Furthermore, the closure cap additionally comprises a withdrawable detachable lid that is designed so that it can axially and translationally move with respect to the outer body towards the opening, repeatedly open and close the container for using some of liquid and also visually indicate that the container has been opened and reclosed.

Description

The closure cap with a retractable lid The invention can be used in the food industry and relates to closures for bottles used for bottling and storage of alcoholic beverages, providing an indication of their opening and preventing re-filling of bottles of low-quality alcoholic products. There are various closures with retractable nozzles for draining the liquid: RF patent for utility model N ° 30726, B65D47 / 36, publ. July 10, 2007, RF patent for PM Nb 22937, MPK7: B65D 41/34; 41/38, publ. 05/10/2002; or with pouring tubes mounted on the housing with the possibility of longitudinal movement: RF patent for utility model Nb 65483, MPK8 B65D41 / 34, publ. August 10, 2007, RF patent for PM Nb 23290, MPK7: B65D 39/00, publ. 06/10/2002

Closures of this type usually consist of a decorative metal or plastic casing with an element indicating the first opening of the bottle, and a plastic cork with a drain device that extends upward and opens when turning the decorative casing of the bottle. When the casing rotates in the opposite direction, the cork acts as a shut-off valve, closing the opened bottle and thereby preserving its contents from evaporation. The disadvantage of this type of device is the design complexity, insufficiently high level of protection against unauthorized opening, as well as the ingress of foreign objects into the open pipe and the pouring tube after the first opening of the bottle.

In the technical solution according to the patent of the Russian Federation Nb 2180311 (MPK B65D 47/20, publ. 10.03.02), the drain device is made in the form of a sleeve with an annular protrusion with a thread on which a lid with a pipe for draining the liquid and slots on its outer side surface is installed. The tear-off element is located on the end part of the decorative casing, and the locking sleeve is made with slots on the inner surface and installed in the decorative casing with the possibility of their mutual rotation relative to the drain sleeve and the interaction of its slots with the slots of the cover for messages to her of axial displacement and separation by the tear-off element pipe. The disadvantages of these devices are:

- the constant openness of the outer opening of the sliding pipe, in which part of the liquid may remain, which contributes to the accumulation of various kinds of contaminants; - the ability to return the retractable pipe to its original position and restore the tear-off element, for example, using glue, which allows you to reuse the vessel with unauthorized liquid;

- repeated movement of the extension pipe in both directions often leads to jamming of the filling channel during operation due to the frequent change in pressure in the vessel when pouring liquid.

The closest in technical essence is the technical solution according to the patent of the Russian Federation for utility model JN ° 67550 (IPC B65D 41/34, publ. 10/27/2007)

The specified closure device contains fixed outer and landing bodies, a one-way valve with a locking ball and obturation rings to ensure a tight fit on the neck of the vessel, a figured sliding dispenser with a lid and a pouring element made integrally with its supporting body in the lower part, which has an external cylindrical surface stops. Before pouring liquid from the vessel, the outer casing is turned, introducing into the interaction the vertical edges of the lid and the corresponding ribs of the outer casing. There is a turn on the screw thread of the retractable batcher on the stops and its rise. As a result of the lift, the sliding dispenser squeezes the locking element of the lid and the control hatch of the outer cylindrical body, destroying the point connections of the locking element and the control hatch, respectively, with the lid and the outer case. When the protective housing is rotated in the opposite direction, the retractable dispenser is lowered and the pouring element is closed with the locking element of the lid.

However, this device complicates the design, does not provide sufficient tightness and reliability of closing the pouring opening of the sliding dispenser, and also does not provide reliable protection against unauthorized opening and is inconvenient in operation. In addition, it is possible to re-install the locking element of the lid, which may mislead the consumer. Closing the outer hole of the spout sleeve after opening during operation involves lowering the spout sleeve. Moreover, the operation of the device may be associated with the need for multiple rotation of the protective housing in the opposite direction with the actuation of all three movable structural elements, which increases the likelihood of jamming of the extension system. And the use of the above locking element of the lid during repeated opening and closing during operation leads to destruction and its complete separation. In addition, the locking element does not provide a tight and reliable closure of the pouring hole, which can lead to pouring liquid when the bottle is tilted.

The basis of the invention is the task of increasing the tightness and reliability of closing the pouring opening of the sliding dispenser by changing the design of the device, creating an additional level of protection, improving the usability of the device. The problem is solved in that the closure cap with a retractable lid that can be installed on the inlet and the neck of the liquid container contains an outer casing with an end wall on which there is a weakened line, a landing casing with fixing means on the container mounted in the outer casing, and also a pouring unit with an outlet located in the landing housing, while the closure cap includes a retractable cover that can be detached when the pouring unit is extended, and also means for extending the lid with the casting unit, configured to perform axial translational movement of the lid in the opening direction relative to the landing housing during the rotational movement of the outer casing, signaling the opening of the container.

In the particular case of the invention, the means for extending the lid with the casting unit is made in the form of lifting elements made on the casting unit, with the possibility of interaction with inclined surfaces made on the landing case.

In the particular case of the invention, a tear-off element is made on the outer surface of the end wall of the outer casing with the possibility of its separation along a weakened line as a result of the application of physical force when the cover is pulled out. In the particular case of the invention, the lid is connected to the casting unit by means of a threaded connection or by tight fit with the possibility of preserving the sealing of the closure in any position of the container.

Preferably, after the first opening operation of the container, the removable lid is configured to limit the return stroke when the container is re-closed.

The possibility of carrying out the invention, characterized by the above set of features, as well as the possibility of realizing the purpose of the invention can be confirmed by the description of the design of the closure device made in accordance with the present invention. The design description is illustrated by graphic materials, which depict the following:

The figure shows a general view of the closure cap in the open state with a partial section. The closure cap consists of an outer casing 1, a landing casing 2 installed in the outer casing, a retractable lid 3, a casting unit located in the landing casing, consisting of a spout sleeve 4 and a drain pipe 5.

The outer casing 1 is made in the form of a cylindrical sleeve element, on the end surface of which there is a tear-off element 6 with the possibility of its removal as a result of the application of physical force by the pouring unit when the container is opened. On the inner surface of the outer casing 1 in the upper part there are vertical thrust protrusions 7 and grooves 8, as well as fixing elements 9 for connecting with the landing casing 2 and holding it in the axial direction. On the outer side surface of the housing 1, corrugations 10 can be made for ease of use when gripping the consumer during opening.

The landing housing 2 is made in the form of a through cylindrical sleeve and consists of two integral parts: the upper 11 and the lower 12. In the lower part in the inner surface of the landing housing 2 there are made fixing means 13, 14 for a tight fit on the neck of the container, and there is also an annular platform 15 , in the lower part of which an annular protrusion 16 is made with a through hole 17 and a sealing element 18. In the upper part on the outer surface of the landing housing 2, guide inclined surfaces 19 are made, in the upper part of which angular sections with a horizontal edge 20 and a vertical edge 21 are formed. In addition, on the outer side surface of the landing housing 2 there are return stopping elements 22 in the form of a protruding flange, and the edge of the protruding portion of the flange is made clockwise in the direction of the opening.

The retractable removable cover 3 is made in the form of a cylindrical cap with a muffled upper end wall 23 and mounted on the spout 4. In this case, the outer cylindrical surface of the cover can be ribbed, and a sealing ring protrusion 24 is made on the inner surface of its end wall 24. The removable cover 3 is made with internal thread and mounted on the spout sleeve 4, interacting with its external thread, and with the possibility of multiple opening and closing of the container with partial use of liquid STI, ensuring its integrity in any position of the container. In this case, the removable cover 3 has a color gamut, a contrasting color gamut of the outer casing 1, and also the outer cylindrical surface of the lid can be ribbed or smooth.

Inside the landing housing 2 in the axial direction is a retractable casting unit, consisting of a pouring sleeve 4 connected by an integral connection to the drain pipe 5.

The spout sleeve 4 is made with an outlet 25. On the outer side surface of the spout sleeve 4 there are diametrically arranged lifting elements 26 for interacting with the inclined surfaces 19 of the landing housing 2 when the container is opened. The spout sleeve 4 comprises one or more peripheral holes 27 around the sleeve with a protruding element 28 formed between axially extending portions of the sleeve, the protruding element being located on the lower peripheral edge of one of the holes. The drain pipe 5 is made of elastic material and has a pipe

29 with a passage channel 30, installed by means of a sealing element 18 in the passage hole 17 of the annular protrusion 16, while maintaining the sealing of the closure in any position of the filling unit and container. On the side surface of the drain pipe, an outer annular portion is made O 31 for engagement with the protruding element of the spout sleeve 4 and fixation in the axial direction. In the upper part of the drain tube 5 between the outer 32 and the inner wall 33, stiffeners 34 are made with the possibility of preventing deformation during axial assembly with the spout sleeve 4.

The capping device is assembled with all parts as one unit. The drain pipe 5 is hermetically installed in the pouring sleeve 4, forming a pouring unit, a removable cover 3 is installed on the pouring sleeve 4. The assembled structure is then installed in the landing case 2 and fixed in the outer case 1. The closure device is installed and fixed on the bottle neck by means of fixing the landing housing 2.

The device operates as follows.

At the first opening of the device by turning the outer casing 1 in the direction of unscrewing, the thrust protrusions 7 and grooves 8 transmit motion through the lifting elements 26 of the spout sleeve along the guide of the inclined surface of the landing body 2, thereby leading the casting unit to translational-rotational motion, while simultaneously starting the lifting movement of the removable the cover 3, the spout sleeve 4 and the drain pipe 5. When lifting, the cover 3 presses on the end wall of the outer housing 1, as a result of which the tear-off element is removed. The lifting elements of the spout sleeve 4, moving along an inclined surface, go to a horizontal edge and are limited by a vertical stop edge, while limiting the further extension of the cover 3 in axial and radial directions. The removable cover 3 extends entirely outside the outer casing 1 and can be opened to pour liquid from the container. With partial use of the liquid, the cap 3 can be reused, while maintaining the tightness of the closure in any position of the bottle.

The inability to return the cover 3 to its initial position is provided by the locking element 22, which rigidly abuts against the thrust projections 7 and does not allow reverse rotation of the outer housing 1.

All parts of the capping device are made of environmentally friendly polymeric materials: polyethylene and polystyrene on high-performance injection molding machines on injection molds with a hot runner system and dies. Bottle capping is in progress pressing from top to bottom by means of a capping machine.

The present invention improves the tightness of the capping device with a sliding filling unit during repeated use of the container with the liquid, increasing the reliability of closing the pouring opening of the sliding filling unit, and also provides an additional level of protection against unauthorized opening.
