CHEMILUMINESCENT CLEARING ELEMENT

  The invention relates to a chemiluminescent lighting element consisting of a tubular container of translucent, deformable material, filled with susceptible chemical liquids, when mixed between

  them, to emit light by chemiluminescence.

  Lighting elements based on the mixture of liquids are already known, in particular according to the following two systems: in the first system, a first liquid solution is contained in a translucent flexible tube, and a second liquid solution is contained in an ampoule or capillary of glass, which floats in the first solution. When the user folds the flexible tube, the glass element is broken and releases the second solution which is then mixed with the first, which causes the light-emitting chemical reaction. In the second system, the two solutions are mixed in advance, immediately emitting light, then placed in a container made of translucent material, and said container is very quickly placed in a freezing chamber, where the low temperature stops the reaction, until the user

  decides to remove it to make use of light.

  Both of these known systems have drawbacks, one of which may be cited. For the first, the fact that the glass is not chemically inert with respect to the solutions used; in the long term, it causes alterations. Furthermore, if the glass container has the shape of an elongated capillary, which is common, there is a danger of breaking it prematurely, during handling. For the second system, the drawback lies, as is easily understood, in the considerable handicap constituted by maintaining a freezing chain generally involving the use of portable refrigerators filled with dry ice, throughout the successive storage operations. , transport and sales, up to

the end user.

2619 1 9 7 2

  The subject of the present invention is another system which overcomes the

  disadvantages of known systems.

  To this end, it provides an illuminating element of the type indicated previously in the preamble, characterized in that the container has a general shape at least partially at least substantially tubular and in that it is associated with a movable sectioning member and control which, on the one hand, in a first active state has the function of constituting, inside the container, two separate enclosures, sealed with respect to each other, separated from one another in an at least substantially tubular part of the container, each filled, respectively, with one of the two liquids, the lighting element then being passive; and which, on the other hand, in a second passive state conferred by the user has the function of authorizing the communication between the two speakers and therefore the mixing of the two liquids, the illuminating element then being able to

  be active and ensure the emission of light.

  According to another characteristic, the element also comprises additional means of separation, mobile, between, on the one hand, a first passive state corresponding to the first active state of the mobile sectioning and control member and, on the other hand, a second active state corresponding to the second passive state of the movable sectioning and control member and in which they have the function of participating in or ensuring the mutual separation of the previously locally deformed walls of the container, in particular up to '' to their original position or close to it, and this by action on

these walls.

  According to another characteristic, the element also comprises additional means for mixing the two liquids, which are mobile between, on the one hand, a first passive state corresponding to the first active state of the mobile sectioning and control member and, on the other hand, a second active state corresponding to the second passive state of the movable sectioning and control member, in which they have

  the function of participating in the mixing of the two liquids.

  As follows from the above, such an illuminating element does not have an internal fragile container capable of being

2619 197

  unexpectedly broken, as is the case of the first known system previously described. In addition, such an illuminating element can be stored at room temperature and does not require a cold chain.

  as for the second known system also previously described.

  The other characteristics and advantages of the invention will be clearly understood with the aid of the appended drawings in which: FIGS. 1 and 1A are two schematic views, respectively in longitudinal section and in cross section of a first variant

  for producing an illuminating element according to the invention.

  Figures 2 and 2A are two similar schematic views of a

second variant.

  Figures 3 and 3A are two similar schematic views of a

third variant, preferred.

  Figure 4 is a schematic view in longitudinal section of a

fourth variant.

  The invention relates to a chemiluminescent lighting element of the type comprising an elongated container 1 of translucent, deformable material, filled with two chemical liquids 2,3 which, by mixing, are

  likely to emit light.

  According to the invention, the container 1 has an overall shape at least partially at least substantially tubular and there is associated therewith a movable sectioning and control member 4 which, on the one hand, in a first active state has the function of constituting , inside the container 1, two separate enclosures 5,6, sealed relative to one another, separated from each other in an at least substantially tubular part 7 of the container 1, each filled, respectively, with one of the two liquids 2,3, the lighting element then being passive; and which, on the other hand, in a second passive state conferred by the user has the function of authorizing the communication between the two speakers 5,6 and therefore the mixing of

26 1919 7 4

  two liquids 2,3, the illuminating element can then be active and

ensure the emission of light.

  In a preferred embodiment, the movable sectioning and control member 4 is constituted by a rigid, pressing, removable member, intended, on the one hand, in its first active state, to be placed on, around and at the outside of the container 1, so as to locally deform it (in part 7), so that its walls 8 thus locally deformed come into reciprocal tight contact; and / or, on the other hand, in a second passive state, to be dissociated from the container 1, the walls 8 thereof, beforehand

  thus deformed can be spread apart.

  The container 1 is made of a material completely inert with respect to liquids 2,3, such as polyethylene. Preferably, it has a tubular shape with a circular cross section

  or other, not only in part 7, but over its entire length.

  This part 7 is generally median or substantially median. The container 1 forms an elongated container, that is to say one whose dimension (axial length) is significantly larger than the others. Thanks to the movable sectioning and control member 4, in the active position, the container 1 is separated into two chambers 5,6 which can be filled respectively with liquids 2,3. Then each of the enclosures 5,6 is closed, in particular at its end 9

by welding.

  In the active state of the movable sectioning and control member 7, the lighting element can be stored, handled, transported,

easily and safely.

  To obtain the emission of light, it suffices, as it results

  from the following description, to move the member 4 into its state

  passive, possibly undoing the fold or folds of the container 1, spreading the walls 8, shaking the container 1, putting in

  works an additional means of mixing.

  The internal face of the container 1, at least in the zone 7 o it

2619 1 9 7

  is locally deformed by the rigid removable pressing member 4, has a surface condition suitable for sealing liquids 2, 3 of

  the element, by simple reciprocal contact over a certain length.

  In particular, this face is smooth, which, combined with sufficient pressure exerted by the member 4, over a sufficient length,

provides the required seal.

  The container 1 has, at least in the zone 7 o it is locally deformed by the rigid removable pressing member 4, a certain elastic deformability. In particular, the container I is more or less monobloc in the same single material over its entire length. Its deformability is essentially such that the walls 8

  can be brought into reciprocal contact thanks to organ 4.

  Preferably, this deformability has a certain elasticity so that, when the member 4 is in the passive state, the container 1 tends to return to its natural shape.

  original or resume this form.

  The movable member 5 of sectioning and control 4 also has the function in its first active state of ensuring the production and maintenance of at least one fold 11 of the container 1, this fold 11 participating in or ensuring the seal between the two enclosures 5, 6. A variant with a single fold in a general U shape is shown on the

Figures 2 and 2A.

  According to a preferred variant, the movable member 4 ensures, in its first active state, at least two superimposed folds 12, 13. By two superposed folds is meant the general S-shape shown in FIG. 3. This variant also has interest to allow easier passage of the organ 4 from one to the other of its two active and passive states. Indeed, it is then sufficient to pull in opposite directions on the two ends of the container 1 to ensure the passage of

  organ 4 from the active state to the passive state.

  The production of one or more folds also has the function of ensuring an increase in the internal volume of the container 1, an increase in volume which is particularly useful for compensating for the increase in pressure which would result, all other things being equal, that is to say at constant volume - of the emission of carbon dioxide following the chemiluminescent reaction. he

  ensues an improvement in the security of the lighting element.

  If the elasticity of the container 1 is not sufficient to ensure, on its own, the spacing of the previously deformed walls 8, the user can facilitate this spacing by manual action. In addition, and preferably, the lighting element also comprises additional means of separation 14, movable, between, on the one hand, a first passive state corresponding to the first active state of the movable sectioning and control member 4 and , on the other hand, a second active state corresponding to the second passive state of the movable sectioning and control member 4 and in which they have the function of participating in or ensuring the mutual spacing of the walls 8 previously locally deformed of container 1, in particular up to their original position or close to it, and this by

action on these walls 8.

  These additional means are preferably constituted by a movable member mounted at least to slide with respect to the container 1. In a particular variant embodiment, the additional spacing means 14 are constituted by a ring or equivalent, rigid, mounted to slide on and outside the container 1, having in cross section an internal profile complementary to the external profile, in cross section, of the container 1, in the area of the movable sectioning and control member 4 in the active state and before deformation by said member 4, the function of the additional spacing means 14 being fulfilled by sliding the ring 14 by force from its passive state to its active state, this sliding having the effect of urging the walls 8 of the container 1 previously deformed, in the direction of spacing to their position, or in the immediate vicinity in particular thereof, initial before deformation and reciprocal contact. In order to ensure the mixing of the two liquids 2, 3, the user shakes the container 1, when the member 4 is in the passive state. If necessary, the handling of the container 1 for the spacing of the walls

26191.97 7

  8 facilitates this mixing. In addition, and if required, the element also comprises additional means 15 for mixing the two liquids 2, 3, which are movable between, on the one hand, a first passive state corresponding to the first active state of the movable member of sectioning and control 4 and, on the other hand, a second active state corresponding to the second passive state of the movable sectioning and control member 4, in which they have the function of

  participate in the mixing of the two liquids 2.3.

  These additional mixing means are preferably constituted by a solid piece housed in the container 1 and capable in its second active state of being moved therein from one to the other and / or between the two enclosures 5, 6 and therefore in the respective liquid (s) 2, 3. In particular, this solid part 15 is, on the one hand, spherical or ovoid, or cylindrical, or cylindrical with rounded ends, or equivalent; and / or, on the other hand, magnetic. This massive part 15 is therefore displaced by gravity,

  by centrifugal force, by magnetism or other.

  The use of a magnetic part allows its displacement by means of a magnet. In general, the very mass of the part ensures its displacement

  during agitation given to container 1.

  Finally, the movable sectioning and control member 4 is a ring or the like, or a part in the general shape of a horseshoe, or a staple, or a screw clamp, or a clips or a

removable clamping or equivalent.
