Definitions

  • Stoppers made from cork obtained from the cork oak have traditionally been used to close bottles such as wine bottles. In use, the cork is inserted into the neck of the bottle where its inherent elasticity enables it to expand to seal the neck such that the ingress of air is reduced and the contents of the bottle are prevented from escaping from the bottle.
  • numerous disadvantages associated with the use of natural corks have been identified, such as their cost, scarcity, and unequal quality. Accordingly, alternatives to natural cork have been sought.
  • One alternative solution is to produce a stopper wholly from synthetic materials. In general such stoppers are produced to resemble the natural corks in color to yield a higher acceptability from the consumer. Again, mono-component synthetic stoppers made e.g.
  • core-skin stoppers could theoretically be produced by injection molding, the production costs would be too high. It is generally preferred to produce core-skin stoppers by co-extrusion thus forming a continuous elongated member which is thereafter cut at the desired length to form the individual stoppers as also explained in US2003/0161985 . In this case, the chamfers at the edges of the stoppers must be formed after -or upon- cutting the elongated member into individual stoppers.
  • EP-A1-1493681 discloses a process for producing synthetic bi-layered bottle closures provided with chamfered edges wherein the beveled ends are obtained by a grinding process.
  • a problem with the grinding process is that as material is ground away from the edges, shavings and dust may electrostatically adhere to the surfaces of the stopper and thus contaminate the liquid contained in the container the stopper is inserted into.
  • the present invention also concerns a hollow barrel for tightly holding and centring a cylindrical stopper suitable for the apparatus as above-described, consisting of a hollow cylinder of length and diameter larger than the stopper to be engaged therein, wherein the hollow barrel comprises at least nine spherical balls mounted in, and protruding from recesses located in the inner wall of the barrel, disposed on at least three points round its circumference to define a polygonal passageway normal to the barrel's axis of revolution, and distributed on at least three rows along the length of the barrel, the balls being mounted so as to resiliently engage deeper into their corresponding recesses when pressed in, thus enlarging the passage defined thereby to accommodate the stopper.
  • the hollow barrel comprises at least nine spherical balls mounted in, and protruding from recesses located in the inner wall of the barrel, disposed on at least three points round its circumference to define a polygonal passageway normal to the barrel's axis of revolution, and distributed on at least three rows along the length of
  • the carousel 6 shall be associated with means for rotating the carousel 6 and shall preferably comprise at least three cylindrical hollow barrels 11, 21, 31.
  • the dispensing station 4 and loading station 1 preferably correspond to a same position of the carousel 6, and are located at opposite sides of the panel.
  • the carousel 6 of the present invention comprises cylindrical hollow barrels 11, 21, 31 which function is to hold in place the stoppers to be chamfered and to rotate during the chamfering operations.
  • Theoretically a single barrel hopping from one station to the next one would suffice to successfully complete the chamfering operation, but in practice this is not satisfactory for insufficient production rates.
  • the carousel 6 comprises enough barrels distributed round its circumference to occupy all the stations 1-4 at each rotational increment.
  • the resilient means 14 may be a spring or an elastomeric element.
  • the elastomeric element has the shape of a diabolo, i.e., a prism of revolution with a restricted section in the middle.
  • the force required to engage the ball into the recess such as to allow the passage of a stopper must be sufficiently low to permit an easy introduction of a fresh stopper 10 into, and extraction of a fully chamfered stopper 10b out of the barrel, and sufficiently high so as to hold the stopper in place during the chamfering operations.
  • the balls 12 are separated from the resilient means 14 by a low friction element (e.g., in PTFE, POM, HDPE) to facilitate the translation of the stopper along the barrel by allowing a certain level of rotation of the balls. Care should be taken that the level of rotation of the balls should be sufficiently low so as to ensure that the stoppers follow the rotational movement of the barrel during a chamfering operation.
  • a low friction element e.g., in PTFE, POM, HDPE
  • the second chamfering station 3 is a mirror reproduction of the first chamfering station 2 and comprises the same elements but disposed on opposite sides of the carousel.
  • barrel 11 faces means 35, preferably a piston, which pushes the stopper 10a partly out of the barrel 11 until it reaches stopping means 38 to expose the un-chamfered edge still to be chamfered to a rotating blade 36a (cf. Fig.1 &6).
  • the exposed edge is chamfered over its whole circumference (cf. Fig.2 ).
  • a fourth barrel is not necessary to complete the chamfering cycle as first barrel 11 faces on one side thereof the dispensing station 4 and on the other side the loading station 1. It is possible, albeit less preferred, to have loading station 1 and dispensing station 4 corresponding to different positions on the carousel, but then a fourth barrel is required to ensure that each station is occupied by a barrel at each stage of the chamfering cycle.
  • stopper 10b having both ends chamfered is pushed out of the barrel 11.
  • this operation is preferably carried out by introducing a fresh stopper 10 from the feeding line 5, thus expulsing the chamfered stopper 10b (cf. Fig.1 &4).
  • a piston may be used to simply push out the chamfered stopper, but this solution is less preferred as it requires a larger number of barrels and a larger carousel to accommodate a sequence of four stops, instead of three as illustrated in Fig.1 .
  • Providing a carousel with 3 x N barrels serving N station sequences 1-4 increases by a factor N the production rate or output of the apparatus.
