Description

The invention relates to means for sealing material objects in order to prevent unauthorized access to them.

Famous seal, containing the case in the form of a glass, on the side surface of which there are two openings for the flexible element, and a cover mounted in the housing for rotation, on the inner surface of which the core is made with an opening for the flexible element. The connection of the cover and the housing is threaded. On the outer surface of the cover there is a cross-shaped groove. The flexible element is tied to a sealed object, the ends of the flexible element are first passed from the outside into the openings of the housing, and then into the openings in the core of the lid and tied to a knot. A lid is screwed into the case, a plastic material is applied to the outer surface of the lid, onto which a print is printed with a conventional sign.

The disadvantage of this seal is the possibility of re-use of the seal after its unauthorized opening.

The problem to which the invention is directed, is to ensure the impossibility of reuse of the seal after its unauthorized opening and the possibility of visual control over attempts at unauthorized access to the protected object.

The task is solved by the fact that the seal containing the case with the holes on the side surface, the core with the holes mounted in the case rotatably is characterized in that the case is made transparent in the form of two conjugate cylindrical cavities of different size, the axes of which are perpendicular to each other, the cavities are connected between each other through the groove, the core is provided with ratchet teeth in contact with the longitudinal ribs located on the inner surface of the small cavity, the hands are located on the end of the core The nut is made with the possibility of separation from the core, the holes on the side surface of the housing and in the core are coaxial, in the middle part of the core there is an annular cavity formed by two annular projections, in a large cavity there is an insert with a protrusion ending in a flexible tongue entering the annular cavity of the core through a through groove, and a plate for informational messages is located above the insert.

The technical result of the invention is to improve the protection of the seal against unauthorized opening, the possibility of visual control over the integrity of the seal, expanding the functionality.

The implementation of the body of the seal in the form of two differently sized conjugate cavities and the supply of one of them with an insert with a protrusion that terminates in a flexible tongue entering the annular cavity of the core through the through groove connecting the cavities of the body ensures reliable fixation of the core in the body by preventing its axial displacement.

Supplying the core with ratchet teeth in contact with the longitudinal ribs located on the inner surface of the body ensures that the core rotates only in one direction, which prevents weakening the tension of the flexible element and pulling its ends out of the body when attempting unauthorized access to the seal.

The manufacture of a seal from a transparent material allows you to visually monitor the presence of a flexible tongue in the annular cavity of the core, which indicates that no unauthorized opening of the seal was attempted.

In addition, the presence of a plate rigidly fixing the insert in a larger cavity allows its surface to be used to place any necessary information and thus expand the functionality of the seal. For the same purpose, you can use the lower part of the liner.

The presence of the handle located at the end of the core for its rotation, allows you to do without additional tools, such as a screwdriver, as in the prototype, the possibility of its subsequent separation from the lid eliminates the possibility of opening the seal without compromising its integrity.

The invention is illustrated by drawings.

FIG. 8 shows an embodiment of FIG. 2

The seal consists of a housing 1, made in the form of two conjugate different-sized cylindrical cavities, a small 2 and a large 3, the cavities are interconnected through a groove 4, the core 5 is placed in the cavity 2, to the end of which is attached a handle 6 for rotating the core with the possibility of further separation from the core by means of thinning 7. The core is provided with ratchet teeth 8 in contact with protrusions 9 located on the inner surface of cavity 2, and has two holes 10. On the side surface of cavity 2 there are 4 holes 11 for flexible element 12, coaxial with the holes 10 of the core 5. In the central part of the core 5 there is an annular cavity 13 formed by annular projections 14 of the core. The cavity 3 is provided with an insert 15 provided with a protrusion 16 and a flexible tongue 17 entering the annular cavity 13 of the core 5 through the through groove 4 to prevent axial displacement of the core, and above the insert 15 there is a plate 18 for fixing the insert and placing informational messages on it. An embodiment of a plate 18 with a coating 19 is shown in FIG. eight.

The seal is prepared for work as follows. The core 5 is inserted into the cavity 2 of the housing 1, obtained by the method of casting from a transparent plastic material, then the liner 15 is placed in the cavity 3 so that the protrusion 16 passes through the groove 4 and the flexible tongue 17 enters the annular cavity 13 of the core 5. Then 15 install the plate 18 by gluing or pouring it with plastic mass, forming a permanent connection. Preliminary information may be applied to the surface of the plate. One end of the flexible element 12 is loaded into the hole 11 of the cavity 2, having previously aligned it with the hole 10 of the core 5, then with the handle 6 one or two clockwise turns are made, fixing the flexible element on the core. The seal is ready to go. Due to the presence on the core 5 of the ratchet mechanism consisting of ratchet teeth 8 and transverse ribs 9, the handle 6 can rotate only in one direction, and thus the end of the flexible element inserted into the seal body cannot be pulled back without damaging the case. In this position, the seal is supplied to the consumer.

Installation of the seal on the object

The consumer passes the free end of the flexible element 12 through the holes or ears of the object being sealed and then through the opening 11 of the housing and the hole 10 of the core, then rotates the core 5 in the cavity 2 with the handle 6, winding the flexible element onto the core until it is completely tensioned. Then the handle 6 at the point of thinning 7 is broken off from the end of the core.

The seal thus installed reliably protects the object being sealed from unauthorized opening. Visual observation of the position of the flexible tongue in the annular cavity of the core provides objective information about the integrity of the seal. The absence of a flexible tongue in the annular cavity with the integrity of the remaining elements of the seal indicates unauthorized access to it.

Re-use of the seal after its authorized or unauthorized opening is impossible, because opening the seal is possible only if the tongue or flexible element is destroyed.

The seal is simple in design, easy to manufacture, reliable and easy to operate.
