Definitions

• the present invention relates to a support plate for a package suitable for containing a food product.
• the present invention also relates to a system comprising the support plate and a filling machine comprising the system.
• Tetra Top ® package has a top portion with a closure (such as a screw cap) surrounded by convex or straight surfaces extending out and down towards four vertical side walls. During a filling operation this type of package is held with the closure facing downwards before the package is filled with a food product from above and through the opposing end of the package i.e. the end that eventually forms the bottom of the package as understood by the consumer. The bottom portion is then sealed and the filled package is removed from the filling operation.
• a closure such as a screw cap
• More recent packages include a concave surface on their top portion and a concave surface elsewhere on the package such as at an edge between two of the adjacent vertical walls.
• a concave surface and a concave edge have an aesthetically pleasing appearance and may function as a thumb grip for the user when the food product is poured from the package.
• packages with a concave surface on their top portion and a concave edge tend to rotate or twist during filling operations. This leads to incomplete package filling and stoppages in filling operations.
• WO 2015/086362 discloses a package carrier for a tetrahedral-shaped package.
• package carrier is unsuitable for use with packages having a top portion with a concave surface.
• the WO 2015/086362 package carrier is also unsuitable for use with packages having a concave surface at another location of the package such as an edge between adjacent side walls.
• a support plate for supporting a package during filling with a food product, the support plate comprising: a wall defining a cavity for receiving a top portion of the package;
• the wall having a slanted interior surface that is complementary to the top portion of the package
• a support projection extending in a parallel direction to and away from the wall, the support projection being complementary to and for abutting the top portion comprising a concave top surface and a concave surface of the package.
• a system for use in a filling machine comprising:
• a support plate for supporting a package during filling with a food product
• the support plate is mounted on the package guide and the package guide is configured for receiving the package.
• a filling station for filling a package with a food product when the package is being supported by the support plate of each system.

• Figs. 1 A and 1 B illustrate support plates 100 and 1 50 respectively that are suitable for use with the package depicted in Figs. 3A and 3B that will be described below.
• Support plates 100 and 150 each comprise a wall 104, 154 surrounding a cavity 1 12, 1 62. Walls 104 and 154 have a slanted interior surface 108, 158 which is best shown in Fig. 2 in respect of support plate 150.
• a support projection 1 1 6, 1 66 extends vertically upwards to and from walls 104 and 154.
• Clip members 120, 170 are located at opposing ends of an
• Each clip 120, 170 has a clip recess 174 as depicted in Fig. 2.
• a grip member 132, 182 is located on a longitudinal side of the connecting portion 128, 178.
• the grip member 132, 182 is configured for engaging with an automated arm (not shown) of a filling machine in order to move the support plate to a different height or location as necessary.
• the support plates 100, 150 are injection moulded from plastic such as polyoxymethylene (POM) or polyoxyethylene.
• the plastic is resistant to hydrogen peroxide solutions and / or UV light as used during sterilisation of the packages in a filling machine or process.
• support projections 1 1 6 and 166 on walls 104 and 154 is the sole difference between support plates 100 and 150. Both plates 100 and 150 may be used in a filling machine depending on the location of the plate in the filling machine and the orientation of the package to be used with the plate 100, 150. Although the support projections 1 16 and 166 are illustrated in one corner of walls 104 and 154, they need not be located in the wall corner. For example, the support projections 1 1 6 and 166 could be located on the side of the walls 104 and 154 i.e. between two adjacent corners of the walls 104 and 154.
• the slanted interior surfaces 108, 158 and the cavities 1 12, 1 62 are configured for receiving the top dome of a package.
• the shape of the support projections 1 1 6, 1 66 is complementary to a concave top surface and another concave surface (such as a concave edge) of a package in order that the projections 1 1 6, 1 66 are able to abut and support the concave top surface and the concave surface (e.g. concave edge). This will become clearer with respect to Fig. 4 below.
• Figs. 3A and 3B illustrate a package 200 suitable for use with the support plates 100 and 150 in Figs. 1 A and 1 B.
• Package 200 has four lateral walls 204 and a concave surface 208 at an edge between two adjacent lateral walls 204.
• the top dome of package 200 comprises a convex top wall 212 and a concave top surface 216.
• a sealing ring 224 joins the top dome to the lateral walls 204 and the concave surface 208.
• a closure 220 atop the dome seals the package 200.
• the closure 220 may be a re-sealable screw cap or a peel-back lid.
• Fig. 4 illustrates a system 320 for use in a food product filling machine.
• System 320 comprises a package guide 300 and a support plate 150 as described in Fig. 1 B mounted on the package guide 300.
• support plate 100 may be used instead of support plate 150 in system 320.
• the package guide 300 is configured for mounting to a rotating support (not shown) inside a filling machine.
• Guide 300 is overall tubular in shape for receiving a package 200 as depicted with dashed lines.
• the package 200 enters guide 300 at bevelled end 312 and is lowered through guide 300 until the convex top wall 212 and the concave top surface 21 6 of the package's top dome rests on the complementary slanted interior surface 108, 158 of wall 104, 154.
• the concave surface 208 of package 200 also rests against the support projection 1 1 6, 1 66 of support plate 100, 150.
• Package guide 300 has a plurality of support ridges 304 located on external opposing faces of guide 300.
• the support ridges 304 are arranged in pairs wherein each member of a given pair is located at the same height on the guide 300. In this way a pair of ridges 304 is receivable by clip recesses 174 of clip members 120, 170.
• This allows adjustment of the support plate 100, 150 to a different height on the guide 300 depending on the volume of the package 200 that is to be filled.
• the height of the support plate 100, 150 may be adjusted by cooperation between grip member 132, 182 and an automated arm (not shown).
• a viewing hole 308 is also provided on package guide 300 for facilitating inspection of decor or other features of the package 200.
• the package guide 300 is preferably made of metal.
• Figs. 5A and 5B illustrate a filling machine 400 comprising a plurality of systems 320 mounted to a rotating support 404 that rotates in the direction of the arrows.
• Filling machine 400 also comprises a sterilizer 408 such as an ultraviolet lamp, a HEPA (high efficiency particulate air) purifier, and / or a hydrogen peroxide sprayer.
• the filling machine 400 may also comprise a package feeder for providing a package to the systems 320, a filling station for filling the package with a food product, and a sealing station for sealing the bottom of the package after filling.
• Fig 5B depicts that one side of the filling machine may comprise systems 320 with support plates 100 while the opposing side may comprise systems 320 with support plates 150.
• This arrangement of supporting plates is suitable for use with a package feeder configured for providing packages 200 in one orientation only to all of the systems 320 in the filling machine 400. All concave surfaces 208 of packages 200 will be correctly orientated with support projections 1 16 and 1 66. Sterilizer 408 is omitted from Fig. 5B for clarity.
• the support plates 100, 150 also absorb additional pressure generated on the package 200 during filling without damaging the package 200.
• the support provided by projections 1 1 6 and 1 66 also allows for reducing or eliminating the requirement for a sealing ring 224 thereby improving the visual appearance of the package 200.
