Nev. 8, 1938.
Filed March 25, 1936 ATTORNEY Patented Nov. 8, 1938 UNITED STATES PATENT OFFICE.
7 Claims.
This invention relates to closures for jars and the like, and more particularly to a closure of this character having a separable lid provided with means for facilitating removal of the closure from a jar.
It is well known that an extremely tight seal is required of containers, such as jars of the Mason and other types suitable for containing foodstuffs, in order that dust, moisture, air and other foreign elements may be effectively excluded from the interior of the jars, to thereby prevent spoilage or deterioration of the contents of the jars.
It is also well known that while a tight seal for a jar of the character stated is indispensable, difnculty is often encountered, because of the tight seal required, in removing the closure to make the contents of the jars available for use.
It is, therefore, the principal object of the present invention to provide a closure for jars and the like by use of which the desirable and customary extremely tight seal for the jars may be employed, and yet little or no difficulty encountered in opening the jars for utilization of their contents.
In accomplishing this and other objects of the invention, I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawing, wherein:
Fig. l is a perspective view of my improved closure showing the manner of its application to the neck of a jar. I
Fig. 2 is a detail disassembled perspective view of a jar closure embodying the features of my invention, parts of the sealing and clamping rings being broken away to better illustrate their construction.
Fig. 3 is a view similar to Fig. 1, showing the upper sealing ring in the process of being removed to loosen the clamping ring in relation to the neck of the jar.
Fig. 4 is a vertical cross-section on the line 4 -4 Fig. 1, particularly illustrating application of an assembled closure embodying the features of my invention to the neck of a jar, and showing the finger depressions of the lid extending beneath the upper sealing ring for facilitating grasping same.
Fig. 5 is a vertical cross-section on the line 5--5, Fig. 1.
Fig. 6 is a vertical cross-sectional view through the central portion of a modified form of closure, wherein the flange of the clamping ring substantially covers the upper sealing ring, and showing the application of a tool to a perforation in the ring for effecting removal of the ring.
Referring more in detail to the drawing:
I designates a conventional jar, preferably of the Mason type, having the usual threaded neck 2. This type of receptacle is. widely used,
particularly for canning and preserving foodstuffs, one of the chief problems of which art is to seal a filled receptacle or jar in such a manner that it remains air-tight until disposal of the contents of the jar is desired.
To effect such a seal, I provide the lid or cover member 3 formed of suitable material, preferably glass, and. having a diameter substantially equal to the outer diameter of the edge 4 at the open top' of the neck portion of the jar l. The bottom face of the lid 3 is provided with an annular rib 5, as shown in Fig. 4, spaced inwardly from the periphery thereof and forming a retaining wall for a compressible gasket member, for example a rubber ring 6, the ring 6 being sleeved over the outer periphery of the rib and resting on the edge l of the neck of the jar to seal the jar when the lid is placed thereon, in such a manner that the outer peripheries of the neck 2, ring 8 and lid 3 are in substantially vertical alignment. It is apparent that while I have shown the rib 5 as spaced from the inner periphery of the neck 2, it may be formed as a. mating portion with the neck for facilitating positioning the lid on the neck of the jar.
The central body portion l of the lid, which is bounded by the rib 5, may also be provided with a slightly concaved surface for increasing the strength thereof, as shown in Figs. l and 5.
The upper face of the lid 3 has a raised portion 8, the periphery of which forms a positioning and retaining wall for a sealing ring 8, preferably similar in construction to the ring 6, which is sleeved over the portion 8 in such a manner that the peripheries of both faces of the lid 3 are provided with compressible gaskets aligning with the outside periphery of the neck of the jar.
Ill designates an open top clamping ring having the usual threads for mating and engaging with the threaded neck 2 of the jar. The clamping ring lit is also provided with an inwardly extending peripheral flange l engageable over a portion of the upper gasket'ring 9 for causing compression thereof, when the clamping ring is screwed down on the neck of the jar, the ring 9 in turn compressing the lid 3 and ring 6 upon the upper edge 4 of the jar in order to secure the lid in sealing position.
To break the seal for removal of the closure in order to make the contents of the jar available for use, I provide the upper face of the lid' 3 with finger depressions l2, which are preferably diametrically spaced, and which extend from a point within the periphery of the raised portion 8 out- Wardly and downwardly toward the periphery of iofu the lid 3 to underlie a portion of the ring 9 and flange I l, in such a manner that the inner edge pression incident to removal easily and quickly pulled from sealing position between the flange H and lid 3, as shown in Fig. 3.
It is apparent that with the ring 9 removed from the closure, the compression upon the clamping ring Ill and the neck 2 of the jar, caused by screw pressure of the clamping ring, is sufficiently reduced to allow easy by unscrewing the clamping ring for permitting ready access to the contents of the jar.
In Fig. 6 I have illustrated a modified form of clamping ring l3 and upper sealing ring M for use in instances wherein it is desired to substantially cover the ring 14 with a flange 15 on the clamping ring l3 of greater width than the flange 1:! of clamping ring Hi. In this case, the assembly f the closure and the construction of the lid 3 is similar to that shown in the preferred form of invention; however, the upper sealing ring [4 is provided with perforations l6 spaced .around the body of the ring in such a manner that certain of the perforations are juxtaposed over the finger depressions 12 below the flange l5. With this construction, it is desirable to compress the lower ring 6 preferably by manual pressure on the upper face of the lid 3 to reduce the compression upon the upper ring M, a suitable tool I! then being engageable in one of the perforations of the ring when inserted in one of the depressions l2 for effecting withdrawal thereof by drawing the ring from beneath the flange to thereby facilitate the subsequent unscrewing of the clamping ring due to the reduced comof the ring l4.
While I have illustrated my invention as applied to jars of threaded neck type, it is apparent that closures embodying the features of my invention may be employed with other types of receptacles.
What I claim and Patent is:
1. A closure of the character described including a cover member having a rib on the lower face thereof and araised portion on the upper face thereof for positioning sealing rings equidistantly from the center thereof at opposite sides of the cover member, sealing rings mounted on opposite faces of said cover member by said rib and raised portion, and a clamping member having a flange overlying the upper ring, the cover member having finger grooves in its raised portion extending beneath upper ring for facilitating removal of said ring from under the flange to release compression on the lower ring. 7
