William J. Keith, Brookline, Mass., assigner to Kep-Ark Inc., Boston, Mass., a corporation of Massachusetts Application October 24, 1934, Serial No. 749,738
(Cl. 21S- 43) 7 Claims.
My invention relates to closures for bottles, iiasks, jars, and other containers.
'Threads upon the containers are not of .uniform shape or smoothness throughout their respectivey lengths but contain minor defects and irregularities. Therefore in the manufacture of closures for containers it has been. found that the former are .'endered inadequate or useless because their imperfect t or interengagement with the threaded portions of the containers.
An object 4of the present invention is to insure a perfect t of the closure upon the container regardless of the structural inequalities of the latter.
Additional objects of the invention are to prevent the accidental escape of the filler disk, and to insure an air tight seal between the latter and the guide ring or cylinder of the closure at their junction with each other, whereby the ingress of air to, or escape of aroma from, the container is insured.
Further objects of invention are security of the assembled parts of the closure, speed and inexpensiveness of construction, and theiavoidance Y of exterior disgurement of the closure in effecting these purposes. Y
With the above and other objects and advantageous features in View, the invention consists of an arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawing,.and more specically dened in the claims appended thereto. Referring tothe drawing,
Figure 1 is a side elevation of a container with my novel closure therefor engaged therewith,
Figure 2, a top plan view of the closure,
Figure 3, an enlarged diametrical section of the same,
Figure 4, a fragmentary side elevation of the container -showing in diametrical section the closure in locked engagement therewith,
Figure 5, a front elevation of the guide ring,
Figure A6, a fragmentary plan view of the front portion of-the ring,
Figure 7, a detailed perspective view of the disk after assemblage of the parts, and
Figure 8, a diametrical section of a modied form of my closure.
As shown in the drawing, I0 represents a container in the form of a bottle including a body portion.V II and a neck portion I2 provided with an external helical rib or screw thread' I3. As
illustrated the thread is continuous in form, but
this is not essential.
'I'he closure I 5 for the container orice includes I broad guide ring 20 of thin resilient metal wh`ose a cap I 6 drawn up, in this case, from thin metal comprising a circular convex top II and a cylindrical side or skirt I8. f
Mounted within the cap is a transversely split 5 end portions 2i overlap each other. In detail the ring includes an intermediate or body portion 22, a top edge portion 23 comprising an annular series of flutes 24, and an outwardly offset base portion 25 including a laterally extending shoulder 26 terminating in a depending ilange 21.
In assembling the cap and `ring an originally downwardly extending portion of the skirt is folded inwardly transversely'of the flange 2'I and against the inner face of the latter forming the lap 29 and fold 30 and forms a portion of the cap I6. The upper edge of the lap engages the lower face of the shoulder 26. During this fold ing step the upperedge of the ring was thrust against an intermediate portion of the lower face of an originally flat circular filler disk 3|, abutting against the cap top I1, with sufficient force to radially bend the annular marginal portion 32 of said disk at an incline relatively to the horizontal plane of the upper edge of the ring. The 25 portion 32 cooperates with said upper edge of the ring to increase the sealing efliciency of the structure. 'I'he disk is composed of pulp-board, cork, felt, or other suitable material.
'Ihe body portion of the guide ring includes a guide element consisting of a helical rib or thread 34 adapted to slidably engage the rib or thread I3 of the container. The thread 34 as herein shown is of the interrupted type, but such type is not exclusive of a continuous thread, nor exclusive of any other spirally disposed series of units adapted to contact with the thread I3.
The ring, which is of thin resilient metal, is sufficientlyI yielding to allow for the inequalities of surface or dimensions of the thread of the container, or of the threads of various containers; the space between the body of the ring and the' skirt of the cap facilitating such expansion.
The mutually overlapping flutes upon ,the end portions of the ring suiiiciently interlock to prevent excessive expansion oi the upper margin of the ring under unusual strain. The iluted character of the upper edge of the ring also extends the area of contact of the edge with the iiller disk, which thus also contributes to the effective retention of the disk in place.
The shell and enclosed ring are capablel of speedy mechanical formation `and assemblage, and the completed closure shows\ no external disfigurement.
The structure of the cap 36, shown in Figure 8, differs from that'shown in Figure 3 in that the top 31 is fiat rather than convex, and the circular ller disk 38 is perfectly flat throughout its entire area.
lI claim:-
1. A closure comprising a cap having top and skirt portions, a filler disk within the cap, and a split internal guide ring provided with overlapping ends and secured within the skirt por- I tion with its upper edge bearing against the ller disk, said guide ring having its major portion including its upper edgev portion spaced' from the skirt portion of the cap for expansion relative thereto, the overlapping ends of the guide ring presenting a continuous upper edge to the disk.
2. In a closure of the character described, a cap including a top, a skirt, and an annular fold on the skirt, a ller disk contacting with'the top, and an internal guide ring comprising a body portion spaced from the skirt, an offset lower portion engaged by the fold, and annularly disposed utes upon the upper portion of the body engaging the disk.
3. Ina closure of the character described, a cap including a top, a skirt, and a fold upon the skirt, a ller disk contacting with the top, and a transversely split guide ring including overlapping end portions, and comprising a, body portion spaced from the skirt, an offset lower portion engaged by the fold, and flutes upon said overlapping portions engaging the disk.
4. In a closure of the character described, a cap including a convex top, a skirt, and an inwardly directed fold upon the bottom of the skirt, a filler disk provided with a downwardly inclined peripheral margin abutting against said top, a transversely split guide ring engaged at the lower edge by the fold and provided in its upper edge with annularly disposed flutes engaging an intermediate portion ot the disk adjacent the inclined margin.
5. In a closure of the character described, a cap including a top and a skirt, a filler disk engaging the top, a guide ring secured within the skirt, and ilutes at the top of the guide ring having the ends thereof engaging the disk.
6. A closure comprising a cap having top and skirt portions, and an internal guide ring secured to the skirt at its lower edge and having a body portion thereof spaced from the skirt portion and being transversely split with overlapping end portions arranged for yieldable expansion of said body portion relative to the skirt portion, said overlapping end portions having intertting utes therein arranged to interlock and prevent excessive expansion of the ring.
'7.l A closure comprising a cap having top and skirt portions, the skirt portion having an annular internal fold at the lower edge thereof, a ller disk bearing against the under side of the top portion, and an internal guide ring having a threaded body portion spaced -from the skirt portion, said guide ring having an oiset lower portion engaged by the fold, and having overlapping ends arranged for yieldable expansion of the body portion relative to the skirt portion without separation of the ends, the upper edge portion of the guide ring having upwardly extending flutes therein the ends of which engage an intermediate portion of the ller disk.
