  • FIG. 3 is a sectional elevational view taken generally along the line 3-3 of FIG. 1, illustrating the protective cap thereof in operative association with an aerosol can.
  • FIG. 4 is a sectional elevational view similar to FIG. 3, but illustrating a protective cap of the present invention in operative association with a bottle.
  • FIG. 5 is a perspective view illustrating the preferred mode of manual operation of the instant device.
  • a protective cap is there generally designated 10, and may advantageously be integrally fabricated of suitable material, say plastic, as by molding or other suitable means.
  • the cap may include a generally cylindrical side or outer wall 11 having its lower end open and there terminating in a generally circular inner end edge 12.
  • the upper or outer end of cylindrical wall 11 may be closed, as by a generally fiat cap top or circular top wall 13.
  • the cap top 13 Spaced radially inwardly from the cylindrical sidewall 11, the cap top 13 is provided on its inner or underside with a pair of generally semicircular or arcuate depending inner walls 15, being generally concentric with respect to the sidewall 11 and cap top 13, and being spaced to define slits or slots, as at 16, between adjacent ends of the arcuate inner walls or segments 15.
  • an inturned lip or ledge 17 Provided on the lower or inner end of each arcuate wall I5 is an inturned lip or ledge 17, the corners 17a of which may be beveled to facilitate removal of the cap best seen in FIGS. 2 and 3.
  • each arcuate depending inner wall 15 and its associated lip or ledge 17 may be considered as a retainer or jaw, so that there are at least a pair of facing spaced retainers or jaws l5, 17 located in an array generally coaxial with the outer wall I l.
  • Upstanding from or projecting exteriorly on the cap top or end wall 13 are a pair of upstanding, arcuate wall membersor lugs 18, each being generally semicircular in configuration and located in alignment with a respective arcuate inner wall member 15.
  • the upstanding members 18 define a generally circular array coaxially aligned with the array of jaws l5, l7 and having slits or slots therebetween, as at 19. each in respective alignment with the slits or slots 16.
  • each jaw l5, l7 and its associated upstanding member or lug 18 is relatively great, as compared to the wall thickness or section of the cap top 13.
  • These thicknesses or sections are selected to afford a desired degree of resilient flexibility to the cap top 13, and a desired degree of relative rigidity between each jaw I5, 17 and its aligned upstanding member or lug 18.
  • other suitable means of effecting this desired relative rigidity between wall portions 15 and 18, and resilient flexibility of cap top wall 13 may be employed, if desired.
  • the selection of wall sections or other suitable design results in resilient flexure of the cap top 13 to effect swinging displacement of the jaws l5, 17 toward and away from each other upon respective swinging displacement of the lugs 18 away from and toward each other.
  • the lugs are displaced toward each other, while the jaws l5, 17 are displaced away from each other in the directions of arrows 21.
  • the protective cap 10 is illustrated in operative association with an aerosol container or can, which may be generally designated 25.
  • the can 25 may be conventional, and may be described as including a cylindrical sidewall 26, an end wall 27 on one end of the cylindrical sidewall 26, being joined thereto by a circumferentially extending bead 28.
  • the end wall 27 is provided with an outstanding reduced portion or neck 28 having formed thereon an enlargement, collar or head 29.
  • the manually actuable dispenser valve 30 Centrally within the enlargement, head or collar 29 may be provided the manually actuable dispenser valve 30, all of which is generally conventional.
  • the skirt 11 may have its inner end or edge in abutting engagement with the end 27 of the can or engaging the bead 32.
  • the jaws l5, 17 are circumposed in their circular array about the reduced or necked or portion 28, having their lips or ledges l7 engaged beneath spaced locations of the enlarged head or collar 29.
  • the jaws l5, l7 retain the protective cap 10 on the aerosol container 25, while the inner end or edge 12 of the wall 11 limits movement of the protective cap toward the can.
  • the protective cap is thus effectively retained in position on the can protectively covering, obscuring and preventing access to the valve 30.
  • the protective cap 10 may be freely rotated in the above-described condition on the can 25, it may not be removed or otherwise dislodged to afford access to the valve 30, except by the deliberate manual actuation shown in FIG. 5.
  • the protective cap la may be essentially similar to the protective cap 10, being shown only of different proportions.
  • the protective cap a includes a generally cylindrical outer sidewall lla having its lower end open and terminating in a lower end edge 12a, the upper end being closed by a generally flat, circular closure wall or cap top 13a.
  • arcuate jaws 15a Depending internally from the cap top 13a are a plurality of annularly arranged, arcuate jaws 15a, and upstanding from the exterior of the cap top 130 are a plurality of annularly arranged arcuate actuation members or upstanding lugs 18a.
  • the sections or thicknesses of these members are related so as to insure relative rigidity between each jaw 15a and its associated, aligned upstanding member 18a, while also assuring resilient flexibility of the cap top 13a. in the manner described in connection with protective cap 10.
  • the protective cap 10a is associated in its protective relation with a bottle-type container a wherein one end wall 27a is provided with an outlet neck 28a having an end enlargement, bead or collar 29a.
