Definitions

• This invention relates to a reclosable metal container such as a can of steel or aluminium.
• a bottle- shaped can for packaging beverages So-called "bottle cans" have been proposed in patent applications such as JP-A-2003165539 , for example, in which a container body is closed at one end by a can end seamed to the body to form a base, and at the opposite end is necked inwardly to form a shoulder . A portion of the can body extends away from the free edge of the shoulder into a cylindrical portion -which is threaded so as to be closed by a screw closure.
• Alternative proposals for bottle cans use plastic collets to provide a thread for reclosing the can instead of threading the metal neck.
• US-A-2, 864, 529 describes an ovezrcap for a metal containers having a cone or raised top, the overcap covering a seam which joins the cone to the body of the container.
• DE 29980137 U describes a plastic component which covers the seam between a neck component and a can body.
• JP 10 167356 A describes a shoulder cover for fixing a cap which is removeably mounted on a container body.
• Necking of the container body sufficiently to provide a neck finish for reclosing may involve up to 56 necking stages. Because of its mater-ial properties, this is not usually possible if the container is made of steel of conventional thickness (for example 0.08 mm).
• a reclosable container comprising a metal can body having a base and a side wall, a metal neck component seamed to a free end of the can body, the neck component comprising a generally frustoconical shoulder portion and a cylindrical portion, the container further comprising a sleeve which fits over the metal neck component and covers the seam between the neck component and can body; characterised in that the sleeve is of plastics material, extends over the cylindrical portion of the neck component and is threaded to allow reclosability of the container.
• the can body is typically a standard beverage can body which can be mass-produced using regular beverage can manufacturing lines. Different neck finishes can be offered by a range of neck components and plastic sleeves.
• the can body may be made from steel or aluminium of thin gauges such as 0.1 mm for aluminium, 0.08 mm for steel .
• the neck component may be of thicker material and provides barrier properties to prevent, for example, passage of gas which may affect the product in the container .
• the sleeve includes a detent for fixing the sleeve onto the seam.
• This detent provides a seal to prevent water ingress.
• the open end of the sleeve may be retained by a curl on the neck component.
• the can body has a small necked-in region at the end to which the neck component is seamed.
• the sleeve may extend over this region on the can body so as to fit against the can body side wall and resist water ingress.
• the sleeve may be profiled so as to correspond to the shoulder shape on a conventional plastic bottle.
• the neck component includes a support region between the frustoconical and cylindrical portions.
• FIG. 1 is a schematic side section of a first embodiment of container according to the invention
• Figure 2 is an enlarged side section of the shoulder and neck region of the container of figure 1.
• Figure 1 shows a container comprising a can body 1, neck component 10 and sleeve 20.
• the can is a typical beverage can body comprising a side wall 2, necked at its upper end 3 , and an integral domed base 4.
• the can body is made of sheet metal, typically steel or aluminium in the range of 0.25 mm to 0.35 mm thick with walls reduced in thickness during manufacture.
• Neck component 10 comprises a metal support having a generally frustoconical part 11 and a cylindrical portion 12. As best shown in figure 2 , a second cylindrical portion 13 is joined to the first cylindrical portion by a shoulder 14. The neck component terminates in a flange or, ideally, curl 15 at its upper end which holds the plastic sleeve 20 in position. The sleeve thus also hides the cut edge of the neck component. At its lower end the neck component is fixed by a double seam 16 to the can body 1. If the container is closed by a plastics closure having a bore seal, the bore seal will impart further cut edge protection.
• the sleeve 20 has a curved sheath 23 with a hook- shaped detent 21 which clips onto the seam 16. Annulus 22 provides further location of the sleeve over the seam.
• the sleeve of figures 1 and 2 is thus fixed in position by the detent 21 and neck component flange 15.
• the sleeve 20 has a cylindrical upper portion 24 which is threaded 25. Below thread 25 the upper portion includes a neck support ring 26 for handling purposes .
• the sleeve may be shaped so as to blend into the side wall of the can body.
• the sleeve may be made of thin plastics so that extra support for the curved shape is provided by shoulder 14 of the neck component.
