Definitions

  • a closure for a container with an internal undercut in its neck [22] Filed: July 7, 1970 consists in a flexible main member and rigid auxiliary member.
  • the main member has a top flange which seats on the mouth lzll Appl' 52905 of the container and a stopper portion in the form of an inner and an outer coaxial wall, separated by a clearance.
  • a bulge is [30] Foreign A li ti Priority D t formed on the outer surface of the outer wall, and when the closure is fitted in place engages in the undercut.
  • the auxl o are iliary member is pressed further in to force the projection on its tubular wall to pass the projection on the outer wall of the [56]
  • the invention relates to a closure for a container such as a bottle of a type in which the container neck has an internal undercut.
  • An object of the invention is to provide a closure for a container of this type which is simple, tough and inexpensive in construction and sealingly closes the container even if it contains an aerated drink, and is provided with a safety seal which must be severed before the closure can be removed.
  • a further object of the invention is to provide a closure of the above-mentioned type which is easily fitted to the container, and the seal of which can easily be severed, even by hand, in order to open the container initially.
  • a further object of the invention is to provide a closure of the above-mentioned type which may be used for reclosing the container after the first opening, and so protect the contents,
  • the invention provides a closure for a container having a mouth and a neck with an internal undercut, the closure comprising a main member of flexible plastics having a top flange adapted to seat on the container mouth and a stopper portion adapted to seat on the container neck, the stopper portion comprising an outer and an inner wall separated by a clearance, the outer wall being joined at its upper end to the top flange and at its lower end to the lower end of the inner wall, the outer wall having a shaped external circumferential projection adapted to engage in the undercut in the container; and an auxiliary member of rigid plastics comprising a top cover and a tubular wall connected at its upper end to the top cover and having at its lower end a shaped external circumferential projection; the tubular wall of the auxiliary member being adapted on closing of the container to extend into the clearance between the outer and inner walls of the main member to a position in which the circumferential projections on the main and auxiliary members register with one another to avoid removal of the closure; and on opening of the container to extend
  • FIG. 1 is an exploded partly sectioned side view of a closure for a bottle or similar container
  • FIG, 2 is a partial plan view of one member of the closure of FIG. 1;
  • FIG. 3 is a plan view of a second member of the closure of FIG. 1;
  • FIGS. 4, 5, 6 and 7 are axial sectional views showing various steps in the fitting of the closure to a bottle and in the initial opening of the bottle.
  • a closure for a bottle or similar container comprises a main member 1 molded from flexible plastics and an auxiliary member 13 molded from rigid plastics.
  • the closure can be fitted to a bottle or similar container 19 formed with a neck 20 which is sharply restricted to form an annular internal undercut 21.
  • the main member I of the closure comprises a stopper portion in the form of an outer annular wall 2 and an inner annular wall 6 coaxial with each other and connected'to each other at their lower ends by a shaped bottom portion of high flexibility.
  • the inner wall 6 is closed at its upper end by a transverse top wall 7.
  • the outer wall 2 is provided with external flexible annular tabs 3 adapted to improve sealing of the closure against the neck of the bottle so as to withstand any gas pressure evolving from the contents.
  • the outer cylindrical wall 2 is provided near its bottom with a circumferential projection in the form ofa shaped annular bulge 4 adapted to engage in the undercut 21 on the bottle when the closure is forced into the neck 20.
  • the two coaxial walls 2, 6 of the main member 1 are separated by an annular clearance that is open upwardly. Longitudinally extending ribs 8, 9 project into this clearance from the inner wall faces to facilitate sliding of a member to be described below.
  • the main member 1 is provided at the top with a flange l0 having an outer milled region 11 for easy gripping in order to open the bottle, the flange I0 surrounding a shallow inner annular rebate I2.
  • the outer wall 2 is joined at its upper end to the top flange 10.
  • the auxiliary member 13 of rigid plastics comprises a tubular wall I4 which is provided near its lower end with a circumferential projection 15 in the form of a ridge with a cylindrical edge.
  • the cross section of the ridge is in the form of an outwardly projection tooth.
  • the annular wall 14 is closed at its upper end by a flat top wall 16.
  • auxiliary member 13 is connected to a surrounding ring 17 by a plurality of frangible radial webs l8 collectively forming a safety seal.
  • the outer wall of the main member 1 is deformed to permit the annular projection 4 to engage in the undercut 21 (FIG. 5).
  • This step is carried out by exerting an axial thrust on the flange 10 of the main member 1.
  • the device is naturally so dimensioned that, when the flange 10 of the main member 1 contacts the edge of the mouth of the bottle 19, the annular projection 4 has previously been engaged in the undercut 2].
  • the closure is subsequently completed by exerting an axial thrust on the auxiliary member 13 to move it relatively into the main member 1.
  • the ring 17 of the auxiliary member accurately fits into the rebate 12 formed in the flange 10 of the main member.
  • the outer annular projection 15 on the tubular wall 14 of the auxiliary member extends to the same level as the annular projection 4 on the outer cylindrical wall 2, as shown in FIG. 6.
  • the tight fit of the closure is enhanced by bending of the radial tabs 3 which extend from the outer wall 2 of the main member 1.
  • a forceful axial thrust is exerted downwardly on the central portion of the auxiliary member, more particularly on the top wall 16, in order to fracture the webs 18.
  • the central portion formed by the top wall 16 and tubular wall 14 can then be displaced downwardly as shown in FIG. 7.
  • annular projection 15 on the auxiliary member is no longer in register with the annular projection 4 on the flexible wall on the main member and the closure can be removed as a whole from the bottle by gripping the main member at its milled collar 10, 11 and manipulating it away from the container.
  • Fracture of the webs l8 reveals the fact that the closure has been opened, so that tampering with the container cannot pass unnoticed.
  • the closure may be used after the first opening for reclosing the container without, however, reestablishing the former safety closure conditions.
  • a closure for a container having a mouth and a neck with an internal undercut comprising a main member of flexible plastics having a top flange adapted to seat on the container mouth and a stopper portion adapted to seat on the container neck, the stopper portion comprising an outer and an inner walls separated by a clearance, the outer wall being joined at its upper end to the top flange and at its lower end to the lower end of the inner wall, the outer wall having a shaped external circumferential projection adapted to engage in the undercut in the container; and an auxiliary member of rigid plastics comprising a top cover and a tubular wall connected at its upper end to the top cover and having at its lower end a shaped external circumferential projection; the tubular wall of the auxiliary member being adapted on closing of the container to extend into the clearance between the outer and inner walls of the main member to a position in which the circumferential projections on the main and auxiliary members register with one another to avoid removal of the closure; and on opening of the container to extend further into
  • top flange of the main member is formed with an upwardly open annular rebate and the top cover of the auxiliary member is surrounded by an outer ring connected to the top cover by frangible web means, the outer ring being adapted to seat in the rebate in the top flange of the main member when the closure is fitted on the container, fracture of the frangible web means being necessary to allow the tubular wall of the auxiliary member to be forced further downward into the clearance between the outer and inner walls of the main member for removal of the closure.
