FOOD CONTAINER AND CLOSURE THEREFOR Filed July 17,, 1929' Patented Dec. 15, 1931 UNITED STATES CHARLES s. BARON, or TIFEIN, 01110 FOOD CONTAINER AND CLOSURE THEREFOR Application filed. July 17,

My present invention relates particularly to glass jars or other containers that are adapted to hold either dry or liquid sub stances.

It has for its chief object, among other things, the. production of such a device having effectual but simple means for closing the same, and preferably means for hermetically sealing it.

1 What constitutes my ,invention will be hereinafter described in detail and succinctly defined in the appended claims,

In the accompanying drawings, which illustrate my invention in a present preferred form of embodiment,

Figure I is a side elevation of a portion of a container made of glass, with its lid or closure attached, and inopen position.

Figure II is a diametrical vertical section of the same but with lid closed.

.Figure'III is a top plan view of the subject and dimensions.

The body 1 is provided witha neck 2, which surrounds and defines its mouth, and whose outer periphery consists preferably of a vertically narrow annular-zone 3that is slightly conical or tapered upwardly about its vertical 3X15. The zone 3 is preferably provided with a peripheral depression or roove 4 to accommodate within it a snugly fitting elastic ring gasket. The groove 4 is flat in cross-section, and the gasket, indicated by the numeral 5, is or becomes by use-slightly conical so, at least, as to fit smoothly intoit and so as to present an outer surface that is substantiallyflush with the outer face of the zone. This is the present preferred form of groove and gasket,qbut a narrow groove 7 1929. Serial-N0. 378,984.

having its bottom curved in cross-section to accommodate a gasket consisting of an elastic grommet 8 whose outer faceprojects a little beyond the face of the zone3, as shown in Figure IV, may be substituted therefor'if desired. Either ofthe gaskets or 8 is made, preferably, of yielding india rubber, but may be made of any like material that may be found suitable for the purpose.

The closure for the container consists, preferably, of a metal lid '9, which is provided with a rim '10 that is conformable to the shape and dimensions of the zone 3. The rim 10 maybe slightly conical in crosssection, conformably to the conical shape of thevzone 3, as'shown in Figure VII, but its angle of inclination may be a little greater than that of the said zone, and its diameter a little less than the longest outside diameter'of'the zone. The outside diameter of *the zone 3 and the inside diameter of the rim 10 are such, relatively to each other, that the smooth edge 12 at the bottom of the rim begins to make contact with the face of the gasket 5 at about or a little above the medial circumferential line of the latter when the lid 9 is applied with pressure to the neck 2. In consequence of the relative diameters, as above described, of the rim 10 and the necksupported gasket 5, continued application of pressure 'tending to force the edge 12 ofthe rim 10 down upon the said gasket, will compress the gasket, with sealing effect between the engaging surfaces of the said members. Also the relationship of the diameters aforesaid, will prevent the edge 12 from passing overthe face of the zone 3 beyond the width of the gasket 5, and will, therefore, maintain at all times an effective yield ing contact between the edge 12 and the gasket.

In respect to the grommet 8, if it be substituted for the gasket 5, the cooperation between it and the rim 1O is-substantially the same as that just described, except thatthe inner face of the rim slips over the contacting face of the grommet with compressing and sealing effect thereupon.

If,'instead of having different. angles of i inclination, as aforesaid, the angles of the zone 3 and of the interior of the rim 10 are substantially conformable, as it has been specified they may be, the gasket 5 must project slightly beyond the surface of the zone 3 in order to make yielding contact with the inner face of the rim 10. In such case, there may be employed for holding the rim 10 and gasket 5 in sealing contact, any sort of suitable latch mechanism, the use of which may be ordinarily dispensed with when the angles of inclination of the zone 3 and rim 10 are different.

In Figures V and VI, respectively, examples of modified outer faces of the neck 2 are shown; and in Figure VII a modified angle of the rim 10. V

The lid 9 may be wholly separable and detachable from the container, but I prefer to operatively unite the container and lid by a suitable hinge connection. With that end in view, I provide, preferably at or near the base of the neck 2, a groove 15- that is substantially parallel to the groove 4, or especially the groove 7, whichit closely resembles. A ring clip 16, being made preferably of a section of spring wire, and selected of a length and gauge to snugly fit within the groove 15, affords a convenient and service able fixed member for the proper assembling together of the lid and the container in hinged relationship. I

In that regard, it should be observed that the mode of application of the lid 9 upon the neck 2 in utilizing the former as a practicable closure to thecontainer is substantially the same in any case, irrespective of whether the lid be separate from or fastened to the container.

The said mode of application in either instance requires, to a considerable degree,

freedom of movement of the lid in order to permit its proper adjustment with proper sealing eff ct upon the neck. Consequently,

it is of importance, in respect to the production of a saleable article, to provide means of hingedly uniting a container and its lid with such looseness in the hinge connection between the parts, as will afford the aforesaid requisite freedom of adjustment of the lid to the neck of the container, and will combine therewith such mechanical fitness, through the proper adaptation ofpart to part and function to function, as will prove attractive to the trade.

The foregoing observation is deemed to be not so obvious as to be out of place herein, because it may obtain due recognition that the problem in the present instance is materially different from that of merely effecting a loose hinge connection, as might, perhaps, without explanation, appear to be the case.

In view of the last preceding observation, it is now further specified that, by preference, the ring clip 16 is provided, substantially at a point diametrically opposite its adjacent ends 17 and 18 with a pintle-ofiset 20 that is disposed substantially well beyond the periphery of the neck 2 and which affords a suitably positioned support for a single elongated knuckle 21 on one side of a hinge plate 22.

For the special purpose of affording a favorable means of connection between it and the other side of the hinge plate 22, the rim 10 of the lid is provided with an everted out side annular flange, 23, consisting of an extension of the metal of the lid beyond the smooth edge 12 thereof, said edge being preferably formed by the bending of the metal of the lid to constitute the flange 23.

The flange 23 not only imparts to the lid a hat-shaped appearance that gives a pleasing finish to the lid, the outer edge of it being preferably edged by a downwardly bent bead, but it is wide enough to extend over the ring clip 16 far enough to afford for it, in effect, a protecting covering. Moreover, the flange 23 affords, in efiect, a suflicient handle for manipulating the lid in the operation'of opening it, no other pose bein necessary.

The outer, edge of the flange 23 and that of the pintle of the offset 20 are substantially in the same vertical plane, and the width of the said flange is sufficient to accommodate two co'alined slits 25 and 26 whose common axis is substantially parallel with that of the said pintle. The slits 25 and 26 are adapted to accommodate, respectively, two metal strips projecting from the side of the plate 22 opposite to the knuckle 21.

Sa1d strips being passed, respectively,

through said slits are thereafter bent, with permanent fleXure, to form knuckles 27 and 28 around coaxial single pintle members 29 and 30 which the slits 25 and 26 define in the flange 23.

The shackle effect of the plate 22 and its knuckles, in combination with their respective pintle members 29 and 30 and the pintle of the offset 20, constitutes a hinge connection which answers all requirements demanded of it in use upon my containen That is to say, it permits all the freedom of adjustment that is necessary for the cooperative accommodation of the rim 10 of the lid 9 to the neck 2. Moreover, it is designed and adapted to effect a substantially even moveitself utility in connect-ion with containers which do not require the sealing effect which is afforded by a yielding gasket and engaging rim 10.

What I claim is:

1. The combination with a container body, and a neck surrounding the mouth thereof, of a ring embedded in an annular depression provided for it in the outside of the neck, a pintle-offset formed in the ring, a lid, and a hinge member pivoted to the lid and to said ofi'set, respectively.

2. The combination with a container body, and a neck surrounding the mouth thereof, of a ring embedded in an annular depression provided for it in the outside of the neck, a pintle-oifset formed in the ring, a flange defined hat-shaped' lid, and a hinge member pivoted to the flange of the lid and to the oflset, respectively.

In testimony whereof, I have hereuntoset my hand.

CHARLES S. BARON.
