Specification of Letters Patent.
Patented July 20; 1909.
Application filed December 21, 1908. Serial No. 468,663.
To all whom it mag concern:
Be it known that 1, ROBERT V. LYON, of
State of New York, have invented certain new and useful Im rovements in Bottle- Sealing Devices; and do hereby declare the follow ng to be a-full, clear, and exact description of the same, reference being had .to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.
The resent invention relates to bottle sealing devices of the type in which a cap is employed and is secured to the exterior of the bottle for holding "a sealing. material infirm contact with the walls-of the mouth of the bottle; and an object of this invention is to ing tool of the kind cooperating with the cap retaining me s and the upper surface of the cap, may be e ctively engaged with the latter to prevent accidental slipping of the tool and injury to the hands oft e operator.
Tothis and other ends the invention consists in certain improvements and combina tions of parts all as will be hereinafter. more fully described, the novel features being pointed out inthe claims at the end of the specification.
In the drawings: Figure 1 is a verticalsec tion of the upper ortion of a bottle with the improved sealing evice thereon, a tool being shown in section to illustrate the operation of the invention; andFig'. 2 is a perspective view of the sealin device and the removing tool cooperating t erewith.
Referring more particularly to the drawings, 1 indicates a portion of a bottle which has an exterior annular shoulder 2 about its up er end. A, sealing device or disk 3 prefera ly in the form of yielding material such as cork rests upon the upper ed e at the mouth of the bottle andis preferab y carried within "and covered by a cap that may be made from sheet material such as sheet metal.
has projecting downwardly from eriphery a retaining device which pref- Ely consists of an annular flange corruits era
gated at its edge, the depressed portions 4 of ,the corrugations being engaged with the shoulder 2 on the bottle and the elevated portions 5 being adapted for engagement by a removing tool. 1
The removing tool which is most enerally employed for detachin caps of t is ty from the bottles is in t e form of two su stantially straight portionsfi and 7 connected at their ends by arms '8 to form a loop. In-removing the cap the portion 6 is'engaged beneath the elevated portions of the retaining flange, and the portion 7 is engaged with the top of the cap near or at its center in order to provide a wide bearing surface, and to prevent the tilting of the tool, the top being substantially flat and smooth or continuous in order that the tool may be engaged therewith at any'point on its periphery.
While the smooth upper surface of the cap hasthe advantage mentioned, it also has the disadvanta e that the tool is liable to and often does s ip and in many instances cause a hand of an operator of the tool to engage the retaining flange in a manner to injure the hand. To overcome this slipping of the tool there is provided in this invention an tion extends over and supports the greater portion of the sealing material that is .ex-'
posed to internal pressure within the bottle.
This arrangement not orfly permits the sealing material to be supported efliciently by the flat portion when the projection is struck u and made hollow as shown, but the bar 7 oi the cap removing device may be caused to engage the cap substantially at the center. To secure a projection of suflicient height without destroying or breaking the 1 metal of the cap during the stamping or pressing operation it is desirable that the smooth annular portion about the projection be very slightly inclined'fromthe pe-' riphery of the capto the base of the projection as shown in Fig. 1. Internal pressure will force the sealing material against the flat portion before the sealing material will be ruptured.
In removing the cap the tool is placed on the periphery so that thebar 6 engages beneath the retaining flange and the ar 7 engages on the opposite side of-the projection 9 Upon upward pressure on the handle of they tool the bar 7 rldes downwardly on the projection to engage the top 10 and to draw the bar "6 farther beneath the retaining flange, thus efiectively locking the tool to the cap. A further upward movement oi the tool removes the cap. I
A sealing device constructed in accordance with this invention costs no more than devices now on the market and at the same time it positively prevents slipping of the removing tool, thus .insuring the operator portion extending from the base of the proagainst injury and permitting the cap to be removed more quickly.
I claim as my invention: 1. The combination with a bottle having a head provided with an upper edge. of the bottle, of a cap covering the sealing disk and embodying a cone shaped projection with smooth external walls, a substantially flat'wide annular disk jection to'the periphery of the cap and-supporting the greater portion of the sealing disk, and a retaining flange extending downwardly fromthe periphery of the. capinto engagementwith the exterior annular shoulider of the .bottle.
2. The combination with .a sealing element, of a cap for the same provided with a downwardly extending retaining flange, a centrally arranged cone sha ed projection having smooth external walls, and a subexterior annular shoulder, and a sealing disk resting upon the stantially flat disk portion extending from the base of the projection to the periphery.
3. The combination with a'sealing disk, of a cap for covering the same having a retaining flange extendin downwardly therefrom, an anti-slipping e ement arranged centrally of theitop of the cap and having a smooth inclined wall to be enga ed by a removing tool to draw the latter. eneath the retaining flange, the top surface of the cap between said element and the periphery be ing annular and substantially flat to provide a firm bearing surface for the tool.
4. The combination with a sealing disk,
of a cap covering the same and provided walls, a wide substantially extending from the base and a retaining flange extending ownwardly at the periphery and provided with corrugations.
