Description
Dec. 17, 1935. El, W MISSEL 2,024,657
CAP FOR FRUIT JARS Filed Dec. 5, 1955 INVENTOR 527W 2% wael Patented Dec. 17, 1935 UNITED STATES PATENT OFFICE 3 Claims.
The object of this invention is to provide an improved form of cap or top for a glass fruit jar or fruit can, which top can be screwed into place on the can and with a rubber washer easily makes a tight joint between the top and the can, so that the can is easily and fully sealed and is easily opened, the preserved fruit being kept in good condition in the jar.
These and other objects of the invention will be illustrated in the drawing, described in the specification, and pointed out in the claims at the end thereof.
In the drawing:
Figure 1 is a vertical section through the can and the top or cap therefor.
Figure 2 is a top plan view of the cap showing an octagon head on a circular cap.
Figure 3 is the Wrench by which the cap is screwed in place or removed.
In the drawing like reference numerals indicate like parts.
In the drawing reference numeral I indicates the glass fruit jar provided with a neck 2 having a male thread 3 molded thereon.
4 indicates a metal top or cap for the fruit jar, which cap has an octagon head 5 formed centrally thereon, under which is a shallow cupshaped recess 6 in which is provided a porcelain disc 1, which disc can be round or octagon and is cemented or pressed into place. The head is provided with an annular flange 8 which is inclined both upwardly and out, from which extends downwardly a cylindrical base 9 having a female thread it formed therein, which is adapted to engage the male thread on the neck of the fruit jar.
The under side of the 'annular flange 8 is adapted to hold a washer l I, the flange 8 and the washer H both having the shape of a truncated cone inverted.
When the cap is screwed on to the fruit jar the rubber washer is forced against the inner edge of the mouth of the fruit jar into close engagement between the flange of the cap and the edge of the fruit jar, and if there is uneven bearing, the cone-shaped flange will center itself in the mouth of the jar and thus correct any unevenness in the bearing. As the rubber washer bears on the corner or inner edge of the mouth of the bottle, it will 'be more easily forced into intimate contact with the mouth of the bottle and form a perfect seal therewith than if it had a flat bearing thereon. Experience shows that this seal is much more accurate and dependable than if the flange of the cap and washer were merely a flat ring that was forced downward against the mouth of the bottle so as to engage with the whole width or thickness of the rim of 5 the mouth of the bottle.
The washer is of suflicient width so that the free inner edge thereof overlaps and engages with the outer edge of the porcelain disc and effectually covers all of the metallic part of the 10 top, so that the fruit or vegetables in the bottle cannot get into contact with the metal of the cap.
A can with the top formed in this way can be turned upside down and left for days without 15 showing any sign of leakage.
I claim:
1. A cap for a fruit jar having a head formed centrally thereon, having a cup-shaped recess on the under side thereof, a downwardly pro- 20 jecting rim bounding said recess, a porcelain disc in said recess, an annular flange surrounding the lower edge of said rim, which flange is inclined upwardly and out, a cylindrical base extending down from the margin of said flange. 25
2. A cap for a fruit jar having a head formed centrally thereon, having a cup-shaped recess on the under side thereof, a downwardly projecting rim bounding said recess, a porcelain disc in said recess, an annular flange surround- 30 ing the lower edge of said rim, which flange is inclined upwardly and out, a cylindrical base extending down from the margin of said flange, the under side of said flange being adapted to hold a washer in parallel relation thereto, said washer 35 being adapted to engage first the inner edge of the rim of the jar and be centered thereby.
3. A cap for a fruit jar having a head formed centrally thereon, having a cup-shaped recess on the under side thereof, a downwardly projecting 40 rim bounding said recess, a porcelain disc in said recess, an annular flange surrounding the lower edge of said rim, which flange is inclined upwardly and out, a cylindrical base extending down from the margin of said flange, the under 45 side of said flange being adapted to hold a washer in parallel relation thereto, said washer being adapted to engage first the inner edge of the rim of the jar and be centered thereby, said cup-shaped recess on its top side having a male 50 octagon shape projecting above the rim of the cap and adapted to be engaged with the wrench.
