摘要： A protector adapted to accommodate a transparency to maintain it in a clean, dust-free and dry condition so that it may be used with an overhead optical projector to cast the image carried by the transparency onto a viewing screen. The protector is constituted by an open-ended rectangular sleeve whose dimensions are appropriate to those of the transparency, the sleeve including a front panel formed of transparent, acetate film that is breathable to permit a transparency inserted in the sleeve in a wet state to dry out. Also included is a rear panel formed of a transparent, synthetic plastic film of high strength having the same length as the front panel and joined thereto at one side edge to form a folder to receive the transparency so that it is then sandwiched between the panels. The width of the rear panel is greater than that of the front panel to form a flap that is folded over to define at the other side edge of the sleeve a margin that can be provided with a set of punch holes whereby the transparency-loaded protector can be kept when not in use in a ring binder or file.

摘要： A protector adapted to accommodate a transparency inserted therein in a moist state, the transparency drying out while in the protector and being thereafter maintained in clean, dust-free and dry condition so that it is useable with an overhead optical projector which casts the image carried by the transparency onto a viewing screen. The protector is constituted by an open-ended, rectangular sleeve formed of moisture-impermeable transparent synthetic plastic film material of high strength having front and rear panels between which the inserted transparency is sandwiched, and a sheet of hygroscopic transparent acetate film which is interposed between the moist transparency and the front panel. The sheet act to absorb moisture from the transparency and to dissipate it, thereby drying out the transparency.

摘要： An album sleeve for storing and displaying at least one baseball card. The sleeve is created from a rectangular blank of transparent plastic film having three transverse fold lines whose parallel positions are such that when the blank is folded on the first line, it then defines a front panel overlying a rear panel. The second fold line is adjacent the end of the front panel to define a broad flap section which is folded over the back of the rear panel to complete the sleeve. The third fold line is adjacent the end of the rear panel to define a narrow flap section that is folded down to form an expandable internal pocket, the pocket being spaced from the second fold line to define a sleeve border that is hole punched so that the sleeve may be retained in a loose-leaf ring binder. The sleeve dimensions are such as to snugly accommodate a baseball card whose edge is received in the pocket and whose lower edge is at the fold between the front and rear panels, whereby the card is prevented from falling out of the sleeve.
