Definitions

  • the cap disclosed provides a total tamper-proof design and a convenient means of holding it permanently on a container until some portion is broken or destroyed to remove the cap from the container.
  • the cap is therefore tamper-proof.
  • the cap has a shoulder that overlies the rim of the container and a second portion of the cap is crimped or seamed under an outwardly extending downwardly facing shoulder on the rim of the container.
  • a hooked rim may be formed to engage the shoulder. Where no downwardly facing shoulder is formed on the container, the rim can be heat shrunk onto the container or it can be attached by means of an adhesive.
  • a scored tab is provided in the rim to permit removal of the cap which is secured to the container and prevent removal of the cap which is otherwise fixed to the container.
  • This invention relates to caps and, more particularly, to caps suitable to be used on aerosol cans and the like.
  • Another object of the invention is to provide a cap for an aerosol can or the like, which is simple in construction, economical to manufacture and simple and eflicient to use.
  • Another object of the invention is to provide a cap for an aerosol can or the like which is tamper-proof.
  • FIG. 1 is a longitudinal cross sectional View of a cap for an aerosol can according to the invention.
  • FIG. 2 is a view similar to FIG. 1 showing another embodiment of the cap.
  • FIGS. 3, 4, 5 and 6' show other embodiments of the cap.
  • the cap shown in FIG. 1 is indicated generally at 10 and has a first cylindrical wall portion 11 having a first end 12 and a second end 13.
  • the first end 12 is closed by a disk-like closure member 14.
  • An annular portion 15 is fixed to the second end of the cylindrical portion 11 at its inner diameter and is fixed to the second cylindrical portion 17 at 16.
  • the second cylindrical portion 17 may be spun inward to form curled portion 18 which may be resiliently distorted and underlie the downwardly facing shoulder of the cylindrical portion 19 of the can 20.
  • the can 20 is of the type generally known as an aerosol can and has a breast that extends up into first cylindrical portion 11.
  • the second cylindrical portion 17 of the can 20 may be formed by rolling, spinning or other suitable process. All of the embodiments will be provided with a scored tab to permit removal as in FIG. 6 at 535.
  • the cap shown has the first cylindrical portion 111 having an upper first end 112 and a lower second end 113.
  • the first end 112 is fixed to the closed end 114- and the lower end 113 is fixed to the annular portion 15.
  • the second cylindrical portion 117 is fixed to the annular portion 115.
  • the spaced hooks 118 are formed by bending the lower end of the second cylindrical portion 117 inwardly. These hooks 118 are resiliently distorted by the shoulder 19 of the can and force it downward.
  • the cap indicated generally at 210 has a first cylindrical side wall 211 having the upper first end 212 and the lower second end 213 fixed to the closed end 214 and to the annular portion 215 respectively.
  • the annular portion 215 is fixed to the second cylindrical portion 217 and the lower end of the cylindrical portion 217 may be bent inwardly to form the hook 218 which underlies the cylinrical portion 219 on the can 220.
  • Hook 218 is resiliently distorted and it engages the downwardly dosposed shoulder of cylindrical portion 119.
  • the cap 310 has the first cylindrical side wall 311, which is fixed to the closed end 314 and to the annular portion 315, which in turn has its outer periphery fixed to the second cylindrical portion 317.
  • the second cylindrical portion 317 is bent downwardly and inwardly at 318 to underlie the downwardly facing shoulder on the cylindrical portion 319 of the can 320.
  • the cap 410 has a generally cylindrical side wall 411 which is fixed at its upper end to the closed end 414 and at its lower end to the annular portion 415.
  • the annular portion 415 is fixed at its outer periphery to the second cylindrical portion 417 of the cap.
  • the second cylindrical portion 417 fits snugly around a large diameter portion 419 of the can 420.
  • the second cylindrical portion 417 may be fixed to the cylindrical portion 419 of the can by means of an adhesive indicated at 427 and the upper upwardly facing shoulder may be fixed to the annular portion 415 by adhesive 431.
  • FIG. 6 shows a cap 510 having a first cylindrical portion 511 and a closed end 514.
  • the first cylindrical portion 511 is fixed to an annular portion corresponding to the annular portion 415 in FIG. 5 and the second cylindrical portion 517 fits over the outside of the rim of the can 520.
  • a scored tab 535 is formed by score lines 536 and 537 which are formed in the second cylindrical portion 517 and the first cylindrical portion 511 and the annular portion corresponding to annular portion 415.
  • the operator may grasp the upper end at 538 of the scored tab and pull it down so it breaks the second cylindrical portion 517 as well as a part of the first cylindrical portion thereby preventing the cap from being tampered with.
  • a cap for an aerosol can or the like comprising:
  • a relatively deep generally cylindrical cup-like portion made up of a generally cylindrical side wall having a first and a second end
  • said second cylindrical portion being adapted to be disposed concentric to the side Wall of a can
  • said can having an outwardly extending cylindrical portion of larger diameter than said side wall
  • said cylindrical portion of said can being fixed to said side wall at the upper end thereof
  • said means fixing said second cylindrical portion of .4 said cap to said can comprising an adhesive disposed between said cap and said rim
  • said scored tab being removable whereby said cap is rendered tamper-proof.
