Definitions

  • the present invention relates to a container capable of forming predetermined shapes of materials enclosed therein and refers particularly, though not exclusively, to a preformed receptacle for receiving fluids to he solidified into the predetermined shape.
  • the invention also provides a method and apparatus for forming the container.
  • the invention finds particular application in the preparation of shaped articles e.g. ice, gelled preparations, liquids and other solid or semi-solid materials.
  • a conventional method for making shapes of ice in a domestic situation is that a tray is used which has therein a number of indentations of a particular shape. Water is placed in the tray so that it fills the indentations and the tray is then placed in the freezing compartment of a refrigerator so that the water freezes into shapes as defined by the indentations.
  • the tray is sometimes made of a plastics material in which case it is preformed into the desired shapes, or is sometimes made out of metal and an insert is provided to define the required shapes.
  • the main problem here is the removal of the ice. Also, once the ice is formed it must be forcibly ejected from the tray whereupon the tray is ready for re-use.
  • a further object of the invention is to provide a container which is cheap and allows individual selection of an ice shape without disturbance to adjacent ice shapes.
  • the invention in one aspect provides a container of laminated formation wherein at least one layer is so formed as to provide, in conjunction with the other layer(s) a cell-like structure whereof the cells are of, or are expandible into, predetermined shape(s) and wherein the cells are joined to adjacent cells by means of passages; an inlet being provided to at least one of the cells to enable fluid to be received by the cells; and at least one air outlet passage for allowing escape of displaced air.
  • a method of forming containers including the steps of: heating a thermoplastic. sheet material, guiding said heated material over a roller having linked cellular depressions therein, reducing the air pressure within said covered depressions to vacuum form the cell-like structure and bonding at least one further layer of sheet material to said formed layer to produce said container.
  • Figure 1 is a schematic illustration of the machine
  • Figure 2 is a front elevation of a portion of the face of the bubble forming roller
  • Figure 3 is a section on line AA of Figure 2, showing two interlinked sockets
  • Figure 4 is a section on line BB of Figure 2;
  • Figure 5 is a front elevation of a finished container;
  • Figure 6 is an end elevation of the container; and Figure 7 is a side elevation of the same container.
  • the invention will be described with reference to a container for shaped ice.
  • FIG. 5 shows a container 2 of substantially rectangular configuration which comprises two thin sheets of plastics material 4 and 6 super-imposed to form a laminated structure.
  • the first layer 4 is so preformed as to be capable of defining, with the second layer 6, the desired arrangement of cells 8 which are designed to receive water and which, once frozen, form bodies of ice corresponding in shape to the expanded cells.
  • the lastmentioned preferably have a domed cylindrical shape as best seen in Figures 6 and 7.
  • Each cell 8 is joined to the adjacent cell or cells by means of passages 10. when the container 2 is held in a vertical position the water preferably passes from the bottom of one cell to the top of an adjacent cell so that, when water is being placed into the container, it will fill from the bottom and will tend to force air from the top of the lower cells to the cells above. In this way all of the air can be expelled from the cells.
  • a water inlet opening or funnel-portion 12 also as a preformed cell in the first layer 4 which enables water to be passed into the top-most cell 14 to enable air to be expelled from the container 2 via the passages 10.
  • the topmost cell 14 is also provided with two air outlet passages 16 and 18, one on either side of the inlet funnel 12.
  • the laminated cellular or potentially cellular structure is preferably made by appropriately forming the first sheet 4 on a machine, and then superposing the other layer 6 to form the desired structure.
  • the cells may be formed by a blow-moulding technique or by a machine to be described later.
  • the container is provided with weakened portions 20 and 22 in the form of perforations, tearing along which provides two upper ears 24 and 26.
  • the perforations 20 and 22 may be torn and the two ears 24 and 26 tied to seal the water inlet 12 and the air outlets 16 and 18 so that the water contained in the cells 8 and the passages 10 will not be allowed to escape whilst the water is freezing. This will also prevent spillage when the ice melts if it is being used to cool bottled beverages.
  • a problem with the formation of ice is that water expands as it freezes.
  • the cellular layer 4 need not be adhered to a plastics layer 6 but may be bonded to other materials e.g. paper, foil, etc.
  • FIG. 1 to 4 there is shown a machine for forming the container 2.
  • a first sheet of plastics material 28 is fed from a supply roll (not shown), and round a tensioning roller 30 onto a main drum or roller 32, having a series of depressions or sockets 34 formed in the face thereof to form the cells in the material 28.
  • the shape and arrangement of these sockets 34 will coincide with the desired cellular pattern on the finished containers, e.g. the container 2 shown in Figure 5.
  • a hexagonal arrangement of sockets has been found to be suitable.
  • This hexagonal arrangement of sockets 34 enables the sockets to be connected together by passageways 36, also in hexagonal arrangement.
  • the passageways 36 are slots or grooves formed in the walls 38, between the sockets 34.
  • Each socket 34 has an aperture 40 in the base thereof, covered by a suitable perforate cover or mesh 42 to prevent the plastics sheet 28 from being sucked down into the aperture 40.
  • These apertures 40 are connected to a suitable suction source associated with the main roller 32. As the plastics film 28 passes around the roller 32, it is heated by a suitable heat source, e.g. a radiant heater 44.
  • the film 28 is heated until it softens and sags partly into the socket 34 and into the channels 36, to thus seal the periphery of each socket, enabling the suction through the aperture 40 to suck the film down into the socket.
  • a second film 46 is passed over a tension roller 48 and around a pressure drum 50. This film 46 is heated by a radiant heater 52 and the heated films 28 and 46 passed through the nip between the rollers 32 and 50, to heat-weld the two films together. This results in the formation of both the cells 8 and the passages 10 therebetween, and series of containers can be formed side by side depending upon the ultimate size of the roller.
  • film 28 is thicker than film 46 to allow for the thinning of film 28 when vacuum formed.
  • roller 32 will also be provided with indentations corresponding to the water inlet funnel 12 at the top of the container.
