A method for filling a cavity with a quantity of particulate material

Abstract

A method for filling a cavity (2, 15.1, 15.2) with a quantity (12.1, 12.2) of particulate material, comprising the steps of filling a chamber (4, 10.1, 10.2) with its open side facing upwards with the quantity (12.1, 12.2) of particulate material, positioning the opening of the cavity (2, 15.1, 15.2) opposite the opening of the filled chamber (4, 10.1, 10.2), and thereafter rotating the chamber (4, 10.1, 10.2) and the cavity (2, 15.1, 15.2) so that the cavity (2, 15.1, 15.2) is positioned with its open side facing upwards and the chamber (4, 10.1, 10.2) with its open side facing downwards, whereby the quantity (12.1, 12.2) of particulate material is emptied into the cavity (2, 15.1, 15.2). A corresponding device comprising a chamber (4, 10.1, 10.2), filling means (22, 23, 24) for filling the chamber (4, 10.1, 10.2) with the quantity (12.1, 12.2) of particulate material, operating means (29) for positioning the opening of the cavity (2, 15.1, 15.2) opposite the opening of the chamber (4, 10.1, 10.2), and conveyor belt (20) for rotating the chamber (4, 10.1, 10.2) and the cavity (2, 15.1, 15.2) so that the cavity (2, 15.1, 15.2) is positioned with its open side facing upwards and the chamber (4, 10.1, 10.2) is positioned with its open side facing downwards.

Description

technical field [0001] The invention relates to a method and a device for filling a recess with a quantity of particulate material, said method comprising the step of filling a chamber with an open side at least partially facing upwards with these particulate materials. The method and device of the present invention are suitable for filling packs containing doses of powdered medicament contained in recesses of the pack for use in inhalation devices . Background technique [0002] Today, the delivery and distribution of medications can be accomplished in many different ways. In health care, people are paying more and more attention to the possibility of taking (to dose) and distributing powdered medicines directly into the lungs of the user by means of dispensing devices such as inhalation devices, so that the user can both Take prescribed medicines effectively and beneficially. In most cases some form of dosing process is used to prepare the dose to be inhaled. Typically...

Problems solved by technology

Some of the methods and devices described above do not dispense, or do not dispense with sufficient precision, a prescribed dose of powder having less than the volume of the recess containing the dose

Methods and devices suitable for dispensing powder doses having a smaller volume than the recesses are very complex in construction and can only be used for filling recesses deployed in the form of linear patterns or containing some linear patterns such as matrix patterns, but not Filling of cavities arranged in various patterns, such as those arranged in arbitrary and non-linear patterns

None of the methods or apparatuses mentioned above can fill all the blisters or cavities in the tray or package at the same time, requiring multiple repeated filling operations
