Definitions

  • 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 clue to one or more depend ing 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.
  • 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.
  • This invention relates to a tamperproof securing device of the type designed to be removably secured to the spray cap of an aerosol container such that the spray button is at least partially encased in order to prevent inadvertent or unauthorized use of the container without complete removal of the device.
  • a guard comprising webs or flanges is molded on the body of the spray cap affixed to theh top of the body of the container.
  • the relative complicated and expensive tooling needed for the production of these prior art devices make their manufacture complex and of course expensive.
  • Other known devices of this type secure a guard to the cap after its formation by subsequently sticking, welding or the like.
  • This structure also requires specialized production facilities and automated techniques. Accordingly, such structures have been found to be uneconomical.
  • Other tamperproof guards presently available merely cover the spray button in an attempt to prevent its actuation. However this type design provides unsatisfactory security against unauthorized use, since a tool can be inserted below the guard.
  • a tamperproof device of the general type described which can be manufactured simply and economically and which includes a structure which renders the device versatile enough to be attached to conventional spray caps without calling for any structural change thereof.
  • Such a versatile structure has a further economical advantage in view of the fact that it can be manufactured, installed using available tools, production facilitates etc.
  • Such a structure shows definite tamperproof protection and makes removal of the guard readily obvious.
  • such a tamperproof device should be efficient while giving the spray top an attractive and striking appearance as a further stimulus to its purchase.
  • This invention relates to a tamperproof securing device for spray caps of aerosol cans comprising a nozzle shield means configured to fit over a spray cap which is formed with a groove-like recess.
  • the recess extends along a diameter of the spray cap.
  • a spray head or nozzle extends through an aperture at the center of the recess, the same increasing in width in the center to both sides and sloping down towards the top of the can.
  • the nozzle shield means covers the spray head or nozzle and has at least a first dependent flange extending transversely of the recess length and bent towards the base of the recess.
  • the cover member or nozzle shield means is configured to fit within a depressed area of the spray cap so as to be substantially coplanar with the spray cap upper surface. Consequently, standard spray cap configurations must, if they are to be used along with the present invention, be formed with corresponding indentations or a depressed area on both sides of the groove-like recess. Alternately, the depressions are not formed in the spray cap and the peripheral portions of the shield means which bears on the spray cap are much thinner than those part of the covere which cover the groove-like recess. In this embodiment the top of the peripheral bearing portions are substantially coplacess. The difference in height between the top surface of the spray cap and the top surface of the shield means is not a disadvantage and is preferably one millimeter or less.
  • the shield means is connected by the peripheral bearing surfaces to the spray cap either to be releasable by the use of force or non-releaseable wherein the peripheral bearing portions remains attached to the spray cap. If releasably mounted, it is apparent that the correspoding places on the spray top were mounted, that the shield has been removed. If non-releaseably connected to the srpay cap the shield is formed with perforations or tear-off lines, preferably along the inside or upper edges of the recess of the cap, enabling the shield means to be separated from the peripheral bearing portions by the use of force. Such removal is made apparent from those bearing portions which remain on the spray top.
  • peripheral bearing portions may be secured to the spray cap by adhesive application or welding.
  • additional securing means may be provided between the cover and the spray cap in the form of a peg or pin or similar connector or by a catch-like connection.
  • Additional structural features of the present invention include the shield having, rearwarly of the spray head or nozzle, a second depending flange which extends substantially tranversely to the length of the groove-like recess. This flange extends only partially into the recess and provides space for a finger hole for removing the cover.
  • the invention accordingly comprises an article of manufacture possessing the features, properties and relation of elements which will be exemplified in the article hereinafter described, and the scope of the invention will be indicated in the claims.
