Definitions

  • the present invention relates to a closure cap with screw for a bottle neck, comprising a cap body and a seal in flexible material added in said body to cooperate with effect sealing with the neck when screwing the cap onto the latter.
  • Known screw caps can be classified into two groups from the point of view of the means provided for sealing bottle necks, namely caps with attached seals and capsules without added seal.
  • a seal in a more flexible than the material of the capsule body which can for example be metal or plastic, is attached in said body so as to be tightened either only against the end of the neck, or against both the end and the outer lateral surface of the neck.
  • sealing means formed for example by lips, skirts, etc. are molded in one piece with the plastic capsule body and either cooperate with the end of the neck, with the inside surface of the neck or with the outer surface of the neck, that is to say both with the end and the surface inside of the neck or with both the end and the outer surface of the neck.
  • bottles in glass are usually checked on the outside diameter and not on the inside diameter of the neck.
  • the present invention relates to a screw closure cap capable of ensuring a tight closure also on necks of bottles with large tolerance intervals and / or shards or other defects.
  • the screw closure cap, object of the invention, for a bottle neck includes a cap body and a material seal flexible, attached in said body to cooperate with sealing effect with the neck of the bottle when screwing the cap onto it.
  • the seal is shaped so as to cooperate at the same time with the end, with the outer side surface and with the surface inner side of the bottle neck.
  • the seal comprises a first annular part substantially flat intended to bear against the end of the neck of bottle, a second annular part projecting in an axial direction on the outer edge of said first annular part, for bearing against the outer surface of the bottle neck, and a third annular part projecting in the same axial direction as said second part, on the edge interior of said first part, for bearing against the interior surface bottle neck.
  • the second annular part of the seal preferably has a inner surface in the shape of a truncated cone diverging from of said first annular part.
  • the third part annular seal advantageously has an outer surface ranging by converging in a truncated cone from the first annular part.
  • the third part ring seal has a generally transverse profile triangular, preferably substantially in an isosceles triangle.
  • a bottle neck 1 intended to be closed by a cap 2 has a substantially cylindrical inner side surface 3, a end surface 4 and an external lateral surface 5 provided with a net 6 and, below the latter, an annular outer rim 7. Above of the net, the outer lateral surface 5 has an end portion 5a slightly smaller in diameter.
  • the capsule 2 comprises a capsule body 8 molded from material plastic, for example polypropylene.
  • the body 8 having a shape general of bucket comprises an end wall 9 or circular bottom and a skirt 13 of generally cylindrical shape, projecting from the wall end 9.
  • the skirt 10 has a thread 11 on its inner face and is extended at its free end remote from the end wall 9 by a inviolability or guarantee ring 12 connected to the skirt 10 by a zone frangible not represented, constituted for example by several bridges distributed around the circumference or by a thinned annular zone, as this is well known.
  • the skirt 10 has, on its outer face, a knurling 13 facilitating the screwing and unscrewing of the capsule.
  • the capsule body 8 is provided internally, on the face inside of the end wall 9, of a seal 14 attached in a material softer than the material of the body 8, for example a material based on low density polyethylene which may have a Shore A hardness included between 30 and 100, preferably between 60 and 90.
  • the seal 14 can be of preferably hot molded by compression in the capsule body 8, so as to adhere to the wall 9 of the body 8.
  • an undercut part 15 is provided on the body 8, in the area of connection of the skirt 10 to the end wall 9, at the edge outside of gasket 14.
  • the seal 14 of circular shape comprises a central part 16 flat and thin successively surrounded outwards by a part annular 17 of triangular profile, projecting from the opposing part 16 at the end wall 9, a substantially flat annular part 18 and a annular part 19 in the form of a protruding rim in the same direction as the part 17.
  • the annular part 17 can have a profile substantially in an isosceles triangle, with an angle at the apex comprised by example between about 20 and 50 °, preferably between about 30 and 40 °.
  • the diameter of the circle passing through the top of part 17 corresponds to preferably substantially to the diameter of the interior surface 3 of the neck 1 to butcher.
  • the height (projection) of the annular part 17 can be by example between 0.5 times and 2 times the thickness of neck 1 and be preferably substantially equal to this thickness.
  • the annular portion 19 in the form of a rim of the seal 14, which provides mechanical maintenance of the seal 14 in cooperation with the undercut 15 of the body 8, has a substantially frustoconical internal flank diverging at an angle of between about 30 and 60 °, preferably at an angle of about 40 °.
  • the free end of part 19 is on a circle whose diameter is slightly greater than the diameter of the end portion 5a of the outer surface 5 of the neck, while the opposite end of the inner flank of the part 19 is located on a circle whose diameter is less than the diameter of the end portion 5a from the surface 5.
  • the annular part 18 of the seal 14 between the two parts 17 and 19 has a width less than the thickness of the neck 1 at the location of the end part 5a and may advantageously have a thickness (axial) greater than the thickness of the central part 16.
  • the thickness of the part 18 may preferably be equal to the at least twice the thickness of the central part 16, which does not intervene not in the sealing function of the neck 1.
  • the warranty ring 12 is retained under the rim 7 of the neck 1.
  • the annular part 17 of the seal, bearing against the interior surface 3 of the neck 1 is elastically deformed inwards, part 18 bearing against the end surface 4 of the neck 1 is resiliently axially compressed and the part 19 bearing against the external surface 5 neck 1 (in this case against the end portion 5a) is elastically compressed towards the outside.
  • annular part 17 of the seal cooperating with the surface inner 3 of neck l could have a different profile than that shown, for example a profile, in a right triangle, provided that the outer surface of said annular part constitutes an annular flank converge.
  • the surfaces through which the annular parts 17 and 19 coming into contact with the neck could also have generators curvilinear defining, for example, concave or convex flanks.
