Description

Technical Field

[0001] The present invention relates to a closure device with a tamper-indicating element for bottles primarily intended for liquid products, such as alcoholic beverages. Background Art

[0002] In order to prevent unauthorized opening by means of tamper indication, various types of bottle caps use an indicator ring which remains on the bottle when the main part of the bottle cap is twisted off.

[0003] A technical solution disclosed in Russian patent RU2223209C2 published on February 10, 2004 is known, in which a sealing cap is used to seal a container (usually a bottle with a neck having a thread and an annular flange) containing an alcoholic beverage, the sealing cap being provided with a sealing device and an anti-tampering device, and comprising two assembled parts firmly connected in the rotational direction and the axial direction. An indicator band is used as an indicator device, made of a separate annular part, located at the lower part of the sealing cap, and connected to the screw cap by a bridge. The indicator band comprises an inner edge provided with an engagement device, the engagement device being a convex piece facing the inside of the bottle cap, fixed under the annular flange of the neck of the bottle. In the process of opening the bottle cap, the bridge is broken, the indicator band becomes clearly visible, and the indicator band can be stuck under the annular flange of the bottle, thereby preventing its reconnection with the bottle cap and making it difficult to be easily removed from the neck. A disadvantage of this type of closure is the risk of the indicator ring being accidentally torn off, since the connection of the indicator element to the bottle cap by means of a tie is not reliable enough and may be damaged before the first opening of the bottle, during the assembly phase and the subsequent closing or during the transport of the product with this bottle cap to the consumer, which reduces the reliability of this indication.

[0004] Also known is a closure cap disclosed in Russian patent RU191981 published on August 29, 2019, for bottles with threaded necks, comprising a screw cap, a housing, an indicator band made along the lower contour of the cap, the indicator band being releasable from the lower part of the housing. According to the patent, the indicator band is mounted between the interior of the housing and the outer surface of an annular element located in the lower interior of the housing, wherein a strength weakening line is made on the outer surface of the housing at the location of the indicator band. The disadvantage of this closure cap is the complexity of the product manufacturing, including the risk of displacement of the indicator band during capping or transportation.

[0005] Most similar to the present invention is a device for sealing a container with an edge disclosed in Russian patent RU2765085 published on January 25, 2022, which comprises a housing and a tamper-evident ring of the container, the housing being mounted on the edge of the container before the first opening, having a circular horizontal wall, an annular vertical wall extending downward from the circular horizontal wall, the tamper-evident ring of the container being attached from below to the annular vertical wall of the housing to form a detachable mechanical connection, the mechanical connection comprising an annular groove made in the annular vertical wall on the lower end surface of the housing. The disadvantage of this known technical solution is that the ability to protect the tamper-evident ring from accidental displacement or falling out of the annular groove during the assembly process is poor, and mechanical shocks may be caused to the ring when the external housing is installed, which will lead to a decrease in the quality of installation and unreliable operation after opening. Summary of the invention

[0006] The technical achievement achieved in this case is that the reliable operation of the anti-tampering device of the sealing device is ensured while maintaining the assembly order of the components of the device.

[0007] According to the invention, the aim and the specified technical result are achieved by a closure device for bottles, comprising a cap made of two separate parts in the form of an open sleeve and a closed sleeve, and an indicator ring coupled to at least one of the sleeves, wherein the installation of the indicator ring and the closed sleeve into the open sleeve is carried out in one direction.

[0008] Installing the indicator ring and the closure sleeve in this order in one direction into the opening sleeve makes it possible to eliminate any type of deformation of the indicator ring, thereby ensuring that it is securely placed in the closure device before the first opening.

[0009] The aim and specified technical results are also achieved according to a particular embodiment of the closure device according to the invention.

[0010] The closure device thus comprises a pouring sleeve mounted on the neck of the bottle.

[0011] Preferably, the closure device comprises an outer housing made of metal.

[0012] Preferably, the closure means comprises an outer housing made from a polymeric material.

[0013] Preferably, the sealing sleeve is manufactured to have an annular sealing protrusion.

[0014] In a particular embodiment of the invention, the closing device comprises a sealing element having an annular protrusion mounted in the closing sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The sealing device comprises a closure sleeve 1, which is made of an upper end wall and a side wall. On the inner surface of the side wall, there is a means for fixing the closure sleeve 1 on the neck of the bottle ( Figure 2 , Figure 3 ) or on a pouring sleeve mounted on the neck of the bottle ( Figure 4 , Figure 5). The fixing means have the form of a thread that interacts with the neck of the bottle or the outer surface and / or the thread of the pouring sleeve. The closure sleeve 1 can have means for sealing the neck of the bottle or the nozzle of the pouring sleeve in the form of an annular protrusion 2 on the inner end surface of the sleeve 1 or in the form of a separate sealing element 3 having an annular collar placed in the neck of the bottle or the nozzle of the pouring sleeve. The separate sealing element can be in the form of a disc-shaped gasket, the diameter of which is sufficient to seal the neck of the bottle or the nozzle of the pouring sleeve.

[0031] The device also comprises an open sleeve 4 and an indicator ring 5 which can be made to abut against the annular flange of the bottle, for which purpose a stopper 6 is made on its inner surface, for example in the form of a solid protrusion or a stopper tab. The indicator ring 5 can be placed between the closed sleeve 1 and the open sleeve 4 ( Figure 2 ), or can be placed so as to be coupled to a surface of one of the sleeves ( Figure 4 ).

[0032] The device may also comprise an outer casing 7 which at least partially surrounds the closing sleeve 1. This increases the rigidity of the closing sleeve 1 and thus the reliability and safety of the closure cap.

[0033] The outer housing 7 can be made of metal, such as aluminum foil, steel foil, etc., in particular by stamping, or of polymer, in particular by injection molding. During the manufacturing process, the coating and the marking means can be applied to the side and end surfaces of the outer housing 7 by methods such as hot stamping, offset printing, screen printing or pad printing, using white, colored, transparent or metallized varnish. The coating can also be applied by spray deposition or vacuum deposition.

[0034] In a preferred but non-mandatory embodiment of the present invention, the closing sleeve 1 can be made into an outer wall placed on the outer surface of the open sleeve (not shown in the figure). This makes it possible to increase the rigidity of the open sleeve 3 and further prevent the indicator ring 5 from being deliberately pushed back to its initial position after the closure cap is opened for the first time.

[0035] The closing sleeve 1 , the opening sleeve 3 and the indicator ring 5 are made of a polymer material, such as polypropylene or polyethylene, by injection molding.

[0036] The operational reliability and quality of the entire device and the tamper-evident control are achieved by the sequence of the installation of the indicator ring 5 and the closing sleeve 1 into the opening sleeve 4 in one direction, as Figure 1 This allows deformation of the indicator ring to be avoided, including eliminating operating errors of the tamper-evident device of the entire closure device.

[0037] When producing a closure device with an outer housing made of metal, the opening sleeve with the indicator ring 5 and the closure sleeve 1 are placed inside the outer housing 7 , the edge of which is crimped.

[0038] The claimed sealing device operates as follows.

[0039] When the closure device is first unscrewed, the closing sleeve 1 and the opening sleeve 3 are separated together along the threaded connection from the neck of the bottle or the outer surface of the pouring sleeve. In this case, the indicator ring 5 is released and remains on the neck of the bottle, signaling the first opening. When the bottle is closed again, the upper surface of the indicator ring 5 prevents it from returning to its initial position by preferably abutting against the lower end surface of the opening sleeve. However, other options are provided for the abutment of said surfaces of the ring, for example, against the lower edge or end of a metal or polymer housing or the like.

[0040] The proposed technical solution allows a more reliable mounting between the components of the closure device and thereby ensures that the tamper-evident control is prevented from being violated during assembly, transport and closure in factory mass production.
