It is to be understood that in addition to milk bottles the invention may be applied to other bottles or like containers for which a deformable cap such as one of aluminium foil is to be provided.

I claim:

1. In-combination a bottle or like container comprising an external rib around the container in the neighborhood of the mouth thereof and formed with a downwardly directed shoulder, said rib being provided with a plurality of swaging projections extending downwardly therefrom and having edges forming parts of said shoulder, and a deformable cap completely covering said swaging projections and having its skirt portion swaged under said downwardly directed shoulder at-all points around the complete periphery of the mouth of the bottle.

2. The combination as claimed in claim 1 in which the projections are substantially triangular with an apex of each projection directed downwardly.

3. In combination a bottle or like container comprising an-annular groove around the exterior of the container in the neighborhood of the mouth thereof, said groove having along its upper edge a downwardly directed shoulder, a. plurality of swaging projections extending into said groove and spaced around the container, said projections having edges forming parts of said shoulder, and a deformable cap covering said projections and having its skirt portion swagedunder said downwardly directed shoulder at all points around the complete periphery of the 5. In combinations bottle or like container comprising a mouth having a lip bounded bya grooye, thus forming a downwardly directed shoulder, a plurality of swaging projections extending from said shoulder and spaced'arou'nd the container, said} projections having edges forming parts of said shoulder, and a deformable cap completely covering said swaging projections and having its skirt portion swaged under said downwardly directed shoulder atall points around the complete periphery of the mouth of the bottle.
