Definitions

  • the present invention relates to a refill device for a refillable spray dispenser and to a manually operated refillable spray dispenser.
  • These devices comprise a bottle containing an aqueous solution of the product, which has a mouthpiece with a threaded neck on which a lever actuated sprayer is screwed.
  • the empty bottle may be unscrewed and replaced by a replacement bottle, whereas the sprayer may be reused.
  • Aqueous solution products generally used for home and gardening purposes, have a water content (by volume) of more than 98%.
  • an alternative solution to bottle replacement may consist in purchasing the active ingredient and reconstituting the product in the bottle by mixing the active ingredient with water.
  • US 4,705,191 discloses a spray dispenser that may be refilled by adding water to an active ingredient refill.
  • the bottle has a second threaded neck opening which is used to introduce water and screw a refill cartridge whose content is discharged once the cartridge has been wholly screwed.
  • this refill can be only mounted to the bottle when it is actually used to prevent any accidental and undesired discharge of the refill content in the bottle, due to excessive tightening of the refill.
  • the object of this invention is to solve at least some of prior art problems.
  • Numeral 1 generally designates a refillable spray dispenser comprising a bottle 2 and a lever actuated sprayer 3.
  • the bottle 2 has two threaded necks 5, 6, which act as openings in communication with the inside of the bottle.
  • the first threaded neck 3 has such a size and shape as to facilitate grasp thereof by users and the lever actuated sprayer 3 is screwed thereon.
  • a refill device 4 is screwed onto the second threaded neck 6.
  • This solution allows to use the bottle 2 and the lever actuated sprayer 3 several times, by only replacing the refill device 4 and further allows to complete the refill operation and add water without removing the lever actuated sprayer 3 from its seat.
  • the refill device 4 comprises a generally tubular external element 7 and a generally tubular internal element 8, at least one portion thereof sliding axially in the generally tubular external element 7.
  • the generally tubular external element 7 has an end closed by a pressure-rupturable wall 9 and is coaxially joined at the other end to a nut screw 13, for example by means of a flange 10, and is adapted to be screwed onto the second threaded neck 6 of the bottle 2.
  • the generally tubular internal element 8 has an end 12 closed by a wall, which is adapted to rupture the wall 9 of the generally tubular external element 7.
  • the two generally tubular elements 7, 8 When the two generally tubular elements 7, 8 are joined together, they define a chamber containing a granular or liquid refill, which is designed to be diluted with water to provide a final product to be sprayed.
  • the refill device 4 further includes means 16, 17 which are adapted to prevent removal of the generally tubular internal element 8 from the generally tubular external element 7.
  • the end of the tubular internal element 8 which comes out of the tubular external element 7 has no cover or mechanical protection elements.
  • the device 4 further comprises removable safety means 14 for preventing the wall 9 of the generally tubular external element 7 from being ruptured, as long as there is no need to use the refill.
  • the generally tubular internal element 8 is allowed to slide axially by removal of the means 14.
  • Retainer means 20 are further provided to stop the motion of the generally tubular internal element 8 once the wall 9 has been ruptured.
  • An end stop for the generally tubular internal element 8 is thus defined, which prevents it from further sliding when the wall 9 has been ruptured.
  • the removable safety means 14 preferably include a safety ring pull 18, which may have a tab 19 to facilitate the pull-off of the ring 18.
  • the safety pull ring 18 interferes with a shoulder surface 20 that is integral with the generally tubular internal element 8.
  • the closed end 12 of the generally tubular internal element 8 may have a relief valve 15.
  • the relief valve 15 allows the release of gases or vapors developed by the product in the bottle 2.
  • the relief valve 15 consists of a rubber disk having a normally closed hole in its center, which opens any time the internal pressure exceeds atmospheric pressure.
  • the means 16, 17 for preventing removal of the generally tubular internal element 8 preferably consist of circular protrusions on the inner surface of the generally tubular external element 7 and on the outer surface of the generally tubular internal element 8 respectively.
  • Two circular protrusions 16, 17 are preferably provided on at least one of the two generally tubular elements 7, 8, and are spaced apart substantially by the stroke of the generally tubular internal element 8.
  • the first of these circular protrusions prevents removal of the generally tubular internal element 8 when the refill device has not yet been used, whereas the second prevents removal of the generally tubular internal element 8 after use of the refill device 4.
  • the presence of the removable safety means 14 and the means 16, 17 allows to decide exactly when to use the refill device 4, which may also act as a closing cap for the threaded neck 6.
  • the sliding end 11 of the generally tubular internal element 8 (which faces the inside of the generally tubular external element 7) preferably has a sharp-edged section, e.g. an inclined section.
  • the wall 9 preferably has a thickness of not more than 0.4-0.5 mm.
  • the wall 9 may only have a thinner portion only, e.g. an annular recess, to form a predetermined rupturing portion.
  • the retainer means 20 preferably consist of a portion of the generally tubular internal element 8 having a larger radial size than the generally tubular external element 7.
  • the portion of the generally tubular internal element 8 having a larger radial size may be formed of a plurality of radial tabs 20.
  • the generally tubular internal element 8 is made of polypropylene and the generally tubular external element 7 is made of polyethylene.
  • the harder material of the generally tubular internal element 8 provides resistance to user pressure and to the breaking of the wall 9.
  • the bottle 2 is preferably blow formed from synthetic resins.
  • the generally tubular elements 7, 8 are preferably made of a transparent material.
  • the partial projection of the refill 4 from the bottle 2 allows to ascertain whether the liquid or solid compound is present or not in the refill device, and to monitor discharge of the compound during use of the refill device.
  • the generally tubular elements 7 and 8 have a circular section.
  • the generally tubular internal element 8 is able to slide in a helical path within the generally tubular external element 7.
  • the wall 9 is ruptured by a screwing motion.
  • the second neck 6 is preferably located at such a distance from the first neck 5 that the space above the second neck 6 does not interfere with the lever actuated sprayer 3.
  • This feature facilitates mounting and removal of the refill device.
