Abstract

Abstract In combination, a safety container and cap assembly, the container having an elongated neck with at least two sets of threads of opposite pitch with respect to each other, one arranged proximally and one arranged distally with respect to the container, the cap having at least two sets of threads of opposite pitch with respect to each other, one arranged proximally and one arranged distally with respect to the cap complementary to and engageable with the respective sets of threads of the container, the set of threads proximal to the container having a greater diameter than that of the set of threads distal to the container, thereby permitting the distal threads of the cap to clear the distal threads of said container, the sets of threads of the container and the cap being sufficiently spaced apart so that only one set of complementary threads are engageable at one time.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 209 words
In combination, a safety container and cap assembly comprising: 1. a container having an open-ended neck, said neck having provided on the outer surface thereon: a. a proximally arranged male thread set, and b. an axially spaced distally arranged male thread set of opposite pitch and smaller diameter with respect to said proximally arranged thread set, 2. a cap having a top wall and a cylindrical side wall, said cap having provided on the inner surface of said side wall: a. a proximally arranged female thread set complementary to and adapted to engage the distally arranged thread set of said neck, and b. an axially spaced distally arranged female thread set of opposite pitch with respect to said proximally arranged thread set (2a) and complementary to and engageable with the proximally arranged thread set of said neck, the axial spacing of the respective threaDs on said cap being greater than the axial spacing of the respective threads on said neck, the thread sets of said neck and said cap being so arranged that only one complementary pair of thread sets of said neck and said cap can be engaged at any given time, whereby removal of said cap requires rotation first in one direction and then in the other.
Claim 2
Dependent Claim 209 words
In combination, a safety container and cap assembly comprising: 1. a container having an open-ended neck, said neck having provided on the outer surface thereon: a. a proximally arranged male thread set, and b. an axially spaced distally arranged male thread set of opposite pitch and smaller diameter with respect to said proximally arranged thread set, 2. a cap having a top wall and a cylindrical side wall, said cap having provided on the inner surface of said side wall: a. a proximally arranged female thread set complementary to and adapted to engage the distally arranged thread set of said neck, and b. an axially spaced distally arranged female thread set of opposite pitch with respect to said proximally arranged thread set (2a) and complementary to and engageable with the proximally arranged thread set of said neck, the axial spacing of the respective threaDs on said cap being greater than the axial spacing of the respective threads on said neck, the thread sets of said neck and said cap being so arranged that only one complementary pair of thread sets of said neck and said cap can be engaged at any given time, whereby removal of said cap requires rotation first in one direction and then in the other.
Claim 3
Dependent Claim 72 words
A safety container and cap assembly according to claim 1, wherein the distal thread set on said neck and the proximal thread set on said cap are both right-handed, and the proximal thread set of said neck and the distal thread set of said cap are both left-handed, and whereby final closure is accomplished by engagement of the distal thread set of said neck and the proximal thread set of said cap.
Claim 4
Dependent Claim 152 words
a cap having a top wall and a cylindrical side wall, said cap having provided on the inner surface of said side wall: a. a proximally arranged female thread set complementary to and adapted to engage the distally arranged thread set of said neck, and b. an axially spaced distally arranged female thread set of opposite pitch with respect to said proximally arranged thread set (2a) and complementary to and engageable with the proximally arranged thread set of said neck, the axial spacing of the respective threaDs on said cap being greater than the axial spacing of the respective threads on said neck, the thread sets of said neck and said cap being so arranged that only one complementary pair of thread sets of said neck and said cap can be engaged at any given time, whereby removal of said cap requires rotation first in one direction and then in the other.
Claim 5
Dependent Claim 152 words
a cap having a top wall and a cylindrical side wall, said cap having provided on the inner surface of said side wall: a. a proximally arranged female thread set complementary to and adapted to engage the distally arranged thread set of said neck, and b. an axially spaced distally arranged female thread set of opposite pitch with respect to said proximally arranged thread set (2a) and complementary to and engageable with the proximally arranged thread set of said neck, the axial spacing of the respective threaDs on said cap being greater than the axial spacing of the respective threads on said neck, the thread sets of said neck and said cap being so arranged that only one complementary pair of thread sets of said neck and said cap can be engaged at any given time, whereby removal of said cap requires rotation first in one direction and then in the other.
Claim 6
Dependent Claim 42 words
A safety container and cap assembly according to claim 2, wherein a recess is provided in the side wall of said cap intermediate the proximal and distal thread sets thereof to permit the proximal thread set of said neck to travel therein.
Claim 7
Dependent Claim 66 words
An assembly according to claim 1, wherein the distal thread set of said neck and the proximal thread set of said cap are left-handed and the proximal thread set of said neck and the distal thread set of said cap are right-handed, and whereby final closure is accomplished by engagement of the proximal thread set of said neck and the distal thread set of said cap.
Claim 8
Dependent Claim 13 words
An assembly according to claim 1, wherein said container is formed of glass.
Claim 9
Dependent Claim 15 words
An assembly according to claim 1, wherein said container is formed of a plastic material.
Claim 10
Dependent Claim 15 words
An assembly according to claim 1, wherein said cap is formed of a plastic material.
Claim 11
Dependent Claim 13 words
An assembly according to claim 1, wherein said container is formed of metal.
