(cl.1z9`zo) 2 Claims.

This invention relates to transparent protective coverings and the like.

' One of the objects of this inventionV is the pro'- vision of a protective transparent covering which is adapted for application to printed or photographic material and whichserves to preserve same and enhance its appearance.

Another object of this invention is theprovision of filler sheets for scrap books, loose-leaf devices and the like upon which printed or pho- -tographic material may readily be mounted without requiring the use of adhesives by the user.

A further object of this inventionis the provision of filler sheets of the character above described which provide a protective transparent film for the material mounted thereon.

Other objects and advantages ywill become apparent during the course of the following description.

show the details of construction.

. Fig. 2 is a ,bottom plan view of same.

Fig. 3 -is a crosssectionalview taken ori line Fig. 4 is a fragmentary cross sectional 'view taken on line 4-4 of Fig. 1.

Referring to the drawing, andmore particularly to Figs. 1 and 2, the numeral III-designates,

generally, my improved filler sheet which comprises a sheet of transparent material I2, an in sheet I2 and completely-removed therefrom.

termediate separator sheet I3 and a reinforcing backing I4; The transparent sheet I2 is made; preferably of cellulose acetate, Celluloid, rubberized lm or any desirable transparent illm. The

said sheet is coated on one side, afs indicated rby the stippling, with a pressure sensitive adhesivevtmcn is adapted to' maintain itself in s substantially moist condition until used. I have,

foundthat an adhesive formed of synthetic resins, butyl acetate and a combination of plasticizersis well suited, for this purpose.

'Ihe separator sheet I3 comprises a kraft or ,g1assinematerial having a thermoplastic coating and'is arranged to lie contiguous to the adhesive surface of the sheet I2 to protect same until the filler sheetis to be used. A separator g sheet I3 is incompatible with the adhesive coating of the transparent sheet I2 to enable ready separation of the separator sheet I3 and'com It will be understood that, 55 portion of the transparent sheet I2 which is coplete removal thereof.

. tary finer sheet 'in which the mountedsrticles are permanently protected the function of the separator sheet is to prevent undesired adherence of the transparent sheet I2 to the backing I4, prior to use, and also te prevent the adhesive from drying. Thev separator 'that of the sheet I2.- Border lines'l, I8 and I1 are printed or drawn on\ the fblacking I4 or on the sheet I2, on one or both sides thereof, and

serve to frame the mounted material, thereby ena hancing the appearance. The backing I4 is cut on the border lines I6, along three sides, to provide a flap I8 hinged along line I9, By cutting in this fashion, the lines pf separation are rendered substantially invisible. The separator sheet I3, above described, is of lesser length than the backing I4, but is substantially of the same width and is interposed between the nap I 8 and the sheet I2, and extends 'fromthe bottom of the sheet I2 to the hinge line I9, as shown in Fig. -2. It will be seen that the border areas of the backv ing I4,voutsid'e of the lines ,I6 and I9, are adhesively secured tn the sheet I2. By this construction the separator sheet'l which is interposed between the sheet I2 and the hinged ap -I8. and incompatible with the adhesive coating on the sheet I2 can be readily separated from the Suitable holes-2li may be punched in one ofthe border areas to receive the fastening elements cf a binder, not shown. i v

When it is desired to mount something. as for' example a newspaper clipping or a picture or advertising material 'on the ller sheet, the separator sheet Il is removed, the material to be mountedl is laid down on the ap I8, preferably within the borderflines I5, and the transparent sheet is then brought. down over the said material and slight pressure is applied. It' will be seen that the mounted material, as well as those portions of the flap I8 which are not covered bythe said material, will adhere to thesheet I2.

The border area' provided on the nap will adhere" to the transparent sheet I2, thus forming a uniagainst use and exposure' and the appearancethereofsubstantlally enhanced.v r`

Because the border areas of the backing I4 are covered by the transparent sheet I2,the separator sheet I3 is adhesivelysecured only to that extensive marea. with that of the nap n. The edges of the separator sheet 4I3 are therefore left free and provide the means by which the through and protected by said sheet. a backing,

. said backing being cut to provide a hingedv flap said sheet may be grasped whenseparationlof the sheets is desired.

It should be noted that the mounted articles are Ladhesively secured to the transparent sheet I2 and not to the backing i4. Should it -be desired to remove a particular article from the ller sheet, the article maybe cut out without damage to itself, by cutting along the edges thereof, the said article, as it is removed, having a protective transparent film permanently secured to its surface.

From the foregoing, it is thus seen that I have provided new and novel means for preserving and protecting articles of the character described and for enhancing the appearance thereof.

It is to .be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention and a border area around all sides thereof, said nlm-like sheet permanently adhering to said backing along the border area, a separator sheet interposed between said nlm-like sheet and said hinged fiap and being incompatible with the adhesive' coating to enable ready separation and complete removal of said separator sheet from said nlm-like sheet to permit the article to be permanently adhered to said iilm-ike sheet between said sheet and said hinged ap and said film-like sheet being permanently adherable to said hinged ap.

2. A sheet for the display of articles comprising a flexible, film-like sheet of material provided with a transparent-pressure sensitive adhesive coating on one side thereof, saidv pressure sensitive coating enabling articles which are to be displayed to be adherently afiixed to and bonded with said coating, said sheet being transl parent so that articles so afilxed will be visible through and protected by said sheet, a border member to` which' the outer'portions of the lmlike lsheet is permanently secured, a backing ap, -a separator sheet interposed Ibetween said film-like sheet and the backing ap and being incompatible with the adhesive coating to enable ready separation and complete removal of said separator sheet from the film-like sheet to permit the article to be permanently adhered to said lm-like sheet between said sheet and said flap and said film-like sheet being permanently adherable to said backing flap.
