Description

Bottle neck and method for capping bottles

Technical field

The invention relates to containers, in particular, to the design of neck closures for bottles, made with the function of not only reliable sealing, but also to demonstrate the integrity of the shutter. The invention also relates to a method for corking bottles with such a neck closure in distilleries.

BACKGROUND OF THE INVENTION A throat closure is known, comprising a body installed in the neck of a container, made with a drain hole and in the inner cavity of which a valve is freely positioned so as to separate the cavity of the container and the cavity of the drain hole of the body when the container is upright and to communicate with these cavities when the container is empty, said valve made with a tapered landing surface and with blades to ensure fluid swirl when emptying the tank, made on the valve not on the side of the cavity of the container and / or cavity of the housing, but on the wall of the drain hole of the housing, on the side of the latter opposite to the location of the valve, blades are made for additional swirling of the swirling flow of liquid drained from the tank (RU N ° 22311487).

Known lid-stopper with a tear-off element, characterized in that the lid is made in the form of a cup equipped with a cap (made cylindrical with a flat lid), and the tear-off element with a gripping lobe has an elastic inner flange in the lower part, while the lid with a tear-off element and a stopper made of polymeric material, the cap is made of metal, for example, steel, the outer perimeter of the cork has an annular flap elastic protrusion with the possibility of its interaction with the flanging of the cap (RU Na 2006102434, B65D41 / 00, published on 08.20.2007) . Adopted as a prototype for both declared objects. The disadvantage of this neck shutter is its weak operational reliability.

A method of capping bottles is known from the same source, which consists in applying pressure to the bottle neck with the correct 5 oriented end of the stopper in the direction of deposition of the stopper on the neck, during which the polymer material of the cap of the stopper is stretched and then returns to its original state, providing a tight girth the corolla of the neck due to the elastic qualities of the cork material. ιо The disadvantage of this method is the design of the cork itself, which is made of a material that quickly loses its elastic properties when passing through the neck rim due to excessive stretching of the material. In practice, the cork sits on the neck, being held by friction, which leads to a large exit of marriage due to the unsuccessful landing of the cork on

15 neck (rupture of the skirt of the tube body, excessive stretching, leading to free rotation of the tube). Such phenomena arise due to the need to combine two different tasks in the cork: maintaining a tight neck coverage due to the low elasticity of the material walls and providing the possibility of cork settling on the neck due to

20 increased elasticity of the material of the skirt tube. To be able to simultaneously solve these two opposite problems, the tube skirt has to be cylindrical.

SUMMARY OF THE INVENTION The present invention is directed to solving the technical problem of

25 creating a cork of a reliable design for sealing and holding it on the neck of a bottle with elements of demonstration of factory capping. Part of the method solves the problem of reliable and guaranteed capping due to the separation of mutually opposite functions in the cork into its various parts. The achieved technical result is to increase the operational reliability of the use of the shutter simplification of the design and simplification of the method of corking while providing a high percentage of the output of a conditional capping product.

The specified technical result for the device is achieved by the fact that 5 in the neck closure for a bottle containing a stopper made of a polymeric material having an outer cylindrical wall to cover the neck of the bottle, a metal cap covering the stopper on the side of the end face of the stopper, and a tear-off element in the form of a tape with a gripping tab on a cylindrical wall, a metal lid in the form of a cup ιо is made with internal flanging, and on the outer surface of the cork from the end side, an annular hook is made for abutment against the wall of the roof ki during its landing on the tube and abut the end part of the stopper, wherein the detachable element in the form of a tape is formed integrally with the cylindrical tube wall and is a continuation of the wall of its height, cylindrical

15 the wall at a level below the location of the tear-off element ribbon is made with a hook to cover the rim of the bottle, and the end wall of the cork is made mushroom-shaped to accommodate the mushroom-shaped part in the neck of the bottle.

The specified technical result for the method is achieved by the fact that in

20 method of capping bottles on an automatic line, which consists in feeding the bottle neck with the correctly oriented end of the stopper and applying pressure to it in the direction of the neck to deposit the stopper on the neck of the bottle neck, the stopper is fed along the inclined surface of the orienter chute in the direction of the neck of the bottle with

In the direction of movement along the conveyor of the bottle of the part of the narrowed annular lower edge of the cork body at the outlet of the estrus below the rim of the bottle neck and at the moment of stopping the bottle neck moving along the conveyor to the inner edge of the narrowed annular lower edge of the cork, the cork is pressed in the direction of the bottle neck to upset the case plugs on the corolla of the neck of the plug and the placement of the narrowed annular lower edge of the plug body at or below the rim of the neck of the bottle, then, in the direction of the axis of the bottle, first press the metal cap of the cork until it is displaced into the end of the casing and then press the cap to move the casing until the mushroom-shaped element of the cork has an outer diameter larger than the inner diameter the diameter of the neck of the bottle, into the neck of the bottle and the stop of the rim of the neck of the bottle at the end of the casing body from the side of the metal cap.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The best embodiment of the invention

According to the present invention, the construction of a neck closure for a bottle with a neck, designed to reliably seal and demonstrate the integrity of the closure, is considered.

The neck closure for a bottle contains a stopper made of a polymer material having an outer cylindrical wall to cover the neck of the bottle, a metal cap covering the stopper on the side of the end face of the stopper, and a tear-off element in the form of a tape with a gripping tab on a cylindrical wall. Glass-shaped metal lid made with internal flanging, and on the outer surface of the cork from the end side, an annular hook is made for abutting against the wall of the lid when it fits on the cork and abutting against the end part of the cork. The tear-off element in the form of a tape is made integral with the cylindrical wall of the cork and is a continuation of this wall along its height, the cylindrical wall at a level below the location of the tape of the tear-off element is hooked to cover the rim of the bottle, and the end wall of the cork is made mushroom-shaped to accommodate the mushroom-shaped part in the neck bottles. The following is a specific example of shutter performance.

The shutter consists of two parts: a stopper 1 (Fig. 1, 3-6) made of polymer grades of medium density polyethylene allowed for contact with food products, and a cover 2 (Fig. 2) made of white metal tin plate with a thickness of 0.15 mm) . The cork is a one-piece polymer product, which can conditionally be divided by perforation 3 into two parts:

The upper one is a polymer plug in the form of a hollow body, which has a diameter 4 hook for fitting a metal cover 2 (fi 1), which is made in the shape of a polymer cilia. On the inside, the casing is made in the form of a hollow mushroom-shaped cork with a double wall 5, which allows tightly corking the neck of the bottle (while the elasticity of the material used and the design of the double wall allow springing of the contact between the outer wall of the cork and the inner wall of the neck of the bottle) .An external metal cap does not allows you to deform a hollow mushroom plug due to bearing in the thrust pad 6, which is adjacent to the metal cover.

The lower one is a tear-off tape 7 having vertical ribs-hooks 8 from the inner side from a horizontal displacement horizontal in diameter relative to the neck of the bottle. To protect against vertical displacement along the diameter of the tear tape, an annular hook 9 is located in its lower part, which, when corked, is tucked and hooked onto the ring whisk bottle. The design (geometry) is designed in such a way as to ensure automatic bottle corking using standard orienting and capping equipment of the plants. The tear-off tape has an extended tail 10 for ease of tearing. The cover 2 is a stamped metal part of a glass-like shape made of white food sheet with a thickness of 0.15 mm, a diameter of 6.3 mm and a height of 5.8 mm, which has a special hook on the inside in the form of iodorot 11 1.15 mm high.

The functional purpose of the cap: - provides a rigid fit of the polymer part on the neck of the bottle;

- protects the plastic part (cork) from mechanical damage (penetration to the contents of the bottle)

- is a decorative element (applying a logo, painting, etc.).

The corking process with the cork in question can be implemented on the well-known automatic lines used by JIB 3, which does not require large expenses for the adjustment of capping equipment. The method of capping bottles with such stoppers on an automatic line is to feed the bottle neck with the correctly oriented end of the stopper and apply pressure to it in the direction of the neck to deposit the stopper on the neck of the bottle. The cork is fed along the inclined surface of the orientator estrus in the direction of the neck of the bottle with the portion in the direction of movement along the conveyor of the bottle of the narrowed annular lower edge of the cork body at the outlet of the estrus below the rim of the neck of the bottle and, at the moment of stop, the bottle neck moving along the conveyor into the inner edge of the narrowed annular lower edge the casing body tightens the cork in the direction of the neck of the bottle to upset the casing of the cork on the rim of the neck of the cork and place a narrower ring howl the lower edge of the casing body at or below the level of the rim of the neck of the bottle, then, in the direction of the axis of the bottle, first press the metal cap of the cork until it is displaced into the end of the cork body and, with further pressure on the cap, move the casing until the mushroom-like element of the cork body having an outer diameter penetrates larger than the inner diameter of the neck of the bottle into the neck of the bottle and the stop of the rim of the neck of the bottle at the end of the cork body on the side of the metal cap.

In more detail, this method is explained in detail below. On production lines, the process of orientation of the plugs on any of the well-known industrial orientators of the jaw or vibration type is first carried out and along the estrus, the plug is sent to the plug fitting unit on the top of the bottle rim.

Due to the tilt (about 30 degrees) of estrus exit to the surface of the conveyor along which the bottle is fed, and with the help of a spring-loaded foot, the rim of the supplied bottle hooks with its forward movement over the edge of the hollow part of the cork - ring hook (flanging). And with translational movement, the spring-loaded foot upsets (cork) on the rim of the bottle to the depth of the first corolla. Located at an angle inward, the annular hook of the plug firmly holds the plug on the upper part of the whisk and at the same time centers the fit in diameter.

Next, the bottle with the pre-fitted stopper moves along the conveyor to the press-in unit (capping head). In the process of pressing on the corolla, the pressure of the capping head is on the metal cover, which in turn rests on the supporting platform of the polymer part of the cork. In the process of pressing, the mushroom-shaped element, having an outer diameter larger than the inner diameter of the bottle neck, is compressed as a result of which the upper end part of the stopper abuts against the inner end surface of the metal cap - this allows significant force to be used when corking without damaging effects on the cork.

The tear tape elements do not experience critical loads, as forces are distributed to a greater extent on the end part of the cork, and only a small (insignificant) part of these forces is distributed along the 5 circumference of the end of the tear tape.

When pressing, due to the onward inclination of the lower flanging element of the cork - the ring hook and the rim of the bottle, the ring hook of the cork is tucked and automatically latches onto the first corolla. ιо Further, when releasing the pressing force, the mushroom-shaped element rests against the metal cover and springs it with its support pad due to the force vector directed upward from the compression force.

Opening is carried out by the extended tail counterclockwise. Interplay of vertical cork hooks

15 and the whisk of the bottle do not allow the tear tape to radially shift. And when the force is applied, the weakening element of the flanging is broken and then the place of weakening at the place of perforation of the tear-off tape is broken. Thus, the autopsy is controlled.

When attempting unauthorized access to content

20 bottles - removing the cork is only possible in the upward direction. The annular hook of the cork is in the folded position and is hooked on the first ring of the whisk of the bottle. Upward movement is not possible without destroying the weakening of the tear tape, which allows visual inspection of the opening.

25 Cork 1 is inserted into the neck of the bottle so that its inner hollow mushroom-shaped part abuts against the inner wall of the neck of the bottle. When a metal cap is put on top, it crushes the cilia of the hook 4 and abuts against the thrust pad 6. When the lid is removed, the cilia are damaged, and when the cork is removed, the tape 7 breaks and the hook 9 deforms, which indicates a previous action to open the bottle. Since capping is carried out automatically mode, the shutter integrity indicates factory corking and product authenticity.

Industrial applicability

The present invention is industrially applicable and can be manufactured using the technologies used for the manufacture of polymer valves. And it is applied on capping lines used at distilleries almost without alteration of the latter
