Definitions

  • the present invention relates to a plastic bottle cap of the type that is anchored to the neck of the bottle by being clipped or snapped in place, also referred to as the "snap-on" type.
  • This type of cap has on its inner face a fixing projection that creates an interference with a collar situated in the neck of the bottle.
  • the said projection and the said collar create an interference that makes it impossible to remove the cap, the latter having been inserted under pressure.
  • the collar and the fixing projection interfere with its movement and prevent the removal of the cap.
  • both the projection and the collar have a surface of interference (i.e. contact) between each other that is perpendicular to the aforesaid axis.
  • this result cannot be obtained in caps produced by moulding, since in order to allow its release from the mould, the fixing projection and the inner side wall of the cap must form an angle greater than 90°. The value by which this angle exceeds 90° is known as the mould release angle.
  • Screw caps which have a seal that is broken at the moment of the first unscrewing of the cap, the seal being trapped by a collar on the neck of the bottle.
  • the seal is fixed by a flexible band (also known as a "flexband") situated in the tailpiece of the cap, which is inwardly foldable and interferes on its exit with the collar of the neck.
  • the band may be continuous, forming a ring, or intermittent, being formed as a plurality of band pieces arranged circumferentially. This type of cap is susceptible to being violated in two ways, either by effecting a horizontal displacement (i.e.
  • An aim of the present invention is to describe a cap using a snap-on fixing system that does not present the violability problems of the known caps.
  • the present invention consists of a cap made from plastic material, of the type that comprises a fixing projection for snapping on the inner face of its side wall, the said fixing projection having a surface for interfering with the collar, the said surface forming an angle greater than a right angle in relation to the side wall of the cap.
  • the cap further comprises, situated at the end of the side wall of the cap, an inwardly foldable flexible band, the said band having an inner supporting face that corresponds with the said interference surface, and an outer interference face that forms an angle equal to or less than 90° in relation to the said wall when the said interference surface and the said inner supporting face come into contact, the band terminating at its free end in a skirt that is arranged parallel to the said wall when the said interference surface and the said inner supporting face come into contact.
  • This innovative system can be used in any type of cap, including caps with a tearable precut seal integrated into their side wall. However, it offers greater advantages in snap-on caps, which have no tearable precut seal integrated into their side wall.
  • the projection has a second face at an angle of less than 180° to the interference surface
  • the band has a second inner contact face that corresponds with and comes into contact with the second face of the projection when the band is folded towards the inside of the cap.
  • a possible way of making the band flexible is by means of a weakening of the thickness in the area where the band joins with the cap.
  • Figure 1 shows a cap consisting of a pouring cap of the type often used for bottles of vegetable oil.
  • the cap -1- has an upper cover -2- and a lower part -3- intended to be anchored to the neck of the bottle -100- (see Figure 5 ).
  • the lower part -3- is anchored by means of a clipping or snap-on system, being placed under pressure in the neck -100- of a bottle.
  • the interference created by a clipping or snap-on system prevents the extraction of the whole of the cap.
  • the lower part -3- has a liquid outflow channel formed by the wall -33-.
  • the channel is stopped by a tearable membrane -36- created according to known techniques.
  • the tearable seal may be similar to that shown in the Spanish patent documents ES10002900U or ES2162585 .
  • the upper part -2- has a cylindrical fin -23- for stopping the channel formed by the wall -33- when the cap is in the closed position, thus preserving the sealing of the cap.
  • the system for anchoring the cap -1- to the bottle -100- is situated in the lower part -3-.
  • the first element of the system consists of a projection -31- situated in the inner side wall of the cap -32-.
  • the projection -31- has a first interference face -311-, which forms an obtuse angle with the inner side wall -32- and a second face -312- that forms an acute angle with the interference face -311-.
  • the inner lower edge of the side wall of the lower part -3- has a continuation in the form of a flexible band -4-.
  • the name "flexband” is used in the industry to indicate that the band is foldable towards the inside of the cap, without being an additional indication of any other characteristics or areas of the band, which could, for example, be rigid in nature.
  • the said flexible band -4- or "flexband” has a geometry that corresponds with the conjugate geometry of the projection -31- and the inner face -32- of the side wall of the cap.
  • the flexible band -4- has an inner supporting face -411- that comes into contact with the interference face -311- of the projection -31- when the flexible band folds towards the inside of the cap, and a second inner face -412- conjugate with the form of the second face -312- of the projection -31-.
  • the flexible band -4- of the example finishes in a skirt -42-, such that when the flexible band is folded towards the inside of the cap, and the interference face -311- of the projection -31- and the first inner contact face -411- of the flexible band -4- come into contact, the skirt -42- is parallel with the inner face -32- of the side wall of the cap.
  • the band 4 defines an outer interference face -43-.
  • This face is made to coincide approximately with the area of the band corresponding with the inner contact face -411-, and its function is to create an interference surface with a collar -101- on the neck of the bottle -100-.
  • the use of a foldable flexible band -4- makes it possible, in the folded position, for the interference surface -43- to be perpendicular to the axis of revolution of the cap or, which comes to the same thing, to the inner wall -32- of the cap, so that the interference with the interference surface -103- of the said interference collar -101- is completely perpendicular to an axial extraction movement.
  • the outer interference face -43- of the band -4- it would even be possible for the outer interference face -43- of the band -4- to form with the wall -32- an angle smaller than a right angle when the interference face -311- of the projection -31- and the inner contact face -411- of the band come into contact.
  • the present invention allows the said interference collar -101-situated in the neck of the bottle -100- to come into contact with the skirt -42- and hold it fast against the inner wall -32- of the cap. To favour this effect, it is possible to lower the wall -32- in the area that receives the skirt -42-.
  • the band -4- is joined to the lower part -3- of the cap -1- by means of a narrowing -41-of the wall, which allows the band to be flexible and provides a degree of resistance and rigidity in the other areas of the band -4-.
  • the cap rests on a larger collar -102- of the bottle -100-.
  • This collar -102- also helps, additionally, to prevent violation of the cap by access to the area between the bottle and the cap.
  • the cap can be released from the mould without any problems, since the standard mould release angles can be observed.
  • the flexible band -4- can be folded inwards, leaving the cap ready for fixing to a bottle -100- by snapping in place.
  • the type of cap particularly its upper part, may for example be of any known type. It is also possible, in particular, to omit the second inner contact face of the band, in which case the narrowing where the band is joined to the cap can be minimised or completely eliminated, among other examples.
