Additive transfer device
First Claim
1. An improved additive transfer device for storing and transferring a fluid material to a solution container having an exposed stooper, comprising:
- an additive container for storing the fluid material, said additive container having a substantially rigid neck portion defining a finsh and an opening therethrough;
a pierceable stopper having a shoulder for resting against said finish of said container neck and positioned to close said opening in the additive container, said pierceable stopper including a guide channel;
a piercing pin having a point on each end, and a passageway therethrough for the flow of the fluid material said piercing pin being slidably positioned within said guide channel;
first and second resistance means comprising spaced-apart projections extending from said piercing pin and at least one annulus extending into said guide channel to position one of said piercing pin points away from said pierceable stopper in one position and to permit passage of said piercing pin point through said pierceable stopper in another position;
a hood member having a flange portion to sealably contact said shoulder of said pierceable stopper; and
sealing means positioned between said pierceable stopper and said container finish;
whereby a fluid pathway is provided between the containers to permit the fluid material within said additive container to be transferred onto the solution container when said piercing pin pierces said pierceable stopper.

Abstract
An improved additive transfer device for storing and subsequently transferring a fluid material from an additive container to a rigid or semirigid solution container having an exposed closure. The improved additive transfer device is mounted on the additive container and includes a closure assembly fabricated from three components; a pierceable stopper, a slidable piercing pin and a hood member. The closure assembly is adapted to be positioned on the solution container. The two ended slidable piercing pin is disposed in a central opening in the pierceable stopper so that one end will pierce a diaphragm contained in the pierceable stopper. Resistance elements are provided between the slidable piercing pin and the central opening in the pierceable stopper to hold the slidable piercing pin away from the diaphragm in the pierceable stopper in one position and allow the slidable piercing pin to pierce the diaphragm and retain it within the central opening in a second position.

10. An improved additive transfer device for storing and transferring a fluid material to a solution container having an exposed stopper, comprising:
-
an additive container for storing the fluid material, said additive container having a substantially rigid neck portion defining a first and second finish and an opening therethrough; a pierceable stopper having a shoulder for resting against said second finish of said neck and positioned to close said opening in said additive container neck portion, said pierceable stopper including a guide channel; a piercing pin having a point on each end, and a passageway therethrough for the flow of the fluid material said piercing pin being slidably positioned within said guide channel; first and second resistance means comprising spaced-apart projections extending from said piercing pin and at least one annulus extending into said guide channel to position one of said piercing pin points away from said pierceable stopper in one position and to permit passage of said piercing pin point through said pierceable stopper in another position; and a hood member having a flange portion to sealably contact both said container first finish and said shoulder of said pierceable stopper; whereby a fluid pathway is provided between the containers to permit the fluid material within said additive container to be transferred into the solution container when said piercing pin pierces said pierceable stopper. - View Dependent Claims (11, 12, 13, 14, 15)

16. A three piece stopper system for an additive container having a substantially rigid neck portion defining a finish and an opening therethrough and used for storing and transferring a fluid material comprising:
-
a pierceable stopper having a shoulder for resting against the finish of the additive container neck and positioned to close said opening therein, said pierceable stopper including a guide channel; a piercing pin having a point on each end, and a passageway therethrough for the flow of said fluid material said piercing pin being slidably positioned within said guide channel; first and second resistance means comprising spaced-apart projections extending from said piercing pin and at least one annulus extending into said guide channel to position one of said piercing pin points away from said pierceable stopper in one position and to permit passage of said point through said pierceable stopper in another position; and a hood member having a flange portion to sealably contact said shoulder of said pierceable stopper; whereby a fluid pathway is provided into the additive container to permit the fluid material within the additive container to transfer therefrom when said piercing pin pierces said pierceable stopper. - View Dependent Claims (17, 18, 19, 20)
