Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
91 words
A slidable closure device adapted to be positioned on a top ridge of a milk-type carton container permitting the carton to be opened and resealed, comprising an elongated concave member having a channel therethrough and being adapted to fit snugly on the top ridge of said container to permit movement in a direction parallel to said channel; and a removable breakaway tab portion blocking at least a portion of one end of said channel with the intact and positioned tab portion functioning to ensure that said container has not been opened.
Claim 2
Dependent Claim
91 words
A slidable closure device adapted to be positioned on a top ridge of a milk-type carton container permitting the carton to be opened and resealed, comprising an elongated concave member having a channel therethrough and being adapted to fit snugly on the top ridge of said container to permit movement in a direction parallel to said channel; and a removable breakaway tab portion blocking at least a portion of one end of said channel with the intact and positioned tab portion functioning to ensure that said container has not been opened.
Claim 3
Dependent Claim
61 words
The slidable closure device of claim 1 wherein said elongated concave member possesses a lock protrusion projecting from an inner wall of said concave elongated member which acts with the container to limit movement in a horizontal direction and an obstruction portion at least partially closing said channel and acting with the container to limit movement in a second horizontal direction.
Claim 4
Dependent Claim
23 words
The slidable closure device of claim 2 wherein said lock protrusion is essentially perpendicular to said inner wall at a point of contact.
Claim 5
Dependent Claim
32 words
The slidable closure device of claim 1 wherein said elongated concave member possesses an elongated opening parallel to the direction of said channel and a pin element insertable in said elongated opening.
Claim 6
Dependent Claim
116 words
A slidable closure device on a top ridge of a milk-type carton container permitting the carton to be opened and resealed, comprising an elongated concave member having a channel therethrough and being adapted to fit snugly on the top ridge of said container to permit movement in a direction parallel to said channel, an obstruction portion at least partially blocking said channel and acting with the container to limit movement in a horizontal direction and a lock protrusion member integral with and at an opposite end of said elongated concave member and projecting from an inner wall of said concave member, said protrusion member acting with the container to limit moVement in a second horizontal direction.
Claim 7
Dependent Claim
116 words
A slidable closure device on a top ridge of a milk-type carton container permitting the carton to be opened and resealed, comprising an elongated concave member having a channel therethrough and being adapted to fit snugly on the top ridge of said container to permit movement in a direction parallel to said channel, an obstruction portion at least partially blocking said channel and acting with the container to limit movement in a horizontal direction and a lock protrusion member integral with and at an opposite end of said elongated concave member and projecting from an inner wall of said concave member, said protrusion member acting with the container to limit moVement in a second horizontal direction.
Claim 8
Dependent Claim
22 words
The slidable closure device of claim 5 wherein said protrusion is essentially perpendicular to said inner wall at the point of contact.
Claim 9
Dependent Claim
82 words
A slidable closure device, adapted to be positioned on a top ridge of a milk-type carton container permitting the carton to be opened and resealed, comprising an elongated concave member having a channel therethrough and being adapted to fit snugly on the top ridge of said container to permit movement in a direction parallel to said channel, said elongated concave member having an elongated opening parallel to said channel and a pin mounted on said container and insertable in said elongated opening.
Claim 10
Dependent Claim
82 words
A slidable closure device, adapted to be positioned on a top ridge of a milk-type carton container permitting the carton to be opened and resealed, comprising an elongated concave member having a channel therethrough and being adapted to fit snugly on the top ridge of said container to permit movement in a direction parallel to said channel, said elongated concave member having an elongated opening parallel to said channel and a pin mounted on said container and insertable in said elongated opening.
