CAP FOR CLOSING BOTTLES,
Original Filed Aug. 51, 1929 Patented Aug. 16, 1932 .UNETED STATES PATENT OFFICE ERIC ARTHUR BLANCH, OF
STRAND, LONDON, ENGLAND,
ASSIGNOR zro WILLIAMS SEALING CORPORATION, OF DECATUR, ILLINOIS, A CORPORATION OF ILLINOIS CAP FOR CLOSING BOTTLES, JARS, AND OTHER Application filed August 31, 1929, Serial No. 389,675,
This invention relates to caps for closing bottles, jars, and other containers, the said caps being of the kind having a depending slotted flange or skirt which engages a divided ring, with the ends of which ring is connected a lever having a curved head provided with converging sides, whereby the ring is contracted to cause the cap to grip the mouth of the bottle or the like as the lever is turned down in a plane at right angles to the pull on the divided ring. The said caps have been provided with a cork or other resilient filling or lining covered with a disc of tinfoil or other thin material to prevent contact between the cork and the contents of the bottle or the like, but this disc has been liable to split or become detached.
According to the invention a number of concentric grooves or corrugations are pressed in the disc and in the filling, and the disc is provided with a circumferential flange which in the insertion of the filling into the cap is gripped between the edges of the filling and the inner surface of the cap, and to avoid splitting the tinfoil in consequence of any drag imposed on it in the operation of applying the cap to the bottle or other container stretching of the disc is permitted by the corrugated portions or concentric rings of the tinfoil leaving the grooves and flattening or opening out radially in the direction of such drag. WVhen the tinfoil has been Wrapped over the sides and the back of the cork or other filling, the said filling is inserted in the cap before the lever is connected with the cap, so that the cap is in a comparatively open position, allowing the insertion of the filling to be readily effected. The cap can then be pressed on the neck of the container without dislocation or displace ment of the disc, and detachment of the disc after temporary removal of the cap from the container is also avoided.
In order that the said invention may be clearly understood and readily carried into CONTAINERS effect, the same will now be described more fully with reference to the accompanying drawing, in which Figure l is a tion of a filling and disc ready for insertion into the cap.
Figure 3 represents a cap with the disc covering the filling in position therein.
A indicates the filling, B the tinfoil disc, 0 the cap, and D the lever on the cap. As seen in Figures 1 and 2, concentric grooves E are formed in the filling, into which grooves the material of the disc is pressed in the course of the formation of the said grooves by any suitable tool, While the disc is free to be re duced in diameter by reason of a portion of its substance entering the grooves; the 0utstanding edges of the disc can afterwards be pressed down by the same tool or another tool to produce a flange F enclosing the periphery of the filling. In assembling the cap, the fillingis inserted with the flange F inside the flange or skirt G of the cap, and is pressed into the cap, which is then tightened on it by the lever D in well-known manner when the complete cap is applied to the top of the bottle or other receptacle. During this assembling operation, the surface of the disc becomes flattened out, so that it merely bridges the grooves in the filling, and these grooves themselves tend to disappear owing to the resilient nature of the filling but while the disc is firmly secured in the cap, this is attained without any cracking of the disc, because of the presence of the reserve mate rial of the disc thus taken up from the grooves. It .s thus unnecessary to use any adhesive material between the isc and the resilient fillin What I claim and des re to secure by Let- ;:-:s Patent of the United States is A cap for closing bottles, jars and other containers, the said cap comprising a metallic skirt having a filling therewithin, the said filling comprising a cylindrical disc having plan and Figure 2 a cross secconcentric grooves or corrugations pressed into one of the circular faces thereof, a disc of metallic foil covering the said surface and pressed into the corrugations thereof and extending around the circumferential edge of the former disc, the composite disc fitting snugly Within the said skirt whereby, when the cap is applied to the neck of a receptacle, the metallic foil Will be drawn out of the corrugations.
