Bottle closure having means for mixing a predetermined dose of an additive into a liquid
First Claim
1. An apparatus for introducing a component into a first liquid, the apparatus comprising:
- a first container for holding the first liquid having an opening closeable by a releasable closure, a second container containing pressurized propellant fluid located in the first container, and a conduit having a first end communicating with the second container and a second end communicating with the first container;
wherein the conduit contains an additive which is expelled from the conduit into the first liquid by the entry of the propellant fluid into the conduit on release of the releasable closure.

Abstract
The invention relates to an apparatus for introducing an additive component (131) in the form of a liquid or granulated solid into a liquid (40) stored in a first container (150). The additive component (131) is stored separately from the liquid (40) in a dip tube or conduit (132). The container (150) has an opening closed by a releasable closure (152). A second container or tank (111) containing pressurized propellant fluid (116) is positioned in the neck or closure of the first container, adjacent to the opening. The dip tube or conduit (132) has a first end communicating with the tank and a second end extending down into the first liquid in the first container. The dip tube (132) contains an additive (131) which is expelled from the dip tube into the first liquid by the entry of the propellant fluid from the tank into the dip tube on release of the releasable closure. A valve (300) may be provided at the free end of the dip tube (132) to prevent mixing of the liquid and additive during transport and/or storage. The dose of additive may be accurately measured, and the action of the propellant ensures that all the additive is expelled into the liquid. The additive may be provided in liquid or pourable solid form.

4. An apparatus for introducing a component into a first liquid, the apparatus comprising:
-
a first container for holding the first liquid having an opening;
a releasable closure adapted to close said opening; and
an insert located adjacent to said opening;
wherein the releasable closure comprises an integral closure container containing a propellant fluid;
wherein said insert comprises a first chamber for receiving said integral closure container and a hollow rupturing member extending into said first chamber and defining a second chamber inside said rupturing member;
wherein said first chamber is provided with openings to allow the passage of said first liquid through said insert;
wherein said closure container includes a rupturable member adapted to be ruptured by said rupturing member; and
whereinthe apparatus further comprises a conduit having a first end communicating with the second chamber and a second end communicating with the first container, the conduit containing an additive which is expelled from the conduit into the first liquid by the entry of the propellant fluid into the conduit on release of the releasable closure. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of introducing an additive in the form of a liquid or granulated solid into a liquid, comprising:
-
introducing a predetermined quantity of the additive into a conduit at least partially closed at one end and communicating with a container containing pressurized propellant fluid at the other end, installing the conduit and container in a vessel containing the liquid, closing the vessel with a releasable closure, and removing the releasable closure so that the liquid in the vessel is at atmospheric pressure, thereby forcing the pressurized propellant fluid from the container into said conduit so as to open the at least partially closed end of the conduit and expel the additive from the at least partially closed end of the conduit into the liquid.
