Abstract
ABSTRACT OF THE DISCLOSURE
A tear-off closing cap comprising a flat disc-shaped part made of a light metal and having a circumferential flap for application to the neck of a bottle. On the disc-shaped part there are two lines of incision which delimit a tear-off band and extends in the form of a pullout tongue. The tear-off band has on the part two lateral zones on the bottom surface of which is attached to a disc-shaped gasket which is not fastened to the band.

Description
The Present invention relates to a tear-off closure cap for closing bottles.
Caps for closing bottles, made of light metal and comprising a circumferential flap clasped to the edge of the bottle opening and an overhanging flat disc-shaped part, wherein there is a central tear-off band that crosses the circumferen-tial flap and extends beyond same in a pullout ton~ue are known.
The seal of the closure is generally assured by a disc-shaped or ring gasket disposed between the top edge oE the bottle open~
ing and the bottom surface of the disc-shaped part. For use, these caps must inter alia meet the following two re~uirements:
(a) the neck of the bottle must be easily removable from the cap; and (b) the caps must be t~nporarily reusable even after tear o~f.
'rO reconcile khese re~ui,rements~ which in practice ~:iv~ rise to contrasting problems, there has already been pro-posed(British patent No. 1,320,~90) a cap with a disc-shaped gasket skuck to the bottom surface of the disc-shaped part of
Caps for closing bottles, made of light metal and comprising a circumferential flap clasped to the edge of the bottle opening and an overhanging flat disc-shaped part, wherein there is a central tear-off band that crosses the circumferen-tial flap and extends beyond same in a pullout ton~ue are known.
The seal of the closure is generally assured by a disc-shaped or ring gasket disposed between the top edge oE the bottle open~
ing and the bottom surface of the disc-shaped part. For use, these caps must inter alia meet the following two re~uirements:
(a) the neck of the bottle must be easily removable from the cap; and (b) the caps must be t~nporarily reusable even after tear o~f.
'rO reconcile khese re~ui,rements~ which in practice ~:iv~ rise to contrasting problems, there has already been pro-posed(British patent No. 1,320,~90) a cap with a disc-shaped gasket skuck to the bottom surface of the disc-shaped part of
2~ the cap itself but corresponding to a zone opposite the pull-out tongue and arranged transverse to the incisions. In this way the in.itial tear-oEf of the cap is not hindered by the disc-shaped gasket, which remains intact and affords subsequent reuse of the cap itself. A disadvantage of this is that the reclosable nature of the cap for subsequent usage is basically dependent on the residual elasticity of t'he metal of which it is made. ~lowever, after two or three uses on the bottle, the residual elasticitv of the metal is nearly exhausted, and there-fore -the now unreliable reclosure continues to lose its efEective-ness.
~ ccording to the present invention there is provideda tear-Qff cap ~or closing bottles made o~ h-t metal Wi-t}l a ~$
circumEerential flap and an overhanging flat disc-shaped part, a tear~of~ band which crosses the circumferential flap and ex-tends beyond same in the form of a ~ullout tongue, and a disc shaped gasket fastened only partially to the bottom surface of the disc-shaped metal part, the disc-shaped gasket being fastened to said disc-shaped metal part corresponding to two zones outside the t~ar-off band.
In this way there is provided the advantage of having a reclosure that depends on the elasticity of the disc-shaped yasket, which not only does not weaken even after numerous re-closings, but also enables the cap, even when torn, to assume the same position it had before the tear-off, thus constituting a reclosllre in an "active" rather than passive sense.
Also according to a preferred embodiment of the in-vention, the tear-off hand can be delimited by two lines of incision which consti1:ute the extensions of the pullout tonyue edg~s and which stop at the part opposite said tongue before reclchi.ng the free edge of the clrcumferential flap.
The present invention will be further illustrated by way o~ the accompanying drawings in which:-Figure l is a perspective view of a cap according toone embodiment of the invention applied to a bottle;
Figure 2 is a sec-tion taken along the line II-II of Figure l, and Figure 3 is the same view as Figure ~ after tear-of f and subsequent reapplication to the neck of the bottle.
. Referring to the drawings, the tear-off cap according to the invention is made of a metal and comprises a disc-shaped -Elat upper part (l) encIrcled by a downwardly turned flap (2~. Starti~g from one zone of the -flap is a pullout tongue (-3I, the edges of which extend al.ong two lines of ~i~nci5Ion (4) which completely cross the flap (2) and the --2~
s~
the disc-~haped part (1~, stopping on said flap in a position opposite the tongue (3). The two incisions (4) thereFore pro-vide a tear-off band (5~, which basically constitutes the extension of the tongue (~) on the disc~shaped part (1), and two lateral parts (6).
On the disc-shaped part (1) is a seal gasket (7).
It is ,fastened to the bottom surface of said circular part but only on the two lateral parts (6), thus ]eaving completely ~ree the tear-off band (5) and the two incisions (4) which delimit it.
For the first application to the neck of the bottle, the cap according to the invention requires the same operations that are conventionally required by other caps and which therefore have no need of further description.
Also at the moment of pullout, the operations that khe user must do are basically the same. It should be noted that the interruption of the incisions (4) allows the torn cap to remain in one piece.
The cap is removed ~rom the neck (8) oE the bottle due to the elastic yielding of the disc-shaped gasket (7), ~hich enab]es the separation of the two opposite sections (9) o~ the flap, with the relative parts (6), from the neck (8) of the bottle. After the cap has been completely removed, the elasticity of the gasket (7) bring those flap sections (9) back - to kheir original position. To reapply the cap to the bot-tle, the operation can be easily and effectively done by gently pulling apart the two sections (9) of the flap (2) and thus subjecting to tension the disc-shaped gasket (7) which, once the cap has been reapplied, brings both sections (9) back to the original closure position.
Thusr in the cap according to the invention, the disc-h~ped gasket ('7) performs, besides the conventional Eunction --3 ~
S3~i consisting in assuri.ng a closing seal, the further function of elastically preserving the original shape of the cap and thus affording an almos~ unlimited number of active reclosings.
