WILLIAM W. L. AHANA, 0F HONOLULU, TERRITORY OF HAWAII.

ENVELOP.

Specification of Letters Patent.

Patented Jan. 13, 1920.

Application filed January 3, 1919. Serial at. 269,431.

To all whom it may concern:

Be it known that 1, WILLIAM W. L. AHANA, a citizen of the United States, residing at Honolulu in the county of Oahu and Territory of I-Iawaii, have invented new and useful Improvements in Envelops, of which the following is a specification.

This invention relates to envelope, and particularly to openers therefor.

The object of the invention is to provide an opener comprising a severing strand extending along one of the fold lines of the envelo and connected ,at one end with a 'partia y separated portion of the envelop forming a tab, said'tab serving as a grip whereby the thread may be grasped and manipulated to uickly and conveniently fever the envelop a ong the determined fold A further object of the invention is to provide a novel form of tab and mode of connecting the severing strand therewith,

whereby the manipulating end of the strand will be held securely against casual displacement, and whereby the same may be firmly gripped and held for the severin' action.

The invention consists of the eatures of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawing, in which Flgure 1 is a back view of one form of envelop embodying my invention, showing the sealing flap closed.

Fig. 2 is a similar view, showing the tab turned out so as to be gripped for the openini actlon.

1g. 3 is a view similar to

Fi

1 and 2, showmg the sealing flap unsea ed and in open position.

In the present instance I have shown the a plication of the invention to an envelop o 'oblong rectan ar form, comprisin a front 1 and a bee formed of a bottom ap 2, end flaps 3, and a gummed top sealin flap 4, the

flaps

2 and 3 being united an formin with the front 1 the envelo which 1s adapted to be sealed by olding the flap 4 over upon and securing the" same by its gummed-margin to the

flaps

2 and 3. It is, however, to be understood that the inbody vention may be applied to any other form of envelop in connection with which it may be used.

A severing strand 5, composed of cord or wire, is provided for severing the envelop along one of its lines of fold. This strand is glued or otherwise fastened to the envelop along th line of fold. In the present instance I have shown the strand 5 extended along the line of fold between the front 1 and flap 4 for cooperation with an ungummed tab 6 formed as a part of said flap,

but it is to be understood that the tab may be formed as part of any of the other flaps and the strand 5 arranged along the fold line between such flap and the front 1.

The tab 6 is of suitable shape and size to enable it to be firmly gripped between the thumb and forefinger. It is formed at one end of the designated flap, as the flap d, and partially separated at its inner end therefrom'by a (preferably V-shaped) notch 7;

The notch 7 extends from the free edge of the flap toward its fold line. but terminates short of the fold line so as to leave a narrow intact portion 8 between such fold line and the contracted end of the notch. The tab is thus normally held to lie in the plane of the fla 4 but may be turned outward and upwar from the plane of the sealed flap 4,

as shown in Fig. 2, into the plane of the i front 1, in which operation the portion 8 is severed to entirely separate the tab 6 from the flap 4 preparatory to tearing away said tab from the front 1 and separating the front 1 and tab 4 along the intervening fold line 9.

The strand 5' has an end portlon 10 arranged in looped formation and cemented to the underside of the tab 6, thus securing maximum stren h of connection and providing a lurahty. of surfaces whichtmaybe grippe by the operator to enable a firm grip to be obtained. It will thus be understood that the operator may secure a firm gri upon the tab and one end ofthe strand an in an obvious manner may tear the same free from the envelop and quickly and conveniently'rip the envelop open along the fold line 9. Also it will be evident that the structure is simple and may be applied to various types of envelops without materially adding to the cost of manufacture thereof.

Having thus fully described my invention, I claim a An envelop comprising a body having the usual inturned flaps constituting the back of the body, one of said flaps near its extremity and the line of fold thereof being cut from its edge inwardly to a point near the line of fold to form a tab integral with and removable from the said flap, a cord within the body and extending along the line of fold of the said out flap, and the end of said. 00rd being glued to the underface of the said tab.

In testimony whereof I affix my signature.

WILLIAM W. L, AHANA.
