JULIA RADIOS, OF DAYTON, OHIO.
ENVELOP.
Specification of Letters Patent.
Application filed February 20, 1919. Serial No. 278,121.
To all whom it may concern.-
Be it known that I, JULIA Ramos, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio,- have invented certain new and useful Improvements in Envelops, of which the following is a specification.
This invention relates in general to stationery and has special reference to an envelop. r
One object of this invention is the production of a safety envelop which is constructed so as to prevent unauthorized tampering with or opening of the envelop without mutilating the structure so as to allow such action to be easily detected.
Another object of this invention is the production of an envelop whereby the flaps are connected by structures which resemble arrow heads and which have adhesivematerial thereon thus allowing the flaps of the envelops to be sealed, although the arrow heads will easily tear and-thus permit of easy detection of tampering with the flaps in the event such action is taken by an unauthorized party.
One practical form of construction and assembly of the invention will be hereinafter described and is illustrated in the accompanying drawing, in which- Figure 1 is a rear elevation of the envelop showing the flaps in a closed position.
Fig. 2 is a plan view of the envelop, showing the manner in which the end flaps are connected together, the bottom flap being partly broken away.
Fig. 3 is a fragmentary section taken on the line 33 of Fig. l.
Fig. 4 is a fragmentary plan view of one of the end flaps illustrating the manner in which the connection thereof is gummed.
In the preferred embodiment of the present invention about to be described 5 indicates the body of the envelops having end flaps 6 and 7, a bottom flap 8 and a top flap 9 as is usual in the conventional form of envelops now in use.
The end flaps 6 and 7 are broadest at their point of connection with the body 5 and taper toward their ends, as indicated clearly in Figs. 2 and 4. From the end of each flap 6 and 7 there extends a reduced projection 10 having the rearwardly diverging extensions 11 formed on its outer end and spaced from the end of the flap. Accordingly the projection 10 and the extension 11 disclose as an entirety a substantially shaped arrow head, as shown clearly in Fig. 4. The extensions 11 of the projectioris2 10 of the flaps 6 are gummed as shown at The bottom flap 8 is provided with a longitudinally extending slot 13 formed contiguous to the apex of the flap, the apex being formed by the converging of the outer edges of the flap. Adj acent these outer edges is provided the usual adhesive material 14:.
The top flap 9 is provided with a projection 15 extending from the apex provided by the converging edges of the top flap and the rearwardly diverging extension 16 is provided on this projection 15, the sides of the extension 16 opposite to that illustrated in Fig. 2 being glued, although it is not necessary to show the adhesive material, in
view of the fact that it can be readily under-- stood without such an illustration.
In assembling the envelop or folding the same to a position to constitute a pocket structure subsequently for finally sealing the same for transmission through the mails, the end flaps 6 are first folded to extend substantially parallel to or rest upon the body 5 of the envelop. At this time adhesive material 12 on the arrow head of the flap 6 is moist and then the arrow head of the flap 7 is interlocked with the arrow head of the flap 6, as shown in Fig. 2. This is brought about by the placing of the projections against each other and then by passing the extensions of one projection around to fit upon the opposite sides of the extensions of the remaining projection. This causes extensions of the arrow head of the flap 7 to engage the glued surfaces 12 of the extensions 11 of the flap 6, thus connecting the two arrow heads firmly together and preventing accidental disengagement of the in-v terlocked engagement between these arrow heads as shown in Fig. 2. The adhesive material 14 on the bottomflap 8 is then moistened and the bottom flap is folded to engage the end flaps 6 and 7 and the bottom flap at this time overlaps the greater portion of the arrow headsof the end flaps 6 and 7 to protect the same, as indicated in dotted lines in Fig. 1. Thus the envelop is folded to form a pocket like structure. After the correspondence sheet is folded and placed within the envelop, the adhesive material before referred to upon the arrow head is PatentedDec. 9, 1919.
moistened, as is the adhesive material 17 adjacent the edges of the top flap. The top flap is then folded down to fit upon the end flaps 6 and 7, and upon the bottom flap 8, whereupon the arrow head structure of the top flap is passed through the slot 18 and the adhesive surface of the arrow head is brought to bear upon the inner surface of the bottom flap as indicated in Fig. 3. Accordingly, the envelop is in condition for transmission through the mails, and it is firmly sealed.
From the foregoing description it will be noted that the adhesive material adjacent the edges of the bottom and top flaps by engaging the end flaps and also by the top flaps engaging the bottom flap will cause the envelop to be sealed inthe usual manner. However, owing to the interlocked engage ment of the arrow heads upon the end flaps, and the arrow head of the top flap engages the bottom flap will further seal the flaps in a closed position. Accordingly if some unauthorized party tampers with the flap in an effort to open the envelop it is obvious that the projection of the arrow heads will be easily torn, since the projections are comparatively small and the extensions are com paratively broad and owing to the adhesive material thereon will produce a greater resistance than the strength of the projection. Of course, the authorized party may very easily open the envelop in any desired or usual way. It will therefore be noted that a very simple envelop has been produced which will allow only a minimum amount of paper in production, and thus can be cheaply constructed, although the arrangement of the parts is such as to enable a ready detection of tampering with any of the flaps after the same have been sealed in a closed position.
The foregoing description and the drawings have reference to what may be considered the preferred or approved form of my invention. It is to be understood that I may tom and end flaps, said end flaps tapering toward their free ends, projections extending from the reduced end of said end flaps, rearwardly extending extensions formed on each projection thus providing an arrow like structure upon the end of each end flap, said projections bearing upon each other, and the extensions of one projection being passed around to fit upon the opposite side of the extension of the remaining projection, thus causing the arrow like structures to interlock, whereby said end flaps will be held in a folded condition and means for holding said top and bottom flaps in a folded condition upon the end flaps.
In testimony whereof I aflix my signature in presence of two witnesses.
JULIA RADIUS.
