Description
- This invention relates to a closure for bottles as defined in the preamble of Claim 1 (see GB-A-1 421 572).
- A well-recognized requirement of closures of this kind is that they should form an individually manipulable unit, adapted to be stored and later transferred to the site for its application to a bottle, without its several component parts coming loose and getting lost.
- In particular, the washer should not separate from the side band.
- To fill this requirement, it is current practice to form a groove, such as by a rolling process, around the side band which is effective to forcibly engage with the washer and thereby retain it axially in place.
- Alternatively to the groove, locking spots are formed which are distributed at pitch distances around the band, causing the band to deform locally and become axially attached to the washer such that the latter cannot part from the band.
- Closures of this kind, while being widely utilized and achieving their objective, still leave something to be desired at the consumption stage from the standpoint of their manipulation and outward appearance.
- The groove or locking spots break, in fact, the continuity of the outer surface and make the closure inconvenient to manipulate, as well as rendering it aesthetically unattractive.
- The underlying problem of this invention is to provide a closure of the type specified above, which can overcome the above-mentioned drawbacks with which the prior art is beset.
- This problem is solved by a closure as indicated and according to the characterizing part of Claim 1.
- Further features and the advantages of a closure according to this invention will become apparent from the following detailed description of an embodiment thereof, given by way of non-limitative example with reference to the accompanying drawing figures, of which:
- Figure 1 is a part-sectional elevation view of a closure according to the invention;
- Figure 2 is a fragmentary elevation view showing in section the closure of Figure 1 at a first stage of its application to a bottle; and
- Figure 3 is a fragmentary elevation view showing in section the closure of Figure 1 at a successive stage of its application to a bottle.
- With reference to the accompanying drawing views, generally shown at 1 is a closure for a
bottle 2, said bottle having anend 3 and a collar 4 which locates at theend 3 and defines anundercut shoulder 5. - The closure 1 includes a
washer 6, substantially in the form of an annular disk, having an axis X-X, aperiphery 7, and a centrally located seat 8 for a one-way valve 9, in this example a glass ball. - A
pour body 10 is coupled to thewasher 6, coaxially therewith, by means of a male/female type of connection. Theconnection 11 consists of acylindrical seat 12, having a predetermined diameter and being formed in thepour body 10, and a two-diametertubular member 13 which protrudes from thewasher 6. Specifically, thetubular member 13 has a first section 14 with a smaller diameter, adapted to produce a slack male/female fit, and asecond section 15 with a larger diameter selected to produce a tight male/female fit. - A
cap 16 is threaded onto thepour body 10. Thecap 16 has atamperproof ring 17, to which it is attached through a rupture weakeningline 18. Said ring 17 abuts against aflange 19 protruding from thepour body 10 and being integral therewith. - A tubular band 20 of aluminum, lying on the axis X-X, has an upper edge 21 folded inwards to axially retain the
ring 17 andflange 19, as well as theperiphery 7 of thewasher 6. - The band 20 also has a free
lower edge 22. - In accordance with the invention, the closure 1 includes a
tubular spacer lug 23 extending inwardly of and coaxially with the band 20 and being fast with theperiphery 7 of thewasher 6. Thetubular spacer lug 23 is formed integrally with the washer and has a predetermined height dimension from theperiphery 7 of thewasher 6 to itsfree end 24. - An inwardly
bent border 25 is formed at thelower edge 22 of the band 20 to provide a stop in the axial direction for saidtubular spacer lug 13. - The height of the
tubular spacer lug 23 is selected such that, with thefree end 24 of the lug abutted against theborder 25, only the engagement of the first section 14 with thecylindrical seat 12, characterized by a degree of slack, will be operative and not that of thesecond section 15, characterized by a degree of tightness. - It should be noted that the
tubular spacer lug 23 has a predetermined thickness, to be selected so as to have the tubular spacer lug function as a sealing gasket driven radially between the band 20 and the bottle collar 4. - Preferably, a splined connection 26 is provided between the
tubular spacer lug 23 and the collar 4 which consists of anaxial spline formation 27 on thetubular spacer lug 23 inside and anaxial spline formation 28 on the bottle collar 4 outside. - The
cap 16 has analuminum overlay 29 which fits over aplastics core 30, being in turn a tight fit over the cap proper. - In manipulation of the closure according to the invention, (see Figure 1) the
washer 6 will be held captively with thepour body 10 by theband border 25 provided, against which border the tubular spacer lug abuts and is retained. - On the occurrence of this engagement situation, the
washer 6 andpour body 10 -- more specifically, thecylindrical seat 12 and the first section 14 of thetubular member 13 -- are engaged together loosely in a male/female interfit. - In this condition, the closure can be moved with no risk of any parts thereof getting lost, and can be stored even for a long time with no yield of the confronting materials in the male/female interfit.
- On assembling the closure to the bottle (see Figure 2) by axially fitting it thereover, the
washer 6 will abut against thebottle end 3, and thepour body 10 fit over thewasher 6, thereby a male/female interfit is established by thesecond section 15 of thetubular member 13 being driven into thecylindrical seat 12. - At this stage, the closure is associated immovably with the bottle through the tubular spacer member provided, and is ready to be permanently secured thereon by folding in, as by a rolling operation or the like, the
lower edge 22 of the band 20 (see Figure 3) against theshoulder 5. - A major advantage of the closure according to the invention resides in its improved handling capability and uniquely attractive appearance.
- It is also easier to manufacture.
- A further advantage of the inventive closure is that it can be attached to the bottle more reliably. It becomes indeed permanently associated with the bottle, once fitted axially thereon, by virtue of the tubular spacer lug provided. Also facilitated is the following operation of final securement of the closure on the bottle by rolling in the free edge of the band.
- An additional advantage of the closure according to the invention is that it will be held securely while the cap is screwed off, since any objectionable dragging of the washer around with the cap is positively prevented by the provision of a splined connection between the tubular spacer lug and the bottle collar.
- The closure outward appearance is further improved by the provision of an aluminum cap overlay extending in continuation of the band.
- It will be understood that the closure disclosed hereinabove may be modified and altered in several ways by a skilled person in the art to meet contingent and specific demands, within the scope of the appended claims.
