Reclosable metal container
View Patent ↗A reclosable metal container in the style of a bottle-shaped can has a conventional can body of steel or aluminum to which a metal neck component is seamed. A sleeve of plastics fits over the neck component and a detent inside the sleeve clips it onto the seam. The upper edge of the sleeve is fixed in place by a curl on the upper edge of the neck component. By using a separate neck component and hiding the seam under a sleeve, conventional sizes and material gauges can be used for the can body. Thicker material may be used for the neck component in order to withstand necking forces. Threads for closing the container may be provided either on the sleeve or, in an embodiment where the sleeve is simply used to cover the seam, on a cylindrical part of the neck component itself.
1. A reclosable beverage container comprising:
a metal can body having a base and a side wall,
a metal neck component seamed to a free end of the metal can body, the metal neck component formed as a one-piece unit including a generally frusto-conical portion and a cylindrical portion joined to the frusto-conical portion by a shoulder, and
a sleeve which fits over the metal neck component and covers the seam between the neck component and the metal can body;
wherein (i) the sleeve is of a plastics material, and extends over the cylindrical portion of the neck component, the generally frusto-conical portion of the neck component, and a portion of the side wall, (ii) the sleeve is at least partially supported by the seam and the shoulder, and (iii) the sleeve is threaded to allow reclosability of the container.
2. A container as defined in claim 1 , in which the sleeve includes a detent for attaching the sleeve onto the seam.
3. A container as defined by claim 1 , wherein the shoulder is substantially perpendicular to the cylindrical portion.
4. The container as defined in claim 2 , wherein the shoulder is substantially perpendicular to the cylindrical portion.
5. A container as defined in claim 1 , wherein the sleeve is circumferentially continuous.
6. A container as defined in claim 1 , in which the sleeve does not alter flow from the metal container.
