Definitions

  • This invention relates to a container in the form of a metal can body having an access opening closed with a flexible diaphragm, the container provided with an improved means of securing the diaphragm to the can body.
  • metal containers having a can body provided with an access opening which is sealed by a flexible diaphragm in the form of lightweight peelable foil lidding.
  • the diaphragm typically includes a metal substrate to perform the functions of providing strength, forming a barrier to mitigate loss of moisture and flavours from the filled can, and preventing contamination.
  • Heat sealing or adhesive are commonly used to provide a peelable bond between the diaphragm and the can body.
  • the diaphragm is typically bonded to an intermediate ring component, which is then seamed to the sidewall of the can body.
  • GB 2237259 A (CMB FOODCAN PLC) 01.05.1991 discloses a typical example of such a known metal container, with the diaphragm peelably bonded to an intermediate metal ring.
  • a problem common to such known containers having a peelable flexible diaphragm is that positive pressure within the container will act to cause the diaphragm to progressively peel itself away from the surface to which it is bonded. This progressive peeling initiates and propagates from inside the container and is therefore invisible to the can manufacturer, the filler and end-consumer. For this reason, when considering the case of containers for food products requiring sterilisation, such containers must either:
  • a problem specific to the use of an intermediate ring component is that its manufacture results in material wastage because the ring is cut from a sheet of metal, with the central cut-out portion being thrown away.
  • a container comprising a tubular metal can body and a diaphragm, the sidewall of the can body comprising a circumferential radially-expanded region located at one or both ends of the can body, wherein an outwardly-directed collapsed annular bead is provided in the expanded region, characterised in that the diaphragm is clamped between opposing surfaces of the collapsed bead to close the end of the container.
  • the use of the metal of the can body - via the opposing surfaces of the collapsed annular bead - to secure the diaphragm by clamping overcomes the tendency of peelable lidding to progressively peel away from the container when subject to positive pressures.
  • the clamping mechanism used by the invention to close the container ensures that the diaphragm can sustain both negative and positive pressures in a better manner than conventional peelable lidding. Therefore, considering the case of containers for food products requiring sterilisation, the container of the invention may be processed within a larger range of retorts with a reduced need for pressure balancing.
  • clamping to secure the diaphragm also avoids the use of adhesive, heat sealing or other sealing compounds, and therefore simplifies the manufacturing route for the container of the invention compared to containers provided with conventional peelable lidding.
  • the invention can deliver good seal integrity without the use of sealing compound, improved sealability is provided when using a sealing compound at the interface between the diaphragm and the opposing surfaces of the collapsed bead.
  • the invention does not require the use of the intermediate ring component commonly used in the manufacture of containers closed with peelable lidding (see GB 2237259 A ), and therefore results in material cost savings and a simplified manufacturing route.
  • the metal can body is conveniently made of aluminium or steel; however, other metals may also be used.
  • the diaphragm is conveniently made from foil sheet metal, thereby providing flexibility and reduced weight relative to conventional generally rigid sheet metal can ends that are seamed onto can bodies.
  • the diaphragm may also include one or more polymer coatings/films on either or both faces of a metal substrate. The use of such polymer coatings/films may provide a suitable surface for printing of text/graphics and protect the metal substrate from corrosion.
  • the polymer coating/film material would act like a gasket when clamped between the opposing surfaces of the collapsed bead, with its resilience enabling it to deform and adapt to the profile of the opposing bead surfaces, thereby helping to develop and maintain a hermetic seal between the diaphragm and can body.
  • the diaphragm may also be made from:
  • a portion of the sidewall of the can body extending between the collapsed bead and a free edge of the can body is flattened to lie against the exterior surface of the collapsed bead to provide protection against cuts from the free edge.
  • This flattening results in the diaphragm being, in effect, recessed beneath a double thickness of the material of the can body sidewall.
  • the portion may incorporate one or more folds (for example, in a concertina-like manner) which are flattened to lie against the exterior surface of the collapsed bead. This would further enhance container rigidity and protection for the diaphragm.
  • a portion of the sidewall of the can body extending between the collapsed bead and a free edge of the can body , wherein the portion is wrapped around and under the periphery of the exterior surface of the collapsed bead so that the free edge is directed radially inwardly to oppose the exterior surface of the can body sidewall.
  • the diaphragm comprises a score line defining an opening area, and a tab for severing the score line.
  • a method of forming a container comprising the following steps:
  • the invention takes advantage of the fact that on application of a sufficient axial load to the can body, the sidewall of the can body will buckle (or collapse). Formation of the circumferential radially-expanded region in the sidewall provides a region that is highly susceptible to buckling or collapse on application of sufficient axial load. Therefore, the expanded region serves the function of preferentially controlling where buckling or collapse of the sidewall will occur.
  • axial load is meant a load applied generally parallel to the longitudinal axis of the can body.
  • steps i & ii are performed substantially simultaneously.
  • the invention may be enabled by steps i and ii comprising inserting a flared die within one or both ends of the can body to apply both radial and axial loads to the can body, the flared die terminating in a generally radially extending end face, a limit ring situated adjacent the end face, the limit ring having a generally axially extending wall to thereby limit radial growth of the free edge of the can body. It is anticipated that the method would work as follows:
  • the method may be modified so that during step ii the circumferential radially-expanded region is formed to leave a portion of the sidewall of the can body extending between the partly collapsed outwardly-directed open annular bead and the free edge, wherein simultaneously with or subsequent to step iv the portion is flattened to lie against the exterior surface of the collapsed bead.
  • This flattening may be achieved by using a flat plate as referred to above (or equivalent mechanical means).
  • the portion may be folded back and forth in a succession of folds (for example, in a concertina-like manner), these folds then flattened against the exterior surface of the collapsed bead.
  • step ii the circumferential radially-expanded region is formed to leave a portion of the sidewall of the can body extending between the partly collapsed outwardly-directed open annular bead and the free edge, wherein simultaneously with or subsequent to step iv the portion is folded around and under the periphery of the exterior surface of the collapsed bead so that the free edge is directed radially inwardly to oppose the exterior surface of the can body sidewall.
  • an apparatus for forming a container having:
  • a common entity is used to simultaneously both radially expand the sidewall (see i) and apply the first axial load (see ii).
  • the common entity is a flared die, the flared die terminating in a generally radially extending end face, wherein the means to limit radial growth is a limit ring situated adjacent the end face, the limit ring having a generally axially extending wall to thereby limit radial growth of the free edge of the can body.
  • the flared die and limit ring may be separate components; however, it has been found preferable to combine the flared due and the limit ring into an integrally formed single component.
  • FIGURE 1a relates to a first embodiment of the invention and shows a cross-section through a can body of uniform diameter and a flared die before any deformation of the can body.
  • FIGURE 1b is a detail view of figure 1a , more clearly showing the profile of the flared die.
  • FIGURE 2a shows a cross-section through the can body and the flared die after the die has been driven within one end of the can body to define an outwardly-directed open annular bead.
  • FIGURE 2b is a detail view of figure 2a , more clearly showing the profile of the outwardly-directed open annular bead.
  • FIGURE 3 is a detail view of the can body prior to full collapse of the annular bead by a flat plate, with the diaphragm located in position between the opposing surfaces of the open annular bead.
  • FIGURE 4a shows a cross-section through the can body in its final form, with the bead in its fully collapsed state to clamp the diaphragm in position between opposing surfaces of the bead.
  • FIGURE 4b is a detail view corresponding to figure 4a , but inverted relative to figure 4a .
  • FIGURE 5 shows a perspective view of the can body after the process steps shown in the earlier figures.
  • FIGURE 6 relates to a second embodiment of the invention and corresponds to figure 4b , but adapted to provide enhanced rigidity and protection against cuts from the free edge than the first embodiment of the invention.
  • a cylindrical metal can body 1 of uniform diameter is initially located with one end co-axial with a flared die 2 and limit ring 3.
  • the flared die 2 terminates in a generally radially extending end face 21 (see figure 1 b) which is curved in profile.
  • the flared die 2 locates within a recess provided in the limit ring 3, the recess defined by a generally axially extending wall 31 extending upwardly from base 32 of the limit ring (see figures 1 a & 1 b).
  • the periphery of the end face 21 has a diameter corresponding in size to that of the axial wall 31 (see figure 1 b) . Therefore, there is little or no gap between the periphery of the end face 21 and the axially extending wall 31.
  • the flared die and the limit ring would be integrally formed.
  • the flared die 2 and can body 1 are driven towards each other along the longitudinal axis 11 of the can body (indicated by arrows A and A), so that the die enters one end of the can body.
  • a forming operation is performed on the opposite end of the can body 1 (by means not shown), to provide a flare 12 (as indicated in figure 2a ).
  • the flare 12 enables a conventional sheet metal can end to be seamed to that opposite end of the can body 1.
  • the flared walls 22 (see figure 2b ) of the die act against the sidewall 13 of the can body, thereby progressively radially-expanding the sidewall adjacent the end of the can body.
  • the die 2 is able to simultaneously apply both axial and radial loads to the can body 1.
  • the free edge 14 of the can body contacts the end face 21 of the die, with further insertion of the die leading to radial growth of the free edge until constrained by the axially extending wall 31 of the limit ring 3.
  • the flared die 2 is then removed to allow insertion of a diaphragm 40 between the opposing surfaces of the outwardly-directed open annular bead 15a (see figure 3 ).
  • the diaphragm 40 is formed from sheet metal, such as aluminium.
  • a second axial load is applied to the end of the can body 1 by means of a flat plate 50 (indicated in figure 3 ).
  • the plate 50 and the can body 1 are moved towards each other (indicated by arrows B in figure 3 ).
  • just one of the plate 50 and can body 1 is moved.
  • Sufficient axial load is applied via the plate 50 to fully axially collapse (or buckle) the outwardly-directed open annular bead 15a.
  • the bead in its final fully collapsed state 15b is shown in figures 4a & 4b .
  • the periphery of the diaphragm 40 is clamped between the opposing surfaces of the fully collapsed bead 15b to seal the end of the can body 1.
  • the force exerted by the plate 50 also results in the portion 16 of the sidewall being flattened 17 to lie against the exterior surface of the collapsed bead 15b (see figure 4b ). This ensures that the free edge 14 does not protrude and cause a cut hazard to individuals.
  • the flattening of the portion 16 against the exterior surface of the collapsed bead 15b also results in the clamped diaphragm 40 being recessed a distance 'h' beneath the uppermost plane of the can end (see figure 4b ). Furthermore, the flattening also results in a triple thickness of can body sidewall material at that end of the can body 1, with consequent benefits to container rigidity.
  • the container that results from the above process steps is shown in figure 5 , showing the can body 1 with the diaphragm 40 clamped in position to close one end of the can body.
  • the diaphragm is formed with a score line 41 to define a prearranged opening area for dispensing of the container's contents, with a tab 42 for opening of the prearranged opening area by severing of the score line.
  • the tab shown in figure 5 is adhered to the diaphragm by an adhesive.
  • the tab may be riveted to the diaphragm.
  • the portion 16 is greater in length than that of the embodiment of figures 1 to 5 . This additional length is necessary to enable the portion 16 to be flattened 17 and wrapped around and under 18 the periphery of the exterior surface of the collapsed bead 15b (as shown in figure 6 ), so that the free edge 14 is directed radially inwardly to oppose the exterior surface of the can body sidewall, thereby providing enhanced rigidity and protection against cuts from the free edge.
