Definitions
- the invention relates to a lamp designed to be introduced into a container, in particular to apply thereto a photonic treatment aimed at ensuring decontamination of the interior of the container by emission of a luminous flux.
- Patent application FR 2 774 912 describes a method for sterilizing hollow containers (for example a preform or a bottle): a device for injecting a sterilizing agent, for example hydrogen peroxide, is introduced into the hollow body. After the sterilizing agent has left for a while, it is removed by drying the hollow body (when the agent is liquid).
- a sterilizing agent for example hydrogen peroxide
- the blowing of the preform and the filling are carried out downstream in a sterile environment.
- the decontamination operation can also be carried out by hot peracetic acid directly in the bottles, after blowing.
- Document FR 2 917 624 describes such an operation, for example. It should be noted, however, that the bottles undergoing such treatment must be thick enough to withstand the heat. Such a treatment is therefore not suitable for many bottles whose weight tends to be reduced more and more and whose walls are increasingly thin.
- preforms can be disinfected by e-beam, before blowing the preforms and filling the bottles.
- the e-beam is a beam of electrons that is projected onto a surface to be decontaminated. This technology makes it possible not to use chemicals. It should however be noted that, once the preforms have been decontaminated, the blowing and filling of the bottles must always be carried out in a sterile environment.
- the document FR 3 037 247 describes an example of implementation of such a technology.
- decontaminating lamps are also known, such as that described in American patent US 5,753,996 which proposes a solution to facilitate the gripping of the lamp in order to promote its release when it is connected, for the change for example by another lamp when it is defective.
- Document US 6013918 proposes an alternative embodiment of a decontaminating lamp, in particular U-shaped, which makes it possible to deactivate microorganisms in a food product, pharmaceutical product, etc., to extend its lifespan.
- the invention aims to provide an alternative to known devices or methods, which can be implemented both for aseptic application and for ultra-clean application of containers / containers.
- a container will be understood to mean any hollow object having an access opening inside the container. It can be, for example, a bottle, a flask, a preform, a jar, a metal box, etc.
- the invention aims to provide an alternative to the use of chemical agents.
- the invention relates to a lamp to be introduced into an object, as defined by the claims.
- the lamp is designed in particular for decontamination of said object, comprising: - a tube, which extends in a rectilinear direction, having first and second tube ends, capable of diffusing a luminous flux, - two electrodes fixed inside the tube, each of the two said electrodes being fixed to one end among the two said first and second ends of the tube, - an electric device for supplying the electrodes, electric voltage vector between the two said electrodes.
- the lamp according to the invention is remarkable in that:
- the two electrodes have different lengths, one of the two electrodes having a short length and being fixed to said first tube end and the other of the electrodes having a long length and being fixed to said second tube end, said long electrode extending over a length of tube and having an electrode end located at a distance from said second tube end, - at least one radial support element being fitted around said length of tube in which said very long electrode extends, said at least one radial support element having at least two peripheral contacts on said tube, said at least two contacts devices being spaced from each other by a distance at least twice equal to the diameter of said tube.
- electrode will be understood to mean an element or a set of elements capable of generating a plasma and which extends (or extend) between an electrical contactor and an emitting end: in other words, an electrode within the meaning of the invention comprises an element or a set of elements located between a first end (of the element or of the set of elements) forming an electrical contactor and a second end (of the element or of the set of elements) which is immersed in a gas.
- the invention can be implemented in an industrial production line or in a shop where, for example, it would be proposed to fill containers that have already been used and washed, in order to ensure internal decontamination of the containers before to refill them.
- the presence of the radial support element makes it possible in particular to fix the lamp in an industrial installation
- the lamp according to the invention may also include the following features, taken separately or in combination:
- said at least one radial support element preferably comprises at least two peripheral seals and an outer sleeve for radial support, said two peripheral seals being positioned between said tube and the sleeve, said sleeve further enabling said lamp to be gripped, said at least two peripheral seals corresponding to said at least two peripheral contacts and being capable of collapsing between said tube and said sheath,
- the lamp according to the invention advantageously comprises an insulating sleeve positioned at least partially between said sheath and said tube, said insulating sleeve extending over at least part of said length of tube comprising said very long electrode and extending around said chamber comprising said electrical device,
- said electrical device advantageously comprises a first rigid and conductive element, to which is fixed said very long electrode, a second rigid and conductive element, projecting from a free end of the sheath, said first and second rigid and conductive elements being coaxial, received in said chamber and interconnected by a flexible electric cable allowing radial movement of said first rigid element in said chamber,
- the sleeve advantageously comprises a part for manual connection of said lamp to an external device, the external device comprising a housing for said manual connection part of the sleeve, said manual connection part of the sleeve comprising a radial shoulder projecting towards the outside of the sheath, capable of coming into position against a contact surface of said external device in the vicinity of said receiving housing, said shoulder receiving a peripheral seal capable of coming to be crushed against said contact surface of said external device, said part of connection of the sheath further comprising at least one protruding peak capable of moving in a guide rail/internal thread provided in said reception housing,
- said shoulder preferably has a visual element, able to come opposite a second visual element carried by said external device when said connecting part of said sheath is correctly inserted into the receiving housing of said external device,

- said at least one electrical wire or said mesh is held in position on the outer wall of said tube,
- the tube is preferably made of quartz.
- the light emitted by the lamp is advantageously a decontaminating pulsed light.
- the invention also relates to an installation comprising at least one lamp as defined above, said lamp being mounted in an external device, said external device being mounted so as to move in a direction parallel to the axis of said lamp.
- the invention also relates to an installation comprising at least one lamp as defined above, said lamp being mounted in an external device, said installation comprising at least one support for a hollow object, said support being mounted so as to move in a direction parallel to the axis of said lamp.
- FIG. 1 is a side view of a lamp according to the invention.
- FIG. 1 is an axial sectional view AA of the lamp shown in ,
- FIG. 1 is a side view of an installation according to the invention, the lamp being mounted on a mobile device, the lamp being illustrated outside an object,
- FIG. 1 is a side view of the installation shown in ; the lamp being inserted into the object, and
- FIG. 1 is a side view of another installation according to the invention, where the device carrying the lamp is fixed and where the object is positioned on a mobile support.
- FIGS 1 to 3 illustrate a lamp according to an embodiment according to the invention.
- the lamp is designed to decontaminate the interior of objects such as bottles, or other hollow containers having an opening.
- the lamp shown in as a whole comprises a straight tube 1, which extends in a rectilinear direction, capable of diffusing a luminous flux.
- the shape of the tube that the lamp has is essential so that the light radiation it emits can reach the bottom of the container in which it is inserted.
- the tube of the lamp must be long enough so that, when it is immersed in the vial, the end of the tube is close to the bottom of the bottle.
- the tube 1 is preferably of circular section, but a tube of square or rectangular section could be envisaged without departing from the scope of the invention.
- a tube 1 of circular section will however be easy to insert into the neck of a circular section of a bottle.
- Tube 1 also shown in , has a first end 11 and a second end 12.
- the first tube end 11 is free (i.e. it is not connected to anything). It is closed by the same material in which the side wall of the tube is made.
- the tube is made of quartz and the light emitted by the tube is decontaminating pulsed light, such as high-power UV-rich radiation.
- the lamp according to the invention could be made of glass (another material allowing light radiation to pass) and the radiation emitted by the lamp could be different from UV radiation, without however departing from the scope of the invention.
- the end 11 of the tube 1 is thus made closed by a wall allowing the decontaminating radiation to pass. Also, when this end 11 of tube 1 is placed in an object (that is to say inside an object), the radiation also passes through this end, as close as possible to the bottom of the object.
- End 12 of the tube is not free, as opposed to end 11 free.
- the tube 1 comprises two electrodes, fixed inside the tube 1: a first electrode 21 is fixed in the vicinity of the first tube end 11 and a second electrode 22 is fixed in the vicinity from the second tube end.
- the lamp also comprises a device 2 for supplying the electrodes, which carries the electric current (electric current vector) to the electrodes ( ).
- the two electrodes do not have the same length: the electrode 21, located at the free end 11 of the tube 1 is shorter than the electrode 22 located close to the end 12 of the tube 1.
- the electrode 22 extends over a longer length L1 of tube 1: in the context of the example illustrated, the electrode 22 is up to seven times longer (or substantially up to seven times longer ) that the electrode 21 which itself extends over a length L2 of tube (on the , the length L1 is three times longer – or approximately three times longer – than the length L2).
- Electrode 22 is flush with the end of a sheath 3 (presented later) and that the electrode extends between the end of sheath 3 and the end 12 of tube 1.
- the length L1 corresponds to a long length of tube while the length L2 corresponds to a short length of tube.
- the second electrode 22, which extends over the long length L1 of tube 1, has an electrode head 23 – the first electrode 21 also has an electrode head 24.
- the second electrode 22 extends between an electrode head 23 at its free end, the electrode head 23 being at a distance from the end 12 of the tube 1 and from its other electrode end which acts as a contactor: this distance corresponds to the great length L1 of tube over which the second electrode 22 extends.
- the electrode 23 comprises all the elements included between the electrode head 23 (at one end) and the part forming the contactor (at its other end, placed at the end of the tube).
- the lamp also comprises an outer radial support element for the tube 1, fitted around the tube 1 over the length of the tube L1 accommodating the second electrode 22.
- this radial support element comprises an outer radial support sheath 3, which extends at least over the length of the tube L1: it thus encloses the part of the tube 1 in which the second electrode 22 extends, as well as the end 12 of the tube 1.
- the sheath 3 thus offers protection to the end 12 of the tube and to the part of the tube 1 comprising the electrode 22. It provides external stiffening to the tube, thus preventing it (and for example) from deforming over the length L1: the tube can thus be mounted, for example, on a carousel as part of an industrial production line, because the sleeve 3 partially protects the tube and provides additional rigidity over a length of tube: the tube is thus maintained on a segment
- Maintaining the tube over an entire segment makes it possible to implement the lamp in an industrial installation, of the carousel type, because maintaining it on a segment avoids a possible loss of coaxiality: in fact, when an element is maintained by a point on a carousel driven in rotation, it may happen that the centrifugal force has an impact on the coaxiality of this element (its end may, for example, become off axis. By holding the object (in this case the tube) not by a point but on a segment, the loss of coaxiality is avoided.The sheath thus performs this function.
- the sheath 3 is also useful for fixing the lamp in machines, such machines allowing for example to move the lamp in an axial direction, to introduce it into a hollow container or remove it from the container.
- the sheath 3 does not directly touch the wall of the tube: two peripheral O-rings 41 and 42 are also fitted around the tube 1, at least over the length of the tube L1, between the wall of the tube 1 and the wall of the sheath 3.
- the two O-rings 41 and 42 are spaced apart by a distance at least equal to twice the diameter of tube 1.
- the two O-rings 41 and 42 are elastically deformable and have several functions: they serve as points of support on the tube, allow a slight movement of the tube 1 (along the length L1 - by crushing) in the sheath 3 and they allow a sealing between the potentially humid exterior of the lamp and the interior of the lamp. They thus make it possible to maintain a dry environment in the lamp holder to prevent the lines of leakage from being shortened.
- An insulating sleeve 4 can also be provided between the sheath 3 and the tube 1, as can be seen in particular on the .
- the sleeve 3 extends beyond the end 12 of the tube 1 and thus makes it possible to form a chamber 5 axially adjacent to the part of the sleeve 3 which receives the end 12 of the tube 1.
- Chamber 5 accommodates at least part of electrical supply device 2 for the electrodes of the lamp (see FIGS. 2 and 3).
- the insulating sleeve 4 is positioned at least partially between the tube 1 and the sheath 3. It extends around the chamber 5 and over at least a part of the tube 1 which accommodates the electrode 22.
- said power supply device 2 comprises a first rigid and conductive element 51, to which is fixed said very long electrode 22, as well as a second rigid and conductive element 52, projecting from a free end of the sheath 3 ( ).
- the rigid and conductive elements 51 and 52 are received in the chamber 5, placed at the ends of the chamber 5 and they are conductive and coaxial.
- the first rigid element 51 is made in one piece by two coaxial hollow cylinders 53 connected by a solid radial wall 54.
- the second rigid element 52 is made by a solid cylinder 55, having a radial shoulder 56 and secured to a cylindrical hollow 57 at one of its ends.
- the two rigid and conductive elements 51 and 52 are received in the chamber 5 and they are interconnected by a flexible electric cable 58, allowing radial movement of the said first rigid element 51 in the said chamber 5.
- the electrical supply of the second electrode, fixed in the first rigid element 51, is thus carried out from the outside of the lamp, by means of the second rigid element which comes out of the free end 30 of the sheath 3.
- sheath 3 is grounded.
- three electric wires 59 could be provided, running outside the tube 1 from the electrode 21 of short length to the said grounded radial support (sleeve 3 in our example).
- a rigid conductive strip could be provided, spaced from the tube, which would ensure the link between the radial support and the electrode 21.
- This conductive strip could extend in a direction parallel to the axis of the tube, or in a direction other than a parallel direction, for example to adapt to technical constraints specific to a given application.
- short electrode 21 is connected to sheath 3 (therefore to the element grounded radial support) by means of at least one mesh of electric wires which would run outside the tube 1 against its side wall.
- sheath 3 therefore to the element grounded radial support
- Such an embodiment would make it possible to contain the pieces of a broken or chipped tube, which would prevent pieces of a broken or chipped tube from falling into a hollow container into which the lamp according to the invention would be introduced.
- the electrical wire(s) or the mesh is maintained punctually on the outer wall of said tube (that is to say maintained by holding points), for example by means of rings threaded around the tube.
- the electrode anode
- the for example shows an external device 7, to which the lamp shown in Figures 1 to 3 is connected.
- the external device 7 can be a device fixed to a carousel or to a machine 8 which provides movement of the lamp, to introduce or remove it from a container 9 (any hollow object having an opening) and to accompany the movement container on an industrial production line, for example.
- the sheath 3 comprises a part 6 for manual connection of said lamp to the external device (see figures 1 and 3): indeed, one of the advantages of the invention is that the lamp can be assembled and disassembled without tools on the external device 7, which saves time when the lamp needs to be replaced or disassembled for inspection.
- the external device 7 comprises a housing for said manual connection part 6 of the sheath 3.
- connection part 6 comprising a shoulder 60, radial and projecting towards the outside of the sheath 3, which is capable of being positioned against a contact surface 70 of said exterior device 7 (see FIGS. 4 or 5).
- the shoulder radially receives a peripheral O-ring 61, which is able to come crashing against said contact surface 70 of said external device7
- This seal is used to seal the electrical compartment.
- connection part 6 of the sheath 3 may comprise projecting peaks, able to move in a guide rail provided in said reception housing of the external device 7.
- the guide rail is preferably helical.
- Such an embodiment with studs makes it possible to tighten and loosen the fixing of the lamp on the external device, which leads to the compression of the peripheral seal 61 on the surface 70 of the device 7, with a view to guaranteeing the tightness of the lamp. .
- the shoulder 60 To allow someone to visualize a good connection of the lamp to the external device, provision is made for the shoulder 60 to have a visual element, able to come opposite a second visual element carried by said external device when said part of connection of said sheath is correctly inserted in the receiving housing of said external device.
- Such a visual element can be a pattern in relief (or not), representing for example an arrow.
- part 6 it is then sufficient, to connect part 6 to the external device, to insert part 6 into the housing by inserting the studs in the internal rails of the housing, then to push part 6 into the housing by turning until the markers (visual element carried by the external device) come opposite the visual markers of the connection part 6.
- the external device not only makes it possible to supply the lamp with electrical energy (to diffuse the light radiation) but also to cause the lamp to move, for example to insert it into a hollow object (such as a bottle) or to release it from the object, or to accompany the object in a displacement movement.
- a hollow object such as a bottle
- FIGS. 1 to 3 An installation is thus provided where the lamp shown in FIGS. 1 to 3 is mounted in an external device 7 shown in FIGS. 4 and 5, where the external device 7 is mounted so as to move in a direction parallel to the axis of said lamp (for an up and down movement of the lamp).
- Another installation is also planned, shown in , where the lamp is mounted in an external device 7', the installation comprising at least one support 90 for a hollow object 9, said support 90 being mounted to move in a direction parallel to the axis of said lamp.
- the displacement movement of the support 90 is ensured by an 8' machine.
- the device 7' is immobile: it is the object that is moved to ensure the introduction of the lamp.
- the lamp could be equipped with an energy supply system comprising a battery, or an electrical wire for connection to the network, without departing from the scope of the invention, for manual use of the lamp.
- the lamp according to the invention can be used either manually or automatically by being fixed on a machine.
- the lamp can be easily connected manually without tools, which saves time when it is necessary to change the lamp.
