Definitions
- This invention relates to improvements in packaging.
- the invention is particularly applicable to the packaging of normally solid, or semi-solid materials that are capable of being rendered fluid by heating such as, for example, asphalt, paraffin wax or sulphur.
- material to be packaged is liquefied by heating and fed in a liquid state, to a container, preferably in the form of a sheath, formed of an appropriate packaging material, filling being performed whilst that portion of the sheath being filled is substantially surrounded, and cooled, by a liquid, generally water, contained, for example, in a tank, filled portions of the sheath being divided by appropriately sited apparatus which squeezes and cuts the sheath to form packages of filler material, the packages eventually Sinking in the liquid, preferably to conveyor or other lifting apparating which transfer them from the tank containing the water or other liquid to storage.
- the packaging material requires to be substantially impervious to the water or other cooling liquid in the tank and not to melt at the temperature at which the heated filling material is packaged.
- the packaging material is one that may be incorporated, in use, with the filler material, without detriment thereto, so that the complete package may be used without removal of its contents.
- Suitable materials are plastics such as polyethylene, polypropylene, polyvinyl chloride, polystyrene and cellophane.
- the material to be packaged, and the packaging material are so selected that the filler material seals, or helps to seal, the package thus obviating the necessity to employ expensive sealing equipment.
- the preferred packaging material is polyethylene.
- the liquid in the tank not only removes heat from the filler material but also serves as a supporting medium for the package thus permitting thinner films of packaging material than would otherwise be possible to be used without bursting under load.
- the cooling liquid preferably is selected to have a density intermediate that of the filler material in its liquid and solid states so that the packages float until their contents solidify and then sink in the cooling liquid, This ensures that, for much of the time that the package is cooling in the bath, the bursting stress on the packaging material is reduced.
- the containers are suitably formed by continuously assemblying sheeting, for example from rolls and forming the sheets firstly into a sheath.
- the sheath may be formed in various ways; for example, plastics may be fed from rolls and their edges welded together or a single sheet may be used and its two edges welded together.
- the sheet of plastics is unrolled and fed along the line of injection of the filler material being formed into a sheath before reaching the position of injection.
- plastics material may be formed into a sheath by direct extrusion blowing.
- the asphalt injection line can pass through the centre of the extrusion profile and injection can be performed at a distance from the extrusion outlet where the mechanical characteristics of the sheath are sufiicient for filling in the cooling liquid in the tank; it is still necessary, in this case, to provide for cooling of the sheath above the surface of the cooling liquid in the tank.
- the materials to be packaged are liquifiable or softenable, by heat and, when packaged, sink as they cool in the surrounding liquid to the carrying or transporting equipment.
- the invention is particularly applicable to the packaging of cold-setting liquids, such as asphalts, having mechancila characteristics that prevent handling and packing of the package at normal storage temperature Without considerable deformation. It is convenient to supply the materials by pumping, if possible, and thus, in general, the most suitable materials for packaging according to the method of the invention are those with a softening point above, say, about 50 C., and which are pumpable at higher temperatures, e.g. blown asphalt which may be pumped at about C. Any filling temperatures which will not cause melting of the container under the conditions of the filling method of the invention may be used but, in order to limit the cooling period in the tank, it is desirable to keep the temperature as low as possible.
- the method of the invention by filling and cooling in liquid, ensures that no mechanical forces are applied to the sheath during filling and setting of the filled material. Moreover, in certain cases, e.g. the packaging of asphalt, the packages remain afloat when first filled and sink when they are cooled. In this way the cooled packages become easily removable from the water tank.
- water has been specifically referred to as the cooling liquid, other cooling liquids may be employed, the cooling liquid preferably being selected to achieve floating of the packaged material until it becomes sufliciently cool to handle.
- a recirculation line 1 As shown in the drawing material to be packaged, e.g. heated blown asphalt, is recirculated through a recirculation line 1 and drawn off for packaging through a line 2 provided with a quick closing valve 3.
- Rolls 4, of sheathing material 5, e.g. polyethylene, are unrolled in the path of line 2 and joined e.g. by high frequency electrical equipment, at 6.
- Material from line 2 fills into the sheath formed by joining the sheet 5, and passes downwards to a tank 7 containing liquid, e.g. water 8.
- the filled sheaths 9 are closed and separated as shown at 10' by appropriate squeezing and cutting means and, preferably, float as shown at 9a, until they cool and sink, as shown at 9b, to a belt conveyor lifting system 11 which transfers them from the tank 7 to storage.
- a water spray 12 suitably of circular form, which enables a cooled material level to be provided inside the sheath a small distance above the water level and also to provide a static material 8 (e.g. asphalt) pressure counteracting the hydraulic liquid pressure in the tank.
- An air supply as shown at 13 is also suitably provided.
- the bagging method of the invention permits the employment of packaging material that is compatible with the material to be packaged.
- the liquid in which the materials are packaged and the means provided above the surface of this liquid act also as a cooling medium which protects the packaging material from melting even if the filling temperature of the material being filled is substantially in excess of the melting point of the packaging material; thus, when packaging asphalt into polyethylene sheathing filling temperatures as high as 210 C. may be employed without detriment to polyethylene sheaths of melting point, in air, of
- the method of packaging normally solid or semisolid material which comprises liquefying the said material by heating and feeding it in a liquid state to a container, filling being performed whilst that portion of the container being filled is substantially surrounded, supported and cooled, by a liquid, cooling means also being applied to the container at a position above the surface of the said liquid.
- sheath is formed from polyethylene, polypropylene, polyamyl chloride, polystyrene or cellophane.
- Apparatus for packaging normally solid or semisolid material comprising means for delivering sheet material, means for forming said sheet material into a sheath, means for delivering liquefied filling material to said sheath, means for delivering said sheath whilst being filled to a bath adapted to contain liquid, means to cool a portion of said sheath above liquid in the bath and means in said bath for squeezing and cutting portions of said sheath to form packages of filler material.
