A safety cap for a bottle includes a cover fastened by means of the thread on an outer bush, which is connected by edges to an inner bush forming the passes, a metal casing consisting of two parts, one part of which is installed on the cover, and another is installed on the outer bush. A checking indicator collar is made along the perimeter of the lower edge of the cover, the adjacent edges of the parts of the metal casing are folded in the checking indicator collar with the possibility of releasing one of the casing edges when the cover is being turned on. Along the perimeter of the lower edge of the cover from the inner part thereof on the level of the indicator collar an additional collar is made, which thickness exceeds the thickness of the indicator collar, and the indicator collar and the additional collar are made as a whole with the cover forming a gap between the edges of the indicator collar and the additional collar. The width of said gap, after the releasing one of the metal casing edges when the cover is being turned on, exceeds the width of said gap when the cover is initially closed. The invention provides to improve the reliability of the protection of the bottle from the adulteration of the content of the bottle corked up by the safety cap, and also to improve the reliability of the repeated closing in partial use of the liquid in the bottle.

Description

The invention relates to closures for containers with liquids having a means of indicating the opening.

Known safety cap for the bottle, containing a screw cap, mounted by thread on the outer sleeve connected by ribs with the inner sleeve and with the formation of flow channels, the elastic element with a through hole and protrusions forming an upper part of the annular cavity located in it with the lower part of the inner sleeve with the formation of a gap between the bottom and the protrusions of the elastic element, consisting of two parts, a metal casing, one of the parts of which is mounted on the cover and the other on the outside sleeve along the perimeter of the lower edge of the lid is made indicating aureole, the metal casing are made in contact and their edges seamed into the control indicator collar, with release one of said edges at unscrewing of the cover (CI 2225337 C1, 10.03.2004).

This known device has the following disadvantages.

Thus, it is possible to reuse the container corked by this safety cap with indicator rim, which, in the process of unauthorized opening of the screw cap, was released from one of the seamed edges of the metal casing, by returning it to its original state, when screwing the screw cap (already opened bottle), that is, the whisk can be brought back under the free rolled-in edge of the metal casing using, for example, a teaspoon or other similar object. In this case, the cap of the bottle will not indicate that there has been a violation of the integrity of the factory bottle capping.

In addition, when the fluid in the bottle is partially used after opening it, the screw cap cannot be completely re-screwed, as the control indicator rim of the screw cap rests against the outer edge of the metal casing when tightened. All this leads to unreliable (incomplete) closing of the bottle and leakage of liquid from it when the closed bottle is tilted.

Thus, this well-known design of the safety cap does not provide reliable protection of the bottle against falsification of its contents, as well as hermetic repeated closure with partial use of the liquid in the bottle.

The technical result of the proposed invention is to increase the reliability of its protection against the falsification of the contents of the bottle that is sealed with this cap, as well as to increase the reliability of its repeated closure with partial use of the liquid in the bottle.

This is achieved by the fact that in a safety cap for a bottle, including a cap, fastened by thread to an outer sleeve connected by ribs with an inner sleeve with the formation of flow channels, a two-piece metal casing, one of which is mounted on the lid and the other on the outer sleeve, along the perimeter of the lower edge of the lid, a control indicator rim is made, the adjacent edges of parts of the metal casing are folded into a control indicator rim with the possibility of releasing one and When the cover is unscrewed, an additional rim is made around the perimeter of the lower edge of the cover from its inside at the level of the indicator rim, the thickness of which exceeds the thickness of the indicator rim, while the indicator and additional rims are made in one piece with the cover to form between the edges of the indicator and additional corners of the gap, while the width of this gap after the release of one of the edges of the metal casing when unscrewing the cover exceeds the width of the same gap when lid closed.

In addition, the indicator and additional corollas are made with the formation between them of an acute angle after the release of one of the edges of the metal casing when unscrewing the cover.

In addition, the adjacent rolled-in edges of the metal casing are placed with a gap.

In addition, the adjacent rolled-in edges of the metal casing are interconnected by bridges with weakened strength ensuring the bridges break when the cover is unscrewed.

The invention is illustrated in the drawings, where in FIG. 1 shows a safety cap for a bottle, with the lid closed, in FIG. 2 is a view I in FIG. 1, in FIG. 3 shows a safety cap for a bottle, with the lid open, in FIG. 4 is a view I in FIG. 3, in FIG. 5 shows a safety cap for a bottle, with the lid closed when re-closing a previously opened bottle; FIG. 6 is a view I in FIG. five.

The safety cap for the bottle includes a cap 1, an outer sleeve 2, an inner sleeve 3, a metal casing consisting of two parts 4 and 5, one of which is 4, mounted on the cover 1, and the other 5 is installed on the outer sleeve 2.

The cover 1 is fixed on the outer sleeve 2 by means of the thread 6, which in turn is connected by ribs 7 with the inner sleeve 3 with the formation of the passageways 8.

Along the perimeter of the lower edge of the cover 1 (from its outer part) there is a control indicator corolla 9, and from the inside of the cover 1 at the level of the indicator corolla 9, an additional corolla 10 is made.

Adjacent edges 11 and 12, respectively, of parts 4 and 5 of the metal casing are rolled into a control indicator rim 9 with the possibility of releasing one of the edges (in this case, the edge 12) when the cover 1 is unscrewed.

Indicator and additional rims, 9 and 10, respectively, are made in one piece with the lid 1 with the formation between the edges of the indicator and additional rims of the gap with. The width of this gap after the release of one of the edges (edges 12) of the metal casing when unscrewing the lid 1 exceeds the width of the same gap with the lid initially closed.

Indicator and additional rims, respectively 9 and 10, are made with the formation between them of an acute angle α after the release of one of the edges (edge 12) when unscrewing the cover 1.

Adjacent seamed edges 11 and 12 of the metal casing can be placed with a gap (Fig. 1 and 2).

Adjacent seamed edges 11 and 12 of the metal casing can be interconnected by jumpers (not shown in the drawings), which have a weakened strength, which ensures the breakage of the bridges when the cover 1 is unscrewed.

The device works as follows.

When unscrewing the screw cap 1, the control indicator rim 9 is released from one of the rolled edges 12 of the metal casing.

When the bottle is tilted (not shown), the liquid enters the passage channels 8 and flows out of the bottle.

The control indicator rim 9, which, in the process of opening the screw cap 1, was released from one of the rolled edges 12 of the metal casing, when screwing on the cap 1 (already opened bottle) cannot be returned to its original state, since the additional rim 10 of the cap 1, whose thickness exceeds the thickness of the indicator rim 9, strengthens the design and does not allow the indicator rim 9 to be brought back under the edge 12 without damaging it. In this case, the cap of the bottle will clearly indicate that there has been a violation of the integrity of the factory bottle capping.

In addition, with partial use of the liquid in the bottle after opening it, there is a tight subsequent (or subsequent) closure. This is achieved due to the increased gap after opening the bottle (initial unscrewing of the lid 1) between the edges of the control and additional rims 9 and 10 of the lid 1 and the release of the freed edge 12 of the metal casing when the lid is screwed on.

The invention will improve the reliability of its protection against falsification of the contents of the bottle that is sealed with this cap, as well as increase the reliability of its repeated closure.
