SEUHG I. HAHN, F PHILADELPHIA., PENNSYLVANIA ENVELOPE Application iled April 80, 1931. Serial Io. 531,581?.

This invention relates to an improved envelope and has more particular reference to accessory embodied in one end thereof to facilitate removal of the contents without 6 danger of mutilating or tearing the contenta More ilically stated, the invention is predica upon a new type of envelope opener of the kind constituting an integral part ,of the envelope itself.

My principal aim is to generally improve upon articles of this type by providing a. danger of mutilating or tearing the contents practical form of envelope opener characterized b simplicit and economy and capable of fulfilling the result in a more satis factory manner than is accomplished with the present type of openers with which I am now familiar.

In the drawings:

Fi re 1 is a rear elevational view'of an enve ope constructed in accordance with the present invention.

Figure 2 is a view like Figure 1 showing the top or closing flap in its normal open posi tion.

Figure 3 is a view like Figure 2 showing the improved opener in the process of consti-ucr tion.

Fi e 4 is a view like Figure 1 showing the u' envellge o ner torn oli' with the contents Ezxirtly wi drawn and illustrated in dotted Figure 5 is a section on the line 5-5 of Figure 1.

Figure 6 is a horizontal section on the line 6-6 of Figure 2.

Fi re 7 is a perspective view of one of the detail.. Figure 8 is n perspective view of another one of the details. In the drawings in Figures 5 and 6 for example the envelope as a whole is indicated by the numeral 9 and comprises the usual a front wall 10 and as seen in Figure 2, the

ed closin flap is denoted by the numeral 11 and t e enel sections 12 and 13 are fastened toget er along their meeting ed to form the back wall.

he lower end portion of the envelope is revised to incorporate the features of this 'and 13 (illustrated in F ure 5).

invention and I first call attention to the numeral 14 which designates the bottom clos ing lia This has its inner surface coated withgiue or other adhesive material as illustrated in Figure 3. It is approximately 56 rectangular in configuration and for sake of illustration of the principle of the invention maf-' be said to comprise an upper section 15 an a lowersection 16. The section 16 is olpposed to a corresponding lower part 17 of 60 t e front wall 10 and these features 16 and 17 are joined by the fold or bend 18 forming the4 bottom of the envelope. In acordance with the' invention I rovide sn opener strip 19which may be of fa ric or other equivalent ed material. This is fastened to the glue on the inner surface of the lower section 16 but is not attached to the panels 12 and 13. The numeral 2O designates a guide and reinforcing strip of heavy paper or the like which is 7o glued to the outer surface of the section 15 and this strip has its ends 21 beveled on the approximate angle illustrated in the drawings. The purpose of these bevels is to form clearance spacesat opposite ends of the strip 75 to facilitate gripping ci the end portieri of the section 16 for downward and then lateral pulling. The lower ed e of this strip 2G orrns a straight edge w ich guides the tearinv or o ninU operation of the envelope. so tIn ma ing the envelope it is observed that the portion 17 of the front wall 10 does not extend below the lower ends of the anels 12 ssumin that the flap 14 is swung own to the ilatposi- 85 tion illustrated in Figure 3 it is obvious that the fabric strip 19 is glued to the innerisurface of the part 16. Then the part 15 is swun up and fastened to the adjacent lower en portions of the anels 12 and 18. Next the 90 strip 20 is glu across the outer surface of the part 15 so that it will serve as a reinforcing member as well as a. straight edge for tearing purposes. By catching a hold of either end of the strip equipped section 16 95 and tearing crosswise on a line with the lower edge of the guide strip 20, it is obvious that the lower end portion of the 'envelope can be torn awa Without disrupting the contents of the enve ope, Incidentally in Figure 6 l 30 have shown the features 16 and 19partly torn and led back to indicate the manner in which tearing is accomplished for conveniently exposed the contents of the envelope.

It is thought that the description taken in conection wlth the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary. l

While the referred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

Havin thus described my invention, what I c aim as new is:

In an envelo e, a front wall provided at one end thereo with a flap having an adhesive a back Wall embodying overlapping panels iatly engaged by the e ge portion of said flap, an envelope opening stri between said Hap and the panel of said bac wall and positioned adjacent the point of connection of said flap with said front wall, and a reinforcing strip secured to the outer surface of said flap and havin a spaced lower edge in spaced parallel relation to one edge of said envelope opening strip, the end ortion of said reinforcin and guide strip ing extended an lar y in from the sides of the envelope to acilitate tearing.

In testimony whereof I ax my si SEUNG K.

atune.
