Definitions

  • ABSTRACT This disclosure relates to a novelty safety closure comprising a fitment and a cap for assembly together and telescopic press application onto a container finish, the cap having means reinforcing .a part of the fitment against outward deflection, the fitment having an interior surface reducing in diameter from a leading surface portion thereof toward the opposite end thereof, the leading surface portion in the area of the reinforcing means having a diameter sufficient to permit telescopic assembly of the cap and fitment on an associated container finish with little initial resistance to the relative telescopic movement of the diminishing diameter of the fitment above said surface portion with thereafter increasing resistance to a point of interference which is offset by radial outward deflection of the fitment above said surface, portion, and the fitment terminates at the opposite end thereof in means for axially opposing abutment of an associated container finish thereby precluding unauthorized removal of the fitment and/or cap from a container finish.
  • the finish also includes means for axially opposing abutment of the fitment abutment means, and in.a preferred embodiment of the invention the finish and fitment abutment means are opposed annular shoulders,
  • Safety closures have recently come into prominence because of the desirablility of federal, state and local agencies to preclude or substantially reduce accidental illness and/or death resulting from the consumption of packaged products.
  • a most notable example is that of infants or younger children opening aspirin bottles and consuming the contents thinking it to be candy.
  • a safety closure which comprises a fitment and a cap assembled together by relative telescopic press application, the cap having means reinforcing a part of the fitment against outward deflection, the fitment having an interior surface reducing in diameter from a leading surface portion thereof toward the opposite end thereof and the leading surface portion in the area of the reinforcing means having a diameter sufficient to permit telescopic assembly of the cap and fitment on an associated container finish with little initial resistance to the relative telescopic movement and the diminishing diameter of the fitment above the surface portion thereafter increasing the resistance of telescopic assembly to a point of interference which is offset by radial outward deflection of the fitment above the surface portion thereby achieving rapid assembly ofthe components upon a container finish, and the fitment further including means at the opposite end thereof for axially oppos ing abutment of an associated container finish thereby precluding unauthorized removal of the fitment and/or cap from a container finish by persons when initiated in the operation of the closure.
  • Still another object of this invention is to provide a novel closure of the type set forth wherein the closure is secured to threads of the fitment by lugs of the peripheral skirt, and the lugs constitute at least in part said reinforcing means.
  • Another object of this invention is to provide novel safety closure of the type heretofore defined in combination with a novel container finish having means between the finish and inner peripheral fitment surface for spacing a major portion of the latter away from the finish thereby allowing a simple presson of the cap and fitment assembly to the associated container and to provide reduced frictional purchase to permit rotation of the fitment and closure in unison.
  • FIG. 1 is a fragmentary side elevational view with portions broken away and shown in section for clarity, and illustrates a fitment and a container-finish with the pre-assembled closure being removed from the fitment to gain access to a product within the container.
  • FIG. 2 is an enlarged sectional view of the fitment, closure and container of FIG. 1 taken along line l1 thereof, and illustrates a pair of annular abutment means in axially opposed spaced relationship in the form of a bead and shoulder of the container finish between which is sandwiched the fitment-carrying the closure.
  • FIG. 3 is a fragmentary side elevational view again with portions broken away and shown in section for clarity, and illustrates a fitment, a container and a separable container finish with the pro-assembled closure being removed from the fitment to gain access to a product within the container.
  • FIG. 41 is an enlarged sectional view of the fitment, closure, container finish and container of FIG. 3 taken along line 33 thereof, and illustrates the container finish having a bead interlocked with a groove of the fitment for maintaining the components in slip-fit assembled relationship.
  • a novel safety closure constructed in accordance with this invention is generally designated by the reference numeral 10, and includes a closure or cap I1 and a fitment l2 therefor. When united or pre-assembled in a manner to be described more fully hereinafter the safety closure is assembled upon a container 13.
  • the closure 10 is of a conventional construction and includes an end panel 14, a depending peripheral skirt 15, and an inwardly upwardly and downwardly directed curl or bead 16 which is interrupted to define three locking lugs 17 of which only one is illustrated in the drawing.
  • the locking lugs 17 are disposed equally about the periphery of the cap 11.
  • the cap 11 is preferably constructed from metallic material and sealing compound 18 (FIG. 2) may be applied to the interior in a conventional manner if the contents of the container 13 are liquid. Otherwise the sealing compound 18 may be eliminated, if found necessary or desirable, or substituted for with paper liner material.
  • the fitment 12 is preferably constructed from resilient polymeric or copolymeric material, such as polyethylene, and includes a generally annular body20 having axially opposite open ends 21, 22 between which are respective inner and outer peripheral surfaces 23, 24, respectively, the former being a generally frusto conical lead surface which cooperates with the container 13 during assembly in a manner to be described hereinafter.
  • the fitment I2 additionally includes three equally spaced threads 26 (FIG. 1) which each cooperates with one of the lugs 17 for securingthe closure 11 upon the fitment 12 upon the preassembly thereof prior to being capped upon the container 13.
  • Each lug 17 rides beneath its associated thread 26 and is drawn or cammed downwardly by an inclined lead wall 27 which levels out at 28 and terminates at an outwardly directed rib or stop 30.
  • the body 20 of the fitment 12 terminates adjacent the end 22 in an axially downwardly facing terminal wall 31 and a'depending peripheral skirt 32 whose outer peripheral surface includes vertical ribs 33 and whose bottom includes a plurality of projections-34 which function to facilitate the assembly of the closure 11 upon the fitment 12, as will be described more fully hereinafter.
  • An opening 35 is formed beneath each thread 26 in a conventional manner during the injection molding of the fitment 12.
  • the container or bottle 13 includes a lower bead 36 which merges with a frusto-conical wall 37 (FIG. 2) of a container neck or finish 38. Above the frusto-conical wall 36 is another annular bead 39 having an axially downwardly facing wall 40 opposingthe wall 25 of the fitment 12.
  • the finish 36 terminates in an upper annular face or surface 41 which is slightly above the wall 25 of the fitment 12 when the elements are in assembled relationship, as indicated best in FIG. 2, it being noted that only the finish 38 and adjacent elements 39, 41 is embedded in the sealing compound 18 of the cap 11.
  • the closure 11 and fitment 12 are assembled by first moving the same axially relative to each other such that each lug 17 becomes positioned adjacent its associated thread 26 with the curl 16 resting atop the uppermost surface (unnumbered) of the radial wall (also unnumbered) between the peripheral skirt 32 and the body wall 20 of the fitment l2. Thereafter, the closure 11 and the fitment 12 are rotated relative to each other at which time the lugs 17 ride along the inclined lead walls 27 and the succeeding walls 28 until each lug 17 contacts a stop 30.
  • the ribs 33 and teeth or projections 34 serve as gripping surfaces for a chuck or similar holder to prevent the fitment 12 from rotating upon the rotation of the closure 11.
  • the packager simply telescopes the pre-assembled closure 11 and fitment l2 downwardly upon the finish until the fitment 12 seats in sandwiched relationship between the frusto-conical wall 37 and the annular wall 40 of the container finish 38, in the manner best illustrated in FIG. 2.
  • a definite relationship has been established between what has been heretofore termed the frusto-conical lead surface 23 of the fitment 12, the external diameter of the finish bead 39, and the relative position of the lugs 17 relative to the bead 39 during the assembly operation.
  • a line L1 designates a development of the maximum diameter of the finish bead 39.
  • the line L2 which is normal to the line L1 is shown intersecting the latter at a point P1 at which the inner diameter of'the surface 23 corresponds to the maximum diameter of the bead 39. It will be noted that the line L2 is also above each lug 17.
  • the fitment is initially positioned with its pre-assembled closure 11 upon the finish 38 of the container 13 there is little or no resistance since the diameter of the leading surface 23 below the line L2 is larger than the diameter of the bead 39 thus movement of the pre-assembled closure 11 and fitment 12 to the final position shown in FIG. 2 is virtually accomplished in the absence of initial resistance by the fitment 12'of the closure 11.
  • the bead 39 is adjacent the most rigid area of the pre-assembled unit since the area immediately below the line L2 is reinforced against outward deflection by the thicker material of the fitment 12 in the area of the threads 26, and the reinforcement offered against deflection of the fitment 12 by the lug l7 and the associated curl 16 of the cap 12.
  • This area is, however, virtually passed with little resistance as the bead 39 approaches point P1 and passes the same.
  • this passage resistance is lessened since lesser reinforcement'of the fitment l2 occurs above the line L2 than below the same. Accordingly, the upper portion of the body 20 above the line L2 will deflect radially outwardly as the finish bead 39 is guided toward and beyond terminal wall 25 by the leading surface 23.
  • the closure of this invention is designed specifically to achieve a seal when the package contents are liquids or hygroscopic solid substances harmful to human beings.
  • An effective seal is achieved upon assembling the filled container 13, the closure 11 and fitment l2 primarily because only the container finish is embedded in the sealing compound 18, as opposed to the seal achieved with respect to FIG. 4, as will be described further hereinafter.
  • seepage and/or slippage is precluded until such time as intentional opening of the closure takes place.
  • the diameter of the bead 39 will temporarily cause the fitment 12 and particularly the body thereof to flex radially outwardly above the line L2 during assembly as was heretofore described but upon the bead 39 reaching the seating thereof above the wall the fitment 12 will assume its nonstressed condition at which design tolerances permit the fitment 12 to rotate relatively free with respect to the container 13.
  • a gap G is formed between the exterior surface of the finish 38 of the container 13 and the inner lead surface 23 of the fitment 12 due to the manner in which the inmost edge (unnumbered) of the wall 31 bears on the frustoconical wall 37 (FIG.
  • the wall 37 prevents the body 20 from moving inwardly and thus reduces frictional purchase between the fitment and the finish to create'a looseness for additionally permitting unitized rotation of the cap 11 and fitment 12.
  • the wall 37 also continually urges the fitment 12 upwardly and maintains abutment between the walls 40 and 25.
  • FIG. 4 Another container, fitment and closure is illustrated in FIG. 4 and like primed reference numerals have been applied thereto to indicate elements identical to those of the combination 10 of FIGS. 1 and 2. The differences between the structure of FIGS. 3 and 4 and that of the structure of FIGS.
  • 1 and 2 is (a) the inclusion on the inner surface 23 of the fitment 12 of a groove 45 which receives the bead 39 of the finish 38'; (b) the provision of an integral end panel 46 in the finish 38 which is provided with an axial dispensing aperture 417 and (c) the formation of the container finish 38' as an element separate and apart from a container body 47 which is constructed from metallic material and has double seamed at 18 thereto an annular closure 49 terminating in a flange 50 to which is snap-secured a lower end portion 51 of the container finish 38'.
  • the structure at elements 46 through 51 is self-evidentand details of the groove 45, the bead 39 and the sealing compound 18' associated with the closure 11 will be found more specifically detailed in commonly assigned application Ser. No. 260,105, filed June 6, 1972 in the name of Frank H. Lecinski, Jr. and now US. Pat. No. 3,836,034.
