WILLIAM F. MIGHLER, OF RHINELANDER, WISCONSIN.
SAFETY-ENVELOP.
Specification of Letters Patent.
Patented Apr. '1, 1914.
Application filed September 3, 1912. Serial N 0. 718,343.
To all whom it may concern:
Be it known that 1, WILLIAM F. MIOHLER, citizen of the United States, residing at Rhinelander, in the county of Oneida and State of Wisconsin, have invented certain new and useful Improvements in Safety- Envelops, of which the following is a specification.
This invention relates to improvements in safety envelops designed to prevent surreptitious access to an envelop after it has once been sealed, or to prevent an envelop being opened and re-sealed without exposure, and has for one of its objects to improve the construction and increase the efficiency and utility of devices of this character.
Another object of the invention is to provide a simply constructed envelop which does not materially increase the expense or weight and which does not detract from the appearance of the envelop or render the same unmailable.
With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention: Figure l is a view of the envelop in open position or ready to receive its con tents; Fig. 2 is a view representing the envelop closed and sealed.
The improved envelop may be constructed of any suitable material and of any suitable size and is readily applicable without structural change to various forms of envelops in which a sealing or closure flap is employed, and, for the purpose of illustration, is shown applied to a conventional envelop comprising a body portion 10, end flaps 11-12, a front flap 13, and a closure flap 14. The front flap 13 is of less width than the body portion 10 and is provided with clefts spaced apart in its outer edge whereby a tongue 15 is produced, while the closure flap 14 is provided with a projecting tongue 16less in width than the tongue 15. The end flaps 11-12 are folded upon the body 10, while the front flap 13 is folded over the folded end flaps and sealed thereon in the usual manner. When thus arranged, the envelop presents the appearance as shown in Fig. 1, and the total width of the closure flap 14 corresponds to the distance between the fold line 17 between the closure flap and the body 10 and the root or bottom portion of the tongue 15, so that when the closure flap 14 is folded into closed position the tongue 16 can be thrust beneath the front flap 13 below the root of the tongue 15 of the outer edge of the closure flap even with the bottom or root of the tongue 15. The closure flap 14 is provided with the usual adhesive, represented at 18, while the inner face of the tongue 15 and the outer face of the tongue 16 are likewise provided with an adhesive. With an envelop thus constructed, after the contents have been placed therein, the tongue 15 is folded upon the lower portion of the front 13 and the adhesive 18 of the closure flap 14 moistened and the adhesive of the tongue 16 also moistened and thrust between the contents of the envelop and the lower portion of the front 13 with the moistened adhesive side against the inner face of the front 13. Pressure is then applied to the closure flap and the portion of the front flap which is located externally of the tongue 16. The adhesive of the tongue 15 is then moistened and the tongue folded upon the folded closure flap and pressure applied to cause the adhesive ma terial to adhere. By this means, the envelop is effectually sealed and can be opened only by destroying one or both of the relatively fragile tongues.
l/Vhat I claim is:
An envelop including a body, end flaps, a front flap and a closure flap, said front flap having clefts spaced apart, slits extending inwardly from the clefts in parallel spaced relation to each other, a tongue extending beyond the outer edge of the closure flap with the sides thereof extending in parallel relation and of less width than the distance between the clefts of the front flap, the closure flap being insertible in the clefts and through the slits and the tongue insertible beneath the front flap in advance of the inner ends of the clefts.
In testimony whereof I affix my signature in presence of two witnesses.
