Title:
METAL CONTAINER
Document Type and Number:
WIPO Patent Application WO/2013/167478
Kind Code:
A1
Abstract:
A metal container body 1 comprises a base and a generally cylindrical side wall 3. The top edge of the cylindrical side wall is rolled over to form a hollow annular bead 5 surrounding the upper open end of the container body and a notch 6 is formed at a circumferential point in the annular bead. The container body is for use with a releasable closure 2 formed with an end wall 7 and a depending skirt 8 and having an annular layer of sealing material 9 provided on the inside of the end wall adjacent the skirt. When the closure is pressed onto the container body, the annular bead engages the annular layer of sealing material and some of that material extends into the notch 6. The closure is held on the container only by the partial vacuum formed therein during processing of a food product in the container. After processing, the user opens the container by rotating the closure. Sealing material in the notch forces the closure to lift off from the container to break the seal and release the closure.
