Definitions

  • the present invention is related to an improved closure for bottles, fundamentally applicable to that type of stopper formed by threaded capsules mounted over the corresponding bottle mouth, the said bottle destined to contain liquid products.
  • the closure presents the particularity of creating a totally leak-proof medium to prevent liquid escape, even after successive openings.
  • Normal bottle closures that have to be opened and closed many times are based on a capsule, normally of a plastic material, which threads onto the bottle mouth.
  • the leak-tightness is obtained in several ways; in some cases by means of flexible and/or elastic elements adapting to any irregularity or misalignment.
  • the former elements can include washers, cork or plastic material disks functioning as a seal.
  • some rings or tubular divisions are mounted in the bottom of the capsule and adapt to the rim of the bottle mouth as if they were tongues.
  • the closure is conceived to obtain total leak-tightness to prevent liquid escaping, even though the bottle is opened many times and the former being based on an extremely simple structure, resolving the problems and disadvantages presented by conventional closures.
  • the closure, object of the invention presents as a fundamental characteristic, the inclusion of a discoidal assembly of flexible material having a diametre greater than the bottom of the corresponding capsule which is applied by threading over the bottle-neck, such that when it is seated over the latter the disk oversizing will create a semi-enveloping with respect to the upper and external edge of the bottle-neck.
  • all possibility of escape is eliminated and besides, a greater protection of the bottle against possible blows is obtained, due to this interposed flexible element which reduces breakage risks.
  • the mentioned disk (4) constitutes an adjustable and semi-enveloping element with respect to the upper or external edge (5) of the bottle neck, such that as the assembly diametre (4) is greater than the internal diametre of the bottom (3), and therefore, greater than the external diametre of the mouth or bottle-neck, it is unquestionable that the said disk (4) will externally adapt itself, increasing the closure surface, hence eliminating possibilities of escape. In turn a greater protection in this area or upper edge (5) of the neck will be obtained against possible blows, since a flexible element, formed by the salient part of the disk (4) remains interposed, hence reducing breakage risks.
