge margin 6, 7 respectively, and the securing edge margin of the respective copy sheet 3 is delimited by a line of perforation 8. The securing edge margin 7 of the record copy sheet 4 can also be delimited by a line of perforation (not shown). In said securing edge margins 6,7 respectively, there is a perforation 9, penetrated by ring elements 10 of a ring binder element, such that the superposed sheet sets 2 are assembled into the record pad 1. Instead of a ring binder element 10, the securing edge margins 6,7 can also be secured in another sense, such as with permanent adhesive, wire staples, stitching, or other mechanical binding as known in the art. Fig. 1 shows, that the lower copy sheet 3 in the drawing is already partly torn loose from the securing edge margin 6 at its left margin, and the adherence to the record copy sheet 4 therebelow is partly broken as well. The upper copy sheet 3 of each sheet set 2 is secured to the record copy sheet 4 underneath by repositional adhesive as a strip 13, which is permanently fixed to the lower side of the copy sheet 3. Each time, the strip 13 is provided along the left side edge of the respective copy sheet 3, as illustrated. Each strip 13 extends at a distance (about 2 mm.) from the tear-perforation 8 extending at the left side edge of the respective copy sheet 3 as well. According to the embodiment of fig. 1-3, the strip 13 does not extend in the securing edge margins 6, 7 respectively. In fig. 1 it is with shading schematically indicated, in which area at the record copy sheet 4, the strip of adhesive 13 of the copy sheet 3 will be adhered. It will be appreciated, that the strip of adhesive 13 itself, is permanently adhered to the side of the copy sheet 3 facing the record copy sheet 4. The term "permanently" adhered means, that the adherence of the strip of adhesive 13 to the copy sheet 3 is stronger than its adherence to the record copy sheet 4. Preferably, the adherence to the copy sheet 3 is such, that it can only be removed with the aid of chemicals. The strip 13 of adhesive is applied to the copy sheet 3 such that it is possible that the copy sheet 3, if adhered to the record copy sheet 4, can easily be detached from the record copy sheet 4 while all or substantially all adhesive of the strip 3 remains adhered to the copy sheet 3, without damaging the record copy sheet 4. If the copy sheet 3 is removed from the record pad 1, it can be adhered to the surface of e.g. a telephone or a computer-screen with the aid of the strip 13. Furthermore, each sheet set 2 is provided with means such that a message, written on the copy sheet 3, will also be copied to the one or more record copy sheets 4 therebelow. The lower side of the copy sheet 3 can e.g. be provided with a transfer material coating which, under local pressure, forms the image on the record copy sheet 4 therebelow, such as a carbon layer. It is also possible to have a separate sheet (not shown) between the copy sheet 3 and the record copy sheet 4, bearing such a carbon layer of a layer with a corresponding action. Preferably, use is made of a self contained coating which coating is applied only to the top side of the underlying record copy sheet 4, such that local imaging (blacking) of the record copy sheet 4 will appear when writing on the copy sheet 3, corresponding to the message from said copy sheet 3. The copy sheet 3 may bear printed matter appropriate to the application for which the record pad 1 is to be used. Thus, if it is intended for use as a telephone message path, the word MESSAGE may be printed on the top copy sheet 3. Furthermore, lines can be provided, parallel to the upper edge of the copy sheet 3, as indicated schematically in figure 1, 2 and 4. Similar printing may be applied to the record copy sheet 4. As is indicated in fig. 2, the arrangement of sheet sets 2, held together with the ring binder element 10, is placed on a sheet of cardboard 14, bearing a foldable flap 15, to cover or expose the arrangement of sheet sets 2. A sheet of cardboard (not shown) can be used as well. This sheet can be connected to the backing 14, e.g. along the lower or left side edge of the record pad 1. The object is to prevent copying a message, written down on the uppermost sheet set 2, to record copy sheets 4 of succeedings sheet sets 2. In the case of the embodiment according to fig. 4, but for modifications based on the embodiment of fig. 1 as well, such a protecting sheet, preferably of cardboard, intended as a writing-shield can be provided in a different manner as well.
