Definitions

  • the invention relates to a closure system and a closure method for a container.
  • PET aerosol containers are usually closed with a crimped on metal cap in which the PET material of the container folds over a portion of the metal cap and then crimped together to form a seal.
  • a closure system for a plastics container said container having a neck portion leading to an opening, the system including:
  • a cap having: o a deformable shoulder zone configured to abut against an inner surface of the neck portion of the container; o a lip portion configured to, in use, overlap an external surface of the neck portion of the container; and
  • the cap may be made of metal.
  • the restraining means may be a stiff ring sized and dimensioned to fit snuggly onto the outer surface of the neck portion of the container.
  • the restraining means may be a high tensile plastics material, for example a glass filled nylon ring, or a metal ring.
  • the restraining means may be integral with the neck portion.
  • the restraining means may be a stiff portion of the neck portion.
  • the restraining means may be made of the same plastics material as the neck portion.
  • An aperture may be provided in the cap for a fluid flow tube which, in use, allows fluid to flow from the interior of the then sealed container to the exterior for use.
  • a seal ring may be provided which is interposed between an upper edge of the neck portion and the cap to improve sealing.
  • a wick may be provided in the cap and a wick protector for covering the wick.
  • a method of sealing a plastics container having a neck portion leading to an opening by the co-operation of a cap member having a shoulder zone and a restraining means said method including:
  • the method may include deforming a neck portion outer surface facing portion of the cap member towards the neck portion thereby to reinforce the seal.
  • the outer surface facing portion may overlap a portion of the neck portion.
  • the deformation of the outer surface facing portion may include crimping of the cap.
  • the plastics container of the invention may be a PET aerosol container.
  • the plasties container may be a polycarbonate container.
  • the plasties container may be pressurisable.
  • the plasties container may be used to package paraffin with LPG gas for use in paraffin stoves.
  • Reference numeral 10 generally indicates a PET aerosol container broadly in accordance with the invention.
  • the container may be made of polycarbonate which, although presently more costly than PET, has a higher temperature resistance, a higher physical strength and good transparency.
  • the container 10 has a neck portion 12 which is the same wall thickness as the rest of the container and has an inner surface 14, an outer surface 16 and an opening 18.
  • a cap 20 is provided which has an internal recess 22 which is defined by a shoulder zone 24 which has an internal recess facing surface 26 and a neck portion 12 facing surface 28.
  • a further zone 27 of the cap 20 is located to the exterior of the cap and forms a sleeve 29 which, in use, overlaps the neck portion 12 outer surface 16.
  • the cap 20 is made of deformable steel.
  • a ring 30, of steel in this example is provided.
  • the ring may be made of a glass filled nylon or other plastics material in which case the ring dimensions would be different in that the depth of the ring which is 2.1 mm for a steel ring would be 3.0 mm.
  • a seal 40 is made of resiliently deformable material.
  • the ring 30 is placed over the outer surface 16 of the neck portion 12 and fits quite snugly thereover.
  • the seal 40 is interposed between the cap 20 and the neck portion 12.
  • the cap 20 is then placed onto the opening 18 of the container 10 with the recess 22 being placed into the opening 18 so that the surface 28 of the shoulder zone 24 overlaps and faces a portion of the inner surface 14.
  • the cap 20 is then deformed by application of a force to surface 26 thereby increasing the diameter of the surface 28.
  • the extent of the deformation and thus, diameter increase is limited by the snug fitting ring 30.
  • the cap 20 seals against the neck portion 12.
  • the outer zone 27 can then be crimped onto to the ring 30 to reinforce the seal.
  • a wick protector 50 is placed over a wick 52 attached to lid 20.
  • the wick protector 52 is removed prior to the wick being set aflame.
  • the inventor believes it to be an advantage of the invention as illustrated that the assembly of such an aerosol is simplified thereby reducing manufacturing costs thereof.

Abstract

L'invention concerne un conteneur aérosol (10) pourvue d'une partie col (12) dont l'épaisseur de paroi est la même que celle du reste du conteneur et possède une surface intérieure (14), une surface extérieure (16) et une ouverture (18). Un capuchon (20) possède un retrait interne (22) qui est défini par une zone d'épaulement (24) qui possède une zone opposée au retrait interne (26) et une surface opposée (28) à la partie col (12). Une zone supplémentaire (27) du capuchon (20) est située sur l'extérieur de ce dernier et forme un manchon (29) qui, en utilisation, chevauche la surface extérieure (16) de la partie col (12). Le capuchon (20) est formé en acier déformable. L'invention concerne également un anneau (30) d'acier. Un joint (40) est formé de matériau déformable flottant. En utilisation, l'anneau (30) est placé sur la surface extérieure (16) de la partie col (12) et vient s'adapter à cette dernière. Le joint (40) est placé entre le capuchon (20) et la partie col (12). Le capuchon (20) est ensuite placé sur l'ouverture (18) du conteneur (10) et le retrait (22) est positionné dans l'ouverture (18) de sorte que la surface (28) de la zone d'épaulement (24) chevauche et soit opposée à la surface intérieure (14).
