H. V. WILLIAMS JAR CLOSURE Filed Dec.
flora 0e l/MZ/z'akma ATTORNEYS Patented May 3, 1938 UNITED srres PAENT GFFIQE 1 Claim.
The object of the invention is to provide a jar closure construction whereby jars of glass or similar material may be eliectively sealed air tight; to provide a closure construction embodying a rubber gasket or sealing ring so arranged that the sealing ring will be compressed throughout in the sealing operation and not subjected to a pull or tension, as in conventional practice, which tends to open the pores of the material;
10 and generally to provide a jar. closure which is of simple form and susceptible of cheap manufacture.
With this object in View, the invention consists in a construction and combination of parts 15 of which a preferred embodiment is illustrated in the accompanying drawing, wherein:
Figure 1 is an elevational view of the invention, with certain parts broken away.
Figure 2 is a detail sectional view showing the 20 mouth of the jar and cap attached with the parts in position prior to the application of a pressure on the sealing ring.
Figure 3 is a view similar to Figure 2 but showing the relative position of the parts when the 25 cap is in fully closed position.
It is preferable to have the jar l and the cap clamping ring I l of the same diameter, and thus the mouth of the jar is formed by contracting the latter circumferentially, as indicated at l2, this 30 contraction providing a neck portion [3 of which the upper edge is beveled on the outside, as indicated at 14, and similarly beveled on the inside,
as indicated at l5, the angles of the bevels being uniform on opposite sides of a vertical line pass- 5 ing through the peak 15 of the neck.
The cap I! is formed with a pendent annular flange l8 of an exterior diameter to be readily received within the neck l3 and exterior to the flange has a ledge portion E9 of which the under- 40 face is channeled, as indicated at 29, to provide synclined walls which, when the cap is in position on the jar, parallel the beveled edges I4 and I5 of the neck.
The cap ll is recessed on its upper face adja- 45 cent its periphery to provide a seat for the inturned flange 2| of the clamping ring I I and the latter at the lower edge has inturned lugs 22 engag'eable with the ribs 23 with which the neck is provided onv its periphery. The ribs are formed with inclined under edges and are arranged around the neck in a circular series with the nose end of one materially spaced from the heel end of the next. Thus in applying the ring, the lugs pass between adjacent ribs and on rotation of the ring they slide down the inclined under-faces of the rib and thus draw the cap down on the neck.
The sealing ring it is placed on the cap in sur- 10 rounding relation to the flange l8 before the cap is applied and rests in the channel 20 but on the inclined wall of the latter next to the flange l8. Thus, when the cap is applied, the underface of the sealing ring rests on the beveled wall and 15 when the clamping ring is rotated the material of the sealing ring is compressed, as shown in Figures 1 and 3. The sealing ring is at no time subjected to tension at any point. Rubber is naturally porous and its effectiveness as a seal- 0 ing medium depends on its being subjected wholly to compression. The present invention provides such a use, the inner beveled edge l5 of the neck, the flange I8 and the channel of the cap serv ing to so embrace the sealing ring that the material thereof is compressed solely as the cap is drawn down on the neck when the clamping ring is rotated.
The invention having been described, what is claimed as new and useful is:
A jar and closure therefor, the former having a neck of which the upper edge is beveled interiorly and exteriorly and the latter channeled to provide walls paralleling said beveled edges when the closure is attached, and an elastic sealing ring seated upon the inner beveled edge and of a width corresponding to the width of said edge, the closure having an annular pendent flange on the undersurface of an exterior diameter corresponding to the interior diameter of the neck, and means for attaching the closure to the jar and subjecting the sealing ring to compression in so doing, the flange engaging the sealing ring on the inner periphery with the adjacent inclined wall engaging it on the upper face, the other inclined wall of the closure engaging the ring on the outer periphery as the latter is compressed.
