Definitions

  • the present invention relates to containers having dispensing devices carried in upwardly extending breast portions, and more particularly to such containers wherein substantially full size overcaps are held in snap-fit engagement with the breast portions to protect the dispensing devices when the containers are not in use.
  • the present invention provides an overcap which eliminates the objectionable features of the heretofore used overcaps.
  • An object of the invention is the provision, in'an aerosol can, of an overcap which not only protects the valve mechanism, but in addition greatly enhances the appearance of the can and provides a broad fiat stacking surface which permits the stacking of one can upon another.
  • Another object is the provision of an overcap having an inwardly curled bead which is snapped beneath an outwardly projecting shoulder in the breast of the can to securely hold the overcap against inadvertent displacement.
  • Yet another object is the provision of such a container and overcap construction wherein the interengaging parts may be die formed to insure uniformity of dimension, and thus of fit.
  • Still another object is to provide a snap-on overcap for a double seamed can which does not require mutilation of the top end seam, and the consequent danger of leakage therethrough, for its assembly to the can.
  • FIGURE 1 is a perspective view of a container embodying the principles of the instant invention
  • FIG. 2 is an enlarged fragmentary sectional view taken substantially along the line 2-2 in FIG. 1, parts being broken away;
  • FIG. 3 is a plan view of a can embodying a slightly modified form of the invention, the can being illustrated with its overcap removed;
  • FIG. 4 is an enlarged fragmentary sectional view, sim- "ice ilar to FIG. 2, but taken in a vertical plane through one of the spaced shoulder sections formed in the breast portion of the can as illustrated in FIG. 3, parts being broken away; and
  • FIG. 5 is a fragmentary view in side elevation of two stacked cans made according to the principles of the instant invention, parts being shown in section, other parts being shown in dotted lines, and still other parts being broken away.
  • the drawing illustrates a container comprising a cylindrical body 12 preferably formed of a. single sheet of metal having its longitudinal marginal portions secured in a suitable side seam (not shown).
  • the lower end or" the body 12 is closed by means of a substantially flat bottom closure 14 which is secured to the body in a conventional double seam 16.
  • the upper end of the body 12 is closed by a top end member 18 which has its marginal peripheral portion interlocked with the upper marginal end portion of the body 12 to form a conventional hermetic double seam 20.
  • the upper end member 18 extends inwardly from the bottom of the vertical countersink wall 22 of the double seam and is curved upwardly and formed into an upwardly extending upstanding breast 24 which projects a substantial distance above the top double seam 20 (see FIGS. 2 and 5).
  • cal configuration while its lower portion comprises a gently curved annular wall 26 which forms the base of the breast 24 and is closely spaced inwardly of the top.
  • FIG. 2 for a purpose which will be hereinafter explained.
  • the frusto-conical breast portion terminates in a centrally disposed mouth or opening into which is clinched a cup-shaped fitting 31 which carries a dispensing valve 32 having a dispensing orifice 34 provided therein (see FIG. 5).
  • the dispensing valve 32 may be of any conventional type. As a rule, such valves are designed to bring the dispensing orifice 34 into communication with the interior of the container to dispense the product therefrom when lateral or downward pressure is exerted against the valve 32. In order to prevent the inadvertent application of such pressure during shipment, storage and merchandising of the filled container, and to permit the stable stacking of like containers one upon the other, a cylindrical overcap 36 is provided which completely encloses the container breast 24 and dispensing valve 32.
  • This overcap 36 is preferably formed from a drawnone-piece metal blank and is formed with an annular depending side wall or skirt 3'8 and a flat top wall 40.
  • the lower end of the annular side wall '38 of the overcap 36 is rolled inwardly to provide an inwardly projecting curl or bead 42 which snaps over the shoulder into groove 37 on breast 24 Within the annular space 28 in close engagement with the upper and lower outwardly extending surfaces of groove 37 beneath the shoulder. Due to the inherent resiliency of the material from which the overcap 36 is made, the inward curl 42 may be yieldably snapped into groove 37 beneath the shoulder 30 and also easily snapped in a reverse direction upwardly over the shoulder 30 to remove the overcap from the container 10 to uncover the valve 32 and permit dispensing
  • the upper portion 25 of the, breast 24 is substantially of dome shaped or frusto-coni-l of the container contents. As seen in FIGS.
  • the outside diameter of the side wall or skirt 38 is less than the inside diameter of countersink wall 22, whereby the cylindrical annular side wall 38 of the overcap 36 is spaced slightly inwardly from the vertical countersink wall.
  • sufiicient clearance is provided to permit outward distension or flexing of the cap curl and skirt during manual positioning of the cap on or removal of the cap from the breast 24 by snapping the cap over the shoulder 30. from one sixteenth to one quarter of an inch, but these figures are not to be considered as limitations upon the inventive concept.
  • the overcap top wall 40 and skirt 3% are spaced from and free of engagement with any portion of the container 10, the sole engagement between overcap 36 and container constituting the frictional engagement of curl 42 with groove 37.
  • the locking shoulder 30 preferably is formed by die action. Since it is not incorporated in the double seam 20, it is not disturbed by the double seaming operation. Thus, its dimensions can be accurately maintained regardless of variations in the seaming action of the closing machine which forms the double seam 20.
  • the curled bead 42 of the overcap 36 is also preferably die formed, thus insuring accuracy of dimension so that the desired snapfit engagement between these parts can be consistently maintained in large scale commercial production.
  • the overcap 3'6 completely conceals the breast 24 and valve 32, thus giving a pleasing appearance to the container.
  • the flat top wall 40 of the overcap is of sufiicient diameter to provide a broad stacking surface when in stacking engagement with the flat panel of the bottom closure 14 of a like container, as seen in FIG. 5.
  • FIGURES 3 and 4 illustrate a modified form of the invention wherein the locking shoulder of the breast 24 is not continuous but is rather a discontinuous or interrupted shoulder comprising three circumferentially spaced shoulder portions 44 which project laterally outwardly from the bottom of the breast adjacent the top of the curved base wall 26 and cooperate to define the grooves 37 having the same yieldable locking action as does the groove 37 beneath the continuous annular shoulder 30 of FIG. 2.
  • the word shoulder includes both forms and all equivalents thereof.
  • a dispensing container having a dispensing opening and a protective overcap therefor, comprising a container body having a top end, said top end including a peripheral vertical countersink wall inwardly of the container body, said countersink wall at its lowermost end extending laterally inwardly and merging with an upwardly curved annular base wall of a central upstanding frustoconical breast to define an annular countersunk channel between said base Wall and said countersink wall, said breast terminating at its upper end in a dispensing opening, said overcap having a top wall and a cylindrical skirt depending therefrom, said skirt terminating at its lower end in an inwardly extending curl, means for confining said curl and the adjacent lower skirt end within said countersunk channel to prevent accidental dislodgement of said overcap from said container, said means comprising a shoulder formed on said breast above said curved base wall and disposed within said countersunk channel, said shoulder and the adjacent portion of said base wall defining therebetween an outwardly facing groove spaced above the bottom
