Description

BOTTLE CLOSURE (EMBODIMENTS)

This invention relates in general to bottle closures used for bottling and storing alcohol products.

Known is a closure including a tubular body and an inner hood with a threaded exterior side surface, made integrally, a cap having a thread on its interior side surface and an annular projection on its interior end surface, which is made to accommodate the hood, said cap having a protective ring at the lower end, said protective ring being fixed on the cap by means of a weak section to form a break-off tamper-indicating member, which has one or more longitudinal cuts (RU JN° 2004118523, B65 D 39/00, of 21.06.2004).

The disadvantage of the known closure is that it is non-standard and can not be used in up-to-date bottling and closing factory lines, as these lines are designed to use taller «Guala» closures. To rebuild the process line requires great expenditures and higher product costs. Besides, there will be no reliable closing, compact flow, and accurate liquid measuring.

The proposed invention eliminates the aforesaid disadvantages through improvements in closure design making it possible to use closures with the standard equipment, to enhance the reliability of closing, to find out any unauthorized opening of the bottle, to reduce the risk of the bottle being refilled with low quality spirits, and to allow accurate liquid measuring.

The aforesaid technical result is achieved in that the closure includes a hood with a skirt and a threaded exterior side surface, a cap with a threaded interior side surface, an annular projection and a coaxial annular projection located on the interior end surface. The annular projection is made to accommodate the hood.

The hood contains a removable gate. The upper end of the hood is located between the side surface of the cap and the coaxial annular projection.

33MeHWOPiI JincT The removable gate consists of a tubular body and an inner hood, made integrally, with evenly spaced windows on the side wall, said windows being covered with the annular projection of the cap. The removable gate has an outer flange with a collar on its surface to be fixed in the hood. The tubular body is made to be inserted into the bottleneck.

There are sealing lips on the exterior surfaces of the tubular body and the collar of the removable gate. There are longitudinal stiffening ribs on the interior surface of the collar, which are spaced evenly around the periphery of the surface.

On the interior side surface of the skirt, there are longitudinal stiffening ribs and a lock with a tapered interior surface designed to lock the bottleneck collar. The lock has longitudinal cuts. The lock can be made in the form of inward projections, separated or arranged in groups.

There are ribs on the exterior side surface of the hood and the interior side surface of the cap, near their lower end, to form a joint.

The end of the skirt is perpendicular to the longitudinal axis of the closure in the area of the abutment between the skirt and the cap's end. -

The exterior side surface of the cap has knurling on it. A gasket can be placed in the annular gap between the tubular body of the removable gate and the interior side surface of the skirt.

Such a closure can be made with a protective ring fixed on the cap near its lower end by means of a weak section in order to form a break-off tamper- indicating member, which has one or more longitudinal cuts (embodiment 2), or with a valve (embodiment 3), or with a protective ring and a valve (embodiment

4).

Providing a coaxial annular projection on the interior end surface of the cap between the side wall of the cap and the annular projection, providing a removable gate in the hood, and the placement of the upper end of the hood between the side wall of the cap and its coaxial annular projection makes the closure taller. These improvements in closure design makes it possible to use closures with the standard industrial equipment.

SaMeHRK)IJUlMM JlMCT Besides, the presence of the removable gate with a tubular body and the inner hood, said inner hood having evenly spaced windows on its side wall, and the presence of the exterior flange with a collar, ensures a reliable fixing of the removable gate in the hood, makes the closure to fit tightly to the bottleneck collar, and, consequently, results in an increase in the reliability of bottle closing and the accuracy of measuring the flowing liquid.

Covering the windows with the annular projection of the cap eliminates the possibility of liquid evaporation from the stored bottle. The presence of the sealing lips on the exterior surface of the tubular body and the collar makes the closure tight.

The presence of the lock and longitudinal ribs on the interior surface of the skirt makes the closure to fit tightly to the bottleneck collar. That makes pulling the closure off the bottle difficult and ensures reliable closing.

Placing the end of the skirt perpendicular to the longitudinal axis of the closure in the area of the abutment between the skirt and the cap's end ensures their tight contact, makes an unauthorized opening of the bottle difficult, and provides an effective protection.

The presence of a protective ring fixed on the cap near its lower end by means of a weak section in order to form a break-off member, which has one or more longitudinal cuts makes it possible to reliably indicate an unauthorized opening of the bottle.

Equipping the removable gate with a vale results in an increase in the reliability of the bottle closing and reduces the risk of the bottle being refilled with low quality spirits.

The other parts described in the subclaims facilitate achieving the claimed technical result.

The proposed invention will now be explained by way of the non-limiting description of the preferred embodiments and with the reference to the accompanying drawings in which:

Figure 1 is a view of the section of the closure;

Figure. 2 is a view of the tubular body and the inner hood;

Figure 4 is a view of the cap without the protective ring (embodiment 1);

Figure 5 is a view of the cap with the protective ring (embodiment 2);

Figure 6 is a view of the closure with the valve (embodiment 3);

Figure 7 is a view of the closure with the protective ring and the valve (embodiment 4);

Figure 8 demonstrates the embodiments of the weak section between the protective ring and the cap.

In embodiment 1 , the closure includes a hood 1 which has a cylindrical skirt 2 and a thread 3 on its exterior side surface, a cap 4 which has a thread 5 on its interior side surface, an annular projection 6 and a coaxial annular projection 7 on its interior end surface.

There is a removable gate 8 within the hood 1 , which is made as a tubular body 9 containing sealing lips 10, an inner hood 11 with the closed upper end 12 and windows 13 on its side wall, an external flange 14 and a collar 15 with sealing lips 16 and longitudinal ribs 17.

The skirt 2 has longitudinal ribs 18 and a lock 19 with a tapered interior surface 20. The upper end 21 of the hood 1 is located between the interior side surface of the cap 4 and the coaxial annular projection 7. The lock 19 has longitudinal cuts 22. The lock can be made in the form of inward projections 23, separated or arranged in groups.

The hood 1 and the cap 4 have, accordingly, ribs 24 and 25 to form a joint.

The exterior side surface of the cap 4 has knurling 26 on it.

A gasket 27 can be placed between the interior side surface of the skirt 2 and the tubular body 9.

In embodiment 2, the cap 4 has at its lower end 28 a protective ring 29 with one or more longitudinal cuts 30. The protective ring is fixed on the cap 4 by means of a weak section made in the form of notches 31, or perforations 32, or a breakable strip 33 (see. Fig. 8).

In embodiment 3, the removable gate 8 has a valve 34. In embodiment 4, the cap has a protective ring 29, and the removable gate 8 has a valve 34.

3aMeHaκ)iiWM JIMCT The proposed closure will be assembled and used as follows.

In embodiment 1 , the removable gate 8 and the gasket 27, if necessary, will be inserted in the hood 1. Then the cap 4 will be screwed hard on the hood 1. The whole assembly is then set on the bottleneck (not shown in the Fig.) using some force. In the process, the tubular body 9 enters the bottleneck, the lock 19 with the tapered surface 20 expands due to several longitudinal cuts 22 to give way to the bottleneck collar, and goes back after the passing of the bottleneck collar. The longitudinal ribs 18 ensure the closure is fixed on the bottleneck.

As the cap 4 is being screwed on the hood 1, the ribs 24 and 25 become engaged to form a joint, which makes unscrewing difficult.

In embodiment 2, the cap 4 is fabricated 4 with a weak section, which forms a protective ring 29. The weak section is prepared beforehand by means of notches 31 on the interior side of the cap, or perforations 32, or the breakable strip 33. As the cap 4 is being unscrewed, its lower part separates along the weak section, the protective ring 28 opens wide if there is one longitudinal cut 30, or breaks into pieces if there is a number of cuts.

In embodiment 3, a valve 34 is inserted into the removable gate 8, to be followed by all the steps according to embodiment 1.

In embodiment 4, the closure is equipped with a protective ring 29 and a valve 34. The assembling procedure is the same as in embodiment 1.

The use of the proposed inventions ensures the necessary technical result due to improvements in the closure design.
