Aperture Card for Blood Typing

This card serves as a carrier for blood samples or the like and provides a machine-processible record with printed or punched indicia descriptive of or related to the samples.

In A, aperture card 1 has a rectangular area bounded by 2 abraded to a preselected depth substantially less than the card thickness. Portions of this area are then apertured out to provide a plurality of smaller rectangular openings 3 separated from each other by ribs 4 and shoulders 5 constituting the unremoved portion of the abraded area. Nonphotosensitive transparent plastic film 6 is then permanently bonded to 4 and 5 to provide, when the card is turned over, four isolated compartments. Into these, samples 7 of blood or the like can be inserted and dried. When the samples are inserted and dried, printed and punched indicia 8, 9 can be applied. Samples 7 can be applied by instrument or manually.

In B, card 10 has abraded shoulder 11 surrounding aperture 12. Nonphotosensitive transparent film 13, bonded to shoulder 11, completely overlies 12. Pressure-sensitive adhesive is applied, for example, by gravure techniques, to the outer edges of 13 on the opposite side from shoulder 11 and also at 14 in a desired cross pattern to provide a plurality of separated areas 15 and then is covered with a removable cover sheet, not shown, of glassine paper or the like. In use, the cover sheet is removed, samples are placed in areas 15, then covered over with another nonpho...
