ENVELOP.

Specification of'Letters'Patent. Patented Nov. 16', 1 920.

Application fil'ea'n' rn 22, 1919. Serial No; 291,341.

ToaZZ 10 71077156 may concern v Be it known thatI, C HAR LIE CaH IOKAM, a citizen of the United States; residing at Portsmouth, in the county of Norfolk and State of l irginia, have invented certain new and useful Improvements in Envelope, of which the following is a specification. V

This invention relates to mailing envelops and more particularly to improvements in the safety type, the primary object of the invention being to provide an envelopwhich when once sealed, cannot beop'ened with out detection or without mutilation ofo'rie or more of the flaps of the envelop.

A further object of the invention is to provide an envelop of thistype'which may be readily nd conveniently sealed and.

which if desired may be placed upon the market partly sealed so as to render it'more convenient for the purchaser to complete the sealing thereof.

In the accompanying drawings:

Figure 1 is a perspective view of the envelop embodying the invention;

Fig. 2 is a longitudinal sectional view on the line 22 of Fig. 1;

F Fig. 3 is a similar view on the line 3-3 of Fig. & is a plan view of the blank from which the envelop is formed.

The envelop comprises a front 1, a back 2, a closure flap 3, and end flaps 4. The front 1 is of the usual form and the back 2, closure flap 3, and end flaps 4 are integral with the edges of the said front as is ordinarily the case. The envelop is formed up from the blank shown in Fig. l of the drawings and in order that an understanding may be had of the invention I will first describe the construction of the several parts of the envelop and then describe the manner in which the envelop is folded up from the blank.

The back 2 near each lateral edge is formed with an incision 5 defining a sealing tongue 6 the connected end of which is located next adjacent the respective lateral edge of the said back and upon the inner face of each of these sealing tongues there is provided an dhesive area 7 a similar area 8 being provided along each lateral marginal portion of the inner face of the back and the said face of the back being further provided with continuations 9 of the adhesive areas 8 which continuations extend from theouter corners of the said back fora short distance along the outer marginal portion of the back; These extension areas 9, however, are'not of greater length than the width of the respective end flaps4 for a reason which will be presently explained. The back 2'isalso formed with a transverse incision 10 located midway between its lateral edges and between the incisions 5 which provide the sealin tongues 6.- 1

The closure flap 3 is formed with an incision 11 providing a sealing tongue 1-2having applied upon its inner face an area of adhesive 13, the attached end of the tongue being locatednext adjacent the outer margin of the saidflap and'the said t'ongue'being v located relatively close to the flap. The incision 10 and the line of union of the tongue 12' with the flap 3 are so located that in the folded condition of the blank these two parts will be brought into registration. There is also provided upon the inner face of the sealing flap 3 adhesive areas or zones 14 and 15 extending respectively along the outer marginal portion of the flap and the lateral marginal portions thereof. Each end flap 4: is formed with an incision 16 extending longitudinally thereof and parallel to the lines of fold between these end flaps and the lateral edges of the front 1 of the blank, these incisions 10 and the lines of union of the sealing tongues 6 with the back 2 being so located that in the folded condition of the blank these parts also will register.

In forming up the envelop from the blank the end flaps 4 are first folded in against the inner face of the front 1, the back 2 being then folded to position against the outer faces of the said end flaps. Before the back is brought to this position the adhesive areas 7 are moistened and as the back is folded to the position stated the sealing tongues 6 are inserted through the respective incisions 16 and are folded back from the interior of the envelop so that their moistened adhesive.

areas or Zones will lie against the inner faces of the respective end flaps 4. Either at this time or prior to folding up the said back. the adhesive areas or zones 8 and their extensions 9 are moistened and after the sealing tongues have been inserted through the incisions in the end flaps, the back is pressed against the end flaps so as to secure these parts together in the relation stated. Inasmuch as the extensions 9 of the adhesive zones 8 are longer than the .in the factory transmitted has been placed within the envelop, the adhesive area or zone 13 is moistened as are also the adhesive areas or zones 14 and 15. The flap is then folded down and as this is done the sealing tongue 12 is inserted through the incision 10 being folded back in the meantime so that its adhesive area 13 will come into contact with the inner face of the back 2 of the envelop. When 'the envelop has been closed in the manner stated, it will be so effectually sealed that it cannot possibly be opened without detection as for exampleby mutilation of one or an other of the flaps or the back or front thereof. The envelop embodying the invention presents a decided advantage inasmuch as after inserting the tongues 6 or the tongue 12 through their respective incisions and sealing the tongues firmly in place it is possible back,- end flaps, and a closure flap, the end 1 the to turn back the marginal portions of back and closure flap, respectively, en 11- ciently far to permit of moistening of the adhesive areas 8 and 9 and the areas and 15 so that it is not necessary to moisten these adhesive areas prior to inserting the sealing tongues through their respective incisions and'thus the fingers of the person sealing the envelop are not liable to become Ulllilled through contact with these moistened areas.

Having thus described the invention, what is claimed as new is A safety envelop comprising a front,

flaps having incisions and the back havi tongues spaced inwardly from its margin and insertible through the said incisions, the said back having a marginal adhesive area to confront the end flaps when the envelop is closed, the said back having an incision and the said closure flap having a tongue spaced inwardly from its margin and in sertible through the last mentioned incision, the said closure flap having a marginal a. hesive areato confront the outer face of the back when the envelop is closed and l of a width to extend over and cover the met mentioned incisions and sealing tongues.

In testimony whereof I aflix my signature.
