11 Claims.

This invention relates to packs or containers for loose sheets and more particularly to a sheet pick-up to facilitate the removal of the uppermost sheet upon opening the cover of the pack.

The difliculty. in removing a single sheet of carbon paper, for example, from its container is well known. The sheets, being made of a thin tissue paper, are prone to adhere slightly to one another and hence it is difll'cult to remove one sheet alone without wrinkling or tearing it, defacing it in some .manner or displacing other sheets in the pack. In addition to the difllculty arising from the fine texture of the paper itself, thecarbon rubs off the sheet and soils the hands of the person removing it, and hence a task which ought to be a simple one becomes rather difficult and distasteful.

It is an object of my invention to overcome the aforementioned difliculties and make the task of removing a single sheet of paper from its pack a simple one.

Another object of my invention is to provide an improved pick-up member which is attached to the cover of the sheet container so that the mere raising of the cover will lift the uppermost sheet where it may be grasped easily.-

A further object is to provide an improved pickup member for a carbon sheet container to which the uppermost sheet in the pack will adhere when a slight pressure is applied to said pick-up member.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following specification and particularly pointed out in 'the appended claims.

In Figs. 1-5 I have illustrated a construction em bodying my invention applied to a common form of carbon sheet pack employed for holding a relatively small number of carbon sheets. This carbon pack comprises a plurality of carbon sheets loosely disposed in a container or folder 2 I, said folder including an upper or cover leaf 22 and a lower or back leaf 23 hinged to the cover leaf 22 as at 24. In the cover leaf 22, preferably in the lower right-hand'portion as viewed in Fig. l and near an edge thereof, is a cut or aperture 25 over which is mounted a disk or member 26 made of paper, thin celluloid, or any other suitable resilient material. Whatever size or shape the aperture 25 may assume, for example, a circular out which could be approximately one-half inch in diameter, the resilient member 26 may be the same or any suitable shape, but it should be of such dimensions as will allow it to completely fill, cover, extend across or underlie the aperture 25 and preferably overlap the edges thereof as shown in Figs. 2, 3, 4 and 7 to 10 inclusive.

On the underside of the disk 26 there is supplied a suitablepick-up means which may be in the form of a coating, film or layer of a pressuresensitive, non-drying adhesive material as indicated at 21, said adhesive causing the disk to adhere to the surface of the cover in close proxmity with the aperture 25. The adhesive used in this connection is of such a character as to permit of many applications without losing its tacky surface, such as described in Patent No. 1,760,820 or Re. 17,760. This construction of the disk with its pressure-sensitive adhesive mounted over the aperture embodies one form of my invention, and comprises what may be termeda I prefer to inscribe the word Press or some such indication on the upper non-coated side of the disk 26.

In addition to this construction of the adhesive coated disk member, it may be made by only applying the pressure-sensitive non-drying adhesive over that portion of the disk which registers with the aperture. Then the disk or resilient member could be applied to' the cover 22 by any suitable means suchas a drying adhesive applied over those-portions of the disk which came in contact with the cover. It will be observed 5 that in the form of the invention shown in Figs. l-5 the adhesive coating 21 is not normally in contact with the uppermost carbon sheet (Fig. 2) and does not touch said sheet until pressure is applied to the disk 26, to flex said disk through the aperture 25 as shown in Fig. 3. Thus, it will be apparent that the aperture 26 constitutes in effect a finger receiving aperture. f

In operation, when it'is desired to remove one of the carbon sheets 20 from the folder 2|, illustrated in Figs. 1 to 5 inclusive, the operator applies a slight pressure to the disk 26, as by means of her index finger, as shown in Fig. 3. Previous to the application of pressure the parts occupy the relationship shown in Fig. 2, but when the index finger is applied to the disk 26, its resilience will allow it to be depressed (Fig. 3) through the finger receiving aperture 25, causing the pressure-sensitive non-drying adhesive 21, to come in contact with the uppermost carbon sheet 20. Only a slight pressure need be applied and the slight contact of the adhesive with the carbon sheet will make it adhere to the disk. The finger may then be removed and the cover raised, said cover now carrying along with it the lower right-hand corner portion of the uppermost sheet of carbon paper, as illustrated in Fig. 4. The cover is then lifted to a convenient height where the carbon sheet 20 can be grasped by the operator and removed with ease.

In the above described form of theinvention, or in the form to be described hereinafter, the cover 22 may be equipped with a tab or lifting means 38, as illustrated in Fig. 6, to facilitate in raising the cover 22 after pressure has been applied at the point indicated by the term Press.

to bring about the adherence of the uppermost sheet to the pick-up means. If used in connection with the form of the invention shown in Figs. 1-5, an car may be provided on the disk or resilient member 26 which will accomplish the same purpose. Otherwise the tab may comprise a small folded piece'of suitable thin material which can be fastened to the cover in the proper place. In any form the tab 36 may be folded down to a position adjacent the cover leaf as indicated by the dotted line showing in Fig. 6. Such a folding action of the tab 38 will permit .several carbon packs to be stacked one upon the other in close relation. y

In Figs. 7, 8, 9 and 10 I have illustrated a construction embodying my invention applied to.

another type of carbon sheet pack which ordinarily will hold a considerably greater number of sheets than the above described folder packs. This form of pack comprises a plurality of carbon sheets 40 loosely disposed in a container 4|, said container including a flanged bottom or tray member 2 and a split top member. The split top member comprises a front cover portion 43, to be hereinafter referred to as the cover, hinged by means of a pliable strip 46 to a rear cover portion 44, said rear cover por- 70 tion 44 being permanently secured to the tray member 42.

In one of the lower corners of the cover 43 (in the upper left as viewed in Fig. 7) is a finger receiving aperture 10 of suitable size and shape,

n for example a circular opening large enough to admit a normal index finger across which is mounted a resilient supporting member or disk H secured to the cover by any suitable means, such as adhesive. The disk or member Il may be made of any thin resilient material such as rubber for example, and may assume any shape which will allow it to extend across the aperture. Preferably disk or member 'H is large enough and resilient enough to allow it to be flexed so that its under side may touch the bottom of the container. With this end in view it may be found desirable to have the disk or member H somewhat larger than the aperture and secured to the under side of the cover 43 preferably only at its extreme edges, as indicated at 13 in Figs. 9 and 10.- Such a construction will allow a maximum fiexure of the disk 1|.

On the under side of the disk or member 1| there is a pressure-sensitive pick-up means I4 which may be'a small loop of tape coated with a non-drying adhesive as shown, or it may be merely a spot of the non-drying adhesive on the under side of said member. Whatever form it takes, the means 14 is of such a character as will allow it to adhere to the uppermost carbon sheet 40 in the pack when pressure is applied through the finger receiving aperture 10 to the member ll as indicated in Fig. 9. Furthermore, it will be observed that the means 64 is normally in the position shown in Fig. 8 and not in contact with the uppermost carbon sheet. The operation of this form of my invention is directly similar to the previously described form shown in Figs. 1-5.

From the broader aspects of my invention when I refer herein to a container having a cover, this language is intended to apply to either the folder or box type of sheet pack.

From the foregoing description it will be apparent that a novel sheet pick-up means, for carbon packs, for example, has been provided which will greatly facilitate the removal of the carbon sheets from their containers.

Various changes may be made in th construction, and certain features thereof m y be employed without others, without departing from my invention as it is defined in the accompanying claims.
