JAR- CLOSURE.
Specification of, Letters Patent.
Patented Nov. 4, 1913..
Application filed July 2, 1913, SerialNo. 776,909.
particularly to that type of closures in.
which the sealingmember or gasket is held to its seat on the jar or bottle and confined against possible leakageby a sealing cap, and my invention primarilyhas for its ob- 'ject to provide an improved jar and closure member therefor in which the several cooperating parts are so constructed and designed to coact in sucha manner whereby the sealing gasket or member can be quickly and securely applied without the aid of a special implement and whereby the same may be conveniently removed from the jar or bottle.
Another and important object of my invention is the provision of a closure means of the general character stated, adapted for constant reuse and in which the sealing member or gasket is at all times contained within the cap and is thereby not separated from the cap when the closure is removed from the jar and in, which, the cap of the closure member is so formed that a worn sealing member can be removed therefrom and a new sealing member may be substituted therefor.
My invention consistsof the eculiar arrangement and construction 0 the parts hereinafter fully explained, s ecifi'call'y pointed out in the appended c aim and illustrated in the accompanying drawing,
in which:
Figure 1 is a perspective view of a jar with my improvements applied. Fig. 2 is a similar view that illustrates the manner in which the cap and the sealing members are removed from the j ar. Fig. 3 is a transverse section of the upper end of the jar, and the closure devices, taken substantially on the line 22 on Fig. 1. Fig. 4 is a similar view that illustrates the first position of the closure devices in fitting them over the jar. Fig. 5, the second position, the clamping fingers being shown as spread to pass over the lower or looking flange on the jar. view of the closure cap and the sealing disk and gasket.
Fig. 6 is a perspective- In carrying out my invention, the jar or bottle 1 has its upper or month end especially constructed for cooperating with my construction of closure device, and to. such end the mouth of the jar has an annular rib, 2 adjacent the opening 3 that rises up from and forms, as it were, a portion of the annular hearing or rim 4 upon which the sealing ring or gasket of the closure, devices seats.v I
The outer edge of'the rim or seat 4 is rounded and merges with an. annular groove 5, the lower portion of which merges with a second annular flange 6 having a substantially undercut edge that ends at \the contracted or neck portion 7 of the jar body, as is clearly shown in Figs. 3, 4 and. 5, by reference to which itwill be also seen that the outer edge of the seat or rim 4 and the flange 6 are of different d-iameters, -the reason for which will presently appear.
The closure device for my improved construction of jar, includes a gasket or sealing ring 8 of any suitable compressible material, a parafiin disk 9 on the under side of the ring anda like disk 10 on the upper side of such ring.
11 designates what I term the cap and locking member of the closure device, since it serves as a cap or, cover for the ar mouth and the means for holding the washers and disks in an air-tight position over the jar mouth. The cap. is formed of a resilient sheet metal and consists of the top or body portion, a'pendent flange 12 that is cut out or scalloped to form a series of pendent members 13, the lower ends of which are bent inwardly on a slightly upward incline to form locldng fingers 13*.
By reason of constructing the closure devices as stated when once slipped within the scalloped flange of the cap, the gasket and the paraflin disks cannot be dropped out of the cap when fitting the closure devices either onto or off the jar, but they may be readily forcibly removed from, the cap by buckling or bending up the gasket and the disks when it is desired to substitute new.
- has gage the rounded outer edge of the upper or seat face of the jar and are thereby caused to spread, until they pass over the said rounded edge, after which the spring of the scallop members causes their lower or finger ends to 'hug the annular depression in the jar below the said edge and thereby hold the cap true as it is further forced down to the second position (see Fig. 5) at which time the sealing members will be in engagement with the top of the jar and locking finger just ready to slip over the outwardly curved undercut flange of the jar to become interlocked therewith to securely hold the closure devices air-tight over the jar mouth.
It should be stated that in forming up the closure devices, particularly the cap, the pendent members with the interlocking or inbent portions and the lower or looking flange on the jar are relatively so proportioned that it will require some pressure to bring the locking fingers of the cap over the locking flange after the closure device (Fig. 5).
To remove the cap it is only necessary to spring out the longer fingers from one side of the jar, after which the cap with the sealing members may be readily swung ofl (see arrow Y) the jar.
Although my construction of closure devices may be cheaply manufactured they may be reused anumber of times and when desired new gaskets substituted for the Worn ones.
By forming the top rim of the jar next the opening with a raised annular rib, a supplemental means is provided for positively eifecting an air-tight" seal, since the paraffin disk and the washer are caused to bite down over the rib when the cap is closed down.
Among other advantages, in the use of gone down to the second positionmy jar and closure therefor, is, that by reason of forming the jar body with an inwardly curved annular groove just above the locking flange thereof, the closure member, after the jar is filled with the contents to be cooked, can be applied and held to the second position, that is with the locking fingers engaging the annular groove in the jar while the contents are being cooked,-
the position of the cap allowing the sealing members to rise 03 their seat during the cooking.
When thus positioned, after the contents have been cooked, all that is then necessary is to slap down on the cap to cause it to assume the final or locked position shown in Fig. 3, it being obvious that when thus applied as the jar and the contents thereof 0001, the vacuum created causes the closure devices to form a perfect sealing of the jar.
What I claim is:
As a new article of manufacture, a jar having a mouth and two distinct annular grooves on its outside adjacent to said mouth to form a shoulder portion at the intersection of such grooves, the under face of said shoulder being straight out, the first of said grooves being curved throughout UMBERTO MAGNI.
