Definitions

  • the invention relates to tamperproof receptacles provided with a rotatable cap, the latter having an annular 5 Claims 3 Drawing Figs recess for rece tion of a flexible band that includes a latch and P U.S. Cl 215/9 a manual control therefor, said latch cooperating with dimples Int.
  • one of the objects of the invention is to create a simple constructed screw cap with a lock means therefor which is easy for all adults to handle, but which cannot be opened by small children.
  • the invention accomplishes this purpose by providing the screw cap with an annular recess or circular keyway.
  • a locking device manually operable through an opening provided in the sidewall of the cap, can be shifted from a locked position (in which a hook on one terminal end portion of the flexible locking device is urged inwardly against the bottle neck along the circumference of which is provided a plurality of notches or dimples to engage the hook) to a neutral position in which the hook is freed of the notches.
  • the locking device through friction with the bottle neck is automatically shifted to its locked position so that the locking hook is moved into the first notch or dimple on the bottle neck.
  • the locking device By manual operation of the locking device, by means of the outwardly extending actuator therefor, it may now be shifted to the neutral position, at which time the locking hook is freed from the particular dimple with which it is then engaged on the bottle neck.
  • the primary object of the invention is the provision of a tamperproof receptacle which is adapted to receive a rotatable cap with the latter having an annular recess for reception of a flexible band which may be constructed of any suitable plastic or thin metallic material provided with a latch and a manual control means therefor which cooperates with dimples provided on the neck of the receptacle to thereby permit either free relative movement of the cap on the receptacle for complete removal thereof, or prevent movement thereof, depending upon the position of the manual control.
  • a further object of the invention is the provision of a suitable cap which has a portion thereof threaded for attachment to a receptacle and adjacent to the threaded area is an enlarged annular recess which is adapted to receive the flexible locking band.
  • the cap further includes an opening in one sidewall portion thereof which receives a manual control lever that is made integral with the flexible band. Substantially diametrically opposite from the opening in the sidewall of the cap is a concave recess into which the hook provided at the terminal free end portion of the flexible band may extend when the actuator is in the proper position so that the cap may be removed by an authorized person.
  • FIG. 1 shows a medicine bottle with a screw cap with lock according to the invention, viewed from the side;
  • FIG. 2 is a section on line 2-2 of FIG. I;
  • FIG. 3 is a section on line 3-3 of FIG. 2.
  • the receptacle 10 which will be referred to hereinafter as a medicine bottle,has a reduced, cylindrical neck portion provided with circumferentially spaced notches 11. Thread means 12 for reception of a screw cap 13 are provided thereabove.
  • the screw cap I3 is provided at the lower inner portion thereof with an annular groove 14 which is arranged to receive a relatively thin band of flexible material 15, one terminal end portion of which is provided with a right angularly disposed lock means 16 for a purpose that will become apparent as the description progresses.
  • this flexible band 15 is provided with an outwardly extending enlarged portion or actuator 17, which is arranged to project through the opening 18 provided in the sidewall of the cap 13.
  • a tamperproof locking means for receptacles having an annular neck portion, a threaded area, and a rotatable internally threaded cap for cooperation therewith
  • the combination comprising, circumferentially spaced locking means on the neck portion of said receptacle, a flexible locking means for cooperation therewith, said internally threaded cap being provided with a recess for reception of said flexible locking means, manually operable actuating means for the flexible locking means, and means defining an opening in said rotatable cap to provide access to said actuating means to thereby cause the flexible locking means to be engaged with and disengaged from the circumferential locking means.
