LOCKABLE CAP FOR A BOTTLE

摘要

A lockable cap, is a security feature for a medical prescription bottle. There is a dial locking mechanism that is attached to the cap. The dial locking mechanism and the cap can be attached or removed from the bottle only when the user has the correct combination on the dial lock. When the combination is incorrect a mechanism, including a dog plate within a housing, is disengaged and the inner cap cannot be removed from the bottle. The housing has pieces that snap together for a tamper proof connection between the inner components and the housing. The dog plate has a flat circular set of gear teeth, each of which allows for a single point of contact to exert enough tension to apply and remove the cap. These teeth are set away from a side wall with a gap that allows the dog plate to spin freely within the housing. Above the dog plate is the dial lock including a set of dial lock wheels containing both numeric cogs and standard cams each having one flat secant section. The cams are spring held into the numeric cogs. The flat sections on the cams work in unison with each other. Only when all the flat sections of the cams line up will the unit become unlocked.

1. A cap lock attachable to a bottle, comprising:
a single piece housing having a cap portion that has an upper surface with a plurality of first gaps therein; a rotatable dial lock mounted in the housing, said rotatable dial lock having at least four numeric cogs and cams in mechanical relationship with each other to allow the numeric cogs to spin and wherein the numeric cogs are settable to a plurality of numeric combinations; a dog plate, mounted to the housing that freely rotates within the housing, the dog plate having one or more teeth that allow sufficient torque to be exerted to rotate the cap when the lock is open; a locking plate, above the rotatable dial lock, having a plurality of second gaps and pivotally mounted to the housing, the locking plate being movable between a locked position and an unlocked position and wherein the plurality of second gaps are in alignment with said plurality of first gaps whereby said numeric cogs are held in place by said plurality of first gaps and said plurality of second gaps; the locking plate being placed in said unlocked position when said cogs are set to a predetermined one of said plurality of settings, and said locking plate being placed in said locked position when said cogs are set to one of said plurality of settings other than said predetermined setting; and the locking plate having a reset access by which the identity of said predetermined unlock setting can be reset when the locking plate is in the unlocked position and an arm of the locking plate, when the locking plate is in the locked position, blocking the reset access.
