CLOSURE FOR CONTAINERS.

Application filed January 19, 1922. Serial No. 530,324.

To all whom it may concern:

Be it known that WESLEY W. MASON, a citizen of the United States, residing at Baltimore, in the State of Maryland, has invented certain newand useful Improvements in Closures for Containers, of which the following is a specification.

This invention has reference to closures for bottles, jars and like containers and has among other objects, to provide a closure formed of paper, orsuitable fibrous material, which maybe drawn down closely over and about the mouth of the container and having a skirt or flange to embrace the neck of the container and beheld in place by.

means of a metallic element carried by the flange of the closure prior to its attachment to the container. 1

Another object of the invention is to provide a paper .or fibrous closure whose skirt or flange carries a metallic element, ring or band, of vnon resilient metal which latter may be shortened by producing folds therein whereby to hold the closure in place on a container bandof non-resilient metal which latter may be contracted into locking engagement with the container whereby to hold the closure in place,

' With these, and other objects in view, the invention is illustrated in the accompanying drawings, wherein,--

Fig. 1. shows a jar to which a closure em-' bodying the invention is attached.

Fig, 2. illustrates in top view a cuppeddisk of paper or other fibrous material as in the ,first step in the production of one of my improved closures.

ig. 3. shows 'a cross-sectional detail. through the same.

Fig. ft. illustrates in top view a portion of the cupped disk with a ring or band in place thereon ready'to be secured therein,

Fig. 5. shows a cross-sectional detail through the same.

Fig. 6. illustrates, also-in top view .a portipn of the completed closure after the ring or band has been permanently secured around its marginal edge.

Fig. 7 shows a cross-sectional detail through the same- 1 Fig, 8. illustratesa vertical sectional detail through a bottle or jar-neck with the improved closure thereon.

Fig. 9. shows the neck in 'cross-section,- as the same would appear. if out on the line 9 9 of Fig. 8, but prior to the final operation of contracting the marginal edge. of the closure about the neck.

Fig. 10. illustrates a similar view after the marginal edge of the closure has been conltracted into locking engagement with the neo Fig. 11. shows a modified form of the invention wherein the paper or fibrous closure has been molded to engage a threaded bottleneck but with the ring or band enclosed in the marginal edge.

Fig. 12. illustrates another modified form of closure wherein the wired marginal edge is contracted beneath the locking shoulder of a well-known form of bottle-neck, and

Fig. 13. shows another modified form of closure embodying the invention wherein the marginal edge is contracted under a square shoulder on a jar-mouth. Byreference to F igs. 1 to 7 of the draw-- ings it will be noted that in the structure therein shown I first form a disk'15, from paper or other fibrous material whose marginal edge 16 has been turned up to produce a cup shape.

In this cupped disk I locate a wire, ring or band of non-resilient metal 17 which will retain any shape intowhich it may be bent or pinched, "and this wire, ring or band, is laid on the disk immediately around the upturned marginal edge 16 of the disk, as shown in Figs, land 5 of the drawings. I

' The up-turned edge of the disk is then folded down over the wire ring or band and said folded-down edge is permanently secured on-the surface of the disk, as shown at 18 in Figs. 6,- 7 and8 of the drawings, so that the metallic structure (wire, ring or band) will be completely enclosed and retained about the marginal edge of the disk and will thus become a permanentpart of the closure prior to the" attachment of the latter-to a container.-

The same procedure is followed in the forlip 21 of the bottle-mouth and this shoulder or undercut is utilized by me in efiecting attachment of the closure the container.

of' the container and draw it down around the exterior thereof and at the same time subject the material of the disk to the action of heat.

When the disk has been closely seated and its skirt or flange fitted about the neck of the closure the wired or enclosed metallic structure in themarginal edge of the closure will be contracted under the locking-shoulder or'undercut around the containerneck, and being of a non-resilient nature will remain in practically the condition into which it has been contracted so as to securely retain the closure in place.

In the case of a large closure as the same is drawn down and fitted about the containerneck, the marginal edge of the closure may be caused to assume or form a series of folds such as shown at 22 in Fig, 9 and these folds, when the contracting operation takes place, are bent in close about the closureneck and practically assume\ the form of fold shown at 23 in Fig. 10 of the drawing.

When the closure has been applied to a bottle or jar, as shown in Figs. 1 and 8, it will be noted that the entire mouth and upper end of the neck is enclosed and pro tected against contamination by cats or other animals.

In the structure shown in Figs. 12 and 13 the action in applying the closure is substantially the same as that set forth with respect to the bottle or jar shown in Figs. 1 and 8.

The bottle 24 of Fig. 12 has the ordinary crown locking-shoulder 25. under which the marginal edge metallic structure 17 is contracted, while in Fig. 13 the jar 26 has a squared locking-shoulder 27 under which the metallic structure 17 of the closure is contracted.

In Fig. 11, I show a bottle neck 28 whose exterior is provided with a coarse screwthread 29 and in this device the closure has been drawn down and compressed into engagement with the threads while the metallic structure 17 in the marginal edgeis contracted about the bottle neck below the screw-threads.

It will be noted that in each instance the closure when applied to a container has a covering portion which extends over the opening or mouthof the container; that it has a flange or skirt which depends below the bottle mouth and that the marginal edge of the closure carries an attached metal structure such as a wire ring or band which is capable of being contracted by forming folds therein, which folds effect a shortening of the metal structure which latter. will remain in the shortened condition so as to confine the marginal edge under a lockin shoulder on the container.

In practice the closures may have the form of a comparatively flat disk with the enclosed or attached metallic structure at the marginal edge or they may have a shape somewhat like the shape they assume when attached to a container,that is, with a depending skirt.

It should be understood that. in my invention the flange or skirt portion of the closure carries the metallic structure prior to the attachment of the closure to a container and that the flange or skirt material is foldedvin with the folds produced in the metallic structure so that both are'shortened in a circumferential direction to effect the contraction and close fit about the container.

Having described my invention, I claim,

1. A closure for containers comprising a non-resilient flexible covering to seat over the mouth of a container and extend downwardly from said mouth in the form of a skirt or flange and a foldable non-resilient metallic element attached to and carried by the said skirt or flange and foldable with said skirt or flange when the latter is contracted beneath thec-losure-mouth,the folding of the metallic element producing a shortening thereof, said metallic element having the characteristic of. retaining substantially the folded shape to which it is bent whereby its folds will hold the contracted skirt or flange in close engagement with the container below the mouth of the latter.

2. A closure for containers comprising a non-resilient flexible covering to seat over the mouth of a container and extend downwardly from said mouth in the form of a skirt or flange and a foldable non-resilient metallic ring attached to and carried by the said skirt or flange and foldable with said skirt or flange to contract the same beneath the closure-mouth,the fold produced in the ring effecting a reduction in the diameter thereof and the metallic ring having the characteristic of retaining substantially the folded shape to which it may be bent whereby to hold the skirt or flange of the closure in close engagement with the container.

3. A closure for containers comprising a non-resilient fibrous covering to seat over the mouth of a container and to extend down from said mouth. in the form of a flange or skirt said flange or skirt portion having a circumferential pocket formed therein and a non-resiliept metallic element confined interistic of retaining the fold made therein nently attached to and carried by the skirt to effect its shortening whereby to hold the or flange and folded with the skirt or flange fibrous flange in a contracted condition by to reduce the circumferential length of both means of the folds. and hold the flange in a folded and contract- 15 5 4.
