Abstract
A first aspect of the present invention relates to a diaphragm (2) for sealing an access opening (5) of a container body (6), the diaphragm being semi-rigid and formed with a shaped cavity (10). The present invention is particularly (but not exclusively) suitable for use with metal cans for packaging foodstuffs. A second aspect of the present invention relates to a reinforcing support (14) for locating over the diaphragm when used to seal an access opening of a container body. A third aspect of the present invention relates to a spoon (26) suitable for use with a container comprising the diaphragm.
Claims19
A diaphragm for a closure for sealing an access opening of a container body, the diaphragm being semi-rigid and formed with an annular region surrounding a shaped cavity.
A reinforcing support for use with a diaphragm, for a closure for sealing an access opening of a container body, the diaphragm being semi-rigid and formed with an annular region surrounding a shaped cavity the reinforcing support comprising an annulus profiled such that it corresponds with and is locatable against all or a substantial part of the annular region of the diaphragm, characterised in that the annulus is hollow in cross-section about all or part of the annulus, the hollow annulus thereby defining an open recess, and a tamper evident band is provided to cover the opening of the recess to thereby define a generally planar surface.
A spoon for use with a container for storing non-liquid material, the spoon comprising a scoop portion for dispensing non-liquid material from the container, wherein the periphery of the scoop portion describes a non-planar surface which is profiled such that when the scoop portion, when overfilled with non-liquid matter, is drawn against the internal periphery of the container, excess non-liquid matter is thereby removed from the scoop portion such that the profile of the non-liquid matter remaining within the scoop portion perpendicular to both the direction of drawing and the longitudinal axis of the scoop portion defines a generally linear ridge.
A container comprising:
- a container body having a sidewall and a base,
- a diaphragm closure for sealing an access opening of the container body, the diaphragm being semi-rigid and formed with an annular region surrounding a shaped cavity, and
- a reinforcing support comprising an annulus profiled such that it corresponds with and is locatable against all or a substantial part of the annular region of the diaphragm, the annulus being hollow in cross-section about all or part of the annulus, the hollow annulus thereby defining an open recess.
