CLOSVURE CAP ,Filed Feb. z5, 1940' y Patented Nov. 18., 14941 Howard F. Reichenbach, Waterbury, Conn., assignor to Chasev Brass & Copper Co. Incorporated, Waterbury, Conn., a. corporation Application February 23, 1940, serial No. 320,243

4 Claims.

The present invention relates to improvements in closure caps for threaded application to bottles, cans, and other containers.

One of the objects of the present invention is to provide a closure cap characterized by a superior degree of neatness and attractiveness of appearance.

Another object-of the present* invention is to provide a superior closure cap combining low cost for manufacture with adequate strength and attractiveness of appearance.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosurey which are novel over the prior art and which are not-y claimed in any separate application.

In the accompanying drawing, in which certain modes of carrying out the present invention are shown for illustrative purposes:

Fig. 1 is a View in side elevation of a closure cap embodying the present invention;

Fig. 2 is an underside View thereof;

Fig. 3 is a vertical central sectional view taken on the line 3-3 of Fig. 1, but on a larger scale;

Fig. 4 is a transverse sectional View taken on the line 4 4 of Fig. 3;

Fig. 5 is a vieW partly in side elevation and partly in vertical central section of the outer shell on the same scale as Figs. 3 and 4;

Fig. 6 is an underside view thereof on the scale of Figs. 1 and 2;

Fig. 'l is a View partly in side elevation and partly in vertical central section of the inner shell on the scale of Figs. 3, 4 and 5; and

Fig. 8 is a top or plan view thereof on the scale of Figs. 1, 2 and 6.

The particular closure cap herein chosen for the purposes of illustrating the present invention, comprises an outer shell generally designated by the reference character I0 and an inner shell generally designated by the reference character II.

The outer shell IIJ above referred to, has, in the particular closure cap shown, a substantiallyspherical, hollow body-portion I2 from the lower edge of which inwardly extends an integral substantially-horizontal flange I3. Formed integral with the inner portion of the flange I3 just referred to, is a substantially cylindrically-contoured neck I4 extending downwardly from the said flange I3 in parallelism with the vertical central axis of the outer shell I0. As will be noted by reference to the drawing, the neck I4 is smaller in diameter than the diameter of the body-portion I2 for purposes as will hereinafter appear.

The inner shell II above referred to is of inverted cup-shaped form and includes a substantiallyy cylindrically-contoured neck I5 sized and shaped exteriorly to be snugly received with a force-fit into the interior of the neck I4 ofthe outer shell I0. Formed integrallyr with the lower end of the neck I5 of the inner shell II, is a reversely-bent nishing-skirt I6 sloping upwardly and outwardly and preferably snugly engaging they outer shell I0 at a pointv adjacent the juncture of the body-portion I2 and theflange, I3 thereof, as is especially well shownv inA Fig. 3. The finishing-skirt I6, just referred to, is preferably spherically contoured to complement the substantially-spherical contour of the body-por- .tion I2 of the outer shell I0.

The inner shell I I also includes a horizontallyextending flange I1 integrally united at its outer portion with the upper end of the neck I5 and integrally joined at its inner portion With the lower end of the hollow body-portion I8 of the inner shell II. The periphery of the said bodyportion I8 is rolled or otherwise suitably formed to provide threads I9 for engagement with the threaded terminal of a bottle or other container.

At the upper end of its body-portion I8 the inner shell Il is formed with an integral substantially-flat enclor top-wall 2l) providing a seat for a sealing gasket 2| which latter is designed and adapted to be seated against the upper surface of the neck of a bottle or other container to provide a fluid-tight seal.

By constructing and arranging the respective outer shell I0 and inner shell I I as shown, a neat, attractive and rugged closure cap is provided which may be manufactured economically.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristic of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.

I claim:

1. A closure cap comprising: an outer shell having a substantially-spherically-contoured body-portion and also having at its lower end a neck-portion having a diameter smaller than the diameter of the said body-portion and constructed and arranged to receive a cylindrically-contoured portion of an inner shell; and an inner shell of inverted substantially cup-shaped form and including a threaded portion extending upwardly into the interior of the spherically-contoured body-portion of the said outer shell, a neck-portion of substantially-cylindrica1 form snugly tting within the cylindrically-contoured neck-portion of the said outer shell, the said inner shell also having a nishing-skirt of substantially-spherical exterior contour and formed integral with and reversely extending from the lower end of the neck-portion of the said inner shell and encircling and substantially concealing the reduced-diametered cylindrical neck of the said outer shell, the said finishing-skirt compleinenting and forming a continuation of the substantially-spherical outer contour of the .bodyportion of the said outer shell.

2. A closure capcomprising: an outer shell having asubstantially-spherically-contoured body-portion and also having at its lower end a neck-portion having a diameter smaller than the diameter of the said body-portion and constructed and arranged to receive a cylindricallycontoured portion of an inner shell; and an inner shell of inverted substantially cup-shaped form and including a threaded portion extending upwardly into the interior of the sphericallycontoured body-portion of the said outer shell, a neck-portion of substantially-cylindrical form having a larger diameter than the said threaded portion and snugly fitting within the cylindrically-contoured neck-portion of the said outer shell, the said inner shell also having a nishing-skirt of substantially-spherical exterior contour and formed integral with and reversely extending from the lower end of the relatively large-diametered neck-portion of the said inner shell and encircling and substantially concealing the reduced diametered cylindrical neck of the said outer shell, the said finishing-skirt `complementing and forming a continuation of the substantially-spherical outer contour of the body-portion of the said outer shell.

3. A closure cap having an ornamental outer surface and comprising: an outer shell providing the major portion of said ornamental outer surface and including at its lower end an inwardlyextending flange, and a substantially-cylindrical neck-portion depending from the inner portion of said ange; and an inner shell of inverted sub- Y stantially cup-shaped form including a threaded portion extending upwardly into the interior of said outer shell, a substantially-cylindrical neckportion fitting and secured in the interior of the cylindricalv neck-portion of said outer shell, and

ya finishing-skirt integral with the lower end of the neck-portion of said inner shell and surrounding, and iiaring upwardly and outwardly away from,` the cylindrical neck-portion of said outer shell to form the lower part of said ornamental outei' surface.

, 4. A closure cap having an ornamental outer surface and comprising: an outer shell providing the major portion of said ornamental outer surface and including at its lower end an inwardlyextending flange, and a substantially-cylindrical neck-portion depending from the inner portion of vsaid ange; and an inner shell of inverted substantially cup-shaped form including a threaded portion extending upwardly into the interior of said outer shell, a substantially-cylindrical neck-portion fitting and secured in the interior of the cylindrical neck-portion of said outer shellv by a force fit, and a finishing-skirt integral with the lower end of the neck-portion of said inner shell and surrounding, and flaring upwardly and outwardly away from, the cylindrical neck-portion of said outer shell to form the lower part of said ornamental outer surface.
