SEALING MEANS Filed June 8, 1933 INVENTOR M'ufred AI. .fimaifs ATTORNEY Patented Feb. 20, 1934 SEALING MEANS Winfred M. Brooks, West Orange, N. J.

Application June 8, 1933. Serial No. 674,837

2 Claims.

This invention relates to sealing means, and

has for its main object and feature the provision of a device which it will be exceedingly difiicult to tamper with without leaving thereof.

visible trace In the accompanying drawing the invention is disclosed in a concrete and preferred form in which:

Fig. 1 is a plan View of a sheet material blank, carrying a sealing element, embodying the invention;

Fig. 2 is a detail sectional view substantially on the plane of line 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 1

, but showing the wing portion folded over the main portion;

Fig. 4 is a detail sectional View substantially on the plane of line 4-4 of Fig. 3;

Fig. 5 is a view similar to Fig. 3 but showing the sealing element compressed;

Fig. 6 is a detail sectional View substantially on the plane of line 66 of Fig. 5; and

, but showing a sheet matertion 8 and a connected wing portion 9 which latter is shorter in length than the main portion.

10 indicates a bending line between the two portions, and it will be seen that when the wing portion is folded over the main portion (as in Fig. 3) a part 11' of the main portion is left exposed. Inte grally formed with one of the'side edges 12 of the wing portion is a shank-member 13 that extends first away from said side edge 12 and then in a reverse direction back to a point in line with but beyond free end edge 14 of said wing portion.

The free end of the shank portion is provided with a head 15 having preferably a non-circular Carried on the exposed part of the opening 16. main portion is a body of compressible material 17 corresponding in outline to opening 16. Prefer ably this body of compressible material is secured to the main portion by striking up projections 1 8 in the sheet material and inserting said body in the opening 19 at one side. the wing portion is folded over the thus formed, said body being provided with a head It will now be seen that, when main portion,

body 17 and projections 18 will lie within opening 16, (Figs. 3 and 4).

Body 17 is now compressed (Figs. 5 and 6) thereby holding head 15 in posi- The advantage of this construction is not only 18 over said its cheapness and simplicity but also its tamperproof qualities as will now appear.

If the wing should be severed from the main portion along line 10 then said wing portion would be too large to pass through the hasp or other element to be sealed (not shown), it being only possible to pass head 15 through said hasp. Again, if the shankmember should be severed along line 20 from side edge 12, then it would be impossible to swing said shank-member around body 1'7, because said body and opening 16 form a non-pivotal securing means. Likewise, should the shank-member be severed at line 21, no pivotal movement of the shank-member would be possible.

I claim:

1. Sealing means including: a body of sheet material consisting of a main portion and a connected wing portion shorter in length than, and foldable over, said main portion, to thereby leave a part of the latter exposed, said wing portion having integrally formed therewith, at one of its side edges, a sheet material shank-member that extends first away from said side edge and then in a reverse direction back to a point in line with but beyond the free end edge of said wing portion, the free end of said shank-member overlying the exposed part of the main portion when the wing portion is folded over said main portion; and means to secure the exposed part of the main portion and the free end of the shank-member together when the wing portion has been folded over the main portion.

Sealing means including: a body of sheet material consisting of a main portion and a connected wing portion shorter in length than, and foldable over, said main portion to thereby leave a part of the latter exposed, said wing portion having integrally formed therewith, at one of its side edges, a sheet material shank-member that extends first away from said side edge and then in a reverse direction back to a point in line with but beyond the free end edge of said wing portion, the free end of said shank-member overlying the exposed part of the main portion when the wing portion is folded over said main portion; and non-circular means to secure the main portion and the free end of the shank-member together when the wing portion has been folded over the main portion.
