Definitions

  • the second disadvantage is the difficulty in intentionallyopening many typical safety closures, the most common of which is various varieties of palm and twist" types. This has been found to be true when such closures are attempted to be opened by older or unedu gated persons, particularly if they are handicapped or, for example, suffering from arthritis. It is for these and other reasons that the Foodand Drug Administration lists among its. requirements for safety closures not only criteria for precluding the accidental removal of a closure from an associated container, but criteria for the relatively easy removal of safety closures when such removal is intentionally desired.
  • a safety closure which includes an end panel and a depending peripheral skirt adapted for telescopic unification with an associated container body, the peripheral skirt including means cooperative with the container body for normally interlockingly securing the same to each other, and means for temporarily radially relatively deflecting the peripheral skirt to disengage the cooperative interlocking means whereby the closure can be removed from the container body.
  • a further object of this invention is to provide a novel closure of the type immediately heretofore set forth wherein the peripheral skirt is constructed from material having a slow resilient return rate whereby removal of the closure from the container body can take place during such time as is required for the peripheral skirt to return to its normal non-deflected interlocked condition.
  • FIG. 6 is a perspective view of another container and safety closure constructed in accordance with this invention with a portion thereof broken away and removed for clarity, and illustrates a head of the closure peripheral skirt in interlocked relationship with an associated groove of the containerbody above a recess shoulder of the container body.
  • FIG. 7 is an enlarged bottom plan view of the safety closure of FIG. 6 with a portion thereof removed for clarity, and illustrates a plurality of circumferentially spaced reinforcing lugs on the interior of the closure peripheral skirt.
  • FIG. 8 is an enlarged fragmentary sectional view of the encircled portion of FIG. 6, and more clearly illustrates the interlocked condition of the closure and container.
  • FIG. 9 is a fragmentary sectional view of the container and closure of FIG. 8, and illustrates the manner in which an axial force is applied to the closure to deflect the peripheral skirt thereof radially outwardly to disengage the cooperative interlocking means incident to the removal of the closure from the container.
  • FIG. 10 is a fragmentary sectional view of another container and safety closure constructed in accordance with this invention, and illustrates a gasket constructed from foam or like compressible material disposed in a channel of the closure.
  • FIGS. 1 through 3 of the drawings A novel container and safety closure combination constructed in accordance with this invention is illustrated in FIGS. 1 through 3 of the drawings, and is generally designated by the reference numeral 10.
  • the combination includes a container 11 and a closure 12 which are normally united in interlocked relationship in the manner best illustrated in FIG. 2 of the drawing.
  • the closure 12 is preferably constructed from polymeric or copolymeric plastic material by conventional injection molding techniques, and the material thereof though it is resilient has a very slow resilient return rate. Stated another way, when the material of the closure 12 is strained within its elastic limit from its original position, it will not immediately rebound or snap to its original condition but will instead slowly return with the rate of return being a function of time between the deflected and normal condition of the closure. With this characteristic of the material of the closure 12, the latter is intentionally removed from the container 11 by applying an axial downward force against the closure 12, as indicated by the solid unnumbered arrow in FIG.
  • annular sealing member 39 also functions as a spring which in the normal position (FIG. 2) continuously applies a biasing force in a direction tending to lift the closure 12 upwardly away from the lip 16 thereby maintaining the shoulders 22, 31 in intimate interlock relationship.
  • This closing force created by the annular seal 39 can similarly be regulated by varying the resilience of the material as well as the cross-sectional thickness of the sealing member 39 to thereby selectively alter the closure to vary the forces required to temporarily distort the peripheral skirt 27 to its deflected condition (FIG. 3).
  • FIGS. 6 through 9 of the drawings Another novel containerand safety closure combination constructed in accordance with this invention is illustrated in FIGS. 6 through 9 of the drawings, and is generally designated by the reference numeral 40.
  • the combination 40 includes a container 41 and a closure 42 which are normally united in interlocked relationship in the manner best illustrated in FIGS. 6 and 8 of thedrawings.
  • the container 41 includes a generally cylindrical body .43 closed at one end by a bottom wall (not shown), while an opposite end portion 44 is normally open and includes an inner cylindrical surface 45, an
  • the closure 42 may be removed from the container 41.
  • the precise rate of return from the strained condition (FIG. 9) to the normal condition (FIG. 8) once the bead 60 is above the shoulder 59 may be varied, as desired, by specifically compounding the material to vary the creep characteristics thereof.
  • the peripheral skirt 58 thereof is provided at its interior with a plurality of circumferentially spaced projections 63 which bottom against the surface portion 50, as shown in FIG. 9. s
  • FIG. 10 illustrates another combined container and safety closure combination constructed in accordance with this invention, which is generally designated by the reference numeral with the remaining components thereof which are identical to the combination 40 being primed.
  • the combination 70 differs from the combination 40 in that the shoulder 59 has been eliminated and as gasket 71 constructed from plastic foam or like easily compressible material is housed in a downwardly opening channel 72 between the peripheral skirt 58' and the sealing member 57'.
  • the gasket 71 would not, however, hinder the functional characteristics of the closure 70 which are identical to those of the closures 12, 12', 42, and would simply function in lieu of the fin 39 of the closure 12 in addition to performing its normal scaling function.
  • a combined container and closure combination comprising a container body having a normally open end portion, a closure body closing said normally open end portion, said closure body having a peripheral skirt in telescopic relationship to said body end portion, cooperative means between said body end portion and said peripheral skirt for normally interlockingly securing said container and closure to each other, means for temporarily radially relatively deflecting said body end portion and said peripheral skirt to disengage said cooperative interlocking means whereby said closure can be removed from said body end portion, and said deflecting means is in part defined by constructing at least one of said peripheral skirt and said body end portion from material having a slow resilient return rate whereby removal of said closure from said body end portion may take place during such time as is required for said peripheral skirt and body end portion to return to the normal nondeflected interlocked condition thereof.
