Abstract

A spray through cap (10) for an aerosol can comprises an aperture (19) through which liquid from the can is sprayed without removing the cap (10) from the can and a hinged flap (21) formed integrally with the cap (10), the flap (21) having a depending thimble (24) for engaging a valve button (12) of the can so that, when the flap (21) is depressed, the button (12) is operated, <IMAGE>

Description

SPECIFICATION Cap This invention relates to a cap for an aerosol can.
Most aerosol cans have a simple cup-like closed cylindrical cover which has to be removed by the user to gain access to the actuating valve.
Often such caps are discarded or misplaced which makes the can less attractive. In many cases caps cannot be dispensed with because this would leave the valve open to actuation by other cans when stacked and in transit etc.
Caps have been proposed which allow spraying without removal thereof from the can (so-called "spray-through caps"), but they have been made from several parts moulded separately and then assembled, making them economically unattractive compared with plain removable caps.
An object of the present invention is to provide a "spray-through" cap which is cheap to manufacture.
Accordingly the invention provides a spraythrough cap, for an aerosol can, in the form of a single moulding defining a shell having: at an open end thereof means for attachment to an aerosol can; an aperture in side walling disposed to accommodate a jet of fluid expelled from a conventional outlet of the can; and means allowing actuation of a valve of the can without removal of the cap.
A preferred cap of the invention can have one or more of the following features:- (a) side walling of the cap is generally cylindrical; (b) top walling of the cap is generally circular; (c) an actuator portion of the cap is a part disposed below the level of the top walling and removable by finger pressure; (d) the actuator portion is connected to the side walling by being integrally moulded therewith, the junction between the two parts forming a hinge; (e) the actuator portion can carry an inverted slotted thimble for engagement over the conventional valve of an aerosol can; (f) the side walling adjacent the aperture is shaped to provide an embrasure; and (g) the thimble has tapered ribs for gripping the valve and/or internal abutments for resting on the top of the valve.
The invention will be described further, by way of example, with reference to the accompanying drawings wherein: Fig. 1 is a perspective view from the front and above a preferred cap of the invention; Fig. 2 is a similar rear view; Fig. 3 is an enlarged plan view; Fig. 4 is a cross-section on line A-A; Fig. 5 is a front elevation; Fig. 6 is a cross-section on line B--B; and Fig. 7 is a rear elevation.
A preferred "spray-through" cap 10 of the invention is suitable for attachment to an aerosol can 11 (shown in dotted lines in Figs. 4 and 6) having a valve 12. The cap 10 is a single moulding from plastics material and has generally cylindrical side walling 13 and generally flat circular top walling 14. The lower free end of walling 13 has a conventional lip 1 5 for engaging the can 11. Side walling 13, over a 90 degree sector, is omitted and an embrasure 16 is formed having planar radial side walls 1 7 and a part-conical lower wall 18. The inner end of the embrasure 16 terminates in an aperture 1 9 spaced radially outwards of the axis 20 of the cap 10 (Fig. 4).
Means for allowing depression of valve 12 without removal of cap 10 is constituted by a depressable flap 21 moulded to lie slightly below the level of the upper surface of top walling 14, concave in cross-section and separated from top walling 14 by a narrow gap 22. Flap 21 is generally frusto-triangular in plan and its base is integral with side walling 1 3 opposite the embrasure 16, its connection 23 with that walling constituting a hinge, resilient because of the nature of the plastics material.
Depending from the inner free end of flap 21 is an inverted thimble 24 of cylindrical shape having a slot 25 in its side wall in register with aperture 19 and sized to be capable of engaging a conventional valve button 1 2. Ribs 26 are provided for engaging side wall of button 1 2 and abutments 27 for engaging the top of button 12.
The cap of the invention allows the aerosol can to be used without removal of the cap and is attractive in appearance and, being a single moulding, is cheap. Capped cans can be stacked without danger of accidental discharge.
The invention is not limited to the precise details of the foregoing and variations can be made thereto.
1. A cap for an aerosol can comprising an upper surface, a circumferential wall depending from the upper surface and having an aperture therein and means for actuating a valve mechanism of the can wherein the said means is operable to actuate the valve mechanism without removing the cap from the can.
2. A cap as claimed in Claim 1 wherein the said means is movably connected to the wall.
3. A cap as claimed in Claim 1 or Claim 2 wherein the said means comprises a member hinged to the wall and having a member depending from the hinged member for engaging the valve mechanism.
4. A cap as claimed in Claim 3 wherein the depending member is generally cylindrical having an aperture through which liquid from the can is expelled.
5. A cap as claimed in Claim 3 wherein the cylindrical depending member includes an elongate abutment member extending longitudinally of the cylindrical member.
6. A cap as claimed in any one of the preceding claims wherein the upper surface is substantially planar and the said means is provided with an upper surface which, in longitudinal cross sectioti of the cap, is substantially concave.
