Description

The utility model relates to the food industry and relates to closures for glass bottles intended, for example, for bottling and storing alcoholic beverages in them.

Corking devices are widely known and used in the vodka industry.

A number of sealing devices for bottles are described, for example, in the declarative patents of Ukraine for utility model No. 21374, IPC: B65D 41/34, publ. 06/15/2006; No. 16890, IPC: B65D 41/34, publ. 08/15/2006; they contain a cylindrical body, which is put on with force on the neck of the bottle, and in order to avoid turning the body of the device relative to the bottle when opening its internal longitudinal protrusions engage with the protrusions on the outer surface of the neck of the bottle.

The closest analogue of the claimed technical solution is a plugging device protected by Ukrainian patent No. 61346, IPC: B65D 41/34, publ. 07/11/2011. Said sealing device comprises a plastic cylindrical body with a decorative casing, a lid fixed therein, which has an internal thread aligned with the external thread of the dispensing device, as well as a sealing sleeve, the upper seating surface of which is aligned with the pouring element, and the lower seating surface with ensuring tightness it is coordinated with a mouth of a bottle. In order to avoid scrolling the dispensing device relative to the bottle when opening the closure device by unscrewing the housing, the closure device contains safety elements: the stopper between the upper and lower seating surfaces has an annular protrusion, on the lower supporting annular surface of which fixing hooks are made, the number and placement of which are agreed with protrusions on the end surface of the neck of the bottle, and on the upper supporting annular surface are fixed guides prongs which in the assembled state of the closure device are in engagement with locking elements seeder device.

When installing such a closure device on a bottle, the locking elements at the bottom of the dispensing device engage with an annular protrusion at the top of the neck of the bottle, thereby locking the closure device on the bottle in the axial direction. In this case, the protrusions on the end surface of the neck of the bottle are pressed with force into the depressions between the locking hooks, thus providing rotational fixation of the closure device.

Due to this, when opening the closure device by applying rotational force to its body, the dispenser is stationary in relation to the bottle neck and the case can be unscrewed relative to the dispensing element.

The disadvantage of such a clogging device is the certain complexity of the structural element - the sealing of the bushings as well, and, as a result, the lack of reliability: as the practical application of such clogging devices has shown, sometimes opening requires considerable effort, and sometimes it is completely impossible, especially in case of an incorrect initial screwing (instead of unscrewing) the housing. This is due to the fact that the transmission of rotational force during unscrewing is carried out along the following chain: arm - housing - cap - threaded connection between the cap and the dispensing device - hook connection between the dispensing device and the sealing sleeve - hook connection between the sealing sleeve and the neck of the bottle neck. To ensure a tight connection between the dispenser, usually made of relatively hard polystyrene, and the neck of the glass bottle, the sealing sleeve is made of flexible polyethylene. As a result of technological and assembly scatter, as well as under the influence of storage conditions for a filled bottle (heat / cold), the force required to overcome friction in the threaded joint when opening can be different and reach values at which the elements of the polyethylene plug that provide rotational fixation, may be damaged by harder fixing elements of the dispenser and / or bottle. Such damage can also occur in the case of an erroneous rotation of the casing of the plugging device in the wrong direction, which requires even greater efforts, and therefore these fixing elements are deformed completely - opening the bottle becomes impossible.

The utility model is based on the task of increasing the reliability of the clogging device of the aforementioned type by performing elements for transmitting forces from a solid material, as well as simplifying the design.

This problem is solved in that in the closure device for a bottle of liquid, which contains a plastic cylindrical body equipped with a casing with a control detachable ring made in the lower part, a lid that is fixedly fixed in the body, which has an internal thread aligned with the external thread of the pouring element, and a sealing sleeve, the upper landing part of which, with ensuring the tightness, is coordinated with the pouring element, and the lower landing part, with ensuring the tightness, is coordinated and with the neck of the bottle, and the closure device has rotational fixation elements of the closure relative to the bottle, on the end surface of the neck of which locking projections are made, according to a utility model, the rotational fixation elements are made on the annular supporting surface of the pouring element in the form of teeth, the number and placement of which are aligned with the protrusions on the end surface of the neck of the bottle. Due to this technical solution, when opening the closure device, the force from the pouring element is transmitted directly to the protrusions of the neck of the bottle, that is, the sealing sleeve is removed from the force transmission circuit - a structural element made of soft material and designed to ensure tightness. This increases the reliability of the clogging device.

According to a utility model, the sealing sleeve itself has an annular protrusion between the upper landing part and the lower landing part, the upper and lower supporting surfaces of which are made flat. With these abutment surfaces, the sealing sleeve is clamped between the pouring element and the end surface of the bottle neck, increasing the sealing reliability.

In addition, the control tear-off ring has at least two transverse sections. Due to their presence, the ring breaks up into two halves during the first opening of the plugging device, clearly confirming that the first opening is taking place.

The utility model is explained in more detail below using the drawings. They schematically depict:

6 Sealing sleeve in longitudinal section.

The closure device for a liquid bottle shown in FIG. 1 comprises a plastic housing 1, a cover 2, a pouring element 3, and a sealing sleeve 4.

The housing 1 is equipped with a decorative casing 5, fixedly mounted, for example, glued to the outer surface of the housing 1. In the lower part of the housing 1, by introducing sections of weakened strength, a control tear ring 6 is formed.

The cover 2 is fixedly mounted inside the housing 1, for example due to the connection with a geometric circuit. A thread is made on the inner side surface of the cover 2, and a vertical annular protrusion 7 is formed on its inner end surface.

On the outer surface of the upper part of the pouring element 3, a thread 8 is made, matched with the thread of the cover 2.

In the lower part of the pouring element 3 made locking hooks 9.

On the lower supporting annular surface 10 of the pouring element 3, fixing protrusions 11 are made, mainly in the form of teeth, the dimensions and placement of which are consistent with the size and placement of the protrusions 12 on the end surface of the neck of the bottle (figa, b).

The tightness of the connection between the inner cavity of the bottle and the pouring element 3 is provided by the sealing sleeve 4. The sealing sleeve 4 has an upper seating portion 13 and a lower seating portion 14 connected by a horizontal annular protrusion 15, the upper supporting surface 16 of which and the lower supporting surface 17 of which are made flat.

When assembling the sealing device, the cover 2 is screwed onto the pouring element 3. In this case, the annular protrusion 7 of the cover is hermetically adjacent to the inner surface 18 of the outlet of the pouring element 3.

The sealing sleeve 4 is inserted from below into the inlet 20 of the pouring element 3. In this case, the upper seating portion 13 of the sealing sleeve 4 with the sealing rings 19 fits snugly against the inner surface of the inlet 20 of the pouring element 3, and the upper abutment surface 16 fits snugly against the flat portion of the lower support annular surface 10 of the pouring element 3.

The formed intermediate assembly with force is inserted into the housing 1. At the same time, the protrusions on the inner surface of the housing 1 engage with grooves on the outer surface of the cover 2, ensuring their mutual rotational fixation, and the lower edge 21 of the cover 2 pops up behind the annular protrusion 22 on the inner surface housing 1, ensuring their mutual axial fixation. At the same time, the inner protrusion 23 of the tear-off ring 6 of the housing 1 pops up behind the lower edge 24 of the pouring element 3. Then, with fixing with glue, the housing 1 is inserted into the decorative casing.

When fitting the closure device to the bottle, the lower landing portion 14 of the sealing sleeve 4 enters the neck of the bottle and the sealing rings 25 fit snugly against the inner surface of the neck of the bottle. In this case, the flat lower supporting surface 17 of the sealing sleeve 4 is pressed by the pouring element 3 and fits snugly against the flat part of the end surface of the neck of the bottle, increasing the reliability of the tight connection between the bottle and the sealing sleeve 4.

The axial fixation of the closure device on the bottle is provided by the locking hooks 9, which, when the closure device is mounted on the bottle, pops up behind the annular protrusion 26 on the outer surface of the neck of the bottle (Fig.2b).

The rotational fixation of the closure device on the bottle is provided by the locking protrusions 11 of the pouring element 3 due to the fact that each of the protrusions 12 on the end surface of the neck of the bottle is clamped between the two locking protrusions 11 of the pouring element 3.

When the closure device is first opened by rotating the housing 1 relative to the bottle, its rotational movement due to the threaded connection between the cap 2 and the pouring element 3 turns into the translational movement of the housing 1 together with the cap 2. In this case, the lower edge 24 of the pouring element 3 presses on the inner protrusion 23 of the tear-off ring 6 of the housing 1 and, overcoming the resistance of places of weakened strength, tears off the ring 6 from the housing 1. Due to the presence of two transverse cuts, the ring 6 splits into two parts. In this way, the first bottle is opened. With the subsequent unscrewing of the housing 1, the annular protrusion 7 of the lid comes out of contact with the inner surface 18 of the pouring hole, opening the way for pouring the contents of the bottle.

Closing a bottle that has not been emptied is carried out by screwing the housing 1 with the lid 2 onto the pouring element 3 until it stops.

Due to the fact that, according to a useful model, the elements of the rotational fixation of the closure device on the bottle are made in a pouring element made of a relatively solid material, mainly polystyrene, high reliability of the rotational fixation is achieved in a wide range of possible forces required to unscrew the housing 1 with the cap 2.
