ACTUATQR'OVER WITH SLIDABLY RETRACTING SIDEPROJECTING ZLE F'il ed March 21, 67

l l J l u INVENTOR. PAUL M. KOTUBY BY/W United States Patent 3,386,631 ACTUATOR-OVERCAP WITH SLIDABLY RE- TRACTING SIDE-PROJECTING NOZZLE Paul M. Kotuby, Naugatuck, Conn., assignor to The Risdon Manufacturing Company, Naugatuck, Conn., a

corporation of Connecticut Filed Mar. 21, 1967, Ser. No. 624,828 7 Claims. (Cl. 222--402.11)

ABSTRACT OF THE DISCLOSURE An actuator-overcap combination for dispensing con tainers, more especially self-pressurized or aerosol type containers, incorporating means for sliding an actuating member of the combination from a centered, nondispensing position in the overcap to a position eccentric of the cap to allow the actuator to be manually operated to release product from the container.

This invention pertains to a cap for a dispensing container, and it pertains more particularly to an overcapactuator assembly especially suited for use in conjunction with a pressurized or aerosol type of dispensing container, although applicable to other type of containers as well.

It is a principal purpose of the invention to provide a closure cap for covering that end of a dispensing container incorporating a valve or other means for controlling the release of the product. The particular cap of the invention is of the type which is adapted to be more-or-less permanently secured to the valved end of the container in enclosing relation thereto and which has provision incorporated in it for permitting manual actuation of the container valve and for directionally controlling the release of product without requiring the removal of the overcap.

The invention provides an overcap-actuator assembly which is both utilitarian and aesthetically pleasing. The utilitarian aspects of assembly include that of providing a flat upper surface allowing the nesting of superimposed containers in stable, stacked formation for convenient storage and effective shelf display. The design and arrangement of components afford minimum exposed crevices, depressions and the like which commonly cause an accumulation of soot about the valve stem and mounting at the end of the container. The invention also incorporates means in the actuator-overcap assembly to prevent inadvertent dispensing of product when contact is made unintentionally with the valve stem or other valve operating member of the dispensing container.

Still further, the invention affords means for enchancing the aesthetic appearance of the container, whereby to make it more attractive to the customer and increase its sales appeal.

Finally it is an important aspect of the invention to provide an actuator-overcap assembly which, concomitantly with satisfaction of the foregoing objectives, still meets the practical commercial requirements of design simplicity, ease of manufacture and low cost.

II he invention is illustrated by the specific embodiments which are illustrated in the accompanying drawings and described in detail hereinafter of certain presently preferred forms of actuator-overcap assemblies. It is understood of course that such illustration and description are exemplary and that various changes can be made to provide similar units embodying the concept as disclosed herein and defined in the appended claims.

In the drawings,

FIG. 1 is a perspective view in side elevation of a typical cylindrical aerosol type dispensing container incorporating an actuator-overcap assembly of the invention 3,386,631 Patented June 4, 1968 ICC FIG. 2 is a fragmentary view, partly in cross section of the actuator-overcap seen in FIG. 1, but with the actuator in a different position relative to the cap;

FIG. 3 is a perspective view in side elevation, on a slightly enlarged scale, of a cap portion of the actuatorovercap seen in FIG. 1;

FIG. 4 is a perspective view from above of a portion of dispensing container from which the overcap has been removed and showing a coupling member forming a part of a valve actuator;

FIG. 5 is a perspective view of a spout portion of the actuator which complements the coupling member seen in FIG. 4; and

FIG. 6 is a fragmentary view in side elevation, certain parts being shown in cross section, of a modification of the assembly shown in FIG. 2.

Dispensing container 10 comprises the usual cylindrical metal can which closed at its bottom end and provided at its upper end with a valved outlet. As seen more particularly in FIG. 2, the valve assembly 12 comprises a conventional cupped or dished valve mounting ferrule 14 whose periphery is rolled over the lip 16 of the upper edge of container 16) to close the upper end. of the can and support the valve therein. Container 10 has a reduced neck section 18 immediately below lip 16, and hollow overcap 20 of molded plastic is seated on the top of the container, gripping the latter by forcing an internal bead 22 of the cap over lip 16 into engagement with the reduced neck section 18. Cap 20 thus encloses the valve assembly 12 and upper end of container 10 and is ordinarily not intended to be removed from the container by the user.

As best seen in FIGS. 1 and 3, cap 20 has a substantially flat transverse top wall 24 which is interrupted by a slot 26 extending diametrically across and partially down opposite the sides of the cap. The slot provides access to the interior of the cap and is normally completely occupied by a discharge spout member 30 of generally elongated rectangular shape and configuration suitable to be received in and to conform closely wtih the opposite margins 32 of slot 26.

Spout member 30 may conveniently be formed of molded plastic and is provided in its body portion with a discharge passage 34 opening at one end upon an end to 7 face 35 of the spout member, and opening at its other end on the undersurface 38 of the member.

Spout member 30 is superimposed within the overcap 20 upon a coupling member 40 contained entirely within cap 20 and having a socket 42 for the reception of the conventional tubular valve stem 44 of the valve assembly 12. Socket 42 is desirably stepped to provide a shoulder 46 which serves as an abutment for limiting insertion of the stem 44 into member 40. The reduced end of socket 42 opens unto the upper surface 48 of member 40 and, in certain positions of spout member 30 as Will be more fully described herein, registers with the inner end of passage 34 in that member.

Both the coupling member 40 and the spout member 30 are formed adjacent their abutting surfaces 48, 38, respectively, with spaced, parallel, generally diametrically extending, complementary overhanging wall portions. In member 30 these take the form specifically of the side walls 50 of a dovetail slot extending across the under surface 38 of the member. In member 40, the comple mentary overhanging walls are formed by the outwardly sloping surfaces 52 extending along opposite sides of the member adjacent its upper surface 48. Thus in the as sembled actuator the respective overhanging wall portions constitute an interfitted mortise and tenon extending diametrically of the cap. This prevents separation of the members 30, 40, axially of the cap while permitting relative sliding movement of such members diametrically thereof.

In the position of the parts illustrated in FIG. 2, wherein spout member 30 is positioned concentrically of the cap so as to completely fill slot 26 therein, the inner end of passage 34 in member 30 and the reduced outlet of socket 42 in member 40 are out of registry. In such position, the outlet from the tubular valve stem 44 is blocked so that product cannot be discharged through the stem. However, when spout member 30 is slid diametrically of the cap to the position illustrated in FIG. 1, so that it is positioned eccentrically of the cap with the spout projecting laterally therefrom, then in that position registry occurs between the inner end of passage 34 and the re duced outlet of socket 42. Product from the container may then be discharged through tubular valve stem 44 and is directed by spout member 30 to the outlet of passage 34 on end face 36 of the spout. Release of the product from the container is of course obtained by manually pressing the valve stem 44, either in an axial direction or by tilting it, both of which arrangements are conventional with aerosol valves. This manual depression of the valve stem is of course accomplished indirectly in this instance through finger pressure applied to the serrated upper surface 39 of spout member 30.

In the form of the invention illustrated here, means is incorporated for resiliently restricting sliding movement of the spout member on coupling member 40. This is obtained by providing a suitable friction bump or protuberance 35 on the undersurface of spout member 30, and a corresponding detent or depression 45 in the upper surface of member 40, whereby the detent arrangement is effective in the nondispensing position of the spout member. This tends to keep the spout member in its non-dispensing position and prevent accidental discharge of product.

A further provision is also incorporated in the device as here shown for more positively locking the valve actuator assembly 30, 40, in cap 20 so as to prevent manual depression of the valve stem 44. This is effected by a mortise and tenon coaction between spout member 39 and cap 20 when the spout member is centered in the slot 32 of the cap, but which engagement is interrupted when the spout member 30 is moved laterally of the cap, whereby to free the member for manual depression.

With reference to FIG. it will be noted that spout member 30 is expanded or outwardly flared, as at 37, adjacent its upper surface 39 and extending substantially along the length of that member. As seen best in FIG. 3, the rear margin 33 of slot 26 is sloped inwardly to provide an inward projection or overhang along a short portion of the margin of the slot. So long as spout member 30 is in its centered position in the cap, the enlarged or flared surfaces 37 of that member abut the inwardly sloping overhanging surfaces 33 in the margin of slot 26. It is not then possible to depress spout member 30 relative to cap 20. However as soon as spout member 30 is slid laterally of the cap to a point where the back edge of member 30 passes beyond the flared surfaces 33 in the margin of the slot, there is no further restriction to axial motion between the cap and spout.

In FIG. 6, an arrangement is shown which is basically the same as that already described, except that the abutting surfaces 38' of spout member 39 and 43' of coupling 40 are disposed in a plane which slopes upwardly in the direction of movement of the spout member from its concentric to its eccentric positions in the cap. Members 39, 46' are provided with interfitting mortise and tenon as before permitting the members to be moved laterally, i.e. diametrically, of the cap but preventing axial separation of them. In the centered or concentric position of spout member 30', its upper surface 39 is depressed somewhat below the upper surface 24' of cap 2%, which thus affords added protection against inadvertent or accidental actuation of the member. However, upon sliding spout member 30' to its eccentric or dispensing position, by reason of the inclined plane of abutment between that member and a coupling member 40', the spout assumes an elevated position in which its upper surface is at least substantially flush with the surface 24 of the cap so that actuation of the valve is facilitated.
