Definitions

  • the present invention relates to a single-dose spray container, a spray tip and a single-dose spray kit. These elements are disposable or reusable and allow misting with a single-dose container of defined shape or not.
  • Single-dose plastic vials are widely used for the administration of perishable pharmaceutical products or cosmetics and / or requiring several applications per day, in particular because of the transport and use conveniences they offer.
  • these single-dose vials have the disadvantage that the liquid they contain flows in a jet when pressure is exerted on their side wall.
  • the jet is too aggressive, especially in the case of application to the nasal mucosa of infants and children, or the jet is too localized, especially for topical applications of disinfectants or cosmetics.
  • Spray administration is therefore preferred so as to make the contact less aggressive, to increase the area of product applied at one time to the area to be treated and / or to increase the penetration of the product applied in the mucous membranes in particular.
  • Spray tips are described in particular in the following patents: WO 97/07897 , FR 2,840,549 , US 5,855,322 , WO 03/041865 , US 4,415-12 and US 4,020,979 .
  • spraying means the formation of droplets in the form of misting.
  • single-dose vial plastic vials containing the amount corresponding to a single application dose of a liquid product. Such flasks are obtained by extrusion blow-filling.
  • the single dose vials include the Company GILBERT marketed under the PHYSIOMER ® brand.
  • the single-dose container comprises a flexible bottle whose opening is surmounted by a spray tip, said tip comprising a nozzle of generally cylindrical shape, the upper end has a spray opening and the opposite end is extended by a plunger of smaller diameter, said plunger being inserted into the flask through the opening of the flask and the lower part of the nozzle bearing on the upper wall of the opening of the single-dose flask, the nozzle and the plunger being crossed along their longitudinal axis by a through cavity, said through cavity having at the nozzle a droplet generation means, the plunger having a free end mechanically reinforced by a means selected from the group comprising: a beveled shape, a screw thread , a longitudinal through opening forming a crow's foot whose openings open on the oi the free end of the diver, and their combinations.
  • the mechanical reinforcing means of the free end of the plunger facilitate the insertion of the plunger into the opening of a vial by giving it a resistance which makes it possible to avoid the deformation of said end of the plunger at the moment of insertion. This is particularly useful in cases where the tip is intended to be forcibly placed on a single-dose vial. Reinforcement can be provided by a beveled shape of the free end of the plunger. A significant mechanical resistance can also be conferred on the free end of the plunger in that the longitudinal through cavity forms in the lower part of the plunger a crowbar whose openings open symmetrically on the wall of the free end of the plunger . The mechanical strength can also be conferred by a screw thread disposed at the free end of said plunger.
  • the thread is particularly suitable in the case where the tip is intended to be used on single dose vials whose tear opening has a diameter of between 0.2 and 2 mm, preferably between 0.5 and 1, 5 mm and more preferably between 0.8 and 1.2 mm.
  • the combinations of these mechanical reinforcing means make it possible to increase all the more the mechanical resistance to the deformation undergone at the moment of insertion of the plunger into the bottle.
  • the droplet generation means may consist of a longitudinal cavity having zones of different diameters in which is present an element making it possible to force the passage of the product towards the walls of the through-cavity in its zone of larger diameter and an element permitting to force the product towards the center by imposing a swirling motion near the spray opening.
  • These elements can be molded in one piece or may be separate elements inserted into the through cavity of the nozzle.
  • Such droplet generation means may be similar to those marketed by REXAM or MICROSPRAY companies.
  • the shape and size of the droplet generation means are of course adapted according to the nature of the product to be sprayed, in particular its viscosity and the use for which it is intended.
  • the opening of the plunger may be at about one-third of the height of the flask.
  • the container according to the invention is either made in one piece, for example by extrusion blow-filling, or is manufactured in two pieces which are, after filling the bottle, made integral.
  • either the tip and the bottle are molded in one piece or the tip is placed on the opening of a pre-filled bottle.
  • the diameter of the plunger is substantially greater than that of the opening of the single-dose vial so that it is forced in and is not ejected when pressure is exerted on the wall. of the single-dose vial during use.
  • the seal can be improved when the tip has a sealing ring that allows to clamp the free edge of the opening of the bottle on the lower part of the sealing ring.
  • the outer wall of the nozzle may include gripping areas. These gripping areas may be rough areas so that the fingers do not slip when it comes to place the tip according to the invention in the opening of a single-dose vial.
  • plastic material of food grade or pharmaceutical there may be mentioned all families of plastics that can be injection molded, for example, polyethylene, polyethylene terephthalate, polypropylene, etc.
  • the container and the nozzle can take any other form for use and an advantageous embodiment.
  • the invention also relates to a spray tip, said tip comprising a nozzle of generally cylindrical shape, the upper end has a spray opening and the opposite end is extended by a plunger of smaller diameter, said plunger being inserted into the bottle through the opening of the bottle and the lower part of the nozzle bearing on the upper wall of the opening of the single dose vial, the nozzle and the plunger being traversed along their longitudinal axis by a through cavity, said through cavity having nozzle level means for generating droplets, the plunger having a free end reinforced mechanically by a means selected from the group comprising: a beveled shape, a screw thread, a longitudinal through opening forming a crow's foot whose openings open on the wall of the free end of the plunger, and their combinations.
  • the spray nozzle is characterized in that the means for generating the droplets may consist of a longitudinal cavity having zones of different diameters in which is present an element making it possible to force the passage of the product towards the walls of the through cavity in its zone of larger diameter and an element for forcing the product towards the center by imposing a swirling motion near the spray opening.
  • the nozzle is separated from the plunger by a sealing element.
  • This sealing element may be a ring optionally having a slot in its lower part for effective cooperation with the upper edge of the bottle on which the tip may be placed.
  • the outer wall of the nozzle as defined above may, according to a preferred embodiment of the invention, comprise gripping zones that prevent the fingers of the user from sliding at the time of insertion of the mouthpiece in the opening of a single-dose vial.
  • the tip defined above is made of plastic material of food grade or pharmaceutical.
  • the invention also relates to a kit containing a tip as defined above and at least one filled flexible single-dose vial with breakable opening.
  • the single-dose spray container, the spray nozzle, and the spray kit. spraying are useful for the administration of pharmaceutical or cosmetic products.
  • the applications of the devices are numerous.
  • the nozzle may be provided with an atrial cannula to prevent penetration into the ear cavity.
  • This cannula has grooves for the depression of the ear.
  • the nozzle can also be provided with an anti-intrusive collar for applications in the nose of children and infants.
  • Other applications may be topical applications including cleaners, disinfectants such as betadine, eosin, methylene blue, etc.
  • a spray nozzle 1 comprising a nozzle 2 of generally cylindrical shape constituting its upper part and a plunger 3 constituting its lower part which is generally cylindrical in shape with a diameter smaller than the diameter of the nozzle 2.
  • the upper face 2a of the nozzle comprises a central opening 4 by which the product 5 is sprayed.
  • the lower part 2b of the nozzle is bevelled and a sealing ring 6 connects the bevelled part 2b of the nozzle to the plunger 3.
  • the free part of the plunger is beveled 7 and it is provided with a screw thread 8. It also comprises two diametrically opposed openings 9a allowing the entry of the product 5 into the spray tip 1.
  • a spray tip 10 is shown in more detail a spray tip 10 according to a particular embodiment.
  • the spray tip 10 comprises a nozzle 11 and a plunger 12 connected by a sealing ring 13.
  • the spray tip 10 is traversed longitudinally by a cavity 14 through which the product 15 will circulate and whose shape will allow the formation of droplets.
  • the cavity 14 is generally cylindrical in shape, centered along the longitudinal axis 16 of the nozzle 10. In its upper portion 14a it is of very small diameter, for example the order of 1 mm, then its diameter widens to form a shoulder 17, for example of the order of 4 mm, it then has its maximum diameter over its entire central portion 14b which occupies the entire length of the nozzle, then a new shoulder 18 decreases the diameter of the cavity.
  • the diameter for example of the order of 1 mm, remains constant throughout its portion 14c through the plunger.
  • this cavity 14c separates into two cavities 14d in the form of crow's feet opening along the bevelled wall of the plunger.
  • the zone 14b is obstructed by a central element 19 of generally cylindrical shape with a diameter slightly smaller than the diameter of the cavity 14b and having over a portion of its length and over at least a portion of its periphery protuberances 20.
  • Said protuberances 20 are a size such that they fill the space left free between the walls of the cavity 14b and the central element 19. Slots 21 are thus formed around the shutter element 19.
  • the shoulder 17 is shown in detail on the figure 4 on which it is seen that it has on its outer periphery a protrusion 22 and three radial protuberances 23 regularly arranged around the central opening 24.
