Definitions

  • This invention relates to a pressure adjustable container and more particularly to polyester containers capable of being filled with hot liquid, and an improved side wall construction for such containers.
  • Thermal stress is applied to the walls of the container upon introduction of hot fluid.
  • the hot fluid will cause the container walls to soften and then shrink unevenly, causing distortion of the container.
  • the polyester must therefore be heat-treated to induce molecular changes resulting in a container that exhibits thermal stability.
  • U.S Pat No. 4,497,855 discloses a container with a plurality of recessed collapse panels, separated by land areas, which allows uniformly inward deformation under vacuum force. The vacuum effects are controlled without adversely affecting the appearance of the container. The panels are drawn inwardly to vent the internal vacuum and so prevent excess force being applied to the container structure, which would otherwise deform the inflexible post or land area structures. The amount of 'flex' available in each panel is limited, however, and as the limit is approached there is an increased amount of force that is transferred to the side walls.
  • EP 0505054 upon which the preamble of Claim 1 is based, proposes a partial solution to this problem by using a continuous integral hinge structure that surrounds the panel.
  • Hayashi et al US Pat No. 4,877,141, discloses a panel configuration that accommodates an initial, and natural, outward flexing caused by internal hydraulic pressure and temperature, followed by inward flexing caused by the vacuum formation during cooling.
  • the panel is kept relatively flat in profile, but with a central portion displaced slightly to add strength to the panel but without preventing its radial movement in and out.
  • the amount of movement is limited in both directions.
  • panel ribs are not included for extra resilience, as this would prohibit outward and inward return movement of the panel as a whole.
  • U.S. Pat 5,908,128 discloses another flexible panel that is intended to be reactive to hydraulic pressure and temperature forces that occur after filling.
  • Relatively standard 'hot-fill' style container geometry is disclosed for a 'pasteurizable' container. It is claimed that the pasteurization process does not require the container to be heat-set prior to filling, because the liquid is introduced cold and is heated after capping.
  • Concave panels are used to compensate for the pressure differentials. To provide for flexibility in both radial outward movement followed by radial inward movement however, the panels are kept to a shallow inward-bow to accommodate a response to the changing internal pressure and temperatures of the pasteurization process.
  • U.S. Pat 5,303,834 discloses still further 'flexible' panels that can be moved from a convex position to a concave position, in providing for a 'squeezable' container. Vacuum pressure alone cannot invert the panels, but they can be manually forced into inversion. The panels automatically 'bounce' back to their original shape upon release of squeeze pressure, as a significant amount of force is required to keep them in an inverted position, and this must be maintained manually. Permanent deformation of the panel, caused by the initial convex presentation, is avoided through the use of multiple longitudinal flex points.
  • U.S. Pat 5,971,184 discloses still further 'flexible' panels that claim to be movable from a convex first position to a concave second position in providing for a grip-bottle comprising two large, flattened sides.
  • Each panel incorporates an indented 'invertible' central portion.
  • Containers such as this whereby there are two large and flat opposing sides, differ in vacuum pressure stability from hot-fill containers that are intended to maintain a generally cylindrical shape under vacuum draw.
  • the enlarged panel side walls are subject to increased suction and are drawn into concavity more so than if each panel were smaller in size, as occurs in a 'standard' configuration comprising six panels on a substantially cylindrical container.
  • such a container structure increases the amount of force supplied to each of the two panels, thereby increasing the amount of flex force available.
  • the panels cannot then return back to their original convex position again upon release of vacuum pressure when the cap is removed if there is any meaningful amount of convexity in the panels.
  • a panel will be subject to being 'force-flipped' and will lock into a new inverted position. The panel is then unable to reverse in direction as there is no longer the influence of heat from the liquid to soften the material and there is insufficient force available from the ambient pressure. Additionally, there is no longer assistance from the memory force that was available in the plastic prior to being flipped into a concave position.
  • Pat 5,908,128 previously disclose the provision of longitudinal ribs to prevent such permanent deformation occurring when the panel arcs are flexed from a convex position to one of concavity. This same observation regarding permanent deformation was also disclosed in Krishnakumar et al U.S. Pat 5,303,834. Hayashi et al US Pat No. 4,877,141 also disclosed the necessity of keeping panels relatively flat if they were to be flexed against their natural curve.
  • the present invention in contrast, allows for increased flexing of the vacuum panel side walls so that the pressure on the containers may be more readily accommodated. Reinforcing ribs of various types and location may still be used, as described above, to still compensate for any excess stress that must inevitably be present from the flexing of the container walls into the new 'pressure-adjusted' condition by ambient forces.
  • the regions project in an outward direction relative to the plane.
  • the regions project in an inward direction relative to the plane.
  • the flex panel may be substantially arcuate.
  • the flex panel may include two flexible panel portions meeting at an apex.
  • the flex panel may be located between relatively inflexible land areas.
  • the or each initiator portion may be located substantially at an end of said flex panel.
  • the initiator portion may be located substantially towards a centre of said flexible panel.
  • the or each initiator portion may include a substantially flattened portion.
  • the flattened portion may be located at a distal end of said initiator portion relative to the rest of the flexible panel.
  • the or each initiator portion may project in an opposite direction to the remainder of the flexible panel.
  • a boundary between said initiator portion and the remainder of said flexible panel may be substantially arcuate in the circumferential direction of the panel.
  • the extent of projection of the flexible panel may progressively increase away from said initiator portion.
  • the extent of projection of the flexible panel may remain substantially constant away from said initiator portion.
  • the container may include a connector portion between said flexible panel and said land areas, the connector portion adapted to locate said flexible panel and said land areas at a different circumference relative to a centre of the container.
  • the connector portion may be substantially "U"-shaped, wherein the side of the connector portion towards the flexible panel is adapted to flex, substantially straightening the "U"-shape when the flex panel is in a first position and return to the "U"-shape when the flex panel is inverted from the first position.
  • the extent of projection of the initiator portion may be adapted to allow deflection of the initiator portion upon cooling of a predetermined liquid introduced to the container at a predetermined temperature.
  • the flex panel may be adapted to invert in use upon deflection of the initiator portion.
  • a container is indicated generally at 1 as having a main side wall portion 2 of generally round cylindrical shape.
  • the container 1 is a pressure-adjustable container, in particular a 'hot-fill' container that is adapted to be filled with a liquid at a temperature above room temperature.
  • the container 1 may be formed in a blow mould and may be produced from a polyester or other plastic material, such as a heat set polyethylene terepthalate (PET).
  • PET polyethylene terepthalate
  • the lower part of side wall portion 2 includes a plurality of vertically oriented elongated vacuum panels 3 which are disposed about the circumference of the container, spaced apart from one another by smooth vertically elongated land areas 4. Each panel may be generally rectangular in shape and is adapted to flex inwardly upon filling the container with a hot-fill liquid, capping the container, and subsequent cooling of the liquid. During the process the vacuum panels 3 operate to compensate for the hot-fill vacuum.
  • the vacuum panel 3 includes at least one connecting portion 7 that connects a projecting portion 5 to the land areas 4.
  • the projecting portion 5 includes an initiator portion 8, which controls a junction of the projecting portion 5 and the connecting portion 7.
  • the connecting portion 7 is capable of flexing inwardly under vacuum force with relative ease and the initiator portion 8 causes the projecting portion 5 to deflect by both inverting and then flexing further inwardly. This causes far greater evacuation of volume from the vacuum panels 3 than existing flex-panels. Vacuum pressure is subsequently reduced to a greater degree than in existing containers causing less stress to be applied to the container side walls.
  • the connecting portion 7 allows for the radius from the centre of the container 1 at the edge of the flex panel 3 (inside of the connecting portion 7) to be set independently of the radius at the edge of the land areas 4 (outside border surrounding the connecting portion 7).
  • the connecting portion 7 allows for the land area 4 to be independently complete on one side, and for the flex panel 3 to be complete, and optimised for deflection on the other side.
  • the connecting portion 7 bridges any circumferential radial difference between the two structures.
  • the boundary 8A between the initiator portion 8 and the rest of the projecting portion 5 is shown as being itself substantially arcuate in the circumferential direction of the panel 3.
  • the amount of arc or projection of the initiator portion 8 relative to a plane defined by the central longitudinal axis of the container is significantly less than the arc or projection of the projecting portion 5, making it more susceptible to vacuum pressure.
  • the initiator portion 8 further includes an initiator end 9 that is predominantly flattened, and is most susceptible to vacuum pressure.
  • the vacuum panel 3 may flex at initiator end portion 9 followed by deflection and then inversion of the whole initiator portion 8 and subsequent continuation of inversion of the projecting portion 5.
  • the initiator end 9 may be concave. In this embodiment however, the extent of projection of the concave portion relative to a plane defined by the central longitudinal axis of the container is still less than the magnitude of the projection of the rest of the projecting portion 5.
  • the inversion of the projecting portion 5 may progress steadily in response to the gradual contraction of the volume of the contents of the container 1 during cooling. This is in contrast to a panel which 'flips' between two states.
  • the gradual deflection of the projecting portion 5 to and from inversion in response to a relatively small pressure differential in comparison to panels which "flip" means that less force is transmitted to the side walls of the container 1. This allows for less material to be necessarily utilised in the container construction, making production cheaper. Consequentially, less failures under load may occur for the same amount of container material.
  • the reduced pressure differential required to invert the projecting portion 5 allows for a greater number of panels 3 to be included on a single container 1.
  • the panel 3 also does not need to be large in size, as it provides for a low vacuum force to initiate panel flex.
  • the panels 3 do not need to be large in size, nor reduced in number on a container structure, providing more flexibility in container design.
  • Figure 2b shows a cross-section along line DD in Figure 2a.
  • the panel 3 is shown with projecting portion 5 in its non-inverted position, the dotted line indicating the boundary of the projecting portion 5 with the connecting portion 7.
  • the projecting portion 5 is substantially arcuate in an outwardly radial or transverse direction, as indicated by direction arrow 6.
  • the connector portion 7 is substantially "U"-shaped, with the relative heights of the sides of the "U” determining the relative radius at which the land areas 4 and projecting portion 5 are positioned.
  • the initiator end 9 is most susceptible to vacuum pressure due to projecting to the least extent i.e. having the smallest arc of the projecting portion 5.
  • Figure 3 shows a panel 3 with the projecting portion 5 inverted due to applied vacuum pressure.
  • the initiator end 9 and initiator portion 8 deflect and invert first, effectively pulling the adjacent area of the projection portion 5 inwards. This continues along the projecting portion 5 until the projecting portion is fully inverted as shown at 5b.
  • the dotted line in Figure 3 shows the edge of the projection portion 5 and the dashed line 5a shows the position of the projecting portion 5 when not inverted.
  • the panel 3 when the vacuum pressure is released following removal of the cap from the container, the panel 3 is able to recover from its vacuum-set position and return to its original configuration. This may be assisted by an even gradation of arc curvature from one end of the projecting portion 5 to the other, the arc of curvature progressively increasing away from the initiator portion 8.
  • the initiator portion 8 causes the inwardly arcuate panel 3 to successfully reverse direction transversely, beginning with reversal of the initiator portion 8 and followed by the raised projecting portion 5 without being subject to non-recoverable buckling.
  • the vacuum panel 3 may repeatedly invert without significant permanent deformation.
  • Figures 4a-c show cross-sectional representations of the container 1 shown in Figure 1 along lines AA, BB, and CC respectively with the projecting portions 5 in the non-inverted position.
  • the projecting portion 5 progressively projects further outward away from the initiator portion 8.
  • Figures 5a-c show cross-sectional representations of the container 1 along lines AA, BB, and CC respectively with the projecting portion 5 in the fully inverted position, 5b, due to applied vacuum pressure.
  • the area of the projecting portion 5 around line AA deflects to a relatively large extent in comparison to areas closer to the initiator portion 8.
  • the dotted lines 5a in Figures 5a-c indicate the position of the projection portions 5 without vacuum pressure.
  • Figure 6a shows an elevation of an alternative embodiment of a vacuum panel 30 with initiator portion 80 and flattened region 90.
  • the connector portion 70 of vacuum panel 30 is a planar member surrounding the projecting portion 50.
  • Figure 6b shows the vacuum panel 30 without vacuum pressure applied.
  • the projecting portion 50 has a substantially constant arc curvature away from the initiator region 80 in the direction of arrow 6.
  • Figure 6c shows vacuum panel 30 with its projecting portion 50 in a fully inverted position due to the application of vacuum pressure.
  • Figure 7a shows an elevation of a further alternative embodiment of a vacuum panel 300.
  • the vacuum panel 300 includes two projecting portions 500 located vertically adjacent to each other.
  • the initiator portion 800 extends in two directions from a central initiator end 900.
  • the centre of the vacuum panel 300 is most susceptible to deflection under vacuum pressure and hence deflects first.
  • Figures 7b and 7c show the vacuum panel 300 without vacuum pressure applied and in the fully inverted position respectively.
  • Dotted line 800a illustrates the arcuate boundary between the initiator portions 800 and the rest of the projecting portions 500.
  • FIG 8a shows an elevation of a further alternative embodiment of a vacuum panel referred generally by arrow 300 1 .
  • the vacuum panel 300 1 includes two projecting portions 500 1 and 500 11 located vertically adjacent to each other with respective initiator portions 800 1 including a central flattened region 900 1 , between them.
  • the nominal position of one of the projecting portions 500 11 is concave rather than convex (see Figure 8b).
  • the concave projecting portion 500 11 is inverted in the direction shown by arrow 6a (see Figure 8c), reducing pressure on land areas (4) between adjacent panels 300 1 .
  • vacuum pressure causes both projecting portions 500 1 and 500 11 to invert in the direction of arrow 6B. (See Figure 8d).
  • the container (1) may have vacuum panels with projecting portions 5 1 including two planar portions 10 meeting at an apex 11 so as to form an angular, as opposed to an arcuate, panel.
  • Figures 9a-c show cross-sections along lines AA, BB and CC respectively of the container 1 of Figure 1 but with such projecting portions 5 1 .
  • Figures 9d-f show the inverted positions of projecting portions 5 1 of Figures 9a-c respectively, with the full lines 5 1 b showing the inverted position and the dotted lines 5 1 a the positions before inversion.
  • the panels 3 of any of the embodiments may be disposed transversely of the longitudinal axis of the container 1 rather than vertically as shown in Figure 1 for example.
  • a pressure adjustable container including flexible panels that allow for a large change in volume in the contents of the container and therefore reduced pressure being applied to the side walls. Consequently, reduced material content is required to support the integrity of the container and the container may thus be cheaper to manufacture.
