Definitions

  • the invention relates to the plastic bottles used for storing liquid materials.
  • the invention especially relates to an embodiment that allows both increasing the strength of the bottle and using less plastic raw material by applying column structure in the cross section of the plastic bottle.
  • plastic bottles are widely used for storing and transporting liquid materials under hygienic conditions. Especially, due to the fact that plastic raw materials cost lower than raw materials such as glass or metal, the use of plastic bottles becomes widespread day by day.
  • the European Patent Application No. EP2321 113B1 relates to "Equipment for shaping bottles with shaping means and corresponding method".
  • This invention is related to an equipment that shapes bottles by thermoforming a plastic sheet and said equipment comprises a blowing and/or filling tube, a sealing means and molding means for said bottles.
  • the invention comprises means for shaping said sheet into a cylinder; said shaping means are positioned upstream from said molding means and said equipment has first and second jaws arranged around said tube; the inner contours of said tube define a cylinder; the second jaw has a slot extending longitudinally on at least one portion of the tube length and opposite of which sealing means extend; here stopping means define an abutment for at least one of the free edges of said sheet, said abutment extends essentially in the axis of said slot .
  • any embodiment regarding the formation of column structure on plastic bottle cross section is not mentioned.
  • EP1705124B1 is related to a bottle made of plastic material, with a reinforced bottom produced using the technique of blowing an extruded or coextruded parison of high-density polyethylene (HDPE) or other suitable material and particularly suitable for the sterile packaging of liquids for foodstuff use or for other uses for which sterile packaging conditions are required, for example for packaging liquids for cosmetic, pharmaceutical or similar uses.
  • HDPE high-density polyethylene
  • a column embodiment performed on the body cross section of the plastic bottle is also not mentioned.
  • the main object of the invention is to develop a method that allows both increasing the strength of the bottle and using less plastic raw material by applying column structure in the cross section of said plastic bottle to remove current disadvantages.
  • a method with a plastic bottle production system for producing plastic bottles used for storing liquid materials comprising a feeding chamber in which the plastic raw material that forms the bottle is placed, a main extruder that is the section where the raw material that forms the main structure of the plastic bottle is mixed and heated, and a head where plastic raw material is shaped into a cylinder;
  • an additional head with at least one raw material flow line is positioned on the head to which the main extruder is connected,

  • the invention relates to a method that allows both increasing the strength of the bottle and using less plastic raw material by applying vertical column structure (6) at certain intervals in the cross section of the plastic bottle body (7).
  • Plastic bottle production systems (A) are utilized for plastic bottle production.
  • Plastic bottle production systems (A) comprise a feeding chamber (1) in which the plastic raw material that forms the bottle is placed, a main extruder (2) that is the section where the raw material that forms the main structure of the piastic bottle is mixed and heated, and a head (3) where plastic raw material is shaped into a cylinder.
  • plastic bottle production system (A) comprises an additional head (4) which comprises raw material flow line (4.1) from four sides for feeding the raw material to the head (3), i.e. main cylindrical structure from four sides, and which allows formation of vertical column structure (6) on plastic bottle body (7) with certain intervals.
  • An additional extruder (5) connected to additional head (4) for mixing and heating the raw material that forms vertical column structures (6) providing strength of plastic bottle body is used.
  • Wall thickness of the plastic bottle body (7) according to the invention is decreased, instead, bottle made of plastic or its derivations supported by at least one column structure (6) in order to provide vertical strength is created.
  • raw material is placed in feeding chamber (1).
  • Raw material, being mixed by the main extruder (2) on one hand is subjected to heating process on the other. Afterwards, flowing in the shape of a cylindrical pipe, it comes out of the head (3).

  • the final product is a bottle with lower wall thickness, while the lack of strength due to this thinness is solved by the column structure (6) according to the invention.
  • the column structures (6) formed on the plastic bottle body are preferably four in number, wherein they extend vertically along the plastic bottle body (7).
  • Plastic raw materia! composing column structure (6) is different than the raw material that forms the plastic bottle body (7) and is more rigid with regard to this raw material.
  • the plastic bottle body wall thickness (d2) is smaller than the column wall thickness (d1).

Abstract

L'invention concerne un procédé qui permet à la fois d'augmenter la résistance d'une bouteille et d'utiliser moins de matière première plastique par le biais de l'utilisation d'une structure de colonne verticale (6) à certains intervalles dans la section transversale du corps de la bouteille en plastique (7).
