  • FIG. 2 shows a slightly enlarged section view, taken according to line II-II of Figure 1 , relating to the preferred embodiment of the present invention, in a condition wherein the filling operation has been completed;
  • FIG. 3 shows a front elevation view of the present invention, highlighting in particular the filling phase effected with the product in liquid condition.
  • Figures 1 through 3 show a preferred embodiment of the package of the present invention.
  • the package is for a food product which, fed into the container in substantially liquid condition is made to solidify to be consumed in the form of a solid product.
  • the present package embodiment of the invention is preferably used for packaging a cheese, which is fed in the molten state into the container of the package. It is nonetheless usable for any other kind of food product such as ice cream, chocolate, jam or other products which can be fed in liquid condition into the package and can subsequently solidify in view of their use.
  • any other kind of food product such as ice cream, chocolate, jam or other products which can be fed in liquid condition into the package and can subsequently solidify in view of their use.
  • the package 10 comprises in essentially known manner a container 12 defining an inner chamber 14 and a food product 16 housed in said inner chamber 14 of said container.
  • the container 12 comprises a first and second associated shells 18, 20 facing each other to realise said inner chamber 14 for housing the food product.
  • Said shells 18, 20 are mutually joined by seal 19 obtained between the respective peripheral borders 21, 23 of mutual contact which contour, delimiting it at the centre, said housing chamber 14.
  • the material with which said shells of the container are realised is a plastic material having at least its inner surface, destined to contact the product, which can be peeled to allow for an easy detachment of the container from the product upon consumption thereof.
  • the present embodiment of the package comprises means suitable to allow mutually to disengage and separate said first and second shell 18, 20 realising the container 12.
  • said means for disengaging and separating said first and second shells 18, 20 comprise, on each of said shells of the container, respective first 32, 34 and second 36, 38 portions for gripping and spreading said shells 18, 20, which are positioned mutually opposite and close, though detached.
  • the present embodiment advantageously provides suitable means for confining the air bubble, indicated in the figure with the numeric reference 40, in a pre-defined position within the package 10.
  • said means to confine said air bubble 40 in a pre-defined position within the package 10 comprise, on the package, means for receiving or containing said air bubble 40, and means for retaining said air bubble within said receiving means. In this way the air bubble is prevented from circulating within the package before the solidification of the product, causing the drawbacks related above.
  • said means for receiving said air bubble 40 are in the form of an elongated cavity 29, opening into the product housing chamber 16, which in the present embodiment is provided by a hollow tubular element 24 whose inner longitudinal cavity defines said cavity 29 for receiving said air bubble.
  • said hollow tubular element 24 extends for a certain section, with its lower longitudinal portion 28, into the product housing chamber 14 of said container 12 and presents means suitable to allow the insertion of the air bubble 40 into the cavity 29 of the tubular element.
  • Said insertion means in this specific instance are realised by holes 42, 44, provided in the peripheral wall 46 of the tubular element 24.
  • said passage holes 42, 44 are advantageously provided in the portion of tubular element 24 that is, inside the product housing chamber 14, in the vicinity of the upper wall 43 of the container 12.
  • said tubular element 24 is, preferably, in the form of an element that is separate and distinct from said container 12 and is associated, with hermetic weld, to the container 12 itself in correspondence with a through opening 22 of the container which opens inferiorly into the chamber 14 for housing the product and superiorly towards the exterior of the product.
  • the weld joining the tubular and the container being obtained by heating the plastic material of the container.
  • the tubular element 24 extends upwards and also realises, through its inner cavity 29, open at both ends, means for the introduction of the product in liquid condition into the chamber 14 of the package.
  • the liquid filling material is inserted into the tubular element 24 through the open top end 241 , and is transferred to the inner chamber 14 of the package through the open lower end 242 of the tubular element.
  • Means for closing the inner cavity 29 of said tubular element 26 are provided, in the form of a hermetic weld 30 (shown in Figures 2 and 3) between opposite edges of the tubular element 24, realised upon completion of the package filling operation, in correspondence with the free top end 26 of the tubular element 24.
  • a preferred method for obtaining the present package thus provides for starting from a container 12 of the package which presents, as stated previously, an inner chamber 14 and a through opening 22 which opens into said inner chamber
  • the method then provides for introducing or injecting, into the inner chamber 14 of the container 12, the food product 16 in substantially liquid condition through an appropriate feeding nozzle 25, as shown in Figure 3.
  • said container is provided, as referred above, with means 29, or equivalent, suitable to receive, by insertion thereinto, said air bubble 40 with the additional provision of means suitable for retaining said air bubble 40 within said receiving means 29.
  • the insertion and trapping of the air bubble 40 within said receiving means 29 occurs automatically in the course of the filling operation of the product in liquid condition in the package.
  • the filling of the package preferably occurs with the package 10 held vertical in such a way that said means 29 for receiving said air bubble are placed in a position above said product housing chamber 14 of said container and injecting from above the product (indicated by the arrows P directed downwards in Figure 3) in liquid condition.
  • the product in liquid condition is made to pass through said cavity 29 of the tubular element 24, accumulates starting from the bottom of the housing chamber 14 and rising therein it progressively ejects the air contained within said chamber 14.
  • the elimination of said air from the package occurs through said lateral holes 42, 44 provided in the tubular element, which allow the passage within the inner cavity 29 of said tubular element and the escape therefrom, flowing opposite to the feeding of the filling product.
  • the sealing closure of the package is effected by means of a welding 30 of the tubular element 24, which as Figure 2 shows is obtained in correspondence with said upper end of the tubular element, where said bubble 40 is positioned, remaining trapped below said weld 30.
  • tubular element 24 extends superiorly beyond the container 12, it is possible to obtain, in addition to the easy introduction into its inner cavity 29 of said air bubble 40 by positioning the bubble itself in an area far from the product to be consumed, also an extremely easy and rapid execution of said sealing weld 30 of the package, which is effected by the simple adhesion of opposite walls of said tubular element and presents a high degree of reliability.
  • the means to retain or trap the air bubble within said tubular receiving element are determined by the ratio between the length, or depth, of the receiving cavity 29 and the inner diameter, or transverse dimension, thereof; said length/diameter ratio of the cavity 29 is determined in such a way as to prevent said air bubble from escaping outside the receiving cavity under any operative situation experienced by the package during the subsequent handling operations. In this way it is possible to prevent said air bubble, once trapped, from departing, as an effect of any movement, even if the package is upset, said tubular cavity 29 and return to the chamber 14 housing the food material 16.
  • a 2 to 1 ratio between the length of the tubular element and the inner diameter of the cavity of the tubular element, and higher ratios, can be particularly well suited to the attainment of the aforesaid purpose.
  • said means to retain the air bubble 40 within said receiving cavity 29 to be determined by such a ratio between the length of the receiving cavity 29 and its diameter as to provide a capillarity effect on the liquid product within the cavity 29 for receiving the air bubble. This capillarity effect keeps the column of liquid present below the bubble 40 firmly within the cavity 29 and prevents any possible leakage of the air itself from said cavity 29.
  • the capillarity effect inside the cavity 29 of the tubular element further provides, in the final phases of the filling operation, when the nozzle 25 no longer dispenses said material and just before the intervention by the welding plates that provide for the welding 30 of the top of the tubular element 26, a certain rise of the liquid product inside the cavity 29 which allows to eject, before the closure welding, a greater volume of air and hence determines, within the package, an air bubble with a more reduced volume.
  • the presence of an elongated tubular element that extends within the container and externally therefrom, possibly also only inside and outside it, also allows to introduce the material in liquid condition with less turbulence into the inner chamber of the container thereby obtaining a reduction in the formation of bubbles or air inclusions within the product.
