- the ring 28 is thus restrained against any further rotation by the cylindrical sleeve. If the unscrewing action is continued, the weakened line 29 tears.
- the ring 28 is separated from the outer cap 19 and breaks up into the two portions 30 and 31 into which it is divided. The portions fall due to their own weight, sliding on the sloping shoulder 3a. They leave their initial positions for ever and, owing to gravity, can no longer be replaced or remain there.
- the inclinations of the faces of the teeth and of the opposing teeth prevent both a situation in which the two portions 30 and 31 into which the ring is divided are urged radially outwardly without tearing of the weakened line and with the teeth being overlapped by the opposing teeth, and a situation in which the two portions 30 and 31 are drawn radially inwardly with tearing of the weakened line but with the teeth firmly engaging the opposing teeth.
- the predetermined inclinations of the faces of the teeth and of the opposing teeth simultaneously ensure both the tearing of the weakened line and the separation of the two portions into which the ring is divided.
- the main advantage of the closure according to the present invention lies in the particularly unmistakeable manner in which any unauthorized opening becomes apparent, by virtue of the fact that it is impossible to reassemble the security ring.
- a further advantage of the closure according to the invention lies in its structural simplicity which is one of the most important advantages for an article which has to be produced on a very large scale.
Description
- The present invention relates to a security closure for bottles and the like, according to the preamble to Claim 1 (see EP-A-537530)-
- Although these known closures are advantageous from many points of view, they have a recognized disadvantage which, up to now, has not been overcome.
- In fact, after a non-authorized opening of the bottle, a person can, with patience and dexterity, reassemble the security band so that it adopts practically the same starting position. This may mislead a subsequent purchaser who does not notice that the closure has been tampered with.
- The problem upon which the present invention is based is that of devising a closure of the type specified which has structural and functional characteristics such as to overcome the disadvantage identified above.
- This problem is solved by a security closure according to
Claim 1. - Further characteristics and advantages of the closure according to the invention will become clear from the following description of a preferred embodiment thereof which is given by way of non-limiting example with reference to the appended drawings, in which:
- Figure 1 is a partially-sectioned view of a closure according to the invention with parts removed,
- Figure 2 is a section through the closure of Figure 1,
- Figure 3 a section through a detail of the closure of Figure 2, taken on the line III-III,
- Figure 4 is a view of the closure of Figure 1 at another stage of its operation.
- With reference to the appended drawings, a security closure, generally indicated 1, is intended for a bottle, not shown, particularly for good-quality liqueurs.
- The
closure 1 comprises apourer body 2, acylindrical sleeve 3, acap 4 and asecurity band 5, which are joined together coaxially along an axis X-X. - The
pourer body 2 comprises an internal obturator valve, generally indicated 6, for preventing refilling of the bottle and has anouter flange 7 and anexternal thread 8. - The
cylindrical sleeve 3 comprises an upper end 9 on which there is aninternal rim 10 which overlaps theflange 7, as well as an outer recess defined by a slopingshoulder 3a. Thecylindrical sleeve 3 has an internalannular lip 12 andaxial projections 13 which are intended to engage a groove and channels respectively provided in the bottle in order to fix the sleeve firmly to the bottle axially and with regard to rotation. - The
sleeve 3 in turn holds thepourer body 2 on the bottle axially by the engagement of therim 10 on theflange 7. A frontal coupling withteeth 14 is formed between theflange 7 and therim 10 to fix thepourer body 2 with regard to rotation relative to thecylindrical sleeve 3, and thus to the bottle. - The
cap 4 has external knurling 15 and aninternal thread 16 which, with theexternal thread 8, constitutes a threadedcoupling 17 for the screwing of the cap onto the pourer body and its unscrewing therefrom, according to need. - In particular, the
cap 4 comprises aninner cap 18 and anouter cap 19 which is fitted onto theinner cap 18. - Connection means 20 are formed between the
inner cap 18, which has theinternal thread 16, and theouter cap 19, which has theouter knurling 15, in order to fix the inner cap and the outer cap together. - In particular, the connection means comprise
external collars 21 on the inner cap and internalannular projections 22 on the outer cap, which are snap-engaged one above another to form acoupling 23 in order to fix the inner cap and the outer cap together axially. - In order to fix the inner cap and the outer cap with regard to rotation relative to one another, external
axial splines 24 on the inner cap and internalaxial splines 25 in the outer cap form a splined coupling 26. - The
splines tips - It should be noted that the
inner cap 18 is fixed to thecylindrical sleeve 3 by means of a weakenedline 27, the weakened line being produced by the action of blades after the inner cap and the sleeve have been moulded as a single item. - The
security band 5 is formed as aring 28 which is fixed to theouter cap 18 by means of a weakenedline 29. - The
ring 28 is substantially housed in therecess 11 and is substantially in contact with the slopingshoulder 3a. - The
ring 28 is divided into two structurally independent, identical,semicircular portions opposed cuts 32. - The weakened
line 29 and the twocuts 32 are produced by the action of blades after the outer cap and the ring have been moulded as a single piece. - A plurality of
external teeth 33, twenty-four teeth in the embodiment shown, is formed on thecylindrical sleeve 3 in therecess 11. A plurality ofopposing teeth 34, twelve teeth in the embodiment shown, is formed inside thering 28 for engaging theteeth 33 when the cap is first unscrewed. - The
teeth 33 and theopposing teeth 34 are intercalated with a predetermined pitch conforming to the predetermined pitch of the coupling of thesplines - The
teeth 33 and theopposing teeth 34 have sawtooth-like profiles with faces indicated 33a and 34a, respectively. The faces 33a of theteeth 33 are inclined rearwardly at an angle A, whereas thefaces 34a of theopposing teeth 34 are inclined forwardly at an angle B, with reference to the sense in which the cap is unscrewed. - The angles of inclination A and B have a predetermined value selected between 5° and 25° and in the embodiment shown are 15°.
- The
closure 1 according to the invention is assembled with all its parts as a unit which can be handled individually and is intended to be fitted on a bottle as such. - When the
cap 4 is first unscrewed, first of all, the weakenedline 27 between the inner cap and the cylindrical sleeve tears; the unscrewing then starts and continues until theopposing teeth 34 engage theteeth 33, face to face. Thering 28 is thus restrained against any further rotation by the cylindrical sleeve. If the unscrewing action is continued, the weakenedline 29 tears. At this point, thering 28 is separated from theouter cap 19 and breaks up into the twoportions shoulder 3a. They leave their initial positions for ever and, owing to gravity, can no longer be replaced or remain there. - The inclinations of the faces of the teeth and of the opposing teeth prevent both a situation in which the two
portions portions - The predetermined inclinations of the faces of the teeth and of the opposing teeth simultaneously ensure both the tearing of the weakened line and the separation of the two portions into which the ring is divided.
- The main advantage of the closure according to the present invention lies in the particularly unmistakeable manner in which any unauthorized opening becomes apparent, by virtue of the fact that it is impossible to reassemble the security ring.
- A further advantage of the closure according to the invention lies in its structural simplicity which is one of the most important advantages for an article which has to be produced on a very large scale.
- Naturally, an expert in the art may apply many modifications and variations to the closure according to the invention in order to satisfy contingent and specific requirements, all within the scope of protection of the invention as defined by the following claims.
