JAR CLOSURE Filed July 20, 1953 Patented Apr. 2, 1935 urrEo sr JAR CLOSURE 1 Robert D. Elliott, Huntington Park, Calif.
Application July 20, 1933, Serial No. 681,384
1 Claim.
closure, means being provided for normally exerting pressure on the closure thereby forcing the closure into close engagement with the sealing ring of the device.
An important object of the invention is the provision of a jar having means whereby the closure or lid may be positioned in such a way that steam or pressure may escape, while the contents of the container are boiling, during oven canning.
Another object of the invention is the provision of a spring steel securing member, means being provided for centering the securing member with respect to the top of the lid, insuring a close fit between the cover or lid, and the container.
A still further object of the invention is to provide a jar lid having a continuous flange against which the sealing rubber rests, the flange acting to brace the sealing rubber and eliminate any possibility of the sealing rubber being forced outwardly by pressure within the jar.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawing:
Figure 1 is a plan view of a jar constructed in accordance with the invention.
Figure 2 is a side elevational view of the jar and its lid.
Figure 3 is a vertical sectional view through the ar.
Figure 4 is a plan view of the spring steel securing member.
Figure 5 is a side elevational view thereof.
Referring to the drawing in detail, the jar or body portion is indicated generally by the reference character 5, and as shown the upper outer surface thereof is cut away defining a shoulder 6 and an annular upstanding flange l, the upper edge of the flange providing a seat for the rubber sealing ring 8, against which the closure indicated at 9, engages in providing an airtight seal between the jar and its lid or closure.
Formed integral with the body portion 5 and extending laterally therefrom, are pairs of upper and lower lugs 8' and 9 respectively, the lugs of each pair being disposed on opposite-sides of the body portion, as clearly shown by the drawing.
The upper surfaces of the lugs are inclined downwardly, for purposes to be hereinafter more specifically described. The closure or lid is bulged outwardly, and is provided with a lug IE] rising from the central portion thereof, the lug providing a centering pin for the spring steel securing member H, which has a central opening I2 for the reception of the lug Iii, whereby the securing member is held centered on the closure, to the end that the securing member may be readily and accurately positioned, before pressure is exerted at the ends thereof, to bend the securing member downwardly.
In the construction of the closure, the center of the bulged portion thereof lies in a plane an appreciable distance above the lugs 8 and 9', so that when the securing member H is positioned, and the ends thereof are sprungdownwardly engaging the lugs 8, the securing member will be placed under slight tension, so that movement of the closure with respect to the body portion, will be permitted, to the end that pressure within the jar may be relieved, when the jar is used in oven canning.
It will, of course, be understood that when the material has been properly cooked in the jar and the jar removed from the oven, the ends of the securing member H may be pressed downwardly and rotated slightly, until the ends of the securing member engage lugs 9, thereby providing an air tight seal between the jar and closure.
In order that the securing member will securely grip the lugs 8' and 9', the ends of the securing member are bent laterally as at I3, the extremities thereof being bent inwardly as at M to hook under the lugs, holding the securing member in its active position. v
Bosses [5 are formed on the upper surface of the securing member I I, the bosses being disposed near the ends thereof, so that they provide means whereby the securing member may be conveniently gripped for the operation of the securing member in removing or positioning the same.
A notch I6 is formed in one edge of the closure, and affords means whereby a suitable instrument may be positioned for prying the lid or closure from the jar.
In view of the foregoing, it will be obvious that due to the construction shown and described, a container is provided which may be conveniently used for oven canning, and may be also operated to accurately seal the contents of the jar or container, after the cooking operation has been completed.
Having thus described the invention what is claimed is: I
In a combined cooking and preserving jar, a body portion, lugs extending from opposite sides of the body portion and near the upper edge of the body portion, lugs extending from opposite sides of the body portion and disposed in planes below the first mentioned lugs, the last mentioned lugs being spaced laterally from the first mentioned lugs, the lower surfaces of all of the lugs being parallel to the upper end of the body portion presenting shoulders, the upper surfaces of the. lugs being inclined downwardly, a cover for the body portion, a yieldable securing member positioned over the cover, hooks at the ends of the securing member and adapted to engage under the first mentioned lugs holding the cover in position whereby the cover may be elevated by steam pressure within the body portion during the cooking process, said hooks adapted to be positioned under the second mentioned lugs holding the cover in sealed position, said hooks adapted to move over the inclined upper surfaces of the lugs when positioning the securing member, and the main portion of the securing member engaging the cover throughout substantially the entire length of the securing member.
