Abstract
Abstract A tamperproof securing device for spray tops of aerosol cans comprising a nozzle cover member or shield specifically configured to be mounted in or adjacent to a groove-like recess extending along the diameter of the spray cap. A spray button extends through an aperture in the cap and is at least partially surrounded or encased by the shield due to one or more depending flanges formed thereon. Shield is attached to the spray cap by means of outer peripheral portions configured to fit within depressed portions of the spray cap along the upper edges of the recess groove. Alternately the shield may be attached to the spray cap by forming its outer peripheral portion somewhat thinner than the remaining inner portion and attaching the thin peripheral portion to the area adjacent the upper edge of the recessed groove without forming a depressed area thereabout. A score line or weakened line may be formed at the approximate juncture between the upper edge of the recessed groove and the relatively thin peripheral portions of the shield.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
130 words
A tamperproof securing device used in combination with a spray cap for aerosol cans, the cap including a groove-like recess extending along a diameter thereof, an aperture formed in the cap at the approximate center of the recess, whereby a spray nozzle may extend therethrough, the recess increasing in width from the center to both sides and sloping down towards the top of the can; a cover member configured to correspond to the geometric shape of the recess and at last partially enclosing the nozzle, sais cover member comprising at least one dependent flange extending tranversely of the recess length and bent towards the base of the recess, said cover member being wider than the groove-like recess and including peripheral bearing portions bearing on and connected to the spray cap.
Claim 2
Dependent Claim
130 words
A tamperproof securing device used in combination with a spray cap for aerosol cans, the cap including a groove-like recess extending along a diameter thereof, an aperture formed in the cap at the approximate center of the recess, whereby a spray nozzle may extend therethrough, the recess increasing in width from the center to both sides and sloping down towards the top of the can; a cover member configured to correspond to the geometric shape of the recess and at last partially enclosing the nozzle, sais cover member comprising at least one dependent flange extending tranversely of the recess length and bent towards the base of the recess, said cover member being wider than the groove-like recess and including peripheral bearing portions bearing on and connected to the spray cap.
Claim 3
Dependent Claim
45 words
a securing device as in claim 1 comprising depressions on said cap correspondingly configured to said peripheral bearing portions, said peripheral bearing portions and said depression means dimensioned to allow the surface of the spray cap and the peripheral bearing portions to be substantially co-planar.
Claim 4
Dependent Claim
31 words
A securing device as in claim 1 comprising a cap having a substantially even, underpressed upper surface portion, said peripheral portions configured to extend beyond the width of the groove-like recess.
Claim 5
Dependent Claim
49 words
A securing device as in claim 1 wherein said peripheral bearing portions are dimensioned thinner than the remainder of said cover member which covers the groove-like recess, the surface of said peripheral bearing portions mounted on said cap so as to be co-planar with the surface of the cap.
Claim 6
Dependent Claim
54 words
A securing device as in claim 1 comprising a depending flange mounted on the rear of said cover means and extending transversely of the length of the groove-like recess, said rear flange extending partially into such recess and partially defining a space between the rear flange and the recess base for removing the cover.
Claim 7
Dependent Claim
18 words
A securing device as in claim 1 wherein said peripheral bearing portions are adhesively connected to said cap.
Claim 8
Dependent Claim
22 words
A securing device as in claim 1 comprising snap connector means interconnected between said peripheral bearing portion mounted on the spray cap.
Claim 9
Dependent Claim
25 words
A securing device as in claim 7 wherein said snap connector means comprises peg means interconnected between said peripheral bearing portions and said spray cap.
Claim 10
Dependent Claim
28 words
A securing device according to claim 1 wherein said cover member comprises tear line means formed thereon adjacent to the upper edge of the recess of the cap.
Claim 11
Dependent Claim
28 words
A securing device according to claim 1 wherein said cover member further comprises strengthening means including a thickened portion configured to cover the groove-like recess on the cap.
Claim 12
Dependent Claim
17 words
A securing device according to claim 1 comprising the cover member being made from a plastic material.
Claim 13
Dependent Claim
18 words
A securing device according to claim 1 further comprising the cover member being made from an aluminum material.
