Definitions

  • This invention relates to closure.caps for alternately opening and closing a discharge passage for flowable material extending between the interior and exterior of a container.
  • closure caps are typically used on containers of flowable material, e.g. soap, detergent, shampoo, etc., for closing and sealing the container when in disuse and for being opened to permit the contents of the container to be dispensed as desired by the user.
  • flowable material e.g. soap, detergent, shampoo, etc.
  • closure caps are disclosed in U.S. Patent No. 3,276,640 issued October 4, 1966 to Kessler, U.S. Patent No. 3,439,843 issued April 22, 1969 to Corsette, U.S. Patent No. 3,516,.581 to M icallef issued June 23, 1970, and U.S. Patent No. 3,572,559 to Stull issued March 30, 1971.
  • closure caps As further known to those skilled in the art, a common problem associated with such closure caps is that the component members between which relative movement is provided to open and close the passage do not remain in fluid tight engagement during the act of dispensing or during the acts of opening and closing the passage. This lack of fluid-tight engagement permits the dispensed flowable material to escape between the component members between which relative movement is provided and the material accumulates on the exterior and interior of the closure cap providing an unsightly and undesirably messy condition and, depending upon the material being dispensed, sometimes an unsanitary condition.
  • closure caps known to the prior art which includes a lever mounted for angular movement in a plane perpendicular to the lid for closing the container and wherein the lever is provided with a downwardly extending member in engagement with an upwardly extending member mounted stationarily on the lid; the interiors of such members are provided, respectively, with ducts each of which forms a portion of the discharge passage.
  • FIG. 1 there is shown prior art closure cap 10 mounted threadedly on the neck of a container 12 and which closure cap 10 upon being opened as shown in FIG. 2 provides a discharge path indicated by the arrows for communicating the interior of the container 12 with the exterior thereof for dispens ing flowable material contained therein.
  • the closure cap includes a lever 14 mounted pivotally at 16 with the forward portion of the lever including downwardly extending members 18 for sealingly engaging the upper portion of an upwardly extending and stationarily mounted member 20 to close the discharge path. For dispensing, the rearward portion of the lever 14 is forced downwardly causing the forward portion of the lever to pivot upwardly, as shown in FIG.
  • the present invention is an improvement of the closure cap of the-type illustrated in U.S. Patent No. 3,516,581 and shown in FIGS. 1-4 of the accompanying drawings, and provides a novel and improved closure cap structure wherein translational or straight-line relative movement is provided between the members which are in telescopic, sliding engagement, upon the improved closure cap being in the dispensing position and during the acts of moving the cap between the dispensing and sealing positions whereby the telescopically interconnected members remain in fluid-tight engagement.
  • the present invention provides an improved closure cap wherein one of the two members in telescopic, sliding engagement is provided with a resilient member which is compressed upon the associated lever being depressed to close the discharge passage and which resilient member upon being compressed provides force to the other of the two members to force the two members into sealing or fluid-tight engagement during disuse whereby prevention of fluid escape is enhanced.
  • the closure cap 2.0 ist generally of cylindrical shape or configuration , but may also have a generally rectangular shape, if desired.
  • the closure cap 20 comprises two parts, namely a generally cylindrically shaped lower portion 21 and a generally disk-shaped upper portion or lever 22.
  • the lower portion 21 is provided with internal threads, as shown, for threaded engagement with the external threads provided on the neck 23 of a container 24 of flowable material of the type noted above.
  • the lower portion 21 is provided with a lid portion 26 for closing the container 24 and an upwardly extending member 28 of generally cylindrical or tubular configuration.
  • a fulcrum indicated by general numerical designation 29 and in the preferred embodiment of the present invention illustrated in FIGS. 5, 6 and 11, the fulcrum 29 is formed integrally with the lower portion 21.
  • the fulcrum 29 includes two generally triangularly shaped members 30-30 supported transversely by a cross member 31; the apexes of the triangular members 30-30 provide the fulcrum point for the lever 22.
  • the interior of the member 28 provides an outlet duct 32 and the upper portion of the member 28 is provided with a hollow, inverted, generally conical resilient member 34, best seen in cross-section in FIG. 6, mounted coaxially on top of the member 28 and extending upwardly and outwardly therefrom with the interior 35 of the conical resilient member in communication with the outlet duct 32.
  • the lever is provided with a forward arm 38 in turn provided with a spout 39 and the lever is further provided with a rearward arm 40 fulcrumed on the apexes of the triangular members 30-30 for angular movement in a plane normal to the lid portion 26 between sealing and dispensinc positions, as described in detail below, in which the forward arm 38 is moved toward and away from the lid portion 26 and in particular toward and away from the upwardly extending tubular member 28 and the conical resilient member 34.
  • the forward arm 38 is further provided with a downwardly extending generally cylindrically shaped member 42, FIG. 6, which depends downwardly from a surrounding flat surface 43, FIG. 6, provided on the underside of the forward arm 38.
  • FIGS. 5 and 6 which coaxially surrounds the cylindrical member 42 and is mounted on the underside of the forward arm 38 for movement with the cylindrical member 42 toward and away from the cylindrical member 28.
  • the interior of the tubular member 44 surrounding the exterior of the cylindrical member 42 provides an intake duct 45 in communication with the spout 39.
  • outlet duct 32, the interior 35 of the conical resilient member 34, the inlet duct 45 and the spout 39 cooperatively form a discharge path or passage, indicated by the arrows, from the interior to the exterior of the container 24 upon the lever 22 being in the dispensing position shown in FI G . 6.
  • the cylindrical or tubular members 28 and 44 are interconnected in a sliding, reciprocating, telescopic relationship with the interior of the lower portion of the tubular member 44 being provided with an inwardly extending annular projection 48 and with the exterior of the upper portion of the tubular member 28 provided with an outwardly extending annular projection 50; upon such sliding, reciprocating, telescopic movement, described in detail below, the annular projections 48 and 50 are in sliding interference engagement, respectively, with the exterior and interior of the respective tubular members and provide sliding seals between the tubular members preventing flowable material from escaping therebetween and unwantedly accumulating between the members and on the interior of the closure cap 20.
  • the forward arm 38 of the lever 22 is interconnected with the rear ward arm 40 of the lever by hinge or hinging structure indicated generally by numerical designation 54.
  • the hinge or hinging structure includes a centrally formed, semi-circular slot 56, FIGS. 5 and 7, extending between the forward and rearward arms of the lever 22 and in the direction of the rearward arm 40; in addition, the hinge or hinging structure 54 includes a pair of axially aligned sections or portions 58-58 of reduced wall thickness, shown in FIGS. 9 and 10, formed integrally between the rearward and forward arms of the lever 20 and extending outwardly, respectively, as shown in dashed outline in FIG. 7 between the ends of the semi-circular slot 56 and the edge of the disk-shaped lever 22.
  • the telescopically received tubular members 28 and 44 will not be bent or distorted and will remain in sealing engagement with the annular projections 48 and 50, described above, remaining in sliding, sealing engagement thereby preventing escape of the flowable material therebetween either during dispensing, as illustrated in FIG. 6, or during the acts of moving into the sealing and closing positions, with the closing position being indicated in FIG. 5.
  • Such translational relative movement has been found to provide an advance and improvement in the closure apparatus art and to prevent the unwanted escape of flowable material described above.
  • conical resilient member 34 is mounted coaxially on the upper portion of the tubular member 28 and extends generally upwardly and outwardly as shown in FIG. 6.
  • the conical resilient member 34 acts in cooperation with an outwardly extending annular projection 60 formed on the lower portion of the cylindrical member 42 to seal the closure cap when in disuse to provide the cylindrical member 42 with some inward flexibility, the interior thereof may be hollowed as shown in FIGS. 5 and 6 and the conical resilient member 34 may be formed of suitable flexible material more fully described below in the general description of the material of which the members of the closure apparatus of the present invention may be preferably formed.
  • the upper portion of the conical resilient member 34 will engage the flat under surface of the forward arm 38 surrounding the cylindrical member 42 and, as shown in FIG. 5, the conical resilient member will be compressed outwardly and downwardly and hence upon the annular projection 60 formed on the cylindrical member 42 being forced through the conical resilient member as shown in FIG. 5, the compressed conical resilient member 34 will provide and apply upwardly acting force acting upwardly against the forward arm 38 causing the annular projection 60 provided on the lower portion of the cylindrical member 42 to be forced into sealing engagement with the lower portion of the conical resilient member 34 thereby closing and sealing the above-described discharge passage.
  • annular projections 48 and 50 provided respectively on the tubular members 44 and 28 perform a dual purpose.
  • annular projections also provide the snap-fit between the lever 22 and the lower portion 21 of the closure cap 20 thereby providing means for assembly and prevention of easy disassembly of the two members when in the open position.
  • FIG. 12 there is shown an alternate embodi ment of the present invention which provides top rather than side dispensing.
  • structure corresponding to that identified in the earlier embodiment is given the same numerical designation and the embodiment of FIG. 12 in addition to providing the top dispensing through orifice or spout 39A in addition is also provided with a post or member 62 shaped for insertion into the orifice 39A and upon each closure of the apparatus, the post 62 cleans the orifice 39A.
  • closure cap of the present invention instead of being provided with threads for mounting and dismounting from a container may, if desired and if the economics involved permit, be formed integrally with a container; that is, the lower portion 21 of the closure apparatus may be formed integrally therewith with the lever member thereafter assembled thereto as described above or may be provided with suitable structure providing a snap-fit with the neck of the container.
  • the lower portion 21 and lever 22 of the closure of the present invention may be suitably formed by injection molding and may be preferably formed from a suitable plastic material material such as any one of several suitable polymers or copolymers known to those skilled in the art.
