CONTAINER AND CLOSURE DEVICE THEREFOR Filed April 50, 1934 IN VEN TOR.

Jig-Z A TTORNEY Patented June 18, 1936 CONTR AND CLOSURE'DEVICE THEREFOR Herbert A. Barnby, Toledo, Ohio, assignor to Owens-Illinois Glass Company, a corporation of Ohio Application April 30, 1934, Sierial No. 723,093

. 6 Claims. (a. are -37) tion and a depending skirt attached thereto,

the said cover portion and skirt being made in separate pieces. The skirt comprises a sheet metal strip bent to cylindrical form and having its ends united by a vertical seam, the container being provided with a groove or recess to receive the seam.

An object of the invention is to provide a practical construction of the character indicated including means by which the closure device is effectively secured to the container in a manner to prevent it from becoming loosened or turning on the container.

Other objects of the invention will appear hereinafter.

In the accompanying drawing:

Fig. 1 is an elevation view of a container with a closure device or fitment in position thereon.

Fig. 2 is a sectional elevation of the same.

Fig. 3 is a fragmentary sectional elevation'on a larger scale showing the closure device on the container before being forced down to its final position.

Fig. 4 is a section at the line IV-IV on Fig. 2.

The container 5 as herein shown is a glass jar of substantially cylindrical formation. The closure device which is preferably made of sheet metal, comprises a top cover portion 6 and a depending skirt 1 made in a separate piece. The circular top 6 is upwardly convex and has a downwardly and outwardly inclined annular flange portion 8, the outer margin 9 of which is turned upward, forming with said flange portion an annular recess. The skirt 1 is made of a single strip of sheet metal curved to cylindrical form. The ends of the strip are bent back upon themselves to form hooks which are interlocked, thus forming a vertical seam ill. The upper portion of the skirt I is curled to form a bead II. This bead projects outwardly beyond the body of the skirt 1 and is curled inwardly and downwardly with the marginal portion l2 extending downward into the annular recess formed by the parts 8 and 9 of the cover portion or cap 6. The margin 9 of the cap is clamped within the bead, thereby securely uniting the cap 6 and variations in the sizes of different jars.

skirt 8. An auxiliary cover piece or cap It overlies the cap 6 and is of the-same general conformation. The margin of the cap it is rolled over the bead Ii. This construction permits the cap i i'to'be rotated to bring into register openings l6 and ll formed in the caps M and 6, re-

spectively, permitting the contents of the jar to be dispensed.

The jar is formed with a vertical channel or groove 2?! providing a recess to receive the seam m, thereby providing means for positively holding the skirt i against rotation relative to the jar and also permitting the seam it to be formed within the outline of the skirt. In this manner the skirt may be made to adhere closely to the surface of the jar throughout its entire circumference, also presenting a smooth exterior surface.

The jar is formed with an annular recess I8 in its exterior surface. the lower end of said said corrugations terminating at the shoulder i9.

The upper or neck portion of the jar has its exterior surface downwardly and outwardly tapered as shown at 26. The tapered portion may extend from the top surface of the jar or from the recess 26 downward to the recess It. This tapered construction facilitates the assembling of the jar and-closure device and is particularly adapted for obtaining a tight fit of the skirt l on the container. The closure device and container may be assembled by passing the same under a corking wheel by which the skirt is driven downward over the tapered portion of the jar until it contacts with the shoulder it. The construction of the seam to is such that it permits the required expansion of the skirt as it moves downward into position. The seam also permits the skirt to accommodate itself to the slight As a further means of securing the closure device in position, a cement or glue is used which may cover the contacting surfaces ofthe' jar and skirt. The cooperating seam l0 and groove 21 serve to posi tively prevent any rotative movement of the attachment which would break the cement seal or dislodge the attachment. If desired, a ring gasket 22 made of rubber composition or the like may be used to form a tight seal between the lip of the jar and the cap.

Modifications may be resorted to within the spirit and scope of my invention.

I claim:

1. A closure device for a jar or other container, comprising a substantially circular top cover portion and a depending skirt, said top cover portion being formed with an annular upwardly facing recess forming the periphery of said cover portion, said skirt having its upper margin rolled inwardly to form a bead, the edge of said head being seated in said annular recess and the margin of the cover portion being clamped in said bead, and an auxiliary cover or cap overlying said top cover portion and having its peripheral margin rolled over said bead for frictionally holding said auxiliary cover in position and permitting rotative movement thereof relative to said top cover portion, said cap and top cover portion having openings therethrough brought into and out of register by rotative movement of the said cap.

2. The combination of a container, and a closure device therefor comprising a top cover portion and a depending skirt fitted over the upper portion of the side walls of the container, the latter formed with a vertically disposed recess in its outer surface, said skirt consisting of a strip of sheet material curved to conform to the shape of the container and having its ends united in a vertically disposed seam seated in said recess, the surface of the container with which the skirt engages being slightly tapered or flared downwardly and outwardly.

3. The combination of a container, and a closure device therefor comprising a top cover portion and a depending skirt fitted over the upper portion of the side walls of the container, the latter formed with a vertically disposed recess in its outer surface, said skirt consisting of a strip of sheet material curved to conform to the shape of the container and having its ends united in a vertically disposed seam seated in said recess, the portion of said container surrounded by said skirt being flared downwardly and outwardly and of smaller exterior diameter than that of the adjoining portion therebeneath, said reduced portion providing a shoulder against which the lower edge of the skirt engages.

4. The combination of a container, and a closure device therefor comprising a top cover portion and a depending skirt fitted over the upper portion of the side walls of the container, the latter formed with a vertically disposed recess in its outer surface, said skirt consisting of a strip adjoining portion therebeneath, said reduced.

portion providing a shoulder against which the lower edge of the skirt engages, the exterior surface of said skirt being flush with the exterior surface of ,the container therebeneath at said shoulder.

5. The combination of a container and a closure device therefor comprising a top cover portion and a depending skirt fitted over the upper portion of the side walls of the container, said top portion including a perforate non-rotatable disk attached to said skirt and a perforate rotatable disk overlying the non-rotatable disk and rotatively engaged with said skirt, said container formed with a vertically disposed recess in its outer surface, said skirt consisting of a strip of sheet metal curved to conform to the shape of the container and having its ends united in a vertically disposed seam seated in said recess, the portion of said container surrounded by said skirt being flared downwardly and outwardly and of smaller exterior diameter than that of the said subjacent portions, said reduced portion providing a shoulder against which the lower edge ofthe skirt engages.
