20997~
so that the flap can be folded over ancl adhered to the back me~ber to protect the repositionable adhesive coating and reduce the overall dimensions o~ the device when the device is being stored.
The device of the present invention is particularly useful for displaying recipe cards and photographs. The presence of the repositionable adhesive permits the device to be adhered to a surface such as a refrigerator, and thereafter be repositioned 10 thereon or removed therefrom without marring the surface or leaving significant adhesive residue on the surface. In the event the back member of the sleeve is also transparent, presence of the repositionable adhesive coating on the flap permits convenient access 15 to both sides of the article without removing the device from the substrate to which it has been adhered.
Moreover, the design of the device of the present invention conveniently permits the flap or flaps to be folded over and adhered to the sleeve of 20 the device to reduce the dimensions of the device and protect the repositionable adhesive coating from soiling or the like. This feature is particularly convenient when the article held in the sleeve is a recipe card which may then be stored, without removing 25 it from the device, in a box of dimensions tailored to the dimensions of the recipe card.
A particularly preferred device of the present invention is characterized by the flap being joined to the top edge of the sleeve. The front member 30 and back member are joined along that top edge, but form openings along both of the side edges of the sleeve to permit an article to be conveniently inserted into or removed from the sleeve.

As shown in Fi~. 3, hinge 3 6 permits flap 26 to be folded over sleeve 12 and adhered by means of the repositionable adhesive coating of tape 32 to back surface 34 of back member 14. It is contemplated that 25 hinge 36 and flap 26 may be made of the same material.
Front member 16 may comprise essentially any transparent film. Generally the film will be about 0.5 mil (0.012 mm) to 8 mils (0.2 mm) in thickness, and will preferably be about 1 mil (0.025 mm) to about 4 30 mils (0.1 mm) in thickness. Preferred films are biaxially oriented polypropylenes and biaxially oriented polyesters. The most preferred film is the low haze, 1.6 mil, biaxially oriented polypropylene film available under the trade designation 35 Scotchpar~KF30~FO from 3M Company of St. Paul, MN.
Back member 14 may comprise, for example, a transparent film, a colored (translucent) film or 20~7~
paper. The preferred back member 14 comprises a transparent film such as one of the films discussed above in the context of front member 16. The back (outer) surface of back member 14 may, if desired, be 5 coated with a release coating (not illustrated) to facilitate removal of flap 26 therefrom after flap 26 has been adhered to back member 14 as illustrated in Fig. 3.
Flap 26 may comprise, for example, 10 polypropylene, polyester or paper. The preferred material for flap 26 is the 3.2 mil (0.081 mm), biaxially oriented polypropylene film available under the trade designation Kimdura~ Synthetic Paper from Kimberly-Clark Corporation of Munising, MI.
The repositionable adhesive coating on tape 32 may be any conventional repositionable adhesive which permits device 10 to be adhered to and removed from a variety of substrates multiple times without significant loss of adhesive capability. Examples of 20 repositionable adhesives which may be used include the tacky, solid microsphere adhesives disclosed in U.S.
Patent Nos. 3,691,140 and 4,166,152. Other suitable ~; repositionable adhesives include those comprising non-tacky microspheres such as the adhesives disclosed in 25 U.S. Patent No. 4,735,837. Still other suitable repositionable adhesives comprise tacky, hollow microsphere adhesives such as the adhesives disclosed in U.S. Patent No. 5,045,569.
The preferred repositionable adhesive '!
30 comprises tacky, solid microspheres of a type disclosed in said U.S. Patent Nos. 3,691,140 and 4,166,152, and a ; non-spherical acrylate copolymer of the type disclosed in U.S. Patent No. Re. 24,906. The most preferred repositionable adhesive comprises a 90:10 ratio by 35 weight of a m:ixture of said solid microspheres and a non-spherical 95.5:4.5 isooctyl acrylate:acrylic acid pressure-sens:itive adhesive polymer.
