Claims
Having thus described my invention what is asserted as new is:
1. In combination:
A bottle having an open neck with an inwardly disposed lock
ledge;
A cover removably disposed on the neck;
A tumbler body disposed in the cover with tumblers normally
engaging the ledge, said tumblers having slots, all but one of the
slots having like widths, said one slot being wider than all other
slots; and
A bayonet key having blades, the number of blades being equal to
the number of slots, all but one of the blades having like widths,
said one blade being wider than all other blades, each blade being
engagable with a corresponding slot with said one blade being
engagable only with the said one slot whereby insertion of said
blades in the slots causes the tumblers to move away from the ledge
to permit removal of the cover, the cover otherwise being rotatable
but not removable.
2. The combination of claim 1 wherein pins are disposed in slots in
the bottom of the body to prevent tumblers from popping out under
certain conditions.
3. The combination of claim 2 wherein the tumblers have flippers.
Description
SUMMARY OF THE INVENTION
This invention is directed toward a bottle containing pills or the
like with a cover that can only be removed by use of a key whereby
the contents cannot be dispensed accidentally by children or
unauthorized individuals.
To this end, the bottle has an open neck with an inwardly disposed
lock ledge. A cover is removably disposed on the neck. A tumbler
body is disposed in the cover with tumblers normally engaging the
ledge. The tumblers have slots.
A bayonet key has blades engagable with the slots to move the
tumblers away from the ledge to permit removal of the otherwise
locked cover.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a side view of the invention;
FIG. 2 is a cut away top view thereof;
FIGS. 3 and 4 are different views of a bayonet type key used in the
invention;
FIG. 5 is a bottom view of the structure of FIG. 2; and
FIG. 6 is a detail view of certain parts used in the invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Referring now to FIGS. 1-6, a bottle 10 is molded with a tumble
lock ledge 12. A cover 14 contains a tumbler body 16 with tumblers
18. Tumblers 18 contain tumbler slots 20 tapered to allow movement
away from the lock ledge. The tumblers also have flippers 22.
Vertical pins 24 are snapped into certain slots 26 after the
tumblers are placed in the body to prevent tumblers from popping
out in case the key 28 is pulled out of the body when the cover is
removed from the bottle.
The key contains three parallel vertical blades 30, 32 and 34 with
downwardly curved ends and secured to head 36. Blades 30 and 32 are
identical. Blade 34 is thicker than the other two.
The cover can turn on the bottle but cannot be removed until the
key is forced into the tumbler slots in correct manner and deeply
enough so that the tumblers can be moved away from the lock ledge.
To this end, one of slots 20 shown at 20A is larger than the other
two to accommodate the broader key.
If desired, the cover and key can be color coded to match whereby
only the correct key will fit in the correct manner.
While I have described my invention with particular reference to
the drawings, such is not to be considered as limiting its actual
scope.
