Description

W. EMMELIUS.
METALLIC CAP CLOSURE.
APPLICATION FILED AUG. 13, 1907.

WITNESSES INVENTOR mi mmw izfw I V I ATTORNEYS UNITED STATES PATENT OFFICE.
WILHELM EMMELIUS, OF GODESBERG, GERMANY.
METALLIC-CAP CLOSURE.
To all whom it may concern:
Be it known that I, WILHELM EMMELIUS, a subject of the King of Prussia, residing at 19 Diirenstrasse, Godesberg-on-the-Rhine, Germany, have invented certain new and useful Improvements in Metallic-Cap Closures, of which the following is a specifica tlon.
It is common in metallic caps for bottle or can closures to break the lateral flange or sealing ring by means of a tongue formed in the bottom of the cap. This flange is usually grooved or U-shaped in cross-section, so that if torn through only at one place the cap can be removed only by bending the cap upward. WVhile this may be done where the cap is constructed of soft metal, for example aluwmmr where the cap metal is thin only a small amount of metal being employed, it is very diflicult where the cap is constructed of a harder metal or metal of greater thickness, more metal being employed. This difliculty is met in caps constructed of tin plate which is the metal most available in the manufacture of caps at low cost. In order to obviate this difliculty, I provide two tongues formed in the cap bottom by suitable incisions.
In the accompanying drawings, Figure 1 is a plan, and Fig. 2 a vertical section of a cap embodying my invention applied to a bottle head.
In Fig. 1 of the accompanying drawing I have shown a cap in plan view, with the tongues a and I) located directly opposite one another.
The cap is not materially weakened by the incisions necessary to form the tongues and in most cases, therefore, especially with small metallic caps, the use of a special metal pro- Specification of Letters Patent.
Application filed August 13, 1907.
Patented July 2'7, 1909.
Serial No. 388,344.
tecting disk under the cap may be done away with.
By the use of both tongues it is possible to break the sealing flange c at two points diametrically opposite. The halves thus formed may be readily removed laterally in the direction of the arrows, without bending the cap upward as is necessary in the constructions previously employed.
I claim as my invention:
1. A metallic sealing cap having a lateral sealing flange and provided with rip tongues cut in the top of the cap at diametrically opposite points so that the free ends of said tongues approach each other, the length of said tongues being such as not to materially weaken said cap, whereby said sealing flange may be broken at opposite points and the divided cap parts removed laterally without bending the portions of the sealing flange thereon, substantially as described.
2. A metallic sealing cap having a lateral sealing flange and provided with diametrically opposite rip tongues cut in the top of the cap, one of said tongues at least being of less length than half the diameter of the cap so that the strength of said cap is not materially weakened, whereby said sealing flange may be broken at opposite points and the divided cap parts removed laterally without bending the portions of the sealing flange thereon, substantially as described.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
WILHELM EMMELIUS.
