SEALING-DISK.
Specification of Letters Patent.
Patented July 18, 1916.
To all whom it may concern:
' Be it known that I, GEORGE F. KNOX, a subject of the King of England, and'resident of Louisville, in the county of Jefferson and State of Kentucky, have invented oer tain new and useful Improvements in Sealing-Disks; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention refers to sealing disks for crown caps especially adapted to be used in connection with the necks of bottles having double seated or grooved mouths, such as described iii a patent issued to me February 23, 1915, No. 1129578.
The object of my invention is to provide a simple, economical and effective disk of composite material embodying an outer ring composed preferably of some spongy substance and an inner core of tough pliable fibrous substance, each unit of which is utilized as a seating medium in connection with corresponding high surfaces of a grooved mouth bottle or other container, as
' described in my pate'nt'referred to.
Heretofore, so far as I am aware, sealing disks used in connection with crowned caps, have been made from various materials of like consistency throughout, some of which are composed of natural cork cut into the desired dimensions. Others have employed fibrous material formed into layers which material is treated with paraffin to render the same impervious to moisture. The ma terial more generally used consists of granulated cork impregnated with some adhesive vehicle molded and pressed'to the desired shape. Practice has demonstrated that, while the natural cork is desirable due to the fact of its resilient properties, it is not entirely practical for the reason that the natural porous body when out into disks develops leak-holes or defective crevices whereby an imperfect seal will result. A composition fibrous disk'is objectionable for the reason that it has not sufiicient pliability or resiliency to fill 'up small crevices and form aperfect union under allconditions. Hence j the composition cork disk formed from" the granulated material is preferable for a erfect seal, but that portion of the cork which is subjected to the influence of the liquid contents of the container becomes saturatcd and will disintegrate or slough ofl", whereby the product is contaminated.
Hence itis the'purpose of my present invention to overcome the objectionable features of a one-piece sealing disk, which objectlons are overcome by employing a composite disk, as' stated, with'a tough fibrous core and an outer ring of spongy material preferably. cork. The tough fibrous material is thus directly subjected to the contents of the'bottle and will resist moisture or chemical action. The outer edges of the core member will form one seating surface, while the spongy-ring will form a second seating surface, thus insuring a double contact and owing"to the resiliency of the ring member, when pressure is placed upon the disk the particles composing said ring member will fill up the crevices at the mouth of the vesselto insure a perfect seal."
With the above objects in view the invention consists in certain peculiarities of construction and combination of parts asset forth hereinafter with reference to the'accompanying drawings and subsequently claimed.
In the drawings Figure 1 represents a sectional elevation of a bottle neck fitted with a crown cap carrying a disk embodying the features of my invention, one-half of said disk and cap being shown fitted to the mouth of the vessel preparatory to being closed thereover, while the other half illustrates the bottle mouth and cap after the seal is effected; Fig. 2 represents a similar view of another form of disk wherein the core portion is beveled in the opposite direction from that shown in Fig. 1, and Fig. 3, still another form of my invention wherein the ring and core sections of different materials 'are molded into a homogeneous body.
Referring by characters tothe drawings,
'A, represents the neck of a bottle, the mouth of which is formed with an intermediate groove'whereby an inner seating face a, and
an; outer seating face a is formed. A mering section is of any soft spongy material 1 forced upon the beveled outer edge of the core sectlons, whereby a unitary disk is formed, which disk is then inserted and secured within the cap in the ordinary manner.
In some instances fibrous material from .which the core section 1 of the disk is stamped, may have one face thereof plated with metal, which plated surface would be presented to the liquid when the-cap serves as a closure, whereby said'cap' offers a surface to resist gases or detrimental chemical results of action of certain liquids. be seen by referring to Fig. 1, that the outer edge of the core section I rests upon one seat of the vessel mouth and the cork section rests upon the outer seat of said mouth, the groove being approximately between the point of 'joinder of the disk elements. In this type of disk where the contemporary beveled faces are flared outwardly, the ring 2 forms the locking 'element and when said ring is pressed to effect a seal and subjected" to a steaming process, its particles are free to expand in all directions and fill up the various interstices. Hence, as shown to the right in Fi l, the first sealing seat is effected between the core element and the high face a of the bottle, while the ring not only forms a seat in connection with the high face a of the bottle but expands into the groove between the high faces and insures a perfect union independent of the first seal mentioned.
Fig. 2 shows the contemporary beveled union :1: between the disk elements as converging toward the outer face of the cap and this type of disk may.-in some instances, be preferable. The core section 1 in the form of disk shown in Fig. 2, in place of being manufactured from laminated fibers, is shown as a solid body and when the disk is finally seated, a double seat is effected by swelling of both members, attention being called to the fact that the beveled line 00 is intermediate of the high seating face a of the bottle mouth, whereby; the materials It will 7 same result may be obtained by molding the disk in one piece having a core 1"- of tgugh .plastic or fibrous material and an outer'ring section 2" of some spongy material, which materials are merged at the line 3 one within the other to form" a homogeneous mass, the said line of commingling of the different materials being at the point of the groove upon the upper surface of the mouth of the bottle. It is also within the scope of my invention to dispense with the beveled union between the ring section and core section and use a straight inner edged ring, which may be matched with the corresponding straight annular surface of the core section.
It is obvious that, in some instances, the fibrous material constituting the core section 1 may be treated with paraffin or other liquid-proofing material or the sealing disk as a whole may be so treated before or after completion.
I claim:
1. A composite sealing disk comprising a core section formed from pliable material substantially impervious to action of material to be sealed, and a ring section fitted to the edge of the core section composed of material of less density than the latter, the side faces of both sections lying in respectively coincident planes.
2. A sealing disk comprising a core section of one material and a ring section of another material, said sections having beveled contemporary engaging faces, the side faces of both sections lying in respectively coincident planes. I 3. A composite sealing disk having a core section of fibrous material impervious to n'ioisture, and an outer ring section fitted to the annular edge of the core section of cork material, the side faces of both sections lying in respectively coincident planes.
In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee, and State of Wisconsin, in the presence of two witnesses.
