Problems solved by technology

[0004] However, these movable or deformable airtight devices are very complicated, and the manufacture and assembly of these devices on the appliance is delicate and expensive work.
[0005] Furthermore, these devices do not guarantee the dispensing of liquid drop after drop, which is a major drawback for products whose dosage is strictly regulated
[0006] In addition, some appliances do not have the function of entering air, which will cause deformation of the container, thus requiring a flexible container structure
Finally, other appliances do not ensure filtration of the airflow drawn into the container when the dose of product is discharged and then enters the air.
This would create a substantial risk of staining or contaminating the product

Embodiment Construction

[0026] See attached picture, figure 1 appliance shown, with Figure 2 to Figure 4 The apparatus shown is the same, designed for the packaging and dispensing of sterile liquid products.

[0027] The appliance comprises a container (not shown) on which a nozzle E is mounted.

[0028] The nozzle E has a flange C connected to the container, and an internal pipe 1 whose upstream end 1a communicates with the container and whose downstream end 1b opens outward through a vent hole 10 .

[0029] The duct 1 is at least partially blocked gas-tight with an insert 2, preferably made of a porous material.

[0030] More precisely, this porous material allows the insert 2, on the one hand, to ensure the dosage of the product by slowing down the outward flow of the product when the container is pressurized, and on the other hand, when the container is pressurized back to atmospheric pressure. At the same time, the filtration of inhaled air is ensured.

[0031] The resulting air inlet preve...

Abstract

The container has a top (E) with an inner duct (1) linked to the container at one end and to an outlet (10) at the other. The duct is at least partially closed by an insert (2) with a selective porosity which permits a controlled flow of the product outwards on the one hand and a filtration of indrawn air on the other, holding back contaminants and / or biological pollutants. The top is covered by a protective cap (3) with a seal for the outlet (10), e.g. in the form of an inner seal lip (30) which fits round the outlet, or a projection which fits into the outlet aperture when the cap is put in place over the top.

Description

technical field [0001] The invention relates to a device for packaging and dispensing sterile liquid products, in particular ophthalmic medical products. Background technique [0002] Such appliances already exist, such as the one formed by the subject matter described in patent application number FR9600120. [0003] In particular, these devices include a product container on which is mounted a nozzle having an internal conduit with an upstream end communicating with the container and a downstream end of the conduit opening outwards through a vent. Generally speaking, the inner pipe is plugged airtight by means of the valve at the level of the vent hole on the one hand and by means of the elastically deformable inner sealing flange on the other hand. [0004] However, these movable or deformable airtight devices are complex, and their manufacture and assembly on the appliance is delicate and expensive work. [0005] Furthermore, these devices do not guarantee the dispensin...
