Description

CLOSURE
This utility model relates in general to food industry, and more particularly to closures for glass bottles used for bottling and storing in them expensive strong high-quality drinks.
The closest technical solution in terms of design is a closure including a cylindrical sleeve to be set on the bottleneck, a pouring tube and a check valve located inside the sleeve, a cap consisting of the outer and inner hoods, a threaded connection between the pouring tube and the inner hood to screw and unscrew the cap, and a tear collar used to indicate opening, which is attached to the outer hood with a number of breakable straps. The outer and inner hoods are equipped with fixing means to attach them to each other, and the cylindrical sleeve is attached to the pouring tube (RU N°2161585, Class B65D 41/38, 10.01.2001).
To assemble the known device, the outer hood will be attached to the inner hood which is an extension of the cylindrical sleeve, so that both of the hoods form a single part, i.e. a threaded cap fixed on the sleeve.
The design of the known seal has at least two obvious shortcomings. First, fixing the pouring tube inside the body during assembling is a complicate process as the pouring tube can be warped or get loose. Second, during the installation of the outer hood, the inner surface of the outer hood is to be moved relative to the external surface of the inner hood using some force before the fixing means can interact. Such means are usually horizontal annular grooves made in the one hood and horizontal collars in the other hood. It is clear that the collars enhance -friction and, consequently, increase force needed to install the outer hood. Therefore, using such a design can lead to breaking of the breakable straps of the tear collars used to indicate opening. Besides, making the threaded connection between the inner hood and the pouring tube is a rather complicated process.
The proposed utility model eliminates this problem owing to the fact that the tear collar used to indicate opening is located on the decorative casing, and the inner hood is not an extension of the cylindrical sleeve.
The utility model gives the following advantages:
1) - as the outer hood which is to be set on the inner hood using some force now has no tear collar used to indicate opening, the installation of the outer hood is greatly simplified and the probability of spoiling products at this stage is minimised.
2) - the design and the procedure of attaching the pouring tube to the cylindrical sleeve is simplified. In the proposed technical solution, the pouring tube is attached to the cylindrical sleeve by means of a number of breakable bridges.
3) - provision on the decorative metal casing of the tear collar used to indicate opening with a transverse cut and a partly deflected end or a perforated strip located in the area where the cap separates from the cylindrical sleeve eliminates a possibility of casual breaking the breakable straps and loosing the integrity of the tear collar used to indicate opening. Besides, any unauthorised opening of the bottle will be known.
4) - making the thread on the exterior side surface of the pouring tube as separate helical lines simplifies the casting of the pouring tube during fabrication of the closure and reduces material consumption. Breaks in the helical lines and the combined helix in which starting points of each thread are diametrically opposite, combined with the making of the pouring tube of a less ductile material as compared with the check valve and the making of the cap of a more ductile material as compared with the pouring tube ensure a more tight and secure pressing of the cap against the pouring tube.
The proposed utility model will now be described by way of the preferred example and with the reference to the accompanying drawings in which:
Figure 1 is a schematic view of the section of the proposed closure;
Figure 2 is an enlarged view, partly in section, of the outer hood (above) and the inner hood (below);
Figure 3 is a view of the pouring tube.
The closure includes a cylindrical sleeve 1 with a lower elongated skirt to be set on the common glass bottleneck (not shown in the Figure).
The cylindrical sleeve 1 contains a pouring tube 2 and a seal 3 with a check valve 4, on which a cap 5 is installed consisting of the outer hood 6 and inner hood 7. The exterior side surface of the pouring tube 2 has a thread 8 on it, and the interior surface of the inner hood 7 has a thread 9 on it, which make a threaded connection 10. The outer and the inner hoods 6 and 7 are fixed against each other by fixing means which are annular grooves 11 in the inner hood 7 and corresponding collars 12 on the inner surface of the outer hood 6 interacting with the aforesaid grooves. To exclude the rotation of the hoods relative each other, the upper interior surface of the inner hood 6 and the exterior surface of the inner hood 7 have, accordingly, vertical slits 13 and 14 forming a spline connection (see Fig. 2). Alternatively, vertical slits 13 H 14 can be made on the lower interior surface of the outer hood and the exterior surface of the inner hood (not shown in the Fig. 2).
The seal 3 can be attached to the pouring tube 2 and usually contains a check valve 4. The function of the valve 4 is to allow the liquid out of the bottle and prevent refilling of the bottle. The design of the pouring tube 2 is, in general, similar to common closure designs, but for one feature, namely the presence of a number of breakable bridges 15 on the lower end flange 16 used to make a connection with the cylinder sleeve 2.
The thread 8 on the exterior side surface of the pouring tube 2 is made as at least two separate helical lines 17 with breaks 18 in the form of flat bevels 19 located in parallel to the longitudinal axis 20 of the pouring tube (see Fig. 3).
. The thread 8 is made as a double helix in which starting points of each thread are diametrically opposite (not shown in the Figure).
The pouring tube 2 is made of a relatively rigid material, e.g. polycarbonate or polystyrene, and the check valve 4 is made of a softer and more ductile material, e.g. polyethylene or polypropylene.
The cap 5 is made of a plastic or polyolefin resin which are softer and more ductile materials as compared with the material of the pouring tube 2.
To facilitate operating the cap 5 and fixing on it the decorative metal casing 21, the exterior surface of the outer hood 6 has vertical slits 22.
The decorative metal casing is formed to the full height of the closure and has the tear collar 23 with a transverse cut 24 and a partly deflected end 25. The tear collar 23 is located in the area where the cap 5 separates from the cylindrical sleeve 1 and is attached to the decorative metal casing around its whole periphery by means of breakable straps 26. To simplify the design, one perforated strip (not shown in the Figure) can act as the tear collar.
The proposed closure is assembled as follows. The check valve 4 is installed into the seal 3, and these parts are placed into the cylindrical sleeve 1, which is attached to the pouring tube 2 with a number of breakable bridges 15, and moved into the pouring tube, using some dynamic force, through the lower flange 16. Then, using some force, the outer hood 6 is set on the inner hood 7 until the annular collars 12 come into engagement with the annular grooves 11. After this operation, the hoods are fixed together and form a single threaded cap 5, as rotation of the outer hood 6 will cause rotation of the inner hood 7 due to vertical slits 13 and 14. Then the cap 5 is tightly screwed on the pouring tube 2, the decorative metal casing 21 is tightly set on the cap 5 and the cylindrical sleeve 1, e.g. by means of gluing. The assembled closure is set on the bottleneck and fixed on it by a known means, e.g. using annular collars 27 on the inner surface of the cylindrical sleeve, engaging the collar on the bottleneck (the collar is not shown in the Figure). The vertical bottleneck ribs 28 on the inner surface of the cylindrical sleeve ensure additional tightness of the closure set on the bottleneck.
As the cylindrical sleeve is tightly set on the bottleneck by means of annular collars 27 and vertical ribs 28, the first opening of the bottle is carried out by pulling the deflected end first, relatively easy removing of the tear collar, and unscrewing the threaded cap. If there is a perforated strip on the metal casing, the first opening of the bottle results in breaking the strip, and the cap can be removed quite easily.
It is understood that the described embodiment does not restrict the proposed utility model, various embodiments of which are within the scope of the accompanying claims and are clear to a specialist.
