Application March 5, 19,45,- Serial No. 581,086 ' l . This inventionl relates to containers and par ticularly to containers of that type having a body , of glass or similar vitreous material and ametal sealing closure by which the container is closed and sealed,.which closure is so constructed that when the container is opened, the cover element will remain hinged to the container so that it can be repeatedly opened and closed again. One of the objects of my present invention is to provide a container of this general type in which the metal closure member comprises a band i 5 terial` and which is shown as provided with .the neck portion 2, and with an exterior downwardly facing shoulder 3,V The outer surface 4 of the neck 2 >between the top edge and the shoulder 3 is slightlyr'tapering, said surface being slightly [smaller at the top edge than at the shoulder., ~ lThe metal ’sealing'closure for the container f comprises a cap element 6, a band elementi-and a sealingstrip, shown at 8 in Figs. 1 to'4. "The band element 1 encircles the portion of Ythe neck 2 immediately above the shoulder 3, said , element which encircles the upper end of the con Aband tightly fitting such exterior surface., The tainer and is provided at its upper edge with an lower edge 9 of the band element is bent inwardly outwardly extending sealin-gñange and also com under theshoulder `3, and the upper edge `of the prises a cap element formed with a skirt which l5 ' bandrv element is bent to present an outwardly di encircles the upper end of the container above ' rected sealing' flange I0, which extends clear the sealing flange of the. band member and which around the band. ‘ , c . _ is provided at its lower edge with an outwardly 'I'he vertical dimension of theband 1 is such extending sealing flange which mates that of the that the sealing flange Il)V isl located below» the band member, said sealing flange being clamped 20 top edgek of the container.

The cap element Bis. also preferably formed on its underside with an annular groove I4 which registers with-the top edge of the containerandm is adapted to receive a packing gasket or sealing compound I5 forthe purpose of making a tight Y joint. The U-shaped sealing strip 8 tightly embraces the two sealing flanges I0 Vand I2 and serves to hold the cap element tightly sealed.

In thedrawings I-flndicates a container which mayjbe made of »glass or someother vitreous ma on its underside andthefannular-skirt portion Iland also presenting the outwardlyrdirected sealing flange I2 at the bottom' of thefskirt.

YThe edge portion |1 of the blank is.v preferably made of a somewhat larger diameter'> preferably rolled into a bead I8 at the outer edge of the sealing flange I2. This bead and the seal ing flange will extend from one side of the tab I3 around’the cap member` to the other side thereof, the peripheral edge ofthe sealing ñange I2 pro jects outwardly beyond the peripheral edge of the sealing flange Ill. The advantage of this as best Seen in Fig. 3. than the sealing flange Ill on the band, so that construction is that after the sealing strip hasv been removed the projecting edge of the sealing flange I2 can be readily grasped to apply the ‘ Y lIn the operation of sealing a container with a closure embodying my invention, the cap element 6 and the band element 1 will ñrst be assembled necessary lifting force on the cap element to the cap element, the band element and theseal lies the opposite end of the strip and is soldered with their sealing flanges in abutting relation'and 10 loosen it from the container and swing it into its open position.
