Description

F. FIESE JAR CLOSURE Feb. 18, 1936.
Filed Nov. 24, 1935 Y W m 4 a m T Attorney V Patented Feb. 18, 1936 UNITED STATES PATENT OFFICE JAB CLOSURE Frank Fiese, North Platte, Nebr. Application November 24, 1933, Serial No. 699.608 1 Claim. (Cl. 21545) This invention relates to receptacle closures and has as its object the provision of an improved cap for Mason" jars and the like.
In accordance with the present invention a cap of the character indicated can be used for sealing the jar and in conjunction with, or auxiliary to, the usual screw cap.
In the drawing: Figure 1 is a vertical section showing the improved cap.
Figure 2 is a top plan view. Figure 3 is a plan view of one form of sealing ring, and
Figure 4 is a sectional view through the ring. 16 Referring to the drawing by numerals, 5 indicates a glass jar having an externally threaded neck 6.
My improved cap I is formed of rubber or other suitable, elastic material; and is cupshaped. The cap is adapted to fit down into the neck 6 as shown, and at the top thereof, the rim or wall of the cap is provided with an outturned flange 8 that rests on the edge of the neck 6 of the jar. Thus, when in place, the usual screw cap (not shown) may be screwed into the jar neck 6 without interference from the cap I. A split resilient sealing ring 9 of wire or the like is provided, and is adapted to fit within the 30 cap 1 to force the wall or rim of the cap up tight against the inside of the jar neck 6. In accordance with the invention the neck 6 is provided with an internal groove l0, and when ring 9 expands it will force a portion of the wall of the cap into this groove It], in a manner shown in Figure 1 and thereby effectively seal the jar.
To facilitate contraction of the ring, for the positioning and removal thereof with reference 6 to cap I the ends of the ring are bent backwardly as at 9a and inwardly of the ring as at 9b to provide projections II which inclines above the plane of the ring proper, as shown in Figure 4, so that they may be easily grasped by the hand 10 or suitable tool, as for e. g. pliers, to draw the ends of the ring inwardly toward one another to contract the ring.
As shown in Figure 2 the ring may be provided with an inwardly extending U bend I2 to permit a portion of the rim of the cap 1 to work inwardly away from the wall of the jar neck 6 in a manner to efiect an escape of the steam where it is desired to cold pack or can the fruit or the like. For "straight canning a ring such as shown in Figure 3 would be used.
What is claimed is:
In a jar closure, a flexible jar insertable cap,
a slit expansible retaining ring for engagement into the cap to expand the cap against the inside of the jar, the ends of the ring being bent backwardly in opposite direction, and a projection on the ends of the said backwardly bent portions, the said projection extending inwardly of the ring proper, said backwardly bent portions adapted for overlapping relation when the ring is engaged with a cap.
