Abstract

Abstract A safety dispenser for pharmaceutical products, or the like includes a container having an opening normally closed by two gates, one at each end of said opening, said gates being independently slidable longitudinally to bring their free ends into and out of overlapping closing position across the opening. Said gates are individually biased toward closing position by spring means formed integrally therewith. Both gates must be held open at the same time to permit passage of articles through the opening.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 163 words
Safety drug dispenser assembly including a container one all of which has an opening and a slot spaced from each end thereof, two gates each movable independently of the other toward and from closed position in overlapping relation across said opening and each being manually operable through one of said slots to move the gate toward and to hold the same in open position, each of said gates being biased in a direction to extend across and thus to automatically close said opening and normally retain the same in closed condition, and gate guiding means in the container, said assembly being characterized in that a unitary closure element mounted in the container includes a relatively rigid base portion and two arms extending from the base in opposite directions towards said opening, each arm including one of said gates and having a resilient portion integral therewith and with said base whereby the gate is normally biased toward closing position in relation to said opening.
Claim 2
Dependent Claim 163 words
Safety drug dispenser assembly including a container one all of which has an opening and a slot spaced from each end thereof, two gates each movable independently of the other toward and from closed position in overlapping relation across said opening and each being manually operable through one of said slots to move the gate toward and to hold the same in open position, each of said gates being biased in a direction to extend across and thus to automatically close said opening and normally retain the same in closed condition, and gate guiding means in the container, said assembly being characterized in that a unitary closure element mounted in the container includes a relatively rigid base portion and two arms extending from the base in opposite directions towards said opening, each arm including one of said gates and having a resilient portion integral therewith and with said base whereby the gate is normally biased toward closing position in relation to said opening.
Claim 3
Dependent Claim 40 words
Drug dispenser assembly according to claim 1 and wherein each of said gates is the free end portion of one of said arms and the gate-biasing portion thereof is integral with and operatively arranged between the gate and the base.
Claim 4
Dependent Claim 31 words
Drug dispenser assembly according to claim 2 and wherein each gate is flexible and mounted to move endwise toward and from said opening in a path determined by said guiding means.
Claim 5
Dependent Claim 37 words
Drug dispenser assembly according to claim 3 and wherein the rigid base is mounted in fixed position in the container whereby said gates are retained in operative endwise sliding relation to said guiding means and said opening.
Claim 6
Dependent Claim 48 words
Drug dispenser assembly according to claim 1 and 2 wherein a guard member is positioned in opposed spaced relation to and substantially coextensive in length with an intermediate portion of each of said arms whereby contents of the container are maintained out of impeding contact with said arms.
Claim 7
Dependent Claim 45 words
Drug dispenser assembly according to claim 1 and wherein the enclosing walls of the container are permanently joined whereby passage of pills, tablets or the like into and out of the container is effected through said opening while the gates are held in open position.
Claim 8
Dependent Claim 57 words
Drug dispenser assembly according to claim 1 and wherein releasable gate-locking means are operatively arranged between the container wall and portions of the gate-guiding means whereby said gate-carrying arms are normally retained against endwise displacement from gate-closing position and are releasable to permit such endwise movement toward open positioN by inwardly directed pressure applied to said arms.
Claim 9
Dependent Claim 46 words
Drug dispenser assembly according to claim 7 and wherein the gate-guiding means for each arm include a partition positioned to define a space between said container wall and the partition and a portion of said arm is displaceable into said space to release said gate-locking means.
Claim 10
Dependent Claim 97 words
Safety drug dispenser according to claim 1 and wherein said container includes a lateral enclosing wall secured between a top wall and a bottom wall spaced therefrom, said bottom wall having a set of gate-guiding grooves arranged opposite a set of similar guiding grooves in the top wall, portions of said grooves being positioned to extend across said opening, and said gates having edges of their overlapping end positions operatively engaged in said grooves to effectively guide said gates into closing position across said opening and to resist inward displacement of said gates when in closing position.
