Abstract

One-piece, pushbutton dispensing cap for pressurized containers comprises a pushbutton mounted in a recess in said cap and attached to the remainder of the cap by frangible connecting pins. The pushbutton is located between guide slides which guide it in translational movement axially of the cap after said frangible connecting pins have been broken by depressing the pushbutton relative to the remainder of the cap.

Claims14

Dependent claims

A dispensing cap attachable to a pressurized container of the aerosol bomb type equipped with at least one dispensing valve, said cap comprising

a peripheral jacket having a lateral wall which defines at least one dispensing orifice and an upper wall having an opening,
a pushbutton at least partially received in said opening, said pushbutton comprising at its upper part a raidally extending tongue and in its lower part a right-angled duct one axial arm of which fits the outlet of the dispensing valve and the other arm of which is substantially radial and opens into said dispensing orifice,
two internal guide webs acting as cooperating guide slides for the tongue of the pushbutton, said webs being symmetrically positioned with respect to the axis of the cap, convergent in the direction of the dispensing orifice, and each comprising a guide shoulder dividing it into two zones,
the tongue of the pushbutton comprising on its lateral walls and between its ends, a shoulder corresponding to the guide shoulders of the guide webs, the improvement according to which:
the zone of each guide web which is closest to the dispensing orifice is set back with respect to the other zone, and edges of the lateral walls of the tongue are provided with members projecting into each space between one of the lateral walls of the tongue and the corresponding guide webs, said members being adapted to slidingly cooperate with the guide slides during depression of the pushbutton,
said pushbutton having an exposed end portion extending to a location closely adjacent to a side of the peripheral jacket opposite the said at least one dispensing opening, and said axial arm of the duct being offset with respect to said end portion;
said shoulders on the lateral wall of the tongue and said guide shoulders on said jacket cooperating with each other to guide the pushbutton axially of the valve and to prevent tilting of the pushbutton toward its exposed end upon application of a force near the exposed end which tends to tilt the pushbutton with respect to the valve.
