Abstract
Abstract The specification describes a mixing container for dissolving corrosive or poisonous chemicals, supplied in a sealed package, in a solvent. The container comprises a filling neck, which can be closed by a lid, for the chemicals, more particularly for the production of a plant protective spraying liquid, characterized by the following features. The filling neck is provided with a sleeve extension, directed towards the interior of the container, for receiving an as yet unopened chemical package. The sleeve extension in the interior part has an opener for the package and this opener becomes effective on pressing the package into the sleeve extension and the opener causes the content of the package to move past it into the container.

Independent Claim
286 words
A mixing container for dispensing at least one material contained in at least one capsule into a vessel containing a second material, comprising: a vessel for containing the second material; said vessel having an open, but closable, filling neck; a sleeve shaped extension projecting into said vessel from said filling neck to an inner end; said extension having an internal cross section defined by internal walls thereof; a cutting knife near said extension inner end and located in said extension, and having a cutting edge facing toward said neck; said knife cutting edge extending completely across said extension between its said internal walls, whereby said knife cutting edge is so shaped and of such length and size as to cut completely through a capsule pressed against said knife edge; at least one capsule positionable in said extension by insertion through said neck and having a width substantially of said extension cross section; said capsule being formed of a material capable of being cut through by a knife edge and said capsule being so shaped that upon said capsule being pressed against said knife edge, said knife slices completely through said capsule in a manner that said capsule can pass said knife and move into said vessel; a capsule pressing punch insertable into said neck and adapted to pass through said extension; said capsule being located between said punch and said knife; said punch having a portion having a cross section that is substantially said cross section of said extension and that is shaped to meet with said knife cutting edge along substantially the entire length of said knife cutting edge; said punch being adapted to press against said capsule and press said capsule past said knife.
Claim 2
Dependent Claim
286 words
A mixing container for dispensing at least one material contained in at least one capsule into a vessel containing a second material, comprising: a vessel for containing the second material; said vessel having an open, but closable, filling neck; a sleeve shaped extension projecting into said vessel from said filling neck to an inner end; said extension having an internal cross section defined by internal walls thereof; a cutting knife near said extension inner end and located in said extension, and having a cutting edge facing toward said neck; said knife cutting edge extending completely across said extension between its said internal walls, whereby said knife cutting edge is so shaped and of such length and size as to cut completely through a capsule pressed against said knife edge; at least one capsule positionable in said extension by insertion through said neck and having a width substantially of said extension cross section; said capsule being formed of a material capable of being cut through by a knife edge and said capsule being so shaped that upon said capsule being pressed against said knife edge, said knife slices completely through said capsule in a manner that said capsule can pass said knife and move into said vessel; a capsule pressing punch insertable into said neck and adapted to pass through said extension; said capsule being located between said punch and said knife; said punch having a portion having a cross section that is substantially said cross section of said extension and that is shaped to meet with said knife cutting edge along substantially the entire length of said knife cutting edge; said punch being adapted to press against said capsule and press said capsule past said knife.
