CONTAINER CLOSURE Filed April 12, 1946 E li INVEN TOR.
Patented Dec. 13, 1949 2,490,191 CONTAINER CLOSURE George C. Erb, Forest Hills West, N. Y., assignor to American Can Company, New York, N. Y., a corporation of New Jersey Application April 12, 1946, Serial No. 661,753
. 4 Claims. (Cl. 215-46) This invention relates to metallic closures for containers and has particular reference to a sealing type cap formed with an integral concentric hollow pull ring which normally surrounds the cap when it is in sealed position, the ring being adapted for easy removal of the cap when opening the container.
The-closure disclosed herein is also shown in my application, Serial No. 661,754, filed April 12, 1946, for Container closure manufacture. This application resulted in Patent No. 2,443,185, which issued June 15, 1948.
An object of the invention is the provision of a. metallic crown cap or crimped closure for containers adapted to hold carbonated gaseous liquids such as beer or the like wherein a hollow pull ring is provided integral-with and surrounding a crown or cap closure, which closure may be applied readily to hermetically seal such a container for preserving its contents and which cap may be removed easily by merely lifting and withdrawing the pull ring to eflect opening of the container.
Another object of the invention is the provision of a closure of the character described having a curled concentric section which is joined integrally to the cap in a curved bridge hemmed at its outer periphery and merging into a hollow pull ring surrounding the cap and disposed below it when in sealed position on the container, which ring upon being pulled up by hand effects removal of the cap for opening the container.
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings,
discloses a preferred embodiment thereof.
Referring to the drawings:
Figure 1 is a top plan view of a crown cap closure having an integral hollow pull ring and embodying the present invention;
Fig. 2 is a side elevation of the cap closure and pull ring shown in Fig. 1;
Fig. 3 is a sectional view of the closure illustrated in Figs. 1 and 2, in a sealed position on the mouth of a container; and
Fig. 4 is a side elevation showing the pull ring in a raised position as an incident to removing the cap in opening the container.
As a preferred embodiment of the invention the drawings illustrate an easy removable crown sealing cap A having a hollow pull ring B formed integral therewith. Such a ring preferably is connected to the cap A by a curved bridge C (Fig. 1) which extends, as a skirted section ll,
from a depending crown wall l2 for securing the closure to a container D.
The closure of the instant invention is formed from a metallic disk which has an arcuate sec: tion cut therefrom to provide a crescent opening I3 between the cap A and the ring B. This permits the manufacture of the cap A in a conventional manner having its depending crown wall l2 sloping downwardly and outwardly, as best illustrated in Fig. 2. Figs. 1 and 2 show the crowned wall l2 prior to being secured onto the container.
The cap A also is formed with a central panel l4 (Figs. 1 and 3) which defines an annular encircling channel I5. It is into this channel that a suitable gasket or sealing compound I6 is positioned toefiect a hermetic seal for-the cap when it is applied onto a container.
The curved bridge 0 extends downwardly and outwardly from the skirted section I I (Fig. 3) and merges into a flange IT. This flange is in a plane parallel to and disposed below the plane of the panel H of the cap A when the latter is in sealed position on the container. Flange I1 is shown as resting against a body wall l8 of the container D but this particular position is not necessary as the flange may be spaced away from the wall l8 if desired.
The flange ll of the bridge C terminates at its outer periphery in a hemmed edge 22 (Figs. 1 and 3). This hemmed edge merges into the hollow pull ring B at its opposite ends as at 23, 24.
The hollow pull ring B includes an inwardly curled peripheral edge 25 and an outwardly curled peripheral edge 26. The terminal ends 23, 24 of the hem 22 merge into the inwardly curled peripheral edge 25. The outwardly curled peripheral edge 26 terminates in angularly disposed hemmed edges 21, 28 at the curved bridge C. The curled edges 25, 26 thus constitute a smooth hollow ring surrounding the cap A when the closure is in sealed position on the container D.
Referring to Fig. 3 of the drawing, there is shown a closure of the instant invent on in sealed position on a pouring mouth E of the container D. Such a mouth includes an annular wall 32 which encircles a fillingand dispensing opening 33. Wall 32 has an enlarged annular edge or rim 34 on which the sealing cap A is secured.
Removal of the cap A in opening the container is effected first by lifting the hollow pull ring B upwardly from the position shown in Fig. 3 to that illustrated in Fig. 4. From this position the ring may be pulled away from the container to withdraw the sealing cap A from its sealed position. This uncovers the pouring mouth E of the container. This withdrawing step is done easily by hand without fear of injury and without the use of any opening tools.
It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the -form hereinbefore described being merely a preferred embodiment thereof.
I claim:
1. An easily removable closure for a container, comprising a sealing cap having an uninterrupted skirted crown sealing cap wall for attachment to the container, a deformable integral bridge portion extending outwardly from a minor portion of the circumference of said sealing wall cap being spaced from said sealing wall to provide clearance for engagement with the ring to lift it by bending of said extended edge of the closure wall incident to removal of the cap from said container.
3. An easily removable closure for a container, said closure comprising a sealing member for the container, a ring member, and a bridge portion uniting said sealing and ring memberasaid ring having curled edges merging with said bridge portion in hemmed edges, said bridge portion .being deformable adjacent said hemmed edges when said ring is raised for the purpose of removing said sealing member from the container.
4. -An easily removable cap and pull ring of a continuous formed circular sheet, comprising a cap having a peripheral flange for sealing a container outlet, and a pull ring surrounding said peripheral flange and merging with said flange along a minor portion of the inner margin of said ring in a radially extending bridge, and a radially outwardly bent edge extending-around spaced from said sealing wall to provide clear-1 ance for engagement with the ring to lift it and curled edge, said ring inner edge merging with said extended edge of the closure wall in substantially radially extending hemmed edges and said ring outer ,edge'hierging with said extended edge of the closure wall in a peripheral hemmed edge, said pull ring on the opposite side of said v the remainder of said inner margin of the pull ring and spaced from said peripheral flange to provide a finger hold section to facilitate removal of said cap from the container outlet.
