Description

(54) CLOSURE DEVICE FOR DRAINING LIQUID FROM A CYLINDER BOTTLE

Field of technology

The utility model relates to the construction of screw-based closures which are equipped with devices for pouring liquid in random doses and capturing droplets, while allowing repeated opening and closing of the bottles. With such devices it is advisable to equip bottles for expensive spirits (especially for liqueurs), mainly for edible oils, sauces, syrups, etc., in order to prevent the leakage of the metered liquid on the outer surface of the bottles.

BACKGROUND OF THE INVENTION

It is well known that for pouring a dose of liquid into a bottle closed with any ordinary, ie. insert or removable (particularly screw) stopper, the bottle is opened and tilted, and to stop the liquid from pouring out of the bottle, it is again raised to a vertical position. Under such conditions, during the delivery of each successive dose of liquid, part of it flows on the outer surface of the neck of the bottle. This always leads to irreversible loss of liquid, which is greater the larger the volume of the bottle and the smaller the individual doses, and also (especially when pouring viscous liquids), and to contamination of the outer surface of the bottle.

Some means of combating these side effects are already known.

In particular, the basis of these means can be a manually operated volumetric dosing pump, which has a housing with a measuring chamber, an inlet channel for its periodic connection to the source of dosing liquid, an outlet channel for emptying the measuring chamber, an ejector of the measured dose from the measuring chamber. a chamber in the exhaust duct, and at least one means for separating the measuring chamber from the source of liquid during its emptying (see Great Encyclopedic Polytechnic Dictionary - M .: Scientific Publishing House "Great Russian Encyclopedia", 1998, p. 341).

An example of the use of the described dosing pump for emptying bottles is the volume dispenser for liquids of the company ZIEHER (Germany), which has:

ossymmetrical in the upper part hollow body with a measuring chamber with a fixed volume, which is made of liquid-inert (usually polymeric) material, a fixator in the form of a movable, tightly connected to the body stopper, which covers the neck of the bottle, closes its opening and there is a curved protrusion with an outlet channel for feeding the metered dose, a spherical ejector of the metered dose liquid, which is located inside the measuring chamber and in the initial position is below the level of the inlet channel in the side wall of the lower part of the chamber located in the lower part. on the housing along the measuring chamber, an exhaust channel which closes when a dose is delivered by the ball valve separator, a through-hole in the air permeation retainer inside the bottle during the supply of the metered dose.

The volumetric dispenser is mounted on a vertically standing, open bottle instead of the removed factory stopper in such a way that the curved protrusion with the exhaust channel remains outside the radial size / size of the bottle. Therefore, the last drops of dosing liquid left in the exhaust duct cannot contaminate the outside of the bottle.

However, the described (and any other similar) volumetric dispenser is a rather complex (and therefore expensive) stand-alone product that is placed on the neck of the bottle instead of the removed factory cap and therefore it is impossible to place it on production lines for filling bottles with liquid. , nor its use for repeated closing and opening of bottles. In addition, each subsequent use of the described dispenser to prevent losses of the dosing liquid, it is necessary to wait a long time until its last drops flow from the said protrusion into the respective vessel (eg wine glass, brandy, frying pan, etc.) . Finally, volumetric dispensers are designed to measure the same doses of liquid, which in most cases, when bottling beverages and other food liquids, is practically not needed.

It is therefore desirable to use such closures which are provided with devices for dispensing the liquid in random doses with trapping of the drops and allow repeated opening and closing of the bottles (see US 2773632; WO 1990/008074; US 6112949; WO 2003/068621 and many others).

Among them, the closest analogue of the utility model is the closing device described in UA 97539. This known device has:

a screw stopper with a firmly fixed sealing pad which is oriented in working position, inside the neck of the bottle, a cylindrical central protrusion with at least one longitudinal slot / slot on its outer side wall and an annular support threshold covering the upper part of this protrusion with an annular gap placed in the neck of the bottle device for pouring liquid in random doses with trapping drops, which includes:

- a sleeve / sleeve with a liquid inlet at the bottom and a thread on the inside of the wall, which in the working position is tightened in the neck of the bottle,

- movable relative to the sleeve, an exhaust pipe diverter (spout) which has a lower threaded part corresponding to the thread of the sleeve and providing the possibility of axial reciprocating movement of the pipe diverter (spout), and an upper part in the form of a flexible funnel, which is connected kinematically by a radial tooth to said channel / slot of the above-mentioned central protrusion, in the initial position it is clamped between this protrusion and the annular support threshold of the sealing pad, and in the operating position it serves as a droplet trap.

When unscrewing the plug, the kinematic pair "longitudinal slot - tooth" forces the pipe diverter (spout) to rotate and unscrew from the sleeve. Since the axial size of the threaded connection of the pipe diverter with the sleeve exceeds the axial displacement of the plug at the moment of exit of the sealing pad from the contact with the pipe diverter (spout), the lower part of the diverter does not protrude beyond the sleeve. After removing the stopper, said funnel-shaped widening is opened to drain the dose of liquid. In this case, the last drops of each successive dose of liquid, according to the known inventive concept, must flow inside the bottle before it is placed in a vertical position. If it is necessary to close the bottle again, the process is performed in reverse order. In addition, said tooth must be inserted into said longitudinal slot.

Unfortunately, the known closing device has an extremely complex construction and is therefore inconvenient to manufacture and use. In particular, the use of a screw connection of the movable tubular diverter (spout) with the fixed sleeve significantly complicates the manufacture of these parts as such, as well as the pre-assembly of devices for pouring liquids at random doses and their installation in the bottle necks. In addition, the use of the kinematic pair "longitudinal slot - tooth" requires a lot of time to connect them each time the bottle is closed.

Technical essence of the utility model

At the heart of the utility model is the task, by improving the geometric shapes of the parts, to create a significantly simpler in design and convenient to manufacture and use closure device suitable for pouring liquid from a bottle in arbitrary doses.

This problem is solved by the fact that in the closure device suitable for pouring liquid from a bottle in random doses and including a screw stopper with a firmly fixed sealing pad, which has a cylindrical central protrusion oriented in the working position in the neck of the bottle, and a device for dispensing liquid in random doses by capturing the droplets, which has a sleeve which has at least one inlet for liquid in its lower part and in the working position is placed with a clamp in the neck of the bottle and a tubular diverter (spout) movable relative to the sleeve, which is kinematically connected to the above-mentioned central protrusion of said sealing pad to provide axial reciprocating motion, the upper part of which, in the working position, serves to catch

2667 UI wire drops,

According to the utility model, said movable tubular deflector (spout) and cylindrical central protrusion of the sealing pad in the plug are kinematically connected at the initial position with at least one tooth suitable for flexible attachment and detachment of said parts, and said sleeve and movable tubular deflector ) are provided with radial abutment stops of the axial displacement of this deflector.

Such a closing device, compared to the prototype, is much simpler in design and more convenient to manufacture, assemble and operate. Indeed:

most of the details of the device can be made by high-performance injection molding and joined together by assembling with light pressure, according to the inventive concept, all devices for pouring liquid at random doses are mounting units that are possible in advance to be connected to the screw plugs for further placement of the whole closing devices in the necks of bottles on standard filling-closing lines, the kinematic connection of the movable pipe diverter (spout) and the central protrusion of the sealing pad in the stopper with at least one prong off during the next closing of the cylinder, the need to choose the necessary mutual arrangement of the parts for adhesion, the radial supports-limiters of the axial movement of the movable pipe diverter (spout) relative to the sleeve, practically exclude accidental dropping of the pipe diverter (spout) from the sleeve at the next opening of the bottle and the possibility to axis melting open.

The first and second additional differences consist in the fact that the sleeve is closed on the underside and at least one inlet for discharging liquid is made in the lower part of the side wall of the sleeve, and / or the movable pipe diverter (spout) is partially closed in its lower part, and at least one liquid inlet is made in the side wall of the pipe diverter (spout). All this ensures a smooth flow of liquid and reduces the likelihood of hydraulic shock when the bottle is tilted sharply.

The third additional difference is that the upper part of the movable pipe diverter (spout) has a funnel shape. This makes it easier to catch the last drops when you stop pouring liquid.

The fourth additional difference is that the sleeve is clamped in the neck of the bottle using at least one annular radially oriented protrusion. This simplifies the fluid placement of the liquid dispensers at random doses into the bottle necks.

Explanation of the attached figures

The essence of the utility model is further explained by a detailed description of examples of the construction of the proposed device and the way of its use, with reference to the attached drawings, where they are depicted in: figure 1 - closing device in initial position in the bottle neck (longitudinal section with a vertical plane that includes the axis of symmetry);

Figure 2 - closing device in working position (also a longitudinal section with a vertical plane, which includes the axis of symmetry).

Examples of implementation of the utility model

The closure device suitable for pouring liquid from a bottle in random doses according to FIG. 1 has a screw plug 1 with a sealing pad 2, which has a cylindrical central protrusion 3 oriented in an operating position inwards in the neck 4 of the bottle and a device for pouring the liquid in random doses by capturing the drops. The device includes:

a sleeve 5 having at least one unlabeled opening for discharging liquid in the lower part and which in the working position is clamped in the neck 4 of the bottle, movable relative to the sleeve 5 a tubular diverter (spout) 6 which is kinematically connected to the above-mentioned central protrusion 3 of the sealing pad 2 to provide the axial reciprocating movement, the upper part of which, in the working position, serves as a droplet trap.

2667 UI

The movable tubular diverter (spout) 6 and the cylindrical central protrusion 3 are kinematically connected in the initial position with at least one tooth 7, suitable for flexible attachment and detachment of said parts. It is clear to the person skilled in the art that it is expedient to use two (even better three) located at equal angular distances teeth 7 and that they can be located either on the central protrusion 3 (as shown in particular in FIG. 1), or the pipe diverter (spout) 6.

The sleeve 5 and the pipe diverter (spout) 6 must be provided with radial abutment stops 8 of the axial movement of the pipe diverter (spout) 6. It is clear that the distance between these abutment stops 8 sets the maximum value of the permissible axial displacements of the pipe diverter ( spout) 6.

It is desirable for the sleeve 5 to be closed in its lower part, and the inlet for discharging liquid to be made in the lower part of the side wall of the sleeve 5, and / or the movable tubular diverter (spout) 6 to be partially closed in its lower part. , and in its side wall 6 to be made at least one, not marked hole for infusion of liquid.

It is expedient for the upper part of the tubular diverter (spout) 6 to be funnel-shaped and for the sleeve 5 to be clamped in the neck 4 of the bottle using at least one annular radially oriented protrusion 9.

It is clear that all parts of the device, except the screw plug 1, must be made of a material inert to the liquid that will be poured into the bottles. In particular, such materials may be thermoplastic polymers such as polyethylene, polypropylene, polyethylene terephthalate and the like.

The described device, which has two main mounting units (namely a screw plug 1 with a sealing pad 2 and a device for pouring liquid in random doses) is used as follows.

First, the liquid pouring devices are assembled at random doses, and then they are connected to the screw plug 1 with teeth 7. The closing devices thus obtained are fed to a standard flow filling-closing line, where the pouring devices are placed. liquid in the necks 4 of the bottles and the screwing of the stoppers 1. Then the neck 4 of each bottle acquires the form shown in fig. 1.

If it is necessary to deliver a dose of liquid from the bottle, unscrew the stopper 1. In this case, the sealing pad 2 rotates around the axis of symmetry and pulls the tubular diverter (spout) 6, which protrudes upwards from the sleeve 5 until the radial stops 8 do not make contact and the tooth (or teeth) 7 are not released. As a result, the neck 4 of the bottle acquires the shape shown in FIG. 2.

In this form, the bottle is ready to pour another dose of liquid. Upon dispensing, the upper part of the tubular diverter (spout) 6 blocks the ingress of drops on the side surface of the bottle, and after stopping the pouring, ensures the flow of the last drops inside the bottle.

To close the bottle again, a stopper 1 with a sealing pad 2 is manually placed on the neck 2 and screwed, which leads to reconnection of the pipe diverter (spout) 6 with the pad 2 by means of teeth 7. Then the pipe diverter 6, under the influence of the sealing pad 2 returns to the lower position relative to the sleeve 2, as shown in FIG. 1.

The proposed devices for pouring a variety of liquid products in random doses can be mass-produced with the available equipment for processing thermoplastics and placed in the necks of random bottles using the available flow filling and closing lines.
