Abstract
Abstract A tamper-proof seal comprising a strap-like body portion generally having sealing means at the ends of the body portion so that the body portion can be placed through a hasp or other locking means to provide a locking element. The body portion is then looped around and fastened by the sealing means at each end thereof to make a permanent tamper-proof seal. The sealing means comprises a socket portion and a plug portion having a frame construction. There is a lateral locking surface in each portion which provides a permanent seal, and there is provision by means of a resilient coupling to make the seal by deforming the lateral locking surface of the plug within the plug frame.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
233 words
A seal comprising an elongated flexible body portion, including socket means and plug means intended for reception in the socket means, said plug means comprising leading end means, trailing end means and side means, all forming closed perimeter means outlining space means central to the plug means, said plug means being comprised of resilient material with at least one lateral locking surface extending from at least one side member of said plug means and at least one complimentary lateral locking surface comprised within the socket means in a through opening thereof, said plug means having an outside configuration from said lateral surface to said trailing end substantially complementary to the corresponding inside configuration of the through opening of the socket means with the cross section area of the trailing end of the plug means formed to be In relatively close tolerance with the cross sectional area of the internal configuration of a corresponding end of the through opening of the socket means, said plug means being substantially enveloped by said socket means in engaged position, in which said side member comprising said locking surface is movable toward said control space means and both mentioned lateral locking surfaces of the plug and the socket cooperate to form deformable resilient coupling means providing a positive seal when said plug means and said socket means are together with said lateral locking surfaces in opposing facing relationship.
Claim 2
Dependent Claim
233 words
A seal comprising an elongated flexible body portion, including socket means and plug means intended for reception in the socket means, said plug means comprising leading end means, trailing end means and side means, all forming closed perimeter means outlining space means central to the plug means, said plug means being comprised of resilient material with at least one lateral locking surface extending from at least one side member of said plug means and at least one complimentary lateral locking surface comprised within the socket means in a through opening thereof, said plug means having an outside configuration from said lateral surface to said trailing end substantially complementary to the corresponding inside configuration of the through opening of the socket means with the cross section area of the trailing end of the plug means formed to be In relatively close tolerance with the cross sectional area of the internal configuration of a corresponding end of the through opening of the socket means, said plug means being substantially enveloped by said socket means in engaged position, in which said side member comprising said locking surface is movable toward said control space means and both mentioned lateral locking surfaces of the plug and the socket cooperate to form deformable resilient coupling means providing a positive seal when said plug means and said socket means are together with said lateral locking surfaces in opposing facing relationship.
Claim 3
Dependent Claim
21 words
A seal as claimed in claim 1 comprising resilient web means positioned within at least a portion of said space means.
Claim 4
Dependent Claim
29 words
The seal as claimed in claim 1, in which the lateral locking surface of the socket means is positioned within said opening in spaced relationship to the socket means.
Claim 5
Dependent Claim
34 words
The seal as defined in claim 1, in which auxiliary cover means are provided to cover the end of the through opening of the socket means adjacent the leading end of the plug means.
Claim 6
Dependent Claim
21 words
The seal as claimed in claim 1, in which the elongated flexible body portion is in the form of a strap.
Claim 7
Dependent Claim
33 words
The seal as claimed in claim 1, in which the elongated flexible body portion is in the form of a filament, and the leading end of the plug means has a nose portion.
Claim 8
Dependent Claim
40 words
The seal as claimed in claim 1, in which the plug means is provided with at least one longitudinal rib and the socket means is provided with at least one longitudinal groove to receive the rib of the plug means.
Claim 9
Dependent Claim
54 words
The seal as claimed in claim 1, in which the frame means of the plug means has a pair of opposed sides of resilient material, each side having a lateral locking surface and in which the socket means comprises a pair of lateral locking surfaces in the form of internally extending diametrically opposed shoulders.
Claim 10
Dependent Claim
65 words
The seal as claimed in claim 8, in which the socket means comprises a pair of locking surfaces positioned to be in facing relationship to the lateral locking surfaces of the plug means when the plug means is within the socket means, said locking surfaces of said socket being disposed on extensions within the socket positioned in spaced relationship to the body of the socket.
Claim 11
Dependent Claim
30 words
The seal as claimed in claim 9, in which the frame means of the plug means is provided with resilient web means within the rectangle form of the frame means.
Claim 12
Dependent Claim
54 words
The seal as claimed in claim 1, in which the perimeter means of the plug means outlines a rectangular space with the side means of the plug means having lateral locking surfaces and in which the socket means comprises a pair of lateral locking surfaces in the form of internally extending diametrically opposed shoulders.
Claim 13
Dependent Claim
52 words
The seal as claimed in claim 8, in which the lateral locking surfaces have inner and outer edges, and the inner edges of at least the lateral locking surfaces of the plug means are positioned closer to the leading end of the plug means than the outer edges of said locking surfaces.
Claim 14
Dependent Claim
194 words
A seal as claimed in claim 12, in which the plug means has at least one bevelled portion between said leading end and said plug means locking surface, and said socket means having at least one bevelled portion within the through opening positioned between its first end and the socket means locking surface, with said deformable coupling comprising at least the locking surface of the plug means and the bevelled portion of the plug means positioned to be engaged by the bevelled portion of the socket means to provide for deformation of the resilient side member of the plug means by engagement of the said bevelled portions during insertion of the plug means into the socket means from the normal shape of the frame of the plug means to a deformed shape wherein the resilient side member is laterally deformed from normal shape toward the center of the plug frame, and when the plug means is positioned within the socket means opening, the bEvelled portion will be disengaged permitting the deformed side member to resume undeformed normal shape with its locking surface in faced opposing position to the locking surfaces of the socket means.
Claim 15
Dependent Claim
