Record pad

Abstract: A record pad (1) comprising a plurality of sheet sets (2) each 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 adjacent an edge of the record copy sheet and in which one edge of record copy sheet (4) extends beyond the edge of the top copy sheet to provide a margin (5) which margin (5) serves to be secured to other margin (5) of the pad for record purposes.

Description: This invention has reference to record pads having repositionable adhesive on the back of each sheet in the pad. In recent years pads of paper have become very popular in which each sheet has a marginal stub area bearing on its underside a band of non-drying, slightly-tacky adhesive which, while permanently bonded to the underside of the sheet, only temporarily bonds to other surfaces, including to the stub areas of the top surfaces of respectively adjacent like sheets in the stack which constitutes the pad. The general concept of such a product is disclosed in the Swiss Patent of Eugster 452,479 dated 31 May 1968. Eugster discloses a paper pad that is composed of self-adhesive individual sheets and is characterised in that each sheet is detachably joined to the sheet underneath it by means of a non-drying adhesive and in that the strip of adhesive provided at the edge of each individual sheet has one side which is smooth and adherent but does not take up adhesive while the other side carries the adhesive. The side carrying the adhesive may be arranged on the underside of the sheet. The adhesive applied to this side cannot be removed without chemical agents. When two such surfaces of adhesive strip which have been glued together are separated, virutally all the adhesive is left on the underside while the upper surface remains unwetted. When assembling such a 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 so that the sheet which has been removed can be fixed by light finger pressure to another surface without the use of fresh adhesive. Adhesives and paper useful in making such products are well known in the particular art. It is also known to provide multiple sheet forms with carbonless coating for producing multiple copies of an orignial writing and reference may be made by way example to US Patent Specification Nos 3981523, 4126334 and 4199174. Also European Patent Application No 88301727.9 describes a pad having a plurality of sheets arranged in a stack with transfer material positioned between each of the plurality of sheets and with a repositionable adhesive strip positioned at the head of each sheet to secure it to the adjacent sheet. Also British Patent Specification no 2214131 describes a pad 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. It is an object of the present invention to provide an improved record pad. It is another object of the present invention to provide an improved record pad made up of a plurality of sets of sheets in which a message or other data may be applied to the top sheet of the set and a copy of the message or other data made on the underlying sheet and in which one sheet of the set may be detached leaving a copy or the remaining record copy sheet. According to the present invention a record pad comprises a plurality of sheet sets, each set comprising at least a removable top copy sheet and an underlying record copy sheet in which the top copy sheet lies in close juxtaposition on the underlying record copy sheet and bears a strip of repositionable adhesive adjacent an edge of the record copy sheet and in which the record copy sheet extends beyond the edge of the top copy sheet to provide a margin which margin serves to be secured to other margins of the pad for record purposes. Embodiments of a record pad in accordance with the present invention will now be desribed by way of example with reference to the accompanying drawings wherein: Fig 1 is a perspective view of a record pad in accordance with the invention, Fig 2 is a sectional view along the line 11-11 of Fig 1, Fig 3 is a perspective view of a single set, Fig 4 is a sectional view similar to Fig 2 of a modification, and Fig 5 is a view showing the pad of Fig 1 in use Fig 6 shows a further modification. Fig 7 shows a record pad associated with a cover. Referring to Figs 1, 2 and 3 a record pad 1 comprises a plurality of sheet sets 2 arranged in close juxtaposition. Each sheet set comprises a removable top copy sheet 3 and an underlying record copy sheet 4. The relative arrangement of removable top copy sheet and underlying record copy sheet is best shown in Fig 3 although in practice it is not intended that the record pad will comprise a single set. The underlying record copy sheet 4 which bears no tear off perforations extends beyond the edge of the top copy sheet 3 to provide a margin 5 which margin serves as a means to secure the underlying record copy sheet together by means (not shown). Such securing means may comprise a strip of adhesive along the margin 5 of each record copy sheet 4 between adjacent record copy sheets 4, or it may comprise adhesive positioned along the outer edge of each record copy sheet 4. Other means such as wire staples, stitching, paper staples or mechanical binding as known in the art may be used to secure the record copy sheets together. Each top copy sheet 3 is secured to the record copy sheet underlying it by repositionable adhesive arranged in the form of a strip of such repositionable adhesive 6 adjacent the edge of the top copy sheet 3 adjacent the margin 5 and parallel to the edge of the top copy sheet 3. This repositionable adhesive 6 is arranged in such fashion that the top record copy sheet 3 is detachably joined to the underlying record copy sheet so that the sheet 3 may be removed from the underlying record copy sheet 4 and applied to another surface. Also between each top copy sheet 3 and the complementary underlying record copy sheet 4 a transfer material coating 7, 8 (see Fig 3) is provided to enable a message or other data applied to the top copy sheet 3 to be copied on to the underlying record copy sheet 4. Such transfer material coating may be of the kind sold under one of the Trade Marks MCP, Idem or Action and may be of the kind in which, as shown in Fig 3, a donor coating 7 is applied to the underside of the top copy sheet 3 and an acceptor coating 8 is applied to the top side of the underlying record copy sheet 4, or preferably may be of the kind referred to as a self contained coating which coating is applied only to the top side of the underlying record copy sheet 4 or may be of the kind in which the image forming materials are incorporated into the paper when it is manufactured. It is preferred that the self contained coating be employed so that the adhesive can be applied to the lower uncoated side of each sheet. The top copy sheet may bear printed matter appropriate to the application for which the pad is to be used. Thus if it is intended for use as a telephone message pad the word Message may be printed on the top copy sheet 3 as shown at 12 in Figure 1. Similar printing may be applied to the record copy sheet 4 as may be appropriate but such sheet 4 may bear corresponding printing. Preferably a sheet of cardboard 9 (see Fig 5) may be associated with the pad so that the sheet 9 may be inserted between the uppermost sheet set 2 of the pad and the next succeding set 2 of the pad to provide a writing shield. This is intended to prevent a message or data applied to the top set being duplicated on the underlying record copy sheet 4 of the record copy sheets of succeeding sets. Also the pad may be provided with a cover sheet associated with the sheet 9. Thus a cover may include a backing sheet to lie beneath the lowermost set of the pad with one fold over part serving as a writing shield sheet and another fold over part to serve as a cover sheet and with the pad temporarily removed within the cover. In use the pad 1 may be used as a telephone message pad. The pad is positioned on a firm surface and the sheet of cardboard 9 is inserted between the uppermost set 2 of the pad and the succeeding set 2 and a message is written on the removable top copy sheet 3. The message written on the sheet 3 is duplicated by the transfer material 7, 8 on the underlying record copy sheet 4. The removable top copy sheet 3 is then removed and placed in a position for the intended message recipient to read it and the copy sheet 4 remains secured to the other sheets of the pad as a record. It is preferably placed on a firm surface by the repositionable adhesive where it will remain until the message recipient deals with it and removes it. Various modifications to the construction of the pad 1 may be made. Thus as shown in Fig 4 an additional copy sheet may be inserted in such set underneath and in register with sheet 4 as the last sheet 10 of the set. A transverse line of perforations 11 is provided in the sheet 10 to enable the body of the sheet 10 to be removed. This line of perforations 11 is provided adjacent the head of the sheet 10 preferably in line with and underlying the edge of the top copy sheet 3. Such a pad may be suitable for use for example in a take away restaurant in which information about a take away meal is applied to the top copy sheet 3. Such sheet is removed and applied to the container containing the take away meal and the detached copy sheet 10 may serve for example as a receipt for payment of the meal or sent to the kitchen of the take away restaurant as an instruction to prepare the meal. The record copy sheet 4 remains in the pad as a record. If desired the pad may comprise a series of record pads arranged side by side as shown in Fig 6. The record pad comprises a "three to view" top copy sheets 3 with a "three to view" underlying record copy sheets 4 with strips of repositionable adhesive 6 between the top copy sheets 3 and the underlying record sheets 4 and transfer material 7, 8 (not shown) between the sheets 3 and 4. The underlying record copy sheets 4 extend beyond the top copy sheets 3 to form a margin 5 to provide a means for securing the record copy sheets together.
