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.
- the invention relates to a method and apparatus suitable for manufacturing such a container.
- GB 2237259 A CMB FOODCAN PLC
- GB 2237259 discloses a diaphragm in the form of peelable foil lidding, the diaphragm peelably bonded to a surface of an intermediate ring component, which is then seamed to the sidewall of a can body.
- any positive pressure within the container acts 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. In the case of containers for food products requiring sterilisation, this positive pressure can arise during processing in a retort.
- a method of forming a container comprising the following steps:
- axial load is meant a load applied generally parallel to the longitudinal axis of the can body.
- the invention takes advantage of the fact that on application of a sufficient (first) 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 radially-expanded region serves the function of preferentially controlling where buckling or collapse of the sidewall will occur.
- US 2003/0113416A1 which uses a complex sequence of forming operations to clamp its diaphragm in place (see FIGS. 8 a - c of US 2003/0113416A1)
- the present invention provides a manufacturing route having fewer process steps and therefore enables higher manufacturing speeds to be achieved.
- the use of the metal of the can body—via the opposing surfaces of the collapsed annular bead—to secure the diaphragm overcomes the tendency of peelable lidding (for example, that of GB 2237259 A) to progressively peel away from its sealing surface when subjected to positive pressures.
- the clamping mechanism used by the invention to secure the diaphragm to the can body 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 resulting from the method 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 can body is conveniently made of aluminium or steel; however, other metals may also be used.
- Steel tinplate has been found to be a particularly suitable material, with trials performed using tinplate of 0.13 mm, 0.15 mm and 0.17 mm wall thickness.
- 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 the can body.
- the diaphragm may also be made from:
- Trials have been performed using diaphragms of 40-90 microns total thickness.
- a diaphragm has been used of 20 microns polypropylene coated onto a 20 micron aluminium substrate.
- paragraph 5 outlines the method of the invention in its broadest form, the method may be refined in various ways as detailed in the following paragraphs . . . .
- steps i & ii are performed substantially simultaneously.
- the invention may be enabled by steps i and ii comprising inserting a flared die within the end of the can body to apply both radial and axial loads to the can body.
- the flared die preferably terminates 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 end of the can body.
- the limit ring is formed integral with the flared die to thereby minimise the number of moving parts.
- radially-extending is meant having a component which extends radially—it is not limited to being purely perpendicular to the longitudinal axis of the can body.
- the radially-extending end face may be curved in profile, progressively deviating radially-outwardly from the longitudinal axis of the can body.
- axially-extending is meant having a component which extends axially.
- the end of the can body is preferably formed with a curl.
- the curl may be formed either before the radial expansion step which forms the circumferential radially-expanded region or subsequently to this step.
- the curl is formed in consequence of steps i and ii comprising inserting a flared die within the end of the can body to apply both radial and axial loads to the can body, the flared die and/or the limit defining an outwardly-curled end face, such that insertion of the flared die into the can body causes the free edge at the end of the can body to propagate along the surface of the outwardly-curled end face to form the curl, formation of the curl limiting further propagation of the free edge such that further insertion of the flared die induces the partial axial collapse of all or part of the circumferential radially-expanded region to form the outwardly-directed open annular bead.
- the curl is flattened against the external surface of the collapsed bead to define a double thickness of metal above and adjacent the external surface of the collapsed bead.
- This flattening (or crushing) of the curl has the benefit of reducing the likelihood of corrosion of the raw edge of metal on the free edge of the can body.
- the method is conveniently adapted during step ii 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 at the end of the can body, wherein simultaneously with or subsequent to step iv the portion is deformed to lie adjacent the exterior surface of the collapsed bead such that the free edge is outwardly-directed.
- the deformed portion does not extend radially-outward of the collapsed bead.
- the flattening described above may be achieved by using a flat plate as referred to above (or other conventional mechanical means).
- the method may be adapted during step ii 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 at the end of the can body, wherein simultaneously with or subsequent to step iv the portion is wrapped around the periphery of the exterior surface of the collapsed bead so that the free edge is directed inwardly towards the can body sidewall.
- the method may be adapted during step ii 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 at the end of the can body, the portion comprising an inner region and an outer region, the inner region extending between the bead and the outer region, the outer region terminating at the free edge, wherein simultaneously with or subsequent to step iv the outer region is folded over the inner region, the combination of inner and outer regions then deformed such that the outer region is sandwiched between the inner region and the exterior surface of the collapsed bead to form a double thickness of metal above and adjacent the external surface of the collapsed bead.
- the portion may be folded back and forth in a succession of folds (for example, in a concertina-like manner), these folds then substantially flattened.
- the method of the invention further comprises applying an upwards load to the underside of the fully collapsed bead to compress and tighten the clamped seal.
- the sidewall of the can body is radially supported at the end of the can body during application of the upwards load to the underside of the fully collapsed bead.
- the diaphragm used in the method of the invention is typically planar
- improved sealability may be obtained by the peripheral annular portion of the diaphragm as located between the opposing surfaces of the open annular bead during step iii comprising an upturned peripheral annular region, with the application of the second axial load during step iv acting to fold over the upturned peripheral annular region to thereby clamp a double thickness of diaphragm material between the opposing surfaces of the collapsed bead.
- the diaphragm includes such an upturned peripheral annular region, it is possible to form the diaphragm profile by starting from a planar metal blank and inclining the periphery of the diaphragm to form the upturned peripheral annular region.
- an apparatus for forming a container having:
- a radial load member for radially expanding the sidewall at an end of a tubular metal can body to define a circumferential radially-expanded region in the sidewall adjacent the end of the can body; ii. a first axial load member for applying a first axial load to the can body, plus a limit ring adapted to limit radial growth of the end of the can body such that during application of the first axial load the circumferential radially-expanded region partially axially collapses to form an outwardly-directed open annular bead; iii. means for locating a peripheral annular portion of a diaphragm between opposing surfaces of the open annular bead; iv.
- a second axial load member for applying a second axial load to the can body to fully axially collapse the bead to thereby clamp the peripheral annular portion of the diaphragm between the opposing surfaces of the bead and close the end of the can body.
- the function of the radial load member and the first axial load member is performed by a flared die terminating in a generally radially-extending end face.
- a flared die has the advantage of enabling the radial expansion of the sidewall and application of the first axial load to be performed virtually simultaneously.
- the limit ring is situated adjacent the radially-extending end face, the limit ring having a generally axially-extending wall to thereby limit radial growth of the end of the can body.
- the flared die and limit ring may be separate components; however, it has been found preferable to combine the flared die and the limit ring into an integrally formed single component.
- the apparatus comprises a flared die, the flared die acting as both the radial load member and first axial load member (in common with the paragraph above).
- the flared die and/or the limit ring define an outwardly-curled end face, such that insertion of the flared die into the can body causes the free edge at the end of the can body to propagate along the surface of the outwardly-curled end face of the die to form a curl.
- FIG. 1 relates to a first embodiment of the invention and shows a cross-section through a tubular can body of uniform diameter and a flared die before any deformation of the can body.
- FIG. 2 is a detail view of part of FIG. 1 , more clearly showing the profile of the flared die.
- FIG. 3 shows a cross-section through the can body and the flared die after the die has been driven within an end of the can body to define an outwardly-directed open annular bead.
- FIG. 4 is a detail view of part of FIG. 3 , more clearly showing the profile of the outwardly-directed open annular bead.
- FIG. 5 is a detail view of the can body prior to full collapse of the annular bead by an axial load member, with a diaphragm located in position between the opposing surfaces of the open annular bead.
- FIG. 6 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.
- FIG. 7 shows a perspective view of the can body after the process steps shown in the earlier figures.
- FIG. 8 relates to a second embodiment of the invention and corresponds to FIG. 6 , but adapted to provide enhanced rigidity and protection against cuts from the free edge at the end of the can body.
- FIG. 9 relates to a further embodiment of the invention, showing an alternative design of flared die/limit ring capable of forming a curl on the end of the can body during the method of the invention.
- FIG. 10 shows the curled can body that results use of the alternative design of flared die/limit ring of FIG. 9 .
- FIG. 11 shows the diaphragm located between the opposing surfaces of the open annular bead of the can body of FIG. 10 , but before inducing full collapse of the bead.
- FIGS. 13 to 15 show the use of a seaming chuck, seaming roll and table to assist in inducing full collapse of the open annular bead and subsequent tightening of the clamped seal that holds the diaphragm in place.
- a tubular 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 FIG. 2 ) which is curved in profile and progressively deviates radially-outwardly from the longitudinal axis 11 of the can body 1 .
- 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 the base 32 of the limit ring (see FIGS. 1 & 2 ).
- the periphery of the radially-extending end face 21 has a diameter corresponding in size to that of the axially-extending wall 31 , so that the limit ring 3 is situated adjacent the end face (see FIG. 2 ). Therefore, there is little or no gap between the periphery of the radially-extending 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), so that the die enters one end of the can body.
- the die 2 and the can body 1 it is within the scope of the invention for either or both of the die 2 and the can body 1 to be driven towards each other; for example, in an alternative embodiment to that shown in the drawings, only one of the die 2 and the can body 1 are moved, the other entity remaining stationary.
- 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 FIG. 3 ).
- 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 FIG. 2 ) 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 to define a circumferential radially-expanded region 14 in the sidewall.
- the die 2 is able to simultaneously apply both axial and radial loads to the can body 1 .
- the free edge 15 of the can body contacts the radially-extending end face 21 of the die (see FIGS.
- the diaphragm 40 is formed from a 20 micron thick aluminium sheet metal substrate coated with a 20 micron thick layer of polypropylene. However, as indicated in the general description of the invention, other materials and thicknesses may be used for the diaphragm 40 .
- a second axial load is applied to the end of the can body 1 by an axial load member in the form of a flat plate 50 (indicated in FIG. 5 ).
- the plate 50 and the can body 1 are moved towards each other (indicated by arrows B in FIG. 5 ).
- Sufficient axial load is applied via the plate 50 to fully axially collapse (or buckle) the outwardly-directed open annular bead 16 a .
- the bead in its fully collapsed state 16 b is shown in FIG. 6 .
- an annular peripheral portion of the diaphragm 40 is clamped between the opposing surfaces of the fully collapsed bead 16 b to seal the end of the can body 1 .
- the force exerted by the plate 50 also results in the portion 17 of the sidewall being flattened 18 to lie adjacent the exterior surface of the collapsed bead 16 b (see FIG. 6 ).
- the flattened portion 17 , 18 does not extend radially-outward of the collapsed bead 16 b , thereby reducing the risk of individuals cutting their fingers on the free edge 15 .
- the flattening of the portion 17 against the exterior surface of the collapsed bead 16 b also results in the clamped diaphragm 40 being recessed a distance ‘h’ beneath the uppermost plane of the can body (see FIG. 6 ). This recessing of the diaphragm provides some protection against impact damage to the diaphragm of the resulting container. 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.
- FIG. 7 The container that results from the above process steps is shown in FIG. 7 , 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 FIG. 7 is adhered to the diaphragm by an adhesive.
- the tab may be riveted to the diaphragm.
- the portion 17 is greater in length than that of the embodiment of FIGS. 1 to 7 . This additional length is necessary to enable the portion 17 to be wrapped around and under 19 the periphery of the exterior surface of the collapsed bead 16 b (as shown in FIG. 8 ), so that the free edge 15 is directed inwardly towards the can body sidewall, thereby providing enhanced rigidity and protection to an individual against cuts from the free edge.
- the design of the flared die 2 and limit ring 3 is adapted to together define an outwardly curled end face 23 (see FIG. 9 ).
- the flared die 2 is driven into the end of the can body 1 to apply both radial and axial loads to the can body to first define the circumferential radially-expanded region 14 . Further insertion of the die 2 into the can body 1 causes the free edge 15 at the end of the can body to propagate along the surface of the outwardly-curled end face 23 to form curl 50 (see FIG. 10 ).
- the curl 50 forms to such an extent that the free edge 15 opposes and contacts the outside of the sidewall 13 , which thereby inhibits further movement of the free edge.
- further insertion of the flared die 2 induces the partial axial collapse of all or part of the circumferential radially-expanded region 14 to form the outwardly-directed open annular bead 16 a .
- FIG. 10 shows the curl 50 and outwardly-directed open annular bead 16 a that results from use of the flared die 2 and limit ring 3 of FIG. 9 .
- FIG. 11 shows the diaphragm 40 located between the opposing surfaces of the outwardly-directed open annular bead 16 a before full collapse of the bead.
- the can body 1 is then rotatably mounted on a seaming chuck 60 (see FIGS. 12 & 13 ).
- the seaming chuck 60 includes a circumferential axial wall section 61 and a circumferential tapered wall section 62 .
- the axial wall section 61 of the chuck is inserted into the end of the can body 1 to radially support the sidewall 13 , with the tapered wall section 62 nestling against the top of the curl 50 .
- the opposite end of the can body 1 is supported on a table 63 (see FIG. 12 ). In use, the table 63 is driven upwards (indicated by arrows C on FIGS.
- FIGS. 12 & 13 The resulting can body 1 with the fully collapsed bead 16 b is shown in FIGS. 12 & 13 .
- seaming roll 64 having a tapered surface 65 is then brought into contact with the underside of the collapsed bead 16 b whilst the can body 1 is rotated about longitudinal axis 11 (see FIGS. 14 & 15 ).
- the direction of rotation of the can body 1 and seaming roll 64 is indicated by arrows in FIGS. 14 & 15 .
- the curl 50 may be flattened against the external surface of the collapsed bead 16 b to define a double thickness of metal above and adjacent the external surface of the collapsed bead.
- this flattening (or crushing) of the curl would be achieved through the table 63 being urged further upwards to deform the curl 50 between the opposing surfaces of the tapered wall section 62 of the chuck 60 and the tapered surface 65 of the seaming roll 64 .
