Definitions

  • the present stopper is for attachment to containers having a neck with external threads and which stopper when assembled to said neck cannot be readily detached therefrom.
  • the stopper includes a tubular body insertable in the container neck, a hollow plug member insertable in said tubular body, an internally threaded cap for threaded engagement with said neck and having a central opening in which the top of said plug member mates and having a skirt and annular rib for cooperating with said inner plug and tubular body to provide three points of lateral sealing around said inner plug to prevent the undesired escape of material from said container other than through said cap center opening.
  • This invention relates to a captive stopper assembly for tubes or any containers provided with a screw neck, and more particularly for tubes adapted to be flattened, as disclosed in my prior U.S. Patent No. 3,305,127 of Feb. 21, 1967.
  • the known stopper assembly disclosed in the above patent application comprises essentially a tubular body partly engaging the tube neck, an inner tubular or plug member formed with lateral apertures and partly engaging the inner space of the body so as to expand inner projections thereof within the tube and beneath said neck for locking said body in said tube, and finally a cap formed with an upper central hole which is screwed on the neck of the container to enclose the resulting assembly.
  • the product kept in the container may escape therefrom through the plug member apertures and through the central hole of the cap, the complete removal of this cap being prevented by a circular shoulder or bead formed at the bottom of the cap and movable circularly about the neck of the container in a recess or groove formed to this end beneath the screw-threaded portion of said neck.
  • plug member and the cap are advantageously made of relatively flexible or elastic plastic materials.
  • a first feature characterizing this invention consists in providing said annular bead projecting within the cap above the tapped portion of the cap instead of at the bottom thereof, thus permitting the movement of this head about the tubular body portion externally of the container, beneath an upper peripheral flange of said tubular body, whereby the operation of the device, from which the captive characteristic is derived, is no more dependent on the accurate machining of a groove on the neck of the container.
  • the lateral seal is advantageously provided, within an open tubular extension of said plug member, by an inner skirt depending from the top of the cap.
  • the axial movement of the cap in the closing direction is advantageously limited by a cylindrical collar depending from the top of said cap and fitting around the tubular extension of said inner plug member while partaking in the lateral fluidtightness of the device by abutting in its innermost position against the upper edge of said tubular body.
  • the reference numeral 31 designates the upper end of a tube adapted to be flattened and to be provided with the captive plug assembly of this invention.
  • the tube comprises a screw-threaded neck 32 in which the tubular body 33 is engaged, this body 33 carrying at its lower end lugs 34 adapted to expand beneath the outflared or tapered portion 31 at the bottom of neck 32 when the hollow plug member 35 is inserted into the tubular body 33 according to the assembly method disclosed in the Patent No. 3,305,127.
  • the tubular body 33 comprises a shoulder 36 engageable by an outer flange 37 of said plug member, an open-top tubular extension or cylindrical collar 38 extending upwards from said flange.
  • This flange 37 projects slightly outwards from the outer peripheral wall of said collar 38 and is retained within the tubular body 33 by resiliently engaging the lower edge of an inner projection 39 which may be either continuous or divided into several fractions or sectors, formed on the inner face of an upper widened portion 48 of said tubular body 33.
  • the upper edge of the tubular body 33 is formed with an outer abutmenvforming peripheral head 43 adapted to retain the cap as will be explained presently.
  • the closing cap is moulded from suitable plastic material (like the tubular body and the plug member) to have an adequate elasticity and comprises a top 45 formed with a central aperture 46 adapted to engage in a fluid-tight manner the outer wall of the upper portion 42 of said plug member. It further comprises a peripheral lateral wall 4'7 depending from the outer periphery of said top 45, and a widened base portion 48 formed with inner screw threads along a certain portion 49 of its height which is inferior to the total height of the screw-threaded portion of the neck of the container.
  • an inner skirt 50 Depending from the top wall 45 of the cap is an inner skirt 50 adapted to slide within the tubular extension or collar 38 and form a leak-proof joint therewith. Between the skirt 50 and the lateral wall 47 an annuiar rib 51 is also provided on the inner face of cap 45 and adapted to the end of the screwing movement to engage the upper edge of the tubular body to limit the cap movement during the screwing thereof for closing the tube.
  • the inner surface of the cap comprises an annular retaining bead 52 moulded integrally with the cap and adapted to move around the upper portion 40 of the tubular body beneath the peripheral bead 41 retaining its companion bead 52 and therefore the cap upon completion of the permissible unscrewing or cap opening movement.
  • the permissible axial stroke of bead 52 between its lowermost position shown in the drawing and its uppermost position in which it abuts against its companion abutment-forming bead 4-1 is advantageously slightly inferior to the height of the tapped portion of the cap which overlies the bead 52 in order to afford a certain axial compression of the tapped portion at the end of the unscrewing movement, thus ensuring the automatic return of the tapped portion 49 of the cap to the position of proper relative engagement with the neck 32 when screwing in the cap for reclosing the tube, without requiring the application of any axial thrust on this cap.
  • the cap In the fully closed position shown in the drawing the cap has been screwed home until its annular rib 51 engages the upper edge of the tubular body, the tapped portion 49 of the cap having engaged one fraction of the height of the screw-threaded portion of neck 32 downwards.
  • the height of this screw-threaded portion is slightly greater than that of said tapped portion, thus affording a suth'cient tolerance in machining the tube neck.
  • the retaining head 52 Shortly before the cap unscrewing movement is completed the retaining head 52 is stopped by the annular abutment 41 of the tubular body and since the permissible axial stroke of this head is slightly shorter than the height of the tapped portion 4?, completing the unscrewing movement will apply a vertical compressive force to the tapped portion 49 until it escapes from the screw-threaded portion of neck 32 and is subjected to a kind of prestress whereby it will automatically re-engage the screw-threaded portion when the cap is re-screwed.
  • a stopper for a receptacle provided with an externally screw-threaded neck comprising a tubular body of a resilient synthetic plastic material having an enlarged upper portion capable of being seated on the end of said neck with an outwardly extending peripheral bead at the end thereof and a cylindrical skirt depending from said upper portion and capable of extending into said neck, said skirt having bottom lugs projecting in wardly for being mounted within said receptacle below said neck, an inner hollow plug member of a resilient synthetic plastic material which is closed at its top, has lateral openings below said top and a tubular collar surrounding and radially spaced from, the upper portion of said hollow plug member, said inner hollow plug member extending within said skirt of the tubular body and expanding outwardly the bottom of said skirt provided with said lugs, an internally screw-threaded cap of a resilient synthetic plastic material capable of being screwed on said neck and provided at its upper end with a top having a central hole for receiving the closed top of said inner hollow plug member when said cap is fully screw
