BOTTLE-CLOSURE.

' Specification of Letters Patent.

Patented March 24, 1908.

To all whom it may concern:

Be it known that I, WILLIAM H. REID, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bottle-Closures, of which the following is a specification.

This invention relates especially to the closures for bottles used for delivering milk and cream.

The object of the invention is to provide a closure that can be cheapl manufactured by machinery out of materia like cardboard or pulp-board; which closure can be easily and efficiently ap lied to a bottle, es eciall when the botiile is entirely filled; an whic will be securely retained in position'and prevent spilling of the contents, and yet can be readily removed by simply pulling on the to member. 7

n the accompanying drawing representing embodiments of my invention, Figure 1 shows one form of cap conventionally in section, F 2 is a view of theca with the several disks slightly separate Fig. 3 represents a to view and Fig. 4 a bottom view, Fig. 5 s ows in section and Fig. 6 in side elevation the same cap on a larger scale. 7 shows enlar ed the position of the when flexed. ig. 8 shows conventionally in section the cap applied to a bottle. F' 9 shows conventiona 1% a cap formed of a feas number of disks. 10 is a view of another form of cap wit the members slightly separated. Fig. 11 shows the intermediate members of this cap. shows ig. 13 is a bottom plan view of the modification; and 14 shows conventionally a section on the line a:x ofv Fig. 13'.

The cap'comprises a top member or disk T of a size lar er than the o ning n in the mouth of the ottle D, so that the disk will rest on to of the bottle; and a series of smaller dis M. The bottle is shown as provided with an abutment b, and the distance from this abutment to the plane of the top of the bottle, that is, the plane of the bottom of the disk T, is, in the standard form of milk bottle about of an inch. The series of disks M are relatively very thin compared with their diameters, and are secured to the top disk T,and are ofa diameter to snugly fit. in the neck of the bottle being prefera ly of approximately the same'diameter. The

aggregate thickness of these su rposed disks is made equal to, or slightly ess than the said depth of the neck to the abutment, five of such disks are shown in Figs. 1 to 8. These disks are formed of a flexible fibrous material, such as cardboard or ulp-board. The to member is also prefera ly formed of simi ar material, that is preferably of a more tough and tenacious stuff; the other disks being of a poorer grade. These several members are not secured together throughout their entire adjoining area, but at their central portions only, whereby their marginal portions are left free to slide upon each other upon flexure of the disk, such as caused by pressure or draft at the central portion,

that will tend to dish the disks or bend tlTem' to a concave form.

Any suitable means can be employed to connect the disks whereby their marginal portions can slide upon each other, both in the insertion and removal of the cap; and whereby the marginal portions of the series of disks can separate during the removal that will facilitate the punching of the disks and their assemblage concentricall for the insertion of the fastening means. can be conveniently secured together b means of one or more wire staples S, as sue a fastening can be formed and applied by the ordina wire stitching, and hence form a part 0 the organized machine that constructs the cap. When such flexure is produced, the marginal portions of the disks will slide upon each other, and produce an effect similar tothat illustrated inFi 7; such as is produced when a ack of car are flexed the edge of each car projecting a very small distance beyond the adjacent cards and givin a somewhat serrated efiect.

' en the cap is inserted in the bottle, the

pressure thereon will cause it to react from the ti ht engagement with the bottle neck, and t e series of disk memberswill somewhat dish, tending to reduce their diameter and admit them into the neck. In the-0g eration of removi the cap by grasping t to disk at its IOJQCtlDg ma in, t e disks will flex and Wil be pulled out y the central connection, so that the disks will tend to separate at their margins. The pullinglbeing at the central portion, that portion will'be raised while the marginal portionbeingheld by friction of the bottle neck, and-the disks will dish and reduce their diameter, and will he disks be brought out one at a time with the edges separated; similar to the effect of flexing a pack of cards and passing the thumb over the edge to engage the cards at one end and release them successively. It is also found desirable to form the bottom disk B of a fibrous material that is tough and resilient, compared with the intermediate disksc, d, e and f, that are made of a lower grade and consequently cheaper material. This bottom'disk being of tougher material and conse uently offering more resistance to flexure, will serve to hold the cap more securely in position in the bottle mouth, against blows on the edge of the cap that would tend to dislodgeit, or to raise it a short distance. This bottom disk also acts in the nature of a protector for the other disks made of a Weaker material, and hence liable to unduly compress or bend upon insertion.

In Figs. 10 to 14 is shown a modified form of cap, in which the intermediate members between the top and bottom member or members are not circular, but poly onal and of the same size as the bottom disk. The a exes of the olygon lie in the peripher of t e series of isks below the top mem er, and the diameter of the polygon between 0 positeangles is equal to the diameter of tl e lower disks. The intermediate disks H are shown in Fig. 11 as hexagonal but may have a greater or less number of sides and angles with the apexes of the angle lying in the periphery of the series of dis s.. One or more, preferably two lower disks K are circular, corresponding to the lower disk B of the other form of cap, of a size to engage the bottle neck. The apexes h of the disk H coincide with the circumference of the disk K, that is, are in vertical alinement therewith, or in the cylindrical surface of the disks K. There are preferably two of the gollygon disks H interposed between the top is cated in Figs. 10 and 14. The operation of this form of closure when inserted .in the bottle is substantially similar to that of the closures above described herein; that is, the marginal portions of the four disks will slide on each other, both in the insertion and in the removal of the closure into and from the bottle. But between each apex of the intermediate disks, there will be a certain marginal s ace wherein the lower disks project eyon the intermediate disks forming a slight space. This will permit of a slight fiexure of the lower disks upward upon insertion and will facilitate the insertion of the closure where the bottle neck is of such a size as to cause a very tight fit of the closure. But the apexes of the intermediate disks extending to the periphery of the closure will cause the en agement of the neck b the intermediate disks as well as by the l dwer disks, and will result in each of the disks F and the two bottom disks K, as ind1- having an engagement with the wall of the bottle neck to assist in retaining the closure in the neck and resist its easy removal. These apexes will also revent the bottom disks frombeing unduy bent upward or dished.

Having thus described my invention, I claim:

1. A bottle closure comprising a diskadapted to engage the top of the bottle, and a series of flexible disks of fibrous material secured to the top disk and fitting into the vb'ottle neck, said series of disks being very thin relative to their diameters and secured at their central portions with the marginal portions free to slide upon each other and also to separate u on flexure.
