Application mea my s, 1919. serial No. 295,974.

To all whom z't may concern:

Be it known that I, N ATHANIEL B. WALES, a citizen of the United States, residing at ew York. in the county of New York and State of New York, have invented certain new and useful Improvements in Closures for Containers, of which the following is a specification.

This invention relates to closure caps for bottles, jars, tubes or similar containers and its mainvobject is toprovide an effective sealing device which may be readily applied or removed by mere pressure of the fingers.

The closure is made of metal celluloid or other suitable material which possesses sufficient resiliency to permit of a certain amount of distortion so that it may be sprung out of normal shape to loosen the securing tongues, lips or lugs from the rim or flan e of the vessel or container and will immedlately resumeV its shape when pressure is removed.

I have illustrated the different forms of my invention in the accompanying drawings, in which Figure 1 is a side elevation of a jar or bottle having my closure ap lied thereto; 1Fig. 2 is a slde elevation o the same turned at an angle of 90; Figs. 3 and 4 are vertical sectional views on the line A-A of Fig. 2 showing the closure in locked and unlocked positlons respectively; Figs. 5 and 6 are horizontal sectional views of the closure' in normal and distorted positions respectively; Figs. 7 and 8 are corresponding views of a. modified form of closure; Fig. 9 is a vertical sectional view of a jar or container showing a closure of the type illustrated in Figs. 7 and 8 in unlocked or distorted positlon; Fig. 10 is a fragmentary side elevation of a jar provided with a screw top and showing my closure applied thereto; and Fig. 11 is a plan view of the blank from which the closure is formed.

'My closure member or sealing cap is adapted for use upon bottles, jars, or tubular containers of any of the ordinary constructions in which the neck portion or to is provided with an annular fiange or ri or with an indentation, socket or recess to provide a ledge to receive the securing tongues or lips or gripping fingers of the closure ca I have slixown a jar 1, having an annular recess or groove providing a ledge 2 which may be gripped by the tongues 5 of the closure caps 6.

The closure members are formed of metal or other suitable resilient material and are' -,blank is then stamped into the form shown in Figs. 1 and 2, in which the downwardly turned fiange is provided with a reinforcing expanded annular bead or rib 8 below the slots 7 and from which the tongues 5 depen'd and deflect inwardly.

The' function of the slots 7 upon opposite sides of the flange is to sever the rib portion 8 therebelow from the disk top part so that it may freely yield to lateral pressure. In the form illustrated in Figs'. 1 to 6, the flange portion of the closure member is normally circular in outline as indicated in Fig. 5. By pressing with the fingers against the sides of the ribs or beads 8 midway between the tongues 5, said sides will move inwardly from the position indicated in broken lines in Fig. 6 to that shown in full lines, the annular rib 8 becoming ovate in section. To accommodate `this movement the uncut end portion must bulge outwardly and as the part adjacent the flat disk cannot yield, the tongues 5 must rotate or swing outwardly, the lower free edges making the greatest movement. v

When the sides are pressed inwardly as indicated in Fig. 6, the tongues 5 are separated sufiiciently to permit the cap to be sli ped over the top of the jar or bottle as in icated in Fig. 4, and upon releasing the pressure the fiange will s normal shape indicated 1n Fig. 5. In this position, thetongues 5 take under the ledges 2 of the jar top and lock the cap thereon. The parts may be so designed that the edges of the lips or tongues will strike the up er inwardly inclined sides of ledges 2 so t at the resiliency of the metal will exert a. downward tendency and hold the ca tight upon the rim or mouth of the jar. For the purpose of insuring a more perfect seal, a gasket or packing washer 9 may be interposed between the jar top and the inner side of the cap. This washer may be constructed of cork or other suitable impervious material and thus constitute an inner resilient sealing lining of the cap. This gasket or sealring back into the i ing disk may also serve to seal the slits 7 in the flange of the cap.

For certain purposes it may be desired to provide a greater range of movement of the clamping tongues and of the actuating elements of the flange 8. This may be accomplished by upsetting the metal slightly at .indicated in Fig. 8 in which the b-roken lines indicate the normal position of the parts and the full lines the distorted or unlocked positions. This construction necessarily increases the spring action of the clamp. The greater distance which the tongues will be moved is also indicated in Fig. 9, in which the tongues are in unlocked position.

ln Fig'. 10, I have shown the clamping tongues 5 obliquely arranged at such an angle that they will t over or mesh with and conform to the threads of a jar havingl a screw top or neck. Other .changes and modifications within the spirit of my inven- Vtion will readily appear to engineers and those who understand the principles of my closure cap as above described. v

I claim 1. A closure cap for receptacles, comprising a disk having a depending flange provided with 'oppositely arranged clamping tongues, and the portions between the tongues beingl provided with circumferentially extending slits.

Q. A closure cap for receptacles. comprising a fiat disk having a depending flange provided with a plurality of clamping tongues diametrically arranged, the intermediate portion of the flange being spaced from the receptacleland yieldable, whereby the tongues will move outwardly in opposite directions when said intermediate Harige portions are pressed inwardly.

3. A closure cap for receptacles, comprising a disk having a depending flange provided with oppositely arranged clamping rtongues, and the portions between the tongues being provided with circumferentially extending slits, the part below the slits having an annular bead or rib formed therein.

In testimony whereof I affix my signature.

NATHANIEL B. WALES.
