8 Claims.

This invention relates to caps adaptable for sealing containers such as milk bottles, jars, and

other types ordinarily used in packing and vend-v ing jams, peanut butter, or other commodities. It has for its objects to provide sealing means, inexpensive to manufacture and eflicient in use; to provide a sealing means whichwill, in addition to effecting a perfect sealing, at the same time provide protection for the exterior of the container at and near the point of sealing, so that the said adjacent exterior may be protected from any contact with foreign substances; to provide a sealing means which is practically impossible to remove without leaving visible evidence of the removal, yet which can be easily and readily removed by hand without the use of tools or other implements; to provide a sealing means of maximum effectiveness in the first instance, yet is impossible to remove without showing visible evidences of its first removal; to provide a sealing means which is usable and effective with or without an inner gasket; to provide a sealing means which will meet the requirements of the most exacting board of health regulations; to provide a sealing means originally constructed in a. plurality of parts, but which, in assembled form, become integral; to insure effective means against the refilling of original containers without visible evidence of such refilling; to provide a, seal- 9 ing part, sufliciently sized to well cover and pro tect the container opening, thereby afiording ample retaining space upon which to securely fasten the plural portion of the complete sealing means;

to provide a sealing member or disc, having therein on a line parallel to its outer circumference, a

series of triangular cuts, forming, but not detaching, a series of fan-shaped pieces which may in turn be folded in the direction of the outer circumference of the sealing disc, so as to render the disc of major bulk and thickness adjacent its exterior circumference, and of a lesser and corresponding bulk at points within and parallel to said exterior circumference, all for the. purpose of rendering of lesser thickness, that portion of the disc which contacts with the container at its greatest circumference immediately adjacent the containers opening, and of greater thickness at that portion of the disc which contacts the container on the side of said greatest circumference which is positioned away from the containers opening; to provide effective locking means for securing the said disc in position on the container; to number said cuts and fan-shaped pieces in proportion to the size of the disc, so as to remove '55 a substantial portion of the disc at its out out 1932, Serial No. 62am area and fold same onto the exterior of the disc adjacent its outer circumference, and thereby substantially increase the thickness of said disc at said outer circumference; to provide an exterior ring member of diameter substantially equal to the distance between one of said openings in said disc, and the opening farthest therefrom on the opposite side of the disc; to provide an exterior ring sized to fit snugly over the edges of the disc 'as they envelope the sides of the container adjacent its opening, adaptable to function so as to force said fan-shaped pieces in the direction of the outer circumference, and onto that portion of the disc adjacent said outer circumference;'to thereby securely anchor the disc in position upon and about the opening of the container by sheer force of its thickened outer circumferenceconflned within said ring; to provide a mode of construction and application which produces a significant and outstanding drum-like tautness at that portion of the disc which covers the container opening; to provide a construction and method of application, the various steps of which all function to co-operate to an effective and'finished result in an apparent and integral merger; to insure a unit construction by the application of a suitable adhesive to the parts of the vice, rendering it unsuitable for further use; to

provide a seal of maximum eiilciency and attractiveness at a minimum cost of material; to materially increase the measure of sealer accomplishment; to provide a sealer both neat and close fitting, eliminating elements such as the outstandirrg and overhanging parts which easily become soiled and are otherwise objectionable; to provide a sealer of major attractiveness which readily blends with desirable color effects, in lettering an ornamental design, for advertising purposes; and to provide the various otheradvantages and results made evident from the following specification.

I accomplish the objects of my invention by providing a member or disc, having therein on a line parallel to its outer circumference, a series of cuts, forming, but not detaching, a series of fanshaped pieces which may in turn be folded in the direction of the outer circumference of the sealing disc,- So as to render the disc of major bulk and thickness adjacent its exterior circumference,

and of greater thickness at that portion of the disc which contacts the container on the side of I said greatestcircumference which is positioned away from the containers opening. I then provide an exterior ring sized to fit snugly over the edges of the disc as they envelop the sides of the container adjacent its opening, adaptable to function so as to force said fan-shaped pieces in the direction of the outer circumference, and

onto that portion of the disc adjacent said outer circumference. Optionally, I apply a suitable adhesive to the parts of the device where they contact parallel to the said exterior circumference of said disc. The application of such adhesive at said points, materially contributes to the impossibility of removing the device without visible evidence of such removal. The sealing means herein described is applicable with or without an inner gasket, such use being optional. Said outer sealing ring is provided on its-exterior with an incision which weakens its structure thereabouts so that a tearing pressure there applied, results in its removal and partial ruin, rendering it unsuitable for further use.

The series of-fan-shaped pieces referred to may I optionally be folded inwardly or outwardly onto the surface of the disc adjacent its outer circumference. That portion of the disc adjacent its outer circumference may optionally be fluted to better facilitate itscloser formation to the sides of the container adjacent its opening.

. to the exact details of construction herein set forth, but desire to avail myself of such variations the scope of and modifications as come within the appended claims.

Referring to the accompanying drawing which forms a part of this specification and in which similar letters of reference refer to similar parts throughout the various views, Figure 1 shows my improved device as positioned on-the top of a milk bottle. Figure 2 shows .a half section of the bottle and cap shown in Figure 1. Figure 3 shows --Referring again to the drawing, A shows the disc designated as E.

container. 13 shows the sealing disc. C shows the exterior ring. D shows the fan-shaped pieces, cut from the sealing disc and folded onto and upon that portion of the disc adjacent its outer ciroumference as shown in Figures 5 and 6, said fanshaped pieces being cut from that portion of the During the process of application, the sealing disc B, first prepared as shown in 'Figure 6, is

shaped by pressure into the form shown in Figure 5, with the fan-shaped pieces D, extending downwardly as shown in the direction of the outercircumference of: the disc; Theexterior ring adhesive acts to make the sealing disc and outer ring integral.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States of America:
