Definitions

  • the present invention relates to the field of devices for dispensing substances, such as aerosols or viscous materials.
  • distributors comprising a container body, a reservoir made of flexible material, which contains the substance to be dispensed, a dispensing head capable of being controlled by the opening or closing, and elastic means formed by two elastic blades placed respectively on either side of the reservoir, to exert a permanent pressure on the latter and allow a distribution of said substance on a single command at the opening of the distribution head.
  • Document EP-A-0 388 270 describes improvements to the dispenser proposed in the aforementioned document EP-A-0 300 886. According to these improvements, the elastic means further comprise an elastic sheath stretched over said blades.
  • the marquee 4 is generally crimped onto the container body 1, when these elements are metallic. Where appropriate, the marquee 4 can be welded or glued to the container body 1 when these elements are made of plastic or glass. These various assembly techniques prohibit any disassembly.
  • the present invention now aims to improve existing dispensing devices.
  • An important object of the present invention is to provide a new easily removable dispenser.
  • Another important object of the present invention is to provide a new dispenser which can be refilled.
  • the dispensing device according to the present invention thus formed is easily removable because the assembly formed by the reservoir, the dispensing head, the bottom wall and the elongation limiter constitutes an insert easily separable from the container body.
  • the container body 100 can be the subject of numerous embodiments. It can be formed for example of a solid wall cylinder, as shown in Figures 13 and 15, of revolution or not around its central axis 102.
  • the container body 100 may for example have a polygonal section considered in a plane transverse to the aforementioned axis 102.
  • the body 100 preferably has a section constant over its entire length.
  • the body 100 can be formed of any suitable material, such as for example plastic or metal, in particular iron, aluminum, even cardboard, glass.
  • the body 100 can be formed of a simple helical spring centered on the axis 102.
  • the body 100 serves as a radial expansion limiter for the tank 200.
  • the reservoir 200 can be formed of a blind pocket as described in the aforementioned documents EP-A-0 300 886 or EP-A-0 383 270.
  • the reservoir 200 is formed from an extruded elastic tube.
  • an extruded tube represents, compared to a blind pocket as described in documents EP-A-0 300 886 and EP-A-0 383 270, a big saving in tools, the replacement of molds by channels and the possibility of adapting without limitation the length of the tank.
  • the use of an extruded tube allows, as will be explained below, after dismantling the dispenser, to rinse and sterilize the tank / tube 200, for example by a flow of steam and then of sterile hot air.
  • the extruded tank 200 is advantageously made of butyl.
  • the dispensing head 300 can be formed from any suitable structure known to those skilled in the art. It advantageously comprises a box 302 which houses a valve biased by spring against an associated seat and a control button 304 capable of being actuated by a user to move said valve from its seat and thus free a through passage to authorize the distribution of substance.
  • the housing 302 is provided on its outer periphery with an annular bead facilitating the fixing of the dispensing head to the marquee 400.
  • the marquee 400 can also be the subject of numerous embodiments. It can be made of metal or plastic.
  • the marquee 400 is formed of a single piece whose external cross section is identical to that of the body 100.
  • the marquee advantageously has an annular recess 402, on its external surface to allow engagement of the marquee 400 on an axial end body 100.
  • the marquee 400 has a chamber 406 complementary to the housing 302 of the head 300 and which opens onto its upper surface 408.
  • the marquee 400 is further crossed by a passage 410, preferably in the form of a slot, which connects the lower surface 412 of the capital to said chamber 410.
  • the passage 410 advantageously has inclined chamfers 414 on the side of the chamber 406.
  • the passage 410 is intended to receive the upper end of the reservoir 200 and of the elongation limiter 800 while letting the material to be distributed pass.
  • the bottom wall 500 is intended to be placed against the bottom of the body 100. It is also adapted to be fixed on the lower end of the tank 200.
  • the bottom wall 500 can be the subject of numerous embodiments suitable for this purpose.
  • the bottom wall 500 comprises a clamp structure adapted to be clamped on the lower end of the tank 200 in order to fix this and simultaneously ensure the tightness of the tank 200.
  • the bottom wall 500 comprises a disc 502 generally plane at rest which has a cutout 504 passing through according to its thickness, in the general shape of H.
  • the core 506 of the cutout 504 is produced according to a diameter of the disc 502.
  • the two wings 508 of the cutout 504 located respectively on either side of the core are symmetrical with respect to the diametral plane containing the core 506. These wings 508 converge towards their free end.
  • two fold lines 510 mutually parallel and parallel to the core 506, which respectively connect the free ends of the wings 508.
  • the structure 500 thus formed is made of elastic material, for example metal or plastic.
  • the spring blades 600 and 700 are of identical structure. They are placed respectively on the side and on the other side of the reservoir 200 and preferably take support on the internal surface of the body, to operate on the reservoir 200 a constant pressure capable of authorizing the delivery of the substance contained in the reservoir 200, when the dispensing head 300 is open.
  • blades 600 and 700 can comply with the provisions described in documents EP-A-0 300 886 and EP-A-0 383 270. These blades 600 and 700 are thus preferably formed from spring steel blades with a thickness of a few tenths of a millimeter and a rectangular outline.
  • the elongation limiter 800 is intended to limit the spacing between the marquee 400 and the bottom wall 500, in particular when filling the reservoir 200.
  • the elongation limiter 800 is therefore formed of a non-elastic element, of so that this limiter cannot be susceptible to elongation.
  • the elongation limiter 800 is made of flexible material.
  • the elongation limiter 800 can thus be formed for example based on metal or plastic.
  • the elongation limiter 800 can be the subject of numerous embodiments. It can be formed for example of a simple band housed in the tank 200 to be fixed both on the marquee 400 with the upper end of the tank 200 and on the bottom wall 500 with the lower end of the tank 200.
  • the elongation limiter 800 is formed of a plastic tube, for example of polyethylene, housed in the tank 200.
  • the tube forming the elongation limiter 800 is clamped at its upper end between the marquee 400 and the housing 302 of the dispensing head 300, and at its lower end in the bottom wall 500. Consequently, so as not to disturb the passage of the material to be dispensed, when opening the head 300, the tube 800 must be provided with at least one passage passing through its thickness.
  • the tube 800 is provided with a plurality of longitudinal slots 802 which extend substantially over the entire length of the tube, with the exception of crowns located at the upper and lower ends of the tube 800, where it must be pinched respectively between the marquee 400 and the housing 302 and in the bottom wall 500.
  • the tube 800 comprises a single through hole 804, near its lower end.
  • This second embodiment is adapted to be used in the case of dispensing a substance containing a propellant gas as a mixture, so that the gas confined in the upper part of the tank 200 cannot pass directly into the dispensing head 300 while authorizing on the other hand the passage of the substance by the lower orifice 804.
  • the dispensing device can be supplemented by a covering capsule clipped into the bottom of the body 100.
  • the body 100 is preferably provided at its lower end with a recess 104 complementary to said capsule.
  • the elongation limiter 800 is placed in the tank 200.
  • the upper end of the reservoir 200 and of the elongation limiter 800 is placed in the slot 410 of the marquee 400 and immobilized therein by engagement of the housing. 302 in chamber 406.
  • the fixing of the head 300 in the marquee 400 can be obtained by any conventional means suitable, for example by expanding the marquee 400 on the housing 302, as is known per se.
  • the blades 600 and 700 are then placed respectively on either side of the reservoir 200.
  • Preferably an elastic sheath 900 is further tensioned on the blades 600 and 700.
  • the assembly thus formed is then placed in the body 100, the base of the marquee 400 being engaged in the upper end of the body 100.
  • the lower end of the reservoir 200 and of the elongation limiter 800 is then pinched in the bottom wall 500 placed at the lower end of the body 100, according to the previously described procedure.
  • the operational device represented in FIG. 15 is then obtained.
  • the marquee 400 and the bottom wall are connected by the elongation limiter 800.
  • the body 100 limits the radial expansion of this reservoir.
  • the radial expansion limiter for the reservoir can advantageously be formed from a helical spring 100 as shown in FIG. 16.
  • This technique has obvious economic advantages compared to the use of an external housing formed by '' a continuous wall cylinder since the use of a spring 100 allows different diameters and involves only fairly simple tooling modifications with lengths on demand to result in a unit cost several times less than a cylinder of any material .
  • the spring 100 can be coated with a heat-shrinkable sleeve.
  • provision may be made for conditioning the dispensing device comprising the reservoir 200, the dispensing head 300, the marquee 400, a radial expansion limiter formed by a spring 100, the bottom wall 500 and preferably the elastic blades. 600, 700 and the sheath 800 in the form of a refill adapted to be introduced into a more or less luxurious over-box kept by the consumer, comparable to the box 100 shown in the attached figures. Once empty, one can consider returning said refill to a conditioner for refilling.
  • the elasticity of the spring 100 protects the dispensing device against shocks during multiple transports.
  • the device comprises two biasing blades 600 and 700 and a sheath 900
  • these elements can if necessary be removed, if the intrinsic elasticity of the reservoir 200 allows it, or even used in combination with a propellant.
