Definitions

  • An advantage of one-piece actuators is the lower cost, since there are fewer pieces and simpler assemblies.
  • Some prior one-piece actuators utilize a hinge connection between the movable button-nozzle and the cap body. Such a connection greatly restricts the extent of movement of the button, and also requires the little movement which is possible to be of an arcuate character, different from the linear movement of valve stems or piston plungers. Accommodation is thus necessary, resulting in difficulty at times.
  • Objects of the present invention are: to provide an improved one-piece plastic guard-type actuator which may be produced in simple molds, and which enables the button to have so great a travel that it is readily usable with a pump-type dispenser; to provide an actuator as above, where the button portion can move wholly in a straight line, and an actuator having a guarded or protected spray and which is rugged, reliable and not likely to crack, break or fail; to provide an actuator as characterized, which is extremely simple, easy and economical to mold; small, compact, easy to operate, of attractive appearance, and capable of production with either a large (jumbo) overall diameter in a double-skirt construction, or smaller overall diameters involving single skirt constructions.
  • FIG. 1 is an axial sectional view of an improved onepiece guard-type actuator cap and spray button as provided by the invention, shown mounted on the upper portion of a pressurized container.
  • FIG. 2 is a view like that of FIG. 1, but showing the actuator with the button depressed or in the discharging position.
  • FIG. 3 is a top plan view of the one-piece actuator cap of FIGS. 1 and 2.
  • FIG. 4 is a front elevational view of the actuator cap of FIGS. 1 and 2.
  • FIG. 5 is a fragmentary view, taken on the line 55 of FIG. 3, with the depress button being held down.
  • FIG. 6 is an axial sectional view of a single-mounting skirt-type actuator, carried by a pumping type dispenser.
  • FIG. 7 is a top plan view of an actuator constituting another embodiment of the invention.
  • FIG. 8 is a top plan view of an actuator constituting still another embodiment of the invention.
  • the cap is of the double-skirt type, although it should be understood that the larger or outer skirt is not essential to the functioning of the depress button or the mounting of the same, and the guarding against inadvertent operation.
  • the outer skirt 18 is shown as being generally cylindrical and concentric with an inner skirt 20.
  • the inner skirt 20 has an internal detent bead 22 engaged with the undersurface of the crimped closure shoulder 14, in the usual manner.
  • the outer skirt 18 engages the outer edge 12 of the can 10, and may add stability to the mounting of the cap.
  • a depress button 24 is provided and so connected to the inner skirt 20 as to enable a considerable, quite free and easy vertical straight line movement of the button to be effected, as may be seen from a comparison of FIGS. 1 and 2 showing respectively the non-depressed and depressed positions of the button.
  • the connector means between the button 24 and the inner skirt 20 is such as to enable onepiece fabrication of the cap with relatively simple molds, in a quick and economical manner.
  • the depress button 24 is connected to the cap body by a plurality of thin, resilient connector strips of relatively great length, there being illustrated a substantially U-shaped inner connector strip 28, and a substantially U-shaped outer connector strip 26, said U-shaped strips having their ends joined by short yoke portions 30.
  • the connector strips 26, 28 are also connected to each other by additional short webs 32.
  • the depress button 24 is connected to the inner U-shaped connector strip 28 at three points, by short webs 34.
  • the outer U-shaped connector strip 28 is connected to the inner skirt 20 of the cap body by three short connector webs 36. It will be seen that the short connector webs 36 and 34 are paired with each other, and that the short connector webs 32 are located substantially midway between the pairs 32, 36, so that the short webs are in a staggered pattern.
  • the cap body may comprise, in addition to the outer and inner skirts 18, 20, a substantially annular or continuous top connector wall or bridge 38 which as the front portion of the cap body makes a distinct dip, resulting in a deep V-noteh designated generally by the numeral 40, in FIG. 4, and an apron 45.
  • the notch 40 has divergent walls 42 and 44 as seen in FIG. 3, thereby to provide clearance for the divergent pattern of the spray from the depress button.
  • the button 24 has a small orifice piece 46 (also known as a mechanical brea and has a discharge channel 48 connecting the orifice piece 46 with the bore of the valve stem 16 on which the button 24 is frictionally mounted by a press-fit.
  • the button 24 may be cored to reduce the mass of the plastic of which it is constituted, in a manner indicated in FIGS. 1 and 2.
  • the depress button 24 is separated from the top wall 38 of the cap body by a plurality of arcuate grooves which are the result of the formation of the long connector strips 26, 28 and the short connector webs 30, 32, 34 and 36. While the button 24 is shown as having an oval shape, it will be understood that the button may be perfectly round, by making the connector strips 26, 28 concentric and of circular configuration rather than U-shaped, or it may be rectangular.
  • FIG. 3 it will be seen that if the outer skirt 18 and the top connector wall 38 were to be removed from the inner skirt 20, the actuator cap would still be operative and useful, such operation resulting in a small overall size of actuator cap somewhat like the embodiment of FIG. 6, as distinguished from the large or jumbo size illustrated in FIGS. 1-4, 7 and 8.
  • a non-pressurized container having a vertically movable hollow plunger or piston stem.
  • the depress button 24 will be mounted on the top of the piston stem with the actuator body secured to the non-pressurized vessel, as in FIG. 6. Due to the great extent of movement of the button 24, an effective pumping action may be produced, involving appreciable vertical reciprocation of the plunger stem of the pump.
  • FIG. 6 there is shown a non-pressurized container 50 having a hollow pump stem 52 on which there is mounted an actuator button 54 movably connected with a single depending skirt 56 of a cap body, such skirt being secured to a closure 58 of the dispenser, in which there is mounted a pump 60.
  • This figure thus shows the use of the actuator cap with a pumping-type dispenser, as distinguished from the pressurized dispenser illustrated in FIGS. 1 and 2.
  • FIG. 7 Another embodiment of the invention is illustrated in FIG. 7, wherein the main distinguishing feature over those already described resides in the depress button being substantially rectangular in shape, and in the elongate connecting strips being U-shaped with straight sides and straight bottom portions.
  • outer and inner skirts are designated respectively 18a and 20a, these being connected by a top wall or bridging portion 38a which dips downward a substantial distance at the front portion, providing an apron 62.
  • the depress button 24a is connected to the inner skirt 20a by a plurality of U-shaped outer and inner elongate connector strips 261:, 28a with the inner strip being joined to the button by short webs 34a.
  • the ends of the elongate strips 26a, 28a are joined by short webs 30a, and intermediate their ends the elongate connector strips are also joined by short webs 32a.
  • the outer elongate connector strip 26a is joined to the top wall portion 38a by short webs 36a.
  • the functioning and operation of the actuator cap illustrated in FIG. 7 is similar to that already described in connection with the preceding figures.
  • the depress button 24a has an orifice piece 46a, and when the button is depressed the material which is to be dispensed, is sprayed or discharged from the orifice piece.
  • the depress button 24a has an extended straight line vertical movement suitable for pump mechanisms of pumping type dispensers, as well as for the vertically movable valve stems of pressurized dispensers.
  • FIG. 8 Still another embodiment of the invention is illustrated in FIG. 8. This embodiment is distinguished from the preceding embodiments in that but .a single elongate connecting web is utilized, between the depress button and the cap body portion. With such arrangement, a somewhat more limited movement can be expected of the button, but by making the connecting strips quite thin and utilizing angular or curved configurations, and also by using a very flexible plastic substance the extent of movement of the button may still be considerable and of a straight line nature, even though the elongate connecting strip experiences some slight twisting or temporary deformation.
  • the outer and inner skirts are labelled 18b, 20b and the top bridging wall is indicated at 3812.
  • the top wall 38b has a front dip, providing an apron 62b below the orifice piece 461).
  • the U-shaped connectingstrip 28b is also, at the center of its yoke portion, connected to the depress button 24! by a third connecting web 34!), and the strip is connected at points intermediate its ends to the top cap wall 38b by short connecting webs 32b.
  • the depress button 24b is capable of a rocking or arcuate movement prior to the cap being assembled to the dispenser.
  • the button will be controlled as to its type of movement, by the straight line movement which characterizes the discharge stem.
  • the embodiment of FIG. 8 is best used with pressurized valve controlled dispensers and with pumping type dispensers wherein a relatively short stroke is required.
  • a one-piece plastic actuator and nozzle for small dispensers comprising in combination:
  • said button having means for mounting it on a tubular discharge stern of a dispenser with said passage and nozzle in communication therewith,
  • said cap body including integral tie webs connecting opposite forward portions of the button to forward portions of the connecting strip at spaced points and in spaced relation therewith,
  • connecting means comprising integral outer tie webs connecting the connecting strip to said other end of the cap body at a plurality of spaced points and in spaced relation therewith,
  • tie webs being disposed in staggered relation with each other to provide for maximum relative 5 movement between the button and said other end of the cap body.
  • connection means, connecting strip and tie web formations provide devious connections between the depress button and said other end of the cap body.
  • said connecting means includes a second integral, elongate connecting strip of substantially U-shape, disposed in said plane and outside of the firstmentioned U-shaped strip but in closely spaced relation thereto,
  • connection means, connecting strip and tie web formations provide devious connections between the depress button and said other end of the cap body.
  • said connecting strips comprise straight leg portions and straight yoke portions joining the straight leg portions.
  • cap body, top wall and skirt being integral and molded as a single piece.
