Description

Technical field

The utility model relates to the design of closures based on caps (or caps) with capsules for placement in the necks of predominantly polymer bottles of prize inserts such as instant winnings in the form of rolled up banknotes or paper messages about cash or clothing prizes that individual consumers may receive after uncorking bottles .

State of the art

The use of prize-winning bottle inserts to stimulate demand for beverages such as beer, mineral and fruit water and juices and nectars is now well known.

First, such inserts were placed under the gaskets on the bottoms of metal screw plugs. However, under such gaskets, only thin liners of inert drinks and unable to soak materials can be placed.

Therefore, paper prize inserts began to be placed under the polymer caps in capsules hermetically sealed in working position (http://www.slavutich.ua/akcia4.html).

Capsules are usually used as part of all caps (or corks) for closing bottles of those batches of drinks where there are separate prize inserts. Firstly, because otherwise it will be necessary to reconstruct the existing automatic production lines for bottle capping. Secondly, because carriers and sellers should not visually recognize bottles with prize inserts in the total mass of sealed bottles.

Accordingly, capsule caps should be cheap to manufacture, easy to assemble, and reliable to use after bottle capping.

A device for placing a prize insert in the neck of a bottle, which has a lid and a capsule in the form of a hollow (in particular, cylindrical) body of revolution, made in one piece with the bottom, is known from the Ukrainian patent No. 18028 for an industrial design made of a “food” thermoplastic polymer. Opened in the initial position, the upper end face of such a capsule is tightly connected to the bottle cap, namely, it is ultrasonically welded (or, less commonly, glued) to it. The outer diameter of the capsule over its entire height is smaller than the inner diameter of the neck of the bottle (especially when the capsule is equipped with an annular collar on the upper end to facilitate attachment to the cap).

Low-temperature ultrasonic welding virtually eliminates damage to paper liners during the connection of capsules with caps and protects them from wetting with beverages during transportation, storage and sale of sealed bottles.

However, devices for automatic ultrasonic welding of polymers are expensive and inconvenient to use, since the flow sealing of empty and “charged” capsules during the preparation of caps for installation in bottle necks is significantly complicated.

Therefore, it is advisable to use such devices to place prize inserts in the necks of the bottles, the parts of which (i.e., the cap and capsule) are connected purely mechanically.

From UA 54347 U, the closest in technical essence analogue of the device proposed below for the placement of the prize insert in the neck of the bottle is known. It consists of a lid that has a practically flat bottom and inside bottom and a screw skirt with a tear-off control ring, which, during the capping of the bottle, pops up behind the annular protrusion of the bottle neck, and a capsule clamped relative to the lid in the form of a hollow body of revolution, which is made in one piece with its own end bottom and has an open top in the initial position. For installation with an interference fit in the bottom of the cap, the capsule is equipped with an annular shoulder at the upper end, which has a thickness almost identical to the wall and bottom of the capsule and the outer diameter is larger than the inner diameter of the neck of the bottle. This collar in the working position is pinched between the said bottom of the cap and the end of the neck of the bottle. In addition, the capsule has an additional means of sealing, suitable for insertion into the neck of a bottle with an interference fit.

The known device provides a double mechanical seal of the cavity with a prize insert, first when assembling the cap with the capsule, and then when closing the bottle. Accordingly, there is no need for inconvenient, time-consuming and energy-intensive welding (or gluing) of the capsule to the bottom of the lid (or cork).

Unfortunately, in the short time that has elapsed since the creation of the utility model described above, the axial dimensions of the caps have substantially decreased to reduce material consumption, and therefore the use of capsules with ring collars, which serve as gaskets between the bottoms of the caps and the ends of the bottle necks, has become practically impossible. Indeed, even a slight decrease in the thickness of the said annular collar in comparison with the wall and bottom thickness of the capsule significantly reduces the rigidity and strength of the collar and increases the risk of depressurization of the cavity with the prize insert.

The essence of the utility model

Therefore, the utility model is based on the task of improving the geometric shape and friction relationship of the lid with the capsule to create such a device that is able to provide effective sealing of the prize insert against the background of a decrease in the axial dimension of the lid.

The problem is solved in that in the device for placing the prize insert in the neck of the bottle, having a cap, which consists of a practically flat bottom outside and a screw skirt with a tear-off control ring, and a capsule for the prize insert, which is made in the form of a hollow body of revolution in one piece with its own bottom, has the upper end open in the initial position and is pinched relative to the cover; according to an inventive concept, the bottom of the cover is equipped on the inside with an annular protrusion, which, in operation eat position, covered with a tightness of the bottle neck and the upper part of the capsule, in the operating position, it is covered with an interference fit protrusion.

In this design, the preload force arising from the preliminary assembly of the capsule with the cap before closing the bottle increases after capping due to the pressure of the neck on said annular protrusion. This is quite enough for reliable sealing of prize inserts in bottles with fruit and / or vegetable juices and nectars, beer and slightly carbonated mineral waters or soft drinks.

The first additional difference is that the lower part of the specified annular protrusion and the upper part of the capsule have counter-oriented ring hooks. This increases the reliability of sealing prize inserts in the necks of bottles filled with highly carbonated drinks.

The second additional difference is that the bottom of the capsule is equipped with at least one stiffening means selected from the group consisting of axisymmetric disk-like thickening and radially oriented ribs located at almost equal angular distances from one another. This further increases the resistance of the capsules to deformation due to changes in ambient temperature and the reliability of sealing prize inserts in the necks of bottles.

Brief Description of the Drawings

Further, the essence of the utility model is illustrated by a detailed description of its design and method of use with reference to the drawing, where the lid with a capsule for the prize insert is shown in the working position on the neck of the bottle (longitudinal section of the vertical plane of symmetry in an enlarged scale for clarity).

The best options for implementing the inventive concept

A device for placing a prize insert in the neck of a bottle (see drawing) has:

a cover 1, consisting of a practically flat outside of the bottom 2 and a screw skirt 3 with a specially designated tear-off control ring, and

the capsule 4 for the prize insert not shown here, which is made in the form of a hollow (cylindrical at least in the upper part) body of revolution integrally with its own bottom 5, has an upper end open in the initial position and pinched relative to the cover 1.

The bottom 2 of the lid 1 on the inside is equipped with an annular protrusion 6, which in the working position is covered with an interference fit of the neck 7 of the bottle, and the upper part of the capsule 4, also in the working position, is covered with an interference fit by this protrusion 6.

It is desirable that the lower part of the annular protrusion 6 and the upper part of the capsule 4 have counter-oriented annular hooks 8 and 9.

As a rule, the bottom 5 of capsule 4 is equipped with at least one stiffening agent selected from the group consisting of an axisymmetric disk-like thickening shown here and not shown (due to obvious fame for specialists) at least three radially oriented stiffeners located on practically equal angular distances from one another. One skilled in the art will also appreciate that such stiffening agents are integral with the bottom 5 of capsule 4 and that they can be oriented either outward or inward of capsule 4.

Lids 1 and capsules 4 are made of a polymer of arbitrary color suitable for contact with drinks (usually, opaque), for example, polyethylene, polypropylene, polycarbonate or polyethylene terephthalate (PET).

The described device is used in this way.

At least some capsules 4 from each batch insert prize inserts (in particular, rolled up bills or messages about other prizes). Then all (“charged” and empty) capsules 4 are inserted with an interference fit into the annular projections 6 of the lids 1.

If the lower parts of the annular protrusions 6 and the upper parts of the capsules 4 have counter-oriented ring hooks 8 and 9, then these hooks pop up one after the other, which increases the reliability of sealing the cavities of the capsules 4 and protect the prize inserts from being accidentally wetted by the advertised drinks.

Docked with capsules 4 caps 1 are used to seal bottles on automatic bottling lines of the corresponding drinks. During capping, the annular protrusions 6 of the lids 1 are tightened around the neck of 7 bottles and additionally compress the upper parts of the capsules 4 around the perimeter. This virtually eliminates the depressurization of the cavities of the capsules 4 when opening bottles with drinks.

After uncorking the bottles, consumers separate the capsules 4 from the caps 1 and determine the presence or absence of the prize (or message about it).

Industrial applicability

The proposed caps with capsules can be mass-produced on existing equipment for processing thermoplastics and used on existing lines for capping arbitrary bottles. This greatly simplifies and reduces the cost of production and advertising of drinks using prize inserts.
