Definitions

  • the invention proposes to provide a ring, which is loosely surrounded by the spring and which has'pins extending between the windings of the spring. These pins cooperate with guiding surfaces on the head to permit axial movement of the ring while keeping it centered coaxially with the channel.
  • the ring and the spring can be open to provide a lateral opening for the sideways insertion of caps with a downwardly'extending stopper portion.
  • This invention relates to an improvement in machines for fitting closures on bottles by pressure, comprising a vertical guiding opening for the bottle neck, a lateral opening in the upper end of the guide opening for inserting the closures in the latter,'a pressure member movable from above into the guide opening and a radially extensible supporting member extending radially into the guide opening for supporting the bottle closure before pressing it onto the bottle, said supporting member being in the form of an annular spring placed in a peripheral groove surrounding the guide opening.
  • the distance by which the annular spring can project into the guide opening is strongly limited by the fact, that the abutments themselves cannot be allowed to extend radially into the guide opening and must have a certain radial thickness to receive the necessary strength.
  • the invention is based on the principles of providing supporting abutments limiting the contraction of the annular spring towards the axis of the guide opening in such manner, that they instead of cooperating with the outer side of the spring facing the guide opening, cooperate with the inside of the parts of the windings of the spring situated within the groove.
  • the rin g which by its gravity rests against the spring windings acts as a damper on vibrations within the spring.
  • the device further makes it possible to execute the spring open or with an interruption along its periphery for the insertion of closures, having a long stopper portion extending a considerable distance below an abutment flange adapted to abut against the upper border of the bottle mouth. This makes it possible to fit the closure with a reduced axial height above the annular spring of the lateral opening for inserting the closures and with a relatively reduced axial stroke of the pressure member and to insert the closures into the machine by simple straight horizontal movement to its resting position on the annular spring.
  • FIG. 1 is an axial vertical sectional view through the part of the machine comprising the guide opening and the pressure member.
  • FIG. 2 is plane view of the annular spring and the inner ring associated therewith.
  • FIG. 3 is a view similar to FIG. 1 of a device with an open annular spring forclosures having an oblong stopper portion.
  • FIG. 4 is a view similar to FIG. 2 of the annular spring and the inner ring of the device according to FIG. '4.
  • the device has a downwards conically widening guide opening 1, in which the neck of a bottle to be provided with a closure is to be inserted from below.
  • a lateral opening 2 At the upper end of the guide opening 1 there is a lateral opening 2, through which the bottle closures 3 are to be inserted in any known manner.
  • a pressure member or piston 4 is vertically reciprocatably guided in the upper part of the guide opening for pressing the closure 3 on the mouth of a bottle inserted from below.
  • annularspring 6 which is extensible towards the bottom of the groove 5 and which has a portion extending into the guide opening to form an abutment for supporting the closure 3 in centered position.
  • the windings of the annular spring 6 enclose with a certain play a thoroidal, solid ring 7, which is slidably guided in vertical direction along the bottom wall 8 of the groove 5 by means of pins 9 extending radially from the ring 7 between the windings of the spring.
  • FIGS. 1 and 2 The embodiment illustrated in FIGS. 1 and 2 is specially adapted for flat closures of the cap-type generally used for closing bottles containing carbonated beverages in which a stopper portion to be inserted into the bottle neck practically or not at all extends beyond the lower border of the collar portion of the cap.
  • a reduction of the total height of the machine, a simplification of the guiding of the closure to the position ready for fitting on the bottle, reduction of the necessary working stroke of the piston 4 and a simpler and more secure function of the machine are obtained according to this embodiment by forming the spring and the plain ring 7 therein as open rings with a space between the free ends thereof of sufficient width to permit the passage of the stopper portion 11 of the closure 3 through said space.
  • the flange 10 of the closure 3 is shown to have a slightly outwardly protruding upper edge which rests upon the inwards projecting portion of the annular spring to maintain the closure in vertical position and with the lower part of the periphery of the flange 10 centered within the inside of the annular spring.
  • the ends of the spring 6 can be hooked on said pins so as to permit the necessary initial tensioning of the spring, so that it can form an inwards projecting, resiliently extensible support for the closure.
  • One of the pins preferably the one with the reference 9a in FIG. 4, extends into a recess in the bottom surface 8 of the groove to prevent the ring 7 from being turned.
  • a machine for fitting closures on bottles by pressure comprising a vertical guide opening for the bottle neck, a lateral opening in the upper part of the guide opening for inserting the closures in the latter, a pressure member vertically displaceably guided in the upper end of the guide opening and a radially resilient support projecting radially into the guide opening for supporting the closures before pressing and having the form of an annular spring located within a groove peripherally surrounding the guide opening; a thoroidal inner ring surrounded with a play by the windings of the annular spring and centered relative to the guide opening by abutments extending from the thoroidal ring between the windings of the annular spring and engaging guiding surfaces within the groove.
  • both the annular spring and the inner ring are interrupted to form an opening between two free ends for the sideways insertion of the downward extending portion of bottle closures having an upper flange to be inserted above the annular spring.
