Description

The closure for a bottle with a retractable nozzle The invention relates to closures for a bottle with a valuable liquid that protects against refilling and signals the first opening of the bottle.

Known safety plug, incorporating a drain device, a fixing cap, a stopper, a locking sleeve. The cap and locking sleeve are connected by a weak line in the form of several jumpers. The drain device has ribs for distributing the flow over the free section. The locking sleeve on the inside has a flange for gripping the flange of the main device. The valve prevents refilling of the bottle (RF patent Ks 2150417, MPK7: B 65 D 49/02, publ. 10.06.2000). The disadvantage of this plug is its low reliability due to the small length of the initial valve base in the guide cavity of the drain device, with a slight inclination bottle valve may jam in the guide.

Recently, various closures with a sliding dispenser of various sizes have appeared (RF patent for ITM N ° 22937, MPK7: B65D 41/34; 41/38, publ. 10.05.2002). The closure consists of a decorative metal or plastic casing with an element signaling the first opening of the bottle, and a plastic stopper with a drain device that extends upward and opens when turning the decorative casing of the bottle (RF patent for PM Na 23290, MPK7: B65D 39/00, published on June 10, 2002). When the casing rotates in the opposite direction, the cork acts as a shut-off valve, hermetically closing the opened bottle and thereby preserving its contents from evaporation.

Also known is a polymer cap with a retractable valve, consisting of a decorative cover, a shut-off and drain sleeve, a drain pipe, a shut-off valve and a fixing casing. The drain device is made in the form of a drain pipe with the ability to seal the bottle cap with a shut-off valve. The drain pipe is turned out of the cavity of the cap when the decorative cover is unscrewed, the jumpers connecting the decorative cover with the safety ring are destroyed. which leads to the separation of the ring, signaling the first opening of the bottle (RF Patent Jfc 2238893, IPC 7: 65D 47/20, publ. 10/27/2004). However, the above closures do not provide reliable protection against unauthorized opening and are inconvenient to operate. In addition, it is possible to reassemble the tear-off safety ring, which may mislead the consumer.

The closest in technical essence and the achieved effect is a protective plug (RF patent N ° 2180311, IPC 7: B 65 D 47/20, publ. 10.03.2002), containing a decorative casing with a tear-off element, a locking sleeve and a drain device. The tear-off element is located on the end part of the decorative casing, and the locking sleeve is made with birds on the inner surface and is installed in the decorative casing with the possibility of their mutual rotation relative to the drain sleeve and the interaction of its splines with the splines of the cover to inform it of axial movement and tearing it with the tear-off element pipe. However, this plug also does not have a sufficiently high level of protection against unauthorized opening and is not tight enough both in a sealed state and in unscrewing and screwing.

The proposed technical solution is aimed at improving the reliability of the device, creating an additional level of protection, improving the usability of the cork.

The technical result indicated is achieved by the fact that the closure device for a bottle with a sliding nozzle contains a decorative casing, a locking sleeve with slots on the inner surface, a drain sleeve with a thread, on which a cap with a pipe for draining the liquid and slots on its outer side surface is installed, with this decorative casing is made with a tear-off upper part, weakened by vertical grooves, jumpers with different pitch are made on the side and end surfaces of the casing, while the last the lintel during the destruction is made reinforced, the ratio of the length to the length of the weakened lintel is at least 2.5, grooves are made on the inner surface of the decorative casing, and at least two restrictive flanges, and there are external ribs on the side surface of the drain sleeve with the grooves of the casing.

In a second embodiment of the closure device on the inside the surfaces of the decorative casing and the outer surface of the drain sleeve have a multidirectional thread.

The specified technical result according to the first and second embodiment is also achieved by the fact that part of the tear-off element of the casing has a rough surface. A tear-off element with weakened jumpers is made on the end surface of the locking sleeve, and a restrictive annular protrusion is made on the end inner surface of the locking sleeve. The cover with a nozzle comprises a cylindrical protrusion on which at least one sealing flange is made. The drain sleeve contains an elastic element with a through hole and protrusions forming an annular cavity open at the top, the lower part of the drain sleeve being located in the annular cavity with the formation of a gap between the bottom and the protrusions of the elastic element. The invention is illustrated by the following drawings: FIG. 1 is an assembled view of the cork, FIG. 2 - decorative casing, FIG. 3 is a top view of the casing, FIG. 4 is a view A in FIG. 2, FIG. 5 is a view B in FIG. 2, FIG. 6 is a view C in FIG. 3, FIG. 7 is a view D in FIG. 3, FIG. 8 - locking sleeve, FIG. 9 is a view E of FIG. 8; FIG. 10 is a view F of FIG. 8, FIG. 11 - a cover with a pipe, FIG. 12 is a view G in FIG. 11, FIG. 13 - drain sleeve, FIG. 14 - elastic element, FIG. 15 is a decorative casing with bi-directional thread according to the 2nd embodiment, FIG. 16 - drain sleeve with multidirectional thread according to the 2nd option. A capping device for a bottle with a sliding nozzle consists of a decorative casing 1, a locking sleeve 2, a cap 3, a drain sleeve 4 and an elastic element 5.

Decorative casing 1 is made with a tear-off upper part by making loosened jumpers 6 on the side surface and

105 jumpers 7 on the end surface, as well as dividing the upper part with vertical grooves 8. In the course of tearing, the last bridge 9 is made reinforced, the ratio of the length to the length of the weakened bridge is at least 2.5. The beginning of the tear-off element has a rough surface 10 with an indication of the tear-off direction 11. In the inner

110 of the lower part of the decorative casing 1, grooves 12 are made, as well as at least two restrictive flanges 13.

The locking sleeve 2 on its inner side is made with slots 14, on the end surface of the locking sleeve there is a tear-off element 15 with weakened jumpers 16. On the end inner surface of the locking

115 of the sleeve 2, an annular limiting protrusion 17 is made, in the lower inner part of the locking sleeve there is at least one annular slotted shoulder 18.

The cover 3 is made with a pipe 19 forming an opening 20 for draining the liquid. Thread 21 is made on the inner surface of cover 3, and on

120 of the outer surface - slots 22 for interaction with the slots 14 of the locking sleeve. Inside the cover 3, a cylindrical protrusion 23 is made with at least one sealing collar 24 to provide sealing of the closure device.

The drain sleeve 4 comprises an inner sleeve 25 with a plugged

125 butt. In the upper part of the drain sleeve 4 a cylindrical protrusion 26 is made with an external thread 27 interacting with a thread 21 on the cover 3. On the outer surface of the drain sleeve 4 there are ribs 28 interacting with the internal grooves 12 of the casing 1, as well as the locking grooves 29 and 30 for engagement with an annular groove 18 of the locking sleeve 2 and

130 restrictive flange 13 of the decorative casing 1, preventing its movement in the axial direction, and on the inner surface of the drain sleeve made ribs 31 for fixing on the neck of the bottle. The drain sleeve 4 comprises an elastic element 5 with a through hole 32 and protrusions 33 and 34 forming an annular cavity 35 on top. The inner sleeve 25

135 is installed with the possibility of arranging its lower part in the annular cavity 35, thus forming a water seal 36 (FIG. 1) and passage channels 37 (FIG. 1) for fluid leakage. The capping device is assembled as follows: an elastic element 5 is inserted into the lower part of the drain sleeve 4, and is put on top

140 cover 3 with pipe 19, locking sleeve 2 with tear-off element 15 and decorative casing 1 with upper tear-off part.

The drain sleeve 4 with a cover 3 is mounted to rotate relative to the locking sleeve 2. A decorative casing 1 made of a polymer material rigidly fixes the locking sleeve 2 with a cover 3 and

145 drain sleeve 4 on its inner surface by the shoulders 13, as well as internal grooves 12, interacting with the ribs 28 of the drain sleeve 4. The protective plug is mounted on the bottle, the bottleneck is fixed by the inner ribs 31 of the drain sleeve 4.

According to the second embodiment, the design of the closure device consists of

150 of the same elements as in the first, the differences are in the implementation of a new connection. On the inner surface of the decorative casing 1 and the outer surface of the drain sleeve 4 are made multidirectional thread 38, 39, respectively (Fig. 16, 17), which provides reliable protection of the casing from rotation and axial movement. Bi-directional thread may be

155 single start or multi start. This embodiment of the connection of the decorative casing with the drain sleeve excludes the implementation of such structural elements as grooves, ribs, flanges, which simplifies the design of the product, reduces the complexity of its manufacture. The assembly of this design is carried out by pressing the casing on the sleeve and locking the parts due to

160 tight fit specified thread.

The closure device is used as follows: they press the tear-off element with a rough surface 10 and, in the direction of arrow 11, tear off the upper part of the decorative casing, breaking the jumpers 6 and 7, made on the side and end parts of the casing. By performing different side and

165 end jumpers separation is easy without much effort. And due to the vertical grooves 8 in the upper part of the casing 1, the tear-off element is easy to fold, the end part, collapsing together with the side tear-off elements, remains on the last side element due to the reinforced jumper 9. Thus, the entire destroyed upper part of the casing remains

170 hand as a single unit, intended for ejection. Next, turn the locking sleeve 2, while together with it rotates the cover 3 relative to the bottle with the drain sleeve 4. Due to the interaction of the slots 14 of the locking sleeve 2 and the slots 22 of the cover 3, as well as the threads 27 of the drain sleeve 4, the cover 3 moves along the axis of the device. Cover 3 nozzle

175 20 extrudes the tear-off element 15 of the locking sleeve 2, breaking the jumpers 16. The pipe 19 extends beyond the locking sleeve 2.

When the bottle is tilted, the liquid enters through the through-hole 35 into the annular cavity 36 of the hydraulic lock 37 formed by the annular cavity 3 of the elastic element 5 and the inner sleeve 25, and then through the passageways 38

180 through the pipe 19 pours out of the bottle. When the bottle is returned to the vertical position, the liquid located in the passage channels 38 enters the annular cavity 36 of the hydraulic lock 37 and then into the bottle, creating excessive pressure that prevents further liquid flow. When the locking sleeve 2 returns to its original position, a dense

185 landing of the inner surface of the pipe 19 on the outer surface of the drain sleeve 2, which leads to reliable sealing of the bottle.

All parts of the closure device are made of environmentally friendly polymeric materials: polyethylene and polystyrene on high-performance injection molding machines by injection molding

190 forms with hot runner system and stamps. End bridges 7.9 and grooves 8 of the casing 1 were formed during injection molding, and side bridges 6 were made on a cutting machine. Bottle capping is performed by pressing from top to bottom by means of a capping machine.

Prototype Protective Bottle Stopper with Retractable Tube

195 was manufactured in the pilot mechanical production of the Belkaps IUPP on turning and milling equipment.

The present invention provides an additional level of protection against unauthorized opening due to the destruction of part of the casing, and also improves the reliability of the work when spilling liquid due to the absence of 00 mechanical parts in the drain sleeve, causing unpleasant consequences associated with their sticking and jamming.
