Abstract

A container for diluting and dispensing materials in liquid form that consists of a primary vessel, e.g., a bottle, adapted to contain a diluent such as water and a replaceable cartridge mounted removably in the mouth of the bottle. The cartridge is provided with a laterally projecting circular flange which lies in contact with the edge of the bottle mouth. The cartridge contains a relatively small amount of a chemical concentrate that is to be diluted. A dispensing mechanism composed of a pump with a bottle cap at its lower end is used to withdraw the contents of the container. A dip tube that extends downwards from the cap is introduced into the bottle by thrusting its free end through the cartridge thereby perforating the same and in this way allowing the chemical material in the cartridge to drain into the primary container. The cap is then screwed onto the neck of the bottle. When empty, the cartridges are thrown away and replaced.

Claims

1. A dilution and dispensing container comprising a container body having a connecting means comprising an opening for receiving a concentrate cartridge, a removable and replaceable concentrate cartridge, said cartridge having a frangible top and a frangible bottom said container body having a diluent compartment, a dip tube adapted to pierce the top and bottom of the concentrate cartridge and allow the contents thereof to mix with the diluent, a cap means for closing the opening and for retaining removable cartridge in place within the connection means in the container body, the dip tube extending through the openings thus pierced in the cartridge into the diluent compartment, and a pump means communicating through the dip tube for withdrawing the diluted concentrate from the compartment.

2. The apparatus of claim 1 wherein the cartridge is provided with a laterally extending normally horizontally disposed flange having an appropriate diameter to extend over and abutt against the upper surface of the diluent compartment and the means for retaining the cartridge in place includes a flat inner surface located in abutting relationship with the upper surface of the flange for pressing the flange in sealing relationship with the upper surface of the diluent compartment to seal the same.

3. The apparatus of claim 1 wherein the cartridge comprises a pouch having a relatively brittle and frangible dome-shaped section and a piece of substantially flat sheet material sealed across the open end of the dome to provide a hermetically sealed capsule for the concentrate, said flange being defined by the sealed section between the substantially flat sheet and the dome-shaped sheet.
