Problems solved by technology

[0007] An undesirable problem with known filling units is that, after the container is closed, the liquid therein contains many air bubbles, which may complicate the subsequent use of the liquid
[0008] In addition, the speed of operation of the filling unit described above is not optimal

Embodiment Construction

[0017] exist figure 1 with figure 2 , the number 1 generally indicates single-use containers, especially cartridges for the pharmaceutical industry In the following, specific reference will be made to this type of container, without losing the generality of the invention, since it can be advantageously applied to other containers for liquids in the pharmaceutical industry, such as syringes.

[0018] The cartridge 1 comprises a tubular body 2 closed at the front by a sealing cap 3 which is centrally piercable (i.e. can be penetrated with relative ease by a needle) and closed at the rear by a piston 4 which Acts as a back cover and in use is designed to slide along the tubular body 2 to push the liquid product 5 outwards.

[0019] exist image 3 , the number 6 indicates that it is used to fill figure 1 Part of a filling machine for a cartridge 1 of the type shown.

[0020] The filling machine 6 comprises a feed conveyor 7 designed to feed a set of cartridges 1 through a f...

Abstract

A filling unit (11) to fill a container (1), in particular a cartridge (1), with a liquid product of the pharmaceutical industry having : a dosing head (12), which is arranged in a filling station (S1) and is designed to feed a quantity of product (5) into the container (1) through an open upper end of the container (1); a capping device (18), which is arranged in a capping station (S3) and is designed to insert a closing element into the container (1) and through the open upper end of the container (1); and a sucking device (15) which is arranged in a degasification station (S2) located between the filling station (S1) and the capping station (S3), is designed to engage the open upper end of the container (1) in a sealing manner, and is designed to generate a depression inside the container (1) in an upper volume, which is not occupied by the product (5).

Description

[0001] Citations to related applications [0002] This patent application claims priority from Italian patent application 102019000007150 filed May 23, 2019, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The invention relates to a filling unit for filling containers with liquid products of the pharmaceutical industry. [0004] The present invention finds an advantageous application for filling containers with a liquid product, such as a medicament, in particular a cartridge ( Hereinafter simply referred to as a cartridge), ie a tubular container provided with a sliding piston to allow the liquid product to be injected directly from the inside of said container. The same advantageous application is provided by using other similar containers, such as "ready-to-use" syringes. Background technique [0005] Typically, injections are performed using an empty syringe, which initially draws the liquid drug from the vial; however, thi...
