9 Claims, 5 Drawing Figures A LIGHT-TIGHT CARTRIDGE FOR CONTAINING SHEET MATERIAL BACKGROUND OF THE INVENTION Many cartridges have been designed for shipping and storing sheet material such as aperture cards formed with an aperture having a section of light-sensitive film mounted therein which are openable when desired to themselves, but when opened are not resealable so that removal of a partially empty cartridge would expose some or all of the contents to light.

SUMMARY OI THE INVENTION The present invention is thus directed to a cartridge for packaging and storing sheet material bearing a light-sensitive film portion, such as aperture cards, and, more particularly, one which also permits the material to be dispensed therefrom by feeding means associated with photographic apparatus.

. A cartridge embodying the novel features of the present invention is advantageous in that it permits the sheet material to be supplied to the photographic machine without removing the sheet material from the cartridge. This permits the loading of a photographic machine with a supply of light-sensitive material in a lighted area and eliminates the possibility of exposure of some of the material to stray light and physical damage to said material, as may be the case when it is necessary to remove the material from the cartridge and place the same in amachine when -themachine is in a. darkroom. I

This invention is also advantageous inthat it provides a reclosable hermetic cartridge which is moistureand light tight before it is opened for use and after reclosure should it be necessary to remove a partially used cartridge from the photographic apparatus.

The present invention is particularly adapted for use with cards of the type commonly employed in tabulating and storing systems which have an aperture formed therein and sorting a film section of light-sensitive material mounted in the aperture. The cartridge is adapted for use with apparatus of the type described in the commonly assigned, copending U.S. application, Ser. No. 304,446, entitled Card Loading Mechanism for a Photographic Copying Machine and filed on even date herewith in the names of Endter et al. In this arrangement, the aperture cards containing unexposed film are introduced'into the apparatus contained within a hermetic cartridge which is automatically opened and the cards'liftedout of the cartridge for use. The cartridge is so arranged that it can only be inserted into theapparatus in the proper orientation. Moreover, should it be necessary, the unused cards may be returned to the cartridge, the cartridge again be hermetically sealed, and

portion which has outside dimensions generally equal -a generally rectangular cross section, a bottom wall portion, and opposed side and end walls connected to the bottom wall portion. The body portion has an open top and an opening in the bottom wall portion. A removable top is provided for the open top of the body portion and a closure member is provided for the opening in the bottom wall portion. The closure member comprises a support plate disposed within the body to the outside dimensions of the sheet material. The closure member is arranged to engage the periphery of the opening in the bottom wall portion and has means engageable exterior of the cartridge for movement of the closure member into and out of engagement with the periphery of the opening.

More specifically, the present invention provides a molded plastic light-tight hermetic cartridge for containing a plurality of sheet members bearing a lightsensitive element, e.g. aperture cards, from which the sheet members may be withdrawn. The cartridge comprises a molded body portion having a generally rectangular cross section, a bottom wall portion, and opposed side and end walls connected to the bottom wallportion. The body portion has an open top and an opening in the bottom wall portion. The side walls and one of the ends walls extend beyond the bottom wall portion to form a skirt member on three sides of the cartridge.

Wall means is provided, coextensive with at least twosides of the opening in the bottom'wall portion, which extends outwardly from the bottom wall portion. This I coextensive wall means has a flange portion at the outer edge thereof substantially parallel to the bottom wall portion and extending partially over said opening removable top is also provided for the body portion which has peripheral seal means arranged to positively and releasably engage the upper edge of the body portion. The removable top has a rib member spaced inwardly from said seal means which is arranged not to contact the topmost sheetmember when the top is in engagement with the body portion. A closure member is provided for the opening in. the bottom wall portion and comprises a support plate disposed within the body portion. The support plate has outside dimensions generally equal to the outside dimensions of the sheet members with means on the outer surface of the closure member arranged to positively and releasably engage the inwardly extending seal means about the opening in the bottom wall portion. The closure member also has longitudinally extending channel means extending outwardly therefrom and arranged to extend 5 through the opening in said bottom wall portionfor engagement exterior of the cartridge for movement of the closure member into and out of engagement with the opening and to lift the sheet material out of the top of the opened cartridge. I

The various features of novelty which characterize the present invention are pointed out with particularity 3 in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and the specific objects obtained by its use, reference should be had to the accompanying drawings and descriptive matter in which a preferred embodiment of thev present invention is illustrated and described.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top perspective view of a closed cartridge incorporating a preferred embodiment of the present invention;

FIG. 2 is a bottom illustrated in FIG. 1; FIG. 3 is an exploded perspective view, partially in section of the cartridge illustrated in FIG. 1;

FIG. 4 is a sectional view of the cartridge taken along line 4-4 of FIG. 1; and

FIG. 5 is a sectional view of the cartridge taken along line'5-5 of FIG. 1.

The cartridge of the present invention comprises three pieces, a body portion 12, a removable top or cover l4, and a bottom closure member 16, all preferably molded of a moisture-proof material such as polythylene to provide the desirable hermetic properties to the assembled cartridge. 8

The body portion 12 is generally rectangular in cross perspective view of the cartridge section, slightly larger than the aperture cards to be contained therein, and comprises opposed side and end walls, 18 and 20 respectively, and a bottom wall portion 22. The bodyportion has a substantially completely open top and the bottom wall portion 22 is provided with a centrally disposed opening 24 which permits a portion of the above referenced photographic apparatus to enter the cartridge and engage the bottom closure member 16 in a manner to be described more thoroughly hereinbelow. The upper edge of the side and end walls, which form the periphery of the top opening,are provided with a continuous, inwardly extending peripheral rib 26. The side and end walls provided with inwardly extending reinforcing bosses 27 which supply the necessary rigidity to the cartridge walls. The bosses also provide the aperture cards with the requisite guidance without excessive contact therewith. Furthermore, the space within the cartridge. adjacent the bosses facilitate the cartridge loading by handling means including a plurality of fingers that reach down in the cartridge.

The cover 14 is substantially planar and is provided with a downwardly extending peripheral lip 28 which has an outwardly extending flange 30 at its outer extremity. The inner periphery of lip 28 closely engages the outer surface of the upper edge of the body portion 12. The cover is provided with a second downwardly extending peripheral lip 32 which is spaced inward from lip 28 a distance substantially equal to the thickness of the rib 26 on the periphery of the top opening of the body portion 12. The two lips 28 and 32 are arranged, when the cover is on the body portion. to engage the rib 26 around the top opening and to form a moisture and light seal which can be readily opened or reclosed. The cover 14 is also provided with a downwardly extending flange 34, spaced inwardly of lip 32. Flange 34 is .longer than lips 28 and 32 but is arranged not to contact the uppermost of the aperture cards 36 (FIG. 3) of a full cartridge.

The bottom wall portion 22 of the cartridge body is provided with a centrally disposed, elongated opening 24 and has an inwardly extending peripheral wall means or rim 38 which terminates within the cartridge in an enlarged bead 39 similar to the rib 26 at the top opening. This portion of rim 38 completely surrounds the opening 24. The rim 38 extends outwardly below the bottom wall portion on at least the two longitudinal sides of the opening 24 and is provided along these sides with a flange 40 extending parallel to the bottom wall portion over the opening therein. The portion of the rim 38 which extends below the bottom wall portion, may or may not extend around one end of the opening, as at 42, but the other end of the opening does not have such a rim portion.

The lowermost portions of the opposed sidewalls l8 and one end wall 20 adjacent the end portion 42 of rim 38 extend beyond the bottom wall portion 22 a distance substantially equal to that of the rim 38. A plurality of reinforcing members 44 extend between the rim 38 and the extended portion of the side and end walls to provide rigidity to the bottom of the cartridge.

The bottom closure member 16 comprises a support plate 46 which has a size generally equal to the size of the sheet members to be held in the container. The bottom closure member is arranged for vertical movement in the cartridge body portion 12 and is provided with a pair of spaced flanges 48 on the bottom thereof which extend parallel to the periphery of the plate member. These flanges are arranged, when the closure member is in the bottom of the body portion, to sealingly engage the bead 39 on the upper end of rim 38 to form a moisture and light seal for the opening 24 in the bottom wall portion which can be readily opened and reclosed. A central portion of the support plate is recessed, as at 50, to strengthen the bottom closure member and form a support which extends outwardly through the opening 24. A pair of longitudinal ribs 52 extend outwardly from the outer portion of recess and form a gripping surface by which the previously referenced apparatus can positively grip the closure member I6 for vertical movement in the cartridge. The support plate is also recessed, as at 54, at opposite ends beneath the area of the aperture card containing the photographic film to prevent damage of the film by contact with the support plate. There are two such recesses 54 so that the closure member is longitudinally symetrical to avoid the necessity or orienting the closure member during assembly. The support plate is also provided with recesses 56 and 58 along the edges, also symetrically arranged, for detecting and feeding the aperture cards in the photographic apparatus.

When the cartridge is filled with aperture cards and the top cover 14 and the bottom closure member 16 are in place, with the respective flanges engaging the respective beads on the body portion, a hermetic, lighttight container is provided which requires no additional wrapping to protect the contents. Moreover, since both openings are resealable, the cartridge can be partially emptied and then resealed providing further protection to the remaining contents. Further, the present cartridge is arranged for cooperation with apparatus such that the cartridge provides hermetic and light protection until after it is inserted into the apparatus. After the cartridge is inserted into the apparatus in the closed condition, and in only one orientation because of the omission of the rim 38 from one end of the opening and tions can be effected within the the omission of the corresponding end wall extension, the flanges 40 are engaged by a relatively stationary element to prevent vertical movement of the cartridge. The apparatus is then closed and the cartridge is in a dark compartment. Thereafter the flange 30 of the top cover is engaged and the cover is lifted off. During insertion, the dependent ribs 52 have been engaged by a movable element of the apparatus which is arranged to lift the lower closure member and the cards thereon, and to lift the cards into contact with a feeding device for transport to an exposure station. Because of the fact that the ribs are positively engaged, it is also possible for the apparatus to lower the cards back into the cartridge and to pull the bottom closure member into sealing engagement with the sealing means about the opening in the bottom all portion. Likewise, the top can be reattached and the rescaled cartridge may be safely removed from the apparatus.

Accordingly, it will be seen that the present invention provides a hermetic, light-tight cartridge for sheet ma-,

terial bearing a light sensitive element, such as aperture cards, which both protects the elements and permits their automatic handling in the appropriate apparatus.

The invention has been described in detail with particular reference to preferred embodiments thereof, but it will be understood that variations and modificaspirit andscope of the invention.
