A packing-washer E of ordinary construction is used in connection with the cap, as illustrated in the drawings.

From the foregoing description the use and operation of our improved device will be readily understood. After the receptacle has been filled the cap is placed in position and the bail made to engage the recesses on the opposite sides of the receptacle in the usual manner. The bail is then raised until its transverse part engages the curved projection or cam (1 of the cap (I. This transverse part of the bail is then moved upwardly until it engages the recess C. It will be understood that since the part C of the cap curves u 'iwardly from the base or lower portion of the cap the transverse part of the bail will be bowed upwardly as itapproaches the central position or the reccss (l of the sap. It will also be understood that the degree of the curve of the part G of the cap may be regulated as desired, whereby the necessary pressure may be given to the cap through the instrumentality of the bail when the latter is in the locking position.

' Havingthus described our invention, what we claim is- 1. The combination with a bottle, jar or similar receptacle, of a bail whose extremities are pivotally connected to the opposite sides of the receptacle, and a closure applied to the top of the receptacle and having a cam-shaped projection formed on top thereof and adapted to spring the transverse part of the bail upwardly, as the latter is movedto a central position transversely of the said projection, the cover being provided with recesses located on opposite sides of the cam-shaped projection for the purpose set forth.

2. The combination with a receptacle of the class described, of a cap or closure applied to the top of said receptacle and having an upwardly-projecting cam-shaped part which is highest at the top, the said cam-shaped part having smooth edges and a shallow central recess at the top, and recesses on opposite sides of the can1shaped part, and a bail centrally pivoted in the opposite sides of the body of the vessel and having a transverse part adapted to engage the earn-shaped part of the cap, whereby as the bail is moved upwardly to the center of the cam-shaped part, the said bail is placed under tension and engages the central recess at the top of the cap, substantially as described.

In testimony whereof we aflix our signatures in presence of two witnesses.
