Description

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.

Various closures with retractable nozzles, dispensers for draining the liquid, in which various elements of the lifting mechanism are made, are known.

For example, in a cap with a drain pipe according to the patent of the Russian Federation 2238893 (IPC Β65Ό 47/20, publ. 10.27.04), the specified pipe is lifted due to the gear interaction of the closure cap and the drain pipe, which transfers the axial and translational rotation of the pipe with its threaded guide along threaded locking sleeve and gives it a progressive upward movement.

In the technical solution according to the patent of the Russian Federation No. 2180311 (IPC Β65Ό 47/20, publ. 10.03.02), the extension of the sliding nozzle is carried out due to the interaction of the outer slots of the cover with the nozzle with splines of the locking sleeve made on the inner surface, as well as with threads on the drain sleeve As a result, the cap with the nozzle moves along the axis of the protective plug.

The disadvantages of these devices is the complexity of the design of the lifting system of the retractable elements, which does not provide ease of use due to the high force during opening during translational movement towards opening.

The closest technical solution is a capping device with a sliding dispenser, consisting of a lift and a pouring element. The upper part of the prefabricated retractable batcher lift has the shape of a figured flange with stops for interacting with the stops of the prefabricated retractable batcher pouring element and screw threading the cover, and the upper end of the specified hollow polyhedron at the interface with the curly flange of the elevator forms a saddle of the said one-way valve, inside the specified hollow cylindrical cap a drain pipe is inserted, in which, in turn, with the possibility of vertical movement, the lower part of the elevator with a stopper is inserted, In fact, the outer cylindrical body is fixed on the lower body through the interaction of its stops and the supporting surface of the lower body (RF patent for ПМ № 73652, IPC Β65Ό 41/34, publ. 27.05.08). Before the liquid is poured, the outer cylindrical body is rotated, engaging the lug stops and the lugs of the outer case. There is a turn on the screw thread of the hoist of the assembled retractable batcher on the stops and its rise together with the pouring element.

The disadvantage of the prototype is the complexity of the design of the extension system of the dispenser for screw cutting, the presence of a large number of parts, the inability to control the opening force, which is inconvenient when used, and the application of a certain physical force during opening.

The objective of the invention is the creation of a lifting unit for a capping device with a more simplified and reliable system of extending the pouring unit in the direction of opening and vice versa, which allows you to adjust the lifting force with minimum torque and increase the usability of the capping device.

The problem is solved in that the lifting unit of the sliding block of the capping device contains an outer rotary housing, a landing housing and a casting unit installed in the outer rotary housing, and the casting unit is made with the possibility of axial vertical movement relative to the landing housing during rotation of the outer rotary housing, while the landing the housing has at least one cutout made on the side wall, which forms at least one lifting guide surface, on the outer side surface of the pouring assembly formed at least one projecting supporting protrusion, which interacts with the outer casing and the lift guide surface.

Preferably, at least two thrust protrusions are made on the inner surface of the outer rotary housing to form a groove between them to accommodate the support protrusion of the casting assembly with the possibility of transmitting movement due to pressure on the support protrusion and its sliding along the lifting guide surface of the landing housing.

Preferably, the lifting guide surface of the landing housing is made with a constant or variable angle of inclination with the possibility of regulating the lifting force of the sliding block of the capping device when opening.

Preferably, the lifting guide surface of the landing housing is made with a transition to the horizontal landing and vertical thrust plane with the possibility of placing the supporting protrusion of the casting unit in the end extended position of the casting unit and restricting further vertical movement of the sliding block of the capping device.

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:

in FIG. 4 shows the landing housing;

in FIG. 5 - locking cap;

in FIG. 6 - pouring sleeve;

in FIG. 7 - drain pipe;

in FIG. 8 - outer rotary housing.

The lifting unit of the sliding block of the capping device consists of a landing body 1, a locking cover 2, a casting unit 3 with a pouring tube 4. The lifting unit is installed in the outer rotary housing 5.

The landing housing 1 is made with at least one lifting guide surface 6, which becomes horizontal 7 and is limited by a vertical thrust plane 8 (Fig. 3). In FIG. 4 shows an example of the execution of the landing housing 1 with two inclined surfaces, as the most optimal option for the operation of the sliding unit. The landing housing 1 has fastening means 9, 10 on the bottle, as well as a base 11 with a central hole 12 and a sealing element 13 for a tight fit in the opening of the neck of the bottle.

The locking cover 2 is made with an internal thread 14 and an annular sealing protrusion 15. The locking cover 2 may have a color scheme that contrasts with the color scheme of the outer casing 1.

The casting unit 3 has an external thread 16 that interacts with the internal thread 14 of the closure cover 2, at least one protruding support protrusion 17 is made on the outer surface of the casting unit 3, interacting with the outer casing 5 and the lifting guide surface 6 (Fig. 6). In FIG. 6 shows the implementation of 2 bearing protrusions in accordance with two lifting guide surfaces 6 of the landing housing 1. On the surface of the casting assembly 3, engagement elements 18 are made with a drain pipe 4. The drain pipe 4 is made with an elongated pipe 19, which allows sealing to be sealed in any position of the filling block, a passageway for liquid 20. In addition, the drain pipe 4 in the lower outer part has an annular protrusion 21 for tight fixation with the engagement elements 18 of the pouring tube 3 in the axial board for vertical translational-rotational movement therewith.

On the end surface of the wall of the outer rotary housing 5, a weakened line 22 is made with a decrease in the wall thickness and with the possibility of wall destruction along this line as a result of the application of physical force. In the upper part on the inner side surface of the housing 1, thrust protrusions 23 are made for transmitting movement when lifting the casting unit 3 with a locking lid

2. On the inner side surface of the housing 1, there are at least two locking stops 24 for holding the landing housing 1 after assembly of the product.

The lifting guide surface 6 of the landing housing 1 can be made with a constant or variable angle, which allows you to share the lifting force of the sliding block. At a constant angle of inclination, the lifting force is distributed evenly throughout the movement towards the opening, with a variable angle of inclination, the opening force can be controlled, i.e. at minimum torque, achieve maximum lifting force. The lifting guide surface 6 can be made with a slotted vertical wall, which will reduce the torque of the outer rotary housing 5.

The lifting unit is assembled with all parts as one unit. The drain pipe 4 is hermetically installed in the filling unit 3, the closure cover 2 is installed on the pouring sleeve 3, then the pipe 19 is installed in the central hole 12 of the base 11 of the landing housing 1. The assembled assembly is then installed and fixed in the outer rotary housing 5. Next, the closure is installed and fixed on the neck of the bottle by means of 9, 10, as well as in the neck of the bottle through the base 11 of the landing housing 1.

The device operates as follows.

At the first opening of the device by turning the outer casing 5 in the direction of unscrewing, the thrust protrusions 23 of the housing 1 transmit motion through the support protrusions 17 of the casting assembly 3 along the lifting guide surface 6 of the landing housing 1, while simultaneously starting the lifting movement of the closure cover 2, the casting 3 and the drain pipe 4. When lifting, the closure cover 2 presses on the end wall of the outer casing 5, which is torn off by breaking the weakened line 22. The supporting protrusions 17 of the casting unit 3, moving along the lifting turn x 6, go to horizontal 7 and are limited by a vertical thrust plane 8, while limiting the further extension of the casting unit 3 with the lid 2.

The lifting unit does not restrict the movement of the casting unit in the opposite direction, i.e. towards the closing direction. If necessary and in order to reduce the cost of the device, the filling unit 3 can be carried out without the locking cap 2. The filling unit can be extended and retracted repeatedly.
