SHEET 2 0F 2 ROBERT L. MA RTI N 8 QW MZZMM ATTORNEY MAILABLE DISPOSABLE VIEWER This invention relates to new and useful improvements in viewers arranged to receive transparencies or the like for viewing in enlargement, the viewer being of a type which can be disposed of after minimum usage.
A primary objective of the present invention is to provide a novel structure of viewer which is intended for disposable use after minimum usage and which in its manufacture from a blank comprises a separable part of a blank portion which before being separated comprises foldable flaps for serving as an envelope.
Another object is to provide a viewer arranged to be constructed from a blank of paper having a novel arrangement of fold lines, glue lines and cut-out portions serving to accomplish construction of the above mentioned viewer.
Another object is to provide a viewer of the type described which has face surfaces capable of carrying advertising messages.
The invention will be better understood and additional objects and advantages will become apparent from the following description taken in connection with the accompanying drawings which illustrate a preferred form of the device.

FIG. 2 is a plan view of the viewer folded with its envelope portion thereof into a mailable position;
FIG. 3 is an enlarged cross sectional view taken on the line 3-3 of FIG. 2;
FIG. 4 is an enlarged fragmentary sectional view taken on the line 4--4 of FIG. 2;
FIG. 5 is a perspective view of a viewer portion of the present invention separated from the envelope portion and folded into a viewer construction;
FIG. 6 is a cross sectional view of the viewer portion taken on the line 6-6 of FIG. 5;
FIG. 7 is a plan view of a blank from which a modified structure of viewer is constructed; and
FIG. 8 is a cross sectional view of a viewer formed from the blank of FIG. 7 with the viewer being shown in folded condition for mailing.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT One form of viewer of the present invention is constructed from a blank of paper 10, FIG. 1. This blank comprises in general three main longitudinal panels 12, 14 and 16. Panels 12 and 14 are connected by a fold line 18 and panels 14 and 16 are connected by a perforated line 20 which as will be seen hereinafter serves as a fold line for holding the panel 16 into a compact unit with the other panels for mailing and also as a tear line to remove the panel 16 when desired. Panel 12 has a narrow panel 22 connected longitudinally along its outer edge by a fold line 24 and this panel has a glue surface 26 thereon.
Panel 14 has end tabs 28 connected thereto by fold lines 30. 7
Panel 16 comprises the viewer portion and has five sections 32, 34, 38 and 40. Sections 32 and 34 are connected by a fold line 42, sections 34 and 36 are connected by a fold line 44, sections 36 and 38 are connected by a fold line 46, and sections 38 and 40 are connected by a fold line 48. Sections 34 has an aperture 50 therein for supporting a lens 52, and section 38 has a viewing aperture 54, which as will be seen hereinafter comprises a viewing aperture for a slide 56, FIG. 6, to be viewed through the lens 53 when the viewer is folded. Section 38 has a pair of tabs 58 cut therein on opposite sides of the aperture 54 for removably supporting a slide 56 on the viewer, FIG. 6, as will be more apparent hereinafter. For purposes of assembly, the lens has a peripheral groove 53 and has snap-in engagement in aperture 50.
Panel 16 is shorter at one end than the panel 14, and extending from such shorter end of the panel 16 is a tab 60. The opposite end of the panel 16, namely, the section 40 thereof, has a U-shaped cut line 62 arranged to receive the tab 60 in a folded position of panel 16, hereinafter described in greater detail. Such panel when separated from the rest of the blank can be formed into the viewer shown in FIGS. 5 and 6. However, before its separation the other panel sections are arranged to serve as an envelope for mailing the viewer. For this latter purpose, and with reference to FIGS. 1, 3 and 4, the panel 16 is folded over on top of the panel 14 by means of the fold line 20. The flaps 28 are then folded inwardly to overlie the panel 16. Thereupon, the panel 12 is folded on top of the flaps 28 and the panel 16 and the glue panel 22 folded under and glued to the bottom of panel 14 for holding the folded unit together. Such structure forms an enclosure for the panel 16 and as seen in FIG. 2 the panel 12 may be provided with a suitable address 64, a return address 66 and a postage stamp 68 for mailing.
If desired, the panels 12 and 14 which are originally connected to the viewer portion panel 16 may be used for purposes other than an envelope, such as for supporting panel 16 as a tear sheet in magazines or books, whereby the printer can assemble the blank with the magazine or books and then said viewer, namely the panel 16, torn out by the consumer. Panels 12 and 14 thus serve in an instance as carrying means, whether serving as an envelope or as support therefor in magazines or books.
To form the viewer, the panel 16 is torn from the remaining portion of the blank. Thereupon, it is folded into the box-like shape of FIGS. 5 and 6 and the tab 60 inserted in the cut line 62 for locking engagement. The
fold lines 42, 44 are formed into square joints whereupon a portion of the viewer will form a rectangular box-like structure with the lens 52 and viewing aperture 54 being substantially horizontally aligned. A slide 56 is then mounted behind the tabs 58 for viewing through the lens. Slide 56 can bea single slide as shown or multiple slides mounted in a single holder and viewed successively in the aperture 54 by lateral movement of the holder. Section 40 serves as a handle for holding the viewer.
The viewer has many surfaces upon which advertising matter can be printed, such as on the face of section 34, the top section 36, the back of section 38, and the projecting or handle portion 40.
FIGS. 7 and 8 show an alternative form of the invention. It comprises a blank 10 the structure of which is the same as the embodiment of FIG. 1 to the extent that it has three main longitudinal panels 12'14' and 16'. The blank 10' also has a narrow panel 22' with a glue surface 26 on one side. The panel 16', as in FIG. I, has individual sections 32, 34', 36', and 40. Section 34 has an aperture 50' for receiving a lens and section 38' has a viewing aperture 54. Section 38 also has tabs 58' for removably supporting a slide, and section 40 has cut lines 62 for receiving a tab 60' on section 32 when the viewer is folded. The viewer panel 16' is provided with fold lines 42', 44', 46 and 48 as in the first embodiment.
Panel 22' is connected to panel 12' by an intermediate narrow panel strip 70 with fold lines 72 being provided on each side of the panel 70. Similarly, panels 12 and 14' are connected together by a narrow panel strip 74, with the connections on opposite sides of the panel strip 70 comprising fold lines 76. Also, panels 14' and 16 are connected together by a narrow panel strip 78, with the panel strip 78 being connected to the panel 14 by a fold line 80 and being connected to the panel 16 by a tear line 82, whereby the panel 16 may be separated from the remaining portion of the blank.
Panel 14' has end tabs 28 connected thereto in spaced relation by strip portions 84 through means of a pair of fold lines 86.
The blank is folded for mailing identical to the embodiment of FIG. 1. The added strips 70, 74, 78 and 84, however, provide a box-like structure when the blank is folded. A folded condition of the viewer is shown in FIG. 8 which comprises a cross sectional view. Such folded box-like construction forms a container which may be used to enclose slides or the like.
The viewer of FIG. 7 is similar to the FIG. 1 embodiment in that when received by the purchaser the panel portion 16' can be torn off on line 82 and folded into the viewer of FIG. 5. i
It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be re sorted to without departing from the spirit of my invention or the scope of the subjoined claims.
Having thus described by invention, I claim:
