Description

[Detailed description of the invention] The present invention relates to security seals.

It consists of a capsule and an insert body, and when inserted into the capsule by elastic deformation.

A basic security seal is already known from Brazilian Patent No. P 171LI8441, such that it cannot be pulled out of the capsule again without damaging one part of the part. Two grooves are molded into the insert, one groove running along each side of the insert. The grooves are connected by a recess at the end of the insert that enters the capsule.

The grooves and recesses serve to receive filaments or threads that are held connected when the seal is closed in use.

The Brazilian Patent No. PI7108441 is.

An improvement is presented for this type of seal consisting of a filament integrally molded with the capsule or insert. The filament has a free end, and the filament is bent over an orifice in the object to be sealed to a trowel bent over one of the inserts, before the insert is inserted into the capsule. Received within grooves and recesses.

Due to the reduced friction, the above-described seals in their basic form have not been entirely satisfactory in retaining seal filaments of smooth material such that the filaments can be pulled from the seal without opening the seal. . Even if the safety of the seal is not compromised, once the filament is removed, it cannot be returned, so a large fixing force is applied to the filament to prevent it from being removed, and the seal is consumed. We have people publish each magazine.

The main objective of the present invention is to provide a security seal that effectively retains smooth striations to prevent removal.

Another object of the invention is to preassemble the sealing filament with a sealing filament, the sealing filament being considerably longer than the length of the filament that would be obtained if the seal and filament were molded together. The object of the present invention is to provide a basic type of security seal as disclosed in the aforementioned Brazilian patent.

According to the invention, the security seal of the basic type disclosed in the above-mentioned patent is further characterized in that the insert is further molded;
One or more openings hold the insert between the two faces and are curved into the groove.

In one embodiment for use with a plastic filament, the opening in the insert is sized equal to or approximately equal to the cross-section of the plastic filament. during use.

The plastic filament is passed in one direction along the groove on one side of the insert and curved through the opening.

Make one pass in the opposite direction along the groove on the other side of the insert.

In a preferred embodiment, the seal is provided with an integral striation extending from one or the other part thereof, as in the aforementioned patent. In this case, the opening of the insert has a shape equal to or approximately equal to the cross-section of the filament.

In another embodiment, the seal is used with separate pre-assembled filaments. The filament passes along the load in the direction of its free end.

It runs through one opening in the insert and continues along a groove on the other side of the insert at one end. The distal portion of the filament is positioned within the groove in the first side of the insert between the aperture and the distal end. The striations in this example are as follows.

Flexible, preferably metal, made from IJ tubing or wire.

In FIG. 1, a seal according to the invention consisting of a capsule 1 and an insert 2 is shown. The insert 2 has a central stem 6
have. The central stem 6 has grooves 8, 9 and openings 4 on both sides.

The opening 4 passes through the stem 6 and extends into the groove.

The filament 5 is integrally molded into the insert.

FIG. 2 shows a longitudinal sectional view taken along the line X--X in FIG. 1. In FIG. 2, the insert and integral plastic filament are in a position ready to close the seal. The filament 5 passes over the object to be sealed and the free end of the filament is bent through the opening 4 in the stem. The filament 5 is bent, passes through the free end of the insert 2 all the way, and returns facing the same groove 9. The capsule 1 is finally placed on the insert book 2 to complete the sealing process. The filament 5 and the opening 4 have the same cross section.

FIG. 6 shows the insert and preassembled thread. The preassembled filament is made from a flexible material such as a metal wire or strip. The filament 6 curves along the groove 8Vc on one side of the insert, around the opening 4, and continues along the groove 9 on the other side to the upper end 10. The distal end 11 of the filament 6 terminates in a groove 8 on the first side of the insert. The other end 7 of the filament extends away from the insert and terminates in a free end 7. To seal the object, the free end 7 is passed through the object to be sealed and bent along the groove 9, leaving the upper end 10 at 1
Then, it returns to the groove 8 of the insert 2. The capsule is attached to complete the entire sealing process.

The configuration shown in FIG. 6 illustrates another use of a seal with an insert opening. In the special case where the filament is made of a wire or a flat metal strip, its other use does not present the problem of being able to remove the closed seal even without the opening 4. In this case, the opening 4 allows preassembly of one end of the wire or metal strip to the insert, so that the wire or metal strip is not removed from the seal and the preassembled book may be manipulated before use. .

The filaments used in conjunction with the seals of the present invention may be of any length and are not simply limited by the capacity of the monolithic filament mold.

Accordingly, one illustrated embodiment may be used with a filament having a reduced coefficient of friction, effectively retaining the filament within a seal, and pre-assembled filament from durable metal or any other resistance material. Provides a seal that may be used with.
