With the above and other objects in View, the invention. further includes the following novel features and details of construction, to

be hereinafter more fully described, illus trated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is an edge view of a cap constructed in accordance with the invention.

disposed channelshaped grooved or depression 14:, while the flange 11 is slitted as shown at 15, the slit extending inwardly from the outer edge of the flange but terminating slightly spaced from the inner edge of the flange. The slit 15 is located in a line with the center of the groove or channel 14: and may be provided at each end of the channel as shown in Figure 2 of the drawings, or at one end of the channel as at 15', in Figures 4 and 5 of the drawings. In these last mentioned figures, the cap is-provided with asubstantially squared edge 16, instead of the rounded edge shown in Figures 1, 2 and 8 of the drawings.

The cap is preferably provided with a cork or other suitable insert 17 and the said cap is crimped in place as previously stated.

-When it is desired to remove the cap, the

convex 0r dome-shaped top 10 is pressed inward as shown in Figure 6 of the drawings so as to separate the flange at the slit or slits 15 or 15', so that the flange will move away from the bead 12, whereupon the cap may be readily removed.

The invention is susceptible of various 7 changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall-within the scope of the appended claim.
