Abstract
Abstract An aerosol having a captive safety overcap which must be rotated, axially depressed, and once again rotated, with respect to the aerosol, to allow operation of the conventional button for actuating the aerosol valve. The overcap is provided with an opening which in the safety position is misaligned with respect to a button access opening in an inner cap, but when turned, depressed, and turned again, the openings are aligned so that a finger may be inserted and the valve button depressed for operating the aerosol.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
195 words
The combination with an aerosol having a movable button for operating the valve thereof and means restricting the direction of the spray, an inner cap fixed with respect to the aerosol and including a pair of spaced abutments located laterally of and rising outwardly beyond the button in an axial direction, said cap having a limited finger access opening to said button between the abutments, in combination with a captive safety overcap, spring means exerting a resilient pressure on the overcap in an axial direction, means providing for a partial rotational and axial motion of said overcap relative to said inner cap and the button, said overcap having a finger access opening in a wall thereof and a safety position wherein the overcap covers and protects the finger access opening in the inner cap so that manual access to said button for operating the same is blocked, said overcap having another rotative position wherein said opening aligns with the finger access opening in the inner cap for access to said button for operation thereof, and means restricting the overcap to the partial rotative and axial path only between said safety position and the operative position.
Claim 2
Dependent Claim
195 words
The combination with an aerosol having a movable button for operating the valve thereof and means restricting the direction of the spray, an inner cap fixed with respect to the aerosol and including a pair of spaced abutments located laterally of and rising outwardly beyond the button in an axial direction, said cap having a limited finger access opening to said button between the abutments, in combination with a captive safety overcap, spring means exerting a resilient pressure on the overcap in an axial direction, means providing for a partial rotational and axial motion of said overcap relative to said inner cap and the button, said overcap having a finger access opening in a wall thereof and a safety position wherein the overcap covers and protects the finger access opening in the inner cap so that manual access to said button for operating the same is blocked, said overcap having another rotative position wherein said opening aligns with the finger access opening in the inner cap for access to said button for operation thereof, and means restricting the overcap to the partial rotative and axial path only between said safety position and the operative position.
Claim 3
Dependent Claim
40 words
The combination of claim 1 wherein said means providing for a partial rotational and axial motion of the overcap comprises a control groove on one cap and a cooperating projection on the other cap, the projection being in the groove.
Claim 4
Dependent Claim
56 words
The combination of claim 1 wherein the means providing rotational and axial motion of the overcap comprises a control groove in one cap including a pair of circumferential groove portions offset from each other axially with respect to the aerosol, and a passage connecting said grooves, and a projection on the other cap in the groove.
Claim 5
Dependent Claim
61 words
The combination of claim 1 wherein the means providing rotational and axial motion of the overcap comprises a control groove on the exterior wall of the inner cap including a pair of circumferential groove portions offset from each other axially with respect to the aerosol, and a passage connecting said grooves, and an interior projection on the overcap in the groove.
Claim 6
Dependent Claim
66 words
The combination recited in claim 1 wherein the safety overcap is provided with a spray opening in a wall thereof diametrically opposite the finger access opening, the overcap normally blocking the spray opening when the safety cap is in safety position, the spraY opening in the safety overcap being aligned with respect to the space between the abutments when the overcap is turned to operative position.
Claim 7
Dependent Claim
66 words
The combination of claim 1 wherein the means providing for partial rotational and axial motion of the overcap relative to the inner cap comprises a control groove on one cap and means on the other cap in the groove, said groove comprising: a. an initial circumferential portion connected to, b. an axial portion connected to, c. a final circumferential portion axially spaced from the initial portion.
Claim 8
Dependent Claim
11 words
The combination of claim 6 wherein the circumferential portions are parallel.
Claim 9
Dependent Claim
15 words
The combination of claim 6 wherein the circumferential portions are in prolongation of each other.
Claim 10
Dependent Claim
178 words
In combination with an aerosol having a button actuated valve to release the aerosol contents in spray form in a predetermined direction, of an inner cap including an abutment at each side of the button, said abutments defining a diametrical opening through which the spray emerges at one end, the finger of the operator being receivable at the other end, a spring on each abutment, each of said abutments being provided externally with a partial circumferential groove, each groove including portions axially spaced with respect to the overcap and a generally axial passage from one groove portion to the other, of a safety captive overcap, said overcap having a projection in said groove for guidance and holding of the overcap thereby, said overcap being partially rotatable as limited by the grove, means on the overcap preventing access to said valve operation button when the overcap is in a rotative position wherein the projection is in one groove portion, and an opening in the overcap providing for digital access to said button at another rotative position of the overcap.
Claim 11
Dependent Claim
178 words
In combination with an aerosol having a button actuated valve to release the aerosol contents in spray form in a predetermined direction, of an inner cap including an abutment at each side of the button, said abutments defining a diametrical opening through which the spray emerges at one end, the finger of the operator being receivable at the other end, a spring on each abutment, each of said abutments being provided externally with a partial circumferential groove, each groove including portions axially spaced with respect to the overcap and a generally axial passage from one groove portion to the other, of a safety captive overcap, said overcap having a projection in said groove for guidance and holding of the overcap thereby, said overcap being partially rotatable as limited by the grove, means on the overcap preventing access to said valve operation button when the overcap is in a rotative position wherein the projection is in one groove portion, and an opening in the overcap providing for digital access to said button at another rotative position of the overcap.
Claim 12
Dependent Claim
48 words
The combination recited in claim 9 wherein said safety overcap comprises a cylindrical outer shell and a connected cylindrical inner shell, the projection being on the inner shell, there being means for passage of the spray in both shells and the digital access opening extending through both walls.
