  • FIGURE 11 is a bottom plan view of the cap of FIG- URE 10.
  • FIGURE 12 is a section substantially on line 1111 through FIGURE 10.
  • the novel cap .and valve actuator assembly 11 of the invention is mounted on a standard type pressurized dispenser container 12.
  • Container 12 comprises a rigid, usually sheet metal can body 13 closed at its top by a domed cover member 14 which has its periphery clenched tightly around the can body by a stiff formed bead 15.
  • cover member 14 is formed with a channel 16 inwardly of bead 15 with the outer periphery 17 of the channel being cylindrical and the inner periphery 18 of the channel formed with an outwardly projecting annular bead 19.
  • the lower end of the can body 13 is closed by 0 a bottom cover 21 clenched tightly thereupon by a bead such as that at 15.
  • the can body 13 and both top and bottom covers form a relatively stiff enclosure adapted to contain a mixture of liquid and vapor nnder considerable internal pressure.
  • valve control element 22 Upstanding from the center of domed upper cover 14 is a valve control element 22 which is reciprocable axially of body 13, spring biased upwardly in FIGURE 1, and formed with a discharge passage 23.
  • This valve control element 22 is of known construction and known manner of mounting wtihin the container, and a small depression of element 22 toward the interior of the container, downwardly in FIGURE 1, will result in opening a valve (not shown) inside the container to permit discharge of the container contents through passage 23.
  • This type of valve control element and the valve mechanism associated with it may be that disclosed in United States: Letters Patent No. 2,631,814 to which attention is directed for further detail.
  • valve contror element 22 is a nylon or like hollow cylindrical tube.
  • the cap assembly 11 consists essentially of only two parts, a cap 24 which may be an integral molded member of polyethylene or like relatively stiff but resilient plastic and an integral valve actuating member 25 which is axially reciprocably mounted on the cap 24.
  • Member 25 may also be a rigid molded part of light non-metallic plastic material.
  • Cap 24 has preferably a cylindrical side wall 26 that at its lower open end (FIGURE 12) is formed with a continuous deep recess 27 intersected by a plurality of, here four, short axial inner surface grooves 28.
  • An continuous internal shallow depression 29 is also formed in the cap wall near its open end, and in the assembly of FIGURE 1 this depression 29 is adapted to receive the can bead 19.
  • the foregoing recess and groove arrangement defines a flexible lip structure 31 on which depression 29 is located.
  • cap 24 When cap 24 is mounted upon the top of container 12 with its lower end in channel 16 the outer cylindrical surface 32 of the cap is backed by outer channel periphery 17, and the flexible lip structure 31 provides a snapon friction fit with the container cover. Any other suitable snap-on fit may be used between the lower open end of the cap and the container top.
  • Cap 24 is formed with a relatively thick top wall 33 preferably having an upwardly concave upper surface 34 (FIGURES 2, 5 and 12').
  • Wall 33 is interrupted by a diametrically extending slot 35 the side wall surfaces of which 36 are smooth and parallel to the longitudinal axis of the cap but are equally and oppositely inclined and symmetrically disposed on opposite sides of the cap axis.
  • slot 35 intersects the rear side of cap 24 in an axially extending opening 37 and, as shown in FiGURE 12, the front side of cap 24 in an axially extending opening 33.
  • the front side wall of the cap 24- is formed with a shallow fiat-bottomed recess 39 which is larger than opening 38, and parallel guide rails 41 are formed along the sides of opening 38 just inwardly of recess 39
  • a similar coextensive flat-bottom recess 40 is formed (FIGURE 12) in the inner surface of the front side wall of cap 12, and the lower edge of recess 46 forms an internal ledge 42.
  • the manually operable valve actuating member 25 is axially slidably mounted for free reciprocation in slot 35.
  • the opposite flat smooth side walls 43 converge symmetrically toward a substantially keystone shaped forward head 44 having opposite parallel side guide grooves 45 that interfit with guide rails 41 of the cap 24.
  • the lower end of head 44 has a downwardly open transverse groove 46 that fits slidably over the vertical guide lip 47 that extends along the lower edge of front opening 38.
  • a flat bottom surface 48 is formed on member 25 adapted to engage ledge 42.
  • the rear end of member 2 5 is an arcuate skirt 49 (FIGURES 4 and 9) that has a straight lower edge surface 59 adapted to rest on an internal wall ledge 51 formed by an internal wall recess 52 just below opening 37. Ledges 42 and 51 are at the same level. Skirt 49 is slidably guided by recess 52.
  • valve actuating member 25 is concave with the same curvature as. cap surface 34, and near the rear. side. a concave finger receiving depression 55 is formed, at the side opposite head 44.
  • a central hollow boss 56 depends from valve actuating member 25 and at its lower end boss 56 is formed with a socket 57 fitting snugly over the valve stem element 22 as shown in FIGURE 1 with the upper end of element 22 abutting the bottom of socket 57.
  • a through passage 58 is formed through valve actuating member 25, this passage, 58 extending upwardly from socket 57 where it aligns openly with valve stem passage 23. and then radially outwardly to terminate in a discharge mouth 59 in head 44.
  • a small bore nozzle plug 61 is mountedsin mouth 59.
  • the cap assembly 11. is made apart from the container.
  • the separately molded cap 24 and actuating member 25 are operatively'assembled by insertion of member 25 into slot 35.
  • the member 25 is freely axially slidably mounted between limits defined on the one hand by surfaces 48 and 50 abutting ledges 42 and 51 respectively, and on the other hand by beads 53 engaging the upper part of member 25.
  • cap assembly 11 To assemble the cap and container, the open end of cap assembly 11 is snapped into channel 16. This automatically aligns valve stem 22 to be received within socket 57, whereby the discharge passage will completely extend through member 25.
  • the relative dimensions of the parts are such that after stem 22 bottoms in socket 57 further axial movement of cap 24 to snap into the channel will lift free floating member 25 within the cap. Then when cap 24 is in final position in the container, the valve actuating member will be resting by gravity upon the valve stem 22, with its upper surface 54 substantially continuous with cap surface 34, and with its lower end well above ledges 42 and 51.
  • the slide mounting member 25 is sufiiciently frictionless, and the weight of member 25 so small compared to the spring bias of stem 22, that there is no depression of stem 22 and hence no discharge of the container contents as the cap assembly is placed on the container.
  • the operator merely points the head side 44 toward the area to be sprayed, and with his linger depresses member 25. Before member 25 hottoms on the cap ledges valve stem 22 will have moved suthciently to open the internal valve, and the container contents will discharge under pressure. It will be noted that since head 44 is located essentially outside the cap 24, the discharge from the mouth of passage 58 does not have to pass through any part of the cap. Release of member 25 by the operator restores the parts to original posltion.
  • cap 24 and member 25 are concave, they could be made fiat or in any other corresponding shape, a finger depression like that at 55 being in all embodiments.
  • the arrow-head shape of member 25 notifies the operator the spray direction immediately and no special indicia is needed.
  • the cap assembly of the invention comprises tWo molded components that are easily assembled, and mounting of the assembly on the container automatically locates the parts in position for immediate use.
  • the structure is simple and inexpensive, and reliable in operation, with only one moving part in the cap assembly.
  • said cap assembly comprising a hollow body open at its bottom and adapted to enclose the top of said container including said stem, a top wall and an annular side wall on said body, means providing an upwardly open slot extending entirely across said top wall and intersecting said side wall at upwardly open recesses in said side wall, means providing a removable snap-on fit for said body on said container and a rigid valve operating member slidably guided on said side wall at said recesses extending entirely across said top wall and reciprocably mounted on said body for free movement in said slot on the axis of said container and being accessible for actuating said valve stem without removing said cap assembly, said valve operating member being a separate member with respect to said body and resting in the assembly directly upon said valve stem but being of insuflicient weight to depress said valve stem, and said valve operating member having
