Abstract
Abstract A child-proof closure for a medicine bottle or the like. The closure consists of a threaded cap and relatively flexible overcap or driver. The cap and driver have cooperating ratchet drive means for screwing the cap onto the bottle by rotating the driver. The driver normally is rotatable in the opposite direction relative to the cap. The cap has a recess in its outer wall and a portion of the wall of the driver is radially inwardly displaceable for engagement in the recess for delivering unscrewing torque from the driver to the cap.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
212 words
A substantially child-proof closure for a medicine bottle or the like having a threaded neck, said closure consisting of: 1. an inner cup-shaped cap having a. an annular skirt and b. a closed top, c. the inner surface of said skirt being threaded to mate with the threaded neck of the bottle, and 2. an outer cup-shaped driver having a. an annular skirt and b. a closed top at least generally complementary to the closed top of said cap, c. the length and interior diameter of the skirt of said driver being greater than the length and exterior diameter of the skirt of said cap, 3. co-operating one-way drive means on adjacent parts of said cap and said driver, said drive means being operable for screwing said cap onto said bottle neck by rotating said driver 4. and co-operating engageable drive means for unscrewing said cap by rotating said driver, said engageable drive means comprising a. at least one axially extending abutment on the outer surface of the skirt of said cap and b. at least one radially inwardly displaceable portion in the skirt of said driver which is adapted to engage said abutment when squeezed radially inwardly for transferring unscrewing torque from said driver to said cap for removing the same.
Claim 2
Dependent Claim
212 words
A substantially child-proof closure for a medicine bottle or the like having a threaded neck, said closure consisting of: 1. an inner cup-shaped cap having a. an annular skirt and b. a closed top, c. the inner surface of said skirt being threaded to mate with the threaded neck of the bottle, and 2. an outer cup-shaped driver having a. an annular skirt and b. a closed top at least generally complementary to the closed top of said cap, c. the length and interior diameter of the skirt of said driver being greater than the length and exterior diameter of the skirt of said cap, 3. co-operating one-way drive means on adjacent parts of said cap and said driver, said drive means being operable for screwing said cap onto said bottle neck by rotating said driver 4. and co-operating engageable drive means for unscrewing said cap by rotating said driver, said engageable drive means comprising a. at least one axially extending abutment on the outer surface of the skirt of said cap and b. at least one radially inwardly displaceable portion in the skirt of said driver which is adapted to engage said abutment when squeezed radially inwardly for transferring unscrewing torque from said driver to said cap for removing the same.
Claim 3
Dependent Claim
51 words
an outer cup-shaped driver having a. an annular skirt and b. a closed top at least generally complementary to the closed top of said cap, c. the length and interior diameter of the skirt of said driver being greater than the length and exterior diameter of the skirt of said cap,
Claim 4
Dependent Claim
51 words
an outer cup-shaped driver having a. an annular skirt and b. a closed top at least generally complementary to the closed top of said cap, c. the length and interior diameter of the skirt of said driver being greater than the length and exterior diameter of the skirt of said cap,
Claim 5
Dependent Claim
20 words
a second element thereof being a radially inwardly displaceable segment at the top of the side wall of said driver.
Claim 6
Dependent Claim
20 words
a second element thereof being a radially inwardly displaceable segment at the top of the side wall of said driver.
Claim 7
Dependent Claim
45 words
an inwardly directed lip at the lower end of said side wall adapted to snap beneath the lower edge of the side wall of said closure for retaining said driver on said closure, c. first co-operating one-way driving means on said closure and said driver,
Claim 8
Dependent Claim
45 words
an inwardly directed lip at the lower end of said side wall adapted to snap beneath the lower edge of the side wall of said closure for retaining said driver on said closure, c. first co-operating one-way driving means on said closure and said driver,
Claim 9
Dependent Claim
29 words
a disc-shaped top, the interior of said side wall having threads adapted to be screwed on to and off of such bottle neck, b. an outer, inverted driver having,
Claim 10
Dependent Claim

a disc-shaped top, the interior of said side wall having threads adapted to be screwed on to and off of such bottle neck, b. an outer, inverted driver having,
Claim 11
Dependent Claim
23 words
A child-proof cap for medicine bottles and the like, having threaded necks, Said cap consisting of a. an inner, inverted, cup-shaped closure having,
Claim 12
Dependent Claim
23 words
A child-proof cap for medicine bottles and the like, having threaded necks, Said cap consisting of a. an inner, inverted, cup-shaped closure having,
Claim 13
Dependent Claim
78 words
A closure according to claim 2 and an inwardly directed lip on the lower margin of the skirt of said driver for retaining said cap and said driver in telescoped relationship, said lip being axially spaced from the top of said driver a distance greater than the axial length of said cap whereby said cap and driver are movable axially relative to each other as required during reverse relative rotation of the parts of the one-way drive means.
Claim 14
Dependent Claim
30 words
co-operating one-way drive means on adjacent parts of said cap and said driver, said drive means being operable for screwing said cap onto said bottle neck by rotating said driver
Claim 15
Dependent Claim
30 words
co-operating one-way drive means on adjacent parts of said cap and said driver, said drive means being operable for screwing said cap onto said bottle neck by rotating said driver
Claim 16
Dependent Claim
49 words
A closure according to claim 2 in which the recess in the skirt of the cap extends axially thereof and is defined by substantially parallel side walls lying in radial planes and the displaceable portion in the skirt of said driver is a hingedly movable segment of said skirt.
Claim 17
Dependent Claim
75 words
and co-operating engageable drive means for unscrewing said cap by rotating said driver, said engageable drive means comprising a. at least one axially extending abutment on the outer surface of the skirt of said cap and b. at least one radially inwardly displaceable portion in the skirt of said driver which is adapted to engage said abutment when squeezed radially inwardly for transferring unscrewing torque from said driver to said cap for removing the same.
Claim 18
Dependent Claim
75 words
