Definitions

  • the present invention relates to a plastic bottle particularly for containing beverages.
  • a shift has occurred from the conventional bottle with a capacity of 0.75-1 liter to bottles with a capacity of 1.5-2 liters, with a current tendency to produce 5- and 6-liter bottles.
  • the conventional bottle shapes currently in use have circular or square cross-sections.
  • Bottles having a circular cross-section have excellent resistance to internal pressure without deforming their walls.
  • bottles that have a circular cross-section suffer the drawback that they do not use completely the space, and therefore the capacity, that is available in storage and subsequent palletizing.
  • Bottles that have a square cross-section instead fully utilize the space, and therefore the capacity, that is available in storage and palletizing, and can also benefit from a lateral support that is very stable because it is formed by a surface.
  • bottles full of liquid are usually stacked one on top of the other; to do this, the bottles must be rigid enough to avoid crushing and collapsing of the lower bottles caused by the upper ones.
  • inert gas is added in the internal free space; this produces a higher internal pressure, which tensions the walls of the bottle.
  • bottles that combine square and circular body features are known from documents FR-1353643 and FR-2576283 .
  • the aim of the present invention is to provide a plastic bottle, particularly for containing beverages, whose resistance to stresses is comparable to that of bottles having a circular cross-section and whose capacity, palletizing and storage possibilities are comparable with those of bottles having a square cross-section.
  • an object of the present invention is to provide a plastic bottle that improves capacity and storage strength.
  • Another object of the present invention is to provide a plastic bottle that is more stable during handling.
  • Another object of the present invention is to provide a plastic bottle that withstands higher internal pressures than square-section bottles of equal volume.
  • Another object of the present invention is to provide a plastic bottle whose production costs are in any case competitive with respect to the costs of bottles of similar capacity.
  • Another object of the present invention is to provide a plastic bottle that can be manufactured with known equipment and technologies.
  • a bottle according to the invention is generally designated by the reference numeral 10.
  • the bottle 10 comprises a body in which portions that have a circular cross-section are alternated with portions that have a substantially quadrangular cross-section.
  • the body of said bottle is cylindrical and is designated by the reference numeral 11; the bottle 10 further comprises a shaped bottom 12 and a neck 13 with a threaded end for a cap.
  • the bottle 10 is made of plastics by means of conventional blow-molding techniques, particularly with the material usually known by the acronym PET.
  • the bottle 10 has domed portions 14 that protrude on the upper part and on the lower part of the body 11, separated by a waist portion 19.
  • the domed portions 14 respectively form, on the upper part and on the lower part of the body 11, two contoured bands 16 that have a substantially rectangular cross-section.
  • the domed portions 14 substantially have a semicircular profile that is eccentric with respect to the axis of the cylindrical body 11.
  • the surfaces of the domed portions 14 encounter the surface of the cylindrical body 11 with such an angle as to form discontinuities 17.
  • the base portion 15 of the surface of the body 11 that lies between two contiguous domed portions 14 that belong to the longer side of a same band 16 is tangent to a straight line that is tangent to the surfaces of the two contiguous domed portions 14; said bottle can therefore be laid to rest with its longer side against a surface on three contact segments or regions of two adjacent domed portions 14 and of a base portion 15.
  • the bottle 11 is formed by blow-molding, as mentioned, the amount of material that is deposited in every part of the mold is the same, and therefore, since the diameter of the cylindrical body 11 is smaller than the width of the domed portions 14, said cylindrical body is thicker than the domed portions 14.
  • the cylindrical body 11, particularly at the cylindrical narrower portions 18, 19, is therefore stronger than the domed portions and less subject to stretching.
  • the present invention provides a plastic bottle whose resistance to stresses is comparable to that of cylindrical bottles, said bottle further having a capacity, and offering palletizing and storage possibilities, comparable to those of bottles having a square cross-section.
  • the present invention provides a plastic bottle having a predominantly square cross-section that is capable of withstanding internal pressure without undergoing deformation, differently from current square-section bottles, which undergo deformation with a minimal increase of the internal pressure with respect to the atmospheric pressure.
  • the present invention provides a plastic bottle that is more stable during handling than cylindrical bottles.
  • the present invention provides a plastic bottle that allows to reduce average wall thickness for an equal volume, reducing the amount of material used and making its production costs in any case competitive with respect to the costs of bottles of similar capacity.
  • the materials employed may be any according to requirements and to the state of the art.
