Definitions
- the invention concerns a grip-on cap seal for bottles and other containers, the cap being fitted with a sealer insert of relatively thin and pliable plastic material.
- This insert has a head covering the mouth of the bottle whilst the actual sealer portion protrudes into the bottle neck.
- the invention is particularly applicable to the Crown type of cap seals.
- Object of the invention is a cap seal which, whilst suffering visible deformation when the bottle is opened the first time, may nevertheless be used for repeatedly closing the bottle, even one containing an aerated liquid.
- the sealer insert must be firmly anchored inside the grip-on cap, and in a manner both technically simple and suitable for mass production.
- the invention refers also to a method of production of grip-o-n cap seals.
- the sealer portion of the plastic insert protrudes in known manner sufliciently far into the bottle neck, for its outer wall to press tightly against the inner wall of the neck. Were the insert to be separated from the grip-on cap after the first decapping and pressed back onto the mouth of the bottle without the cap, an effective re-closing would be possible.
- the base of the sealer portion has a turret-like protrusion reaching towards the grip-on cap, with a riveting stump of smaller diameter.
- the cap has a central hole of equal size whence the stump is inserted to be deformed-by suitable heat application-- into a rivet head. It is advisable to make said turret protrusion hollow so that it can take the dolly when riveting, thus to reduce the elastic deformation during this process.
- the resulting depression will take the rivet head, as described above. If the riveting stump is accurately dimensioned, the formed rivet head will just fill the countersink without rising above the cap surface.
- FIG. 1 shows a grip-on cap of the Crown type with a central hole
- FIG. 2 depicts a sealer insert to be applied therewith
- FIG. 3 shows the marrying of grip-on cap to sealer insert
- FIG. 4 depicts diagrammatically the process of supporting, heating and plastic deformation, whilst FIG. 5 shows the completed grip-on cap closure.
- the grip-on cap 1 is provided with a central hole 2, the edge 3 of which is depressed in countersunk manner.
- the wall 6 rises to the turret-like central portion 7. It forms an annular shoulder 8 whose edge 9 falls oflf obliquely towards the centre from which rises the riveting stump 11.
- the edge 3 and edge 9 are correspondingly shaped and therefore fit well one into the other, as is evident from FIG. 3.
- shoulder 8 is supported by means of a dolly 12 whereby the edge 3 of the grip-on cap derives a firm counter base which prevents edge 3 from being flattened out again when subsequently the riveting stump 11 is plastically deformed.
- the riveting stump 11 is heated by means of contact heat, or is subjected to impinging heat such as hot air from one or more jets 13, and is then pressed onto the-preierably cold-dolly 14, the grip-on closure attains the shape shown in FIG. 5.
- a grip-on cap seal for a bottle or the like which comprises (A) a metal grip-on cap having a central hole therein, the annular portion of said cap immediately surrounding said hole being depressed from the upper planar surface of said cap and forming an inwardly inclined anchoring flange, and (B) a pliable insert member positioned against the undersurface of said cap, said insert member having a hollow generally cylindrical stopperforming part protruding away from said cap and adapted to project into and sealingly engage the inner wall of the neck of a bottle, said cylindrical stopper-forming part being connected at its lower end with the lower end of a smaller cylindrical part which is positioned within said stoppenformng part and is closed at its upper end by a central portion carrying a rivet-headed stump, said rivetheaded stump protruding upwardly through said central hole in said cap and being formed to substantially fill the space within the depressed portion of said cap with the upper surface of said rivet-headed stump being substantially coplanar with the upper surface of said cap, said insert member being arranged to embed both the upper and
- a grip-on cap seal for a bottle or the like which comprises (A) a metal grip-on cap having a central hole therein, the annular portion of said cap immediately surrounding said hole forming an anchoring flange, and (B) a pliable insert member positioned against the underinsert member being arranged to embed both the upper 10 and the lower surface of the anchoring flange of said cap to establish an inseparable connection therewith, said anchoring flange and said rivet-headed stump being spaced radially inwardly from the inner wall of said cylindrical stopper-forming part.
