Abstract

A rectangular sheet bears on its rear face a pressure-sensitive adhesive and a readily peelable covering equal in size to the sheet. The covering alone is cut along lines enclosing an area having the dimensions of the desired pocket and lying directly alongside the upper edge of the sheet. This area remains secured to the sheet when the marginal portion of the covering is peeled from the sheet to expose a U-shaped adhesive region. When the sheet is secured to a flat book surface by means of the adhesive region, the area of the covering defined by the cuts remains attached to the sheet to serve as the front wall of the pocket for accommodating a library card.

INVENTOR: 44 7404? fiop/ gr-k ATTORNEYS POCKET-FORMING DEVICE FOR LIBRARY CARDS This invention relates generally to library books, and more particularly to the pockets that are applied to library books, usually on the inside of one of the covers, for accommodating library cards.

In my U.S. Pat. No. 3,372,858 a pocket-forming device is disclosed involving a sheet bearing pressure-sensitive adhesive on its rear face, and a readily peelable covering overlying it. This device has served, and continues to serve, admirably in practice; however, it has been found that in some situations a pocket-forming device of simpler construction adequately serves the purpose.

lt is therefore a general object of the present invention to provide a pocket-forming device of simple structure which can be manufactured in large quantities by a continuous lowcost procedure, and which can readily be adhesively applied to a book surface to produce the desired pocket.

Several features and advantages of the invention will be apparent from the following description in which reference is made to the accompanying drawings:

In the drawings:

FIG. 1 is a perspective view of a book provided on the inside of its rear cover with a card-holding pocket of the improved kind;

FIG. 2 is a view from the rear of a device suitable for use in forming a pocket such as that shown in FIG. 1, a part being cut away for the sake of compactness of illustration; and

FIGS. 3 and 4 are greatly enlarged fragmentary cross sections along the correspondingly numbered lines in HO. 1, the dimensions being in some respects exaggerated for the sake of clearness.

For the librarian or other user to provide a card-holding pocket on a book surface, as shown in FIG. 1, the device of FIG. 2 is made available as an article of commerce. lt consists of a substantially rectangular sheet of paper or paperboard l bearing pressure-sensitive adhesive 11 on its rear face and having a protective covering 12 of readily peelable material in overlying relation to it. Along one edge of the sheet it is advantageously folded back along a fold line 13 to-provide a marginal part which is turned in and lies beneath the corresponding marginal part of the covering 12. Within the confines of the folded-back region, i.e., at 14 (FIG. 3), the rear face of the sheet 10 is bare of adhesive. The outside of the turned-back part, however, bears a coating of adhesive as indicated at 15.

Formed in the covering sheet 12 alone are cuts which enclose an area 22 having the dimensions of the desired pocket and lying directly alongside the coincident upper edges 16 of the sheet 10 and covering 12. The cuts include two (19) which are substantially perpendicular to the upper edges 16 and extend from the upper edge 16 of the covering toward the edge 13, and a cut 20 connecting the ends of the cuts 19 and substantially aligned with the end edge ofthe turned-in margin of the from sheet 10.

Along a band or area 21 parallel to the edge 13 of the article and behind the lower margin of the area 22 there is an absence of adhesive as indicated in FIGS. 2 and 3. As a result, it may be seen, particularly in FIG. 3, that the interior of the lower end of the pocket is completely devoid of adhesive, and there is no danger therefore that the bottom edge of a library card 17 will contact adhesive.

The device as sold or furnishedto the user is easily handled, and presents no exposed adhesive. It may be manufactured in various selected sizes. When the desired pocket is to be provided, the marginal portion 18 of the rear covering 12 is simply peeled off, leaving the area 22 in place, as indicated in FIG. 2. This exposes a U-shaped pressure-sensitive adhesive region comprising the area 15, and the lateral margins of adhesive 11 alongside area 22. The covering 12 is then discarded and the front sheet 10 adhesively applied to a book surface, such as the front or inner face 23 of the rear book cover 24,

whereb the desired pocket comes immediately into bein Its rear wa l is defined by the face 23 of the book cover 24 (ilG 3) and its front wall is defined by the unremoved area 22 of the covering sheet 12. The pocket is compact, simple in nature, and well able to withstand wear and tear.

If desired, a reinforcement strip (not shown) may be interposed between the

sheets

10 and 12 in such a way that one of its longitudinal edges is coincident with the upper edges 16 of the

sheets

10 and 12. The reiiiforcement strip is preferably composed of a plastic such as Mylar, and is adhesively secured to

sheets

10 and 12.

The device described above may readily be manufactured by an economical and efficient continuous process of the type described in my above-mentioned patent.

The invention has been shown and described in preferred form only, and by way of example, and it is understood, therefore, that many variations may be made in the invention which will still be comprised within its spirit.

What I claim is:

1. A device for adhesive application to a flat book surface to form a pocket for a library card, comprising a sheet bearing on its rear face a pressure-sensitive adhesive and a readily peelable covering, said sheet and covering having coincident upper edges defining the upper edge of the pocket to be formed, said covering alone being cut along lines enclosing an area having the dimensions of the desired pocket and lying directly alongside said coincident upper edges, said area being thus adapted to remain covered when the rest of said covering is peeled away to expose adhesive, whereby said covered area can serve as the front wall of the pocket when said sheet is applied to said book surface.

2. A device as defined in claim 1 wherein the portion of said covering adjacent to said area is U-shaped, whereby a substantially U-shaped region of adhesive is exposed when said covering portion is peeled away.
