TWO-COMPONENT PACKAGE Russian patent published in 2009 - IPC B65D51/28 

FIELD: containers.

SUBSTANCE: two-component package includes a container with a threaded neck filled with liquid product and a capsule with concentrated product mounted in the container cover. The container cover is made of two parts, which form the inner space of the capsule. The first part represents a multi-piece shell, bottom of which is covered with a diaphragm made of material impervious to concentrated and liquid products. The shell wall envelopes the container neck on both sides and is screwed onto the neck. The second part is made of coaxially located tubular sections integrated by a common end section and is connected to the first part so that the inner tubular section is inside the shell and the outer tubular section is outside the shell. The first and second parts are interconnected through a spline joint to allow for axial movement. The cover is fitted with two-position clamping mechanism and the inner tubular section is sharp edged to open the capsule.

EFFECT: simplified two-component package design and additional guarantee of product sterility after component mixing.
