Definitions

  • FIG.G is a diagrammatic representation of FIG. 1
  • the cap could be attached to the mounting cup by a small ridge or a number of small lugs extending inward from the inner rim in its lower area.
  • the cap could have a straight wall to form a friction fit on the mounting cup.
  • the fit could be a venting or ventilating design or a seal, whichever is needed.
  • the outer skirt or wall of the cap can be of sufiicient length to extend down into the groove of the container between the breast rim and seamed outer bead of the container. It can also be constructed to extend over the outer side of the rim of the container.
  • the closures outer rim and skirt may be formed in conjunction with the inner portion when the inner portion is formed in combination with an aerosol valve button to facilitate an orienting and directional system from the basic closure design.
  • One method to accomplish this would be to form the inner portion as a complete overcap to enclose the valve button and then a means to remove this overcap completely or partly for access to the valve button, then forming the outer portion in relation with the inner portion enabling the spray product to be used in a directional manner.
  • the basic shape of the cap disclosed lends itself to a nesting or stacking quality.
  • the stacking quality has an improved feature because of the rim or number of lugs or protrusions in or on any of the angled surfaces that are capable of forming a stop so as to keep the closures when stacked, one inside the other, from wedging together.
  • T AM PER-PROOFING A quality which can be incorporated into the basic design disclosed herein by forming in a manner to make it possible to apply the closure to the container in such a manner that it will be permanently attached to the container and it is necessary to destroy a portion of the closure in order to remove it from the container. This can be done by reducing the inside rim strength with an undercut or a number of holes or cuts to cause the outer portion to break off leaving the center portion intact. The center portion can then be removed more readily and can be a reuseable closure.
  • the inner closure can be formed in a shape to lift off the container and still be able to remove the contents of the container.
  • cap DIRECTIONAL-ORIENTING Another form of cap would have its outside skirt and outer rim provided with two high sides and two low sides.
  • the upper portion of the center part would be provided with a thin bead extending upwardly.
  • the center part of the cap would be undercut at its lower portion. This bead would then be removable when held between the fingers and twisted to break off the upper portion of the center part exposing the valve.
  • the outside skirt could be made lower on both sides allowing the use of the valve.
  • Another object of the invention is to provide an improved cap for a container.
  • Another object of the invention is to provide an improved cap having specific design suitable for stacking and nesting.
  • Yet another object of the invention is to provide a cap for 'aerosol containers that is simple in construction, economical to manufacture and simple and eflicient to use.
  • Another object of the invention is to provide an improved combination aerosol cap and can.
  • FIG. 1 is a partial cross sectional view of the cap and can combination according to the invention
  • FIG. 2 is a view similar to FIG, 1 of another embodiment of the invention.
