Definitions

  • This invention has particular application to eyedropper cap-container combinations for protecting the bulb and for precluding or making more difficult the unauthorized opening of the container by a young child.
  • the invention may also find application in other containers not including an eye-dropper cap as will be apparent from the following description.
  • FIG. 1 is a part sectional view of a cap-container combination according to the invention
  • FIG. 3 is a sectional view of the line 33 of FIG. 1;
  • FIG. 4 is an enlarged detail of FIG. 1;
  • FIG. 5 is a detail of an alternate form of overcap.
  • FIGS. I to 4 of the drawings there is illustrated a container with a shoulder portion 12 from which a neck portion I4 projects.
  • the neck portion 14 has an external screw thread, and on which, to close the container, is secured an eye-dropper cap 16 of largely conventional form comprising a generally rigid cylindrical skirt portion 20 which has internal screw threads configurations 22 for cooperation with the screw thread configurations of neck 14 of the container and an internally directed flange 24 at its upper edge which is re ceived in an annular groove 26 of a flexible bulb 28 to retain the bulb on the skirt.
  • a glass or other material applicator tube or dispenser tube 30 is secured in the lower edges of bulb 28 by any convenient means, not shown in the drawings, but which may for example comprise an outwardly turned annular flange on the upper edge of the tube seated within a corresponding groove of the material of the bulb.
  • the cap-container combination is largely conventional.
  • a measure of that liquid may be drawn into the tube by squeezing bulb 28 and then releasing it. Thereafter the eye-dropper cap may be taken to whatever site is desired and the application of pressure to the bulb will cause the liquid contained therein to be ejected.
  • This structure is well known per se.
  • An overcap generally indicated at 40 is located over the cap 16 and comprises a resilient skirt 42 which covers cap skirt 20 and a dome 44 which extends over bulb 28.
  • the dome 44 and resilient skirt 42 are connected by an annular shoulder region 46 which is supported on the upper edge of the cap 16.
  • FIG. 4 The lower edge region of the resilient skirt 42 and the adjacent lower edge region of the cap 20 are illustrated in cross section in FIG. 4.
  • an internally projecting bead 48 is formed on the 5 interior of the resilient skirt to constitute latching means which cooperates with downwardly facing sur face 50 defining the lower edge of the skirt of the first or eye-dropper cap 16.
  • FIG. 3 Specific reference is made to FIG. 3 from which it will be seen that the bead 48 is of generally chordal configuration and that there are two such elements disposed diametrically apart on the lower region of the interior surface of the overcap.
  • the outline of the resilient skirt of the overcap is of generally oval form having a major axis Mj and a minor axis Mn.
  • the projections 48 are disposed on the minor axis and between the interior surface of the overcap and the cylindrical outer surface of cap 16 at the major axis there is a clearance C.
  • the clearance C is such as to accommodate flexure of the overcap by the application of pressure to the regions thereof on the major axis so that the overcap tends to widen along its minor axis and free the projections 48 from the surface 50 of cap 20 so that the overcap may be removed axially from cap 20 and therefore allow the cap 16 to be removed from the container in conventional fashion.
  • FIG. 5 of the drawings is largely similar to that of FIGS. 1 through 4 except that the skirt of the overlap is slotted directly above the beads 48 as at 60 so that the bead may be made substantially without introducing mold removal problems as could be the case if the slots were not provided.
  • the skirt portion of the overcap may be of cylindrical form of greater internal diameter than the exterior diameter of the skirt of the eye-dropper cap as to leave a clearance C such that would accommodate flexure of the skirt of the overcap to release the latching means and allow the overcap to be removed.
  • said first cap comprises a dispensing tube depending therefrom and a compressible bulb projecting from an upper surface thereof, said overcap comprising a dome extending over said bulb portion of said first cap.
  • a container and closure combination comprising a container with a threaded neck, a first cap having a correspondingly threaded cylindrical skirt engaged on said neck to close the container, said first cap comprising a flexible bulb and a dispenser tube communicating with the bulb and extending into the container and an overcap having a resilient skirt covering the skirt of said first cap and a dome covering said bulb to prevent operation of the bulb and the removal of the first cap from the container without first removing the overcap, said resilient skirt having a lower portion of generally oval section having a major and a minor axis, said minor axis being of greater length than a diameter of an outer surface of said cylindrical skirt of said first cap whereby said overcap is freely rotatable upon the first cap, an internal latching surface on said resilient skirt at an end region of a minor axis thereof, a downwardly disposed latching surface on said first cap engaged by said latching surface of said resilient skirt to preclude the axial removal of said overcap from said first cap without first disengaging said latching surfaces, said resilient skirt being compressible
  • said internal latching surface of said overcap is defined by a chordal projection on a lower portion of said resilient skirt, said projection engaging a lower edge region of said first cap.
