Definitions

  • the present invention relates to a container and a method and mould for making the container. It is envisaged that the container will be useful for containing objects which produce or give off liquid and/or moisture.
  • Food containers e.g. food trays for containing meat, typically comprise a base and one or more side walls projecting upwardly from the base.
  • these containers are usually provided with an absorbent pad, which is placed on the base, to absorb any liquid (e.g. blood or meat juices) from the meat.
  • absorbent pads add to the cost of the container, both in material costs and because the pad has to be added to the container during the packaging process. It would be desirable to find a way of retaining the meat juices, without using an absorbent pad.
  • one aspect of present invention proposes a container having a sidewall or sidewalls and a base having a plurality of apertures for retaining liquid by capillary action. As the liquid can be retained in the apertures by capillary action, the absorbent pad is no longer needed.
  • the invention will be particularly applicable to foodstuff containers, for example a meat tray for containing meat, but is not limited thereto; it may also find application to containers for cosmetics or containers for use in the medical industry, for example.
  • a first aspect of the present invention may provide a container having one or more sidewalls and a base having a plurality of apertures for retaining liquid by capillary action, each aperture having a depth at least 30% of its diameter.
  • the depth is at least 40% of the diameter, more preferably at least 50%. These greater depths, compared to the diameter, provide more effective capillary action. It is preferable that the depth is not greater than 60% of the aperture diameter. If the depth exceeds this level, then the manufacturing is made more difficult. For example, if a mould is used, then it is subjected to wear each time a moulded container is withdrawn from the mould. The deeper the apertures, the greater the friction on removing the formed container and the more rapid the wear. Furthermore, when the apertures are relatively deep compared to their diameter, e.g. a depth over 60% of their diameter, air might not be able to exit the apertures quickly enough if the entry of liquid is rapid or if the liquid is thick. Therefore it is best, although not essential that the depth is not greater than 60% of the aperture diameter.
  • each aperture has a depth of 30% to 60% of its diameter, more preferably 40% to 60%, in one embodiment the depth is 50% of the diameter.
  • Each aperture has an open end and a closed end, or bottom, usually opposite the open end.
  • the depth of the aperture is the distance from end to end and the diameter referred to above is the diameter of the open end.
  • each of the apertures will have approximately the same depth and cross-section, but this is not essential.
  • the apertures may have any appropriate cross-sectional shape, for example circular, hexagonal, square or rectangular.
  • the diameter for the purposes of the above ratio is taken to be the diameter of the biggest circle which will fit into the cross-sectional shape of the open end of the aperture.
  • the diameter of the apertures is 2mm to 6mm. This has been found effective for retaining liquids, especially meat juices. More preferably the diameter of the apertures is 2mm to 4mm; most preferably 3mm to 4mm, which has been found to work best for the retention of meat juices. In one embodiment the apertures have a diameter of 3mm.
  • the apertures may be concave, i.e. depressions in the base of the container. They may have a shape approximating a semi-sphere. However, for a given diameter at the open end, a semi-spherical shape will not maximise the volume of liquid which can be retained. Therefore, it is preferable for the apertures to have an approximately cylindrical shape. They may have substantially flat (non-curved) aperture side walls and a flat bottom (closed) end. However, this is difficult to achieve if the base is thermo formed.
  • the aperture sidewalls are straight portions extending at an angle within 10 degrees of the perpendicular with respect to the plane of the container base (they may be perpendicular).
  • the bottom (closed) end of the aperture has a flat portion.
  • this flat portion has a diameter at least 50% of the diameter of the open end, more preferably at least 60%. In this way the volume of the aperture can be larger than a semi-spherical aperture.
  • At a least portion of the aperture walls will usually curve inwards towards the flat portion of the bottom end of the aperture.
  • At least 50% of the base is covered with apertures for retaining liquid, more preferably at least 60%, most preferably at least 80%. It is best that as much of the base as practical has apertures, because in this way more liquid can be retained and the retaining will be less dependent on location on the base.
  • the base may have one or more ribs for supporting an object (e.g. meat) to be contained and/or for giving the base and/or container structural integrity.
  • an object e.g. meat
  • the base is formed of a non-absorbent material.
  • the container is integrally formed, preferably of a non-absorbent material.
  • the apertures are formed integrally in the base.
  • the closed ends of the apertures are integral with the base (e.g. the apertures each have a bottom wall at the closed end, integral with the aperture sidewalls.
  • the base is integral with the sidewalls. This simplifies the manufacturing process.
  • the container may be formed of plastic.
  • a hard plastic may be preferable, but an expanded plastic (e.g. expanded polystyrene) would also be possible.
  • the apertures are arranged in a hexagonal arrangement. That is a plurality of instances of a central aperture surrounded by six other adjacent apertures in a hexagonal arrangement; preferably the adjacent apertures are equidistant from the central aperture.
  • a second aspect of the present invention may provide a mould for a container, the mould being shaped to form a container having one or more sidewalls and a base, the mould having a plurality of features for forming apertures in the container base, said apertures having a depth at least 30% of their diameter.
  • the features of the mould for forming the apertures may be apertures in the mould or protrusions projecting from a surface of the mould.
  • a mouldable material moulds itself around said features to form the container base apertures.
  • the mould may comprise one or more sidewalls, and a base having a plurality of apertures having a depth at least 30% of their diameter.
  • the mould may be shaped for forming a container having any of the features described above under the first aspect of the present invention and so may have any of the features mentioned above under the first aspect of the present invention.
  • the mould may comprise more than one part.
  • a part of the mould for forming the apertures in the base of the container may be separate from a sidewall and/or base forming part of the mould.
  • the mould may have only a female part, or set of parts, or only a male part, or set of parts.
  • the mould may have both a male part or set of parts and a female part of set of parts (e.g. for forming upper and lower surfaces of the container).
  • the male part or set of parts or the female part or set of parts will have features for forming the apertures in the base of the container (said aperture forming features will be protrusions if in the male part of the mould, apertures if in the female part of the mould).
  • both the male and female parts may have features for forming the apertures in the base of the container.
  • the mould may be adapted for a thermoforming process.
  • the mould may be adapted for use in an injection moulding process.
  • the male part may have a plurality of protrusions for forming said apertures in the base of the container and be adapted to form said protrusions by compression of the container material.
  • the mould is formed of a material porous to air or the mould may have one or more through holes, e.g. small holes such as pinholes. Such through holes may be in the bottom end of mould apertures for forming the container base apertures.
  • Such through holes and/or the porous material are useful in certain moulding techniques as they enable a vacuum or suction to be applied beneath the mould in order to draw material to be moulded (e.g. a sheet of thermoplastic) onto or into the mould and helps the material to conform to the shape of the mould.
  • a third aspect of the present invention may provide a method of manufacturing a container, comprising forming a container base and one or more container sidewalls and forming a plurality of apertures in the base, the apertures having a depth of at least 30% of their diameter.
  • the method may have further steps for forming any of the features mentioned above under the first aspect of the present invention.
  • the apertures of the container may have any of the features mentioned above under the first aspect of the present invention.
  • the method may comprise placing or injecting a mouldable material onto or into a mould according to the second aspect of the present invention.
  • the mould may have any of the features mentioned above under the second aspect of the present invention.
  • the mouldable material may be heated.
  • the method may comprise allowing the mouldable material to harden after it has been placed into or onto the mould (e.g. the mouldable material may harden by cooling).
  • the mouldable material is plastic. It may be a thermo plastic. It may be an expanded plastic (e.g. expanded polystyrene) or a non-expanded plastic. It may be any of the container materials mentioned above under the first aspect of the present invention.
  • the method may comprise drawing or otherwise placing a heated sheet of (mouldable) material into or onto the mould, allowing it to assume the shape of the mould and then allowing it to harden (e.g. by cooling).
  • an injection moulding process may be used, whereby a fluid material (a liquid material, a melt or molten material, or semi-liquid material; e.g. a molten plastic) is injected into a two-part mould and allowed to harden (in the space existing between the two parts of the mould).
  • a fluid material a liquid material, a melt or molten material, or semi-liquid material; e.g. a molten plastic
  • two-part mould here is used in a general sense, it being understood that the mould may have more than two parts.
  • the container sidewalls and base may be formed in a first step (e.g. by thermoforming or another process) from a compressible material (e.g. an expanded plastic) and in a second step the apertures may be formed in the base of the container by mechanically deforming said compressible material.
  • a compressible material e.g. an expanded plastic
  • the compressible material will be allowed to harden before the second step is carried out.
  • the first step may be carried out with a female part or parts of the mould
  • the compressing step may be carried out with one or more male parts of the mould.
  • Vacuum, suction, air pressure, mechanical pressure, or a combination of any of these may be used to draw the mouldable material from which the container is to be formed into or onto the mould and/or to cause it to take the shape of the mould.
  • injection moulding fluid pressure is used for this purpose.
  • suction or vacuum are used then preferably at least a portion of the mould (e.g. its base) is formed of a material porous to air or the mould may have one or more through holes as described above under the second aspect of the present invention.
  • Fig. 1 shows a meat container for containing meat.
  • the present invention is however applicable, not just to meat but also to fish, other food stuffs and also non-food stuff containers for containing objects which give off liquid and/or moisture.
  • the container 1 comprises a base 5 and extending upwardly from said base, side walls 10.
  • the side walls form the perimeter of the container. In an alternative embodiment, if the container was circular, then there would in effect only be one side wall.
  • the container is in the form of a tray and has an outer rim 15, formed as a down turned flange of the side walls 10.
  • the side walls 10 have a plurality of strengthening ribs 20.
  • the base 5 has a plurality of strengthening ribs 25 extending laterally across the base of the container.
  • the base has a plurality of apertures 30 for retaining liquid produced by an object placed in the container (e.g. meat juices).
  • an object placed in the container e.g. meat juices.
  • a piece of meat When a piece of meat is placed in the container, it may rest on the raised (upwardly projecting) ridges 25 and blood and meat juices will drip and be deposited into the apertures 30.
  • Figs. 2 and 3 are side and end views of the container respectively.
  • Fig. 4 is a plan view showing an alternative container base, in this case for a rectangular container. It has a plurality of apertures 30 for retaining liquid. It also has sidewalls 10, with a flange 15, and ribs 20 as described for the Fig. 1 container.
  • Fig. 5 is a sideview of the Fig. 4 container.
  • Fig. 6 is a partial cross-sectional view showing some of the apertures along the line A-A of Fig. 1.
  • Each of the apertures has an open end 35 (which opens into the object bearing surface of the container base) and a closed end, or bottom, 50.
  • the apertures have the same size and depth as each other.
  • Each aperture has a depth x (from end to end of the aperture), which may be 30% to 60% of the aperture diameter D at the open end. In this embodiment the depth of the aperture is 50% of the diameter D. This ratio of depth to diameter has been found to provide effective retention of liquid by capillary action.
  • the apertures have a circular cross-section; it will also be possible to have apertures with a square, rectangular hexagonal or other cross-section.
  • the diameter for the purposes of the aforementioned ratio, should be taken to be the diameter of the largest circle which can fit in the aperture's cross-sectional shape at the open end.
  • Fig. 10 gives some examples of the diameter's, D, of apertures 30 with a non-circular cross-section.
  • the circles are imaginary circles used to determine the apertures diameters. It is thought that apertures with a diameter in the range 2mm to 6mm will be the best at retaining liquid. In this embodiment the apertures have a diameter of 3mm.
  • Fig. 6 is a cross-section showing the shape of the apertures in the present embodiment. It can be seen that the diameter, d of a flat section of the bottom of the aperture is more than 50% of the diameter D of the top, open end of the aperture.
  • the aperture side walls have a straight portion 70 which has an angle ⁇ of approximately 10° to the perpendicular (as measured from the plain of the container base).
  • FIG. 7 shows such an arrangement, in which a central aperture 100 is surrounded by six adjacent apertures 105, 110, 115, 120, 125 and 130 from a hexagonal arrangement. That is, a hexagon can be drawn by linking the centre points of each of the surrounding apertures.
  • the surrounding apertures 105, 110, 115, 120, 125 and 130 are equidistant to the central aperture 100.
  • the container is manufactured by a thermo-forming process.
  • a female mould 150 having an interior with the desired shape of the container is provided.
  • a heated sheet of thermo-plastic is then placed over the mould and allowed to take its shape.
  • the thermoplastic is then allowed to cool (or made to cool) so that it hardens and takes the form of the interior of the mould.
  • the thermoplastic sheet may be drawn onto the mould with the assistance of a vacuum, suction, air pressure (e.g. blowing air) or mechanical pressure, or a combination of them.
  • FIG. 8 is a partial cross-sectional view of a part of the mould 150, showing just a base portion thereof and three of the apertures 155 (which correspond to and have the same shape as the apertures 30 of the container described above).
  • the entire mould will have an interior with side walls, a base, ribs and so forth as shown in the container of Fig. 1 and as will be appreciated by a person skilled in the art.
  • the closed bottom end of the apertures 50 may have a hole 200 for allowing a vacuum or suction means to apply suction to the interior of the mould (and interior of the apertures 155).
  • the vacuum holes 200 may for example lead to a vacuum plate beneath the mould.
  • the mould may be made of a material porous to air, in which case the suction can pass through the mould and no, or fewer, holes 200 are needed. This is in fact preferable as manufacturing costs are then potentially decreased.
  • an injection moulding or even a mechanical pressing or punching process may be used.
