Definitions
- the present invention relates to the technical field of packaging, and more particularly to that of packaging and distribution of a semi-fluid or suspended liquid product intended to be stored in a sealed and sterile manner, without the addition of preservative, and to be dispensed in the form of drops using a dispenser assembly provided with a nozzle.
- the invention more particularly relates to a device for packaging and dispensing a sterile product, and which comprises a container intended to contain the product to be dispensed using a nozzle, of the type without air intake, with which the container is provided.
- This tip includes a flexible part in cooperation with a rigid part so that the elastic end of said flexible part moves away from the end of said rigid part when pressure is exerted on the container, thus allowing a portion of product to be expelled, and returns to its initial position under the effect of its elasticity without allowing outside air to penetrate inside the container.
- the characteristic of devices of this kind resides in the construction of the flexible part and rigid part assembly which comprises the end of the dispensing nozzle, in such a way that said assembly allows the exit of the liquid when pressure is exerted on the container itself is on the metering chamber, but opposes any entry of outside air into the container when said pressure ceases or even when the device is no longer stressed but remains subject to external manipulations.
- the difficulty stems from the fact that the tightness of the flexible part and rigid part assembly is delicate and that, to be effective, the contact surface between said elastic flexible part and said rigid part must be large.
- clamping force between the flexible and rigid parts of the end piece does not intervene in the resistance of the assembly to the passage of bacteria.
- the bacteria are very mobile and very small (a few microns) and if they have the capacity to penetrate into the smallest interstice and then to travel towards the interior of the container to which they are attracted, they do not have on the other hand of no force capable of mechanically overcoming the tightening between the two parts of the endpiece.
- the tightening between said two parts can therefore be very low (about 50 to 250 mbar) and thus facilitate their opening by requiring only a low pressure.
- a first object of the invention is to obtain good resistance of the nozzle to the path of bacteria from the outside to the inside of the container.
- Another object of the invention is to allow easy use of the device by requiring only a support force necessary for its operation as low as possible.
- the object of the invention is to remedy the drawbacks of analogous devices of the prior art and to propose such a device which is better suited to the various requirements of the practice than the known devices.
- the latter proposes a device for packaging and distributing a product, generally a semi-fluid liquid or in suspension, comprising:
- a dispensing accessory composed of a rigid part in cooperation with a flexible part, which extends longitudinally around a longitudinal axis to a free end;
- the dispensing accessory allowing the product to be expelled to the outside when one or more side walls of said container are compressed or when at least one actuatable wall of said dispensing accessory is actuated but not allowing air to enter the interior of the container when the device is no longer used, the device further comprising a set of renewal and filtration of the air entering the container after the distribution of a portion or dose of product, said flexible and rigid parts being able to move radially apart from each other by deformation of a contact section, of generally tubular shape, belonging to the flexible part in order to allow expulsion to the outside of said product, said contact section and the rigid part being by default mutually in contact in a discontinuous manner by forming several contact zones including contact zones a xially spaced apart.
- the device makes it possible to distribute portions or doses of product by simple pressures on the walls of the container or on the flexible part of the nozzle with which the accessory is provided, to compensate for the depression thus created in the container by an arrival of air, preferably sterile, through the renewal and filtration assembly, so that it can be actuated easily, without requiring excessive activation force, while effectively opposing penetration bacteria inside the container.
- the contact surface between the rigid part and the flexible part that the end piece comprises distribution is discontinuous in nature and has sufficient annular rods to effectively oppose the progression of bacteria from the outside to the inside of the container, while offering a low resistance to the pressure necessary for the distribution of the product by the opening between said rigid and flexible parts.
- the device comprises one or more metering chambers, and the dispensing accessory, provided with said actuatable wall, allows the product to be expelled towards the outside when said actuatable wall is actuated, preferably by being pushed radially. inwardly, so as to compress the metering chamber or chambers without allowing air to enter the interior of the container when the device is no longer stressed.
- said flexible and rigid parts are in mutual contact in a discontinuous manner, forming at least two sealing zones by annular radial contact, preferably at least three sealing zones by annular radial contact, the contact section of said part.
- flexible forming a labyrinthine seal which extends longitudinally between said metering chamber and the free end.
- the contact section comprises preferably annular sealing rods, which delimit two intermediate circumferential grooves.
- the contact section defines at least three circular successive radial sealing contacts against the rigid part, by said sealing rods.
- the sealing rods are separated by circular spaces.
- the device comprises sealing rods which are separated by recessed spaces and / or notches which do not extend over the entire circumference of the flexible part.
- the rods have a maximum height of 0.3 to 1 mm, measured parallel to the longitudinal axis, said sealing rods not necessarily each having the same height.
- the flexible part surrounds the rigid part which is cylindrical near said free end to form a cylindrical contact surface on which the sealing rods included in the contact section of the flexible part bear radially inwards.
- the flexible part has a wider cross section, preferably gradually widening, as one moves away from the contact section in a direction away from the end. free of the distribution accessory.
- FIG. 1 is a schematic view in axial section of an example of a device according to the invention when not in demand, showing a container in which the product to be dispensed is located, a set for dispensing the compound product of the end of the flexible part provided with rods in cooperation with the end of the rigid part said distribution assembly allowing the product to be expelled outward when the bottle is compressed but not allowing the air to entering the interior of the container when the bottle is no longer used, an air renewal and filtration assembly comprising a filter and a non-return valve positioned in the rigid part of said accessory;
- FIG. 2 is a schematic view in axial section of a device according to Figure 1, when requested, representing the accessory but without the detail of the rods being shown when the walls of the container are compressed and that dose of product is expelled using the dispensing assembly;
- FIG. 3 is a schematic view in axial section of a device according to the invention comprising a nozzle provided with metering chambers when the latter are stressed and a dose of product is expelled by spacing of the flexible part of the rigid part but without the detail of the rods being represented;
- FIG. 4 is a schematic view in enlarged axial section of the end of the dispensing nozzle as shown in Figure 1 showing the detail of the sealing rods and the spaces between them;
- FIG. 5 is an enlarged schematic cross-sectional view of the distributor nozzle at the space between two rods along the axis ZZ '.
- Figure 6 is a view similar to Figure 5 showing the space between two rods reduced to a sector.
- the packaging and distribution device comprises a container 1 in which is contained the product to be dispensed 2, a free space 3 located above the liquid 2, a distribution accessory 15 composed of a rigid part
- the end of said flexible part 8 comprising sealing rods 13, 13a, 13b and 13c, free spaces 14, 14a and 14b, and cooperating with the end of said rigid part 7 in order to allow the product contained in said container 1 to be expelled from the interior of said container 1 when the latter is compressed but not allowing outside air to penetrate into said container 1 when the latter is not more compressed, an orifice 11 allowing the product 2 to pass from the interior of the container 1 to the dispensing nozzle 15, a set of filtration of the renewal air comprising a sterilizing filter 4 associated with a valve 5 which allows outside air renewal to enter the interior of the container after dispensing a drop of product 2 but opposes any air or product 2 from the inside to the outside of the container 1 .
- the device as shown in Figure 2 operates as follows.
- the device When the pressure on the walls of the container ceases, the device is no longer stressed and the elasticity of the end of the flexible tip 8 causes it to return to its initial position and the zone 10 to close.
- FIG. 3 The operating principle of the device as shown in FIG. 3 is identical to that of FIG. 2, but the support is exerted on the part 17 of the flexible end piece 8 at the metering chambers 16 according to the arrows D and From and no longer on the walls of the container 1.
- a valve 18 is placed in the communication orifice 11 in order to oppose the return of the product 2 towards the interior of the container 1 when pressure is exerted on the chambers 16.
- Figure 4 shows the detail of the end of the dispensing nozzle 15 when the device is not stressed.
- the end of the flexible part 8 which cooperates with the end of the rigid end piece 7 is provided with several sealing rods 13, 13a, 13b and 13c which are separated by free spaces 14, 14a and 14b which do not offer no contact between the flexible 8 and rigid 7 parts.
- a pressure P exerted on the product 2 causes it to pass through the channel 9 and the opening of the first rod 13.
- the product 2 then enters the first free space 14.
- This pressure is much lower than the pressure that would be required to open a contact surface equal to the sum of the contact surfaces of all the rods.
- the pressure required to open a rod 13 offering a longitudinal extension of the annular contact surface of 0.8 mm with the rigid part 7 varies from 100 to 300 millibars depending on the relative diameters and the tightening existing between these two pieces.
- the absolute resistance to the progression of bacteria by sealed contact zones between two flexible and rigid parts is illusory and the purpose of a device as described above is to oppose this progression towards the interior as long as possible. container to which these bacteria are attracted and which must remain sterile.
- FIG. 6 shows a free space reduced to an angular sector and does not not extending over 360 ° as shown in Figure 5.
- labyrinth seal (meets in English: "labyrinth seal"), meets this objective and the number of rods, their shape, their dimensions as well as those of the free spaces between said rods can vary without leaving of the scope of the invention.
