Definitions

  • the present invention is generally directed to containers, and in particular to containers having a fracturable opening arrangement.
  • the Applicant has developed a container that can be opened using a fracturable arrangement which produces a fracture within the wall of the container. This fracture produces an opening for the container through which the contents of the container can be discharged.
  • This container is described in the Applicants' international Publication No. WO 2012/120344, details of which are incorporated herein by reference.
  • the resultant opening provided by the container follows the fracture produced in the container wall. This fracture occurs along a recessed groove provided within the wall of an intermediate portion of the container. The fracture occurs along the base portion of the recessed groove. This results in a lip extending along or adjacent the periphery of the container opening produced by the fracture. This lip is generally inwardly directed towards the middle of the resultant container opening.
  • a problem associated with this inwardly directed lip is that it partially blocks the flow of the contents passing through the container opening thereby preventing the free flow of the contents from the container. This is regardless of whether the contents are a liquid or a powder or granular product.
  • the inwardly directed lip will act to interfere with the flow of the contents by limiting the size of the container opening thereby restricting the flow of the container contents being poured out of that container. Portions of the contents can also become trapped behind the lip making it difficult to pour ail of the contents out of the container at one time. It is often necessary to shake the container to release all of the remaining contents from behind the lip. While surfactants can be used to improve the flow from the container, this does not resolve the issues associated with the presence of the inwardly directed lip.
  • the present invention provides a container including: an elongate body having a first section and a second section, and an intermediate section located between the first and second portions thereof; the body including a shell portion providing a cavity for accommodating a dispensable product, and a cover portion for covering the cavity, the shell portion including a peripheral flange, the cover portion being secured to the flange;
  • fracturable arrangement located at the intermediate section of the body, the fracturable arrangement including an outwardly directed rib extending along an at least substantially lateral plane about the shell portion relative to an elongate axis of the body;
  • outwardly directed used in relation to the rib is defined herein to mean that the rib projects externally from the intermediate section of the container body and is therefore outwardly directed away from the rest of the intermediate portion.
  • the outwardly directed rib may be integrally formed together with the shell portion.
  • the shell portion may preferably be manufactured using a thermoforming process, and may preferably be made of a polymer material such as, for example, polyethylene terephthalate (PET), polyvinyl chloride (PVC), styrene, polypropylene (PP), nylon or other thermoformable material. It is however also envisaged that the shell portion be mechanically formed from a foil material such as aluminium.
  • the wall thickness of the outwardly directed rib may preferably be substantially identical to the average wall thickness of the shell portion. The forming of the rib is not intended to provide a weakened area within the container. Rather, the rib provides an area where a fracture can be
  • the polymer material forming the rib has sufficient material rigidity to allow for the formation and propagation of the fracture along the rib.
  • the outwardly extending rib extends along a said lateral plane, and a cross section of the rib taken in a plane perpendicular to the lateral plane shows the perpendicular cross-sectional profile of the rib.
  • the rib may be formed from two opposing wall sections that join together at a join area forming a periphery of the rib. The two opposing wall sections may define an included angle
  • the included angle may be equal to or between 0 and 180 degrees, whereby the opposing wall sections are parallel relative to each other at 0 degrees, and whereby the opposing wall sections are in the same general plane at 180 degrees, and the rib has a flat profile.
  • the opposing wall sections of the rib may be joined with a relatively sharp transition between the two wall sections at the join area. Therefore the perpendicular cross-sectional profile of the outwardly extending rib may be substantially 'V in shape.
  • a radius may be provided at the join area between the opposing walls of the rib so that the opposing walls are joined with a relatively smooth transition between the two wall sections at the join area.
  • the perpendicular cross-sectional profile of the rib may then be substantially [ U' in shape. The use of a V shaped profile acts to concentrate the stress applied to the rib at the join area.
  • the perpendicular cross- sectional profile of the rib determines the stress concentration in the bent material inner surface as it is straightened out. This allows for control of the force required to open the container through a fracture in this area. A sharper V profile will require less force to start a fracture in the surface than a rounded profile. This enables more fracture resistant materials to be fractured more easily. Conversely if a materia! is too easily fractured by this method then the V profile may be more rounded or arcuate and the resulting force to create the opening is increased. This is analogous to creasing a flat material to produce a break. Tougher materials will require a sharper crease to fracture. Brittle materials wiil require less of sharp crease to effect a fracture.
  • the equation characterises the stress applied to the rib and refers to a neutral axis about which the moment generated by the abovementioned angular displacement is applied.
  • This neutral axis extends parallel to the lateral plane extending through the rib.
  • the position of the neutral axis will vary depending on the cross-sectional shape of the rib taken along the lateral plane extending through the rib.
  • the lateral cross-sectional shape of the rib taken along the lateral plane extending through the rib may be substantially V in shape.
  • the rib has a tip area, and two arms extending from the tip area and extending around the shell portion to opposing ends thereof, which may be located at the flange of the shell portion.
  • the neutral axis may be located relative to the rib such that moment applied by the angular displacement results in tensile stresses being applied to the tip area and immediately adjacent areas of the arms extended from the tip area. Compressive stresses may however be applied to the opposing ends of the rib adjacent the flange of the shell portion.
  • the fracture point may be located in the tip area, and the fracture may propagate along the arms to the opposing ends of each arm.
  • the V shape of the rib in the lateral plane causes the tensile stress in the outer extent of the shell portion to be directed from a pure tensile force as predicted by beam theory, to components of force in the direction perpendicular to the plane of the rib and in a direction toward the flange or neutral axis.
  • This second component of stress causes the rib to flatten out (or try to align to the direction of the tension) and induce a local stress in the inner surface of the material which creates a local fracture.
  • the shell portion may preferably also include one or more inwardly directed elongate indentations provided adjacent one or both of the opposing ends of the rib.
  • the indentations may preferably extend from the flange of the body portion, and may generally extend parallel to the rib. These indentations act to reduce the stresses applied to the portion of the rib adjacent the indentations when there is an angular displacement of the first and second sections of the body relative to each other. The stresses may then be concentrated on the rest of the rib away from the opposing ends thereof. This facilitates the fracture commencing at and propagating from the fracture point at the tip area of the rib.
  • the opposing ends of the rib may be tapered to a tip adjacent the flange of the shell portion. Because the fracture propagation path is established at the tip area of the rib, it is not always necessary for the rib to extend completely to the flange of the container.
  • One of the body sections may be substantially longer in length than the other section.
  • the shorter section may be provided with a thumb or finger rest.
  • the container can be therefore opened by holding securely the longer section while displacing the shorter section of the body at an angle to the longer section by applying a pressing force on the thumb or finger rest.
  • the two sections of the container may be substantially identical in length. The container can then be opened by firmly gripping each body section with opposing hands and displacing both body sections towards each other by bending the container about the intermediate section.
  • a fracture along the periphery of the rib results in a lip that extends outwardly away from the middle of the resultant container opening. This outwardly extending lip does not form any obstruction for the resultant container opening therefore facilitating the free flow of the product stored within the container according to the present invention.

  • Figure 4 which is a detailed view of the area designated with the letter A from figure 3 shows in more detail the configuration of the rib 21.
  • the rib 21 extends along and at least substantially lateral plane 23 about the shell portion relative to an elongate access 25 of the body 3 (see figure 2).
  • the outwardly extending rib 21 is formed by two opposing wall sections 27, 29 which joined together at a joint area 31 forming a periphery of the rib 21.
  • the opposing wall sections 27, 29 define an included angle 33 (see figure 4). This included angle 33 can be equal to or between 0 and 180 degrees according to the present invention.

  • the second embodiment of a container 1 according to the present invention is substantially identical to the embodiment shown in figures 1 to 4 except for differences in the configuration of the rib 21.
  • the rib 21 in this embodiment also includes opposing wall surfaces 27, 29 which are joined at a join area 31.
  • a radius 35 is provided at the joint area 31 between the opposing walls 27, 29 so that there is a relatively smooth transition between the opposing walls 27, 29 at the join area 31.
