ALBERT IIABERSTROH, OF BOSTON, MASSACHUSETTS.
SPECIFICATION form'mg part of Letters Patent N0. 693,704, dated February 18, 1902.
Application filed November 4, 1901. Serial No. 80,991. (No model.)
To all whom, it may concern:
Be it known that I, ALBERT HABERSTROH, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Mailing-Envelops, of which the following is a specification. Y
This invention relates to improvements in mailingenvelops for the transmission through the mails or otherwise of printed matters, circulars, merchandise, &c., which by their nature require that the envelop shall be so constructed as to be readily opened for the purpose of examining its contents by the postal examiners and as readily closed afterward.
Although the invention is particularly well adapted as a mailing-envelop, it may to equal advantage be used as a sealing device for wrappers, cartons, or packages, &c., that may require sealing and unsealing from time to time as circumstances may require.
The invention is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 is a rear view of the improved envelop shown open and unsealed. Fig. 2 is a longitudinal section on the line 2 2 shown in Fig. 1. Fig. 3 is a rear View of the improved envelop shown sealedand closed. Fig. 4; is a longitudinal section on the line 44 shown in Fig. 3, and Fig. 5 is an interior view of the rear portion of the envelop.
Similar letters refer to similar parts Wherever they occur on the different parts of the drawings.
In the drawings, A is the rear portion of an ordinary envelop, mailing-case, carton, &c., B, and B is the end flap thereon, adapted to be closed over the rear portion A, as usual.
In practice I make on the rear portion A a perforation a, back of which I secure to the interior of said portion A a cemented disk 0, preferably coated with rubber cement or other suitable adhesive or sticky material capable of being stuck to another portion of the envelop, &c., by pressure. I also in practice make a perforation Z) on the end flap B, and on the outside of the latter I secure a cemented disk D, as shown, said disk being coated on its exposed portion with a coating of rubber cement or other suitable adhesive or sticky material. It will thus be noticed that the cemented portions of the disks 0 and D are exposed through the respective perforations a and b in the rear portion A of the envelop and the interior portion of the end flap B.
To seal the envelop, carton, &c., it is only necessary to close the flap B and to press the exposed cemented portion of the disk D against the cemented portion of the disk 0 on the envelop portion A, by which the end flap B is caused to be heldin closed position relative to the rear portion of the envelop, 850.
If it is desired to open the envelop, all that is necessary to do is to take hold of the end portion of the flap B and raise it, causing the cemented portions of the disks 0 and D to separate, thus allowing the contents of the envelop or package, 850., to be examined or removed.
The envelop, wrapper, carton, 860., may be repeatedly closed and opened from time to time in a manner as above described.
Although in practice I prefer to make perforations on the rear portion of the envelop and on the end flap and secure back of such portions cemented disks adapted to be stuck together, as above described, I Wish to state that I do not desire to confine myself to this exact construction, as I may, if so desired, dispense with such perforations in the rear part of the envelop and the end flap and to attach permanently to such parts cemented disks adapted to be stuck together in closing the envelop or package, &c., and instead of attaching cemented disks to such rear part of the envelop and to the end flap I may apply cemented coatings to such respective parts adapted to be stuck together in closing the envelop, wrapper, package, &c., and to be readily disconnected from each other in pulling the end flap. from the main body of the envelop, wrapper, &c., during the unsealing of the same.
What I wish to secure by Letters Patent and claim is- 1. An envelop having its flap and its back provided with a non-hardening cement, for detachably connecting the flap to the back.
2. The combination with the back and flap of an envelop, of a disk of non-hardening cement connected to tho flap, and a disk of non-hardening cement connected to the back and adapted to engage'the disk of the flap for detachably connecting the back and flap together.
3. An envelop provided with a flap having an opening, a back provided with an openin g, a disk of non-hardening cement attached to the outerface of the flap and adapted to project through the opening, a disk of non- 10 hardening cement secured to the inner face of the back and adapted to project through the opening thereof, said disks of cement adapted to engage each other for detachably connecting the back and flap together.
In testimony whereof I have affixed my sig- 15 nature in presence of two witnesses.
