Int. Cl. G09f 1/00 U.S. Cl. 40-159 10 Claims ABSTRACT F THE DISCLOSURE An aperture card has transparent films affixed to each side of the card about the periphery of the aperture. At one end of the aperture the film is longer and afiixed to the card farther away from the aperture than is the film at the opposite side of the card. At the same end and between the lines of afiixation of the films is a slit through the card to give Iaccess to the aperture for the insertion of a microfilm or the like.

BACKGROUND OF THE INVENTION The conventional procedure for providing access to the interior of an aperture card is to have one edge of one of the films covering the aperture either unafiixed to the card or affixed with a resealable adhesive. This, of course, permits the film to be removed away from the card along that one' edge so that a microfilm, picture or other object of a similar nature may be inserted into the aperture or removed therefrom, if desired. The problem that arises is that the film along that one edge is not as secure as the remaining parts of the film. This often results in the film at that one edge being caught by another card, some of the mechanical equipment with which the cards are used, etc., and the film is torn or at least loosened. This will then permit the escape of the object from the aperture with the danger of it being lost or ireinserted in the wrong card. Even when the film has not been so damaged, the fact that it is not securely affixed to the card about all of its edges, may Ipermit a similar escape of the object from the aperture.

The present invention is to remedy this defect or problem that has arisen in connection with the use of conventional aperture cards and to more securely hold the object in the aperture after it has Abeen inserted therein. At the same time, ready access is provided to the interior of the aperture when desired. As will be hereinafter apparent, this is accomplished by putting the access opening to the aperture in the aperture card per se. This access opening is in the form of a slit in the card lwith the films being arranged i so that the slit at one side of the card is exposed for initial entry and the slit at the opposite side of the card leads into the aperture.

Furher objects and advantages Will become apparent from the following description taken in conjunction with the drawings.

SUMMARY OF THE INVENTION The invention relates to an aperture card having an access opening provided by a slit through the card with the slit at one side being exposed and the slit at the opposite side communicating with the aperture in the card.

DESCRIPTION OF THE SPECIFIC EMBODIMENTS Although the following disclosure offered for public dissemination is detailed to ensure adequacy and aid understanding, this is not intended to prejudice that purpose of a patent which is to cover each new inventive concept therein no matter how others may later disguise it` by variations in form or additions or further improvements.

The claims at the endhereof are intended as the chief aid p toward this purpose; as it is these that meet the requirement of pointing out the parts, improvements, or combinations in which the inventive concepts are found.

FIGURES 1 4 illustrate a cardgenerally 11 having two` faces 12 and 13, with an aperture 14 extending therebe` tween. At face 12 the aperture 14 is covered by a film 16,

while at face 13 the aperture is covered by a film 17. It Will be noted that at one end of the aperture the film 17 is longer than is the film 16. Thus at that end of the aperture there is a first portion 18 of the card over which the film 16 (as Well as 17) lies, and a second portion 19 of the card over which only the film 17 lies. Film 16 is afiixed to the Icard along an area inside of and extending entirely around the periphery of the film by a suitable adhesive 21. Similarly, entirely around, but inside, the periphery of film 17 is a band of adhesive 22 securing film 17 to the card.

Between portions 18 and 19 of the card is an access slit 23. Thus by raising the portion 18 of the card at the slit 23, as illustrated in FIGURE 4, there Iwill be an opening extending from the exterior of the card at face 12, between portion 18 and film 17, and into the internal opening defined by aperture 14 in the card. An object such as a strip of microfilm 24 may be inserted through this access opening into the aperture. When the object has been inserted and the force employed to raise portion 18 of the card is removed, the portion 18 will return to the position illustrated in FIGURE 3 securely trapping the object 24 in the aperture.

Films 16 and 17 are merely thin, transparent plastic films. The stock from which cards 11 are conventionally made is normally heavier and more rigid than is the stock from which films 16 and 17 are formed. Because of this, the card is more likely to remain fiat at slit 23, and there is considerably less likelihood, with this construction, of unintentionally having the access opening to the interior of the pocket coming apart with the result that the object in the aperture will unintentionally fall out of the aperture. As a further precaution against any such undesirable occurrence, several dots 0f pressure sensitive, resealable, adhesive may be placed between portion 18 of the card and the adjacent part of film 17. Two such dots of adhesive are illustrated at 25 in FIGURE 2. The adhesive can be such as those made of polyvinyl acetate.

FIGURES 5 and 6 illustrate an alternative embodiment which corresponds to FIGURES l-4, except for the configuration of the access slit. Thus, corresponding numbers have been applied to the corresponding parts. In the embodiment of FIGURES 5 and 6, the slot is discontinuous. It is formed by three smaller slots 27, 28 and 29. These are aligned with each other and separated by uncut or unsevered portions 30 of card 11. When it is desired to insert an object 214 into aperture 14, it is only necessary to pull up with a slight force on portion 18 of the card so as to tear the card at uncut portions 30 between the slots 27-29.

FIGURES 5-7 also illustrate a tool which may be advantageously employed to facilitate inserting objects 24 into aperture 14. This tool comprises a suitable handle, not shown, to which is affixed a fiat blade 32. Blade 32 has a nose 33 at its distal end, with the distal end of the nose being tapered in thickness, as best seen in FIGURE 6. Rearwardly of the distal end of the blade are a pair of side guides 34 to hold the microfilm 24, while permitting the microfilm to slide therethrough longitudinally of the blade. The distal end of the nose 33 can be inserted in center slot 28 and by forcing the nose on into the slot, the uncut portions 30 will be severed. Thereafter the blade is moved approximately to the position illustrated in FIGURE 6, where it serves to hold the portion 18 of the card out of the way for easy access into aperture 14. From the FIGURE 6 position the microfilm 24 is slid to the left and into aperture 14. With the microfilm in the aperture, the blade 32 is withdrawn.

FIGURES 8 and 9 again illustrate an emb-odiment substantially corresponding to the embodiment of FIGURES l-4, except for the configuration of the access slot. In this embodiment the slot 36 is curved with the ends of the slot being closer to aperture 14 than is the center of the slot. The advantage of such a curved slot is illustrated in FIG- URE 9. With the card 11 held in the hands, the card is bent so that the right end turns downwardly with respect to the left end, as illustrated in FIGURE 9. When this is done, the slot 36 automatically opens to provide an access opening 37 leading to the interior of the aperture 14. With the opening 37 present, it is a simple matter to slide a microfilm or other object through this opening and on into aperture 14.

FIGURE illustrates an alternative embodiment wherein the card generally 40 has five apertures 41-45. Covering these apertures on one side is a film 46 (corresponding to film 16), and on the opposite side is a film 47 (corresponding to film 17). Slits 48-52 are provided for each of the apertures 41-45 respectively. The slits 48-52 are not connected. The construction otherwise corresponds to that illustrated in FIGURES l-4. The slits 48-52 are exposed on one side of the card (the upper side, as illustrated in FIGURE 10), and at the opposite side of the card provide access to the apertures 41-45. Apertures 41- 45 can be used, for example, to hold 5 strips of 8 mm. film. If desired, for example, only two apertures could be provided to hold two strips of 16 mm. film within substantially the same space on a card.. With the multiple aperture card as in FIGURE 10, a single slit (slits 48-52 connected) could be employed to provide access to all of the apertures.
