CLOSING MEANS FOR JARS AND OTHER. VESSELS,

over the top of the lid and having down wardly-extending arms capable of engaging beneath a horizontal surface or horizontal surfaces provided on the jar. the joint between the lid and jar being made by means of a suitable packing ring interposed between the two.

The invention may be said to consist essentially in constructing the lid and flexible member so that the latter is capable of be- 'ing depressed at its central part relatively to the lid in such a manner as to cause one or both of the downwardly-extending arms to swing outward clear of the above-named surface or surfaces to enable the lid to be readily detached from and applied to the ar.

For convenience the term jar is hereinafter used for denoting any vessel adapted to be closed by a lid, cover, or stopper, whatever may be the shape or construction of the vessel.

The invention will be best understood by reference to the accompanying drawings in which Figure 1 is a central vertical section of a jar and lid, with the improved fastening device, this view showing the lid locked down to the jar; Fig. 2 is a plan of the lid detached from the jar and with the fastening clip removed therefrom; Fig. 3 is a perspective view of the clip detached, and Fig.

4 is a side elevation of a modified form of the clip.

The jar 1 and the lid 2 may be made of pottery ware. The former is provided with a flange 3 by forming it with an-annular recess 4. The joint between the lid 2 and jar 1 is conveniently made by a rubber or equivalent packing ring or washer 5 encircling the central disk-shaped projection of the lid, which enters the mouth of the jar.

Specification of Letters Patent.

Patented Nov. 14 1916.

Application filed April 11, 1912. Serial No. 690,061.

Anannular groove 13. is formed in the underside of the flange 3, and the upturned tip or toe of the projection 12 is inserted into the groove 13, while-the projection 11 simply engages beneath the surface of the flange 3 at a point diametrically opposite the projection 12. The annular recess 4 with its annular groove 13 may, however, be non-existent, except at those two diametrically opposite parts where its presence is necessary for engaging the projections 11 and 12 of the springs: 2'. e., it may be represented merely by two opposite recesses, each provided with a small groove or dent in the horizontal surface bounding the said recess on its upper side.

To, remove the lid or cover 2, the central portion of the blade spring 8 is depressed into the central recess 6, and. the flexing of the said spring causes the arm 9 which carries the projection 11 to swing outward approximately about the point at which such arm joins the spring 8, and as soon as the projection 11 is clear of the horizontal surface of the recess 4:, the lid or cover can be readily turned upward, the projection 12 acting as a hinge or pivot by reason of the engagement of its upturned tip with the groove 13 as aforesaid and as will be apparent from Fig. 1. The application and fastening of the lid or cover 2 take place by a reverse operation, the toe of the projection 12 being engaged with its groove 13, while the said lid is in an inclined position, and the lid being then turned down to the closed position in which the projection 11, after springing over the peripheral edge of the top of the jar, engages the horizontal surface of the diametrically opposite part of the annular recess 4: as will now be well understood.

The blade spring clip 8 may be made in two parts hinged together at 14 as shown in Fig. 4; the manner of fixing the lid 2 (provided with this two-part clip) to, and rethe same as that herein before described and therefore calls for no special explanation.

If desired the upturned part of the tip or toe 12 and the groove 13 may be dispensed with, both of the arms 9 and 10 of this arrangement being provided with similar inwardly-turned projections such as 11.

I claim 7 In combination with an open ended container formed with annular recess so as to leave a flange near its mouth, the flange being provided with recesses in its under surface, packing disposed on the upper end of the container, a cover disposed on the packing and provided with a central depression and a diametrical slot, and a resilient securing member disposed in the slot and provided with depending ends, one of which ends is formed with an inwardly projecting lateral extension to engage under the flange of the container and the other of which ends is provided with a lateral extension terminating in an upwardly projecting toe arranged to engage in the adjacent recess in the flange of the container.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

JOHN SCOTT TAYLOR.
