ENVELOP-SEAL.
Specification of Letters Patent.
Patented Mar. 19, 191.8.
Application filed August 1, 1917. Serial No. 183,927.
T 0 all whom it may concern:
Be it known that 1, JOHN M. FLo'r'rMAN, a citizen of the United States, residing at Butte, in the county of Silverbow and State of Montana, have invented new and useful Improvements in Envelop-Seals, of which the following is a specification.
This invention relates to sealing devices especially adapted to be used on envelops or similar containers and it consists in the novel features hereinafter described and claimed.
An object of the present invention is to provide novel means for sealing an envelop or other container, without the assistance of glue, paste or other adhesive, and whereby the envelop or container cannot be opened without detection.
It, is also the object of the present inven tion to provide a simple and inexpensive closure which will not encumber the envelop or container, and which will permit the container to be readily sealed or closed, in a positive, reliable and efiicient manner.
With the above object in view the invention consists in providing upon the flap of the envelop a tongue adapted to be tucked through a slot provided at the back of the envelop, the said back of the envelop and the tongue having unique interengaging means for locking the tongue and flap against withdrawal with relation to the back of the envelop. The parts of the seal are so arranged that they may be conveniently used at the end of the envelop or in the vicinity of the lower edge thereof and two or more sealing devices may be employed if desired.
In the accompanying drawing Figure l is a plan view of an envelop showing the sealing device applied.
Fig. 2 is a similar view of the envelop showing the flap in an open position.
Fig. 3 is a transverse sectional view of the envelop cut on the line 3-3 of Fig. 2.
Fig. 4; is a plan view of a frame used on the envelop.
Fig. 5 is a similar view of hooks used on the envelop.
As illustrated in the accompanying drawing, the envelop 1 is provided with the usual sealing flap 2. The said flap is provided at its free edge with a tongue 3 and a frame 4 is applied to the inner surface of the said tongue. The said frame is preferably formed from card board, bristol board or similar relatively heavy and thick paper, and the inner surface of the frame 4 is covered by a relatively thin strip of paper 5. The frame a is provided with a slot 6 which leads into the said frame from the lower end thereof and which is provided with converging side walls or edges 7. The frame a is provided at the upper end of the slot with laterally disposed recesses 8, the lower walls or edges of which constitute shoulders 9.
The back of the envelop 1 is provided with a slot 10 and the shanks of hooks 11 are secured to the inner surface of the back of the envelop and beyond the ends of the slot 10. The inner portions of the hooks 11 pass through the slot 10 and the bills of the hooks are located beyond the outer surface of the back of the envelop and are disposed in opposite directions.
When it is desired to seal an envelop the flap 2 is folded down and the tongue 3 is passed through the slot 10. At the same time the free ends of the hooks 11 pass between the tongue 3 and the strip 5 and between the converging edges or walls 7 of the slot 6. When the bills of the hooks arrive opposite the recesses 8, they spring into the said recesses and catch over the shoulders 9 whereby the flap is securely locked and held in a closed position with relation to the body of the envelop. In order to open the envelop it is necessary to mutilate or tear some of the parts in order to sever the flap from the body of the envelop or to disconnect the hooks from the frame.
From the foregoing description taken in conjunction with the accompanying drawing, it will be seen that an envelop closure of simple and durable structure is provided and that the same when applied and locked will hold the parts in inter-engagement with each other in the absence of an adhesive and that the contents of the envelop cannot be removed from the same without tearing or mutilation.
Having described the invention what is I slot, the said hooks being extended through the slot and having bill ends located beyond the outer surface of the back and disposed in opposite directions, the bill end portions of the hooks being disposed at angles to the shank portions thereof, the flap of the envelop being provided With a tongue, and a frame carried by the tongue and having a slot, adapted to receive the bill ends of the hooks, the said frame being provided at its 19 upper portion With recesses and shoulders located below the said recesses.
In testimony whereof I aifix my signature. JOHN M. FLOTTMAN,
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
