Definitions

  • the invention relates to a multi-use bottle and cap assembly according to the pre-characterising portion of claim 1.
  • French patent application 2,528,393 which corresponds to the pre-characterising portion of claim 1, discloses a bottle and cap assembly for bottles containing sterilized liquids capable of supporting high sterilization temperatures comprising a cap and a stopper of very flexible material located therein.
  • the stopper according to this French patent application has a conical shape at its tip followed by a straight cylindrical portion, then by a conical peripheral step and then by an upper portion of wider diametre.
  • the cap according to this French patent application, has at its bottom, a circular recess and an abutment surface.
  • the stopper acts basically as a conventional cork-stopper.
  • the upper portion of the stopper is pressed into the circular recess provided in the cap bottom so that, when the cap is unscrewed, the stopper will be pulled out of the bottle neck by the vacuum caused adherence between the cap and the stopper.
  • the cap is also provided with abutments which prevent the stopper from falling out when unscrewed.
  • Such cap and bottle assembly is, however not capable of supporting frequent screwing and unscrewing as the stopper is obviously deformed and subject to stresses caused by its friction with the bottle mouth rim and/or the cap bottom, and to torsions which lead to capillar leaks and deformations and the consequent loss of airtightness conditions, due to that the stopper is forced to turn around together with the cap or that the cap turns around on the stopper.
  • the flexible stopper if strongly stuck in the bottle neck, may remain retained therein due to the loss of its vacuum caused adherence with the cap so that the stopper, due to its flexible nature will slip over the abutment provided within the cap, so that the stopper must then be pulled out manually, which causes further deformation and danger of leaks of the assembly.
  • the present invention as claimed is intended to provide an inexpensive cap and bottle assembly capable of supporting frequent screwing on and unscrewing from the bottle containing gaseous liquids like sparkling water, lemonade etc., i.e. carbonated liquids causing pressure within the bottle, without losing its airtight sealing qualities, and wherein the stopper is always retained within the cap.
  • gaseous liquids like sparkling water, lemonade etc., i.e. carbonated liquids causing pressure within the bottle, without losing its airtight sealing qualities, and wherein the stopper is always retained within the cap.
  • the invention which is defined by claim 1, advantageously solves these goals by providing an inexpensive, simple and easy to handle bottle and cap assembly which perfectly supports frequent screwing and unscrewing without any loss of airtightness as any torsion or deformation of the stopper leading to capillar leaks is practically reduced to zero.
  • Figure 1 is a side elevational view of the cap and the stopper disconnected from each other;
  • Figure 2 is a side elevational view of the assembled cap and stopper screwed on a bottle.
  • the figures show a cap having on the inside of its vertical walls (1) a screwthreading (2) whilst on the outside thereof there are longitudinal ribs (3) to provide a better grip.
  • a stopper is located in a space (5) existing between cap bottom (4) and the upper portion of screwthread (2.)
  • the cap bottom (4) In the centre of the cap bottom (4) there is a convex raised part or abutment (6.)
  • the cap is provided with a sealing flange (7) joined to the cap body by easy to break points (8.)
  • the stopper loosely lodged inside the cap comprises a flange like part (9) which downwardly extends into a conical sealing skirt (10.)
  • the flange (9) and the skirt (10) are separated by a peripheral conical step (11.)
