Seal

Description:

The invention refers to the means for sealing material objects and can be used to control their preservation.

A seal is confined which confines a transparent body with cylindrical cavity with bottom and holes on the lateral surface for the flexible sealing element and a core with coaxial holes with the holes on the side surface of the body. The core is installed in the body with the possibility of rotation and is equipped with ratchets that contact longitudinal ribs executed on the inner surface of the body. On the outer front of the core there is a rotating pin fixed with the possibility of detaching from the core and a plate for informative data. the joint of the lid and the body is made with gypsum. On the outer surface of the lid a crucifix groove is executed. The flexible element attaches to the sealed object, the ends of the flexible element are first inserted from the outside into the holes in the body, and then into the hole in the middle of the lid and renewed. the closure of the body is performed by screwing the lid, a plastic material is applied to the outer surface of the lid, which is printed by pressing о stamp with a conventional sign [1].

The disadvantage of this seal is the possibility of repeated use of the seal after its unauthorized release.

The problem solved by the present invention is to ensure the impossibility of repeated use of the seal after its unauthorized opening and the possibility of performing the visual control over the attempts of unauthorized access to the protected object.

The device according to the invention removes the disadvantage mentioned above by including a transparent body with cylindrical cavity, with bottom and holes on the lateral surface for the flexible sealing element, a core with holes, coaxial with those on the lateral surface of the body, the core being installed in the body with the possibility of rotation and equipped with ratchets that contact with longitudinal ribs executed on the inner surface of the body, on the outer front of the core there is a rotating wound fixed with the possibility of detachment from the core, or plate for informative data. The novelty is that the additional device is equipped with a bottom cavity disc, in which the said plate for informative data is located, the disc being joined to the body so that the plane of the disc is parallel to the longitudinal axis of the cylindrical cavity of the body, the cylindrical cavity communicating with the cavity the disc through a through groove, at the same time the middle part of the core confines an annular channel formed by two circular edges, and in the cavity of the disc is placed a protruding bush that holds with a flexible ratchet that enters the annular channel of the core through the perforated groove. In addition above the plate for informative data is placed a protective coating made of transparent plastic.

The result of the invention consists in increasing the degree of protection of the seal by equipping it with о bushing with flexible ratchet that does not allow to extract the core from the body without producing visible damage to the body or flexible ratchet.

Execution of the body of the seal in the form of two cavities: the cylindrical cavity and the cavity of the disc, the latter being equipped with a protruding bush which is held by a flexible ratchet, which enters the annular channel of the core through the through groove, ensures a secure fixation of the core in the body. , due to the prevention of its axial displacement.

Providing the core with ratchets that contact the longitudinal ribs executed on the inner surface of the body, ensures that the core is rotated only in the ο direction, which does not allow loosening of the stretched flexible element and removing its ends from the body in the event of unauthorized access to the seal.

The manufacture of the seal made of transparent material allows to visually control the presence of the flexible ratchet in the cylindrical cavity of the core, which proves that the seal is intact, alias, no unauthorized attempts have been made.

The information plate placed in the bottom cavity disc allows to use the surface for the placement of any necessary informative data and, thus, to extend the functional possibilities of the seal.

The presence of the handle located on the front of the core for its rotation does not require additional tools, such as the screwdriver in the nearest solution, ensures the possibility of detaching it from the core and excludes the possibility of removing the seal without causing damage to its integrity.

The invention is explained by the drawings in fig. 1-8, which presents:

The seal includes a body 1 made in the bottom of two cavities: the cylindrical cavity 2 and the cavity of the disc 3, the cavities are joined by a groove 4, in the cavity 2 is located a core 5, on the front side of which is fixed a rotary fin 6 with the possibility of detaching it from the core by means of a thin 7. The core is provided with ratchets 8, which contact with longitudinal ribs 9 executed on the inner surface of the body 1 with two holes 10. On the lateral surface of the cavity 2 there are four holes 11 for the flexible sealing element 12, coaxial with the holes 10 of the core 5. In the middle of the core 5 an annular channel 13 is formed, formed by two circular edges 14 of the core. In the cavity 3 is located о bush 15 with о protrusion 16 which is held by a flexible ratchet 17 which enters the annular channel 13 of the core 5 through the through groove 4 in order to prevent axial displacement of the core. Above the bush 15, located in the cavity of the disc 3, is located о plate 18 for informative data with о protective covering of transparent plastic grill 19.

The way the seal is assembled.

In the cylindrical cavity 2 of the body 1, obtained by the transparent molding method, the core 5 is mounted, then in the cavity of the disc 3 the bush 15 is located so that the projection 16 passes through the through groove 4 and the flexible pawl 17 enters the channel ring 13 of the core 5. Next, the plate 18 is installed on the plate 18 by gluing or coating it with a plastic grinder 19, forming a non-removable connection. Previously, informative data can be applied on the surface of the plate 18. One end of the flexible element 12 is inserted into the hole 11 of the cavity 2, pre-accumulating it with the hole 10 of the core 5, and then with the handle 6, one - two rotations are made after the needles of the ceasome, fixing the flexible element on the core. Thus, the seal is ready for use. Due to the presence on the core 5 of the ratchets 8 and the longitudinal ribs 9, the handle 6 can only be rotated in one direction and thus the end of the flexible element inserted in the body of the seal cannot be pulled back without destroying the body. In this position the seal is fumigated to the beneficiaries.

The seal is installed on the object as follows.

The beneficiary passes the free end of the flexible member 12 through the holes or ears of the sealed object and then through the hole 11 of the body and the hole 10 of the core, and then rotates the core 5 into the cavity 2 with the aid of the handle 6, winding the flexible element on the core until the full extent of his. Then the handle 6 instead of the subfolding 7 breaks from the front end of the core.

The seal installed in this way certainly protects the sealed object from unauthorized business. The visual control of the position of the flexible ratchet in the cylindrical cavity of the core presents an objective information regarding the integrity of the seal. The lack of the flexible ratchet in the cylindrical cavity in the case of the integrity of the other elements of the seal, speaks of the unauthorized access to it.

Repeated use of the seal after its authorized or unauthorized disassembly is impossible as the disassembly of the seal is only possible by destroying the body or flexible element.

The seal is simple from the constructive point of view, technologically from the manufacturing point of view, comfortable and reliable.
