Description

The invention relates to closures for a bottle with a valuable liquid that protects against refilling and theft.

Known closures, including safety caps, described in domestic and foreign sources of information are known. Among the well-known analogues are: XV O 96/23904 A SVIO 8 TEU1 8.A. 08.08.96, B 65 Ό 49/04; VI 2150439 C1 Guala Closures S.p.A. July 6, 2000, B Ό 65 Ό 49/02; JV 2 099 414 P1 S1asoto Sia1a. 12/08/1889, B 65 Ό 49/06 49/34; MF 2 218 590 A Svio 8TEU1 8.A. 13.12.89, B 65 Ό 49/02.

The closures chosen for the analogs contain a drain device, a locking cap, a valve, a gasket, a stopper like a cap, and a locking sleeve. The cork, similar to the cap, and the locking sleeve are made as a single piece and connected together by means of a weak line in the form of several jumpers or tear-off half-rings. The cork, similar to the cap, and the locking cap are interconnected by coupling elements in the form of locks, ribs and make up the cover. The discharge device has ribs for distributing the flow over the free section, a guide cavity for the valve and a flange for sealing with the bottle through the gasket. On the inner side, the locking sleeve has a flange for gripping the flange of the discharge device and a flange for covering the collar of the bottle. The valve has check valve functions and prevents refilling of the bottle. A stopper, similar to a cap, is connected to a drainage device by means of a threaded connection and sealed to it with a conical sealing ring.

Although the known analogues are satisfactory from different points of view and, in essence, are suitable for their purpose, however, they have a number of shortcomings that manifest themselves in various situations.

Designs of analogues require high efforts to press in the closures on the bottle, which, firstly, reduces the speed and, consequently, the performance of the bottling lines and bottle capping, and secondly, the increased pressing forces create excessive deformation of the locking cap, often breaking it and marriage. Known designs involve the use of cork, similar to the cap, and the locking cap, with the elements of the coupling between them, which increases the cost of manufacture. Short bridges of medium-hard plastics (polypropylene) connecting the cork, similar to the cap, and the locking sleeve worsen the loosening effect, creating a high tear-off force of the cap. In known constructions, corks and fixing caps can be made only from materials with limited hardness, which does not allow the use of rigid transparent plastics (polystyrene, polycarbonate, etc.) and, accordingly, visually monitor the sealing of bottles.

In addition, it is known that with prolonged heating, the force for removing the closure decreases sharply due to the softening of the rim inside the closure hub covering the collar of the bottle, thus improper filling of the bottle with poor quality liquid is possible.

Destructible elements, made in the form of detachable half-rings, have a clear visible trace of the first opening of the bottle, but when destroyed they fall on the table or in the container for pouring. Semi-rings or their parts that fall on the table can cause the most unpredictable harm to the consumer.

Of the known devices, according to the technical nature and purpose, the safety cover described in patent VI 2150417, C1 MKI7 V 65Ό49/02, 10.06.2000 is the closest to the proposed technical solution.

This cover is selected for the prototype by the maximum number of similar essential features.

The safety cap chosen for the prototype contains the same elements as the closures selected for analogues. Additionally, the safety cap contains an annular liner of rigid plastic (polystyrene or polycarbonate), which has a C-shaped cross-section. The liner has a flange and a lock, which cover the flange of the discharge device and the collar of the bottle. In the safety cap selected for the prototype, there are common shortcomings inherent in this type of closures, taken as analogues. The following describes in detail the disadvantages of the safety cover, the elimination of which is the objective of the present invention.

In a safety cap, unlike analogs, the task of securing the closure securely on a bottle is solved by introducing into the design of a split Artificial liner made of rigid plastic and by the presence of a locking sleeve preventing the liner from opening. The presence of a lock made of rigid plastic covering the collar of the bottle increases the reliability of adhesion of the safety cap to the bottle, especially when heated, but the task of reliably attaching the safety cap to the bottle is not fully achieved. The locking sleeve suffers significant deformation when pressing the safety cap on the bottle. With a full (determined by the size of the collar on the neck of a real bottle) disclosure of the Shaped plastic sleeve, the specific tension of the closure hub should reach 6-7%. Such deformations go beyond elastic deformations for plastics. With this design breakage of the locking sleeve and jumpers occurs, and the force for pressing the safety sleeve increases dramatically. To avoid breakage of the locking sleeve and jumpers in the actual design between the locking sleeve and the C-shaped liner there is a significant gap, while reducing the stroke of the liner lock. The reduced stroke of the lock covering the collar of the bottle reduces the reliability of fastening and the tightness of the sealing of the safety cap on the bottle.

It has been found that by acting with a certain force in the axial direction, it is possible to remove the safety cap assembly.

If you follow this method of removal, perhaps any unauthorized filling of the bottle with liquids of poor quality.

In addition, the tightness of the closure with a limited course of the lock and significant gaps between the split C-shaped liner and the locking sleeve strongly depends on the accuracy of manufacturing the parts of the safety cap, as well as the actual size of the bottle neck. It is known that during transportation and storage of the bottle at variable temperatures due to the creation of a vacuum in the bottle or an overpressure, as well as different coefficients of thermal expansion of different materials, it is possible for the protective cap to depressurize.

The safety cap also has a drawback, which manifests itself during its pre-assembly, as well as the closure and opening of the bottle. It has been established that with a high speed of pre-assembling the safety cover and pressing it onto the bottle, rigid short jumpers connecting the cork, similar to the cap, and the locking sleeve, do not withstand dynamic loads and are destroyed. The destruction of the jumpers occurs even in the presence of a significant gap between the split C-shaped liner and the locking sleeve. In addition, the jumpers do not have a clear visual trace of the first opening of the bottle.

The destruction of the bridges, deformed during the preliminary assembly of the safety cap and its pressing on the bottle, occurs due to the transfer of significant elastic deformations of the parts (the plug, the locking cap, the C-shaped liner, the locking sleeve). The use of more rigid and brittle plastics for the manufacture of parts with destructible elements is all the more impossible. The use of rigid plastics (polystyrene, polycarbonate and others) for the manufacture of parts with destructible at the opening of the structural elements is preferable, since they have more stable strength characteristics at temperature changes and lower values of specific deformations at break. Lintels made of rigid plastics (polystyrene) are destroyed at certain pre-calculated loads, unlike viscous relatively soft plastics (polypropylene).

The technical result expected from the present invention is to increase the reliability of fastening the safety plug on the bottle, preserving the tightness of bottle capping at variable temperatures, preserving the integrity of the cork design elements at high assembly speed and bottle capping, reducing the pressure to press the bottle on the bottle opening the bottle, preventing the fall of destructible structural elements on the table, limiting the time required to open bottles, providing visual control over the tightness of the closure.

The technical result is achieved due to the fact that in the safety tube the tube contains locks weakened by U-shaped slits, while the outer walls of the tube between the locks have sections in the form of segments, and has a tear-off ring consisting of a thin shell and separate latches connected with the locking sleeve oblique bridges, and the attachment points of the jumpers to the shell are located offset to the latches, the cover and the locking sleeve are made of rigid material; The cover is made of transparent material.

Other distinctive features and advantages of the safety plug in accordance with the present invention will become clear from the description of its specific embodiment as a non-limiting example, with reference to the drawings.

The tube 14 has a step 29 on the outer surface that holds the locking sleeve 30, locks 11 with U-shaped slots 31 that hold the safety plug 4 on bottle 1. Between the locks 11 on the outer surface of the tube 14 there are sections in the form of segments 33. On the inner surface of the tube 14 there are ribs 34, which interlock with radial teeth 5 of bottle 1, and on the outer surface 35, which interlock with locking sleeve 3 0. Locks 11 have a conical guide part 36 and a locking cone.

37, which secures the safety cap 4 on the bottle 1 in the axial direction. The flow divider 15 includes a cap

38, which overlaps the central part of the free section of the discharge device 8, the ribs 39, which divide the free section of the drain device into separate channels. The detachable ring 23 has a cut 40. The lower part of the cap 38 is the stop for the valve 42. The drain device 8 is made of rigid, including transparent plastics, such as polystyrene.

The gasket 6 includes a cup 43, which is inserted into the central part 13 of the drain device 8, a flange 44 which is located between the drain device 8 and the bottle 1, a sleeve 45 which is inserted into the neck 2 of the bottle 1, a guide 46 on which the valve 42 is based ribs 47 that connect the guide 46 with the sleeve 45.

On the lower surface of the flange there is an inclined tab 50 that seals the stopper 4 with the bottle 1, and on the top there is a sealing edge 51, which is sealed with a valve 42. The gasket 31 is made of soft plastic, for example polyethylene.

The cover 18 consists of a main part 54, an upper part 55, a sealing ring 56, a detachable ring 23. The outer surface of the main part 54 has faces 57 and an internal thread 58 by means of which it is connected to a drainage device 8. In the lower part of the cover 18 there is a shell 60. The cover 18 is made of transparent plastics of increased rigidity, for example, polystyrene or polycarbonate.

The locking sleeve 30 has a detachable ring 23. The detachable ring 23 includes a shell 60, jumpers 62 and latches 22. The detachable ring 23 fixes the cover 18. The latches 22 cover the protrusion 21 of the cover 18. Jumpers 62 connect the detachable ring 23 to the main part of the locking sleeve 30 Jumpers 62 have slots 63. Jumpers 62 are located so that the attachment points of jumpers 64 on the sidewall are offset relative to the latches 22 by a certain distance. This distance is determined by the fulfillment of the condition that, with maximum deformation of the shell 60, the points 64 of fastening the jumpers 62 are located on a circle equal to the circle 65 attaching the jumpers to the main part of the locking sleeve 30. On the inner surface of the locking sleeve 30 there are steps 67 and 68, ribs 69. Locking sleeve 30 holds the locks 11 of the drain device 8 and the stopper 18 from loosening. The shoulders 67 and 68 fix the locking sleeve 30 axially with respect to the drain device 8. The ribs 69 of the locking sleeve 30 engage with the ribs 35 of the tube 14 and prevent the locking sleeve 30 from turning. The locking sleeve 30 is made of rigid and semi-rigid plastics, such as polystyrene or polypropylene .

The valve 42 is a ball of rigid plastic high density.

Pre-assembly of the safety plug 4 is as follows.

1. The valve 42 is installed between the ribs 39 of the drain device 8.

2. A gasket 6 is pressed into the assembly (drain device 8 - valve 42), while the sealing rings 48 of the gasket 6 are deformed and fit into the groove 27 of the drain device.

3. An assembly (gasket 6 - valve 42 drain device 8) is screwed onto the thread 58 and a cover 18 is screwed on. The sealing ring 56 is pressed against the conical surface 59 of the drain device 8.

4. For the assembly (gasket 6-valve 42, the pouring device 8-lid 18) the locking sleeve 30 is pressed in:

- the latches 22 are located on the conical guide 24 of the protrusion 21 and move in the radial direction;

- a thin shell 61 of the detachable ring 23 is elastically deformed into a polyhedron with snaps 22 at the vertices, while the faces move to the center relative to the original shape of the shell 61;

- during the deformation of the shell 60, the points 64 of attachment of the jumpers 62 on the tear-off ring 23 are moved counterclockwise, as viewed from the side of the cover 18;

- jumpers 62 under the action of axial forces are added;

- the upper plane of the main part of the locking sleeve 30 abuts against the shell 61, while the jumpers 62 are not deformed from the radial movement of the latches 22, since the points 64 of fastening the jumpers 62 on the shell 60 lie on a circle 65 equal to the main part of the jumpers 62 the locking sleeve 30;

- upon further movement of the locking sleeve 30, its main part acts directly on the shell 61;

- after the transition of the protrusion 21 of the latch 22 latches, and the shell 61 restores its shape;

- ledge 67 rests on the lower edge of the tube 14;

- the ledge 67 clings to the ledge 29 on the discharge device 8;

- the ribs 69 of the locking sleeve 30 engages with the ribs 35 of the discharge device 8.

The capping of the bottle 1 is made by pressing in the safety plug 4 in the collection.

Pressing consists of the following stages:

- the lower conical part of the locking sleeve 30, and then the tube 14 of the discharge device 8 pre-center the safety plug 4 relative to the neck 2 of the bottle 1;

- the tapered parts of the locks 11, weakened by the U-shaped slits, are found on the conical guide surface 7 of the bottle 1 and move in the radial direction;

- the outer surfaces of the locks 11 of the rounded shape burst the locking sleeve 30;

- the locking sleeve 30 is elastically deformed into a polyhedron with vertices at the locations of the locks 11 (Fig. 4);

- the faces of the polyhedron are embedded in sections in the form of segments 33 on the tube 14 of the discharge device 8, the presence of freedom to move the wall of the locking sleeve 30 in the direction of the center when it is deformed by the locks 11 makes it possible to ensure the maximum stroke of the locks, the absence of excessive efforts when pressing the safety plug 4 onto the bottle 1 and the destruction of the locking sleeve 30;

- the rings on the sleeve 45 are sealed on the inner surface of the neck 2 of the bottle 1;

- sealing petal 50 is deformed and seals the junction of the bottle 1 with the gasket 6;

- spike 28 is embedded in a soft gasket 6 and seals the connection of the drain device 8 with the gasket 6;

- after the transition of the protrusion 9, the locks 11 under the action of elastic deformations of the walls 32 of the locks 11 of the locking sleeve 30 are latched into the recess 10 of the bottle 1;

- the ribs 34 engage with the teeth 5 of the bottle 1;

- the locking sleeve 30 and the walls 32 of the locks 11 restore their original shape;

- the absence of a rigid connection of the detachable ring 23 with a lid prevents breakage of the jumpers 62 when pressing the safety plug 4 onto the bottle 1;

- a lid 18, made of transparent material, allows you to monitor the tightness of the capping of the bottle 1 and visually detect the causes of leaks.

Opening bottle 1 is as follows:

- the consumer tears off the tear-off ring 23;

- jumper 62 nadlamyvayutsya on the slots and come off, with the presence of the slots prevents the need for excessive effort;

- the consumer covers the sides of the hand 57 and unscrews the lid 18, holding the bottle 1 with the other hand;

- against turning the drain device 8 relative to the bottle 1 protects the adhesion of the ribs 35 with the teeth 5 of the bottle 1;

- tear-off ring 23 opens a bright control strip 26 on the side surface of the drain device 8;

- sealing ring 56 of the cover 18 moves away from the conical surface 17 of the drain device 8;

Pouring liquid from bottle 1 is as follows:

- bottle 1 bends;

- the fluid flow hits the valve 42;

- under the action of pressure and the weight of the liquid column, the valve 42 smoothly moves between the ribs 39, freeing the flow area in the gasket 6;

- the fluid flow is broken by the ribs 47 and 39, passes the drain edge 16 and falls into the receiving tank;

- air enters the bottle 1, passing the path of the liquid in the opposite direction in the upper part of the channel;

- bottle 1 is put in the initial vertical position;

- valve 42 under the action of gravity gently lowers onto the sealing edge 51 of the gasket 6;

- seal valve 42 relative to the gasket 6 occurs when installing a spherical surface relative to the edge 51 between the ribs 52 of the guide 46.

The closure of the cover 18 after the first opening is as follows:

- the cover 18 is screwed onto the drain device 8 along the thread 20,

- sealing ring 56 of the cover 18 is sealed with the neck 12 of the drain device

eight.

When an unauthorized filling of the bottle 1 is attempted with a poor quality liquid or other composition, the valve 42 is additionally pressed by the weight of the liquid column that it is trying to fill and reliably closes the flow area in the gasket 6.

When attempting to remove the safety plug 4 from the bottle 1, the locks 11, the fixing cones 37, abut against the lower part of the protrusion 9. The use of rigid plastics in the manufacture of the tube 14 with the locks 11 of the drain device 8, ensuring the maximum possible size of the fixing cone 37 and the progress of the locks 11 make it impossible to remove safety cap 4 of the bottle 1. Hard plastics have more stable strength characteristics when the temperature changes, this makes it impossible to remove the safety plug 4 from the bottle 1 d after preheating, and also increases the reliability of sealing tightness when temperature changes during transport, storage and use.

When pressing in the safety plug 4 on the bottle 1, the locking sleeve 30 changes shape within elastic deformations, therefore it stably regains its shape after pressing in and reliably keeps locks 11 from opening.

Improving the reliability of fastening and sealing the safety of the safety cap on the bottle is achieved by manufacturing a drain device made of rigid plastic (polystyrene) with a tube covering the collar of the bottle, as well as by the presence of separate locks weakened by U-shaped slots in the tube and sections in the form of segments. Locks have a connection with the tube only at the bottom. Segments in the form of segments are located on the outer surface of the tube between the locks.

There is no gap between the locking sleeve and the drain pipe.

When passing through the protrusion of the bottle neck, the tube locks, weakened by U-shaped slits, move freely in the radial direction and deform the closure sleeve within elastic deformations, turning it into a polyhedron. In this case, the faces of the locking sleeve are placed at the locations of the cuts in the form of segments on the outer surface of the tube. Thus, when the locks are as long as possible, only the shape of the locking sleeve within the limits of elastic deformations changes.

The operation of the locking sleeve within the elastic deformations makes it possible to ensure maximum locking of the locks covering the bottle shoulder, to reduce the force of pressing the safety plug on the bottle, to apply rigid, including transparent plastics for the manufacture of the drain device and the locking sleeve.

The maximum stroke of the locks ensures reliable fastening and sealing of the safety plug on the bottle.

In accordance with the present invention, the cover is made as a separate part.

When the cork is pressed into the bottle, elastic deformations of the cap and closure hub are possible. In the safety plug, in contrast to the prototype, the tear-off ring does not have rigid connections with the lid and has freedom of axial movement. Thus, the lintels of the detachable ring do not experience loads sufficient to destroy them at any assembly speed and when pressing in the safety plug on the bottle.

The locking sleeve snaps on the cover.

The main part of the locking sleeve and the detachable ring are interconnected by thin inclined ridges with slots. The detachable ring consists of a thin split shell and separate latches. The attachment points of the jumpers on the shell are offset from the locks by a certain distance. During the pre-assembly of the safety plug, when the closure sleeve is put on, the latches are located on the protrusion of the lid, the shell within the elastic deformations partially opens and turns into a polyhedron with latches in the tops. The faces of the polyhedron are shifted inward relative to the original shape of the shell. The fastening points of the jumpers are offset relative to the latches on the tear-off ring to such a distance that, with maximum deformation of the shell, the points of attachment of the jumpers on the shell are located on a circle equal in diameter to the circumference of the jumpers on the main part of the locking sleeve. Such an arrangement of the jumpers relative to the latches prevents radial movements of the jumpers during the preliminary assembly of the safety plug. When the closure sleeve is put on, the inclined bridges under the action of axial force are folded in the direction of pre-tilt, while the main part of the closure sleeve abuts against the tear-off ring. After contact of the main part of the locking sleeve with the tear-off ring, an increase in loads on the jumpers does not occur, since the shell of the tear-off ring takes up the axial load. With this design, the jumpers have a minimum load during pre-assembly, which allows the use of more rigid, including transparent plastics (polystyrene, polycarbonate and others). When you try to open the bottle by rotating the lid, the latch clings to the protrusion of the lid, jumpers work to break and withstand considerable force. Thus, it is impossible to open the bottle without removing the tear-off ring. Before opening the bottle, the tear-off ring is removed, and the jumpers are easily cut off alternately along the slots. The lintels of more rigid and brittle plastics, in contrast to relatively soft ones, have stable strength characteristics with a change in temperature, which allows one to strictly calculate the force for their destruction when removing the tear-off ring.

The use of rigid transparent plastics for the manufacture of caps allows you to visually monitor the tightness of the bottle capping.

On the side surface of the casting device there is a brightly colored control strip that opens when the separation ring is separated. The control strip is designed to visually fix the first opening of the bottle.

The prior art has not identified solutions that have the signs consistent with the distinctive features of the present invention, therefore, we can assume that the proposed technical solution meets the condition of the inventive step.

The main advantages of the safety plug in accordance with the present invention with respect to the safety cover selected for the prototype are:

- increased reliability of the bottle capping,

- improved ability to withstand the opening of the bottle by removing the safety plug by unauthorized persons,

- reduction of efforts when pressing in the safety cap on the bottle,

- preservation of the integrity of destructible elements (jumpers) at a high speed of preliminary assembly of the safety plug and its pressing on the bottle,

- limiting the effort required to open the bottle,

- the presence of a clear visual trace of the first opening of the bottle,

- the possibility of using rigid transparent materials for the production of parts of the safety plug and visual inspection of the tightness of the closure.

The advantages of the safety plug in accordance with the present invention are particularly important, suggesting that the product should be made in the amount of hundreds of millions.

In order to meet specific requirements it is possible to make various modifications and changes to the design of the described safety plug, however, all of them must be within the scope of the present invention.
