ENVELQP SBPEGIFIQA'EION forming part of Letters iatent No. 754,201, dated March 8, 1904A Applicationliled lllovembsr 4,1002. Serial 130,112. (No modeld To all whom it may concern.-

Be it linown that I, PEDRO mvms, hcith' zen of the Republic of Peru, and a resident of Havana, Cuba, have invented a new and improved Envelop, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide an improved means for facilitating opening envelops, wrappers, and other like covers of packages, particularly those covers which are used on maitmatters, This end I attain by forming a tearing-strip of the material-of which the envelop itself is formed, thus not only chespening the production of the selfopening envelop in regard to the cost of materiahbut also in regard to the work or labor;

necessary in constructing the envelop.

This specification is an exact descriptionof invention, while the claim defines the actualscope thereof.

Reference is to he had to the accompanying s, fori'nii'ig part of this specification, in v. hich sizniiar characters of reference indi cate corresponding parts in all the figures.

Figure 1 shows one form of envelop and illustrates the manner of securing the tearingw strip thereto, and Fig. 2 is an illustration of a slightly-modified form of envelop.

Referring now to :Fig. 1 of the drawings, a indicates the front of the envelo the two side flaps being designated by b while 0 indicates the bottom flap, the top or sealing flap being designated by If. The tearing-strip (designated by c is formed integral with the den, this being effected by folding the elongated and of the flap inward upon the body nortion of the flap and forming the tearingstrip by a cut f running along the flap. The body part of the flap may be formed with a tongue lying outward immediately in' front 0f the free end of the tearing-strip, and the eX-if In Fig. 2 I have shown a form of the invention which is particularly applicable to a news* paper-wrapper. in this construction the flap is bent inward, and the edge is folded upon itself once or several times, as may be desired, thus forming a tearing-strip e which lies inside of the mucilage attached to the wrapper for the purposeof scaling it. f indicates the slit which severs the tearing-strip from the body of the wrapper, and said body of the wrapper is formed with notches it, producing a tongue which lies inside of the free end of the tearing-strip and facilitates grasping said strip.

It will be observed that an envelop such as herein described possesses many advantages and also modifies the essential features of cheap ness and convenience. It will further be understoodnthat certain changes may be made in the forimproportions, and minor details of my invention without departing from the spi'rit and scope thereof. 'HenceI consider myself entitled to all such variations that may liewithin the intent of theclaimu In the'hccompanying claim I use the term envelop as synonymous with any form of the wrapper or circular for packages.

Having thus described my invention, I claim as new and desire to secure by Letters Patent An envelop having its sealing-flap folded inward upon itself at its free end and having such interfold portion sealed, and a tearing-strip formed integral with and partially severed from the material of the flap, such tearingstrip lying under the outer face portion of the flap, substantially as set forth.

In testimony whereofI have signed my name to this specification in the presence of two suhscribing witnesses.
